Research On Key Techniques Of Internet Of Things Remote Monitoring Based On Mobile Mode

At present, IOT (Internet of Things) technology develops dramatically, the scopeof research gradually extends to all spheres of daily life and national economy, moreand more devices also join in the Internet of things. The use of intelligent terminal fordata acquisition in environment parameter monitoring scheme has been applied inmany fields, such as field monitoring, environmental monitoring, aquaculturemonitoring, etc. Since traditional ways of monitoring are affected by fixed monitoringterminal equipment, timeliness is bad, the management can realize monitoring only atthe specified control room or with the computer system under wide band coverage,flexibility and monitoring effect are not ideal.In recent years, the mobile intelligent terminal technology and the developmentof3G/4G communication technology offer possibilities for mobile terminalapplication in the IOT remote monitoring system. Friendly interface, abundantfunctions and good user experience of intelligent terminal provides promotion for theapplication of remote monitoring system under mobile mode with opportunities. Torealize the IOT remote monitoring system under the mobile mode, major problemswhich need to break through include communication protocol between the mobileterminals and other equipment within the Internet, information transmissiontechnology, information processing technology, information security and theimprovement of terminal system users’ experience.In this paper, the Android mobile mode in the monitoring system based on IOTand Web Service technology which realizes the communication between client andserver are researched. Combined with the granary monitoring case, the monitoringenvironment parameters are determined and the intelligent sensor installation layoutis designed through the analysis of the specific application environment, the keytechnologies such as the information transmission technology, communicationprotocol and system security are thoroughly researched, what’s more, the systemdatabase is constructed and the whole system solution is designed. The UI interface ofeach module is designed, the sequence diagram is used to design the interactionprocess between each module. The key technologies of the IOT remote monitoring system in mobile mode include:1) The data processing technology to realize the datacleaning, data extraction and statistics;2) The JSON data protocol to realize the lightload and standardization of data;3) The data encryption technology to improve thesystem security;4) The asynchronous loading technology to realize the terminal dataflow loading. In this paper, the detection method of duplicate records in data cleaningis improved; the method of data extraction and statistics is studied and implemented;the scheme is optimized based on asynchronous loading to shorten the image fileloading time.Finally, the adopted key techniques are applied and verified in the case and theapplication is installed on the mobile terminal for function and performance test toprove that the use of the key technologies improve the system’s stability, fluency,retardation and reduce the energy consumption, which is a thorough and usefulresearch and exploration for mobile terminal application in the IOT remotemonitoring field.
