Description

Technical Field

[0001] The present invention relates to the technical field of scenic spot emergency broadcasting, and in particular to a scenic spot management method and system based on an emergency broadcasting platform. Background Art

[0002] Generally, tourist attractions are relatively large in area. Therefore, an emergency broadcast system will be deployed in each tourist attraction. The emergency broadcast system is connected to the monitoring system in the scenic area. The emergency broadcast system includes sound columns, loudspeakers, receivers and amplifiers installed at key points in the scenic area, as well as the emergency broadcast control platform in the main control room. The emergency broadcast system can play scenic spot tour precautions and music when no emergency occurs. When some emergencies occur, it can be used, for example, to broadcast missing persons and alarms for tourists entering restricted areas.

[0003] More and more people visit tourist attractions during holidays, especially during summer and winter vacations. Many parents travel with their children and their families. However, children are prone to run away when their parents are distracted. In the existing technology, when people are separated, guardians usually go to the broadcasting room to report the missing persons. However, the scenic area is large, and it is inefficient for staff to search one by one. In addition, the scenic area is noisy and the broadcast sound is likely to be ignored. This method lacks intelligent analysis technology, and the human cost of management is high, resulting in a slow response to such emergencies. Summary of the invention

[0004] The purpose of the present invention is to provide a scenic area management method and system based on an emergency broadcast platform, which combines monitoring equipment and an emergency broadcast platform. When an alarm message is received, it is automatically analyzed and broadcasted in the first time, without the need for users to actively go to the emergency broadcast platform to broadcast, thereby improving the response speed of emergencies.

[0005] To achieve the above objectives, this application provides the following solutions: In a first aspect, the present application provides a scenic area management method based on an emergency broadcasting platform, and the emergency broadcasting platform performs the following steps: S1. Receive the alarm information sent by the guardian terminal, where the alarm information includes the disconnection time and disconnection location when the guardian terminal is disconnected from the associated wristband terminal, and an image of the target person wearing the associated wristband terminal taken when the guardian terminal is bound to the associated wristband terminal; S2. According to the disconnection time and disconnection location, retrieve from the monitoring system all monitoring devices within a preset range of the disconnection location after the disconnection time; S3, sorting the monitoring devices according to the straight-line distance from the disconnection location, and sequentially acquiring the monitoring videos captured by each monitoring device; S4. Match the target person in each surveillance video according to the target person image, and record the time when the target person appears in the surveillance video and the installation location of the corresponding surveillance device; S5. Sort the installation positions according to the time of appearance to generate a motion track, send the motion track to the guardian terminal in real time, and control the broadcasting device on the motion track to broadcast.

[0006] In some specific implementations, the process of uploading the alarm information in step S1 is: The guardian terminal monitors the connection status between the guardian terminal and the associated wristband terminal in real time. When it is detected that the connection between the guardian terminal and the associated wristband terminal is disconnected, the disconnection time and disconnection position are recorded at this time, and it is determined whether the guardian terminal and the associated wristband terminal can be reconnected within the first preset waiting time. If they can be reconnected, the recorded disconnection time and disconnection position are deleted. If they cannot be reconnected, the alarm information is uploaded.

[0007] In some specific implementations, the specific process of step S3 is: S31, obtaining the installation positions of monitoring devices within a preset range of the disconnection position, and calculating the straight-line distance between each monitoring device and the disconnection position; S32, obtaining a preset scenic spot tour route, classifying each monitoring device according to the scenic spot tour route, and obtaining the monitoring video of each monitoring device after the disconnection time; S33, storing all monitoring devices on the same scenic spot tour route into an analysis list according to the straight-line distance from near to far, to obtain a plurality of analysis lists.

