covi detector principle

The visibility in the tunnel is mainly affected by three factors: the illumination of the lighting source in the tunnel, dust in the air, vehicle exhaust and other pollutants. If the visibility in the tunnel is reduced, it will create a huge safety hazard for vehicles and pedestrians. First of all, if the traffic volume in the tunnel is large, once the visibility is reduced to a certain extent, it is easy to form a highway blockage, increasing the risk of collision between vehicles and pedestrians. Secondly, the tunnel with low visibility is also easy to cause traffic violations such as running red lights and changing lanes, thereby increasing the accident rate of vehicles and pedestrians.

Therefore, monitoring the visibility inside the tunnel becomes very important. Monitoring the visibility and environmental conditions in the tunnel can effectively reduce the tunnel accident rate and promote the safety and smooth flow of vehicles and pedestrians in the tunnel, which is an important means to improve the safety and reliability of the transportation system.

covi detector principle - covi detector, that is, the tunnel visibility detector, the main reason for monitoring visibility in the tunnel is to ensure the safe travel of vehicles and pedestrians in the tunnel. It mainly measures the visibility parameters in real time through the sensors installed in the tunnel, so as to judge the visibility situation in the tunnel. The following are the main components of the tunnel visibility detector:

Sensors: usually include photoelectric sensors, infrared sensors, smoke sensors and other sensors. These sensors can detect the light source, smoke, temperature, humidity and other parameters in the tunnel in real time, and transmit the detected data to the control platform.

Control platform: The control platform is the core component of the tunnel visibility detector, which can receive the data transmitted by the sensor in real time, calculate, process and store the data, and finally generate a visual report for maintenance personnel to monitor and manage in real time.

Communication equipment: Tunnel visibility detectors usually apply wired or wireless network connections to achieve remote monitoring and data transmission between the tunnel and the monitoring center.

The function of tunnel visibility detector mainly has the following points:

Improve tunnel safety: The tunnel visibility detector can monitor the visibility in the tunnel in real time, avoid accidents caused by reduced visibility, and improve the safety of vehicles and pedestrians.

Fast detection of abnormal conditions such as smoke in the tunnel: The tunnel visibility detector can quickly detect the visibility in the tunnel through sensors and other devices. Once an abnormal situation is found, the alarm is immediately reported to help maintenance personnel quickly deal with it.

Provide data support for maintenance personnel: Through the data report provided by the tunnel visibility detector, maintenance personnel can understand the environmental conditions in the tunnel and take appropriate measures to maintain the facilities in the tunnel when necessary.

In short, the tunnel visibility detector is a critical equipment for tunnel traffic safety, which can improve the safety and reliability of the tunnel, but also provide data support for the maintenance and maintenance of tunnel facilities.
