The Design And Implementation Of APP Intelligent Tracing And Guardian Base On Android Platform

Mobile applications with the popularization and development of Internet technology and plays a more and more important role in our daily life.Every year some vulnerable groups lost also frequently appeared in our life.But the protection and search means was single and inefficient makes for those already lost people was very hard to get it back.For these problems,some wearable and location card products have been development,for lost,these products added location function, which provides clues to find missed people, But it's not enough to guardian.In view of these problems.designs a set of more flexible guard mechanism and search mode system in this thesis.In the aspect of guardianship provides the monitoring function based on the geographical position.In order to ensure that the monitoring location can real-time access and immediately back to the guardian.at the same time, in order to ensure that the release of information can be the first time to reach the target user's mobile phone.In this thesis.design a double service model to guardian App and the broadcast and unicast mechanism of message push is designed also. In order to achieve that notice in a missing-persons column be known by more people and receive more feedback.This article provides the information release platform for search missing-persons,in this platform, users can publish any notice and this information will be the first time broadcast to all online users.In order to support the stability and real-time performance of front data,in this thesis, a corresponding server is designed to manage the data and data logic between users.In view of the possible existence of the push, provides three modes to achieve the broadcast push, specified account push and according to these modes the corresponding data transmission protocol is designed. Mainly solve the following problems:Aiming at the problem before the lost,designs the electronic fence and alarm to realize remote monitoring and control in this thesis.Define the range of activities and calculate the distance to the target in real time.when the position of the target and the position of the original set difference Greater than the original set value then a warning message about target's position would been send to custody.At this time, the guardian can be based on the information sent to remind the timely warning or immediately start looking.This is a great liberation for both the guardian and target,the monitor can carry out his work and study,while target get real time protected.Aiming at the problem after the lost,this thesis designs a set of interface to obtain the real-time user's location, and the location data back to his guardian.When the target was lost the guardian could find them according to the return data.Of course the guardian can also timely for his protection object track view, to clear the position of his know protection object in real time.In addition, also designed a mechanism to enhance the search for found the missing efficiency in this thesis.Any release a notice in a missing-persons column Will be sent to all users in the form of broadcast,users according to the clues can be timely to help others.Finally,the application are tested based on the functional requirements and non functional requirements to verify that meets the requirements and analyzed the test result.As the analysis results show that the application is stable, the system compatibility is good, and all the functions proposed in the demand are realized.The last important is that it owned better function systems than the original guardian equipment,and has comparatively higher practical value also.
