Petition 870220111031, dated 11 / 30 / 2022, pp. 128 / 204 11 / 77

[00027] In the related technique, power supply for rail vehicles generally uses a line-along power supply approach. For example, high-speed railways use conductor cables laid along the lines, and pantographs on the rail vehicles are in contact with the conductor cables to obtain electricity. Subways use conductor rails laid along the lines, and current receivers on the rail vehicles are in contact with the conductor rails to obtain electricity. In this way, conductor rails or conductor cables need to be laid along the line, and the cost is high.

[00028] In the related technique, there is also an approach of using a power battery to supply power to the rail vehicle. Before the race, the rail vehicle is in a vehicle depot, and the rail vehicle is manually loaded, and then participates in the operation after being fully loaded. In this way, automatic loading of rail vehicles cannot be performed, ground loading equipment cannot obtain real-time status information of the rail vehicle, and a charging system and a signaling system are independent of each other in the charging process.

At the same time, the ground loading equipment can obtain real-time status information from railway vehicles, so that the signaling system can monitor the railway vehicle's status information in real time, improving operational safety, and the railway vehicle can also be scheduled in time according to the railway vehicle's status information.

[00029] The technical solutions of this description are further described in detail with reference to the accompanying drawings.

[00030] FIG. 1 is a schematic scene diagram of a railway vehicle loading control method according to an embodiment of the present description. As shown in FIG. 1, the loading system includes a ground loading station 20 and a railway vehicle 10. The loading station 20 includes a pantograph loader 22. In response to the fact that the railway vehicle 10 needs to be loaded, the pantograph loader 22 descends to be in contact with and electrically connected to a current receiver (not shown) on the railway vehicle 10 to load the railway vehicle 10.

[00031] In order to conveniently describe a scene of a railway vehicle loading control method, FIG. 2 is a schematic architectural diagram of a loading system according to an embodiment of the present description. As shown in FIG. 2, the loading system includes a railway vehicle. Petition 870220111031, dated 11 / 30 / 2022, pp. 130 / 204 13 / 77 10, a signal system 30, and a ground charging station 20. The signal system 30 is wirelessly connected to the rail vehicle 10, and the signal system 30 is connected to the charging station 20 via a wired link.

The ground communication module 23 is configured to provide wireless communication connectivity. In response to the fact that the railway vehicle 10 needs to be loaded, the pantograph loader 22 descends to be in contact with and electrically connected to the current receiver 14. The loading station 20 can be arranged on a railway platform, a vehicle depot, a parking lot, or similar.

[00032] Reference is made to FIG. 3. FIG. 3 is a schematic flowchart of a method for controlling the loading of a railway vehicle according to a Petition 870220111031, dated 11 / 30 / 2022, pp. 131 / 204 14 / 77 embodiment of the present description. As shown in FIG. 3, the method is applied to the ground load controller. The signal system 30 in the present description includes, but is not limited to, an Automatic Train Supervision (ATS) system, an Automatic Train Protection (ATP) system, and an Automatic Train Operation (ATO) system. The signal system in this embodiment is the ATS. The method includes the following steps:

[00033] S101: Rail vehicle vehicle information and a loading request transmitted by an ATS are received, the vehicle information including a direction of movement and a rail vehicle identification number.

[00034] Vehicle information includes at least the direction of movement and the vehicle identification number of the rail vehicle. It should be understood that the direction of movement commonly includes an upward and a downward direction, or a forward and a backward direction. The vehicle identification number is used to represent a vehicle code and to group the vehicle. Each vehicle running on the line has a unique vehicle code, and the vehicle grouping indicates that the vehicle is composed of several compartments. For example, 03ZX001 indicates that the vehicle code is ZX001, and the rail vehicle has three compartments.

[00035] Additionally, in response to the fact that the railway vehicle information transmitted by the signal system is not received within a predetermined time period, an identification device of Petition 870220111031, dated 11 / 30 / 2022, pp. 132 / 204 15 / 77 radio frequency 24 scans a radio frequency marker 15 on the rail vehicle to obtain vehicle information from the rail vehicle. In response to the fact that the signal system fails, vehicle information from the rail vehicle can be obtained through the radio frequency marker 15 on the rail vehicle, thereby improving cargo safety and reliability.

[00036] S102: Wireless communication connection is established with a railway vehicle control unit according to the railway vehicle information.

[00037] Specifically, a wireless communication connection request is initiated to the railway vehicle's vehicle control unit according to the railway vehicle's vehicle information, and after the vehicle control unit receives and confirms a wireless communication connection request, a wireless communication connection is established with the vehicle control unit.

[00038] As a possible implementation, the vehicle information includes a direction of movement and a vehicle identification number of the rail vehicle. The loading server finds, according to a configuration table, a wireless network username and password corresponding to the direction of movement and the vehicle identification number of the rail vehicle, and transmits the wireless network username and password to the vehicle control unit. The vehicle control unit Petition 870220111031, dated 11 / 30 / 2022, pp. 133 / 204 16 / 77 The vehicle receives and compares the wireless network username and password with a pre-stored wireless network username and password, and a wireless communication connection is established with the vehicle control unit after the wireless network username and password are confirmed as being consistent with the pre-stored wireless network username and password.

[00039] S103: A pantograph loader arranged corresponding to the direction of movement of the rail vehicle is determined according to the rail vehicle information.

