The operation effect of the air conditioner is influenced by various factors; the installation position of the air conditioner can greatly influence an indoor temperature field, an indoor wind field and an indoor humidity field, so that the thermal comfort of a human body is greatly influenced. For example, the installation location of a wall-mounted air conditioner in a user's home may be a middle position, a leftmost position, a rightmost position, a middle position near the left, and a middle position near the right of the wall.
Although a user can manually input the installation position information of the air conditioner into the air conditioner, the existing manual input operation is more complicated; the existing air conditioner still cannot automatically judge the installation position of the air conditioner.

For example, as shown in fig. 1, when the air conditioner is installed on the leftmost side and the rightmost side of the wall a, the sensors of the air conditioner may form blind detection areas in the wall B direction and the wall C direction due to the blocking of the wall B and the wall C, respectively, and then the data collection of the sensors in the wall B direction and the wall C direction is affected.

Referring to fig. 3, a first embodiment of an infrared sensor adjustment method according to the present invention includes the following steps:
step S10, when the air conditioner receives the detection instruction determined by the installation position, the infrared sensor is started;
step S20, controlling the infrared sensor to scan a target area so as to acquire temperature data of the target area and position information of a human body heat source in the target area;
the infrared sensor is a related sensor with an infrared sensing function, and is preferably arranged on an indoor unit of the air conditioner; understandably, the infrared sensor is used for scanning a temperature field of a target area (mainly referred to as an indoor environment) and acquiring related temperature detection data; from the detection data, a corresponding infrared scan thermal image may be generated. The infrared sensor preferably adopts a multi-array thermopile infrared sensor.
For example, when the air conditioner is started for the first time to activate the system or restore factory settings, a detection instruction determined by the installation position is automatically triggered and sent to a microprocessor of the air conditioner, and the microprocessor sends a corresponding start instruction to the infrared sensor, so that the infrared sensor is started and scans.
Step S20 specifically includes:
step S21, controlling the infrared sensor to scan a target area to obtain temperature data of the target area;
and when the infrared sensor scans the target area, acquiring temperature values of all point positions in the target area corresponding to all array points of the infrared sensor. Optionally, each time the infrared sensor scans the target area, the temperature data of the target area is acquired again, and the temperature data of the target area acquired in the past is replaced.
Step S22, judging whether a human body heat source exists in the target area according to the temperature data of the target area;
because the temperature of the human body heat source is different from the ambient temperature of the target area to a certain extent, the human body heat source with the temperature data different from the ambient background temperature can be determined from the infrared scanning thermal image of the target area.
And step S23, when the human body heat source exists in the target area, determining the position information of the human body heat source.
For example, a human body heat source is marked on an infrared scanning thermal image of a target area, a corresponding marking point is formed, and the position of the marking point on the infrared scanning thermal image is determined. Specifically, the relative position relationship between the mark point and a certain reference line (point) may be determined. The related position relation can reflect the position of the human body heat source mark point on the infrared scanning thermal image.
After step S20, step S30 is performed: determining the installation position of the air conditioner according to the temperature data of the target area and the position information of the human body heat source;
when the air conditioner works, under the action of air flow blown out by the indoor unit (the air flow blown out by default in the embodiments of the invention is normal-temperature air flow or cold air flow), a sub-area with the temperature lower than other indoor environment temperature is inevitably existed in the front area of the air outlet direction of the indoor unit; therefore, the low-temperature subarea in the target area is determined according to the temperature data of the target area, and the first class inference result of the installation position of the air conditioner is obtained in a reverse-deducing mode.
Since the installed air conditioners (indoor units) can be regarded as being fixed in position, and the moving range of the human body heat source in the target area is limited, the position of the human body heat source in the target area can be regarded as being approximately fixed. Therefore, different human body heat sources can be detected through the infrared sensor and the positions of the human body heat sources can be determined; furthermore, the distribution situation of the positions of the human body heat sources is counted to determine the moving range of the human body heat sources, and then a second type of interruption result of the installation position of the air conditioner is obtained in a reverse-thrust mode.
And comparing the first class inference result with the second class inference result, and if the first class inference result and the second class inference result are consistent, proving that the two class inference results are consistent, thus determining that the installation position of the air conditioner is the installation position of the air conditioner, which is the first class (or the second class) inference result. Details of step S20 are described in other embodiments below.
It should be noted that the installation position of the air conditioner in each embodiment of the present invention refers to a specific spatial position of the air conditioner in a certain area, and belongs to a broad concept. For example, as shown in fig. 1, the installation position of the air conditioner is installed at the leftmost side of the wall a; in this case, the air conditioner may be placed on the ground near the a-wall or installed on the a-wall.
Step S40, adjusting the detection angle of the infrared sensor according to the installation position of the air conditioner; wherein, infrared sensor sets up on the air conditioner for scan target area.
In each embodiment of the invention, the detection angle of the infrared sensor refers to an included angle between the propagation direction of infrared light emitted by the infrared sensor and a vertical section of an indoor unit body of an air conditioner. The detection angle of the default infrared sensor is 90 degrees, namely the transmission direction of the infrared light emitted by the infrared sensor is vertical to the vertical section of the air conditioner indoor unit body.
In step S40, the detection angle of the infrared sensor is adjusted according to the installation position of the air conditioner. The infrared sensor is used for scanning a target area to acquire the temperature data of the target area and the position information of the human body heat source.
