Description

Technical Field

[0001] The present invention relates to the field of the network control system of EMU trains. Specifically, it relates to a method for quickly identifying the formation state of the network control system during the flexible formation of EMU trains. Background Art

[0002] The existing formation mode of EMU trains is the fixed formation mode, in which the positions and directions of each vehicle in the formation are fixed. When disassembling and re-forming, the formation must be carried out in a fixed manner. Another way is to use multiple single vehicles to form units, and then use multiple units to form a formation. The formation is also relatively fixed, and the identification method is also fixed.

[0003] In the operation of EMU trains, users often allocate EMU trains according to seasonal demands and the number of passengers. For example: during holidays when there are many passengers, multiple EMU trains or single EMU trains are added with one or two additional carriages to increase the number of passengers; in areas with short distances and few people, the number of carriages of a single EMU train is reduced to achieve the purpose of load balance and save resources. Therefore, there is a need for flexible formation of EMU trains. Among them, within the approved carrying capacity range, the formation mode that can increase or decrease the number of carriages, change the direction of carriages, and adjust the position of carriages in the train brings great convenience to the operation.

[0004] By searching for flexible formation and EMU train formation, multiple results are obtained. For example, a safety circuit for a vehicle with flexible formation and the vehicle with flexible formation, patent number CN105620516A, includes an electric coupler, a first selection switch group, a second selection switch group, a first normally closed switch and a second normally closed switch connected in series to form a braking branch. The first selection switch group includes a first normally closed contact pair, a second normally closed contact pair and a first normally open contact pair, which improves the non-failure rate of the train and improves the control ability of the train.

[0005] A method for switching the train operation control mode suitable for flexible formation, patent number CN112406959A, discloses that its steps are: first, the n trains are converted from the autonomous operation mode to the flexible formation operation mode; second, the n trains are converted from the flexible formation operation mode to the autonomous operation mode, which improves the operation efficiency and reduces energy consumption.

[0006] A more flexible method for forming an electric multiple unit train, patent number CN104787048A, discloses that a new type of power electronic transformer with both the functions of a transformer and a traction converter is used as a new power supply device on each carriage of the electric multiple unit train except the head and the tail, making the traction drive system of the whole vehicle more efficient, energy-saving and lightweight. Based on this, the pantograph layout and formation method of the basic motor unit are improved to form a more flexible method for forming an electric multiple unit train.

[0007] During the operation of multiple unit trains, it is inevitable to have situations of re - formation. When the existing multiple unit trains are formed, it is necessary to form vehicle units before formation, and the middle vehicles cannot move in the reverse direction individually. There are certain limitations in operation. Therefore, there is a need for a method that can flexibly identify the formation when the vehicles are arbitrarily formed, and can not affect functions such as the control network, power supply and distribution, and door control.

[0008] Regarding the problems in the related technologies, no effective solutions have been proposed yet. Summary of the Invention

[0009] Regarding the problems in the related technologies, the present invention proposes a method for the network control system of multiple unit trains to quickly identify the formation state during flexible formation, so as to overcome the above - mentioned technical problems existing in the existing related technologies.

[0010] For this purpose, the specific technical solutions adopted by the present invention are as follows:

[0011] A method for the network control system of multiple unit trains to quickly identify the formation state during flexible formation, the method includes the following steps:

[0012] Configure the functions of each single vehicle of the multiple unit train by using the single - vehicle electrical control unit;

[0013] Configure the relatively fixed - position equipment for each single vehicle of the multiple unit train, and configure the touch screen or DIP switch for the single - vehicle electrical control unit;

[0014] Set the car number and vehicle type code of the single vehicle based on the touch screen or DIP switch of the single - vehicle electrical control unit;

[0015] Adjust the physical state of the train formation based on the train - level electrical control unit in the conductor's cab;

[0016] Solidify and save the adjusted physical state of the train formation, and implement the train control logic and communication protocol.

[0017] Further, in the configuration of the functions of each single vehicle of the multiple unit train by using the single - vehicle electrical control unit, the single - vehicle functions include the initial setting of the car type, the identification of the car orientation for different vehicle types, and the functional configuration of the single vehicle;

[0018] Among them, the identification of the car orientation for different vehicle types includes setting the fixed methods for identifying the first end, second end, first side, and second side of the car.

[0019] Further, when configuring the relatively fixed - position equipment for each single vehicle of the multiple unit train, refer to the history of railway vehicles and the user's usage habits.

[0020] Further, when configuring the touch screen or DIP switch for the bicycle electrical control unit, the vehicle type code of the carriage is set through the touch screen or DIP switch during the carriage manufacturing and commissioning process.

