The invention discloses a simplified multi-mode vehicle detector which comprises a microprocessor, a geomagnetic sensor chip, an operational amplifier, a radar ranging module, a power supply unit, a microwave radio frequency communicator, a matched transceiving antenna of the microwave radio frequency communicator and a visible light auxiliary detection circuit. An output signal of the geomagneticsensor chip is amplified by the operational amplifier and then is input to a geomagnetic signal input end of the microprocessor; the microprocessor is connected with the radar ranging module througha ranging interface end, is connected with the microwave radio frequency communicator through a communication end, is connected with the power supply unit through a control output end to ensure power-saving work of related parts, and is connected with the visible light auxiliary detection circuit through a light detection interface end. According to the invention, a unique grading progressive strategy is adopted to detect vehicles; in most cases, calculation is carried out by geomagnetic and/or visible light data acquired by ultra-low power consumption; the detection result with high confidence can be output without additionally starting a radar ranging module with high power consumption, the detection accuracy is considered, the product battery replacement and scrapping speed is greatly reduced, the product is flexible, economical and practical, a large amount of manpower and material resource operation and maintenance investment can be saved, and the method is suitable for various intelligent traffic applications.

    本发明公开了一种精简型多模车辆检测器,包括微处理器、地磁传感器芯片、运算放大器、雷达测距模块、供电单元、微波射频通讯器及其配套收发天线、可见光辅助检测电路。地磁传感器芯片的输出信号经运算放大器放大后输入到微处理器的地磁信号输入端,微处理器通过测距接口端与雷达测距模块连接、通过通讯端与微波射频通讯器连接、通过控制输出端与供电单元连接以确保相关部件省电工作、通过光检测接口端与可见光辅助检测电路连接;本发明采取独特的分级递进策略检测车辆,大部分情况下单凭超低功耗采集得到的地磁和/或可见光数据进行计算,即可输出置信度高的检测结果而无须另行开启功耗较大的雷达测距模块,既兼顾了检测准确率,也大大延缓了产品电池更换及报废的速度,产品机动灵活、经济实用,能节省大量的人力物力运维投入,适用于各种智能交通应用。
