Description

Technical Field

[0001] This application relates to the technical field of rail transit, and in particular, to a communication method, related devices, and a storage medium. Background Art

[0002] With the progress of technology, driverless technology has begun to be introduced into rail transit. Taking subway trains as an example, after the subway enters the driverless stage, there is no driver on the subway train, but for the safety of passengers, on-board personnel are generally arranged. If a passenger presses an alarm device, the alarm device can be connected to the dispatching hall and communicate with the dispatcher. At this time, the dispatcher will coordinate the on-board personnel on the train to carry out emergency handling.

[0003] However, under driverless operation, the on-board personnel may board the train randomly and have no fixed relationship with the train. The dispatcher needs to first query which on-board personnel to contact and then notify the on-board personnel to carry out emergency handling. Therefore, when a passenger presses the alarm device, it is impossible to immediately establish contact with the on-board personnel, and the on-board personnel need to wait for the dispatcher's notice to carry out emergency disposal, unable to respond immediately, which reduces the response efficiency to emergencies.

[0004] Moreover, although the on-board personnel are equipped with communication terminals, they cannot directly participate in the alarm call of the passengers to obtain information, and all information is notified by the dispatcher, resulting in the problem of information lag. Summary of the Invention

[0005] This application provides a communication method, related devices, and a storage medium, aiming to improve the response efficiency of on-board personnel to alarm situations and avoid the problem of information lag.

[0059] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and appended claims of the present application, the singular forms "a", "an", "the", "above-mentioned", "said", "this" are also intended to include expressions such as "one or more", unless there is a clear indication to the contrary in the context. It should also be understood that in the embodiments of the present application, "one or more" means one, two or more than two; "and / or" describes the association relationship of associated objects and means that three relationships can exist; for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0060] Reference to "one embodiment" or "some embodiments" etc. described in this specification means that a specific feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, the statements "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "include", "comprise", "have" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0061] The "multiple" involved in the embodiments of the present application means greater than or equal to two. It should be noted that in the description of the embodiments of the present application, words such as "first" and "second" are only used for the purpose of distinguishing descriptions and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0062] For ease of understanding, the concepts involved in the present application will be described first below.

[0063] 1. The car body number, train number, and communication group number of the train; among them, the train number is the train number of the train and can be changed; the car body number is used to uniquely indicate the train and belongs to the unique identifier of the train; each train is provided with a communication group number, and the dispatching desk can call the train through the communication group number, and then the on-vehicle station responds.

[0064] 2. The on-vehicle station, which can be installed at the head of the train and is used to communicate with the dispatching desk and receive train operation dispatching instructions; among them, there is a corresponding relationship between the on-vehicle station and the car body number.

[0065] 3. An alarm device, usually installed on each door of each carriage of a train, which can communicate with an on-vehicle station; among them, the alarm device also has a corresponding relationship with the car body number.

[0066] 4. The train operation dispatching generally consists of a dispatching console, a dispatching server, and an on-vehicle station. The dispatching server and the dispatching console can form a dispatching system. The database of the dispatching server will default-configure all train data, including the car body number of the train, the on-vehicle station number, the call group number, etc. The dispatching server loads these train data at the beginning of startup. Therefore, the dispatching server can know information such as the current train number, car body number, and train call group number of each train. The dispatching console is a client, and the dispatcher can log in to the dispatching server through the dispatching console. The dispatching console can call all terminals, including the on-vehicle station, the handheld terminals of the on-board personnel, etc.

[0067] It can be understood that the relevant introduction of the above concepts is only for facilitating the understanding of the technical solution of this application, and does not constitute any limitation to this application.

[0068] In the initial stage of the development of rail transit, the driving of trains was mainly completed manually. The driver needed to be responsible for a series of operations such as starting and driving the train, and also needed to handle the relevant processing after the passengers on the train pressed the alarm device. Taking the subway train as an example, as Figure 1 shown, a passenger emergency alarm device 101 is installed on the subway train. When a passenger encounters an emergency, the driver will be notified through the passenger emergency alarm. After receiving the information, the driver will contact the station staff of the nearest station for emergency handling.

[0069] With the progress of technology, driverless technology has begun to be introduced into rail transit. Similarly, taking the subway train as an example, as Figure 1 shown, after the subway enters the driverless stage, there is no driver on the subway train, but for the safety of passengers, on-board personnel are generally arranged. If a passenger presses the alarm device 101, the alarm device 101 can be connected to the dispatching hall and communicate with the dispatcher. At this time, the dispatcher will coordinate the on-board personnel on the train for emergency handling.

