The embodiment of the invention mainly provides a method for generating an escape route in a personalized manner according to a user portrait. By the method, the escape route can be generated more accurately and effectively.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for generating an escape route according to a user profile according to a first embodiment of the present invention. In an embodiment of the invention, the method for generating the escape route in a personalized manner according to the user portrait comprises the following steps:
step S11: acquiring user information and current position information through a mobile terminal;
step S12: determining a current position coordinate in a preset scene model according to the current position information; the preset scene model comprises escape exit coordinates;
step S13: acquiring a current fire position coordinate;
step S14: determining at least one target escape route according to environmental factors, the current fire position coordinates, the current position coordinates and the escape exit coordinates in the scene model;
step S15: matching user figures in the picture database according to the user information, and determining the priority of the user according to the user figures;
step S16: and distributing the target escape routes corresponding to the priorities to the mobile terminal according to the priorities.
It is to be understood that the term "mobile terminal" in steps S11 to S16 can be understood as an electronic device carried by the user, and can be a mobile phone with communication function, a tablet, or a wearable device, the term "current location information" mentioned in step S11, i.e. the current location of the user, and the term "user information" mentioned in step S12, i.e. one dimension of the user' S portrait, can be obtained by hardware of the electronic device, such as a positioning device carried by the mobile terminal.
Specifically, when the electronic device is used to obtain the user information and the current location information, the bluetooth application may be used to access an address book, a map, and a GPS positioning system of the user terminal, and when the user information and the current location information are obtained by means of software of the mobile terminal, data in a software system developed for a mobile tool by itself generally includes some registration information of the user, such as: when the software is installed, the user can be inquired whether the reading of the position information is allowed or not and whether the reading of the installation list is allowed or not;
if the software system does not have the information, the information can be acquired in question and answer access to the user, such as the following examples: after the user selects the device terminal, the user may apply for accessing the user or obtain related information of the user through an external source, such as user information obtained on software that the software authorizes to access, for example: the method allows login by adopting an account of a third party, and can acquire some basic user information from the third party.
Further, in the step S11 to the step S14, a scene needing to escape is simulated, specifically, the three-dimensional graph development software may be combined to virtualize environmental features in the real scene, so that the real scene is converted into a scene model with position information, and then the current position coordinates in the preset scene model are determined according to the current position information; the preset scene model comprises an escape exit coordinate, and then the current fire position coordinate is obtained, so that the current position coordinate, the escape exit coordinate and the scene model can be utilized to generate the target escape route with the shortest path. The Dijkstra algorithm may be used to find the current position coordinates in the following manner:
referring to fig. 2, fig. 2 is a diagram illustrating a scene model of a method for generating an escape route according to a user figure in a personalized manner according to a first embodiment of the invention. The illustrated scene model is only used as an example for illustrating the embodiment, and does not limit the method provided by the embodiment of the invention in any way. Assuming that in the scene model, a user is located at a position corresponding to a current position coordinate x1, first, the current position information of the user is obtained through a Positioning device of a mobile terminal of the user, it should be noted that when a real scene is a flat building, that is, when the real scene is only a floor, a Global Positioning System (GPS) or a base station may be preferentially adopted to position the current position of the mobile terminal, but if the building to which the user belongs is a high-rise building (at this time, the GPS or base station has a poor signal and cannot perform position Positioning), the method may be performed in a manner including, but not limited to, Wireless Fidelity (Wi-fi) Positioning, Radio Frequency Identification (RFID) electronic tag Positioning or bluetooth Positioning; optionally, positioning Wi-fi, and calculating the current position information of the mobile terminal by combining a triangulation positioning method with each RSSI value detected by the mobile terminal by adopting a Nearest Neighbor rule classification algorithm (K-Nearest Neighbor) according to the distance between the mobile terminal and a network point. It is to be understood that the above-described methods are well within the skill of those in the art, and that the embodiments of the present invention are described merely to illustrate the feasibility of the embodiments and to limit the scope of the embodiments of the present invention, and not to unduly limit the scope of the embodiments.
