[0002] At present, when the engine of multi-fuel generator sets on the market is turned off, some unburned fuel will be sucked into the muffler. Since the inside of the muffler is hot, the fuel will explode in the muffler, making a loud noise, affecting the user experience. If the muffler has a catalyst, it will also cause the catalyst to be damaged, resulting in the failure of the muffler or substandard emissions, which will have an impact on the environment.

[0003] The current usage requirements of generator sets on the market include: after the user has finished using the generator, run it at no load for 1 minute and then shut down the generator. Although this requirement can prevent some unburned fuel from being sucked into the muffler and causing an explosion, most users shut down the generator immediately after using it. Therefore, this requirement does not meet the user's usage habits and still carries a certain risk of explosion.

[0039] 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 creative work are within the scope of protection of this application.

[0040] The core of this application is to provide a multi-fuel generator set control method, device, electronic equipment and medium.

[0041] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] FIG1 is a flow chart of a multi-fuel generator set control method provided in an embodiment of the present application, as shown in the figure, comprising the following steps:

[0043] S10: Acquire a speed signal representing the speed of the generator in real time.

[0044] S11: If the speed signal indicates that the current speed of the generator is non-zero, a fuel switching signal is obtained, and the solenoid valve corresponding to the fuel switching signal is controlled to be energized to connect the fuel transmission channel.

[0045] S12: If the speed signal indicates that the current speed of the generator is zero, the corresponding solenoid valve in the multi-fuel generator set is controlled to be de-energized to disconnect the fuel delivery channel.

[0046] In a specific embodiment, the multi-fuel generator set control method provided in the present application is applied to a multi-fuel generator set, and the structural schematic diagram of the multi-fuel generator set is shown in Figure 2, wherein the multi-fuel generator set includes: a liquefied petroleum gas storage tank 1 (LPG Tank), an LPG first-level pressure reducing valve 2, a natural gas connector 3 (NG connector), an LPG / NG second-level pressure reducing solenoid valve 4, an LPG / NG control solenoid valve 5, a fuel switching switch 6, a fuel tank 7, a carburetor 8, a fuel solenoid valve 9, a generator 10, a start switch 11, a battery 12 (storage battery) and a control module 13, and their specific connection relationship is shown in the figure. The working principle of the multi-fuel generator set corresponding to Figure 2 is as follows: after liquefied petroleum gas (LPG) or natural gas (NG) is output through the LPG primary pressure reducing valve 2, it is then subjected to secondary pressure reduction through the LPG / NG secondary pressure reducing solenoid valve 4. Due to the different delivery volumes of LPG and NG, the metering orifice in the LPG / NG control solenoid valve 5 needs to be switched at any time to meet the different demands for LPG and NG, so as to realize the transmission of LPG or NG. After passing through the LPG / NG control solenoid valve 5, the LPG or NG and GAS (fuel) enter the generator 10 through the carburetor 8. During this process, the battery 12 supplies power to related devices, the start switch 11 realizes the start and stop of the generator 10, and the fuel switching switch 6 and the control module 13 connect the LPG / NG secondary pressure reducing solenoid valve 4, the LPG / NG control solenoid valve 5 and the fuel solenoid valve 9 to realize the on and off of the solenoid valves.

[0047] The circuit diagram corresponding to the structural principle diagram shown in Figure 2 is shown in Figure 3, wherein different gears in the starting switch 11 are respectively connected to the battery 12, the starting motor 14, the oil level sensor 15, the oil alarm 16, the spark plug 17, the ignition coil 18 and the control module 13, and the control module 13 is connected to the charging coil 19 and the fuel switching switch 6, and the fuel switching switch 6 is respectively connected to the coil 41 corresponding to the LPG / NG secondary pressure reducing solenoid valve 4, the coil 51 corresponding to the LPG / NG control solenoid valve 5, and the coil 91 corresponding to the fuel solenoid valve 9.

