At present, there are many hidden dangers in coal production in our country. The information communication between ground and underground personnel is not timely, and it is difficult for ground personnel to dynamically grasp the distribution and operation of underground personnel in time. Once an accident occurs, the efficiency of emergency rescue and safety rescue is low, and the rescue effect is low. Difference. Therefore, through the implementation of RFID technology underground, it can achieve accurate, real-time and rapid performance of coal mine safety monitoring functions, ensure the efficient operation of emergency rescue and safety rescue, and correctly handle the relationship between safety and production, safety and benefits, and achieve national safety Production requirements.
The underground coal mine personnel management system is an automatic identification product integrating computer software and hardware, data acquisition, data transmission, automatic control and other technologies. This product uses non-contact remote automatic data acquisition and processing of moving targets in the tunnel. Realize the automatic identification of moving or static states of people, vehicles, objects, etc., and multi-disciplinary integrated applications can provide coal mine managers with management information in various aspects such as access restrictions, attendance operations, monitoring and monitoring. It is summarized as follows:
◆The underground coal mine personnel management system can realize the accurate reading of the target
* The downhole bus and the uphole network form a networking system
* The software realizes personnel monitoring, statistical analysis, query and other management functions
◆Monitoring and digital informatization of mines
* Downhole emergency rescue, accident investigation and safety management
* Digital informatization of mines
The product has an explosion-proof safety design, the system has a long operating distance, can adjust the identification range of the system according to needs, recognizes no blind areas, strong signal penetration, high security and confidentiality, no electromagnetic pollution to the human body, strong environmental adaptability, and simultaneous Performance advantages such as identifying numerous targets and facilitating network connection.
This product combines the characteristics of safe production in coal mines and the characteristics of RFID technology, and uses its own technical force to design and manufacture intelligent positioning equipment suitable for coal mines and with independent intellectual property rights. This brand-new information collection, storage, transmission and processing technology has quickly attracted wide attention from colleagues at home and abroad, and has important practical significance for the positioning and tracking management of underground personnel in coal mines.
The entire product consists of a downhole data acquisition system and a surface safety monitoring and management system.
The underground data acquisition system is composed of two parts, the underground card reading sub-station and the mine active identification card. It has the following characteristics:
◆ Objects with radio frequency security cards are automatically identified and read when they enter the monitoring range of the card reading substation
◆ Long-distance, multi-card simultaneous, fully automatic reading
◆ This system has accurate real-time positioning function, and accurate tracking and positioning of the target
◆ The underground card reading sub-station can be networked to form a multi-point monitoring system and perform positioning
Underground card reading station:
◆ The whole is placed in an explosion-proof shell
◆ Read through RFID module
◆ Realize data filtering, storage, forwarding, communication and networking through the control system
◆ 485 interface / optional optical fiber interface
◆ The underground card reading sub-station can be networked to form a multi-point monitoring system and perform positioning
Mining active identification card:
◆ Adopt ID method
◆ Confidentiality
◆ Unique
◆ With accuracy
Install underground card reading substations at all important monitoring points. When underground workers carrying mine active identification cards enter the monitoring range, the system automatically recognizes the personnel information and transmits the data to the ground safety monitoring center in real time. In the event of an accident , Through the system, you can immediately know the number and time of the last location of the trapped personnel on the work surface, ensuring the efficient operation of rescue and safety rescue work.
