摘　　要：在构建营养盐与其影响因子模型的基础上,基于ARM Cortex-M0+内核及GPRS技术,结合Visual Studio 2010和Access数据库,开发营养盐预测分析系统。该系统的数据传输采用Modbus协议,便于兼容。用户可以根据需要选定营养盐及其相关因子,营养盐预测分析系统能够远程分析营养盐及其相关因子的变化趋势,以及预测营养盐的相关误差。另外,系统具有可扩展功能,即根据水域特点,选择不同的预测模型,扩大其应用范围,也为营养盐在线检测提供了新的平台。On the basis of constructed models of nutrients and their impact factors, and combined with Visual Studio 2010 and the Access database, we develop a nutrient predictive analysis system based on ARM Cortex-M0+ core and the technology of GPRS. In the system, data transmission adopts the Modbus protocol, which is easy to be compatible. Based on nutrients and the relevant factors selected by users, the nutrient predictive analysis system can analyze the trends of nutrients, relevant factors, and relative errors of predictive nutrients. In addition, the system has extension functions, which are facts that we can select different predictive models based on characteristics of the water, enlarging application ranges, which also provides a new platform for the online detection of nutrients.
