[0002] With the continuous progress of new energy technologies, the industrialization of new energy has developed rapidly, expanding various power supply methods for rail vehicles. Technical methods such as third-rail power supply or pantograph-catenary power supply have problems such as high construction and maintenance costs, while another power supply mode without a network based on on-vehicle energy storage has been promoted and developed. New energy rail vehicles are equipped with new energy devices, which have the characteristics of supplying constant energy for a long time and instantaneously outputting and inputting high power, and are a beneficial supplement to traditional rail vehicles.

[0003] During the actual train charging process, charging terminal failures and power battery failures occur from time to time. If not handled in a timely manner, it may cause harm such as a reduction in the performance of the power battery, equipment damage, or even a fire.

[0004] Therefore, how to diagnose possible faults during the charging process on the basis of improving the automation degree of the charging process, achieve the timely elimination of fault states, protect the safety of train power batteries, and improve the reliability and safety of the entire system has become an urgent problem to be solved at present. Summary of the Invention

[0047] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] The solution method for the charging fault of the train power battery provided by the present invention, based on the 5G vehicle-ground communication system (CC), realizes low-latency and high-reliability information transmission between the charging terminal (such as charging equipment like a charger, charging pile, etc.), the power battery and the train network control system TCMS (Train Control Management System, TCMS). Through logical analysis, it judges the train power battery fault and the charging terminal fault, and gives the fault handling process, improving the reliability and safety of the charging scenario of the rail train power battery. The specific implementation is as follows:

[0049] Figure 1 is one of the schematic flowcharts of the method for solving the charging fault of the train power battery provided by the present invention. As Figure 1 shown, the method includes:

[0050] Step 100: When it is determined that the first disconnection request sent by the charging terminal through the vehicle-ground communication system is received, send the first disconnection request and the train power battery fault information to the train power battery;

[0051] Step 200: If the first disconnection success feedback message sent by the train power battery is not received within the first preset time, handle the charging fault of the train power battery according to the fault handling process corresponding to the pantograph lowering command, the charging incomplete information, and the train power battery fault information;

[0052] Among them, the first disconnection request and the train power battery fault information are sent through the vehicle-ground communication system after the charging terminal determines that the train power battery has a fault. The first disconnection request is used to apply for disconnection from the train power battery. After the charging terminal determines that the train power battery has a fault, it executes the fault handling process preset for the train power battery fault information;

[0053] The first disconnection success feedback message is sent after the train power battery receives the first disconnection request, sets the charging current, stops charging, and disconnects from the charging terminal. After the train power battery sets the charging current, stops charging, and disconnects from the charging terminal, it executes the fault handling process preset for the train power battery fault information.

[0054] It should be noted that the execution subject of the above method can be a computer device or a TCMS. Hereinafter, taking the execution subject of the above method as TCMS as an example, the method for solving the charging fault of the train power battery provided by the present invention will be described in detail.

[0055] Optionally, in step 100, referring to Figure 2 , during the charging process, the train power battery LIB has a fault. At this time, the LIB will send its own status information and fault information to the charging terminal (such as a charger, a charging pile).

[0056] In one embodiment, the LIB status information may specifically include the battery capacity, charging current, charging voltage, etc. of the LIB, and the LIB fault information includes different fault conditions and fault causes.

[0057] With the significant development of 5G technology in recent years, a number of new industries have emerged, promoting the development of various new technologies and techniques. Based on the characteristics of large bandwidth and low latency of 5G vehicle-ground communication technology, in the scenario of train charging when entering the station, it can ensure reliable communication between the charging terminal and the train's power battery, and provide a technical basis for the rapid handling of charging faults. Therefore, in one embodiment, the above LIB fault information and LIB status information can be sent to the charging terminal through the TCMS and the vehicle-ground communication system (such as the 5G vehicle-ground communication system).

[0058] The charging terminal periodically receives LIB fault information and LIB status information, and before receiving the LIB application for disconnection from the charging terminal, it periodically and circularly determines whether it can continue charging. If it cannot continue charging, it sends a disconnection request with the LIB (i.e., the first disconnection request) and LIB fault information to the 5G vehicle-ground communication system.

[0059] In one embodiment, if a fault occurs in the LIB, it is determined that charging cannot continue.

[0060] The 5G vehicle-ground communication system sends the first disconnection request and LIB fault information to the TCMS. The TCMS (before receiving this first disconnection request) periodically and circularly determines whether it receives this request. After receiving it, it forwards the first disconnection request and LIB fault information to the LIB.

[0061] In one embodiment, after the charging terminal determines that a fault has occurred in the LIB, it executes a fault handling process preset for the LIB fault information.

