Problems solved by technology

Its disadvantages are: the indicating unit is fixed on the seat or the ground, it is likely to be difficult to observe due to the crowding of people during evacuation, and since the indicating unit is determined according to the initial random distribution of personnel, the indicating mark needs to be able to indicate multiple directions functions to adapt to different evacuation scenarios, which put forward higher requirements for the design, wiring, maintenance, etc. of the entire building, and the cost is high

Embodiment 1

[0041] see figure 2 , Embodiment 1 of the present invention provides a method for navigating personnel in a building floor, including the following steps:

[0042] Step S100: First, the server directly or indirectly collects the location information of personnel and evacuation exits in the building; during specific implementation, the server can directly obtain the above-mentioned personnel location information and evacuation exit location information collected through the server; of course, the server can Obtain personnel location information and evacuation exit location information indirectly through acquisition equipment such as positioning devices;

[0043] Step S200: The server determines an initial population mean dividing line A according to the number distribution of all people in the building, so that the number of people on both sides of the mean number dividing line A is equal or the difference between the number of people on both sides is less than the preset valu...

Embodiment 2

[0056] see image 3 , Embodiment 2 of the present invention provides a method for navigating personnel on a building floor. The main processing method of the navigation method is the same as that of the method for navigating personnel on a building floor in the first embodiment above. The main operations include the steps S100-step S800, about the above-mentioned steps S100-step S800 can also refer to image 3 Not only that, the method for personnel navigation in the building floor involved in the second embodiment of the present invention also involves technical solutions such as dynamic acquisition and monitoring, rational division of the initial factor balance line C, etc.;

[0057]When step S100 is executed, the method for navigating people on a building floor according to Embodiment 2 of the present invention needs to collect the location information of people in the building in real time; and needs to update and collect the location information of all people every preset...

Embodiment 3

[0064] The third embodiment of the present invention provides a method for navigating personnel in a multi-storey building, which can be applied to a multi-storey building. When implementing route planning for two left and right evacuation exits in a multi-storey building, it is necessary to process the comprehensive evacuation route according to the principle of the shortest route combined with the personnel navigation method in the first embodiment of the building.

[0065] For an example, see Figure 5 ( Figure 5 It is a floor plan of a building with a composite three-dimensional structure of 5 floors), for example, the building structure is divided into 5 floors, each floor has the same structure, each floor has 8 rooms, and there is a staircase (evacuation exit) on the left and right sides, and the exit is located at a the left and right sides of the layer. The personnel allocation method in this case is as follows: First, divide according to the principle of the short...

Abstract

The invention discloses a personnel navigation method in a building floor, a personnel navigation method in a multi-storey building and a navigation system. The personnel navigation method comprehensively considers personnel position information and evacuation exit information, iterative solution is carried out by taking the condition of the shortest overall escape time as a solution target, and finally, an optimal evacuation path is obtained. According to the navigation method, the evacuation path can be planned more scientifically, and once an emergency occurs, the optimal evacuation path can be determined quickly according to the current personnel distribution condition; and meanwhile, each individual person can independently observe the own evacuation path, so that the escape efficiency is higher.

Description

technical field [0001] The invention relates to navigation technology, in particular to a navigation method for personnel on a building floor, a navigation method and a system for personnel in a multi-storey building in case of disasters such as fire. Background technique [0002] In recent years, with the rapid development of social economy, various large-scale public activities that gather a large number of people are increasing. In some crowded public buildings, due to unreasonable architectural design and inadequate emergency management , when various emergencies occur and personnel need to evacuate urgently, it is easy to cause crowding and obstruction of the evacuated crowd, and even serious stampede accidents occur. [0003] After research, it is found that more path evacuation methods in the prior art are based on distance and analysis of path node obstacles as the main reference factors to design and plan paths (such as the technical solutions involved in the naviga...
