ON-SITE SAFETY CONTROL METHOD FOR TOWER CRANE, CONTROLLER, AND COMPUTING DEVICE

An on-site safety control method for a tower crane, a controller, and a computing device. The control method comprises: controlling a hook to move in an axial space according to planned path points (S110), the hook reaching every two neighboring planned path points within a plurality of control periods; obtaining the current position of the hook in the axial space within each control period (S120); obtaining the current maximum allowable speed of the hook in each direction in the axial space according to current luffing length and lifting weight as well as operating parameters of the tower crane (S130); and obtaining an arrival position and a target speed of the tower crane in the axial space within a next control period according to the current coordinates and speed as well as the maximum allowable speed in each direction of the hook in the axial space, and coordinates of the planned path point which is not reached (S140). According to the on-site safety control method, the current maximum allowable speed in
