1. Industry background
With the acceleration of China's modernization process, in order to promote rapid economic development, the country has vigorously developed infrastructure . Hilly terrain is often encountered in highway construction, subway construction, high-speed rail construction, and mining area construction . In order to shorten driving mileage , tunnel construction has become preferred option . Due to the complex environment inside the tunnel, the closed space, and the long and narrow driving environment, it is not conducive to the wiring of the monitoring system. Moreover, once a traffic accident or fire occurs when passing through the tunnel or during tunnel construction , it is easy to cause secondary accidents. If advanced monitoring and management measures are not adopted, it is easy to cause serious safety accidents and bring economic losses to the country.
To this end, we launched the SkeyeVSS tunnel video surveillance system. Using this system, we can effectively improve the safety factor of tunnel construction projects, and conduct real-time monitoring of people and vehicles entering and exiting the tunnel , as well as the internal environment of the tunnel, thereby ensuring construction safety.
2. System architecture
The SkeyeVSS tunnel video surveillance and early warning system provides real-time and intuitive video information for special operation safety production, achieves full-process and all-round safety production management, provides direct evidence for accident investigation and analysis, and effectively improves special operation safety supervision and emergencies. Early warning identification, emergency command and handling capabilities enable standardized and intelligent supervision of tunnel construction operations.
3. Main functions of the system
1. 24-hour visual monitoring
It can realize 24-hour real-time monitoring of each video point at the tunnel construction site, support two-way real-time transmission of video, pictures, voice, and data, realize real-time visual interaction between back-end monitoring personnel and front-end construction personnel, and can wear and operate the equipment of construction personnel. Behavior is monitored on a daily basis.
2. Real-time analysis and early warning
When the front-end device detects the occurrence of a predetermined special event, it sends alarm information to the platform. The platform can receive information such as external alarms, video signal loss, offline, lens obstruction, and motion detection alarms uploaded by the device. The platform captures the alarm status and information recorded by all devices, and displays the alarm level, alarm mode, alarm type, and alarm time of the device in a unified manner. Video interception can be performed based on the device alarm information to obtain video screenshots at the alarm moment.
3. Monitor abnormality and alarm prompts
Safety situations are identified through image recognition technology. The identification types include people, behaviors, safety helmets, work clothes, open flames, smoke, etc. Wearing behaviors that do not meet the requirements and other dangerous behaviors can be monitored and warned in real time. When the system detects that a person entering the construction site is not wearing a safety helmet/reflective clothing, it will snap a picture and save it in time, and link the voice broadcast to issue an alarm prompt. At the same time, the alarm information will be transmitted to the platform. The background monitoring personnel will immediately receive the violation prompt. Promptly correct violations on site to reduce the possibility of greater dangerous losses.
4. Alarm record storage and quick query
The system can identify tunnel construction workers who are not wearing safety helmets or reflective clothing, and store alarm screenshots and videos, including time, location, alarm screenshots, alarm videos, etc., to facilitate personnel safety management; workers can identify the tunnel construction personnel according to the equipment name, channel, etc. ID, alarm level, etc. can be used to query the behavior of not wearing a safety helmet.
5. Voice call intercom
The monitoring center, guardians and operators can have voice intercoms at any time to understand the on-site operation situation.
6. GIS/Beidou positioning function
Accurately locating the specific location of the operation provides positioning assistance for workers to rescue them in the event of an accident.
4. Summary of the plan
The SkeyeVSS tunnel video surveillance and early warning system is used to realize high-speed, real-time transmission of video images, voice and other data information. It can intuitively understand and grasp the real-time situation of each video point of the construction, so as to monitor the construction site promptly and accurately anytime and anywhere. At the same time, installation is quick, maintenance is simple, and the effect is stable.
In addition, the SkeyeVSS tunnel video surveillance and early warning system also has rich video capabilities, including video surveillance live broadcast, recording, cloud storage, retrieval and playback, aggregation and distribution, and cascade sharing; at the same time, it supports compatibility with different brands, different models, and different types. The video stream (rtsp/rtmp/http/onvif), equipment (IPC/NVR/4(5)G law enforcement recorder), and monitoring platform (GB28181/EHome) are connected to the SkeyeVSS video fusion system, which can quickly connect and develop third-party platforms , making it easy to build a one-stop video aggregation solution.
