Abstract:

In order to realize the rapid signals processing and control of the peripheral sensor devices of different UUV detection systems, a universal processing system for UUV target detection based on high-speed digital signal processor (DSP) is designed by using the high-speed data processing ability of DSP and the high-speed interface data interaction ability of FPGA. The system adopts the hardware architecture design of XC7Z045T chip to expand TMS320C6678 chip, and carries out programming design by configuring SPI bus to produce the clock distribution design scheme of 250MHz, 156.25 MHz, 100MHz and 50MHz. It supports 2-channel 100M Ethernet interface communication and 16 channel RS232 serial port data transmission and reception, and can expand can communication and RS485 communication according to actual needs. The experimental test shows that the system design scheme can complete the data transmission from 100M Ethernet to target detection sensor equipment, and realize the address definition, reading and writing, and data communication operations for different RS232 sensor equipment. The results show that the system design scheme achieves the purpose of rapid processing and control of Ethernet sensor devices and different RS232 peripheral sensors, and realizes the design of a universal system for UUV target detection based on DSP.
