面向“端云用”综合开发训练的物联网虚拟仿真设计

IoT Virtual Simulation Experiment Design for Terminal-cloud-application Integrated Development Training

随着物联网的广泛应用,物联网技术学习者规模日趋庞大,迫切需要一个无须硬件即可学习物联网开发技术的实验系统。江苏大学结合物联网“端云用”架构,选取Arduino、物联网云、微信小程序设计实践内容,设计了一个面向“端云用”综合开发训练的物联网虚拟仿真实验系统。学生可以采用虚实结合方式,在虚拟场景中创建Arduino物联网设备,自主编程将虚拟设备接入公有云,进而自主开发微信小程序,实现真实手机对虚拟设备的感知与控制。在此基础上,以农业大棚物联网典型应用场景为例,通过虚拟仿真实验,让学生真实体验并理解应用物联网技术解决农业领域生产问题的全过程。

With the wide application of Internet of Things(IoT)technology,the scale of IoT learners become more and more enormous.Currently,the learners urgently require a novel experiment platform,which can provide the integrated IoT development training while without any hardware.Facing this requirement,Jiangsu University considers the IoT typical architecture of"Terminal-Cloud-Application",then selects the mainstream technologies of"Arduino,IoT Cloud and WeChat Mini Program"to design a IoT virtual simulation experiment.This experiment adopts"Combination of Virtual and Reality"experimental method.During the experiment,the learners can create virtual Arduino IoT devices,connect the virtual devices to public IoT cloud by self-programming,develop WeChat mini program on their own phones,then remotely sense and control virtual devices through WeChat mini program.Furthermore,three IoT scenarios of agricultural greenhouse with random environment parameters are developed in this experiment,within which more than 20 available vegetables for planting are provided.Through simulating the planting process,the learners can understand how to use IoT technology to solve the realistic agricultural problems.
