To further illustrate the technical solution of the present invention, the following specific examples are provided in conjunction with fig. 1 to 5.
Referring to fig. 4, the present embodiment provides a method for calibrating adaptive timing with high precision of an air conditioner, including:
the air conditioner controller receives real-time information T and set timing information Ts sent by an air conditioner remote controller;
the air conditioner controller synchronizes the current time according to the real-time information T;
the method comprises the steps that the air conditioner controller obtains the current environment temperature, obtains the time frequency deviation delta f corresponding to the current environment temperature according to a preset time frequency deviation-environment temperature curve delta f-t (shown in figure 3), and carries out time correction on the air conditioner controller according to the time frequency deviation delta f;
the air conditioner controller performs timing of the set timing information Ts according to the corrected time.
Referring to fig. 2, the air conditioner self-adaptive timing high-precision calibration method of the embodiment is suitable for timing by an air conditioner controller without a crystal oscillator, and realizes the precision of the air conditioner controller executing the timing function of the air conditioner remote controller by calibrating time by the crystal oscillator of the air conditioner controller.
The air conditioner remote controller of the embodiment needs to be used for timing operation by a user, so that the time is required to be kept accurate, the air conditioner remote controller with time timing achieves high-accuracy timing by utilizing a crystal oscillator of the air conditioner remote controller, and the air conditioner remote controller can send time information T and set timing information Ts to the air conditioner controller when the air conditioner is remotely controlled each time.
And the air conditioner controller synchronizes the current time according to the real-time information T so as to keep the accuracy of the current time. Because the air conditioner controller utilizes the built-in oscillator to carry out timing frequency deviation and causes errors due to the influence of ambient temperature, the time frequency deviation is corrected through a preset time frequency deviation-ambient temperature curve delta f-t, and therefore the accuracy of the timing process is guaranteed.
Therefore, the self-adaptive timing high-precision calibration method of the air conditioner in the embodiment realizes the calibration of the current time according to the received real-time information T, and the calibration of the time frequency deviation is carried out through the preset time frequency deviation-environment temperature curve delta f-T, so that the calibration of the timing process is realized, the air conditioner controller utilizes the air conditioner remote controller to carry out the time precision calibration, and the timing accuracy of the air conditioner controller is ensured.
Further, in this embodiment, the obtaining the time-frequency deviation Δ f corresponding to the current ambient temperature according to the preset time-frequency deviation-ambient temperature curve Δ f-t includes:
the air conditioner controller extracts a time frequency deviation rate delta fn under each temperature interval t (n-1) to tn according to a preset time frequency deviation-environment temperature curve delta f-t, and the time frequency deviation rate delta fn is represented by [ t (n-1) to tn and delta fn ];
discretizing the time frequency deviation-environment temperature curve delta f-t to obtain [ t 0-t 1, delta f1], [ t 1-t 2, delta f2], [ t 2-t 3, delta f3], [ t (n-1) -tn, delta fn ];
and judging the temperature interval in which the temperature is positioned according to the acquired environment temperature t to obtain the time frequency deviation delta f corresponding to the temperature interval.
Specifically, as an optional implementation manner of this embodiment, the method for calibrating the adaptive timing and the high precision of the air conditioner in this embodiment includes:
after the air conditioner controller is powered on for the first time, the air conditioner controller initializes a frequency deviation-temperature curve delta f-t, namely, time frequency deviation under each temperature interval is extracted, for example, the time frequency deviation from t0 temperature to t1 temperature interval is delta f1, which is represented by [ t 0-t 1, delta f1], and parameters such as [ t 0-t 1, delta f1], [ t 1-t 2, delta f2], [ t 2-t 3, delta f3], [ t (n-1) -tn, delta fn ] and the like can be obtained by discretizing the curve; for example, the time frequency deviation of 20 degrees to 25 degrees is-0.20%, which is expressed by [20 to 25, -0.20% ].
And after the air conditioner controller receives the time information T and the set timing information Ts sent by the air conditioner remote controller, the time T starts to be corrected according to the time frequency deviation corresponding to the current ambient temperature, namely, the time T is corrected according to delta f seconds per second. For example, the following steps are carried out: the air conditioner remote controller sends the current time of 10, 00, the timing setting is 11.
Further, in the high-precision calibration method for adaptive timing of an air conditioner according to this embodiment, in the process of timing according to the set timing information Ts, when it is obtained that the ambient temperature enters the second ambient temperature interval from the first ambient temperature interval, the air conditioner controller updates the time frequency deviation Δ f to a time frequency deviation value corresponding to the second ambient temperature interval, and updates the time correction value at the same time. Therefore, if the ambient temperature continuously changes, the time-frequency deviation is updated in real time as the ambient temperature enters a new temperature interval, and the time correction value is updated at the same time.
After the calibration process is executed, the timing accuracy of the air conditioner controller has reached a relatively high level, and in order to continuously improve the timing accuracy, the time frequency deviation of each temperature interval also needs to be calibrated synchronously, in the following manner: the air conditioner remote controller can synchronously send time information to the air conditioner controller after each remote control, after the air conditioner controller receives new time information, the time of the air conditioner remote controller is firstly synchronized, the time of the air conditioner remote controller is accurate because the time of the air conditioner remote controller is timed by a crystal oscillator, so the air conditioner controller needs to synchronize the time of the remote controller, and secondly, the frequency deviation rate of the air conditioner controller is corrected.
