| 摘 要： | 在粮食仓储过程中，通过温湿度传感器、图像传感器采集到的温湿度、图像的实时数据，经过信息处理算法的变换和特征提取，得到具有不同特征信息的虚拟多传感器数据，采用D-S证据理论对数据进行信息融合，对粮食在仓储过程中的霉变、虫害等粮情进行动态预测分析，当发现有不良变化时，该系统能够及时发出预警信息，以保证粮食的储藏安全。

| Abstract: | The temperature, humidity, image data had been obtained by sensors in the grain storage period.The virtual multi-sensor information with different characteristics can be obtained after transformation and feature extraction.Then, the information integration is achieved by Dempster-Shafer evidential theory.Mildew and pests in grain can be forecasted in the grain storage period.When adverse factors occur, this system can send out warning information to ensure grain safety. |
