Abstract

[0038] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0039] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.
[0040] Figure 1 This is a flowchart illustrating a sensing range calibration method provided in an embodiment of this disclosure. The sensing range calibration method can be applied to electrical appliances requiring human body sensing to calibrate the sensing working range or the sensing non-working range. This calibration can be performed by the sensing range calibration device provided in this embodiment, which can be implemented using software and / or hardware.
[0041] A method for calibrating a sensing range includes: acquiring the stationary position of a target object and determining the stationary position as the vertex of the required calibration area; acquiring the position of the vertex and determining the coordinates of the point projected onto a horizontal plane; when the number of acquired vertices is equal to 2, using the rectangle enclosed by x = x1, y = y1, x = x2, and y = y2 as the sensing working range or sensing non-working range, wherein x1 and x2 are the abscissas of the two vertices, and y1 and y2 are the ordinates of the two vertices; when the number of acquired vertices is greater than or equal to 3, using the polygon formed by connecting all the vertices sequentially as the sensing working range or sensing non-working range.
[0042] Specifically, such as Figure 1 As shown, when the number of acquired vertices is equal to 2, the sensing range calibration method includes:
[0043] S110, Start calibration mode.
[0044] S120. The person stands at the first vertex of the required calibration area. Specifically, the person stands within the sensing area and determines the stationary position as the first vertex P1 of the required calibration area.
[0045] S130, The vertex is determined by the remote control or app, which is the controller.
[0046] S140. The human body sensor acquires the position (x1, y1) of the point and transmits the information to the processor. The remote control or app is connected to the processor. The first vertex is determined by the remote control or app. The human body sensor acquires the position of the first vertex P1 and transmits the coordinates (x1, y1) of the first vertex P1 to the processor.
[0047] S150. The person stands at the second vertex of the required calibration area. Specifically, the person stands within the sensing area and selects the opposite corner of the required calibration area, determining the opposite corner position as the second vertex P2 of the required calibration area.
[0048] The vertex can be determined via S160, remote control, or app.
[0049] S170. The human body sensor obtains the position (x2, y2) of the point and transmits the information to the processor. Specifically, the human body sensor obtains the determined position of the second vertex P2 and transmits the coordinates (x2, y2) of the second vertex P2 to the processor.
[0050] S180, Confirm that the position calibration is complete.
[0051] S190. The processor processes the position coordinates into a rectangle on the plane coordinate system x0y, bounded by the lines x = x1, y = y1, x = x2, and y = y2. The processor obtains the coordinate position information of each vertex, and encloses the line containing the x-coordinate of the first vertex P1 and the line containing the y-coordinate of the second vertex P2 into a rectangle, and determines this rectangle as the sensing working range or sensing non-working range.
[0052] In other embodiments, such as Figure 3 As shown, when the number of acquired vertices is greater than or equal to 3, the sensing range calibration method includes:
[0053] S210, Start calibration mode.
[0054] S220, n=1, means that the person is determined to be standing at the first vertex P1 of the required calibration area.
[0055] S230. A person stands at the nth vertex of the area to be calibrated, where n is an integer greater than or equal to 3.
[0056] S240, remote control or app determines vertex P nThis remote control or app is the controller.
[0057] S250, The human body sensor acquires the point P. n Position (x) n y n The information is then transmitted to the processor, and steps S230 to S250 are repeated until all vertices are determined to be complete.
[0058] S260, Confirm the completed location coordinates.
[0059] S270. Take line segments P1P2, P2P3...P on the plane coordinate system x0y. n-1 P n P n P1, specifically, line segments P1P2, P2P3...P n-1 P n P n P1 is the line connecting the first vertex P1 and the second vertex P2, the line connecting the second vertex P2 and the third vertex P3, and so on up to the (n-1)th vertex P. n-1 With the nth vertex P n The connection between them, the nth vertex P n The line connecting to the first vertex P1, that is, connecting all vertices in sequence.
[0060] S280. Determine whether the line segments can form a polygonal region. Specifically, the processor receives the coordinate information of each vertex and determines whether connecting all the vertices in sequence can form a polygon.
[0061] S290. Line segments can form a polygonal region. This polygon is taken as the calibration sensing range. That is, line segments P1P2, P2P3...P on the x0y plane coordinate system are taken. n-1 P n P n P1 can form a polygon, which is the sensing working range or the sensing non-working range.
[0062] S300, Line segments cannot form a polygonal region, indicating calibration failure. Recalibrate (see reference). Figure 5 (As shown).
[0063] Furthermore, the steps of obtaining the position of a vertex and determining its coordinates projected onto the horizontal plane specifically include: the target object stands within the sensing area, and its standing position is determined as the first vertex P1 of the required calibration area; the position of the first vertex P1 is obtained and its coordinates (x1, y1) projected onto the horizontal plane are determined; the target object moves n positions sequentially within the sensing area, and the nth position is determined as the nth vertex P of the required calibration area. n Get the nth vertex P nThe location and coordinates of the projection of that point onto the horizontal plane (x) are determined. n y n ); n is an integer greater than or equal to 2.
