I. Introduction
In daily operations, power companies need to make full use of advanced information processing technology. In production management, assist in analyzing the operation status of equipment, predicting accident equipment, reducing equipment failures, and quickly analyzing faulty equipment and providing emergency immediately. The solution is to improve the rapid response capability of functional departments, shorten the power outage time, improve the reliability of power supply, improve the customer service level of the power supply bureau, increase the sales of electricity in daily operation management, understand the operation mode of the transmission and distribution network, and avoid misuse. In addition, from the information technology itself, information sharing and collaborative work in the whole enterprise, reducing data redundancy, thereby reducing data maintenance costs, GIS technology is one of the effective means. The dispatching and electrician area of ​​the power company often needs to go to the site for daily work, such as daily patrol work, emergency repair work, etc., and need to check the facility information on site. The former staff carried a large number of drawings to the site. The disadvantage is the drawings. The query speed is slow, the drawing update cannot be kept up, and the drawing accuracy is not high. At the same time, due to the lack of effective supervision means, it is not easy to ensure that the inspection work is completed on time and in good quality (if there is any missed inspection, it is not patrolled according to the prescribed time).
The mobile inspection system extends the original information system to the work site, and achieves the purpose of obtaining the information needed for the work at any time and any place, and solves the need for on-site staff to query a large number of accurate drawings. The patrol handheld is equipped with GPS (Global Positioning System), which can be used to record the route of the positioning operation by satellite positioning. This brings another role to strengthen the responsibility of the specific staff and solve the original lack of means to assess the staff. Whether to check the power line and other issues in time according to the route. The business operations of the system adopt a procedure mode to truly realize the standardization and informationization of the business. The business management functions provided by the system can integrate the work of the field staff with the business information management system within the enterprise. The implementation of this system can really improve work efficiency and improve work accuracy.
Second, the system design
The mobile inspection system is divided into two parts: the client and the server. The client is installed on the handheld and the server is installed on the PC.
(1) Functional description
1, client function
1) Query device attributes: The user can query the detailed attributes of the device according to the line name and the tower number.
2) Confirm user identity: The user needs to enter the login password to confirm the identity of the user.
3) Download the user inspection task: download the user inspection task and related data from the server according to the login identity of the user login system.
4) Provide equipment optional defect code: According to the different equipment of the current inspection, the corresponding common defect code is given. The user only needs to select the code, and the corresponding defect can be recorded in the database.
5) Handwritten record defects: For special defects, the system provides a method of handwritten recording as an auxiliary means.
6) In place supervision: Using the global positioning system, it is possible to reliably confirm whether the user is in place.
7) Configuration Management: Provide administrators with a management system entry. For example, update user data, add new device data, and so on.
2, server-side functions
The server is mainly used to connect with the database, manage data, modify passwords, and complete data upload/download between the server and the PDA. It can satisfy the query and analysis of the data of the patrol service by any computer installed on the LAN. .
1) Management of the inspection line: Formulate the inspection plan, formulate corresponding inspection plans for different users, and generate corresponding equipment data.
2) Write back the completion of the patrol task: upload the user's inspection results to the server database.
3) Supervision and statistics in place: According to the coordinates of the tower and the coordinates of the tour, the inspection time, the statistical inspection is in place.
4) Defect Management: Check the defect status of the line. Including new defect records, defect defects.
5) Data download: According to different line patrol personnel, download the data of the line inspection plan and the line, tower property and defect information related to this plan to the PDA.
6) Data upload: upload the data on the PDA to the server, including the completion of the line, the defect, the GPS path, and so on.

(3) Operation control
1, server-side operation control
1) Inspection business management, patrol business management mainly includes the formulation, approval, inspection summary, defect record, etc. of the inspection line plan.
This function is used to manage the daily inspection of the line. First, the team will develop a line inspection plan, and then submit it to the director for approval. After the approval is passed, the data can be downloaded to the PDA, the inspection line plan is executed, and the inspection results and defects are uploaded from the PDA to the server. Strictly abide by the provisions of the "Operation Procedures for Overhead Transmission Lines" and "Electricity Safety Work Regulations", do a good job of inspections, fill in relevant business forms in accordance with the inspection process, and prepare for accident prevention. The design idea of ​​operation and maintenance is embodied in the patrol management module. The patrol management module includes various patrols such as periodic patrols, seasonal patrols, special weather patrols, faulty patrols, night patrols, supervised patrols, patrols due to equipment modifications or other conditions, and these records and data are combined. Business management.
a. Patrol plan
After the team members enter the inspection plan and summary window in the inspection management module, the monthly inspection plan can be made according to the situation. When it is determined that it needs to be submitted to the work area director for approval, click the submit approval button, select the approver, and click The OK button saves the established inspection plan in the inspection plan and summary table, and submits the planned inspection plan to the selected approver for approval. The approver can approve the inspection plan waiting for approval in the approval management window. After the approval is passed, the patrol personnel can conduct inspections according to the inspection plan.
b. Patrol summary and defect record
After the patrol personnel completes the line inspection, the patrol results on the PDA are uploaded to the server. The patrol results include defects or problems found during the patrol process, guard line publicity records, patrol records, and defects eliminated during the patrol. Defects found during the inspection process are stored in the equipment defect table. The maintenance line records are kept in the inspection plan and summary table. According to the defect records eliminated in the inspection, the defect records are updated and the defect records are set to Has been eliminated.
c. Entry window
The entry window for the line plan and summary is as follows:
2) Data transmission management, the data transmission module is mainly used to initialize the PDA data, or download the data to the PDA, or upload the data on the PDA to the server.
a. Initialization
The PDA that was changed for the first time or the initialization data in the database needs to be re-initialized. The purpose of the initialization is to download some data that does not need to be changed frequently to the PDA at one time, so as to reduce the time required to download the data normally, which is mainly the data of the code table.
b. Data download
According to the selected line patrol personnel, download the line inspection plan to the PDA, and download the equipment attributes of the patrol line and the defects that have not been eliminated to the PDA, so that the line patrol personnel can query during the field operation.
c. Data upload
Upload the patrol data on the PDA to the server. These data mainly include patrol records, newly discovered defects, original defect elimination, GPS data, and so on.
3) Client operation control
