Description

Technical Field

[0001] This invention relates to the field of evacuation lighting technology, specifically to an emergency lighting method for evacuation indication. Background Technology

[0002] In modern cities, the increasing number of high-rise buildings and large public spaces has led to a rise in population density, making safe evacuation in emergency situations a crucial issue.

[0003] Traditional emergency lighting systems have many shortcomings in evacuation guidance. For example, these systems typically use fixed indicator lights that only point to safety exits and cannot be dynamically adjusted according to real-time personnel locations and evacuation progress. When some escape routes become congested, fixed indicator lights cannot guide people to choose alternative, more unobstructed routes. This not only reduces evacuation efficiency but may also lead to congestion and stampedes.

[0004] Furthermore, traditional emergency lighting systems cannot address the issue of crowds converging at specific routes or intersections, thus failing to prevent excessively high population density in localized areas and increasing risks during evacuation. More importantly, existing systems typically lack consideration for changes in population density and cannot dynamically adjust evacuation strategies based on actual conditions, resulting in suboptimal evacuation outcomes.

[0005] Therefore, an emergency lighting system capable of dynamically adjusting based on personnel location, density, and evacuation status has become a pressing technical challenge. To overcome these limitations, we urgently need a system that can intelligently optimize evacuation routes and dynamically adjust guidance strategies to guide personnel evacuation more efficiently and safely, thereby minimizing safety risks in emergency situations. Summary of the Invention

[0006] The present invention provides an emergency lighting method for evacuation indication, which helps to solve the problems mentioned in the background art above.

[0007] This invention provides the following technical solution: an emergency lighting method for evacuation indication, comprising:

[0008] Obtain all safety exits and personnel gathering points within the target floor;

[0009] The target floor refers to the floor where evacuation instructions need to be given;

[0010] Obtain the shortest escape route for each gathering point;

[0011] The escape routes for each gathering point are entered into the route set and sorted from largest to smallest number of people in each gathering point;

[0012] The escape route starts at the gathering point and ends at the safety exit;

[0013] The target floor contains multiple corridors, and each corridor has multiple safety indicator lights on both sides of the wall;

[0014] The safety indicator lights on each wall consist of multiple safety indicator lights pointing horizontally to the left and horizontally to the right;

[0015] The escape route contains multiple turning points and forks in the road;

[0016] A turning point is a point in the escape route where the direction changes each time.

[0017] The route forks are the intersections of multiple corridors on the target floor;

[0019] When an alarm is triggered, the corresponding safety indicator lights along the escape route will be activated;

[0020] Set a population density threshold to measure the size of the population;

[0021] Once the safety indicator lights for each escape route are activated, each escape route in the route set is divided into multiple route segments, and data is filtered based on the personnel density and personnel density threshold in each route segment.

[0022] Personnel density is the ratio of corridor space to the number of people in the corridor within a route segment;

[0023] Route segments with personnel density exceeding the personnel density threshold will be added to the diversion route segment set.

[0024] The diversion strategy is executed sequentially for each route segment in the set of diversion route segments;

[0025] If all route segments in the diversion route segment set have been traversed, then determine the personnel density of each route segment in the route set;

[0026] If the population density in all segments of each escape route in the route set is less than the population density threshold, then the route forks of each escape route in the route set are obtained in turn and entered into the fork set.

[0027] Each route fork in the fork set is filtered in turn, and the route forks through which multiple escape routes pass are entered into the fork adjustment set;

[0028] By sequentially executing adjustment strategies on each route junction within the junction adjustment set, and activating corresponding safety indicator lights based on the adjustment strategy results, pedestrian flow can be adjusted.

[0029] Otherwise, a diversion strategy will be implemented on route segments where the population density exceeds the population density threshold.

[0031] Each escape route in the route set is divided into multiple route segments according to the turning points;

[0032] Activate in sequence all safety indicator lights on the walls of each escape route that are aligned with the direction of the route.

[0037] Find the intersection of the first set and the set of branch route segments;

[0038] If the number of route segments in the intersection is equal to 1, then the route segments in the intersection will be taken as the target route segments;

[0039] Along the first route, select the route junction closest to the target route segment as the first junction;

[0040] Starting from the first fork in the road, obtain all escape routes other than the first route, and select the shortest escape route as the branching route, and enter the branching route into the route set.

