基于LabVIEW的监测及预测系统的设计

Design of Monitoring and Forecasting System Based on LabVIEW

基于虚拟仪器设计了马铃薯田间气象信息的实时监测及晚疫病的流行性、灾变预测系统,该系统对气象信息包括温度、湿度、降雨量等进行采集、显示、处理分析及存储,通过灰色预测模型实现预测.介绍了系统软、硬件的功能与设计,并且对基于多变量的灰色预测模型GM(1,n)的流行性预测和基于GM(1,1)的灾变预测进行了重点研究.实验研究表明,所设计的系统预测准确率较高,具有实用价值和现实意义,可进一步推广.

Based virtual instrument the system of potato field meteorological informationts realtime monitoring and late blightts epidemic and disaster prediction was designed. The sys- tem can collective（temperature, moisture, rainfall ） ,display ,process and storage the mete- orological information , and achieve prediction by grey prediction model. This paper intro- duces the systemrs hardware and software, function and design, Based on multivariable grey model GM （1, n）＇s epidemic prediction, based on GM（1, 1）＇s disaster prediction was re- searched intensively. The experiment shows that the accuracy rate of predicting is high, and that it has practical value and realistic significance and that it can be extended widely.
