Mining automatic water drainage device applying carrier wave

Abstract

The invention provides a mining automatic water drainage device applying carrier wave, and belongs to the technical field of industrial and mineral automatic measurement and control. The mining automatic water drainage device applying carrier wave is characterized in that the complete device is composed of two parts of acquisition control and carrier wave communication. The main characteristic of the device is that the device is provided with a networked control system based on electric power carrier wave communication. Real-time interaction of water regime information like the water level values of all water sumps of underground roadway and the start and stop state of water pumps is performed via the carrier wave communication mode so that remote monitoring of the underground roadway water drainage is realized. Water regime information acquisition, processing and control signal output are realized by the system through single-chip microcomputer control with no requirement for laying dedicated communication lines, and networking communication is realized in the electric power carrier wave mode so that the device has characteristics of being high in degree of automation, simple in networking and real-time and reliable in communication. The device is mainly suitable for underground roadway water drainage occasions which are severe in environment, disperse in water sump position distribution and difficult in communication wiring.

Description

technical field [0001] The invention relates to a mine automatic drainage device using a carrier wave, which belongs to the technical field of automatic measurement and control of coal mines, and in particular relates to a remote monitoring of a mine automatic drainage device based on a power carrier communication technology. The device is applied to the water level monitoring of the water accumulation point in the mine roadway and the automatic start-stop control of the water pump. It communicates through the power supply cable, which overcomes the technical problems of low automation of the mine roadway drainage device, difficulty in underground communication networking, and difficulty in realizing remote monitoring. It is suitable for the drainage of accumulated water in mine roadways with scattered water tanks and difficult communication wiring. It has the characteristics of no need to arrange special communication lines, real-time monitoring of water levels, automatic alar...

AI Technical Summary

Problems solved by technology

Stand-alone automation is mainly based on single-machine independent work, which can only realize the start-stop control of mine water pumps, cannot realize long-distance transmission of information, cannot complete real-time interaction of water regime data in underground roadway water tanks, and has no remote monitoring function; network control generally adopts The bus method connects mine drainage devices to the network to realize remote monitoring. However, due to the large number of underground drainage devices, scattered distribution, and different conditions, it causes problems such as complex wiring, high cost, inconsistent interfaces between various drainage devices, and difficult networking. , only some key important drainage devices can be networked, and it cannot completely solve the network control problem of coal mine underground drainage equipment