[0021] Further, the adjustment of the physical state of the train formation based on the train-level electrical control unit in the mechanic's cab further includes the following steps:

[0022] Configure a formation setting graphical interface based on the train-level electrical control unit in the mechanic's cab and display it on the display screen of the train-level electrical control unit;

[0023] Manually adjust the physical state of the carriages based on the graphical interface and according to the actual formation position and direction of each carriage of the multiple unit train.

[0024] Further, the graphical interface includes the carriage identity number, the number of the carriage in the multiple unit train, the position of the fixed equipment, the position of the added or reduced carriages, the power supply line, and the setting key.

[0025] Further, the implementation of the train control logic further includes the following steps:

[0027] Set the power supply line of the odd car numbers to select the first path of the train power supply in even months, and the power supply line of the even car numbers to select the second path of the train power supply in even months.

[0028] Further, when implementing the train control logic, the algorithm of the train control logic is: A + B = C, C / 2 = D... E;

[0029] Among them, E = 1 means selecting the first path of the train power supply for odd numbers, E = 0 means selecting the second path of the train power supply for even numbers, A is the car number, and B is the month number.

[0030] Further, when implementing the train communication protocol, the DIP switch method is used to set the door address of the door, and the data is transmitted according to the data of the corresponding door when transmitting data.

[0031] Further, when implementing the train communication protocol, the algorithm of the train communication protocol is: A + B = C, C / 2 = D... E;

[0032] Among them, A is the car number and B is the month number;

[0033] Set the default direction in the graphical interface, and when in the default direction, the train-level electrical control unit outputs A = 0, and after changing the direction, the train-level electrical control unit outputs A = 1.

[0034] The beneficial effects of the present invention are as follows: The present invention facilitates the flexible use of EMUs by users, improves the utilization rate of carriages, and reduces the waste of empty carriages. The method for the network control system to quickly identify the formation state during the flexible formation of the EMUs of the present invention has low cost and is easy to implement. The relevant information of a single vehicle is configured in the VCU-M, the train-level information is set in the train-level control unit and published to the network terminals of the whole train, and the control functions of each vehicle are realized through the terminals of each vehicle. There is no need to add many additional devices, and there is no need to change the network configuration during each flexible formation. Therefore, there is no need for users to debug and test the network after adding or reducing carriages. It saves material resources and human resources.

[0035] The present invention has comprehensive functions and can realize the adjustment of the functions of single vehicles and trains after various flexible formations. It plays a positive role in the flexible formation and use of railway vehicles and EMU vehicles, saves material resources and human resources, and greatly facilitates the flexible use of EMUs by users. At the same time, through the retrieval of multiple existing related patents, none of them involve the identification method involved in the present invention. Brief Description of the Drawings

[0048] To further illustrate the embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. They are mainly used to illustrate the embodiments and can be combined with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0049] According to an embodiment of the present invention, a method for a network control system of a multiple unit train to quickly identify the formation state during flexible formation is provided. The identification method adopted by the present invention, after the vehicles are formed in any direction and through a unique setting, enables each control system to correctly obtain the current physical formation state information of the vehicles and operate normally according to the set formation method.

[0050] When the multiple unit train is formed, a single vehicle is taken as the main body, and the direction and quantity of the single vehicle can be flexibly adjusted according to needs, so as to achieve the purpose that the quantity, position and direction of the single vehicle can be freely allocated.

[0051] For example Figure 2 As shown, it is necessary to add a carriage to the original multiple unit train with 2 powered cars and 6 trailer cars to achieve the operation purpose.

[0052] After formation, use the man-machine interface to set the formation diagram according to the actual physical position of the formation. After the setting is completed and published to each terminal, the physical position of the formation vehicles can be identified by each terminal.

[0053] Now, the present invention will be further described in combination with the accompanying drawings and specific implementation manners. As Figure 1 shown, according to the method for a network control system of a multiple unit train to quickly identify the formation state during flexible formation according to an embodiment of the present invention, the method includes the following steps:

[0054] S1. Use the single vehicle electric control unit to perform function configuration on the single vehicle of the multiple unit train;

[0055] Among them, as Figure 3-4As shown, in the function configuration of a single unit of the multiple unit train using the vehicle control unit of the bicycle (VCU-M), the functions of a single unit include the initial setting of the vehicle type of the carriage (such as dining car, second-class seat car, first-class sleeping car, etc.), the identification of the carriage orientation for different vehicle types (for example, looking down at the carriage, the parking brake equipment of the second-class seat car is installed at the second corner, so the direction of a single carriage is relatively clear), and the functional configuration of a single unit (for example: power supply and distribution control selection - line 601 corresponds to the first side; line 602 corresponds to the second side). Among them, the identification of the carriage orientation for different vehicle types includes setting the fixed methods for identifying the first end, second end, first side, and second side of the carriage.

