Description

Technical Field

[0001] The present invention relates to the technical field of big data processing, and more specifically to a method and system for tourist safety warning based on positioning information. Background Art

[0002] With the booming development of the tourism industry in China, traveling has become a fashionable consumption mode for people to pursue spiritual satisfaction. Along with the rise of various travel modes such as self-driving tours, self-guided tours, and group tours, and the increasing number of domestic tourists, a series of safety issues have also become the concerns of tourists. For example, when traveling in a group, especially when elderly or children tourists get separated from the group, due to unfamiliarity with the surrounding environment, it is very easy to lead to safety problems. The search work often can only be carried out by asking the scenic spot service staff to broadcast the search, with low efficiency. Or, for tourists on outdoor tours, their personal safety may also be threatened due to unexpected accidents.

[0003] How to detect the safety situation of tourists based on their location information and issue early warnings in a timely manner is a technical problem that needs to be solved. Summary of the Invention

[0004] The technical task of the present invention is to address the above deficiencies and provide a method and system for tourist safety warning based on positioning information to solve the technical problem of how to detect the safety situation of tourists based on their location information and issue early warnings in a timely manner.

[0005] In a first aspect, the present invention discloses a method for tourist safety warning based on positioning information, which is applied to tourists carrying mobile terminals. The mobile terminals are configured with location positioning, message push, map navigation, and location sharing services. The method includes the following steps:

[0006] Collect the real-time location of tourists: For each tourist, based on the authorization of the tourist, collect the real-time location of the tourist through the location positioning service provided by the mobile terminal carried by the tourist.

[0007] Perform safety warning based on the real-time location of tourists: For each tourist, based on the real-time location of the tourist, determine whether the tourist is within a safe distance. Based on whether the tourist is within the safe distance and the duration of stay within the safe distance, send a message to the tourist to determine whether to initiate a warning. If the tourist chooses to initiate a warning or fails to confirm whether to initiate a warning after a predetermined time, push warning information to other members within the group or service points based on the predetermined warning rules.

[0008] Preferably, based on the warning rules, the safety warning is divided into two levels, namely:

[0009] Level 1 warning: The Level 1 warning pushes warning information, including the tourist's current location, to other members of the group and informs them to contact the tourist in a timely manner. If other members of the group believe that assistance from tourist service points is needed, Level 2 warning is activated.

[0010] Level 2 warning: The Level 2 warning is to push warning information, including the tourist's current location and the emergency contact person specified in the basic information, to the service point, and inform the service point to contact the tourist and other members of the group in a timely manner.

[0011] If a tourist fails to confirm whether to activate a Level 1 alert after the scheduled time, the Level 1 alert will be automatically activated, notifying other members of the group to contact the tourist promptly.

[0012] As a preferred approach, for each tourist, a safety alert is issued based on the tourist's real-time location, including the following steps:

[0013] L1. Set a fixed target location, or set a target team member and use the real-time location of the target team member as the target location. Set the safe distance D0 between the tourist and the target location, and set the stay time T0 of the tourist within the predetermined distance range.

[0014] L2. Calculate the straight-line distance D1 between the tourist's real-time location and the target location. If the distance D1 is less than the safe distance D0, the tourist is within the safe range and proceed to step L3. Otherwise, the tourist is outside the safe range and proceed to step L5.

[0015] L3. Calculate the duration T1 of the tourist's stay in the same location or safe area, and determine whether the duration T1 exceeds the duration T0. If not, proceed to step L4; if so, proceed to step L5.

[0016] L4. Continue browsing;

[0017] L5. Send a message to the tourist asking whether to activate the warning to notify other members of the group. If the tourist chooses to activate the warning, proceed to step L6. If the tourist chooses not to activate the warning, proceed to step L4. You can also choose whether to adjust the set safe distance D0. If the tourist does not confirm whether to activate the warning after the scheduled time, proceed to step L6.

[0018] L6. Activate Level 1 alert and push the alert information to other team members. Other team members confirm whether the tourist has any safety issues. If team members believe that assistance from nearby service points is needed, proceed to step L7; otherwise, proceed to step L8, or proceed to step L4. The tourist continues the tour, and the Level 1 alert is canceled.

[0019] L7. Activate Level 2 warning and push warning information to nearby service points. The warning information includes the tourist's current location and emergency contact information, and inform the service points to contact the tourist or other members of the group in a timely manner.

[0020] L8. Tourists can meet up with other members of their team based on location sharing and map navigation services provided by their mobile devices.

