近年来,随着科学技术蓬勃发展,微机应用日益广泛,以微处理器和A/D 转换器等部件组成的通用化数据采集装置已成为科学研究、生产过程控制和智能仪器仪表等领域的强有力工具。因此,开发高精度、抗干扰性强、低成本、工作可靠的数据采集装置是当前的迫切任务。尽管现阶段国内已有各种各样的数据采集模板可供选择,但在具体工程应用中仍感到有许多不足之处,尤其是它们的价格昂贵。所以我们在研 In recent years, with the rapid development of science and technology, microcomputer applications are becoming more and more widespread. The universal data acquisition device composed of microprocessors and A / D converters has become a strong field in scientific research, production process control and intelligent instrumentation Powerful tool. Therefore, the development of high-precision, anti-jamming, low-cost, reliable data acquisition device is the urgent task. Although a variety of data acquisition templates are available in the country at this stage, there are still many shortcomings in the application of specific engineering. In particular, they are expensive. So we are researching
