[0030] Embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0031] A train alarm method and a train alarm system according to embodiments of the present application are described below with reference to the accompanying drawings.

[0032] In embodiments of the present application, as shown in Figure 1 is a schematic diagram of a train alarm system architecture according to an embodiment of the present application, based on a vehicle control system, a center control system and a broadcast system, which are in real-time communication. For an alarm with high real-time requirement or high safety requirement, the vehicle control system can send an alarm according to the definition of the system itself when such a fault occurs. And the alarm can be transmitted to the center control system of the dispatch system and the broadcast system through the communication module respectively. When receiving such an alarm, the broadcast system sends a broadcast announcement; when receiving the alarm, the center control system of the dispatch system can send a command to stop playing to the broadcast system to stop the broadcast after confirming the receipt of the alarm, so as to confirm that the accident or fault of the vehicle is timely notified to the dispatcher or administrator.

[0033] In embodiments of the present application, the alarm is not limited to the dispatch system, and the notification range of the alarm can be wider; the dispatch center can install the broadcast of the broadcast system in the place where it is needed or where there are staff according to the demand, so that even if no one finds the alarm of the dispatch system, the broadcast of the broadcast system can also remind the staff in time, which is more timely and fast, and improves the safety of train operation.

[0034] The vehicle control system, the center control system and the broadcast system are described below respectively.

[0035] Figure 2 is a flowchart of a train alarm method according to an embodiment of the present application, which can be used in the vehicle control system. Each vehicle can be configured with an independent vehicle control system. In embodiments of the present application, the vehicle control system can be configured with fault events that need to be alarmed according to the demand.

[0036] As shown in Figure 2 , the train alarm method of embodiments of the present application includes:

[0037] S1, detecting that an alarm event occurs in the train.

[0038] Specifically, the vehicle-mounted control system can obtain various detection information and fault detection information through the bus, determine that an alarm event occurs in the train according to the detection information, the alarm event can include events of different levels, and the alarm event level can be configured according to requirements.

[0039] S2, determining the type of the alarm event.

[0040] In actual operation, high-level alarms can be configured according to requirements, and linkage alarms can be performed for high-level alarms, for example, linkage of the central control system and the broadcast system of the dispatch center.

[0041] For example, the type of the alarm event can be determined according to configuration information, for example, an alarm event that urgently needs to be handled and endangers safety can be configured as a high-level alarm, other alarm events that do not endanger safety can be configured as a medium-level alarm, and other alarm events that can be ignored can be configured as a low-level alarm.

[0042] S3, determining that the alarm event needs a linkage alarm according to the type of the alarm event.

[0043] Specifically, for example, linkage alarms need to be performed for high-level alarms, so that personnel can handle in time to avoid accidents endangering life safety. For medium-level alarm events or low-level alarm events, the vehicle-mounted control system of the train can usually handle, and can timely perform an alarm to notify train management personnel.

[0044] For example, in some embodiments, determining the alarm event includes at least one of the following: a linkage failure between a platform door and a vehicle door, a vehicle fire, a vehicle emergency braking, a loss of vehicle positioning, a car fault alarm, and a vehicle active disconnection of traction, and it is considered that the alarm event needs a linkage alarm.

[0045] S4, sending the alarm event to a broadcast system and a central control system of a train line, respectively.

[0046] The vehicle-mounted control system can not only configure alarm events, but also define respective fault contents of communication protocol packets by the vehicle-mounted control system, the central control system, and the broadcast system.

[0047] Specifically, when it is determined that the alarm event needs a linkage alarm, the vehicle-mounted control system sends the alarm event to the broadcast system and the central control system of the train line, respectively. Then, the central control system receives the linkage alarm event and performs an alarm prompt, and dispatch personnel can handle in time. The broadcast system receives the linkage alarm event and performs a broadcast of the alarm event in time, and can also perform a play in a progressive area according to a configured broadcast play area, to timely notify relevant personnel.

[0048] According to the train alarm method, when the vehicle-mounted control system determines that the alarm event needs to be alarmed in linkage according to the level of the alarm event, linkage alarm is realized, alarm event sending and receiving can better adapt to the development needs of the current intelligent dispatching system, and the coupling between systems and the circulation of messages are reduced, so that message transmission is faster and more accurate, and train operation safety is improved.

[0049] The train alarm method further includes: when it is determined that the alarm event is released, a release alarm request is sent to the central control system, so that the central control system sends an instruction to stop broadcasting the alarm event to the broadcasting system.