[0021] As a preferred method, the following should be performed before collecting the real-time location of tourists:

[0022] Each tourist is assigned a number, and a basic information table for the team is built based on each tourist's tourist number and basic tourist information;

[0023] Construct a team location information table, which is used to store the visitor ID and real-time location of each visitor;

[0024] For each tourist, after collecting the tourist's real-time location, the real-time location is stored in the team location information table;

[0025] When the target location is the real-time location of the target team members, the real-time location of the target team members is obtained based on the team location information table, and the straight-line distance D1 between the real-time location of the tourist and the target location is calculated.

[0026] Secondly, the present invention provides a tourist safety early warning system based on location information, configured on a mobile terminal, for implementing tourist safety early warning through the tourist safety early warning method based on location information as described in any of the first aspects, wherein the mobile terminal is configured with location positioning, message push, map navigation, and location sharing services, and the system includes:

[0036] L3. Calculate the duration T1 of the tourist's stay in the same location or safe area, and determine whether the duration T1 exceeds the duration T0. If not, proceed to step L4; if so, proceed to step L5.

[0037] L4. Continue browsing;

[0038] L5. Send a message to the tourist asking whether to activate the warning to notify other members of the group. If the tourist chooses to activate the warning, proceed to step L6. If the tourist chooses not to activate the warning, proceed to step L4. You can also choose whether to adjust the set safe distance D0. If the tourist does not confirm whether to activate the warning after the scheduled time, proceed to step L6.

[0039] L6. Activate Level 1 alert and push the alert information to other team members. Other team members confirm whether the tourist has any safety issues. If team members believe that assistance from nearby service points is needed, proceed to step L7; otherwise, proceed to step L8, or proceed to step L4. The tourist continues the tour, and the Level 1 alert is canceled.

[0040] L7. Activate Level 2 warning and push warning information to nearby service points. The warning information includes the tourist's current location and emergency contact information, and inform the service points to contact the tourist or other members of the group in a timely manner.

[0041] L8. Tourists can meet up with other members of their team based on location sharing and map navigation services provided by their mobile devices.

[0042] Preferably, the system further includes a configuration module, which is used to perform the following:

[0043] Each tourist is assigned a number, and a basic information table for the team is built based on each tourist's tourist number and basic tourist information;

[0044] Construct a team location information table, which is used to store the visitor ID and real-time location of each visitor;

[0045] For each tourist, after collecting the tourist's real-time location, the real-time location is stored in the team location information table;

[0046] When the target location is the real-time location of the target team members, the safety warning module performs the following: based on the team location information table, obtain the real-time location of the target team members, and calculate the straight-line distance D1 between the real-time location of the tourist and the target location.

[0047] The tourist safety early warning method and system based on location information of the present invention have the following advantages:

[0048] 1. By utilizing the location data of tourists during their visit, combined with threshold settings such as safe distance, duration of stay at a location, and duration of unconfirmed visits, the system can monitor and issue early warnings for tourist safety in real time, ensuring tourist safety while reducing the possibility of misjudgment.

[0049] 2. Safety alerts are divided into Level 1 and Level 2 alerts. Level 1 alerts only notify members of the tour group. If members of the tour group confirm a serious safety issue, a Level 2 safety alert is issued, notifying nearby tourist service points. This provides different options for different situations, reduces misjudgments, and avoids the waste of public resources due to false alarms. Attached Figure Description

[0053] Figure 2 This is a block diagram illustrating the early warning setting principle in the tourist safety early warning method based on location information in Example 1. Detailed Implementation

[0054] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0055] This invention provides a tourist safety early warning method and system based on location information, which solves the technical problem of how to detect tourist safety status based on tourist location information and issue timely early warnings.

[0056] Example 1:

[0057] This invention provides a tourist safety early warning method based on location information, applicable to tourists carrying mobile terminals equipped with location positioning, message push, map navigation, and location sharing services. The method includes the following steps:

[0058] S100. Collect the real-time location of tourists: For each tourist, based on the tourist's authorization, the real-time location of the tourist is collected through the location positioning service provided by the mobile terminal carried by the tourist.

[0059] S200, Safety alerts based on tourists' real-time location: For each tourist, based on the tourist's real-time location, determine whether the tourist is within a safe distance, and based on whether the tourist is within a safe distance and the length of time the tourist stays within a safe distance, send a message to the tourist to ask whether to activate an alert. If the tourist chooses to activate an alert or does not confirm whether to activate an alert within the scheduled time, the alert information is pushed to other members of the team or service points based on the predetermined alert rules.

