Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.

Referring to fig. 1, a comprehensive security system for a gate machine includes:

In this embodiment: referring to fig. 1, the camera module transmits the video signal to the security processor module through the ethernet communication protocol.

The camera module shoots the picture of the door machine protection area and sends the picture to the security processor module.

In this embodiment: referring to fig. 1, the anti-collision sensor module transmits the object position information signal to the security processor module through serial port communication.

In this embodiment: referring to fig. 1, the anti-collision sensor module includes a radar sensor and a laser sensor.

The anti-collision sensor module is provided with a plurality of sensors, such as radar sensors, laser sensors and the like, for detecting the positions of objects, when two or more objects reach a threshold value (for example, 10 cm) away from each other, the radar sensors, the laser sensors and the like transmit signals, and the and gate sends object position information signals to the anti-collision sensor module. The position is detected by a plurality of sensors of different types and is output through the AND gate, so that the phenomenon of false alarm caused by a single sensor due to the influence of environmental factors and the like is prevented, and the accuracy of an object position signal output to the security processor module is ensured.

In this embodiment: referring to fig. 1, the security processor module transmits the security protection signal to the door PLC module through the ethernet communication protocol.

When the security processor module receives the video signal and the object position information signal, whether collision occurs in the video is judged by continuously simulating the moving track of the object position, and when the collision does not occur, a security protection signal is not sent to the gantry crane PLC module; and when the collision is judged, sending a security protection signal to the gantry crane PLC module, and controlling the gantry crane PLC module to stop working. Judging a moving track, for example, judging the simplest rear-end collision problem, wherein A, B runs on a track, the speed A is 1m/S, the speed B is 0.8m/S, the distance A, B is 0.1m, the A runs towards the B, and the contact of A, B can be known after 0.5S through judgment, so that when the running time A exceeds 0.5S, the security processor module sends a signal to the gantry crane PLC module; when the operation time of the A is less than 0.5S, the security protection processor module does not send a signal to the gantry crane PLC module; and A, B is controlled by the door machine PLC module, so that the security processor module acquires A, B movement information through information interaction between the security processor module and the door machine PLC module.

The working principle of the utility model is as follows: the camera device module collects real-time pictures of a door machine protection area, acquire video signals, send to the security protection processor module, the object distance data in the protection area is collected in real time by the anti-collision sensor module, acquire object position information signals, send to the security protection processor module, the security protection processor module is used for extracting the video signals output by the camera device module and matching with the object position information signals output by the anti-collision sensor module, generate security protection signals, send to the entrance guard PLC module, and acquire door machine PLC control object moving information, the entrance guard PLC module is used for receiving the security protection signals, and the door machine is controlled to start and stop.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
