Is it time for case formulation to outweigh the classical diagnostic 
classification in child and adolescent psychiatry?

How does the clinician weigh, sort and summarize all 
the information gained during the clinical 
assessment? How does the clinician ensure that the 
amount of information is summarized in a way that 
makes sense for the child and family while providing 
a basis for planning treatment? 
Most clinicians will probably agree that 
information gained from standardized testing – as 
such testing focuses mainly on symptoms and results 
in diagnostic categories – can only be complementary 
to the overall clinical assessment. However, the more 
common and general clinical assessment and clinical 
reflection is not well described and systemized. It 
requires time and experience. An important overall 
question is, whether the needs of the families are 
truly elucidated if in the future we are relying mainly 
on standardized testing? One can certainly worry that 
clinical reflections and diagnostic decisions 
increasingly become premature due to structural 
changes. The field of child and adolescent psychiatry 
in Denmark has in recent years been burdened by 
political decisions to increase efficiency, which in 
effect results in less time for the individual patient. 
This means there is less time for the general clinical 
assessment and for interdisciplinary reflection. To 
name one current issue, it is hardly meaningful from 
a professional perspective to have “fast track” 
diagnostic processes, as we know the 
symptomatology of children and adolescents can 
change significantly over a short time period. It may 
be more important to recognize the patient as a 
person – and consider the patient’s perspective – 
than to immediately decide upon a diagnosis. The 
diagnostic and treatment planning process is 
heterogeneous as different children with the same 
main diagnosis have different treatment needs. 
Further, the categorical nature of classical diagnostic 
classification is potentially excluding important 
information on the patient and the patient’s family. 
Hence, the diagnosis in itself does not constitute an 
adequate basis for individual treatment planning 
(1,2).  
The humble clinicians dare to give time (although 
nearly impossible) to be doubtful and discuss 
uncertainties with colleagues in an interdisciplinary 
field – all in order to consider information from 
multiple perspectives. They do not blindly trust in 
standardized testing, but consider their validity 
critically and in the context of supplementary 
information on the patient. However, one also has to 
recognize the sociological phenomena in humans 
that makes us pull away from uncertainty and 
complexity, and search for a solution to the current 
problem (3). Hence, what happens when time is of 
the essence? We think it may further result in moving 
away from diagnostic precision – and from the real 
issues of importance to the patient – when time 
becomes a limited luxury. 
Developmental psychopathology is a research field 
with particular focus on the processes that contribute 
or protect against the development of 
psychopathology. In order to capture the “specificity 
of the individual’s life” and guide decision making in 
planning treatment, “case formulation” has been 
suggested by several researchers (4). The method in 
detail will not be described here. However, in overall 
terms, it is a theory embracing diverse hypotheses 
and perspectives on why current difficulties have 
arisen. These hypotheses are considered in the 
context of the child’s developmental trajectory and 
include information on vulnerability and risk factors 
as well as protective factors. The idea is to allow the 
clinician in an interdisciplinary framework, to weigh, 
sort and summarize all information in a manner that 
makes sense for each family. This is a more 
systemized way of carrying out clinical assessment, 
which provides a basis for treatment planning that 
can be adjusted continuously when needed. The 
obvious strength of this mindset is that it provides a 
 151 
 
supporting framework to the process of comparing 
clinical data to empirical knowledge.  
In our opinion, today’s psychiatry is facing two 
problems: first of all we do not know the actual real 
worth of the “general clinical assessment” as a 
concept due to great variability in clinician experience 
and time spent. On the other hand, we do not know 
the consequences if this information – as part in the 
overall information gathering – is gradually excluded 
from the diagnostic process due to the well-known 
pressure of time and resources. What is the result if 
this development is in favor of standardized testing? 
To name one example, we know that the validity of 
the Autism Diagnostic Observation Schedule 
(ADOS) depends on the clinician’ experience (5). 
This puts the validity of at least some standardized 
measures into question. This may very well also be 
the case for clinical assessment and reflection. 
Hence, case formulation may prove to be an 
example of evidence-based “clinical practice”. 
However, despite the potential importance of case-
formulation in clinical practice, the method is still 
placed next and secondary (if considered at all) to the 
more classical diagnostic classification systems. 
There is a need for research focusing on how to 
improve the clinical practice through the use of case 
formulation methods. Three important aspects of 
evidence-based psychiatry include: 1) external 
evidence; 2) patient/family preference; and 3) 
clinician experience and clinical practice(6).

