Application And Research Of The Cloud Platform Solution Based On GPS

The trend of China’s aging population has been inevitable. According to a report by the relevant institutions and research, nearly ten million childless families will appear in our country.Issues related loss of pension alone have been relevant departments attach great importance to."3without" the old man,"supporting" the old man of rural endowment problem solving is the basic goal of the ministry of civil affairs by the state that has got a basic solution through the centralized and decentralized approach to make the lives of these people.lt becomes more and more prominent that the old men can not get effective monitoring.This paper proposes and implements a combined wristband GPS terminals and cloud platform.The scheme using GPS technology to help guardian daily monitoring for the elderly makes the difficult issues of the empty nest elderly guardianship get better.In allusion to the problems that old people can not use the mobile phones,it is easy and convenient for the emergency call operation to set a key on the number and location of terminal SOS function by the guardian in advance on the platform.Using the cloud platform combined with positioning terminal electronic fence function can get an early warning from the old men in the danger zone.Through the cloud platform providing the navigation function,the old men getting lost can have a routine to their home and the old men who need to travel can arrive at the destination smoothly.Due to that GPS can provide the measured on the object on the earth longitude,latitude,speed,acceleration,direction data and etc.,the prediction of the daily actions of the old men(such as whether to fall) has a certain value. At the same time the cloud platform can store the daily informational data of the old men and can reproduce the trajectories of the old man nearly by correspondingly processing their historical data.Storing the old men’s medical history can provide a communication platform for the guardian who have the same old men.Cloud platform adopts NGIX+PHP+MYSQL architecture, REDIS database server, C#language implementation of the communication middle ware.By resident memory to persistence operation of MYSQL,REDIS database server makes common data query operation more quickly.Positioning terminals and server communication is implemented by the Socket and the communication of a message format adopts the HTTP protocol.It is suitable for the cloud platform to use the NGIX,which is a server manager that is used to satisfy the big data traffic system designed by Russia.In addition the cloud platform choose level3unit structure.The level1unit is responsible to handle the login operation of the users letting users successfully logged in transferred to the corresponding secondary units.Until the secondary units process the users’s data request,the level3can store the detail users’s information.So it can reduce the storage and the pressure on the level unit and the secondary unit in processing data.
