摘要
提供了一种基于ARM处理器、Windows CE嵌入式操作系统的检测仪设计方案,介绍了软硬件设计。软件设计中,定制了操作系统,编写了硬件驱动程序,利用多线程技术实现了检测数据的实时显示,同时具有数据保存、故障分析等功能,得出了待测方波频率与测量时机的基本关系。试验结果表明,该检测仪稳定性好、精度高、操作简单,设计思想和工程实现方法对低频方波信号的物理量实时检测具有一定的借鉴意义。
Based on the ARM processor and WinCE embedded systems, this paper provided a detecting instrument design and introduced the hardware and software design. In software design, the operating system was customized, hardware drivers were pro-grammed and real-time display of detected data was achieved through multi-threading technology. The software has data saving and failure analysis functions. The relationship between pulse frequency under test and detection opportunity was obtained. The results show that the detecting instrument assumes good stability, high accuracy and convenient operation. The design ideas and engineering methods are references to real-time physical quantities detecting of low-frequency pulse signal.
