Optical fiber passive conveyor comprehensive protection system

Abstract

The invention discloses a comprehensive protection system for an optical fiber passive conveyor in the technical field of conveyors, including an integrated protection control box for an optical fiber passive conveyor, an optical fiber integrated splitting box and an optical fiber passive sensor. The control box is connected with the optical fiber passive sensor through the optical fiber integrated fiber distribution box. Optical fiber passive material flow sensor, optical fiber passive speed sensor, optical fiber passive temperature sensor, optical fiber passive tear tape sensor, through the optical fiber grating sensor, continuous and real-time monitoring, optical fiber data collection, after back-end analysis Processing and intelligent identification, judging different types of external optical fiber interference, realizing system early warning or real-time alarm, so as to achieve the purpose of comprehensive protection for belt conveyors.

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.
