[0047] 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.

[0048] <Thermostat>

[0049] like Figure 1 As shown, an embodiment of the present application provides a thermostat 1, which is electrically connected to an electrical appliance for temperature control (heating or cooling), and its set temperature is used to control the target temperature of the electrical appliance. In this embodiment, the thermostat 1 can be configured to operate in a carbon saving mode. When operating in the carbon saving mode, the set temperature of the thermostat 1 is adjusted according to the green electricity index GEI. The green electricity index GEI is the proportion of green electricity in the power grid to which the thermostat 1 is connected.

[0050] When the proportion of green electricity is high, that is, when the electricity in the power grid mainly comes from renewable energy, such as during the peak hours of clean energy such as wind power and photovoltaic power, the green electricity can be converted into more cold or heat by adjusting the set temperature of the thermostat 1 and stored in the building envelope or other media (such as circulating medium water). For example, when cooling in summer, the set temperature of the thermostat 1 can be appropriately lowered to store cold; and when heating in winter, the set temperature of the thermostat 1 can be appropriately increased to store heat.

[0051] When the green electricity index GEI is low, that is, when the electricity in the power grid is mainly thermal power, such as during the off-peak period of clean energy such as wind power and photovoltaic power, the set temperature of the thermostat 1 can be adjusted to reduce the power consumption during this period. For example, when cooling in summer, the set temperature of the thermostat 1 can be appropriately increased to reduce power consumption; when heating in winter, the set temperature of the thermostat 1 can be appropriately lowered to reduce power consumption.

[0052] The carbon saving mode of thermostat 1 can relatively increase the output of electrical appliances when the green electricity index GEI is high, and store more electricity in the form of cold or heat. When the green electricity index GEI is low, the stored cold or heat can be used, so that the output power of electrical appliances can be appropriately reduced, reducing the use of thermal power. By optimizing the temperature setting method of thermostat 1 in the above way, carbon emissions can be effectively reduced while meeting normal temperature control needs.

[0053] It should be noted that the so-called "carbon saving mode" is a mode in which the set temperature is adjusted according to the green electricity index GEI, which is used to reduce carbon emissions. In some embodiments of the present application, the surface of the thermostat 1 may have a button for triggering the entry into the carbon saving mode, or further have a display unit for separately displaying the carbon saving mode. In other embodiments, the carbon saving mode may also be entered based on other trigger conditions, which is not limited.

[0054] In one or more embodiments of the present application, the setting temperature of the carbon saving mode can be determined locally on the thermostat 1 or in the cloud. In the present embodiment, the setting temperature is determined on the server 3 as an example. Those skilled in the art can understand that the same or similar steps or processes can also be run locally on the thermostat 1 in other embodiments of the present application.

[0055] <System>

[0056] Figure 2 is an architecture diagram of the system provided in this embodiment, which includes a thermostat 1 , a power grid, a server 3 and a power grid server 4 .

[0057] The thermostat 1 may be one or more thermostats 1 in an air conditioning system of an office building, a shopping mall, etc. The air conditioning system is preferably connected to the mains and powered by the power grid, which is equivalent to the thermostat 1 being electrically connected to the power grid.

[0058] refer to Figure 2 The thermostat 1 has a communication module 11 and a positioning module 13. The communication module 11 can be a wireless communication module such as a WIFI module, a Bluetooth module, or a wired communication module, and is used to establish a communication connection with the server 3, thereby uploading the current set temperature T and receiving the updated set temperature T'.

[0059] The positioning module 13 is used to store or determine the installation location information of the thermostat 1. For example, it is a memory that stores the installation location information of the air-conditioning system. The installation location information is entered by the installer when installing the air-conditioning system. Alternatively, the positioning module 13 can also be a GPS module, which detects and determines the installation location information when it is needed.

[0060] In order to monitor the operation status of the power grid, the entity operating the power grid or the related entity provides a power grid server 4. For example, the power grid to which the office building is connected is the power grid in the East China region, and the power grid server 4 is a power grid server 4 that provides the operation information of the power grid in the East China region. The power grid server 4 summarizes various operation status information of the power grid and provides a port for the server 3 to communicate with it. The server 3 provided by the entity operating the air conditioning system can communicate with the power grid server 4 through this port.

[0061] Power grids in different regions may have different green electricity indexes GEI. In this embodiment, the green electricity index GEI of the power grid to which the thermostat 1 is connected can be found based on the installation location information. The installation location information is obtained by the positioning module 13 and uploaded to the server 3 by the communication module 11. The server 3 sends the installation location information to the power grid server 4 and sends a request to find the green electricity index GEI corresponding to the installation location information. After the power grid server 4 returns the green electricity index GEI found to the server 3, the server 3 adjusts the set temperature based on the green electricity index GEI, and then returns the updated set temperature T' to the thermostat 1, and the temperature control module 15 loads the updated set temperature T'.

[0062] <Server>

[0063] Figure 3 It is a schematic diagram of the structure of the server 3 in one or more implementation modes of the present application. Figure 4 It is a flow chart of a method for updating the set temperature that can be executed by the server 3.

[0064] refer to Figure 3 The server 3 includes a processor 33, a memory 35 and a communication module 31. The memory 35 stores processor-readable instructions. The processor 33 executes the processor-readable instructions to enable the server 3 to execute the following Figure 4 During the execution, the communication between the server 3 and other external devices is completed by the communication module 31.

[0065] like Figure 4 As shown, the method for updating the set temperature executed by the server 3 includes the following steps:

[0066] S1: Server 3 receives the current set temperature T of thermostat 1.

[0067] When the thermostat 1 enters the carbon saving mode, the communication module 11 of the thermostat 1 can send the current set temperature T to the server 3 at a specified time, at a specified time interval, or in real time. The following takes the sending time of the current set temperature T as the specified time as an example for explanation. For example, the thermostat 1 entering the carbon saving mode can send the current set temperature T at every hour of the day, such as 14:00, 15:00, etc.

[0068] The installation location information may be sent to the server 3 in step S1 , or may be sent to the server 3 before step S1 , and stored by the server 3 in a manner associated with the MAC address or other characteristic values ​​of the thermostat 1 .

[0069] After step S1, step S2 is performed: determining a green electricity index GEI.

[0070] refer to Figure 2 The green electricity index GEI can be obtained through the power grid server 4. The power grid server 4 is connected to the server 3 for communication. The server 3 sends a green electricity index request instruction (including the installation location information of the thermostat 1) to the power grid server 4. After receiving the green electricity index request instruction, the power grid server 4 sends the green electricity index GEI corresponding to the installation location information to the server 3, thereby determining the green electricity index GEI.

[0071] In this embodiment, the green electricity index GEI received at different times is stored or cached by the server 3 in association with the MAC address of the thermostat 1 and recorded as a historical record of the green electricity index GEI. The green electricity index GEI determined in step S2 can be the green electricity index GEI of the power grid at the current moment, or it can be the green electricity index GEI' predicted for a period of time in the future based on historical records. Specifically, a model can be trained based on the historical records of the green electricity index, and the predicted value of the green electricity index for a period of time in the future can be determined based on the model. The training and application of the model can be completed at the power grid server 4 or at the server 3.

[0072] After step S2, step S3 is executed: adjusting the set temperature of thermostat 1 according to the green electricity index GEI of the power grid to which thermostat 1 is connected, thereby obtaining an updated set temperature T', wherein the green electricity index GEI is the proportion of green electricity in the power grid to which thermostat 1 is connected.

[0073] Continue to refer Figure 4 , step S3 further includes the following process:

[0074] First, determine whether the air conditioning system connected to or controlled by the thermostat 1 is cooling or heating. This information can be uploaded by the thermostat 1 to the server 3, or determined by the server 3 based on the comparison between the current ambient temperature and the set temperature. For example, if the set temperature is lower than the current ambient temperature, it is determined that the air conditioning system is cooling; if the set temperature is higher than the current ambient temperature, it is determined that the air conditioning system is heating. In addition, it can also be determined in combination with the current season information, installation location information, etc.

[0075] Next, the absolute value |ΔGEI| of the change amount ΔGEI of the green power index GEI is compared with the threshold value TH.

[0076] In this embodiment, in order to improve the stability of the set temperature and enhance the user's body feeling in the carbon saving mode, a threshold TH is set. When the absolute value of the change in the green electricity index GEI is less than the threshold TH, the set temperature remains unchanged; when the absolute value of the change in the green electricity index GEI is greater than the threshold TH, the change direction of the green electricity index GEI is determined. For example, the threshold TH can be 10%. If ΔGEI is greater than 10%, the set temperature T is increased or decreased by ΔT (such as 2°C) according to the change direction, otherwise the set temperature remains unchanged.

[0077] It should be noted that the change ΔGEI of the green electricity index GEI can be the difference between the current green electricity index GEI and the most recently recorded green electricity index GEI in the historical records, or the difference between the predicted value of the green electricity index GEI in a certain period of time in the future and the current green electricity index GEI, or other changes that can reflect the changing trend of the green electricity index GEI.

[0078] By setting the change ΔGEI of the green electricity index GEI as the difference between the predicted value of the green electricity index GEI in the future and the current green electricity index GEI, a certain time lag in the release of the green electricity index GEI can be allowed, and the set temperature can still be adjusted in time to reduce carbon emissions.

[0079] When the air conditioning system controlled by thermostat 1 is in cooling operation, if the green electricity index GEI increases by more than the threshold, the set temperature is lowered; if the green electricity index GEI decreases by more than the threshold, the set temperature is raised. When the air conditioning system controlled by thermostat 1 is in heating operation, if the green electricity index GEI increases by more than the threshold, the set temperature is raised; if the green electricity index GEI decreases by more than the threshold, the set temperature is lowered.

[0080] Among them, "increase the set temperature" and "lower the set temperature" are to increase or decrease based on the current set temperature T. The increase or decrease range can be a fixed value, such as 1-3℉, or can be adjusted according to the change in the green electricity index ΔGEI.

[0081] During cooling, if the green electricity index GEI increases by more than the threshold TH, lowering the set temperature can convert more green electricity into cold storage. The stored cold can be used when the green electricity index GEI is lower to meet the cooling demand when the green electricity index GEI is lower, increase the use of green electricity and reduce the use of thermal power, thereby reducing carbon emissions.

[0082] Similarly, during heating, if the green electricity index GEI increases by more than the threshold TH, increasing the set temperature can convert more green electricity into heat for storage. The stored heat can be used when the green electricity index GEI is lower to meet the heating demand when the green electricity index GEI is lower, increase the use of green electricity and reduce the use of thermal power, thereby reducing carbon emissions.

[0083] Continue to refer Figure 4 After step S3, step S4 is executed to send the updated set temperature T' to the thermostat 1, which is loaded and executed by the temperature control module 15 of the thermostat 1.

[0084] Through the above method, the server can centrally process and coordinate the calculation of the set temperature, flexibly adjust the set temperature of the thermostat 1 according to the green electricity index GEI, and reduce carbon emissions.

[0085] In some embodiments of the present application, Figure 4 The method flow for updating the set temperature shown can also be run in the thermostat 1 or other electrical appliances for temperature control to adjust the set temperature of the thermostat 1 or other electrical appliances for temperature control to reduce carbon emissions.

[0086] In other embodiments of the present application, the set temperature may also be adjusted according to the comparison result between the green power index GEI and the preset value. For example, when the green power index GEI is greater than the first preset value and in the cooling mode, the set temperature is lowered; and when the green power index GEI is less than the first preset value, the set temperature is increased or maintained unchanged.

[0087] The electrical appliance for temperature control used by the thermostat 1 in the implementation manner of the present application is not limited to the air-conditioning system listed in the above implementation manner, but can also be other refrigeration and / or heating appliances, and is not limited to household or industrial refrigeration and / or heating appliances, such as refrigerators, refrigerators, freezers and other refrigeration appliances; or the appliance is an electric heating shower equipment and other industrial electric heating equipment.

The memory 35 may be an independent external memory, including but not limited to a random access memory (RAM), a read-only memory (ROM), a programmable read-only memory (PROM), an erasable read-only memory (EPROM), and an electrically erasable read-only memory (EEPROM).
