The described embodiments should not be regarded as limiting the present application. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0044] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0045] In the following description, the terms "first\second\third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0047] The embodiments of the present application provide a locomotive system, a vehicle, a control method and device for the locomotive system, an electronic device, a storage medium and a computer program product, which can meet various power supply modes of the vehicle.

[0048] First, the locomotive system provided by the embodiment of the present application is described. Figure 1 , Figure 1 It is an optional structural diagram of a locomotive system provided in an embodiment of the present application, and the locomotive system includes: a power module 101, a power source input circuit 102, a traction inverter 103 and a traction motor 104;

[0049] The power module 101 includes a generator 1011, a power battery 1012 and / or a hydrogen fuel cell 1013;

[0050] The power source input circuit 102 includes a rectifier module 1021 and a DC / DC module 1022;

[0051] The rectifier module 1021 is used to connect to the generator 1011, and when receiving the first electric energy input by the generator 1011, convert the first electric energy into the first target electric energy;

[0052] The DC / DC module 1022 is used to connect to the power battery 1012, and when receiving the second electric energy input by the power battery 1012, convert the second electric energy into the second target electric energy;

[0053] The power source input circuit 102 is also used to connect to the hydrogen fuel cell 1013 to receive the third electric energy input by the hydrogen fuel cell 1013;

[0054] The traction inverter 103 is used to convert the first target electric energy, the second target electric energy or the third electric energy into a working voltage and transmit it to the traction motor 104 .

[0055] In actual implementation, the locomotive system can be a power source mode of "diesel generator + power battery", "pure power battery" or "hydrogen fuel cell + power battery", and its power module 101 can include a generator 1011 and a power battery 1012, or only a power battery 1012, or a hydrogen fuel cell 1013 and a power battery 1012. The locomotive system provided in the embodiment of the present application is compatible with these three power source modes. In actual implementation, the power source input circuit 102 can receive electrical energy input by the generator 1011, the power battery 1012 and / or the hydrogen fuel cell 1013.

[0056] In actual implementation, when the power source input circuit 102 receives the first electric energy input by the generator 1011, the rectifier module 1021 converts the first electric energy into the first target electric energy. Specifically, the first electric energy can be three-phase alternating current, and the first target electric energy is a direct current voltage. Exemplarily, the three-phase alternating current AC680V output by the diesel generator is converted into a direct current voltage of DC870V by the rectifier module. When the power source input circuit 102 receives the second electric energy input by the power battery 1012, the DC / DC module 1022 converts the second electric energy into the second target electric energy. Specifically, the second electric energy can be a direct current of DC530V-DC785V, and the second target electric energy is a direct current voltage of DC870V. The direct current of DC530V-DC785V output by the power battery passes through the bidirectional DC / DC module and raises the voltage to DC870V. When the power source input circuit 102 receives the third electric energy input by the hydrogen fuel cell 1013, it does not convert it. Here, the third electric energy may be a direct current voltage of DC870V.

[0057] In actual implementation, after obtaining the first target electric energy, the second target electric energy or the third electric energy, the traction inverter 103 converts the obtained electric energy into a working voltage and transmits it to the traction motor 104 to provide the working voltage for the traction motor 104. Specifically, the traction inverter 103 inverts the DC 870V DC voltage into a three-phase variable (VVVF, Variable Voltage and Variable Frequency) voltage to provide power to the traction motor 104.

[0058] In the embodiment of the present application, the power module may include a generator, a power battery and / or a hydrogen fuel cell, and the power source input circuit can be compatible with a variety of electrical energy inputs, convert and transmit electrical energy, thereby meeting the vehicle's various power supply modes.

[0059] In some embodiments, the rectifier module 1021 is connected to the DC bus, and is also used to transmit the first target electric energy to the DC bus; the DC / DC module 1022 is connected to the DC bus, and is also used to transmit the second target electric energy to the DC bus; the power source input circuit 102 is connected to the DC bus, and is also used to transmit the third electric energy to the DC bus; the traction inverter 103 is connected to the DC bus, and is also used to obtain the first target electric energy, the second target electric energy or the third electric energy from the DC bus.