[0062] In one embodiment, the fault handling process preset for the LIB fault information can be selected from a preset expert library, and various different fault conditions in the LIB fault information and corresponding fault handling processes are stored in this preset expert library.

[0063] In step 200, before the charging of the LIB is completed, it periodically and circularly determines whether it receives the above first disconnection request. After determining that it has received it, the LIB sets the charging current to 0A, stops charging, disconnects from the charging terminal, and sends a disconnection success message (i.e., the first disconnection success feedback message) to the TCMS.

[0064] In one embodiment, after the train's power battery sets the charging current, stops charging, and disconnects from the charging terminal, it executes a fault handling process preset for the LIB fault information.

[0065] It should be noted that the fault handling processes preset for the same LIB fault information by different execution terminals can be different or the same.

[0066] After the TCMS forwards the above first disconnection request and LIB fault information to the LIB, it starts timing, and determines whether it receives the first disconnection success feedback message sent by the LTB when the timing duration reaches the first preset time (for example, 3s) (if not received within 3s, it directly proceeds to the next step), and then sends the pantograph lowering command, the charging incomplete information, and the LIB fault information to the human-machine interface HMI.

[0067] The TCMS processes the charging faults during the LIB charging process according to the fault handling processes corresponding to the pantograph lowering command, the charging incomplete information, and the LIB fault information.

[0068] The method for solving the charging faults of the train power battery provided by the present invention realizes the control and fault protection of the entire charging process by the real-time mutual transmission of control information and fault information between the train power battery and the charging terminal, executes the preset processing processes for different fault conditions, and improves the reliability and safety level of the system.

[0069] See Figure 3 , further, in an embodiment, the method may specifically further include:

[0070] Step 300: When it is determined that the second disconnection request sent by the train power battery is received, send the second disconnection request and the charging terminal fault information to the charging terminal through the vehicle-ground communication system;

[0071] Step 400: If the second disconnection success feedback message sent by the charging terminal through the vehicle-ground communication system is not received within the first preset time, process the charging faults of the train power battery according to the fault handling processes corresponding to the pantograph lowering command, the charging incomplete information, and the charging terminal fault information;

[0072] Wherein, the second disconnection request and the charging terminal battery fault information are sent after the train power battery determines that the charging terminal has a fault, and the second disconnection request is used to apply for disconnecting the link with the charging terminal;

[0073] The second disconnection success feedback message is sent after the charging terminal disconnects the link with the train power battery when the second disconnection request is received.

[0074] Optionally, in step 300, see Figure 4 , during the charging process, if the charging terminal (such as a charging pile, a charger) has a fault, at this time, the charging terminal will send its own status information and fault information to the LIB.

[0075] In one embodiment, the charging terminal status information may specifically include the working status of each charging module that makes up the charging terminal (such as the fault status or normal status, which is convenient for subsequent maintenance), etc., and the charging terminal fault information includes different fault conditions and fault causes.

[0076] In one embodiment, the above-mentioned charging terminal fault information and charging terminal status information can be sent to the LIB through the TCMS and the vehicle-ground communication system (such as the 5G vehicle-ground communication system). Specifically:

[0077] First, the charging terminal fault information and charging terminal status information are sent to the TCMS through the 5G vehicle-ground communication system.

[0078] Then, the charging terminal fault information and charging terminal status information are sent to the LIB through the TCMS.

[0079] The LIB receives the charging terminal fault information and charging terminal status information, and periodically and cyclically judges whether it can continue charging. If it cannot continue charging, a disconnection request from the charging terminal (i.e., the second disconnection request) and the charging terminal fault information are sent to the TCMS.

[0080] In one embodiment, if a fault occurs in the charging terminal, it is judged that charging cannot continue.

[0081] The TCMS forwards the second disconnection request and the charging terminal fault information to the 5G vehicle-ground communication system.

[0082] After receiving the second disconnection request and the charging terminal fault information, the 5G vehicle-ground communication system forwards them to the charging terminal.

[0083] The charging terminal periodically and cyclically judges whether it has received the above-mentioned second disconnection request. After confirming that it has received the second disconnection request, the charging terminal disconnects the link with the LIB and feeds back a disconnection success message (i.e., the second disconnection success feedback message) to the TCMS.

[0084] In one embodiment, the charging terminal can send the second disconnection success feedback message to the TCMS through the 5G vehicle-ground communication system.

