[0056] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0057] The core of the present application is to provide a method, device, medium and rail train for controlling an electric whistle of a rail train.

[0058] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0059] In actual operation, the traditional manual control whistle method has many problems. On the one hand, the driver may fail to blow the whistle in time due to distraction, delayed reaction, etc., affecting driving safety; on the other hand, manual control is difficult to accurately distinguish between day and night and adjust the whistle volume, which often leads to excessive whistle volume at night, disturbing residents' rest. This application does not limit the specific type of rail trains, and is applicable to all rail transit vehicles that use electric whistles as warning devices, including subways, trains, high-speed railways, etc.

[0060] In order to solve these problems, the present invention provides a method for controlling an electric horn of a railway train. Figure 1 A flow chart of a method for controlling an electric horn of a railway train is provided in an embodiment of the present application, such as Figure 1 As shown, including:

[0061] S11: Obtain vehicle operation information, line information, positioning information and current day and night information of the current train;

[0062] S12: judging whether it is necessary to honk the horn according to the vehicle operation information, or judging whether the vehicle is currently in a range where the horn needs to be honk according to the route information and positioning information;

[0063] S13: If a whistle is required, determine the whistle volume according to the day and night information;

[0064] S14: Determine a corresponding whistle display mode according to the current whistle-requiring scenario and whistle volume;

[0065] S15: Sending a whistle instruction to the electric whistle controller according to the whistle indication mode.

[0066] This embodiment is mainly used to automatically and accurately control the train's whistle behavior according to the real-time running status of the train and the surrounding environment.

[0067] Vehicle operation information usually includes the train's speed, acceleration, braking status, etc., which is used to determine whether the train is in an operating mode that requires whistle blowing, such as normal driving, emergency braking, reverse start, etc., and can be obtained through the train's own sensors and control systems.

[0068] The line information includes data on the railway line along which the train is traveling, such as specific areas on the line, such as residential areas, school areas, etc., and the locations of curves, crossings, bridges, tunnels, etc., which are used to determine which sections of the line need to sound the whistle and the frequency and volume of the whistle.

[0069] Day and night information is used to distinguish whether it is day or night. The day and night can be distinguished by obtaining the ambient light intensity in real time or the system's built-in time judgment, so as to adjust the horn volume according to regulations.

[0070] Positioning information: Use satellite positioning systems such as the Global Positioning System (GPS) and Beidou or positioning signals on the track to accurately obtain the current position of the train, providing an accurate geographical reference for determining whether the whistle needs to be sounded.

[0071] Determine whether the horn needs to be sounded based on the vehicle operation information, that is, different types of horns are sounded when the vehicle starts, brakes, or reverses; or determine whether the current range requires horn sounding based on line information and positioning information, and determine whether the vehicle has reached the range where the horn needs to be sounded during driving. For example, when a train approaches a crossing or a bridge, the system will determine that the horn needs to be sounded to alert surrounding personnel. The distance from the target location to be considered as entering the horn range can be determined based on actual needs. The range can be different for different scenarios, and the horn range can also be different at different times. For example, the horn range at night can be larger than the horn range during the day to avoid the problem of untimely response due to poor lighting conditions.

[0072] If the horn is required, the horn volume is determined based on the day and night information. The horn volume is automatically adjusted based on the day and night information. During the day, the system may set a higher horn volume to ensure driving safety; at night, in order to reduce noise interference to surrounding residents, the system will reduce the horn volume accordingly. The specific volume decibel is set according to regulations.

[0073] The corresponding sounding mode is determined according to the current scene where the whistle needs to be blown and the whistle volume. According to the whistle volume and route information (such as train operation plan, line characteristics, etc.), the current whistle scene and the corresponding sounding mode are comprehensively judged. For example, a long whistle may be needed to remind you before entering the station, while a short whistle may be needed when passing through the crossing to avoid scaring pedestrians. The specific sounding modes for different scenes are set according to actual needs or regulations.

[0074] According to the determined whistle mode, a specific whistle instruction is sent to the whistle controller through the train network. After receiving the instruction, the whistle controller will control the whistle to sound according to the specified volume, frequency and duration.