[0060] In this embodiment, based on early warning rules, safety early warnings are divided into two levels: Level 1 and Level 2. Level 1 early warning pushes warning information, including the tourist's current location, to other members of the group, informing them to contact the tourist promptly. If other members of the group believe that assistance from a tourist service point is needed, Level 2 early warning is activated. Level 2 early warning pushes information, including the tourist's current location and the emergency contact specified in the basic information, to the service point, informing the service point to contact the tourist and other members of the group promptly. If the tourist fails to confirm whether to activate Level 1 early warning within a predetermined time, Level 1 early warning is automatically activated, notifying other members of the group to contact the tourist promptly.

[0061] In step S200, for each tourist, a safety alert is issued based on the tourist's real-time location, including the following steps:

[0062] L1. Set a fixed target location, or set a target team member and use the real-time location of the target team member as the target location. Set the safe distance D0 between the tourist and the target location, and set the stay time T0 of the tourist within the predetermined distance range.

[0063] L2. Calculate the straight-line distance D1 between the tourist's real-time location and the target location. If the distance D1 is less than the safe distance D0, the tourist is within the safe range and proceed to step L3. Otherwise, the tourist is outside the safe range and proceed to step L5.

[0064] L3. Calculate the duration T1 of the tourist's stay in the same location or safe area, and determine whether the duration T1 exceeds the duration T0. If not, proceed to step L4; if so, proceed to step L5.

[0065] L4. Continue browsing;

[0066] L5. Send a message to the tourist asking whether to activate the warning to notify other members of the group. If the tourist chooses to activate the warning, proceed to step L6. If the tourist chooses not to activate the warning, proceed to step L4. You can also choose whether to adjust the set safe distance D0. If the tourist does not confirm whether to activate the warning after the scheduled time, proceed to step L6.

[0067] L6. Activate Level 1 alert and push the alert information to other team members. Other team members confirm whether the tourist has any safety issues. If team members believe that assistance from nearby service points is needed, proceed to step L7; otherwise, proceed to step L8, or proceed to step L4. The tourist continues the tour, and the Level 1 alert is canceled.

[0068] L7. Activate Level 2 warning and push warning information to nearby service points. The warning information includes the tourist's current location and emergency contact information, and inform the service points to contact the tourist or other members of the group in a timely manner.

[0069] L8. Tourists can meet up with other members of their team based on location sharing and map navigation services provided by their mobile devices.

[0070] Before collecting tourists' real-time locations during implementation, the following steps should be taken:

[0071] (1) Assign a number to each tourist and construct a team basic information table based on each tourist's tourist number and basic tourist information;

[0072] (2) Construct a team location information table, which is used to store the visitor number and real-time location of each visitor.

[0073] For each tourist, after collecting the tourist's real-time location, the real-time location is stored in the team location information table.

[0074] In step S200, when the target location is the real-time location of the target team members, the real-time location of the target team members is obtained based on the team location information table, and the straight-line distance D1 between the tourist's real-time location and the target location is calculated.

[0075] Based on the above method, a specific example is given, which includes the following three steps.

[0076] The first step involves the user inputting information about other team members, constructing a basic information table for team members, and numbering team members according to the sequence 1, 2, 3, ..., i, ..., n. The team number data is then stored in the basic information table, and a set of team member geographic locations (G1, G2, G3, ..., G...) is constructed. i ,……G n ), G i This indicates the current geographical location of the member with ID i. The team location information table stores the set of geographical locations of the team members. The team location table is used to store the ID and real-time location of the team members.

[0077] With the consent of the tourists, the mobile terminal uses wireless network communication technology and GPS positioning technology to obtain the tourists' real-time location information and then stores the tourists' location information in the group location information table.

[0078] The second step involves real-time assessment of the tourist's location to determine if they have become separated from the group or encountered other unforeseen circumstances. First, the tourist sets a specific location or a target member within the group as the distance measurement target, and a safe distance D0 is set. The straight-line distance D between the tourist's current location and the set location is then calculated in real-time.i If the straight-line distance exceeds the safe distance, i.e., D i If the distance is ≥D0, a message will be sent to the tourist to confirm whether to activate the alert. If the tourist confirms that the alert is canceled, the tourist can continue their tour and can choose whether to adjust the set safe distance D0. If the tourist confirms that the alert is activated or does not confirm within the specified time, it is determined that the tourist may have encountered a safety issue, and an alert will be pushed to other members of the group to help confirm the tourist's current safety status.

