Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, and in particular to a method and circuit for metering the electric auxiliary heating power of an air conditioner. Background Technology

[0002] Energy conservation and environmental protection have become basic requirements for people's home appliances. In order to enable people to accurately know the electricity consumption of air conditioners, more and more air conditioners are equipped with electricity metering functions. However, air conditioner electricity metering is mostly based on static metering, that is, the power of the air conditioner is set at the factory, and the electricity metering module only calculates the electricity consumption based on the usage time of the air conditioner. This method will bring great limitations to the electricity metering device.

[0003] For example, when the ambient temperature is too low and the air conditioner compressor's heating efficiency is low, the air conditioner often uses an electric auxiliary heating device to assist in heating in order to achieve the heating target. Because users have different usage environments for air conditioners, their needs for electric auxiliary heating also vary. Therefore, some air conditioners allow users to freely select electric auxiliary heating, thereby improving the versatility of the air conditioner and meeting the diverse needs of users for electric auxiliary heating.

[0004] However, electric auxiliary heating may fail during use, resulting in inaccurate electricity metering of the air conditioner. Therefore, determining the selection and failure status of electric auxiliary heating to accurately measure the electricity consumption of the air conditioner becomes a problem that needs to be solved.

[0021] Based on the newly determined target electric auxiliary heating device, continue with the electricity metering step.

[0022] In one possible implementation, the electricity consumed by the target electric auxiliary heating device from the start-up time to the current time is recorded in real time, including:

[0023] Obtain the power of the target electric auxiliary heating device and the pre-calibrated power consumption before stabilization, wherein the power consumption before stabilization is the amount of electricity consumed by the target electric auxiliary heating device from the start-up time to the power stabilization time;

[0024] Determine the time elapsed from the moment the target electric auxiliary heating device reaches power stability to the current moment;

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0063] To address the technical problem that existing air conditioning electric auxiliary heating devices cannot accurately measure electricity consumption, this application provides a method for measuring the electricity consumption of air conditioning electric auxiliary heating devices. This method can automatically detect the effectiveness of the electric auxiliary heating device and record the electricity consumed by the device when it is effective, thereby improving the accuracy of air conditioning electricity statistics.

[0064] Figure 1This is a flowchart illustrating a method for metering the electricity consumption of an air conditioner's auxiliary electric heating system, provided in an embodiment of this application. This method can be applied to an air conditioner and executed by the auxiliary electric heating controller or the main controller. Optionally, this method can also be executed by other electronic devices connected to the air conditioner, such as smartphones, laptops, or servers. These electronic devices can obtain data such as the air outlet temperature from the air conditioner, execute this method, obtain a processing result (e.g., recorded electricity consumption), and can feed the processing result back to the air conditioner. Furthermore, the executing entity of this method can be hardware or software. When the executing entity is hardware, it can be one or more of the aforementioned electronic devices. For example, a single electronic device can execute this method, or multiple electronic devices can cooperate with each other to execute this method. When the executing entity is software, this method can be implemented as multiple software programs or software modules, or as a single software program or software module. No specific limitations are made here.

[0065] like Figure 1 As shown, the method specifically includes:

[0066] Step 101: In response to activating the electric auxiliary heating function on the air conditioner, determine the target electric auxiliary heating device to be activated from at least one preset electric auxiliary heating device on the air conditioner, and perform the following power metering steps based on the target electric auxiliary heating device.

[0067] In some embodiments, the electric auxiliary heating function can be automatically triggered by the air conditioner based on its current operating status. For example, when the air conditioner's main controller determines that the compressor's heating capacity is insufficient to meet the user's or system's heating requirements (e.g., the temperature rise rate is too low), the electric auxiliary heating function is automatically activated. The electric auxiliary heating function can also be manually activated by the user, for example, by the user activating the electric auxiliary heating function via a remote control.

[0068] The aforementioned at least one electric auxiliary heating device is used to provide auxiliary heating for the air conditioner when the external ambient temperature is too low. This function can be achieved through heating resistance wires or the like. The target electric auxiliary heating device is one of at least one electric auxiliary heating device. If there are multiple electric auxiliary heating devices, one can be selected (e.g., selected in sequence) as the electric auxiliary heating device.

[0069] Steps 102-105 are included in the electricity metering step.

[0070] Step 102: Start the target electric auxiliary heating device.

[0071] In some embodiments, the electronic device performing this method can connect the target electric auxiliary heating device to the power supply by sending a control command to the switch connected to the target electric auxiliary heating device, thereby starting to heat.

