Description

Technical Field

[0001] This invention relates to the field of autonomous driving communication technology, and in particular to a method and system for quickly calling accompanying personnel using NFC in an autonomous driving scenario. Background Technology

[0002] During train operation, the reporting of the location of onboard personnel plays a crucial role in vehicle operation and management. Dispatchers need to accurately grasp the real-time location of onboard personnel so that, in the event of emergencies or urgent situations, the dispatch center can promptly dispatch rescue forces or carry out other necessary emergency measures based on the location information of the onboard personnel. This also helps the dispatch center to more accurately understand the distribution of vehicles and onboard personnel, thereby enabling more rational task allocation.

[0003] However, existing dispatching systems often rely on onboard personnel to proactively report their location information. This not only leads to untimely information updates but also risks omissions or errors in location recording due to human factors (such as forgetfulness or operational mistakes). For example, if onboard personnel forget to update their location while the train is in motion due to other tasks, the dispatcher will be unable to accurately determine their location, potentially affecting the accurate transmission of emergency rescue or dispatch instructions. Furthermore, dispatchers themselves may also make recording errors due to heavy workloads or distractions, further exacerbating the problem of inaccurate information.

[0004] Besides location reporting, real-time communication between dispatchers and onboard personnel is crucial during train operations. However, the current dispatching system's individual and group call methods both suffer from slow response times. For individual calls, dispatchers need to query the onboard personnel's calling numbers from a vast database, resulting in a slow call setup process. Even in the fastest-running scenario, it takes about 10 seconds to initiate a call, which is not only time-consuming but can also fail due to changes in the calling numbers or inaccurate records. While group calls can notify multiple onboard personnel at once, dispatchers must manually create a temporary call group and add the calling numbers of all personnel to be called to that group. Similar to individual calls, querying the onboard personnel's calling numbers is slow, creating a temporary call group requires numerous interface operations, and the call setup time is also slow, taking at least 15 seconds in the fastest-running scenario. In emergencies, this delay can prevent the timely transmission of critical instructions, impacting the efficiency of emergency response.

[0005] Furthermore, the high mobility of passengers on trains during operation, with frequent boarding and alighting, necessitates that the dispatching system be able to update the communication group members in real time. However, existing dispatching systems often fail to do this. Once a group call is established, newly added passengers are difficult to add to the communication group quickly, and passengers alighting cannot be removed from the group in a timely manner. This not only wastes communication resources but may also affect the clarity and accuracy of dispatching instructions due to unnecessary communication interference. In emergencies, failure to promptly include key personnel in the communication group can lead to poor information transmission and delays in rescue efforts. Summary of the Invention

[0006] To address the problems existing in the prior art, this invention provides a method for quickly calling accompanying personnel using NFC in an autonomous driving scenario, wherein at least one NFC tag is pre-installed on the train; the method includes:

[0007] Step S1: When boarding the vehicle, the passenger touches the NFC tag with a handheld device to send a location binding request to the connected dispatch server. The location binding request includes the unique identifier of the NFC tag and the calling number of the handheld device.

[0008] Step S2: The dispatch server obtains the corresponding real-time train location based on the unique identifier as the real-time location of the accompanying personnel, and sends the real-time location of the personnel and the corresponding call number to the connected dispatch console.

[0009] Step S3: The dispatch console automatically creates a temporary call group based on the real-time location of the person and the corresponding call number, so that the dispatcher can quickly make a call to the corresponding accompanying person through the temporary call group;

[0010] The calling numbers of the handheld radios held by the various personnel on the same train are located in the same temporary call group.

[0011] Preferably, the scheduling server stores a correspondence table between multiple unique identifiers and the real-time train positions associated with them; step S2 includes:

[0012] The scheduling server matches the corresponding relationship table to determine whether the corresponding unique identifier exists in the relationship table:

[0013] If so, a location binding success notification is sent to the handheld terminal, and the real-time train location associated with the unique identifier and the corresponding call number are sent to the dispatch console;

[0014] If not, a location binding failure message is sent to the handheld device, and then the process exits.

[0015] Preferably, the NFC tag stores train information of the train it is on; the location binding request also includes the train information;

[0016] The dispatch server simultaneously sends the train information, the real-time location of the personnel, and the corresponding call number to the dispatch console. The dispatch console adds the call numbers of the handheld radios held by the accompanying personnel on the same train to the same temporary call group based on the train information.

[0017] Preferably, it also includes a binding cancellation process:

[0018] Step A1: When the accompanying personnel get off the vehicle, they send an unbinding request to the dispatch server via the handheld radio.

[0019] Step A2: The scheduling server executes the unbinding request and determines whether the unbinding was successful.

[0020] If so, a notification of successful unbinding is sent to the handheld device and the dispatch console, and then proceeds to step A3;

[0021] If not, a cancellation failure message is sent to the handheld device, and then the process exits.

[0022] Step A4: The dispatch console removes the corresponding accompanying personnel from the temporary call group based on the successful cancellation message.

[0023] Preferably, after performing step A4, the method further includes:

[0024] When the dispatch console determines that all accompanying personnel in the temporary call group have successfully unbound their accounts, it deletes the temporary call group.

[0025] Preferably, the dispatch console provides a dispatch interface for displaying train icons for all trains, and when there are accompanying personnel on a train, the corresponding train icon is displayed separately.

[0026] Preferably, when the dispatcher selects the train icon containing the accompanying personnel through the dispatching interface, the method further includes:

[0027] The dispatch console generates a list of the personnel accompanying the train and displays it on the dispatch interface, so that the dispatcher can quickly initiate dispatch operations.

[0028] This invention also provides a system for quickly calling accompanying personnel using NFC in autonomous driving scenarios, comprising:

[0029] NFC tags are installed on the train;

[0030] A handheld device is provided for use by accompanying personnel. When the accompanying personnel touch the NFC tag through the handheld device upon boarding the vehicle, a location binding request is sent. The location binding request includes the unique identifier of the NFC tag and the calling number of the handheld device.

[0031] The dispatch server is connected to the handheld radio and the dispatch console respectively. It is used to receive the location binding request, then obtain the corresponding real-time train location based on the unique identifier as the real-time location of the accompanying personnel, and send the real-time location of the personnel and the corresponding call number to the dispatch console.

[0032] The dispatch console is used to automatically create a temporary call group based on the real-time location of the person and the corresponding call number, so that the dispatcher can quickly make a call to the corresponding accompanying person through the temporary call group;

[0033] The calling numbers of the handheld radios held by the various personnel on the same train are located in the same temporary call group.

[0034] Preferably, the scheduling server includes:

[0035] The storage module is used to store a table showing the correspondence between multiple unique identifiers and the real-time train positions associated with the trains.

[0036] The matching module, connected to the storage module, is used to match the unique identifier with the corresponding relationship table, and when the corresponding unique identifier is matched in the corresponding relationship table, send a location binding success prompt to the handheld terminal, and send the real-time train location associated with the unique identifier and the corresponding call number to the dispatch console;

[0037] And when no matching unique identifier is found, a location binding failure message is sent to the handheld device.

[0038] Preferably, the accompanying personnel send an unbinding request to the dispatch server via the handheld radio when they get off the vehicle;

[0039] The scheduling server also includes a cancellation execution module, which executes the unbinding request and sends a successful unbinding prompt to the handheld terminal and the scheduling terminal when the unbinding is successful, and sends a failed unbinding prompt to the handheld terminal when the unbinding is unsuccessful.

[0040] The dispatch console also includes a deletion module, used to delete the corresponding accompanying personnel from the temporary call group based on the successful cancellation message.

[0041] The above technical solution has the following advantages or beneficial effects:

[0042] 1) Passengers can bind their trains by touching NFC, which will not result in binding errors and is simple and quick to operate; at the same time, the dispatch console can automatically and in real time obtain the location information of the passengers.

[0043] 2) The dispatch console can automatically create temporary call groups without errors or omissions, greatly simplifying the complexity of dispatching and improving the accuracy of dispatching operations; moreover, the dispatching process is highly automated, with fast dispatching response speed and rich dispatching methods, making it suitable for autonomous driving scenarios.

[0046] Figure 3 This is a schematic diagram of a system for quickly calling accompanying personnel using NFC in a driverless scenario, as a preferred embodiment of the present invention. Detailed Implementation

[0047] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment; other embodiments that conform to the spirit of the present invention may also fall within the scope of the present invention.

[0048] In a preferred embodiment of the present invention, based on the aforementioned problems existing in the prior art, a method for quickly calling accompanying personnel using NFC in an autonomous driving scenario is provided, wherein at least one NFC tag is pre-installed on the train; such as Figure 1 As shown, the method includes:

[0049] Step S1: When boarding the vehicle, the passenger touches the NFC tag with a handheld device to send a location binding request to the connected dispatch server. The location binding request includes the unique identifier of the NFC tag and the call number of the handheld device.

[0050] Step S2: The dispatch server obtains the corresponding real-time train location based on the unique identifier as the real-time location of the accompanying personnel, and sends the personnel's real-time location and corresponding call number to the connected dispatch console.

[0051] Step S3: The dispatch console automatically creates a temporary call group based on the real-time location of the personnel and the corresponding call number, so that the dispatcher can quickly make a call to the corresponding accompanying personnel through the temporary call group;

[0052] The call numbers of the handheld radios held by the passengers on the same train are in the same temporary call group.

[0053] Specifically, in this embodiment, the aforementioned NFC tags can be placed at any location on the train as needed, such as where passengers board and alight, or one tag can be placed every few carriages, or one tag can be placed in each carriage. Depending on the placement location, the real-time location of the passengers can be subdivided in different ways. For example, if only one NFC tag is placed on the train, the passenger's real-time location is the same as the real-time train location. If NFC tags are placed in multiple carriages of the train, the passenger's real-time location can be further pinpointed to the specific carriage based on the real-time train location. The carriage information can be stored in the NFC tag, allowing passengers to access the stored carriage information when they touch the NFC tag with a handheld device. This information is then reported to the dispatch server, which in turn sends it to the dispatch console, enabling dispatchers to promptly track the real-time location of each passenger. The handheld device and the NFC tag communicate via NFC near-field communication, while the handheld device and the dispatch server establish a wireless transmission channel via a wireless network.

[0054] Furthermore, the handheld device of the accompanying personnel is preferably equipped with a positioning APP. After boarding the train, the personnel can first open the positioning APP, and then touch the NFC tag on the train with the handheld device. The positioning APP will automatically send a location binding request to the dispatch server of the control center. This location binding request includes at least the unique identifier of the corresponding NFC tag and the calling number of the handheld device. Correspondingly, the dispatch server stores a correspondence table between multiple unique identifiers and the real-time train locations associated with them; step S2 includes:

[0055] The scheduling server matches the corresponding relationship table to determine if a unique identifier exists in the table:

[0056] If so, a location binding success notification will be sent to the handheld radio, and the real-time train location associated with the unique identifier and the corresponding call number will be sent to the dispatch console;

[0057] If not, a location binding failure message will be sent to the handheld device, and then the process will exit.