Further, the air conditioner adaptive timing high-precision calibration method of the embodiment includes performing deviation rate correction for the time-frequency deviation Δ f:
the air conditioner controller receives two times of time information T1 and T2 with time intervals sent by an air conditioner remote controller;
the air conditioner controller calculates a time difference value delta T1 of the air conditioner remote controller according to the time information T1 and T2, and the time difference value delta T2 of the air conditioner controller is corrected according to a time frequency deviation-environment temperature curve delta f-T;
judging whether the following conditions are met: and delta T1= delta T2, if the judgment result is yes, the time frequency deviation of the air conditioner controller is accurate, correction is not needed, and if the judgment result is no, the time frequency deviation of the air conditioner controller has an error and needs to be corrected.
Further, in this embodiment, the performing of the deviation ratio correction on the time-frequency deviation Δ f includes:
when the air conditioner controller receives the time information T1 and T2 sent by the air conditioner remote controller twice and is in the same environment temperature interval;
the air conditioner controller judges that delta T1 is not equal to delta T2, and according to a correction formula: and updating the time frequency deviation-environment temperature curve delta f-t.
Further, the performing of the deviation ratio correction for the time-frequency deviation Δ f according to this embodiment includes:
when the air conditioner controller receives two times of time information T1 and T2 sent by the air conditioner remote controller and is in two or more than two environment temperature intervals;
the air conditioner controller judges that the delta T1 is not equal to the delta T2, and according to a correction formula: and calculating correction time frequency deviation, and calculating correction time frequency deviation corresponding to each environment temperature interval according to a formula, wherein a, b, 8230, and n are time intervals of time information T1 to T2 in each environment temperature interval.
Further, the air conditioner controller of the present embodiment, according to the correction formula:
correction time-frequency deviations Δ f1', Δ f2'. DELTA fn-1' for n-1, respectively, at time intervals a, b, \\8230,;
and calculating a corrected time-frequency deviation delta fn ' corresponding to the time interval N of the Nth environment temperature interval according to the formula delta f ' = a multiplied by delta f1' + b multiplied by delta f2' +. + -. + N multiplied by delta fn '.
For example, when the air conditioner controller receives two times of time information T1 and T2 sent by the air conditioner remote controller, the time information T1 and T2 are in a first environment temperature interval [ T0-T1, Δ f1] and a second environment temperature interval [ T1-T2, Δ f2];
the air conditioner controller calculates that the time interval of the two times of time information T1 and T2 in a first environment temperature interval T0-T1 is a, and the time interval in a second environment temperature interval T1-T2 is b;
calculating the correction time frequency deviation of the first environment temperature interval t 0-t 1;
and calculating the frequency deviation calibration value of the second environment temperature interval t 1-t 2 according to a formula.
Therefore, according to the time frequency deviation calibration value obtained by the method for calibrating the self-adaptive timing high precision of the air conditioner, a high-precision time frequency deviation-temperature curve can be obtained, and high-precision timing can be further realized; the newly obtained time frequency deviation-temperature curve needs to be stored, so that the latest frequency deviation-temperature curve can be directly adopted after power is cut off and power is on.
As can be seen from the above, the deviation ratio correction is performed for the time-frequency deviation Δ f in the present embodiment according to the following two cases:
1) If the time update of two remote controls is in a temperature interval: firstly, calculating the time difference value of the two remote controllers as delta T1, and the time difference value after self calibration of the air conditioner controller as delta T2, wherein if the delta T1= delta T2, the self-calibrated time frequency deviation is proved to be zero deviation and does not need to be updated; if Δ T1 ≠ Δ T2, it is indicated that the time-frequency deviation of self-calibration has an error, and needs to be corrected, and the correction formula is as follows:
and at the same time updating the time-frequency deviation-temperature curve Δ f-t, e.g. the temperature interval is t 0-t 1, then [ t 0-t 1, [ Δ f1]]Will be updated to [ t 0-t 1,. DELTA.f 1']；
2) If the time update of the two remote controls is in two or more temperature intervalsThe method comprises the following steps: firstly, calculating the time difference value of the two remote controllers as delta T1, and the time difference value after self calibration of the air conditioner controller as delta T2, wherein if the delta T1= delta T2, the self-calibrated time frequency deviation is proved to be zero deviation and does not need to be updated; if Δ T1 ≠ Δ T2, it indicates that the time-frequency deviation of self-calibration has an error, and needs to be corrected, and the correction formula is as follows:
however, since the temperature intervals are spanned, the frequency deviation values of the temperature intervals are jointly influenced, which involves analyzing a multi-linear equation, for example, the time at the 1 st temperature interval is a, for example, the time at the 2 nd temperature interval is b,. For example, the time at the nth temperature interval is n, then the multi-linear equation is: Δ f ' = a × Δ f1' + b × Δ f2' +. + n × Δ fn ', because a and b.. N are calculable values, and Δ f1' and Δ f2'. Δ fn ' need to be solved, and to analyze the values, the calculated values in case 1) are used, and the n-element primary equation, and if n-1 element values are known, the remaining n-th value can be calculated. By way of example: suppose that two temperature intervals are spanned, which are respectively [ t 0-t 1, delta f1]、[t1～t2，Δf2]And the controller can calculate the time staying in the temperature interval from t0 to t1 as a, the time staying in the temperature interval from t1 to t2 as b, and the frequency deviation value calibrated before t0 to t1 as Δ f1', then the frequency deviation calibration value (based on the equation) for the temperature interval from t1 to t2 can be calculated>
