Location, search and rescue system for mining personnel

Abstract

The invention discloses a location, search and rescue system for mining personnel. The system comprises a location server, a monitoring terminal, a wired communication sub-system, wireless communication base stations, a location device and a rescue device, wherein the wired communication sub-system mainly comprises an optical fiber, a light splitter and a wireless exchanger; the wireless communication base station mainly comprises an explosion-proof tank, a power supply, a standby battery, a wireless access device, an antenna and the like; the wireless communication base stations are arranged under the coal mine at intervals, and connected with the location server on the coal mine through the wired communication sub-system; the location device is wirelessly communicated with the wireless communication base stations; the location server is used for locating the personnel through location devices carried by the mining personnel, and periodically sending the information such as the location and the identity number of the personnel to the location server; the rescue device can be directly wirelessly communicated with the location device; and the rescue system can locate the trapped personnel, so that the useless work is avoided, the precious rescue time is saved and the rescue efficiency is increased. The location, search and rescue system is a comprehensive system integrated with the functions such as tracking and locating of the mining personnel, dispatching management, and searching and rescuing for a disaster.

Description

technical field [0001] The invention relates to an underground personnel positioning search and rescue system. The invention specifically relates to technical fields such as WI-FI wireless communication and wireless positioning. Background technique [0002] Downhole personnel positioning is an important measure for safe production. Over the years, people have used various methods to detect the location of underground personnel. When an accident occurs in a mine, the positioning system can provide an important reference for personnel search and rescue. But the current positioning and search and rescue system has the following deficiencies. [0003] At present, the actual use is mainly based on radio frequency identification technology (RFID). RFID uses radio frequency to carry out non-contact two-way communication to achieve the purpose of identification and exchange data. Different from other contact identification technologies, the RFID system can realize automatic iden...

AI Technical Summary

Problems solved by technology

[0004] 1. The RFID communication distance is limited, and the farthest barrier-free communication distance of the active RFID card is 80 meters;

[0005] 2. The RFID card reading and writing equipment is large in size and not easy to carry

[0006] 3. Not convenient for two-way communication

Unable to support search and rescue positioning

[0009] 2. The communication of Zigbee wireless sensor network must have network support, and point-to-point communication is not supported

When there is no network support, the positioning terminal cannot communicate with other devices

[0010] 3. Unable to know the current activity status of the trapped person