Before step S40, the method further includes: judging whether the detection angle of the infrared sensor needs to be adjusted or not according to the installation position of the air conditioner and a preset association rule between the detection angle of the infrared sensor and the installation position of the air conditioner; then the steps are executed: and adjusting the detection angle of the infrared sensor.
For example, one association rule is: (1) when the installation position of the air conditioner is at the leftmost side or the rightmost side, the detection angle of the infrared sensor needs to be adjusted; the detection angle of the infrared sensor does not need to be adjusted at other positions. (2) And when the mounting position of the air conditioner is at the leftmost side or the rightmost side, adjusting the detection angle of the infrared sensor so as to enable the infrared sensor to face the position of the human body heat source for detection. Referring to fig. 1, since the air conditioner is installed on the leftmost side of the wall a, the detection direction of the infrared sensor needs to be adjusted from 01 to 02, and the detection angle of the infrared sensor needs to be adjusted from 1 to 2.
Therefore, the detection angle of the infrared sensor is adjusted according to the installation position of the air conditioner. Understandably, after the step S40, the steps S20 and the following steps may be re-executed so as to re-determine the human body heat source position, the air conditioner installation position, and the re-adjustment of the detection angle of the infrared sensor after the detection angle adjustment of the infrared sensor.
In this embodiment, the installation position of the air conditioner is determined according to the temperature data of the target area and the position information of the human body heat source; based on the installation position of the air conditioner, the detection angle of the infrared sensor is adjusted, the influence of the installation position of the air conditioner on the automatic determination of the installation position of the air conditioner is overcome, the detection blind area of the infrared sensor is reduced, the infrared sensor can face the position of a human body heat source to detect, the detection precision of the air conditioner sensor is improved, and the air conditioner is controlled more optimally.
Further, as shown in fig. 4, based on the first embodiment of the infrared sensor adjusting method of the present invention, in the second embodiment of the infrared sensor adjusting method of the present invention, one specific implementation of step S30 includes:
step S31, according to the temperature data of the target area, determining a low-temperature sub-area in the target area when the infrared sensor scans the target area, and determining the position of the low-temperature sub-area in the target area to obtain a first class inference result of the installation position of the air conditioner;
specifically, traversing the temperature values of each array point of the infrared sensor, and finding out the array point of which the temperature value exceeds a preset threshold (such as 1.8 ℃) with the adjacent array point; if the area of the area formed by the connection of the adjacent searched array points is less than 2 x2 (i.e. 2 array points in the horizontal and vertical directions) or 3 x 3 (i.e. 3 array points in the horizontal and vertical directions), such array points are not used as the array points of the low-temperature sub-area. In this way, low temperature sub-regions in the target region are determined, such as the bold solid line boxed regions Z1-Z5 in FIGS. 5-1 through 5-5.
The following is an example with reference to FIGS. 5-1 to 5-5. 5-1 through 5-5, each array point (Xi, Yi) has a corresponding temperature value (in:. degree. C.), for example, 24.9 ℃ for (X2, Y3) in FIG. 5-1; in addition, the area of each array point is divided into one to five areas (the specific division mode refers to actual experience or experimental data). The low temperature sub-regions in the figures are found according to the above rules, namely the thick solid line boxed regions Z1-Z5. Further, the air conditioner installation position is deduced according to the position of the low-temperature subarea in the target area, and a first type of deduction result is obtained. Specifically, the interval (including one to five zones) of the main distribution of the low-temperature subintervals is determined; one to five regions correspond to different installation positions respectively, and the installation position of the air conditioner is deduced according to the different installation positions. For example, the low temperature sub-region Z2 in fig. 5-2 is located in one and two zones, but since the area of the low temperature sub-region Z2 in one zone is larger, it is determined that it is located mainly in one zone. If the low-temperature sub-region is uniformly distributed in different regions (such as a first region and a second region), it is determined that the low-temperature sub-region is mainly located in the first region or the second region.
A relational table of a first type of inference results of the installation position of the air conditioner based on the position of the low temperature sub-area in the target area is shown in Table 1:
TABLE 1
Step S32, counting the position distribution condition of the human body heat source according to the position of the human body heat source;
step S33, obtaining a second class interruption result of the installation position of the air conditioner according to the position distribution condition of the human body heat source;
steps S32, S23 and S31 are not necessarily in a sequential relationship, and may be in a sequential or parallel relationship.
6-1-6-5, the inside of the box represents the detection range of the infrared sensor of the air conditioner based on infrared scanning thermal image simulation, and the inside of the box comprises the mark points of each human body heat source, the included angle between L1 and L5 is 180 degrees, the included angle between L3 and L1 and L5 is 90 degrees, L2 represents the leftmost boundary of the area where the human body heat source detected by the infrared sensor is located, L4 represents the rightmost boundary of the area where the human body heat source detected by the infrared sensor is located, namely, the detected human body heat sources are distributed in the area between L2 and L4, angle α represents the included angle between L2 and L3, and angle β represents the included angle between L4 and L3.
And determining the distribution situation of the positions of the human heat sources according to the position relations among L2, L4, L1, L3 and L5 and the size relations among the angles α and β, further deducing the installation position of the air conditioner, and obtaining a second class of interruption results.
A table showing the relationship between the second type of interruption results obtained from the distribution of human body heat sources and the installation positions of air conditioners is shown in Table 2:
TABLE 2
