Description

Technical Field

[0001] The present invention relates to the field of remote control technology, and in particular to a remote intelligent centralized control system for a tower crane based on 5G communication used in construction. Background Art

[0002] With the rapid development of the construction industry, tower cranes (abbreviated as tower cranes) as important lifting equipment play an important role in construction. However, traditional tower crane operations rely on on-site personnel, which poses safety hazards and low efficiency. Due to high-altitude operations and a large working range, tower crane drivers often cannot see the situation of the hook clearly. During the construction process, there may even be a situation where the crane is across the mountain. At this time, a video solution can be used to solve the visualization problem of the tower crane driver. Since the tower crane hook moves with the tower crane trolley, the video camera can be installed on the tower crane's luffing trolley, and the camera is facing the hook below, so as to ensure that the video follows the hook. Due to the reciprocating movement of the tower crane trolley, the camera installed on the trolley is powered by the battery on the trolley, and the image is transmitted to the tower crane cockpit through a wireless bridge. In this case, the battery installed on the luffing trolley can be charged by solar energy, but the cost is too high, and the solar panels installed on the tower crane are easily damaged; another method is to use a mechanical charging device, which is low-cost and not affected by weather, but due to the different structures of tower cranes, the installation of the charging device becomes a thorny problem. The existing charging device installation structure has poor flexibility and cannot adapt to the installation of different tower crane structures. In addition, the installation location requirements are high, the operation is inconvenient, and there are certain safety hazards. In order to improve the safety and efficiency of tower crane operation, the present invention proposes a remote tower crane intelligent centralized control system based on 5G communication technology.
