The invention provides a compensation method for a temperature detection value. The method can be used for the electric appliances needing temperature detection. Such as an air conditioner.
Fig. 1 is a schematic method diagram of an embodiment of a method for compensating a temperature detection value according to the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the method for compensating the temperature detection value at least includes step S110, step S120 and step S130.
Step S110, a first temperature variation curve of the pre-configured ambient temperature with time is obtained.
Specifically, a first temperature variation curve of the current area, which is changed along with the time of the ambient temperature in one day within a preset time period before the current time (within a period of the preset time period), is obtained in advance through big data analysis, or a first temperature variation curve of the current area, which is changed along with the time of the ambient temperature in one day within a preset time period before the current time, is detected in advance through temperature detection equipment.
The environmental temperature has different trends with time in different seasons, and the preset time period may be N days before the current time, for example, 20 days. For example, the environmental temperatures of the current area at different times of each day within 20 days before the current time are obtained through big data, then a first temperature change curve of the environmental temperature changing with time in one day is drawn according to the obtained average value of the environmental temperatures at different times of each day within 20 days before the current time, or the environmental temperatures of the current area at different times of each day within 20 days before the current time and detected by a temperature detection device are obtained, and then the first temperature change curve of the environmental temperature changing with time in one day is drawn according to the obtained average value of the environmental temperatures at different times of each day within 20 days before the current time.
And step S120, generating a second temperature change curve of the environmental temperature changing along with time according to the detected environmental temperature.
Specifically, the detected ambient temperature value includes a temperature value obtained by compensating an actual ambient temperature detection value. Alternatively, the compensation value used for compensation may be the compensation value used for last compensation or the preset compensation value.
More specifically, the second temperature change curve is generated according to an ambient temperature value (a temperature value obtained by compensating an actual ambient temperature detection value) detected within a preset time before the current time. For example, the current time is 12:00, and generating a second temperature change curve of the change of the environmental temperature along with the time according to the environmental temperature value detected in three hours before the current time (namely from 10:00 to 12: 00). Or generating the second temperature change curve according to an environmental temperature value (a temperature value obtained by compensating an actual environmental temperature detection value) detected from a preset time to a current time. For example, the preset time is 0:00, and the current time is 12:00, generating a second temperature change curve of the change of the environmental temperature along with the time according to the environmental temperature value detected between 00:00 and 12: 00.
For example, referring to FIG. 2a, a temperature variation curve of a certain area from 0:00 to 24:00 a day (i.e., 0:00 the next day) is shown. The curve 1 is a first temperature variation curve of the environmental temperature changing with time, which is configured in advance, and the curve 2 is a second temperature variation curve of the environmental temperature changing with time, which is generated according to the detected environmental temperature.
Step S130, comparing the first temperature variation curve with the second temperature variation curve to determine a compensation value of the current ambient temperature detection value.
In one embodiment, comparing whether the absolute value of the difference between the temperature values of the first temperature change curve and the second temperature change curve at the current moment is within a preset range; if the absolute value of the difference of the temperature values is within a preset range, determining the compensation value of the environment temperature detection value as a preset compensation value; and/or determining a compensation value of the corresponding environment temperature detection value according to the absolute value of the difference of the temperature values at the current moment if the absolute value of the difference of the temperature values is not in a preset range. That is, if the absolute value of the difference between the temperature values is within a preset range, normally compensating the current ambient temperature detection value according to a preset compensation value; and if the absolute value of the difference of the temperature values is not in the preset range, correcting and compensating the current environment temperature detection value according to the absolute value of the difference of the temperature values at the current moment.
