System and method for remote fault diagnosis of conveying belt

Abstract

The invention provides a method for the remote fault diagnosis of a conveying belt. The method comprises the steps: monitoring the operating status of the conveying belt by using a signal acquiring and monitoring device, and acquiring an operating status signal of the conveying belt; receiving the operating status signal by a programmable logic controller which controls the operation of the conveying belt, and diagnosing whether the conveying belt is in a fault or not according to the operating status signal; if a diagnostic result shows that the conveying belt is in the fault, triggering an alarm signal corresponding to the fault; receiving the alarm signal by a monitoring computer, and extracting corresponding alarm information from a pre-prepared alarm information database according to the alarm signal, wherein the alarm information comprises the location and reason of the fault; displaying the alarm information on the monitoring computer. The invention further provides a system for the remote fault diagnosis of the conveying belt. By using the method and the system, the fault of the conveying belt can be diagnosed remotely, so as to avoid the influence on paper roll production.

Description

technical field [0001] The invention relates to a papermaking process, in particular to a remote diagnosis system and method for conveyor belt faults in the papermaking process. Background technique [0002] In the papermaking process, the conveyor belt of the paper roll uses a programmable logic controller (programmable logic controller, PLC) as the core control unit for fault diagnosis. When the conveyor belt fails, the operator needs to go to the production site to confirm the location of the failure (that is, the point of failure) and the cause of the failure, and then call the equipment maintenance personnel to go to the production site to deal with the failure. Usually, equipment maintenance personnel can diagnose the fault point according to the operation status of the conveyor belt and deal with it accordingly. Once the equipment maintenance personnel cannot diagnose the fault with personal experience, technicians need to use a professional computer to connect PLC to...

Problems solved by technology

Usually, equipment maintenance personnel can diagnose the fault point according to the operation status of the conveyor belt and deal with it accordingly. Once the equipment maintenance personnel cannot diagnose the fault with personal experience, technicians need to use a professional computer to connect PLC to diagnose the fault point. , which leads to a long time for the diagnosis and processing of the entire fault, which affects the normal operation of the conveyor belt and causes great losses to the paper company