[0048] In this structure, the control module 13 can obtain the speed signal representing the generator speed in real time by connecting with the generator 10. If the current speed of the generator 10 is zero, it means that the current generator 10 is in a shutdown state. At this time, in order to avoid unburned fuel entering the muffler and causing explosion, it is necessary to immediately switch the fuel transmission channel, that is, control the corresponding solenoid valve in the multi-fuel generator set to be powered off to disconnect the fuel delivery channel. If the speed of the generator 10 is not zero, it means that fuel is currently required to enter the generator. Since the generator 10 can only process one fuel at the same time, the fuel switching signal generated by the fuel switching switch 6 is required. At this time, the LPG first-level pressure reducing valve 2 is energized, and the solenoid valve corresponding to the fuel switching signal is further controlled to be energized (LPG / NG second-level pressure reducing solenoid valve 4, LPG / NG control solenoid valve 5 and fuel solenoid valve 9) to connect the fuel transmission channel.

[0049] Among them, it should be noted that when the generator speed is not zero, controlling the solenoid valve corresponding to the fuel switching signal essentially adjusts the on and off of each solenoid valve in the current multi-fuel generator set to ensure that only one channel can realize the transmission of the fuel corresponding to the fuel switching signal.

[0050] It should also be noted that the present application can also determine the state of the generator 10 through the spark plug 17 and the ignition coil 18 .

[0051] The present application provides a method for controlling a multi-fuel generator set, including: obtaining a speed signal representing the speed of the generator in real time; if the speed signal represents that the current speed of the generator is non-zero, obtaining a fuel switching signal, and controlling the solenoid valve corresponding to the fuel switching signal to be energized to connect the fuel transmission channel; if the speed signal represents that the current speed of the generator is zero, controlling the corresponding solenoid valve in the multi-fuel generator set to be de-energized to disconnect the fuel transmission channel. It can be seen that the present application is applicable to a multi-fuel generator set, in which the valve at the pipeline for transporting fuel in the generator set is a solenoid valve, so when the generator speed is detected to be zero, the corresponding solenoid valve is controlled to be de-energized, so as to achieve the purpose of instantly cutting off the fuel transmission channel, and at the same time, the real-time detection of the motor speed can further ensure the speed of cutting off the fuel transmission channel, thereby preventing the unburned fuel from being sucked into the muffler and causing deflagration.

[0052] On the basis of the above embodiment, as shown in FIG2 , controlling the solenoid valve corresponding to the fuel switching signal to be energized includes:

[0053] When the fuel switching signal indicates that the current channel transmits liquefied petroleum gas, and the first-level pressure reducing valve (LPG first-level pressure reducing valve 2) is always in the energized state, the second-level pressure reducing solenoid valve 4 and the control solenoid valve 5 are controlled to be energized, and the fuel solenoid valve 9 is de-energized; to ensure that the current fuel transmission channel is: liquefied petroleum gas (LPG)-first-level pressure reducing valve (LPG first-level pressure reducing valve 2)-second-level pressure reducing solenoid valve (LPG / NG second-level pressure reducing solenoid valve 4)-control solenoid valve (LPG / NG control solenoid valve 5)-carburetor 8-generator 10, wherein the channel connecting the control solenoid valve 5 and the second-level pressure reducing solenoid valve 4 is switched to the liquefied petroleum gas channel (it can also be understood as: the metering hole corresponding to the control solenoid valve 5 is the liquefied petroleum gas metering hole corresponding to the liquefied petroleum gas) to meet the current demand for the liquefied petroleum gas transmission volume, and the metering hole cannot pass natural gas (NG), and at the same time, the fuel solenoid valve 9 is controlled to be de-energized to prevent fuel (GAS) from entering the generator 10 at the same time.

