Detailed ways

In order to make the purpose, technical solutions and advantages of the present invention more clear, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention. , not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

Figure 1 is one of the flow diagrams of a method for controlling the operating mode of an air conditioner based on load provided by the present invention.

In order to further introduce the method for controlling the operating mode of the air conditioner based on the load provided by the present invention, the following will be described in conjunction with FIG. 1 .

In an exemplary embodiment of the present invention, as can be seen with reference to FIG. 1 , a method for controlling the operating mode of an air conditioner based on load may include steps 110 to 130 , and each step will be introduced separately below.

In step 110, when the mains power grid does not provide normal power supply, the air conditioner is controlled to operate according to the lowest operating power gear of the energy-saving mode.

In step 120, when the air conditioner is operating at the lowest operating power level, the total power supply current in the unit space and the total load current of the additional power-consuming appliances in the unit space are monitored in real time.

In one embodiment, the total power supply current and the total load current can be monitored in real time based on the signal receiving module. Among them, the signal receiving module can be connected to the input terminal of the standing power supply, so that the total power supply current in the unit space can be obtained based on the current value flowing into the input terminal of the standing power supply. The signal receiving module can also be connected to the output terminal of the standing power supply, so that the total load current in the unit space can be obtained based on the current value flowing out of the output terminal of the standing power supply. Among them, the source of standing power can be community power generation, mains power grid, and personal generators.

In step 130, based on the total power supply current and the total load current, the target operating power gear of the air conditioner in the energy-saving mode is determined, and the air conditioner is controlled to operate according to the target operating power gear.

Among them, the additional power-consuming appliances are other appliances in the unit space except air conditioners, such as lights, televisions, refrigerators, etc. The unit space may be a space formed by the user's home as a unit.

In one embodiment, the power supply of the air conditioner can come from an indoor standing power socket, where the indoor standing power socket can provide power based on commercial power to ensure continuous and effective operation of the air conditioner. When the mains power grid does not provide normal power, it means that the air conditioner may not be able to operate according to the preset mode. If the operating mode of the air conditioner is not adjusted in time, there is a risk that the air conditioner will shut down due to current limitation.

During the application process, when it is detected that the mains power grid is not supplying normal power, the air conditioner can be automatically controlled to operate at the lowest operating power level in the energy-saving mode. Among them, the operation of the air conditioner according to the lowest operating power gear means that the outdoor unit of the air conditioner operates according to the lowest operating power gear.

It is understandable that when the mains power grid fails to work properly, users can also obtain power through other methods, such as community generators or small household generators for compensation. In addition, if the total load power consumption per unit space is small, it is not necessary to operate the air conditioner at the lowest operating power level, which will not be able to effectively meet the individual needs of users.

During the application process, when the air conditioner operates at the lowest operating power level, the total power supply current L0 in the unit space and the total load current L1 of the additional power-consuming appliances in the unit space can be further monitored in real time. Then based on the total power supply current L0 and the total load current L1, the target operating power level of the air conditioner in the energy-saving mode is determined, and the air conditioner is controlled to operate according to the target operating power level.

It should be noted that the target operating power level can be individually determined based on the current actual temperature conditions on the premise that the total available current is not exceeded, so that the air conditioner will not shut down due to current limitation. Under the premise, the target operating power level of the air conditioner in the energy-saving mode is personalized according to the electrical load per unit space to improve the user's experience and satisfaction during use.

In yet another exemplary embodiment of the present invention, the following methods may be used to determine that the mains power grid is not supplying power normally:

Determine the reception status of the representation signal received by the signal receiving module, wherein the signal receiving module has the ability to receive the representation signal; the representation signal is sent by the signal sending module, the signal sending module is powered by the mains power grid, and the representation signal is a preset frequency band signal;

When the signal receiving module does not receive the characterization signal, it is determined that the mains power grid is not supplying power normally.

