[0034] 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.

[0035] It should be noted that the terms "first", "second", "third" and "fourth" in the specification and claims of the present application are used to distinguish different objects rather than to describe a specific order. The terms "including" and "having" in the embodiments of the present application and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device including 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.

[0036] The embodiments of the present application disclose a power supply system, a power supply method, an electronic device and a computer-readable storage medium, which can actively consume the fuel in the fuel generator by supplying power jointly by the mains and the fuel generator, thereby avoiding fuel waste.

[0037] The technical solution of the present application will be described in detail below in conjunction with specific embodiments.

[0038] In order to more clearly explain the power supply logic of the power supply system disclosed in the embodiment of the present application, firstly, a power supply system architecture is introduced. Figure 1A , Figure 1A 1 is a schematic diagram of the architecture of a power supply system disclosed in an embodiment of the present application. The power supply system 100 may include N mains power supply circuits (N is a positive integer greater than or equal to 2) and a fuel generator 110. Different from the electricity generated by civil generators, mains power is an electric power resource extracted from the national power grid. It has the characteristics of low price and high stability, and is the main source of electricity for people's daily use. Figure 1A Only two mains power supply circuits are shown as examples: mains power supply circuit A 120A and mains power supply circuit B 120B. In fact, the number of mains power supply circuits provided in the power supply system can be set according to power supply requirements. Figure 1A The fuel generator may include but is not limited to: a diesel generator, an oil generator, a natural gas generator, etc., which can convert the heat energy generated by the fuel into electrical energy to supply power to the load.

[0039] Please refer again Figure 1A When switch 1 is closed, the power supply system 100 and the load 200 form a closed loop, and the power supply system 100 can provide power to the load 200. Optionally, under the premise that switch 1 is closed, switch 2 is closed, and power can be supplied to the load 200 through the A-line mains power supply circuit 120A; switch 3 is closed, and power can be supplied to the load 200 through the B-line mains power supply circuit 120B; and switches 4 and 5 are closed at the same time, and power can be supplied to the load 200 through the fuel generator. It can be understood that the control module of the power supply system 100 can control the mains power supply circuit and / or the fuel generator 110 to supply power to the load 200 by opening and closing the switches in the power supply system.

[0040] It needs to be further explained that Figure 1A This is only an example of a power supply system architecture. In fact, the power supply system may also include other components, such as a control module (e.g., a single-chip microcomputer, a computer), a fuel storage unit (e.g., an oil tank, a gas tank), and a sensor, which are not limited here. In addition, the components in the power supply system may also be connected in other ways. Figure 1A This should not be construed as limiting the embodiments of the present application.

[0041] In some embodiments, in order to more clearly explain the control logic of the power supply system disclosed in the embodiments of the present application, a control module applicable to the power supply system is first introduced. Figure 1B , Figure 1B 3001 , a generator control unit 3002 , and a fuel control unit 3003 .

[0042] Among them, when the AC power control unit 3001 receives the first power supply signal (the first power supply signal can be input by the user, or generated by the control module when it detects that the fuel is about to expire, and is used to indicate that the load is powered by the AC power supply circuit and the fuel generator), it can send a signal to start the combined power supply to the generator control unit 3002 and the fuel control unit 3003 respectively; the generator control unit 3002 can respond to the signal to start the combined power supply, start the fuel generator and send a signal to the AC power control unit 3001 and the fuel control unit 3003 respectively that the generator has completed starting; further, after receiving the signal to start the combined power supply and the signal that the generator has completed starting, the fuel control unit can control the fuel storage unit (for example: oil tank, gas tank, etc.) to deliver fuel to the fuel generator; and when the AC power control unit 3001 receives the signal that the generator has completed starting, it can control M of the N AC power supply circuits to be disconnected, and control the AC power supply circuits that are not disconnected in the N AC power supply circuits to supply power to the load together with the fuel generator, where M is a positive integer greater than or equal to 1, and M is less than N.

