[0032] In the process of implementing the present disclosure, it was found that the relevant technology mainly broadcasts the arrival and departure information of the train, and is unable to realize voice broadcast of emergency situations under abnormal environments, for example, abnormal situations such as rail breakage, earthquake warning, bumpy road sections, etc., resulting in poor flexibility in voice broadcast information and voice broadcast location.

[0033] In view of this, an embodiment of the present disclosure provides a voice broadcast system for a rail transit train, comprising: a ground control device and a train control device and a passenger information system deployed on a target train, the train control device being communicatively connected to the ground control device, and the train control device being communicatively connected to the passenger information system; wherein the ground control device is used to send target area information, wherein the target area information is information about a target area that is located on the route of a target train in motion and to which the target train has not yet traveled, and the target area is an area for voice broadcasting of the target train; the train control device is used to obtain real-time position information and abnormal road condition information corresponding to the target train, and receive the target area information from the ground control device; based on the abnormal road condition information, adjust the target area range corresponding to the target area information to obtain the target target area information; based on the positional relationship between the real-time position information and the target target area information, generate a voice broadcast instruction; based on the abnormal road condition information, determine the voice broadcast information corresponding to the abnormal road condition information; based on the voice broadcast instruction, control the passenger information system to broadcast the voice corresponding to the voice broadcast information.

[0034] Figure 1The schematic diagram shows an architecture diagram of a voice announcement system for a rail transit train according to an embodiment of the present disclosure.

[0035] like Figure 1 As shown, the voice announcement system 100 of the rail transit train of this embodiment includes a ground control device 110 and a train control device 120 and a passenger information system 130 deployed on the train.

[0036] According to an embodiment of the present disclosure, the target train is a rail transit train. For example, the target train may be an EMU train. The ground control device 110 may represent a device that is deployed outside the target train and can send instructions to the target train. For example, the ground control system may be deployed at a station of the target train or between two stations. The ground control device 110 may be used to send target area information, which may be information about a target area that is located on the route of the target train and to which the target train has not traveled, and the target area may be an area for the target train to perform voice broadcasts.

[0037] According to an embodiment of the present disclosure, the train control device 120 may be deployed on a train, and the train control device 120 may represent a device for controlling a train. The passenger information system 130 may be deployed on a train. The passenger information system 130 may represent a multimedia integrated information system that allows passengers to timely and accurately understand train operation information and public media information through a display terminal on the train. For example, the passenger information system may make voice announcements according to received instructions.

[0038] According to an embodiment of the present disclosure, the train control device 120 can be connected to the ground control device 110 for communication, and the train control device 120 can also be connected to the passenger information system 130 for communication. The train control device 120 can be used to obtain real-time location information and abnormal road condition information corresponding to the target train, and receive target area information from the ground control device 110. The real-time location information can characterize the location to which the target train is currently traveling. The abnormal road condition information can characterize the impact on the track caused by natural factors or other factors. For example, the impact of natural factors of earthquake early warning information on the track, the impact of the front rail break on the track, the impact of train derailment on the track, etc.

[0039] According to the embodiments of the present disclosure, the target area range corresponding to the target area information can be adjusted based on the abnormal road condition information to obtain the target area information. For example, if the abnormal road condition information is earthquake warning information, the target area range corresponding to the target area information is adjusted. If the earthquake warning information is an earthquake warning exceeding level 3, the target area range corresponding to the target area information can be expanded to obtain the target area information.

[0040] According to an embodiment of the present disclosure, a voice broadcast instruction can be generated based on the positional relationship between the real-time position information and the target target area information. When the real-time position information is within the target area range corresponding to the target target area information, a voice broadcast instruction can be generated. When the real-time position information is not within the target area range corresponding to the target target area information, no voice broadcast instruction is generated. Based on the abnormal road condition information, the voice broadcast information corresponding to the abnormal road condition information can be determined. For example, the abnormal road condition information can include multiple types, and each type can include multiple levels. For example, when the abnormal road condition information is a rail break, and the level of the rail break is level one, a voice broadcast information corresponding to the level one rail break can be generated, and the voice broadcast information corresponding to the level one rail break can be a large rail break 150 km ahead, please do not panic. Based on the voice broadcast instruction, the passenger information system 130 can be controlled to broadcast the voice corresponding to the voice broadcast information. When there is a voice broadcast instruction, that is, when the target train arrives within the target area corresponding to the target target area, the passenger information system 130 can be controlled to broadcast the voice corresponding to the voice broadcast information, so as to give voice prompts to the passengers in the target train.

