When there is an irregular situation, the alarm device issues an alarm prompt to serve as a warning, thereby strengthening the real-time supervision of the safe and standardized use of safety belts by high-altitude workers and ensuring the safety of high-altitude workers.

[0032] During the use of the double-hook safety belt, at least one hook must be kept fixed at the anchor point at all times, and both hooks cannot be disassembled at the same time. However, when changing the hanging position of the hook, it is often negligent to ensure that at least one hook is hung at the anchor point, which can easily cause accidents. Based on this, the embodiment of the present application also includes a locking device 7 connected to the controller 1, Figure 3 A schematic diagram of a hook provided in an embodiment of the present application, such as Figure 3 As shown, the hook includes a hook body 16 and a locking arm 17 pivotally connected to the hook body 16, and an opening and closing mechanism connecting the hook body 16 and the locking arm 17. The opening and closing mechanism can adopt an automatic reset spring so that the locking arm 17 can automatically reset and abut against the hook body 16 without the action of external force. The locking device 7 is used to lock the locking arm 17 with the hook body 16 to prevent the locking arm 17 and the hook body 16 from being easily separated under the action of external force.

[0033] The embodiment of the present application sets a locking device 7. When the first pressure sensor 2 in a hook detects no pressure, it indicates that the hook has been removed. To prevent the other hook from being removed by the staff, the controller 1 can control the locking device 7 to lock the locking arm 17 of the hook with the hook body 16.
