Nine characteristics of tunnel video surveillance system

Whether it's setting up a highway or exploring a subway tunnel, it's inevitable that you will encounter the need to dig a tunnel in many hours. However, the establishment of the tunnel is not an easy task, it is not only difficult but also very risky. Therefore, the establishment of the unit must also ensure that the project is in a safe environment while ensuring the quality and speed of tunneling to ensure the safety of equipment and personnel within the project. The tunnel video surveillance system is an important supporting project and base equipment in the tunnel establishment. It provides image transmission for the operation and management of all levels of departments, and monitors the important guarantee of efficient operation of the locomotive.

According to the tunnel video surveillance system developed by Jinan Huake Electric, the nine characteristics of the system are analyzed:

1, high-definition video surveillance

After the explosion-proof camera is used to complete the real-time monitoring of the working site of the tunnel, and stop the centralized display in the dispatching room and other places, it is helpful to dispatch consumption, online hidden trouble investigation, emergency rescue and other work.

2, hard disk recording and storage

The tunnel video surveillance system uses a variety of methods to stop recording on the monitor screen. Support video capture, query, playback and other functions, can randomly retrieve video files. Playback supports fast release, slow release, zoom, reduce, shift, grab frame, print and more.

3, multi-screen and single-screen display

Using a variety of combinations, it is possible to display various dynamic and static video and digital graphic information on a split screen and a combined screen, and then the monitoring center personnel command and dispatch.

4, remote control and video intercom

The tunnel video surveillance system uses centralized control functions. After being authorized, the monitoring center personnel can issue control commands to the lower-level site and underground areas. After the intercom system is broadcast, the total control center and the intercoms in each area are completed.

5. Personnel security monitoring and early warning

Huake Electric R & D Center video comparison technology, can set up alarms in the pleasant area, stop monitoring for entering personnel, and complete automatic warning for people entering the illegal section.

6, optical network communication

According to the user's practice, it can be transmitted by ordinary coaxial cable or by optical fiber or network. The optical network has high transmission rate and long interval, which can prevent electromagnetic interference, complete electrical isolation, and prevent high-voltage power and lightning induction hazard.

7, discontinuous work

The tunnel video surveillance system uses a dedicated industrial control computer system. The system operates stably and has a long service life. It can work continuously for 365 days a year.

8, real-time date and clock video overlay function

The real-time date and clock preview and video recording are stopped for the entire video image of the tunnel to ensure the integrity and authenticity of the construction process. The display mode and appearance position of the date and clock in the picture can be adjusted according to the live position stop position.

9, support networking linkage

The tunnel video surveillance system can complete the network monitoring of all levels of departments. The command terminal, the central control room and the superior guidance terminal can stop the remote command through the voice intercom to the tunnel construction. Ability to stop monitoring and control via the external Internet.
