Embodiment Construction

[0022] An embedded mining data substation based on an ARM processor of the present invention is an underground data acquisition and control device used in a coal mine safety production monitoring system. The device is composed of intrinsically safe power supply, ARM controller main board, CAN bus communication board, display driver board, LCD screen and explosion-proof casing, such as figure 1 shown. The explosion-proof enclosure is composed of an explosion-proof chamber and an intrinsically safe chamber. The intrinsically safe power supply is installed in the explosion-proof chamber. The ARM controller main board, CAN bus communication board, display driver board and LCD display are all designed with intrinsically safe circuits. The 104-core system bus interface is designed according to the same bus standard on the circuit board, and the bus-type plug-ins are used to stack and insert each other, and are installed in the intrinsically safe chamber; the explosion-proof chamber ...

Abstract

The invention discloses an embedded mine data substation which is an underground data acquisition and control device used in a coal mine safe production monitoring system. The substation comprises an intrinsic safety power source, an ARM controller mainboard, a CAN bus communication board, a display drive board, a liquid crystal display screen and an explosion-resistant enclosure. Real-time data of various sensors of analog quantity, switching value and cumulant, which are articulated with the mine data substation, is acquired in real time through a downlink RS485 bus, and the real-time data is displayed by the liquid crystal display screen; cutting off control is automatically performed to articulated output equipment by means of set control logic according to the change of the real-time data; the data is transmitted to a ground monitoring host computer through an uplink CAN bus interface and network monitoring is performed. The substation is suitable for underground environment of a coal mine, has functions of intelligent alarm, cutting off control and automatic network deployment, is an important component element in a masterless coal mine safe production monitoring system and can reduce the occurrence probability of coal mine safety accidents in time.

Description

technical field [0001] The invention relates to the field of information processing technology in the field of information technology and automation, and relates to the functional composition of the underground monitoring data substation in the real-time monitoring and monitoring system for underground safety production in coal mines. The monitoring and monitoring device has formed a mining monitoring equipment suitable for the underground environment of coal mines with intelligent alarm power-off control and autonomous networking functions. Background technique [0002] The energy industry is a crucial basic industry for the sustained and rapid development of the national economy and national defense construction. Coal resources are the most important energy component in our country, and the domestic coal production industry is also one of the country's important pillar industries. The coal safety production monitoring system is an indispensable part in the process of ensur...