[0041] According to the embodiments of the present disclosure, the train control device can adjust the target area range corresponding to the target area information based on the abnormal road condition information by acquiring the real-time position information and abnormal road condition information corresponding to the target train and receiving the target area information from the ground control device, so as to obtain the target area information corresponding to the abnormal road condition information. When the real-time position information indicates that the target train has traveled to the target area range corresponding to the target target area information, a voice broadcast instruction is generated, and based on the voice broadcast instruction, the passenger signal system is controlled to automatically broadcast the voice corresponding to the voice broadcast information corresponding to the abnormal road condition information, thereby improving the accuracy of the voice broadcast information and the flexibility of the voice broadcast location.

[0042] Figure 2 The following schematically shows an architecture diagram of a voice announcement system for a rail transit train according to another embodiment of the present disclosure.

[0043] like Figure 2 As shown, the voice announcement system 200 of the rail transit train includes a ground control device 110, a train control device 120 and a passenger information system 130. The train control device may include a wireless transmission unit 121, an information processing unit 122 and a train control unit 123.

[0044] According to an embodiment of the present disclosure, the wireless transmission unit 121 can obtain the real-time position information of the train and receive the target area information sent by the ground control device 110, and the wireless transmission unit 121 and the ground control device 110 can be connected via an Ethernet cable.

[0045] According to an embodiment of the present disclosure, the ground control equipment 110 transmits the real-time position information and the target area information to the wireless transmission unit 121, the train control unit 123 transmits the abnormal road condition information to the information processing unit 122, the information processing unit 122 adjusts the target area range corresponding to the target area information according to the abnormal road condition information, obtains the target target area information, determines the corresponding voice broadcast information based on the abnormal road condition information, generates a voice broadcast instruction based on the positional relationship between the target target area information and the real-time position information, and transmits the voice broadcast instruction to the passenger information system 130, and controls the passenger information system 130 to broadcast the voice corresponding to the voice broadcast information.

[0046] According to an embodiment of the present disclosure, the train control device is also used to: determine the impact area information on the track corresponding to the abnormal road condition information based on the abnormal road condition information; adjust the target area range corresponding to the target area information according to the impact area information to obtain the target target area information.

[0047] According to an embodiment of the present disclosure, when abnormal road condition information is determined, the image area information of the track corresponding to the abnormal road condition information can be determined based on the abnormal road condition information. For example, if a 4.2-magnitude earthquake warning occurs at the next station to be reached, it can be determined that the impact area on the track corresponding to the abnormal road condition information is 50 km before and after the next station.

[0048] According to an embodiment of the present disclosure, the target area range corresponding to the target area information can be adjusted according to the image area information. For example, when it is determined that the impact area on the track corresponding to the abnormal road condition information is 50 km before and after the next station, the target area range corresponding to the target area information can be expanded based on the impact area on the track to obtain the target target area information.

[0049] According to the embodiments of the present disclosure, by observing the abnormal road condition information, the impact area information on the track corresponding to the abnormal road condition information can be determined, and the target area range corresponding to the target area information can be adjusted based on the impact area information, thereby achieving flexible adjustment of the target area range, thereby obtaining the target target area information, and improving the flexibility of the voice broadcast location.

[0050] According to an embodiment of the present disclosure, the train control device is also used to: determine the degree of abnormal road conditions corresponding to the abnormal road condition information; determine a target area range from multiple different area ranges based on the degree of abnormal road conditions; and generate impact area information based on the target area range.

[0051] According to an embodiment of the present disclosure, the degree of abnormal road conditions can characterize the degree of road damage, bumpy road conditions or other abnormalities. The degree of abnormal road conditions can be divided into a first level, a second level, and a third level. Based on the degree of abnormal road conditions, a target area range can be determined from a plurality of different area ranges. For example, different area ranges may include a first area range, a second area range, and a third area range. When the degree of abnormal road conditions is at the first level, the first area range can be determined as the target area range from a plurality of different area ranges. When the degree of abnormal road conditions is at the second level, the second area range can be determined as the target area range from a plurality of different area ranges. When the degree of abnormal road conditions is at the third level, the third area range can be determined as the target area range from a plurality of different area ranges.

