Coal mine underground monitoring and staff locating system

Abstract

A coal mine underground monitoring and staff locating system is a comprehensive operation system combining underground staff attendance, track location, after-disaster first aid, and daily management, and is the most advanced, stable and professional operation system; the system comprises a ground computer control centre, a transmission interface, a tag card, a foundational base station, a locating base station, a blast-proof and intrinsic safety type multi-way power box, and other matching equipment. The received staff condition signal is sent to the ground transmission interface through the locating base station by using a radio emission technique and sent to a host to process; the host executes judging and alarming, data counting and storage, display, man-machine conversation, staff line monitoring, and control and printing for the received monitoring signal. An alarm device is set in the special area of the coal mine such as a key area and a limited area so that the effective information is supplied to the after-disaster first aid and that the casualties in the coal mining accidents are also reduced.

Description

technical field [0001] The invention belongs to the field of electronics and information, and relates to a coal mine underground monitoring and personnel positioning system Background technique [0002] Although relevant state departments have repeatedly issued regulations on coal mine management, accidents in coal mines continue to occur, causing serious casualties and economic losses. The most important reason is that coal mines are not equipped with corresponding facilities such as monitoring and personnel positioning systems, resulting in major coal mine accidents, the distribution of underground personnel is unclear, and timely rescue cannot be performed. According to the characteristics of coal mine operators with high mobility underground, the ground personnel are difficult to grasp the distribution of underground personnel and the progress of operations in a timely manner, and it is impossible to know exactly where they are after going down the mine, the daily attend...

[0002] Although relevant state departments have repeatedly issued regulations on coal mine management, accidents in coal mines continue to occur, causing serious casualties and economic losses

The most important reason is that the coal mine is not equipped with corresponding facilities such as monitoring and personnel positioning systems, resulting in major coal mine accidents, the distribution of underground personnel is unclear, and timely rescue cannot be carried out.

According to the characteristics of coal mine operators with high mobility underground, the ground personnel are difficult to grasp the distribution of underground personnel and the progress of operations in a timely manner, and it is impossible to know exactly where they are after going down the mine, the daily attendance of miners is generally managed through the distribution of miner's lamps, but There are many problems such as chaotic management. When a mining accident occurs, it is difficult to count the actual number of people underground and the specific location of the miners, which brings many difficulties to the rescue work.