[0085] In step 400, the TCMS starts timing after forwarding the second disconnection request and the charging terminal fault information to the charging terminal, and judges whether it receives the above-mentioned second disconnection success feedback message through the 5G vehicle-ground communication system when the timing duration reaches the first preset time (such as 3 s) (when the charging terminal fails, it is considered that the second disconnection success feedback message cannot be received within 3 s). If it does not receive it, a pantograph lowering command, an information indicating that charging is not completed, and the charging terminal fault information are sent to the human-machine interface HMI, and the process proceeds to the fault handling process.

[0086] The TCMS processes the charging faults during the LIB charging process according to the fault handling procedures corresponding to the current collector dropping command, the incomplete charging information, and the LIB fault information.

[0087] The method for solving the charging faults of the train power battery provided by the present invention is based on 5G communication technology. For the wireless charging scenario of rail trains and charging terminal faults, a complete set of fault handling procedures is proposed, and through the train network control system, various possible fault conditions are processed, thereby improving the operation safety and reliability of the train.

[0088] See Figure 5 , further, in an embodiment, the method may specifically further include:

[0089] Step 1: When it is determined that the third disconnection request sent by the train power battery is received, the third disconnection request and the power battery status information are sent to the charging terminal through the vehicle-ground communication system. The third disconnection request is sent after the train power battery determines that the train power battery charging is completed. The third disconnection request is used to apply for disconnecting the link with the charging terminal, and the power battery status information is used to indicate whether the train power battery is charged.

[0090] Step 2: If the third disconnection success feedback message sent by the charging terminal through the vehicle-ground communication system is received within the first preset time, the third disconnection success feedback message is sent to the train power battery. The third disconnection success feedback message is sent after the charging terminal disconnects the link with the train power battery when the third disconnection request is received.

[0091] Step 3: If the charging completion information sent by the train power battery is received within the second preset time, the current collector dropping command is sent to the current collector, the charging completion information is sent to the human-machine interface, and the train not charging information is sent to the vehicle-ground communication system.

[0092] Optionally, in Step 1, during the charging process, the TCMS sends the LIB status information (used to indicate whether the LIB is charged) to the LIB, and the LIB cyclically judges whether it can continue to charge before charging is completed. When charging is completed (when the battery capacity of the LIB in the LIB status information reaches the preset value, it is considered that charging is completed), the LIB sends the information for applying to disconnect the link with the charger (i.e., the third disconnection request) to the TCMS.

[0093] The TCMS cyclically judges whether the third disconnection request is received. If it is determined that the third disconnection request is received, the third disconnection request is forwarded to the charging terminal through the 5G vehicle-ground communication system.

[0094] In step 2, the charging terminal repeatedly determines whether it has received the above third disconnection request. After receiving it, the charging terminal disconnects from the LIB and feeds back a disconnection success message to the TCMS through the 5G vehicle-ground communication system.

[0095] After the TCMS forwards the 5G vehicle-ground communication system to the charging terminal, it starts timing and determines whether it has received a link disconnection success feedback message, that is, the third disconnection success feedback message, through the 5G vehicle-ground communication system when the timing duration reaches the above first preset time (for example, 3s). That is, when the charging terminal is normal, the third disconnection success feedback message can be received within 3s. After receiving this third disconnection success feedback message, the TCMS forwards this third disconnection success feedback message to the LIB.

[0096] In step 3, the LIB repeatedly determines whether it has received the above third disconnection success feedback message. After receiving it, it sends a charging completion message to the TCMS. After the TCMS forwards the third disconnection success feedback message, it starts timing and determines whether it has received a charging success message when the timing duration reaches the second preset time (for example, 3s) (if not received within 3s, it directly proceeds to the next step). Then, the TCMS sends a pantograph lowering command to the pantograph, sends a charging completion message to the human-machine interface HMI, and sends a train not charging message to the 5G vehicle-ground communication system, and the charging process ends.

[0097] It should be noted that the specific values of the above first preset time and second preset time can be the same or different.

[0098] The method for solving the charging fault of the train power battery provided by the present invention realizes the automatic control of the entire charging process of the rail train. Based on the 5G vehicle-ground communication technology, it realizes the rapid identification of charging faults (charging terminal faults, LIB faults), and gives a fault handling process, preventing the further deterioration of the faults from the root cause, and improving the reliability and safety of the rail train power battery charging scenario.

[0099] See Figure 6 Furthermore, in one embodiment, the method may further specifically include:

[0100] Step 4: When it is determined that the start charging command sent by the train power battery is received, the start charging command is sent to the charging terminal through the vehicle-ground communication system. After the charging terminal receives the start charging command, the charging terminal fault information is sent to the train power battery through the train network control system TCMS and the vehicle-ground communication system;

[0101] Step 5: Receive the feedback message sent by the charging terminal through the vehicle-ground communication system, and send the feedback message to the train power battery. The feedback message is used to indicate that the charging terminal has received the start charging command. After receiving the feedback message, the train power battery sends the train power battery fault information to the charging terminal through the TCMS and the vehicle-ground communication system.

