Description

Technical Field

[0001] The present invention relates to the technical field of train charging control, and in particular to a reconnection method during train charging, a computer-readable storage medium, a battery manager, and a charging server. Background Art

[0002] Currently, train charging systems primarily utilize plug-in charging, with train-to-ground communication relying on hardwired CAN (Computer Integrated Circuit) cables. Reconnection in the event of a charging system communication failure is performed by the charger sending a handshake signal via the CAN line, with a limit of three reconnections. This reconnection method can only be performed during charging. If an anomaly occurs during the connection between the vehicle and the charger, reconnection is impossible. Therefore, the existing train charging reconnection methods cannot guarantee effective charging reliability. Summary of the Invention

[0003] The present invention aims to at least partially address one of the technical problems in the related art. To this end, one object of the present invention is to provide a reconnection method for train charging that can, in the event of an abnormality in the connection between the train and the charging server, perform an unlimited number of reconnections to ensure normal charging of the train and improve the reliability of train charging.

[0004] A second object of the present invention is to provide another reconnection method when a train is charging.

[0005] A third object of the present invention is to provide a computer-readable storage medium.

[0006] A fourth objective of the present invention is to provide a battery manager.

[0007] A fifth objective of the present invention is to provide a charging server.

[0008] To achieve the above-mentioned purpose, an embodiment of the first aspect of the present invention proposes a reconnection method for charging a train, wherein the train includes a battery manager and a first communication device, the battery manager is connected to the first communication device, and the first communication device is also communicatively connected to the second communication device, and since the charging server is connected to the second communication device, the battery manager and the charging server can be communicatively connected. The reconnection method in this embodiment includes the following steps: when the battery manager receives a charging instruction, it sends a charging request to the charging server through the first communication device; when the battery manager does not receive the charging request reply information sent by the charging server, it continues to receive, wherein the charging request reply information is generated and sent by the charging server when it receives the charging instruction but does not receive the charging request by continuously re-establishing the communication connection between the first communication device and the second communication device.

[0009] In this embodiment, the battery manager is connected to the charging server via a first communication device and a second communication device. When the battery manager receives a charging instruction, it can send a charging request to the charging server via the first communication device. When the battery manager does not receive a charging request reply message sent by the charging server, it continues to receive the charging request reply message, wherein the charging request reply message is sent by the charging server via the second communication device. When the charging server receives a charging instruction but does not receive a charging request sent by the battery manager, it can continuously establish a connection between the first communication device and the second communication device so that when it receives a charging request sent by the battery manager, it can generate a charging request reply message and send it to the battery manager. Therefore, the reconnection method for train charging in the embodiment of the present invention can perform unlimited reconnections when an abnormality occurs in the connection process between the train and the charging server to ensure that the train can be charged normally, thereby improving the reliability of train charging.

[0010] To achieve the above-mentioned purpose, the second aspect of the present invention proposes another reconnection method for train charging, wherein the train includes a battery manager and a first communication device, the battery manager is connected to the first communication device, and the first communication device is also communicatively connected to the second communication device, and since the charging server is connected to the second communication device, the battery manager and the charging server can be communicatively connected. The reconnection method in this embodiment includes the following steps: when the charging server receives a charging instruction, the charging server receives a charging request sent by the battery manager through the second communication device; when the charging server does not receive the charging request, the charging server continuously re-establishes the communication connection between the second communication device and the first communication device until it receives the charging request and generates a charging request reply message; the charging server sends the charging request reply message to the battery manager.

[0011] In this embodiment, the battery manager and the charging server are connected via a first communication device and a second communication device. After receiving the charging instruction, the charging server can receive the charging request sent by the battery manager via the second communication device. If the charging server does not receive the charging request, the communication connection between the second communication device and the first communication device is continuously reestablished until the charging server receives the charging request from the battery manager. Upon receiving the charging request, the charging server generates a charging request reply message, which is then sent to the battery manager based on the charging server. Therefore, the reconnection method for train charging in this embodiment of the present invention can perform unlimited reconnections when an abnormality occurs during the connection process between the train and the charging server to ensure that the train can be charged normally, thereby improving the reliability of train charging.

