Study On Communication Interface And Underground Substations Of The Management System Of Distributed Coalmine Underground Personnel And Equipment Safety

In recent years, greatly heavy coalmine accidents have frequently occurred. After the accident, we delayed the best time for rescue often due to the lack of necessary emergency rescue system or the rescue system that is imperfect and smooth, which leads to the scope of the accident expanded and the extent of injuries increased and brings great disaster to the enterprise. Hence, in order to reduce the losses to the minimum on the staff, property and environment caused by the accidents, it is necessary for us to take emergency measures and contingency approaches. It is necessary and essential to establish an emergency rescue system to control the coal mine accidents effectively.The main task of this dissertation is to develop a stable and reliable system, which applies to personnel, equipment management and search and rescue under the coal mine. The system first uses wire and wireless hybrid network with architecture of distribution and two levels domestic, including control console in the ground, communications interface, underground monitoring substations, wireless signal receive-transmitted sensors and signal transmitter. The signal receive-transmitted sensors can cover any place of the underground, so we can accurately locate the position of the staff or the equipment. When the worker enters the underground mine and just passes or closes with any signal transceivers, the transceivers will immediately know and upload to the monitoring console in the control center as soon as possible. At the same time, the computer can immediately determine specific information, which shows with the big screen in the control center or in the computer, then stores the data. The system can also be linked to the computer in the control center of the ground through network cabling.
