Safety monitoring substation for coal mine

Abstract

The invention discloses a safety monitoring substation for a coal mine. The safety monitoring substation comprises an ARM central processor, as well as a keyboard input unit, an analog value input unit, a switching value input unit and an ISP programmatic interface which are connected with the input terminal of the ARM central processor through interface circuits, and a switching value output unit, an LCD unit, a power supply monitoring control unit and communication units, which are connected with the output terminal of the ARM central processor through interface circuits, wherein the communication units are two mutually independent communication systems, namely an RS485-1 communication unit and an RS485-2 communication unit which are respectively in communication connection with an upper computer and 20 lower bus sensors; the ARM central processor is connected with an intrinsic safety DC power supply through a motherboard power supply unit; the analog value input unit is connected with the analog value ports of 8 analog sensors; data of the analog value sensors are automatically calculated through the central processor. The safety monitoring substation is low in power consumption, realizes running monitoring of the 28 sensors and guarantees the safety production of the coal mine.

Description

technical field [0001] The invention relates to the field of mine monitoring equipment, in particular to a coal mine safety monitoring substation. Background technique [0002] Mine safety monitoring and monitoring system is an important measure that people must take to prevent mine gas, coal dust, and fire accidents, improve mine safety production conditions, and realize mine safety production according to the laws of mine natural disasters. Monitoring The monitoring substation is the core of the safety monitoring monitoring system. Its response speed, accuracy, safety and reliability determine the performance of the monitoring and monitoring system. [0003] At present, the monitoring and monitoring sub-stations on the market have problems such as incomplete detection types, low measurement accuracy, and poor communication reliability. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the present invention provides a coal mine...
