Abstract

Design of one calibration system for vehicle speed monitoring device based on ground loop sensors using the direct digital frequency synthesis technology. The calibration system can generate one kind of sinusoidal signals attached onto the excitation loop sensors, which frequency, time interval is adjustable. The sinusoidal signal simulates the fast vehicle and couples with the signal from the ground loop sensor at maximum degree to excite the vehicle speed monitoring device, which performances can be verified by the calibration system.
