The invention provides a geomagnetic vehicle detector test simulation device, a test system and a method, the simulation device is used for generating or adjusting the interference output intensity of a self-built magnetic field to simulate the magnetic field change condition of a parking space when a vehicle enters and exits a garage, and the method comprises the following steps: sampling the magnetic field change quantity of a sampling point position for multiple times according to a preset frequency when the vehicle enters and exits the garage; forming control template parameters according to statistical convergence results of the multiple pieces of sampling data; controlling a magnetic field simulation device to start to generate a self-built magnetic field at the detected point according to the control template parameters, and acquiring control data corresponding to different parking space states when the simulated vehicle enters and exits from the garage; performing a comparison test on parking space state data output by the tested geomagnetic vehicle detector in the self-built magnetic field and control data corresponding to different parking space states when the simulated vehicle enters and exits from the garage; through data comparison and analysis, the working performance of the geomagnetic vehicle detector can be evaluated, and the test passing rate of the geomagnetic vehicle detector can be calculated without testing in an actual parking lot, so that a large amount of time and resources are saved.

    本发明提供了一种地磁车检器测试模拟装置、测试系统和方法,模拟装置用于产生或调节自建磁场的干扰输出强度,以模拟车辆出入库时车位的磁场变化情况,所述方法按照预设频率多次采样车辆出入库时,采样点位置的磁场变化量,将多个采样数据的统计收敛结果形成控制模板参数;在被测点位按照控制模板参数控制磁场模拟装置开始产生自建磁场,并获取模拟车辆出入库时不同车位状态对应的控制数据;将被测地磁车检器在自建磁场中输出的车位状态数据,与模拟车辆出入库时不同车位状态对应的控制数据作对比测试;通过数据对比分析,可以评估地磁车检器的工作性能,并计算出地磁车检器的测试通过率,无需在实际的停车场进行测试,节约大量时间和资源。