[0052] According to an embodiment of the present disclosure, the impact area information can characterize the impact area of ​​abnormal road condition information on the rail. The impact area information can be generated based on the target area range, and different target area ranges can correspond to different impact area information. When the target area range is the first area range, the impact area information corresponding to the first area range can be generated. When the target area range is the second area range, the impact area information corresponding to the second area range can be generated. When the target area range is the third area range, the impact area information corresponding to the third area range can be generated.

[0053] According to an embodiment of the present disclosure, when the abnormal road condition information is a rail break, the level of the abnormal road condition information can be determined based on the length of the rail break. For example, when it is determined that the abnormal road condition information belongs to the first level, the area range corresponding to the first level can be determined as the first area range, and the first area range is the target area range. Based on the target area range, corresponding impact area information can be generated, and the range corresponding to the impact area information can be 50 km before and after the rail break.

[0054] According to the embodiments of the present disclosure, the target area range corresponding to the abnormal road condition can be determined, and the impact area information can be generated according to the target area range, thereby improving the accuracy of the generated impact area information.

[0055] According to an embodiment of the present disclosure, the train control device is also used to: generate range difference information by comparing the range corresponding to the impact area information with the range corresponding to the target area information; based on the range difference information, adjust the range corresponding to the target area information to generate target target area information.

[0056] According to an embodiment of the present disclosure, the range corresponding to the impact area information and the range corresponding to the target area information may be compared to generate range difference information. The range corresponding to the impact area information may be larger than the range corresponding to the target area information, or the range corresponding to the impact area information may be less than or equal to the range corresponding to the target area information. In the case where the range corresponding to the impact area information is less than or equal to the range corresponding to the target area information, another type of range difference information may be obtained.

[0057] According to an embodiment of the present disclosure, when the range corresponding to the impact area information is larger than the range corresponding to the target area information, range difference information can be obtained, and based on the range difference information, the range corresponding to the target area information can be expanded to generate the target target area information. When the range corresponding to the impact area information is less than or equal to the range corresponding to the target area information, range difference information can be obtained, and based on the range difference information, the range corresponding to the target area information can be maintained to generate the target target area information.

[0058] According to an embodiment of the present disclosure, range difference information is generated by comparing the range corresponding to the impact area information and the range corresponding to the target area information. Based on the difference information, the range corresponding to the target area information can be adjusted to generate target area information, thereby improving the accuracy of the generated target area information.

[0059] Figure 3 The flowchart of adjusting the target area range according to an embodiment of the present disclosure is schematically shown.

[0060] like Figure 3 As shown, the embodiment 300 of adjusting the target range includes operations S310 to S350.

[0061] In operation S310, real-time position information and abnormal road condition information corresponding to a target train are acquired, and target area information is received.

[0062] In operation S320, based on the abnormal road condition information, a degree of abnormal road condition corresponding to the abnormal road condition information is determined.

[0063] In operation S330 , a target area range is determined from a plurality of different area ranges based on the degree of abnormality of the road condition.

[0064] In operation S340, influence area information is generated based on the target area range.

[0065] In operation S350, the target area range corresponding to the target area information is adjusted according to the impact area information to obtain the target area information.

[0066] According to the embodiments of the present disclosure, by dynamically adjusting the target area range according to abnormal road condition information, the target area information can be flexibly adjusted, so that voice broadcasting can be achieved at a suitable location, thereby improving the riding experience of passengers on the target train. According to the embodiments of the present disclosure, the train control device is also used to: obtain the position relationship by comparing the real-time position information with the target area information; and generate a voice broadcast instruction when the position relationship indicates that the real-time position of the target train is within the target area.

[0067] According to an embodiment of the present disclosure, the area range of the target area may correspond to the target area information. The real-time location information may be compared with the target area information to determine whether the real-time location information is within the target area and obtain a location relationship.

[0068] According to an embodiment of the present disclosure, when the real-time position of the target train represented by the position relationship is within the target area, a voice broadcast instruction can be generated. When the real-time position of the target train represented by the position relationship is not within the target area, a voice broadcast instruction cannot be generated.

[0069] According to an embodiment of the present disclosure, when the real-time position of the target train is within the target area, a voice broadcast instruction can be generated, so that the passenger information system can be controlled to broadcast the voice corresponding to the voice broadcast information based on the voice broadcast instruction, thereby improving the accuracy of the voice broadcast position.

[0070] According to an embodiment of the present disclosure, the train control device is also used to: based on the impact area information, query the voice broadcast information corresponding to the impact area information from the audio database.

