The pantograph at the charging station can then connect to the rail vehicle's current collector to charge the battery. However, errors in power transmission for charging demands can occur in related technologies, leading to low charging efficiency. Summary of the Invention

[0023] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0024] This application provides a charging system, see [link to relevant documentation]. Figure 1 The charging system includes: a rail vehicle 10, charging equipment 20, and a control center (also known as a signaling system) 30 for the rail vehicle. Figure 1 As shown, the rail vehicle 10, the charging equipment 20, and the control center 30 establish communication connections with each other.

[0025] Figure 2 This is a structural schematic diagram of a rail vehicle provided in an embodiment of this application. (Combined with...) Figure 2 and Figure 3 It can be seen that the rail vehicle 10 includes: a vehicle controller 100, a battery 110, and multiple current collectors 120. Figure 2 It shows n current collectors (n is an integer greater than 1), a battery management module 130, a communication module 140 corresponding to each current collector 120, and a power distribution module 150.

[0026] The vehicle controller 100 controls and manages the rail vehicle, controlling it based on its direction of travel, speed, and operating mode, and monitoring its status. The battery 110 supplies power to the rail vehicle and is connected to both a current collector 120 and a battery management module 130. The current collector 120 connects to a charging device 20 to charge the battery 110 when the rail vehicle needs charging. The battery management module 130 manages and controls the charging and discharging of the battery 130.

[0027] Each communication module 140 provides wireless communication connectivity. Furthermore, each communication module 140 can be connected to a corresponding current collector 120, vehicle controller 100, and battery management module 130. The power distribution module 150 is connected to both the battery 110 and the vehicle controller 100, and manages the power distribution to various components of the rail vehicle (such as the communication module 120), i.e., it can control the battery 110 to supply or de-energize power to each component. In addition, the power distribution module 150 can monitor the power supply status of each component and feed it back to the vehicle controller 100.

[0028] In the embodiments of this application, see Figure 3 The rail vehicle has multiple carriages. Figure 3Four carriages are shown. At least two carriages (e.g., each carriage) may be equipped with two current collectors 120. During the charging of the rail vehicle, one of these current collectors 120 can be aligned and connected to the charging pantograph of the charging station where the rail vehicle is located to obtain power. Each current collector 120 includes a first electrode plate, a second electrode plate, and a third electrode plate arranged sequentially along the width direction X of the rail vehicle. The polarity of the first electrode plate and the third electrode plate are opposite to the polarity of the second electrode plate. For example, the polarity of the first electrode plate and the third electrode plate may both be negative, while the polarity of the second electrode plate may be positive.

[0029] Because the carriage is equipped with two current collectors 120, it ensures that one current collector on the carriage can align with the charging pantograph of the charging station regardless of whether the pantographs of the multiple charging positions in the charging station are arranged differently, or even if the pantographs of the multiple charging positions are arranged in the same way, and regardless of whether the rail vehicle enters the charging station in the first or second direction. This improves the charging flexibility and convenience of the rail vehicle while ensuring charging capability. Furthermore, each current collector corresponds to a communication module, ensuring effective connection between the current collector and the corresponding communication module. The first direction is opposite to the second direction.

[0030] Understandably, different arrangements of the pantographs in multiple charging stations can reduce the charging cost of the charging equipment while still being able to charge rail vehicles traveling in different directions.

[0031] In this embodiment, the charging device 20 is located in a charging station and includes a charging controller, a charging pantograph, and a communication module. The charging controller controls the charging pantograph to charge the rail vehicle 10. The communication module provides wireless communication connectivity. Optionally, the charging station can be located at a platform, depot, or parking lot, etc.

[0032] The signaling system 30 can be used for scheduling and controlling rail vehicles, such as controlling the operation of rail vehicles, controlling the charging of rail vehicles, or controlling the sleep mode of rail vehicles. Optionally, the signaling system 30 can be an automatic train supervision (ATS), an automatic train protection (ATP) system, or an automatic train operation (ATO) system, etc.

[0033] This application provides a control method for a rail vehicle, which is applied to the vehicle controller of the rail vehicle. The rail vehicle includes multiple current collectors and a communication module corresponding to each current collector. See also... Figure 4 The method includes:

[0034] Step 201: Receive the first charging command.

[0035] Once the rail vehicle is positioned in the charging station's charging bay, the signaling system can send a first charging command to the rail vehicle via the communication connection with the rail vehicle. The rail vehicle can then receive this first charging command.

[0036] Step 202: In response to the first charging command, determine the target current collector to be charged from the plurality of current collectors.

[0037] The target current collector is one of the two current collectors installed on the rail vehicle's car after the rail vehicle is parked at the charging station, and that can be aligned with the charging pantograph of the charging station.

