摘 要: 讨论在制冷循环系统中,利用Visual Basic设计开发HP34970A数据采集器二次处理软件的过程。内容包括软件的人机界面设计、采集数据的获得、数据库的调用、采集结果的显示以及软件开发过程中需要注意的问题等,并结合部分程序源代码进行分析。尽管设计基于的系统是以蒸发器、冷凝器、节流阀、压缩机四大部件为组成部分的蒸气压缩式制冷系统,但对其他形式的制冷系统,程序开发方法和技术同样具有重要的参考价值。 The process of utilizing Visual Basic to design and develop secondary treatment software for HP34970A data sampling instrument for refrigeration system is presented mainly. It concludes design of human-machine interface of the software, realizing of data acquisition, transferring of data-base, displaying of data sampling and problems needed more attention. Some source code of computer language is analyzed. Though the standard refrigeration system based on evaporator, condenser, throttle valve, compressor, its means and technique are references for the other refrigeration systems.
