Method and system for evaluating dam-break risk of dammed lake based on negotiable and cooperative work flow

Abstract

The invention discloses a method and system for evaluating the dam-break risk of a dammed lake based on a negotiable and cooperative work flow, which are used for the negotiable and cooperative evaluation of the dam-break simulation and influence analysis of the dammed lake. The system is characterized in that a distributed frame based on a four-layer system is adopted. The system consists of three parts: a moving Agent, an AgentHost and a cooperative Agent. In the invention, the centralized decision and treatment of disaster negotiation information are accomplished by providing cooperative virtual work environment of multiple point in different places, command and decision makers and related personnel at all levels in different regions can cooperatively communicate to share and exchange disaster information and take part in discussion about the dam-break simulation and the influence analysis of the dammed lake together, and the cooperative analysis and the evaluation of the dam-break risk of the dammed lake are achieved. The invention has the advantages of simple method and high execution efficiency, is suitable for multiple users distributed in different places to carry out negotiable and cooperative evaluation, and can effectively improve the work efficiency of the dam-break risk evaluation of the dammed lake.

Description

technical field [0001] The invention belongs to the research fields of geographic collaboration technology, geographic information system, geoscience visualization and virtual geographic environment. Background technique [0002] Due to the complexity of the barrier lake problem, many uncertain factors are involved, and the collapse event has the characteristics of sudden occurrence, rapid expansion, decentralized processing part, and urgency of response requirements. Existing evaluation methods have some drawbacks: [0003] 1) There is a lack of a clear and unified barrier lake outburst risk assessment process, and it is difficult to meet the accuracy and depth required for barrier lake outburst risk assessment in complex situations. Moreover, most of the existing work is done manually, and the degree of informatization is not high, and the assessment efficiency is low. Low, it may lead to errors in severe cases.

AI Technical Summary

Problems solved by technology

[0003] 1) There is a lack of a clear and unified barrier lake outburst risk assessment process, and it is difficult to meet the accuracy and depth required for barrier lake outburst risk assessment in complex situations. Moreover, most of the existing work is done manually, and the degree of informatization is not high, and the assessment efficiency is low. Low, it may lead to errors in severe cases

[0004] 2) Lack of shared collaboration, it is difficult to effectively support multi-user collaboration

Collapse risk assessment requires multi-person, multi-field, multi-department collaboration and knowledge sharing to effectively solve problems. However, the existing decentralized combat mode is difficult to ensure effective knowledge sharing and collaboration to quickly solve complex geographic problems

[0005] 3) The degree of visualization is poor, resulting in low cognitive efficiency, and the time-consuming spatial analysis of complex relationships makes it difficult to quickly support cognition and data mining, and affects the accuracy of results

[0006] 4) The spatio-temporal analysis function is weak, and it is difficult to reflect the dynamic change process

Existing spatial analysis functions only include traditional functions such as roaming, distance measurement, area measurement, volume measurement, fixed-point query or simple GIS thematic map overlay, but the spatiotemporal analysis of the flood evolution process and its changing trend is relatively weak

However, the existing methods of simulation and prediction analysis of the geological process of barrier lake outburst are lacking, and most of them focus on the statistical analysis of historical data and empirical judgment, or use a single method for risk analysis, and there are few studies on the combination of quantitative and qualitative risk assessment.
