Problems solved by technology

[0005] Third, especially for long-distance belt conveyors, there are more protective devices and more resources are occupied
In addition, the alarm status of the protection device can only be fully grasped by the central control room, which is not conducive to post workers to grasp the operation status of the protection device of the belt conveyor in real time

Abstract

A protection system of a full-functional belt conveyer comprises a nose controller and a belt protection device, wherein the nose controller is arranged in the position of the nose of the belt conveyer, and includes a switching power supply, a bus interface converter, a PLC (Programmable Logic Controller) and a touch-control display screen; bus communication modules are internally fixed on switches of the belt protection device respectively, and are electrically connected with the switches in the belt protection device respectively; and all the bus communication modules are connected together through a two-wire system bus, and are connected with the PLC in the nose controller through the bus interface converter. Through the adoption of the protection system, the control wiring of the protection device is reduced, the material cost and the construction cost of a control cable are reduced, the wiring manner of the communication bus is flexible and can be freely topological, and the bus communication modules can set the address on line through software or a handheld programmer, so that the address is set simply and conveniently.

Description

technical field [0001] The invention relates to an industrial automation system, in particular to a full-function belt conveyor protection system. Background technique [0002] Belt conveyors are widely used in industrial process control companies. In order to ensure the safe operation of the belt conveyor, a series of protective devices have been developed in engineering practice. The commonly used protective devices include: emergency stop pull rope switch, deviation switch, stall sensor, longitudinal tear sensor, smoke temperature sensor, and material accumulation sensor. In the current automatic control system, these protection devices are connected with PLC separately, and protect the safe operation of the belt conveyor in a certain way. The disadvantages of this use are: [0003] First, the PLC controller needs to configure DI points for each protection device, which takes up a lot of PLC module resources. [0004] Second, the connection between the protection devi...
