Description

Technical Field

[0001] The present invention relates to the technical field of intelligent evacuation, and in particular to a method and system for intelligently generating an emergency evacuation plan. Background Art

[0002] With the development of modern chemical industry towards intensification, large-scale and optimization, chemical parks have become a new model for the development of the chemical industry. However, while promoting the rapid development of the local economy, there are also serious safety issues. In recent years, the safety production situation in the chemical industry has been very severe, with various major and extremely serious explosions, fires and leaks occurring frequently. Once an accident occurs in a chemical park, emergency evacuation of personnel will be an important issue.

[0003] The existing emergency evacuation system consists of static evacuation signs installed on the passageway pointing to the safe exit. It cannot respond to changes at the accident site, and cannot dynamically adjust the escape direction signs, which makes it difficult to escape from the scene. In addition, the evacuation sign system has low intelligence. When an accident occurs in a building, the evacuation sign system cannot understand the situation at the accident site in time, and it is likely to mislead people to evacuate in the direction of the serious accident trend. Summary of the invention

[0004] To this end, the embodiments of the present invention provide an emergency evacuation plan intelligent generation method and system, which are used to solve the problem that the evacuation indication system in the prior art has low intelligence and cannot provide the best evacuation route in time.

Figure 2 As shown, an embodiment of the present invention proposes a method for intelligently generating an emergency evacuation plan, the method comprising:

[0087] Step S1: Based on the park plan map, geographic information scene creation and data association are performed to obtain a digital visualization map, wherein the digital visualization map includes a starting point, a concentration point, a control point, a path, and a building, wherein the building and the path around the building and the starting point are mutually associated;

[0090] Step S4: according to the evacuation mode, automatically or manually create or modify the evacuation routes, automatically merge the generated evacuation routes, and automatically supplement the unselected evacuation routes to obtain the optimal evacuation path;

[0091] Step S5: According to the optimal evacuation path, key information of the evacuation plan is automatically generated to obtain an emergency evacuation plan;

[0092] Among them, the starting point is the starting position of the evacuation route for personnel in the park, the concentration point is the end point of the evacuation route for personnel in the park, the control point is the intersection of two or more paths other than the starting point and the concentration point, the path is a line segment connected by two adjacent points among the starting point, the concentration point and the control point, and the coordinates of the path include at least one of the starting point, the concentration point and the control point.

[0093] From the above technical solutions, the present invention provides an intelligent generation method for emergency evacuation plans. By creating geographic information scenes and associating data based on the park plan map, a digital visualization map is obtained; the type, location, severity and impact range of the accident are perceived and marked in real time, and the evacuation plan is initialized with information configuration; the evacuation mode is determined according to the type, severity and impact range of the accident; the evacuation route is automatically or manually created or modified, and the generated evacuation route and the unselected evacuation route are automatically merged to obtain the optimal evacuation path; the key information of the evacuation plan is automatically generated to obtain the emergency evacuation plan. The present invention has the ability to intelligently plan the best evacuation route according to the imagined complex accident scene, and has the ability to manually plan or adjust the evacuation route, so that the intelligent emergency evacuation system has better adaptability (such as balancing the evacuation flow), and has the ability to quickly and intelligently plan the best evacuation route in real time according to the actual accident situation. In addition, the present invention can reduce the difficulty of evacuation design and command at complex accident sites, improve and ensure the feasibility of all evacuation plans, eliminate the possible misoperation caused by human factors when the amount of artificial plans is large, ensure the correctness of the evacuation indication direction, and make intelligent evacuation more secure and safe.

[0094] In this embodiment, step S6 is also included: intelligently managing and querying the emergency evacuation plan, and selecting a suitable evacuation plan according to the actual situation, including automatically matching the evacuation plan with the wind speed and direction and automatically matching the evacuation plan with the region. Therefore, the present invention also has the ability to intelligently manage and query the emergency evacuation plan, and can quickly select the most suitable evacuation plan and issue it for execution.