[0060] In actual implementation, the power source input circuit 102, the rectifier module 1021, the DC / DC module 1022, and the traction inverter 103 are all connected to the DC bus, and the first target electric energy, the second target electric energy, and the third electric energy can be transmitted to the DC bus by the power source input circuit 102. The traction inverter 103 obtains the first target electric energy, the second target electric energy, or the third electric energy from the DC bus.

[0061] In some embodiments, see Figure 2 , Figure 2 It is an optional structural diagram of the locomotive system provided in the embodiment of the present application. The locomotive system also includes: an auxiliary system 202, connected to the DC bus 201 and the auxiliary load 203, for obtaining target electric energy from the DC bus 201, and transmitting the target electric energy to the auxiliary load 203, wherein the target electric energy is the first target electric energy, the second target electric energy or the third electric energy.

[0062] In actual implementation, the auxiliary system 202 is used to provide power to the auxiliary load 203. Here, the auxiliary system 202 is connected to the DC bus 201 and can obtain target power from the DC bus 201. The target power is the first target power, the second target power or the third power. In the actual scenario, the target power is a DC voltage of DC870V. After obtaining the target power, the auxiliary system 202 transmits the target power to the auxiliary load 203 to power the auxiliary load 203.

[0063] For example, see Figure 3A , Figure 3A is an optional structural diagram of a locomotive system provided in an embodiment of the present application. Here, Figure 3A The locomotive system shown is in the "hydrogen fuel cell + power battery" power source mode. The auxiliary load 203 includes at least one of the following: B side charging gun confirmation signal 2, B side charging gun confirmation signal 1, A side charging gun confirmation signal 2, A side charging gun confirmation signal 1, 24V power supply, 110V power supply, battery power supply, battery, B side battery charging, A side battery charging, 220V household electricity, air compressor 2 preheating, air compressor 1 preheating, power pack preheating, enhanced cold protection, power room fan, battery thermal protection 1, air conditioning, cooling fan, air compressor 2, air compressor 1 and traction fan. See Figure 3B and 3C , Figure 3B is an optional structural diagram of a power module and a power source input circuit provided in an embodiment of the present application, Figure 3C is an optional structural diagram of a power module and a power source input circuit provided in an embodiment of the present application. Here, Figure 3B The power module shown includes a generator 1011 and a power battery 1012, and the corresponding locomotive system is a "hydrogen fuel cell + power battery" power source mode. Figure 3C The power module shown includes a power battery 1012, and the corresponding locomotive system is a "pure power battery" power source mode. The locomotive systems corresponding to each power source mode are the same except that the power module 101 and the power source input circuit 102 are different. For details, see Figure 3A , and thus no longer in Figure 3B and 3C Displayed in.

[0064] In some embodiments, the auxiliary system 202 further includes an auxiliary inverter for converting the target electric energy into an auxiliary working current and transmitting the auxiliary working current to the auxiliary load 203. In actual implementation, the auxiliary inverter inverts DC870V into AC380V to supply power to the subsequent auxiliary load.

[0065] In some embodiments, the auxiliary system 202 further includes an LC filter for filtering the auxiliary working current. In actual implementation, the LC filter is used to output three-phase 380VAC / 50Hz sinusoidal alternating current. Figure 3C In the "pure power battery" power source mode, the locomotive system includes two groups of power batteries, each group of power batteries corresponds to a DC / DC module and an LC filter. In actual implementation, there are 4 groups of auxiliary systems, all of which are powered by the DC bus. The DC870V is inverted into AC380V through the auxiliary inverter to supply power to the subsequent auxiliary loads. In the "pure power battery" power source mode, auxiliary 3 and 4 are equipped with LC filters and output three-phase 380VAC / 50Hz sinusoidal AC. In the "diesel generator + power battery" and "hydrogen fuel cell + power battery" power source modes, auxiliary 4 is equipped with an LC filter and outputs three-phase 380VAC / 50Hz sinusoidal AC.

[0066] In the embodiment of the present application, the locomotive systems of three different power source modes all adopt the B0-B0 axle control scheme, and each vehicle is equipped with a traction converter cabinet, which integrates traction, auxiliary and power battery charging and discharging units. In the "diesel generator + power battery" power source mode, "pure power battery" power source mode, and "hydrogen fuel cell + power battery" power source mode, the traction auxiliary system parameters are different. The traction auxiliary system parameters of the three power source modes are shown in Table 1.

