[0026] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details.

[0027] In the description of this application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0028] References to "one embodiment" or "some embodiments" in this specification mean that one or more embodiments of the present application include a particular feature, structure, or characteristic described in conjunction with that embodiment. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof all mean "including but not limited to," unless otherwise specifically emphasized.

[0029] In order to illustrate the technical solution described in this application, specific embodiments are provided below.

[0030] See also Figure 1 , Figure 1The figure is a flow chart of an escape route planning method for a smart building provided in an embodiment of the present application. In this embodiment, the method is executed by a terminal device. It is understood that terminal devices include, but are not limited to, mobile phones, tablet computers, laptop computers, ultra-mobile personal computers (UMPCs), netbooks, and personal digital assistants (PDAs). The present embodiment of the present application does not impose any restrictions on the specific type of terminal device.

[0031] See also Figure 1 The escape path planning method provided in the embodiment of the present application includes but is not limited to the following steps:

[0032] In S100 , disaster location information of a building and first location information of a target object are acquired.

[0033] Exemplarily, the building may be an intelligent building, in which a plurality of temperature sensor alarms and / or a plurality of smoke sensor alarms may be preset; when a fire occurs in the intelligent building, the terminal device may obtain the disaster location information of the building through the preset temperature sensor alarms and / or smoke sensor alarms; therefore, the disaster location information may indicate the location of the temperature sensor alarm that generates the alarm signal, or may indicate the location of the smoke sensor alarm that generates the alarm signal.

[0034] Without loss of generality, in order to improve the accuracy of detecting the location of disasters, smart buildings can also be pre-installed with multiple high-precision cameras and multiple position sensors; when a fire or earthquake occurs in the smart building, the terminal device can first obtain multiple frames of real-time scene images of the smart building through the high-precision camera, and then use image recognition technology to identify specified objects in the multiple frames of real-time scene images, such as identifying burning objects or collapsed walls in the real-time scene images, and then obtain the position of the object or the wall in the smart building through the position sensor, and obtain the first position information of the target object through the position sensor, wherein the first position information represents the real-time position of the target object in the smart building, and the target object can be a person in the smart building.

[0035] In S200 , a character portrait corresponding to a target object is obtained from a pre-established object database.

[0036] Specifically, the character portrait can be generated based on the basic attribute information of the target object, and the basic attribute information includes the dimensional information of the character attribute dimension of the target object; the terminal device can pre-establish an object database, and then construct the character portrait of the target object in the object database; when constructing the character portrait of the target object, the terminal device can obtain the basic attribute information of the target object through a variety of sensors preset in the smart building, or set the target object's customized attribute information as the basic attribute information of the target object.

[0037] For example, when a person enters a smart building, the terminal device can set the person as a target object, and then obtain the average walking length of the target object through a ranging sensor, and then obtain the average walking speed of the target object through a speed sensor, and through image recognition technology, preliminarily identify the age and gender of the target object in the multi-frame real-time scene image, and then construct a character portrait of the target object based on the average walking length, average walking speed, age and gender of the target object, thereby realizing the pre-construction of a character portrait of the target object before a disaster occurs; when a disaster occurs, the terminal device can directly obtain the character portrait corresponding to the target object from the pre-established object database, thereby improving response efficiency.

[0038] In S300 , escape path information is generated based on the disaster location information, the first location information, and the character portrait, and the escape path information is sent to a terminal corresponding to the target object.

[0039] Exemplarily, the terminal device can generate escape path information that is strongly related to the target object based on the disaster location information, the first location information and the character portrait, and then send the escape path information to the terminal corresponding to the target object; the target object can learn the details of the escape path that best suits him / her through the escape path information, and when the target object escapes according to the escape path, the target object's chance of survival can be greatly improved.

[0040] In some possible implementations, in order to provide an escape route that best suits the target object and facilitates the escape of people in the building, please refer to Figure 2 Step S300 includes but is not limited to the following steps:

[0041] In S310 , based on the first location information, a surrounding area of the target object is searched until the second location information of the building is determined.

[0042] Specifically, the surrounding area represents an area centered on the first location information, that is, the real-time location of the target object in the smart building, and covered by a preset first distance value as a radius. The first distance value can be determined in combination with the actual usable area of the smart building, and the second location information represents the location corresponding to any safety exit in the smart building; please refer to Figure 3 , Figure 3 The circle filled with black inside represents the target object, and the area surrounded by the dotted circle represents the surrounding area of the target object. It should be noted that Figure 3 The size of the middle peripheral area is only an example, and the specific size is not limited. In some other possible implementations, the size of the peripheral area can be any size.