[0070] It can be understood that the "on-board personnel" of the train can also be called the "on-board driver", which refers to the staff on the driverless train who carry communication devices with them and can communicate with the dispatcher in the dispatching hall.

[0071] However, in the case of driverless operation, the on-board personnel may board the train randomly and have no fixed relationship with the train. The dispatcher needs to first query and contact which on-board personnel, and then notify the on-board personnel for emergency handling. Therefore, when a passenger presses the alarm device, contact with the on-board personnel cannot be established immediately, and the on-board personnel need to wait for the dispatcher's notice to carry out emergency disposal, and cannot respond in the first time, which reduces the response efficiency to emergencies.

[0072] Moreover, the on-board personnel are equipped with communication terminals, but they cannot directly participate in the passenger alarm calls to obtain information. All information is notified by the dispatcher, resulting in information lag and second-hand information transmission.

[0073] To solve these problems, an embodiment of the present application proposes a communication method.

[0074] As Figure 4 shown, the communication method provided by the embodiment of the present application includes:

[0075] S101. The first communication device obtains a train identifier.

[0076] The first communication device is a handheld device of the train on-board personnel. After the train on-board personnel enter the train, they can control the first communication device to send the train identifier and the first communication device identifier to the second communication device. In response to the control of the train on-board personnel, the first communication device obtains the train identifier and the first communication device identifier. In one implementation, the train on-board personnel can input the train identifier to the first communication device.

[0077] In some embodiments, the train identifier can be, but is not limited to, the car body number. The train identifier can also be other numbers or codes that can uniquely represent the train. The train identifier can also be used as a call group number or has a corresponding relationship with the call group number of the train group. The members of the train group include the on-vehicle station of the train and the first communication device.

[0078] In other embodiments, the first communication device can also obtain the first communication device identifier, which can be, but is not limited to, a communication number and belongs to the unique ID representing the terminal. For example, the first communication device is a mobile terminal such as a narrowband terminal, an LTE terminal, or a 5G terminal, and the mobile terminal can also be a dual-mode interphone, etc. The first communication device identifier is the communication number of the mobile terminal.

[0079] S102. The first communication device sends the train identifier and the first communication device identifier to the second communication device.

[0080] In some embodiments, the second communication device can be an on-vehicle station and a dispatching system. One implementation of the first communication device sending the train identifier and the first communication device identifier to the second communication device simultaneously is: the first communication device sends a short message to the second communication device, and the short message includes the train identifier and the first communication device identifier.

[0081] In some embodiments, the second communication device is an on-vehicle station. The first communication device sends the train identifier and the first communication device identifier to the on-vehicle station, so that the on-vehicle station constructs and saves the mapping relationship between the first communication device and the on-vehicle station. Further, the on-vehicle station transmits the mapping relationship to the dispatching system.

[0082] In some embodiments, the second communication device is a dispatching server. Another implementation manner for the first communication device to send the train identifier and the first communication device identifier to the second communication device is as follows: The first communication device logs in to the second communication device through an application. The user inputs the train identifier and the first communication device identifier on the interface of the application. In response to the input operation, the first communication device sends the train identifier and the first communication device identifier to the second communication device. The first communication device logs in to the second communication device through the application, which can be understood as: The first communication device is configured with an application, which belongs to the client corresponding to the second communication device. The user inputs login information such as a certificate number and a password in the application to access the second communication device. This enables the dispatching server to construct and save the mapping relationship between the first communication device and the in-vehicle station corresponding to the train. Further, the dispatching server transmits the mapping relationship and / or the first communication device identifier to the corresponding in-vehicle station.

[0083] S103. The second communication device establishes a mapping relationship between the first communication device and the in-vehicle station.

[0084] The second communication device can obtain the in-vehicle station identifier of the train. After receiving the train identifier and the first communication device identifier, the second communication device can construct a mapping relationship between the first communication device and the in-vehicle station. In this way, the second communication device can clarify the binding relationship among the first communication device of the on-board personnel, the train on which they log in, and the in-vehicle station of that train.