[0008] In some specific implementations, the specific process of step S4 is: S41, first obtaining, according to the disconnection location, monitoring videos of all monitoring devices within a first distance range from the disconnection location at the disconnection time point; S42, matching the target person image with the image frame captured from the surveillance video. If the surveillance video can match the target person, the matched target person is marked in the surveillance video, and the position of the target person is continuously tracked; S43, obtaining an analysis list of monitoring devices corresponding to the matched monitoring videos, and obtaining the monitoring videos of each monitoring device in the analysis list in turn; S44, matching the target person in each surveillance video according to the target person image, and recording the time when the target person appears in the surveillance video and the installation location of the corresponding surveillance device.

[0009] In some specific implementations, in step S42, if the target person can be matched in the monitoring video, the movement direction of the target person is analyzed to obtain the movement direction of the target person, and the movement direction of the target person is notified to the guardian terminal.

[0010] In some specific implementations, the warning information also includes the name and age of the person wearing the associated wristband terminal, and step S5 also includes the following steps: According to the matching analysis list, the broadcasting devices on the scenic spot tour route corresponding to the analysis list are obtained, the broadcasting information is generated according to the name and age, and the broadcasting information is inserted into each broadcasting device.

[0011] In some specific embodiments, when it is detected that the connection between the guardian terminal and the associated bracelet terminal is disconnected, both the guardian terminal and the associated bracelet terminal will issue a vibration reminder. When the connection is restored within the first preset waiting time, the vibration reminder is cancelled. When the connection is not restored within the first preset waiting time, the associated bracelet terminal immediately plays the voice reminder received in advance from the guardian terminal.

[0012] In some specific implementations, the specific process of analyzing the action direction of the target person is as follows: When the target person can be matched in the surveillance video, the starting position of the picture frame corresponding to the target person appearing in the surveillance video and the ending position of the picture frame corresponding to the target person leaving the surveillance video are recorded; According to the coordinates of the starting position and the end position, the direction of the end position relative to the starting position is calculated, and the direction is notified to the guardian terminal as the movement direction of the target person.

[0013] In the second aspect, a scenic area management system based on an emergency broadcasting platform is provided, including a guardian terminal, an associated wristband terminal, and an emergency broadcasting platform, wherein the guardian terminal is communicatively connected to the emergency broadcasting platform, and the guardian terminal is communicatively connected to the associated wristband terminal, wherein: The guardian terminal is used to bind with the associated wristband terminal, and take a picture of the person wearing the associated wristband terminal for storage. When the connection with the associated wristband terminal is detected to be disconnected, an alarm message is sent to the emergency broadcast platform. The alarm message includes the disconnection time and location when the guardian terminal is disconnected from the associated wristband terminal, and the image of the target person wearing the associated wristband terminal taken when the guardian terminal is bound with the associated wristband terminal; The emergency broadcast platform is used to receive the alarm information sent by the guardian terminal, and according to the disconnection time and disconnection location, retrieve all monitoring devices within the preset range of the disconnection location after the disconnection time from the monitoring system; Sort the monitoring devices according to their straight-line distances from the disconnection location, and sequentially obtain the monitoring videos captured by each monitoring device; Match the target person in each surveillance video according to the target person's image, and record the time when the target person appears in the surveillance video and the installation location of the corresponding surveillance equipment; The installation locations are sorted according to the time of appearance to generate a movement trajectory, the movement trajectory is sent to the guardian terminal in real time, and the broadcasting equipment on the movement trajectory is controlled to broadcast.

[0014] In some specific implementations, the guardian terminal is used to monitor the connection status between the guardian terminal and the associated wristband terminal in real time, and when it is detected that the connection between the guardian terminal and the associated wristband terminal is disconnected, the disconnection time and disconnection position at this time are recorded and a vibration reminder is issued, and it is determined whether the guardian terminal and the associated wristband terminal can be reconnected within the first preset waiting time. If they can be reconnected, the recorded disconnection time and disconnection position are deleted and the vibration reminder is cancelled. If they cannot be reconnected, the alarm information is uploaded; The associated bracelet terminal is used to issue a vibration reminder when it detects that the connection with the associated bracelet terminal is disconnected. When the connection is restored within the first preset waiting time, the vibration reminder is cancelled. When the connection is not restored within the first preset waiting time, the associated bracelet terminal immediately plays the voice reminder received in advance from the guardian terminal.

