With the vigorous development of the domestic real estate industry, more and more construction sites, architectural styles and heights have also increased, tower cranes have been widely used in the construction industry by using their vertical transportation capacity. The vigorous development of a thing will inevitably face various problems on the road of development, and tower cranes are no exception, with rapid development and frequent accidents.
Problems faced
1. Working at height, the lifting weight is too large, and the crane driver cannot find it in time
2. The operation of the tower crane driver is not standardized
3. Lack of security protection mechanism, when there is a problem can not be found in time
solution
Tower crane wireless safety management system, mainly composed of high-definition cameras and 4G industrial DTUs and 4G/5G industrial routers, high-definition cameras mainly monitor the operation specifications of operators, as well as the work situation on site. High-definition camera through the 4G / 5G industrial router connection, timely construction site and staff monitoring images uploaded to the cloud management platform, dispatching center through video analysis, timely discovery of problems to solve problems, through the 4G industrial DTU to the tower crane when working, lifting ratio monitoring and calculation, for the set of good data comparison, once the monitoring has exceeded the early warning value, the system will carry out alarm. Then through the 4G industrial DTU automatically stop the continuation of the operation, and through the system as much as possible to avoid negligence or mistakes, resulting in serious safety accidents, but also greatly ensure the safe use of the tower crane. At the same time, the data upload through the 4G/5G industrial router also provides a reliable basis for the analysis and processing of the accident.

System advantages
The use of 1.4G industrial DTUs allows timely reminders of illegal operations, and the early warning mechanism improves safety awareness and greatly eliminates potential safety hazards
The use of 2.4G/5G industrial routers allows data to be updated and saved in a timely manner, so that the construction unit can better eliminate hidden dangers
3. Through the combination of high-definition cameras and 4G/5G industrial routers, the problem of manual inability to monitor safe production in time is completely solved, and the illegal operations can be grasped in time and reminders can be given
4. For tower crane suppliers, they can understand the operating status of tower cranes in a more timely manner, better repair and maintenance of tower cranes in a timely manner, and troubleshoot and eliminate faults
5. If you use the Mobile Unicom Telecom Internet of Things card (SIM card), you can make the high-altitude signal better and more stable, and the best protection for workers and enterprises
