The human body sensor is a sensor with an infrared receiving matrix as a receiving device, can detect the position of a human body according to an infrared reflection principle, is used for identifying the number and the position of the human body in a measurable area, can scan infrared sources in the measurable area according to a row-column mode, and outputs position information corresponding to the detected infrared sources in the row-column mode. From this position information, the position of the infrared source relative to the human detection sensor can be determined. The motion detection sensor can be generally applied to home appliances such as an air conditioner.
The air deflector is a guide plate positioned at an air outlet of an indoor unit of the air conditioner, and the aim of changing the wind direction can be achieved by controlling and adjusting the angle of the air deflector.
For the indoor unit of the air conditioner with air out from four sides, the human detection sensor is usually installed on the corner of the indoor unit of the air conditioner, namely, in the included angle range between two adjacent air deflectors, one position can be arbitrarily selected to be installed on four corners of the indoor unit of the air conditioner. When the human detection sensor is arranged on different corners of the indoor unit of the air conditioner, the corresponding control logics of the air deflector are different. Therefore, the installation position of the human detection sensor influences the control of the air deflector by the indoor unit of the air conditioner.
Since the indoor unit of the air conditioner may encounter a problem of uncertainty of the installation position during the installation process, the installation position of the human detecting sensor also has uncertainty. The position of the air deflector can be determined in the design stage of the indoor unit of the air conditioner, and cannot be changed due to different installation positions.
In order to improve the use experience of the air conditioner, the angle of the air deflector in the corresponding area can be controlled by detecting the position of a human body. For example, to realize the function of the wind moving along with the human movement, the detected wind deflector above the human body is adjusted to a first preset wind outlet angle, so that the first preset wind outlet angle just faces the human body; if the function that the wind avoids the human body is to be realized, the detected air deflector above the human body is adjusted to the second preset air outlet angle, and the wind blown out from the air outlet is prevented from directly facing the human body.
It is necessary to input the position information of the human detecting sensor to the control unit of the air conditioner or to cause the control unit of the air conditioner to automatically acquire the position information of the human detecting sensor after the installation of the indoor unit of the air conditioner is completed.
The position information of the human sensor can be determined by adjusting the dial switch, but the mode not only involves the error risk brought by manual operation, but also needs to ascend and open the decoration when the dial switch is operated, and the operation is inconvenient.
The setting can also be done through the settings menu of the line controller, but this also involves the risk of errors due to manual operation. And the shapes of the indoor units of different air conditioners are different, and the premise of manual operation is that the products are well known, so the use difficulty is increased.
An embodiment of the present application provides a method for determining a position of an infrared sensor, which is applied to an air conditioner indoor unit, and an execution subject of the method is a control unit (e.g., a processor) of the air conditioner indoor unit, and with reference to fig. 1, the method may include S101-S102:
s101, determining first position information between the infrared sensor and each infrared source device in the plurality of infrared source devices.
The infrared sensor is a measuring system using infrared rays as a medium, and in the embodiment of the application, the infrared sensor can be a human body sensor. The infrared source device is a device which is installed on an air deflector of an air conditioner indoor unit and can emit infrared light waves, for example, the infrared source device can be an infrared Light Emitting Diode (LED) lamp bead, and the infrared LED lamp bead is one of infrared LED lamps and can emit infrared light waves when being in an open state.
In one possible implementation, each infrared source device is installed at the center of the air deflector where the infrared source device is located. The infrared sensor is arranged on the corner between any two air deflectors of the indoor unit of the air conditioner.
The first position information refers to relative position information between the infrared sensor and each of the plurality of infrared source devices. The infrared sensor may determine first position information between the infrared sensor and each infrared source device based on infrared light waves emitted by each infrared source device.
Referring to fig. 2, taking an air conditioner with four air outlets as an example, the air conditioner includes four air deflectors, which are respectively an air deflector 1, an air deflector 2, an air deflector 3, and an air deflector 4. The corner between the air deflector 4 and the air deflector 1 is the position A, the corner between the air deflector 1 and the air deflector 2 is the position B, the corner between the air deflector 2 and the air deflector 3 is the position C, the corner between the air deflector 3 and the air deflector 4 is the position D, and the infrared sensor can be installed at any one of the position A, the position B, the position C and the position D.
S102, determining the position information of the infrared sensors according to the first position information between the infrared sensors and each infrared source device.
