Power line carrier/NB-IOT composite communication mine electromechanical equipment management and control system

Abstract

A power line carrier / NB-IOT composite communication mine electromechanical equipment management and control system comprises electromechanical equipment, a power distribution cabinet, a control switch, a power line carrier communication module, an NB-IOT communication module, a local controller, a carrier power wire, a control host, a management and control platform, a mobile terminal, a monitor and a power bus. The system is characterized in that the electromechanical equipment is mounted at an underground fixed position; an electromechanical equipment power line is connected with the power output end of the alternating current contactor of the control switch; the power input end of the alternating current contactor of the control switch is connected with the sending coupling controller of the power line carrier communication module; the sending coupling controller is connected with a carrier power wire and transmits power and monitoring information through the carrier power wire, andthe other end of the carrier power wire is connected with a power bus sequentially through a power carrier module receiver coupling controller, the local controller and a closing switch on the powerdistribution cabinet side to form a power loop of electromechanical equipment; and the local controller is also in circuit connection with the NB-IOT communication module, and the local controller andthe NB-IOT communication module perform bidirectional signal feedback.

Description

technical field [0001] The invention relates to the field of operation and maintenance of mine electromechanical operating equipment, in particular to a power carrier / NB-IOT composite communication mine electromechanical equipment management and control system. Background technique [0002] As the infrastructure of coal mine production, electromechanical equipment is a prerequisite for realizing high-quality, high-yield, low-consumption and high-efficiency coal mines. It runs through all aspects of mine production. Coal mine electromechanical equipment consists of mining electromechanical equipment, safety electromechanical equipment and related electrical systems. The equipment belongs to heavy mechanical equipment, which is generally bulky, highly mechanized, high in price and strong in automatic replacement. Safety equipment such as explosion-proof, ventilation, fire prevention, oxygen supply and other equipment are small in size, flexible in use, and low in automation. M...

However, due to the complex underground terrain and harsh environment, the location of the equipment is constantly changing with the mining progress. Using the existing wireless Internet of Things communication, it is difficult to achieve stable due to roadway barriers, high temperature and high humidity, and electromagnetic interference the monitoring effect; the use of wired communication is time-consuming, labor-intensive and costly, and it is impossible to lay signal lines to every corner of the roadway, which is also unrealistic
