Downhole personnel management system for coal mine

Abstract

The invention relates to a downhole personnel management system for a coal mine. The system comprises ground equipment, downhole equipment and a plurality of identification cards worn by downhole miners. The ground equipment is connected with the downhole equipment via cables and comprises an aboveground mining lightning arrester, the aboveground mining lightning arrester is connected with a safety fence, and the safety fence is connected with a computer via a transmitting interface. The downhole equipment comprises a downhole mining lightning arrester and at least one mining substation connected with the downhole mining lightning arrester. Each identification card is provided with a central processing unit, a low-frequency signal receiving module, a low-frequency signal transmitting module, a high-frequency signal receiving module and a high-frequency signal transmitting module. The mining substation comprises a central processing unit, a storage module, a low-frequency signal receiving module, a low-frequency signal transmitting module, a high-frequency receiving module and a high-frequency signal transmitting module, and supplies power via an intrinsic safety electric source. The downhole personnel management system for the coal mine utilizes the radio frequency technique, and can be applied for attendance record, position detection and identification reliably, accurately and timely.

Description

technical field [0001] The invention relates to a management system for underground personnel in coal mines, in particular to a management system for identifying the identity of underground personnel in coal mines by using radio frequency technology, and belongs to the technical field of safety management for underground personnel in coal mines. Background technique [0002] In recent years, accidents in coal mines have been frequent, and most of the accident coal mines first encountered the two major problems of counting the number of people trapped underground and counting the location and area of ​​the trapped people when implementing rescue. As leaders at all levels and competent departments pay more and more attention to the safety of coal mine personnel, people try to use various means to strengthen the safety management of coal mine personnel. In the existing technology, most of the RFID technology is used for the safety management of underground personnel in coal min...