I. INTRODUCTION 
For the safety problem of the large sports venues, this 
paper introduces a multi-function alarm system based on the 
wireless communication system[1]. It can realize the stadium 
smoke or combustible gas, the infrared detection and the 
temperature alarm.  Through the sensor and the wireless 
communication module, the collected data was send to the 
user or the main control platform. The system includes the 
minimum system based on STC89C52, sensor circuit 
composed of the DS18B20, HC-SR501, MQ-2, GSM 
communication module and the LCD1602 display circuit. 
The software system includes the main program, the GSM 
SMS transceiver program, the display program and the 
temperature detection program[2]. 
II. OVERALL DESIGN OF THE SYSTEM  
A. The system function block  
The hardware system is composed by the smallest system 
of MCU, the GSM module, the display circuit, the buzzer 
control circuit and the sensor circuit[3]. The sensor circuit is 
composed of three parts: the smoke detection, the human 
infrared detection and the temperature detection. It is showed 
in Figure 1.

From Figure 1, when the three sensors detect the smoke, 
the human body or the high temperature, the alarm 
information is sent to the microcontroller. The 
microcontroller detects the alarm by judging the threshold of 
the buzzer circuit. Then the GSM module sends the alarm 
message to the user. 
B. The design of the minimum system 
The minimum system of single chip microcomputer is 
composed of single chip microcomputer, crystal oscillator 
circuit and reset circuit[4]. As shown in Figure 2.

The principle of reset circuit is to reset the program 
manually when pressing the button, reset the program, and

restart it. In the crystal oscillator circuit, X1 provides 
oscillating signal for the crystal oscillator to the 
microcontroller, and the MCU runs into the running program. 
C. Example Sensor detection circuit 
1) Temperature detection. 
The temperature of the environment is collected by 
DS18B20 and the collected information is sent to the circuit 
through the interface. The temperature range is -55 ℃ 
~+125℃. The increment is 0.5℃ and the temperature can be 
turned into a number. The MCU can read the temperature 
directly. This temperature sensor reduces the external circuit 
and makes it easier to realize[5]. 
The DS18B20 consists of four parts: the 64 bits ROM 
with the single-wire interface, the temperature sensor, the 
temperature trigger and the configuration register. Its 
structure is shown in Figure 3.

Figure 3. The internal block of DS18B20. 
Through the single bus protocol, the single chip 
microcontroller reads the data and operations from the 
DS18B20. Finally it is concluded the temperature value. The 
resistor in the circuit used for the pull-up, it has the ability of 
the anti-interference. 
2) Smoke and combustible gas detection. 
The MQ-2 smoke sensor is a kind of the air sensitive 
material with the tin oxide. It has the low conductivity in the 
clean air[6]. Therefore, in the surrounding environment, the 
conductivity of the sensor increases with the increase in the 
presence of the smoke or the combustible gas. 
LM393 is the operational amplifier which is used as a 
voltage comparator. When the input voltage V+ > V-, the 
output is high and the output is low when V- > V+. 
The MQ-2 is the smoke sensor. In MQ-2, R1 and RV2 
constitute the circuit. RV1 is a sliding resistor which adjusts 
the input voltage of LM393. In general, when V+ >V-, 
outputs the high level. When the MQ-2 detects the smoke or 
the combustible gas, its resistance decreases and the voltage 
is smaller, the V- voltage changed higher, so that the V+<V-. 
The LM393 outputs the low level, the light emitting diode 
conducts. The single chip microcomputer detects the low 
level, so as to start the alarm. 
The detection circuit of the smoke and combustible gas is 
shown in Figure 4:

3) Human infrared detection 
With the HC-SR501 module, the system detects the 
human body. When the human body passes through the 
infrared detection zone, the MCU outputs the trigger signal 
to the wireless module. When no one is unmanned, the MCU 
is used to detect the high level through the pull resistance[7].

