In order to facilitate more reasonable scheduling management. When an accident occurs, rescuers can also quickly understand the location of relevant personnel based on the data and graphics provided by the Shanghai Xiupai underground personnel positioning and attendance system, and take corresponding rescue measures in time to improve the efficiency of emergency rescue work.

Shanghai Xiupai underground personnel positioning and attendance system is a comprehensive application system integrating underground personnel attendance, tracking and positioning, post-disaster first aid, and daily management. It is also the domestically most advanced technology, the most stable operation, and the most professionally designed underground positioning system. The realization of this scientific and technological achievement will bring new opportunities for the safety production and daily management of coal mine enterprises as well as emergency first aid.

The underground personnel position monitoring (location attendance) system involves computer software, database, electronic circuit, explosion-proof intrinsically safe power supply, digital communication, wireless identification technology, etc. Therefore, in addition to its functions, the stability, reliability, anti-interference ability, fault tolerance and abnormal protection are also fully considered when designing the scheme. The project plan determines to use the existing mature coal mine high-speed industrial Ethernet plus fieldbus system as the main transmission platform, develop corresponding underground personnel tracking and positioning sensors, personnel wireless identification cards and other equipment and system connection, through underground personnel tracking and positioning sensors and attendance The special management software and the main system exchange background data with a standard special database to realize the tracking and positioning and safety management of underground operators. The overall design of the system is mainly reflected in:

1. Realize the effective identification and monitoring of the entry and exit of coal mine operators, so that the management system fully reflects “humanization, information and high automation”, and realizes the goal of digital mines.

2. Provide coal mine management personnel with various management information such as personnel entry and exit restrictions, attendance operations, monitoring and control, etc. Once a safety accident occurs, the system can immediately detect the personnel and personnel on the work surface within 10-30 meters of the accident site. Its quantity ensures the efficient operation of emergency rescue and safety rescue work.

3. The system design is safe, expandable, easy to maintain and easy to operate.

4. Easy networking, BS structure, easy to realize network monitoring of counties, cities, provinces and wider regions.

The Shanghai Xiupai underground personnel position monitoring system is supported by the main computer of the ground monitoring center and the system software, through the data transmission interface and the communication light/cable laid along the roadway, regularly performs data inspection and information collection on the wireless data sensors installed in the underground. , The wireless data sensor will automatically collect the information of the identification card within the effective recognition distance, and according to the system instructions, transmit the relevant data to the ground center station through the transmission network. After the data information is analyzed and processed, the dynamic distribution of underground personnel (or moving targets such as locomotives) can be reflected in the main computer interface in real time, so as to realize the purpose of digital management of underground safety status on the well.

Following the principle of “unified card issuance, unified equipment, and unified management”, the identification card is regarded as an “entry permit” or “tunnel access permit”, and the “one person, one card” system is implemented according to the permitted personnel.

1) According to mine monitoring requirements, wireless data sensors with access direction and time recognition capabilities are installed in underground tunnels, chambers, work surfaces and other locations, and they are connected to each other as underground high-speed industrial Ethernet through optical fiber data transmission interfaces, thereby forming a complete communication line.

2) After the coal mine production unit enters the relevant information of the staff, the staff in the underground mine will issue and equip the identification card.

3) The system database records the basic information of the person corresponding to the identification card, including basic information such as name, age, gender, team, type of work, position, photo, and validity period.

4) Workers entering the tunnel must carry the identification card with them. When the cardholder passes through the location where the identification system is set up, the system will recognize the card number. The system will read the card number information and transfer the cardholder’s road section, time and other information through the system transmission network. It is transmitted to the ground monitoring center for data management, and at the same time, a prompt message appears on the large geographic information screen wall to display the name of the passing personnel. If the detected wireless identification card number is invalid or enters a restricted channel, the system will automatically alarm, and the security monitoring center staff on duty receives the alarm signal and immediately executes the relevant safety work management procedures.

5) The production unit can authorize the management of the identification card according to the production plan. The scope of authorization includes: tunnels or work surfaces that the employee can enter. In order to prevent irrelevant and illegal persons from entering the tunnel or work surface, the system is equipped with a time management module for access to the tunnel or work surface of the card, as well as card failure and loss reporting.

6) Once a safety accident occurs in the tunnel, the monitoring center can know the basic situation of the trapped person in the first time. The rescue team uses a mobile remote identification device to easily detect the location of the person in distress within a range of 10-30 meters, which is convenient for rescue. The safe and efficient operation of work facilitates the development of accident rescue work.

7) The system can automatically generate report data on the statistics and management of attendance operations to improve management efficiency.

(3) General technical conditions and use management specifications of the underground coal mine personnel position monitoring system of the State Administration of Work Safety

1) Query and display the number, distribution and identity of a certain place underground at any time.

2) Query the current actual position and movement track of one or more personnel in the well.

3) Record a series of information such as the arrival/departure time and total working hours of relevant personnel at any location, so as to supervise and implement whether important inspection personnel (such as gas detection personnel) conduct on-site inspections on time and on-site, or perform various items. The detection and processing of data fundamentally eliminates related accidents caused by human factors.

It can count the personnel entering and exiting the well, realize the attendance record of the personnel entering and exiting the well, and create and print various information reports of the personnel entering and exiting the well (such as: logging time report, attendance monthly report, overtime report, absentee report, etc.), which is convenient for management personnel to query And management.

The central station of the system and the network terminal can be networked in a local area network, so that all terminals on the network can share information at multiple points within the scope of use authority, so that multiple mine departments and leaders can share monitoring information, system comprehensive analysis information, and query information at different locations at the same time. Class data report.

It has functions such as zooming in, zooming out, moving, ruler distance measurement, field of view control, center movement, soil layer control, map printing, etc., and supports multiple graphic formats. Both mouse and keyboard can be operated, and real-time multitasking is fully supported.

For the designated restricted area, if an unauthorized person enters, a real-time alarm will sound, and the number and identity of the person entering the restricted area will be displayed.

Once various accidents occur, the upper computer can immediately display the number of personnel, personnel information, personnel location and other information at the accident site, which greatly improves rescue efficiency and rescue effectiveness.

The tunnel wall-mounted design of the system products ensures that the system can operate continuously in harsh environments and provides power supply for 2 hours after power failure.

When the underground personnel tracking and positioning sensor loses contact with the ground center station, it can still work independently and automatically store personnel monitoring data. At the same time, the sensor has a Chinese character LCD display personnel code and clock function, and the remote control can be used to query and record.