[0012] To achieve the above-mentioned purpose, an embodiment of the third aspect of the present invention proposes a computer-readable storage medium on which a reconnection program for train charging is stored. When the reconnection program is executed by a processor, the reconnection method for train charging described in the above-mentioned embodiment is implemented.

When the reconnection program is executed by the processor, the reconnection method for train charging in the above-mentioned embodiment is implemented.

[0017] The charging server in this embodiment includes a memory and a processor. The processor executes the reconnection program for train charging stored in the memory. When an abnormality occurs in the connection process between the train and the charging server, it can reconnect an unlimited number of times to ensure that the train can be charged normally, thereby improving the reliability of train charging.

[0027] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0028] The following describes the train charging reconnection method, storage medium, manager, and server according to an embodiment of the present invention with reference to the accompanying drawings.

[0029] The present invention proposes a first reconnection method for charging a train. First of all, it should be noted that the train may include a battery manager and a first communication device, and the charging side may include a charging server and a second communication device, wherein the battery manager can be communicatively connected to the charging server. Specifically, the battery manager on the train is connected to the first communication device, and the charging server is connected to the second communication device. The battery manager and the charging server can be connected to the second communication device through the first communication device.

[0030] Figure 1 4 is a flow chart of a reconnection method during train charging according to an embodiment of the present invention.

[0031] like Figure 1 As shown, the reconnection method of the embodiment of the present invention includes the following steps:

[0032] S10: When the battery manager receives the charging instruction, it sends a charging request to the charging server through the first communication device.

[0033] It should be noted that the charging instruction in this embodiment can be issued through the signal system, and, as Figure 2 As shown, the train in this embodiment may also include an onboard controller, a train control and management system, etc. When the signal system sends a charging instruction to the battery manager, it may first send the charging instruction to the vehicle controller. In this embodiment, the vehicle controller sends the charging instruction to the train control and management system in a transparent manner, and then the train control and management system sends the charging instruction to the battery manager. When the battery manager receives the charging instruction, it may send a corresponding charging request to the charging server through the first communication device. Specifically, the first communication device may be Figure 2 The car CANWiFi shown in the figure, the second communication device can be the charging bow CANWiFi. When the battery manager receives the charging instruction, it can send a charging request to the charging bow CANWiFi through the car CANWiFi. After receiving the charging request, the charging bow CANWiFi can send the charging request to the charging server.

[0034] In some embodiments, the signaling system can determine whether a train car needs to be charged based on the train's operation diagram and the train's battery range. After determining which car needs to be charged, the vehicle controller, train control and management system can send a charging instruction to the battery manager corresponding to the car that needs to be charged. Of course, the charging instruction is also sent to the charging server corresponding to the car at the same time.

[0035] S20, when the battery manager does not receive the charging request reply information sent by the charging server, it continues to receive, wherein the charging request reply information is generated and sent when the charging server receives the charging instruction but does not receive the charging request by continuously re-establishing the communication connection between the first communication device and the second communication device, so as to receive the charging request.

[0036] Specifically, the charging server can repeatedly determine whether it has received the charging request sent by the signal system, and after receiving the charging request, it can generate a charging request reply message, and then send the charging reply message to the battery manager. If the battery manager does not receive the charging request reply message sent by the charging server, it can repeat the reception.

[0037] Among them, when the charging server receives the charging instruction sent by the signal system and does not receive the charging request sent by the battery manager, it can continuously re-establish the communication connection between the vehicle CANWiFi and the charging bow CANWiFi, so that when it receives the charging request sent by the battery manager, it can smoothly send the charging request reply information to the battery manager.

[0038] More specifically, if Figure 3 As shown, when the charger receives the charging instruction sent by the signal system, it can start timing. If it does not receive the charging request sent by the battery manager within 45 seconds, it can be determined that the charging server has timed out from receiving the train charging request. Then the charging server can reconfigure the account and password for the charging bow CANWiFi, and then re-establish the connection between the charging bow CANWiFi and the vehicle CANWiFi to prevent the charging server from being unable to receive the charging request sent by the battery manager due to unsuccessful connection between the charging bow CANWiFi and the vehicle CANWiFi.

