Blue ResidenceTunnel VOCs online monitoring equipmentUsed to achieve real-time monitoring of particulate matter and toxic and harmful gases in tunnels, and to achieve docking control between monitoring systems and other systems in tunnels.

A gas detection instrument for real-time online monitoring of volatile organic compounds in tunnel environments; It is a standardized, modular, and specialized system integration product that integrates gas sampling, gas filtration, real-time concentration display, local sound and light alarm, equipment linkage, data remote, and other functions; The product adopts a three proof design and can be directly used outdoors.

Mainly achieve the following aspects:

(1) By installing temperature and humidity sensors, harmful gas sensors, particulate matter monitors, etc. inside the tunnel, the environment is monitored, mainly including real-time monitoring of VOCs, harmful gases (carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen dioxide, methane, hydrogen sulfide, etc.), smoke, wind speed, oxygen content, etc;

(2) Analyze the data monitored by the front-end, and automatically provide alarm prompts when abnormalities are found; When harmful gases are found to exceed the standard in the tunnel, the ventilation system will automatically start and control for timely ventilation;

(3) By establishing a monitoring center, timely monitoring of the environmental conditions inside various highway tunnels and the operational status of various control facilities can be achieved; Centralize the management of road alarm information, achieve statistical analysis of alarms, and realize linkage control between environmental abnormalities and other controlled facilities.