[0056] S2. Configure the equipment for relatively fixing the position of a single unit of the multiple unit train, and configure the touch screen or DIP switch for the vehicle control unit of the bicycle; as Figure 5 shown, take the second-class seat car as an example:

[0057] VCU-M: The vehicle control unit of the bicycle for carriage configuration;

[0058] vehicle type 1: Define the second-class seat car as vehicle type 1;

[0059] vehicle 1 defines the carriage number of this carriage as 1;

[0060] fixed equipment: The fixed equipment (parking brake) is at the second corner;

[0061] Etherent: Ethernet.

[0062] Among them, when configuring the equipment for relatively fixing the position of a single unit of the multiple unit train, refer to the history of Chinese railway vehicles and the usage habits of domestic users. Here, refer to "Railway Vehicle Engineering": "The orientation of passenger cars is defined with the direction in which the piston rod of the brake cylinder extends as the first position, and the opposite direction as the second position. A hand brake is installed at the first end of the passenger car." For example, take the hand brake or parking brake operation panel that is configured for each vehicle as the fixed equipment. In the configuration of vehicle type 1, this equipment is at the second corner.

[0063] When configuring the touch screen or DIP switch for the vehicle control unit of the bicycle, set the vehicle type code of this carriage through the touch screen or DIP switch during the carriage manufacturing and debugging process. For example, set this carriage as vehicle type 1, and by default, recognize the position of the fixed equipment of this vehicle at the second corner from the corresponding configuration file.

[0064] S3. Based on the touch screen or DIP switch of the vehicle control unit of the bicycle, set the carriage number and vehicle type code of the single unit, and conduct the basic composition of the network function connection of the whole train;

[0065] S4. Based on the train-level control unit in the mechanic's cab, adjust the physical state of the train formation;

[0066] Among them, the adjustment of the physical state of the train formation by the train-level control unit based on the mechanic's room further includes the following steps:

[0067] The train-level electrical control unit based on the mechanic's room configures a graphical interface for formation settings and displays it on the display screen of the train-level electrical control unit;

[0068] Based on the graphical interface and according to the actual formation position and direction of each carriage of the multiple unit train, manually adjust the physical state of the carriages.

[0069] The graphical interface includes the carriage identity number, the number of the carriage in the multiple unit train, the position of the fixed equipment (parking brake), the position of the added or removed carriage, the power supply line, and the setting key.

[0070] Such as Figure 6 and 7 shown, are the interface diagram and the logic schematic diagram;

[0071] assistant driver: co-driver

[0072] Main driver: driver

[0073] FXD1 0001: Car No. 0001 of model FXD1 (a type of Tc car)

[0074] vehicle type 1: vehicle type 1

[0075] Fixed equipment: fixed equipment

[0076] Power A: Power supply line A

[0077] FXN3 0001A: Car No. 0001A of model FXN3 (a type of Tc car)

[0078] The figure shows an example of a formation method and the adjusted graphical interface.

[0079] For example, the direction of Car No. 1 is opposite to that of Car No. 2, and the positions of the 1st and 2nd corners of Car No. 1 are opposite to those of the 1st and 2nd corners of Car No. 2.

[0080] S5. After setting in the graphical interface, solidify and save the adjusted physical state of the train formation, and implement the train control logic and communication protocol.

[0081] For example:

[0082] VCU-M controls the power supply selection line of a single car to be connected to Power Supply A or B; in Car No. 1, Line 602 corresponds to Line 601 of Car No. 2.

[0083] Among them, the setting for implementing the train control logic further includes the following steps:

[0084] Set the power supply line of odd car numbers to select the second path of the train power supply in odd months, and the power supply line of even car numbers to select the first path of the train power supply in odd months;

[0085] Set the power supply line of odd car numbers to select the first path of the train power supply in even months, and the power supply line of even car numbers to select the second path of the train power supply in even months.

[0086] When setting the train control logic, the algorithm of the train control logic is as follows:

[0087] A + B = C, C / 2 = D with a remainder of E, when E = 1, select the first path of the train power supply for odd numbers, when E = 0, select the second path of the train power supply for even numbers, where A is the car number and B is the month number.