Specifically, determining the compensation value of the detected ambient temperature value according to the absolute value of the difference between the temperature values at the current time includes: and determining a compensation value corresponding to the absolute value of the difference between the temperature values at the current moment according to the preset corresponding relationship between the absolute value of the difference between different temperature values and the compensation value. For example, if the absolute value of the difference between the temperature values is 3 ℃, the corresponding compensation value is 1 ℃, if the absolute value of the difference between the temperature values is 4 ℃, the corresponding compensation value is 0.5 ℃, and if the absolute value of the difference between the temperature values is 5 ℃, the corresponding compensation value is 0 ℃. That is, the larger the absolute value of the difference between the temperature values at the present time of the first temperature change curve and the second temperature change curve is, the smaller the compensation value of the corresponding ambient temperature detection value is. Therefore, the temperature change rate can be reduced, and the detection precision can be improved. When the temperature control device is applied to a unit (such as an air conditioning unit) controlled according to the ambient temperature, the temperature can be gradually and suddenly increased, so that the unit can stably operate.
Optionally, determining a compensation value of the detected ambient temperature value according to an absolute value of a difference between the temperature values at the current time, further includes: and comparing the environmental temperature value detected at the current moment with the environmental temperature value detected at the last detection moment, and determining the compensation direction for compensating the current environmental temperature value. Optionally, the ambient temperature value detected at the current moment is compared with the ambient temperature value detected at the last detection moment according to the second temperature curve. The environment temperature value detected at the current moment comprises a temperature value obtained by compensating the actual environment temperature detection value at the current moment. Alternatively, the compensation value used for compensation may be the compensation value used for last compensation or the preset compensation value. The environmental temperature value detected at the last detection moment comprises a temperature value obtained by compensating the actual environmental temperature detection value at the last detection moment.
Specifically, if the ambient temperature value detected at the current time is greater than the ambient temperature value detected at the previous detection time, the compensation direction is positive compensation, that is, the compensation temperature value is a positive value, and if the ambient temperature value detected at the current time is less than the ambient temperature value detected at the previous detection time, the compensation direction is negative compensation, that is, the compensation temperature value is a negative value. That is, in the case of a sudden increase in temperature, the compensation direction is positive compensation, and in the case of a sudden decrease in temperature, the compensation direction is negative compensation.
For example, if the absolute value of the difference between the temperature values of the first temperature variation curve and the second temperature variation curve at the current time is 3 ℃, the corresponding compensation value is 1 ℃, and the ambient temperature value detected at the current time is greater than the ambient temperature value detected at the last detection time, and then the compensation value is +1 ℃.
And step S140, compensating the current environment temperature detection value according to the determined compensation value to obtain a compensated current environment temperature value.
Specifically, the current ambient temperature detection value is added to the determined compensation value to obtain a compensated current ambient temperature value. For example, if the current ambient temperature detection value is 26 ℃, the determined compensation value is +0.5 ℃, and the compensated current ambient temperature value is 26.5 ℃.
The method of the present invention will be described below with a specific example, in which the predetermined compensation value is set to 1 ℃ and the range allowed by the absolute value of the difference between the predetermined temperature values is set to [0 ℃, 2 ℃), and Δ T is 0 ℃ to 2 ℃.
If the temperature change curve of the day obtained by big data analysis in advance is the curve 1 shown in fig. 2b, the temperature change curve obtained in the actual temperature detection process is the curve 2 shown in fig. 2b, the temperature at 12:00 in the curve 1 is 24 ℃, the temperature at 12:00 in the curve 2 (the temperature is the compensated temperature, the actual ambient temperature detection value is 24 ℃ after compensation, the adopted compensation value can be the compensation value determined when the compensation value is determined last time or the preset compensation value) is 24 ℃, the difference between the two is 0 ℃ and is within the preset range [0 ℃ and 2 ℃), therefore, the compensation value is determined to be the preset compensation value 2 ℃, namely, normal compensation is adopted, and the compensated ambient temperature detection value at 12:00 is 24 ℃.
