Abstract
An current mode calibration apparatus for ground induction coils velocimeter was developed. Compared with the traditional calibration apparatus, the paper chose current signal as the interference signal in stead of the switch signal for the simulation of the inductance change when the vehicle pass the ground induction coil; adopted ARM9 singlechip and Linux operating system as the platform for the software and hardware development, and analyzed the choice of interference coils. The field test results indicate that the calibration apparatus is applicable to the ground induction coils by different manufacturer, and has the advantages of convenience for carrying, high rate of accuracy, and so on.
