The method can be carried out by means of the determination of the evacuation duration, which means can be implemented in software and/or hardware.
Before the technical solution of the embodiment of the present invention is introduced, an application scenario of the embodiment is introduced adaptively. Of course, the following application scenarios are only described as alternative embodiments, and the technical solution of the embodiment of the present invention may also be applied to other application scenarios, and the application scenarios of the technical solution are not limited in this embodiment. The specific application scenarios include:
with the continuous development of shipbuilding technology, the design and construction of ships show the trend of large-scale, complicated and intelligent development, the ship load capacity and passenger capacity are continuously increased, and once disasters such as overturning, fire and the like occur, more huge life and property losses are often caused. Therefore, how to realize orderly and rapid evacuation of a large number of people in a complicated and narrow hull space becomes a key problem in ship design.
In order to solve the above technical problem, in the technical solution of this embodiment, the evacuation duration of each evacuation route is quickly calculated by using the path data of the path segment of each evacuation route based on an Excel table and a preset interpolation formula in the table, and the specific technical solution includes: acquiring path data of each path section in any evacuation route, and respectively determining target traffic flow of each path section based on the path data of each path section and the position information of each path section; the congestion condition of the current path section can be seen through the target traffic flow; further, determining the people duration and the people moving duration of the evacuation route based on the short target traffic flow of each route and the route data of each route section in any evacuation route, and determining the evacuation duration of the evacuation route based on the people flow duration and the people moving duration; the evacuation duration of each evacuation route is flexibly determined, so that personnel on the ship can be quickly evacuated to a safe position after danger occurs in each random area during ship abandoning and evacuation, and the safety guarantee of the ship is improved.
As shown in fig. 1, the technical solution of the embodiment of the present invention specifically includes the following steps:
and S110, acquiring path data of each path section in any evacuation route, and respectively determining the target traffic flow of each path section based on the path data of each path section and the position information of each path section.
In the embodiment of the invention, the evacuation route is a route from a local point to a designated rendezvous point for crews and passengers on the ship when the ship is in danger, and the evacuation route can include, but is not limited to, an evacuation route obtained by randomly combining various route sections; the path segments may be respective areas on the vessel, for example, the path segments may be divided into path segments such as corridors, doors, and stairways based on type, and the number of the path segments included in the evacuation route is at least one end, i.e., one evacuation route may include only one path segment or may include a plurality of path segments. The path data for a path segment includes net width data, length data, and the number of people within the path segment. Where the net width of a path segment may be the width data in that path segment, such as the actual channel width from the handrails of corridors and stairways and the doors in the fully open position. The length of a path segment is the actual length from the beginning end to the end of the path segment. The target traffic flow may be the number of people passing through the path segment per unit time.
Specifically, the method for respectively determining the target traffic flow of each path segment based on the path data of each path segment and the position information of each path segment includes: determining the personnel density of the path section based on the net width data, the length data and the personnel number of the path section, and determining the target flow ratio of the path section based on the density data; further, a target traffic flow for the path segment is determined based on the target traffic ratio and the net width data for the path segment.
Wherein the person density is the area occupied by a single person within the path. The person density is determined by the area of the path segment determined by the net width data and the length data of the path segment and the number of persons within the range of the path segment. Specifically, the net width data and the length data of the path section are multiplied to obtain the area of the path section; and dividing the number of the persons in the range of the path section by the area of the path section to obtain the person density of the path section.
In some embodiments, the path association list is previously established in accordance with the positional relationship of the respective path segments of the respective evacuation routes. Wherein any path in the path association list comprises at least one adjacent path. When the path section is a starting path section or an ending path section in the evacuation route, only one end adjacent to the path section is provided with an adjacent path section; when the path section is an intermediate path section, both ends adjacent to the path section are provided with adjacent path sections.
Optionally, when the route segment is a starting route segment in the evacuation route, the method for determining the target flow ratio of the route segment based on the person density of the route segment includes: determining a target flow ratio of the path section based on the personnel density and a preset interpolation formula of the flow ratio; when the path segment is an intermediate path segment or an end path segment in the evacuation route, the method of determining the target flow ratio of the path segment based on the density of people in the path segment further includes: determining an initial flow ratio of a path section based on a personnel density and flow ratio preset interpolation formula; if the initial flow ratio is smaller than a preset path flow ratio threshold value, taking the initial flow ratio as a target flow ratio of the path section; or, if the initial flow rate ratio is greater than the preset path flow rate ratio threshold, the preset path flow rate ratio threshold is used as the target flow rate ratio of the path segment. Wherein the target flow ratio may be the flow within a unit of net width of the path segment.
Specifically, the target flow rate ratio can be determined by comparing a preset path flow rate threshold value after an interpolation formula is preset by the personnel density and the flow rate ratio; optionally, the initial flow rate ratio of the path segment may be determined by a preset interpolation formula of the personnel density and the flow rate ratio. When the numerical values of the personnel density are different, the adopted interpolation formula is also different. Illustratively, as shown in the following table, when the personnel density of any path segment is in the range of 1.9< D ≦ 3.2, the preset flow ratio interpolation formula for determining the initial flow ratio of the path segment is: 441/325-D × 47/130.