[0043] Furthermore, when the fuel control unit 3003 detects that the fuel generator has completed the fuel update, it can send a signal that the fuel update is completed to the AC power control unit 3001 and the generator control unit 3002 respectively; when the AC power control unit 3001 receives the signal that the fuel update is completed, it can control the M-way AC power supply circuit to be reconnected, and send a signal to the generator control unit 3002 to shut down the generator; and then, when the generator control unit 3002 receives the signal that the fuel update is completed and the signal to shut down the generator, it can shut down the generator.

[0044] In another embodiment, the structure of the control module can also be as follows Figure 1C As shown, Figure 1C It is a structural diagram of another control module disclosed in an embodiment of the present application. The control module 300 may include a mains power control unit 3001, a generator control unit 3002, and a fuel control unit 3003. In addition, the power supply system may further include a signal exchange unit 3004 (for example, a switch). Among them, the signal exchange unit 3004 may be connected to the mains power control unit 3001, the generator control unit 3002, and the fuel control unit 3003, respectively, and then the signal exchange unit 3004 may forward the signal sent by the connected control units to realize communication between the above-mentioned control units (optionally, the control units may communicate via TCP / IP (Transmission Control Protocol / Internet Protocol, which is not limited here).

[0045] It is understandable that in adopting Figure 1CWhen using the control module shown in the figure, the AC power control unit 3001, the generator control unit 3002 and the fuel control unit 3003 can also implement the signal transmission method introduced above. For example, when the AC power control unit 3001 receives the first power supply signal, it can send a signal to the signal exchange unit 3004 to start the joint power supply, and then the signal exchange unit 3004 can forward the signal to start the joint power supply to the generator control unit 3002 and the fuel control unit 3003 respectively, which will not be repeated here.

[0046] It needs to be further explained that Figure 1B and Figure 1C The structure of the control module is shown only as an example. In fact, the control module may also include other control units, such as a fuel volume monitoring unit, a fuel expiration monitoring unit, etc., which are not limited here. The control units included in the control module may also communicate through other architectures. Figure 1B and Figure 1C This should not be construed as limiting the embodiments of the present application.

[0047] See also Figure 2 , Figure 2 2 is a schematic diagram of a power supply system disclosed in an embodiment of the present application. The power supply system may include N mains power supply circuits 202, a control module 204, and a fuel generator 206, where N is a positive integer greater than or equal to 2.

[0048] The N-channel mains power supply circuit 202 is used to supply power to the load via the mains.

[0049] In the embodiment of the present application, the mains power supply circuit is a circuit for supplying mains power to a load (various electrical equipment). The input end of the mains power supply circuit may be a power grid provided by the state, and the output end may be a load. Among them, since the mains power is an electric power resource provided by the state power grid, it has the characteristics of high power supply stability and high cost performance. Therefore, the mains power is used as the main power supply means to supply power to the load, which can ensure the normal operation of the load and save costs.

[0050] Optionally, N mains power supply circuits can be connected to the load individually, so as to facilitate the individual control of different mains power supply circuits to power the load, or only power the corresponding load through certain mains power supply circuits, which is not limited here.

[0051] The control module 204 is used to receive a first power supply signal, and control the fuel generator 206 to start according to the first power supply signal, and control M mains power supply circuits in the N mains power supply circuits 202 to disconnect, where M is a positive integer greater than or equal to 1 and M is less than N.

[0052] In the embodiment of the present application, the first power supply signal is used to indicate that the load is supplied with power by the mains power supply circuit and the fuel generator. The first power supply signal can be an external signal received by the control module (for example, a controller connected to the control module in communication, a first power supply signal input by an input port (for example, a button) connected to the control module. Optionally, the input port can include multiple modes such as manual mode and automatic mode for the user to choose. When the user selects the manual mode at the input port, the input port can generate a first power supply signal and send it to the control module; and when the user selects the automatic mode at the input port, the input port can generate an automatic control signal to the control module, and then the control module can automatically control the mains power supply circuit and / or the fuel generator to supply power according to the state of the power supply system (including the state of the mains power supply circuit, the state of the fuel generator, etc.), or it can be generated by the control module when it detects that the conditions for joint power supply are met (for example, when the load of the mains power supply circuit is too large, it is determined that the conditions for joint power supply are met, and when the stored fuel is about to expire, it is determined that the conditions for joint power supply are met, etc.), which is not limited here.