[00040] The ground loading controller is configured to control the lifting / lowering of all pantograph loaders. Each pantograph loader has an identification code. Since the direction of movement of the rail vehicle is upwards, all pantograph loaders corresponding to the upward direction are identified through these identification codes. Since the direction of movement of the rail vehicle is downwards, all pantograph loaders corresponding to the downward direction are identified through these identification codes. A pantograph loader can correspond to either the upward or downward direction.

[00041] S104: The pantograph loader corresponding to the rail vehicle is controlled to descend. Petition 870220111031, dated 11 / 30 / 2022, pp. 134 / 204 17 / 77

[00042] As a possible implementation, vehicle information includes a direction of movement and a vehicle identification number of the rail vehicle. The determination, according to the rail vehicle's vehicle information, of a pantograph loader corresponding to the rail vehicle specifically includes: To determine, according to the vehicle identification number of the railway vehicle, a pantograph loader corresponding to each compartment of the railway vehicle. The vehicle identification number includes grouping information of the railway vehicle. Taking a 3-group train as an example, the 3-group railway vehicle includes three compartments, and the pantograph loader corresponding to the railway vehicle is determined, that is, the pantograph loader corresponding to the three compartments is determined.

[00043] A pantograph loader arranged in accordance with the direction of movement of the railway vehicle is determined according to the direction of movement of the railway vehicle. Specifically, in response to the fact that the direction of movement of the railway vehicle is upwards, a pantograph loader arranged in accordance with the upward direction of the railway vehicle is determined. In response to the fact that the direction of movement of the railway vehicle is downwards, a pantograph loader arranged in accordance with the downward direction of the railway vehicle is determined. Petition 870220111031, dated 11 / 30 / 2022, pp. 135 / 204 18 / 77

[00044] The pantograph loader corresponding to the railway vehicle is finally determined. The pantograph loader corresponding to the railway vehicle is a pantograph loader that corresponds to each compartment of the railway vehicle and is arranged in accordance with the direction of movement. In this implementation, in response to the determination of the pantograph loader corresponding to the railway vehicle, it needs to be determined according to the vehicle information of the railway vehicle, that is, it needs to be determined according to the direction of movement and the vehicle identification number of the railway vehicle, which ensures the accuracy of the loading and safety.

[00045] As a possible implementation, vehicle information includes a direction of movement and a vehicle identification number of the rail vehicle, and residual capacity information for each compartment. The determination, according to the rail vehicle's vehicle information, of a pantograph loader corresponding to the rail vehicle specifically includes: To determine, according to the vehicle identification number of the rail vehicle and the residual capacity information of each compartment, a pantograph loader corresponding to a compartment to be loaded from the rail vehicle. The vehicle identification number includes the rail vehicle's grouping information. Taking a train of 3 groups as an example, the vehicle Petition 870220111031, dated 11 / 30 / 2022, pp. 136 / 204 19 / 77 railcars with 3 groups include three compartments. The residual capacity information for each compartment shows that a second compartment is the one to be loaded, and the pantograph loader corresponding to the railcar is determined, i.e., a pantograph loader corresponding to the second compartment to be loaded is determined.

[00046] A pantograph loader that is arranged in accordance with the direction of movement of the railway vehicle is determined according to the direction of movement of the railway vehicle. Specifically, in response to the fact that the direction of movement of the railway vehicle is upwards, a pantograph loader arranged in accordance with the upward direction of the railway vehicle is determined. In response to the fact that the direction of movement of the railway vehicle is downwards, a pantograph loader arranged in accordance with the downward direction of the railway vehicle is determined.

[00047] The pantograph loader corresponding to the railway vehicle is finally determined. The pantograph loader corresponding to the railway vehicle is a pantograph loader that corresponds to the compartment to be loaded on the railway vehicle and is arranged in accordance with the direction of movement.

[00048] In this implementation, in response to the determination of the pantograph loader corresponding to the rail vehicle, it needs to be determined that Petition 870220111031, dated 11 / 30 / 2022, pp. 137 / 204 20 / 77 according to the railway vehicle information, that is, it needs to be determined according to the direction of movement and the railway vehicle identification number and the residual capacity of each compartment, and only the compartment that needs to be loaded is loaded, carrying out load management and ensuring load accuracy and safety.

[00049] The following steps can also be performed after step S104: Determine if the descending pantograph loader is the correct descending pantograph for the location.

[00050] In this embodiment, descending pantograph in place refers to the fact that the pantograph loader is in full contact with and electrically connected to the current receiver on the rail vehicle. Specifically, a pressure sensor or a distance sensor may be arranged on the pantograph loader, and whether the descending pantograph is in place can be determined by a pressure signal or a distance signal, and whether the descending pantograph is in place can also be determined by detecting an electrical signal. If the descending pantograph is in place, the arrangement of mutually coupled circuits in the vehicle and the pantograph loader respectively is determined, and the magnitude of a voltage at a detection point is measured. The potential safety hazards caused by the descending pantograph not being in place can be avoided by determining whether the descending pantograph is in place. Petition 870220111031, dated 11 / 30 / 2022, pp. 138 / 204 2Λ / ΊΊ is in place, and charging safety and reliability can be improved.

[00051] A descending pantograph signal on site can also determine if the descending pantograph is on site by arranging the pressure sensor or distance sensor on the rail vehicle and detecting the pressure signal or distance signal through the vehicle control unit, and the descending pantograph signal on site is transmitted to the load controller.

[00052] S105: The start of rail vehicle loading is controlled according to the loading request.

