In the production process, the system can be applied to field production process parameters for collection, monitoring and recording. To improve product quality and reduce cost mean of information. In scientific research, data collection and application of data processing system will be a lot of dynamic information. Blink time to study the physical processes powerful tool, as well as access to scientific mysteries of one of the important means. In short, in whatever field, data acquisition and data processing systems are widely used. The economic impact is increasingly larger. In modern society, production and people39。s daily life, SCM has wide application. SCM functional integration with the development, application areas have gradually from the traditional control, to control the expansion, data processing and digital signal processing (DSP, Digital Signal Processing), and other fields. Sunplus 16bit MCU is to adapt to this development and design. Key words: Data Acquisition 。Data Processing。 Sunplus61內(nèi)蒙古科技大學(xué)畢業(yè)設(shè)計(jì)說(shuō)明書（畢業(yè)論文） I 目 錄 摘 要 .........................................................................................................................................