[0085] In some embodiments, the second communication device can store the mapping relationship between the train and the in-vehicle station. In this mapping relationship, the train is indicated by the train identifier, and the in-vehicle station is indicated by the in-vehicle station number. In a possible implementation manner, the second communication device can also store the mapping relationship between the train and the warning device. Similarly, in this mapping relationship, the train is indicated by the train identifier, and the warning device is indicated by the identifier of the warning device.

[0086] After receiving the train identifier and the first communication device identifier, the second communication device can construct a mapping relationship between the train identifier and the first communication device identifier. It can be understood that since the train identifier also corresponds to an in-vehicle station, a mapping relationship is established among the train identifier, the first communication device, and the in-vehicle station. In a possible implementation manner, the train identifier also corresponds to the identifier of the warning device. Therefore, a mapping relationship is also established among the train, the first communication device, the in-vehicle station, and the warning device.

[0087] It can be understood that the warning device of the train can be communicatively connected to the in-vehicle station and the dispatching system.

[0088] S104. When the second communication device receives the first warning information, it sends the second warning information to the first communication device.

[0089] In some embodiments, the second warning message may include the talk group number of the train. The second communication device may determine the talk group number of the train based on the mapping relationship, and obtain the second warning message based on the talk group number.

[0090] In some application scenarios, a passenger on the train presses the warning device, and the warning device generates a first warning message in response to the operation of the passenger. Moreover, the warning device also establishes a communication link with the second communication device to achieve a communication connection, and the warning device sends the first warning message to the second communication device. In some embodiments, the first warning message includes the train identification number of the train body, and may also include the car number and the car door number of the train. Among them, the warning device corresponding to the train body number, the car number, and the car door number is pressed by the passenger.

[0091] The second communication device receives the first warning message, and based on the mapping relationship among the train, the first communication device, and the vehicle-mounted station, determines the first communication device corresponding to the train identification in the first warning message, and determines the talk group number of the train corresponding to the train identification in the first warning message, that is, the talk group number of the train where the passenger pressing the warning device is located.

[0092] In some embodiments, the second communication device is a vehicle-mounted station. When multiple warning devices issue warnings, the vehicle-mounted station can connect and process them in sequence according to the priority, reception time, etc. That is: the vehicle-mounted station receives multiple first warning messages sent by the multiple warning devices; determines a first warning message for processing based on preset conditions, and then executes step S104. Of course, the preset conditions are requirements such as the priority order and the order of reception time.

[0093] After the second communication device determines the first communication device corresponding to the train identification in the first warning message, it generates a second warning message. The second warning message may include the talk group number of the train, and may also send the second warning message to the first communication device to notify the on-board personnel of the first communication device that a passenger in the train has issued a warning.

[0094] In some embodiments, the second warning message may further include the train identification, the car number, and the car door number. The warning device corresponding to the car door indicated by the train identification, the car number, and the car door number generates the first warning message.

[0095] Similar to the foregoing content, the second communication device may be a vehicle-mounted station and / or a dispatching system. It can be understood that: the first communication device sends the train identification and the first communication device identification to the vehicle-mounted station, and the vehicle-mounted station may send the second warning message to the first communication device; the first communication device sends the train identification and the first communication device identification to the dispatching system, and the dispatching system may send the second warning message to the first communication device.

[0096] S105. The first communication device obtains the talk group number of the train.

[0097] In some embodiments, the implementation manner for the first communication device to obtain the call group number is as follows:

[0098] Query and obtain the call group number according to the train identifier; and / or, when the second warning information includes the call group number, obtain the call group number according to the second warning information.

[0099] It can be understood that the train identifier can be used as the train number and also as the call group number. Based on this, if the first communication device obtains the train identifier, it obtains the call group number.

[0100] Step S105 is not limited to Figure 4 the execution order, and it can also be that after the first communication device obtains the train identifier, it can obtain the call group number of the train, etc.

[0101] S106. The first communication device establishes a call with the warning device through the on-vehicle radio based on the call group number.

[0102] It should be noted that when a passenger on the train presses the warning device, since the warning device can be connected to the on-vehicle radio and the on-vehicle radio can communicate with the dispatching desk, in response to the passenger's operation, the warning device can also communicate with the dispatching desk through the on-vehicle radio. In this way, when a voice call is established between the on-vehicle radio and the dispatching desk based on the call group number of the train, the warning voice input by the passenger through the warning device can be monitored by the on-vehicle radio and the dispatching desk.