[0046] Optionally, the step of sequentially executing the diversion strategy on each route segment in the diversion route segment set includes:

[0047] If the number of route segments in the intersection is greater than 1, then all route junctions between adjacent route segments in the intersection are obtained, and the route junction closest to the monitoring aggregation point is selected as the first junction.

[0048] Starting from the first fork in the road, obtain all escape routes other than the first route, and select the shortest escape route as the branching route, and enter the branching route into the route set.

[0049] The diversion routes are divided into multiple diversion route segments according to the route junctions;

[0050] Select the branching route segment closest to the first fork as the target branching route segment;

[0051] The escape direction in the target diversion route segment is designated as the first direction;

[0052] Obtain all safety indicator lights in the first direction of the target diversion route segment and enter the first set of safety indicators;

[0053] Sort all safety indicator lights in the first safety indicator set according to their distance from the first fork in ascending order and activate them.

[0054] Optionally, the step of sequentially executing the diversion strategy on each route segment in the diversion route segment set includes:

[0055] The escape direction in the target route segment is designated as the second direction;

[0056] Obtain all safety indicator lights in the second direction of the target route segment and input them into the second safety indicator set;

[0057] Sort each safety indicator light in the second safety indicator set according to its distance from the first fork in ascending order, and turn off all safety indicator lights in the second safety indicator set in sequence, while monitoring the personnel density in the target route segment in real time;

[0058] If the population density in the current target route segment is less than the population density threshold or all safety indicator lights in the second set of safety indicators are turned off, the diversion strategy will be stopped.

[0059] Optionally, the step of sequentially filtering each route fork in the fork set and recording the route forks passed through by multiple escape routes into the fork adjustment set includes:

[0060] Select the route forks in the fork set as the target forks in sequence;

[0061] If the number of escape routes passing through the target fork is equal to 1, then a new route fork in the fork set is selected as the new target fork.

[0062] If the number of escape routes passing through the target fork is greater than 1, then the target fork is added to the fork adjustment set, and a new route fork in the fork set is selected as the new target fork, until all route forks in the fork set have been traversed.

[0063] Optionally, the step of sequentially executing adjustment strategies on each route junction within the junction adjustment set and activating corresponding safety indicator lights to adjust pedestrian flow based on the adjustment strategy results includes:

[0064] Select the route intersections from the intersection adjustment set as the adjustment intersections in sequence;

[0066] Each second route is divided into multiple branch route segments according to the route forks;

[0067] Select the route segment of each second route that passes through the adjusted junction and is closest to the adjusted junction, and enter it into the set of route segments of the adjusted junction;

[0068] The route segment with the highest population density in the set of branch route segments is designated as route segment number one.

[0070] Obtain the average interval between people within Route 2;

[0071] Set an interval threshold for determining the average interval between people;

[0072] The average spacing between people is the ratio of the corridor length within Route 2 to the number of people within Route 2.

[0073] If the average interval between people in section 2 is less than the interval threshold, then the corresponding safety indicator light will be adjusted.

[0074] If the average interval between people in Route 2 is greater than or equal to the interval threshold, then any other route segment in the set of branch route segments except Route 1 is selected as the new Route 2, and the average interval between people in Route 2 is compared with the interval threshold.

[0075] If all branch road segments except for the first road segment in the branch road segment set have been traversed, then a new branch road segment in the branch road adjustment set is selected as the new adjustment branch road segment, and the adjustment strategy is executed.

[0076] Optionally, if the average interval between people within Route 2 is less than the interval threshold, the corresponding safety indicator light will be adjusted, including:

[0077] Set the distance threshold for selecting safety indicator lights;

[0078] Obtain the direction of rotation from line segment 1 to line segment 2;

[0079] The direction of rotation refers to the direction of rotation required to move from line segment one to line segment two;

[0080] If the rotation direction is to the left, then obtain all safety indicator lights on the right wall of line segment 2 that are in the same direction as the escape route of line segment 2 and whose distance from the first fork is less than the distance threshold, and enter them into the adjustment instruction set.

[0081] If the rotation direction is to the right, then obtain all safety indicator lights on the left wall of line segment 2 that are in the same direction as the escape route of line segment 2 and whose distance from the first fork is less than the distance threshold, and enter them into the adjustment instruction set.

