    • The vehicle detection apparatus includes a communication unit, a magnetic sensing unit, a calibration information generation unit, a vehicle detection unit, and a control unit. The communication unit receives information about movement of a reference vehicle from a central management center. The magnetic sensing unit senses the change in a magnetic field attributable to the movement of a vehicle, and generates a magnetic signal. The calibration information generation unit generates calibration information. The vehicle detection unit calibrates the change in the magnetic signal attributable to movement of an actual vehicle based on the calibration information, and detects the movement of the actual vehicle. The control unit controls the above units, and sets the mode to calibration information generation mode in order to generate the calibration information and to vehicle detection mode in order to sense the movement of the actual vehicle.
    • 车辆检测装置包括通信单元,磁感测单元,校准信息生成单元,车辆检测单元和控制单元。 通信单元从中央管理中心接收关于参考车辆的移动的信息。 磁感测单元感测归因于车辆的移动的磁场的变化,并产生磁信号。 校准信息生成单元生成校准信息。 车辆检测单元基于校准信息来校准归因于实际车辆的移动的磁信号的变化,并且检测实际车辆的移动。 控制单元控制上述单元,并且将模式设置为校准信息生成模式,以便产生校准信息和车辆检测模式,以感测实际车辆的移动。