[0038] Step 203: Control the target communication module corresponding to the target current collector to turn on, and control the communication modules other than the target communication module to turn off.

[0039] Since all communication modules are usually turned off before the rail vehicle is charged, the vehicle controller only needs to control the power distribution module of the rail vehicle to supply power to the target communication module to achieve the effect of controlling the target communication module to turn on and controlling the other communication modules to turn off.

[0040] In this embodiment, after the target communication module is activated, the battery management module of the rail vehicle can send the battery's power requirement to the charging device through the target communication module, so that the charging device can charge the rail vehicle based on the power requirement. This power requirement can change in real time.

[0041] In addition, the current drawer corresponding to the target communication module can also send the current and voltage of the current drawer to the charging device through the target communication module, so that the charging device can adjust the charging parameters based on the operating parameters, so that the current and voltage of the current drawer are within the allowable range.

[0042] In summary, this application provides a control method for a rail vehicle, which includes multiple current collectors and communication modules corresponding to each current collector. Upon receiving a first charging command, the method can determine the target current collector from among the multiple current collectors, and control the target communication module corresponding to the target current collector to start, and the other communication modules to shut down. This avoids the problem of communication interference caused by all communication modules starting up, thus preventing the charging equipment from failing to receive the power demand of the rail vehicle's battery due to communication interference, and instead charging the rail vehicle according to the minimum power demand, thereby effectively improving the charging efficiency of the rail vehicle.

[0043] Figure 5 This is a flowchart illustrating another control method for a rail vehicle provided in an embodiment of this application. This method can be applied to the vehicle controller of a rail vehicle. The rail vehicle includes multiple current collectors and a communication module corresponding to each of the multiple current collectors. See also... Figure 5 The method may include:

[0044] Step 301: Receive the first charging command.

[0045] Once a rail vehicle is positioned in the charging station's charging bay, the signaling system can detect whether the vehicle meets the charging requirements. If the signaling system determines that the vehicle meets the charging requirements, it can send a first charging command to the vehicle.

[0046] The charging conditions may include: the rail vehicle is stationary, the rail vehicle is accurately parked in the charging position, and the power distribution module and charging management module of the rail vehicle are working normally.

[0047] Understandably, once the rail vehicle's controller is parked at the charging station, it can establish a wireless communication connection with the signaling system. Correspondingly, the controller can receive the first charging command from the signaling system through this wireless communication connection. The communication technology used for this wireless communication connection can be Long-Term Evolution in Unlicensed Spectrum (LTE-U).

[0048] Step 302: In response to the first charging command, detect whether the rail vehicle is stationary.

[0049] Charging can only be performed when the rail vehicle is stationary to ensure high charging safety. Therefore, upon receiving the first charging command, the rail vehicle can detect whether it is stationary in response to the command. If the vehicle controller determines that the rail vehicle is stationary, step 303 can be executed. If the vehicle controller determines that the rail vehicle is not stationary, step 302 can be executed.

[0050] In this embodiment, a speed sensor connected to the vehicle controller can be installed on the rail vehicle. This speed sensor can collect the vehicle's speed and upload it to the vehicle controller. Then, if the vehicle controller determines that the speed is 0, it can determine that the rail vehicle is stationary.

[0051] Step 303: Determine the target current collector to be powered from multiple current collectors.

[0052] The target current collector is one of the two current collectors installed on the rail vehicle's car after the rail vehicle is parked at the charging station, and that can be aligned with the charging pantograph of that charging station. In other words, the arrangement of the identified multiple target current collectors is consistent with the arrangement of the charging pantographs used to charge the rail vehicle.

[0053] In this embodiment, the vehicle controller of the rail vehicle can determine a target current collector from multiple current collectors based on the direction in which the rail vehicle enters the charging station. This direction can be a first direction or a second direction. Determining the target current collector from multiple current collectors means that, for each car, a target current collector that can be aligned with the pantograph of the charging station where the rail vehicle is located is selected from the two current collectors installed on that car.

[0054] In one possible implementation, the pantographs of multiple charging stations in the charging station are arranged in the same way. In this case, the vehicle controller can directly determine the target current collector from multiple current collectors based on the direction the rail vehicle is approaching. Specifically, the vehicle controller can pre-store a correspondence between directions and current collectors. The vehicle controller can determine the current collector corresponding to the direction the rail vehicle is approaching from this correspondence as the target current collector.

[0055] This correspondence records the identifier of each current feeder. This identifier can be used to uniquely identify a current feeder among multiple current feeders. For example, the identifier can be the sequence number of the current feeder among multiple current feeders.

