purpose of analysis, such as 3D imaging. In the figure below, the broken line stands for
control flow, while the real lines stand for data streams. The main CPU control
communicates with the built-in PC via a serial port. The built-in PC initiates USB2.0 main
control of the PC system and USB2.0 slave of the ultrasound system. The data is transferred
via USB2.0, and the main CPU system determines that the results are to be displayed
whether by the ultrasound system or by the built-in PC.
3.2.8.2
PC carry board
The industrial control PC has advantages in the aspects of reliability, signal interface methods,
power supply categories, and power consumption, so it is used as the built-in PC. The built-in
PC module consists of PC carry board, industrial control board, memory stick, HDD and fan.
The PC carry board is introduced as follows:
The data transfer between the PC carry board and the digital processing board is completed
via 2-channel USB2.0 interface;
The PC carry board communicates with the digital processing board 5474 via a serial port;
The S-VIDEO interface is used for maintaining mode display;
The USB and kilomega Ethernet interface is used for connecting the IO-BOX;
HDD supporting SATA interface is used to store 3D system data;
CPLD is used to manage the system power system;
The PC carry board obtains power of 12V, 5V or 3.3V from the mother board;
The PC carry board interfaces are shown as follows:
