A case-based emergency situation deduction method and system

Abstract

The invention discloses a method and a system for deducing a sudden event situation based on a case. The method comprises the steps of generating a case script of the case, abstracting the case script, extracting a case event link and storing the case event link in a server database; by a client, obtaining the case event link from the server database, analyzing the case event link, generating a logic relationship and specific information of the event in the case, generating a scalable vector diagram of the event based on the logic relationship and the specific information and adding the scalable vector diagram to a page of a webpage; and adjusting the scalable vector diagram based on the logic relationship, finishing the showing of the sudden event situation by combining with a visualization technology, and finishing deduction of the event automatically by adopting a Bayesian probability statistics principle and by combining with the internal logic probability of the event. According to the method and the system for deducing the sudden event situation based on the case, a visual showing and editing function of the event link is provided, and assistance is offered for non-specialized persons to edit and drill the script.

Description

technical field [0001] The invention relates to the field of situation deduction, in particular to a case-based emergency situation deduction method and system. Background technique [0002] Emergency chains can be used for emergency drills and disaster prevention. Traditional emergency drills are mainly conducted in the form of "desktop deductions". Before the drills, professionals select cases from the drill library according to the purpose and theme of the drill, and arrange the existing content according to the drill time and scale. It is a text or audio-visual image library that stores a large number of drill cases, usually organized in the form of paper or electronic documents. Each drill case in the library is based on objective reality, and is carefully arranged by professionals for teaching purposes. The case database includes floods, earthquakes, dammed lakes, fires, etc., as well as cases composed of the above-mentioned events. During the drill, professionals wil...

Problems solved by technology

[0003] In the traditional emergency rehearsal process, the generation and editing of the emergency event chain often requires more professional knowledge and practical experience, and in the rehearsal process, it is difficult for non-professionals to predict the next event according to the current event development status. The objective evaluation of the development situation of the event at any time, resulting in unclear event development logic and lack of adjustment during the exercise. In the traditional deduction process, the event situation is usually expressed in a passive way, that is, when the host announces It is difficult to provide participants with a sense of being on the scene with this passive expression, so that they cannot clearly understand the current situation of the event, and the user experience is not good. In addition, during the exercise, event information is usually expressed in an independent, discrete, and geographically independent manner, the expression form is relatively simple, and it is rarely closely integrated with spatial information
