Recently, the summary meeting of the tunnel illuminance detector product developed by Shandong Tianhe Environmental Technology Co., Ltd. was successfully held in Weifang. At the meeting, many industry professionals and customer friends arrived at the scene. After understanding, everyone highly affirmed and fully recognized the product. The tunnel illuminance detector is an intelligent monitoring device designed specifically for the lighting environment inside tunnels. By capturing real-time changes in light intensity, it provides key data support for lighting regulation, driving safety assurance, and energy-saving optimization.

At the meeting, Manager Yu of Tianhe Environmental Technology Co., Ltd. introduced, "The tunnel illumination detector is an intelligent monitoring device designed specifically for the lighting environment inside tunnels. It has the characteristics of high-precision measurement, fast response, and strong environmental adaptability. It can be widely used in highway tunnels, railway tunnels, subway tunnels and other scenarios, providing key data support for lighting control, driving safety guarantee and energy-saving optimization

Core function: Precise monitoring and intelligent regulation

Real time monitoring and data transmission

The device captures the intensity of light inside the tunnel through photoelectric sensors (such as high-precision silicon photovoltaic cells or photodiodes), converts the light signal into an electrical signal, amplifies and filters it, and achieves remote monitoring and storage analysis. For example, after the deployment of a highway tunnel, the nighttime accident rate decreased by 30% and the annual electricity savings reached 30%.

Automatically adjust lighting brightness

Based on real-time monitoring of light intensity data, the linked tunnel lighting system automatically adjusts the brightness of the lamps. Reduce power during the day to save energy, and increase brightness at night to ensure safety and avoid the "black hole effect" (excessive brightness outside the cave causing a sudden drop in visibility inside the cave) or "white hole effect" (excessive brightness inside the cave causing a decrease in visibility outside the cave).

Emergency response

In the event of a fire or other emergency, the illumination inside the tunnel may be severely affected. At this point, the detector can quickly sense changes in illumination and trigger the corresponding emergency lighting system, providing sufficient lighting support for rescue personnel.

Data Storage and Analysis

The device has a local data storage function and can store historical data of illumination changes for a long time. Through big data analysis, it is possible to predict the trend of lighting changes, optimize lighting schemes, and provide objective data support for tunnel acceptance and regular inspections.

Technical advantages: high precision, fast response, and strong environmental adaptability

high-precision measurement

Using high-precision sensors (such as imported silicon photovoltaic cells), the measurement accuracy can reach 0.1 Lux, the error is automatically corrected to less than ± 1%, and the resolution reaches 0.01 Lux. It can accurately capture subtle changes in light intensity and meet the requirements of CIE (International Commission on Illumination) for tunnel lighting measurement.

quick response

There is a good linear relationship between the instantaneous response to light changes (in milliseconds), brightness, and photocurrent, ensuring real-time data.

Strong environmental adaptability

Protection level: The equipment casing has a protection level of IP68, with dust, water, and electromagnetic interference resistance capabilities.

Temperature and humidity range: It can operate stably in a temperature range of -40 ℃ to+70 ℃ and a humidity environment of 0 to 100% RH.

Average Wu failure time: ≥ 50000 hours, ensuring long-term stable operation.

Modular design and usability

The device comes with an LCD screen that can display information such as operating status and fault alarms, making it easy to debug and maintain on site.

Supporting modular expansion, sensors or communication modules can be added according to requirements.

The product summary meeting was a complete success, and we welcome customers with such needs to come.
