The invention provides a temperature regulation time prediction method.
In the first embodiment of the present invention, as shown in fig. 1, the temperature adjustment time prediction method includes the steps of:
step S100, acquiring the current outside temperature, the current inside temperature and the set temperature of a user;
the outside temperature is the temperature of the medium before the temperature is adjusted by the temperature adjusting device, and the inside temperature is the temperature of the medium after the temperature is adjusted by the temperature adjusting device. For example, when the temperature adjusting device is an air conditioner, the outside temperature is the outdoor air temperature, and the inside temperature is the indoor air temperature; when the temperature adjusting device is a water heater, the outside temperature is the temperature of water before heating, and the inside temperature is the temperature of water after heating. The user set temperature is a target temperature of the medium set by the user. Wherein, outside temperature and inboard temperature can be obtained through the testing result of the temperature sensor who sets up in the thermoregulation device outside and inboard respectively, and user's set temperature can read from user's setting instruction.
Step S200, calculating the prediction time required for the inner side temperature to reach the set temperature according to the outer side temperature, the inner side temperature and the set temperature;
specifically, the predicted time is related to the difference between the inside temperature and the set temperature, and the larger the absolute value of the difference between the inside temperature and the set temperature is, the longer the predicted time is. Meanwhile, the prediction time is also related to the heat transfer condition of the temperature adjustment device, and in general, the more the outside temperature interferes with the inside temperature as the absolute value of the difference between the outside temperature and the inside temperature increases, and the longer the prediction time is in the case where other conditions are not changed.
And step S300, displaying the predicted time.
And after the predicted time is calculated, displaying the predicted time so that a user can know the time required by the inner side temperature to reach the set temperature, and improving the interaction performance of the temperature adjusting equipment. Specifically, there are various ways to display the predicted time. In a specific example, the duration of the calculated predicted time may be displayed directly. In another specific example, the time length left from the current time to the time when the inside temperature reaches the set temperature may be displayed in real time in a countdown manner according to the calculated time length of the predicted time and the time length difference between the current time and the time when the outside temperature, the inside temperature and the set temperature are obtained. In still another specific example, the predicted time when the inside temperature reaches the set temperature may be calculated from the time when the outside temperature, the inside temperature, and the set temperature, which are used in the acquisition calculation, and the length of the predicted time, and may be directly displayed.
In this embodiment, the temperature adjustment time prediction method includes the steps of: acquiring the current outside temperature, the current inside temperature and the set temperature of a user; calculating the prediction time required for the inner side temperature to reach the set temperature according to the outer side temperature, the inner side temperature and the set temperature; the predicted time is displayed. According to the invention, the predicted time for the inner side temperature to reach the set temperature is calculated and displayed according to the outer side temperature, the inner side temperature and the set temperature of the user, so that the user can simply and clearly know the time for the temperature adjusting equipment to adjust the temperature to the set temperature, the interactivity between the temperature adjusting equipment and the user is improved, and the user experience is improved.
In the second embodiment of the present invention, as shown in fig. 2, after step S300, the temperature adjustment time prediction method further includes the steps of:
s400, acquiring the current inside temperature and the set temperature of a user;
step S500, when the absolute value of the difference between the inside temperature and the set temperature is greater than or equal to the preset temperature difference, acquiring the current outside temperature;
the process returns to step S200.
During operation of the temperature regulating device, the rate of temperature change typically varies with changes in heat transfer conditions; in addition, when the predicted time is calculated, in order to simplify the calculation process and improve the calculation efficiency, the specific calculation method is also simplified to a certain extent, and the factors all cause the calculated predicted time to be inconsistent with the actual situation. In this embodiment, after the predicted time is displayed, the current inside temperature and the set temperature of the user are obtained, and when the inside temperature does not reach the set temperature, specifically, whether the inside temperature reaches the set temperature is determined by determining whether an absolute value of a difference between the inside temperature and the set temperature is smaller than a preset temperature difference. When the absolute value of the difference between the inside temperature and the set temperature is greater than or equal to the preset temperature difference, the outside temperature is obtained, and the predicted time is recalculated to update the previously calculated predicted time, so that the calculation of the predicted time is adapted to the change of relevant operating parameters in the temperature adjusting equipment or the change of user set parameters on the one hand, and the predicted applicability is improved; on the other hand, the prediction time is obtained in a mode of repeated iterative computation, so that the prediction accuracy is improved, and the user experience is improved.
In the third embodiment of the present invention, as shown in fig. 3, after step S300, the temperature adjustment time prediction method further includes the steps of:
step S600, receiving a set temperature of a user;
step S700, when receiving the set parameters of the user, acquiring the current outside temperature and the current inside temperature;
the process returns to step S200.