[0088] For example, the method of selecting the train power supply for car No. 3 in May: 3 + 5 = 8; 8 / 2 = 4 with a remainder of 0;

[0089] The result is an even number, so select the train power supply B.

[0090] That is: car No. 3 is an odd car, and in odd months, select the second path of the train power supply.

[0091] Adopting this control method, the lifespan of components and circuits of a single car is utilized, avoiding waste of resources and improving the service life.

[0092] It will not cause incorrect use in power supply selection.

[0093] This control method can identify the positions of the 1-4 corners of the current car relative to the train formation, facilitating the identification of the physical positions of the doors;

[0094] According to the "formation information" released on the display screen of the train-level control unit, and in accordance with the established network protocol, the physical positions of each door can be identified. For example, if a certain door fails, it can be identified on the interface which side of the train and which car the faulty door is in.

[0095] When setting the train communication protocol, the doors use the DIP switch method to set the door addresses. For example, the door address of the door installed at the first corner is C0. And when transmitting data, the data corresponding to the doors is transmitted. As shown in Table 1:

[0096] Table 1

[0097]

[0098]

[0099] According to the communication protocol, whenFigure 7 In the schematic diagram, the position of the door is marked.

[0100] When setting the train communication protocol, the algorithm of the train communication protocol is as follows:

[0101] A + B = C, C / 2 = D remainder E, where A is the car number, B is the month number, and the default direction is set in the graphical interface (for example Figure 8 the direction of Figure 9 is the default direction), and when in the default direction, the train-level control unit outputs A = 0. For example, when

[0102] the direction is changed, the train-level control unit outputs A = 1. Figure 9 A = 1 means odd, and the doors are displayed according to

[0103] A = 0 means even, and the doors are displayed according to Figure 8 display.

[0104] It is displayed in the formation diagram Figure 10 .

[0105] In this way, when the door opening is displayed on the interface, when car No. 01 opens the 3rd and 1st corner doors, car No. 02 opens the 2nd and 4th corner doors on the same side, which is convenient for passengers to get on and off. It can identify the redundant configuration of the network line, etc.

[0106] The network adopts a redundant scheme of double lines and double paths. The network node identifies the formation information and allocates the double-line paths to achieve the purpose of double-line redundancy.

[0107] Its implementation method is similar to the identification of the doors, ensuring that the links on the same side are connected.

[0108] In Figure 11 , the number of carriages is increased. After corresponding settings are made for a single car, adjustments are made according to the formation physical position in the setting interface, and the flexible formation task of the EMU is completed.

[0109] Such as Figure 11 is the formation schematic diagram:

[0110] Cars No. 1, 2, 3, 4, and 6 are of vehicle type 1; car No. 5 is of vehicle type 2; car No. n is of vehicle type 4, etc.

[0111] The installation position of the fixed equipment or identification of vehicle type 1 is at corner 2; the installation position of the fixed equipment or identification of vehicle type 2 is at corner 1; other vehicle types have similar configurations.

[0112] Car No. 1 was reverse-formed during formation; the setting personnel identify the physical direction of the car through the fixed equipment or identification on the car.

[0113] After identification, the physical position of the marshaling vehicle is set according to the method shown in the figure through a fixed setting interface (such as PTU). After the setting is completed, it is published to each terminal of the train network.

[0114] Each network terminal identifies the physical position and direction of the marshaling vehicle in a unified way and adjusts their own control logic, thus realizing the use of flexible marshaling.

[0115] In summary, the present invention facilitates users to flexibly use EMUs, improve the utilization rate of carriages, and reduce the waste of empty carriages. The method for quickly identifying the marshaling status of the network control system during the flexible marshaling of the EMU of the present invention is low-cost and easy to implement. The relevant information of the single vehicle is configured from the VCU-M, and the train-level information is set from the train-level control unit and published to the network terminal of the entire train, and the control function of each vehicle is realized through each vehicle terminal. There is no need to add many additional equipment, and there is no need to change the network configuration every time the flexible marshaling is performed. Therefore, there is no need for users to debug and test the network after adding or reducing carriages. It saves material resources and human resources. The present invention is comprehensive in function and can realize the adjustment of single vehicle and train functions after various flexible marshaling, such as door control, network and power supply and distribution switching (not limited to this type) functions. It has a positive effect on the flexible marshaling of railway vehicles and EMU vehicles, saves material resources and human resources, and greatly facilitates users to flexibly use EMUs. At the same time, by searching multiple existing related patents, none of them involve the identification method involved in the present invention.

[0116] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