[00053] Specifically, it is controlled to start loading each compartment of the rail vehicle, and the residual capacity of each compartment does not need to be considered at this time. It can also be controlled to start loading only one compartment of the rail vehicle to be loaded. The compartment to be loaded is determined according to the residual capacity information of the rail vehicle.

[00054] In this embodiment, the determination of a compartment to be loaded from the railway vehicle specifically includes the following steps: to establish, through the loading controller, a wireless communication connection with a vehicle control unit of the rail vehicle; and to determine, through the vehicle control unit, a compartment to be loaded according to information from Petition 870220111031, dated 11 / 30 / 2022, pp. 139 / 204 2.2. / ΊΊ residual capacity of each compartment, and transmit the residual capacity information of the compartment to be loaded to the loading controller.

[00055] As a possible implementation, in order to guarantee the consistency of loading of each compartment, that is, in order to guarantee that all compartments are fully loaded at the same time, to ensure that all pantograph loaders can ascend at the same time, thus improving the operational efficiency of rail vehicles, the loading server can also determine a target loading current for each compartment according to the residual capacity and a target capacity of each compartment.

[00056] The target charging current for each compartment is determined. As a possible implementation, firstly, the current charging current of a compartment with the lowest residual capacity is obtained, the reference charging time is determined according to the residual capacity and the current charging current of the compartment with the lowest residual capacity, then the target charging current for each compartment is calculated based on the reference charging time, the residual capacity of each compartment and the target capacity, and the charging server controls the charging of each compartment according to the target charging current.

[00057] The target charging current for each compartment is determined. As another implementation Petition 870220111031, dated 11 / 30 / 2022, pp. 140 / 204 23 / 77 possible, firstly, the residual capacity of all compartments is obtained, an average value is calculated, and the current charging current of a compartment with the smallest difference between the residual capacity and the average value is obtained, the reference charging time is determined according to the residual capacity and the current charging current of the compartment, then the target charging current of each compartment is calculated based on the reference charging time, the residual capacity of each compartment and the target capacity, and the charging server controls the charging of each compartment according to the target charging current.

[00058] Additionally, the pantograph loader is controlled to ascend in response to the fact that the loading of the rail vehicle is finished, and pantograph loader status information indicating that the pantograph loader ascends is transmitted to the vehicle control unit and the signaling system.

[00059] According to the railway vehicle loading control method in this embodiment, a communication connection is established with the corresponding railway vehicle according to the loading request and the vehicle information transmitted by the signal system, and the pantograph loader corresponding to the railway vehicle is controlled to descend, to load the railway vehicle. Through the establishment of the communication connection with the railway vehicle, information of Petition 870220111031, dated 11 / 30 / 2022, pp. 141 / 204 24 / 7 Rail Vehicle Status is obtained in real time. The entire loading process is fully automated, has high loading efficiency, and is safe and reliable. The Rail Vehicle Loading Control method in this embodiment combines the loading system with the signaling system to achieve automatic Rail Vehicle loading, so that the Rail Vehicle can also be loaded during the operation process, and loading efficiency and operation efficiency are improved. At the same time, the ground loading equipment can obtain real-time Rail Vehicle status information, so that the signaling system can monitor the Rail Vehicle status information in real time, improving operational safety, and the Rail Vehicle can also be programmed in time according to the Rail Vehicle status information.

[00060] Reference is made to FIG. 4. FIG. 4 is a schematic flowchart of a railway vehicle loading control method according to an embodiment of the present description. As shown in FIG. 4, the method is applied to the vehicle control unit of the railway vehicle.

The vehicle information is used by the loading controller to control a pantograph loader corresponding to the rail vehicle to descend, and to initiate the loading of the rail vehicle.

[00066] After the pantograph loader descends, a pressure sensor and a distance sensor can be arranged on the rail vehicle, and whether the descending pantograph is in place can be determined by a pressure signal or a distance signal, and whether the descending pantograph is in place can also be determined by detecting an electrical signal.

[00067] The method for controlling the loading of a railway vehicle according to this embodiment is combined with the railway vehicle's signaling system. The signaling system determines a reserved loading parking space according to the information from Petition 870220111031, dated 11 / 30 / 2022, pages 144 / 204 27 / 77 residual capacity, location information, and the rail vehicle's movement plan. After moving to the reserved loading parking space, the rail vehicle establishes a communication connection with a corresponding loading controller. After the pantograph loader descends, it begins loading the rail vehicle. Through the establishment of the communication connection with the corresponding loading controller, a communication connection is established with the loading station. The vehicle's status information is transmitted to the loading controller in real time. Furthermore, the entire loading process is fully automated, has high loading efficiency, and is safe and reliable.

[00068] Reference is made to FIG. 5. FIG. 5 is a schematic flowchart of a method for controlling the loading of a railway vehicle according to an embodiment of the present description. As shown in FIG. 5, the embodiment includes the following steps:

[00069] S301: The vehicle control unit transmits location information and residual capacity information of a rail vehicle to an ATS.

[00070] S302. The ATS determines an address for a reserved loading parking space for the rail vehicle based on residual capacity information, location information, and a rail vehicle movement plan, and transmits the address of the reserved loading parking space to the vehicle control unit. Specifically, a Petition 870220111031, dated 11 / 30 / 2022, pp. 145 / 204 28 / 77 The rail vehicle's cruising range can be determined based on residual capacity information and the rail vehicle's location information, i.e., how far the rail vehicle can travel within its residual capacity. The address of the rail vehicle's reserved loading parking space is determined based on the cruising range and the movement plan. The rail vehicle's movement plan is pre-stored in the ATS.