[0058] Specifically, the aforementioned dispatch server interfaces with the train signaling system, enabling it to promptly obtain real-time train locations and update the corresponding relationship table accordingly. The real-time train location can be the track number currently in which the train is traveling. Since the latitude and longitude corresponding to the track number are fixed and stored, the track number can be used to represent the real-time train location. Upon receiving a unique identifier, the dispatch server first performs a location match in the relationship table. If a match is successful (i.e., a corresponding unique identifier exists in the relationship table), the handheld radio sends a location binding success notification and sends the real-time train location associated with the unique identifier and the corresponding calling number to the dispatch console. This real-time train location is the real-time location of the accompanying personnel, allowing the dispatch console to accurately track their real-time location. Subsequent updates to the personnel's real-time location only require automatic updates based on the unique identifier's binding relationship, eliminating the need for any action from the accompanying personnel or dispatchers. This effectively prevents accompanying personnel from missing or reporting their locations, or dispatchers from missing or incorrectly recording the accompanying personnel's locations.

[0059] In a preferred embodiment of the present invention, the NFC tag stores train information of the train it is on; the location binding request also includes train information.

[0060] The dispatch server simultaneously sends train information, personnel's real-time location, and corresponding call numbers to the dispatch console. The dispatch console then adds the call numbers of the handheld radios held by the personnel on the same train to the same temporary call group based on the train information.

[0061] Specifically, in this embodiment, the dispatch console automatically creates temporary call groups, eliminating the need for dispatchers to manually select or enter the call numbers of passengers on the train when group calls or video group calls are required. Dispatchers only need to select the temporary call group to initiate the call, which is convenient, fast, and avoids errors. When a new passenger binds to the train, i.e., initiates a location binding request, the dispatch console can immediately and automatically update the members in the temporary call group according to the binding relationship. It is understood that if other personnel are on the train, such as the driver, the driver can also be added to the temporary call group simultaneously; this is not limited here and can be selected according to needs.

[0062] In a preferred embodiment of the present invention, such as Figure 2 As shown, it also includes a binding cancellation process:

[0063] Step A1: When the passenger gets off the vehicle, they send a request to the dispatch server to unbind the passenger via a handheld radio.

[0064] Step A2: The scheduling server executes the unbinding request and determines whether the unbinding was successful.

[0065] If so, send a notification of successful unbinding to the handheld radio and the dispatch console, and then proceed to step A3;

[0066] If not, a message indicating unbinding failure will be sent to the handheld device, and then the process will exit.

[0067] In step A3, the dispatch console removes the corresponding accompanying personnel from the temporary call group based on the successful cancellation notification.

[0068] Specifically, in this embodiment, when the accompanying personnel get off the vehicle, they can log in to the positioning APP on the handheld device and click to unbind to send a unbinding request to the dispatch server. When the unbinding is successful, the handheld device displays that the unbinding was successful, and the dispatch console removes the accompanying personnel from the temporary call group to update the temporary call group in real time, effectively solving the technical problem that the call group members cannot be updated in a timely manner after the accompanying personnel get off the vehicle.

[0069] In a preferred embodiment of the present invention, after performing step A3, the method further includes:

[0070] Once the dispatch console determines that all accompanying personnel in the temporary call group have successfully unbound their accounts, it will delete the temporary call group.

[0071] Specifically, if all accompanying personnel successfully unbind, it means there are no accompanying personnel on the train. At this time, the dispatcher will automatically delete the temporary communication group for that train to avoid misleading the dispatchers.

[0072] In a preferred embodiment of the present invention, a dispatching interface is provided on the dispatching console to display train icons for all trains, and when there are passengers on the train, the corresponding train icons are displayed separately.

[0073] In a preferred embodiment of the present invention, when the dispatcher selects a train icon with accompanying personnel through the dispatching interface, the method further includes:

[0074] The dispatch console generates a list of the personnel accompanying the corresponding train and displays it on the dispatch interface, allowing dispatchers to quickly initiate dispatch operations.

