Working principle of the tunnel luminosity monitor

The working principle of the Tunnel Light Brightness Monitor is to sense the light intensity in the tunnel through the photosensitive element, and through the steps of signal conversion, digital processing, data processing and analysis, it can achieve the real-time monitoring and prediction of the tunnel light brightness. At the same time, it can also transmit data to the terminal equipment for real-time analysis and processing by relevant units.

It can monitor the light intensity in the tunnel in real time and automatically adjust the switching status of the lighting equipment according to the preset parameters to ensure that the light intensity in the tunnel is always maintained in the best state. The monitor not only meets the CIE requirements on tunnel lighting measurement, but also complies with the "Design Code for Road Tunnel Ventilation and Lighting", ensuring stable operation in all kinds of harsh field environments.

Advantages

High linearity: The device adopts advanced photoelectric sensors, which can monitor the luminance and photocurrent in real time and linearly, ensuring the accuracy and reliability of the measurement data.

Self-contained display: the device comes with a LCD display, which is convenient for users to view the operating status, fault alarms and data storage information at any time, without the need to connect additional display devices.

Multiple ranges available: according to different application scenarios and light intensity range, users can choose the appropriate range to ensure the measurement precision and accuracy.

High-precision calibration: The device is calibrated at 25℃ room temperature to ensure that the measurement error is less than ±1%. This greatly improves the accuracy and reliability of the measurement.

Instantaneous response: The measurement characteristics of the device are linear and have an instantaneous response to light changes. This means that no matter how the light intensity changes, the device can quickly and accurately respond and adjust the output.

Multiple output modes: In order to facilitate data transmission and integration, Tunnel Brightness Monitor supports multiple output modes, such as analogue signals, digital signals, etc., to meet the needs of different users.

Tunnel brightness monitor is widely used in city tunnels, highway tunnels, railway tunnels and other occasions, which can achieve real-time monitoring and control of light intensity in tunnels.
