Embodiment Construction

[0034] The present invention provides a multi-disaster secondary derivative coupling simulation demonstration device and method for urban public security. The present invention will be further described in conjunction with the accompanying drawings and specific implementation methods below.

[0035] like figure 1 As shown, the demonstration device includes three parts: a dynamic sand table 1, a projection device and a control system. A city model 2 is set on the dynamic sand table 1, and a movable elevator 3 and a vibration meter 4 are set inside the dynamic sand table 1; a vibration tester, a fan, an anemometer, and a camera are set on the dynamic sand table 1. The projection equipment is divided into three parts: a dynamic sand table projector 5, a three-dimensional animation projector 6 and a horizontal projection screen 7. A plurality of dynamic sand table projectors 5 are located above the dynamic sand table 1 and projected onto the dynamic sand table 1 from top to bottom...

Abstract

A demonstration device and a demonstration method for urban public security multi-disaster secondary derivation coupling simulation belong to the technical field of public security simulation. The demonstration device comprises a dynamic sand table, a projection device and a control system. An urban model is arranged on the dynamic sand table, a movable lift and a vibration instrument are arranged at positions inside the dynamic sand table. A detecting device is arranged on the dynamic sand table, and the projection device is divided into a dynamic sand table projector, a three-dimensional animation projector and a horizontal projection screen. By means of a method based on three-screen linkage by combining a physical model and a virtual three-dimensional image, demonstration of experiments and value simulation results of happening and developing rules under the conditions of urban multiple emergency events and coupling of the events is achieved. Dynamic demonstration of links of disaster field simulation reappearance, monitoring, information delivering, information access, predicting, pre-warning and decision control and the like are achieved. Visual presentation means are provided for the disaster reappearance, risk evaluation, scene deduction, pre-arranged planning practice, education and training and the like.

Description

technical field [0001] The invention belongs to the technical field of public safety simulation, in particular to a demonstration device and method for urban public safety multi-disaster secondary derivative coupling simulation demonstration. Background technique [0002] The focus of public safety is on the city. Safety is the first element of a modern city, and city safety is generally highly valued by the government, society and the public. Public safety technology is an effective support for effectively responding to emergencies and improving emergency response capabilities, and urban public safety research facilities are a necessary means for developing urban public safety technology. The lack of comprehensive experimental facilities for urban public safety research in our country is very unfavorable for the comprehensive, overall and common scientific issues of urban public safety and emergency technology research. At present, urban public safety emergencies have a w...