[0103] After receiving the second warning information, the first communication device can access the voice call between the on-vehicle radio and the dispatching desk based on the communication group number of the train. Based on this, the first communication device can monitor the warning voice input by the passenger through the warning device, and the first communication device can also send voice, and the voice sent by the first communication device can also be monitored by the passenger through the warning device.

[0104] In some embodiments, before the first communication device establishes a call with the warning device through the on-vehicle radio based on the call group number, it further includes: the first communication device sets the train group as the waiting group according to the train identifier or the second warning information, where the waiting group is the group where the first communication device is located and receives call information.

[0105] It can be understood that the waiting group can be one or more groups. The call information of the groups that are not or do not belong to the waiting group is generally not received by the first communication terminal. The waiting group can also be the current group. The first communication device defaults to making calls to the current group. The first communication device switches the setting of the train group to the waiting group. Therefore, the first communication device can access the call of the on-vehicle radio.

[0106] In some other embodiments, the first communication device may also switch the train group number to the call group number of the train, that is, switch the current call group to the train group corresponding to the call group number. The specific implementation method can be seen in the content of the following embodiments and will not be elaborated here.

[0107] In the embodiments of the present application, the first communication device sends the train identifier and the first communication device identifier to the on-vehicle station and / or the dispatching system, so as to prompt the on-vehicle station and / or the dispatching system to establish a mapping relationship between the first communication device and the on-vehicle station. After the warning device generates the first warning information, the on-vehicle station and / or the dispatching system can determine the call group number of the train where the warning occurs based on the first warning information and the mapping relationship. The first communication device can obtain the call group number, and the first communication device accesses the voice call of the on-vehicle station and the warning device based on the call group number of the train where the warning occurs, so that the on-vehicle personnel can directly participate in the passengers' call through the first communication device, receive first-hand information, avoid information lag, and do not require the dispatching system to forward messages, and can also improve the response efficiency of the on-vehicle personnel to the warning situation.

[0108] The following introduces the communication method provided by the present application in three embodiments respectively.

[0109] Embodiment 1

[0110] The second communication device is, for example, the dispatching server of the dispatching system. In Embodiment 1, the dispatching server establishes and releases the mapping relationship among the train, the first communication device, and the on-vehicle station.

[0111] As Figure 5 shown, the communication method provided in this embodiment includes:

[0112] S201. The first communication device obtains the train identifier and the first communication device identifier.

[0113] Among them, for the specific implementation method of step S201, reference can be made to the content of the foregoing step S101 and will not be elaborated here.

[0114] S202. The first communication device sends the train identifier and the first communication device identifier to the dispatching server.

[0115] In some embodiments, the first communication device may send the train identifier and the first communication device identifier to the dispatching server by means of a short message or logging in to the dispatching server.

[0116] S203. The dispatching server establishes a mapping relationship between the first communication device and the on-vehicle station.

[0117] It is understandable that in the initial stage of the dispatching server startup, all train information can be obtained, and the train information can include train identifiers and on-vehicle console identifiers of multiple trains. Therefore, when the dispatching server receives the train identifier and the first communication device identifier, it can clarify which train the on-board personnel are currently on through the train identifier. The dispatching server establishes a mapping relationship among the train identifier, the first communication device identifier, and the on-vehicle console. In this mapping relationship, the on-vehicle console can be indicated by the on-vehicle console identifier.

[0118] When the on-board personnel get off the train to withdraw from the current train duty, the mapping relationship among the train, the first communication device, and the on-vehicle console can also be released through the following steps S204 and S205.

[0119] S204. The first communication device sends an instruction to withdraw from on-board service to the dispatching server.

[0120] When the on-board personnel get off the train, the on-board personnel can also operate the first communication device to send an instruction to withdraw from on-board service to the dispatching server. This instruction to withdraw from on-board service is used to release the mapping relationship among the train identifier, the first communication device identifier, and the on-vehicle console. In some embodiments, the instruction to withdraw from on-board service may include the train identifier and the first communication device identifier.

[0121] Among them, the first communication device can also send an instruction to withdraw from on-board service to the dispatching server by means of a short message or logging in to the dispatching server.

[0122] S205. In response to the instruction to withdraw from on-board service, the dispatching server releases the mapping relationship between the first communication device and the on-vehicle console.

[0123] The dispatching server receives the instruction to withdraw from on-board service and, in response to the instruction to withdraw from on-board service, releases the mapping relationship between the first communication device and the on-vehicle console.