Further, the current position coordinate x1 corresponding to the user in the scene model is matched based on the current position information of the user. Further, in the scene model shown in the embodiment of the present invention, three escape exit coordinates, which are x3, x6, and x7, are preset, and according to Dijkstra algorithm, A, B, C three escape routes are respectively provided from the current position coordinate of the user to the escape exit coordinate in the scene model; the corresponding distances are respectively as follows:
1、Short(A)＝x1→x2→x3＝d12+d23；
2、Short(B)＝x1→x4→x5→x6＝d14+d45+d56；
3.Short(A)＝x1→x4→x7＝d14+d47：
in the above formula, short represents the shortest distance path, and the score from x1 to x7 represents the scene modelIn which d is12、d23、d14、d45、d56、d47The distance weights are preset distance weights, namely A, B, C routes are formed from the current position coordinate to the escape exit coordinate of the user in the simulated scene according to the current position information of the user at the moment; then, the operation is carried out in step S13, and two escape routes are determined A, C as target escape routes according to the current fire position coordinates x 5.
Referring to fig. 3, fig. 3 is a flowchart illustrating step S14 of a method for generating an escape route according to a user image in a personalized manner according to a first embodiment of the present invention.
Further, the step of determining at least one target escape route for one direction of step S14, that is, combining the environmental factors, the current fire position coordinates, the current position coordinates, and the escape exit coordinates in the scene model, may include the steps of:
step S141: determining an escape route between the escape exit and the mobile terminal according to the escape exit coordinate and the current position coordinate;
step S142: matching the fire position coordinates with the escape route;
step S143: removing the escape route successfully matched;
step S144: and calculating the escape distances of the remaining escape routes, and performing distance sequencing on the escape distances to generate at least one target escape route.
A, B, C three escape routes are respectively arranged from the current position coordinates of the user to the escape exit coordinates in the scene model; the corresponding distances are respectively as follows:
1. line a ═ x1 → x2 → x 3;
2. the line B is x1 → x4 → x5 → x 6;
3. the line C is x1 → x4 → x 7;
the fire position coordinates correspond to x5, the fire position coordinates are matched with the escape route, and if the route comprises the fire position coordinates, the fire position coordinates are eliminated, so that the escape route line B which is successfully matched is eliminated, namely the rest:
1、Short(A)＝x1→x2→x3＝d12+d23；
3.Short(C)＝x1→x4→x7＝d14+d47；
and further comparing the distances between the short (A) and the short (C), calculating the escape distances of the remaining escape routes, and performing distance sequencing on the escape distances to generate the sequencing of the target escape routes.
It can be understood that, after the nearest escape route (i.e. the target escape route) planned by the system is determined in the three-dimensional virtual building scene model (scene model), a corresponding virtual route indicating element (target escape route) is generated in the three-dimensional virtual building scene model (preset scene model) according to the route; the route indication element may be an arrow or a character with a 3D effect, which is not limited in this embodiment;
referring to fig. 4, fig. 4 is another flowchart of a method for generating an escape route according to a user profile in a personalized manner according to a first embodiment of the invention. The method provided by the embodiment of the invention can also comprise the following steps:
step S21: matching voice files in the corpus database according to the target escape route;
step S22: calculating the position relation between the current position coordinate and the fire position coordinate and the escape exit coordinate;
step S23: and under the condition that the position relation meets a preset triggering condition, triggering the voice file to broadcast.
It can be understood that steps S21 to S23 mainly provide a voice broadcast function, and the specific scheme may be as follows:
referring to fig. 5, fig. 5 is a partial schematic structural diagram of a method for generating an escape route according to a user figure in a personalized manner according to a first embodiment of the present invention. In order to implement steps S21 to S23, a plurality of broadcast speakers 10 may be provided on the escape route through which the user passes, and the broadcast speakers 10 perform voice broadcast when the user passes through; for example, when the user is located in the area with the corresponding coordinate position of a1, the processor 20 firstly uses the area where the current position coordinate of the user is located as the trigger condition according to the current position coordinate of the collected user, for example, when the current position coordinate of the user enters the a1 area, the broadcast speaker 10 of a1 is triggered to broadcast, and when the user does not reach the a1 area or leaves the a1 area, the broadcast voice is not needed.
