Embedded mine data substation

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...

AI Technical Summary

Problems solved by technology

The entire monitoring process is composed of multiple communication links, and the control process is redundant and cumbersome. Coupled with the limitation of sub-station software and hardware technical conditions, a long time lag is formed from the discovery of abnormalities to the power-off operation, resulting in safety accidents serious hidden danger

In this system, the underground monitoring substation only plays the role of a data collection and communication intermediary, without autonomy and intelligence, and the control operation is heavily dependent on the communication process. Once the communication channel fails, the entire monitoring system will be paralyzed and lost. The role of safety production monitoring
