System composition

The tower crane anti-collision system consists of the system host, a liquid crystal display, a BYPASS key, a range sensor, a rotation sensor, a wireless communication module, a wireless communication antenna, and a GPRS communication module.

The anti-collision system for tower cranes operates by collecting information through sensors installed on the crane boom and other locations, using radio transmitters to send the data to the receiving end, and then calculating the relative positions and movement of the cranes with software. It can automatically issue alerts or control signals when the crane approaches a dangerous position, assisting operators in safe operation and preventing accidents, as well as improving construction efficiency. The specific process is as follows: when two tower cranes may collide within the intersecting rotating radius, an alarm device in the crane cabin will emit a beep to alert the tower driver. If the driver fails to take action and continues to operate, the system will automatically lower the lever from a high gear to a low gear, eventually stopping the rotation of the crane's boom. During crane operation, signal data transmission displays the horizontal position of the crane's boom on the computer screen in the control room every 10 seconds. This system achieves real-time monitoring, automatic early warning, and risk control of the crane's operational status, reducing the likelihood of collisions; and allows safety managers to visually monitor the crane's usage without being on-site.