[0056] It is understandable that each charging station includes multiple pantographs, and the multiple pantographs of any two charging stations correspond one-to-one. The pantographs of any two charging stations are arranged in the same way, which means that the distance between any two pantographs in one charging station is equal to the distance between the corresponding two pantographs in the other charging station.

[0057] For example, see Figure 6 The charging track has two charging positions. The first charging position includes charging bows a1, b1, c1, and d1 arranged in sequence. The second charging position includes charging bows a2, b2, c2, and d2 arranged in sequence. The distance between charging bows a1 and b1 is equal to the distance between charging bows a2 and b2. The distance between charging bows b1 and c1 is equal to the distance between charging bows b2 and c2. The distance between charging bows c1 and d1 is equal to the distance between charging bows c2 and d2.

[0058] In this embodiment, the rail vehicle has an input device connected to the vehicle controller. Operators can input the rail vehicle's direction of travel through this input device, and the vehicle controller can correspondingly acquire this direction of travel through the input device. The input device can be a display screen or a voice acquisition device.

[0059] Alternatively, the signaling system can send the direction of entry to the vehicle controller. The vehicle controller can then acquire this direction of entry. The signaling system may also include an input device through which the direction of entry can be acquired. Alternatively, a first RFID tag is installed at one end of the rail vehicle, and a second RFID tag is installed at the other end. This one end can be either the front or rear of the vehicle, and the other end can be the other of the front and rear. A reader / writer can be installed at the charging station. The signaling system can determine the direction of entry of the rail vehicle based on the order in which the reader / writer communicates with the first and second RFID tags.

[0060] Specifically, assuming that in the first direction, the first RFID tag passes the reader first, followed by the second RFID tag, then if the signal system determines that the reader communicates with the first RFID tag first and then with the second RFID tag, the direction of entry can be determined to be the first direction. If the signal system determines that the reader communicates with the second RFID tag first and then with the first RFID tag, the direction of entry can be determined to be the second direction.

[0061] In another possible implementation, at least two of the charging stations have different charging pantograph arrangements. Two charging stations having the same charging pantograph arrangement means that the distance between at least two charging pantographs in one charging station is not equal to the distance between the corresponding two charging pantographs in the other charging station. For example, see... Figure 7 The first charging row on the charging track includes charging bows a3, b3, c3, and d3 arranged in sequence; the second charging row includes charging bows a4, b4, c4, and d4 arranged in sequence. The distance between charging bows a3 and b3 is not equal to the distance between charging bows a4 and b4. The distance between charging bows c3 and d3 is equal to the distance between charging bows c4 and d4.

[0062] At this point, the vehicle controller can determine the target current collector from multiple current collectors based on the direction in which the rail vehicle enters the charging station and the arrangement of the pantographs in the charging column where the rail vehicle is located.

[0063] Specifically, the vehicle controller can pre-store the correspondence between current collectors and their changing directions and arrangements. The vehicle controller can then identify the current collectors that correspond to the direction of the rail vehicle's entry and the arrangement of the pantographs in the charging station where the rail vehicle is located as the target current collectors.

[0064] The rail vehicle can pre-store the pantograph arrangement of each charging station's charging bay. Alternatively, the signaling system can send the pantograph arrangement direction of the charging bay where the rail vehicle is located to the vehicle controller via a wired communication connection with the rail vehicle.

[0065] Step 304: Control the target communication module corresponding to the target current collector to turn on, and control the communication modules other than the target communication module to turn off.

[0066] In this embodiment, for any communication module, if the vehicle controller requires the communication module to be turned on, it can supply power to the communication module. If the vehicle controller requires the communication module to be turned off, it can stop supplying power to the communication module. Since the communication modules corresponding to the current collectors are usually turned off before the rail vehicle is charged, the vehicle controller only needs to supply power to the target communication module to achieve the effect of controlling the target communication module to be turned on and controlling the other communication modules to be turned off.

[0067] In rail vehicles, the power distribution module typically manages the power supply to various components. Therefore, the vehicle controller can send a start command to the power distribution module for the target communication module. The power distribution module can then respond to this start command by supplying power to the target communication module, thereby activating it.

[0068] In other words, for a communication module that needs to be started, the vehicle controller can send a start command to the power distribution module to instruct the power distribution module to supply power to the communication module in order to start the communication module.

[0069] For communication modules that do not require activation, the vehicle controller will not send an activation command to the power distribution module. Consequently, the power distribution module will not supply power to the communication module, and the communication module will therefore be unable to activate.