[0071] According to an embodiment of the present disclosure, the audio database may represent a database that pre-stores commonly used broadcast audio. Voice broadcast information corresponding to the impact area information may be queried from the audio database. For example, when the impact area information corresponds to a range of 20 km around the abnormal road condition information, the voice broadcast information corresponding to the impact area information may be queried from the audio database, and the voice broadcast information may be that the road ahead is bumpy and the impact range is 20 km.

[0072] According to the embodiments of the present disclosure, by querying the voice broadcast information corresponding to the affected area information from the audio database, the speed of obtaining the voice broadcast information can be improved, so that voice broadcast can be carried out in time when an abnormality is found.

[0073] According to an embodiment of the present disclosure, the train control device is also used to: collect road condition warning audio in response to receiving an instant audio collection instruction; and control the passenger information system to broadcast the road condition warning audio.

[0074] According to the embodiments of the present disclosure, the road condition warning audio can be the audio of the temporary voice broadcast of the crew. In addition to searching the corresponding voice broadcast information from the audio database based on the affected area information, and controlling the passenger information system to broadcast the voice broadcast information of the affected area information, it is also possible to receive an instant audio collection instruction to collect the road condition warning audio, so as to control the passenger information system to broadcast the road condition warning audio, and realize timely reminders to passengers.

[0075] According to the embodiments of the present disclosure, when an instant audio collection instruction is received, road condition warning audio can be collected, thereby controlling the passenger information system to broadcast the road condition warning audio, thereby achieving the goal of not only broadcasting the voice broadcast information corresponding to the affected area information but also broadcasting the collected road condition warning information, avoiding the problem that trains can only broadcast at stations and manually, and improving the flexibility of the passenger information system's broadcast content.

[0076] Based on the above-mentioned voice broadcast system for rail transit trains, the present disclosure also provides a voice broadcast method for rail transit trains.

[0077] Figure 4 The flowchart of the voice broadcasting method of a rail transit train according to an embodiment of the present disclosure is schematically shown.

[0078] like Figure 4 As shown, the voice broadcasting method 400 of the rail transit train includes operations S410 to S450.

[0079] In operation S410, real-time position information and abnormal road condition information corresponding to a target train are acquired, and target area information is received.

[0080] In operation S420, based on the abnormal road condition information, the target area range corresponding to the target area information is adjusted to obtain the target target area information.

[0081] In operation S430, based on the abnormal road condition information, voice broadcast information corresponding to the abnormal road condition information is determined.

[0082] In operation S440, a voice broadcast instruction is generated based on the position relationship between the real-time position information and the target area information.

[0083] In operation S450, based on the voice announcement instruction, the passenger information system is controlled to announce the voice corresponding to the voice announcement information.

[0084] According to an embodiment of the present disclosure, the target area information may be sent by a ground control device, the target area information may be information of a target area located on the route of a target train in motion and which the target train has not yet reached, and the target area may be an area used for voice broadcasting by the target train.

[0085] According to the embodiments of the present disclosure, the target area range corresponding to the target area information can be adjusted based on the abnormal road condition information, so as to obtain the target area information. Due to different abnormal road condition information, the target area range corresponding to the target area information can be adjusted.

[0086] According to the embodiments of the present disclosure, the voice broadcast information corresponding to the abnormal road condition information can be determined based on different abnormal road condition information. For example, when the abnormal road condition information is a bumpy road condition, the voice broadcast information corresponds to the bumpy road condition. For another example, when the abnormal road condition information is a broken rail, the voice broadcast information corresponds to the broken rail.

[0087] According to an embodiment of the present disclosure, when the position relationship representation is that the real-time position of the train is within the target area, a voice broadcast instruction may be generated.

[0088] According to an embodiment of the present disclosure, a voice corresponding to the voice broadcast information can be broadcast based on a voice broadcast instruction. If the real-time position of the train does not reach the target area, no voice broadcast instruction is generated, and thus the voice broadcast information corresponding to the abnormal road condition information will not be broadcast.

[0089] According to the embodiments of the present disclosure, based on the abnormal road condition information, the received target area information can be adjusted to obtain the target target area information. When the real-time position of the train is within the target target area, a voice broadcast instruction can be generated. Based on the abnormal road condition information, voice broadcast information corresponding to the abnormal road condition information can be generated. Based on the voice broadcast instruction, the voice corresponding to the voice broadcast information is broadcast, thereby improving the flexibility of the voice broadcast position and the accuracy of the voice broadcast information.