[0082] Sort all safety indicator lights in the adjustment indicator set in ascending order of their distance from the adjustment junction;

[0083] If all safety indicator lights in the adjustment instruction set are activated, then turn off all safety indicator lights in the adjustment instruction set in sequence, and select a route junction in the junction adjustment set as the new adjustment junction to execute the adjustment strategy, until all route junctions in the junction set have been traversed;

[0084] If none of the safety indicator lights in the adjustment set are activated, then a new route junction in the junction adjustment set is selected as the new adjustment junction, and the adjustment strategy is executed until all route junctions in the junction adjustment set have been traversed.

[0085] The present invention has the following beneficial effects:

[0086] 1. An emergency lighting method for evacuation guidance: This invention sorts people at gathering points from largest to smallest, prioritizing the evacuation of people in areas with larger numbers, avoiding crowd congestion, and improving overall evacuation efficiency. When an alarm is triggered, the route is divided into multiple sections according to the turning points of the escape route, and safety indicator lights in the corresponding directions are lit, achieving rapid guidance for the initial evacuation.

[0087] 2. This emergency lighting method for evacuation guidance monitors the population density of each escape route segment in real time. When a segment of the escape route has excessively high population density, the system activates a diversion strategy. The system identifies the segments requiring diversion based on population density, avoiding blind diversion and improving accuracy. The diversion strategy first identifies congested segments. If an escape route contains only one congested segment, the nearest junction to that segment is selected as the first junction. If an escape route contains multiple congested segments, the nearest junction to the population gathering point among adjacent congested segments is selected as the first junction. A new escape route is then found from the first junction as the diversion route. Finally, safety indicator lights in the corresponding directions on the diversion route are illuminated to guide people from the congested route to the new route. Starting from the first junction, routes other than the congested ones are selected. Using the shortest escape route outside of the main congestion area as the diversion route ensures its effectiveness and efficiency. Selecting the intersection closest to the congested section as the diversion point reduces the distance people need to detour, improving diversion efficiency. Especially in cases with multiple congested sections, selecting the intersection closest to the gathering point among adjacent congested sections allows for earlier diversion, preventing further congestion. This diversion strategy considers both single and multiple congested sections, increasing its adaptability and better reflecting actual conditions. Dividing the diversion route into multiple segments and activating the corresponding safety indicator lights on the segment closest to the diversion point achieves segmented diversion guidance, preventing congestion at diversion intersections. Gradually illuminating the safety indicator lights on the diversion routes guides people to move slowly and orderly, avoiding confusion and crowding caused by simultaneously activating or deactivating safety indicator lights.

[0088] 3. This emergency lighting method for evacuation guidance selects route intersections from the intersection set that are traversed by multiple escape routes and enters them into the intersection adjustment set for subsequent adjustment strategies of pedestrian flow; by screening, route intersections that do not need adjustment are excluded, reducing the amount of calculation in subsequent processing and improving the overall operating efficiency.

[0089] 4. This emergency lighting method for evacuation guidance processes each route fork in the fork adjustment set sequentially. First, it obtains all escape routes passing through that fork. Then, for each route, it identifies the last route segment before entering the fork. It compares the personnel density of these route segments, designating the segment with the highest personnel density as Route Segment 1, and the remaining segments as Route Segments 2. It calculates the average personnel spacing for Route Segments 2. If the average personnel spacing for Route Segments 2 is less than a threshold, then Route Segment 2 requires lighting adjustment. By iterating through each Route Segment 2, the route segments requiring adjustment can be identified, ultimately achieving a reasonable adjustment. If the average interval between people on Route 2 is greater than or equal to the set threshold, no adjustment is needed, and the process moves to the next intersection for processing. By designating the route segment with the most people as Route 1, priority is given to ensuring the smooth flow of the main evacuation route. Route 2 is then iterated through, and the safety indicator lights on the congested route segments are gradually adjusted to avoid causing new congestion with a one-time adjustment. By calculating the average interval between people, rather than simply the number of people, the degree of congestion on the route segment can be reflected more accurately, making the adjustment strategy more refined.

[0090] 5. This emergency lighting method for evacuation guidance determines the direction of rotation from route segment one to route segment two. Then, based on the rotation direction, safety indicator lights are selected on the wall corresponding to route segment two, within a certain range of the fork in the road, and aligned with the escape direction of route segment two. These lights are added to an adjustment indicator set. Next, the safety indicator lights in the adjustment indicator set are activated sequentially according to their distance from the fork. If all lights in the adjustment indicator set are activated, they are turned off sequentially, and the process moves to the next fork for adjustment. If not all lights in the adjustment indicator set are activated, they remain off, and the process moves to the next fork for adjustment. By selecting safety indicator lights within a certain range of the fork for adjustment, it ensures that personnel can observe the safety indicator lights at the route fork immediately, avoiding excessive concentration of personnel at the fork and reducing the risk of congestion. By sorting the safety indicator lights in the adjustment indicator set according to their distance from the fork and activating them sequentially, it gradually guides personnel to turn, avoiding sudden changes that could cause confusion.

