Problems solved by technology

[0003] In the traditional tower crane safety monitoring instruments, video monitoring is often used, and the staff monitors the status of the tower crane through video. This video monitoring method has poor real-time performance, slow data processing, short transmission distance, and cannot be composed. The monitoring network has the disadvantages of unified management. At the same time, the monitoring circuit is limited to the stand-alone version of the monitoring circuit or the small-scale tower crane group control monitoring circuit, which has the disadvantages of small monitoring range and inconvenient management.
This brings great inconvenience to the cause analysis of tower crane accidents and background data management
Moreover, this monitoring method requires staff to be on duty at all times. At the same time, once the staff is negligent or absent, safety accidents are prone to occur.

Description

technical field [0001] The invention relates to a tower crane safety monitoring circuit provided with a GPRS module. Background technique [0002] Tower crane (towercrane) referred to as tower crane, also known as tower crane, consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower body, the boom and the base, etc. The working mechanism has four parts: lifting, luffing, slewing and walking. The electrical system includes motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices, etc. With the extensive use of tower cranes in the construction industry in recent years, various tower crane operation safety accidents have occurred frequently due to violations of regulations and overruns of tower cranes and interference and collisions of tower crane groups, resulting in huge losses of life and property. The experience and lessons of safety accidents show that it is necessar...