The position of the air deflector is fixed, and the position of each infrared source device arranged on the air deflector is also fixed. When the infrared sensors are arranged at different positions, the relative positions of the infrared sensors and the air guide plate 1, the air guide plate 2, the air guide plate 3 and the air guide plate 4 can be changed, and the first position information of the infrared source devices arranged on the air guide plate can be different, so that the position information of the infrared sensors can be reversely deduced according to the first position information between the infrared sensors and each infrared source device. The position information of the infrared sensor is used for determining the position of the infrared sensor between any two air deflectors.
The embodiment of the application provides a method for determining the position of an infrared sensor, which can determine first position information between the infrared sensor and each infrared source device, and because the first position information is relative position information between the infrared sensor and each infrared source device, when the position of each infrared source device is known, the infrared sensor can be further determined to be positioned in an included angle range formed by two air deflectors in a plurality of air deflectors according to the first position information. The whole process does not need manual interference, so that the labor cost is saved, and the risk of misoperation is avoided.
In one possible implementation, before determining the first positional information between the infrared sensor and each of the plurality of infrared source devices, the method further comprises:
and S103, sequentially starting each infrared source device.
When any infrared source device in the infrared source devices is in an opening state, the rest infrared source devices except the infrared source device are in a closing state.
Exemplarily, an infrared source device installed at the center of the air deflector 1 is an infrared LED lamp bead 1, an infrared source device installed at the center of the air deflector 2 is an infrared LED lamp bead 2, an infrared source device installed at the center of the air deflector 3 is an infrared LED lamp bead 3, and an infrared source device installed at the center of the air deflector 4 is an infrared LED lamp bead 4. When the infrared LED lamp bead 1 is in an on state, the infrared LED lamp bead 2, the infrared LED lamp bead 3 and the infrared LED lamp bead 4 are in an off state.
It should be noted that the infrared source device is installed in the center of the air deflector, so that the position information of the infrared sensor can be determined according to the first position information between the infrared sensor and each infrared source device. The installation position of the infrared source device is only exemplarily illustrated in the embodiments of the present application, and thus, the installation position of the infrared source device should not be construed as being limited.
For example, referring to fig. 3, the method for sequentially turning on the infrared LED lamp beads by the control unit of the air conditioner indoor unit may include S1031 to S1035:
and S1031, the control unit controls the infrared LED lamp beads 1 to be turned on, so that the infrared LED lamp beads 1 start to emit infrared light waves. At this time, the LED lamp beads 2, 3 and 4 are in an off state.
So alright in order to determine the first positional information between infrared sensor and infrared LED lamp pearl 1.
S1032, the control unit controls the infrared LED lamp beads 1 to be closed so that the infrared LED lamp beads 1 stop emitting infrared light waves, and controls the infrared LED lamp beads 2 to be opened so that the infrared LED lamp beads 2 start emitting infrared light waves.
At this time, the LED lamp beads 1, 3, and 4 are in an off state.
So alright in order to determine the first positional information between infrared sensor and infrared LED lamp pearl 2.
S1033, the control unit controls the infrared LED lamp beads 2 to be closed so that the infrared LED lamp beads 2 stop emitting infrared light waves, and controls the infrared LED lamp beads 3 to be opened so that the infrared LED lamp beads 3 start emitting infrared light waves.
At this time, the LED lamp beads 1, 2 and 4 are in an off state.
So alright in order to determine the first positional information between infrared sensor and infrared LED lamp pearl 3.
S1034 and the control unit controls the infrared LED lamp beads 3 to be closed so that the infrared LED lamp beads 3 stop emitting infrared light waves, and controls the infrared LED lamp beads 4 to be opened so that the infrared LED lamp beads 4 start emitting infrared light waves.
At this time, the LED lamp beads 1, 2 and 3 are in an off state.
So that the first position information between the infrared sensor and the infrared LED lamp bead 4 can be determined.
And S1035, the control unit controls the infrared LED lamp beads 4 to be closed, so that the infrared LED lamp beads 4 stop emitting infrared light waves.
It should be noted that, in the embodiment of the present application, the turn-on sequence of the infrared LED lamp bead 1, the infrared LED lamp bead 2, the infrared LED lamp bead 3, and the infrared LED lamp bead 4 is not limited, as long as it is satisfied that the turn-on sequence is one by one.
In one possible implementation manner, a specific implementation manner of S101 includes:
referring to fig. 4, an infrared source device in an on state among a plurality of infrared source devices is determined, and first position information between an infrared sensor and the infrared source device in the on state is determined. The first location information may include location information P1, location information P2, location information P3, and location information P4.
The first position information between the infrared sensor and the infrared LED lamp bead 1 may be position information P1, the first position information between the infrared sensor and the infrared LED lamp bead 2 may be position information P2, the first position information between the infrared sensor and the infrared LED lamp bead 3 may be position information P3, and the first position information between the infrared sensor and the infrared LED lamp bead 4 may be position information P4.