[0093] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0094] Example 1, see Figures 1 to 2 An emergency lighting method for evacuation indication, comprising:

[0095] Obtain all safety exits and personnel gathering points within the target floor;

[0096] The target floor refers to the floor where evacuation instructions need to be given;

[0097] Obtain the shortest escape route for each gathering point;

[0098] The escape routes for each gathering point are entered into the route set and sorted from largest to smallest number of people in each gathering point;

[0099] The escape route starts at the gathering point and ends at the safety exit;

[0100] The target floor contains multiple corridors, and each corridor has multiple safety indicator lights on both sides of the wall;

[0101] The safety indicator lights on each wall consist of multiple safety indicator lights pointing horizontally to the left and horizontally to the right;

[0102] The escape route contains multiple turning points and forks in the road;

[0103] A turning point is a point in the escape route where the direction changes each time.

[0104] The route forks are the intersections of multiple corridors on the target floor;

[0105] Set a threshold for determining the size of the number of people at a gathering point;

[0106] When an alarm is triggered, the corresponding safety indicator lights along the escape route will be activated;

[0107] Based on the number of people gathered at the gathering points, people in the areas with the largest number of people are prioritized for evacuation to avoid crowd congestion and improve the overall evacuation efficiency. When an alarm is triggered, the escape route is divided into multiple sections according to the turning points, and the corresponding safety indicator lights are lit up, which realizes rapid guidance for the initial evacuation.

[0108] Set a population density threshold to measure the size of the population;

[0109] Once the safety indicator lights for each escape route are activated, each escape route in the route set is divided into multiple route segments, and data is filtered based on the personnel density and personnel density threshold in each route segment.

[0110] Personnel density is the ratio of corridor space to the number of people in the corridor within a route segment;

[0111] Route segments with personnel density exceeding the personnel density threshold will be added to the diversion route segment set.

[0112] The diversion strategy is executed sequentially for each route segment in the set of diversion route segments;

[0113] If all route segments in the diversion route segment set have been traversed, then determine the personnel density of each route segment in the route set;

[0114] If the population density in all segments of each escape route in the route set is less than the population density threshold, then the route forks of each escape route in the route set are obtained in turn and entered into the fork set.

[0115] Each route fork in the fork set is filtered in turn, and the route forks through which multiple escape routes pass are entered into the fork adjustment set;

[0116] By sequentially executing adjustment strategies on each route junction within the junction adjustment set, and activating corresponding safety indicator lights based on the adjustment strategy results, pedestrian flow can be adjusted.

[0117] Otherwise, a diversion strategy will be implemented on route segments where the population density exceeds the population density threshold.

[0118] When an alarm is triggered, the corresponding safety indicator lights along the escape route will be activated, including:

[0119] Each escape route in the route set is divided into multiple route segments according to the turning points;

[0120] Activate in sequence all safety indicator lights on the walls of each escape route that are aligned with the direction of the route.

[0121] The step of sequentially executing the diversion strategy for each route segment in the diversion route segment set includes:

[0122] The escape routes corresponding to the elements in the set of diversion route segments are selected as the first route in turn;

[0123] The personnel gathering points corresponding to the first route will be designated as monitoring gathering points;

[0124] The first route is divided into multiple route segments according to the turning points, and these segments are entered into the first set.

[0125] Find the intersection of the first set and the set of branch route segments;

[0126] If the number of route segments in the intersection is equal to 1, then the route segments in the intersection will be taken as the target route segments;

[0127] Along the first route, select the route junction closest to the target route segment as the first junction;

[0128] Starting from the first fork in the road, obtain all escape routes other than the first route, and select the shortest escape route as the branching route, and enter the branching route into the route set.

[0129] The diversion routes are divided into multiple diversion route segments according to the route junctions;

[0130] Select the branching route segment closest to the first fork as the target branching route segment;

[0131] The escape direction in the target diversion route segment is designated as the first direction;

[0132] Obtain all safety indicator lights in the first direction of the target diversion route segment and enter the first set of safety indicators;

[0133] Sort all safety indicator lights in the first safety indicator set according to their distance from the first fork in ascending order and activate them.

