The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0038] Based on the problems existing in related technologies, this application provides a control method for heavy-haul trains. The method is applied to electronic devices, such as computers and mobile terminals. The mobile terminal may include mobile phones, tablet computers, etc. In some embodiments, the electronic device may be a controller or processor of the heavy-haul train.

[0039] In some embodiments, the electronic device is located within a control system, which includes a dispatch center, a temporary speed limit server, a radio block center, and the electronic device. The dispatch center, temporary speed limit server, radio block center, and electronic device can be wirelessly connected. The electronic device can be an in-vehicle device. Instructions sent by the dispatch center, such as temporary speed limit information, can be transmitted to the electronic device via the temporary speed limit server and the radio block center.

[0040] The control method for heavy-haul trains provided in this application can achieve its functions by having the processor of an electronic device call program code, wherein the program code can be stored in a computer storage medium.

[0041] Example 1

[0042] This application provides a control method for heavy-haul trains. Figure 1 This is a schematic diagram illustrating the implementation process of a control method for heavy-haul trains provided in an embodiment of this application, as shown below. Figure 1 As shown, it includes:

[0043] Step S101: Obtain the current speed of the heavy-haul train at its current position, the temporary speed limit of the speed-limited section ahead of the current position of the heavy-haul train, and the gradient information of the speed-limited section, wherein different gradient information corresponds to different minimum speed limit requirements.

[0044] In this embodiment of the application, the electronic device can be communicatively connected to a speed sensor to obtain the current speed of the heavy-load train at its current position.

[0045] In this embodiment of the application, the electronic device can communicate with the positioning device to determine its current location in real time.

[0046] In this embodiment of the application, the electronic device stores line information in advance, and the line information can be used to determine whether there is a speed limit section ahead of the current position of the heavy-load train.

[0047] In some embodiments, temporary speed limits in speed-limited sections may be planned speed limits caused by construction, severe weather, or maintenance, or sudden speed limits caused by natural disasters or equipment failures.

[0048] In this embodiment of the application, users can set temporary speed limits through the dispatch center or directly through electronic devices.

[0049] When a temporary speed limit is set using a dispatch center, the dispatch center obtains the setting information and sends the setting information to a temporary speed limit server. The setting information is used to set a temporary speed limit. The temporary speed limit server sends the temporary speed limit to a radio blocking center. The radio blocking center sends the temporary speed limit to electronic devices.

[0050] In this embodiment, temporary speed limits are set through the dispatch center, so that all trains corresponding to the radio block center area can obtain the temporary speed limits, which simplifies the cumbersome process of sending temporary speed limits to trains via text or IC cards in related technologies.

[0051] In this embodiment of the application, the dispatch center is used to obtain setting information and send the setting information to the temporary speed limit server. The setting information is used to set a temporary speed limit. The temporary speed limit server sends the temporary speed limit to the radio blocking center. The radio blocking center is used to send the temporary speed limit to the electronic device.

[0052] In this embodiment, the dispatch center can obtain user settings information, which is used to set a first temporary speed limit corresponding to a first gradient and a second temporary speed limit corresponding to a second gradient, wherein the first gradient is less than the second gradient, and the first temporary speed limit is less than the second temporary speed limit. The settings information is then sent to the electronic device, enabling the electronic device to obtain the temporary speed limit.

[0053] In some embodiments, when a temporary speed limit is set directly using an electronic device, the electronic device can obtain the user's setting information, which is used to set a first slope information corresponding to a first temporary speed limit and a second slope information corresponding to a second temporary speed limit, wherein the first slope is less than the second slope and the first temporary speed limit is less than the second temporary speed limit; and the setting information is stored.

[0054] In this embodiment of the application, the first slope is less than 4‰, the first temporary speed limit is greater than 25 km / h, the second slope is greater than or equal to 12‰, and the second temporary speed limit is greater than or equal to 45 km / h.

[0055] In this embodiment of the application, the temporary speed limit is set according to logical segments, with 5 km / h as one level; when setting the temporary speed limit, the braking performance of heavy-load trains should be considered to avoid the train hitting the braking curve before entering the speed limit segment.

[0056] In some embodiments, when the speed limit section includes an overlapping section of the first speed limit section and the second speed limit section, the magnitude relationship between the third temporary speed limit of the first speed limit section and the fourth temporary speed limit of the second speed limit section can be compared; if the third temporary speed limit is less than the fourth temporary speed limit, the third temporary speed limit is determined as a temporary speed limit; if the fourth temporary speed limit is less than the third temporary speed limit, the fourth temporary speed limit is determined as a temporary speed limit.

[0057] For example, Figure 2 This is a schematic diagram of an overlapping section provided in an embodiment of this application, as shown below. Figure 2 As shown, the first speed limit section has a lateral speed limit of 30 km / h and a mainline speed limit of 20 km / h. Therefore, the overlapping section CE has a temporary speed limit of 20 km / h.

[0058] In this embodiment of the application, the speed-limited section includes: the throat area in front of the station or the station.

[0059] Step S102: Determine the braking performance of the heavy-haul train based on the gradient information.

[0060] In this embodiment of the application, the braking performance of the heavy-haul train can be determined based on the gradient information and the pre-established correspondence. The correspondence includes: a correspondence between a first gradient and a first braking performance, and a correspondence between a second gradient and a second braking performance, wherein the first braking performance is greater than the second braking performance.

[0061] In this embodiment of the application, when the slope information is a first slope, the braking performance is a first braking performance; when the slope information is a second slope, the braking performance is a second braking performance.

[0062] Step S103: Determine the reserved distance based on the current speed, the temporary speed limit, and braking performance.

[0063] In this embodiment of the application, the reserved distance can be calculated based on the current speed, the temporary speed limit, and the braking performance.

[0064] Continuing the example above, the operating speed of trains on the main line in gentle sections (gradient less than 0.4%) of heavy-haul freight railways is approximately 75 km / h. Furthermore, heavy-haul trains should avoid emergency braking and overtaking as much as possible. Therefore, when setting temporary speed limits, the braking distance of the train should be considered to prevent the train from braking due to a sudden temporary speed limit ahead. For example, different allowance distances should be provided for different speed limits depending on whether the driver uses the maximum electric braking or the 60 kPa air braking.

[0065]

[0066] For example, when a train is running on a long downhill slope, different allowance distances may be required for different speed limits, such as:

[0067]

[0068] Step S104: When the heavy-haul train has traveled to the position corresponding to the reserved distance, control the heavy-haul train to brake.

[0069] In this embodiment of the application, control commands can be sent to the braking device of the heavy-haul train to cause the braking device to brake. The braking device may include: an electric braking device and / or an air braking device.

[0070] This application provides a control method for heavy-haul trains. The method acquires the current speed of the heavy-haul train at its current position, the temporary speed limit of the speed-limited section ahead of the train, and the gradient information of the speed-limited section, where different gradient information corresponds to different minimum speed limits. Based on the gradient information, the method determines the braking performance of the heavy-haul train. Based on the current speed, the temporary speed limit, and the braking performance, a reserve distance is determined. When the heavy-haul train reaches the position corresponding to the reserve distance, the method controls the train to brake automatically, thus avoiding the problem of the train braking while hitting the lane line.

[0074] The acquisition module is used to acquire the current speed of the heavy-haul train at its current position, the temporary speed limit of the speed-limited section ahead of the current position of the heavy-haul train, and the gradient information of the speed-limited section, wherein different gradient information corresponds to different minimum speed limit requirements.

[0082] In some embodiments, determining the braking performance of the heavy-haul train based on the gradient information includes:
