Problems solved by technology

[0004] At present, there are still some deficiencies in the analysis methods of using remote sensing technology to assess the occurrence and development of violence and terrorism: First, there is a lack of analytical methods with theoretical basis to build evaluation models, which leads to the low reliability of situation analysis results and is difficult to assess. As a powerful basis for coping with complex situations; second, there is a lack of comprehensive and objective evaluation indicators, and there is no targeted consideration of factors and possible impacts on the security situation in key prevention and control areas; The investigation results and human factors are taken into account, which affects the accuracy of the evaluation results; fourth, too much manual intervention is added, and it lacks timeliness in emergency situations

Embodiment 1

[0036] Embodiment 1 of the present invention provides a security situation analysis method, figure 1 It is a schematic structural diagram of an index system for a security situation analysis method provided by an embodiment of the present invention. The security situation analysis index system 1 includes four first-level indicators: vegetation information 10 , road information 20 , water resources information 30 and house construction information 40 . Based on the factors that affect the security situation in key areas and the aspects that may affect them, the selection of indicators is carried out in combination with the objectivity and operability of the evaluation indicators. Under this principle, each first-level index has a second-level index, which are: vegetation Euclidean distance 11, vegetation area 12, vegetation coverage 13, vegetation type 14, road Euclidean distance 21, road width 22, road grade 23, river Euclidean distance 31, river width 32, river depth 33, hous...

Embodiment 2

[0075] An embodiment of the present invention provides a security situation analysis device, see Figure 7 Shown is a schematic structural diagram of a security situation analysis device provided by an embodiment of the present invention. The security situation analysis device includes: a data input module 71, an index construction module 72, a spatial analysis module 73, a hierarchy analysis module 74 and a security situation module 75, The functions of the above modules are as follows:

[0076] A data input module 71, configured to input data such as remote sensing images obtained into the security situation analysis device;

[0077] An index construction module 72, used to construct an index system for the security situation of the target area;

[0078] Spatial analysis module 73, for generating the raster map of each index in the index system;

[0079] Hierarchy analysis module 74, for calculating the weight value of each index in the index system;

[0080]The security ...

Embodiment 3

[0084] see Figure 8 , the embodiment of the present invention also provides another security situation analysis device, including: a processor 80, a memory 81, a bus 82 and a communication interface 83, the processor 80, the communication interface 83 and the memory 81 are connected through the bus 82; the processor 80 Executable modules, such as computer programs, stored in the memory 81 are executed.

[0085] Wherein, the memory 81 may include a high-speed random access memory (RAM, Random Access Memory), and may also include a non-volatile memory (non-volatile memory), such as at least one disk memory. The communication connection between the system network element and at least one other network element is realized through at least one communication interface 83 (which can be wired or wireless), and the Internet, wide area network, local network, metropolitan area network, etc. can be used.

[0086] The bus 82 can be an ISA bus, a PCI bus or an EISA bus, etc. The bus can...

Abstract

The invention provides a security situation analysis method and device and relates to the field of security technology. The security situation analysis method is implemented based on a pre-establishedindex system. The method comprises the steps that a remote sensing image of a target region is acquired; information of first-level indexes of the target region is extracted based on the remote sensing image; the target region is divided into a grid graph with (N-meter x N-meter) meshes being units; data of second-level indexes subordinate to the first-level indexes is extracted from the information of the first-level indexes; weights of the first-level indexes of the current mesh units and the second-level indexes subordinate to the first-level indexes are acquired; the data corresponding tothe second-level indexes of the current mesh units and the acquired weights are utilized to calculate security indexes of the current mesh units; and a security situation map of the target region isdrawn according to the security index of each mesh unit in the target region. The security situation analysis method provides a security situation analysis technology with more comprehensive evaluation indexes, a more accurate and reliable analysis result and faster processing.

Description

technical field [0001] The invention relates to the field of security technology, in particular to a security situation analysis method and device. Background technique [0002] With the rapid development of economy, politics and culture and the further improvement of the degree of internationalization, the security situation faced by our country is more complicated and severe than in the past. Conservation brings with it enormous pressures and challenges. Before and after violent terrorist incidents, public security agencies urgently need to combine various technologies to assess the situation and development of violent terrorist incidents and take emergency measures. [0003] Remote sensing satellites have the characteristics of high definition, high quality, and high revisit cycle, and have been widely used in many fields. Public security organs face many difficulties in maintaining stability and dealing with emergencies, and remote sensing technology plays an irreplace...