[0067] Table 1 Traction assist system parameters for three power source modes

[0068]

[0069] In addition, the configurations of the main functional components of the three locomotive systems with different power source modes are also different. See Table 2 for the configurations of the main functional components of the system.

[0070] Table 2 Configuration of main functional components of the system in three power source modes

[0071]

[0072]

[0073] In actual implementation, for the 1000kW power platform locomotive system with three different power source modes, in the "pure power battery" power source mode, the traction auxiliary system has the largest parameters and the highest configuration, and is compatible with the system parameters in the "diesel generator + power battery" power source mode and the "hydrogen fuel cell + power battery" power source mode, so the system parameters and configuration design are based on the "pure power battery" power source mode. The three 1000kW power platform locomotive systems with different power sources all adopt the B0-B0 axle control solution. Each vehicle is equipped with a traction converter cabinet, and a converter cabinet integrates traction, auxiliary and power battery charging and discharging units. Among them, in the "diesel generator + power battery" power source mode, the "pure power battery" power source mode, and the "hydrogen fuel cell + power battery" power source mode, the only inconsistency in the traction auxiliary system is the power source input circuit, and the DC / DC module, auxiliary system, and charger system circuits can be reused.

[0074] In addition, in terms of cabinet structure, the three different power source 1000kW power platform locomotive systems use a unified cabinet. The cabinet design adopts a standardized and modular structure. Space and vacancies are reserved on the basis of the pure electric solution cabinet. The converter functional area is divided and expanded. The basic functional unit is componentized and modular products are flexibly configured. The reduced configuration realizes the matching of various power source systems. The cooling method of the traction auxiliary converter cabinet is forced air cooling. The whole cabinet is divided into a sealing area and an air-cooled heat dissipation area. The sealing area is designed according to the IP55 protection level, and the air duct is designed according to the IP20 protection level to ensure the sealing of the cabinet sealing area, reduce dust pollution in the cabinet, and improve system reliability. See Table 3 for the platform converter cabinet interface under the three power source modes.

[0075] Table 3 Platform converter cabinet interface under three power source modes

[0076]

[0077]

[0078] See also Figure 4 , Figure 4It is an optional structural diagram of the motor interface of the locomotive system provided in the embodiment of the present application. In terms of the electrical interface, the 1000kW power platform locomotive system under three different power source modes, the external electrical interfaces of the whole vehicle are arranged on both sides of A / B, and all adopt the bottom outlet method, including 76 high-voltage interfaces, all of which are reserved in the form of high-voltage electrical interface reuse, and the high-voltage interfaces not used for oil and hydrogen electricity can be left vacant. All traction and power battery high-voltage electrical interfaces purchase glands, and the auxiliary high-voltage interfaces are connected with terminal blocks, among which: Side A: power source input interface, 1 ground charging interface, 1 on-board battery charging interface, and the interfaces on the A side are all sealed with metal cable sheaths; Side B: auxiliary and 4-axis traction motor output interfaces, 1 ground charging interface, 1 on-board battery charging interface, and 1 under-vehicle battery interface. Unused electrical interfaces under different power sources are sealed with M40 plugs. See Table 4 for the external interfaces of the locomotive system in three power source modes.

[0082] 1) According to different customer needs and different application scenarios, through the top-level system design, identify the functional and configuration differences of the vehicle system under the three power source modes of "power battery + diesel generator set", "pure power battery" and "power battery + hydrogen fuel cell", and realize the unified design of traction auxiliary systems of different power levels;

[0083] 2) Based on the concept of vehicle simplification and standardization, the system is compatible with the three power source modes of oil-electric, pure electric and hydrogen-electric through the configuration of different functional units. The main circuit topology of the system is simplified, the cabinet is designed for compatibility, and the main components are reused to improve reliability.

[0084] 3) The main circuit topology of the system is simplified and unified, the intermediate DC voltage is DC 870V, the auxiliary system load and charger load are unified, and the traction auxiliary control system adopts the main control board component installed on the power module to achieve the control of DC / DC, traction, and auxiliary, and low-cost, high-integration optimization and upgrade; the core components are simplified and unified to enhance product availability and interchangeability, reduce product quality cost losses, and improve the overall reliability of the system;

In practical applications, the electronic device 600 can be implemented as Figure 5 With reference to the control unit 501 in the figure, the electronic device for implementing the control method of the locomotive system of the embodiment of the present application is described below.

