一、前言以计算机为中心的数据采集、处理和控制系统随着计算机技术的飞速发展和工业生产过程自动化程度的不断提高,其应用日益广泛,需要量逐年增加。在科学试验和各种工业生产过程中,大量的各种信息大都是由相应的传感器将非电量转换成电信号,这些信号由控制系统进行数据的采集和测量,并根据要求由计算机在软件的支持下进行 I. INTRODUCTION Computer-centered data acquisition, processing and control system With the rapid development of computer technology and the ever-increasing degree of automation in industrial production process, its application is more and more widely used, and its requirements increase year by year. In scientific experiments and various kinds of industrial processes, a large amount of various kinds of information are mostly converted by sensors into non-electrical signals, which are collected and measured by the control system and then sent by the computer to the software Support
