Fault online diagnosis distributed tower crane electric control system and equipment, and storage medium

Abstract

The embodiment of the invention provides a fault online diagnosis distributed tower crane electric control system and equipment. The system comprises a tower crane control module, a calculation diagnosis module, a display and debugging module, a communication module and a distributed IO control module, wherein the tower crane control module is connected with an industrial bus and is used for carrying out logical judgment and sending a control command; the calculation diagnosis module is connected with the industrial bus and is used for calculating monitoring data, diagnosing a fault message and sending the fault message obtained through diagnosis out; the display and debugging module is connected with the industrial bus and is used for carrying out interface debugging, status display and parameter input of the tower crane control module; the communication module is connected with the industrial bus and is used for interacting information with a cloud control center, providing related information and establishing communication connection with external equipment; and the distributed IO control module is connected with the industrial bus and is used for collecting the status signal ofan external mechanism, collecting the actuating signal and the running status signal of devices in a cabinet, and interacting the collected signals with the tower crane control module. The system canrealize fault monitoring to all tower crane equipment.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of distributed tower crane detection, and in particular to an electric control system, equipment and storage medium of a distributed tower crane for online fault diagnosis. Background technique [0002] At present, the electronic control system of tower cranes (hereinafter referred to as: tower cranes) in the domestic market rarely implements comprehensive fault monitoring for each component of the tower crane. Generally, the fault monitoring of tower cranes often uses a third-party online monitoring system to monitor specific equipment. The monitoring is not comprehensive enough, and the fault diagnosis is vague. The third-party monitoring system and the tower crane control system are arranged independently, and are responsible for collecting sensor signals and performing centralized processing. The third-party monitoring system is also connected with the tower crane controller thr...

AI Technical Summary

Problems solved by technology

This requires centralized collection and processing of signals, and external cables need to be concentrated in a cabinet, resulting in complex wiring, long signal lines outside the cabinet, and easy signal detection errors or malfunctions due to cable damage

If a comprehensive fault detection is performed on the tower crane, a large number of signal feedbacks are required, and it is difficult to provide a large number of IO interfaces for relevant fault detection methods, so fault monitoring can only be performed on relatively more important equipment

The control system of the tower crane relies on mechanical limit switches. When the mechanical limit switches are polluted, aged or in a state of vibration, they are prone to misoperation and insensitivity, and related technologies cannot diagnose whether the limiter is faulty. , there is a security risk