[00071] The movement plan includes arrival time, departure time, stopping time, stopping location, and loading status, etc.

[00072] The address of the reserved charging parking space includes location information of the reserved charging parking space, information of a station to which it belongs, information of a vehicle depot to which it belongs, etc.

[00073] As a possible implementation, the vehicle control unit can also determine the rail vehicle's cruising range based on residual capacity information and rail vehicle location information, report the cruising range to the ATS, and the address of the rail vehicle's reserved loading parking space is determined by the ATS based on the cruising range and movement plan.

[00074] S303. The vehicle control unit receives the address of the reserved charging parking space transmitted by the ATS, and controls the Petition 870220111031, dated 11 / 30 / 2022, pages 146 / 204 29 / 77 rail vehicle to move to the reserved loading parking space.

[00075] After step S303 is executed, the method additionally includes the following steps:

[00076] The ATS transmits on-site movement information to the loading controller after determining that the rail vehicle is moving to the reserved loading parking space.

[00077] The ATS determines that the rail vehicle moves to the reserved loading parking space, specifically including: The vehicle control unit reports the real-time location information of the rail vehicle; the ATS compares this location information with the address of the reserved loading parking space; and if consistent, determines that the rail vehicle is moving to the reserved loading parking space. The reserved loading parking space may be the rail vehicle's parking space, or it may be arranged separately and is not the rail vehicle's parking space.

[00078] S304: The ATS transmits vehicle information from the rail vehicle and a loading request to a ground loading controller. The ground loading controller is arranged corresponding with the rail vehicle's reserved loading parking space. Petition 870220111031, dated 11 / 30 / 2022, pp. 147 / 204 30 / 77

[00079] Vehicle information includes at least the direction of movement and the vehicle identification number of the rail vehicle. It should be understood that the direction of movement commonly includes an upward and a downward direction, or a forward and a backward direction. The vehicle identification number is used to represent a vehicle code and to group the vehicle. Each vehicle running on the line has a unique vehicle code, and the vehicle grouping indicates that the vehicle is composed of multiple compartments. For example, 0103ZX001 indicates that the vehicle code is ZX001, and the rail vehicle has three compartments.

[00080] In this embodiment, each compartment is provided with a radio frequency marker 15, or only one head vehicle or one tail vehicle is provided with a radio frequency marker 15, or each of the head vehicle and the tail vehicle is provided with a radio frequency marker 15, and the adjustment mode is not limited here.

[00081] As a possible implementation, taking a 3-group vehicle as an example, each of the head and tail vehicles is provided with a radio frequency marker. Vehicle information stored in the radio frequency marker on the head vehicle is 0103ZX001. 0103ZX001 indicates that the direction of movement of the rail vehicle is upwards, the rail vehicle code is ZX001, and the rail vehicle is composed of three compartments. The vehicle information stored by the radio frequency marker on the vehicle Petition 870220111031, dated 11 / 30 / 2022, pp. 148 / 204 31 / 77 tail is 1003ZX001. 1003ZX001 indicates that the direction of movement of the rail vehicle is downwards, the rail vehicle code is ZX001, and the rail vehicle is composed of three compartments.

[00082] In this embodiment, steps S302 and S304 are executed in no particular order, and may or may not be executed simultaneously.

[00083] As a possible implementation, after receiving the rail vehicle loading request transmitted by the ATS, the loading controller calculates a loading duration and feeds it back to the signaling system. The signaling system adjusts an operating plan according to the estimated loading duration and the address of the reserved loading parking space.

[00084] The ATS develops an operating plan for the entire line, every day. The operating plan includes a movement plan for all rail vehicles on the line. Specifically, it includes the arrival and departure times of all rail vehicles, the time it takes to enter and leave the station, dwell time, diversion and overtaking, which vehicles are idle and can be operated online, and the time these vehicles need to go online and offline, which vehicles are in the loading state, how long it takes for them to be fully loaded, etc.

[00085] S305: The loading controller receives vehicle information from the rail vehicle and the loading request, and initiates a request to Petition 870220111031, dated 11 / 30 / 2022, pp. 149 / 204 32. / ΊΊ Wireless communication connection to the vehicle control unit according to the railway vehicle's vehicle information.

[00086] S306: After receiving and confirming the request, the vehicle control unit establishes a wireless communication connection with the charging controller.

[00087] Specifically, the load controller initiates a wireless communication connection request to the rail vehicle's vehicle control unit based on the rail vehicle's vehicle information, and after the vehicle control unit receives and confirms a wireless communication connection request, a wireless communication connection is established with the vehicle control unit.

[00088] As a possible implementation, the vehicle information includes a direction of movement and a vehicle identification number of the rail vehicle. The loading controller finds, according to a configuration table, a wireless network username and password corresponding to the direction of movement and the vehicle identification number of the rail vehicle, and transmits the wireless network username and password to the vehicle control unit. The vehicle control unit receives and compares the wireless network username and password with a pre-stored wireless network username and password, and a wireless communication connection is established with the vehicle control unit after the wireless network username and password are entered. Petition 870220111031, dated 11 / 30 / 2022, pages 150 / 204 33 / 77 confirmed as being consistent with the pre-stored wireless network username and password.

[00089] Additionally, in response to the fact that the rail vehicle vehicle information transmitted by the signal system is not received within a predetermined time period, a radio frequency identification device scans a radio frequency marker on the rail vehicle to obtain the rail vehicle vehicle information.