If the temperature change curve of the day obtained by big data analysis in advance is a curve 1 as shown in fig. 2c, the temperature change curve obtained in the actual temperature detection process is a curve 2 as shown in fig. 2c, the temperature change curve obtained in the actual temperature detection process is as shown in fig. 2c, at the time of 12:00, the temperature at the time of 12:00 in the curve 1 is 24 ℃, the temperature at the time of 12:00 in the curve 2 (the temperature is the compensated temperature, the actual ambient temperature detection value is 25 ℃, the temperature is 27 ℃ after compensation is performed according to the preset compensation value 1 ℃, the adopted compensation value can be the compensation value determined when the compensation value is determined last time or the preset compensation value) is 27 ℃, the difference between the two values is 3 ℃ and is not within the preset range [0 ℃ and 2 ℃), and the temperature at the time of 12:00 is larger than the ambient temperature value detected at the last detection time according to the curve 2, then the compensation value of the environment temperature detection value detected by the temperature detection device is +0.5 ℃, and the current environment temperature value is 25.5 ℃ after the environment temperature detection value is compensated according to the compensation value.
The invention also provides a compensation device for the temperature detection value. The device can be used for the electric appliances needing temperature detection. Such as an air conditioner.
Fig. 3 is a block diagram of a compensation apparatus for temperature detection values according to an embodiment of the present invention. As shown in fig. 3, the compensation device 100 for the temperature detection value includes: an acquisition unit 110, a generation unit 120, a determination unit 130 and a compensation unit 140.
The acquiring unit 110 is configured to acquire a first temperature variation curve of a pre-configured ambient temperature along with time variation; the generating unit 120 is configured to generate a second temperature variation curve of the ambient temperature along with time according to the detected ambient temperature value; the determining unit 130 is configured to compare the first temperature variation curve with the second temperature variation curve to determine a compensation value of the current ambient temperature detection value; the compensation unit 140 is configured to compensate the current ambient temperature detection value according to the compensation value determined by the determination unit 130, so as to obtain a compensated current ambient temperature value.
The acquisition unit 110 acquires a first temperature change curve of a pre-configured ambient temperature change with time. Specifically, a first temperature variation curve of the current area, which is changed along with the time of the ambient temperature in one day within a preset time period before the current time (within a period of the preset time period), is obtained in advance through big data analysis, or a first temperature variation curve of the current area, which is changed along with the time of the ambient temperature in one day within a preset time period before the current time, is detected in advance through temperature detection equipment.
The environmental temperature has different trends with time in different seasons, and the preset time period may be N days before the current time, for example, 20 days. For example, the environmental temperatures of the current area at different times of each day within 20 days before the current time are obtained through big data, then a first temperature change curve of the environmental temperature changing with time in one day is drawn according to the obtained average value of the environmental temperatures at different times of each day within 20 days before the current time, or the environmental temperatures of the current area at different times of each day within 20 days before the current time and detected by a temperature detection device are obtained, and then the first temperature change curve of the environmental temperature changing with time in one day is drawn according to the obtained average value of the environmental temperatures at different times of each day within 20 days before the current time.
The generation unit 120 generates a second temperature change curve of the change of the ambient temperature with time based on the detected ambient temperature. Specifically, the detected ambient temperature value includes a temperature value obtained by compensating an actual ambient temperature detection value. Alternatively, the compensation value used for compensation may be the compensation value used for last compensation or the preset compensation value.
More specifically, the generation unit 120 generates the second temperature change curve according to an ambient temperature value (a temperature value obtained by compensating an actual ambient temperature detection value) detected within a preset time before the current time. For example, the current time is 12:00, and generating a second temperature change curve of the change of the environmental temperature along with the time according to the environmental temperature value detected in three hours before the current time (namely from 10:00 to 12: 00). Or generating the second temperature change curve according to an environmental temperature value (a temperature value obtained by compensating an actual environmental temperature detection value) detected from a preset time to a current time. For example, the preset time is 0:00, and the current time is 12:00, generating a second temperature change curve of the change of the environmental temperature along with the time according to the environmental temperature value detected between 00:00 and 12: 00.
For example, referring to FIG. 2a, a temperature variation curve of a certain area from 0:00 to 24:00 a day (i.e., 0:00 the next day) is shown. The curve 1 is a first temperature variation curve of the environmental temperature changing with time, which is configured in advance, and the curve 2 is a second temperature variation curve of the environmental temperature changing with time, which is generated according to the detected environmental temperature.
