The invention relates to the technical field of agricultural unmanned aerial vehicles, and provides a rotary radar time synchronization method, a rotary radar and an agricultural unmanned aerial vehicle. The rotary radar is applied to the agricultural unmanned aerial vehicle and comprises a stator and a rotor, and the rotor rotates relative to the stator. When the first infrared receiving tube rotates to a zero position identification gap of the code disc, the first infrared receiving tube receives an infrared continuous signal sent by the first infrared transmitting tube, sends a first electric pulse signal to the second infrared transmitting tube, and sends a second electric pulse signal to the rotor micro-control unit at the same time; the rotor micro-control unit receives the second electric pulse signal and records the current time as the first moment; the second infrared transmitting tube transmits an infrared pulse signal to the second infrared receiving tube; the second infrared receiving tube sends a third electric pulse signal to the stator micro-control unit; and the stator micro-control unit receives the third electric pulse signal and records the current time as a second moment. The time synchronization method is low in time delay and high in precision, and the time synchronization efficiency can be improved.

    本申请涉及农用无人机技术领域,提供一种旋转雷达时间同步的方法、旋转雷达和农用无人机。旋转雷达用于农用无人机上,包括定子和转子,转子相对于定子转动。当第一红外接收管转至码盘的零位识别缺口时:第一红外接收管接收到第一红外发射管发送的红外连续信号,向第二红外发射管发送第一电脉冲信号,同时向转子微控制单元发送第二电脉冲信号;转子微控制单元接收到第二电脉冲信号,记录当前时间为第一时刻;第二红外发射管向第二红外接收管发送红外脉冲信号;第二红外接收管向定子微控制单元发送第三电脉冲信号;定子微控制单元接收到第三电脉冲信号,记录当前时间为第二时刻。本申请的时间同步方法时延低,精度高,能够提高时间同步效率。
