Coal mine down-hole personnel positioning and mash gas concentration dynamic monitoring method and system

Abstract

The present invention discloses methods and system for coal mine downhole personnel locating and mash gas concentration dynamic monitoring, the system includes: CAN bus network, wireless sensor network and data conversion device. CAN network connects with wireless transducing network connections by data switching device, and by using wireless sensor network self-organizing, multi- skip, data acquisition and processing, and wireless communicating characteristic, the invention designs a system about out-in well personnel work attendance and moving vehicle zone location in coal mine well, and a system for monitoring gas dynamic concentration. The system and method overcome the current deficiency of operating gas monitoring system and personnel position location system respectively, not only personnel zone location and dynamic gas testing is realized, but also allocation is obtained about personnel arrangement and moving mechanical equipment before the accident, this provides reliable data for rescuing miner and avoiding second disaster.

Description

technical field [0001] The invention relates to a coal mine personnel positioning and gas concentration detection system, in particular to a system using wireless sensor technology to realize personnel positioning and gas detection functions. Another feature of the system is that the personnel positioning and dynamic gas detection and alarm functions are combined in one In a set of systems, a comprehensive intelligent management system for underground coal mines has been realized. Background technique [0002] As the world's largest coal-producing country, my country's coal mine safety accidents occur frequently. In order to protect the life safety of miners, the state attaches great importance to the safety of coal mines and continuously strengthens the supervision. my country's large and medium-sized coal mines and small township coal mines have been equipped with a large number of coal mine safety production monitoring systems. The promotion and application of these safet...

AI Technical Summary

Problems solved by technology

However, the monitoring equipment currently used in underground coal mines generally has problems such as imperfect functions, complicated maintenance and operation, and low efficiency.

Most coal mines still have difficulties in the management of personnel entering the well. It is difficult for the above-ground personnel to timely grasp the underground situation and the dynamic distribution of personnel and operating conditions. It is impossible to monitor the hidden dangers of underground accidents at any time.

Once an accident occurs, the existing monitoring system is difficult to monitor underground gas, temperature, pressure, toxic and harmful gases, etc. It is difficult to determine the location of underground personnel and cannot provide reliable information for rescue

[0003] The existing coal mine underground monitoring system and the underground personnel attendance and positioning system are two separate systems, which are independently controlled by two sets of computer control systems. The personnel monitoring system uses RFID radio frequency technology, which cannot realize dynamic gas monitoring

Once a safety accident occurs, it is impossible to know the gas situation at the location of the underground personnel, which will affect the evacuation and rescue of personnel