[0075] Through the electric whistle control method for rail trains provided in the embodiment of the present application, the vehicle operation information, line information, positioning information and day and night information of the current train are obtained; whether the whistle needs to be sounded is determined according to the vehicle operation information, or whether the current range of the whistle needs to be sounded is determined according to the line information and positioning information; if the whistle needs to be sounded, the whistle volume is determined according to the day and night information; the corresponding sounding mode is determined according to the current scene where the whistle needs to be sounded and the whistle volume; and a whistle instruction is issued to the electric whistle controller according to the sounding mode. The present application determines whether the vehicle is in an operating state where the whistle needs to be sounded through the vehicle operation information, and preliminarily determines whether it has entered the whistle range according to the line information and positioning information; if the whistle needs to be sounded, the whistle volume is further determined according to the day and night information, and different scenes where the whistle needs to be sounded correspond to different sounding modes, and specific high and low frequencies are automatically controlled. The whistle volume is automatically adjusted according to the day and night information to reduce noise interference to surrounding residents, meet environmental protection requirements, reduce the driver's manual operation of the whistle, avoid misoperation or missed operation caused by human factors, and improve driving safety.

[0076] According to the above embodiment, in a specific embodiment, obtaining the day and night information at the current moment includes:

[0077] Receive light brightness information sent by a photosensitive sensor installed on the top of the train;

[0078] Determine the day or night information of whether it is currently daytime or nighttime according to the light illumination information;

[0079] If the light sensor fails, determine the current sunrise and sunset times based on the positioning information and the current date;

[0080] The day and night information is determined based on the sunrise and sunset times to determine whether the current moment is daytime or nighttime.

[0081] A photosensitive sensor is a device that can sense the brightness of external light. It is usually installed on the top of a train to accurately measure the light intensity of the external environment. The photosensitive sensor sends the perceived light brightness information to the train's control system to determine the day and night conditions.

[0082] After receiving the light brightness information, the train control system will use a preset threshold or algorithm to determine whether the current light brightness reaches the daytime standard. If the light brightness is higher than the preset daytime threshold, it is determined to be daytime; otherwise, it is determined to be nighttime.

[0083] If the light sensor fails, the current sunrise and sunset time is determined based on the positioning information and the current date. In some cases, the light sensor may fail and not work properly. The train control system uses GPS and other positioning devices to obtain the current geographic location and date information. Based on the geographic location and date, the control system can query or calculate the sunrise and sunset time of the day.

[0084] After determining the sunrise and sunset times, compare the current time with the sunrise and sunset times. If the current time is after sunrise and before sunset, it is determined to be daytime; if it is after sunset and before sunrise the next day, it is determined to be nighttime.

[0085] Through the above steps, even in the event of a photosensitive sensor failure, the train control system can accurately obtain the current day and night information, thereby ensuring that the train whistles at an appropriate volume at an appropriate time, reducing the impact on surrounding residents.

[0086] According to the above embodiment, in a specific embodiment, obtaining the vehicle operation information of the current train includes:

[0087] Obtain the direction handle position information, train speed information, and traction information in the driver's cab;

[0088] Determine the running direction of the vehicle according to the position information of the steering handle;

[0089] Determine vehicle status based on train speed information and traction information;

[0090] The vehicle operation information is determined according to the vehicle operation direction and vehicle status.

[0091] The current handle position is obtained from the direction handle in the driver's cab to indicate the direction of the train. When the direction handle is pushed forward from a static position, it usually means that the driver intends to start the train. When the direction handle is pulled backward from a static position, it usually means that the driver intends to reverse the train.

[0092] The current train speed is obtained through the speed sensor or related equipment on the train to determine the train running status.

[0093] The current traction data is obtained through the train power system or related sensors to reflect the power output status of the train.

[0094] The vehicle's running direction is determined based on the direction handle position information, and the position information of the direction handle is used to determine whether the train is running forward or backward, or is at a standstill.

[0095] If the train speed increases from 0, combined with the direction handle position information, it can be determined that the train is starting. If the train speed changes from a positive value to a negative value, and the direction handle position information indicates reverse travel, it can be determined that the train is reverse travel. If the train speed gradually decreases, but the direction handle position information still indicates forward travel, it can be determined that the train is decelerating. When the direction handle indicates forward travel, the train speed increases, and the traction information is positive and gradually increases, the train is in a starting acceleration state. When the direction handle indicates reverse travel, the train speed decreases, and the traction information is negative and gradually increases, the train is in a reverse acceleration state. Regardless of the direction handle position, when the train speed decreases and the traction information becomes negative or decreases to close to 0, the train is in a deceleration braking state.

