摘要
简要介绍了以 PC104 为核心的网络化数据采集系统的工作原理及其软件工作流程,详细分析了系统中担当网络数据传输任务的 PC104 模块及其软件设计的重要地位。根据系统的工作模式,阐述了 PC104 软件的设计目标并提出了其多线程解决方案。实践证明,Windows9x 操作系统的多线程机制及其线程间的同步技术能有效保证网络化数据采集系统安全可靠地运行。
The work principle of networked data acquisition system based on PC104 and its software work diagram are introduced. PC104 module,which acts as data transfer in the system,and the importance of its software design are analyzed. Then the design object of PC104 software and its multi-thread resolution are presented based on the system working mode. It proves that the multi-thread mechanism of Windows9x OS and the technology of synchronization in multi-thread can ensure effectively that the networked data acquisition system can run safely and reliably.