[0015] The inventive concept of this application is: The scenic area is large. When some emergencies occur, such as when some people who need to be accompanied by a guardian are lost and scattered, the corresponding information is usually broadcast to the broadcasting equipment in the entire scenic area through the emergency broadcast platform and patrolled by staff. This method lacks intelligent analysis technology, and the manpower cost of management is high, and the response speed to such emergencies is slow.

[0016] In this application, a guardian terminal is set up, and the target person who needs to be monitored wears an associated bracelet terminal. The target person is monitored in real time on the guardian terminal according to the connection status of the guardian terminal and the associated bracelet terminal of the target person, thereby reducing the redundant calculation amount of the emergency broadcast platform. Only when the guardian terminal sends an alarm message to the emergency broadcast platform will it trigger the corresponding monitoring video to be retrieved from the monitoring system, analyze the monitoring video, find the real-time movement trajectory of the target person, and notify the guardian to search on the movement trajectory. By automatically uploading the alarm information, the emergency broadcast platform analyzes the alarm information and sends it to the user. The guardian does not need to go to the emergency broadcast center to broadcast it, which can improve the response speed to emergencies. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The relative arrangement of components and steps, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.

[0020] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0021] Additionally, descriptions of well-known structures, functions, and configurations may be omitted for clarity and conciseness.One of ordinary skill in the art will recognize that various changes and modifications may be made to the examples described herein without departing from the spirit and scope of the present disclosure.

[0022] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0023] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0024] Example 1 like Figure 1 As shown, this embodiment provides a scenic area management system based on an emergency broadcast platform, including a guardian terminal, an associated wristband terminal, and an emergency broadcast platform. The guardian terminal is connected to the emergency broadcast platform in communication, and the guardian terminal is connected to the associated wristband terminal in communication, wherein: The guardian terminal includes a vibration module, an alarm module, a microphone, a GPS positioning module, a photo storage module and a first communication module which are communicatively connected to the first main control module; The associated bracelet terminal includes a vibration module, a speaker, a second communication module and a GPS positioning module that are communicatively connected to the second main control module; the guardian terminal and the associated bracelet terminal are communicatively connected via the first communication module and the second communication module; Among them, the photo storage module is used to take an image of the target person wearing the associated bracelet terminal when the guardian terminal and the associated bracelet terminal are bound, and is used to upload the image to the emergency broadcast center for personnel identification and matching when it is necessary to find someone later. In this embodiment, the guardian terminal can be installed on the guardian's mobile phone, and there is no need to worry about information leakage. The associated bracelet terminal has a unique identification code, so that the guardian terminal needs to re-bind the associated bracelet terminal each time. The vibration module is controlled by the first main control module, and a vibration reminder is issued when the first communication module and the second communication module are disconnected. The pickup is used to record the guardian's voice reminder information when the guardian terminal and the associated bracelet terminal are bound and stored in the first main control module and sent to the associated bracelet terminal through the first communication module. In this way, when the guardian and the target person are separated, the second main control module detects that the first communication module and the second communication module are disconnected, and the control speaker can play the voice reminder information to comfort the target person. The GPS positioning module is used to locate the wearer's location information, and the associated bracelet terminal regularly uploads the positioning information to the guardian terminal. When the first communication module and the second communication module are disconnected, the positioning information uploaded by the associated bracelet terminal for the last time is uploaded to the emergency broadcast platform as the disconnected position. The first communication module and the second communication module both use paired short-distance connection communication, such as Bluetooth connection, WIFI hotspot connection, etc., so that when a certain distance is exceeded and the connection is disconnected, the guardian can be notified in time.

