[0002] Many electrical appliances, such as air conditioners, heaters, and electric heaters, have a heating function and need to maintain the air outlet temperature within a specific range. However, changes in ambient temperature will affect the operation of these appliances, causing the air outlet temperature to deviate from the target value.

[0003] To solve the above problems, it is usually necessary to use at least two temperature sensing packages and set two AD detection ports to simultaneously detect the ambient temperature and the air outlet temperature so as to adjust the air outlet temperature in real time. However, this design increases the complexity and cost of the equipment and also increases the failure rate. Summary of the invention

[0015] At least one embodiment of the present application further provides a computer-readable storage medium storing a computer program, wherein the computer program implements the above-mentioned temperature adjustment method when executed by a processor.

[0016] The temperature adjustment method, system, device and storage medium provided by the embodiments of the present application utilize a temperature detection device disposed at the air outlet, combined with a first mapping relationship between a preset ambient temperature, a heating element power and an air outlet temperature, to infer the current ambient temperature estimate, thereby eliminating the need for an additional ambient temperature monitoring device. After determining the ambient temperature estimate, the target value of the air outlet temperature corresponding to the ambient temperature estimate when the ambient temperature is adjusted to the target temperature can be determined based on a second mapping relationship between the preset ambient temperature, the air outlet temperature and the target temperature. This achieves the goal of adjusting the air outlet temperature by using only one temperature detection device, thereby reducing the complexity, cost and failure rate of the equipment.

[0017] In one embodiment, after adjusting the heating element power of the heating device so that the air outlet temperature reaches the second temperature target value, the method further includes:

[0020] Based on a second mapping relationship between the air outlet temperature, the ambient temperature, and the target temperature, determining a new second temperature target value of the air outlet temperature when the temperature of the target environment reaches the target temperature from the new ambient temperature estimate value;

[0021] The power of the heating element of the heating device is adjusted so that the air outlet temperature reaches the new second temperature target value.

[0022] As the air outlet temperature is continuously adjusted, the ambient temperature is also constantly changing. In order to stabilize the ambient temperature at the target temperature, in this embodiment, the current air outlet temperature is monitored in real time and the air outlet temperature is continuously corrected so that the indoor temperature can always be maintained at the target temperature.

[0023] In one embodiment, the outlet temperature monitoring value is kept constant at a preset first temperature target value, including:

[0024] Within a preset determination time, the air outlet temperature monitoring value is always within a first preset temperature range to which the first temperature target value belongs.

[0025] In this embodiment, by setting a judgment time and a temperature range instead of a single temperature point, it is possible to more stably judge whether the outlet temperature has reached the target state, which helps to reduce misjudgments caused by temperature fluctuations or measurement errors and enhance the robustness of the system.

[0027] According to the difference between the air outlet temperature monitoring value and the second temperature target value, the PID algorithm is used to dynamically adjust the power of the heating element until the air outlet temperature reaches the second temperature target value.

[0028] In this embodiment, the PID algorithm can achieve more precise control of the air outlet temperature, help reduce temperature fluctuations, and maintain the air outlet temperature more stably near the target value, while adjusting the speed more efficiently.

[0032] The power of the heating element is adjusted according to the preset range of the power of the heating element, the maximum output value of the PID controller and the comprehensive output value.

[0033] In this embodiment, when adjusting the power of the heating element, the preset range of the heating element power and the maximum output value of the PID controller are taken into consideration, which helps to prevent damage to the heating device or exceeding the safety range of the system due to excessive power adjustment.

[0034] In one embodiment, adjusting the power of the heating element according to the preset range of the power of the heating element, the maximum output value of the PID controller and the comprehensive output value includes:

[0035] Adjust the heating element power according to the following calculation formula:

[0036]

[0037] Where D(t) is the adjusted heating element power, D min and D max are the minimum and maximum values ​​of the heating element power, u max is the maximum output value of the PID controller, and u(t) is the comprehensive output value.

[0038] In this embodiment, the interpolation method can be used to more quickly and accurately calculate the target value of the heating body power to be adjusted, thereby improving the processing efficiency of the system.

[0039] In one embodiment, when the outlet temperature monitoring value is constant at a preset first temperature target value, obtaining the first heating element power of the heating device includes:

[0040] According to the difference between the air outlet temperature monitoring value and the first temperature target value, the PID algorithm is used to dynamically adjust the heating element power of the heating device until the air outlet temperature monitoring value is constant at the preset first temperature target value, thereby obtaining the first heating element power of the heating device.

[0041] In this embodiment, when the air outlet temperature gradually increases to the first temperature target value, dynamic adjustment using the PID algorithm helps the system reach the first temperature target value more quickly and smoothly, allowing the system to start regulating the air outlet temperature more quickly.

[0042] In one embodiment, it further includes:

[0043] Based on the user's heating habits, the first temperature target value is updated.

[0050] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined and referenced with each other under the premise of no contradiction.

[0051] In order to solve the above-mentioned technical problem that at least two temperature sensing packages are usually required and two AD detection ports are set, which increases the complexity, cost and failure rate of the equipment, the present invention proposes a temperature adjustment method. The implementation details of the temperature adjustment method of this embodiment are specifically described below. The following content is only the implementation details provided for the convenience of understanding and is not necessary for the implementation of this solution.

[0052] Embodiment 1:

[0053] The temperature adjustment method of this embodiment can be applied to electronic devices with communication, computing and data storage capabilities. The specific process can be as follows: Figure 1 As shown, including:

[0054] Step 110, monitor the air outlet temperature of the heating device in the target environment to obtain an air outlet temperature monitoring value.

[0055] In this embodiment, the target environment is the spatial area to be heated by the heating device. For example, a room or space, such as a data center, a computer room, a laboratory, etc.; or the internal environment of a device or system, such as a car engine compartment, the interior of an air conditioning or refrigeration system, etc.; or a specific area in an industrial or manufacturing process, such as a workstation on a production line, the surrounding environment of a chemical reactor, etc. A heating device refers to a device or system that can generate heat and needs to discharge the heat through an air outlet. A heating device usually has one or more air outlets for dissipating the heat generated inside to the external environment. For example, a heating device is a central air conditioner, a household air conditioner, or an electric heater.

[0056] The air outlet temperature refers to the temperature of the air or fluid discharged from the air outlet of the heating device. During actual measurement, a temperature sensor can be arranged at the air outlet to obtain the air outlet temperature monitoring value in real time.

[0057] Step 120: When the outlet temperature monitoring value is constant at a preset first temperature target value, the power of the first heating element of the heating device is obtained.

[0058] In this embodiment, when the user starts the heating mode, the heating element of the heating device generates heat to heat the airflow inside the system, so that the outlet temperature gradually increases. The first temperature target value is a temperature value set in advance, which serves as a reference standard for monitoring the outlet temperature. When the actual monitored outlet temperature (i.e., the outlet temperature monitoring value) matches or is close to the first temperature target value, it is considered that the heating device has reached a certain preset specific operating state. At this time, it is necessary to obtain the power of the first heating element of the heating device to further adjust the outlet temperature.

[0059] In one embodiment, the air outlet temperature corresponding to the most likely usage scenario is selected as the first temperature target value. In this embodiment, the most likely usage scenario is the air outlet temperature that the heating device should be set to in the heating scheme selected by most users. For example, most people choose to heat the temperature to 25 degrees Celsius, and the corresponding air outlet temperature or the first temperature target value is set to 60°C.

[0060] In one embodiment, the method further includes: updating the first temperature target value based on the user's heating habits.

[0061] In this embodiment, the first temperature target value is usually initially set to the outlet temperature corresponding to the usage scenario with the highest probability of user selection. After statistics on the user's heating habits, the first temperature target value is updated accordingly, so that the heating process can reach the user's set state faster. For example, the initially set first temperature target value is 55°C. After a period of statistics, it is found that when the temperature is below 10°C, the user is accustomed to setting the heating mode to 30°C. The first temperature target value is set to 60°C, so that the room temperature can reach the target temperature set by the user faster, and the heating device is more user-friendly to meet the needs of users.

[0062] In one embodiment, the air outlet temperature monitoring value is constant at a preset first temperature target value, including: within a preset determination time, the air outlet temperature monitoring value is always within a first preset temperature range to which the first temperature target value belongs.

[0063] In this embodiment, by setting a judgment time and a temperature range instead of a single temperature point, it is possible to more stably judge whether the outlet temperature has reached the target state, which helps to reduce misjudgments caused by temperature fluctuations or measurement errors and enhance the robustness of the system.

[0064] For example, the judgment time is set to 5 seconds, the first temperature target value is 60°C, the first preset temperature range is [59°C, 61°C], and the system obtains the outlet temperature every 1 second. If the outlet temperature monitoring values ​​obtained within 5 seconds are all within the first preset temperature range, it means that the outlet temperature monitoring values ​​are constant at the preset first temperature target value.

[0065] Step 130, based on a first mapping relationship between a preset ambient temperature, a heating element power, and an air outlet temperature, determine an estimated ambient temperature value corresponding to the first heating element power when the air outlet temperature monitoring value is constant at the first temperature target value.

[0066] It can be understood that when the power of the heating element changes, the temperature of the air outlet also changes, which in turn causes the ambient temperature to gradually change. Therefore, the change in the power of the heating element affects the ambient temperature by affecting the temperature of the air outlet, forming a continuous mapping chain, that is, there is a first mapping relationship between the ambient temperature and the power of the heating element and the temperature of the air outlet. The first mapping relationship is obtained in advance through a large number of experiments. For example, the first mapping relationship is established by controlling variables and real-time monitoring. The specific steps are as follows:

[0067] 1) Control variables: set different ambient temperatures Tc and fix the target temperature Tp.

[0068] 2) Real-time monitoring: record the air outlet temperature and heating element power required to reach the target temperature under different ambient temperatures.

[0069] 3) Data collation: The experimental data are collated into Table 1 below to facilitate quick search and use by the controller in practical applications.

[0070] Table 1 Comparison table of ambient temperature, heating element power and air outlet temperature

[0071]

[0072] Table 1 above lists some parameters. In actual statistics, the air outlet temperature, heating element power and ambient temperature have higher statistical accuracy. For example, the air outlet temperature is 60°C, 60.5°C, 61°C..., and the ambient temperature is 0°C, 0.5°C, 1°C...

[0073] The first mapping relationship or mapping table is stored in a database. When the outlet temperature monitoring value is constant at the first temperature target value, by obtaining the heating element power at that moment, the ambient temperature estimation value corresponding to the first heating element power when the outlet temperature monitoring value is constant at the first temperature target value can be obtained. This method can obtain the current ambient temperature without installing an additional device for detecting the ambient temperature.

[0074] In existing heating devices, such as air conditioning systems, voltage sensors and current sensors are usually installed to monitor the voltage and current at both ends of the heating element in real time. The power of the heating element can be calculated based on the voltage and current. A power meter can also be used to directly connect to the circuit of the heating element to measure its power.

[0075] Step 140, based on a second mapping relationship between the preset air outlet temperature, the ambient temperature, and the target temperature, determine a second temperature target value of the air outlet temperature when the temperature of the target environment reaches the target temperature from the ambient temperature estimate value.

[0076] It can be understood that the air outlet temperature is a direct means for the heating device to adjust the indoor temperature. When the target ambient temperature is higher than the current ambient temperature, the heating device needs to heat the indoor air by increasing the air outlet temperature (in heating mode) so that it gradually approaches and reaches the target temperature. On the contrary, when the target ambient temperature is lower than the current ambient temperature, the heating device needs to lower the air outlet temperature (in cooling mode) to cool the indoor air. Therefore, there is a direct correspondence between the air outlet temperature and the estimated ambient temperature and the target ambient temperature, that is, the second mapping relationship.

[0077] The method for determining the second mapping relationship is similar to the method in the above step 130, and the following Table 2 is obtained through experimental statistics:

[0078] Table 2 Comparison table of ambient temperature, air outlet temperature and target temperature

[0079]

[0080] The target temperature is set by the user. After obtaining the current ambient temperature (i.e., the estimated ambient temperature), the value that the corresponding air outlet temperature should be set to when adjusting the temperature of the target environment from the estimated ambient temperature to the target temperature can be obtained, i.e., the second temperature target value.

[0081] Step 150: Adjust the power of the heating element of the heating device so that the air outlet temperature reaches the second temperature target value.

[0082] In this embodiment, after the second temperature target value is determined, the air outlet temperature can be gradually changed to the second temperature target value by increasing or decreasing the power of the heating element.

[0083] For example, the user sets the target temperature to 30℃ and monitors the outlet temperature in real time. When the outlet temperature monitoring value stabilizes at 60℃, the current heating element power is 70%. By querying Table 1, the current ambient temperature estimate is 5℃. Then, by querying Table 2, when the ambient temperature is 5℃ and the target temperature is 30℃, the outlet temperature should be set at 65℃. It can be seen that the outlet temperature should be increased from 60℃ to 65℃, and the heating element power should be adjusted accordingly to increase the outlet temperature to 65℃.

[0084] In summary, the temperature adjustment method provided in this embodiment only needs to utilize the temperature detection device provided at the air outlet, combined with the first mapping relationship between the preset ambient temperature, the power of the heating element, and the air outlet temperature, to infer the current ambient temperature estimate, thereby eliminating the need for an additional ambient temperature monitoring device. After determining the ambient temperature estimate, the target value of the air outlet temperature corresponding to the ambient temperature estimate when the ambient temperature is adjusted to the target temperature can be determined based on the second mapping relationship between the preset ambient temperature, the air outlet temperature, and the target temperature. This allows the outlet temperature to be adjusted using only one temperature detection device, thereby reducing the complexity, cost, and failure rate of the equipment.

[0085] like Figure 2As shown, in one embodiment, after adjusting the heating element power of the heating device so that the air outlet temperature reaches the second temperature target value, it also includes: when the air outlet temperature is constant at the second temperature target value, obtaining a new first heating element power of the heating device; based on a first mapping relationship between the ambient temperature and the heating element power and the air outlet temperature, determining a new ambient temperature estimate corresponding to the new first heating element power when the air outlet temperature monitoring value is constant at the second temperature target value; based on a second mapping relationship between the air outlet temperature and the ambient temperature and the target temperature, determining a new second temperature target value of the air outlet temperature when the temperature of the target environment reaches the target temperature from the new ambient temperature estimate; adjusting the heating element power of the heating device so that the air outlet temperature reaches the new second temperature target value.

[0086] In this embodiment, as the air outlet temperature is continuously adjusted, the ambient temperature is also constantly changing. In order to stabilize the ambient temperature at the target temperature, in this embodiment, the current air outlet temperature is monitored in real time, and the air outlet temperature is continuously corrected, so that the indoor temperature can always be maintained at the target temperature. The specific air outlet temperature adjustment process is similar to that in the above embodiment, and will not be repeated here to avoid repetition.

[0087] Embodiment 2:

[0088] Based on the contents of the above embodiments, in this embodiment, the heating element power of the heating device is adjusted so that the air outlet temperature reaches the second temperature target value, including: dynamically adjusting the heating element power using a PID algorithm according to the difference between the air outlet temperature monitoring value and the second temperature target value until the air outlet temperature reaches the second temperature target value.

[0089] In this embodiment, the use of the PID algorithm can achieve more precise control of the air outlet temperature, help reduce temperature fluctuations, and maintain the air outlet temperature more stably near the target value, while adjusting the speed more efficiently.

[0090] In one embodiment, the PID algorithm is used to dynamically adjust the power of the heating element according to the difference between the air outlet temperature monitoring value and the second temperature target value, including: obtaining the calculated value of the proportional part, the calculated value of the integral part and the calculated value of the differential part in the PID algorithm according to the difference between the air outlet temperature monitoring value and the second temperature target value; obtaining a comprehensive output value according to the calculated value of the proportional part, the calculated value of the integral part and the calculated value of the differential part; adjusting the power of the heating element according to the preset range of the heating element power, the maximum output value of the PID controller and the comprehensive output value.

[0091] In this embodiment, when adjusting the power of the heating element, the preset range of the heating element power and the maximum output value of the PID controller are taken into consideration, which helps to prevent damage to the heating device or exceeding the safety range of the system due to excessive power adjustment. The specific calculation process is as follows:

[0092] Mathematical model of PID controller: The output u(t) of PID controller consists of three parts: proportional part (P), integral part (I) and differential part (D). The proportional part is proportional to the current error, the integral part is proportional to the accumulation of error, and the differential part is proportional to the rate of change of error.

[0093] The mathematical expression is:

[0094]

[0095] Where e(t) is the current error, i.e., the second temperature target value (T target ) and the outlet temperature monitoring value (T out(t) ), K p is the proportional gain, K i is the integral gain, K d is the differential gain.

[0096] The control process is as follows:

[0097] 1) Initialization: Initialize the parameter K of the PID controller p , K i and K d .

[0098] 2) Real-time detection: The temperature of the air outlet is detected in real time by a temperature sensing device at the air outlet to obtain the measured value of the air outlet temperature.

[0099] 3) Calculate the error e(t):

[0100] e(t)=T target -T out(t)

[0101] 4)PID calculation:

[0102] Proportional part:

[0103] u p (t) = K p e(t)

[0104] Integration part:

[0105]

[0106] Differential part:

[0107]

[0108] Comprehensive output:

[0109] u(t)=u p (t)+u i (t)+u d (t)

[0110] 5) Adjust the heating element power according to the preset range of the heating element power, the maximum output value of the PID controller and the comprehensive output.

[0111] In one embodiment, adjusting the power of the heating element according to the preset range of the power of the heating element, the maximum output value of the PID controller and the comprehensive output value includes: adjusting the power of the heating element according to the following calculation formula:

[0112]

[0113] Where D(t) is the adjusted heating element power, D min and D max are the minimum and maximum values ​​of the heating element power, u max is the maximum output value of the PID controller, and u(t) is the comprehensive output value.

[0114] In this embodiment, the interpolation method can be used to more quickly and accurately calculate the target value of the heating body power to be adjusted, thereby improving the processing efficiency of the system.

[0115] In one embodiment, when the air outlet temperature monitoring value is constant at a preset first temperature target value, the first heating element power of the heating device is obtained, including: according to the difference between the air outlet temperature monitoring value and the first temperature target value, using a PID algorithm to dynamically adjust the heating element power of the heating device until the air outlet temperature monitoring value is constant at the preset first temperature target value, thereby obtaining the first heating element power of the heating device.

[0116] In this embodiment, when the air outlet temperature gradually increases to the first temperature target value, dynamic adjustment using the PID algorithm helps the system reach the first temperature target value more quickly and smoothly, allowing the system to start regulating the air outlet temperature more quickly.

[0117] Embodiment three:

When the heating device receives the target temperature set by the user, it enters the heating mode, and the temperature sensing package monitors the air outlet temperature in real time and transmits it to the controller. At the same time, the power meter also synchronously measures the power of the heating element in real time and transmits it to the controller.

[0122] When the controller detects that the measured value of the air outlet temperature is constant at the first temperature target value, it obtains the heating element power at this time, and determines the ambient temperature estimate value corresponding to the first heating element power when the air outlet temperature monitoring value is constant at the first temperature target value based on the preset first mapping relationship between the ambient temperature and the heating element power and the air outlet temperature; determines the second temperature target value of the air outlet temperature when the temperature of the target environment reaches the target temperature from the ambient temperature estimate value based on the preset second mapping relationship between the air outlet temperature and the ambient temperature and the target temperature; and adjusts the heating element power of the heating device so that the air outlet temperature reaches the second temperature target value.

[0123] In some embodiments, the controller can execute the temperature adjustment method described in any of the above embodiments. To avoid repetition, it will not be described here.
