[0050] Example 1

[0051] This embodiment provides a control method for a patio-type air conditioner. Figure 1 FIG. 1 is a schematic structural diagram of a patio-type air conditioner according to an embodiment of the present invention. Figure 1As shown, the ceiling air conditioner includes a panel 1 and a plurality of air outlets that are rotationally symmetrical about the center O of the panel. In this embodiment, the ceiling air conditioner includes four air outlets, corresponding to four air outlet areas A, B, C, and D, respectively. Each air outlet is provided with a wind sweep baffle 2, and the wind sweep angle is controlled by the angle of the wind sweep baffle 2. The ceiling air conditioner is also provided with a sensor 10, which is an infrared sensor for detecting the coordinate data of the human body heat source. Figure 2 FIG. 1 is a flow chart of a control method for a patio-type air conditioner according to an embodiment of the present invention. Figure 2 As shown, the method includes:

[0052] S101, obtain the coordinate data of the human body heat source in the air outlet area corresponding to the designated air outlet of the ceiling-type air conditioner, and determine the wind sweeping angle range of the designated air outlet based on the coordinate data of the human body heat source in the air outlet area corresponding to the designated air outlet; wherein the coordinate data of the human body heat source and the wind sweeping angle of the air outlet satisfy a preset mapping relationship fa.

[0053] The designated air outlet can be any air outlet of the patio air conditioner. In this embodiment, the air outlet corresponding to air outlet area A is determined as the designated air outlet. Coordinate data of a human body heat source within air outlet area A is obtained. Because the coordinate data of the human body heat source within air outlet area A and the air sweep angle of the air outlet satisfy a preset mapping relationship fa, the air sweep angle range of the designated air outlet can be obtained based on the coordinate data of the human body heat source within air outlet area A, thereby controlling the air outlet direction within air outlet area A.

[0054] S102, obtaining the coordinate data of the human body heat source in the air outlet area corresponding to any other air outlet, and transforming the coordinate data of the human body heat source in the air outlet area corresponding to any other air outlet according to the positional relationship between any other air outlet and the designated air outlet.

[0055] After executing step S101, the sensor is rotated to obtain the coordinate data of the human body heat sources in air outlet area B, air outlet area C, and air outlet area D. In specific implementation, a temperature matrix is ​​established using the heat information detected by the sensor. Since the heat emitted by the human body is higher than that emitted by other objects in the room, the coordinate data of the human body heat source can be determined in the temperature matrix.

[0056] Figure 3 FIG. 1 is a schematic diagram of a temperature matrix established based on a human body heat source according to an embodiment of the present invention, as shown in FIG. Figure 3As shown, a temperature matrix is ​​obtained by the sensor 10. The size of the matrix depends on the accuracy of the selected sensor. A temperature matrix with X rows and Y columns contains X*Y pixels. Each pixel can detect an independent temperature data. Due to the difference between the human body temperature data and the ambient temperature, the human body heat source can be identified and the coordinate data of the human body heat source in the temperature matrix can be obtained. One or more human body heat sources can be identified and the human body heat source coordinate data Xmin, Xmax, Ymin, and Ymax can be obtained. Xmin is the minimum value of the coordinate of the human body heat source in the X direction, Xmax is the maximum value of the coordinate of the human body heat source in the X direction, Ymin is the minimum value of the coordinate of the human body heat source in the Y direction, and Ymax is the maximum value of the coordinate of the human body heat source in the Y direction.

[0057] S103: determining the sweeping angle range of any remaining air outlet according to the transformed coordinate data of the human body heat source and the preset mapping relationship fa.

[0058] By performing coordinate transformation on the coordinate data of the human body heat source in the air outlet area corresponding to any other air outlet, the transformed coordinate data is obtained, and any other air outlet can share the same preset mapping relationship fa with the designated air outlet, thereby realizing the wind sweeping angle adjustment of any other air outlet.

[0059] The control method of the ceiling-type air conditioner in this embodiment obtains the coordinate data of the human body heat source in the air outlet area corresponding to the designated air outlet and any other air outlet, and transforms the coordinate data of the human body heat source in the air outlet area corresponding to any other air outlet according to the positional relationship between any other air outlet and the designated air outlet, and then determines the sweeping angles of the remaining air outlets based on the preset mapping of the coordinate data of the transformed human body heat source and the coordinate data of the human body heat source in the air outlet area of ​​the designated air outlet and the sweeping angles of the air outlet. This can achieve the same mapping relationship for all air outlets, without the need to store multiple mapping relationships, thereby avoiding occupying a large amount of chip storage resources.

