| description | A large-scale and long-distance distributed explosion sound wave test system based on BeiDou satellite navigation system and LoRa wireless communication technology is proposed for the characteristics test of the acoustic signal in the far field of the explosion field. The system uses FPGA as the core controller and acquisition and storage of explosion sound wave signals is realized by using stored testing technology.Time synchronization as well as node positioning information in long-distance distributed measurement is achieved by the timing and positioning function of BeiDou satellite navigation system. On the other hand, linear spread spectrum modulation technology of LoRa is used to form a large-scaler distributed sensor network with long-distance and low power consumption. The experimental result indicates that the proposed distributed test system acquired valid data at the same time realizes time synchronization of 100 ns, positioning accuracy of 2 m and large-scale network coverage of 2 km. |
