Mine underground intelligent wireless monitoring and positioning system

Abstract

The invention discloses a mine underground intelligent wireless monitoring and positioning system comprising a positioning and monitoring module of a mobile carrier, a wireless and wired communication seamless switching wireless base station, a data analysis processing and transmitting relay station, a ground information system processing workstation and a ground sensor automatic calibration system, wherein the data analysis processing and transmitting relay station receives data from a mobile carrier positioning and monitoring module and data from the wireless and wired communication seamless switching wireless base station via a wireless ZigBee module or a wired industrial CAN bus interface, and sends to the ground information system processing workstation by optical fibers or the Ethernet; the automatic calibration system of a ground sensor carries out wireless communication with the mobile carrier positioning and monitoring module via the wireless ZigBee module. The invention has the advantage of solving the problems of realizing perfect mine monitoring and precise positioning; and because the invention adopts double power supply by batteries and an AC power source, AC is cut off when accidents happen underground, and batteries continue working. In addition, the invention is convenient and simple for networking.

Description

technical field [0001] The invention relates to an intelligent wireless monitoring and positioning system for underground mines, belonging to the field of underground positioning and monitoring for mines. Background technique [0002] The establishment of a complete monitoring system and an accurate personnel positioning system in coal mines is a prerequisite for implementing the "prevention first" safety production concept. At present, some patents involve research in this area. [0003] CN 201096877Y discloses a wireless positioning system based on ZIGBEE. The main problems of this patent are: (1) only using current information for positioning, rather than combining historical data and current data for positioning; (2) no fusion of mine monitoring functions. [0004] CN 101369944A proposes a mine wireless positioning system based on ZIGBEE and RFID and a layout method thereof. Use RFID for positioning, and send positioning information through ZIGBEE. The main problems ...

AI Technical Summary

Problems solved by technology

The main problems of this patent are: (1) only using current information for positioning, rather than combining historical data and current data for positioning; (2) no integrated mine monitoring function

The main problems of this patent: (1) It does not combine positioning and monitoring; (2) RFID is one-way; (3) It only uses current information to locate, rather than combining historical data and current data for positioning;

However, the strength of the wireless signal is subject to too many interference factors. For example, when the human body enters the scene, it will also affect the strength of the wireless signal.

Therefore, the positioning is not accurate

[0006] CN200620101832.3 The mine staff positioning system proposes a concept of wireless positioning and monitoring, but for the key issue of mine positioning: how to use the wireless system for accurate positioning, this patent does not propose a new algorithm

Like the patent CN201408358Y, (1) the calibration of the sensor is not solved, so it is easy to often cause false alarms; (2) there is no effective positioning scheme
