Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments, it being understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention.
In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in itself. Thus, "module", "component" or "unit" may be used mixedly.
In order to solve the problem in the related art that the accuracy of the mode of determining the ambient temperature cannot be guaranteed by correcting the ambient temperature acquired by the remote controller or the temperature acquired by the temperature sensor on the unit, an embodiment of the present invention provides an ambient temperature monitoring method, as shown in fig. 1, the method includes:
s101, acquiring a first environment temperature acquired by a remote controller and a second environment temperature acquired by a unit;
s102, judging whether the first environment temperature is successfully acquired or not; if yes, executing step S103; if not, executing step S104;
step S103, determining an ambient temperature according to the first ambient temperature and the second ambient temperature;
and step S104, determining the ambient temperature according to the second ambient temperature.
In the embodiment, a first ambient temperature acquired by a remote controller and a second ambient temperature acquired by a unit are acquired; judging whether the first environment temperature is successfully acquired or not; if yes, determining the ambient temperature according to the first ambient temperature and the second ambient temperature; if not, determining the ambient temperature according to the second ambient temperature. Therefore, when the first environment temperature is acquired successfully, the environment temperature can be determined according to the first environment temperature and the second environment temperature instead of the environment temperature determined according to the first environment temperature or the second environment temperature singly, and the reference parameter for determining the environment temperature is increased, so that the finally determined environment temperature is more accurate. On the premise of accurately determining the ambient temperature, the operation of the unit is controlled, so that the comfort of a user is further ensured.
It should be noted that, in step S101, acquiring the first ambient temperature collected by the remote controller and the second ambient temperature collected by the unit includes: the method comprises the steps of obtaining a first environment temperature collected by a remote controller every other preset time period, and obtaining a second environment temperature collected by an environment temperature detection device on a unit every other preset time period.
The remote controller can also be a wire controller, and the remote controller can be subordinate to the unit or a device independent of the unit. The remote controller can be arranged at any position in the space where the unit is arranged, and only the remote controller can be in communication connection with the unit. The second ambient temperature accessible is located the ambient temperature detection device collection on the unit, and ambient temperature detection device can be located the return air inlet department of unit. The ambient temperature detection means may be a temperature sensor or a bulb. The unit may be an air conditioner. And the preset time period can be set by a user according to actual needs and the environment where the unit is located. When the ambient temperature fluctuation is large, both preset time periods may be short, for example: the preset time period may be 10 minutes. And the two preset time periods may also be different. The preset time period may be a fixed time period or different time periods. For example, each time ten minutes apart. Alternatively, ten minutes, five minutes, three minutes, etc. The effect of accurately and timely acquiring the first ambient temperature and the second ambient temperature can be achieved.
In one possible implementation, as shown in fig. 2, the step S103 of determining the ambient temperature according to the first ambient temperature and the second ambient temperature includes:
step S201, judging whether the unit is running; if yes, go to step S202; if not, executing step S203;
step S202, correcting the first ambient temperature and the second ambient temperature respectively, and determining the ambient temperature;
step S203; an average of the first ambient temperature and the second ambient temperature is determined as the ambient temperature.
It can be understood that if the unit is running, due to reasons such as cooling or heating of the unit, there will be a certain difference between the temperature near the unit and the ambient temperature, so that the difference between the first ambient temperature and the actual ambient temperature is relatively large, and the ambient temperature can be determined in a correction manner. If the unit is not operating, the average of the first ambient temperature and the second ambient temperature may be taken directly. To reduce errors. Thereby, the accuracy of determining the ambient temperature may be improved. The following example describes how the first ambient temperature and the second ambient temperature are modified.
In one possible implementation manner, as shown in fig. 3, in step S202, the first ambient temperature and the second ambient temperature are respectively corrected, and determining the ambient temperature includes:
step S2021, respectively correcting the first ambient temperature and the second ambient temperature according to the ambient temperature correction value;
step S2022, comparing the corrected first ambient temperature value with the corrected second ambient temperature value; and determining the ambient temperature according to the comparison result.
As shown in fig. 4, the step S2021 of correcting the first ambient temperature and the second ambient temperature according to the ambient temperature correction value includes:
step S401, determining a first ambient temperature correction value and a second ambient temperature correction value;
the environment temperature correction value comprises a first environment temperature correction value and a second environment temperature correction value;
s402, detecting the current operation mode of the unit, and determining a correction strategy corresponding to the operation mode;
and S403, respectively correcting the first environmental temperature and the second environmental temperature by using the first environmental temperature correction value and the second environmental temperature correction value according to the correction strategy.
Wherein, the operation mode includes: a cooling operation mode and a heating operation mode.
