Power line type field bus belt conveyor running speed monitoring system

Abstract

The invention discloses a power line type field bus belt conveyor running speed monitoring system, which comprises a power supply system, a main programmable logic controller (PLC) control system, a plurality of running speed detecting and processing devices for detecting and processing the running speeds of a plurality of belt conveyors, and a remote control signal transmission system for transmitting a running speed signal detected by each running speed detecting and processing device to the main PLC control system, wherein the remote control signal transmission system comprises a main control device, a sub-control device and a cable; the main PLC control system is connected with the main control device in a communication mode or a hardwired mode; and the main control device is connected with each running speed detecting and processing device through the sub-control device and the cable. The system is low in equipment investment and operating cost, easy and convenient to install and maintain and stable in signal transmission performance, and can solve the problems of complex wiring, long cable distance, high construction difficulty and the like of the conventional belt conveyor running speed monitoring system in a thermal power plant.

Description

technical field [0001] The invention belongs to the technical field of belt conveyor running speed monitoring, in particular to a power line type field bus belt conveyor running speed monitoring system. Background technique [0002] At present, there are a large number of belt conveyors in the coal transportation system of thermal power plants. Therefore, when monitoring the working status of each belt conveyor, especially when monitoring the running speed, there are a lot of data to be monitored and the detection process is cumbersome. The traditional monitoring and control method of monitoring and controlling the running speed of the belt conveyor and the monitoring system used in conjunction with it generally have a large amount of cables, cumbersome wiring, long preset cable distances, high one-time investment costs, and long construction periods. There are many practical problems such as long construction time, difficulty in on-site construction, difficulty in system op...
