The main face recognition camera and the standby face recognition camera are used for face recognition and are conventional cameras special for face detection and recognition. The main crossing image monitoring camera and the standby crossing image monitoring camera are conventional image monitoring cameras used for acquiring images in corresponding areas. It should be understood that the main and backup face recognition cameras are cameras dedicated to face detection and recognition, while the main and backup crossing image surveillance cameras are conventional image surveillance cameras. Moreover, the main face recognition camera, the standby face recognition camera, the main road junction image monitoring camera and the standby road junction image monitoring camera can be fixed on a fixing rod specially arranged at the position of a mine area railway junction, and the setting height is set by actual needs. The four cameras are all arranged towards the railway crossing of the mining area.
The first switch T1 and the second switch T2 are both conventional alternative switches, and both have a movable end, a first immovable end and a second immovable end, so as to realize the communication between the movable end and the first immovable end, or the communication between the movable end and the second immovable end. The first switch T1 and the second switch T2 may be manually operated switches or electrically controlled switches, and are controlled by control signals.
The dangerous gas concentration sensor is used for detecting the concentration of dangerous gas at the position of a mine area railway crossing. Because gas leakage is easy to occur in the process of digging the mine, in the embodiment, the dangerous gas concentration sensor is a gas concentration sensor.

The GPRS wireless communication device may be a conventional GPRS wireless communication device. Since the communication signal strength in some mining areas is relatively weak, in this embodiment, the GPRS wireless communication apparatus includes a signal booster and a GPRS antenna. The signal intensifier can intensify the intensity of the communication signal and improve the reliability of GPRS communication.
The first switch T1, the second switch T2, the control host and the GPRS wireless communication device may be provided in a control box fixed to the fixing lever as described above.

The control host transmits the received data information to the background monitoring center through the GPRS wireless communication device, so that effective monitoring of the railway crossing of the mining area is realized. Moreover, when the main face recognition camera has a fault, for example, the background monitoring center finds that the main face recognition camera does not normally return an image any more, the main face recognition camera is switched to the standby face recognition camera through the first switch T1, and the standby face recognition camera is put into use, so that the face recognition monitoring is continuously realized. When the image monitoring camera of the main road junction is in fault, for example, the background monitoring center finds that the image monitoring camera of the main road junction does not normally return images any more, the image monitoring camera of the main road junction is switched to the image monitoring camera of the standby road junction through the second switch T2, and the image monitoring is continuously realized by switching the image monitoring camera of the main road junction to the image monitoring camera of the standby road junction.
In this embodiment, the first switch T1 and the second switch T2 are both electrically controlled switches, such as contact switches of a relay, and the switching control of the first switch T1 and the second switch T2 is realized by controlling the power-on state of a control coil of the relay.

And, output the high level signal after the identity is verified, output the low level signal when the identity is verified and failed or the authentication device is in idle state.
The first and logic operation circuit and the second and logic operation circuit are both conventional and logic operation circuits, and both comprise two signal input ends, and for any one of the and logic operation circuits, the and logic operation circuit outputs a high-level signal only when the two signal input ends input a high-level signal.

And the signal output end of the identity authentication device is connected with the second signal input end of the first AND logic operation circuit and the second signal input end of the second AND logic operation circuit. Therefore, only when the identity authentication device passes the identity authentication of the related personnel and the first switching control button is pressed, the first AND logic operation circuit outputs a high level signal; the second AND logic operation circuit outputs a high level signal only when the identity authentication device passes the identity authentication of the relevant person and the second switching control button is pressed. Through the authentication and the logic control of the switching control button, the switching safety of the camera is improved, and the random operation of irrelevant personnel is prevented.
