Abstract: According to the management requirements of a large number of spatial data and attribute data generated by daily 

inspection of power system, the power inspection information management system is developed by using WebGIS (Web 

Geographic Information System) technology. Firstly, the user layer of the whole system is developed by using HTML and CSS 

as tools, and then the basic data is managed by using sky map API and JavaScript as tools, combined with the relevant functions 

of sky map API, the functional modules of the system are developed to realize the functions of visual information management 

and two-way query. The system can provide corresponding solutions for the management of Power Patrol information. 

Keywords: MapWorld; WebGIS; Power Inspection; Information System. 

 

1. Introduction 

Electric power system is the core infrastructure of national 

economic construction and residents' life. In order to ensure 

the safe and stable operation of electric power system, strict 

daily inspection is required. In the daily patrol inspection 

process of power system, the patrol objects involved, such as 

lines, stations, transformer stations, etc., are spatially 

presented in the form of points, lines, planes, etc. At the same 

time, a large amount of attribute information is generated in 

the patrol inspection process. Scientific and effective 

management of these patrol objects and patrol information is 

the basis for giving play to the patrol inspection effect and 

ensuring the safe operation of the power grid. According to 

the characteristics of patrol objects and patrol information, 

which have both spatial location information and attribute 

information, an effective way to manage such information is 

to run Geographic Information System (GIS) technology. 

This paper uses this technology to design and develop a set of 

electric power patrol information management system. 

2. MapWorld API 

When Geographic Information System technology 

manages information, it will run in a unified data management 

mode and data operation mode according to the 

characteristics of spatial information and attribute 

information, which can play a standardized effect. In order to 

better use these unified management and operation modes, 

developers integrate these modes into a set of standard 

instructions, which are called API (Application Program 

Interface), The secondary developers only need to call the 

corresponding functions to complete the corresponding 

standardized operations, which greatly reduces the 

development workload and reduces the possibility of program 

running errors. The MapWorld API is a map API platform 

established by the National Basic Geographic Information 

Center. It mainly provides two functions, one is to provide 

vector map data including conventional ground objects, 

which omits the process of re mapping basic ground object 

vector data by secondary developers; Second, it provides 

function call interfaces including common functions such as 

map operation, object search, and object creation, which 

greatly simplifies the development workload of secondary 

developers. This paper uses the MapWorld API as a tool to 

make use of these two functions to better achieve the design 

goal. 

3. Overall Design of System 

The overall design of the system is to design the overall 

structure of the system at the macro level, which is the basis 

for the development and implementation of the software 

system. The quality of the overall design determines the 

operation quality of the software throughout its life cycle, and 

is the basic guidance for the development work. 

3.1. User Requirements analysis 

According to the early investigation, the users of the 

electric power networks inspection information management 

system developed in this paper need to specifically include 

the following: 

3.1.1. Informatization operation of on-site patrol 

inspection 

The most basic and main function of the electric power 

networks inspection information management system is to 

realize the whole process information operation of on-site 

inspection. It is subdivided into operator identity login 

management, automatic transfer of inspection items, and 

image and text data entry of inspection results. 

3.1.2. Wireless upload of inspection data 

On site patrol inspection uses smart phones to collect 

inspection result data. After data entry, it needs to be 

synchronously uploaded to the data center of the system 

wirelessly. 

3.1.3. Unified management of inspection data 

The data uploaded from the mobile terminal or its multi 

system data terminal, after entering the management center, it 

needs to be managed uniformly in the management center.

Therefore, a function module for unified data management 

needs to be designed. 

3.2. Structure Design of System 

The software system developed in this paper runs in 

network mode and adopts B/S architecture. The overall 

structure of the system is shown in Figure 1. 

 
Figure 1. Overall Structure of System 

The system is generally composed of front-end (B end, 

browser end) and back-end (S end, server end). The front end 

runs on the mobile device of the operator, mainly used to 

complete the collection and entry of the electric power patrol 

inspection, and upload the entered information to the server. 

