Abstract

According to the evacuation guiding system, the evacuation guiding method, the evacuation guiding medium, the evacuation guiding program product and the evacuation guiding terminal based on the local site re-planning, each site is only responsible for bringing personnel to the next safer position, overlong instructions are prevented from being given in a complex environment, and understanding cost and executing cost are reduced. According to the application, the evacuation guiding information is played in a personified and emotion-soothing mode by the virtual digital person, so that the evacuation guiding information is more compliant than a pure acousto-optic alarm, and the panic diffusion can be effectively reduced especially under high-pressure situations (such as smoke, congestion, tension and the like). According to the application, the local re-planning module is used for recalculating the next route at each station during evacuation guiding, dynamically shielding danger and congestion sides and adjusting evacuation paths in real time, so that the robustness and accessibility of the evacuation paths are obviously superior to those of the one-time global planning. According to the application, after the evacuees are confirmed to enter the safety area, the system can automatically terminate the further guiding state of the evacuees, so that redundant tracking is avoided.

Description

Evacuation guidance system, evacuation guidance method, evacuation guidance medium, evacuation guidance program product and evacuation guidance terminal based on local site re-planning Technical Field The application relates to the technical field of public safety management research, in particular to an evacuation guiding system, a method, a medium, a program product and a terminal based on local site re-planning. Background Currently, in complex spaces such as large commercial complexes, subway hubs, underground commercial streets, industrial parks, hospitals, venues, etc., when a fire, smoke diffusion, dangerous goods leakage, security seal or other sudden public safety events occur, it is necessary to guide a large number of present personnel to rapidly and orderly evacuate from the current location to a safety area in a very short time. The existing emergency facilities mainly use fixed identification and unified broadcasting, lack response capability to real-time situations such as smog, sealing control, channel congestion and the like, and also lack gradual guiding and individual presentation for people at different positions, and part of systems try to give a disposable escape route based on a global map, but are easy to lose efficacy in a dynamic change dangerous environment, and the people are difficult to execute a lengthy global route under high-pressure and low-visibility conditions. The prior art has the following defects: (1) The fixed evacuation markers are not dynamically adjustable. The existing emergency evacuation signs, ground posts, lamp box arrows and the like are fixedly installed, and the indicated 'safety exit direction' is usually a preset static path. The fixed indication may even direct the crowd to the dangerous area once a fire, smoke, containment, slump, etc. is present near the path. (2) Centralized broadcasting lacks personalized guidance. In-field broadcasts are usually uniformly shouting ("please get to nearest exit to safety), but in complex environments of multi-story three-dimensional structures, annular hallways, regional atrium," nearest exit to safety "are not the same for individuals in different locations, and the broadcast cannot be directed to gradual field-level landings. (3) Traditional emergency evacuation maps rely on global path planning. Existing partial intelligent evacuation systems attempt to push a complete escape route to a user based on a path plan for a global scenario. However, in the actual evacuation process, the environmental states such as fire, blockage and the like are also dynamically changed when people move, the globally optimal path is easy to lose efficacy, and the user is easy to get lost in a complex scene, so that the globally optimal path with one breath cannot be executed. (4) There is a lack of station-by-station, in-situ guidance. At present, evacuation guidance often has no 'relay guidance point' (i.e. after going to the next security node, it tells you which one goes next), but instead directly assumes that personnel can 'find the exit' by themselves. This is difficult to achieve for strangers, high density traffic, low visibility environments. Therefore, the core defects of the existing scheme include that the fixed indication cannot avoid burst blocking or fire spreading, the unified broadcasting cannot give consideration to individual position difference, the global path is rapidly outdated in situation evolution, and the scene lacks relay type guidance of 'walking to the next safety node and then to the next step', so that the crowd is easy to lose or jam in the complex structure. Disclosure of Invention In view of the above drawbacks of the prior art, the present invention provides an evacuation guidance system, method, medium, program product and terminal based on local site re-planning, for solving the problems in the prior art that a fixed evacuation identifier is not dynamically adjustable, centralized broadcasting lacks individual guidance, a traditional emergency evacuation map relies on global path planning, and a site-by-site type approach guidance is lacking. To achieve the above and other related objects, a first aspect of the present application provides an evacuation guidance system based on local site re-planning, which includes an environmental status collection module configured to collect environmental status information of a target site in real time, a site topology management module configured to construct a site topology map of the target site according to interactive terminals deployed at each site in the target site in a decentralized manner, update the site topology map based on the environmental status information collected in real time to obtain updated site topology status information, a local re-planning module configured to calculate and obtain an optimal evacuation sub-path from a current site to a next site according to the environmental status information collected in real time, the updated sit