[0134] The step of sequentially executing the diversion strategy for each route segment in the diversion route segment set includes:

[0135] If the number of route segments in the intersection is greater than 1, then all route junctions between adjacent route segments in the intersection are obtained, and the route junction closest to the monitoring aggregation point is selected as the first junction.

[0136] Starting from the first fork in the road, obtain all escape routes other than the first route, and select the shortest escape route as the branching route, and enter the branching route into the route set.

[0137] The diversion routes are divided into multiple diversion route segments according to the route junctions;

[0138] Select the branching route segment closest to the first fork as the target branching route segment;

[0139] The escape direction in the target diversion route segment is designated as the first direction;

[0140] Obtain all safety indicator lights in the first direction of the target diversion route segment and enter the first set of safety indicators;

[0141] Sort all safety indicator lights in the first safety indicator set according to their distance from the first fork in ascending order and activate them;

[0142] By monitoring the population density of each escape route segment in real time, the system activates a diversion strategy when a segment has excessively high population density. Population density identifies the segments requiring diversion, avoiding indiscriminate diversion and improving accuracy. The diversion strategy first identifies congested segments. If an escape route contains only one congested segment, the nearest junction to that segment is selected as the first junction. If an escape route contains multiple congested segments, the nearest junction to the population gathering point among adjacent congested segments is selected as the first junction. A new escape route is then found from the first junction as the diversion route. Finally, safety indicator lights in the corresponding directions on the diversion route are illuminated to guide people from the congested route to the new route. Starting from the first junction, the shortest escape route other than the congested route is selected as the final diversion route. To ensure the effectiveness and efficiency of traffic diversion routes, the system selects the intersections closest to congested sections as diversion points, reducing the distance people need to detour and improving diversion efficiency. This is particularly effective for situations with multiple congested sections; selecting the intersection closest to the gathering point among adjacent congested sections allows for earlier diversion, preventing further congestion. This diversion strategy considers both single and multiple congested sections, increasing its adaptability and better reflecting real-world conditions. Dividing the diversion routes into multiple segments and activating the corresponding safety indicator lights on the segment closest to the diversion point achieves segmented traffic guidance, preventing congestion at diversion intersections. By gradually illuminating the safety indicator lights on the diversion routes, people are guided to move slowly and orderly, avoiding confusion and crowding caused by simultaneously activating or deactivating safety indicator lights.

[0143] The step of sequentially executing the diversion strategy for each route segment in the diversion route segment set includes:

[0144] The escape direction in the target route segment is designated as the second direction;

[0145] Obtain all safety indicator lights in the second direction of the target route segment and input them into the second safety indicator set;

[0146] Sort each safety indicator light in the second safety indicator set according to its distance from the first fork in ascending order, and turn off all safety indicator lights in the second safety indicator set in sequence, while monitoring the personnel density in the target route segment in real time;

[0147] If the population density in the current target route segment is less than the population density threshold or all safety indicator lights in the second set of safety indicators are turned off, the diversion strategy will be stopped.

[0148] The process of sequentially filtering each route fork in the fork set and adding the forks along multiple escape routes to the fork adjustment set includes:

[0149] Select the route forks in the fork set as the target forks in sequence;

[0150] If the number of escape routes passing through the target fork is equal to 1, then a new route fork in the fork set is selected as the new target fork.

[0151] If the number of escape routes passing through the target fork is greater than 1, the target fork is added to the fork adjustment set, and a route fork in the fork set is reselected as the new target fork, until all route forks in the fork set have been traversed.

[0152] By selecting route intersections from the intersection set that are traversed by multiple escape routes and recording them into the intersection adjustment set, subsequent crowd flow adjustment strategies can be implemented. Through screening, route intersections that do not need adjustment are excluded, reducing the amount of computation required for subsequent processing and improving overall operational efficiency.

[0153] The process of sequentially executing adjustment strategies on each route junction within the junction adjustment set and activating corresponding safety indicator lights to adjust pedestrian flow based on the adjustment strategy results includes:

[0154] Select the route intersections from the intersection adjustment set as the adjustment intersections in sequence;

[0155] Mark all escape routes that pass through the adjusted fork as Route 2;

[0156] Each second route is divided into multiple branch route segments according to the route forks;

[0157] Select the route segment of each second route that passes through the adjusted junction and is closest to the adjusted junction, and enter it into the set of route segments of the adjusted junction;

[0158] The route segment with the highest population density in the set of branch route segments is designated as route segment number one.

