Problems solved by technology

Especially in recent years, with the continuous deepening of the government's urbanization reform and the rise of high-rise and super high-rise buildings, tower cranes have played an increasingly important role in the construction process of modern buildings, and they are constantly developing in the direction of large-scale and intelligent. Among them, casualties and equipment damage caused by tower crane accidents occur frequently, and the incidence of major accidents remains high. The safety performance of tower cranes has become a public safety issue that threatens the lives of construction workers and corporate property. How to ensure the safety of the tower crane during operation is a major problem to be solved urgently due to the complexity of the construction environment, such as obstacles in the work area and numerous personnel.

[0003] There are many reasons for tower crane accidents; one of them is that the tower crane operators do not know the current state of the tower crane, and blind operation leads to accidents; on the other hand, some tower crane operators cause the tower crane to Overload work and illegal operations occur from time to time. At the same time, construction site security personnel, engineering supervision departments, safety supervision departments, etc. cannot keep abreast of the real-time status of the tower cranes on the entire construction site. The supervision is difficult and the monitoring is weak, which is also the reason for the tower crane operators to operate illegally. Therefore It is urgent to study the online monitoring of the real-time operation status of the tower crane

[0004] At present, some simple control instruments assembled by domestic tower cranes can only monitor the torque, weight, amplitude and other information of the tower crane, and do not have the functions of stand-alone anti-collision, group anti-collision, real-time remote monitoring and video supervision, real-time monitoring and video supervision on the construction site, traditional The technical level cannot accept the cost of microwave transmission of video signals, let alone effectively realize wireless high-speed transmission of video signals. We focus on the innovation of 4G wireless mobile network and short-range microwave wireless communication technology, based on the high-speed communication technology of 4G wireless mobile network , making real-time remote video monitoring of construction sites possible, which was difficult to achieve in the past. At the same time, the innovation of short-range microwave wireless communication technology enables local multi-directional network video monitoring, and realizes real-time tower crane operation status monitoring and monitoring on site. Real-time video surveillance on the construction site; combined with the installation of sensors on the tower crane that can collect various physical parameters during the operation of the tower crane, it is judged whether the collected physical parameters exceed the preset range, thereby limiting the operation of the tower crane, realizing human-computer interaction, and facilitating tower crane operators to obtain Parameters of tower crane operation

[0005] In addition, the layout density of tower cranes on large construction sites is increasing, and the frequency of collisions between tower cranes and tower cranes with surrounding buildings is also increasing. Lack of supervision and accidents may occur at any time; in order to facilitate construction engineering companies , engineering supervision department, safety supervision department, and construction security inspection personnel can monitor the real-time operation status of the tower crane and the real-time information of the construction site at any time, and design a 4G wireless network communication, which can view the live situation on the site, has strong data processing capabilities, and has multiple Measurement and control tasks, safe and reliable, easy to operate, can prevent the tower cranes from colliding with each other when the tower cranes are interfering with each other, and have a tower crane monitoring system that can remotely monitor the operating status of the tower cranes and real-time on-site events.