HC-SR501 is the human body induction module. When it 
detects the human body, pin A1 outputs the high level. 
Through the current limiting resistor, Q1 turns on and the 
collector connects to the GND and then switched to the low 
level. At this time, the light emitting diode conducts and the 
LED lighting. The single chip microcomputer detects the low 
level and begins an alarm. In the circuit, the capacitance used 
as the filter, R2 is the pull-up resistor. When there is no 
person, the Q1 turns off. The single chip microcomputer can 
detect the high level by the pull-up resistor. 
III.  SOFTWARE SYSTEM DESIGN 
A. Main program design 
The software of this system is designed with a single chip 
system program as the main program, and the sensor module

Figure 6. Main program of the systemm. 
At first, the MCU initializes and then the temperature 
module, the human infrared module and the smoke alarm 
module are also initialized. If the system detects the smoke, 
sends the message to the mobile phone or determines 
whether the temperature exceeds the threshold value. If it 
exceeds it, send data to the user or judge the results of the 
human detected. If detects the human body sends the data to 
the mobile phone or not. 
B. GSM module program design 
The program design of this part is the design of serial 
communication of GSM[9]. First, port, baud rate, parity bit, 
data bit and so on are first set up, then the short message is 
sent by TC35 AT command. The flow of its program is 
shown in Figure 7.

switch command, if the #OPEN# is received, the control 
relay is closed, LED lights, if received the #CLOSE# 
command, control relay off, LED lamp. 
IV. TEST RESULT AND DATA ANALYSIS 
When the system detects the data exceeds the threshold, 
the GSM module begin works. It send SMS to the user or the 
main platform, which could transmit the data in time. In 
order to display the test results, uses the screen results of the 
mobile phone in Figure 8.

command is send, the LED turns on. When sending 
“CLOSE” command the LED turns off. It proved the GSM 
module could receive short message successfully. The test 
result is shown in Figure 9.

V. CONCLUSIONS 
In this paper, the multi-function alarm system could 
detect the smoke or combustible gas, the infrared 
identification and the temperature by the multi-point sensor 
in the large stadium. The collected data transmitted by the 
mobile communication to the mobile phone or the main 
platform. The system is simple and cheap, it has various 
functions for the monitoring system conveniently.

Abstract—This This article presents a quick way to develop 
your system with custom components in Delphi. Use the above 
method can minimize code duplication, improve work 
efficiency. In this paper, we apply this method to the 
development of information management system in a 
university based on the Data Snap three-tier architecture. 
Through practice, we find that the workload of the original 
three months, and we only need 20 days to complete. Therefore, 
adopting the rapid software development method based on 
component design proposed in this paper can not only shorten 
the programming time of management systems such as ERP 
and information management by more than two thirds, but 
also bring great advantages in system development.

I. INTRODUCTION 
With the advent of the information age, we are more and 
more inseparable from technology. Now developed a lot of 
PC software such as information management systems that 
can help people save a lot of manpower, material resources. 
Especially every year at the end of annual work statistics, the 
design of a set of software through the relevant settings for 
automatic statistical calculation, approval, access and other 
functions is necessary. The completion of the software can 
be fully realized at any time computer statistics automatically 
calculate the workload of a variety of teaching and research, 
but also can effectively avoid errors in the calculation 
process. 
There are a lot of software that uses a lot of languages to 
develop the PC end now, but to the visual software 
development, this text uses Delphi to finish. And Delphi is a 
powerful, Windows-based environment, object-oriented 
visual application development tool. It combines the power 
of the traditional programming language Object Pascal with 
the database language for both traditional arithmetic 
programming and database programming. The Data Snap 
technology system in Delphi provides a mechanism for 
transferring database information between the client and the 
application server. Meanwhile, the rich component library 
brings great convenience to the program design. Delphi has 
become one of the most popular visual software 
development tools today. 
When we used Delphi to develop PC software, we 
developed a way to customize the components to complete 
the software development and make the program completed 
in three months and we only need 20 days to complete. 
II. THEORETICAL BASIS 
A. Practicality of Custom Components 
In a system development, design a custom component. In 
the process of system development can be based on the 
analysis of needs sorted out the same part of the logic 
function, the use of custom components to complete the 
corresponding function. Therefore, anytime, anywhere 
custom components into different needs of the interface 
according to the corresponding function, reduce code 
duplication and greatly facilitate the development of 
programming speed. 
In an ERP system to do needs analysis, we will find a lot 
of repetitive logic requirements, For example: doing 
computer college information management system, whether 
it is to deal with college business or teachers related to the 
operation, there are for the basic data to add, modify, delete 
and so on. That by designing custom components: Add 
button to complete the corresponding function, into the page 
you need to complete its specific functions and greatly 
reduce the programmer's efficiency. 
B. Inheritance of  Custom Components 
DElphi component is an object library, but also a class. 
The base class for all objects in Delphi is TObject, and the 
most primitive base class for a component is TObject, as 
shown in Figure 1. 
2018 International Conference on Sensor Network and Computer Engineering (ICSNCE 2018)

