The area of the building in which people are distributed may be a room in which people are distributed and/or a passageway in which people are distributed.

When the area is a room, the area information and the person distribution information of the room may be obtained in two ways, including:

the first mode is as follows: the first image acquisition device detects whether personnel are distributed in a room where the first image acquisition device is located through acquired images, if the personnel are distributed, personnel distribution information of the room is detected, the personnel distribution information comprises information such as the number of the personnel in the room, and a first notification message is sent to the control equipment, wherein the first notification message comprises equipment identification of the first image acquisition device and the personnel distribution information. The control equipment receives a first notification message sent by the first image acquisition device, extracts the equipment identification and the personnel distribution information in the room from the first notification message, and acquires the area information of the room from the corresponding relation between the equipment identification and the area information according to the equipment identification.

The first image acquisition device is arranged in a room of a building, can shoot the room where the first image acquisition device is located in real time to obtain an image, detects the image, detects that people are distributed in the room if the image is detected to include a human body image, and further counts the number of the human body images included in the image to obtain the number of the people in the room.

Before executing the step, an image set comprising a plurality of images including human body images in various forms and in motion states can be input to the first image acquisition device, so that the first image acquisition device trains, adjusts and optimizes the first image acquisition device according to each image in the image set, and the accuracy of detecting whether people are distributed in a room and counting the number of the people in the room is improved.

Optionally, when the first image capturing device is arranged in a room of a building, the device identifier of the first image capturing device and the area information of the room may be stored in a corresponding relationship between the device identifier and the area information.

The second mode is as follows: the first image acquisition device shoots a room where the first image acquisition device is located to obtain an image, and the image and the equipment identification of the image are sent to the control equipment. The control equipment receives the image and the equipment identification, detects whether personnel are distributed in the room according to the image, determines the room as the room with the personnel distributed if the personnel are distributed, detects personnel distribution information in the room according to the image, and acquires the area information of the room from the corresponding relation between the equipment identification and the area information according to the equipment identification.

Optionally, the control device detects the image, if it is detected that the image includes the human body image, it is detected that people are distributed in the room, and the number of the human body images included in the image is further counted to obtain the number of the people included in the room.

When the area is a channel, the area information and the personnel distribution information of the channel can be acquired in two ways, including:

the first mode is as follows: the second image acquisition device detects whether personnel are distributed in the channel where the second image acquisition device is located through the acquired images, if the personnel are distributed, personnel distribution information in the channel is detected, the personnel distribution information comprises information such as the number of the personnel in the channel, and a first notification message is sent to the control equipment, wherein the first notification message comprises the equipment identification of the second image acquisition device and the personnel distribution information. The control equipment receives a first notification message sent by the second image acquisition device, extracts the equipment identification and the personnel distribution information in the channel from the first notification message, and acquires the area information of the channel from the corresponding relation between the equipment identification and the area information according to the equipment identification, wherein the area information of the channel comprises the position of the channel.

Before executing the step, an image set comprising a plurality of images including human body images in various forms and in a motion state can be input to the second image acquisition device, so that the second image acquisition device trains, adjusts and optimizes the second image acquisition device according to each image in the image set, and the accuracy of the second image acquisition device in detecting whether people are distributed in a channel is improved.

Optionally, when the second image capturing device is disposed in a channel of the building, the device identifier of the second image capturing device and the area information of the channel may be correspondingly stored in the corresponding relationship between the device identifier and the area information.

The second mode is as follows: and the second image acquisition device shoots the channel where the second image acquisition device is located to obtain an image and sends the image and the equipment identifier of the image to the control equipment. The control equipment receives the image and the equipment identification, detects whether personnel are distributed in the channel according to the image, determines the channel as the channel with the distributed personnel and detects personnel distribution information in the channel according to the image if the personnel are distributed, wherein the personnel distribution information comprises the number of the personnel in the channel, and acquires the area information of the channel from the corresponding relation between the equipment identification and the area information according to the equipment identification.

Optionally, the control device detects the image, if it is detected that the image includes a human body image, it is detected that people are distributed in the channel, and the number of the human body images included in the image is further counted to obtain the number of the people in the channel.

Step 302: the control equipment acquires channel information of each channel in the building through an image acquisition device installed in each channel in the building.

The channel information of the channel includes indication information indicating whether the channel is a normal channel and position information of the channel. Specifically, whether the first channel can normally pass is detected according to an image shot by an image acquisition device installed on the first channel, wherein the first channel is any one channel in a building; if the first channel is detected to be normally passable, determining the first channel as a normal channel; and acquiring the position information of the first channel from the corresponding relation between the equipment identifier and the position information of the channel according to the equipment identifier of the image acquisition device, and generating the channel information of the first channel, wherein the channel information comprises indication information indicating that the first channel is a normal channel and the position information of the first channel.

