Intelligent management system for coal mine production safety

Abstract

The invention discloses an intelligent safe management system, which integrates the personnel location, the attendance, the searching, the risk gas monitoring, the speech communication and the production process monitoring. A monitoring center server and an operating terminal are connected with a wireless communication device through a switch. A wireless intelligent sub-station is connected with the switch through an optical cable. A wireless ad hoc network is formed among the wireless intelligent sub-station, the wireless communication device and an intelligent location card. A production process monitoring unit is connected with the switch through the wireless intelligent sub-station or the wireless communication device. A software system is used for the collection, the recognition, thetransmission, the monitoring and the management of information. The software system can accurately monitor, locate and manage underground work personnel. A hand-held searching device can be used for finding the location card under emergency conditions. And the movement path of the location card is displayed in real time or reappears on the operation terminal. A risk gas sensor can transmit monitoring data in the region to the monitoring center server. Talking is possible among wireless talking devices and a control center above a well.

Description

technical field [0001] The invention relates to an intelligent safety management system integrating personnel positioning, attendance check, search, dangerous gas monitoring, voice communication and production process monitoring. Background technique [0002] Underground coal mine wireless communication is constrained by the propagation characteristics of radio waves in the "limited space". The frequency used for communication should be higher than the "cut-off frequency" of the mine, and the short-wave frequency with better diffraction performance cannot be used, while the ultrashort wave and microwave The frequency is affected by the irregular terrain underground, and the transmission distance is greatly reduced. Therefore, a combination of wired and wireless communication methods (such as leakage communication and induction communication, etc.) are basically used underground. Such methods actually require The use of wired networks to establish fixed basic communication fa...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to overcome the defects of the existing coal mine underground intelligent safety management system, and realize a coal mine production safety intelligent management system by using wireless networking technology, so that the information of the operators entering the well can be collected and tracked in time. Real-time positioning of the operator's location, collecting data from each production process monitoring unit, and transmitting the data to the ground monitoring center to provide the most urgently needed basic information for emergency rescue work in mining accidents
