[0020] Optionally, the step of calculating the first horizontal distance between the first location and the signal receiving location of the air conditioner includes:

[0021] The first horizontal distance is calculated using the first distance and the longitudinal distance between the first position and the signal receiving position of the air conditioner.

[0022] Optionally, the longitudinal distance between the first position and the signal receiving position of the air conditioner is obtained by subtracting the height of the first position from the height of the signal receiving position of the air conditioner. The height of the first position is obtained by the remote control emitting infrared light from the first position to the ground.

[0023] Optionally, the step of calculating the relative horizontal distance between the first and second positions includes:

[0024] Detect whether the relative height value between the first position and the second position is greater than the preset height value;

[0028] Optionally, the step of calculating the actual distance between the first and second positions includes:

[0029] Obtain the preset instruction information;

[0030] The horizontal distance between the first and second positions is calculated based on the actual distance and the relative height between the first and second positions.

[0031] In another aspect of the invention, an air conditioning system is also provided, comprising:

[0032] An air conditioner and a remote control, wherein the air conditioner is equipped with a controller, the controller including a memory and a processor, wherein the memory stores a machine-executable program, and when the machine-executable program is executed by the processor, it implements a distance measurement method based on the air conditioner system according to any of the above.

[0033] The distance measurement method based on an air conditioner system of the present invention obtains a first feedback signal from a remote control at a first position, and calculates a first distance between the first position and the signal receiving position of the air conditioner based on the first feedback signal. Then, it obtains a second feedback signal from the remote control at a second position, and calculates a second distance between the second position and the signal receiving position of the air conditioner based on the second feedback signal. Finally, it calculates the distance between the first and second positions based on the first and second distances. In other words, by utilizing the cooperation between the air conditioner and the remote control, the approximate distance between two positions can be obtained, enabling the air conditioner system to measure the distance between two positions. Therefore, users can use the air conditioner system to measure the distance between two positions indoors, thus facilitating a better understanding of the indoor space and providing general reference information when placing furniture or measuring the dimensions of certain furniture. In short, by adding a distance measurement function to the air conditioner system, it provides users with a richer user experience and improves the convenience of their lives.

[0034] Furthermore, the distance measurement method based on the air conditioner system of the present invention obtains the actual angle between the first position and the second position relative to the signal receiving position of the air conditioner, and obtains the lateral angle between the first position and the second position relative to the signal receiving position of the air conditioner. It then detects whether the lateral angle is greater than a preset threshold. If so, it calculates the actual distance between the first position and the second position; otherwise, it calculates the relative horizontal distance between the first position and the second position. Specifically, it determines which two positions the user actually wants to measure based on the positional relationship between the first position and the second position relative to the air conditioner. If the lateral angle is less than or equal to a preset threshold, it determines the distance between two positions on the straight line where the projection of the signal line at the first position on the same lateral plane lies. Therefore, selecting the calculation method based on the lateral angle helps to obtain more accurate distance results.

[0045] Those skilled in the art should understand that the embodiments described below are merely a part of the embodiments of the present invention, and not all of the embodiments of the present invention. These partial embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0046] It should be noted that the logic and / or steps represented in the flowchart or otherwise described herein, for example, can be considered as a sequenced list of executable instructions for implementing logical functions, and can be specifically implemented in any computer-readable medium for use by, or in conjunction with, an instruction execution system, apparatus or device (such as a computer-based system, a processor-included system or other system that can fetch and execute instructions from, an instruction execution system, apparatus or device).

[0047] like Figure 1 and Figure 2 As shown, the air conditioning system 10 includes an air conditioner 110 and a remote controller 120. The air conditioner 110 is equipped with an infrared radar, and the remote controller 120 is equipped with an infrared transmitter. The air conditioner 110 is equipped with a controller 200, which includes a memory 210 and a processor 220. The memory 210 stores a machine-executable program 211, which, when executed by the processor 220, implements the ranging method based on the air conditioning system in any of the following embodiments.

[0048] like Figure 3 As shown, in one embodiment, the ranging method based on an air conditioning system generally includes:

[0049] Step S101: Obtain the first feedback signal from the remote control at the first position. Specifically, at the first of two positions where distance needs to be measured, the remote control transmits an infrared signal to the air conditioner. The air conditioner's infrared radar receives the infrared signal from the remote control, causing the controller to obtain the first feedback signal.

[0050] Step S102: Obtain the first distance between the first position and the signal receiving position of the air conditioner based on the first feedback signal. Specifically, obtain the distance between the infrared signal transmitting position and the receiving position, which is the distance between the remote control position and the air conditioner's signal receiving position. (Refer to...) Figure 4 and Figure 5 As shown in the figure, the first distance L1 between the first position of the remote control 120 and the signal receiving position of the air conditioner 110 is obtained.