[0124] After the on-board personnel board a train and the dispatching server establishes the mapping relationship between the first communication device identifier and the on-vehicle console, the on-board personnel can listen to the alarm information of the passengers through the first communication device. The following combination Figure 6 , will illustrate this process.

[0125] As Figure 6 shown, the communication method provided in this embodiment includes:

[0126] S301. The alarm device generates the first alarm information.

[0127] In some application scenarios, when a passenger on a train (such as train A) presses the alarm device, the alarm device generates the first alarm information in response to the operation of the passenger. In some embodiments, the first alarm information includes the train identifier of the train body number of train A, and may also include the car number and the car door number of train A, where the alarm device corresponding to the car number and the car door number is pressed by the passenger.

[0128] S302. The alarm device sends a first alarm message to the on-vehicle station.

[0129] After the alarm device generates the first alarm message, the alarm device also establishes a communication link with the on-vehicle station and sends the first alarm message to the on-vehicle station based on this communication link. Among them, the on-vehicle station is the on-vehicle station of Train A.

[0130] S303. The on-vehicle station sends the first alarm message to the dispatching server.

[0131] Since the dispatching server stores the mapping relationship between the train identification, the first communication device identification and the on-vehicle station, after the on-vehicle station receives the first alarm message, the on-vehicle station sends the first alarm message to the dispatching server, which can facilitate the dispatching server to clarify the first communication device identification of the on-vehicle personnel corresponding to the train (i.e., Train A) with the ride alarm, and the call group number of Train A.

[0132] S304. The dispatching server searches for the first communication device corresponding to the train and the call group number of the train in the mapping relationship.

[0133] The mapping relationship between the train, the first communication device and the on-vehicle station includes the first communication devices and on-vehicle stations corresponding to multiple trains. Therefore, after the dispatching server receives the first alarm message, it can screen out the first communication device corresponding to the train identification (i.e., Train A) in the mapping relationship based on the train identification in the first alarm message. The dispatching server can also determine the call group number of the train identification (i.e., Train A) in the first alarm message from the stored train information.

[0134] S305. The dispatching server sends a second alarm message to the first communication device.

[0135] Optionally, the second alarm message may include the call group number of the train.

[0136] After the dispatching server determines the first communication device corresponding to the train identification (i.e., Train A) in the first alarm message and the call group number of the train, it can generate a second alarm message, and the second alarm message includes the call group number of the train, that is, the call group number of Train A. Moreover, the dispatching server determines the first communication device based on the first communication device identification and sends the second alarm message to the first communication device. In this way, the on-vehicle personnel of the first communication device can clarify the alarm issued by the passengers in the train where they are based on the second alarm message.

[0137] In some embodiments, the dispatching server may send the second alarm message to the first communication device by short message. In other embodiments, when the first communication device logs in to the dispatching server, the dispatching server can display an application interface on the display screen of the first communication device and display the second alarm message in this application interface.

[0138] In some embodiments, the second warning information may further include a train identifier, a car number, and a car door number. The first warning information received by the dispatching server includes the car number and the car door number. Based on the first warning information, the dispatching server determines the car number and the car door number in the second warning information.

[0139] In one implementation, after receiving the second warning information, the first communication device may output the second warning information. In one application scenario, the first communication device is a mobile terminal. The way for the first communication device to output the second warning information may be: displaying the second warning information on a display screen and / or playing the second warning information by voice. The display screen may display the second warning information through an application interface. In another application scenario, the first communication device is a walkie-talkie. The way for the first communication device to output the second warning information may be: displaying the second warning information on a display screen and / or playing the second warning information by voice. The display screen usually displays the text of the second warning information.

[0140] The second warning information includes a train identifier, a car number, and a car door number. The on-board personnel can determine the location of the warning device that issues the warning based on the train identifier, the car number, and the car door number.

[0141] S306. The first communication device switches the train group number to the call group number of the train.

[0142] After receiving the second warning information, the first communication device switches the train group number (i.e., the current group) to the call group number of the train in the second warning information, that is, switches the current call group to the train group corresponding to the call group number. In this way, the first communication device can access the voice call initiated based on the call group number of the train, that is, access the voice call of the current train group.

[0143] In some embodiments, the first communication device can implement switching the train group number to the call group number of the train in the following two ways:

[0144] Method 1: The user manually switches according to the received call group number.

