DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or server that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0027] With the rapid development of electric vehicles, driving modes have become more and more diversified. The driving modes of electric vehicles include: pure engine drive, pure electric drive, engine and motor hybrid drive, etc. Pure engine drive has high fuel consumption. As the global climate temperature rises, the carbon emissions of the engine are required to be higher. As the oil price increases, the operating cost of the pure engine mode is further increased; the pure electric mode is less used in large-tonnage mine cars. In order to meet the needs of the whole vehicle, more power batteries need to be arranged on the whole vehicle, which is too difficult to arrange and the cost increases. The hybrid drive of the engine and the motor has become the trend of large-tonnage mine car operation. How to improve fuel saving rate and reduce operating costs has become the research direction of various car companies.

[0028] Among them, the trams applicable to the present solution can be divided into urban public transportation trams, intercity and long-distance transportation trams, special-purpose trams (such as electric mining cars), etc. According to the fields or uses, the trams applicable to the present solution can include urban public transportation trams, intercity and long-distance transportation trams, special-purpose trams (such as electric mining cars), etc. In the following embodiment steps of the present application, the electric mining car is taken as an example to illustrate the technical solution of the present application, but it does not constitute a specific limitation.

[0029] In order to solve the above technical problems, the invention of the present invention is that according to the power demand of the whole vehicle, the whole vehicle controller calculates the engine output power, compares the power demand of the whole vehicle, and autonomously adjusts the start and stop of multiple engine circuits. When the power demand of the whole vehicle is less than the full power output of one engine, the second engine can be turned off and only one engine can be used to work, or when the high power output efficiency of one engine is lower than the efficiency of two engines working at low power at the same time (that is, the fuel consumed by one engine is more than the fuel consumed by two engines working at the same time, and the fuel consumption value can be calculated by the whole vehicle controller according to the liquid level sensor value of the fuel tank), the work of two engines can be started. For example, the whole vehicle requires 1000kw power, and the single engine outputs 1000kw (the product of the current sensor value and the voltage sensor value) and the fuel consumption is 100L / h, but the two engines each output 500kw, and the single engine outputs 40L / h. By setting multiple engine circuits, the engine start and stop can be automatically controlled according to the power demand of the whole vehicle and the fuel consumption calculation, effectively reducing the fuel consumption of the whole vehicle.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0031] Combine the following Figure 1 A generator set control system according to some embodiments of the present invention is described.

[0032] like Figure 1As shown, the circuit connection structure of the generator set control system disclosed in the present invention includes: a vehicle controller 1 and multiple engine circuits 2, the engine circuit 2 is used to output a preset two-phase DC voltage when starting; the multiple engine circuits 2 are connected in parallel, and the vehicle controller 1 is electrically connected to the multiple engine circuits 2 through control signal lines; the vehicle controller 1 is used to generate a start-stop strategy for the multiple engine circuits 2 according to the required power of the vehicle, and the start-stop strategy is used to control the simultaneous start of at least one engine circuit 2, so that the accumulated value of the engine output power of at least one engine circuit 2 is equal to the required power of the vehicle, and the accumulated value of the fuel consumption value is the lowest.

[0033] In a specific application scenario, by simultaneously setting up multiple engine circuits 2 connected to the vehicle controller 1, it is convenient to select the start-stop switching of the engine circuit 2, and then select the start-stop scheme that can meet the power requirements of the vehicle and has the lowest fuel consumption from the multiple switching results. The number of engine circuits 2 set in the generator set control system can be set according to the actual application scenario. In the following embodiment steps in this application, the generator set control system includes two parallel engine circuits 2 as an example to illustrate the technical solution in this application, but it does not constitute a specific limitation.

[0034] Each engine circuit 2 includes an engine 21, a generator 22, an inverter module 23 and an excitation controller 24; the vehicle controller 1 is electrically connected to the input end of the engine 21 and the input end of the excitation controller 24, and the output end of the engine 21 and the output end of the excitation controller 24 are electrically connected to the input end of the generator 22, respectively. The vehicle controller 1 is used to control the excitation controller 24 to provide excitation current for the generator 22, and control the engine 21 to drive the generator 22 to rotate at a preset engine speed; the generator 22 is used to output a three-phase AC voltage based on the engine speed and the excitation current; the output end of the generator 22 is electrically connected to the input end of the inverter module 23, and the inverter module 23 is used to convert the three-phase AC voltage into a two-phase DC voltage. The inverter module 23 is a three-way bridge inverter circuit, which includes a voltage stabilizing capacitor 231, and the voltage stabilizing capacitor 231 is used to prevent the two-phase DC voltage from suddenly changing.

