DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0026] like Figure 1 As shown, the present application provides an intelligent control method for fire evacuation in a subway station, the method is applied to an intelligent control system, the system is communicatively connected with a fire detector, an image acquisition device, an evacuation indicator light, and a UWB positioning electronic tag, including:

[0027] Step S100: obtaining a structural diagram of a safe evacuation passage of a subway station;

[0028] Step S200: obtaining a fire signal sent by the fire detector;

[0029] Specifically, the method provided in the present application is used to control the direction of the guide arrow of the evacuation indicator light when a fire occurs in a subway station, thereby helping the victims to evacuate quickly to a safe area. The fire detector transmits the fire signal to the intelligent control system through the signal transmission module as soon as possible. The image acquisition device is installed next to the evacuation indicator light, and the collected real-time image results are transmitted to the intelligent control system through the image transmission module. The communication connection between the system and the evacuation indicator light means that the system sends the guide arrow change direction instruction to the evacuation indicator light control module, and the UWB positioning electronic tag is placed in the work card of the front-line staff of the subway station to obtain the real-time positioning information of the front-line staff of the subway station. The UWB positioning electronic tag sends the real-time positioning information to the system, and then the system sends the warning information to the UWB positioning electronic tag. The structural diagram of all safe evacuation passages in the subway station is obtained, and when a fire occurs, the fire signal is sent to the intelligent control system as soon as possible through the fire detector, and the fire signal includes the location of the fire, the fire alarm time, etc. By obtaining the structural diagram of the subway station safe evacuation passage and the fire signal, information support is provided for the next step of obtaining a passable safe passage.

[0030] Step S300: obtaining a navigable safe evacuation passage according to the structural diagram and the fire signal;

[0031] In one embodiment, step S300 of the present application further includes:

[0032] Step S310: Obtaining fire location information according to the fire signal;

[0033] Step S320: obtaining a prohibited safe evacuation passage through the fire location information;

[0034] Step S330: obtaining the passable safe evacuation passage based on the structural diagram and the prohibited safe evacuation passage.

[0035] Specifically, the specific location of the fire point is obtained through the received fire signal, and the fire hazard area is set according to the specific location of the fire point. Through the fire hazard area, it can be known which safe evacuation passages are currently prohibited from passing, that is, the prohibited safe evacuation passage is obtained. Take Suzhou Bridge Station in the middle section of Beijing Metro Line 16 as an example. The building structure of the station is relatively complex, divided into an upper and lower double-layer platform structure, with a large flow of personnel. When a fire occurs on the second underground floor, the fire curtains of the four escalators leading to the first underground floor will not fall down, and these four escalators can be used as evacuation passages; when a fire occurs on the first underground floor, the fire curtains of the four escalators connecting the first and second underground floors fall down, and these four escalators cannot be used as evacuation passages. Then, according to the structural diagram of the safe evacuation passage of the subway station, the currently available safe evacuation passage, that is, the passable safe evacuation passage, is obtained. By obtaining the passable full evacuation passage, a basis is provided for the next step of changing the guide arrows of the evacuation indicator light.

[0036] Step S400: issuing a guide arrow direction change instruction to the evacuation indicator light through the passable safe evacuation passage, and obtaining a guide arrow direction change result;

[0037] In one embodiment, step S400 of the present application further includes:

[0038] Step S410: obtaining a navigable safe evacuation route according to the navigable safe evacuation passage;

[0039] Step S420: obtaining the direction indicated by the guide arrow of the evacuation indicator light based on the passable safe evacuation route;

[0040] Step S430: issuing a direction change instruction of a guide arrow to the evacuation indicator light according to the direction indicated by the guide arrow;

[0041] Step S440: the evacuation indicator light changes the direction of the guide arrow according to the guide arrow direction change instruction to obtain the guide arrow direction change result.

[0042] Specifically, a passable safe evacuation route can be obtained based on the currently passable safe evacuation passage. The passable safe evacuation route is a route pointing to a safe area, with a specific indication direction. The end point of the indication direction of the guide arrows of all evacuation indicator lights on the route connected in series is the safe area. The indication direction of the guide arrows of all evacuation indicator lights on the route is obtained through the passable safe evacuation route. Then the indication direction of the guide arrow is converted into a guide arrow change instruction and sent to the evacuation indicator light control module. The guide arrow change instruction should contain specific azimuth coordinates, such as: north, northeast, east, southeast, south, southwest, west, northwest, etc. It is not just to replace the original indication direction, but to change it according to the actual passable evacuation route. After the evacuation indicator light control module receives the guide arrow change instruction, it changes the indication direction of the guide arrow of the evacuation indicator light according to the instruction content, that is, obtains the guide arrow change result. By obtaining the guide arrow change result, the problem that the traditional non-centrally controlled evacuation indicator light cannot automatically change the evacuation arrow mark direction according to the fire situation can be solved.