[0039] In this embodiment, Figure 3 As shown in the figure, after the battery manager sends a charging request to the charging service, it can enter the judgment stage to determine whether the battery manager has received a response from the charging server to the above charging request. If not, the judgment is repeated. After the charging server receives the charging request sent by the battery manager, it can send a charging request reply to the battery manager via the charging bow CANWiFi to respond that the current charging server has received the charging request of the battery manager. In the process of the battery manager judging whether it has received the charging request reply sent by the charging server, as shown in the figure, Figure 4 As shown, specifically, after the battery manager sends a charging request to the charging server, it enters a timing phase and determines whether a charging request reply sent by the charging bow CANWiFi is received within 120 seconds. If not, the main control chip of the vehicle CANWiFi can control the vehicle CANWiFi to restart, and then re-determine whether a charging request reply sent by the charging bow CANWiFi is received within 120 seconds. If the battery manager receives a charging request reply from the charging server, it means that the battery charger and the charging server have both received the charging request and completed the charging connection. The battery manager can then send a charging reply message to the train control and management system, thereby causing the train charging and management system to stop sending charging requests to the battery charger, so that the battery manager can stop sending charging requests to the charging server.

[0040] In this embodiment, Figure 5As shown, after the train control and management system sends a charging request to the battery manager, it can start timing to determine whether the charging request reply information sent by the battery manager is received within 60 seconds. If the battery manager does not receive the charging request reply information, the train control and management system can control the power of the vehicle CANWiFi to disconnect and restart the vehicle CANWiFi so that the vehicle CANWiFi and the charging bow CANWiFi can be reconnected. After the vehicle CANWiFi is reconnected, the train control and management system can resend the charging request to the battery manager and re-determine whether the charging request reply information sent by the battery manager is received within 60 seconds.

[0041] In some embodiments, as Figure 3 As shown, after the battery manager stops sending charging requests to the charging server, it can determine that the reception and identification timeout has occurred if it does not receive the charger handshake signal and the charger identification signal sent by the charging server within the first preset time, and continue to receive the charger handshake signal and the charger identification signal until it receives the charger handshake signal and the charger identification signal, and then send the vehicle-mounted handshake signal and the vehicle-mounted identification signal to the charging server.

[0042] Specifically, see Figure 3 After the charging server sends a charging request response to the battery manager, it may then send a charger handshake signal and a charger identification signal to the battery manager. Therefore, after the battery manager stops sending charging requests to the charging server, it may determine whether it has received the charger handshake signal and the charger identification signal from the charging server within a first preset time. Optionally, the first preset time may be 70 seconds. If the battery manager does not receive the charger handshake signal and the charger identification signal from the charging server within 70 seconds, it may be determined that the battery manager has timed out from receiving the identification signal. If the battery manager identification timeout occurs, the battery manager may suspend charging and then re-determine whether it has received the charger handshake signal and the charger identification signal from the charging server within 70 seconds until it receives the charger handshake signal and the charger identification signal.

[0043] After the battery manager receives the charger handshake signal and the charger identification signal, it can send the vehicle-mounted handshake signal and the vehicle-mounted identification signal to the charging server via the vehicle CAN / WiFi in response to the charger handshake signal and the charger identification signal sent by the charging server. It should be noted that after sending the charger handshake signal and the charger identification signal to the battery manager, the charging server can time to determine whether the vehicle-mounted handshake signal and the vehicle-mounted identification signal sent by the battery manager are received within a preset time (e.g., 60 seconds). If not, the charging server can determine that the battery manager identification timeout has occurred, and then send a charging termination signal and resend a charging request reply message to the battery manager via the charging bow CAN / WiFi. After receiving the charging request reply message, the battery manager can re-enter the process of determining whether the charger handshake signal and the charger identification signal sent by the charging server are received within the first preset time. It should be noted that after resending the charging request reply message, the charging server can resend the charger handshake signal and the charger identification signal to the battery manager.

[0044] In this embodiment, after the battery manager sends the vehicle-mounted handshake signal and the vehicle-mounted identification signal to the charging server, if it determines that there is a communication failure with the charger, it returns to continue to determine whether the charger handshake signal and the charger identification signal sent by the charging server are received, wherein the battery manager communicates with the charger through the charging server.