It should be noted that the first ambient temperature correction value and the second ambient temperature correction value may be determined through multiple experiments, and the correction values may have a certain difference for units of different models and different regions. When the unit is in a heating mode, the temperature at the air return opening is higher than the actual environment temperature, and when the unit is in a cooling mode, the temperature at the air return opening is lower than the actual environment temperature. Therefore, if the corrected temperature needs to be closer to the ambient temperature, different correction strategies need to be adopted in different operation modes. After the correction, the corrected first ambient temperature value and the corrected second ambient temperature value can be compared; and determining the ambient temperature according to the comparison result. Thereby, a reference parameter for determining the ambient temperature is added, so that the finally determined ambient temperature is more accurate. On the premise of accurately determining the ambient temperature, the operation of the unit is controlled, so that the comfort of a user is further ensured. For example: when the unit is a fixed-frequency air conditioner, the unit can be stopped when the ambient temperature reaches the set temperature. Accurate determination of the ambient temperature may allow the unit to be shut down for an extended period of time, or properly, to ensure user comfort.
In one possible implementation manner, when the operation mode is the cooling operation mode, the first ambient temperature and the second ambient temperature are respectively corrected by using the first ambient temperature correction value and the second ambient temperature correction value according to a correction strategy by using the following formulas:
Tix＝TXi+ΔTXi-1；
Tih＝Thi+ΔThi-1；
in one possible implementation manner, when the operation mode is the heating operation mode, the first ambient temperature and the second ambient temperature are respectively corrected by using the first ambient temperature correction value and the second ambient temperature correction value according to the correction strategy by using the following formula:
Tix＝TXi-ΔTXi-1；
Tih＝Thi-ΔThi-1；
wherein, TixThe corrected first environment temperature value; t isihThe corrected second ambient temperature value; t isXiIs a first ambient temperature value, ThiA second ambient temperature value; delta TXi-1Is a first ambient temperature correction value; delta Thi-1A second ambient temperature correction value; i is a positive integer, and i represents the number of times the first ambient temperature and the second ambient temperature are obtained.
It will be appreciated that when the unit is in the cooling mode, the temperature at the return air inlet will be lower than the actual ambient temperature, and when the unit is in the heating mode, the temperature at the return air inlet will be higher than the actual ambient temperature. And when the first environment temperature value and the second environment temperature value are higher than the environment temperature in the heating mode, the correction strategy is that the first environment temperature value subtracts the first environment temperature correction value, and the second environment temperature value subtracts the second environment temperature correction value, so as to obtain more accurate environment temperature.
It should be noted that the first ambient temperature correction value is determined by the following formula:
ΔTXi-1＝(Thi-1-TXi-1)；
the second ambient temperature value correction value is determined by the following formula:
ΔThi-1＝(Thi-1-TXi-1)/2；
wherein, Thi-1The second ambient temperature obtained last time; t isXi-1A first ambient temperature obtained for a previous time; when i is 1, Thi-1、TXi-1Respectively representing the second ambient temperature and the first ambient temperature which are obtained last time before the unit operates. The above formula can be determined through a plurality of experiments before the unit leaves the factory, so as to further determine an accurate correction value, and the finally determined environment temperature is closer to the actual environment temperature.
In one possible implementation manner, as shown in fig. 5, in step S2022, the corrected first ambient temperature value and the corrected second ambient temperature value are compared; determining the ambient temperature based on the comparison comprises:
step S501, comparing whether the corrected first environment temperature value is less than or equal to the corrected second environment temperature value; if yes, go to step S502; if not, go to step S503;
step S502, determining a first environment temperature value as an environment temperature;
and S503, determining the second ambient temperature value as the ambient temperature.
It can be understood that, the smaller value of the two corrected temperature values is determined as the ambient temperature, so that the error can be further reduced, and the accuracy of determining the ambient temperature is improved.
In one possible implementation, the step S104, if no, determining the ambient temperature according to the second ambient temperature includes: correcting the second environment temperature according to the second environment temperature correction value; and determining the corrected second ambient temperature value as the ambient temperature.
Therefore, when the first environment temperature cannot be acquired due to the situations of the placement position of the remote controller, insufficient electric quantity and the like, the second environment temperature can be corrected, and the corrected second environment temperature can be determined as the environment temperature.
Fig. 6 shows an ambient temperature monitoring apparatus according to an embodiment of the present invention, the apparatus is used for performing the method shown in the above embodiment, and the apparatus includes:
the acquisition module 601 is configured to acquire a first ambient temperature acquired by a remote controller and a second ambient temperature acquired by a unit;
a determining module 602, configured to determine whether the first ambient temperature is successfully obtained; if yes, determining the ambient temperature according to the first ambient temperature and the second ambient temperature; if not, determining the ambient temperature according to the second ambient temperature.

If the unit is not operating, the average of the first ambient temperature and the second ambient temperature may be taken directly. To reduce errors. Thereby, the accuracy of determining the ambient temperature may be improved.
In a possible implementation manner, the determining module 602 is further configured to correct the first ambient temperature and the second ambient temperature according to the corrected ambient temperature value; comparing the corrected first ambient temperature value with the corrected second ambient temperature value; and determining the ambient temperature according to the comparison result.
Therefore, when the first environment temperature is acquired successfully, the environment temperature can be determined according to the first environment temperature and the second environment temperature instead of the environment temperature determined according to the first environment temperature or the second environment temperature singly, and the reference parameter for determining the environment temperature is increased, so that the finally determined environment temperature is more accurate. On the premise of accurately determining the ambient temperature, the operation of the unit is controlled, so that the comfort of a user is further ensured.