Specifically, when the infrared LED lamp bead 1 emits infrared light waves, the position information P1 of the infrared LED lamp bead 1 detected by the infrared sensor receiving matrix is read; when the infrared LED lamp beads 2 emit infrared light waves, reading position information P2 of the infrared LED lamp beads 2 detected by the infrared sensor receiving matrix; when the infrared LED lamp beads 3 emit infrared light waves, reading position information P3 of the infrared LED lamp beads 3 detected by the infrared sensor receiving matrix; when the infrared LED lamp beads 4 emit infrared light waves, the position information P4 of the infrared LED lamp beads 4 detected by the infrared sensor receiving matrix is read.
It should be noted that, because the positions of the air deflectors of the indoor unit of the air conditioner are determined, when only the position information of the infrared source device on any one air deflector is determined, the position information of the infrared source devices on other air deflectors can be determined, so the embodiment of the application does not limit the number of the infrared source devices, the infrared source device can be installed on any one air deflector, and the infrared source device can also be installed on each air deflector.
Referring to fig. 5, in one possible implementation, a specific implementation of S102 includes S1021-S1022:
and S1021, determining the area identifier of each first position information in the maximum detection range of the infrared sensor according to the first position information between the infrared sensor and each infrared source device.
Specifically, N regions included in the maximum detection range of the infrared sensor are determined, where the N regions are obtained by dividing a region formed by the leftmost detection range and the rightmost detection range of the infrared sensor, and N is an integer greater than or equal to 1.
The area of each region may be divided equally, each region may have a region identifier, and the region identifiers of the N regions may sequentially increase or decrease in a preset order. The preset order may be a direction in which the leftmost detection range of the infrared sensor points to the rightmost detection range. Or the preset order may be a direction in which the rightmost detection range of the infrared sensor points to the leftmost detection range.
With continued reference to fig. 4, for example, the area identifications of the N areas increase in order in a direction from the leftmost detection range of the infrared sensor toward the rightmost detection range. When N is 6, the region identifications from the N regions are S1, S2, S3, S4, S5, S6 in order. Wherein S1> S2> S3> S4> S5> S6.
After the area identifier of the N areas is determined, the area identifier of each first position information in the N areas may be determined according to the first position information between the infrared sensor and each infrared source device. The first position information is the first position information between the infrared sensor and each corresponding infrared source device.
Optionally, the area identifier where the first position information between the infrared sensor and each infrared source device is located in the N areas may be determined by determining the coordinate information of the first position information corresponding to each infrared source device in the N areas.
For example, when the coordinate information of the infrared source device 1 falls within the area identified as S1, the area identified as S1, where the first position information between the infrared sensor and the infrared source device 1 is located among the N areas. When the coordinate information of the infrared source device 1 falls within the area identified as S3, the area identified as S3 where the first position information between the infrared sensor and the infrared source device 1 is located among the N areas.
With continued reference to fig. 4, where 4-1 in fig. 4 indicates that the area in which the position information P1 is located among 6 areas is identified as S2, the area in which the position information P2 is located among 6 areas is identified as S3, the area in which the position information P3 is located among 6 areas is identified as S4, and the area in which the position information P4 is located among 6 areas is identified as S5.
4-2 in FIG. 4 indicates that the area where the position information P1 is located among 6 areas is identified as S5, the area where the position information P2 is located among 6 areas is identified as S2, the area where the position information P3 is located among 6 areas is identified as S3, and the area where the position information P4 is located among 6 areas is identified as S4.
4-3 in FIG. 4 indicates that the area where the position information P1 is located among 6 areas is identified as S3, the area where the position information P2 is located among 6 areas is identified as S4, the area where the position information P3 is located among 6 areas is identified as S5, and the area where the position information P4 is located among 6 areas is identified as S2.
4-4 in FIG. 4 indicates that the area where the position information P1 is located among 6 areas is identified as S4, the area where the position information P2 is located among 6 areas is identified as S5, the area where the position information P3 is located among 6 areas is identified as S2, and the area where the position information P4 is located among 6 areas is identified as S3.
And S1022, determining the position information of the infrared sensor according to the relation between the area identifications of the first position information in the maximum detection range of the infrared sensor.
With continued reference to fig. 4, the positions of the infrared sensors may include an a position, a B position, a C position, and a D position. The included angle between the air deflector 4 and the air deflector 1 can be defined as the position A, the included angle between the air deflector 1 and the air deflector 2 can be defined as the position B, the included angle between the air deflector 2 and the air deflector 3 can be defined as the position C, and the included angle between the air deflector 3 and the air deflector 4 can be defined as the position D.
