Description

Technical Field

[0001] This application relates to the field of tunnel construction technology, and in particular to a mobile camera and a tunnel monitoring system. Background Technology

[0002] Currently, video surveillance inside tunnels is typically achieved by fixing bullet or dome cameras to the tunnel walls. As the work face advances, the following work needs to be done to achieve real-time monitoring:

[0003] 1. Install a high density of monitoring equipment on the tunnel walls;

[0004] 2. The monitoring equipment is connected to the existing power supply line;

[0005] 3. The monitoring equipment is connected to the existing communication network;

[0006] 4. The monitoring equipment is connected to the management platform, and the monitoring personnel can switch the monitoring screen according to the progress of the work area;

[0007] 5. Maintenance and management of the front-end and back-end.

[0008] The existing technology has the following drawbacks:

[0009] 1. The daily advance of the work area may be 5-50m, requiring a high density of monitoring points and incurring high costs;

[0010] 2. When the spacing between the monitoring points is greater than 20m, it is difficult to ensure comprehensive and accurate monitoring of the work area. Even with high-density monitoring points, there are still blind spots that are difficult to cover, and a large number of monitoring points will cause management difficulties.

[0011] 3. A large number of monitoring points result in high network load, requiring more costly network security measures.

[0012] 4. The installation and debugging of the cameras need to be carried out in advance and require professional personnel to operate, resulting in a huge investment;

[0013] 5. Under the conditions of communication inside the cave, it is difficult to achieve the effect of cruising. Utility Model Content
