The invention relates to an embedded mine data substation, which is a downhole data acquisition and control device used in a coal mine safety production monitoring system. The station is made by ARM, intrinsically safe power supply controller board, CAN bus communication boards, display driver board, LCD screen and explosion-proof casing. The real-time data collected in real-time downlink RS485 bus connected to the mine data substation on various analog and switch quantity, the accumulation of the sensor, through the LCD display; according to the real-time data changes, according to the control logic set automatically for hanging the output device through the uplink power control; CAN bus interface data transfer to the ground monitoring host, network monitoring. The station is suitable for coal mine environment, intelligent alarm power-off control and independent networking functions, is an important part of the type of coal mine production safety monitoring system, can reduce the probability of the occurrence of coal mine safety accidents in a timely manner.
