Abstract: A kind of software and hardware design was studied for a complete set of timing system based on PCI bus. To realize the design, two theories were adopted, which were remote longline transmission theory and a newest device driver program theory. This timing system owns lots of merits, such as high precision, strong ability of signal drive, convenience for use and so on. It not only was realized synchronization for more than one remote computer in the simulation process of driving simulators in State Key Laboratory of Automobile Dynamic Simulation, but also was applicable to getting synchronization for remote computers in other industry control process.

Key words: synchronize, RS485 serial communication, windows driver model, dynamic link library