[0054] When the fuel switching signal indicates that the current channel transmits natural gas, the secondary pressure reducing solenoid valve 4 and the control solenoid valve 5 are energized, and the fuel solenoid valve 9 is de-energized; to ensure that the current fuel transmission channel is: natural gas (NG)-secondary pressure reducing solenoid valve (LPG / NG secondary pressure reducing solenoid valve 4)-control solenoid valve (LPG / NG control solenoid valve 5)-carburetor 8-generator 10, wherein the channel connecting the control solenoid valve 5 and the secondary pressure reducing solenoid valve 4 is switched to the natural gas channel (it can also be understood as: the metering hole corresponding to the control solenoid valve 5 is switched to the natural gas metering hole) to meet the current demand for natural gas transmission volume, and at this time the primary pressure reducing valve (LPG primary pressure reducing valve 2) is not energized, that is, liquefied petroleum gas cannot pass through this channel, and at the same time the fuel solenoid valve 9 is de-energized to prevent fuel (GAS) from entering the generator 10 at the same time.

[0055] When the fuel switching signal indicates that the current channel is transmitting fuel, the secondary pressure reducing solenoid valve is controlled to be de-energized and the fuel solenoid valve is energized to ensure that the current fuel transmission channel is: fuel (GAS) - fuel solenoid valve 9 - generator 10. In this process, the primary pressure reducing valve (LPG primary pressure reducing valve 2), the secondary pressure reducing solenoid valve (LPG / NG secondary pressure reducing solenoid valve 4), and the control solenoid valve (LPG / NG control solenoid valve 5) are all in a power-off state, that is, no liquefied petroleum gas (LPG) or natural gas (NG) is transmitted, avoiding liquefied petroleum gas (LPG) or natural gas (NG) from entering the generator 10 at the same time.

[0056] Accordingly, the corresponding solenoid valves in the multi-fuel generator set are controlled to be de-energized, including:

[0057] If the current channel transmits fuel (GAS), it means that only the fuel solenoid valve 9 in the current multi-fuel generator is in the energized state, while the first-level pressure reducing valve (LPG first-level pressure reducing valve 2), the second-level pressure reducing solenoid valve (LPG / NG second-level pressure reducing solenoid valve 4), and the control solenoid valve (LPG / NG control solenoid valve 5) are all in the de-energized state. Therefore, at this time, it is only necessary to control the fuel solenoid valve 9 to be de-energized to ensure that fuel (GAS) cannot enter when the generator 10 is shut down.

[0058] If the channel transmits liquefied petroleum gas (LPG), it means that the first-level pressure reducing valve (LPG first-level pressure reducing valve 2), the second-level pressure reducing solenoid valve (LPG / NG second-level pressure reducing solenoid valve 4) and the control solenoid valve (LPG / NG control solenoid valve 5) in the current multi-fuel generator are in an energized state, while the fuel solenoid valve 9 is de-energized. Therefore, at this time, the first-level pressure reducing valve (LPG first-level pressure reducing valve 2), the second-level pressure reducing solenoid valve (LPG / NG second-level pressure reducing solenoid valve 4) and the control solenoid valve (LPG / NG control solenoid valve 5) are de-energized, which can ensure that liquefied petroleum gas (LPG) cannot enter when the generator 10 is shut down.

[0059] If the channel transmits natural gas (NG), it means that the secondary pressure reducing solenoid valve 4 (LPG / NG secondary pressure reducing solenoid valve 4) and the control solenoid valve 5 (LPG / NG control solenoid valve 5) are in the energized state, and the fuel solenoid valve 9 is de-energized. Therefore, at this time, it is only necessary to control the secondary pressure reducing solenoid valve (LPG / NG secondary pressure reducing solenoid valve 4) and the control solenoid valve (LPG / NG control solenoid valve 5) to be de-energized to ensure that natural gas (NG) cannot enter when the generator 10 is shut down.

[0060] It should be noted that the embodiment provided in the present application is only one possible implementation method, but is not limited to only this implementation method and can be set according to the needs of the user.

[0061] The present application provides a method for controlling the on and off of a solenoid valve, in which the fuel transmission channel can be instantly cut off when the generator speed is detected to be zero, thereby preventing unburned fuel from being sucked into the muffler and causing explosion.