[00090] In this embodiment, the charging controller establishes a wireless communication connection with the vehicle control unit, the vehicle control unit transmits vehicle information to the charging server, and the charging server receives and compares the vehicle information with the vehicle information transmitted by the ATS, and if they are consistent, it is determined that the communication connection is correct, and the following steps can be performed.

[00091] S307: The loading controller controls, according to the vehicle information from the rail vehicle, a pantograph loader corresponding to the rail vehicle to descend.

[00092] As a possible implementation, vehicle information includes a direction of movement and a vehicle identification number of the rail vehicle. The determination, according to the rail vehicle's vehicle information, of a pantograph loader corresponding to the rail vehicle specifically includes: Petition 870220111031, dated 11 / 30 / 2022, pp. 151 / 204 34 / 77 determine, according to the vehicle identification number of the railway vehicle, a pantograph loader corresponding to each compartment of the railway vehicle. The vehicle identification number includes railway vehicle grouping information. Taking a 3-group train as an example, the 3-group railway vehicle includes three compartments, and the pantograph loader corresponding to the railway vehicle is determined, i.e., the pantograph loader corresponding to the three compartments is determined.

[00093] A pantograph loader arranged in accordance with the direction of movement of the railway vehicle is determined according to the direction of movement of the railway vehicle. Specifically, in response to the fact that the direction of movement of the railway vehicle is upwards, a pantograph loader arranged in accordance with the upward direction of the railway vehicle is determined. In response to the fact that the direction of movement of the railway vehicle is downwards, a pantograph loader arranged in accordance with the downward direction of the railway vehicle is determined.

[00094] The pantograph loader corresponding to the rail vehicle is finally determined. The pantograph loader corresponding to the rail vehicle is a pantograph loader that corresponds to each compartment of the rail vehicle and is arranged in accordance with the direction of movement. In this implementation, in response to the determination of Petition 870220111031, dated 11 / 30 / 2022, pages 152 / 204 35 / 77 pantograph loader in correspondence with the railway vehicle, needs to be determined according to the railway vehicle's vehicle information, that is, it needs to be determined according to the direction of movement and the railway vehicle's identification number, which ensures loading accuracy and safety.

[00095] As a possible implementation, vehicle information includes a direction of movement and a vehicle identification number of the rail vehicle, and residual capacity information for each compartment. The determination, according to the rail vehicle's vehicle information, of a pantograph loader corresponding to the rail vehicle specifically includes: To determine, according to the vehicle identification number of the rail vehicle and the residual capacity information of each compartment, a pantograph loader corresponding to a compartment to be loaded from the rail vehicle. The vehicle identification number includes the rail vehicle's grouping information. Taking a 3-group train as an example, the 3-group rail vehicle includes three compartments. The residual capacity information of each compartment shows that a second compartment is the compartment to be loaded, and the pantograph loader corresponding to the rail vehicle is determined, i.e., a pantograph loader corresponding to the second compartment to be loaded is determined. Petition 870220111031, dated 11 / 30 / 2022, pp. 153 / 204 36 / 77

[00096] A pantograph loader arranged in accordance with the direction of movement of the railway vehicle is determined according to the direction of movement of the railway vehicle. Specifically, in response to the fact that the direction of movement of the railway vehicle is upwards, a pantograph loader arranged in accordance with the upward direction of the railway vehicle is determined. In response to the fact that the direction of movement of the railway vehicle is downwards, a pantograph loader arranged in accordance with the downward direction of the railway vehicle is determined.

[00097] The pantograph loader corresponding to the railway vehicle is finally determined. The pantograph loader corresponding to the railway vehicle is a pantograph loader that corresponds to the compartment to be loaded on the railway vehicle and is arranged in accordance with the direction of movement.

[00098] In this implementation, in response to the determination of the pantograph loader corresponding to the railway vehicle, it needs to be determined according to the vehicle information of the railway vehicle, that is, it needs to be determined according to the direction of movement and the vehicle identification number of the railway vehicle and the residual capacity of each compartment, and only the compartment that needs to be loaded is loaded, performing the intellectualization of loading and ensuring loading accuracy and safety. Petition 870220111031, dated 11 / 30 / 2022, pages 154 / 204 37 / 77

[00099] As a possible implementation, the ground loading controller controls a pantograph loader corresponding to the compartment to be loaded from the rail vehicle in the upward direction for descent, or the ground loading controller controls a pantograph loader corresponding to the compartment to be loaded from the rail vehicle in the downward direction for descent. The compartment to be loaded is determined by the vehicle control unit according to the residual capacity information of the rail vehicle. [000100] As a possible implementation, the pantograph loader corresponding to the rail vehicle is controlled to descend. The pantograph loader corresponding to the rail vehicle is a pantograph loader that corresponds to the compartment to be loaded on the rail vehicle and is arranged in accordance with the direction of movement. [000101] As a possible implementation, the compartment to be loaded from the railway vehicle is determined. The compartment to be loaded is determined according to residual capacity information from each compartment of the railway vehicle. [000102] The pantograph loader that corresponds to the compartment to be loaded on the railway vehicle and is arranged in accordance with the direction of movement is controlled to descend. Each compartment of the railway vehicle is the compartment to be loaded on the railway vehicle. In this embodiment, not only the direction of Petition 870220111031, dated 11 / 30 / 2022, pages 155 / 204 38 / 77 movement of the rail vehicle is considered, but also the grouping of the rail vehicle and the residual capacity of each compartment are taken into account; it is only necessary to lower the compartment to be loaded, which reduces costs and saves time. [000103] As a possible implementation, prior to the execution of step S307, the method additionally includes: receiving, by the loading controller, loading information transmitted by the ATS, and controlling the pantograph loader corresponding with the direction of movement of the rail vehicle to descend only after receiving the loading information. [000104] The following step can also be performed after step S307: determine if the descending pantograph loader is the descending pantograph in place. [000105] In this embodiment, descending pantograph in place refers to the fact that the pantograph loader is in full contact with and electrically connected to the current receiver on the rail vehicle. Specifically, a pressure sensor or a distance sensor may be arranged on the pantograph loader, and whether the descending pantograph is in place can be determined by a pressure signal or a distance signal, and whether the descending pantograph is in place can also be determined by detecting an electrical signal. Whether the descending pantograph is in place is determined by arranging mutually coupled circuits on the vehicle and the pantograph loader respectively, and measuring the magnitude of a voltage on Petition 870220111031, dated 11 / 30 / 2022, pp. 156 / 204 39 / 77 a detection point. The potential safety hazards caused by the descending pantograph not being in place can be avoided by determining if the descending pantograph is in place, and loading safety and reliability can be improved.

