[0029] The remote control device and display device provided by the embodiments of the present application will be described in detail below by specific embodiments and their application scenarios in conjunction with the drawings.

[0030] As shown in Figure 1 and Figure 2 The remote control device according to some embodiments of the application includes a remote control body 1, an ultra-wideband receiving module 11, a first control module 12 and a radio frequency communication sending module 13. The ultra-wideband receiving module 11 is arranged at one end of the remote control body 1 and is used to receive a ranging signal sent by an ultra-wideband sending module 21 on a display device and send the ranging signal to the first control module 12. The first control module 12 is arranged in the remote control body 1 and is electrically connected with the ultra-wideband receiving module 11. The first control module 12 is used to determine the ranging signal received by the ultra-wideband receiving module 11 as azimuth data and send the azimuth data to the radio frequency communication sending module 13. The azimuth data is used to represent coordinate information of a corresponding cursor of the remote control body 1 on the display device. The radio frequency communication sending module 13 is arranged in the remote control body 1 and is electrically connected with the first control module 12. The radio frequency communication sending module 13 is used to send the azimuth data sent by the first control module 12 to a radio frequency communication receiving module 22 on the display device so that the display device generates a cursor corresponding to the remote control body 1.

[0031] In the embodiments of the application, the ranging signal sent by the ultra-wideband sending module 21 on the display device is received by the ultra-wideband receiving module 11 and sent to the first control module 12. The first control module 12 determines the ranging signal as azimuth data and sends the azimuth data to the radio frequency communication receiving module 22 on the display device through the radio frequency communication sending module 13 so that the display device generates a cursor corresponding to the remote control body 1 and the cursor is used to perform corresponding operations. Because the ultra-wideband communication technology has higher anti-interference ability and higher positioning accuracy, the cursor generated on the display device is more accurate in positioning and the operation fluency of the remote control device is improved.

[0032] It should be explained that the ultra-wideband (UWB) technology is a wireless communication technology which has the characteristics of using a very large frequency range to transmit data, higher transmission rate, lower power consumption and better anti-interference ability. In the application, the ultra-wideband receiving module 11 is arranged in the remote control device and the ultra-wideband sending module 21 is arranged in the display device so that the ranging signal transmission between the two is used to accurately calculate the position of the cursor corresponding to the remote control device on the display device and avoid inaccurate positioning caused by other signal interference.

[0033] It needs to be explained that the radio frequency communication sending module 13 (Radio Frequency, RF) is electrically connected with the first control module 12. Specifically, the radio frequency communication sending module 13 can adopt communication technologies such as Bluetooth and WIFI to realize wireless communication with the radio frequency communication receiving module 22. Thus, the radio frequency communication sending module 13 sends the orientation data to the radio frequency communication receiving module 22 on the display device, and the display device generates a cursor corresponding to the remote controller body 1 according to the orientation data, so as to facilitate the user to use the cursor for corresponding operation, such as accurate pointing, marking, writing, drawing, page turning, etc.

[0034] In a specific application, the first control module 12 is electrically connected with the ultra-wideband receiving module 11, which can specifically adopt a microcontroller unit (Microcontroller Unit; MCU) or a control chip, etc. The first control module 12 receives the ranging signal sent by the ultra-wideband receiving module 11, and then calculates the ranging signal as orientation data, which is used to represent the coordinate information of the corresponding cursor of the remote controller body 1 on the display device.

[0035] It needs to be explained that in actual application, the display device is provided with at least three ultra-wideband sending modules 21, and the relative positions of each ultra-wideband sending module 21 on the display device are known. The ultra-wideband receiving module 11 receives the ranging signals sent by the ultra-wideband sending modules 21 respectively. The ranging signal actually represents the distance between the ultra-wideband receiving module 11 and the ultra-wideband sending module 21. Then, the first control module 12 establishes a space coordinate system according to the distance between the ultra-wideband receiving module 11 and the ultra-wideband sending module 21, so as to determine the orientation data, which specifically refers to the corresponding coordinate position of the remote controller body 1 on the display device.

[0036] It can be understood that the ultra-wideband sending module 21 sends a ranging signal with a time stamp. The ultra-wideband sending module 21 sends the ranging signal at t0, and the ultra-wideband receiving module 11 receives the ranging signal at t1, so as to calculate the distance d between the ultra-wideband sending module 21 and the ultra-wideband receiving module 11 as d = v (t1-t0), wherein v is the propagation speed of the ranging signal. The distance between each ultra-wideband sending module 21 and the ultra-wideband receiving module 11 can be calculated in this way.

