Description

Technical Field

[0001] This application relates to the field of power supply technology for high-speed trains, and in particular to intelligent power supply systems, methods, electronic devices and storage media for high-speed trains. Background Technology

[0002] Currently, the power supply methods for existing railway passenger cars and centralized power EMUs are fixed. When switching the power car end or reversing the trailer car assembly, it can cause confusion in the power supply to the trailer car, making it impossible to correctly identify the correspondence between the power supply circuits of the power car and the trailer car, resulting in the problem of uneven power car load.

[0003] Figure 10 This is the normal formation mode for railway passenger cars and centralized power EMUs. Cars 1-8 automatically control the activation and deactivation of KM1 and KM2 based on the parity of their car numbers. Specifically, KM1 is activated when the car number is odd, and KM2 is activated when the car number is even, thus selecting the power supply circuit. In normal formation, when KM1 is activated in cars 1, 3, 5, and 7, the trailer car determines that it draws power from the power car (FXD1) I circuit and supplies power to the trailer load via the power through-line +601. Similarly, when KM2 is activated in cars 2, 4, 6, and 8, the trailer car determines that it draws power from the power car (FXD1) II circuit and supplies power to the trailer load via the power through-line +602. At this time, the power supply circuit of the power car (FXD1) corresponds one-to-one with the power supply circuit of the trailer.

[0004] like Figure 11 As shown, there are problems with the flexible formation of existing railway passenger cars and centralized power EMUs: when the power car changes ends, the trailer car cannot identify the power car's position. During the automatic power supply circuit selection, when KM1 of cars 1, 3, 5, and 7 is activated, the trailer car determines that it is drawing power from power car I circuit, but actually draws power from power car II circuit, supplying power to the trailer load via the power through line +601; similarly, when KM2 of cars 2, 4, 6, and 8 is activated, the trailer car determines that it is drawing power from power car II circuit, but actually draws power from power car I circuit, supplying power to the trailer load via the power through line +602. At this time, the power supply circuit of the power car and the power draw circuit of the trailer car are reversed. When a power module sends a fault signal, the disordered correspondence will cause the trailer car's load reduction to be ineffective.

[0005] like Figure 12 As shown, when some trailers are grouped in reverse, the trailers cannot be identified from the grouping information. When cars 2, 4, 6, and 8 are grouped in reverse, according to the existing power supply logic (KM1 is activated when the car number is odd, and KM2 is activated when it is even), if KM2 is activated, then cars 1 to 8 will actually draw power from the power car's I circuit. When some trailers are grouped in reverse and automatic power supply is applied, trailer power supply becomes chaotic, and the two power car power supply circuits experience uneven loads, or even one circuit is unloaded while the other is overloaded. This results in a waste of power car output capacity and shortens the lifespan of the power car power supply module.

[0006] To address the problem of chaotic power supply correspondence in existing railway passenger cars and centralized power EMUs during power car switching and trailer car reversal, an intelligent power supply method for EMUs has been invented and designed. Summary of the Invention

The single-vehicle power supply controller controls the opening and closing of KM1 and KM2 in the single-vehicle power supply control circuit to supply power to the train power supply A circuit or the train power supply B circuit according to the train formation information.

[0017] In the above-mentioned intelligent power supply system for high-speed trains, when X = Y + N is an odd number, the single-car power supply controller controls the KM1 to close. If Y = 0, then the train is supplied with power supply A; if Y = 1, then the train is supplied with power supply B.

[0018] When N is an even number, the single-vehicle power supply controller controls KM2 to close. If Y = 0, then power is supplied to the column via line B. If Y = 1, then power is supplied to the column via line A.

[0020] In the aforementioned intelligent power supply system for high-speed trains, Y = P∪QP∩Q, where the power car switching event is P and the trailer car switching event is Q.