[0159] Select any one of the remaining route segments from the set of branch road segments, excluding route segment number one, as route segment number two.

[0160] Obtain the average interval between people within Route 2;

[0161] Set an interval threshold for determining the average interval between people;

[0162] The average spacing between people is the ratio of the corridor length within Route 2 to the number of people within Route 2.

[0163] If the average interval between people in section 2 is less than the interval threshold, then the corresponding safety indicator light will be adjusted.

[0164] If the average interval between people in Route 2 is greater than or equal to the interval threshold, then any other route segment in the set of branch route segments except Route 1 is selected as the new Route 2, and the average interval between people in Route 2 is compared with the interval threshold.

[0165] If all branch road segments except for the first road segment in the branch road segment set have been traversed, then a new branch road segment in the branch road adjustment set is selected as the new adjustment branch road segment, and the adjustment strategy is executed.

[0166] By processing each route fork in the adjustment set sequentially, all escape routes passing through that fork are first obtained. Then, for each route, the last route segment before entering the fork is found. The personnel density of these route segments is compared, and the route segment with the highest personnel density is designated as Route Segment 1, with the remaining route segments designated as Route Segments 2. The average personnel interval is calculated for Route Segments 2. If the average personnel interval for Route Segment 2 is less than the interval threshold, it is determined that Route Segment 2 needs lighting adjustment. By iterating through each Route Segment 2, the route segments that need adjustment can be identified, ultimately achieving the goal of reasonable adjustment. If the average personnel interval for all Route Segments 2 is greater than or equal to the set threshold, it means that no adjustment is needed, and the process moves to the next fork. By designating the route segment with the most personnel as Route Segment 1, the smooth flow of the main evacuation route is prioritized. By iterating through the Route Segments 2, the safety indicator lights of congested route segments are gradually adjusted to avoid creating new congestion with a one-time adjustment. By calculating the average personnel interval, rather than simply the number of people, the degree of congestion of the route segment can be more accurately reflected, making the adjustment strategy more refined.

[0167] If the average interval between people within Route 2 is less than the interval threshold, the corresponding safety indicator light will be adjusted, including:

[0168] Set the distance threshold for selecting safety indicator lights;

[0169] Obtain the direction of rotation from line segment 1 to line segment 2;

[0170] The direction of rotation refers to the direction of rotation required to move from line segment one to line segment two;

[0171] If the rotation direction is to the left, then obtain all safety indicator lights on the right wall of line segment 2 that are in the same direction as the escape route of line segment 2 and whose distance from the first fork is less than the distance threshold, and enter them into the adjustment instruction set.

[0172] If the rotation direction is to the right, then obtain all safety indicator lights on the left wall of line segment 2 that are in the same direction as the escape route of line segment 2 and whose distance from the first fork is less than the distance threshold, and enter them into the adjustment instruction set.

[0173] Sort all safety indicator lights in the adjustment indicator set in ascending order of their distance from the adjustment junction;

[0174] If all safety indicator lights in the adjustment instruction set are activated, then turn off all safety indicator lights in the adjustment instruction set in sequence, and select a route junction in the junction adjustment set as the new adjustment junction to execute the adjustment strategy, until all route junctions in the junction set have been traversed;

[0175] If none of the safety indicator lights in the adjustment indicator set are activated, then a new route junction in the junction adjustment set is selected as the new adjustment junction, and the adjustment strategy is executed until all route junctions in the junction adjustment set have been traversed.

[0176] The direction of rotation from Route 1 to Route 2 is determined. Then, based on the rotation direction, safety indicator lights on the wall corresponding to Route 2, within a certain range of the fork in the road and aligned with the escape direction of Route 2, are selected and added to the adjustment instruction set. Next, the safety indicator lights in the adjustment instruction set are activated sequentially according to their distance from the fork. If all lights in the adjustment instruction set are activated, they are turned off sequentially, and the process moves to the next fork for adjustment; if not all lights in the adjustment instruction set are activated, they remain off, and the process moves to the next fork for adjustment. By selecting safety indicator lights within a certain range of the fork for adjustment, personnel can observe the safety indicator lights at the fork immediately, avoiding over-concentration at the fork and reducing the risk of congestion. Ordering the safety indicator lights in the adjustment instruction set according to their distance from the fork and activating them sequentially allows for gradual guidance of personnel, preventing sudden changes that could cause confusion.
