Embodiment 1
[0055] Such as Figure 1-8 As shown, a UAV sound recognition positioning device, including a wireless sound sensor network and a general controller;
[0056] The wireless sound sensor network includes a plurality of wireless sound sensor nodes, and each wireless sound sensor node is mainly composed of seven sound sensors, a signal filter amplification module, an ADC module, an MCU and a wireless transmission module; the seven sound sensors use Record the ambient sound at the location and transmit the ambient sound signal to the signal filtering and amplifying module; the signal filtering and amplifying module is used to filter and amplify the ambient sound signal and transmit it to the ADC module; the ADC module is used to filter and amplify the The ambient sound signal is sampled and transmitted to the MCU; the MCU is used to perform audio coding on the ambient sound signal adopted by the ADC module and send it to the next wireless sound sensor node or general controller thro...
Embodiment 2
[0086] This embodiment provides a method for identifying and locating a drone using the device described in Embodiment 1, comprising the following steps:
[0087] S1. Distribute the wireless sound sensor nodes in the area where UAV identification and positioning are required, and the distance between each wireless sound sensor node is between 300-500m;
[0088] S2. The seven sound sensors in the wireless sound sensor node start to record the ambient sound, and transmit the ambient sound signal to the signal filtering and amplifying module; the signal filtering and amplifying module filters and amplifies the environmental sound signal and transmits it to the ADC module; The ADC module samples the filtered and amplified ambient sound signal and transmits it to the MCU; the MCU performs audio encoding on the ambient sound signal adopted by the ADC module and sends it to the next wireless sound sensor node nearest to itself through the wireless sending module or General controller...