Optionally, if it is determined that the first channel is an abnormal channel, channel information of the first channel may also be generated, where the channel information includes indication information indicating that the first channel is an abnormal channel and location information of the first channel.

In implementation, the control device may obtain the channel information of the channel through the following two obtaining manners, which are respectively:

the first mode is as follows: and the second image acquisition device detects whether the channel where the second image acquisition device is located can normally pass or not in real time, and if the channel where the second image acquisition device is located can normally pass, the second image acquisition device sends a second notification message to the control equipment, wherein the second notification message comprises the equipment identifier of the second image acquisition device. The control equipment receives a second notification message sent by a second image acquisition device, extracts the equipment identifier from the second notification message, acquires the position information of the channel from the corresponding relation between the equipment identifier and the position information of the channel according to the equipment identifier, and generates the channel information of the channel, wherein the channel information comprises indication information used for indicating that the channel is a normal channel and the position information of the channel.

The second image acquisition device is an image acquisition device arranged in a passage of a building, and can be shot in real time to obtain an image of the passage. The passageway of the building may comprise a staircase or corridor or the like in the building. In this embodiment, at least one second image recording device is arranged in a passage of the building, by means of which all passages within the building are covered in their entirety.

The situation that the channel cannot normally pass is generally as follows:

one is that a collapsed road section occurs in the channel, the width of an uncollapsed area in the collapsed road section is smaller than a preset first threshold value, and the length of the collapsed area is larger than a preset second threshold value.

The width of an uncollapsed area in the collapsed road section is smaller than a preset first threshold value, which indicates that the uncollapsed area cannot accommodate a person to pass through; the length of the collapse area in the collapse section is larger than a preset second threshold value, and the collapse area cannot be crossed by people. Therefore, when the width of the non-collapsed region in the collapsed section is smaller than the preset first threshold value and the length of the collapsed region is larger than the preset second threshold value, it indicates that the person cannot pass through the collapsed section from the collapsed region.

The other is that an obstacle appears on the channel, the height of the obstacle exceeds a preset height threshold value, and the intervals between the two sides of the channel and the obstacle are smaller than a preset interval threshold value.

The height of the obstacle exceeds a preset height threshold value, which indicates that the obstacle is high and a person cannot cross the obstacle; the interval between the two sides of the channel and the obstacle is smaller than a preset interval threshold value, which indicates that the interval between any side of the channel and the obstacle is small, and people cannot pass through the interval. Therefore, the height of the obstacle exceeds a preset height threshold value, and the intervals between the two sides of the passage and the obstacle are smaller than a preset interval threshold value respectively, so that the situation that a person cannot cross the obstacle is shown.

The second image acquisition device detects whether the channel where the second image acquisition device is located can normally pass or not in real time, and the operation can be as follows:

the second image acquisition device identifies the edge of the channel where the second image acquisition device is located from the shot image; if the edge of the channel comprises the edge of a collapse area, determining a collapse section comprising the collapse area, acquiring the length of the collapse area according to the edge of the collapse area comprised in the collapse section, and acquiring the width of an uncollapsed area according to the edge of the uncollapsed area comprised in the collapse section, when the width of the uncollapsed area is smaller than a preset first threshold value and the length of the collapse area is larger than a preset second threshold value, determining that the collapse section cannot normally pass, otherwise, determining that the collapse section can normally pass.

If the edge of the channel comprises the edge of the obstacle, the height of the obstacle is obtained according to the edge of the obstacle, the intervals between the two sides of the channel and the obstacle are respectively obtained according to the edge of the obstacle and the edges of the two sides of the channel, when the height of the obstacle exceeds a preset height threshold value and the intervals between the two sides of the channel and the obstacle are smaller than a preset interval threshold value, the fact that the road section comprising the obstacle cannot normally pass is determined, and otherwise, the fact that the road section comprising the obstacle can normally pass is determined.

And if the road section including the obstacle and the collapse road section do not exist in the passage, or the road section including the obstacle and the collapse road section can normally pass through, the second image acquisition device determines that the passage can normally pass through.

Optionally, the second image capturing device may further detect whether people are distributed in the channel according to the captured image, and if people are distributed, obtain the evacuation time of the channel according to the captured image, and correspondingly, the second notification message sent by the second image capturing device to the control device may further include the evacuation time, and the channel information of the channel generated by the control device may further include the evacuation time of the channel.