[0060] According to the positional relationship between any of the remaining air outlets and the designated air outlet, the coordinate data of the human body heat source in the air outlet area corresponding to any of the remaining air outlets is transformed, including: determining the symmetric relationship between any of the remaining air outlets and the designated air outlet with respect to the sensor; determining the coordinate offset according to the above symmetric relationship; and transforming the coordinate data of the human body heat source in the air outlet area corresponding to any of the remaining air outlets according to the above coordinate offset. Specifically, determining the coordinate offset according to the symmetric relationship includes: determining the coordinate offset in a first direction according to the symmetric relationship, and determining the coordinate offset in a second direction according to the symmetric relationship. According to the coordinate offset, transforming the coordinate data of the human body heat source in the air outlet area corresponding to any of the remaining air outlets includes: adding the coordinate data of the human body heat source in the first direction in the air outlet area corresponding to the designated air outlet to the coordinate offset in the first direction, and transforming the coordinate data in the first direction; adding the coordinate data of the human body heat source in the second direction in the air outlet area corresponding to the designated air outlet to the coordinate offset in the second direction, and transforming the coordinate data in the second direction.

[0061] Since the center of the panel of the ceiling air conditioner is the return air outlet, in order to avoid blocking the return air outlet, the location of the sensor is often deviated from the center of the panel of the ceiling air conditioner, that is, the location of the sensor is not the symmetrical center of the panel of the ceiling air conditioner, as mentioned above. Figure 1 As shown in , the air outlet of the air outlet area A is axially symmetrical with the air outlet of the air outlet area C, with the axis of symmetry being a. The sensor is also located on the axis of symmetry b between the air outlet of the air outlet area C and the air outlet of the air outlet area B. At the same time, b is also the axis of symmetry between the air outlet of the air outlet area A and the air outlet of the air outlet area D.

[0062] The following takes the coordinate transformation of the air outlet area A and the air outlet area C as an example to explain this embodiment in detail. Figure 4 Schematic diagram of the principle of coordinate transformation of the air outlet area A and the air outlet area C according to an embodiment of the present invention, as shown in FIG. Figure 4 As shown, the sensor mirror image is the mirror image of the sensor about the above-mentioned symmetry axis a. According to the above-mentioned positional relationship, there is no coordinate offset between the air outlet area A and the air outlet area C in the X-axis direction. The mapping relationship fa of the air outlet area A is known. The angle α is a constant (this angle is determined by the structure during the design of the smart eye), h is a constant (the installation height of the ceiling machine), and the length L1 is a constant (determined by the size of the ceiling machine panel). L is the range of people that the sensor can detect in the air outlet area A, L = h × tanα. This coverage range will be divided into 24 equal parts because the X-axis value of the sensor temperature matrix is ​​0-23. L3 is the range of people that the sensor can detect in the air outlet area C (L3 = L, L1 + L2 = L). The coordinate offset between the air outlet area A and the air outlet area C in the Y-axis direction = L / 24 × L1. The coordinate data of the human body in the air outlet area C is transformed according to the coordinate offset in the Y-axis direction.

[0063] Similarly, through the positional relationship that the sensor is also located on the symmetry axis b between the air outlet of air outlet area C and the air outlet of air outlet area B, the coordinate offset between air outlet area B and air outlet area C can be determined, and then the coordinate offset between air outlet area B and air outlet area A can be obtained, and then the corresponding coordinate transformation can be completed; according to the symmetry axis b being the symmetry axis between the air outlet of air outlet area A and the air outlet of air outlet area D, the coordinate offset between air outlet area A and air outlet area D can also be determined, and then the corresponding coordinate transformation can be completed.

[0064] The preset mapping relationship fa reflects the correspondence between the coordinate range of the human body heat source and the sweep angle range. This relationship is pre-measured through experiments and stored in the main chip's memory space in table form. During actual execution, the sweep angle is obtained by table lookup. For example, the preset mapping relationship fa specifically states: the coordinate range of the human body heat source in the X-axis direction is 0-23, and the vertical sweep angle range of the overhead crane is 40-80°.

