针对DOS环境下的多通道温度采集及数据处理系统 ,存在内存管理困难、数据分析处理操作很不方便等缺点 ,而现有Windows环境下采集系统由于多线程分时造成采集时钟不准确 ,一般编程方法只能实现间隔最小5 5ms的时钟 ,且线程等级很低 ,一般误差为 10 %左右 ,难以实现精确时钟采集。为此 ,我们研制了Windows环境下的精确时钟多通道采集及数据处理系统。采用转换精度为 12位的A/D板 ,该系统可同时监测八点的温度变化。由于采用了WindowsAPI函数及多线程技术和动态连接库技术 ,可在良好的界面环境下进行数据采集和处理分析。整个系统具有极强的可移置性和扩容性 ,可满足各类强干扰条件下的温度高速采集
For DOS multi-channel temperature acquisition and data processing system, there are memory management difficulties, data analysis and processing is very inconvenient shortcomings, and the existing Windows environment acquisition system due to multi-threaded time-sharing acquisition of the clock is not accurate, the general programming The method can only achieve a minimum interval of 5 5 ms clock, and the thread level is very low, the general error is about 10%, it is difficult to achieve accurate clock acquisition. To this end, we developed a Windows environment, accurate clock multi-channel acquisition and data processing system. Using A / D boards with 12-bit conversion accuracy, the system monitors eight temperature changes simultaneously. As a result of the use of Windows API functions and multi-threaded technology and dynamic link library technology, in a good interface environment for data acquisition and processing analysis. The entire system has a very strong portability and scalability to meet the conditions of various types of strong interference under high temperature acquisition
