数据采集是工业现场重要的一个环节,选择不同的传感器可以对不同的信号量进行测量,根据对采集的数据进行处理和分析,可以更加精确地了解现场工况。本文以STC89C52RC单片机和MAX187串行AD芯片为核心,并结合CD4051八选一多路开关,设计了一个高精度的温度数据采集系统,实现了多通道的数据采集功能。
Data Acquisition is an important step in industrial field, and the collected data that measured by different sensor should be processed and analyzed, in order to understand the practical conditions exactly. This paper designs high-precision data acquisition system based on microcomputer STC89C52RC, series AD chip MAX187 and multi-channel electronics switch CD4051, which realize the multi-channel data acquisition function and suitable for temperature measurement systems.
