The passive ultrasonic radar ranging system is composed of a display host and a passive range finder, the passive range finder does not need to be powered by a storage battery and an external power source, and the passive ultrasonic radar ranging system is mainly applied to vehicle ranging and auxiliary driving. The passive range finder is mainly composed of a vibration power generation system, a photovoltaic power generation panel, an ultrasonic ranging system, a wireless transmission module and the like. The electric energy required by the working of the passive range finder is mainly obtained through three ways: collecting the vibration energy generated by the low-speed bumping of the vehicle; solar radiation energy is collected; when the vehicle runs at a high speed, vibration energy of the power generation device caused by wind is collected. Finally, the converted electric energy is stored in the farad capacitor, the power supply circuit can automatically start or stop power supply according to the voltage, the electric energy loss is reduced to the maximum extent, and the sensor is periodically triggered to transmit data to the host. The passive range finder does not need additional wiring for power supply, has no risk of spontaneous combustion of a battery, is flexible to install and can be used all day long, and the mutual relation of functional modules can be seen in a functional module structure chart.
本发明专利公开了一种无源超声波雷达测距系统,由显示主机和无源测距仪组成,其中无源测距仪不需要蓄电池和外部电源供电,主要应用于车辆测距,辅助驾驶。无源测距仪主要由振动发电系统,光伏发电板,超声波测距系统,无线传输模块等组成。无源测距仪工作所需的电能主要通过3个途径获取:收集车辆低速颠簸产生的振动能;收集太阳辐射能;车高速行驶时,收集风引起发电装置振动的能量。最终转化的电能存储到法拉电容,并根据电压大小,供电电路会自动开启或关闭供电,最大限度减小电能损耗,周期性触发传感器传输数据到主机。无源测距仪不需额外布线供电,无电池自燃风险,安装灵活,可全天候使用,功能模块的相互关系详见功能模块结构图。
