Optical fiber passive conveyor comprehensive protection system

Abstract

The invention discloses an optical fiber passive conveyor comprehensive protection system and belongs to the technical field of conveyors, the optical fiber passive conveyor comprehensive protection system comprises an optical fiber passive conveyor comprehensive protection control box, an optical fiber comprehensive distribution box and an optical fiber passive sensor, the optical fiber passive conveyor comprehensive protection control box is connected with the optical fiber passive sensor through the optical fiber comprehensive distribution box. The optical fiber passive sensor comprises an optical fiber passive pull rope locking switch, an optical fiber passive deviation sensor, an optical fiber passive blockage sensor, an optical fiber passive material flow sensor, an optical fiber passive speed measurement sensor, an optical fiber passive temperature sensor and an optical fiber passive strip tearing sensor. Continuous and real-time monitoring and optical fiber data acquisition are carried out through an optical fiber grating sensor, different external optical fiber interference types are judged through back-end analysis processing and intelligent identification, and system early warning or real-time warning is achieved, so that the purpose of comprehensive protection of a belt conveyor is achieved.

Description

technical field [0001] The invention relates to the technical field of conveyors, in particular to a comprehensive protection system for optical fiber passive conveyors. Background technique [0002] Belt conveyors, also known as belt conveyors, are widely used in various industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, food, etc., for the assembly, testing, debugging, packaging and transportation of objects. At present, the sensors used in the online monitoring system for comprehensive protection status of belt conveyors are all electrical signal sensors, which require address encoders, repeaters, signal terminals and power supply, so that the system has: [0003] 1. Long-distance fixed-point communication and power supply for sensors along the line are required; [0004] 2. It is easily affected by the external environment, the transmission is unstable, the transmission ef...

AI Technical Summary

Problems solved by technology

[0003] 1. Long-distance fixed-point communication and power supply for sensors along the line are required;

[0004] 2. It is easily affected by the external environment, the transmission is unstable, the transmission efficiency is low, and regular maintenance is required;

[0005] 3. The electrical signal sensor is prone to drift, and it needs to be corrected before use to ensure the accuracy of the transmitted signal, and the operation is reliable and stable;

[0006] 4. The sensor connection needs to be connected with one line, and the signal monitoring also needs to be connected with one line.
