Mine down-hole visual positioning and multifunctional safety monitoring network system

Abstract

A visual positioning and multi-functional safety monitoring network system used in a mine well adopts a method of radio frequency information identification positioning. Workers and mobile equipment in the well are equipped with a radio frequency identification card. A single-stage or multi-stage information acquisition base stations are arranged in the well according to the distribution of operating districts, and various sensors are connected to sensor ports at the base stations based on the requirement of mine monitoring items. As a person carries the identification card when entering the well and the information acquisition base stations are arranged from a well inlet to every operating points, the card carried by the person will be read when the person passes each information acquisition base station, and the station will transmit the positioning information read from the card and the information of all monitoring parameters acquired by the sensors to a monitoring mainframe on the ground. Moreover, a set of multi-functional comprehensive monitoring system application software is used to realize the dynamic management and all-round safety monitoring of the person in the well.

Description

technical field [0001] The present invention is a multifunctional safety monitoring network system integrating visual positioning of mine personnel or equipment, gas monitoring, ventilation monitoring, dust measurement and control, mine temperature and mine pressure measurement and control. The visual positioning of personnel or equipment is used as a platform, and other sensors are connected to form a multi-functional security monitoring network system. It is mainly used for underground safety monitoring and management of coal mines, and can also be used for safety monitoring of various other underground mines. Background technique [0002] In recent years, the number of mine accidents has been increasing. According to a survey by the Research Center of the State Administration of Work Safety, the death rate per million tons of coal mines in my country is much higher than that of some developed countries in the world, 120 times that of the United States, and 20 times that o...
