Description

Technical Field

[0001] The present application belongs to the field of electronic digital data processing technology, and in particular relates to a temperature control method, device, temperature controller and storage medium. Background Art

[0002] The operating principle of a temperature controller is primarily based on the automatic sampling and real-time monitoring of ambient temperature by a temperature sensor. The device then uses electrical signals to control the heating or cooling device to maintain a set temperature range. The core function of a temperature controller is to achieve automatic temperature control, and it has a wide range of applications, such as dry-type transformers and industrial production process control.

[0003] Currently, for example, in the scenario of dry-type transformers, a temperature controller is required to maintain a constant temperature of the dry-type transformer. Although a temperature controller is added, in reality, when the temperature falls below the target temperature range, turning on the heating device will not immediately raise the temperature to the target temperature. The same is true when turning on the cooling device. There will be a certain degree of delay, resulting in the temperature not being within the target temperature range. Summary of the Invention

[0065] The embodiment of the present application provides a temperature control method, Figure 1 This is a schematic diagram of the temperature control method provided in one embodiment of the present application, with reference to Figure 1 , the temperature control method is described in detail as follows:

[0066] Step 101: Acquire a historical temperature sequence of a target transformer and a current temperature of the target transformer.

[0067] Exemplarily, step 101 may include:

[0068] Obtain the historical temperature sequence of the target transformer and the temperature acquisition value of the target transformer.

[0069] Based on the historical temperature sequence, multiple historical temperatures are obtained;.

[0070] Based on the plurality of historical temperatures and a preset normal temperature, an average value of the historical abnormal temperatures and an average value of the historical normal temperatures are determined.

[0071] The difference between the mean of historical abnormal temperatures and the mean of historical normal temperatures is calculated to obtain the corrected temperature.

[0072] If the difference between the temperature collection value and the average of the historical abnormal temperatures is less than or equal to the average of the temperature collection value and the historical normal temperatures, the current temperature is obtained based on the temperature collection value and the corrected temperature.

[0073] If the difference between the temperature collection value and the average of the historical abnormal temperatures is greater than the average of the temperature collection value and the historical normal temperatures, the temperature collection value is used as the current temperature.

[0074] In some specific embodiments, the operation of the temperature controller may be subject to various interferences, which may cause errors in the acquired temperature. These abnormal values ​​need to be processed to obtain the true and closest value of the current temperature. This makes the acquired data more accurate, allowing the temperature controller to control the temperature according to the accurate data and ensure the accuracy of temperature control.

[0075] Step 102: Based on the historical temperature sequence, obtain the temperature change rate and temperature variance.

[0076] Exemplarily, based on the historical temperature sequence, the temperature change rate is obtained, including:

[0077] Get the time interval between two adjacent temperatures in the historical temperature series.

[0078] For any set of two adjacent temperatures in the historical temperature sequence, a first rate is calculated based on the two adjacent temperatures and the time interval in combination with the third formula.

[0079] Calculate the average of all first rates and record it as the temperature change rate.

[0080] The third formula can be:

[0081]

[0082] Wherein, ν represents the first rate, T1 represents the temperature obtained earlier than the other two adjacent temperatures, T2 represents the temperature obtained later than the other two adjacent temperatures, and s represents the time interval.

[0083] In some specific embodiments, the magnitude of the first rate is positive or negative, and the values ​​are added when calculating the average. When the calculated average is positive, it indicates that the trend of temperature change is warming. Similarly, when the calculated average is negative, it indicates that the trend of temperature change is cooling.

[0084] For example, obtaining the temperature variance based on the historical temperature series may include:

[0085] Based on the historical temperature sequence, multiple historical temperatures are obtained.

[0086] Calculate the variance of multiple historical temperatures to obtain the temperature variance.

[0087] Step 103 : Calculate the device startup time based on the temperature change rate, the current temperature, and the target temperature range.

[0088] Exemplarily, step 103 may include:

[0089] Based on the temperature change rate, the current temperature and the target temperature interval, a first time is obtained; wherein the first time represents the time from the current temperature to the target temperature interval edge condition according to the temperature change rate.

[0090] The difference between the heater or cooler startup delay and the first time is calculated to obtain the device startup time.

[0091] In some specific embodiments, when the heater and cooler are first started, they cannot immediately increase or decrease the temperature of the target transformer. Therefore, it is necessary to take this time difference into account in the startup time. The startup delay of the heater or cooler can be calculated based on historical data and then the average value is obtained.

[0092] Exemplarily, obtaining the first time based on the temperature change rate, the current temperature, and the target temperature range may include:

[0093] When the temperature change rate is greater than 0, the first time is obtained based on the temperature change rate, the current temperature, and the upper limit of the target temperature range in combination with the first formula.

[0094] When the temperature change rate is less than or equal to 0, the first time is obtained based on the temperature change rate, the current temperature, and the lower limit of the target temperature range in combination with the second formula.

[0095] The first formula can be:

[0096]

[0097] Wherein, t1 represents the first time, C1 represents the upper limit of the target temperature range, T represents the current temperature, and ν represents the temperature change rate.

[0098] The second formula can be:

[0099]

[0100] Wherein, C2 represents the lower limit of the target temperature range.

[0101] Step 104 : Based on the temperature variance, the device on-time, and the temperature change rate, the heater or the cooler is controlled to be on or off to control the temperature of the target transformer.

[0102] Exemplarily, step 104 may include:

[0103] If the temperature variance is less than the preset threshold, the heater or cooler is not activated.

[0104] If the temperature variance is greater than or equal to the preset threshold, it is determined whether the temperature change rate is greater than 0. If the temperature change rate is greater than 0, the cooler is turned on and the heater is turned off according to the device startup time to control the temperature of the target transformer.

[0105] If the temperature change rate is less than or equal to 0, the heater is turned on and the cooler is turned off according to the device start time to control the temperature of the target transformer.

[0106] In some specific embodiments, the temperature variance is calculated using a conventional calculation method. The temperature variance is used to determine whether the temperature change is a normal small fluctuation or a change that may fall outside the target temperature range, thereby facilitating control of the heater or cooler according to the device startup time.

[0107] The above temperature control method calculates the temperature change rate and temperature variance based on the historical temperature sequence of the target transformer, accurately determines whether to start the heater or cooler based on the temperature variance, and determines whether to start the heater or cooler based on the temperature change rate. The device startup time is calculated based on the temperature change rate, the current temperature, and the target temperature range. By calculating the accurate device startup time, the heater or cooler can be activated when the temperature drops to the boundary of the target temperature range, so that the temperature is maintained within the target temperature range, thereby achieving the purpose of stably and accurately controlling the temperature within the target temperature range.

[0108] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