[0079] A threshold T0 is set for the duration of a visitor's stay within a small area. Based on this, the duration T1 of the visitor's stay within a small area (e.g., within 2-3 meters) at their current location is calculated in real time. If the stay duration exceeds the threshold (T1 ≥ T0), a message is sent to the visitor to confirm whether to activate the alert. If the visitor confirms that the alert is canceled, the visitor can proceed with their tour as normal. If the visitor chooses to activate the alert or fails to confirm after the specified duration, an alert is sent to other members of the group.

[0080] The third step involves tourists confirming whether to activate the alert based on the actual situation. To avoid wasting public resources due to false alarms, while still reminding other members of the group to pay attention to the tourists' safety, this embodiment divides the safety alert into two levels. The first-level alert pushes the tourist's current location information to other members of the group and informs them to contact the tourist immediately. If a group member believes that assistance from a tourist service point is needed to resolve the current problem, a second-level alert is activated. After the second-level alert is activated, alert information is pushed to nearby service points, including the tourist's current location, emergency contact information, etc., and the service point is informed to contact the tourist or other members of the group immediately. In addition, to prevent situations where tourists cannot confirm the activation of the safety alert themselves, if the tourist fails to confirm within a specified time, the first-level safety alert is automatically activated, notifying other tourists in the group to contact the tourist immediately to confirm their current safety. After activating the alert, tourists can use location sharing, map navigation, and other functions to reunite with other members of the group.

[0081] Example 2:

[0082] This invention discloses a tourist safety early warning system based on location information, configured on a mobile terminal, including a data acquisition module and a safety early warning module, used to implement tourist safety early warning through the method disclosed in Embodiment 1. The mobile terminal is equipped with location positioning, message push, map navigation, and location sharing services.

[0083] The data acquisition module is used to collect the real-time location of tourists as follows: for each tourist, based on the tourist's authorization, the real-time location of the tourist is collected through the location positioning service provided by the mobile terminal carried by the tourist.

[0084] The safety alert module is used to perform the following safety alerts based on the real-time location of tourists: For each tourist, based on the tourist's real-time location, it determines whether the tourist is within the safe distance, and based on whether the tourist is within the safe distance and the length of time the tourist stays within the safe distance, it sends a message to the tourist to ask whether to activate the alert. If the tourist chooses to activate the alert or does not confirm whether to activate the alert within the predetermined time, the alert information is pushed to other members of the team or service points based on the predetermined alert rules.

[0085] In this embodiment, based on early warning rules, safety early warnings are divided into two levels: Level 1 and Level 2. Level 1 early warning pushes warning information, including the tourist's current location, to other members of the group and instructs them to contact the tourist promptly. If other members of the group believe that assistance from a tourist service point is needed, Level 2 early warning is activated. Level 2 early warning pushes the tourist's current location and information such as the emergency contact person specified in the basic information to the service point and instructs the service point to contact the tourist and other members of the group promptly. If the tourist fails to confirm whether to activate Level 1 early warning within the predetermined time, Level 1 early warning is automatically activated, notifying other members of the group to contact the tourist promptly.

[0086] For each tourist, the security alert module is used to perform the following security alerts based on the tourist's real-time location:

[0087] L1. Set a fixed target location, or set a target team member and use the real-time location of the target team member as the target location. Set the safe distance D0 between the tourist and the target location, and set the stay time T0 of the tourist within the predetermined distance range.

[0088] L2. Calculate the straight-line distance D1 between the tourist's real-time location and the target location. If the distance D1 is less than the safe distance D0, the tourist is within the safe range and proceed to step L3. Otherwise, the tourist is outside the safe range and proceed to step L5.

[0089] L3. Calculate the duration T1 of the tourist's stay in the same location or safe area, and determine whether the duration T1 exceeds the duration T0. If not, proceed to step L4; if so, proceed to step L5.

[0090] L4. Continue browsing;

[0091] L5. Send a message to the tourist asking whether to activate the warning to notify other members of the group. If the tourist chooses to activate the warning, proceed to step L6. If the tourist chooses not to activate the warning, proceed to step L4. You can also choose whether to adjust the set safe distance D0. If the tourist does not confirm whether to activate the warning after the scheduled time, proceed to step L6.

[0092] L6. Activate Level 1 alert and push the alert information to other team members. Other team members confirm whether the tourist has any safety issues. If team members believe that assistance from nearby service points is needed, proceed to step L7; otherwise, proceed to step L8, or proceed to step L4. The tourist continues the tour, and the Level 1 alert is canceled.