Further, the voice file in the corpus database is firstly matched according to the target escape route of the corresponding user, specifically, the voice file is obtained by firstly matching corpus codes in the corpus database according to the target escape route, then selecting sound source digital signal data according to the corpus codes, and outputting analog signals to the digital signal data through a digital-to-analog converter, namely, the voice file is obtained in the form of a data packet, the serial communication transmission data can be transmitted through a network cable or wireless transmission, preferably, the latter, and the wireless transmission mode can be any one of bluetooth transmission, ZigBee transmission and Wifi transmission, so that the voice file is transmitted to the broadcasting speaker 10.
It is understood that if the public address loudspeaker 10 does not have a power amplifier, the power amplifier corresponding to the public address loudspeaker 10 should be set to perform sound source broadcasting of the amplified voice file at the public address loudspeaker 10.
Further, the contents of the voice file may include user information, and navigation information corresponding to a target escape route of the user, such as from a1 to a2 to a3, may be: li x, please turn right. The duration of the voice file can be set to be short, and the voice file can be broadcasted in a concise and clear mode. The reason for adding the user information is to prevent misleading when the user is at a bifurcation, for example, if a plurality of users pass through the bifurcation at the same time, the users may be misled by other people's target escape routes if the user information is not broadcasted.
Referring to fig. 6, fig. 6 is another flowchart of a method for generating an escape route according to a user profile in a personalized manner according to a first embodiment of the invention. The method provided by the embodiment of the invention can further comprise the following steps:
step S31: reading a compass of the mobile terminal to acquire current orientation information in the process of escaping by a user;
step S32: comparing the current orientation information with the target escape route to obtain a deviation error;
step S33: and when the deviation error is larger than a preset threshold value, prompting the deviation error.
It can be understood that the current position information of the mobile terminal corresponds to the current coordinates in the predetermined scene model one to one; when a real mobile terminal (user) moves in a building, the system simulates a corresponding virtual scene picture at a first person viewing angle in a three-dimensional virtual building scene model (a preset scene model) according to the movement of the position of the mobile terminal in the real building and the change of the orientation; accordingly, since the mobile terminal is provided with the gyroscope sensor, when the moving route of the mobile terminal in the real building deviates from the planned route and the deviation error is greater than the preset threshold, the deviation error can be automatically generated in the virtual scene picture. The embodiment of the invention has the beneficial effects that: the mobile terminal displays the escape route and the virtual route indicating element in the virtual reality scene picture at the first time, and can intuitively guide the user to a target escape exit; and when the user deviates the route, the user is informed in time by showing the deviation error of the current position of the user, so that the condition that the user gets lost or walks by mistake is reduced.
Referring to fig. 7, fig. 7 is a flowchart illustrating a method for generating an escape route according to a user profile in a personalized manner according to a second embodiment of the invention. As a specific mode of the first embodiment, the second embodiment of the present invention may further include the following steps:
step S14: determining at least one target escape route according to environmental factors, the current fire position coordinates, the current position coordinates and the escape exit coordinates in the scene model;
step S15: matching user figures in the picture database according to the user information, and determining the priority of the user according to the user figures;
wherein, the step S14 of matching the user portrait in the portrait database according to the user information, and the determining the priority of the user according to the user portrait includes:
step S151: reading user information in the mobile device;
step S152: matching the user portrait in the portrait database according to the user information;
step S153: calculating the escape difficulty corresponding to the user portrait according to the user portrait;
step S154: and determining the priority according to the escape difficulty.
It is understood that, by presetting the user image database, steps S151 to S152 may be understood as performing data source analysis on the user information, and performing weight marking according to the dynamic information and the static information in the user information, in the embodiment of the present invention, the user image is defined to include at least one of the age, the physical condition, the professional characteristics, the income, and the gender of the user.
