Belt conveyor monitoring system based on Ethernet

Abstract

The invention discloses a belt conveyor monitoring system based on the Ethernet. The belt conveyor monitoring system based on the Ethernet is characterized by comprising a monitoring host, a monitoring terminal, an optical fiber communication ring network, a series sensor, a switching value control device, a motor frequency conversion control device, a video monitoring probe and an internet telephone terminal; the monitoring host is a monitoring and control center of the belt conveyor monitoring system; the monitoring terminal completes collection of state information and field environment information of a belt conveyor; the optical fiber communication ring network is a double-ring network; the series sensor is arranged along a conveying belt and is used for detecting the environment information of the conveying belt and monitoring the work state of the conveying belt in real time; and the switching value control device gives out an alarm when the belt conveyor breaks down or running state problems are found and controls corresponding equipment to act or be shut down. The motor frequency conversion control device, the video monitoring probe and the network telephone terminal achieve corresponding functions. A comprehensive monitoring method is provided for monitoring of the belt conveyor.

Description

technical field [0001] The invention belongs to the technical field of mining equipment fault monitoring and control, and in particular relates to an Ethernet-based belt conveyor monitoring system. Background technique [0002] Belt conveyor, also known as belt conveyor or belt conveyor, is a friction-driven machine that transports materials in a continuous manner. It is mainly composed of frame, conveyor belt, idler roller, roller, tensioning device, transmission device, etc. At present, the belt conveyor is the most widely used continuous transportation equipment in coal mine underground and surface production systems. It has strong transportation capacity, small working resistance, low power consumption, long transportation distance, long service life, low noise, safety and reliability, etc. advantage. With the emergence of high-yield and high-efficiency mines in our country, it is necessary to develop in the direction of large-scale, that is, multi-stage operation, long...

Problems solved by technology

On the one hand, in terms of function, the detection function is not complete, the existing monitoring system cannot monitor vibration and motor current in real time, and the reliability of the detection data is poor, and the detection equipment is prone to failure; the control function can only realize the start and stop of the motor or soft start control, and cannot realize The coal flow is controlled by frequency conversion; the lack of video monitoring probes makes it impossible to monitor the key parts of the belt conveyor; the telephone terminals ar
