A Context Model for Mechanical Ventilation in Grain Storage

In order to improve the effect and the efficiency of the mechanical ventilation in grain storage, a context aware method is proposed. The context meta-model is defined which builds the basis for context modeling. The context model for mechanical ventilation in grain storage is built, which had full consideration of the ventilation purpose and the lifecycle of grain storage. The feasibility and the correctness of the model is verified with the context aware service system, which can receive the context information of the granary to figure out the real situation and make the ventilation plan accordingly.
