摘　　要：基于PCI总线,采用远距离长线传输和最新的设备驱动程序编程原理,研制一套用于远程多台计算机同步的定时系统,并成功应用于吉林大学汽车动态模拟国家重点实验室在驾驶模拟器仿真过程中远程多台计算机同步工作系统中.结果表明,该定时系统具有精度高、信号驱动能力强、使用方便等特点,并可以应用于其他工业控制过程中的远程计算机同步.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.