The determining unit 120 compares the first temperature variation curve with the second temperature variation curve to determine a compensation value of the current ambient temperature detection value.
In one embodiment, comparing whether the absolute value of the difference between the temperature values of the first temperature change curve and the second temperature change curve at the current moment is within a preset range; if the absolute value of the difference of the temperature values is within a preset range, determining the compensation value of the environment temperature detection value as a preset compensation value; and/or determining a compensation value of the corresponding environment temperature detection value according to the absolute value of the difference of the temperature values at the current moment if the absolute value of the difference of the temperature values is not in a preset range. That is, if the absolute value of the difference between the temperature values is within a preset range, normally compensating the current ambient temperature detection value according to a preset compensation value; and if the absolute value of the difference of the temperature values is not in the preset range, correcting and compensating the current environment temperature detection value according to the absolute value of the difference of the temperature values at the current moment.
Specifically, the determining unit 120 determines the compensation value of the ambient temperature detection value according to the absolute value of the difference between the temperature values at the current time, including: and determining a compensation value corresponding to the absolute value of the difference between the temperature values at the current moment according to the preset corresponding relationship between the absolute value of the difference between different temperature values and the compensation value. For example, if the absolute value of the difference between the temperature values is 3 ℃, the corresponding compensation value is 1 ℃, if the absolute value of the difference between the temperature values is 4 ℃, the corresponding compensation value is 0.5 ℃, and if the absolute value of the difference between the temperature values is 5 ℃, the corresponding compensation value is 0 ℃. That is, the larger the absolute value of the difference between the temperature values at the present time of the first temperature change curve and the second temperature change curve is, the smaller the compensation value of the corresponding ambient temperature detection value is. Therefore, the temperature change rate can be reduced, and the detection precision can be improved. When the temperature control device is applied to a unit (such as an air conditioning unit) controlled according to the ambient temperature, the temperature can be gradually and suddenly increased, so that the unit can stably operate.
Optionally, the determining unit 120 determines the compensation value of the detected ambient temperature value according to the absolute value of the difference between the temperature values at the current time, and further includes: and comparing the environmental temperature value detected at the current moment with the environmental temperature value detected at the last detection moment, and determining the compensation direction for compensating the current environmental temperature value. Optionally, the ambient temperature value detected at the current moment is compared with the ambient temperature value detected at the last detection moment according to the second temperature curve. The environment temperature value detected at the current moment comprises a temperature value obtained by compensating the actual environment temperature detection value at the current moment. Alternatively, the compensation value used for compensation may be the compensation value used for last compensation or the preset compensation value. The environmental temperature value detected at the last detection moment comprises a temperature value obtained by compensating the actual environmental temperature detection value at the last detection moment.
Specifically, if the ambient temperature value detected at the current time is greater than the ambient temperature value detected at the previous detection time, the compensation direction is positive compensation, that is, the compensation temperature value is a positive value, and if the ambient temperature value detected at the current time is less than the ambient temperature value detected at the previous detection time, the compensation direction is negative compensation, that is, the compensation temperature value is a negative value. That is, in the case of a sudden increase in temperature, the compensation direction is positive compensation, and in the case of a sudden decrease in temperature, the compensation direction is negative compensation.
For example, if the absolute value of the difference between the temperature values of the first temperature variation curve and the second temperature variation curve at the current time is 3 ℃, the corresponding compensation value is 1 ℃, and the ambient temperature value detected at the current time is greater than the ambient temperature value detected at the last detection time, and then the compensation value is +1 ℃.
The compensation unit 140 compensates the current ambient temperature detection value according to the determined compensation value to obtain a compensated current ambient temperature value.
Specifically, the compensation unit 140 adds the current ambient temperature detection value to the determined compensation value to obtain a compensated current ambient temperature value. For example, if the current ambient temperature detection value is 26 ℃, the determined compensation value is +0.5 ℃, and the compensated current ambient temperature value is 26.5 ℃.