[0043] Step S500: performing image acquisition on the direction change result of the guide arrow based on an image acquisition device to obtain the guide arrow image acquisition result;

[0044] Step S600: Compare the guide arrow direction change instruction with the guide arrow image acquisition result to obtain the guide arrow comparison result;

[0045] In one embodiment, step S600 of the present application further includes:

[0046] Step S610: Obtaining historical image information of the evacuation indicator light and its surroundings;

[0047] Step S620: constructing a historical image database according to the historical image information;

[0048] Step S630: recognizing the guide arrow image acquisition result based on the historical image database to obtain the guide arrow image acquisition and recognition result;

[0049] Step S640: Compare the guide arrow direction change instruction with the guide arrow image acquisition and recognition result to obtain the guide arrow comparison result.

[0050] Specifically, the image of the guide arrow of the evacuation indicator light is collected by an image acquisition device installed next to the evacuation indicator light, and a real-time image of the guide arrow is obtained, and the image contains information about the surrounding of the evacuation indicator light. The historical image information of the evacuation indicator light and its surroundings is obtained in advance, and the historical image information contains the characteristics and specific azimuth coordinates of the surrounding buildings, in order to help the intelligent control system distinguish the specific indication direction of the real-time image of the guide arrow to avoid misidentification of the direction. The historical image database is composed of the historical image information. The real-time image of the guide arrow is matched with the historical images in the historical image database to obtain the specific pointing direction of the real-time image of the guide arrow, that is, the guide arrow image acquisition and recognition result. Then, the nose tip guide arrow image acquisition and recognition result is checked to see if it is consistent with the specific pointing direction of the guide arrow change direction instruction issued, and the guide arrow comparison result is obtained. By obtaining the guide arrow comparison result, the fault problem of the guide arrow of the evacuation indicator light can be discovered in time.

[0051] Step S700: Based on the guide arrow comparison result, determine whether to generate warning information, and the warning information is used to remind station management personnel to take manual emergency plans.

[0052] In one embodiment, step S700 of the present application further includes:

[0053] Step S710: If the comparison results of the guide arrows are consistent, the guide arrows are used to guide the victims to quickly evacuate the fire scene;

[0054] Step S720: if the guide arrow comparison results are inconsistent, generating a warning message;

[0055] Step S730: sending the warning information to the subway station manager closest to the evacuation indicator light;

[0056] In one embodiment, step S730 of the present application further includes:

[0057] Step S731: obtaining the location information of the evacuation indicator lights for which the guide arrow comparison result is inconsistent;

[0058] Step S732: obtaining real-time positioning information of all subway station managers through UWB positioning electronic tags;

[0059] Step S733: obtaining the subway station manager closest to the evacuation indicator light based on the evacuation indicator light location information and the real-time location information.

[0060] Specifically, first, the positioning information of the fault evacuation indicator light is obtained through the intelligent control system. The UWB positioning electronic tag is placed in the work badge of the front-line staff of the subway station, and is used to obtain the real-time positioning information of the front-line staff of the subway station. The real-time positioning information of all subway station managers is obtained through the UWB positioning electronic tag. The path distance between the evacuation indicator light positioning information and the real-time positioning information is obtained. The path distance is obtained according to the structural diagram of the subway station, which refers to the shortest path for the subway station manager to reach the fault evacuation indicator light, not the straight-line distance between the two. The path distances are compared, and the one with the shortest distance is the subway station manager closest to the evacuation indicator light. By obtaining the nearest subway station manager, the fault problem can be dealt with in time to avoid serious personnel evacuation problems caused by the failure of the evacuation lamp.

[0061] Step S740: After receiving the warning information, the subway station manager guides the affected people to quickly evacuate the fire scene through a manual emergency plan.

[0062] Specifically, if the comparison results of the guide arrows are consistent, that is, the evacuation indicator light has not failed, there is no need to change it, and the disaster victims can quickly evacuate the fire scene and evacuate to a safe area under the guidance of the guide arrows. If the comparison results of the guide arrows are inconsistent, that is, the evacuation indicator light has failed, then the intelligent control system will generate an early warning message, and send the early warning message to the subway station manager closest to the evacuation indicator light. After receiving the early warning message, the subway station manager will rush to the fault area as soon as possible, and help the disaster victims to evacuate quickly through the artificial emergency plan arranged in advance, solving the technical problem that there is no complete set of evacuation indicator light guide arrow change methods, which cannot meet the requirements of the immediate evacuation plan, thereby better protecting the lives and property of subway passengers and subway staff.
