[Abstract]:The ultrasonic diagnostic instrument based on the computer platform transmits the digital signal which contains the original diagnosis after all kinds of conversion processing to the computer, and then uses the computer software to process the data to restore the ultrasonic image, and the signal needs to be high speed and real time. It is safely transmitted to the PC through the computer interface. In the common computer bus, it is not difficult to find that USB (Universal Serial bus) has the advantages of small size, good compatibility, plug and play, hot plug and play, low cost and saving system resources, among which USB3.0 can achieve a transmission rate of 5.0 Gbit / s. At the same time, USB interface has become the mainstream of PC interface. In this paper, a data transmission system based on USB3.0 is proposed, which can transmit external digital signals to computer at high speed and in real time. The main contents of this research are as follows: firstly, the hardware block diagram, the schematic diagram and PCB board, welding and debugging hardware circuit are designed according to the purpose of the research; secondly, the hardware platform of the data transmission system is realized.