[0051] Step S103: Obtain the second feedback signal from the remote control at the second position. Specifically, at the second of the two positions where distance needs to be measured, the remote control emits an infrared signal towards the air conditioner. The air conditioner's infrared radar receives the infrared signal from the remote control, enabling the controller to obtain the second feedback signal.

[0052] Step S104: Obtain the second distance between the second position and the signal receiving position of the air conditioner based on the second feedback signal. (Refer to...) Figure 4 and Figure 5As shown in the figure, the second distance L2 between the second position of the remote controller 120 and the signal receiving position of the air conditioner 110 is obtained.

[0053] Step S105: Calculate the distance between the first position and the second position based on the first distance and the second distance.

[0054] Reference Figure 6 As shown, in one embodiment, this step includes:

[0055] Step S201: Obtain the actual angle between the first position and the second position relative to the signal receiving position of the air conditioner. Specifically, this means obtaining the angle between the two incident light paths based on the infrared transmission lines of the remote control from the first position to the signal receiving position of the air conditioner and the infrared transmission lines of the remote control from the second position to the signal receiving position of the air conditioner.

[0056] Step S202: Obtain the lateral angle between the first position and the second position relative to the signal receiving position of the air conditioner. Specifically, this means obtaining the angle between the projections of the infrared transmission lines of the remote control from the first position to the signal receiving position of the air conditioner and the infrared transmission lines of the remote control from the second position to the signal receiving position of the air conditioner on the same lateral plane.

[0057] Step S203: Detect whether the lateral angle is greater than a preset threshold. If yes, proceed to step S204; otherwise, proceed to step S205. Specifically, the preset threshold can be any value less than or equal to 5 degrees, such as 1 degree or 3 degrees.

[0058] Step S204: Calculate the actual distance between the first position and the second position. If the lateral angle between the first position and the second position relative to the signal receiving position of the air conditioner is greater than a preset threshold, then calculate the actual distance between the first position and the second position.

[0059] Specifically, the first distance, the second distance, and the actual included angle are substituted into the cosine theorem formula to calculate the actual distance between the first and second positions. (Refer to...) Figure 5 As shown, the first distance is L1, the second distance is L2, and the actual included angle is α. The distance between the first and second positions, together with the first and second distances, form a triangle. Therefore, the distance between the first and second positions can be calculated using the law of cosines.

[0060] Step S205: Calculate the relative horizontal distance between the first position and the second position. The relative horizontal distance is the distance along the projection direction of the first position and the second position onto the same horizontal plane, extending from the projection of the remote control's signal line at the first position onto that horizontal plane.

[0061] In actual use, although sometimes the first and second positions to be measured should theoretically be located on the same horizontal plane, and the projection of the line connecting the first and second positions to the signal receiving position of the air conditioner on the horizontal plane should be on the straight line where the projection of the signal line of the first position is on the horizontal plane, due to the existence of actual operation errors, the projection of the line connecting the first and second positions to the signal receiving position of the air conditioner on the same horizontal plane may not be on the straight line.

[0062] However, if the lateral angle between the first position and the second position relative to the signal receiving position of the air conditioner is less than or equal to a preset threshold, it means that the projections of the infrared transmission lines of the remote control from the first position to the signal receiving position of the air conditioner and the infrared transmission lines of the remote control from the second position to the signal receiving position of the air conditioner onto the same lateral plane are close to the straight line where the projection of the signal line at the first position lies on that lateral plane. Therefore, it is determined that the user actually wants to measure the distance between two positions located on the same lateral plane, where the projection of the signal line at the first position lies on the straight line where the projection of the signal line at the first position lies on that lateral plane. This determines that the relative horizontal distance between the first position and the second position needs to be calculated.

[0063] Specifically, calculate the first horizontal distance between the first position and the signal receiving position of the air conditioner; calculate the second horizontal distance between the second position and the signal receiving position of the air conditioner; and obtain the horizontal distance between the first position and the second position by subtracting the first horizontal distance from the second horizontal distance.

[0064] Specifically, the first horizontal distance is calculated using the first distance and the longitudinal distance between the first position and the signal receiving position of the air conditioner. In other words, the first horizontal distance is calculated using the Pythagorean theorem, specifically by using the right triangle formed by the first distance, the longitudinal distance between the first position and the signal receiving position of the air conditioner, and the first horizontal distance.

[0065] The longitudinal distance between the first position and the air conditioner's signal receiving position is obtained by subtracting the height of the first position from the height of the air conditioner's signal receiving position. The height of the first position is obtained by the remote control emitting infrared light from the first position to the ground. Specifically, the height of the air conditioner's signal receiving position is pre-stored in the program after the air conditioner is installed.

