With the popularization of smart phones among students,Students with younger age trend in primary and middle school use smart phones to surf on the Internet becoming more general.Meanwhile,in the day of fast development in mobile intelligent terminal,facing with the complex Information on the Internet,primary and middle school students who have low self-control ability and poor judgment are easily besieged by the negative Information on the internet.On the one hand,this problem severely impacts students' study and campus life and mental health.On the other hand,more cost and burden will be given to schools and parents in the case of students' safety and connection to students at any time.Parents have to prepare smart phones to kids.However,school usually take measures in confiscation or hand in smart phones to students and forbid them to take.Thus,conflicts among students' usage,parents' concern and schools' management cause problems in management and connection for solving the problems concerning about smart phones among students,parents and schools.By designing and implementing student mobile phone control system,we will let students focus on study during the school time and help them to use smart phones with green,healthy and reasonable way.The main contexts of this thesis are as following:(1)In accordance with the practical survey on the correct way to use smart phones among students,parents and schools' concern in studying and living,this thesis analyzes the functional and nonfunctional demand to this system.On the basis of demand analysis,the overall design,detailed design will be completed.(2)In accordance with the survey on the demand of this student mobile phone control system,for facilitating parents and school to use,the control end product should be released on H5 and We Chat applet.For achieving this goal,I research anduse uni-app to complete research and development work and deployment work on management end.(3)On the basis of flutter frame Android plug-in mechanism,by researching and using flutter front end UI frame to finish the most central background processes keeping alive for mobile phone control system on Android platform and implementing actual or timing management strategy to students.Meanwhile,for the sake of data security of Android,the flutter framework Android plug-in mechanism is used to finish the research and development work on ground flutter encryption library. |