In the operation process of the temperature adjusting device, a user may change parameters such as set temperature at any time according to the change of the self requirement, and at the moment, the predicted time calculated according to the set temperature initially set by the user cannot reflect the time when the inner side temperature reaches the set temperature after the user changes the set temperature. Therefore, in this embodiment, when the set temperature of the user is received, the current outside temperature and the current inside temperature are obtained, and the prediction time is calculated according to the outside temperature, the inside temperature and the set temperature, so that the prediction time is updated, the prediction of the temperature adjustment device can meet the change of the user requirement at any time, the prediction accuracy is improved, and the interactivity between the temperature adjustment device and the user experience are improved.
In a fourth embodiment of the present invention, as shown in fig. 4, the temperature adjustment time prediction method further includes the steps of:
step S810, receiving the set time of a user;
step S820, comparing the set time with the predicted time;
and step S830, when the absolute value of the difference between the set time and the predicted time is greater than the preset time difference, changing the temperature adjustment rate according to the outside temperature, the inside temperature and the set temperature so that the absolute value of the difference between the set time and the predicted time is less than or equal to the preset time difference.
In this embodiment, the user can set the setting time for the inside temperature to reach the set temperature according to the user's own needs. When the temperature adjusting equipment adjusts the temperature according to the preset default operation parameters, if the predicted time is not consistent with the set time, the operation parameters of the temperature adjusting equipment are modified so as to meet the requirement of a user on the time when the inner side temperature reaches the set temperature, the interactivity between the temperature adjusting equipment and the user is further improved, and the user experience is improved. Specifically, when the absolute value of the difference between the set time and the predicted time is greater than the preset time difference, it indicates that the temperature adjusting rate of the temperature adjusting device is relatively fast, in a specific example, when the user has no special requirement for the minimum value of the temperature adjusting time, the temperature adjusting device may be controlled to maintain the original default operation parameters to operate, and in this case, the temperature adjusting device may complete the temperature adjustment within the set time of the user. Of course, in another specific example, the default operating parameters may be changed, the rate of temperature adjustment may be slowed, and the predicted time and the set time may be adapted to avoid discomfort to the user due to too fast a temperature adjustment. When the difference between the predicted time and the set time is larger than the preset time difference, the temperature adjusting speed is increased, so that the temperature adjusting equipment can finish the temperature adjustment within the set time of a user, and the use requirement of the user is met.
In a fifth embodiment of the present invention, as shown in fig. 5, when the temperature adjustment time prediction method is applied to an air conditioner, the temperature change rate may be adjusted by adjusting an operating frequency of a compressor or a rotational speed of an indoor fan, and specifically, step S830 includes:
step S831, when the difference between the set time and the predicted time is larger than the preset time difference, reducing the running frequency of a compressor of the air conditioner or reducing the rotating speed of an indoor fan of the air conditioner;
and step S832, when the difference between the predicted time and the set time is greater than the preset time difference, increasing the running frequency of the compressor or increasing the rotating speed of the indoor fan.
In a sixth embodiment of the present invention, as shown in fig. 6, when the temperature adjustment time prediction method is applied to a water heater, the temperature adjustment rate can be changed by adjusting the heating power of the water heater, for example, changing the heating electric power of the water heater, the air intake amount of the gas water heater, and other parameters, and specifically, step S830 includes:
step S833, when the difference between the set time and the predicted time is larger than the preset time difference, reducing the heating power of the water heater;
and step S834, when the difference between the predicted time and the set time is larger than the preset time difference, improving the heating power of the water heater.
In the above embodiment of the present invention, step S200 includes the steps of:
step S210, calculating a rate coefficient K according to the outside temperature T1, the inside temperature T2 and the set temperature Ts;
step S220, calculating a first coefficient m according to the outside temperature T1 and the inside temperature T2;
in step S230, the predicted time T is calculated from T ═ m × T2-Ts |/K.
Further, step S210 includes:
step S211, accumulating the running time tr after the startup;
step S212, judging whether the running time tr is less than the preset time t 0;
if yes, go to step S213, read the pre-stored rate coefficient K0 as the rate coefficient K;
if not, executing the step S214, and calculating a second coefficient n according to the outside temperature T1 and the inside temperature T2; in step S215, the rate coefficient K is calculated from K ═ n × T2-Ts |/tr.
Wherein the first coefficient m and the second coefficient n reflect the influence of the difference between the inside temperature and the outside temperature on the temperature regulation process, and both the first coefficient m and the second coefficient n are related to the difference between the outside temperature and the inside temperature. In the initial stage of the operation of the temperature adjusting device, reading a prestored speed coefficient K0 as a speed coefficient K, changing the speed coefficient K along with the operation of the temperature adjusting device due to the change of operation parameters or environment parameters, and correcting the speed coefficient according to K-n-T2-Ts/tr to improve the accuracy of the speed coefficient K. Furthermore, when the predicted time T is calculated according to T ═ m × T2-Ts |/K, the first coefficient m and the rate coefficient K are updated values obtained according to the current outside temperature, inside temperature and set temperature, so that the accuracy of the calculation of the predicted time is improved.
