Conveyer belt operation monitoring system and method

Abstract

The invention relates to a conveyer belt operation monitoring system and method. The conveyer belt operation monitoring system comprises a data processing module, a voltage converting and detecting module, a vibration sensor, a temperature sensor, a displacement sensor, a wireless communication module and an upper computer, wherein the voltage converting and detecting module is used for monitoring a pull switch; a single-chip microcomputer is used for reading a voltage outputted by a voltage converting circuit, performing A / D conversion, performing packing and performing encapsulating; the wireless communication module is used for sending the packed and encapsulated voltage data to the upper computer; the vibration sensor is used for acquiring vibrating data of a gear box; the temperature sensor is used for acquiring temperature data of the gear box; and the displacement sensor is used for acquiring the axial displacement offset of a conveyer belt roller. Through the adoption of the conveyer belt operation monitoring system and method disclosed by the invention, the comprehensive real-time accurate monitoring of the operation state of the conveyer belt system can be realized, so that the problems that a conveyer belt pull switch are difficult to detect and position in a flash manner are solved, and the functions of prejudging failure trend of the gear box, warning abnormal situations, warning the situation that shaft scurrying is generated on a driving roller are realized.

Description

technical field [0001] The invention belongs to the field of intelligent monitoring, in particular to a belt conveyor operation monitoring system and a method thereof. Background technique [0002] The belt conveyor uses the continuous or intermittent movement of the conveyor belt to transport various items of different weights. It can transport various bulk materials and complete goods, especially in ports and wharves. As an important protection device of the belt conveyor, the pull switch of the belt conveyor is connected in series. Once the pull switch flashes off, it will cause the belt conveyor to stop frequently. Moreover, since the length of the belt conveyor is measured in kilometers, it is very difficult to find the fault and it is easy to occur. Safety accidents, the consequences are unimaginable, and even cause belt tearing, personal injury and death accidents; as a power transmission device, the belt conveyor gearbox is difficult to overhaul due to harsh working ...

Problems solved by technology

As an important protection device of the belt conveyor, the pull switch of the belt conveyor is connected in series. Once the pull switch flashes off, it will cause the belt conveyor to stop frequently. Moreover, since the length of the belt conveyor is measured in kilometers, it is very difficult to find the fault and it is easy to occur. Safety accidents, the consequences are unimaginable, and even cause belt tearing, personal injury and death accidents; as a power transmission device, the belt conveyor gearbox is difficult to overhaul due to harsh working environment, heavy load, and long running time, resulting in gears, drive shafts and bearings. Various failures occur, such as tooth profile error, gear wear, broken teeth, shaft imbalance, bearing fatigue peeling and pitting, etc. At the same time, the temperature of the gearbox is too high, which reduces the lubrication effect of the components and further aggravates the failure To a certain extent, once a failure occurs, it will cause the equipment to stop and bring huge economic losses to the enterprise; the belt conveyor pulley is an important part of the direct output force in the belt conveyor drive device, and it contacts with the belt to drive the belt conveyor to run through friction. Long running time, excessive load, or uneven coal loading and belt deviation will cause occasional shaft shifting of the drum. Once the shaft of the drum shifts, it will further worsen the deviation of the belt, and even cause serious accidents such as belt tearing. It affects the normal operation of other driving devices of the belt conveyor, causing the paralysis of the entire operation process and causing great losses to production

In the prior art, there is no system or method for comprehensively monitoring the running status of the belt conveyor
