[0022] The connecting bracket 303, a crucial component of the entire sensor structure, plays a crucial role in supporting and securing the sensor. It securely connects the ultrasonic sensor 302 and ultrasonic receiver 304 at a specific position and angle, ensuring the relative positioning accuracy between them and a stable transmission and reception path for the ultrasonic waves. In complex drone flight environments, even with pan / tilt rotation or fluctuating flight postures, the connecting bracket's robust structure maintains the relative positions of the components, ensuring stable sensor operation. The ultrasonic sensor 302 is the signal source for wind speed detection. During operation, it transmits ultrasonic pulse signals into the surrounding air at a set frequency and time interval. These ultrasonic signals propagate through the air at a specific speed, and their propagation characteristics change when encountering air flowing at different speeds. In complex airflow environments, such as the variable updrafts and downdrafts in mountainous areas or the turbulent airflow in urban canyons, the ultrasonic sensor 302 continuously and stably transmits signals, providing the initial signal source for subsequent wind speed detection. In tandem with the ultrasonic sensor 302, the ultrasonic receiver 304 is always ready to receive the airborne ultrasonic signals. Because air movement affects the propagation speed and path of ultrasonic waves, the received ultrasonic signal will vary in time and phase compared to when it was transmitted. The sensor body 301 aggregates the raw signal data emitted by the ultrasonic sensor 302 and the airborne signal data received by the ultrasonic receiver 304. The built-in computing chip, based on the detection data, applies a complex algorithm, taking into account factors such as the time difference and phase difference of ultrasonic waves propagating through the air, to accurately calculate the wind speed components in different directions in the current environment. Ultimately, this achieves high-precision three-dimensional wind speed detection, providing reliable wind speed information for the safe flight and mission execution of drones in complex environments.
