Emergency Rescue System Based On Information Driven

With the rapid development of medical care,people's life span has increased.However,at the same time,the number of deaths caused by accidents is also growing,Especially for the high-risk groups such as the elderly,to whom sudden abnormalities may happen,if they are not rescued immediately,tragedies will occur.It is precisely because of these pain points and difficulties that the escort work of the elderly is particularly important.With the rapid development of mobile communication technology,smart phones have become an indispensable part of people's daily life,and the rescue service based on smart phones has been paid more and more attention.But the traditional mobile rescue service which can easily lead to the late rescue can't effectively track the location of users.In addition,it is easy to cause instability or even collapse of the system of the traditional software architecture when a large number of users request at the same time.To solve the problems mentioned above,this paper uses cloud computing,then it runs emergency aid service applications on Android client and cloud platform.In order to ensure that the elderly and other special groups can get timely rescued when sudden abnormalities occur,this paper proposes an "emergency rescue system based on information driven"."Information-driven" is to use the information technology which has been developing rapidly to ensure that the elderly and other special groups can quickly send out information when they encounter unexpected situations.Rescuers can quickly determine the location of the target user after receiving rescue information and then launch quick rescue.The main research contents of this paper are as follows:1.The emergency rescue system is designed.This paper first analyses the requirement of the whole system from the functional and non-functional perspectives and then designs the overall architecture of the system,completes the design of the communication protocol between client and server,and finally designs the functional modules of the system in detail.2.The emergency rescue system is realized.In order to ensure that users can get timely rescue when encountering unexpected situations,this paper mainly starts from two aspects: "emergency call" and "emergency aid".Emergency call is to ensure that users can send out the rescue information quickly when sudden abnormalities occur.This paper designs a "one-click rescue device" to solve the problem of emergency call.The most important thing in emergency aid is to quickly determine the location of the rescuers.This paper combines GPS positioning,WIFI positioning and base station positioning to ensure that rescuers can accurately determine the location of the target users and then launch quickly rescue.3.The emergency rescue system is tested.In order to ensure the stability and efficiency of the system,this paper mainly tests the whole system from the functional and non-functional perspectives.In terms of functionality,the black-box testing method is mainly used to test the various functional modules of the system.As to the non-functional perspective,the security,compatibility and client interface of the system are tested.4.In order to solve the problems brought by traditional software architecture,this paper deploys emergency rescue service on cloud platform and then uses load balancing mechanism to distribute service-terminal resources evenly to ensure the stability of the system when a large number of users access it at the same time.