In one embodiment, when the signal sending module is powered normally, the signal transmission between the signal sending module and the signal receiving module can also be carried out through wireless signal transmission, including but not limited to Wifi, NB-IOT, LoRa, ZigBee. The signal sending module transmits the characterization signal, and the signal receiving module receives the characterization signal. The two transmit through wireless signals, which can realize multi-node control, wide coverage, low power consumption, small impact of power grid operation fluctuations, and avoid voltage fluctuations of the characterization signal. The influence causes signal transmission distortion, which can realize the transmission of characteristic signals independently of the operating conditions of the power grid.

In one embodiment, the signal receiving module may be installed next to the indoor unit of the air conditioner or built inside the indoor unit. Wherein, the power source of the signal receiving module can be the power source from the indoor unit, and there is a signal line connecting the signal receiving module and the computer board of the indoor unit, so that the signal can be transmitted to the indoor unit based on the signal receiving module.

In another embodiment, when the mains power grid can provide normal power supply to the signal sending module, the signal sending module may have the ability to transmit the characterization signal. In other words, the signal sending module is powered by the mains power grid. If the mains power grid can supply power to it, the signal sending module can send out the representation signal. Furthermore, since the signal receiving module has the ability to receive the characterization signal, when the signal sending module can transmit the characterization signal, the signal receiving module can receive the characterization signal. And because when the mains power grid provides normal power supply to the signal sending module, in other words, when the mains power grid can provide normal power supply to the electrical appliances, in this scenario, the signal receiving module can receive the representation signal. When the mains power grid cannot provide normal power supply to the signal sending module, in other words, when the mains power grid cannot provide normal power supply to the electrical appliances, in this scenario, the signal receiving module cannot receive the representation signal.

Based on this, it can be determined whether the mains power grid is supplying power normally based on the reception of the representative signal received by the signal receiving module. In an example, when the signal receiving module does not receive the characterization signal, it is determined that the mains power grid is not supplying power normally. Through this embodiment, it can be automatically determined whether the mains power grid is supplying power normally at a lower cost.

The method for controlling the operating mode of the air conditioner based on the load provided by the invention controls the air conditioner to operate in the lowest operating power gear of the energy-saving mode when the mains power grid does not provide normal power; when the air conditioner operates in the lowest operating power gear In the case of real-time monitoring of the total power supply current in the unit space and the total load current of the additional power-consuming appliances in the unit space; based on the total power supply current and the total load current, determine the target operating power level of the air conditioner in the energy-saving mode , and controls the air conditioner to operate according to the target operating power gear, thereby realizing the personalized adjustment of the target operating power of the air conditioner in the energy-saving mode according to the electrical load per unit space without the air conditioner shutting down due to current limitation. gears to improve user experience and satisfaction during use.

Figure 2 is a schematic flowchart of determining the target operating power level of the air conditioner in the energy-saving mode based on the total power supply current and the total load current provided by the present invention.

The process of controlling the operating mode of the air conditioner based on the load will be described below with reference to Figure 2.

In an exemplary embodiment of the present invention, based on the total power supply current and the total load current, determining the target operating power level of the air conditioner in the energy-saving mode may include steps 210 to 230, each of which will be introduced below. step.

In step 210, the total available current is determined based on the difference between the total supply current and the total load current.

In step 220, based on the total available current, a maximum operating power value corresponding to the available total current is determined.

In step 230, based on the maximum operating power value, the target operating power gear of the air conditioner in the energy-saving mode is determined.

Among them, the target operating power value corresponding to the target operating power gear is less than or equal to the maximum operating power value.

In one embodiment, the total current L0 of the power supply (corresponding to the total power supply current) and the power consumption current L1 of other electrical appliances (corresponding to the total load current) can be monitored based on the signal receiving module. Further, based on the difference between the total power supply current L0 and the total load current L1, it is determined that the available total current L2=L0-L1.

It can be understood that the maximum current that the air conditioner can operate is L2, and the maximum operating power value can be determined based on the maximum current L2 that can operate. In other words, the operating power of the air conditioner must be less than or equal to the maximum operating power value.

In yet another embodiment, the target operating power level of the air conditioner in the energy-saving mode can be determined based on the maximum operating power value, thereby ensuring that the air conditioner will not shut down due to current limitation. The electric load can personalizedly adjust the target operating power level of the air conditioner in energy-saving mode to improve the user's experience and satisfaction during use. During the application process, the target operating power level will also be determined individually based on the outside temperature, so that the final target operating power level will not exceed the maximum operating power value and can be personalized with the outside temperature.

Figure 3 is a schematic flowchart of determining the target operating power gear of the air conditioner in the energy-saving mode based on the maximum operating power value provided by the present invention.

The process of determining the target operating power level of the air conditioner in the energy-saving mode based on the maximum operating power value will be further introduced below in conjunction with Figure 3.

In an exemplary embodiment of the present invention, based on the maximum operating power value, determining the target operating power level of the air conditioner in the energy-saving mode may include steps 310 to 360. Each step will be introduced below.

In step 310, the outdoor temperature value of the unit space is obtained in real time.

In step 320, an initial operating power value of the air conditioner is determined based on the outdoor temperature value and a preset mapping table, where the mapping table includes correspondences between different outdoor temperature values and different operating power values.

In one embodiment, the outdoor temperature value of the unit space can be obtained in real time, and based on the outdoor temperature value, the initial operating power value of the air conditioner corresponding to the outdoor temperature value is determined.

In yet another example, the initial operating power value may be determined according to a preset mapping table. The mapping table includes correspondences between different outdoor temperature values and different operating power values. For example, when the outdoor temperature value is A℃, the corresponding initial operating power value is kW. When the outdoor temperature value is B℃, the corresponding initial operating power value is bkW.

In step 330, the indoor temperature value of the unit space is obtained in real time.

In step 340, the adjusted operating power value is determined based on the indoor temperature value and the initial operating power value.

In another embodiment, the indoor temperature value of the unit space can also be obtained, and the final operating power value (corresponding to the adjusted operating power value) is jointly determined based on the indoor temperature value and the initial operating power value. Through this embodiment, a feedback mechanism can be formed. Taking summer as an example, since the indoor temperature is cooler than the outdoor temperature, it may not be necessary to operate according to the initial operating power value for cooling. In order to save energy and meet user needs, the adjusted operating power value can be determined based on the indoor temperature value and the initial operating power value.

In step 350, when the adjusted operating power value is less than or equal to the maximum operating power value, the adjusted operating power value is used as the target operating power value, and based on the target operating power value, the target operating power gear of the air conditioner is determined. .

In step 360, if the adjusted operating power value is greater than the maximum operating power value, the maximum operating power value is used as the target operating power value, and the target operating power gear of the air conditioner is determined based on the target operating power value.

In another embodiment, when the adjusted operating power value is less than or equal to the maximum operating power value, it means that the operating mode of the air conditioner will not exceed the maximum operation capacity of the air conditioner when it is personalized to match the outside temperature. power value. In this scenario, the maximum operating power value can be used as the target operating power value, and based on the target operating power value, the target operating power level of the air conditioner can be determined. Through this embodiment, the air conditioner can be operated according to an operation mode that is personalized to match the outside temperature without exceeding the maximum operating power value that the air conditioner can carry.

In another embodiment, when the adjusted operating power value is greater than the maximum operating power value, it means that the operating mode of the air conditioner will exceed the maximum operating power value that the air conditioner can carry when it is personalized to match the outside temperature. In this scenario, the adjusted operating power value can be used as the target operating power value, and based on the target operating power value, the target operating power level of the air conditioner can be determined. Through this embodiment, the air conditioner can be operated in an operation mode matching the outside temperature to the maximum extent within the power range that the air conditioner can carry.

Figure 4 is a schematic flow chart of determining the adjusted operating power value based on the indoor temperature value and the initial operating power value provided by the present invention.

The process of determining the adjusted operating power value based on the indoor temperature value and the initial operating power value will be described below with reference to Figure 4.

In an exemplary embodiment of the present invention, it can be seen from FIG. 4 that determining the adjusted operating power value based on the indoor temperature value and the initial operating power value may include steps 410 to 430. Each step will be introduced separately below.

In step 410, the temperature difference between the outdoor temperature value and the indoor temperature value is determined.

In step 420, based on the temperature difference, the operating power adjustment value is determined;

In step 430, an adjusted operating power value is determined based on the initial operating power value and the operating power adjustment value.

In one embodiment, in a scenario where the outdoor temperature value is greater than the indoor temperature value, the temperature difference can be obtained based on the difference between the outdoor temperature value and the indoor temperature value.

In another embodiment, in a scenario where the outdoor temperature value is smaller than the indoor temperature value, the temperature difference can be obtained based on the difference between the indoor temperature value and the outdoor temperature value.

Further, based on the temperature difference, the operating power adjustment value corresponding to the temperature difference can be determined. In an example, the operating power adjustment value may be determined based on a preset mapping table. Among them, the mapping table contains the corresponding relationships between different temperature differences and different operating power adjustment values.

In yet another embodiment, after the operating power adjustment value is determined, the adjusted operating power value may be determined based on the initial operating power value and the operating power adjustment value. In an example, the adjusted operating power value may be determined based on the power difference between the initial operating power value and the operating power adjustment value. Through this embodiment, a feedback mechanism is formed based on the indoor temperature and the outdoor temperature, and the predetermined initial operating power value is adjusted based on the feedback mechanism to obtain a more reasonable adjusted operating power value.

Figure 5 is a second schematic flowchart of a method for controlling the operating mode of an air conditioner based on load provided by the present invention.

Another process of controlling the operating mode of the air conditioner based on load will be described below with reference to FIG. 5 .

In an exemplary embodiment of the present invention, as can be seen in conjunction with Figure 5, a method for controlling the operating mode of an air conditioner based on load may include steps 510 to 540, wherein steps 510 to 530 are the same or similar to steps 110 to 130, and Please refer to the foregoing description for specific implementation methods and beneficial effects. There is no specific limitation in this embodiment. Step 540 will be introduced below.

In step 540, when the signal receiving module receives the characterization signal, the air conditioner is controlled to operate according to the current operating mode.

It can be understood that since the characterization signal is emitted by the signal sending module, if the mains power grid can supply power normally, the signal sending module can transmit the characterization signal, and then the signal receiving module can receive the characterization signal within a preset time period. . Therefore, if the signal receiving module can receive the characterization signal within the preset time period, it means that the mains power grid can supply power normally; if the signal receiving module cannot receive the characterization signal within the preset time period, then it means that the mains power grid can provide normal power supply. The power grid cannot provide normal power supply.

In one embodiment, when the signal receiving module receives the characterization signal within a preset time period, it indicates that the mains power grid is supplying power normally.

Furthermore, when it is detected that the mains power grid can provide normal power supply, it means that the local power grid has sufficient power supply. In this scenario, there is no need to adjust the air conditioner to enter energy-saving mode, but can still control the air conditioner to operate according to the current operating mode. Through this embodiment, it can be ensured that the air conditioner can operate according to the user's settings when the power supply from the power grid is sufficient, thereby improving the user's experience and satisfaction.

In this embodiment, it can be determined whether the mains power grid can provide normal power supply without adding additional costs, and the operating mode of the air conditioner can be automatically controlled at low cost, thereby improving the user's experience and satisfaction during use. Spend.

In yet another exemplary embodiment of the present invention, the characterization signal can be transmitted between the signal transmitting module and the signal receiving module in the following manner:

Load the characterization signal on the current formed by the mains power grid and transmit it on the power line, so that the characterization signal is transmitted from the signal transmitting module to the signal receiving module. Wherein, when the mains power grid supplies normal power, the mains power grid forms a current , and the power line has the ability to transmit signals.

In one embodiment, high-voltage power lines, medium-voltage power lines or low-voltage distribution lines can be used as the information transmission medium instead of WIFI and infrared transmission as the information transmission medium. The preset frequency band signal in the mains power grid can be collected based on the signal sending module, and the preset frequency band signal can be modulated to obtain the modulated signal (which can correspond to the characterization signal). The modulated signal is then loaded onto the power line for transmission. It should be noted that when the mains power grid supplies normal power, power lines have the ability to transmit signals. In other words, when the mains power grid supplies normal power, the signal receiving module can receive the signal sent by the signal sending module.

Further, at the signal receiving module side, when the signal receiving module receives the modulated signal based on the power line, the modulated signal can be demodulated based on the signal receiving module again to obtain the demodulated signal, and determine the demodulated signal Whether the preset frequency band signal is included. If the demodulated signal includes the preset frequency band signal, it means that the mains power grid can supply power normally. Through this embodiment, it can be ensured that the transmission of the characterization signal is only related to the normal power supply of the mains power grid, and will not be affected by whether the WIFI communication signal is good or whether the infrared transmission distance is close enough, thus ensuring accurate signal reception. The signal received by the module represents the reception status and determines whether the mains power grid is supplying power normally.

Figure 6 is a schematic structural diagram of an application scenario of the method for controlling the operating mode of an air conditioner based on load provided by the present invention.

In order to further introduce the method for controlling the operating mode of the air conditioner based on the load provided by the present invention, the following will be described in conjunction with FIG. 6 .

In an exemplary embodiment of the present invention, as can be seen in conjunction with Figure 6, for areas with insufficient power supply, each household can be equipped with an electronically controlled transfer box (corresponding to the power conversion device in Figure 6) placed outdoors, and the electronically controlled transfer box The box can be divided into input and output terminals. Combined with Figure 6, it can be seen that the input end consists of personal power generation, community power generation and city power. The output terminal can be connected to the standing power supply 1 to the standing power supply N. During the application process, the power supply at the input end can come from respective power sources, such as city power, community power generation, personal generators, etc., and the power supply at the output end is connected to the household standing power socket (corresponding to the standing power supply). In addition, the mains power is directly connected to the household mains socket (corresponding to the mains power supply) for non-essential continuous electrical appliances. Among them, the indoor unit 1 of the present invention can be powered by a standing power supply.

It should be noted that N in Figure 6 represents the neutral line and L represents the live line. S2 represents the signal connection line between the indoor unit and the outdoor unit. The indoor unit 1 and the receiving module (corresponding to the signal receiving module of the present invention) can be connected through a signal line to ensure signal transmission between the two.

In an example, the installation form of the transmitting module (corresponding to the signal transmitting module) may be a three-pin plug. The transmitter module can be powered by mains power. The receiving module is installed next to the indoor unit 1 or built inside it. Its power supply comes from the power supply of the indoor unit, and a signal line connects the receiving module and the indoor unit computer board to ensure its signal transmission.

The power supply of the air conditioner can come from the indoor standing power socket to ensure its continuous operation. The transmitting module is plugged into the indoor mains socket, and the receiving module is installed on or next to the indoor unit. The number of receiving modules is not limited to 1 and depends on the number of air conditioners installed in the home. , the number of receiving modules can be equivalent to the number of internal units, and there can be only one transmitting module, or there can be multiple.

During the application process, when the mains power supply is normal, the transmitting module has power to supply it and can transmit signals to the receiving module normally. The power line carrier communication is normal. The receiving module only performs signal analysis and does not issue energy-saving commands. The air conditioner can follow the User settings run.

When there is no mains power, other power sources provide power to the home, and the mains power socket becomes powerless. The transmitting module cannot transmit signals to the receiving module. The program sets the receiving module to issue commands to the computer version of the air conditioner to activate the air conditioner. The air conditioner enters energy-saving mode and controls the energy-saving operation of the air conditioner to ensure that other electrical appliances can operate under limited power capacity.

When shutting down, the specific parameters can be adjusted. The following will introduce how to ensure that the current L during the operation of the air conditioner is always ≤L2-a. Among them, it is detected that the total current L0 of the power supply can flow to the receiving module through the S0 signal connection line; the power current L1 of other electrical appliances can flow to the receiving module through the S1 signal connection line.
