Design and research on condition monitoring system of brake light of cars

In order to realize the real time detection of the brake lights, this paper developed a new condition monitoring system, and designed the monitoring circuit, which could precisely detect the working condition of the brake lights via measuring the output voltage variation of the photoelectric isolator emitter and photo-resistance. Also, this paper developed the modularization software system, which improved the operation efficiency. Lots of experiments showed that the results were accurate and reliable, and the design of the monitoring system was reasonable.