[0066] The remote control has an infrared transmitter and an infrared receiver, so that by emitting infrared light towards the ground from a first position, the altitude of that first position can be obtained. The altitude of the first position is then transmitted to the air conditioner. Therefore, the step of obtaining the first feedback signal from the remote control at the first position also includes: obtaining the altitude information of the first position.

[0067] Similarly, the step of calculating the second horizontal distance between the second position and the signal receiving position of the air conditioner includes: calculating the second horizontal distance using the second distance and the longitudinal distance between the second position and the signal receiving position of the air conditioner. The specific method is described above. Therefore, the step of obtaining the second feedback signal from the remote control at the second position also includes: obtaining the height information of the second position.

[0068] Reference Figure 4 As shown, L1 represents the first distance, and H1 represents the longitudinal distance between the first position and the signal receiving position of the air conditioner. Substituting L1 into the hypotenuse of the right triangle and H1 into one leg of the right triangle, the first horizontal distance, which serves as the other leg, can be calculated using the Pythagorean theorem. Similarly, L2 represents the second distance, and H2 represents the longitudinal distance between the second position and the signal receiving position of the air conditioner. Substituting L2 into the hypotenuse of the right triangle and H2 into one leg of the right triangle, the second horizontal distance, which serves as the other leg, can be calculated using the Pythagorean theorem. Subtracting the first horizontal distance from the second horizontal distance gives the horizontal distance between the first and second positions.

[0069] It should be noted that the horizontal distance between the first position and the second position is obtained by subtracting the first horizontal distance from the second horizontal distance, which is to subtract the smaller value from the larger value of the first horizontal distance and the second horizontal distance.

[0070] In this embodiment, a first feedback signal from the remote control at a first position is acquired, and a first distance between the first position and the signal receiving position of the air conditioner is obtained based on the first feedback signal. A second feedback signal from the remote control at a second position is acquired, and a second distance between the second position and the signal receiving position of the air conditioner is obtained based on the second feedback signal. The distance between the first and second positions is then calculated based on the first and second distances. In other words, by utilizing the cooperation between the air conditioner and the remote control, the distance between the two positions can be approximated, enabling the air conditioner system to measure the distance between two positions.

[0071] Therefore, this allows users to measure the distance between two locations within a room using the air conditioning system, enabling them to better understand the indoor space and providing general reference information when placing furniture or measuring the dimensions of certain appliances. In short, by adding distance measurement functionality to the air conditioning system, it enriches the user experience and improves the convenience of daily life.

[0072] Furthermore, by obtaining the actual angle between the first position and the second position relative to the signal receiving position of the air conditioner, and obtaining the lateral angle between the first position and the second position relative to the signal receiving position of the air conditioner, it is detected whether the lateral angle is greater than a preset threshold. If so, the actual distance between the first position and the second position is calculated; if not, the relative horizontal distance between the first position and the second position is calculated.

[0073] Specifically, this involves determining which two locations the user actually wants to measure based on the positional relationship between the first and second positions relative to the air conditioner. Then, it checks if the lateral angle is less than or equal to a preset threshold. This determines the distance between two locations on the straight line where the projection of the signal line at the first position on the same lateral plane lies. Therefore, selecting the calculation method based on the lateral angle helps obtain more accurate distance results.

[0074] like Figure 7 As shown, in one embodiment, the step of calculating the relative horizontal distance between the first position and the second position includes:

[0075] Detect whether the relative height value between the first position and the second position is greater than a preset height value; if it is less than or equal to the preset height value, perform the step of calculating the relative horizontal distance between the first position and the second position; if it is greater than the preset height value, perform the step of calculating the actual distance between the first position and the second position.

[0076] In this embodiment, the ranging method based on the air conditioner system generally includes:

[0077] Step S301: Obtain the first feedback signal from the remote control at the first position.

[0078] Step S302: Obtain the first distance between the first position and the signal receiving position of the air conditioner based on the first feedback signal.

[0079] Step S303: Obtain the second feedback signal from the remote control at the second position.

[0080] Step S304: Obtain the second distance between the second position and the signal receiving position of the air conditioner based on the second feedback signal.

[0081] Step S305: Obtain the actual angle between the first position and the second position relative to the signal receiving position of the air conditioner.

[0082] Step S306: Obtain the lateral angle between the first position and the second position relative to the signal receiving position of the air conditioner.

[0083] Step S307: Detect whether the horizontal included angle is greater than the preset threshold. If yes, proceed to step S308; otherwise, proceed to step S309.

[0084] Step S308: Calculate the actual distance between the first position and the second position.