[0065] Therefore, the wind sweeping angle range of any other air outlet is determined based on the transformed coordinate data of the human body heat source and the preset mapping relationship fa, including: determining the coordinate interval of the human body heat source in the first direction and the coordinate interval of the human body heat source in the second direction based on the coordinate data of the human body heat source in the air outlet area corresponding to any other air outlet; determining the wind sweeping angle range of any other air outlet in the first direction based on the coordinate interval of the human body heat source in the first direction and the preset mapping relationship fa; determining the wind sweeping angle range of any other air outlet in the second direction based on the coordinate interval of the human body heat source in the second direction and the preset mapping relationship fa.

[0066] The wind sweeping angle range of any other air outlet in the first direction is determined based on the coordinate interval of the human body heat source in the first direction and the preset mapping relationship fa, including: determining the maximum wind sweeping angle of any other air outlet in the first direction based on the maximum value of the coordinate of the human body heat source in the first direction and the preset mapping relationship fa; determining the minimum wind sweeping angle of any other air outlet in the first direction based on the minimum value of the coordinate of the human body heat source in the first direction and the preset mapping relationship fa, and then obtaining the wind sweeping angle range of any other air outlet in the first direction.

[0067] For example, the minimum value of the X-axis coordinate of the human body heat source in the air outlet area A detected by the sensor is Xmin, the maximum value is Xmax, the offset of the X-axis coordinate is Xp, and the X-axis coordinate range of the human body heat source after coordinate transformation is (Xmin+Xp, Xmax+Xp). Substitute Xmin+Xp, Xmax+Xp (for example, (0, 23)) into the mapping relationship fa to obtain the corresponding upper and lower sweeping angle range of the wind baffle (for example, (40°, 80°)). The above steps can obtain the sweeping angle range when the wind baffle sweeps up and down.

[0068] The wind sweeping angle range of any other air outlet in the second direction is determined based on the coordinate interval of the human body heat source in the second direction and the preset mapping relationship fa, including: determining the maximum wind sweeping angle of any other air outlet in the second direction based on the maximum value of the coordinate of the human body heat source in the second direction and the preset mapping relationship fa; determining the minimum wind sweeping angle of any other air outlet in the second direction based on the minimum value of the coordinate of the human body heat source in the second direction and the preset mapping relationship fa, and then obtaining the wind sweeping angle range of any other air outlet in the second direction.

[0069] For example, the minimum value of the Y-axis coordinate of the human body heat source in the air outlet area A detected by the sensor is Ymin, the maximum value is Ymax, the offset of the Y-axis coordinate is Yp, and the Y-axis coordinate range of the human body heat source after coordinate transformation is (Ymin+Yp, Ymax+Yp). Substitute Ymin+Yp, Ymax+Yp (for example, (0, 23)) into the mapping relationship fa to obtain the corresponding upper and lower sweeping angle range of the wind sweeping baffle (for example, (40°, 80°)). The above steps can obtain the sweeping angle range when the wind sweeping baffle sweeps left and right.

[0070] Figure 5 FIG. 1 is a flow chart of another method for controlling a patio-type air conditioner according to an embodiment of the present invention. Figure 5 As shown, the method includes the following preferred steps:

[0071] S1, obtain the temperature matrix of the air outlet area A through the sensor.

[0075] S4, obtain the temperature matrix in the air outlet areas B, C, and D through the sensor, identify the human body heat source based on the temperature matrix in the air outlet areas B, C, and D and obtain the coordinate data of the human body heat source in the air outlet areas B, C, and D, determine the offset of the X-axis and Y-axis based on the positional relationship between the air outlets in the air outlet areas B, C, and D and the air outlet in the air outlet area A, and then perform coordinate transformation on the coordinate data of the above-mentioned human body heat source.

[0076] S5 , calculating the sweeping angle range of the air outlet in the air outlet areas B, C, and D according to the coordinate data of the human body heat source in the air outlet areas B, C, and D after coordinate transformation and the preset mapping relationship fa.

[0077] Using the control method proposed in this paper, it is only necessary to store the preset mapping relationship fa between the coordinate data of the human body heat source in the air outlet area A and the wind sweeping angle in the main control chip of the indoor unit of the ceiling-type air conditioner to control the wind sweeping angle of each air outlet area, which greatly reduces the storage space of the chip and helps to reduce costs.
