在实时控制和各种智能仪器仪表中,微电脑起着指挥调度、信息的采集、处理和控制等作用。其中,对于信息的处理,通常是将实时采集的信息进行 A/D 转换并经适当处理,然后将此“采样信息”与存在微电脑内部的“标准信息表”进行比较(即查表),从而获得被测信息的有关定量数据。显然,这张被查询的标准信息表是整个系统的唯一计量标准,此表质量的好坏,直接影响着整个系统的性能指标。由于目前大多数采集信息用的传感器其输出特性是非线性的,再加上环境(如温度、湿 In real-time control and various intelligent instruments, microcomputer plays the role of command and dispatch, information collection, processing and control. Among them, the information processing, usually the real-time collection of information A / D conversion and proper treatment, and then the “sampling information” and the existence of microcomputer internal “standard information table” to compare (that look-up table) Obtain the relevant quantitative data for the information under test. Obviously, this is queried standard information form is the only measure of the entire system, the quality of the table quality, directly affects the performance of the entire system. Since most of the sensors currently used for collecting information have non-linear output characteristics, together with the environment (such as temperature, humidity