[0145] Method 2: The dispatching server of the dispatching system instructs the first communication device to switch to the corresponding call group number according to the call group number. Optionally, the dispatching server may send a control instruction to the first communication device to instruct the first communication device to switch to the corresponding call group number.

[0146] It can be understood that before the first communication device executes step S306, it may first obtain the call group number of the train. Optionally, in addition to obtaining the call group number in the second warning information, the first communication device may also query and obtain the call group number according to the train identifier.

[0147] In some other embodiments, the first communication device may also set the train group as a waiting group according to the train identifier or the second warning information, where the waiting group is the group where the first communication device is located and receives call information. For details, refer to the foregoing content and will not be elaborated here.

[0148] S307. The dispatching server sends the second warning information to the dispatching console.

[0149] Optionally, the second warning information includes the call group number of the train.

[0150] After receiving the first warning information, the dispatching server may also send the second warning information to the dispatching console through step S307.

[0151] Understanding: There is no limitation on the execution order of steps S305 and S307. In some embodiments, the dispatching server may also execute step S307 first and then step S305.

[0152] S308. The on-vehicle station and the dispatching console establish a voice call based on the call group number of the train.

[0153] After receiving the second warning information, the dispatching console may establish a voice call with the on-vehicle station based on the call group number of the train in the second warning information. After that, it may monitor the voice call of the on-vehicle station, and may also monitor the voice call sent by the warning device through the on-vehicle station.

[0154] Moreover, since the first communication device accesses the on-vehicle station and the dispatching console to establish a voice call based on the call group number of the train, the first communication device can also monitor the voice call of the on-vehicle station, and can also monitor the voice call sent by the warning device through the on-vehicle station, and can also monitor the voice call sent by the dispatching console, and can also send voice, thus enabling the on-train personnel to directly interact with passengers and dispatchers through the first communication device.

[0155] Embodiment 2

[0156] The second communication device is, for example, an on-vehicle station. In Embodiment 2, the first communication device communicates with the on-vehicle station through the dispatching server, and the on-vehicle station establishes and cancels the mapping relationship between the train, the first communication device and the on-vehicle station.

[0157] As Figure 7 shown, the communication method provided in this embodiment includes:

[0158] S401. The first communication device obtains the train identifier and the first communication device identifier.

[0159] Among them, for the specific implementation manner of step S401, refer to the content of step S101 described above and will not be elaborated here.

[0160] S402: The first communication device sends a train identifier and a first communication device identifier to a dispatch server.

[0161] In some embodiments, the first communication device may send the train identifier and the first communication device identifier to the dispatch server via a short message or by logging into the dispatch server.

[0162] S403: The dispatch server sends a train identifier and a first communication device identifier to the vehicle-mounted station.

[0163] The dispatch server receives the train identifier and the first communication device identifier, and may forward the train identifier and the first communication device identifier to the vehicle-mounted station.

[0164] S404: The vehicle-mounted station establishes a mapping relationship between the first communication device and the vehicle-mounted station.

[0165] After receiving the first communication device identifier and the train identifier, the vehicle-mounted station can clearly identify the person carrying the first communication device on the train indicated by the train identifier, and the vehicle-mounted station constructs a mapping relationship between the first communication device and the vehicle-mounted station. In the mapping relationship, the vehicle-mounted station is indicated by the vehicle-mounted station identifier.

[0166] S405. The first communication device sends an instruction to exit the vehicle to the dispatch server.

[0167] When the train attendant gets on or off the train, the train attendant may also control the first communication device, and the first communication device sends an exit instruction to the dispatch server, and the exit instruction is used to release the mapping relationship between the train, the first communication device, and the vehicle-mounted station. In some embodiments, the exit instruction may include a train identifier and a first communication device identifier.

[0168] The first communication device may also send a command to exit the vehicle to the dispatch server via a short message or by logging into the dispatch server.

[0169] S406: The dispatch server sends a command to the vehicle-mounted station to exit the vehicle.

[0170] When the dispatch server receives the instruction to exit the vehicle, it can forward the instruction to exit the vehicle to the vehicle-mounted station.

[0171] S407: The vehicle-mounted station releases the mapping relationship between the first communication device and the vehicle-mounted station in response to the instruction to exit the vehicle.

[0172] The vehicle-mounted station receives the instruction of exiting the vehicle, and in response to the instruction of exiting the vehicle, releases the mapping relationship between the first communication device and the vehicle-mounted station.

