Information management system of crane

Abstract

The invention discloses an information management system of a crane. The information management system of the crane comprises a crane operating system, a data recording system, a fault monitoring system, an equipment management system, a component life monitoring system and a fault diagnosing and analyzing system, wherein the component life monitoring system records the operating time of the important components of the crane in real time, monitors the relevant environments in which the components are positioned and the operating situations of the components by means of a sensing element, i.e. monitoring the operating time, the relevant environments and the operating situations of a contactor, a brake, a motor, a frequency converter and a voltage regulator in the crane, and acquires the residual service life of the components by carrying out difference value computing on the known service life of the components and the monitoring results; and the fault diagnosing and analyzing system is used for calling expert opinions corresponding to an event input by field staff from a database and displaying the expert opinions for the field staff through a display device. The system of the invention has strong logic control performance, high reliability and favorable compatibility and generality, and is suitable for being widely popularized in hoisting equipment.

Description

technical field [0001] The present invention relates to a crane information management system, in particular to the monitoring, protection, equipment management and fault monitoring of heavy lifting machinery such as metallurgical casting cranes, single and double girder bridge cranes, port lifting equipment, and storage yard stacking and reclaiming equipment. Judgment, track tracking and recording management system. Background technique [0002] At present, there are few professional products for logic control of crane equipment, and most of them use PLC for programming and use on site. PLC products have high environmental requirements and cannot be used in harsh environments such as high dust. Moreover, the program control logic is simple, and most of them are programmed and designed by field engineers themselves. The versatility is not high. The performance is uneven, and some places can't even meet the requirements of the scene. Especially when the components in the li...

PLC products have high environmental requirements and cannot be used in harsh environments such as high dust. Moreover, the program control logic is simple, and most of them are programmed and designed by field engineers themselves. The versatility is not high. The performance is uneven, and some places can't even meet the requirements of the site

Especially when the components in the lifting equipment are aging to the end of their service life, there will be failures at any time, and such failures are often very fatal, so the general crane equipment needs to be overhauled after running for a certain period of time. Engineers replace parts based on experience. Because of experience, there are errors. What should be replaced is not replaced. Without very experienced engineers, fault repair is a very time-consuming and laborious work
