The Application Research Of Mobile Police System

With the constant development of science and technology, the department of public security also takes more and more attention on strengthening polic work with science and technology. Along with Golden Shield project's generally started, a series of public security foundation database,such as resident population, temporary residents, focused population, fugitive database, fingerprint system, stolen or robbed vehicles and driver information and so on, has been continually improved, public security internal network applications have been expanded, but the existing public security system has been unable to adapt the present public security work. As public security policemen carry out police service work, they can only speak with unit left behind colleague through communication such as radio, cell phone to inquire and verify data. This original model has apparently been working behind the development of times, and public security policeman needs a advanced, easy operation, mobile platform to meet the policesecurity work development.Combining computer technology with wireless communication technology, the mobile phone and J2ME technology are used to develop a public security police system for public security patrol. Through the wireless communication, traffic policeman and patrolmen can inquire people and objects out of limited time or region very first time and deal with illegal phenomenon to realize palmtop functions with simple use,portability and work of practical completion.A prototype of multi-layer structure of wireless application system is used in present paper uses, including Web server design, wireless client interface design, communication module design, RMS management module design, database design and so on. Hierarchical system architecture, J2ME architecture, hierarchical technologys, such as RMS, MIDP are analyzed systematically. Then it has carried on the deep analysis and research of J2ME platform's system structure, configuration and a summary table on the norms, RMS and the networking technology. Using the J2ME technology advantages in mobile aspect, the design and implementation methods of key parts of this system are given. a public security traffic policeman and patrolmen mobile police system is developed, and a integral mobile phone application program development is completed, made it to be a bright spot in strengthening police work with science and technology.The development and application of system enhances greatly sharing level of public security information resource, and lay a foundation for the construction of public security information superhighway, also makes a beneficial exploration for trengthening polic work with science and technology. The system runs on a computer, realizes network access and correct test. This system has the enhancement on transparency, flexibility, highly efficiency, expansion, satisfies basically the routine work demand of traffic policmen and patrolmen.
