A Infrared Ranging System For Automotive Anti-collision
In this paper, we present a high-frequency current source transmitter circuit, which uses the high-power composite pipe as the regulator and the high-speed op-amp as the feedback link. As matching the appropriate electrical parameters of the current output at high frequencies, the anti-collision system can be maintained in constant state and can be adjusted in real-time based on distance stalls in the larger context. Experimental results shows that the constant current source circuit can achieve the output gear continuously adjustable and the maximum current is up to 500mA when the input frequency is 150kHz. The constant current source circuit can be utilized in automotive infrared range system, and has an extremely important practical value.
