采用霍尔传感器的旋翼频率采集设计

摘要

为达到对旋翼飞机的控制,需要对旋翼转速进行采集.霍尔转速传感器以其高可靠性等优点常被用来测量转速.介绍了一种使用霍尔传感器进行旋翼转速采集系统,包括硬件构架,逻辑采集单元和软件设计,并给出了优化策略;通过试验数据分析,采集精度达到了预期.%In order to control the flight of rotorcraft,high reliability hall sensor is usually used tocalculate the speed of rotor wings.This paper introduceda rotor speed calculation system based on hall sensor,includinghardware platform,frequency counter entity and the software design.Also the possible optimized methods are provided.The experiment data resultindicates that the system obtain the expected precision.
