农业物联网场景模拟仿真系统的研究与实现

摘要

IoT are fused together by a number of new IT technology system ,known as the world's third wave of the infor-mation industry after computer and the Internet .The application of agricultural IoT technology is the needs and direction of the development of modern agriculture .With the synthesis of the agricultural IoT application , an abstract model for IoT application scenes based on a concept of three-worlds ( i.e.physical world , sensing world and simulation world ) was proposed and also used object-oriented method to model and analysis of the three-worlds’ objects.On this basis, the event scheduling method and JavaSim simulation technology were adopted to develop the system .Trial shows that agri-cultural IoT scene simulation system is generally applicable and extensible .%物联网是由多项信息技术融合而成的新型技术体系，被称为继计算机、互联网之后世界信息产业的第三次浪潮。农业物联网技术的应用是现代农业发展的需要，也是现代农业发展的方向。为此，通过对农业物联网应用业务的综合归纳，提出了基于“三个世界”（物理世界、感知世界、和仿真世界）概念的农业物联网应用场景抽象模型，并运用面向对象方法对“三个世界”中实体属性进行建模分析。在此基础上，采用事件调度法的仿真策略和JavaSim 的仿真技术对农业物联网场景模拟仿真系统进行开发。应用表明，该农业物联网场景模拟仿真系统具有良好的适用性和可扩展性。
