Research of Ultrahigh Vehicle Detection System Based on Infrared Sensor

Abstract:

Ultrahigh vehicle detection system has been designed which is based on infrared sensor. In application of optical modulation & demodulation, the hardware-circuit is successfully designed by sunlight interference concern. Because of scattering properties of infrared light, software design which is applied of overlapping interference uses algorithm of pulse delay& separation. The later algorithm can well solve the measurement errors of hollow objects, which is basically opposite to the former one, but it costs scan time much more while gets lower efficiency in dynamic measurements of vehicle. The accuracy of this system is 5cm which ranges from 4m to 6m in actual test. The velocity of vehicle can reach 30km/h on the basis of the pulse delay algorithm and 18km/h with the pulse separation algorithm.