Tobject
Exception TInterfacedOBject TStream TPersistent TComObject
TgraphicObjtce TGraphic TComponent TCollection TStrings
TApplication TDataSet TMenu TControl TCommonDialog TField
 
Figure 1.  Example of a ONE-COLUMN figure caption. 
The hierarchy of components in this structure is: TObject 
----> TPersistent -----> TComponent -----> TControl. 
TComponent, the base class for all Delphi components, 
inherits from this class for all object libraries that you want 
to register directly with the IDE for visualization. 
TComponent provides the necessary information to make the 
component work on Delphi's IDE. Then TComponent 
derives the TControl class, which is the base class for all 
flagship visual controls. All of our components are based on 
TComponent. 
III. EXPERIMENT AND TEST 
A. The Basis for Custom Component Development 
In the development of custom components we need to 
analyze a page needs and then do some work: 
 Data acquistion: In general, we are all custom 
components that design functionality, and we need to 
get the data or output the data. In each page there 
will be a lot of data-type components, how do we 
find the corresponding data components, you can 
design components by the naming rules to find the 
corresponding data-type components. For example: 
Set the settings in the component, to the components 
of a unified naming rules such as: 
cktext1_XXXX,XXXX for the database table field 
names, according to cktext1 can find the components 
needed, according to the XXXX components and 
database fields correspond. 
 Data transfer: Passing data using JSON. JSON is a 
lightweight data exchange format based on a subset 
of ECMAScript that stores and represents data in a 
completely independent of the programming 
language. There are only two structures in JSON: 
Objects and Arrays JSON values consist of numbers, 
strings, logical values, arrays, objects, null, and so 
on. Using JSON as a data exchange format between 
the client and the server, the JSON data format can 
be used directly by the server, greatly simplifying 
the code development of the client and server, and 
easier to maintain. And the data format is relatively 
simple, easy to read and write, the format is 
compressed, occupy a small bandwidth. 
 Mutual exclusion between functional components: 
When the button On Click is executed, in order to 
avoid data confusion, you must make the button is 
not related to the button is invalid. For example, 
when you click the Add button in the information 
management system, the buttons, such as modify, 
delete, archive, data export, return, etc., must be 
inactive. The Save and Cancel buttons must be valid. 
2 When the save or cancel button is clicked, buttons 
such as add, edit, archive and return should be valid, 
while save and cancel buttons should be inactive. 
Therefore, the entire information management 
system interface point of view, in addition to 
archiving, data printing, return no mutual exclusion, 
the other buttons need to be mutually exclusive with 
other buttons. 
B. Associations Between Components in the Page 
There are many custom components in a page, but we 
need to know the current step to the program flow, the 
current table, the current operator, the current name from the 
table, and others. Then we need to design a custom template 
components on each page, template components design 
attributes as shown in Table 1: 
TABLE I.  TEMPLATE ATTRIBUTES

C. Implementation of custom component development 
After the preparation of the above two parts, the process 
of custom components in Delphi contains the following steps: 
 Create a library unit that contains new parts. 
 Member has inherited a new type of component type. 
 Add properties, methods and events. 
 Register parts with Delphi. 
 Create Help files for the component's properties 
methods and events. 
Custom components such as adding components The 
main code is as follows: 
Uses System. SysUtils, System. Classes, Vcl. Controls, 
Vcl. StdCtrls, Vcl. Buttons, Vcl. ComCtrls , 
DBGridEh, Math, Datasnap. DBClient, mysave, 
IniBoxes, mygd2wgd, MyIniDB ComboBox, MB, MyIni

ComboBox, Vcl. Graphics ;//  The required unit file for 
creating the component. 
RegisterComponents('d102', [Tmyadd]); 
constructor Tmyadd.Create(AOwner:TComponent); 
inherited; 
self.OnClick:=myadd; 
nowday:=FormatDateTime('yyyyMMddhhnnss',Now()); 
czsj:=nowday; 
ss1:=inttostr(i); 
lcbh:=czsj+ss1;  
(self.Owner.FindComponent('MB1') as 
TMB).mb_lcbh:=lcbh; 
lcmc:=(self.Owner.FindComponent('MB1') as 
TMB).mb_lcmc; 
czr:=(self.Owner.FindComponent('MB1') as 
TMB).mb_czr; //Obtain name and operator letter via 
template component 
 k:= Owner.ComponentCount; //Get the number of 
components on the form 
for j := 0 to k - 1  do 
Begin 
 namey:=Owner.Components[j].ClassName;  
if(namey='Tmyedit')then(self.Owner.Components[j] as 
TBitBtn).Enabled:=False//Button exclusive event  
 else if(namey='Tmysave')thenif(namey='Tmysave')then  
begin 
(self.Owner.Components[j] as TBitBtn).Enabled:=True ; 
(self.Owner.Components[j] as Tmysave).isadd:=True; 
End 
//Other mutually exclusive operation 
(self.Owner.FindComponent('maindbgrid') as 
TDBGridEh).Enabled:=False; 
  main_dataset:= (self.Owner.FindComponent('main_set') 
as TClientDataSet); 
main_dataset.Append;//Find the form on the main 
interface with the data after the Query, and add records 
 main_dataset.FindField('lcbh').AsString:=lcbh; //New 
process ID 
main_dataset.FindField('czr').AsString:=czr; 
main_dataset.FindField('czsj').AsString:=czsj; 
main_dataset.FindField('lcjdmc').AsString:=lcjdmc;

management system model was initially realized, the 
idea of software reuse was realized, the phenomenon 
of repeated encoding was reduced, and the software 
development efficiency, maintainability and 
scalability were improved. 
 The use of custom components in the information 
management system and the related operation of 
each page through the related parameter settings are 
feasible and safe.

Abstract—In this paper authors introduced the overall design 
of learning resource sharing platform in the pure IPv6 
environment, including the client and the web server and the 
back-end database, and the user management, the detailed 
design of the three aspects of resource management platform 
and administrator management. Finally authors introduced 
application of decision tree in this website.  
Keywords-IPV6; Address Binding; Decision Tree 
I. INTRODUCTION 
With the development of computer technology, people's 
work style, lifestyle changes, the increasing demand for 
computer networks, and the rapid increase in the number of 
Internet users, making the urgent increase in IPv4 address 
requirements. The existing ipv4 address has long been 
unable to meet the demand. After the depletion of IPv4 
address in Asian, Latin America, Europe and the United 
States and other regions , on September 24, 2015, North 
America also declared IPv4 address were exhausted, leaving 
only a small amount of the African region [1]. In order to 
maintain the use of ipv4 addresses, there are technologies 
such as NAT[2] (network address translation) technology, 
VLSM (variable long subnet mask) technology[3], CIDR[4] 
(no class interdomain routing) which can not solve the 
fundamental problem of IPv4 address depletion. So the 
technology translates from IPv4 to IPv6 and IPV6 
environment in a variety of applications have been carried 
out in the world research, Japan and other countries in the 
study of IPV6 new technology has been at the forefront of 
the world. 
IPv6 address is 128 bits, which can represent the great 
address space, good scalability, better quality of service 
(Qos), security、  mobility and improve the efficiency of 
routing and other characteristics [5]. China has started the 
next generation of Internet Demonstration Project (CNGI) 
project in 2003, one of the countries with relatively advanced 
global start and multiple IPv6 addresses, but the use of IPv6 
addresses is far behind, The conversion of IPV4 and IPV6 
uses three techniques, namely, dual-station protocol 
technology[6], tunneling technology[7][8] and translation 
technology (also called protocol conversion technology)[9]. 
At present, the most widely used technology is dual station 
technology. 
In this paper, IPV6[10][11] itself is inherently safe, the 
address is unique, the address is wide and the transmission 
speed is fast. In the pure IPV6 environment, it is proposed to 
develop the campus learning resource sharing platform based 
on ipv6, which can realize the upload of various learning 
resources Download, in order to achieve the real learning 
resources to share, as a common progress, learn from each 
other, to discuss each other, so as to improve the quality of 
teaching, improve teaching effectiveness. 
II. THE OVERALL DESIGN OF LEARNING RESOURCE 
SHARING PLATFORM 
A. Overall design  
The learning resource sharing platform is divided into 
two modules: client and server, As shown in figure 1. 
 
