“Underneath Coal Mine Personnel Positioning and Tracking Management System” organically combines cutting-edge long-distance radio frequency identification technology, network communication technology and automatic control technology, and solves the problem that the system products are applied to the safe operation of equipment in underground coal mines, network data communication, and long-distance data. Technical problems such as transmission, signal conversion interface and information processing will provide effective scientific and technological support for underground coal mine personnel monitoring, control, monitoring and tracking management, as well as production statistics management, and will forcefully promote the economy of coal mine enterprises. developing.
Problems facing the coal industry
In recent years, the number of high-gas mines in coal mines has been increasing. How to strengthen safe production and improve the efficiency of search and rescue work has been put in front of the competent authorities and leaders at all levels of the country. When we analyzed the recent major accidents in several coal mines, we found that:
(1) The information communication between the ground and underground personnel is not timely;
(2) It is difficult for surface personnel to dynamically grasp the distribution and operation of underground personnel in a timely manner, and to accurately locate personnel;
(3) Once a coal mine accident occurs, the efficiency of emergency rescue and safety rescue is low, and the search and rescue effect is poor.
For this reason, how to correctly handle the relationship between safety and production, safety and benefit, how to accurately, real-time, and quickly perform coal mine safety monitoring functions, effectively manage miners, and ensure the efficient operation of emergency rescue and safety rescue is particularly important and urgent. Facing the new situation, new opportunities and new challenges, the leaders of the national competent departments at all levels put forward high requirements and expectations for work safety. We believe that improving the level of information management of production safety and strengthening the long-term safety production mechanism with disaster prevention and search and rescue as the main goals are the only way for my country’s production safety work.
Brief Introduction of Underground Personnel Positioning and Tracking System
The underground personnel positioning and tracking system is mainly used for underground and tunnel operations such as coal industry. The system tags can be carried by individuals or placed on vehicles or equipment, and their locations and the latest recorded information can be transmitted to the main control room.
The hardware of the personal location tracking system mainly includes a tracker and a tracking monitoring station. The tracker is used to transmit the carrier ID number, and the tracking monitoring station is mainly used to record these ID numbers and transmit the data to the PC in the central office or main control room.
The software of the personal location tracking system is mainly used to store the records and real-time positions of all trackers. The software can provide users with functions such as classification, filtering, search and report generation, and use these functions to complete data realization and comprehensive records.
The research and development of the personal positioning tracking system is in full compliance with the safety standards and requirements of the underground industry, with stable performance, reliable quality, and easy operation. It has made outstanding contributions to improving the safety and effectiveness of the modern underground working environment. The system records the historical details of trackers, users, tracking monitoring stations and time. Users can use query tools according to their own query purposes.
This system is an automatic identification information technology product integrating computer software and hardware, information collection and processing, wireless data transmission, network data communication, automatic control and other technologies. Contact information collection and processing realizes the automatic recognition of people, vehicles, and objects in different states (moving, stationary), so as to realize automated management of goals.
The product integrates high-tech radio frequency identification technology, uses dual-frequency point long and short wave frequencies to achieve reliable full-duplex wireless data communication, substation equipment, control equipment, communication interfaces and RFID identification cards are explosion-proof and intrinsically safe Type design, with long working distance, can adjust the recognition range of the system arbitrarily, recognizes no “blind zone”, strong signal penetration, high security and confidentiality, no electromagnetic pollution to the human body, strong environmental adaptability, can identify multiple people at the same time, It is convenient for underground network connection and digital transmission and other performance advantages. At present, this new information collection, storage, transmission and processing technology will play a very important role in the monitoring, control, monitoring and tracking management of underground personnel in coal mines.
This system product has been independently designed in accordance with the technical requirements of coal mine safety production and national safety standards, which can fully meet the requirements of automation and information management of underground personnel monitoring and tracking management, and can make full use of the existing coal mine monitoring system platform resource networking Operation, effectively saving investment.
The application of radio frequency card identification technology to the coal mine underground management system is to establish a complete, flexible and real-time underground management system, including the planning and arrangement of underground workers, the authority management of workers entering and exiting the roadway, the distribution of roadway personnel, and the operation Workers’ data and safe material flow are managed to realize the informatization and visualization of underground management, and at the same time improve the level of coal mining production management and operational safety.
