FIG. 1 is a flow chart of an embodiment of the present invention.
Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Thus, a feature indicated in this specification will serve to explain one of the features of one embodiment of the invention, and does not imply that every embodiment of the invention must have the stated feature. Further, it should be noted that this specification describes many features. Although some features may be combined to show a possible system design, these features may also be used in other combinations not explicitly described. Thus, the combinations illustrated are not intended to be limiting unless otherwise specified.
The principles of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Fig. 1 is a flowchart of an embodiment of the present invention, which specifically corrects indoor ambient temperature detected by a line controller, and utilizes the advantage that the line controller is closer to a human activity space, so as to detect a temperature in a closest range of human activity, and meanwhile, avoid the problem that the detected ambient temperature is inaccurate due to heat generated by the line controller itself.
In this embodiment, the temperature sensor of the indoor unit is selected as a standard sensor in the same environment as the temperature sensor of the line controller, and since the temperature sensor of the indoor unit is connected to the main board of the indoor unit through a long connecting line and is placed at the air return opening of the indoor unit, the temperature sensor is not affected by heat generated by devices such as the main board of the indoor unit, and the temperature detection is relatively accurate.
In this embodiment, the detected temperature of the line controller is corrected after the air conditioner is turned off for a certain time, so as to ensure that the air conditioner does not affect the temperature of the indoor environment, and in addition to ensure that the air conditioner does not affect the temperature of the indoor environment, it is also ensured that each device of the line controller is restored from a heating state to a normal state, so as to ensure that the air conditioner does not affect the temperature of the indoor environment, and at the same time, it is required to determine whether the time that the line controller is turned off before entering the normal operating mode or the time that the line controller is in the low power consumption mode is greater than or equal to a second preset time, which is 10 minutes in the specific embodiment of fig. 1.
And then, calculating an inherent difference value, and calculating the difference value of the temperature difference of the indoor environment detected by the temperature sensor of the indoor unit and the temperature sensor of the wire controller at least once as the inherent difference value when the temperature sensor of the wire controller enters a normal working mode. In a preferred embodiment, it is preferable that the temperature sensor of the indoor unit performs a plurality of detections, and the temperature sensor of the line controller performs a plurality of detections, so as to obtain a plurality of differences and average the differences to obtain a more accurate intrinsic difference. In actual operation, immediately after the line controller recovers communication with the indoor unit (before the line controller device heats), reading the temperature value Cm1 detected by the temperature sensor of the indoor unit and the temperature value Cm2 detected by the temperature sensor of the line controller at the moment, and after reading m (in one embodiment, the value of m is 10) times (once every 1 second), calculating the ' inherent difference ' Cx = ' between the temperature detected by the temperature sensor when the line controller does not heat and the temperature detected by the temperature sensor of the indoor unit
The 'inherent difference' is caused by the individual difference and the position difference of the wire controller and the internal machine sensor, and is a relatively stable difference along with the change of the indoor temperature.
Then, after the on-line controller enters a normal working mode and a first preset time passes, calculating a temperature difference value of an indoor environment detected by a temperature sensor of the indoor unit and a temperature sensor of the line controller as a heating difference value, wherein the first preset time is a time for keeping the heating temperature of each device of the on-line controller stable, and a specific skilled person in the art can set the heating difference value according to different models of each line controller, and in a preferred embodiment, the heating difference value is also the most preferredIt is preferable to detect and calculate the average value of the differences a plurality of times. In this embodiment, the first preset time is 10 minutes, after the line controller enters the normal operation mode for 10 minutes, the heat generation of the devices such as the main board is basically stable, at this time, the temperature value Cn1 detected by the temperature sensor of the indoor unit and the temperature value Cn2 detected by the temperature sensor of the line controller are read again, after n (in this embodiment, the value of n is 10) times is read (once every 1 second), the "heat generation difference" Cy = between the temperature detected by the temperature sensor and the temperature detected by the temperature sensor of the indoor unit when the heat generation of the line controller is stable is calculated
And/n, the heating difference Cy comprises a sensor temperature rise value caused by the heating of the wire controller and an 'inherent difference' between the wire controller and the internal machine.
And subtracting the inherent difference from the heating difference to obtain a corrected value, and subtracting the corrected value from the temperature of the indoor environment detected by the temperature sensor of the line controller after the line controller enters a working mode and the first preset time is passed, so that the temperature detected by the temperature sensor of the line controller can be corrected to obtain more accurate indoor environment temperature. The specific calculation process is that the temperature Cz = Cy-Cx which needs to be corrected by the temperature sensor in the normal working mode of the line controller is calculated, so that the finally used temperature value in the normal working mode of the line controller is equal to the temperature value detected by the current temperature sensor minus the correction value Cz.
It should be noted that the above-mentioned correction process needs to be detected for a certain time after the air conditioner is turned off, so as to prevent the difference between the temperatures detected by the indoor unit and the line controller from being unstable due to the uneven change of the indoor temperature field caused by the influence of the previous temperature adjustment of the air conditioner after the air conditioner is turned on, and thus the calculation of the correction value is affected. In the embodiment shown in fig. 1, the air conditioner is turned off for half an hour, and then the line controller is controlled to enter the low power consumption mode for 10 minutes, so that the air conditioner is ensured not to influence the temperature of the indoor environment, and meanwhile, each device of the line controller does not generate heat any more.
In a specific embodiment of the correction method of the present invention, the correction method of the present invention may be executed when the air conditioner is turned on again after the air conditioner is turned off and the duration of the turn-off is greater than or equal to the third preset time, or may be executed when the air conditioner is turned on again after the air conditioner is turned off and the duration of the turn-off is greater than or equal to the third preset time, so that a problem that a correction effect is affected by a change of a temperature error caused by various changes may be avoided. Specifically, the third preset time may be set by a person skilled in the art according to actual needs, and only needs to ensure that the time for turning off the air conditioner does not affect the temperature of the indoor environment any more, and in the embodiment shown in fig. 1, the third preset time is half an hour.
The invention protects the air conditioner which adopts the correction method to correct the detection environment temperature of the wire controller of the air conditioner besides the correction method, the air conditioner is an air conditioner comprising a wire controller, an indoor unit of the air conditioner is connected with the wire controller through a communication wire, a user controls the running state of the indoor unit through the wire controller, both the indoor unit and the wire controller of the air conditioner are provided with a temperature sensor (also called as a temperature sensing part), the temperature of the temperature sensor of the linear controller is corrected by the temperature sensor of the indoor unit, of course, the temperature sensor to be corrected in the present invention is not limited to the temperature sensor of the line controller, and may be an air conditioner having a remote controller, the remote controller may be an air conditioner component for correcting the ambient temperature detected by a temperature sensor included in the remote controller, or may be another air conditioner component for detecting the indoor ambient temperature.
Taking the line controller as an example, since the present invention has a plurality of times to be counted, in one embodiment, a timer for timing various states of the air conditioner and/or the line controller may be provided in the line controller.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