[000107] S308: The start of rail vehicle loading is controlled according to the loading request. [000108] Specifically, it is controlled to initiate the loading of each compartment of the rail vehicle, and the residual capacity of each compartment does not need to be considered at this time. A compartment to be loaded from the rail vehicle can also be determined. The compartment to be loaded is determined according to the residual capacity information of the rail vehicle, and it is controlled only to initiate the loading of the compartment to be loaded from the rail vehicle. [000109] Additionally, the pantograph loader is controlled to ascend in response to the fact that the loading of the rail vehicle is finished, and pantograph loader status information indicating Petition 870220111031, dated 11 / 30 / 2022, pp. 157 / 204 40 / 77 that the pantograph loader has ascended is transmitted to the vehicle control unit and the signaling system. [000110] The method of controlling the loading of a railway vehicle according to this embodiment is combined with the railway vehicle's signaling system. The signaling system determines the reserved loading parking space of the railway vehicle according to the residual capacity information, location information, and movement plan of the railway vehicle, and transmits the loading request and vehicle information from the railway vehicle. The vehicle control unit and the loading controller establish a communication connection through the vehicle information, i.e., the railway vehicle and the loading station establish a communication connection, and the pantograph loader corresponding to the railway vehicle is controlled to descend, in order to load the railway vehicle.The vehicle control unit and the loading controller establish a communication connection, and real-time information on the status of the rail vehicle is obtained.

[000118] The railway vehicle's vehicle control unit performs the following steps: [000119] S701: The vehicle control unit receives a hold dispatch instruction transmitted by the signal system. The hold dispatch instruction is used Petition 870220111031, dated 11 / 30 / 2022, pp. 160 / 204 43 / 77 to indicate that the rail vehicle is waiting for the departure sequence. [000120] S702: The vehicle control unit begins to detect if there is a fully loaded compartment in each compartment according to the waiting dispatch instruction. [000121] S703: In response to the fact that there is a fully loaded compartment in each compartment, the vehicle control unit controls a charging circuit of the fully loaded compartment to be switched off and transmits a pantograph rise instruction to the load controller, so that the load controller controls a pantograph charger connected to the fully loaded compartment to rise.

The VOBC 112 and the CCU 111 are arranged in the same compartment or in any compartment, and are arranged in the first compartment in this embodiment. In order to ensure the safe operation of the railway vehicle, a backup vehicle control unit is generally arranged to form a redundant support with another vehicle control unit.