Optionally, the operation of obtaining the evacuation time of the channel may be:

the second image acquisition device detects whether the images shot by the second image acquisition device include human body images or not, if yes, the second image acquisition device detects that people are distributed in the channel where the second image acquisition device is located, the moving speed of the people in the channel is obtained, and the evacuation time of the communication is calculated according to the channel length of the channel and the moving speed of the people; if not, it is detected that the passage has no people distribution, the evacuation time of the passage can be set to a preset value.

The second image acquisition device obtains the personnel's moving speed in its place passageway, can be:

the second image acquisition device acquires a first image currently shot by the second image acquisition device, acquires a second image shot before the first image, calculates the moving distance of each person in the first image according to the second image and the first image, calculates the moving speed of each person according to the moving distance of each person and the shooting time interval between the first image and the second image, and calculates the average speed according to the moving speed of each person, wherein the average speed is the moving speed of the person in the channel.

In this embodiment, the first image and the second image are separated by at least one frame of image.

When the second image capturing device is arranged in the passageway of the building, the device identifier of the second image capturing device and the position information of the passageway may be stored in a corresponding relationship between the device identifier and the position information of the passageway.

The second mode is as follows: and the second image acquisition device shoots the channel where the second image acquisition device is located to obtain an image and sends the image and the equipment identification of the image to the control equipment. The control equipment receives the image and the equipment identification, detects whether the channel can normally pass or not according to the image, determines that the channel is a normal channel if the channel can normally pass, acquires the position information of the channel according to the equipment identification, and generates the channel information of the channel, wherein the channel information of the channel comprises the indication information of whether the channel is the normal channel or not and the position information of the channel.

The control device detects whether the passage is normal or not, and reference may be made to the detection process of the second image capturing device in the first mode, which is not described in detail herein.

Step 303: the control equipment generates at least one indoor passing route of each area according to the area information of each area where people are distributed and the channel information of the channels in the building, and the indoor passing route of each area is used for communicating the area with the outside of the building.

Each indoor passing route corresponds to an exit, and people in the area can escape from the exits of the indoor passing routes along the indoor passing routes of the area.

Step 304: the control device calculates a transit time for each of at least one indoor transit route of the areas.

Specifically, for each area with people distributed therein and for each indoor passing route in at least one indoor passing route of the area, the evacuation time of each channel included in the indoor passing route is obtained, and the passing time of the indoor passing route is calculated according to the evacuation time of each channel included in the indoor passing route.

Optionally, the evacuation time of each channel included in the indoor passing route may be accumulated to obtain the passing time of the indoor passing route.

Step 305: for each area with people distributed, the control equipment selects one indoor passing route from at least one indoor passing route of the area as an escape route of the area according to the passing time of each indoor passing route of the area.

Alternatively, when the area is a room in a building where people are distributed, referring to fig. 4, the step may be implemented by the following process, including:

3051: when a building comprises a room with people distributed, selecting one indoor passing route with the shortest passing time from at least one indoor passing route of the room as an escape route of the room.

Optionally, a playing device may be disposed in the room, and the playing device may be controlled to play the escape route, so that the person in the room leaves along the escape route.

Optionally, the playing device may be a sound box or a speaker.

The indoor passing route with the shortest passing time is selected as the escape route, so that people in the room can escape in the fastest time, and the escape efficiency is improved.

3052: when a building comprises a plurality of rooms with distributed people, when only one indoor passing route of a first room is available, whether a second room exists is determined, at least one section of channel overlapping exists between the indoor passing route of the first room and the indoor passing route of the second room, and the second room only has one indoor passing route.

The first room is any one of the plurality of rooms, and the second room is the other one of the plurality of rooms except the first room.

3053: if the second room exists, the first evacuation room and the second evacuation room are determined in the first room and the second room according to the number of persons in the first room and the number of persons in the second room, and the indoor passage route for evacuating the first room is determined as the escape route for evacuating the persons in the first room.

The control device can play the escape route of the room evacuated firstly through the playing device so that the people evacuated firstly in the room leave firstly.

Specifically, a first evacuation time at which the persons in the first room evacuate the building is calculated from the number of persons in the first room and the passage time of the indoor passage route of the first room, and a second evacuation time at which the persons in the second room evacuate the building is calculated from the number of persons in the second room and the passage time of the indoor passage route of the second room; when the first evacuation time is shorter than the second evacuation time, the first room is determined as a first evacuation room and the second room is determined as a second evacuation room, otherwise, the second room is determined as a first evacuation room and the first room is determined as a second evacuation room.

For the first evacuation time, calculating the first time when the people in the first room leave the first room according to the number of the people in the first room and the number of the people capable of leaving the first room in the preset unit time, and adding the first time with the passing time of the indoor passing route of the first room to obtain the first evacuation time.