Table 1: flow ratio preset interpolation formula table
Personnel density D (p/m)2) Flow ratio preset interpolation formula
0<D≤0.5 D×1.3
0.5<D≤1.9 D×13/28+117/280
1.9<D≤3.2 2.25-D×0.5
3.2<D<3.5 4.17-D×1.1
D≥3.5 0.32
And comparing the determined initial flow ratio of the path section under each personnel density with a preset path flow ratio threshold value, and determining a comparison result. If the initial flow ratio is smaller than a preset path flow ratio threshold value, taking the initial flow ratio as a target flow ratio of the path section; and if the initial flow ratio is larger than the preset path flow ratio threshold, taking the preset path flow ratio threshold as a target flow ratio of the path segment, and after the preset path flow ratio threshold is taken as the target flow ratio of the path segment, forming an evacuation queue at the path segment, and orderly queuing and evacuating the personnel in the queue. The operation of determining the target flow ratio has the beneficial effects that: the speed of the flow of the person in the section of the path can be controlled so as to avoid dangerous events such as trampling.
Specifically, the method for determining the target traffic flow of the path segment based on the target traffic ratio and the net width data of the path segment may include: and multiplying the target traffic ratio of the path section by the net width data of the path section to determine the target traffic of the path section.
Specifically, a method for determining a target traffic flow of any route segment in any evacuation route is described as an example: at least one adjacent path segment of the path segment is determined based on the location of the path segment. Optionally, when the path segment is a starting path segment, the determination method described in the above embodiment is based on the path data to determine the target traffic flow. When the path segment is an intermediate segment or an end segment, the target traffic flow of the path segment can be determined according to the number of adjacent path segments. For example, when the path segment is a convergence of a plurality of path segments, the target traffic flow of the path segment is a sum of adjacent target traffic flows of adjacent path segments. And when the path section is the turning point of other types of path sections, determining the target traffic flow of the current path section based on the preset conversion relation of the target traffic flow among different types and the adjacent target traffic flow. Of course, the method for determining the target traffic flow is only an optional embodiment, and the target traffic flow of the path segment may also be specifically determined according to the actual situation, and this embodiment is not limited again.

In an embodiment of the invention, the duration of the stream of people may be interpreted as the duration of time from the first person to the last person passing through the path segment among all people within any path segment. The duration of the pedestrian flow of any path segment can be determined by the number of people in the range of the path segment and the target passing number of the path segment. The person movement duration is the duration of time that any person within any path segment passes through the range of path segment lengths. The moving time of the personnel in any path section can be determined by the length data of the path section and the moving speed of the personnel in the path; the moving speed of the personnel can be determined by a personnel flow ratio of the path section and a preset interpolation formula of the moving speed.
Specifically, the method for determining the duration of the stream of people of any path segment may include: dividing the number of people by the target passing number can obtain the duration of the pedestrian flow of the path section. According to the method, the people flow duration of other path sections of the evacuation route where the path section is located is calculated, the people flow duration is compared, and the people flow duration with the largest value in the comparison result is used as the people flow duration of the evacuation route.
Specifically, the method for determining the movement duration of the person in any path segment may include: and obtaining the personnel moving speed of the path section based on a preset difference formula of the personnel flow ratio and the moving speed of the path section. As shown in table 2, the preset moving speed difference formula is different according to the type of the path segment and the personnel flow rate of the path segment:
table 2: formula table for preset difference value of moving speed
Figure BDA0003090779320000091
Of course, in some embodiments, if the path segment is the starting path segment, the determination may also be based on the preset difference formula between the personnel density of the path segment and the initial moving speed, and as shown in table 3 for example, the preset difference formula for the moving speed is different according to the different personnel density of the path segment:
table 3: initial moving speed preset difference value formula table
Figure BDA0003090779320000092
And determining the ratio of the length data of the path section to the personnel moving speed obtained based on the technical scheme as the personnel moving time length of the path section. And determining the personnel moving time length of each path section included in the evacuation route where the path section is located based on the method. The person movement time lengths of the respective path sections in any one of the evacuation routes are summed up and calculated. And determining the personnel moving time length of the evacuation route according to the summed personnel moving time length.
Specifically, the method for determining the evacuation duration of any evacuation route based on the flow duration and the movement duration of people of the evacuation route includes: and adding the duration of the people stream and the movement duration of the people, and multiplying the added result by a preset coefficient to obtain the evacuation duration of the evacuation route. Specifically, the predetermined coefficient includes a sum of a positive correction coefficient and a negative correction coefficient.
Of course, the method for determining the evacuation time length of the evacuation route based on the path data of each path segment in the evacuation route and the target traffic flow of each path segment is only an optional embodiment, and the evacuation time length may also be determined according to other methods, which is not limited by the embodiment.
The technical scheme of the embodiment of the invention specifically comprises the following steps: acquiring path data of each path section in any evacuation route, and respectively determining target traffic flow of each path section based on the path data of each path section and the position information of each path section; the congestion condition of the current path section can be seen through the target traffic flow; further, determining the people duration and the people moving duration of the evacuation route based on the short target traffic flow of each route and the route data of each route section in any evacuation route, and determining the evacuation duration of the evacuation route based on the people flow duration and the people moving duration; the evacuation duration of each evacuation route can be flexibly determined.