One or more BMSs 113 can be arranged, and three BMSs 113 are arranged in this embodiment, namely, the first BMS 1131, the second BMS 1132 and the third BMS 1133, which are distributed in each compartment and are connected respectively with the CCU 111. Each compartment is provided with a current receiver 14, and electrical power is charged by the pantograph charger to the compartment's power battery via the current receiver 14. Each compartment is provided with vehicle communication modules, namely, the first vehicle communication module 121, the second vehicle communication module 122 and the third vehicle communication module 123, which are respectively connected with the first BMS 1131, the According to BMS [000184 1132] A and the third BMS 1133, charging station 20 includes a ground charging controller, a pantograph charger, and a ground communication module. The charging controller includes a charging server - 211, a charger 213, and a pantograph controller 212. The ground communication module, the charger 213, and the pantograph controller 212 are connected respectively to the loading server 211. The pantograph controller 212 is connected to the pantograph loader. The number of pantograph loaders can be multiple. In this example, only three pantograph loaders are used for the illustration, namely, a first pantograph loader 221, a second pantograph loader 222, and a third loader of Petition 870220111031, dated 11 / 30 / 2022, pages 182 / 204 65 / 77 pantograph 223. The three pantograph loaders are connected to the pantograph controller 212, and the loading server 1 controls the lifting / lowering of the pantograph loader via the pantograph controller. [000185] Each pantograph loader is provided with a load communication module, such as a first ground communication module 231, a second ground communication module 232 and a third ground communication module 233, which establish the communication connection with the vehicle communication modules of the corresponding compartment, such as a first vehicle communication module 121, a second vehicle communication module 122 and a third vehicle communication module 123. [000186] A method for controlling rail vehicle loading is introduced below with reference to FIG. 7 and FIG. 8. Specific implementation steps are as follows: [000187] S501: The CCU transmits the residual capacity information of a rail vehicle's energy battery collected by the battery management system (BMS) of each compartment and location information to the ATS via VOBC. [000188] Residual capacity information refers to the residual capacity information of energy batteries in all compartments of the rail vehicle. [000189] S502: The ATS determines an address for a reserved loading parking space of Petition 870220111031, dated 11 / 30 / 2022, pages 183 / 204 66 / 77 rail vehicle according to residual capacity information, location information and a rail vehicle movement plan, and transmits the address of the loading parking space reserved for the CCU via the VOBC. [000190] S503: The CCU receives the address of the reserved loading parking space transmitted by the ATS, and controls the rail vehicle to move to the reserved loading parking space. S504: The ATS transmits vehicle information from the rail vehicle and a loading request to a ground loading server. The vehicle information includes the direction of movement and the vehicle identification number of the rail vehicle. The ground loading server is arranged correspondingly with the reserved loading parking space of the rail vehicle. [000191] Taking three compartments as an example, the ATS transmits the rail vehicle vehicle information and the loading request to the ground loading server. The vehicle information is 0103ZX001, 01 indicates that the head vehicle is ahead in the direction of travel, 03 indicates that the number of groups is 3, and ZX001 indicates the vehicle number. The vehicle information 1003ZX001 indicates that the tail vehicle is ahead in the direction of travel, the 3-group rail vehicle, vehicle ZX001. [000192] S505: The ATS transmits on-site motion information to the loading server after determining that the rail vehicle is moving into space. Petition 870220111031, dated 11 / 30 / 2022, pages 184 / 204 67 / 77 reserved loading parking. S506: The loading server initiates a wireless communication connection request for each BMS via the ground communication module according to the direction of movement and the vehicle identification number after receiving the movement information at the rail vehicle location, and after each BMS receives and confirms the wireless communication connection request via the vehicle communication module, a wireless communication connection is established between the loading server and each BMS. [000193] In this embodiment, in response to the fact that the rail vehicle has multiple groups, the ground communication module and the vehicle communication module can be arranged in a one-to-one correspondence. Taking three compartments as an example, in the three compartments, each compartment is provided with one vehicle communication module. The corresponding ground loading station is also provided with three ground communication modules. [000194] The sequence describes how the loading server and the BMS establish a wireless communication connection, taking a 3-group vehicle as an example below. In this embodiment, vehicle information includes the direction of movement and the vehicle identification number, which can be represented by the following codes. For example, the vehicle information is 0103ZX001, 01 indicates that the head vehicle is ahead in the direction of travel, 03 indicates that the number of groups is 3, i.e., the rail vehicle includes three compartments, and ZX001 indicates the Petition 870220111031, dated 11 / 30 / 2022, pages 185 / 204 68 / 77 vehicle number. 1003ZX001 indicates that the rear vehicle is ahead in the direction of travel, the 3-group rail vehicle, vehicle ZX001. Each compartment number Username Password ZX001-01 Niegbhekg Jhile3g4 ZX001-02 Gnmiebgg Nie54hr6 ZX001-03 Eenigreles 5enil5e3 [000195] In response to the fact that the ATS transmits 0103ZX001, a first ground communication module is connected, according to the username and password in the table above, to a first vehicle communication module corresponding with ZX001-01, a second ground communication module is connected with a second vehicle communication module corresponding with ZX001-02, and a third ground communication module is connected with a third vehicle communication module corresponding with ZX001-03.