[0045] Specifically, after the battery manager receives the charger handshake signal and the charger identification signal within the first preset time, it can send the vehicle handshake signal and the vehicle identification signal to the charging server. If the charging server receives the vehicle handshake signal and the vehicle identification signal within 60 seconds, it can be determined that the battery manager and the charger have completed the communication connection. In this embodiment, after the battery manager and the charger complete the communication connection, Figure 3 As shown, it is possible to further determine whether there is a communication failure between the battery manager and the charger. If the battery manager determines that there is a communication failure between it and the charger, it can return to receive the charger handshake signal and charger identification signal sent to it by the charging server to re-establish the communication connection. If the charging server detects that there is a communication failure between it and the battery manager, it can return to send a charging request reply message to the battery manager to re-establish the communication connection between the charger and the battery manager.

[0046] It should be noted that if Figure 3As shown, after the battery manager and charger confirm that the communication connection is complete, the battery manager can also send the current allowed charging power, SOC, cell voltage, and other data for the battery corresponding to the train car to the charging server. After receiving this data, the charging server can display it so that users can obtain relevant battery information from the charger. Furthermore, the charging server can also send the battery manager data such as the charger's maximum output capacity and the charger's charging status during the charging process. After receiving this data, the battery manager can also display it to facilitate users to obtain relevant charger status data. During the charging process, the battery manager also determines whether the battery's SOC value is equal to 100%. If so, charging is complete and a charging completion signal is sent to the charging server. After receiving the charging completion signal, the charging server can terminate charging, thereby completing the battery charging. It should be noted that if the battery's SOC value is determined to be not equal to 100%, the battery manager resends the battery's current allowed charging power, SOC, cell voltage, and other data to the charging server.

[0047] It is understandable that the charger may compare the maximum allowable charging power of the battery with the maximum output capacity of the charger and charge the battery using the smaller one.

[0048] In summary, the reconnection method for train charging of the embodiment of the present invention can perform unlimited reconnections when an abnormality occurs in the connection process between the train and the charging server to ensure that the train can be charged normally, thereby improving the reliability of train charging.

[0049] Figure 6 2 is a flow chart of a reconnection method for charging a train according to another embodiment of the present invention.

[0050] Furthermore, if Figure 6 As shown, the present invention also proposes another reconnection method for charging a train, wherein the train includes a battery manager and a first communication device connected to the battery manager. The first communication device establishes a communication connection with a second communication device so that the battery manager communicates with the charging server. The reconnection method includes the following steps:

[0051] S100: When receiving a charging instruction, the charging server receives a charging request sent by the battery manager through a second communication device.

[0052] It should be noted that the charging instruction in this embodiment can be issued through the signal system, and, as Figure 2As shown, the train in this embodiment may also include an onboard controller, a train control and management system, etc. When the signal system sends a charging instruction to the battery manager, it may first send the charging instruction to the vehicle controller. In this embodiment, the vehicle controller sends the charging instruction to the train control and management system in a transparent manner, and then the train control and management system sends the charging instruction to the battery manager. When the battery manager receives the charging instruction, it may send a corresponding charging request to the charging server through the first communication device. Specifically, the first communication device may be Figure 2 The car CANWiFi shown in the figure, the second communication device can be the charging bow CANWiFi. When the battery manager receives the charging instruction, it can send a charging request to the charging bow CANWiFi through the car CANWiFi. After receiving the charging request, the charging bow CANWiFi can send the charging request to the charging server.

[0053] In some embodiments, the signaling system can determine whether a train car needs to be charged based on the train's operation diagram and the train's battery range. After determining which car needs to be charged, the vehicle controller, train control and management system can send a charging instruction to the battery manager corresponding to the car that needs to be charged. Of course, the charging instruction is also sent to the charging server corresponding to the car at the same time.

[0054] S200 , when the charging server does not receive a charging request, the charging server continuously re-establishes the communication connection between the second communication device and the first communication device until a charging request is received, and generates charging request reply information.

[0055] Specifically, the charging server can repeatedly determine whether it has received the charging request sent by the signal system, and after receiving the charging request, it can generate a charging request reply message, and then send the charging reply message to the battery manager. If the battery manager does not receive the charging request reply message sent by the charging server, it can repeat the reception.