[0035] In a specific application scenario, the excitation controller 24 includes a voltage-dividing resistor 241, a relay 242 and a voltage-stabilizing diode 243; the input end of the relay 242 serves as the input end of the excitation controller 24 and is electrically connected to the vehicle controller 1, the output end of the relay 242 is electrically connected to the first end of the voltage-dividing resistor 241, and the second end of the voltage-dividing resistor 241 is electrically connected to the winding of the generator 22; the vehicle controller 1 is used to control the closure of the relay 242 to provide an excitation current for the generator 21; the voltage-dividing resistor 241 is used to shunt the excitation circuit voltage inside the excitation controller 24; the voltage-stabilizing diode 243 is used to stabilize the excitation circuit voltage.

[0036] Specifically, the vehicle controller 1 can output a 24V voltage to the excitation controller 24. The excitation controller 24 controls the relay 242 to close, providing an excitation current to the generator winding, so that the generator 21 generates a magnetic field. The engine 21 rotates with the generator 22, cutting the magnetic field generated by the motor to output a three-phase AC voltage. The voltage-dividing resistor 241 of the excitation controller 24 has the function of shunting the excitation circuit voltage, which can prevent the voltage of the generator winding itself from being too high and burning the excitation winding. When the excitation circuit voltage exceeds the allowable voltage of the Zener diode 243, the Zener diode 243 can be broken down, and an alarm is sounded after the breakdown. At this time, the relay 242 in the excitation controller 24 is disconnected to protect the generator 22 from being damaged.

[0037] like Figure 1 As shown, the engine circuit 2 also includes a current sensor 25, a first voltage sensor 26 and a second voltage sensor 27; the current sensor 25 is connected to the output end of the generator 22, and is used to collect the three-phase AC current of the engine circuit; the first voltage sensor 26 is used to collect the three-phase AC voltage of the engine circuit; the second voltage sensor 27 is used to collect the two-phase DC voltage of the engine circuit.

[0038] Correspondingly, the excitation controller 24 also includes an adjustable resistor 244, which is connected in parallel to both ends of the voltage-dividing resistor 241; the vehicle controller 1 is electrically connected to the second voltage sensor 27; the vehicle controller 1 is used to adjust the resistance value of the adjustable resistor 244 in the multiple engine circuits 2 based on the multiple two-phase DC voltages of the multiple engine circuits 2, so that the multiple two-phase DC voltages remain consistent. By making the multiple two-phase DC voltages output by the multiple engine circuits 2 consistent, it is possible to avoid the multiple inverter modules 23 in the multiple engine circuits 2 from generating a circulating loop when connected to the grid, thereby breaking down the entire high-voltage circuit. Figure 1 As shown, diodes 28 are respectively connected to the positive output ends of the plurality of inverter modules 23 . The diodes 28 have the functions of forward conduction and reverse cutoff, and can effectively prevent the inverter modules 23 from generating a circulating loop.

[0039] When adjusting the resistance value of the adjustable resistor 244 in multiple engine circuits 2 so that multiple two-phase DC voltages are consistent, multiple two-phase DC voltages output by the second voltage sensor 27 of multiple engine circuits 2 can be obtained. When the two-phase DC voltage of a certain engine circuit a is higher than the two-phase DC voltage of another engine circuit b, the vehicle controller 1 can adjust the resistance value of the adjustable resistor 244 in the engine circuit a to reduce the output current of the excitation circuit in the engine circuit a and reduce the speed of the engine 21 in the engine circuit a, so that the three-phase AC voltage generated by the generator 22 is reduced, and the two-phase DC voltage inverted by the inverter module 23 is reduced until it is consistent with the two-phase DC voltage of the engine circuit b; when the two-phase DC voltage of a certain engine circuit a is lower than the two-phase DC voltage of another engine circuit b, the vehicle controller 1 can increase the output current of the excitation circuit in the engine circuit a, and increase the speed of the engine 21 in the engine circuit a, so that the three-phase AC voltage generated by the generator 22 is increased, and the two-phase DC voltage inverted by the inverter module 23 is increased until it is consistent with the two-phase DC voltage of the engine circuit b.

[0040] In a specific application scenario, the vehicle controller 1 is used to calculate the two-phase DC current based on the three-phase AC current, and to calculate the engine output power of the corresponding engine circuit based on the two-phase DC current and the two-phase DC voltage. Specifically, the product of the two-phase DC current and the two-phase DC voltage can be determined as the engine output power of the corresponding engine circuit.

[0041] In summary, according to the generator set control system provided by the present invention, the system includes a vehicle controller and multiple engine circuits, the engine circuit is used to output a preset two-phase DC voltage when starting; the multiple engine circuits are connected in parallel, and the vehicle controller is electrically connected to the multiple engine circuits through a control signal line; the vehicle controller is used to generate a start-stop strategy for multiple engine circuits according to the power demand of the vehicle, and the start-stop strategy is used to control the simultaneous start of at least one engine circuit so that the cumulative value of the engine output power of at least one engine circuit is equal to the power demand of the vehicle, and the cumulative value of the fuel consumption value is the lowest. The engine start and stop can be automatically controlled according to the power demand and fuel consumption calculation of the vehicle, effectively reducing the fuel consumption of the vehicle.

