The invention discloses an active electromagnetic type parking space vehicle detection method, belongs to the technical field of parking space vehicle detection, and aims to solve the problem that the existing parking space is inaccurate in vehicle state detection. The method comprises the following steps that (1) a parking space lock, an electromagnetic detection coil and a vehicle detection controller are installed in the center of a parking space; (2) during vehicle detection, the electromagnetic detection coil actively emits a low-frequency electromagnetic field, when a vehicle exists in the parking space, the low-frequency electromagnetic field can form an eddy current on a chassis metal layer of the vehicle, the eddy current can generate an additional electromagnetic field, the electromagnetic detection coil receives the additionally generated electromagnetic field and outputs an eddy current signal, and the eddy current signal is transmitted to the parking space; the vehicle detection controller detects the size of the eddy current signal so as to judge whether a vehicle exists or not; (3) the vehicle detection controller usually adopts a time-sharing detection mode; and when the eddy current signal is detected to change, entering a rapid detection mode. The invention is suitable for an active electromagnetic parking space vehicle detection method.

    本发明公开了一种主动电磁式停车位车辆检测方法,属于停车位车辆检测技术领域,目的在于解决现有停车位对车辆状态检测不准确的问题。其包括以下步骤:(1)在停车位中央安装车位锁、电磁检测线圈、车辆检测控制器;(2)车辆检测时,电磁检测线圈主动发射低频电磁场,当停车位有车辆存在时,低频电磁场会在车辆的底盘金属层形成涡流电流,涡流电流会产生一个额外的电磁场,电磁检测线圈接收到额外产生的电磁场,并输出涡流信号,车辆检测控制器检测涡流信号的大小,即可判断车辆是否存在;(3)车辆检测控制器平常采用分时检测模式;当检测到涡流信号发生变化时,进入快速检测模式。本发明适用于一种主动电磁式停车位车辆检测方法。