[0056] Among them, when the charging server receives the charging instruction sent by the signal system and does not receive the charging request sent by the battery manager, it can continuously re-establish the communication connection between the vehicle CANWiFi and the charging bow CANWiFi, so that when it receives the charging request sent by the battery manager, it can smoothly send the charging request reply information to the battery manager.

[0057] In this embodiment, the charging server may reconfigure the second communication device when no charging request is received every third preset time, so as to re-establish the communication connection between the second communication device and the first communication device.

[0058] like Figure 3 As shown, when the charger receives the charging instruction sent by the signal system, it can start timing. If no charging request sent by the battery manager is received within a third preset time, such as 45 seconds, it can be determined that the charging server has timed out from receiving the train charging request. Then the charging server can reconfigure the account and password for the charging bow CANWiFi, and then re-establish the connection between the charging bow CANWiFi and the vehicle CANWiFi to prevent the charging server from being unable to receive the charging request sent by the battery manager due to unsuccessful connection between the charging bow CANWiFi and the vehicle CANWiFi.

[0059] S300: The charging server sends charging request response information to the battery manager.

[0060] Specifically, if Figure 3 As shown, after the battery manager sends a charging request to the charging service, it can enter the judgment phase to determine whether the battery manager has received a response from the charging server to the above charging request. If not, the judgment is repeated. After the charging server receives the charging request sent by the battery manager, it can send a charging request reply to the battery manager via the charging bow CANWiFi to acknowledge that the charging server has received the charging request from the battery manager.

[0061] In the process of determining whether the battery manager has received the charging request reply from the charging server, Figure 4 As shown, specifically, after the battery manager sends a charging request to the charging server, it enters a timing phase and determines whether a charging request reply sent by the charging bow CANWiFi is received within 120 seconds. If not, the main control chip of the vehicle CANWiFi can control the vehicle CANWiFi to restart, and then re-determine whether a charging request reply sent by the charging bow CANWiFi is received within 120 seconds. If the battery manager receives a charging request reply from the charging server, it means that the battery charger and the charging server have both received the charging request and completed the charging connection. The battery manager can then send a charging reply message to the train control and management system, thereby causing the train charging and management system to stop sending charging requests to the battery charger, so that the battery manager can stop sending charging requests to the charging server.

[0062] In this embodiment, Figure 5As shown, after the train control and management system sends a charging request to the battery manager, it can start timing to determine whether the charging request reply information sent by the battery manager is received within 60 seconds. If the battery manager does not receive the charging request reply information, the train control and management system can control the power of the vehicle CANWiFi to disconnect and restart the vehicle CANWiFi so that the vehicle CANWiFi and the charging bow CANWiFi can be reconnected. After the vehicle CANWiFi is reconnected, the train control and management system can resend the charging request to the battery manager and re-determine whether the charging request reply information sent by the battery manager is received within 60 seconds.

[0063] See also Figure 3 After the charging server sends a charging request response to the battery manager, it may then send a charger handshake signal and a charger identification signal to the battery manager. Therefore, after the battery manager stops sending charging requests to the charging server, it may determine whether it has received the charger handshake signal and the charger identification signal from the charging server within a first preset time. Optionally, the first preset time may be 70 seconds. If the battery manager does not receive the charger handshake signal and the charger identification signal from the charging server within 70 seconds, it may be determined that the battery manager has timed out from receiving the identification signal. If the battery manager identification timeout occurs, the battery manager may suspend charging and then re-determine whether it has received the charger handshake signal and the charger identification signal from the charging server within 70 seconds until it receives the charger handshake signal and the charger identification signal.

[0064] After the battery manager receives the charger handshake signal and the charger identification signal, it can send the vehicle-mounted handshake signal and the vehicle-mounted identification signal to the charging server via the vehicle CAN / WiFi in response to the charger handshake signal and the charger identification signal sent by the charging server. It should be noted that after sending the charger handshake signal and the charger identification signal to the battery manager, the charging server can time to determine whether the vehicle-mounted handshake signal and the vehicle-mounted identification signal sent by the battery manager are received within a preset time (e.g., 60 seconds). If not, the charging server can determine that the battery manager identification timeout has occurred, and then send a charging termination signal and resend a charging request reply message to the battery manager via the charging bow CAN / WiFi. After receiving the charging request reply message, the battery manager can re-enter the process of determining whether the charger handshake signal and the charger identification signal sent by the charging server are received within the first preset time. It should be noted that after resending the charging request reply message, the charging server can resend the charger handshake signal and the charger identification signal to the battery manager.

