The invention discloses a low-power-consumption dual-mode parking space detection circuit based on radar and geomagnetism, in particular to a low-power-consumption dual-mode parking space automobile state detection circuit based on a narrow-bandwidth radar sensor and a three-component geomagnetic sensor, which is characterized in that a three-component geomagnetic sensor and a narrow-bandwidth radar sensor are used for acquiring data; when an environment amount changes, a low-power-consumption control circuit is excited to enter a normal working mode, collected data enter an MCU main control unit to be processed and then are connected with an NBIOT module, and the data processed by the MCU unit are sent to a cloud end through an NBIOT narrow-bandwidth Internet of Things circuit in cooperation with an SIM wireless transmission circuit; when the change does not occur, the low-power-consumption control circuit is excited to enter a low-power-consumption working mode, three-component geomagnetic acquisition data directly enter the MCU module and are monitored in real time by the MCU, and the NBIOT narrow-bandwidth Internet of Things circuit and the SIM wireless transmission circuit are in a low-power-consumption dormant state, so that the service life of the battery is prolonged; and when the MCU monitors that the environmental quantity is changed again, the low-power-consumption control circuit is excited to enter a normal working mode.

    本发明公开了一种基于雷达和地磁的低功耗双模车位检测电路,基于窄带宽雷达传感器和三分量地磁传感器的低功耗双模车位汽车状态检测电路,由三分量地磁传感器以及窄带宽雷达传感器采集数据,当环境量发生改变时,激励低功耗控制电路进入正常工作模式,采集过后的数据进入MCU主控单元进行处理后连接NBIOT模块,将MCU单元处理后的数据由NBIOT窄带宽物联网电路协同SIM无线传输电路发送至云端;未发生改变时,激励低功耗控制电路进入低功耗工作模式,三分量地磁采集数据直接进入MCU模块,由MCU实时监测,NBIOT窄带宽物联网电路及SIM无线传输电路将处于低功耗休眠状态,延长电池的使用寿命;当MCU监测到环境量再次发生改变时,激励低功耗控制电路进入正常工作模式。