[0095] In this embodiment, in step S1, based on the park plan map, geographic information scene creation and data association are performed to obtain a method for obtaining a digital visualization map, specifically including:

[0096] Regional data creation: Based on the park floor plan, basic static data is constructed. The basic static data includes the starting point, concentration point, control point, and path; the starting point is the starting position of the evacuation route for personnel in the park, the concentration point is the end point of the evacuation route for personnel in the park, the control point is the intersection of two or more paths other than the starting point and the concentration point, the path is a line segment connecting two adjacent points among the starting point, the concentration point, and the control point, and the coordinates of the path include at least one of the starting point, the concentration point, and the control point.

[0097] Scene image drawing: Based on the starting point, concentration point and control point, a path weighted undirected graph is constructed with the length of the path as the weight.

[0098] Scene data association: Based on the path weighted undirected graph, the building data in the park is constructed, and the building data is associated with the paths and starting points around the building to obtain the associated paths and associated starting points of the building.

[0099] Equipment geo-positioning: Based on the associated path, the evacuation indication equipment is evenly distributed on the path to obtain a digital visualization map; according to the actual location of the meteorological monitoring equipment, it is marked on the digital visualization map, and the location information of the broadcasting equipment and the outdoor display equipment is correlated with at least one of the building data and the starting point associated with the building.

[0100] In this embodiment, in step S2, the type, location, severity and impact range of the accident are sensed and marked in real time, and the evacuation plan is initialized. Specifically, the method for initializing the evacuation plan includes: inputting the name of the evacuation plan, inputting the description text of the evacuation plan, selecting the evacuation mode, selecting the enabling state of the meteorological environment monitoring equipment, broadcasting equipment, and outdoor display equipment, selecting the accident level, and inputting the wind speed to select the wind direction. Finally, the location of the accident is marked on the digital visualization map, a draggable accident point icon is generated, and the accident point icon is associated with the building where the accident occurred.

[0101] The evacuation modes include: global evacuation mode, designated facility evacuation mode, designated radius evacuation mode and wind direction angle evacuation mode.

[0102] In this embodiment, in step S3, based on the basic data information of the digital visualization map, the evacuation mode is determined according to the type, severity and impact range of the accident. The method for determining the evacuation mode is: when the accident affects the entire area, the evacuation mode is determined to be a global evacuation mode; when the accident only affects the building where it is located, the evacuation mode is determined to be a designated facility evacuation mode; when the accident only affects buildings within a certain range, the evacuation mode is determined to be a designated evacuation radius evacuation mode; when the accident type is confirmed to be a toxic gas leak, and the wind direction data collected by the meteorological monitoring equipment exceeds the specified threshold, and the accident has an impact on the building at the downwind outlet, the evacuation mode is determined to be a wind direction angle evacuation mode.

[0103] In this embodiment, in step S4, according to the evacuation mode, evacuation routes are automatically or manually created or modified, and the generated evacuation routes are automatically merged, and the unselected evacuation routes are automatically supplemented to obtain the optimal evacuation path.

[0104] In order to generate the optimal generation route, the present invention adopts the Dijkstra algorithm. The function of the Dijkstra algorithm is: given a vertex in the weighted connected graph, called the starting point, find the shortest distance between the starting point and all other vertices. The idea of ​​the Dijkstra algorithm: adopt the greedy method idea, perform n-1 searches (PS: n is the total number of vertices in the weighted connected graph, excluding the starting point, there are n-1 vertices left), the first search is performed to find the vertex closest to the starting point, and mark it as traversed; the next time the search is performed, find the vertex closest to the starting point from the vertices that have not been traversed, and mark it as traversed; until n-1 searches are completed, the search ends and the final result is returned.

[0105] Combination Figure 3 , Figure 4 To illustrate the process of using Dijkstra's algorithm to find the single-source shortest path starting from point A.

[0106] Specifically, the method for automatically creating evacuation routes:

[0107] Step 1: Read all paths and path weight information in the area;

[0108] Step 2: According to the type, location, severity, impact range and determined evacuation mode of the accident, find the set of all starting points S and the set of concentration points J in the whole area;

[0109] Step 3: Encapsulate the two-dimensional matrix array of the relationship between each evacuation point according to the above two steps;

[0110] Step 4: Obtain the shortest distance from each starting point S(i) to all the concentrated points J(n) according to the Dijkstra algorithm, and then compare the shortest route L from the starting point S(i) to each concentrated point J(n) (each L in the table can be obtained according to the Dijkstra algorithm), as shown in Table 1 below. Encapsulate the minimum value of each row in Table 1 into a set, convert the data in the set into the data required by the user, and return it, as shown in Table 1 below. Figure 5 As shown, Figure 5 The parameter "paths" collection returns the data of the five shortest routes from the starting point to the central point.