[0025] Specifically, the guardian terminal is used to bind with the associated wristband terminal, and take a portrait picture of the person wearing the associated wristband terminal for storage. When it is detected that the connection with the associated wristband terminal is disconnected, an alarm message is sent to the emergency broadcast platform through the alarm module. The alarm message includes the disconnection time and disconnection location when the guardian terminal is disconnected from the associated wristband terminal, and an image of the target person wearing the associated wristband terminal taken when the guardian terminal is bound with the associated wristband terminal; The emergency broadcast platform is used to receive the alarm information sent by the guardian terminal, and according to the disconnection time and disconnection location, retrieve all monitoring devices within the preset range of the disconnection location after the disconnection time from the monitoring system; Sort the monitoring devices according to their straight-line distances from the disconnection location, and sequentially obtain the monitoring videos captured by each monitoring device; Match the target person in each surveillance video according to the target person's image, and record the time when the target person appears in the surveillance video and the installation location of the corresponding surveillance equipment; The installation locations are sorted according to the time of appearance to generate a movement trajectory, the movement trajectory is sent to the guardian terminal in real time, and the broadcasting equipment on the movement trajectory is controlled to broadcast.

[0026] In some specific implementations, the guardian terminal is used to monitor the connection status between the guardian terminal and the associated wristband terminal in real time, and when it is detected that the connection between the guardian terminal and the associated wristband terminal is disconnected, the disconnection time and disconnection position at this time are recorded and a vibration reminder is issued, and it is determined whether the guardian terminal and the associated wristband terminal can be reconnected within the first preset waiting time. If they can be reconnected, the recorded disconnection time and disconnection position are deleted and the vibration reminder is cancelled. If they cannot be reconnected, the alarm information is uploaded; The associated bracelet terminal is used to issue a vibration reminder when it detects that the connection with the associated bracelet terminal is disconnected. When the connection is restored within the first preset waiting time, the vibration reminder is cancelled. When the connection is not restored within the first preset waiting time, the associated bracelet terminal immediately plays the voice reminder received in advance from the guardian terminal.

[0027] Example 2 like Figure 2 As shown, this embodiment is based on the system of embodiment 1 and provides a scenic area management method based on an emergency broadcast platform. The emergency broadcast platform performs the following steps: S1. Receive the alarm information sent by the guardian terminal, where the alarm information includes the disconnection time and location when the guardian terminal is disconnected from the associated wristband terminal, and an image of the target person wearing the associated wristband terminal taken when the guardian terminal is bound to the associated wristband terminal; images including the face and body parts can be taken, so that the face image can be used for matching and searching, and the whole body image can be used to track fuzzy matching.

[0028] Specifically, the process of uploading the alarm information in step S1 is as follows: The guardian terminal monitors the connection status between the guardian terminal and the associated wristband terminal in real time. When it is detected that the connection between the guardian terminal and the associated wristband terminal is disconnected, the disconnection time and disconnection position are recorded at this time, and it is determined whether the guardian terminal and the associated wristband terminal can be reconnected within the first preset waiting time. If they can be reconnected, the recorded disconnection time and disconnection position are deleted. If they cannot be reconnected, the alarm information is uploaded.

[0029] The scenic area is large and has a large flow of people. The connection between the guardian terminal and the associated bracelet terminal is easy to disconnect and reconnect. Therefore, a certain waiting time can be set. If the connection is reconnected within the waiting time, it may mean that the child has run away from the guardian's sight or the network connection is not good.

[0030] S2. According to the disconnection time and disconnection location, retrieve from the monitoring system all monitoring devices within a preset range of the disconnection location after the disconnection time; S3, sorting the monitoring devices according to the straight-line distance from the disconnection location, and sequentially acquiring the monitoring videos captured by each monitoring device; The specific process of step S3 is: S31, obtaining the installation positions of monitoring devices within a preset range of the disconnection position, and calculating the straight-line distance between each monitoring device and the disconnection position; S32, obtaining a preset scenic spot tour route, classifying each monitoring device according to the scenic spot tour route, and obtaining the monitoring video of each monitoring device after the disconnection time; S33, storing all monitoring devices on the same scenic spot tour route into an analysis list according to the straight-line distance from near to far, to obtain a plurality of analysis lists.

