The Police Information System Base On The Wireless Communication System

With the rapid changes in technology, more and more attention to high-tech public security department in the role of police work. With the Golden Shield Project applications, basic database security(police basic date base) the establishment and improvement, the popularization of the internal network security, the traditional mode of public security system can not meet the current needs and development. Police officers in their daily work, still stuck in by radio, telephone and other communication tools and general staying in the flat mode of communication with colleagues, their efficiency is obviously not keep up with the rhythm of the times. Police urgently need an advanced, portable, easy to meet the information platforms work. In this paper, WAP technology with advanced research and development based on the premise, successfully developed and designed a wide coverage, portable police system. This system is based on public security network for the support, the use of advanced mobile communications technology as well as the current database system has been formed through the human-computer interaction, access to information, in order to ensure that data needed to police the scene when Alarming.Paper’s main work includes:1. And characteristics of GPRS network technology as the platform, using the WAP technology contains security WTLS protocol system to ensure the stability and security of the information transmission, developed and designed a successful application of WAP technology of police system, the system in wireless operation at the same time also has the characteristics of mobility.2.On the basis of thorough analysis and research put forward a kind of structured data and semi-structured data mapping algorithm, is advantageous for the related data information quickly and easily save and extraction.3.Regarding the public security system of mobile police special requirements on the transmission of data security, taking into account the characteristics of the wireless communication technology applications, the use of already mature for wireless data communication network hybrid encryption algorithm, in order to ensure that the design of the system has greater security and stability.Research and development and application of the system, is not only beneficial to promote the improvement of the public security information sharing, and to promote the rapid development of the public security information highway and construction, help to promote the public security system for the development and application of science and technology. The current application of network communication technology usually has the characteristics of stability, security, fast, so system framework based on the technology and create advantage of further expansion of space of late. The system has a high degree of generality and can be applied to multiple departments, is not just limited to the public security department.
