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。
Based on the model of nutrient salt and its influencing factors, based on the ARM Cortex-M0 + kernel and GPRS technology, Visual Studio 2010 and Access database are combined to develop the nutrient predictive analysis system. The system’s data transmission using Modbus protocol, easy to compatible. Users can select nutrients and their related factors as needed. Nutrient predictive analysis system can remotely analyze the trends of nutrients and their related factors, and predict the relative errors of nutrients. In addition, the system has the scalable function, that is, according to the characteristics of the waters, choose different prediction models to expand its scope of application, but also provide a new platform for on-line detection of nutrients.
