摘要
本文主要介绍了微机过程通道板的性能指标和用途,并以 IBM-PC 微机过程通道板组成的采集系统为例作了详细阐述。微机广泛地应用于测控系统中,微机过程通道板在测控系统中是联接微机和测控对象的桥梁。我们研制了各种类型的过程通道板,其中 IBM-PC 微机过程通道板在风洞测控系统、工厂、大学实验室等地方得到了较好应用。由微机过程通道板组成的测控系统方便灵活,测量精度高、成本低、性能稳定可靠。
The performance index and applications of microcomputerprocess channels are introduced in this paper and the data aquisitionsystem that is composed of the IBM-PC microcomputer process channelboard is described as example in detail.Microcomputers are used widelyin measurement and control system.The microcomputer process channclboard is bridge that links up microcomputer and measuring and Cotrol-ling objects of the measurement and control system.We have developedall kinds of process channel board.Among them the IBM-PC microcompu-ter process channel is used well for measurement and control system ofwind tunnels,factories,university laboratories etc.The measurementand control system which is comprised of microcomputer and processchannel provides the feature-of convenient flexibility,high measure-ment accuracy,low cost and steady reliability performance.