The user portrait aims to analyze the user and finally label the user with the escape difficulty. For example, for the user's age. The weight may be set to 0.6 below age 40, 0.8 between age 40 and 60, and 0.9 between age 60 and 80. And the final label weight may be: the user escape difficulty weight is the attenuation factor multiplied by the age weight multiplied by the physical condition weight, and those skilled in the art should understand that the model for calculating the user escape difficulty weight is only an example reference, and a specific weight calculation mode needs secondary modeling.
In step S154, the priorities are determined according to the difficulty of escaping, that is, the priorities are sorted according to the difficulty of escaping, for example, if the difficulty of escaping for the user a is 0.98, and the difficulty of escaping for the user b is 0.6, it can be determined that the user a is relatively difficult to escape, and the priority of the user a is higher, and the mobile terminal is assigned with a target escaping route with a shorter distance.
In accordance with the foregoing, the user representation includes at least one of: user age, physical condition, occupational characteristics, income, gender.
Referring to fig. 8, fig. 8 is a flowchart of step S153 of a method for generating an escape route according to a user image in a personalized manner according to a second embodiment of the invention. As a modification of the second embodiment, the step of calculating the escape difficulty corresponding to the user profile in step S153 according to the user profile comprises the following steps:
step S1531: according to the user portrait, the average moving speed of the user is estimated through a preset formula;
step S1532: and sequencing according to the average moving speed to obtain the escape difficulty.
It is understood that, when the weight is calculated, a dimension is added, that is, the average moving speed of the user is used as a reference value, it should be noted that the average moving speed here is only a presumption result from the user portrait and big data analysis, and is a factor generated by the target escape route of the user in a static state, and does not represent the average moving speed value of the user in a real scene.
Referring to fig. 9, fig. 9 is another flowchart of a method for generating an escape route according to a user representation in a personalized manner according to a second embodiment of the invention. The method provided by the embodiment of the invention also comprises the following steps:
step S41: presetting the maximum number of persons accommodated in each target escape route in unit time;
step S42: calculating escape time according to the average moving speed and the escape distance of the target escape route;
step S43: calculating the average escape time according to the escape time and the maximum number of people accommodated;
step S44: under the condition that the number of the target escape routes distributed to the mobile terminals reaches the maximum number of the accommodated persons; temporarily removing the target escape route within the average escape time;
step S45: and upgrading the priorities corresponding to the remaining target escape routes.
It can be understood that the maximum number of persons accommodated in each target escape route in unit time, namely, the maximum capacity number of persons is set, so that the situation that the same target escape route is recommended by more persons is prevented, the situation that the persons are crowded and trampled is caused, and secondary harm is avoided. For example, the survival route a is a route with the highest priority level, which is defined as route 1 herein, and according to the real environment, the upper limit of the number of people that the route can pass through in ten minutes is preset to be 30 people, and according to the average moving speed and the escape distance of the user, the time that the user passes through the escape route a, that is, the survival time, can be determined, assuming that the user (mobile terminal) recommending the escape route a is full of 30 people (stations), and the average escape time of the 30 people is 5 minutes, the escape route a is no longer recommended to other people within the 5 minutes, so that the user is prevented from entering the escape route a, and at this time, other target escape routes are subjected to priority upgrade, that is, the route 2 originally becomes route 1, and other users (mobile terminals) continue to perform sequencing recommendation according to the priority level according to the changed target survival routes.
After 5 minutes, under normal conditions, the user can be determined to have escaped from the route a, and the route a continues to be the target escape route of the line 1 as a recommendation.
In summary, the application provides a method for generating an escape route in a personalized manner according to user figures, which includes the steps of matching the user figures in a picture database according to user information, and determining the priority of a user according to the user figures; therefore, the target escape route suitable for the portrait of different users is recommended. The method has the advantages that firstly, the survival rate under the condition of fire disaster is increased, compared with the traditional condition that all users recommend the shortest route, the moving speed and the physical condition of the users are not considered, all the users are easy to crowd the same route, escape is not carried out in sequence, treading or crowding is easy to happen at the moment, and the survival rate is reduced on the contrary. And secondly, the escape efficiency of a fire scene can be ensured, when a user escapes, the moving speed of the same route is consistent according to the distribution of the user portrait, and the relatively equal time efficiency is maximized.
