Design And Implementation Of Cross-platform Mobile Application For The Internet Of Things

With the rapid development of mobile Internet,mobile development platform mainly USES Android,iOS,Windows Phone,its technology is not compatible with each other.The development of repetitive applications on different mobile platforms adds to the cost of the enterprise.At present,farmers mainly rely on experience to produce crops,unable to monitor the growth of crops in real time 24 hours.According to the above problem,this paper put forward based on Web front-end technology development for cross-platform mobile application of the Internet of things,to get farmers to use all kinds of mobile phone terminal real-time monitoring and remote control of crops growth environment and the production process.This paper first introduces the Web front-end language HTML5,CSS and JavaScript.Through the comparative analysis of domestic and international mainstream cross-platform development framework and mobile front-end development framework,choose to Ionic as front-end development framework,and choose to PhoneGap as a cross-platform framework,and the system architecture,cross-platform principle and realization principle and local bridge in-depth research.After that,the paper introduces the structure of the internet of things system and the role of mobile terminal application in the system of agricultural Internet.Then,this thesis for the Internet of things,cross-platform mobile application design,through the UML sequence diagram is constructed to design sensing detection,remote control and video image,parameter setting,the user use cases.In the design of the multi-platform mobile application design for the Internet of things,the design of the interface is based on the basic layout mode of header,content and footer.Then,this paper introduces the realization method of the cross-platform mobile application for the Internet of things.On the interface implementation main using HTML and CSS page and layout,use JavaScript to implement the business logic processing,through the Ionic routing management to implement the footer navigation bar button switch interface,using Ionic lattice grid layout system implementation;Sensing and remote control can achieve its functions by interacting with the server.The video image and parameter Settings call the playback plug-in and audio plug-in through PhoneGap to implement video playback and alarm playback.Finally,for the Internet of things,cross-platform mobile application successfully packaged into iOS and Android corresponding installation package,through the test on the iPhone 6 s and millet mobile phone has a good stability and reliability in the process,to provide farmers with convenient,fast and intuitive service,has the good market application prospect.
