一、引言本文介绍的智能化测温仪表以美国Intel公司生产的MCS-48微型计算机系列中的8039单片微型机作为整机核心部件,利用其指令功能强、指令执行周期短、外部线路简单、有直接I/O接口能力、能进行适量的数据处理和中断处理等特点,在软件控制下,可以进行测温通道的切换、非线性补偿、数字滤波和超限报
I. INTRODUCTION The intelligent temperature measurement instrument introduced in this paper takes the 8039 single-chip microcomputer in the MCS-48 microcomputer series produced by Intel Corporation in the United States as the core component of the whole machine. Its instruction function is strong, the instruction execution cycle is short, and the external circuit is simple , Has the ability of direct I / O interface, can carry on the right amount of data processing and interrupt processing and so on. Under the software control, it can switch the temperature measurement channel, nonlinear compensation, digital filter and over limit
