Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step are within the scope of the present invention.
Example 1: a virtual remote control method for an electrical appliance.
A virtual remote control method of electrical equipment comprises the following specific steps:
the remote control terminal is formed by the virtual imaging module and the millimeter wave radar module, wherein the virtual imaging module can project and image in the air (such as an air screen) to generate a virtual operation interface, and displayed contents can be automatically switched according to different devices. If mathematical modeling is carried out on the virtual interface, the millimeter wave radar can acquire the position and distance information of an entity (such as a finger) appearing on the virtual interface, and the input control instruction can be recognized through algorithm processing, so that the running state of the electrical equipment is controlled.
When a user inputs an instruction for controlling certain electric equipment, the central controller controls the millimeter wave radar to detect the position S1 and the height H1 of the user according to the instruction, and the virtual imaging equipment generates a virtual operation interface with a central point M and an area M1 at the position S2 away from the human body. For this part, the following is exemplified:
as shown in fig. 1, S1 is the distance between the remote control terminal and the point (point K) where the height 3/4H 1 of the human body is located, the vertical distance between the remote control terminal and the ground is H2, the distance between the vertical projection and the vertical projection of the human body on the ground is d1, S2 is perpendicular to H1, and S3 is the distance between the remote control terminal and the point M. H1, S1, S2 and H2 are known quantities, the angle θ and the distance S3 at which the remote control terminal generates the virtual interface M1 can be derived from the following formulas.
The geometrical relationship shows that:
formula one;
a formula two;
a formula III; substituting the first equation into the second equation to obtain the magnitude of theta; substituting theta into equation three, the relation between S3 and S1 can be obtained. Therefore, within the detection range of the remote control terminal, the virtual interface can be automatically adjusted according to the position of the user, and flexible and quick control is realized. Meanwhile, in order to meet the convenience of users with different heights using the virtual interface, the remote control terminal automatically adjusts the distance S2 between the virtual interface and the user according to the height, that is, S2 changes with H1, and the two satisfy the proportional relation of formula 4:
and k is a proportionality coefficient.
A plane coordinate system (X, Y) is established for the virtual interface M1, and then the image or character displayed on M1 has a corresponding coordinate point. When the virtual interface has no input instruction, the millimeter wave radar can not detect the distance of any coordinate on the M1; when an instruction is input into the virtual interface, the millimeter wave radar can detect the distance of some coordinates on the M1, and the instruction input by the user can be judged by processing the coordinates and the distance through an algorithm, wherein the detection method is called as a coordinate distance method. Assuming that fig. 2 is a virtual interface, each small square represents a point (hereinafter, referred to as a detection point) that can be detected by the millimeter wave radar with the minimum detection accuracy, the yellow portion represents a certain function or option composed of four detection points, when the user selects the function or option by means of finger touch, the distance corresponding to the detected coordinates (3, 3), (3, 4), (4, 3), (4, 4) of the millimeter wave radar is S4, the central controller performs a difference operation on S4 and S3, and if the difference value is smaller than a given threshold value, it can be determined that the user selects the function or option. The user places a finger on a certain area on the virtual interface, the area represents a certain function, the distance S4 of the finger is detected by the millimeter wave radar, and S3 is the distance of the millimeter wave radar to the center point M of the virtual interface M1.
The virtual interface is three-dimensionally modeled by the virtual imaging module through an algorithm and then projected into a space, namely, the relation of the distance, the angle and the like between each point on the virtual interface and the central point M can be known from the three-dimensional model. The radar sensor has acquired the data of the three-dimensional model, and therefore, when S4 is detected, by making a difference (or performing a relational operation) with S3 and then comparing the difference with the data in the three-dimensional model, when the data match, which point in the three-dimensional model is obtained.
The advantage of this embodiment lies in, has effectively solved the fragile, poor stability, not general scheduling problem that exist of current entity remote controller, provides the mode of different electrical equipment of a nimble, simple control, can satisfy the experience sense of user's operation, accords with the trend of future intelligent house development.
Example 2: a computer readable storage medium.
A computer-readable storage medium for storing a computer program which, when called by a processor, implements the virtual remote control method of an electric appliance described in embodiment 1.
Example 3: an intelligent household appliance.
An intelligent household appliance comprises a processor and a memory, wherein the memory is used for storing a computer program, and the computer program realizes the virtual remote control method of the electric appliance equipment in embodiment 1 when being called by the processor.
Example 4: an air conditioner.
An air conditioner comprises a processor and a memory, wherein the memory is used for storing a computer program, and when the computer program is called by the processor, the virtual remote control method of electric equipment in embodiment 1 is realized, and the specific steps are as follows:
(1) after the user wakes up the virtual interface, the user selects the electrical equipment to be operated, such as an air conditioner. The central controller obtains the current state information of the air conditioner (such as refrigeration 24 ℃, left and right, up and down air sweeping switches and middle wind blocking speed) from the server, and displays the information on a virtual interface through the virtual imaging module.
(2) The user inputs control instructions, such as refrigeration at 20 ℃, and opens the air sweeping device to sweep air from left to right, up and down and achieve super-strong wind blocking speed. And the millimeter wave radar detects the coordinates and the distance pressed by the finger on the virtual interface in real time according to a coordinate distance method, and sends the data to the central controller for algorithm processing.
(3) The central controller judges the corresponding function according to the coordinate and the distance, identifies a control instruction input by a user, controls the state of the air conditioner according to the instruction, and updates the state to the server.
The above description is only for the preferred embodiment of the present invention, but the present invention should not be limited to the embodiment and the disclosure of the drawings, and therefore, all equivalent or modifications that do not depart from the spirit of the present invention are intended to fall within the scope of the present invention.
