105. And the construction site server sends a second safety instruction to the mobile terminal according to the distance between the position of the worker and the second safety area, and the second safety instruction is used for reminding the worker that the second safety area is forbidden to enter.
In a preferred embodiment, referring to fig. 2, the determining, by the worksite server of step 102, the first safe area according to the tower crane position may further be:
201. and setting the position of the tower crane swing arm for lifting the weight on the site of the construction site as a starting position.
Specifically, an angle sensor is additionally arranged at the tower crane terminal, an initial zero point of the angle sensor is arranged in the extending direction of the tower crane swing arm when the weight is lifted, and the angle sensor sends the initial zero point to a construction site server.
202. And setting the position of the tower crane swing arm for laying the heavy object on the site as the end position.
Specifically, when the tower crane rotates, the angle sensor counts, and when the tower crane stays at a place for a long time to release a heavy object, the angle sensor sends the rotated angle of the tower crane to the construction site server.
203. The fan-shaped area formed by swinging the swing arm of the tower crane from the initial position to the final position is set as a first safety area, and the radius of the first safety area is the length of the swing arm.