The back end is mainly composed of two layers, namely the 

business layer and the data layer. The data layer mainly 

completes the centralized storage and management of data, 

connects with the business layer through the data engine 

interface, provides data to the business layer, and receives the 

processed data from the business layer. The business layer 

undertakes the main business processing tasks of the entire 

system, which is composed of different functional modules. 

4. Calling of MapWorld API  

The map foundation of the system is realized by calling the 

MapWorld API, which is referenced in the header file of the 

web page file on the server side. The main code is as follows:    

<script type="text/javascript" 

src="http://api.tianditu.gov.cn/api?v=4.0&tk=Key"></script> 

    <script> 

        var map; 

        var zoom = 12; 

        function onLoad() { 

            map = new T.Map('mapDiv'); 

            map.centerAndZoom(new T.LngLat(117.41, 

36.89), zoom); 

        } 

    </script> 

After calling the MapWorld API, we can obtain the basic 

map data and complete the basic data settings of patrol 

information map visualization. 

5. Function Design of System 

The functional design of the system is to complete the 

design of each functional module planned in the overall 

design, so that each functional module can complete the 

corresponding work. The main functional modules of the 

system designed in this paper include: user information 

management, data browsing, data management, information 

query. The function module of system can be expressed by 

Figure2. 

 
Figure 2. Function module of system 

5.1. User Information management 

The user information management module is a functional 

module that stores and manages the user name, user 

information and login password. Its design idea is to establish 

a user information table in the system database. When a user 

logs in, the user name and password entered match the preset 

information in the user information table. If the information 

matches, the user is allowed to log in. If the information does 

not match, the user is refused to log in. This module not only 

classifies users' identities to provide different functions, but 

also guarantees system security. 

5.2. Field inspection module 

The field inspection module runs on the mobile terminal, 

and its main function is to provide the patrol inspectors with 

operation tools. After logging in, the patrol inspectors can see 

various inspection items, provide the security inspectors with 

input windows, and provide the function of taking photos, so 

that the security personnel can take photos of the site situation. 

After the patrol inspectors complete the inspection data entry 

and taking photos, the module stores relevant information. 

5.3. Data transmission and warehousing 

module 

The function of the data transmission and warehousing 

module is to transmit the inspection result information of the 

mobile terminal to the server and store it in the data table of 

the server. Here, we mainly use Java under the Android 

platform environment to develop the data transmission 

function, and use PHP to develop a receiving function on the 

server side to place the information in a separate table. After 

the data processing module verifies the data, it will be stored 

in the system database. 

5.4. Data processing and filing module 

The data processing and filing module runs on the server 

side and is mainly developed by PHP. The function of this 

module is first to verify the data transmitted from the mobile 

terminal. When the data is correct, the module stores the data 

in the information table corresponding to the project in the 

database and archives the data according to the time and other 

parameters of the inspection task.

5.5. Information browsing and query module 

The information browsing and query module also runs on 

the server side. Its function is to provide information services 

for users by using attribute data and spatial data 

interconnection based on archived patrol data. There are two 

forms of query service. One is to query the figure objects 

according to the attribute data, and the other is to directly 

query the attributes of the figure objects. 

6. Conclusions 

Electric power inspection is a basic and important work in 

the electric power industry. The data generated by the 

inspection is a direct reflection of the operation situation of 

the power system, which has great research and application 

value. How to manage and use these data is an important work 

to better play the role of electric power inspection. The 

comprehensive management ability of spatial data and 

attribute data provided by GIS technology, as well as the 

excellent performance of spatial analysis, can well realize the 

management, analysis and use of patrol information. At the 

same time, with the development of artificial intelligence and 

big data technology, as well as the introduction and use in this 

system, the analysis ability of the system will be further 

improved, and the value of electric power patrol data will be 

better excavated, which is the next development direction of 

this system.