[0050] The train alarm method on the broadcasting system side according to the second aspect of the present application is described below with reference to the accompanying drawings.

[0051] As Figure 3 The flowchart of the train alarm method according to an embodiment of the present application is shown in FIG. 1. Figure 3

[0052] S11, real-time communication with a train line train-mounted control system and a central control system.

[0053] S12, receiving an alarm event sent by the vehicle-mounted control system.

[0054] S13, obtaining configuration information of the alarm event.

[0055] Specifically, in the broadcasting system, the fault event defined in the vehicle-mounted control system is configured according to the demand, and the corresponding area requiring broadcast is configured.

[0056] For example, the broadcast play time of each level area is set in the broadcasting system; according to the alarm level, the broadcast play time is set, and after the limited play time, if there is still no one to handle, the play is performed in the progressive area of the configured broadcast play area.

[0057] S14, broadcasting the alarm event according to the configuration information of the alarm event.

[0058] For example, according to the configuration information such as alarm event level information, it is determined which play area needs to play and play the event, and the play is performed according to the configuration information, so that the broadcast of the alarm event can be performed in a wide range in time, and the speed and accuracy of message transmission are improved.

[0059] ​In some embodiments, the broadcasting system can configure the train linkage alarm event, such as configuring alarm regions of different levels of alarm events and continuous events, different levels of alarm events can be broadcasted in different alarm regions or configuring different broadcast events or playing order of different broadcast regions, so as to improve the propagation speed and accuracy of the alarm event.

[0060] Specifically, the level information of the alarm event is identified; the alarm target region and the playing order of the alarm target region are obtained according to the level information of the alarm event; and the alarm event is played in each alarm target region according to the playing order of the alarm target region.

[0061] For example Figure 4 For example, the flowchart of the train alarm method according to an embodiment of the present application is shown in FIG. 1, which includes: Figure 4

[0062] S110, the broadcasting system receives the alarm event sent by the on-board control system.

[0063] S111, the level and configuration information of the alarm event are determined.

[0064] S112, the configuration information is sent to the broadcast A region.

[0065] S113, the broadcast device of the broadcast A region broadcasts.

[0066] S114, the playing time of the broadcast A region is recorded, and if the playing time of the broadcast A region is determined to be timeout and not processed, the next level configuration of the alarm event is determined.

[0067] S115, the next level configuration of the alarm event is sent to the broadcast B region.

[0068] S116, the broadcast device of the broadcast B region broadcasts.

[0069] S117, the playing time of the broadcast B region is recorded, and if the playing time of the broadcast B region is determined to be timeout and not processed, the next level configuration of the alarm event is determined.

[0070] S118, the next level configuration of the alarm event is sent to the broadcast C region.

[0071] S119, the broadcast device of the broadcast C region broadcasts.

[0072] As described above, until all the alarm target regions of the alarm event are played.

[0073] ​The duration of playing the alarm event in the current alarm target area is recorded, and when the duration reaches the set duration, the alarm event is sent to the next alarm target area in the current alarm target area for playing until a stop playing instruction is received or all alarm target areas finish playing. The box event of each alarm target area is monitored, and when there is no response in one of the alarm target areas for a period of time, the playing area can be changed in time to improve the speed and effectiveness of information dissemination.

[0074] In an embodiment, the broadcast system determines that all alarm target areas configured by the alarm event have played the alarm event, and no stop playing instruction is received, and then a status signal of alarm event playing ending is fed back to the central control system, so that the central control system can remind relevant personnel to take timely measures to improve the safety of train operation on the train line.

[0075] The train alarm method on the central control system side of train dispatching according to the third aspect of the embodiment of the present application is described below with reference to the accompanying drawings.

[0076] Figure 5 The flowchart of the train alarm method according to an embodiment of the present application is shown in FIG. 1, which includes the following steps. Figure 5

[0077] S21, real-time communication with the on-board control system and the broadcast system of the train line.

[0078] S22, receiving the alarm event sent by the on-board control system, wherein the alarm event is sent by the on-board control system to the broadcast system and the central control system when it is determined that the alarm event needs to be jointly alarmed.

[0079] Similarly, the fault content also needs to be defined in the central control system, and needs to be consistent with the definition of the on-board control system and the broadcast system.

[0080] S23, issuing an alarm according to the alarm event.

