[0013] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0014] In the description of this application, it should be understood that the terms "first," "second," etc., are used to distinguish similar objects, rather than to describe or indicate a specific order or sequence. The terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0015] like Figures 1-3 As shown, the mobile underground working face monitoring device based on a wireless bridge involved in this application includes a monitoring box 1, which is mounted on a triangular support 2. By moving the triangular support 2, the actual usage needs can be met, that is, the monitoring box 1 can be moved to a relevant position to collect real-time images of the working face.

[0016] The monitoring box 1 is equipped with a box cover 15, which has a safety lock. The monitoring box 1 is equipped with a camera 3 and a lens fill light 5. The lens fill light 5 is connected to the photosensitive interface of the camera 3 via a cable and is used to provide supplementary light for the camera 3. A first transparent cover 4 and a second transparent cover 6 are respectively fixed on the outer surface of the monitoring box 1. The first transparent cover 4 corresponds to the camera 3 and is used to cover the camera 3. The second transparent cover 6 corresponds to the lens fill light 5 and is used to cover the lens fill light 5. The first transparent cover 4 and the second transparent cover 6 play a sealing role to prevent dust and other objects from entering the monitoring box 1.

[0017] The monitoring enclosure 1 also houses a mining battery 7. The charging input terminal of the mining battery 7 is connected to the charging interface 10 on the monitoring enclosure 1. The mining battery 7 can be charged by an external power source. In the absence of an external power source, the monitoring device can operate continuously for more than 18 hours using the mining battery 7. The mining battery 7 can supply power to the camera 3 and the PoE splitter 9 through the wiring terminal 8. A power switch is provided on the monitoring enclosure 1. The power switch is located in the line between the mining battery 7 and the wiring terminal 8. By controlling the on / off state of the power switch, the power supply to the camera 3 and the PoE splitter 9 can be controlled. The network cable interface of the camera 3 is connected to the PoE splitter 9. The PoE splitter 9 is connected to an external wireless bridge receiver 12. The wireless bridge receiver 12 is mounted on the tripod 2 and is also powered by the mining battery 7. Specifically, the network cable interface of the camera 3 is connected to the PoE splitter 9 via an RJ45 cable. The PoE interface of the PoE splitter 9 is connected to the network cable output terminal 11 located on the monitoring box 1 via a connecting cable. The wireless bridge receiver 12 is connected to the network cable output terminal 11 via a connecting cable. The wireless bridge receiver 12 works in conjunction with the wireless bridge transmitter 13, which is connected to the PoE switch 14 via a network cable. Due to the use of wireless bridge transmission, it can be expanded by wireless cascading according to the actual situation on site (that is, adding wireless bridge pairs, i.e., wireless bridge receiver and wireless bridge transmitter). It can transmit video data in real time based on the on-site network. The straight-line transmission distance of a single cascade can reach 5km, and a maximum of 3 cascades can be made to solve the network transmission problem in scenarios with many bends and complex terrain underground.

[0018] To better seal the monitoring box 1, a sealing strip 16 is fixed on the monitoring box 1 to prevent dust and other substances from entering the monitoring box 1. This is suitable for high temperature and high humidity environments underground.

[0019] In practical use, the tripod 2 can be moved as needed, and the camera 3 can capture real-time images of the mining face. Through the PoE splitter 9, the wireless bridge receiver 12, and the wireless bridge transmitter 13, the video images of the mining operation can be transmitted in real-time to the PoE switch 14. The wireless bridge receiver 12 involved in this application interconnects with the remote wireless bridge transmitter 13 via a wireless through-beam connection, completing a simple, user-friendly network setup.

[0020] The mobile underground working face monitoring device based on a wireless bridge involved in this application can collect real-time images of the working face and realize real-time transmission of video images of the working face. It can transmit video images to the dispatch center in real time based on a wireless network, so that the working face situation can be grasped in a timely manner. The monitoring device involved in this application adopts modular installation, is easy to move, quick to deploy, and can be completed by a single person.

[0021] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
