In one embodiment, the safety alarm signal includes a fire signal, where the fire signal is a signal sent to the control terminal by a fire detector in the building after detecting a fire, and is used to remind the control terminal of the occurrence of the fire in the building, where the fire signal is transmitted in a manner of a key signal, an electrical signal, or a voice signal, and the control terminal may obtain the fire signal through a signal sent by the fire detector. When the fire information sent by a plurality of fire detectors in a building is obtained, the position information, the fire information and the smoke information of a fire source in the building can be determined, and meanwhile, the spreading state, the spreading direction and the development state of the fire can be predicted according to different fire information sent by the fire detectors at different time.
As shown in fig. 2, before step S200, the method further includes:
and step S120, acquiring fire detection data sent by the fire detectors in each floor.
The fire detector comprises a temperature sensor, a smoke detection sensor, an infrared sensor and an ultrasonic sensor, the fire detector is used for detecting whether a fire disaster occurs at the position, and sending a fire signal to the control terminal when the fire disaster signal is monitored, wherein the temperature sensor can detect temperature information at the current position, the smoke detection sensor can detect smoke amount information at the current position, the infrared sensor can detect thermal infrared information at the current position, and the ultrasonic sensor can detect position information of a fire source
In step S140, a fire area is determined based on the fire detection data.
By acquiring the fire information sent by the fire detectors on each floor in the building, the position information, the fire information and the smoke information of the fire source in the building can be determined, so that the fire area is determined.
In one embodiment, after step S200, the method further includes:
and step S300, acquiring fire detection data in real time, and dynamically updating fire area information according to the acquired fire detection data.
The spreading state, the spreading direction and the development state of the fire can be predicted according to different fire information sent by the fire detector at different time. Since the fire is easily spread when a fire occurs, when a fire occurs at one location, the fire may spread to other location areas after a certain time, and thus if an escape route is determined according to the location information of the fire source and the escape route is not changed, the escape route may be a route directed to the fire due to the spread of the fire, and thus the escape route may give an erroneous guidance to evacuees. Therefore, after the control terminal acquires the fire signal, the control terminal can continuously acquire fire information sent by other fire detectors, and determine fire area information according to the fire information so as to dynamically plan and determine an escape path again.
As shown in fig. 3, in an embodiment, the fire detection data includes corresponding parameters of the location of the fire source and the fire spread range, and before step S400, the method further includes:
step S340, obtaining the position information of the preset security exit.
The travel passage, the house structure, the safety exit and the like of each floor are stored in the plane structure parameter information of the building which is stored in advance, and at this time, each preset safety exit of each floor is obtained in the plane structure parameter information of the building.
And step S360, determining that a path far away from the fire source and leading to the safety exit is a first escape path according to the fire detection data.
In step S380, it is determined that the path far from the fire spreading range and leading to the safety exit is the second escape path.
The escape paths of all floors can be different, but the escape paths in all floors are escape exits pointing to the safety exits, and a user can safely escape according to the escape paths. However, it should be noted that when the fire is great and the entire floor passage is located in the fire source, the escape route above the floor in the fire is a route for the evacuee to get away from the fire source.
In an application example, for example, the position information of the fire source is the middle right position of 7 floors, wherein the coordinate information of the fire source is determined to be the middle right position according to the fire detection data, wherein the control terminal acquires that three safety exits are arranged in the building and are respectively arranged at the left side, the right side and the middle position, at this time, the escape path determined at the position close to the middle position is a position far away from the fire source (the middle right position) and a path leading to the safety exit, at this time, although the safety exit is arranged in the middle, the safety exit is close to the fire source or needs to pass through the fire source to lead to the safety exit, at this time, the escape path cannot be used as the safety exit to determine the escape path, and at this time, the escape path leading to the safety exits at the left side and the right side is the first escape path. According to the fire detection data, the fire spreading range is determined to be 6 layers to 9 layers, the escape route at the middle position of 6 layers to 9 layers can not be determined as the route escaping from the safety exit at the middle position, wherein the escape route at the lower floor of 6 layers and the floor above 9 layers can be determined as the route close to the safety exit because the risk of fire spreading is less, at the moment, although the fire happens at the middle position close to the right, when the lower floor of 6 layers and the floor above 9 layers can avoid the fire spreading to a higher degree, the safety exit towards the middle can be selected as the escape route to be the second escape route under the close condition, so that the escape personnel can escape towards the safety exit more quickly.
