A Visualization Method of Tower Crane Hook Based on UWB Following Technology

Abstract

The invention discloses a tower crane hook visualization method based on UWB follow-up technology, which includes the following steps: installing an automatic follow-up camera device and a hook UWB label device and turning on the power respectively, and the main control boards of the two devices perform initialization functions respectively, The two devices are paired and transmit wireless positioning signals, and automatically follow the camera device to calculate the relative position coordinates of the hook UWB tag device. By comparing the distance difference between the hook UWB tag device and the horizontal anchor point and vertical anchor point, the control The two-degree-of-freedom pan-tilt rotates to realize the automatic follow-up function of the camera device in the horizontal and vertical directions. By setting the automatic following camera device and the hook UWB tag device, and using the method of UWB following and the method of two-degree-of-freedom pan-tilt control, the automatic following camera device can follow the hook of the tower crane in real time, so as to realize the visualization of the tower crane hook and serve the tower crane driver Provide full viewing angle monitoring to improve the safety of tower crane operation.

Description

technical field [0001] The invention relates to the technical field of tower crane hook visualization, in particular to a tower crane hook visualization method based on UWB following technology. Background technique [0002] Tower crane is referred to as tower crane for short. The tower crane driver needs to observe the position of the hook and the surrounding environment in real time in the cab, but due to the long distance, it is impossible to see the real-time status of the hook. Relying on the work instructions of the ground personnel to operate is easy to cause safety hazards due to poor communication. The communication between the ground personnel and the tower crane driver relying on the walkie-talkie can easily cause understanding errors and cause the tower crane driver to misuse. At present, the existing hook visualization cameras are all installed on the mobile trolley above the vertical direction of the hook, which can only provide a vertical and downward viewing ...

AI Technical Summary

Problems solved by technology

At present, the existing hook visualization cameras are all installed on the mobile trolley above the vertical direction of the hook, which can only provide a vertical and downward viewing angle above the hook for the reference of tower crane drivers. They are usually called hook visualization products. Observing the working status of the hook from the perspective, there is no effective solution at present