[0096] Through the comprehensive application of the above steps and logic, the vehicle's running status, starting, reversing, deceleration, etc. can be determined more accurately based on the combination of the direction handle position information, train speed information, and traction information in the driver's cab. The above only provides a basic judgment logic, and more complex factors and special circumstances may need to be considered in actual applications.

[0097] Provides comprehensive vehicle running direction and vehicle status to form complete vehicle running information. This includes key parameters such as the train's running direction (forward, reverse or stationary), current speed, acceleration or deceleration.

[0098] Table 1 is a table of whistle sounding methods provided in an embodiment of the present application. As shown in Table 1, different whistle-blowing scenarios require different whistle-blowing methods. The first three methods are automatically judged through the above-mentioned technical solution of the present application and the whistle is sounded in time.

[0099] Table 1: Whistle sounding method table

[0100] According to the above embodiment, in a specific embodiment, obtaining the line information of the current train includes:

[0101] Obtain the route information of the current train and obtain the route information table through the on-board antenna;

[0102] According to the route information, the line information of the current train operation is obtained from the line information table;

[0103] The route information is sent to the vehicle driving dynamics control system to identify the location where the horn needs to be sounded and the corresponding kilometer information mark in the route information table.

[0104] Through the train operation management system or related equipment, the route information of the current train is obtained. The route information usually includes the train's starting station, terminal station, and the stations and sections it passes through.

[0105] The train is equipped with an onboard antenna to receive ground signals or wirelessly transmitted data. Through the onboard antenna, the train can receive and store the route information table. The route information table is a detailed data set that contains all possible operating routes and their related positioning information.

[0106] According to the route information, the route information of the current train is extracted from the route information table, and the obtained route information is matched with the route information table to extract the route information corresponding to the current train route. This route information may include the specific direction of the route, the location of the whistle sign along the way, and key locations such as crossings, bridges, and tunnels.

[0107] The extracted line information is sent to the train's vehicle dynamics control system, which is responsible for real-time monitoring of the train's operating status and making corresponding control adjustments based on the received line information.

[0108] Identify the locations where the whistle needs to be blown and the corresponding kilometer information marks in the line information table, and identify the specific locations where the train needs to blow the whistle during its travel according to the whistle mark location information in the line information table. At the same time, the system will also record the kilometer information marks corresponding to these locations so that the whistle command can be issued in time when the train approaches these locations.

[0109] Through the above steps, the train can accurately obtain and apply the current line information, ensure timely warnings at key locations where the whistle needs to be sounded, and improve the safety and efficiency of train operation.

[0110] In a specific embodiment, judging whether the vehicle is currently in a range where the horn needs to be sounded based on the route information and the positioning information includes:

[0111] Control the vehicle's driving dynamics control system to compare the positioning information with the kilometer information mark in the route information in real time;

[0112] Determine whether the preset whistle range is reached based on the positioning information and the kilometer information mark;

[0113] If so, it is determined that the vehicle has entered the range where the horn needs to be sounded.

[0114] The vehicle dynamic control system compares the positioning information with the kilometer information mark in the line information in real time. The train is equipped with a positioning system (such as GPS, Beidou, etc.) and a vehicle dynamic control system. The positioning system provides the current position information of the train (i.e. positioning information) in real time, while the vehicle dynamic control system stores the kilometer information mark obtained from the line information table.

[0115] The vehicle dynamics control system is programmed to compare the positioning information and kilometer information marks in real time to determine the relative relationship between the train's current position and specific locations predefined in the line information (such as whistle marks).

[0116] The train determines whether it has entered the preset whistle range based on the positioning information and the kilometer information mark. The preset whistle range is a distance range set for specific locations (such as crossings, bridges, tunnel entrances, etc.) in the route information table. When the train approaches these locations, it needs to sound the whistle to alert the surrounding environment and pedestrians.

[0117] The vehicle dynamics control system determines whether the train is currently within a preset whistle range by comparing the positioning information and the kilometer information mark. This usually involves calculating the distance between the train's current position and a specific location and comparing that distance with the preset whistle range.

