Abstract

The invention discloses a positioning and tracking system of an underground / roadway moving object, comprising underground positioning and tracking systems distributed under a detected mine and ground monitoring systems distributed on the ground; two-way communication is conducted between the underground positioning and tracking system and the ground monitoring system; the underground positioning and tracking system comprises a plurality of wireless radio-frequency labels, a plurality of wireless signal receiving and transmitting devices and a plurality of card readers which are respectively carried by underground workers, are internally stored with the information of the identity and engaged job category information of a cardholder, can read the stored information in the wireless radio-frequency labels within respective signal coverage area in real time, and synchronously upload the read information and the internally-stored information to the card reader of the receiving and transmitting device; and the wireless radio-frequency labels are distributed on a coal mining work surface or a coal mining roadway. The positioning and tracking system has reasonable design, convenient installation and distribution, low cost, complete function and good use effect, and also improves the coverage area correspondingly while saving the cost.

Description

technical field

[0001] The invention relates to a mobile object positioning and tracking system, in particular to an underground / roadway mobile object positioning and tracking system. Background technique

[0002] In recent years, mine accidents have occurred frequently. Due to the complexity of the mine situation, the rescue work of miners is very difficult. If you can know the precise location of the workers in the mine in time at ordinary times, the casualty rate of the accident will be greatly reduced in the event of an accident. Therefore, the positioning of underground personnel has always been an urgent task in coal mining. Now researchers have proposed many solutions, mainly including RFID-based underground personnel positioning methods and PHS-based underground personnel positioning methods, etc., but Little success.

[0003] Among them, the working principle of the underground personnel positioning method based on RFID is to use radio frequency identification tec...
