Method for road guardrail collision detection
The invention discloses a method for road guardrail collision detection. A controller comprises an inner core, an ADC module and a peripheral interface; the output port of an external pressure sensoris connected to the input end of the ADC module; the output port of an external pressure sensor is connected to the peripheral interface of the controller. According to the method for road guardrail collision detection of the invention, the pressure sensor and the acceleration sensor are combined to detect the collision condition of a road guardrail, and the pressure sensor can effectively avoid false alarms caused by unreal collision conditions due to road surface vibration. A system is simpler to realize, so that the complexity of the system is simplified, and the cost is effectively reduced; under a non-collision condition, the controller only uses the ADC module to acquire the output of the pressure sensor, and the inner core is in a sleep mode, so that the power consumption of the system is reduced, and the controller is suitable for application occasions of battery power supply.
本发明公开了一种用于道路护栏碰撞检测的方法，所述控制器包括内核、ADC模块和外设接口，所述外部压力传感器的输出端口连接于ADC模块的输入端，所述外部加速度传感器输出接口与控制器的外设接口相连接，本发明通过使用压力传感器和加速度传感器相结合来检测道路护栏的碰撞情况，压力传感器可有效避免如路面震动造成的非真实碰撞情况造成的误报。而且使得系统实现更加简单，这样既简化了系统复杂度，又有效降低了成本；在非碰撞情况下控制器仅由ADC模块采集压力传感器的输出，内核处于休眠模式，降低了系统功耗，从而适应于电池供电的应用场合。
