Abstract

The invention discloses a tunnel illumination detection system and method, and the system comprises a program control light source which is used for simulating the brightness change outside a tunnel, can achieve the preset brightness output, and collects, stores and outputs the brightness data, and a brightness instrument which comprises a brightness measurement unit and a signal processing circuit. The signal processing circuit can convert a brightness analog signal of the brightness measuring unit into a digital signal; and the detection equipment is connected with the brightness instrument, is in wireless communication with the program control light source system, can set the sampling period and time of the brightness instrument, and can display and store the brightness value acquired by the brightness instrument. The system has the characteristics of high measurement speed, low labor intensity, convenience in data recording and processing and good safety.

Description

technical field [0001] The invention relates to the technical field of tunnel lighting detection, in particular to a tunnel lighting detection system and method. Background technique [0002] The responsiveness of the tunnel dimming system is worthy of attention. The response of the tunnel brightness adjustment system is too sensitive, and the lights in the tunnel will flicker, which will affect driving and cause traffic safety hazards. At the same time, frequent changes in brightness will also reduce the life of the lamps; if the response of the tunnel brightness adjustment system is too slow , The lighting adjustment in the tunnel is not timely, which may cause unnecessary waste of energy, or even fail to reach the necessary brightness and cause traffic accidents. Therefore, it is necessary to detect the tunnel brightness adjustment system in the tunnel to avoid the influence of the lighting system on driving. [0003] The original industry standard is to use the point-b...
