Abstract: The auto distance headlight automatic monitoring electrical system can be divided into long-and-short distance light force monitoring part, auto environment light force automatic monitoring part, clock monitoring automatic power-on part, liquid crystal displaying long and short distance light on-and-off part, active automatic pressing controlling part. The whole system is focused on analogous circuit and accompanied with digital circuit monitoring. The system controls the whole condition through 51MCU and detects the visible light force brightness by photoresistor reliably. Based on demonstrations, the system can perform auto light force adjustment and long and short distance light transferring.
