Detailed Description
Preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present application, and are not intended to limit the scope of the present application.
In the description of the present application, a "controller" may include hardware, software, or a combination of both. Accordingly, the method of the present application may be implemented in software or a combination of software and hardware. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, the indoor unit control method of an air conditioner of the present application includes an intelligent control mode, which mainly includes the steps of:
s11, acquiring the height H, the movement speed V and the distance S relative to the indoor unit of the target object.
The target objects are mainly users, and the users are divided according to ages, and mainly comprise children, adults and old people. The target object is of course not limited to the aforementioned type but may include pets living in a room where the indoor unit is installed, or the like, and in short, the target object is living in a room where the indoor unit is installed and has a sense of change in the temperature of the room or the like, and may transmit such sense in some form.
The application can detect the height, the movement speed and the distance relative to the indoor unit of the target object by the detection device arranged in the indoor unit or other areas of the room, and the detection device can be in communication connection with the controller of the indoor unit so as to transmit the detected data to the controller in real time. In addition, the detecting device may be a single detecting device capable of simultaneously acquiring the lifting speed, the moving speed and the distance of the target object, or may be an assembly of three detecting devices, which are respectively used for acquiring the height, the moving speed and the distance of the target object relative to the indoor unit. For example: the detection device can be an infrared sensor, and the radar is preferably selected in the application, compared with the infrared sensor, the radar has low cost, so that the overall cost of the air conditioner can be reduced.
In detail, radar, a transliteration of the english Radar, derives from the acronym radio detection and ranging, meaning "radio detection and ranging", i.e. finding objects by radio and determining their spatial position. Thus, radar is also referred to as "radiolocation". Radar is an electronic device that detects a target using electromagnetic waves. The radar emits electromagnetic waves to irradiate the target and receives echoes thereof, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the distance change rate (radial velocity), the azimuth, the altitude and the like. The specific uses and structures of the various radars are not the same but the basic forms are consistent, including transmitters, transmitting antennas, receivers, receiving antennas, processing sections and displays. And auxiliary equipment such as power supply equipment, data recording equipment, anti-interference equipment and the like are also provided.
Radar functions similarly to eyes and ears, and of course, is no longer a natural task, while its information carrier is radio waves. In fact, whether visible light or radio waves, are electromagnetic waves in nature, and the speed of propagation in vacuum is the speed of light C, differing in their respective frequencies and wavelengths. The principle is that a transmitter of radar equipment emits electromagnetic wave energy to a certain direction of space through an antenna, and an object in the direction reflects the impinging electromagnetic wave; the radar antenna receives the reflected wave and sends it to the receiving device for processing, extracting certain information about the object (the distance of the target object to the radar, the rate of change of distance or radial velocity, azimuth, altitude, etc.).
The principle of measuring speed is that the radar generates a frequency Doppler effect according to the relative motion between the radar and the target. The target echo frequency received by the radar is different from the radar transmitting frequency, and the difference between the target echo frequency and the radar transmitting frequency is called Doppler frequency. One of the main information that can be extracted from the doppler frequency is the rate of change of the distance between the radar and the target. When the target and the interference clutter coexist in the same spatial resolution unit of the radar, the radar can detect and track the target from the interference clutter by utilizing the difference of Doppler frequencies between the targets and the interference clutter. The principle of measuring target azimuth is to use the sharp azimuth beam of the antenna, and by measuring the elevation beam with a narrow elevation angle, the target height can be calculated according to the elevation angle and the distance. The distance measurement principle is to measure the time difference between the transmitted pulse and the echo pulse, and the electromagnetic wave propagates at the speed of light, so that the distance between the radar and the target can be converted.
S12, comparing the height H with a height threshold H set Motion speed V and motion speed threshold V set Distance S and distance threshold S set Magnitude relation between the two.
Wherein the height threshold H set The device can be preset before delivery, and can be set and adjusted by a user according to actual needs. It is used for distinguishing children from adults, and has height threshold H set Mainly based on average height of adults and children, and the height threshold H is usually set set Less than or equal to 150cm.
Threshold value of motion speed V set The device can also be preset before delivery, and can also be set and adjusted by a user according to actual needs. It has two roles: one is to distinguish whether the target object is an adult or a old man in a low-speed area; and secondly, distinguishing the state mode of the target object in a higher speed area, such as whether the target object is in a constant speed daily mode or a high speed game or motion mode.
Distance threshold S set The device can also be preset before delivery, and can also be set and adjusted by a user according to actual needs. Its function is mainly to distinguish whether the distance of the target object relative to the indoor unit is in a long-distance region or a short-distance region, it can be understood that the target object is in the short-distance region relative to the indoor unitThe distance is smaller than that of the indoor unit in the long-distance area.
S13, determining a state mode of the target object according to the comparison result of the height H, the movement speed V and the distance S, and selecting an operation mode of the indoor unit according to the determined state mode.
The state mode of the target object comprises a child and old person short distance mode, a child and old person long distance mode, an adult daily short distance mode, an adult daily long distance mode, a child daily short distance mode, a child daily long distance mode, a parent-child game mode and a sport mode.
The operation modes of the indoor unit comprise an ultra-low speed wind avoidance mode, a medium speed wind avoidance mode, a high speed wind avoidance mode and a wind following mode.
It should be noted that, the relative terms "ultra-low speed, medium speed and high speed" used herein when describing the operation mode of the indoor unit refer to the wind speed of the fan of the indoor unit, wherein the wind speed of the fan of the indoor unit from the ultra-low speed wind avoidance mode, the medium speed wind avoidance mode to the high speed wind avoidance mode increases progressively, and in the case that the wind speed of the fan meets the progressive trend, a person skilled in the art can set specific values according to the performance parameters such as the power of the indoor unit. In addition, the wind following mode is also divided into an ultra-low speed wind following mode, a medium speed wind following mode and a high speed wind following mode according to the increasing rule of the wind speed of the fan.
In addition, "wind following" used in describing the operation mode of the indoor unit herein means that wind energy directly blows the target object, whereas "wind avoiding" means that wind is prevented from directly blowing the target object, and wind direct blowing or preventing the direct blowing target object can be achieved by adjusting the opening angle of the air deflector.
In order to better understand the indoor unit control method of the air conditioner of the present application, the following will describe the same in detail with reference to fig. 2 and 3, wherein fig. 2 is a detailed step flowchart of the intelligent control mode of fig. 1 when the indoor unit is refrigerating, and fig. 3 is a detailed step flowchart of the intelligent control mode of fig. 1 when the indoor unit is heating. It should be noted that, in order to keep the drawing clean and tidy, latin "&" is used in fig. 2 and 3 of the drawing of the specification instead of chinese "and".
Referring to fig. 2, the indoor unit moves at a speed threshold V during cooling set Comprising a first movement speed threshold value V set1 And a second movement speed threshold V set2 And a first movement speed threshold V set1 Less than the second movement speed threshold V set2 The step S13 specifically includes:
