Emergency commanding and dispatching method and system based on GIS and Beidou positioning

Abstract

The invention discloses an emergency commanding and dispatching method and system based on GIS and Beidou positioning, and the method specifically comprises the following steps: S1, loading basic data and carrying out symbolization display, S2, carrying out the superposition display of road network big data and meteorological data layers, S3, carrying out the positioning to obtain the coordinates of an accident point, and carrying out the plotting on a map, S4, obtaining the real-time condition of a site, and displaying the condition on a GIS large screen of an emergency command center; S5, planning material allocation and transportation route, and S6, mastering of emergency material transportation positions. The invention relates to the technical field of emergency commanding and dispatching. According to the emergency commanding and dispatching method and system based on GIS and Beidou positioning, information acquisition of an accident site is no longer single text description, and real-time audio and video data are additionally provided, so that workers in an emergency commanding center can more comprehensively and visually know the real situation of the site, the emergency commanding and dispatching workers can make an optimal emergency scheme, and the emergency progress can be continuously followed in real time subsequently.

Description

technical field [0001] The invention relates to the technical field of emergency command and dispatch, in particular to an emergency command and dispatch method and system based on GIS and Beidou positioning. Background technique [0002] Natural disasters and safety production incidents occur frequently in our country. In order to protect the safety of people's lives and property, the emergency command system is particularly important. The emergency command system refers to the necessary response mechanism system established by the government and other public institutions in the process of pre-emergency prevention, incident response, mid-event disposal, and aftermath management. Take a series of necessary measures to protect the safety of public life and property. [0003] With the rapid development of geographic information system (Geographic Information System, GIS) technology and space technology, the application of geographic information system has developed into vario...

AI Technical Summary

Problems solved by technology

[0005] 1) The information collection at the accident scene is relatively fragmented, more of a textual description type, lacking audio and video information, making the on-site information obtained by the decision-makers of the emergency command and dispatch center relatively fragmented, and it is impossible to obtain the real situation of the scene in real time, and the information display method is also poor. not intuitive enough

It is not conducive to emergency command and dispatch personnel to make the optimal emergency plan, and the follow-up emergency progress cannot be followed up in real time

[0006] 2) The disposal plan mainly relies on the manual decision-making of emergency command and dispatch personnel, and the rationality of the decision-making basis needs to be verified. The effect of command and dispatch heavily depends on the emergency experience and business capabilities of the command personnel

The rationality of the plan is greatly affected by the personal emergency response capability, and there is even a situation of blind decision-making

[0007] 3) In the process of emergency command and dispatch, all kinds of information are transmitted. The upload and release of emergency tasks mainly rely on telephone and walkie-talkie for point-to-point communication. However, the information contained in the emergency process is complex and changeable. Feedback mainly relies on scheduling telephones and walkie-talkies, which cannot record and analyze process information. The intensity of information exchange is high, and information congestion, omissions, conflicts and errors are prone to occur, resulting in unreasonable and untimely decision-making.

Moreover, the development of various tasks is relatively independent, and there is a lack of effective linkage between operations between different departments, making it difficult to achieve the ideal emergency response

[0008] 5) Internet map data has a certain timeliness. The occurrence of emergency accidents may change the status of the accident point. The current map data may not meet the needs of emergency rescue and cannot provide effective support for emergency command and dispatch.

[0009] For the above problems, no effective solution has been proposed