[0053] In practice, it is found that although the power supply stability of the mains is very high, it is inevitable that there will still be situations where the power supply cannot be supplied normally. In order to ensure the normal power supply to the load, the power supply system can be provided with a fuel generator, which is used as an alternative means to supply power to the load when the mains cannot supply power to the load normally. In this regard, in the relevant technology, the fuel generator will only start to generate electricity when the mains power supply circuit cannot supply power normally. Therefore, if the mains power supply circuit can supply power stably, the fuel generator will not start for a long time. It is understandable that fuels such as diesel and gasoline have an expiration date, so if the fuel generator is not started for a long time, it may cause the fuel in the fuel generator to expire, which in turn leads to fuel waste.

[0054] Optionally, the control module 204 can control the fuel generator 206 to start according to the first power supply signal when receiving the first power supply signal, so that the fuel generator can be actively started to consume the fuel in the fuel generator to prevent the fuel from being wasted due to expiration. Further, considering that the fuel generator may fail or run out of fuel during the power generation process and interrupt the power supply to the load, the control module 204 can optionally control only M (M is a positive integer greater than or equal to 1, and M is less than N) of the N-way mains power supply circuits 202 to disconnect, rather than disconnecting all the N-way mains power supply circuits. For example: if the power supply system is provided with a total of 2 mains power supply circuits, one of them can be disconnected; for another example: if the power supply system is provided with a total of 3 mains power supply circuits, one or two of them can be disconnected, which is not limited here. Optionally, the disconnected M-way mains power supply circuits can be specified by the user or developer, or can be determined by the control module based on the power supply stability of the N-way mains power supply circuits, which is not limited here.

[0055] Furthermore, the subsequent control module 204 can control the undisconnected AC power supply circuit and the fuel generator to jointly supply power to the load. Compared with using the fuel generator alone to power the load, using the AC power supply circuit and the fuel generator to jointly supply power to the load can better ensure the stability of power supply.

[0056] The fuel generator 206 is used to supply power to the load together with the mains power supply circuits that are not disconnected in the N mains power supply circuits 202 .

[0057] In the embodiment of the present application, the fuel generator 206 may include a diesel generator, a natural gas generator, etc., which are not limited here. It is understood that the fuel generator can generate heat by burning fuel and generate electrical energy through a series of conversion processes. Since the fuel generator is small in size, cheap and easy to operate, it can be used as a backup power supply to power the load.

[0058] As described above, in the embodiment of the present application, the fuel generator is no longer passively started as a passive solution when the mains power supply circuit fails to supply power normally. Instead, it can be actively started by the control module 204, so that the fuel in the fuel generator can be actively consumed to prevent fuel waste. In addition, by controlling the mains power supply circuit that is not disconnected to supply power to the load together with the fuel generator, the stability of the power supply can be ensured while consuming the fuel in the fuel generator.

[0059] The power supply system disclosed in the above-mentioned embodiments can consume the fuel stored in the fuel generator by actively starting the fuel generator to avoid waste caused by expired fuel. In addition, compared with using a fuel generator alone to power the load, using the mains power supply circuit and the fuel generator to power the load together can better ensure the stability of power supply. In addition, the power supply system can also disconnect certain mains power supply circuits when the load of the mains power supply circuit is too large, and supply power to the load together through the mains power supply circuit that is not disconnected and the fuel generator, so as to relieve the pressure on the mains power supply circuit, thereby protecting the mains power supply circuit.