By determining a first infrared source device corresponding to the first position information with the largest zone identifier and a second infrared source device corresponding to the first position information with the smallest zone identifier in the plurality of infrared source devices, the position information of the infrared sensor can be determined to be in the range of an included angle between the air deflector where the first infrared source device is located and the air deflector where the second infrared source device is located.
For example, in 4-1 in fig. 4, the area where the position information P1 is located is identified as S2, the area where the position information P2 is located is identified as S3, the area where the position information P3 is located is identified as S4, and the area where the position information P4 is located is identified as S5.
The first position information with the largest region identification, namely position information P4, the corresponding infrared source device is an infrared LED lamp bead 4, the first position information with the smallest region identification, namely position information P1, the corresponding infrared source device is an infrared LED lamp bead 1. Therefore, the position information of the infrared sensor is in the range of the included angle between the air deflector 4 where the infrared LED lamp beads 4 are located and the air deflector 4 where the infrared LED lamp beads 1 are located. The position of the infrared sensor can be further determined to be the A position according to the position information of the infrared sensor.
The method for determining the position of the infrared sensor as the position B, the position C and the position D may refer to the above-mentioned method step for determining the position of the infrared sensor as the position a, and is not described herein again.
In a possible implementation manner, when the area identifiers of the first position information between the infrared sensor and the two or more infrared source devices in the N areas are the same, which indicates that the number of the divided areas is too small, the maximum detection range of the infrared sensor can be divided into M areas, where M is greater than N. Then, according to the first position information between the infrared sensor and each infrared source device, the zone identifier where the first position information between the infrared sensor and each infrared source device is located in M zones is determined, and S1022 is executed again.
For example, when N is 6, M may be 12, 24, etc. which is a larger number than N, and when M is 12, the original 6 regions may be subdivided into 12 regions, and if there is still the same region identifier, the value of M is continuously increased until the infrared sensor is no longer the same as the region identifier where the first position information between two or more infrared source devices is located in the M regions. If there is no case where the zone identifications are the same, determining a zone identification where each of the first position information is located in the newly divided 12 zones according to the first position information between the infrared sensor and each of the infrared source devices, and re-executing S1022.
In one possible implementation, the method further includes:
and S104, if the first position information between the infrared sensor and each infrared source device does not meet the preset relationship, sending alarm information.
The alarm information is used for indicating the position installation error of the air deflector or that at least one infrared source device falls off from the corresponding air deflector.
Referring to fig. 4, the preset relationship is an arrangement of the first position information of the infrared sensor and each infrared source device according to the size of the area identifier where the first position information is located. The preset relationship includes:
when the position of the infrared sensor is the A position, the preset relationship is as follows: region identifier S5 corresponding to position information P4 > region identifier S4 corresponding to position information P3 > region identifier S3 corresponding to position information P2 > region identifier S2 corresponding to position information P1.
When the position of the infrared sensor is the position B, the preset relationship is as follows: region identifier S5 corresponding to position information P1 > region identifier S4 corresponding to position information P4 > region identifier S3 corresponding to position information P3 > region identifier S2 corresponding to position information P2.
When the position of the infrared sensor is the position C, the preset relationship is as follows: region identifier S5 corresponding to position information P3 > region identifier S4 corresponding to position information P2 > region identifier S3 corresponding to position information P1 > region identifier S2 corresponding to position information P4.
When the position of the infrared sensor is the D position, the preset relationship is as follows: region identifier S5 corresponding to position information P2 > region identifier S4 corresponding to position information P1 > region identifier S3 corresponding to position information P4 > region identifier S2 corresponding to position information P3.
In the embodiment of the application, if the arrangement sequence corresponding to the first position information of the plurality of infrared source devices does not satisfy the four conditions, it indicates that the position of the air deflector is installed incorrectly or at least one infrared source device falls off from the corresponding air deflector.
Illustratively, referring to fig. 6, when the position of the infrared sensor is the B position, the first position information of the plurality of infrared source devices is arranged in the following order: region identifier S5 corresponding to position information P2 > region identifier S4 corresponding to position information P4 > region identifier S3 corresponding to position information P3 > region identifier S2 corresponding to position information P1. Due to the fact that the preset relation is not met, the fact that the installation sequence of the air guide plate 3 where the infrared LED lamp beads 3 corresponding to the position information P3 are located and the installation sequence of the air guide plate 4 where the infrared LED lamp beads 4 corresponding to the position information P4 are located are wrong can be obtained.