[0021] In the aforementioned intelligent power supply system for high-speed trains, when the power car is switching ends and the trailer is being assembled, Y = 1;

[0022] When the power vehicle changes end and the trailer is reversed, Y = 0;

[0023] When the power vehicle does not change end and the trailer is being programmed, Y = 0;

[0058] The embodiments of this application will be described below using intelligent power supply for high-speed trains as an example.

[0059] Example 1

[0060] This embodiment provides an intelligent power supply system for high-speed trains. Please refer to... Figures 1-4 , Figure 1 This is a system hardware composition framework diagram according to an embodiment of this application; Figure 2 This is a schematic diagram of the intelligent power supply system for high-speed trains according to the present invention; Figure 3 This is a diagram showing the power supply control circuit of a single vehicle according to an embodiment of this application; Figure 4 This is a diagram showing the human-machine interface of the centralized control screen according to an embodiment of this application. As shown in the figure, the intelligent power supply system for high-speed trains includes the following steps:

[0061] The train formation information setting unit 41 sets the train formation information and sends the formation information to the train electrical unit.

[0062] The single-car power supply control circuit control unit 42 transmits the train formation information to the single-car power supply control circuit control unit via Ethernet. The single-car power supply control circuit control unit supplies power to train power supply A or train power supply B by controlling the single-car power supply control circuit according to the train formation information.

[0063] In this embodiment, the train formation information setting unit includes:

[0064] The centralized control panel allows users to set train formation information through its human-machine interface and then send the information to the train's electrical system unit via RS232 serial port.

[0065] In specific implementation, such as Figures 1 to 3 As shown, the hardware components of the intelligent power supply system for high-speed trains mainly include the A and B power supply modules of the power car, the centralized control panel, the train electrical unit, the single-car network equipment, the single-car power supply controller, and the single-car power supply control circuit; among them, the power car's co-driver's side is defined as the power supply A circuit, and the power car's driver's side is defined as the power supply B circuit.

[0066] The centralized control panel is used to set the trainset formation information and send the formation information to the train electrical unit via RS232 serial port. The train electrical unit sends the single-car formation information to the single-car network device via Ethernet. The single-car network device sends the single-car formation information to the single-car power supply controller via RS232 serial port. The single-car power supply controller controls the single-car power supply circuit, that is, controls KA10 or KA20 to control the activation and deactivation of KM1 and KM2, providing support for realizing intelligent power supply from a hardware perspective.

[0067] in, Figure 4 As shown, to address the power supply logic confusion caused by power vehicle switching and some trailers being reverse-grouped, a human-computer interaction interface was designed, and the power supply control logic was optimized based on the set grouping information, ultimately achieving intelligent power supply.

[0068] The human-machine interface of the centralized control screen allows setting the position of the power vehicle and the grouping information of each trailer, and defaults to forward grouping of all trailers. When flexible grouping is performed, the grouping information needs to be manually set. After setting, the grouping information of a single vehicle is sent to the power supply controller of each vehicle to control the selection of the power supply circuit of the single vehicle.

[0069] In this embodiment, the single-vehicle power supply control circuit control unit includes:

[0070] The train's electrical unit transmits train formation information to the individual train network equipment via Ethernet.

[0071] The single-car power supply controller sends the train formation information to the single-car power supply controller. Based on the train formation information, the single-car power supply controller controls the opening and closing of KM1 and KM2 in the single-car power supply control circuit to supply power to train supply A or train supply B.

[0072] In the embodiment, when X = Y + N is an odd number, the single vehicle power supply controller controls KM1 to close. If Y = 0, then the power supply to line A is supplied; if Y = 1, then the power supply to line B is supplied.

[0073] When N is an even number, the single-vehicle power supply controller controls KM2 to close. If Y = 0, then the power supply to the B line of the train is supplied; if Y = 1, then the power supply to the A line of the train is supplied.

[0074] Where Y is the train formation identifier, N is the carriage number, and X is the power supply control circuit flag.

[0075] In the embodiment, Y = P∪QP∩Q, where the power vehicle end-switching event is P, and the trailer inversion event is denoted as a trailer reversal event.

