Design and Implementation of the Lost-and-Found System Based on Amap API

Abstract

The lost-and-found information management system, as an important part of the social public service system, has its special significance. With the change of traditional lost-and-found pattern, the process of lost-and-found has fallen into the dilemma of “people looking for things, things for people” and the proportion of lost property retrieve is less than 10%. The rapid development of location service, 4G communication technology and intelligent terminal has provided a new way to establish a lost-and-found information service system with GIS functions, which effectively solved the problem of “where” in the process of lost-and-found. By the integration of Android system and interface technology, focusing on the actual needs, technical architecture, functional architecture and database structure of the system have been designed. Using the C/S architecture and MVP development model, the lost-and-found system based on Amap API have been implemented subsequently. Whereafter, the functional test and performance test were carried out. Through testing and using, each module of the system achieves the desired design effect. The client takes only 12.75ms<16ms to load a frame image and the system is fluent and stable. By means of location service and spatial analysis methods, users enable to release, browse, search and share lost-and-found information conveniently. The organic integration of location service and lost-and-found models has made the process of lost property retrieve more efficient and faster.
