Abstract

The invention discloses an accurate underground wireless positioning system and method based on the combination of the WiFi and a gyroscope. The underground wireless accurate positioning system comprises a ground part and an underground part. The ground part is mainly composed of a server and a corresponding database. The underground part mainly comprises a mobile terminal, an electronic tag and a wireless AP. The mobile terminal is composed of a positioning module, a processing module, a WiFi module and a power source part. The positioning module is mainly composed of a WiFi module and a gyroscope data collecting and processing module. The gyroscope is introduced to the underground wireless accurate positioning system, the positioning technology of the gyroscope and WiFi combination is adopted, and very high positioning accuracy can be achieved; in addition, the integrated wireless AP can be directly connected through an optical cable or a network cable, a set of wired routers are formed, data, voice, video images and other information sent by the mobile terminal are transmitted to a ground dispatching center through the wired routers formed among substations, and various underground comprehensive service information can be transmitted.

Description

technical field [0001] The invention belongs to the technical field of underground wireless precise positioning in coal mines, and relates to an underground wireless precise positioning system and method based on the combination of wireless WiFi and a gyroscope. Background technique [0002] The personnel positioning system is a subsystem of the six systems of underground safety and risk avoidance, which is helpful for the collaborative management and scheduling of operators in the complex environment of coal mines, and is of great significance to coal safety production; , quickly understand the location of underground personnel, take corresponding rescue measures in time, improve the efficiency of emergency rescue work, and minimize disaster losses. [0003] At present, experts at home and abroad have proposed to apply wireless communication technologies such as ultrasonic, infrared, Bluetooth, WiFi, radio frequency identification (RFID), ultra-wideband (UWB), ZigBee, and a...
