Embodiment 1
[0036] In the existing technology, if the gate area is not completely closed, there may be some safety hazards in the surrounding environment when the gate is running: 1. Hoist machine room: when the gate is operated on-site, automatically and remotely, if the on-site staff During maintenance, cleaning and other operations, the on-site staff cannot be notified in a timely and effective manner, which may cause safety problems. 2. For projects where the management area is open, people may engage in illegal fishing, fishing and other activities near the gate, and even dangerous behaviors such as jumping over the gate may occur, posing a major safety hazard. Therefore, the present invention proposes a wireless acousto-optic early warning system for gate operation, which can greatly improve the safety performance of gate automation control and provide technical support for the safe use of the gate intelligent management and control system.

Embodiment 2
[0049] Such as Figure 2-3 As shown, the difference between this embodiment and Embodiment 1 is that the signal collector includes a test tooth plate 2, a trigger block 4 connected to the test tooth plate 2, and at least two proximity switches 6 for sensing the position of the trigger block 4 ;
[0050] The center of rotation of the test chainring 2 is hinged to the traverse bracket 3, the traverse bracket 3 can slide laterally relative to the vertical guide rail 1, and the other end is provided with a proximity switch bracket 5, and the proximity switch 6 is installed on the proximity switch 6. switch bracket 5;
[0051] The traversing bracket 3 is also connected to the cylinder 7 for driving the traversing bracket 3 to slide laterally relative to the vertical guide rail 1, and to realize the combination or disengagement of the test tooth 21 and the guide rail rack 11;
[0052] A tension spring 41 for making the induction trigger block 4 in the middle position is also provi...
