Research And Implementation Of Mobile Police Terminal System Based On MVP Architecture

As the scope of police work is more and more extensive in our country,the law enforcement work is gradually increasing,it has made the a higher requirements of the police efficiency,adaptability and work efforts.This article is based on the construction of the DongGuan Police Station's mobile police system.By combing the work of police officer in DongGuan,design and implement the terminal software system.The system consists of two main functions: Police Information Management and Police Handling.In the police information management,It achieves the functions of collecting,querying,and adding the information of population,vehicles,houses,units and places.In the police processing function,it achieve the functions of viewing and forewarning the message task,Performing the task and reflecting the situation under the different four work modes,location service management.The system is based on Android platform and runs on the police special tablet.Using the MVP architecture for the system design and development,it reduces system coupling and improve the system extensibility.The system uses the Web Service as the service support platform,and adopts the service interface provided by the police information service system.Through the Soap protocol,encapsulating the data into xml format and using encryption technology encrypt the data,to achieve the data communication between the client and the server.The system provides online access and offline access.In online model,the system communicate with the server through the wireless network.In offline mode,the terminal uses SQLite database for data caching,and SQLCipher for cache data encryption and decryption access.The establishment and implementation of the mobile police terminal system has improved the efficiency of police officers Largely.It could check and report the information in time and solve all kinds of events in a short time.The system has established a great environment for police officer and provided a harmonious life of the people.