 
Figure 1. Overall design 
2018 International Conference on Sensor Network and Computer Engineering (ICSNCE 2018) 
55 
 
The learning resource sharing platform[12] is divided 
into two types of users: learners and administrators, learners 
upload and download and browse learning resources, 
communicating with each other through the message board; 
administrators of learning materials and message content 
audit, management[13]. The general function of the system 
for the user is to upload learning materials and the 
corresponding description of the data, after the review by 
other users can download the use of the user after the use of 
the data can be evaluated, feedback to the platform of the 
message board. 
All users who have registered in this platform can upload 
and download student resources. Before uploading, you need 
to verify the IPv6 address and user identity. The uploaded 
resources need to be audited before being downloaded. 
Resources need to be feedback and evaluation after 
downloading resources. The development of the above 
platform is and the use of pure ipv6 environment is carried 
out. 
B. Detailed Design 
1) User Management 
a) User registration and login 
Users can register through the registration web page on 
the platform to become a user member of the platform. In 
this case, the user's IP address should be obtained and bound 
with its account. After success of the registration, the user 
can login through the login web page on the platform. After 
logging in, you can upload, download, play online and 
message and other operations. Unregistered or unregistered 
users can browse the resources on this platform, but they 
can’t do the above operations. They can only use it before 
logging in.  
b) Account management 
Users can use the personal information web page to view 
the current user's registration information. In the meanwhile, 
we can update the user's property or modify the password 
through the web page. Of course, for the user who forget the 
password, they can log in the web page to find the password 
to jump to modify the page to modify. When the login 
account is different form the last login ipv6 address, we can 
determine whether the new ipv6 the address is the same to 
the old. If it is, we allowed to continue to log in; if not in the 
same network account, prompts him to answer questions, the 
answer is correct, allowing it to continue to visit; otherwise, 
continue to answer questions, three times to prevent access to 
this Law to prevent non-I upload illegal information, or to 
prevent non-I am injected into the illegal operation of virus 
files to protect the safety of users and resources. 
C. Resource management 
The platform is a resource sharing platform which needs 
to cover all aspects of teaching resources. The platform in 
accordance with the discipline of resources classification, 
and real-time update resources. The main functions of it are: 
upload, download, online, message and so on. 
1) Resource upload and download 
Users can upload the various forms of resources, whose 
types are not limited. For example, you can upload Word 
documents, PPT courseware, Flash animation and video 
resources. The suffix of the resource can be. 
Doc, .ppt, .zip, .rar, .swf and .TIF and so on. Only the 
resource information of the resource file is stored in the 
database. The website provides the resource download 
service according to the resource path. The uploaded 
resource file is usually stored in a subdirectory under the root 
directory of the website. Users can only release resources 
after log in. Users can fill out the information of the resource 
name, detailed information and other information. When 
users publish resources to determine whether the user's IPv6 
address and the registration of the IPv6 address in the same 
network, if the same network, the user can upload data, if not 
in the same network, you need to answer specific questions 
to ensure the safety and reliability of users and resources. 
Users can download the various forms of resources on 
the platform, each resource below the corresponding 
download. After the user clicks the download button, the 
download box will pop up, the path will be selected to click 
to start the download, and the user can select the default 
download path. After the completion of access to the 
appropriate path to view resources. 
2) Resources online browsing 
Users can browse some of the resources in the system, 
that is, you can browse the resources online without 
downloading. Users simply click on the play button below 
the resource, you can browse online. For users who do not 
have the button to play, the user can only download and 
browse. 
3) Message module 
The user can comment on a resource, they can also reply 
to the resources of other users to ask questions, in order to 
achieve the purpose of interactive learning; users can delete 
their own message, the administrator can delete the message, 
the message can not be edited. 
D. Administrator management 
Administrators can view, upload, download, delete 
resources, they can set the upload resource size limit, for the 
user to upload the resources for review, pending approval 
before the resource can be used. At the same time the 
administrator can also view, send and delete messages. 
Of course, as with the user to upload resources, the 
administrator login after the implementation of 
administrative authority before the need for IPv6 
authentication to determine the administrator's IPv6 address 
and the registration of the IPv6 address is the same network 
segment. If they are in same network segment, the 
management administrator can perform administrative 
privileges, and if it is no longer in the same network segment, 
the administrator needs to answer specific questions to 
perform administrative privileges. Thus ensuring that the 
administrator himself is in operation to prevent others from 
maliciously executing administrator privileges. To ensure the 
safety of system operation.