Petition 870220111031, dated 11 / 30 / 2022, pages 186 / 204 69 / ΊΊ [000197] Finally, the upload server establishes a wireless communication connection with each BMS. [000198] In this embodiment, the ground communication module and the vehicle communication module can be CAN-to-WIFI modules, or other BUS-to-WIFI modules. [000199] S507: The loading server determines, according to the direction of movement and the vehicle identification number of the rail vehicle, a pantograph loader corresponding to the rail vehicle, and controls the corresponding pantograph loader to descend via the pantograph controller. [000200] As an implementation of this embodiment, the loading server determines, according to the direction of movement of the railway vehicle, pantograph loaders arranged corresponding to the direction of movement, and determines the number of compartments of the railway vehicle according to the vehicle identification number, in order to determine the pantograph loader corresponding to each compartment of the railway vehicle, thus determining the pantograph loader corresponding to the railway vehicle to be a pantograph loader that corresponds to each compartment of the railway vehicle and is arranged in accordance with the direction of movement. The pantograph loader that corresponds to each compartment of the railway vehicle and is arranged in accordance with the Petition 870220111031, dated 11 / 30 / 2022, pages 187 / 204 70 / 77 The direction of movement is controlled by the pantograph controller to descend. [000201] As an implementation of this embodiment, the vehicle information additionally includes residual capacity information for each compartment of the railway vehicle. A pantograph loader corresponding to the compartment to be loaded of the railway vehicle is determined according to the vehicle identification number of the railway vehicle and the residual capacity information for each compartment, and a pantograph loader arranged in accordance with the direction of movement of the railway vehicle is determined according to the direction of movement of the railway vehicle, in order to determine the pantograph loader corresponding to the railway vehicle. The pantograph loader corresponding to the railway vehicle is a pantograph loader that corresponds to the compartment to be loaded of the railway vehicle and is arranged in accordance with the direction of movement. [000202] The pantograph loader that corresponds to the compartment to be loaded on the rail vehicle and is arranged in accordance with the direction of movement is controlled by the pantograph operator to descend. [000203] S508: The loading server determines that the pantograph loader descends to the location, and controls, according to the loading request, the loader to begin loading the rail vehicle. [000204] The upload server can choose to start uploading from all compartments via Petition 870220111031, dated 11 / 30 / 2022, pages 188 / 204 71 / 77 of the charger or just load the compartment to be charged. [000205] The railway vehicle loading control method in this embodiment combines the loading system with the signaling system to achieve automatic loading of the railway vehicle, so that the railway vehicle can also be loaded during the operation process, and the loading efficiency and operation efficiency are improved. At the same time, the ground loading equipment can obtain real-time railway vehicle status information, so that the signaling system can monitor the railway vehicle status information in real time, improving operational safety, and the railway vehicle can also be programmed in time according to the railway vehicle status information. [000206] As a possible implementation, the rail vehicle vehicle information additionally includes the current receiver distribution information. The sequence describes how to determine the pantograph loader corresponding to each rail vehicle compartment with reference to FIG. 9 and FIG. 10. [000207] In response to the fact that the railway vehicle's current receiver is arranged asymmetrically around a railway vehicle centerline in a direction along its length, the pantograph loader corresponding to each railway vehicle compartment in the upward direction is different from the pantograph loader corresponding to Petition 870220111031, dated 11 / 30 / 2022, pp. 189 / 204 72 / 77 each compartment of the railway vehicle in the downward direction. Taking the vehicle from group 4 in FIG. 9 as an example, the railway vehicle includes a head vehicle, a tail vehicle, a compartment 1 and a compartment 2. The current receivers of compartment 1, compartment 2 and the tail vehicle are arranged in the same position, and the arrangement of the current receiver of the head vehicle is different, i.e., the distribution of the current receivers of the railway vehicle is asymmetrical with respect to the centerline of the railway vehicle in the direction of length. In response to the fact that the direction of movement of the railway vehicle is upward, the pantograph loaders corresponding to the compartments are 001, 002, 004 and 006. In response to the fact that the direction of movement of the railway vehicle is downward, the pantograph loaders corresponding to the compartments are 001, 003, 005 and 006. [000208] In response to the fact that the current receiver of the rail vehicle is arranged symmetrically around the centerline of the rail vehicle in the direction of length, the pantograph loader corresponding to each compartment of the rail vehicle in the upward direction is the same as the pantograph loader corresponding to each compartment of the rail vehicle in the downward direction. Taking vehicle group 4 in FIG. 9 as an example, the rail vehicle includes a head vehicle, a tail vehicle, a compartment 1 and a compartment 2. The Petition 870220111031, dated 11 / 30 / 2022, pp. 190 / 204 73 / 77 current receivers from compartment 1, compartment 2, and the tail vehicle are arranged asymmetrically with respect to the railway vehicle's centerline in the lengthwise direction. Because the railway vehicle's direction of movement is upwards, the pantograph loaders corresponding to the compartments are 001, 003, 004, and 006. Because the direction of movement of the railway vehicle is downwards, the pantograph loaders corresponding to the compartments are also 001, 003, 004, and 006. As a result, the number of pantograph loader and current receiver arrangements can be reduced, thereby reducing costs. [000209] Considering that during the operation of the railway vehicle, the direction of movement changes, i.e., the switching scene, the charging polarity may change at this time. In order to facilitate charging, specifically, the current receiver in this embodiment includes a first electrode plate, a second electrode plate, and a third electrode plate arranged sequentially along a first direction. The first electrode plate and the third electrode plate are symmetrical around the second plate, and the polarity of the first plate and the polarity of the third plate are opposite to the polarity of the second plate. The first direction is a width direction or a length direction of the railway vehicle. For example, in response to the fact that the first electrode plate and the third electrode plate Petition 870220111031, dated 11 / 30 / 2022, pp. 191 / 204 74 / 77 are positive electrodes, the second electrode plate is a negative electrode, or in response to the fact that the first and third electrode plates are negative electrodes, the second electrode plate is a positive electrode. [000210] A current collector is arranged on the corresponding pantograph loader. The current collector includes a first electrode plate and a second electrode plate arranged sequentially along the first direction. The polarities of the first electrode plate and the second electrode plate are opposite. The polarity of the first plate of the current collector is the same as that of the second plate of the current receiver. In response to the fact that the pantograph loader descends on the site, the first electrode plate of the current collector intersects with the second electrode plate of the current receiver, and the first electrode plate of the current collector intersects with the first electrode plate of the current receiver (the rail vehicle runs in the upward direction), or the first electrode plate of the current collector intersects with the third electrode plate of the current receiver (the rail vehicle runs in the downward direction). [000211] That is, in response to the fact that the first electrode plate and the second electrode plate of the current collector are arranged along the first direction, the first electrode plate, the second electrode plate, and the third electrode plate of the current receiver are arranged along the second direction. In Petition 870220111031, dated 11 / 30 / 2022, pages 192 / 204 75 / 77 In response to the fact that the first and third electrode plates of the current receiver are positive electrodes, and the second electrode plate is a negative electrode, the first electrode plate of the current collector is a negative electrode. Alternatively, in response to the fact that the first and third electrode plates of the current receiver are negative electrodes, and the second electrode plate is a negative electrode, the first electrode plate of the current collector is a positive electrode. [000212] In response to the fact that there are multiple compartments, the second electrode plates of multiple current receivers have the same polarity and are located on the centerline of the railway vehicle compartment where the second electrode plates are located. Thus, in response to the fact that the railway vehicle is reversed, there is no need to change the location of the pantograph loader or the location of the current receiver, which can improve the loading flexibility and convenience of the railway vehicle.
