Abstract

The invention provides a tower crane fault diagnosis system comprising a PC controller, , a PLC, a cloud server, a working condition information acquisition sensor and a tower crane operation information acquisition sensor. The working condition information acquisition sensor and the tower crane operation information acquisition sensor are connected with the PLC, the PLC is in communication connection with the cloud server through a wireless communication module, and the PLC is connected with the cloud server through a TCP / IP protocol; meanwhile, a model corresponding to the tower crane is arranged in the cloud server. When the system works, the cloud server inputs working condition information parameters into the corresponding tower crane model for analogue simulation and obtains corresponding simulation operation parameters, the simulation operation parameters are compared with the actual operation parameters and the working state of the tower crane is judged and the corresponding diagnosis result is sent to the PC terminal and the operator of the specific PLC so that the working state of the tower crane is monitored in real time, the difficulty of tower crane fault judgment is reduced and the fault judgment efficiency is also improved.

Description

technical field [0001] The invention relates to the technical field of crane diagnosis equipment, in particular to a tower crane fault diagnosis system. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as "tower crane". Into the building, it is an essential equipment on the construction site. In the prior art, in order to improve the safety and work efficiency of the tower crane, various intelligent sensors are continuously installed on the tower crane. While continuously improving the safety and work efficiency of the tower crane, with the continuous increase of equipment, for The later inspection and maintenance have caused great pressure, and the manual detection and fault diagnosis methods in the existing technology are becoming more and more unsuitable. Therefore, improving the fault diagnosis efficiency of tower cranes is the key to improving the working efficiency of tower cranes. Contents of th...