In one embodiment, the updating of the indication information of each escape prompting device comprises:
the indication information of each escape prompting device is converted from preset information into target information, and the target information at least comprises one of current floor information, a fire source position, a fire spreading range, first distance information between the current escape prompting device and the fire source position and second distance information between the current escape prompting device and a safety exit.

In the normal state, the emergency sign lamp is displayed as fire propaganda or normal safety indication information, such as indicating a safety passage and direction, indicating stairs and direction, indicating an elevator and direction, indicating a toilet and reversing, and the like, and at the moment, the emergency sign lamp is used as a common information indication (or display) lamp. For example, when the emergency sign lamp is arranged at the middle left position of the 12 floors, and the right side of the emergency sign lamp is provided with the safety exit, the emergency sign lamp displays that the right side is the safety exit. When a fire disaster occurs in the position close to the right side in the middle of the 10 floors, the controller in the current emergency sign lamp controls the display content to be changed from preset information into target information according to the acquired control signal. In one embodiment, after the current emergency sign lamp receives the control signal sent by the control terminal, the content of the control signal is analyzed, and it is determined that the current emergency sign lamp is located in 11 floors, the fire source is located in 10 floors, the first distance between the current emergency sign lamp and the fire source is 3M, the second distance between the current emergency sign lamp and the safety exit is 10M, the escape direction is leftward, and at this time, the floor information, the first distance information, the floor information of the fire source, the escape direction, and the second distance information of the current emergency sign lamp are alternately displayed on the current emergency sign lamp. Wherein the escape direction is indicated as a fixed display in the present embodiment, which is provided to the evacuee to determine the escape direction. In the present embodiment, as shown in fig. 5(b1), the distance between the current escape prompting device and the safety exit, the escape direction, and the floor information of the emergency sign lamp are displayed as a display combination; as shown in fig. 5(b2), the distance from the current escape prompting device to the location of the fire source, the escape direction, and the floor information of the fire source are displayed as one display combination. At the moment, the escape personnel can determine that the current emergency sign lamp is positioned on 11 floors according to the information displayed by the current emergency sign lamp, the distance between the fire disaster and the next floor (10 floors) is 10M, and the distance between the fire disaster and the fire source is only 2M, so that the escape personnel can quickly escape towards the left escape direction according to the displayed information, but not towards the right-side closer safety exit. It should be noted that, in the alternate display of the display information, a combination mode of other information can be selected, which is not limited herein, and is used for displaying a larger pattern and less information, so as to avoid the problem that the information is difficult to be recognized by the evacuee when all the information is displayed in the display area of the emergency sign lamp at the same time. It should be noted that, when the different display combinations are displayed, the colors displayed by the different display combinations can be correspondingly changed, for example, when the floor information of the emergency sign lamp is displayed, the first color can be used for displaying; when the floor information of the fire source is displayed, the second color can be used for displaying, so that the escape personnel can visually recognize each information. It should be noted that when receiving a fire signal sent by a fire detector, the control terminal continuously obtains the fire signal sent by each fire detector, dynamically determines an escape path, a distance between the fire source and the emergency sign lamp, position information of the fire source and the like according to the fire signal, and dynamically sends a control signal to each emergency sign lamp, so that each emergency sign lamp dynamically changes display contents according to the received control signal, and the display contents are provided to escape personnel for escape.