[0076] When the power car is changing ends and the trailer is being programmed, Y = 1;

[0077] When the power car changes end and the trailer is reversed, Y = 0;

[0078] When the power car is not changing ends and the trailer is being organized, Y = 0;

[0079] When the power car does not change end and the trailer is reversed, Y = 1.

[0080] In practice, after the regrouping, the grouping information needs to be confirmed on the centralized control panel, that is, the position of the power car and the grouping direction of the trailer need to be set. When the power car changes end (event P), the trailer reverses grouping (event Q), the grouping flag is Y, the car number is N, and the power supply control circuit flag is X, then Y = P∪QP∩Q. When the power car changes end and the trailer is in the correct grouping direction, Y = 1; when the power car changes end and the trailer reverses grouping direction, Y = 0; when the power car does not change end and the trailer is in the correct grouping direction, Y = 0; when the power car does not change end and the trailer reverses grouping direction, Y = 1.

[0081] When X = Y + N is odd, KM1 absorbs and supplies power. If Y = 0, it actually supplies power to line A. If Y = 1, it actually supplies power to line B. When N is even, KM2 absorbs and supplies power. If Y = 0, it actually supplies power to line B. If Y = 1, it actually supplies power to line A.

[0082] Example 2

[0083] This embodiment provides a method for intelligent power supply of high-speed trains. Please refer to... Figures 5 to 6 As shown, Figure 5 This is a flowchart of an intelligent power supply method for high-speed trains according to an embodiment of this application; Figure 6 The power supply circuit logic diagram according to an embodiment of this application is shown in the figure. The intelligent power supply method for high-speed trains includes the following steps:

[0084] Train formation information setting step S1: Set the train formation information and send the formation information to the individual train power supply controller;

[0085] Power supply step S2: The single-car power supply controller supplies power to train supply line A or train supply line B by controlling the single-car power supply control circuit according to the train formation information.

[0086] In specific implementation, such as Figure 6 As shown, the logic of the intelligent power supply circuit for the high-speed train is as follows:

[0087] After setting the grouping information, if the power car changes end, the trailer will be grouped in the reverse direction; otherwise, the trailer group will be grouped in the forward direction. When the trailer is grouped in the reverse or forward direction, the grouping flag is 0; otherwise, the grouping flag is 1. When X = Y + N is odd, after KM1 is powered, if the grouping flag is 0, it is powered by train supply line A; if the grouping flag is not 0, it is powered by train supply line B. When X = Y + N is not odd, after KM2 is powered, if the grouping flag is 0, it is powered by train supply line B; if the grouping flag is not 0, it is powered by train supply line A.

[0088] Example 3

[0089] Please refer to Figures 7 to 9 As shown, the following are examples of normal train formation, power car end-changing train formation, and some trailer reverse formation.

[0090] like Figure 7 As shown, during normal train formation, from X = Y + N, we know Y = 0. The power supply circuit depends on the trailer car number. Therefore, odd-numbered cars are powered by KM1 (supply and power from circuit A), while even-numbered cars are powered by KM2 (supply and power from circuit B). At this time, the power supply circuit correspondence is correct and consistent with reality.

[0091] like Figure 8 As shown, after the power car switches ends, from X = Y + N, we know Y = 1. Therefore, trailer KM2 with odd-numbered carriage numbers draws and supplies power, supplying power to circuit A, while trailer KM1 with even-numbered carriage numbers draws and supplies power, supplying power to circuit B. At this point, the power supply circuit correspondence is correct and matches the actual situation.

[0092] like Figure 9As shown, when cars 2, 4, 6, and 8 are grouped in reverse, according to X = Y + N, we know Y = 1. Therefore, cars 2, 4, 6, and 8 have their power supply connected to KM1, which supplies power to circuit B. When cars 1, 3, 5, and 7 are grouped in forward direction, Y = 0. Therefore, cars 1, 3, 5, and 7 have their power supply connected to KM1, which supplies power to circuit A. At this time, the power supply circuit correspondence is correct and consistent with reality.