[0043] Without loss of generality, when a disaster occurs in a smart building, the terminal device can search the surrounding area of the target object based on the first location information until the location of any safe exit is determined; in another possible implementation method, the terminal device can search the surrounding area of the target object until the locations of all safe exits in the surrounding area are determined, thereby providing more escape options for people in the building.

[0044] In some possible implementations, in order to adapt to the more complex spatial layout of buildings in actual application scenarios, please refer to Figure 4 Step S310 includes but is not limited to the following steps:

[0045] In S311 , based on the first location information, a search is performed with a preset second distance value to determine whether there is any safety exit in the surrounding area of the target object.

[0046] Specifically, the terminal device can take the real-time position of the target object in the smart building as the center, and then search whether there is any safety exit in the surrounding area of the target object with a preset second distance value; if there is any safety exit in the surrounding area of the target object, but the number of corners and / or the total length of the escape path for the target object to reach the safety exit exceeds the preset benchmark value, the terminal can continue to search the surrounding area until another safety exit is found.

[0047] Exemplarily, the terminal device may be preset with a corner reference value and a total escape path length reference value, wherein the specific value of the corner reference value may be 6, and the total escape path length reference value may be 40 meters. When the terminal device calculates that the number of corners of the escape path for the target object to reach the safe exit is 7 and the total length of the escape path is 68 meters, the terminal device may continue to search for another safe exit.

[0048] In S312 , if there is no safety exit in the surrounding area, the second distance value is modified according to a preset distance increasing rule until the second location information of the building is determined.

[0049] Specifically, the distance increasing rule may be based on the current second distance value, and the second distance value may be increased in sequence by a preset multiple of the target object's average walking distance; see Figure 3 If the terminal device determines that there is no safe exit in the surrounding area, the terminal device can modify the second distance value according to the preset distance increment rule until the location of any safe exit is determined, thereby facilitating the search for a safe exit closest to the target object and multiple safe exits that the target object can choose, which is conducive to the escape of people in the building.

[0050] In S320, at least one escape route is generated according to the first location information and the second location information.

[0051] Specifically, when there is a safety exit in the surrounding area of the target object, the terminal device can generate an escape path with the real-time position of the target object in the smart building as the starting point and the position corresponding to the safety exit as the end point; when there are multiple safety exits in the surrounding area of the target object, the terminal device can generate multiple escape paths with the real-time position of the target object in the smart building as the starting point and the positions corresponding to the multiple safety exits as the end points.

[0052] In S330, escape route information corresponding to at least one escape route is determined based on the disaster location information and preset building space information.

[0053] Specifically, the building space information can be pre-stored in the memory of the terminal device, and the building space information includes at least the number of corners information, third position information, escape path width information and escape path length information; wherein, the third position information represents the position of the fire-fighting equipment preset in the smart building. When the personnel in the building arrive at the location of the fire-fighting equipment, the personnel in the building can obtain fire-fighting equipment such as gas masks and fire extinguishers, thereby increasing the probability of escape of the personnel.

[0054] For example, see Figure 5 , Figure 5 The white filled circle indicates the location of the disaster, such as the location of a burning object or the location of an obstacle that fell from the ceiling to the ground due to an earthquake. Figure 5 The triangle in represents the third position information, Figure 5The dashed line with an arrow in the middle represents an escape path. The terminal device can determine the escape path information corresponding to each escape path based on the disaster location information and building spatial information. Each escape path information corresponds to one escape path. This escape path information allows occupants to at least know the number of corners they need to pass to reach the safe exit along the escape path, the number of firefighting equipment in the escape path, the width of the escape path, and the total length of the escape path. This facilitates occupants to obtain relevant information and escape smoothly.

[0055] In S340 , a target escape route is selected from at least one escape route based on the character portrait.

[0056] For example, when there is only one escape path, the terminal device can directly select the escape path as the target escape path; when there are multiple escape paths, the terminal device can select the target escape path that best suits the target object from multiple escape paths based on the character portrait, thereby facilitating the escape of people in the building and improving safety.

[0057] In S350, the escape route information corresponding to the target escape route is sent to the terminal corresponding to the target object.