[0093] L7. Activate Level 2 warning and push warning information to nearby service points. The warning information includes the tourist's current location and emergency contact information, and inform the service points to contact the tourist or other members of the group in a timely manner.

[0094] L8. Tourists can meet up with other members of their team based on location sharing and map navigation services provided by their mobile devices.

[0095] As an improvement, the system in this embodiment also includes a configuration module, which is used to perform the following:

[0096] (1) Assign a number to each tourist and construct a team basic information table based on each tourist's tourist number and basic tourist information;

[0097] (2) Construct a team location information table, which is used to store the visitor number and real-time location of each visitor.

[0098] For each tourist, the data acquisition module performs the following: after collecting the tourist's real-time location, it stores the real-time location in the team location information table.

[0099] When the target location is the real-time location of the target team members, the safety warning module performs the following: based on the team location information table, obtain the real-time location of the target team members, and calculate the straight-line distance D1 between the real-time location of the tourist and the target location.

[0100] The system in this embodiment is installed as an APP on a mobile terminal. The APP includes an APP client and a data acquisition module and a security warning module that work with the client. The following three steps are performed through the APP.

[0101] The first step involves using a mobile app client. Users input information about other team members through the app, creating a basic information table for team members. Team members are numbered 1, 2, 3, ..., i, ..., n, and the team number data is stored in the basic information table. This creates a set of team member geographic locations (G1, G2, G3, ..., G...). i ,……G n ), G i This indicates the current geographical location of the member with ID i. The team location information table stores the set of geographical locations of the team members. The team location table is used to store the ID and real-time location of the team members.

[0102] With the consent of the tourists, the mobile terminal uses wireless network communication technology and GPS positioning technology to obtain the tourists' real-time location information and then stores the tourists' location information in the group location information table.

[0103] The second step involves real-time assessment of tourists' locations to determine if they have become separated from the group or if any other unforeseen circumstances have occurred. First, tourists set a specific location or a target member within their group as the distance measurement target on their mobile app, and set a safe distance D0. The app then uses a safety alert module to calculate the straight-line distance D between the tourist's current location and the set location in real time. i If the straight-line distance exceeds the safe distance, i.e., D i If the distance is ≥D0, the app client will send a message to the tourist through the safety alert module to confirm whether to activate the alert. If the tourist confirms that the alert is canceled, the tourist can continue their tour as normal and can choose whether to adjust the set safety distance D0. If the tourist confirms that the alert is activated or fails to confirm within the specified time, the system will determine that the tourist may have encountered a safety issue and will use the message push module to notify other members of the group to help confirm the tourist's current safety status.

[0104] The safety alert module sets a threshold T0 for the duration of a visitor's stay within a small area. Based on this, the app client will calculate in real time the duration T1 of the visitor's stay within a small area (e.g., within 2-3 meters) of their current location. If the stay duration exceeds the threshold (T1 ≥ T0), the app client will send a message to the visitor to confirm whether to activate the alert. If the visitor confirms that the alert is canceled, the visitor can proceed with their tour as normal. If the visitor chooses to activate the alert or fails to confirm within the specified time, the app client will activate the safety alert and notify other members of the group via push notification.

[0105] The third step involves tourists confirming whether to activate the alert based on the actual situation. To avoid wasting public resources due to false alarms, while simultaneously reminding other members of the group to pay attention to the tourists' safety, this invention divides the safety alert into two levels. Level 1 alerts push the tourist's current location information to other members of the group and inform them to contact the tourist immediately. If group members believe that assistance from tourist service points is needed to resolve the current issue, a Level 2 alert is activated. Upon activation of the Level 2 alert, the system notifies the scenic area service point, pushing the tourist's current location, emergency contact information, etc., and instructing the service point to contact the tourist or other members of the group immediately. Furthermore, to prevent situations where tourists cannot confirm the activation of the safety alert themselves, the system will automatically activate the Level 1 safety alert if the tourist fails to confirm within a specified time, notifying other tourists in the group to contact the tourist immediately to confirm their safety. After activating the alert, tourists can use location sharing, map navigation, and other functions to reunite with other members of the group.

[0106] The present invention has been shown and described in detail above with reference to the accompanying drawings and preferred embodiments. However, the present invention is not limited to these disclosed embodiments. Based on the above embodiments, those skilled in the art will know that more embodiments of the present invention can be obtained by combining the means in the different embodiments described above, and these embodiments are also within the protection scope of the present invention.