[0118] If the vehicle dynamics control system determines that the train's current position is within a preset whistle range, the system will determine that the train has entered the range where the whistle needs to be blown. Subsequently, the system will trigger the whistle command and send a warning signal through the train's whistle device to ensure that the train can promptly alert the surrounding environment and pedestrians when approaching a specific location.

[0119] Through the above steps, the train can accurately determine whether it is necessary to sound the whistle based on real-time positioning information and preset line information, thereby improving the safety and reliability of train operation.

[0120] According to the above embodiment, in a specific embodiment, it also includes:

[0121] An emergency trigger command is received;

[0122] Sending a whistle command to the electric whistle controller according to the whistle mode corresponding to the emergency trigger command;

[0123] If the current whistle instruction is to continue whistling, when the reset instruction is received, a stop whistle instruction is sent to the electric whistle controller.

[0124] As shown in Table 1, the last three situations are actively triggered by the driver's observation. The fourth and fifth situations stop automatically, while the sixth situation requires continuous honking. The driver judges that the horn needs to be stopped based on observation and actively triggers the horn to stop, thus realizing active control in special scenarios.

[0125] According to the above embodiment, in a specific embodiment, after issuing a whistle instruction to the electric whistle controller according to the whistle indication mode, the method further includes:

[0126] Send out voice prompts for the current horn-requiring scenario;

[0127] The trigger button corresponding to the whistle mode is displayed on the manual whistle triggering interface;

[0128] When the electric whistle controller fails to sound, a trigger command from a trigger button is received;

[0129] Send a whistle command to the electric whistle controller according to the trigger command.

[0130] In a more perfect embodiment, the train whistle control system not only sends a whistle instruction to the electric whistle controller according to the whistle indication mode, but also combines voice prompts, interface instructions and manual triggering functions to ensure that when the electric whistle automatic control system fails, the driver can still manually trigger the whistle. For example, the last three situations in Table 1 are active triggering by driver observation.

[0131] When the system determines that the horn needs to be honked based on positioning information, route information or emergency trigger instructions, it will issue specific honking instructions to the electric horn controller according to the preset honking methods (such as short honking, continuous honking, intermittent honking, etc.). In order to enhance the driver's understanding of the current honking scenario, the system will issue voice prompts corresponding to the current honking scenario through the vehicle voice system at the same time as issuing the honking instruction. For example, "The horn will be honked at the intersection ahead" or "Slow down and honk."

[0132] The train cab is equipped with a manual whistle triggering interface, which displays the trigger buttons corresponding to different whistle modes. When the system issues a whistle command, the trigger button corresponding to the current whistle mode will be highlighted or flashed on the interface so that the driver can quickly find and trigger it when needed.

[0133] When the electric horn controller fails to sound the horn, it receives the trigger command from the trigger button. Although the electric horn control system is usually highly reliable, in some extreme cases (such as equipment failure, power outage, etc.), the electric horn controller may fail and fail to respond to the system's horn command. In order to deal with this situation, the system is designed with a manual trigger function. When the electric horn controller fails to sound the horn, the driver can issue a horn command by pressing the trigger button on the manual horn trigger interface.

[0134] After receiving the trigger command from the driver through the trigger button, it will immediately send a whistle command to the electric whistle controller and try to manually start the electric whistle to sound the whistle. If the electric whistle controller still fails to respond, the system may further take other safety measures, such as deceleration and parking, to ensure the safety of train operation.

[0135] Through the above steps, the system reliability and flexibility are improved through voice prompts, interface instructions and manual triggering functions. Even if the electric whistle automatic control system fails, the driver can quickly trigger the whistle manually to ensure the safety and reliability of train operation.

[0136] In the event that the electric horn controller fails to sound the horn, the driver can manually trigger the horn by pressing the trigger button on the manual horn trigger interface. The system monitors the status of these trigger buttons in real time, and once it detects that a button is pressed, it will receive and process the trigger command.

[0137] If the whistle still fails to sound even after manual triggering, the system should immediately take other safety measures to ensure the safety of the train. This may include slowing down, stopping, sending an alarm signal to the ground control center, etc., to ensure the safety of the train operation to the greatest extent.