[0075] Specifically, in this embodiment, the aforementioned distinction is preferably displayed in a prominent color to indicate to the dispatcher that there are accompanying personnel on the corresponding train. The dispatcher can click the corresponding train icon to view the list of accompanying personnel and dispatch function buttons such as individual calls, video calls, SMS, and MMS. By clicking different function buttons, the dispatcher can quickly initiate corresponding services to the accompanying personnel, thereby quickly realizing various dispatch services such as group calls, individual calls, video group calls, video individual calls, SMS, and MMS to the accompanying personnel. When initiating a group call, the dispatch console will automatically create a temporary call group and automatically add the train's accompanying personnel to the call group. When the dispatcher initiates a call, the accompanying personnel can answer the call without manually switching groups. When there are no accompanying personnel on the train and the temporary call group is deleted, the corresponding train icon returns to its normal display.

[0076] In summary, this invention supports temporary binding between the onboard personnel's handheld device and the train. The onboard personnel can bind the train by touching NFC or unbind the relationship through the APP without any binding errors. In contrast, other methods that use wireless cell location or GPS location information to bind the train result in binding misalignment due to significant location errors. The onboard personnel's location binding and unbinding operations are simple and quick. The dispatch console can automatically and in real time obtain the onboard personnel's location information.

[0077] The dispatch console can automatically create temporary call groups, automatically add and delete members within the groups, and automatically delete call groups. There will be no errors or omissions when adding or deleting members in the call groups, which greatly simplifies the complexity of dispatching and improves the accuracy of dispatching operations. The dispatching process is highly automated, the dispatching response speed is fast, and the dispatching methods are rich.

[0078] The prominent prompts on the dispatch console enable dispatchers to quickly locate passengers on board and initiate cluster services. Passengers do not need the assistance of dispatchers or drivers, nor do they need to operate any other professional equipment. They can simply use a handheld device to touch an NFC tag. The tag can be unbound after disembarking, making it suitable for use in unmanned train scenarios.

[0079] This invention also provides a system for quickly calling accompanying personnel using NFC in autonomous driving scenarios, such as... Figure 3 As shown, it includes:

[0080] NFC tag 1, installed on the train;

[0081] Handheld device 2 is used for accompanying personnel to hold, and when the accompanying personnel touch NFC tag 1 through the handheld device when boarding the vehicle, a location binding request is sent. The location binding request includes the unique identifier of NFC tag 1 and the calling number of handheld device 2.

[0082] The dispatch server 3 is connected to the handheld radio 2 and the dispatch console 4 respectively. It is used to receive location binding requests, and then obtain the corresponding real-time train location based on the unique identifier as the real-time location of the accompanying personnel, and send the real-time location of the personnel and the corresponding call number to the dispatch console 4.

[0083] The dispatch console 4 is used to automatically create temporary call groups based on the real-time location of personnel and the corresponding call numbers, so that dispatchers can quickly make calls to the corresponding accompanying personnel through the temporary call groups;

[0084] The call numbers of the handheld radios held by the passengers on the same train are in the same temporary call group.

[0085] In a preferred embodiment of the present invention, the scheduling server 3 includes:

[0086] Storage module 31 is used to store a table of correspondences between multiple unique identifiers and the real-time train locations of associated trains;

[0087] The matching module 32 is connected to the storage module 31. It is used to match the unique identifier with the corresponding relationship table. When the corresponding unique identifier is matched in the corresponding relationship table, it sends a location binding success prompt to the handheld terminal 2 and sends the real-time train location associated with the unique identifier and the corresponding call number to the dispatching terminal 4.

[0088] And when no matching unique identifier is found, a location binding failure message is sent to handheld station 2.

[0089] In a preferred embodiment of the present invention, when the passenger gets off the vehicle, he / she sends a cancellation request to the dispatch server 3 via a handheld radio 2;

[0090] The dispatch server 3 also includes a cancellation execution module 33, which is used to execute the unbinding request, and send a successful unbinding prompt to the handheld station 2 and the dispatch station 4 when the unbinding is successful, and send a failed unbinding prompt to the handheld station 2 when the unbinding is unsuccessful.

[0091] The dispatch console 4 also includes a deletion module 41, which is used to delete the corresponding accompanying personnel from the temporary call group based on the successful cancellation prompt.

[0092] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention.
