The invention relates to the technical field of vehicle detectors, and discloses a parking space vehicle detector, which comprises two ultrasonic probes which are independent units and are used for self-transmitting and self-receiving and synchronous and staggered transmission; a microwave probe; and the microwave sensor is used for carrying out self-inspection on the microwave probe. According to the parking space vehicle detector provided by the invention, microwave and ultrasonic sensors are adopted for detection, and the detection is not influenced by the external environment; multi-probe acquisition can effectively reduce the probability of missed detection; the ultrasonic inclined 45-degree design can prevent water from being accumulated in the center of the probe; a probe self-checking function is added, so that whether the probe is damaged can be identified; the ultrasonic receiving circuit adopts an active filter design, so that external interference signals can be effectively reduced.

    本发明涉及车辆探测器技术领域,且公开了一种车位车辆探测器,包括:超声波探头,数量为两个,均为独立单元,用于自发自收,并且同步错时发送;微波探头;微波传感器,用于对微波探头进行自检。本发明提出一种车位车辆探测器,本发明采用微波和超声波传感器进行探测,不受外部环境影响;多探头采集,可以有效降低漏检概率;超声波斜45度设计可以防止探头中心积水;增加探头自检的功能,可以识别探头是否损坏;超声波接收电路采用有源滤波器设计,可以有效降低外部干扰信号。