[0085] Step S309: Detect whether the relative height value between the first position and the second position is greater than a preset height value. If yes, proceed to step S308; otherwise, proceed to step S310. Specifically, the relative height value between the first position and the second position is the distance between the two projected positions after the first position and the second position are projected onto the same longitudinal line. The preset height value can be any value less than or equal to 5 cm, such as 3 cm, 4 cm, 5 cm, etc. If the relative height value between the first position and the second position exceeds the preset height value, even if the lateral angle between the first position and the second position relative to the signal receiving position of the air conditioner is greater than a preset threshold, it indicates that the user actually wants to measure the actual distance between the first position and the second position.

[0086] Theoretically, the first and second positions that the user wants to measure should be located on the same horizontal plane, and the projection of the line connecting the first and second positions to the air conditioner's signal receiving position onto this horizontal plane should lie on the straight line where the projection of the signal line at the first position lies. However, due to actual operational errors, it is possible that the projection of the line connecting the first and second positions to the air conditioner's signal receiving position onto this horizontal plane is not on the straight line, and the first and second positions are not even on the same horizontal plane.

[0087] After detecting the lateral angle, the relative height values ​​of the first and second positions are measured. If the relative height value is less than or equal to a preset height value, it is determined that the user wants to measure the distance between two positions located on the same lateral plane, and the relative horizontal distance between the first and second positions is calculated. If the relative height value is greater than the preset height value, it is determined that the user wants to measure the distance between two positions not located on the same lateral plane, and the actual distance between the first and second positions is calculated.

[0088] Step S310: Calculate the relative horizontal distance between the first position and the second position.

[0089] In this embodiment, before calculating the relative horizontal distance between the first and second positions, the relative height value of the first and second positions is checked to see if it is greater than a preset height value. If the relative height value is less than or equal to the preset height value, the relative horizontal distance between the first and second positions is calculated. If the relative height value is greater than the preset height value, the actual distance between the first and second positions is calculated. This allows for better identification of whether the distance the user actually wants to measure is the distance between two positions on the straight line where the projection of a signal line located at the first position on the same horizontal plane lies, thus obtaining a more accurate distance result.

[0090] like Figure 8 As shown, in one embodiment, after the step of calculating the actual distance between the first position and the second position, the method includes: obtaining preset indication information; and calculating the horizontal distance between the first position and the second position based on the actual distance and the relative height between the first position and the second position.

[0091] In this embodiment, the ranging method based on the air conditioner system generally includes:

[0092] Step S401: Obtain the first feedback signal from the remote control at the first position.

[0093] Step S402: Obtain the first distance between the first position and the signal receiving position of the air conditioner based on the first feedback signal.

[0094] Step S403: Obtain the second feedback signal from the remote control at the second position.

[0095] Step S404: Obtain the second distance between the second position and the signal receiving position of the air conditioner based on the second feedback signal.

[0096] Step S405: Obtain the actual angle between the first position and the second position relative to the signal receiving position of the air conditioner.

[0097] Step S406: Obtain the lateral angle between the first position and the second position relative to the signal receiving position of the air conditioner.

[0098] Step S407: Detect whether the horizontal included angle is greater than the preset threshold. If yes, proceed to step S408; otherwise, proceed to step S411.

[0099] Step S408: Calculate the actual distance between the first position and the second position.

[0100] Step S409: Obtain preset instruction information. Specifically, this could be instruction information sent by the remote control.

[0101] Step S410: Calculate the horizontal distance between the first and second positions based on the actual distance and the relative height between the first and second positions. Specifically, the actual distance, the relative height between the first and second positions, and the calculation of the horizontal distance between the first and second positions form a right triangle, thus obtaining the actual distance. The relative height between the first and second positions can be obtained by subtracting the distance of the first position relative to the ground from the distance of the second position relative to the ground. Therefore, the horizontal distance between the first and second positions can be obtained using the Pythagorean theorem.

[0102] Therefore, after obtaining the actual distance between the first and second positions, the horizontal distance between the first and second positions can be calculated according to the user's needs.

[0103] Step S411: Calculate the relative horizontal distance between the first position and the second position.

[0104] In this embodiment, after calculating the actual distance between the first and second positions and obtaining preset indication information, the horizontal distance between the first and second positions is calculated based on the actual distance and the relative height between them. Therefore, after obtaining the actual distance between the first and second positions, the horizontal distance can be calculated according to the user's needs, making distance measurement more flexible.

[0105] It should be noted that, in any of the above embodiments, after obtaining the distance between the first position and the second position, it can be output by voice, displayed on the remote control screen, displayed on the air conditioner screen, etc.

[0106] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