[0111] Table 1

[0112] J1 J2 J3 J4 … Jn S1 L(1,1) L(1,2) L(1,3) L(1,4) … L(1,n) S2 L(2,n+1) L(2,n+2) L(2,n+3) L(2,n+4) … L(2,2n) S3 L(3,2n+1) L(3,2n+2) L(3,2n+3) L(3,2n+4) L(3,3n) … … … … … … … Si L(i,n(i-1)+1) L(i,n(i-1)+2) L(i,n(i-1)+3) L(i,n(i-1)+4) … L(i,n*i)

[0113] In order to meet the actual situation and accurately and automatically calculate the optimal evacuation route, the emergency evacuation plan introduces the concept of road (path) weights, that is, when an accident occurs in a region, the roads bound to the region are affected by the different severity of the accident. According to the severity of the accident, the roads bound to the region can be assigned weights, or the roads can be manually assigned weights to restrict the accessibility of the roads, thereby achieving one of the conditions for automatically calculating the optimal evacuation route. The impact weight is as follows Figure 6 shown.

[0114] Combine the following Figure 7 , Figure 8 Explain the impact of weights. Figure 7 Evacuation demonstration: When an accident occurs in the material warehouse, the starting point S1 associated with the PP granulation plant in the designated area is evacuated. If the accident is a minor accident, the impact on the roads around the material warehouse area is negligible, and the optimal evacuation route is to start from the starting point S1, evacuate upwards, and reach the evacuation concentration point J1. The total distance calculated is: 450m, such as Figure 7 Evacuation routes are shown in the figure.

[0115] When the accident is a serious accident, the impact on the roads around the accident site is great or even prohibited (as shown by the lines around the accident point area). The optimal route is automatically calculated to start from the starting point S1, bypass the roads around the accident point and evacuate downward to the evacuation concentration point J1. The total distance calculated is: 671m. If the original route is evacuated according to the weighted calculation, the total distance is: 2613m. Figure 8 The evacuation routes are shown.

[0116] To manually create an evacuation route:

[0117] First, based on the accident point G and the accident type, the starting point S associated with the building J affected by the accident is intelligently identified, and S is used as the starting point for manually creating an evacuation route. The starting point Sn (generally referring to the starting point) associated with the building Jn (generally referring to the unaffected building) not affected by the accident point G is automatically disabled. Assuming that an accident occurs in building J (PP mixing), the accident only affects building J (PP mixing) and the surrounding roads. The starting points for manually creating an evacuation route are intelligently identified as S28, S29, and S30, and only the three starting points S28, S29, and S30 are open for selection, such as Fig. 9 As shown.

[0118] Then manually click each control point, starting point or concentration point. Each time you click, only its adjacent points are displayed for selection to avoid skipping or missing points. A set of points arranged in order is generated as an evacuation route. Fig. 9 For example, manually click the starting point S28, intelligently identify the point C10 adjacent to S28, and open C10 as a clickable control point, and connect C10, such as Fig.10 shown.

[0119] Intelligently identify points C9 and C11 adjacent to C10 (remove the connected adjacent point S28), open C9 and C11 as clickable control points, and connect C9 here, such as Fig.11 shown.

[0120] Intelligently identify points S10 and S29 adjacent to C9 (remove the connected adjacent point C10), open S10 and S29 as clickable control points, and connect S10 here, such as Fig.12 As shown. Intelligently identify points S12 and C21 adjacent to S10 (remove the connected point C9), open S12 and C21 as clickable control points, and connect S12 here, as shown Fig.13 As shown. Intelligently identify points Z2 and S15 adjacent to S12 (remove the connected point S10), open Z2 and S15 as clickable control points, connect Z2 here, and thus form an evacuation route from the starting point S28 to Z2, as shown Fig.14 Finally, multiple evacuation paths are obtained by drawing multiple times. Fig.15 shown.

[0121] The methods for manually or automatically modifying the evacuation route specifically include:

[0122] Manual modification: first delete the current evacuation route, then redraw it, and then save the redrawn evacuation route; automatic modification: modify the specified area, or modify the accident point, or the evacuation radius, and then recalculate the evacuation route; manual modification of the evacuation route and automatic modification of the evacuation route are performed separately.

