摘　　要：应用多线程同步机制充分利用Windows系统的丰富资源,是Windows系统的重要特点。详细分析了Windows NT操作系统的多线程同步机制和同步对象,并以其在检测仪和光电测量设备同步通信程序开发中的应用为实例,就如何实现应用程序和设备驱动程序共享事件对象、实现二者同步通信问题进行了详细论述。给出了该应用的实现原理和具体的设计步骤,同时还介绍了Windows NT下硬设备驱动程序的编写。应用表明,此方法提高了效率和实用性,节省了系统资源。Application of multi- thread synchronous mechanism to make full use of system resource is one of the important features of Windows. Multi-thread mechanism and synchronous object in Windows NT is analyzed, and communication between application and device driver with sharing event object through using synchronic event in developing communication program of detecting instrument and photoelectric measure device are presented in detail. The principle and specific designing steps are given and how to develop the hardware device driver in Windows NT i- introduced.