[0031] like Figure 3 As shown, in this embodiment, the scenic area tour route can be divided according to each branch road. Generally, each tour route is relatively long. The present application starts searching when a disconnection is detected, and the response speed is relatively fast. Therefore, generally speaking, the target person has a greater chance of moving along a certain road (tour route) after being disconnected. Therefore, the monitoring equipment can be divided according to the scenic area tour route. In this way, when the target person is found on a scenic area tour route, it is very likely that the target person will move along the route. The target person's movement trajectory can be known by simply checking the monitoring equipment along the route.

[0032] S4. Match the target person in each surveillance video according to the target person image, and record the time when the target person appears in the surveillance video and the installation location of the corresponding surveillance device; The specific process of step S4 is: S41, first obtaining, according to the disconnection location, monitoring videos of all monitoring devices within a first distance range from the disconnection location at the disconnection time point; The first distance range may be a circle of monitoring devices closest to the disconnection location, for example, all monitoring devices within 500 meters. If the monitoring devices within the first range can see the target person, it means that the target person is very likely to move along the route where the monitoring device is located. Therefore, all monitoring devices on the corresponding route can be screened out, so that the analysis of other routes can be omitted, and the routes with higher possibilities can be analyzed first; S42, matching the target person image with the image frame captured from the surveillance video. If the surveillance video can match the target person, the matched target person is marked in the surveillance video, and the position of the target person is continuously tracked; If the target person can be matched in the surveillance video, the target person's movement direction can be analyzed first, and the target person's movement direction can be roughly inferred to inform the guardian to find the direction, and the target person's movement direction can be obtained and notified to the guardian terminal.

[0033] Specifically, the specific process of analyzing the action direction of the target personnel is as follows: When the target person can be matched in the surveillance video, the starting position of the picture frame corresponding to the target person appearing in the surveillance video and the ending position of the picture frame corresponding to the target person leaving the surveillance video are recorded; According to the coordinates of the starting position and the end position, the direction of the end position relative to the starting position is calculated, and the direction is notified to the guardian terminal as the movement direction of the target person.

[0034] like Figure 4 As shown, assuming that a coordinate system is established with the upper left corner of the image frame as the starting point, the starting position coordinates of the detected target person and the ending position coordinates of any point after the target person moves (which can be when leaving the monitoring range of the surveillance video) are recorded, the relative position relationship between the ending position and the starting position can be calculated, and the moving direction of the target person can be determined (which can be expressed as right, left, lower right, etc.).

[0035] S43, obtaining an analysis list of monitoring devices corresponding to the matched monitoring videos, and obtaining the monitoring videos of each monitoring device in the analysis list in turn; S44, matching the target person in each surveillance video according to the target person image, and recording the time when the target person appears in the surveillance video and the installation location of the corresponding surveillance device.

[0036] When matching in each surveillance video, assume that an analysis list includes surveillance device 1 and surveillance device 2. After analyzing surveillance video 1 sent by the surveillance device, record the time when the target person disappears from surveillance video 1. When calling surveillance video 2 of surveillance device 2, use the disappearance time as the starting point of surveillance video 2 to start the search.

[0037] S5. Sort the installation positions according to the time of appearance to generate a motion track, send the motion track to the guardian terminal in real time, and control the broadcasting device on the motion track to broadcast.

[0038] Specifically, the warning information also includes the name and age of the person wearing the associated wristband terminal. Step S5 also includes the following steps: According to the matching analysis list, the broadcasting devices on the scenic spot tour route corresponding to the analysis list are obtained, the broadcasting information is generated according to the name and age, and the broadcasting information is inserted into each broadcasting device.

[0039] In order to enable both the guardian and the target person to be sensitive to separation events, when it is detected that the connection between the guardian terminal and the associated bracelet terminal is disconnected, both the guardian terminal and the associated bracelet terminal will issue a vibration reminder. When the connection is restored within the first preset waiting time, the vibration reminder will be cancelled. When the connection is not restored within the first preset waiting time, the associated bracelet terminal will immediately play the voice reminder received in advance from the guardian terminal.
