Fig. 1 is a schematic diagram of a crowd evacuation system in an emergency situation in accordance with an embodiment of the invention. As shown in fig. 1, the crowd evacuation system comprises: a server 200 and a plurality of street lamps 100;
each street lamp 100 comprises a sensor module, a lighting module, a communication module (see fig. 3) and a controller (not shown), the sensor module, the lighting module and the communication module are all connected with the controller, and the controller is connected with the server 200 through the communication module;
the sensor module is used for detecting whether an emergency occurs at the street lamp 100;
the controller is used for generating alarm information and sending the alarm information to the server 200 through the communication module when the sensor module detects that an emergency occurs;
the server 200 stores position coordinates of a plurality of street lamps 100, and the server 200 is configured to: after receiving the alarm information, acquiring a first position coordinate of the street lamp 100 for sending the alarm information; according to the first position coordinate, determining a second position coordinate of a safe place with the shortest effective distance from the street lamp 100 for sending the alarm information, wherein the effective distance is the distance of a road for people to pass through; determining target route information for crowd evacuation according to the first position coordinate, the second position coordinate and the route information with the shortest effective distance between the first position coordinate and the second position coordinate, wherein the route information with the shortest effective distance between the first position coordinate and the second position coordinate comprises the position coordinates of a plurality of street lamps 100, and the target route information comprises sequential arrangement information of the street lamps 100; a controller that transmits the target route information to the street lamp 100 corresponding to the position coordinates included in the target route information;
the controller is also used for controlling the light rays generated by the lighting module according to the sequential arrangement information when the target path information is received so as to form an identification arrow on the ground by using the light rays; the direction of the identification arrow is a direction in which one street lamp 100 points to a street lamp 100 adjacent to the street lamp 100 to evacuate a crowd with the identification arrow.
In the embodiment, whether an emergency occurs at the street lamp is detected by using a sensor module of the street lamp, when the sensor module detects the emergency, a controller generates alarm information and sends the alarm information to a server through a communication module, and the server generates target path information for crowd evacuation after receiving the alarm information, so that when the controller receives the target path information, the controller controls light rays generated by a lighting module according to sequence arrangement information included by the target path information, and an identification arrow is formed on the ground by using the light rays; the direction of the identification arrow is the direction that one street lamp points to the street lamp adjacent to the street lamp, so that people are evacuated by the identification arrow. Above-mentioned technical scheme can guarantee when emergency takes place, utilizes the street lamp to send the mode that guides the crowd to flee from the sign arrow of emergency emergence department and can effectively evacuate crowd.
It is understood that the emergency may be a fire or a leakage of harmful gas, for example, when the emergency is a fire, the sensor module may be an infrared sensor, a temperature sensor, etc.; also for example, in case of a harmful gas leakage in an emergency, the sensor module may be a gas detection sensor. The type of emergency and sensor module is not particularly limited herein.
The position coordinates may refer to longitude and latitude coordinates of each street lamp, or may be other expression modes of coordinates capable of representing the unique position of each street lamp, and are not specifically limited herein.
Since it is necessary to guide the crowd to move to a safe place closest to the place where the emergency occurs when the emergency occurs, it is noted that the safe place does not represent a safe place closest to a straight line from the place where the emergency occurs. This is because in many scenarios, the fastest safe place that can be really reached by the crowd is not the safe place closest to the straight line of the emergency place due to the influence of surrounding buildings (such as a fence), and therefore it is necessary to consider the factor of the effective distance. Wherein, the effective distance is the distance of the road for the crowd to pass through.
In an embodiment of the present invention, the server 200 determines the target route information for crowd evacuation according to the first position coordinate, the second position coordinate and the route information with the shortest effective distance between the first position coordinate and the second position coordinate, and performs the following operations:
step S1, obtaining initial arrangement information corresponding to the first position coordinate and final arrangement information corresponding to the second position coordinate according to the first position coordinate and the second position coordinate.
For example, the first position coordinate is (1, 4), the second position coordinate is (4, 1), the start arrangement information is the first bit, and the end arrangement information is the last bit.
Step S2, obtaining the position coordinates of the building between the first position coordinates and the second position coordinates.
In this step, the building located between the first position coordinate and the second position coordinate, specifically, the outline of the building intersects with the connecting line of the first position coordinate and the second position coordinate, and the building is referred to as the building located between the first position coordinate and the second position coordinate. The server 200 stores position coordinates of each street lamp and profile information of each building in advance, and the profile information of the building is represented by a connection line of a plurality of vertexes, that is, the profile information of each building includes the position coordinates of the plurality of vertexes.