[0064] Specifically, once the target object is confirmed to be within the sensing area, it can be directly monitored by the app. Alternatively, when the sensing range calibration device is used in smaller spaces such as kitchens or bathrooms, the space itself becomes the sensing area. The calibration mode can be directly entered via remote control, determining the stationary position as the first vertex P1. The human body sensor acquires the coordinates (x1, y1) of the first vertex P1 and transmits this information to the processor. The target object then moves n positions sequentially within the sensing area, determining the positions from the second vertex P2 to the nth vertex P. n The human body sensor acquires the coordinates of each vertex projected onto the horizontal plane and transmits the information to the processor. The number of vertices acquired should be an integer greater than or equal to 2.
[0065] like Figure 2 As shown, to ensure that when the number of vertices obtained is equal to 2, the lines containing the x-coordinates and y-coordinates of the two vertices can form a rectangle, the x-coordinates and y-coordinates of the two vertices must not be equal. That is, when obtaining the coordinates (x1, y1) of the first vertex P1 and the coordinates (x2, y2) of the second vertex P2, x1 and x2 must not be equal, and y1 and y2 must not be equal either. Only then can four lines form a rectangle, which is the sensing working range or the sensing non-working range.
[0066] like Figure 4 As shown, when the number of vertices acquired is greater than or equal to 3, at least one vertex's x-coordinate is not equal to the x-coordinate of the remaining vertices, or at least one vertex's y-coordinate is not equal to the y-coordinate of the remaining vertices. In other words, when acquiring n vertices, at least three non-parallel line segments can be obtained only when at least one vertex's x-coordinate is not equal to the x-coordinate of the remaining vertices, or at least one vertex's y-coordinate is not equal to the y-coordinate of the remaining vertices. These at least three non-parallel line segments, connected sequentially, form a polygon, which is the sensing working range or the sensing non-working range.
[0067] Of course, obtaining the position of a vertex and determining its coordinates projected onto the horizontal plane also includes: obtaining the vertex's position through a sensing device, and using the projection of the sensing device onto the horizontal plane as the origin of the coordinate system. By using the projection of the sensing device onto the horizontal plane as the origin, the obtained vertex position coordinates are calibrated to determine the required calibration area.
[0068] In summary, the sensing range calibration method also includes obtaining the location of the target object after calibration, and executing corresponding functions when the target object is within the required calibration area. Specifically, the sensing range can be calibrated according to the above method. After calibration, the location of the target object is obtained. If the target object is within the required calibration area (i.e., within the sensing range), the processor controls the execution of the corresponding function; if it is outside the required calibration area (i.e., outside the sensing range), the corresponding function is not executed.
[0069] Furthermore, some embodiments of this disclosure also provide a sensing range calibration device, which can be used to perform the steps of any of the sensing range calibration methods in the above embodiments.
[0070] In some embodiments, the sensing range calibration device includes: a first acquisition module configured to acquire target object position information, specifically determining the coordinates of the projection of the target object onto a horizontal plane using the stationary position as the vertex; and a first calibration module configured to, when the number of acquired vertices is equal to 2, use the rectangle enclosed by x = x1, y = y1, x = x2, and y = y2 as the sensing working range or sensing non-working range, wherein x1 and x2 are the abscissas of the two vertices, and y1 and y2 are the ordinates of the two vertices; and when the number of acquired vertices is greater than or equal to 3, use the polygon formed by connecting all the vertices in sequence as the sensing working range or sensing non-working range.
[0071] The sensing range calibration device provided in this embodiment can determine the vertices of the required calibration area based on the acquired target object position information, and determine the coordinates of the vertices projected onto the horizontal plane. The processor receives the coordinates of each vertex and uses them for calibration, thereby determining the sensing range. This prevents users from accidentally triggering the sensing device, thus avoiding resource waste and improving the user experience.
[0072] Furthermore, when the number of vertices acquired is equal to 2, the first calibration module is configured to use the rectangle enclosed by x = x1, y = y1, x = x2, and y = y2 as the sensing working range or sensing non-working range, where x1 and x2 are the x-coordinates of the two vertices, and y1 and y2 are the y-coordinates of the two vertices. Specifically, the coordinates of the two vertices are received, and the rectangle enclosed by the lines containing the x-coordinates and y-coordinates of the two vertices is used as the sensing working range or sensing non-working range.
[0073] When the number of vertices acquired is greater than or equal to 3, the first calibration module is configured to use the polygon formed by sequentially connecting all vertices as the sensing working range or sensing non-working range. Specifically, it receives the coordinates of all vertices, connects every two adjacent vertices into line segments, and then sequentially connects all line segments, thus forming a polygon that serves as the sensing working range or sensing non-working range.

[0076] Of course, the ceiling electrical appliance also includes a controller 404, which includes a remote control, a wired controller, an app, etc. The controller 404 is connected to the processor 402 to perform function selection when the processor 402 controls the function module 401 to run according to the target object's location information.