[0060] See also Figure 3 , Figure 3 2 is a schematic diagram of another power supply system disclosed in an embodiment of the present application. The power supply system may include N mains power supply circuits 202, a control module 204, and a fuel generator 206, where N is a positive integer greater than or equal to 2, and the control module 204 may include a mains control unit 2041, a generator control unit 2042, and a fuel control unit 2043. Among them:

[0061] N-channel mains power supply circuit 202, used to supply power to the load via the mains;

[0062] In one embodiment, the N-way mains power supply circuit 202 may also be a power supply circuit of other energy sources, such as a solar generator power supply circuit, a wind generator power supply circuit, etc. When the power supply circuit of other energy sources cannot supply power normally due to a fault or at a peak power consumption, the fuel generator may be started to assist in power supply. In addition, the fuel generator and the power supply circuit of other energy sources may also be actively started to jointly supply power to the load to consume the fuel in the fuel generator to avoid fuel waste, which is not limited here.

[0063] The control module 204 is used to receive the first power supply signal, and control the fuel generator to start according to the first power supply signal, and control M mains power supply circuits among the N mains power supply circuits to be disconnected, where M is a positive integer greater than or equal to 1, and M is less than N;

[0064] The fuel generator is used to supply power to the load together with the mains power supply circuit that is not disconnected among the N mains power supply circuits.

[0065] The power supply voltage output by the fuel generator to the load may be equal to the power supply voltage output by the M-way power supply circuit to the load before being disconnected. Thus, after the M-way power supply circuit is disconnected, the power supply voltage provided by the power supply system to the load remains unchanged, thereby ensuring the normal operation of the load.

[0066] In one embodiment, the first power supply signal may be a control signal sent to the control module 204 by a user, control module 204 or other electronic device when it determines that the difference between the current moment and the validity period corresponding to the fuel stored in the fuel generator is less than or equal to a time threshold (the specific value may be set by a developer based on a large amount of development data, for example: one week, two weeks, etc., which is not limited here).

[0067] In another embodiment, the first power supply signal may be a control signal sent to the control module 204 by the user, the control module 204 or other electronic device when it is determined that some or all of the N mains power supply circuits are in an abnormal state. Thus, when some or all of the mains power supply circuits cannot supply power normally due to a fault, the fuel generator may be started to provide power to maintain the power supply voltage of the power supply system.

[0068] In another embodiment, the first power supply signal may be a control signal sent to the control module 204 by the user, the control module 204 or other electronic devices when it is determined that the N-way mains power supply circuit is in the peak power transmission period (optionally, when it is detected that the power grid that provides power to the N-way mains power supply circuit outputs more power than the power threshold value (the specific value can be set by the developer based on a large amount of development data, which is not limited here) per unit time (per minute, per hour, etc.), it can be determined that the N-way mains power supply circuit is in the peak power transmission period. It can also be determined that the N-way mains power supply circuit is in the peak power transmission period when a warning message indicating the peak power transmission period is received from the corresponding server of the power grid, which is not limited here). Thus, when the mains power supply circuit is in the peak power transmission period, some mains power supply circuits can be disconnected, and the load can be powered by the mains power supply circuit that is not disconnected and the fuel generator to relieve the pressure on the mains power supply circuit, thereby protecting the mains power supply circuit.

[0069] In another embodiment, the first power supply signal may be a control signal sent to the control module 204 by the user, the control module 204 or other electronic device when determining that the power supply system is in a power cutover state. The power cutover state includes a state where the lines in the power supply system are under maintenance, because when in the power cutover state, the mains power supply circuit and / or the power supply line of the fuel generator may not be able to supply power normally due to interruption. The first power supply signal is generated for this purpose, so that the power supply system supplies power to the load through the mains power supply circuit and the fuel generator, and when one side of the mains power supply circuit or the fuel generator is interrupted during the power cutover process, it can be ensured that one side can supply power to the load, thereby ensuring the normal operation of the load.

[0070] As an optional implementation, the control module 204 is further used to obtain the power supply stability of each of the N mains power supply circuits. The power supply stability can be a proportional value determined by the control module 204 for the state of the mains power supply circuit (for example, the voltage tolerance of the power supply circuit, whether it is in a fault state, etc.), which is used to indicate the probability that the mains power supply circuit can supply power normally in the future for a period of time (for example, one hour, one day, etc., not limited here).

[0071] Furthermore, the control module 204 can determine M mains power supply circuits from the N mains power supply circuits according to the power supply stability corresponding to each mains power supply circuit. The power supply stability of the M mains power supply circuit is lower than that of other mains power supply circuits in the N mains power supply circuits except the M mains power supply circuit.