[0102] Optionally, in Step 4, after the charging link between the charging terminal and the LIB is successfully established, the LIB sends a start charging command to the TCMS.

[0103] The TCMS repeatedly determines whether it has received the start charging command, and sends the start charging command to the charging terminal through the 5G vehicle-ground communication system.

[0104] The charging terminal repeatedly determines whether it has received the above start charging command. After receiving the start charging command, the charging terminal sends a feedback message indicating the receipt of the start charging command (i.e., the feedback message) to the TCMS through the 5G vehicle-ground communication system. At the same time, the charging terminal fault information and the charging terminal status information are sent to the LIB through the TCMS and the 5G vehicle-ground communication system.

[0105] In Step 5, the TCMS repeatedly determines whether it has received the above feedback message. After confirming the receipt of the above feedback message, it forwards the feedback message to the LIB.

[0106] In the above process, after receiving the feedback message, the LIB periodically sends the LIB status information and the LIB fault information to the charging terminal through the TCMS and the 5G vehicle-ground communication system.

[0107] The method for solving the charging fault of the train power battery provided by the present invention lays a foundation for the subsequent automatic control of the entire charging process of the rail train based on the fault handling process by quickly identifying charging faults (charging terminal faults, power battery faults).

[0108] See Figure 7 , further, in one embodiment, before Step 4, the method may further specifically include:

[0109] Step a: When it is determined that a link establishment request sent by the train power battery is received, send the link establishment request to the charging terminal through the vehicle-ground communication system. The link establishment request is used to apply for establishing a link with the charging terminal;

[0110] Step b: Receive the link establishment success message sent by the charging terminal through the vehicle-ground communication system. The link establishment success message is sent after the charging terminal successfully verifies the link establishment request;

[0111] Step c: Send the link establishment success message to the train power battery.

[0112] Continue to seeFigure 7 , further, in one embodiment, after step a, the method may further specifically include:

[0113] Step a1: Receive the link establishment failure message and the reason for link establishment failure sent by the charging terminal through the vehicle-ground communication system. The link establishment failure message is sent after the charging terminal fails to verify the link establishment request;

[0114] Step a2: Send the link establishment failure message and the reason for link establishment failure to the train power battery. After receiving the link establishment failure information and the reason for link establishment failure, the train power battery stops sending the link establishment request.

[0115] Optionally, in step a, after LIB determines that charging is ready, it sends a command to apply to establish a link with the charging pile (i.e., a link establishment request) to TCMS. TCMS repeatedly determines whether it has received the link establishment request, and forwards the link establishment request to the charging terminal through the 5G vehicle-ground communication system.

[0116] The charging terminal repeatedly determines whether it has received the link establishment request and verifies the link establishment request. The verification results are as follows: Verification fails. The charging terminal feedbacks the link establishment failure information (i.e., the link establishment failure message) and the reason for link establishment failure to TCMS through the 5G vehicle-ground communication system. TCMS sends a command to lower the current collector to the current collector, and sends the link establishment failure message and the reason for link establishment failure to the human-machine interface HMI; after LIB determines that the link establishment fails, it stops sending the above link establishment request and sends an error message to TCMS, waiting for manual processing; Verification passes. The charging terminal feedbacks the link establishment success message (i.e., the link establishment success message) to TCMS through the 5G vehicle-ground communication system. TCMS feedbacks the link establishment success message to LTB. After LIB determines that the link establishment is successful, it sends a start charging command to TCMS and enters the start charging link.

[0117] The method for solving the charging fault of the train power battery provided by the present invention, based on the vehicle-ground wireless communication technology, can realize the stable communication between the rail train and the ground charging terminal. When a fault occurs in the train power battery or the charging terminal, through the wireless communication network, the real-time mutual transmission of control information and fault information between TCMS, the power battery, and the charging terminal is realized. For different fault conditions, a pre-set processing flow is executed, thereby realizing the control and fault protection of the entire charging process, and improving the reliability and safety level of the system.

The first disconnection success feedback message is sent after the train power battery receives the first disconnection request, sets the charging current, stops charging, and disconnects the link with the charging terminal. After the train power battery sets the charging current, stops charging, and disconnects the link with the charging terminal, it executes a pre-set fault processing procedure for the train power battery fault information.
