The embodiments of the present application will be further explained with reference to the drawings.
Referring to fig. 1, fig. 1 is a schematic diagram of an air conditioner according to an embodiment of the present application, where the air conditioner 110 includes:
an ultrasonic transmitter 140 for transmitting ultrasonic waves;
an ultrasonic receiver 120 for receiving ultrasonic waves reflected by the target location;

a control processing part 130 connected with the ultrasonic transmitter, the ultrasonic receiver and the temperature sensing part respectively;
before the air conditioner 110 is started, the control processing component 130 obtains a first time interval between the ultrasonic wave transmitted by the ultrasonic transmitter 140 and the ultrasonic wave received by the ultrasonic receiver 120, and obtains a first distance value from the air conditioner to a target position according to a first temperature value and the first time interval;

In one embodiment, the ultrasonic transmitter 140 may be a common ultrasonic generator, or may be a sound amplifying device capable of generating ultrasonic waves, such as a speaker, and may be capable of generating and transmitting ultrasonic waves. It should be noted that the ultrasonic wave emitter 140 may be disposed inside the air conditioner, or may be disposed outside a casing of the air conditioner, so as to achieve emission of the ultrasonic wave, and details are not repeated herein.

Referring to fig. 7, another embodiment of the present application further provides a control method, which includes, but is not limited to, step S710, step S720, and step S730.
In step S710, a first temperature value from the temperature sensing component is acquired.
It should be noted that, the first temperature value in the embodiment of the method and the subsequent embodiments of the method may refer to the detailed explanation in the embodiment of the apparatus, and will not be described herein again.