[0042] Figure 2 A flow chart of a generator set control method provided by an embodiment of the present invention, the method can be as follows Figure 1 The generator set control system shown in the figure is executed. Figure 2 As shown, the method may include the following steps:

[0043] Step 210: Determine the engine output power and fuel consumption value of each engine circuit in the plurality of engine circuits.

[0044] For the disclosed embodiment, when determining the engine output power of each engine circuit, the two-phase DC current and the two-phase DC voltage of each engine circuit can be obtained, and then the product of the two-phase DC current and the two-phase DC voltage is determined as the engine output power of the corresponding engine circuit. The vehicle controller can also calculate the fuel consumption value of each engine circuit according to the value of the liquid level sensor of the fuel tank.

[0045] The execution subject of the embodiment of the present disclosure may be a vehicle controller in the generator set control system, which can obtain the engine output power and fuel consumption value of each connected engine circuit in the startup state, and then select the start-stop switching of the engine circuit in real time according to the required power of the vehicle, and then select the start-stop solution that can meet the required power of the vehicle and has the lowest fuel consumption from multiple switching results.

[0046] Step 220: Generate a start-stop strategy for multiple engine circuits according to the required power of the whole vehicle. The start-stop strategy is used to control the simultaneous start of at least one engine circuit so that the accumulated value of the engine output power of at least one engine circuit is equal to the required power of the whole vehicle and the accumulated value of the fuel consumption value is the lowest.

[0047] According to the power demand of the whole vehicle, the whole vehicle controller calculates the engine output power, compares the power demand of the whole vehicle, and autonomously adjusts the start and stop of multiple engine circuits. When the power demand of the whole vehicle is less than the full power output of one engine, the second engine can be turned off and only one engine can be used. Or, when the high-power output efficiency of one engine is lower than the low-power output efficiency of two engines at the same time (that is, one engine consumes more fuel than two engines working at the same time, and the fuel consumption value can be calculated by the whole vehicle controller according to the liquid level sensor value of the fuel tank), the two engines can be started. For example, the whole vehicle requires 1000kw of power, and a single engine outputs 1000kw (the product of the current sensor value and the voltage sensor value) and consumes 100L / h of fuel, but the two engines each output 500kw, and a single engine outputs 40L / h.

[0048] For the disclosed embodiment, the engine output power and fuel consumption value of each of the multiple engine circuits can be obtained in real time; then the start-stop strategy of the multiple engine circuits is generated according to the required power of the whole vehicle, and the start-stop strategy is used to control the start of at least one engine circuit so that the accumulated value of the engine output power of at least one engine circuit is equal to the required power of the whole vehicle, and the accumulated value of the fuel consumption value is the lowest. The technical solution in this application can automatically control the start and stop of the engine according to the power demand and fuel consumption calculation of the whole vehicle, effectively reduce the fuel consumption of the whole vehicle, thereby improving the fuel saving rate and reducing the vehicle volume operation cost.

[0049] Based on the above Figure 2A detailed description of the generator set control method is provided, such as Figure 3 As shown, Figure 3 FIG. 1 is a structural block diagram of a generator set control device according to an exemplary embodiment. Figure 3 As shown, the device comprises:

[0050] A determination module 31, which can be used to determine the engine output power and fuel consumption value of each engine circuit in the plurality of engine circuits;

[0051] The control module 32 can be used to generate a start-stop strategy for multiple engine circuits according to the required power of the whole vehicle. The start-stop strategy is used to control the simultaneous start of at least one engine circuit so that the cumulative value of the engine output power of at least one engine circuit is equal to the required power of the whole vehicle and the cumulative value of the fuel consumption value is the lowest.

[0052] Regarding the device in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiment of the method, and will not be elaborated here.

[0053] The embodiment of the present application can obtain the engine output power and fuel consumption value of each of the multiple engine circuits in real time; then generate the start-stop strategy of the multiple engine circuits according to the required power of the whole vehicle, and the start-stop strategy is used to control the start of at least one engine circuit so that the accumulated value of the engine output power of at least one engine circuit is equal to the required power of the whole vehicle, and the accumulated value of the fuel consumption value is the lowest. The technical solution in the present application can automatically control the start and stop of the engine according to the power demand and fuel consumption calculation of the whole vehicle, effectively reduce the fuel consumption of the whole vehicle, thereby improving the fuel saving rate and reducing the vehicle volume operation cost.