[0058] Exemplarily, after the terminal device selects the target escape path, the terminal device may send the escape path information corresponding to the target escape path to the terminal corresponding to the target object, for example, by sending the escape path information to the target object's mobile phone in the form of a multimedia message.

[0059] In some possible implementations, in order to increase the target object's chance of escape, please refer to Figure 6 Step S330 includes but is not limited to the following steps:

[0060] In S331 , for at least one escape path, a plurality of escape path dimensions associated with the escape path are generated according to the disaster location information, the number of corners information, the third location information, the escape path width information, and the escape path length information.

[0061] Exemplarily, the terminal device can generate multiple escape path dimensions associated with each escape path based on the disaster location information, number of corners information, third location information, escape path width information and escape path length information corresponding to the escape path; in a possible implementation, the terminal device can generate a first path dimension representing the degree of danger based on the distance between the location of the disaster and the location of the safe exit; the terminal device can generate a second path dimension representing the degree of safety based on the distance between the location of the fire-fighting equipment and the location of the target object; the terminal device can generate a third path dimension representing the degree of feasibility based on the escape path width information and the escape path length information.

[0062] In S332 , the escape route dimension that meets the preset conditions is determined as the escape route information.

[0063] Specifically, after the terminal device generates multiple escape path dimensions associated with the escape path, the terminal device can determine the escape path dimensions that meet the preset conditions as escape path information, thereby omitting the escape path dimensions that do not meet the preset conditions and reducing the impact of invalid data.

[0064] In some possible implementations, to determine the most suitable escape path for the target object, please refer to Figure 7 Step S340 includes but is not limited to the following steps:

[0065] In S341 , for at least one escape path, a correlation index between the target object and the escape path is calculated based on the dimensional information of each escape path dimension in the escape path information and the character attribute dimension associated with the escape path dimension in the character portrait.

[0066] For example, when there are multiple escape paths, the terminal device can calculate a correlation index between the target object and the escape path based on the dimensional information of each escape path dimension within the escape path information and the character attribute dimensions associated with the escape path dimensions in the character portrait. In one possible implementation, the terminal device can generate a first character dimension representing the ability value based on the target object's average walking distance and average walking speed, and the first character dimension can be associated with the first path dimension and the second path dimension respectively. The terminal device can also generate a second character dimension representing the execution level based on the target object's age and gender, and the second character dimension can be associated with the third path dimension.

[0067] In S342 , a target escape path is determined from the at least one escape path based on the correlation index and a preset index threshold.

[0068] Exemplarily, when there are multiple escape paths, the terminal device can respectively compare the preset index threshold and the correlation indexes corresponding to the multiple escape paths; when the correlation index is greater than or equal to the preset index threshold, the terminal device can determine the escape path as the target escape path; when there are multiple correlation indicators greater than or equal to the preset index threshold, the terminal device can determine the escape path with the maximum value of the correlation index as the target escape path.

[0069] In some possible implementations, to improve the calculation accuracy of the correlation index, step S341 includes but is not limited to the following steps:

[0070] Import the dimension information of each escape path dimension in the escape path information and the character attribute dimension associated with the escape path dimension in the character portrait into the preset correlation index calculation function to determine the correlation index

[0071] Specifically, the correlation index calculation function is:

[0072]

[0073] Where, Relevance(Objct i ,Route i ) represents the correlation between the escape path and the target object; i Indicates the weight coefficient of the element of the i-th first dimension in the character attribute dimension; n represents the number of dimensional information included in the character attribute dimension. For example, when there are five character attribute dimensions, the specific value of n is 5; Object i Indicates the value of the element of the i-th first dimension in the character attribute dimension. The first dimension can be the first character dimension or the second character dimension. i It represents the value of the element of the i-th second dimension in the escape path dimension. The second dimension can be the first path dimension or the second path dimension. C represents the preset correction value. The specific value of the correction value can be customized by the user.

[0074] The implementation principle of the escape path planning method based on smart buildings in the embodiment of the present application is: the terminal device can first obtain disaster location information and first location information, then generate at least one escape path, and then calculate the correlation index between the character portrait corresponding to the target object and the escape path, and according to the correlation index, determine a target escape path that best fits the target object from at least one escape path, and then send the escape path information corresponding to the target escape path to the terminal corresponding to the target object. The target object can obtain relevant information about the escape path with the highest escape probability through the terminal, thereby facilitating the target object to escape.

[0075] It should be noted that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