[0081] For example, a pop-up window is displayed on the monitoring screen, a prominent symbol is prompted, and a voice alarm can also be given by an alarm, so that the dispatch personnel can be reminded in time to take relevant measures to improve the safety of train operation on the train line.

[0082] Further, as shown in FIG. 2, the train alarm method according to the third aspect of the embodiment of the present application includes the following steps. Figure 6 ​As shown, based on the alarm issued by the central control system, dispatchers can operate the central control system, for example, by inputting stop playback information and sending a stop playback command to the broadcast system. That is, in response to the alarm event handling input information, the central control system sends a stop playback command to the broadcast system broadcasting the alarm event, and the broadcast system controls the playback devices in its various areas to stop playing the alarm event. Simultaneously, the central control system can also send processing instructions to the vehicle's onboard control system of the malfunctioning vehicle, or notify relevant personnel for manual on-site handling.

[0083] In some embodiments, such as Figure 7 As shown, the broadcast system plays the alarm event zone by zone and determines whether the broadcast has ended in all zones. If the broadcast has ended, it sends a status signal indicating that the broadcast in the target zone has ended to the central control system. The central control system receives the status signal indicating that the alarm event has ended in the target zone; it obtains the section information of the train belonging to the onboard control system and generates a temporary speed limit value for the section where the train belongs to the onboard control system; it then sends the section information and the temporary speed limit value to all trains on the line where the train belonging to the onboard control system is located, to remind vehicles on the line to implement temporary speed limits when approaching the section, thereby improving safety.

[0084] like Figure 8 As shown, the train alarm system 100 of this embodiment includes an on-board control system 1, a broadcasting system 2, and a central control system 3.

[0085] The onboard control system 1, the broadcasting system 2, and the central control system 3 communicate with each other to implement the train alarm method described in the above embodiment.

[0086] Specifically, when a vehicle experiences an accident or malfunction, an alarm event is triggered and sent to the central control system and the broadcast system. Upon receiving the alarm event, the broadcast system forwards the alarm broadcast to the corresponding alarm area based on the previously configured alarm area, and the broadcast is then played. When the central control system at the dispatch center receives the alarm event reported by the vehicle, it also simultaneously issues an alarm.

[0087] Upon receiving an alarm, dispatch center personnel will operate the central control system. If dispatch center personnel are not at their computers or in the vehicle control room but are in another area where they can hear the emergency broadcast, they will hear the alarm being played. Alternatively, if dispatch center personnel do not respond to the emergency broadcast, the broadcast system will play the fault alarm to the next configured progressive alarm area, cycling through this until someone addresses the alarm in the central control system. After hearing the alarm multiple times, personnel in other areas can proceed to the control center to handle the central control system issue.

[0088] Wherein, when the artificial center control system failure alarm is handled, first, the stop broadcast playing instruction is issued to the broadcast system, indicating that the failure has been known by the personnel and the failure is processed. After receiving the instruction, the broadcast system sends the stop playing instruction to all broadcast devices, and thus the task of the broadcast system is completed.

[0089] Further, considering the extreme case that after all the playing areas are played, the center control system still does not process the unexpected failure event, the broadcast system can feed back a region playing end state signal to the center control system, when the center control system monitors the state value, obtains the section information of the current failure vehicle, sets a temporary speed limit section, and sends the information of the speed limit section to all vehicles running on the line. When the remaining vehicles receive the speed limit information, they will slow down when driving in this section, improving safety.

[0090] The control personnel process according to the reported failure type: if the platform door linkage fails, manual opening or closing of the platform door is required; if the vehicle is on fire, manual rescue, on-site evacuation, and subsequent arrangement of the vehicle are required; other failures such as vehicle positioning loss, vehicle emergency braking, etc. can be configured according to the needs.

[0091] The embodiment of the application also provides a computer readable storage medium, which stores a computer program, and the computer program is executed to realize the train alarm method of the above embodiment.

[0092] The embodiment of the application also provides an electronic device, which comprises a processor and a memory, the memory stores the above computer readable storage medium, and the processor is used to execute the computer program stored in the computer readable storage medium to realize the train alarm method.

[0093] In general, the train alarm method and the train alarm system of the embodiment of the application, the alarm is not only limited to the dispatching system, but also based on the vehicle-mounted control system, the center control system and the broadcast system, multi-directional alarm sending and receiving, which can make the notification range of the alarm wider, more suitable for the development needs of the current intelligent dispatching system, reduce the coupling between the systems and the flow of messages, make the message transmission faster and more accurate, and improve the safety of train operation.