[0123] Furthermore, the method for automatically merging the generated evacuation routes is as follows:

[0124] When a path Rn is a component of multiple evacuation routes, if the evacuation directions of multiple routes are the same at Rn, then Rn is a unidirectional evacuation path (horizontally to the left, horizontally to the right, vertically upward, vertically downward, and the inclined route is determined after rotation); if multiple routes have two evacuation directions at Rn, then Rn is a bidirectional evacuation path (horizontally bidirectional, vertically bidirectional, and the inclined route is determined after rotation); traverse all evacuation routes, obtain whether the evacuation direction of each path Rn participating in the evacuation is unidirectional or bidirectional, and complete the merging of evacuation routes.

[0125] Furthermore, if Fig.16 As shown, S(n) is the evacuation starting point, C(n) is the evacuation control point, and J(n) is the evacuation assembly point. The method for automatically supplementing the unselected evacuation routes is:

[0126] Step 1: Generate an evacuation route from the starting point S to the concentration point J according to the algorithm for generating the optimal evacuation route.

[0127] Step 2: Find all control points C in the area that are not on the evacuation route, that is, obtain all control points that do not pass through the evacuation route: C1, C5, C8, C9.

[0128] Step 3: If Fig.17 As shown, the control points that did not pass through the evacuation route in the second step are used to generate the evacuation route according to the algorithm; among them, the "first step" generates route a: S2-C6-C2-C3-J1, and the "second step" generates route b: C9-S2-C6-C2-C3-J1. Since "route b" completely contains "route a", the two routes can be merged into one route according to actual conditions.

[0129] Step 4: If Fig.18 As shown in the figure, all evacuation control points are on the evacuation route. Find the routes that have not been generated for evacuation and use two-way evacuation. The routes that have not been generated for evacuation are: route (C3, C4) and route (S2, S3).

[0130] In this embodiment, in step S5, based on the optimal evacuation path, the key information of the evacuation plan is automatically generated to obtain the emergency evacuation plan. The method for automatically generating the key information of the evacuation plan is: automatically extracting the key information in the evacuation plan configuration and generation process, integrating the relevant parameters and naming mapping tables in the data dictionary, and automatically generating the key text description information of the evacuation plan. The key text description information of the evacuation plan includes the type of accident, the building to be evacuated, the evacuation route, and the length of the evacuation route.

[0131] In this embodiment, step S6: intelligently manage and query the emergency evacuation plan, and select a suitable evacuation plan according to the actual situation, including automatic matching of wind speed and direction evacuation plan and automatic matching of area evacuation plan.

[0132] Specifically, the automatic matching of wind speed and direction to evacuation plan is: when an accident occurs, according to the wind speed and direction data collected by the meteorological sensor, the evacuation plan that meets the wind speed and direction is automatically matched for the user to choose. When the wind direction does not work, all evacuation plans are loaded, such as Fig.19 When the wind direction takes effect, the current wind is southeast, and the platform automatically matches the southeast wind evacuation plan, such as Fig. 20 shown.

[0133] The automatic regional evacuation plan is: when an accident occurs, the location of the area where the accident occurred is uploaded according to the location function of the accident point, and the evacuation plan that meets the requirements of the area is automatically matched. Fig.21As shown, when an accident occurs in the ethylbenzene area, the platform can know that an accident has occurred in the area based on the positioning, and automatically matches the evacuation plan that suits the area for evacuation.

[0134] Furthermore, the method of the present invention can also be applied to large multi-story complex buildings. The above method is a method for generating an evacuation plan for a single floor. On the basis of the existing plan, the stairs between floors are taken into account, so that the automatic generation of evacuation plans for multi-story buildings can be realized. Therefore, the intelligent automatic, manual creation or modification of evacuation route algorithms for the intelligent emergency evacuation system of large multi-story complex buildings can be realized by making certain modifications to the algorithm of this patent, and is also within the scope of protection of this patent.

[0135] In addition, the present invention also has the ability to handle multiple accident points at the same time. In the case of multiple accident points at the same time, only the weights of the local paths need to be modified to generate evacuation plans for different accident points.