[0070] Optionally, after the power distribution module supplies power to the target communication module, it can also upload a signal to the vehicle controller to indicate successful power supply. Upon receiving this signal, the vehicle controller can detect whether the target communication module has started successfully and whether other communication modules have been successfully shut down. If the vehicle controller determines that the target communication module has started successfully and other communication modules have been successfully shut down, it can control the rail vehicle to begin charging. If the vehicle controller determines that the target communication module has failed to start, and / or that other communication modules have failed to shut down, it can terminate the operation and report a fault.

[0071] In this embodiment, after the target communication module is successfully started, it can establish a connection with the communication module of the charging device. Then, the battery management module of the rail vehicle can send the battery's power requirement to the charging device through the target communication module. This power requirement is used by the charging device to charge the rail vehicle. That is, the charging device can charge the rail vehicle based on this power requirement.

[0072] In addition, the current drawer corresponding to the target communication module can also send the current and voltage of the current drawer to the charging device through the target communication module, so that the charging device can adjust the charging parameters based on the operating parameters, so that the current and voltage of the current drawer are within the allowable range.

[0073] In this embodiment, the vehicle controller can send a second charging command to the battery management module, and the battery management module can respond to the second charging command by sending the power requirements of the rail vehicle to the charging equipment through the target communication module.

[0074] Understandably, before charging, the charging device can control the pantograph of the charging device to lower (i.e., lower the pantograph) to connect with the target current collector. After charging is completed, the charging device can control the pantograph to rise (i.e., raise the pantograph).

[0075] It is understood that the order of steps in the control method for rail vehicles provided in this application can be appropriately adjusted, and steps can be added or removed as needed. For example, step 302 can be deleted as appropriate. Any variations that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the protection scope of this application, and therefore will not be elaborated further.

[0076] In summary, this application provides a control method for a rail vehicle, which includes multiple current collectors and communication modules corresponding to each current collector. Upon receiving a first charging command, the method can determine the target current collector from among the multiple current collectors, and control the target communication module corresponding to the target current collector to start, and the other communication modules to shut down. This avoids the problem of communication interference caused by all communication modules starting up, thus preventing the charging equipment from failing to receive the power demand of the rail vehicle's battery due to communication interference, and instead charging the rail vehicle according to the minimum power demand, thereby effectively improving the charging efficiency of the rail vehicle.

[0077] This application provides a vehicle controller, in which the rail vehicle includes multiple current collectors and a communication module corresponding to each current collector. See also Figure 8 The vehicle controller 100 includes a processor 101. The processor 101 is used for:

[0079] In response to a first charging command, the target current collector to be charged is determined from a plurality of current collectors;

[0081] Optionally, the processor 101 can be used for:

[0082] In response to the first charging command, the target current collector to be charged is determined from multiple current collectors according to the direction of the rail vehicle entering the charging station.

[0083] Optionally, a first RFID tag is installed at one end of the rail vehicle, a second RFID tag is installed at the other end of the rail vehicle, and a reader / writer is installed at the charging station. The processor 101 can also be used for:

[0084] The direction of entry is received, which is obtained based on the order in which the reader communicates with the first RFID tag and the second RFID tag.

[0085] Optionally, the charging station for the rail vehicle has multiple charging rows, with at least two charging rows having different pantograph arrangements. The processor 101 can be used for:

[0086] Based on the direction the rail vehicle enters the charging station and the arrangement of the pantographs in the charging column where the rail vehicle is located, the target current collector to be powered is determined from multiple current collectors.

[0087] Optionally, the processor 101 can be used for:

[0088] In response to the first charging command, if the rail vehicle is stationary, the target current collector to be charged is determined from a plurality of current collectors.

[0089] Optionally, the processor 101 can be used to: send a start command for the target communication module to the power distribution module of the rail vehicle, the start command being used to instruct the power distribution module to supply power to the target communication module so that the target communication module can be started.

[0090] Optionally, the processor 101 can also be used to: send a second charging command to the battery management module of the rail vehicle, the second charging command being used to instruct the battery management module to send the power demand of the rail vehicle to the charging device through the target communication module, the power demand being used to charge the rail vehicle by the charging device.

[0091] In summary, this application provides a vehicle controller for a rail vehicle, which includes multiple current collectors and communication modules corresponding to each current collector. Upon receiving a first charging command, the vehicle controller can identify the target current collector from among the multiple current collectors and control the target communication module corresponding to the target current collector to start, and the other communication modules to shut down. This avoids the problem of communication interference caused by all communication modules starting up, thus preventing the charging equipment from failing to receive the power demand of the rail vehicle's battery due to communication interference, and instead charging the rail vehicle according to the minimum power demand, thereby effectively improving the charging efficiency of the rail vehicle.
