Problems solved by technology

Both forms have disadvantages. The form of polling and reading database data has poor timeliness and cannot fully guarantee the real-time performance of the data, and there is a certain delay. However, in the case of emergency emergencies in the police geographic information system, the data timeliness is extremely important
Timeliness can be solved by docking GPS real-time messages based on IE browser control form, but there is a compatibility problem. The control form can only be loaded under IE browser, and other browsers cannot load the control, resulting in the limitation of GPS real-time message docking

Abstract

The invention discloses a patrol freezing point determination method based on a police geographic-information system. The method includes the steps that the police geographic-information system (PGIS)receives GPS information in real time; according to the GPS information received in real time, a patrol area range is calculated; according to the GPS information received in real time, superpositionand aggregation calculation is conducted on patrol area data, and alarm frequency in an area is calculated; according to the calculated alarm frequency in the area, the weighted value of the area iscalculated; according to the calculated weighted value of the area, the calculated patrol area range is revised; according to the revised calculated patrol area range, spatial overlay analysis is conducted on the revised calculated patrol area range and a car patrol area range acquired through a GPS in real time, and a heat map is generated; spatial calculation is conducted on the generated heat map, and a patrol area freezing point is obtained. The patrol freezing point method based on geographic information of the PGIS can achieve high performance calculation of police strength freezing point space.

Description

technical field [0001] The invention relates to the field of geospatial data analysis, in particular to a method for determining a patrol freezing point based on a police geographic information system (PGIS). Background technique [0002] The police geographic information system (PGIS) is used to build a dynamic and efficient flat service command system. First, through the real-time positioning of alarm information and street dynamic police force on the map, the visualization and flattening of command and dispatch can be realized, and real-time Deploy the police, dispatch the police quickly, and deal with the police quickly. The second is for police situation analysis. Through technical means such as four-color early warning and police situation hotspot analysis, it can timely control the trend of police situation and the law of crime occurrence, and dynamically adjust the level and plan of patrol prevention and control. [0003] In the existing technology, PGIS realizes sp...
