随着计算机技术的飞速发展,人们对测量仪表的性能和智能化要求也相应提高。不仅要求对测量仪表采集的信息进行分析和处理;而且也要求对一些数据进行补偿和修正。完成这些功能,目前最有效的方法就是利用计算机技术。一般说来,测量仪表在生产现场所采集的信息,大部分是模拟量信号。对于模拟量信号,必须通过A/D转换器,转变成数字计算机或微处理器能够接受的数字量信号。目前国内批量生产的 With the rapid development of computer technology, the performance and intellectualization requirements of measuring instruments have also been raised accordingly. It not only requires the analysis and processing of the information collected by the measuring instruments, but also requires some data to be compensated and corrected. The most effective way to accomplish these functions is to use computer technology. In general, the information collected by the measuring instruments at the production site is mostly analog signals. For analog signals, it must be converted to a digital signal acceptable to a digital computer or microprocessor via an A / D converter. At present, the domestic production
