The design principle is given for the interface circuit of serial communication system of power supply for 25T passenger car.

Design and realization of high-speed serial communication simulator based on PCI bus;

Design on the serial communication of the measuring and controlling systems for the hydraulic pressure and rotate speed in the friction welding machine;

Implementation of serial communication between personal computer and C8051F000 in sampling of heart sound;

Parameter setting of DSP-based servo system via serial communication;

The thermal parameters monitoring system of industrial mini-steam turbine was developed, which was based on serial port communication.

0 to design the serial port communication program.

Then it discusses in detail the steps of realization and part of functions of developing the serial port communication program under eMbedded Visual C++4.

The program design of series communication between PLC and computer;

The system uses communication interface such as RS-232 to accomplish series communication between PC and data acquisition machine,which realizes real-time acquisition and supervision of the motion parameters of vehicle and data analysis under support of the database system in order to achieve the evaluation of auto-braking performance.

Power Builder is one excellent toolkit of establishing application system of database, but it did not provide the command, function and control of series communication.