[0072] Step 103: Obtain the current temperature of the air outlet of the air conditioner from the temperature sensor installed at the air outlet of the air conditioner.

[0073] In some embodiments, a temperature sensor may be installed at the air outlet of the air conditioner. This temperature sensor is used to collect the temperature of the air outlet in real time and transmit the temperature signal to the electronic device executing this method. The type of temperature sensor can be various, such as a thermistor, an infrared thermometer, etc.

[0074] Step 104: Based on the temperature changes, determine whether the target electric auxiliary heating device is effective.

[0075] In some embodiments, the effectiveness of the target electric auxiliary heating device can be determined by detecting whether the outlet temperature rises. For example, if the temperature rise exceeds a set threshold, the target electric auxiliary heating device is determined to be effective, that is, the target electric auxiliary heating device can generate heat normally.

[0076] Step 105: If the target electric auxiliary heating device is effective, record in real time the amount of electricity consumed by the target electric auxiliary heating device from the start time to the current time.

[0077] In some embodiments, the electronic device performing this method may record the start-up time of the target electric auxiliary heating device (e.g., record the timestamp when the start-up command is sent), and then begin to calculate the power consumption of the target electric auxiliary heating device. For example, the current or voltage of the target electric auxiliary heating device can be detected in real time by a current detection device or a voltage detection device, and the power consumption can be calculated based on the power consumption calculation formula.

[0078] The air conditioner auxiliary heating power metering method provided in this application involves identifying a target auxiliary heating device from at least one auxiliary heating device on the air conditioner when the auxiliary heating function is activated. The target auxiliary heating device is then activated, and the current temperature of the air conditioner's air outlet is acquired. Based on the temperature change, the effectiveness of the target auxiliary heating device is determined. If the target auxiliary heating device is effective, the power consumption from activation to the current time is recorded in real time. This application embodiment automatically detects the effectiveness of the air conditioner's auxiliary heating device, records the power consumption of the device when its effectiveness is ensured, and accurately records the power consumption of the auxiliary heating device on the air conditioner. It also detects the effectiveness of the auxiliary heating device, facilitating user maintenance of the auxiliary heating device.

[0079] In some alternative implementations, after step 104, the method further includes:

[0080] Generate and output a prompt message indicating whether the target electric auxiliary heating device is effective.

[0081] The generated prompts can take various forms, such as digital signals, audio signals, text information, and image information. The prompts can be output in various ways; for example, they can be light control signals that control the LEDs on the air conditioner to emit light of a corresponding color to indicate whether the target electric auxiliary heating device is effective. Another example is that if the target electric auxiliary heating device is ineffective, the number of the ineffective device can be displayed on the air conditioner's screen.

[0082] This embodiment outputs a prompt message indicating whether the target electric auxiliary heating device is effective, which can promptly show the user the effectiveness of the electric auxiliary heating device and facilitate the user's maintenance of the electric auxiliary heating device.

[0083] In some alternative implementations, such as Figure 2 As shown, step 104 includes:

[0084] Step 1041: If the temperature rise at the air outlet of the air conditioner is greater than or equal to a preset threshold value within a preset time period, and / or the temperature rise rate at the air outlet of the air conditioner is greater than or equal to a preset rate threshold value, the target electric auxiliary heating device is determined to be effective.

[0085] The preset duration, preset amplitude threshold, and preset rate threshold can be set according to actual needs. For example, the preset duration is 20s, the preset amplitude threshold is 2℃, and the preset rate threshold is 0.1℃ / s.

[0086] Step 1042: If the temperature rise at the air outlet of the air conditioner is less than the preset threshold value within the preset time period, or the temperature rise rate at the air outlet of the air conditioner is less than the preset rate threshold value, the target electric auxiliary heating device is determined to be invalid.

[0087] For example, if the air outlet temperature does not rise within a preset time period, or the rise is less than a preset threshold, it can be determined that the target electric auxiliary heating device is not working properly and is therefore invalid.

[0088] This embodiment, by setting temperature rise range and temperature rise rate conditions, can accurately determine whether the target electric auxiliary heating device is effective based on the changes in the air outlet temperature of the air conditioner, thereby improving the accuracy of metering the power consumption of the air conditioner.

[0089] In some alternative implementations, such as Figure 3 As shown, the number of at least one electric auxiliary heating device is at least two.

[0090] Following step 105, the method further includes:

[0091] Step 106: In response to the fact that the time between the current time and the start time of the target electric auxiliary heating device is greater than or equal to a preset time, the target electric auxiliary heating device is re-determined from the electric auxiliary heating devices on the air conditioner that have not performed the power metering step.

[0092] The preset duration can be set according to requirements. Typically, the preset duration needs to be longer than the time required for the electric auxiliary heating device to reach stable heating, and this can be determined through actual measurement. A new target electric auxiliary heating device can be selected from those that have never undergone the electricity metering step, either sequentially or randomly.

[0093] Step 107: Based on the newly determined target electric auxiliary heating device, continue with the electricity metering step.

[0094] That is, based on the newly determined target electric auxiliary heating device, continue from step 102 above and repeat the subsequent steps until all electric auxiliary heating devices have performed the electricity metering step.

[0095] In this embodiment, when there are multiple electric auxiliary heating devices, the power metering step is performed sequentially for each electric auxiliary heating device. After each power metering step is completed, a period of time is waited to allow the first electric auxiliary heating device to stabilize before starting the next one. This allows for accurate and stable effectiveness detection and power metering of each electric auxiliary heating device.

[0096] In some alternative implementations, such as Figure 4 As shown, the number of at least one electric auxiliary heating device is at least two.

[0097] Following step 104, the method further includes:

[0098] Step 108: If the target electric auxiliary heating device is invalid, control the target electric auxiliary heating device to stop operating, and re-determine the target electric auxiliary heating device from among the electric auxiliary heating devices on the air conditioner that have not performed the electricity metering step.

[0099] Specifically, if the target electric auxiliary heating device is determined to be invalid, the switch connected to the target electric auxiliary heating device can be disconnected to cut off the power supply to the target electric auxiliary heating device and thus stop its operation. Then, a new target electric auxiliary heating device can be identified.

[0100] Step 109: Based on the newly determined target electric auxiliary heating device, continue with the electricity metering step.

[0101] This embodiment ensures the safe operation of the air conditioner by controlling the operation of a single electric auxiliary heating device to stop if the device is ineffective when there are multiple electric auxiliary heating devices. Then, the power metering step is performed on the next electric auxiliary heating device to determine its effectiveness. This allows for accurate, safe, and stable effectiveness detection and power metering for each electric auxiliary heating device.

[0102] In some alternative implementations, such as Figure 5 As shown, step 105 includes:

[0103] Step 1051: Obtain the power of the target electric auxiliary heating device and the pre-calibrated power consumption before stabilization.

[0104] The power consumption before stabilization refers to the power consumed by the target electric auxiliary heating device from startup to power stabilization. The power of the target electric auxiliary heating device is its rated power, that is, the power of the target electric auxiliary heating device when it is heating steadily.

[0105] The power consumption before stabilization can be obtained by measuring and statistically analyzing the power consumption of multiple electric auxiliary heating devices in advance.

[0106] Step 1052: Determine the elapsed time from the moment the target electric auxiliary heating device reaches power stability to the current moment.

[0107] Step 1053: Calculate the product of power and duration, and add it to the power consumption before stabilization to obtain the power consumption of the target electric auxiliary heating device from the start-up time to the current time.

[0108] Specifically, let the power be P, the duration be t, and the power consumption before stabilization be W0. Then the power consumption W of the target electric auxiliary heating device from the start-up time to the current time is: W = W0 + P * t.

[0109] This embodiment calculates the power consumption of the target electric auxiliary heating device by pre-setting the power and power consumption before stabilization, eliminating the need for a dedicated power metering device, thus reducing the hardware cost of the air conditioner and improving the efficiency of power metering.

[0110] Figure 6 This is a schematic diagram of the structure of an air conditioner electric auxiliary heating power metering circuit 600 provided in an embodiment of this application. Specifically, it includes: an electric auxiliary heating control module 601, at least one electric auxiliary heating device 602, at least one switching module 603, and a temperature sensor 604.

[0111] Each of the at least one electric auxiliary heating device corresponds to one of the at least one switching modules, and one end of each electric auxiliary heating device is connected to a first power supply terminal, and the other end is connected to the first contact of the corresponding switching module.

[0112] like Figure 6 As shown, the circuit includes three electric auxiliary heating devices, labeled R1, R2, and R3, and corresponding to switch modules K1, K2, and K3, respectively. For R1, one end is connected to the first power supply terminal (AC_N, i.e., the neutral line of the AC circuit), and the other end is connected to the first contact of the corresponding switch module K1.

[0113] The second contact of each of at least one switch module is connected to the second power supply terminal.

[0114] like Figure 6 As shown, the second contacts of switch modules K1, K2, and K3 are all connected to the second power supply terminal (AC_L, i.e., the live wire of the AC circuit).

[0115] The control terminal of each of at least one switching module is connected to the electric auxiliary heating control module.

[0116] Switching modules can employ various types of controlled switching devices, such as relays, thyristors, and transistors. For example... Figure 6 As shown, the electric auxiliary heating control module may include at least one output port, each output port being connected to the control terminal of a corresponding switching module. The electric auxiliary heating control module can send control signals to the corresponding switching module through the output port to control the switching module to close or open.

[0117] The temperature sensor is connected to the electric auxiliary heating control module to collect the temperature of the air outlet of the air conditioner.

[0118] This temperature sensor can be installed at the air outlet of the air conditioner. Various types of temperature sensors can be used, such as thermistors and infrared thermometers. Figure 6 As shown, the temperature sensor is a thermistor R4, one end of which is connected to the input port of the electric auxiliary heating control module, and the other end is connected to a +3.3V level. R4 exhibits different resistance values ​​at different temperatures, thereby generating different voltage values ​​at the input port of the electric auxiliary heating control module, which in turn represent the temperature.

[0119] An auxiliary electric heating control module is used in the air conditioner auxiliary electric heating power metering method described in any of the above embodiments. Specifically, in response to activating the auxiliary electric heating function on the air conditioner, the auxiliary electric heating control module determines a target auxiliary electric heating device to be activated from at least one auxiliary electric heating device, and based on the target auxiliary electric heating device, performs the following power metering steps:

[0120] Control the start of the target electric auxiliary heating device; obtain the current temperature of the air conditioner outlet from the temperature sensor; determine whether the target electric auxiliary heating device is effective based on the temperature change; if effective, record the power consumption of the target electric auxiliary heating device from the start time to the current time in real time.

[0121] The electric auxiliary heating control module is an electronic device with logic processing capabilities. It can be a standalone control chip, such as an MCU or DSP, or a control circuit composed of various electronic components.

[0122] like Figure 7 As shown, it illustrates the target Figure 6The circuit shown is a flowchart illustrating the power metering process for three auxiliary electric heating devices via an auxiliary electric heating control module. Specifically, after activating the auxiliary electric heating function, K1 is first turned on, allowing current to flow into R1, causing R1 to heat up. If the temperature sensor detects an increase in the air conditioner outlet temperature, the power consumption of R1 is measured. Then, after a period of time, R1 stabilizes at its heating state, at which point K2 is turned on. If the temperature sensor detects an increase in the air conditioner outlet temperature, the power consumption of R2 is measured. Similarly, the power consumption of R3 continues to be measured. Finally, the validity information of R1, R2, and R3 is output, allowing the user to know the operating status of each auxiliary electric heating device.

[0123] The air conditioner auxiliary heating power metering circuit provided in this application embodiment, by setting a temperature sensor at the air conditioner outlet and setting a corresponding switch module for each auxiliary heating device, and having the auxiliary heating control module execute the above-mentioned air conditioner auxiliary heating power metering method, realizes automatic effectiveness detection of the air conditioner's auxiliary heating device. When the auxiliary heating device is ensured to be effective, the power consumed by the auxiliary heating device is recorded. Thus, the power consumption of the auxiliary heating device on the air conditioner is accurately recorded, and the effectiveness of the auxiliary heating device can be detected, which is convenient for users to maintain the auxiliary heating device.

[0124] In some alternative implementations, such as Figure 8 As shown, each of the at least one switch module includes a relay, the first contact of which is connected to a corresponding electric auxiliary heating device, and the second contact of which is connected to a second power supply terminal.

[0125] The two ends of the relay's electromagnetic coil are connected to the electric auxiliary heating control module and the preset level terminal, respectively.

[0126] like Figure 8 As shown, for the switch module K1, its first contact is connected to the electric auxiliary heating device R1, and its second contact is connected to the AC_L terminal. One end of the electromagnetic coil included in K1 is connected to an output port of the electric auxiliary heating control module, and the other end is connected to a +12V level terminal. When the electric auxiliary heating control module needs to control the electric auxiliary heating device K1 to start, it can output a low level to the electromagnetic coil of K1 through the output port. The electromagnetic coil generates magnetism, driving the first and second contacts of K1 to conduct. When the electric auxiliary heating control module needs to control the electric auxiliary heating device K1 to stop, it can output a high level to the electromagnetic coil of K1.
