Applications of Data Acquisition Based on A/D Converter and Least Square Method
Jiang Liang-zhon · Microcomputer Information · 2009
The data what the monitoring equipment monitors in the industrial sewage treatment process often outputs through a variety of analog signals,but these analog signals that must converter digital signals by analog-to digital converter input computer or data acquisition device.For this reason,this paper gives a design which is based on TLC2543 Serial A /D converter.It implements ana-log to digital for monitoring data,and meets the need for the low-cost、low error and strong anti-interference capability,and the out-put data is amend by the least squares method algorithms to achieve accuracy requirements for the organic pollutants monitoring data in the environmental part.
