The PDA mobile device intelligent inspection system is an intelligent system that improves the level of equipment maintenance by ensuring the quality of the inspection work and improving the efficiency of the inspection work. The PDA mobile device intelligent inspection system combines RFID technology to mainly solve the equipment inspection There are three important issues in the work: 1. Inadequate inspections, missed inspections, or not on time; 2. Manually filling in inspection results is inefficient, prone to omissions or errors; 3. It is difficult for managers to understand in a timely, accurate and comprehensive manner The line condition makes it difficult to formulate the best maintenance and repair plan. The power equipment inspection system is a basic work to effectively ensure the safety of power equipment, improve the reliability of power equipment, and ensure the minimum failure rate of power equipment. At present, manual inspections and manual paper media recording are commonly used in China. These methods have many defects such as many human factors, high management costs, inability to supervise the work of inspection personnel, and low degree of informationization of inspection secretaries.
How to effectively improve the quality of inspection work? How to effectively informationize the inspection data? How to eliminate potential safety hazards during inspection work? These problems have plagued the inspection department for many years, and many attempts have been made, such as the use of bar codes, IC cards, and information buttons to monitor the work of inspectors.
The introduction of the power equipment handheld terminal inspection system has completely changed many problems in the inspection work, which are mainly reflected in the following aspects:
1. There is no need to install any equipment on inspection equipment and power equipment, which greatly reduces the cost of system procurement and maintenance.
2. Effectively ensure the inspection quality of inspection personnel, improve the safety and reliability of equipment and electrical equipment, and eliminate potential safety hazards.
3. Adopt wireless network and RFID technology to realize the information management of power equipment inspection work.
According to the actual needs and characteristics of the inspection work, the power equipment handheld terminal inspection system has functions such as route arrangement, data recording, work status supervision, data summary report, etc., and can be seamlessly connected with the existing information system of the power equipment enterprise, effectively Understand and check the working status of the patrol inspection, find the defects of the equipment in the shop in time, improve the safety of power equipment, power equipment and equipment, reduce production and operation costs, improve work efficiency, low cost, light and easy operation, and long equipment use time And other significant advantages.
After many on-site experiments, practice has proved that the system can effectively reduce the problems of missed and wrong detection caused by human factors. Thanks to the adoption of this system, the power equipment maintenance department has realized paperless data collection for the first time in the inspection work. At the same time, the equipment and power equipment management department can effectively supervise the work of the inspection personnel and realize the electronic inspection work. , Informatization, and intelligence, so as to maximize work efficiency, ensure the safe operation of power equipment and power equipment with a low failure rate, and promote the first-class work of science and technology in power equipment companies.
System construction goals
This line inspection system will achieve the following goals:
1. Realize the real-time and scientific management of power equipment inspection and management, and improve the level of maintenance and management and work efficiency.
2. Transmit the inspection data and RFID data to the inspection management department in real time by using the GPRS network.
3. Through the summary and analysis of the inspection system data, the hidden troubles in the power equipment circuit can be discovered in time.
4. Scientific management and arrangement of inspections by inspection personnel.
5. Provide a scientific and effective means for inspection, maintenance and management.
Personnel inspection process
When the inspectors are out for inspection, they can send a message to the center automatically (every 2 minutes, the interval can be set) or manually through the handheld terminal inspection device, reporting the current inspector’s location, time and other information, if found If a fault occurs, the fault type, device number and current handheld device terminal RFID information are sent to the monitoring center.
The monitoring center receiver receives the reported information and stores it. The system reads the information received by the receiver through the system, breaks down the time, location, equipment type, and discoverer of the fault, and automatically stores these data information in the database server and publishes it on the Internet at the same time.
The monitoring terminal uses the RFID system to display the inspection status in real time on the software, such as displaying the fault points found by each inspector, the emergency situation of various faults, the processing situation, the current status, and the location of each inspector at a certain moment. Inspection route.
The poles are affixed with RFID tags, and through a globally unique identifier, the inspectors must go to the site in person to obtain the RFID identification code, thereby restricting the actual inspection of the staff. At the same time, GPS is integrated with embedded GIS to ensure the in-place rate of the pole and tower inspection based on the received GPS signal, and to prevent missed inspections and in-place inspections.
The system can also perform statistics, summary, and analysis of various historical data stored in the database, and display the frequency and target of a certain fault in a certain period of time in the format of various charts or reports, for the manager to analyze through prediction Strengthen management and formulate response measures to achieve the purpose of prior control in order to reduce the incidence of accidents and ensure the smooth progress of safety and mass production.
