Problems solved by technology

[0002] my country's coal mine safety accidents occur frequently, and some coal mines cannot provide the number and exact location of underground personnel after mine disasters occur, which seriously affects the rescue work of mine disasters
At present, the data transmission medium of domestic coal mine underground monitoring and monitoring systems is mainly cables, and the transmission method is analog. This monitoring and monitoring system has the following defects. The underground operating environment is harsh and the cables are easily damaged. Once this happens, it is difficult Determining the fault point of the system will affect the normal use of the system; in addition, the system uses analog quantities for data transmission and exchange, which has poor anti-interference ability and is prone to false alarms; currently, all kinds of systems put into operation in coal mines cannot provide dynamic positioning and voice communication for underground personnel , the victims could not be rescued in time

Embodiment Construction

[0019] A method for realizing real-time monitoring of coal mine underground personnel by using IEEE802.15.4 network, comprising the following steps:

[0020] (1) One or more networks with tree, star, and mesh structures are set up in the underground roadway, and each network consists of a base station (Tunnel Position Gateway--TPG) and several routers (Tunnel Position Router--TPR) composition. The base station (TPG) is arranged at the beginning of the network, along the direction of network extension, multiple routers are set at a certain distance, and the locator (Tunnel Position Device--TPD) is placed on the underground operators. IEEE802.15.4 wireless network protocol is used to realize wireless transmission between the base station, router and locator, and data exchange is carried out between the base station and the control computer on the well via Ethernet or RS485 communication protocol;

[0021] (2) Carry out network initialization, the base station sends the initiali...

Abstract

The invention relates to a method for real-time detecting under-mine worker via IEEE802.15.4 technique. Wherein, it arranges one or several networks at tree, star or mesh structure in the under-mine channel; each network is formed by one base station and several routes; the worker is arranged with positioning device; the base station, route and positioning device are connected via IEEE802.15.4 wireless network protocol; the base station and superior control computer are connected by Ethernet or RS485 communication protocol; the RRSI value of wireless electric signal between network nodes is relative to the spatial distance, via self learnt network, said relationship can be fixed, and the positioning device can via said relationship and tested RRSI value, fixes the spatial position and sends the information to the computer control system to real-time detect the under-mine worker.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety, in particular to a method for realizing real-time monitoring of coal mine underground personnel by using IEEE802.15.4 network technology. Background technique [0002] Coal mine safety accidents occur frequently in our country. After some coal mine disasters occur, the number and exact location of underground personnel cannot be provided, which seriously affects the rescue work of mine disasters. At present, the data transmission medium of domestic coal mine underground monitoring and monitoring systems is mainly cables, and the transmission method is analog. This monitoring and monitoring system has the following defects. The underground operating environment is harsh and the cables are easily damaged. Once this happens, it is difficult Determining the fault point of the system will affect the normal use of the system; in addition, the system uses analog quantities for data transmission...
