1. Analysis of the status quo of the industry:
With the deepening of reform and opening up and the development of the national economy, various hidden dangers of public security accidents in railway transportation have gradually increased, and various unexpected accidents. The problems basically exist in basic road conditions such as railway subgrades, rails, turnouts, signal lights, and railway bridges. Inspections; inspections of railway locomotive instruments and meters; used for inspections of facilities and communication lines along the railway. Although the management center allows line inspectors and maintenance personnel to conduct regular inspections, the accident rate accounts for more than 80% due to the negligence of duty, mental paralysis, and the existence of fluke. Railway inspection methods currently in use mainly include information button-based inspection systems and RFID-based inspection systems.
Electronic patrol (change) system based on information buttons
The information button is an automatic identification chip, which is installed on the inspection equipment. The inspectors hold the inspection instrument and touch the information button to read the information. When performing tasks, the record results of the patrol instrument are transmitted to the patrol management server for the relevant management personnel to examine. The defects of this kind of inspection instrument are: 1. The inspection instrument and the information button must be very accurately contacted to read the information, which is very inconvenient to operate, especially at night. 2. The information button needs to be in contact with the inspection instrument, which must be exposed and easily damaged. 3. The information button is easy to be contaminated, resulting in poor contact. RFID-based inspection (change) system
The RFID-based system is a radio frequency automatic identification technology that uses radio frequency to realize non-contact two-way communication. The system is composed of a card reader and a radio frequency card. The basic feature of RFID is that the card reader and the radio frequency card do not need to be in direct contact, and the energy transmission and information exchange between them are realized through electromagnetic coupling or inductive coupling. Although the feature of non-contact reading information of RFID overcomes the shortcomings of the information button system, it also has its shortcomings, mainly: 1. The RFID inspection system records the information of discretely distributed inspection points, and cannot record the inspection path. , Cannot be used for line inspection. 2. The system only records the time when the radio frequency card is read. It is possible that the inspector will leave after reading the information, and not carefully check the equipment. For the equipment that needs to be unpacked and inspected, it is impossible to check whether the inspector has checked according to the operating specifications. equipment.
2. Industry demand analysis
The management goal of the inspection work is to reduce costs, improve work efficiency and management level, and the requirements for the inspection management system:
1. The system construction is simple, the cost is low, and the maintenance is very simple.
2. Standardize the inspection work so that the inspectors can inspect according to the designed route.
3. You can view the position dynamics and form trajectories of inspectors in real time.
4. The inspection personnel complete the required inspection items at the inspection points, and collect the operating status and data of the equipment.
5. When there is a problem, the inspector can communicate with the background in real time by means of graphics, video, etc., and solve the problem online.
6. Effectively use historical data such as equipment operating conditions and operating parameters, query and analyze equipment defects, and provide auxiliary decision-making for equipment selection. In order to detect and eliminate equipment and process defects in time, prevent accidents, and ensure the safe and stable operation of the railway.
7. Leaders at all levels and relevant departments can easily check the inspection status through the Internet.
3. Introduction of GPS inspection management system
After years of technical development and research, Shijiazhuang Zhichuang Technology has developed a new high-end inspection system and successfully developed a GPS inspection management system. We applied GPS and mobile communication technology to the system to achieve GPS inspection and real-time management functions, and added The electronic map-based resource management module enables users to obtain a simple and practical GIS system while using the inspection management system. It has extremely high cost performance and reliability. It has been widely used in security, heating pipe networks, and gas Various safety inspection management fields such as pipelines, telecommunications, coal mines, railways, petroleum and petrochemicals, agriculture, animal husbandry, and forestry.
The GPS inspection management system draws on the successful experience of the electronic patrol system, perfectly combines inspection point assessment with GPS trajectory, and replaces traditional radio frequency inspection points with virtual coordinate inspection points, so that you can clearly see the arrival of inspectors The time left for each inspection section allows enterprise managers to clearly see the work status of the inspectors and clearly show the inspection status of the entire line. The GPS inspection management system consists of a handheld terminal (Android phone) and a management platform.
4. The main functions of the GPS positioning and inspection system management platform:
1. Real-time positioning: the manager can view the current position and status of the inspector in real time.
2. Historical trajectory playback: You can view the walking route and inspection status of the inspectors in a certain period of time, and reproduce the situation on the spot at that time.
3. Line setting: The server can reasonably set the inspection lines of the inspectors to maximize the efficiency of the inspection work and reduce the work intensity of the inspectors.
4. Inspection and observation: Through the front pictures returned by the inspectors, the command center can effectively understand the situation of the petroleum facilities, conduct reasonable inspection instructions, and improve the scientific nature of the inspection work.
5. User management: add new users and assign permissions