[0089] Figure 6 The electronic device 600 shown includes: at least one processor 601 and a memory 602. The various components in the electronic device 600 are coupled together via a bus system 603. It is understood that the bus system 603 is used to achieve connection and communication between these components. In addition to the data bus, the bus system 603 also includes a power bus, a control bus, and a status signal bus. However, for the sake of clarity, the bus system 603 is not described in detail. Figure 6 Various buses are labeled as bus system 603.

[0090] Processor 601 can be an integrated circuit chip with signal processing capabilities, such as a general-purpose processor, a digital signal processor (DSP), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc., where the general-purpose processor can be a microprocessor or any conventional processor, etc.

[0091] The memory 602 may be removable, non-removable, or a combination thereof. Exemplary hardware devices include solid-state memory, hard disk drives, optical disk drives, etc. The memory 602 may optionally include one or more storage devices that are physically remote from the processor 601.

[0092] The memory 602 includes a volatile memory or a non-volatile memory, and may also include both volatile and non-volatile memories. The non-volatile memory may be a read-only memory (ROM), and the volatile memory may be a random access memory (RAM). The memory 602 described in the embodiment of the present application is intended to include any suitable type of memory.

[0093] In some embodiments, the memory 602 can store data to support various operations. Examples of these data include programs, modules, and data structures, or subsets or supersets thereof. In the embodiment of the present application, the memory 602 stores an operating system 6021 and a control device 6022 based on a locomotive system; specifically,

[0094] Operating system 6021, including system programs for processing various basic system services and performing hardware-related tasks, such as a framework layer, a core library layer, a driver layer, etc., for implementing various basic services and processing hardware-based tasks;

[0095] In some embodiments, the control device based on the locomotive system provided in the embodiments of the present application can be implemented in a software manner. Figure 6 The control device 6022 based on the locomotive system stored in the memory 602 is shown, which can be software in the form of programs and plug-ins, including the following software modules: a first control module 60221 and a second control module 60222. These modules are logical, so they can be arbitrarily combined or further split according to the functions implemented. The functions of each module will be described below.

[0096] In other embodiments, the control device based on the locomotive system provided in the embodiments of the present application can be implemented in hardware. As an example, the control device based on the locomotive system provided in the embodiments of the present application can be a processor in the form of a hardware decoding processor, which is programmed to execute the control method based on the locomotive system provided in the embodiments of the present application. For example, the processor in the form of a hardware decoding processor can adopt one or more application specific integrated circuits (ASICs), DSPs, programmable logic devices (PLDs), complex programmable logic devices (CPLDs), field programmable gate arrays (FPGAs) or other electronic components.

[0099] Step 701, in response to the start-up of the generator, controlling the power source input circuit to be disconnected from the power battery and the hydrogen fuel cell;

[0100] Step 702: In response to the absence of the generator in the vehicle or the generator stopping working, controlling the power source input circuit to connect to the power battery or the hydrogen fuel cell.

[0101] In actual implementation, if the generator of the vehicle is started, that is, the generator generates electricity for the vehicle, the control unit controls the power battery and the hydrogen fuel cell to disconnect. It should be noted that if the vehicle has both a power battery and a hydrogen fuel cell, both are controlled to disconnect from the power source input circuit. If the vehicle only has a power battery or a hydrogen fuel cell, the power battery or the hydrogen fuel cell is controlled to disconnect from the power source input circuit. If the vehicle does not have a power battery and a hydrogen fuel cell, no control is required. If the vehicle does not have a generator or the generator stops working, the power source input circuit is controlled to be connected to the power battery or the hydrogen fuel cell, that is to say, the operation of the generator is given priority, and when the generator is working, the battery is prevented from generating electricity to protect the battery.

[0102] The following is a description of an exemplary structure of a locomotive system control device 602 provided in an embodiment of the present application implemented as a software module. In some embodiments, for example, Figure 6 As shown, the software modules stored in the control device 6022 of the locomotive system in the memory 602 may include:

[0103] A first control module 60221 is used for controlling the power source input circuit to be disconnected from the power battery and the hydrogen fuel cell in response to the start-up of the generator;
