Electric remote fault diagnosis system of tower crane

Abstract

The invention relates to an electric remote fault diagnosis system of a tower crane. The electric remote fault diagnosis system is characterized by comprising a computer terminal, a mobile phone APP,a cloud server, a wireless data transmitting module, a programmable controller, a touch screen, a frequency converter, an acousto-optic alarming machine, a circuit breaker, a relay, sensors and strokelimiters; the sensors and the stroke limiters are correspondingly installed at all positions of the tower crane; the frequency converter, the programmable controller and the touch screen communicatewith one another by virtue of a 485 bus communication technology; the programmable controller is used for acquiring signals of the frequency converter, the sensors and the stroke limiters and transmitting the signals to the touch screen and the wireless transmitting module; the wireless transmitting module realizes data interaction of the programmable controller and the cloud server and realizes short message control and short message remind functions by virtue of a GPRS wireless communication technology; and the touch screen is used for a driver to implement real-time image-text monitoring and fault diagnosis on the running state of the tower crane in a running process.

Description

technical field [0001] The invention relates to an electric remote fault diagnosis system of a tower crane. Background technique [0002] At present, the safety alarm signal of most tower cranes adopts the buzzer alarm, the form is too single, and the fault content cannot be judged. The ground management personnel have no way of knowing the real-time operation status and status of the tower crane. For some minor faults during the operation of the tower crane, if the driver does not deal with it in time and continue to run, it is likely to upgrade the minor fault to a major fault, which may damage electrical components or cause a safety accident. When the tower crane fails and needs to be repaired by a special person, the traditional alarm cannot judge the fault content. It needs professional maintenance personnel to go to the scene to judge the fault before they can know. If the construction period is longer, the impact will be more serious.

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a remote electrical fault diagnosis system for tower cranes, which has reliable performance and can accurately, quickly and automatically diagnose the electrical fault content of the tower crane through a mobile phone or computer when the tower crane fails, and remotely monitor the real-time operation of the tower crane The status system solves the problem that the fault content cannot be judged after the tower crane fails, and the fault escalation caused further losses due to the inability to know the fault content, and even poses a safety hazard, and the delay in the arrival of accessories leads to the extension of maintenance time.