III. SECURITY MEASURES FOR LEARNING RESOURCE 
SHARING PLATFORM OF IPV6 
A. The characteristics of IPv6 ensure the safety of network 
resources 
Because IPv4 is just a simple network interworking 
protocol, a large number of security issues are not considered 
in, and IPv6 achieves IP-level security. Ipsec is a series of 
security protocols that define the security services used at the 
Internet layer. Features of it includes data encryption, access 
control to network elements, data source address verification, 
data integrity checking, and replay prevention.IPv6 includes 
IPSec protocol, which can protect users from some network 
attacks[14]. 
B. A huge resource of IPv6 addresses makes it possible to 
determine the one-to-one relationship between users and 
addresses 
Since an IPv6 address is 128 bits, theoretically there are 2 
^ 128 different IPv6 addresses. So basically it is guaranteed 
that everyone has a unique IPv6 address. This guarantees a 
true one-to-one correspondence between the user and the IP 
address. IPv6 does not support subnet masks. It only 
supports subnet prefix identification. The IPv6 prefix uses an 
address prefix similar to the CIDR mechanism in IPv4 
addresses. IPv6 uses address prefixes to identify networks, 
subnets, and routes. The IPv6 address is divided into two 
parts: the subnet prefix and the interface identifier [15]. 
C. IPv6 address and user information binding 
One-to-one relationship between users and addresses 
ensure each user has a unique IPv6 address. This makes it 
possible to bind ip addresses to user information. The 
purpose of binding user information and user IP address is 
when you login next time, we can determine whether the 
same person in operation. If the user login address is same as 
the last ip address, then at least we can ensure the user or 
authorized others are operating. If it is not my own 
operations, then we can confirm whether it is himself by 
asking questions, if the answer is incorrect, only allow users 
to browse, but not allow other upload or download or leave a 
message and other operations. Thus the system ensure the 
security of user information, but also protect the network 
resources and management of the security. 
D. Application of Decision Tree Algorithm in Security 
Assurance 
When the user register, we will get the user's IPv6 
address and bind the user's information to their IPv6 address. 
When the user login again, we first determine whether the 
user's IPv6 address and the IPv6 address bound to it are in a 
campus network. If the user is in the same campus network, 
we use method1. The user can directly upload data, 
download resources, learn online, message interaction and 
other operations. If not in the same campus network to 
determine whether in a city. If they are in a city, then we use 
the method2, the user needs to enter the verification code, the 
verification code is correct, continue to use method1.If  they 
are not in a city , we determine whether it is the national 
address, if  it is from other domestic cities ipv6 address, then 
we use the method3, the user answered specific questions, if 
the problem is correct he can continue to access, we use 
method 1, or only have the right to browse or directly denied 
access to this site. This to ensure the safety of users, the 
safety of learning resources and management of the safety 
and reliability, this  to ensure the safety of the entire learning 
resources platform. We analyzed ipv6 address in the 
experiment and divided into four categories in Table 1 below, 
and four kinds of ipv6 addresses for different treatment. In 
this process, if the ipv6 address is wrong ,the website will 
direct denial of access after prompt error. In general, there 
will not be wrong ipv6 address, ipv6 address in the ipv6 
library are automatically obtained by the system.

Therefore, we firstly classified ipv6 address based on the 
address of the library. Of course, for each user ipv6 library, 
the ipv6 address is not the first time that the address of the 
application, but each time you use the address of these four 
categories ways to accumulate statistics, what kind of login 
the most frequently used, the data in the ipv6 library will be 
updated to the most frequently used ipv6 address. Based on 
the classification process, the decision tree [16] is used to 
make the classification decision. The decision tree is as 
follows:

IV. CONCLUSION 
The resources provided by the website include images, 
text, video and other types, the content is not limited to the 
2018 International Conference on Sensor Network and Computer Engineering (ICSNCE 2018)

school curriculum knowledge. Rich and comprehensive 
learning resources for students to provide class and 
extracurricular learning opportunities. Based on the 
realization of ipv6 makes the site security, user and resource 
security has greatly improved. The speed of access and 
download makes it unnecessary to wait for too long. The 
binding of IPv6 address and user information makes the user 
upload the resource reliability to ensure the security of the 
user, the security of the learning resource and the security of 
the management And reliability, thus ensuring the safety of 
the entire learning resource platform. The resources of the 
learning resource sharing platform and user and information 
reliability determine the utilization of the platform, is a major 
supplement to school teaching, improve the quality of 
teaching and teaching results.