Similarly, for the second evacuation time, a second time when the person in the second room leaves the second room is calculated from the number of persons in the second room and the number of persons who can leave the second room in the preset unit time, and the second time is added to the transit time of the indoor transit route in the second room, resulting in the second evacuation time.

Optionally, after the indoor passing route of the room evacuated firstly is determined as the escape route corresponding to the room evacuated firstly, a target room can be determined in the building, the target room is an unmanned room in the building, the distance between the target room and the exit of the indoor passing route of the room evacuated firstly is smaller than the distance between the room evacuated later and the exit, a playing device in the room evacuated later is controlled to play the position information of the target room, and the target room is used for arranging the personnel transferred from the room evacuated later. The persons in the evacuation room are transferred to the target room according to the played position information of the target room.

Wherein the floor on which the target room is located may be the same as the floor on which the room was evacuated first.

For example, referring to fig. 5, assuming that the first room to be evacuated is a first room, the first room is a 3 rd floor, and the second room is a 4 th floor, an indoor passing route corresponding to the first room is determined as an escape route of the first room, and then people in the first room leave first.

Then, an unmanned room can be found in the 3 rd building as a target room, so that the people in the second room can be transferred to the target room. Therefore, when the person in the first room leaves, the person in the second room can leave from the target room, and the escape efficiency is improved.

If the indoor passing routes of the second room are provided with a plurality of routes, one of the routes is overlapped with the indoor passing route of the first room, one indoor passing route of the first room can be directly determined as the escape route of the first room; when the escape route is allocated to the second room, one indoor passing route corresponding to the first room may be removed from the plurality of indoor passing routes of the second room, then one indoor passing route with the shortest passing time is selected for the second room from the remaining indoor passing routes, and the selected indoor passing route is determined as the escape route corresponding to the second room.

3054: and if the second room does not exist, determining the indoor passing route of the first room as the escape route of the personnel in the first room.

3055: when there are a plurality of indoor passage routes of the first room, it is determined whether there is a third room having at least one indoor passage route, there is at least one passage overlap between the indoor passage route of the first room and the indoor passage route of the third room, and the first room and the third room are two different rooms.

3056: and if the third room exists, selecting one indoor passing route as the escape route of the personnel in the first room according to the passing time of each indoor passing route in the first room, selecting one indoor passing route as the escape route of the personnel in the third room according to the passing time of each indoor passing route in the third room, and avoiding overlapped passages between the two selected escape routes.

Optionally, one indoor passing route is selected from the multiple passing routes of the first room as an escape route for the people in the first room according to the passing time of each indoor passing route of the first room, one indoor passing route is selected from at least one passing route of the third room as an escape route for the people in the third room according to the passing time of each indoor passing route of the third room, and no overlapped passage exists between the two selected escape routes.

3057: and if the third room does not exist, selecting one indoor passing route as the escape route of the personnel in the first room according to the passing time of each indoor passing route in the first room.

Optionally, when the area is a section of passage in which people are distributed in the building, one indoor passing route may be selected from each indoor passing route in the area as the escape route corresponding to the area.

Optionally, the control device selects one indoor passing route as the escape route corresponding to each passage according to the passing time of each indoor passing route of the passage with the personnel.

Alternatively, an indoor traffic route with the shortest transit time may be selected.

In this embodiment, since the first image capturing device and the second image capturing device capture images in real time, that is, the operations in steps 301 to 305 are executed in a circulating manner, the control device may obtain, in real time, area information of an area where people are currently distributed in the building, people distribution information of the area, at least one indoor traffic route of the area, and select one indoor traffic route from the at least one indoor traffic route of the area as an escape route of the area according to the people distribution information of the area where people are distributed and/or the at least one indoor traffic route. That is, at a certain time, the control device may select a certain indoor passage route for a certain area as the escape route, and at another time, the control device may select another indoor passage route for the area as the escape route.

In the embodiment of the invention, at least one indoor passing route of the area and the passing time of each fixed indoor passing route in the at least one indoor passing route are determined according to the area information of the area where people are distributed and the channel information of the channels in the building; then, according to the passing time of each indoor passing route in the area, one indoor passing route is selected for the area to serve as an escape route, so that the indoor passing route with high escape efficiency can be distributed for the area to serve as the escape route, and the escape efficiency of personnel is improved. When the room is provided with the people, when two rooms with two overlapped indoor passing routes exist and only one indoor passing route exists in each room, the room to be evacuated first and the room to be evacuated later are determined according to the number of the people in the two rooms, the overlapped indoor passing route is distributed to the room to be evacuated first, the people evacuating first in the room are evacuated first, and the people evacuating later in the room are transferred to a target room capable of escaping more quickly, so that the escape efficiency is further improved.