Step S3, determining the position coordinate having the shortest effective distance from the first position coordinate and the position coordinate having the shortest effective distance from the second position coordinate, based on the position coordinate of the building and the route information having the shortest effective distance between the first position coordinate and the second position coordinate.
For example, each unit distance has a street lamp, such as coordinate points (1, 1), (1, 2) … … (1, n), (2, 1), (2, 2) … … (2, n), … … (n, 1), (n, 2), … … (n, n). When the first position coordinate is (1, 4), and the second position coordinate is (4, 1), the outline information of the building is a connection line of the position coordinates of (1.5, 8), (1.5, 7) … … (1.5, 1), and when the position coordinate with the shortest effective distance from the first position coordinate is (1, 3), because the coordinate point (2, 4) and the first position coordinate of (1, 4) are separated by the building, the crowd cannot pass through the entity of the building, and the building is considered not to be provided with a door; further, the remaining coordinate points (e.g., (1, 5), (0, 4)) are not position coordinates whose effective distance from the first position coordinate is shortest because they are all obtuse angles with respect to the line segment whose first position coordinate is (1, 4) and the line segments whose first position coordinate is (1, 4) and second position coordinate is (4, 1).
Similarly, the position coordinate having the shortest effective distance from the second position coordinate (4, 1) at this time is (3, 1).
Step S4, using the position coordinate with the shortest effective distance from the first position coordinate as the first position coordinate, using the position coordinate with the shortest effective distance from the second position coordinate as the second position coordinate, and skipping execution according to the first position coordinate and the second position coordinate to obtain the initial arrangement information corresponding to the first position coordinate and the ending arrangement information corresponding to the second position coordinate until the obtained first position coordinate and the obtained second position coordinate are the same.
The target route information can be obtained quickly by the algorithm of the shortest effective route of step S4.
In step S5, the process of obtaining a start arrangement information and a stop arrangement information is determined as a round-robin execution process.
Step S6, for each round-robin execution process, sequentially associating the start arrangement information obtained by the round-robin execution process with the start arrangement information obtained by the next round-robin execution process, and reversely associating the end arrangement information obtained by the round-robin execution process with the end arrangement information obtained by the next round-robin execution process to form the sequential arrangement information of each street lamp 100.
Following the example of step S3, the position coordinates of each street lamp are sequentially arranged as follows: (1, 4), (1, 3), (1, 2), (1, 1), (2, 1), (3, 1) and (4, 1).
Step S7, determining target route information for crowd evacuation according to the position coordinates and sequence information of each street lamp 100.
Next, in step S6, the sequence arrangement information of (1, 4) is the first bit, the sequence arrangement information of (1, 3) is the second bit, the sequence arrangement information of (1, 2) is the third bit, the sequence arrangement information of (1, 1) is the fourth bit, the sequence arrangement information of (2, 1) is the fifth bit, the sequence arrangement information of (3, 1) is the sixth bit, and the sequence arrangement information of (4, 1) is the last bit.
After the target path information is obtained, each street lamp can send out an identification arrow pointing to the next street lamp from the current street lamp, so that people can be evacuated by using the identification arrows.
In one embodiment of the present invention, the street lamp 100 further comprises a broadcasting module, and the broadcasting module is connected with the controller;
the broadcasting module is used for broadcasting audio for reminding people to evacuate when the controller receives the target path information.
In the embodiment of the invention, the broadcasting module is arranged to perform audio broadcasting in emergency, for example, "please run for 30 meters to the east after running for 50 meters to the north, and arrive at a safe place", so that the crowd evacuation effect is facilitated.
In an embodiment of the present invention, the street lamp 100 further includes a camera module, and the camera module is connected to the controller;
the controller is further used for detecting the face orientation of each person on the video sent by the camera module when the target path information is received, and if the face orientation of each person is detected to be opposite to the direction of the identification arrow, an emergency reminding instruction is sent to the broadcasting module, so that the broadcasting module broadcasts the audio corresponding to the emergency reminding instruction.
In the embodiment of the invention, the camera module is arranged, so that the controller can identify the face direction of the video sent by the camera module, and if the face direction of a person is detected to be opposite to the direction of the identification arrow, an emergency reminding instruction is sent to the broadcast module, so that people without direction sense can be effectively prevented from being evacuated towards a safe place correctly.
In one embodiment of the present invention, the street lamp 100 further comprises a display screen, wherein the display screen is connected with the controller;
the display screen is used for displaying an identification arrow corresponding to the current street lamp 100 when the controller receives the target path information.
In the embodiment of the invention, the display screen is arranged, so that how to evacuate people to a safe place quickly and correctly can be guided to the people group in a graphic and text manner, and the people group evacuation efficiency is further improved.