[0072] Optionally, the control module 204 is further configured to select the mains power supply circuits with the first M power supply stability from the N mains power supply circuits in the order of power supply stability from low to high.

[0073] By implementing the above power supply system, the control module can determine M mains power supply circuits with poor power supply stability among N mains power supply circuits according to the power supply stability of each mains power supply circuit, and subsequently disconnect the M mains power supply circuits with poor power supply stability to ensure that the mains power supply circuits that are still connected can supply power more stably.

[0074] As an optional implementation, the control module 204 is further configured to receive a first power supply signal, and if it is determined that the fuel currently stored in the fuel generator is within the effective shelf life, control the fuel generator to start according to the first power supply signal.

[0075] The effective shelf life indicates the period during which the corresponding fuel can be used safely, for example, 3 years, 5 years, etc., which are not limited here. The effective shelf life corresponding to the effective shelf life is the production date of the fuel plus the effective shelf life. For example, if the production date of the fuel is July 1, 2021 and the effective shelf life is 3 years, then the effective shelf life of the fuel is July 1, 2024. Optionally, if the current date is before July 1, 2024, it can be determined that the fuel currently stored in the fuel generator is within the effective shelf life.

[0076] It is understandable that in another embodiment, the control module 204 is also used to control the fuel generator to start up not according to the first power supply signal if it is determined that the fuel stored in the fuel generator is not within the effective shelf life period after receiving the first power supply signal. Because if the fuel stored in the fuel generator is not within the effective shelf life period, it means that the fuel has expired. In order to avoid the fuel generator from being damaged by burning expired fuel, the fuel generator may not be controlled to start up according to the first power supply signal.

[0077] When the power supply system described above is implemented and the first power supply information is received, it can first be determined whether the fuel stored in the fuel generator is expired. If the fuel is not expired, the fuel generator is controlled to start, thereby avoiding damage to the fuel generator due to burning expired fuel.

[0078] Considering that it is impossible for the user to always pay attention to whether the fuel stored in the fuel generator is expired, and then actively input the first power supply signal to start the fuel generator to consume fuel. Optionally, the control module 204 is also used to control the fuel generator to start and control the M mains power supply circuits in the N mains power supply circuits to disconnect when it is detected that the current moment is within the effective shelf life corresponding to the fuel stored in the fuel generator, and the difference between the current moment and the effective shelf life corresponding to the effective shelf life is less than or equal to the time threshold (the specific value can be set by the developer based on a lot of development experience, such as one week or two weeks, which is not limited here), where M is a positive integer greater than or equal to 1, and M is less than N.

[0079] By implementing the above-mentioned power supply system, the control module can automatically monitor whether the fuel stored in the fuel generator is expired, and start the fuel generator to consume the fuel before the fuel is about to expire, thereby avoiding waste caused by expired fuel and improving the intelligence of the power supply system.

[0080] Optionally, the control module 204 is also used to control the disconnected M-way AC power supply circuit to be reconnected and control the fuel generator to be shut down when it is detected that the fuel generator 206 has completed fuel renewal and / or a control signal to shut down the generator is detected.

[0081] In the embodiment of the present application, the fuel generator 206 may include a fuel storage unit, such as an oil tank, a gas tank, etc., which are not limited here. Optionally, the control module 204 may determine that the fuel generator 206 completes the fuel update when it detects that the volume of the fuel stored in the fuel storage unit is less than or equal to a volume threshold (the volume threshold may be roughly the volume of the remaining fuel when the fuel stored in the fuel storage unit is exhausted. The specific value may be set by the developer based on a large amount of development data, such as 0 liters, 0.1 liters, which are not limited here), that is, when the fuel stored in the fuel storage unit is exhausted.

[0082] It can be understood that when it is determined that the fuel generator 206 has completed the fuel update, the goal of consuming the fuel that is about to expire has actually been achieved. In order to save costs and ensure the stability of power supply, the control module 204 can control the disconnected M-way AC power supply circuit to be reconnected (it can be understood that a switch is provided in the AC power supply circuit. When the switch is turned on, the AC power supply circuit is disconnected; when the switch is closed, the AC power supply circuit is reconnected) and control the fuel generator to shut down.

[0083] Optionally, considering that it may take a certain amount of time to reconnect the AC power supply circuit, the control module 204 can control the disconnected M-way AC power supply circuit to be reconnected, and only control the fuel generator to be shut down after determining that the M-way AC power supply circuit has been reconnected, so as to avoid the situation where the M-way AC power supply circuit has not been reconnected during the period when the fuel generator is shut down, resulting in insufficient power supply voltage.

[0084] In another embodiment, the control module 204 may control the disconnected M-way mains power supply circuit to be reconnected and control the fuel generator to be turned off when a control signal for turning off the generator is detected. Optionally, the control signal for turning off the generator may be input by a user or generated by the control module 204, for example, when the fuel generator 206 is detected to be in an abnormal state, and is used to turn off the fuel generator to prevent the generator 206 in the abnormal state from continuing to work and being damaged.

[0085] In another embodiment, the control module 204 may control the disconnected M-way mains power supply circuit to be reconnected and control the fuel generator to be shut down when it is detected that the fuel generator 206 has completed fuel renewal and a control signal to shut down the generator is detected.

[0086] As an optional embodiment, the control module 204 is also used to control the fuel adding device (such as a gas gun, an air filling gun, etc., not limited here) to add fuel to the fuel storage unit of the fuel generator when it is detected that the fuel generator 206 has completed fuel updating.

[0087] In another embodiment, the control module 204 is further used to output a first prompt message when it is detected that the fuel generator 206 has completed the fuel update. The first prompt message is used to prompt the user to change the fuel or add fuel to the fuel storage unit of the fuel generator, which is not limited here.

[0088] In one embodiment, the AC power control unit 2041 may be configured to receive a first power supply signal and send a start signal to the generator control unit according to the first power supply signal.

[0089] The start signal is used to notify the generator control unit to control the start of the fuel generator.

[0090] The generator control unit 2042 can be used to control the start of the fuel generator in response to the start signal sent by the mains control unit 2041.

[0091] In another embodiment, the generator control unit 2042 is further used to send a start-up completion signal to the mains power control unit 2041 when the fuel generator is started up;

[0092] The mains power control unit 2041 is further configured to control the disconnection of M mains power supply circuits among the N mains power supply circuits in response to the completion start signal.

[0093] Among them, considering that the startup process of the fuel generator takes a certain amount of time, in order to avoid the idle period before the fuel generator is started, the mains control unit 2041 controls the M-way mains power supply circuit in the N-way mains power supply circuit to be disconnected in advance, resulting in insufficient power supply voltage. The mains control unit 2041 can control the M-way mains power supply circuit in the N-way mains power supply circuit to be disconnected only when it is determined that the fuel generator has been started, so as to ensure the stability of the power supply voltage provided to the load, thereby ensuring the normal operation of the load.

[0094] As an optional implementation, the fuel generator 206 may include a fuel storage unit, and further, the mains control unit 2041 may also be configured to send a fuel supply signal to the fuel control unit 2043 according to the first power supply signal when receiving the first power supply signal;

[0095] The fuel control unit 2043 is used to control the fuel storage unit to deliver fuel to the fuel generator in response to the fuel supply signal sent by the mains control unit 2041.

[0096] Optionally, the fuel generator 206 may include multiple fuel storage units (e.g. Figure 4 As shown, the fuel storage unit may include oil tank 1 and oil tank 2, and oil tank 1 and oil tank 2 may be connected to the fuel generator to provide fuel for the fuel generator. In other embodiments, the fuel storage units may be 3, 5 or 6, etc., which are not limited here. Optionally, the fuel control unit 2043 may also be used to obtain the usage order of the multiple fuel storage units; and control the multiple fuel storage units to sequentially deliver fuel to the fuel generator according to the usage order.

[0097] The order of use of the multiple fuel storage units may be set by the user or by the fuel control unit 2043, which is not limited here. The order of use may include: order from small to large according to the number of the fuel storage units, order from short to long according to the difference between the current time and the expiration date of the fuel stored in the fuel storage unit, etc., which is not limited here.

[0098] By implementing the above power supply system, fuel with a short validity period can be consumed first, so that when the fuel generator fails to consume all the fuel at once, the fuel with a short validity period can be consumed as much as possible, avoiding the waste of the fuel with a short validity period due to expiration after being left for a period of time.

[0099] In one embodiment, the usage order may be based on the type of fuel stored in the fuel storage unit and the order of compatibility with the operating temperature of the fuel generator from high to low.

[0100] It is understandable that according to the different applicable temperatures, diesel can be divided into: "0#", "-10#" and "-20#" models of diesel. Among them, "0#" model diesel is suitable for temperatures above 4 degrees Celsius, "-10#" model diesel is suitable for temperatures between 4 degrees Celsius and 5 degrees Celsius, and "-20#" model diesel is suitable for temperatures between -5 degrees Celsius and -14 degrees Celsius.

[0101] Optionally, the fuel control unit 2043 can also be used to obtain the operating temperature of the fuel generator and determine the usage order of multiple fuel storage units based on the operating temperature of the fuel generator, wherein the usage order can be based on the model of the fuel stored in the fuel storage unit and the order of compatibility with the operating temperature of the fuel generator from high to low.

[0102] For example, if the operating temperature of the fuel generator is 6 degrees Celsius, you can use the "0#" model diesel first, then the "-10#" model diesel, and finally the "-20#" model diesel.

[0103] By implementing the above power supply system, fuel that has a high degree of matching with the operating temperature of the fuel generator can be consumed preferentially, thereby improving the combustion efficiency of the fuel generator and further improving the power generation efficiency of the fuel generator.

[0104] In one embodiment, the fuel control unit 2043 may also be used to send an update completion signal to the mains control unit 2041 and the generator control unit 2042 respectively when it is detected that the volume of the fuel stored in the fuel generator 206 is less than a volume threshold (the volume threshold may be roughly the volume of the remaining fuel when the fuel stored in the fuel storage unit is exhausted. The specific value may be set by the developer based on a large amount of development data, such as 0 liters, 0.1 liters, which is not limited here);

[0105] The mains power control unit 2041 is further used to control the M mains power supply circuits to reconnect in response to the update completion signal;

[0106] The generator control unit 2042 is further used to control the fuel generator to shut down in response to the update completion signal.

[0107] The power supply system disclosed in the above-mentioned embodiments can consume the fuel stored in the fuel generator by actively starting the fuel generator to avoid waste caused by expired fuel. In addition, compared with using a fuel generator alone to power the load, using the mains power supply circuit and the fuel generator to power the load together can better ensure the stability of power supply. In addition, the power supply system can also disconnect certain mains power supply circuits when the load of the mains power supply circuit is too large, and supply power to the load together through the mains power supply circuit that is not disconnected and the fuel generator, so as to relieve the pressure on the mains power supply circuit, thereby protecting the mains power supply circuit.

[0108] See also Figure 5 , Figure 5 1 is a flow chart of a power supply method disclosed in an embodiment of the present application. The power supply method can be applied to the control module included in the above-mentioned power supply system, and the power supply system also includes N mains power supply circuits and a fuel generator, and the N mains power supply circuits are used to supply power to the load through the mains, and N is a positive integer greater than or equal to 2. The method may include the following steps:

[0109] 502. Receive a first power supply signal, and control the fuel generator to start according to the first power supply signal.

[0110] As an optional implementation, when the control module receives the first power supply signal, if it is determined that the fuel currently stored in the fuel generator is within the valid shelf life, the control module controls the fuel generator to start according to the first power supply signal.

[0111] By implementing the above method, when receiving the first power supply information, it can be determined whether the fuel stored in the fuel generator is expired. If the fuel is not expired, the fuel generator is controlled to start, so as to avoid the fuel generator being damaged by burning expired fuel.

[0112] As another optional embodiment, the control module can control the fuel generator to start and control M of the N AC power supply circuits to disconnect when it detects that the current moment is within the effective shelf life corresponding to the fuel stored in the fuel generator, and the difference between the current moment and the validity period corresponding to the effective shelf life is less than or equal to the duration threshold.

[0113] By implementing the above method, it is possible to automatically monitor whether the fuel stored in the fuel generator is expired, and start the fuel generator to consume the fuel before the fuel is about to expire, thereby avoiding waste caused by expired fuel and improving the intelligence of the power supply system.

[0114] As an optional embodiment, the fuel generator includes a plurality of fuel storage units. Then, the control module can start the fuel generator according to the first power supply signal, and obtain the use order of the plurality of fuel storage units; and control the plurality of fuel storage units according to the use order to sequentially deliver fuel to the fuel generator.

[0115] By implementing the above method, fuel with a short validity period can be consumed first, so that when the fuel generator fails to consume all the fuel at once, the fuel with a short validity period can be consumed as much as possible to avoid the waste of the fuel with a short validity period due to expiration after being left for a period of time.

[0116] 504. Control M mains power supply circuits among N mains power supply circuits to be disconnected, and control the fuel generator and the mains power supply circuits that are not disconnected among the N mains power supply circuits to jointly supply power to the load, where M is a positive integer greater than or equal to 1, and M is less than N.

[0117] In the embodiment of the present application, the power supply voltage output by the fuel generator to the load is equal to the power supply voltage output by the M-way power supply circuit to the load before being disconnected. Thus, it can be ensured that after the M-way power supply circuit is disconnected, the power supply voltage provided to the load by the power supply system remains unchanged, thereby ensuring the normal operation of the load.

[0118] As an optional implementation, after the control module controls the fuel generator and the undisconnected AC power supply circuit in the N-way AC power supply circuit to jointly supply power to the load, if it detects that the fuel generator has completed fuel update and / or detects a control signal to shut down the generator, it can control the M-way AC power supply circuit to be reconnected and control the fuel generator to shut down.

[0119] As an optional implementation, the control module may determine that the fuel generator has completed fuel renewal upon detecting that the volume of the fuel stored in the fuel generator is less than a volume threshold.

[0120] By implementing the above method, when it is determined that the fuel generator has completed fuel renewal, the disconnected M-way AC power supply circuit can be controlled to be reconnected, thereby saving costs and ensuring the stability of power supply; and when it is detected that the fuel generator is in an abnormal state, the fuel generator is shut down to prevent the generator in the abnormal state from continuing to work and being damaged.

[0121] As an optional implementation, the control module can obtain the power supply stability of each of the N mains power supply circuits; then, according to the power supply stability corresponding to each of the mains power supply circuits, M mains power supply circuits are determined from the N mains power supply circuits, wherein the power supply stability of the M mains power supply circuits is lower than that of other mains power supply circuits except the M mains power supply circuit in the N mains power supply circuits. Then, the control module can control the M mains power supply circuits to be disconnected.

[0122] Optionally, the control module may select the mains power supply circuits with the first M power supply stability from the N mains power supply circuits in order of power supply stability from low to high.

[0123] By implementing the above method, M mains power supply circuits with poor power supply stability can be determined among N mains power supply circuits according to the power supply stability of each mains power supply circuit, and the M mains power supply circuits with poor power supply stability can be disconnected subsequently to ensure that the mains power supply circuits that are still connected can provide power more stably.

[0124] By implementing the methods disclosed in the above embodiments, the fuel stored in the fuel generator can be consumed by actively starting the fuel generator to avoid waste caused by expired fuel. In addition, compared with using a fuel generator alone to power the load, using a mains power supply circuit and a fuel generator to power the load together can better ensure the stability of power supply. In addition, the power supply system can also disconnect certain mains power supply circuits when the load of the mains power supply circuit is too large, and supply power to the load together through the mains power supply circuit that is not disconnected and the fuel generator, so as to relieve the pressure on the mains power supply circuit, thereby protecting the mains power supply circuit.