[0062] In addition, in order to ensure that the generator 10 is started or shut down under the instruction of the operator, the multi-fuel generator set control method further includes:

[0063] Determining whether a power signal indicating that power is turned on is received;

[0064] If a power signal is received, determining whether a start signal indicative of manual start is received;

[0065] If a start signal is received, the process proceeds to a step of acquiring a speed signal representing the speed of the generator in real time.

[0066] In a specific embodiment, in addition to connecting to a power source, the start-up of the generator 10 also requires the operator's instruction, that is, manual operation by the operator. That is, the generator can only be started after receiving a power signal and a start signal, and then enters the step of obtaining a speed signal representing the generator speed in real time.

[0067] It should be noted that there is no specific order between the determination of whether a power signal representing power-on is received and the determination of whether a start signal representing manual start is received, and they can be adjusted at any time.

[0068] It should also be noted that turning on the power supply specifically indicates that the battery 12 supplies power to the generator 10 , and when the generator 10 operates normally, the battery 12 is charged.

[0069] In addition, in order to reduce the power loss to a certain extent, when the target time when the generator speed is zero is greater than the preset sleep time, it enters the sleep state.

[0070] That is to say, the multi-fuel generator set control method provided in this application specifically includes the following steps:

[0071] Step 1: After receiving the power signal and the start signal, the generator 10 starts.

[0072] Step 2: When the generator 10 is detected to have a rotation speed, it will wake up immediately and control each solenoid valve to operate normally (charge the battery during its normal operation).

[0073] Step 3: When the fuel switching switch 6 selects the fuel (GAS) gear, the first-stage pressure reducing valve (LPG first-stage pressure reducing valve 2), the second-stage pressure reducing solenoid valve (LPG / NG second-stage pressure reducing solenoid valve 4), and the control solenoid valve (LPG / NG control solenoid valve 5) are all in a power-off state (closed), cutting off the LPG / NG supply, and the fuel solenoid valve 9 opens to supply GAS fuel.

[0074] When the fuel switching switch 6 selects the liquefied petroleum gas (LPG) gear, the first-stage pressure reducing valve (LPG first-stage pressure reducing valve 2), the second-stage pressure reducing solenoid valve (LPG / NG second-stage pressure reducing solenoid valve 4) and the control solenoid valve (LPG / NG control solenoid valve 5) are energized to provide LPG / NG supply, while the fuel solenoid valve 9 is closed to cut off the GAS fuel supply.

[0075] When the fuel switching switch 6 selects the natural gas (NG) gear, the secondary pressure reducing solenoid valve (LPG / NG secondary pressure reducing solenoid valve 4) and the control solenoid valve (LPG / NG control solenoid valve 5) are energized to provide LPG / NG supply, and the metering orifice of the control solenoid valve 5 is switched to the natural gas metering orifice. At the same time, the fuel solenoid valve 9 is closed to cut off the GAS fuel supply.

[0076] Step 4: The control module 13 detects that the generator 10 has no ignition speed signal (i.e. shutdown state) within 1 second. If the fuel switching switch 6 is in the GAS gear, the fuel solenoid valve 9 is closed to cut off the GAS fuel supply; if the switching switch is in the LPG or NG gear, the first-level pressure reducing valve (LPG first-level pressure reducing valve 2), the second-level pressure reducing solenoid valve (LPG / NG second-level pressure reducing solenoid valve 4), the control solenoid valve (LPG / NG control solenoid valve 5) and the fuel solenoid valve 9 are all closed to cut off all fuels to prevent the fuel output from causing the generator to explode when the engine is turned off. When the engine is abnormally turned off (i.e. the start switch 11 remains in the start gear after the engine is turned off), in order to prevent abnormal consumption of the battery 12, the control module 13 enters a dormant state after 60 seconds, thereby reducing the self-consumption of the battery 12.

[0077] In the above embodiments, the multi-fuel generator set control method is described in detail, and the present application also provides a corresponding embodiment of the multi-fuel generator set control device. It should be noted that the present application describes the embodiments of the device part from two perspectives, one is based on the functional module perspective, and the other is based on the hardware perspective.