[0065] In some embodiments, after the charging server sends the charging request reply information to the battery manager, the method also includes: sending a charger handshake signal and a charger identification signal to the battery manager through a second communication device, and when the vehicle-mounted handshake signal and the vehicle-mounted identification signal sent by the battery manager are not received within a fourth preset time, determining that the battery manager identification has timed out, and continuing to send the charging request reply information to the battery manager.

[0066] Furthermore, in this embodiment, after receiving the vehicle-mounted handshake signal and the vehicle-mounted identification signal, if the charging server determines that there is a communication failure with the battery manager, it returns to continue sending charging request reply information to the battery manager.

[0067] Specifically, after the battery manager receives the charger handshake signal and the charger identification signal within the first preset time, it can send the vehicle handshake signal and the vehicle identification signal to the charging server. If the charging server receives the vehicle handshake signal and the vehicle identification signal within 60 seconds, it can be determined that the battery manager and the charger have completed the communication connection. In this embodiment, after the battery manager and the charger complete the communication connection, Figure 3 As shown, it is possible to further determine whether there is a communication failure between the battery manager and the charger. If the battery manager determines that there is a communication failure between it and the charger, it can return to receive the charger handshake signal and charger identification signal sent to it by the charging server to re-establish the communication connection. If the charging server detects that there is a communication failure between it and the battery manager, it can return to send a charging request reply message to the battery manager to re-establish the communication connection between the charger and the battery manager.

[0068] It should be noted that if Figure 3As shown, after the battery manager and charger confirm that the communication connection is complete, the battery manager can also send the current allowed charging power, SOC, cell voltage, and other data for the battery corresponding to the train car to the charging server. After receiving this data, the charging server can display it so that users can obtain relevant battery information from the charger. Furthermore, the charging server can also send the battery manager data such as the charger's maximum output capacity and the charger's charging status during the charging process. After receiving this data, the battery manager can also display it to facilitate users to obtain relevant charger status data. During the charging process, the battery manager also determines whether the battery's SOC value is equal to 100%. If so, charging is complete and a charging completion signal is sent to the charging server. After receiving the charging completion signal, the charging server can terminate charging, thereby completing the battery charging. It should be noted that if the battery's SOC value is determined to be not equal to 100%, the battery manager resends the battery's current allowed charging power, SOC, cell voltage, and other data to the charging server.

[0069] It is understandable that the charger may compare the maximum allowable charging power of the battery with the maximum output capacity of the charger and charge the battery using the smaller one.

[0070] In summary, the reconnection method for train charging of the embodiment of the present invention can perform unlimited reconnections when an abnormality occurs in the connection process between the train and the charging server to ensure that the train can be charged normally, thereby improving the reliability of train charging.

[0071] It should be noted that, for other specific implementations of the method for reconnecting a train during charging according to an embodiment of the present invention, reference can be made to the other specific implementations of the method for reconnecting a train during charging in the above embodiment, which will not be described in detail here.

[0072] Furthermore, the present invention also proposes a computer-readable storage medium, which stores a reconnection program for train charging. When the reconnection program is executed by a processor, the reconnection method for train charging in the above embodiment is implemented.

[0073] The computer-readable storage medium in this embodiment stores a reconnection program for train charging. When the reconnection program is executed by the processor, the reconnection method for train charging in the above embodiment can be implemented, so that when an abnormality occurs in the connection process between the train and the charging server, unlimited reconnections can be performed to ensure that the train can be charged normally, thereby improving the reliability of train charging.

[0074] Figure 7 FIG. 4 is a structural block diagram of a battery manager according to an embodiment of the present invention.

[0075] Furthermore, if Figure 7As shown, the present invention proposes a battery manager 10, which includes a memory 11, a processor 12, and a train charging reconnection program stored in the memory 11 and executable on the processor 12.
