Embodiment Construction
[0048] Such as figure 1 As shown, the present invention includes a communication module 1 , a main control module 2 , a DSP (Digital Signal Processing, digital signal processing) module 3 , a transmitting module 4 , a receiving module 5 and a power supply module 6 . Triggered by the synchronous command of the upper computer 7, the main control module 2 triggers the DSP module 3 to generate the required signal sequence, and the energy is sent to the water by the transducer 8 through the transmitting module 4. Transducer 8 receives signals transmitted by other nodes, and sends them to DSP module 3 after being preprocessed by receiving module 5 . The DSP module 3 extracts the target signal and calculates the delay value, and sends it to the main control module 2 . The main control module 2 packs the 4 delay measurement data into a communication protocol and sends them by the communication module 1 .
[0049] The asynchronous serial interface (SCI) is used between the communicat...
