摘要
提出一种适用于分布式数据检控系统的数据采集通道扩展方法及其性能评价原则．它能几十倍甚至几百倍地增加数据采集点，在扫描频率允许的情况下，能增强抖动抗干扰能力，又能大幅度地提高整个数据检控系统的信价比．该系统尤其适用于热工和其他“慢变化过程”动态参数的检测．
A method for expanding the channels of data acquisition unit used in the distribut ed. Microcomputer data measure & control system is introduced. And the appraisal of the method is also introduced. The method may increase the count of the data acquisition dot from tens to hundreds times and the ability to resist the shake disturbance, and may also raise the price performance ratio of all the distributed data measure & control system greatly.It can be used to measure the dynamic parameters in thermal engineering and other 'slow-responce process' as well.
