Design And Study On Police Intelligence Analysis System Based On GIS And Spatial Association Rule

Since 1949, Our country has attached great importance to the work of Public Safety. The state not only established a more systematic and complete security information management agency, but also invested a lot of manpower, material resources used for data collection work of police operations. The security information management and scientific research has made great achievements. However, for many reasons, China's public security information technology started late and has a poor foundation which was far behind the developed countries, Along with social economy's rapidly expand, the public security faced with day by day stern and the brand-new challenge, traditional security mechanisms have found it hard to complete the means to effectively guarantee public security. In limited of police circumstances, how to use high-tech measures to effectively analyze the situation of police intelligence, improve crime crackdown public security departments are the first thing to consider it. In the modern economic and social conditions, the Ministry of Public Security require dynamic management and the fight against crime, need to achieve "science and technology strengthening policing",enhance the public security system's unified command,rapid response,coordination of operations, the ability to combat crime and improve the efficiency of public security and surveillance detection levels, so they proposed construction of "Golden Shield Project"It was in this background to put forward a new project--"Police intelligence analysis system based on GIS and spatial association rule". Police intelligence analysis is the key step in City Emergency System, by which we can deal with emergencies properly, quickly, effectively in the critical moment, and reduce the loss in accidents. It concerns the safety of the people's life and property and the stability of society. The police intelligence analysis work urgent need to take the police sentiment information analysis evaluation as a method, take the science highly effective police service management as the core, and take the practical highly effective tactical decision as the goal to lead the police service to come to serve for the socio-economic development, achieves" the attack, the prevention, the service earnestly " this brand-new working pattern. The geographic information system is a tool which can analysis, process and solute the space geography information related question in the daily police service work and the public security actual combat, has played the very important role. Establishes the police intelligence analysis system based on the geographic information system is guarantees the Public security department fast, accurate, the image direction various police forces department to be able real-time, reasonable to the police forces dispatch and the processing key. Moreover, the public security service in the informationization construction's process, has accumulated a large number of population and complex the cases, those data were broad, which has concealed the useful information. Therefore we need to unify the service itself mechanism to explore a kind of new technology and find a reasonable digitized model. We can solve such difficult problem based on the correlation in space rule's data mining technology. With the help of technologies such as data warehouse, data mining and knowledge discovery, traditional intelligent analysis can get valuable information from massive data resource to make decisions. It make intelligent analysis of policing information became a realistic plan and promote modern policing towards intelligence-led.The police intelligence analysis systems construction goal is:take the public security interior network as backing, "Three-in-one integrated Emergency Command System" and other information system as foundation, taking "the human, the thing, the matter, the organization" five essential factors which public security profession are interesting as well as the public security as evaluate objects, establishing variety informational analysis models to provide promptly, accurate analysis data information for all levels of police officers, for the purpose of instructing policeman's routine works such as go on patrol, monitoring, propaganda, education to increase the detection rate.This research's primary coverage is the evaluation model which through the investigation and study, in the definition public security domain needs, utilizes the connection rule as well as the correlation in space rule data mining technology fully to the magnanimous police service demographic data, the case data carries on the classified excavation, provides the data foundation for the establishment evaluation model. Using the GIS map demonstration mechanism as well as the spatial analysis technology in above the existing police service system's foundation, completes the network distribution and the networking movement police sentiment evaluation analysis system. Through with the population system, the police service synthesizes platform case system's docking, we carry on the crime map and the population management's form the metasynthesis. Using the new technical analysis method, carries on the collection to each kind of data, to compile, the statistics, and will evaluate the thought to survey the crime information the way, reflects intuitively on the electronic map. It is advantageous in police has the goal, to have the goal instruction society surface public security patrol prevention and control, reduces the crime space vigorously, the pressure drop illegal crime, thus has formed one kind of multiplex system. In addition, we also the related public security operational channel and the police service geographic information system will carry on the connection conformity, will realize the pinpointing demonstration, the synthesis on the electronic map to inquire and to evaluate the analysis, forms synthesis application which the trans-region, the cross police will plant, will achieve the policy-making direction visualization, to hit the prevention and control integration, the information application intensification. For the promotion battle efficiency, enhances the decision analysis the scientific style to provide the powerful support. Moreover, the article has also studied the police sentiment analysis system's reliability, guarantees the establishment safe effective police service information system.It is a significance research field for data mining technology and GIS. The data mining technology and GIS which applied in Police analysis system were very important for Public security informationization. These were also a key technology to realize Police analysis System's functions. For the angle of Public security informationization:Data mining technologies such as association rules analysis technologies,GIS spatial analysis which applied in police analysis system identifies relational data effectively. The Police analysis system can give instruction quickly to police when accident taken place. Policy department can response much more quickly to deal with emergency with the help of data mining technology. For the angle of application: through the network to solve the traditional delayed analysis in order to ensure that the analysis of the data can reflect the situation of police intelligence. It will be rapid, objective, accurate, flexible to display dynamic security information and easy to find out the rules and characteristics of cases, in order to combat and prevent the provision of technical support and decision-making basis. It was beneficial to reduce the day-to-day grass-roots police statistics and improve the degree of accuracy and sharing.The contents of the master's thesis is divided into 6 chapters, are as follows:We analysis the police data with data mining technology and establish a police data mining module. We use spatial association rules to analysis the existing of police data, judge the crime and to ensure the practicality of the system.The existing police analysis system is based on the C/S pattern, and analyzes the result is the report data which is arid and complex. But the article proposed that the system based on GIS, using map's characteristic direct-viewing, clear demonstration evaluation analytical data effect, enhanced case solving rate, provided the image appropriate rationale to police organization.We apply GIS to the public security police's practical work, and with other police service work system connection, obtained a deeper level the auxiliary policy-making benefit.