[0173] The following combination Figure 8 , the process of the accompanying personnel monitoring the passenger's warning information through the first communication device is explained.

[0174] As Figure 8 shown, the communication method provided in this embodiment includes:

[0175] S501. The alarm device generates a first alarm message.

[0176] For the specific implementation manner of step S501, refer to the content of the foregoing step S301, which will not be elaborated here.

[0177] S502. The alarm device sends the first alarm message to the vehicle-mounted station.

[0178] For the specific implementation manner of step S502, refer to the content of the foregoing step S302, which will not be elaborated here.

[0179] After the vehicle-mounted station receives the first alarm message, the following steps S503 and S504 can be executed. And the execution order of steps S503 and S504 is not limited to Figure 8 shown.

[0180] S503. The vehicle-mounted station sends the first alarm message to the dispatching server.

[0181] Since the dispatching server is required to send a second alarm message to the dispatching console, therefore, after the vehicle-mounted station receives the first alarm message, it can send the first alarm message to the dispatching server.

[0182] S504. The vehicle-mounted station looks up the first communication device corresponding to the train and the call group number of the train in the mapping relationship.

[0183] For the train, the mapping relationship between the first communication device and the vehicle-mounted station includes the first communication device identifiers and vehicle-mounted station identifiers corresponding to multiple trains. Therefore, after the vehicle-mounted station receives the first alarm message, it can screen out the first communication device corresponding to the train based on the train identifier (i.e., Train A) in the first alarm message. The vehicle-mounted station can also determine the call group number of the train identifier (i.e., Train A) in the first alarm message.

[0184] S505. The vehicle-mounted station sends a second alarm message to the first communication device.

[0185] Optionally, the second alarm message may include the call group number of the train.

[0186] After the vehicle-mounted station determines the first communication device corresponding to the train identifier (i.e., train A) in the first warning message and the call group number of the train, it can generate a second warning message, which may include the call group number of the train, that is, the call group number of train A. Moreover, the vehicle-mounted station determines the first communication device based on the first communication device identifier and sends the second warning message to the first communication device. In this way, the on-board personnel of the first communication device can issue a warning based on the second warning message to the passengers in the train where they are located.

[0187] In some embodiments, the vehicle-mounted station sends the second warning message to the first communication device via a short message.

[0188] In some embodiments, the second warning message may further include the train identifier, the carriage number, and the carriage door number. The first warning message received by the vehicle-mounted station includes the carriage number and the carriage door number, and the vehicle-mounted station determines the carriage number and the carriage door number in the second warning message based on the first warning message.

[0189] In one implementation, after the first communication device receives the second warning message, it can output the second warning message. In one application scenario, the first communication device is a mobile terminal, and the way for the first communication device to output the second warning message can be: displaying the second warning message on the display screen and / or playing the second warning message by voice, and the display screen can display the second warning message through the application interface. In another application scenario, the first communication device is a walkie-talkie, and the way for the first communication device to output the second warning message can be: displaying the second warning message on the display screen and / or playing the second warning message by voice, and the display screen usually displays the second warning message text.

[0190] The second warning message includes the train identifier, the carriage number, and the carriage door number. The on-board personnel can determine the location of the warning device that issues the warning through the train identifier, the carriage number, and the carriage door number.

[0191] S506. The first communication device switches the train group number to the call group number of the train.

[0204] In some embodiments, the first communication device may send the train identifier and the first communication device identifier to the on-vehicle station by means of a short message or the like.

[0205] S603. The on-vehicle station establishes the mapping relationship between the first communication device and the on-vehicle station.

[0206] The on-vehicle station locally stores the train identifier corresponding to itself. After receiving the first communication device identifier and the train identifier, the on-vehicle station can clearly identify that the on-board personnel carrying the first communication device board the train indicated by the train identifier, and the on-vehicle station then constructs the mapping relationships among the train, the first communication device, and the on-vehicle station. In this mapping relationship, the on-vehicle station is indicated by the on-vehicle station identifier.

[0207] S604. The first communication device sends an instruction to quit accompanying the train to the on-vehicle station.

[0208] When the on-board personnel get off the train, the on-board personnel can also control the first communication device to send an instruction to quit accompanying the train to the on-vehicle station, and this instruction to quit accompanying the train is used to release the mapping relationships among the train, the first communication device, and the on-vehicle station. In some embodiments, the instruction to quit accompanying the train may include the train identifier and the first communication device identifier.