In one embodiment, during the cooling or heating process of the air conditioner, the first distance value is kept unchanged due to the fixed target position, in this case, the first distance value is used as the ultrasonic propagation path, the second time interval is the round trip time, and the temperature value of the target position may be calculated from the first temperature value, the first distance value, and the second time interval, or a threshold value may be preset, and if the error between the speed calculated from the first distance value and the second time interval and the first propagation speed corresponding to the first temperature value is smaller than the threshold value, i.e., the speed of the ultrasonic wave does not change much during the actual propagation, it can be considered that the room temperature is stabilized in the second operation state, such as an air conditioner, and is operated for a period of time, such that the temperature of the room approaches a set operating temperature, the temperature of the target location may be derived from the velocity calculated for the first distance value and the second time interval. The temperature of the space where the air conditioner is located in the refrigerating or heating process is uneven, for example, when the air conditioner starts to refrigerate or heat, the difference between the set temperature value and the room temperature is large, the temperature of the air medium is different at the moment, the ultrasonic wave cannot be spread at a constant speed, the temperature of the target position needs to be obtained according to the first temperature value, the first distance value and the second time interval, and the accuracy of temperature measurement is improved.
Another embodiment of the present application further provides a control method, as shown in fig. 8, fig. 8 is a schematic diagram of another embodiment of a refinement procedure of step S720 in fig. 7, where the step S720 includes, but is not limited to:
step S810, determining a first propagation speed of the ultrasonic wave according to the first temperature value;
in step S820, a first distance value from the air conditioner to the target location is obtained according to the first propagation speed and the first time interval.
In an embodiment, a first mapping relation table between a temperature value and an ultrasonic propagation speed may be locally stored in the control processing unit, and when the first temperature value is obtained in step S810, since the indoor temperature may be assumed to be uniform when the air conditioner is turned on, the ultrasonic propagation speed obtained by looking up the mapping relation table is the first propagation speed at which the ultrasonic propagates at a uniform speed indoors. Certainly, the air conditioner can also be connected with the server through a WIFI module of the air conditioner, and the first propagation speed corresponding to the first temperature value is inquired from the server.
In an embodiment, since the temperature in the air conditioner is uniform before the air conditioner is started, in the environment, the ultrasonic wave propagates at a constant speed, the distance along which the ultrasonic wave propagates can be calculated in step S820 by using the first propagation speed and the first time interval, for example, the first time interval in this embodiment is the time interval from the transmission of the ultrasonic wave to the reception of the ultrasonic wave, so that the time interval of one pass of the ultrasonic wave in this embodiment is half of the first time interval, and the distance obtained by multiplying the time interval by the first propagation speed value is the first distance value, thereby implementing automatic acquisition of the parameters required by the initialization setting of ultrasonic temperature measurement.
To illustrate by way of a specific example, the first propagation speed is V1, the first time interval is T1, the time taken for the ultrasonic wave to be transmitted to the target position is T1/2, and the first distance value L is V1 (T1/2).
Another embodiment of the present application further provides a control method, as shown in fig. 9, fig. 9 is a schematic diagram of an embodiment of a refinement flow of step S730 in fig. 7, where the step S730 includes, but is not limited to:
step S910, obtaining a second propagation velocity of the ultrasonic wave according to the first distance value and the second time interval;
step S920, determining a temperature value of the target location according to the first temperature value and the second propagation speed.
In an embodiment, the second time interval in step S910 is a time when the ultrasonic wave travels to and from the air conditioner and the target location during the cooling or heating process of the air conditioner, so the second propagation speed is obtained by dividing the first distance value by half of the second time interval.
In an embodiment, if the temperature of the space and the distance between the target location and the air conditioner satisfy a linear relationship, in step S920, the average temperature is an arithmetic average value between the temperature of the location where the air conditioner is located and the temperature of the target location, so as to calculate the temperature of the target location, or calculate according to other mathematical models, specifically adjust according to the temperature distribution of the space where the air conditioner is located, and through the calculation of the second propagation speed and the first temperature value, the obtained temperature value of the target location can be closer to the actual temperature of the target location, which is beneficial for the air conditioner to adjust the working state according to the temperature subsequently, so as to achieve accurate temperature adjustment.
Another embodiment of the present application further provides a control method, as shown in fig. 10, fig. 10 is a schematic diagram of another embodiment of a refinement procedure of step S920 in fig. 9, where step S920 includes, but is not limited to:
step S1010, determining a second temperature value according to the second propagation speed;
step S1020, obtaining a temperature value of the target location according to the first temperature value and the second temperature value.
In an embodiment, the determining the second temperature value by the second propagation speed in step S1010 may be obtained by querying the first mapping table, and since the temperature of each area in the space where the air conditioner is located is different in the cooling or heating process, based on the above embodiment, the second propagation speed is an average speed of ultrasonic propagation, and thus the obtained second temperature value is an average temperature in the ultrasonic propagation path, and the determining the second temperature value by the first mapping table can improve the efficiency of data acquisition.
In an embodiment, there may be multiple implementation manners in the step S1020 of obtaining the temperature value of the target location according to the first temperature value and the second temperature value, and a simpler one is when the space temperature and the distance are in a linear relationship, in this case, since the second temperature value is an average temperature, that is, an arithmetic average of the first temperature value and the temperature value of the target location is the second temperature value, the temperature value of the target location may be obtained according to the second temperature value and the first temperature value.
Another embodiment of the present application further provides a control method, as shown in fig. 11, after the step S730 in fig. 7 is executed, the method further includes the following steps:
step S1110, establishing a mapping relationship between the time interval and the temperature according to the second time interval and the temperature value of the target location.
Based on the above embodiment, the temperature value of the target location may be calculated according to the first temperature value and the second temperature value, but the process needs to perform table lookup and calculation for multiple times, and a certain calculation time needs to be consumed, while the air conditioner and the target location are fixed locations, that is, the first distance value is kept unchanged in most cases, under this condition, the corresponding relationship between the second time interval and the temperature value of the target location is unique, that is, the second time interval obtained at different temperatures is uniquely corresponding to the temperature value of the target location. It should be noted that after the mapping relationship is established, after the second time interval is obtained in S730 in the above embodiment, a query may be performed from the mapping relationship, if a corresponding temperature value can be matched, the temperature value is directly set as the temperature value of the target location for subsequent air conditioner control, and if a corresponding result cannot be matched, the obtaining of the temperature value of the target location is completed according to the method in the above embodiment, and the mapping relationship between the time interval and the temperature is newly added in the form, so that the operating efficiency is effectively improved.
Another embodiment of the present application further provides a control method, as shown in fig. 12, fig. 13 is a schematic diagram of another embodiment of a refinement procedure of step S720 in fig. 7, where the step S720 includes, but is not limited to:
step 1210, obtaining a first distance value for a plurality of times;
in step S1220, when the difference between the last obtained first distance value and the currently obtained first distance value is greater than the first set threshold, the first distance value from the air conditioner to the target location is updated by using the last obtained first distance value.
In an embodiment, in the actual use process, there may be an obstacle between the air conditioner and the target position, for example, the target position is a point on the ground, when an article is placed in the target position in the actual use process, the first distance value obtained by the ultrasonic ranging is changed, so in the execution process of step S720, the obstacle needs to be identified, and a large error in the measured temperature due to the existence of the obstacle is avoided.
In an embodiment, in step S1210, the first distance value may be obtained once at a preset time interval, and the specific time interval may be adjusted and set according to actual requirements. It should be noted that, in the step S1210, obtaining the first distance value for multiple times is that when the air conditioner is turned on, if the air conditioner is in a cooling or heating process, it is not necessary to determine an obstacle, and the obtained first distance value is used for performing subsequent operations. It should be noted that, if the difference between the two first distance values is smaller than the first set threshold, the distance between the air conditioner and the target position is only slightly changed, and the change of the first distance value does not significantly affect the ultrasonic temperature measurement of the air conditioner, and at this time, the currently obtained first distance value may be used for subsequent air conditioner control.
In an embodiment, the data of the first setting threshold in step S1220 may be adjusted according to actual requirements, and is not described herein again. If the difference between the last obtained first distance value and the currently obtained first distance value is greater than a first set threshold, the distance between the air conditioner and the target position is greatly changed, it can be determined that an obstacle appears between the air conditioner and the target position, and the distance for ultrasonic ranging is reduced, the currently obtained first distance value is the first distance value under the condition that the obstacle exists, and the first distance value should be the first distance value obtained last time when the obstacle is eliminated.
In an embodiment, in order to further improve the accuracy of detecting the obstacle, the step S1220 may further use the first distance value for three times to determine the difference, which is described as a specific example below:
the air conditioner acquires 3 times of first distance values which are respectively recorded as L1, L2 and L3, the first set threshold value is recorded as Y, and it is known that no obstacle exists between the air conditioner and the target position when the first distance value L1 is measured for the first time, if | L1-L2| > Y and | L2-L3| > Y, an obstacle exists in the target position when L2 is acquired, and if | L1-L3| > Y, an obstacle exists in the target position when L3 is acquired and is inconsistent with the obstacle when L2 is acquired, and then the subsequent steps are executed by taking L1 as the first distance value; if | L1-L3| < Y, the obstacle has been cleared when L3 is obtained, and then the subsequent steps are executed by using L3 as the first distance value, so that inaccuracy of the measured first distance value due to the obstacle can be avoided, and the accuracy of the air conditioner in obtaining the first distance value is effectively improved.