[0037] As Figure 3As shown, the display screen 25 of the display device has a size of 163.5 cm x 92 cm, and four UWB sending modules 21 are arranged on the display device, of which three UWB sending modules 21 are arranged on three corners of the display device. Since the overall size of the display device is known, the relative position data of each UWB sending module 21 can be obtained. The corresponding cursor position of the remote controller body 1 on the display device is M, the distances between the UWB receiving module 11 and the four UWB sending modules 21 are respectively the first distance measuring line a1, the second distance measuring line b1, the third distance measuring line c1 and the fourth distance measuring line d1, forming a spatial quadrangular pyramid shape, the UWB receiving module 11 on the remote controller body 1 is at the top of the quadrangular pyramid, and the corresponding quadrangular pyramid height is the line connecting the remote controller body 1 and the corresponding cursor on the display device. Then, according to d = v (t1-t0), a1 = 85.73 cm, b1 = 72.97 cm and c1 = 144.92 cm can be calculated. Figure 3 As shown, M1 is the feature point of the UWB receiving module 11 on the remote controller body 1, and M2 is the feature point of the corresponding cursor on the display device.

[0038] As shown, Figure 4 The first distance measuring line projection a2, the second distance measuring line projection b2, the third distance measuring line projection c2 and the fourth distance measuring line projection d2 correspond to the orthographic projections of the first distance measuring line a1, the second distance measuring line b1, the third distance measuring line c1 and the fourth distance measuring line d1 on the display screen 25 of the display device respectively. Taking the lower left corner as the origin, a Cartesian coordinate system is established to form X axis, Y axis and Z axis. The coordinates of M1 are M1(x, y, z), and the coordinates of M2 are M2(x, y, 0), as shown, Figure 4 According to the Pythagorean theorem, x 2 +y 2 = b2 2 ; x 2 +(92-y) 2 = a2 2 ; (163.5-x) 2 +(92-y) 2 = c2 2 ; and since a2, b2, c2 and d2 correspond to a1, b1, c1 and d1 respectively, the following can be obtained:

[0039] x 2 +y 2 +z 2 = b1 2 = 72.97 2 ;

[0040] x 2 +(92-y) 2 +z 2 = a12 = 85.73 2 ;

[0041] (163.5-x) 2 +(92-y) 2 +z 2 =c1 2 = 144.92 2 ;

[0042] Based on the above three equations, the specific coordinate values of points M1 and M2 can be calculated, and a fourth equation can be established based on d1 and d2 for verification. If the calculation results differ greatly, it is determined that the calculation signal is incorrect, and the calculation is performed again. It should be noted that the above values are only exemplary descriptions, and the specific values can be changed according to the actual situation.

[0043] It should be noted that the ultra-wideband transmitting modules 21 on the display device can be numbered, so that each ultra-wideband transmitting module 21 transmits a ranging signal according to a predetermined order and interval time to avoid mutual interference.

[0044] As shown in Figure 5 , in some embodiments of the present application, the remote control device further comprises an inertial measurement module 14, which is arranged in the remote control body 1 and is electrically connected with the first control module 12. The inertial measurement module 14 is used to obtain the angle posture data of the remote control body 1 and send the angle posture data to the first control module 12. The first control module 12 is further used to determine the coordinate pointing data based on the angle posture data and the azimuth data.

[0045] In the embodiments of the present application, the angle posture data of the remote control body 1 is obtained by the inertial measurement module 14 and sent to the first control module 12. The first control module 12 determines the coordinate pointing data based on the angle posture data and the azimuth data, so that the coordinate information of the cursor corresponding to the remote control body 1 can be corrected in real time, and the controllability is improved.

[0046] It should be explained that the coordinate pointing data refers to the coordinate information of the cursor corresponding to the remote control body 1 on the display device, in other words, the coordinate pointing data is the correction made by the first control module 12 to the azimuth data based on the angle posture data.

[0047] Exemplarily, as Figure 3 and Figure 4As shown, according to the foregoing, taking the case that the ultra-wideband receiving module 11 is at M1 as an example, when the front end of the remote controller body 1 (i.e. the position where the ultra-wideband receiving module 11 is arranged) is not moved and the rear end is deflected, the remote controller body 1 is re-directed to M3, at this time, the remote controller body 1 is deflected by α in the X direction and by β in the Y direction, since the vertical distance (z) between the remote controller body 1 and the display device does not change, and further according to the Pythagorean theorem, it can be obtained that the coordinate value of M3 is (x+ztanα, y+ztanβ, 0). Thus, according to the angle posture data of the remote control device, the coordinate information of the cursor of the remote controller body 1 on the display device can be corrected in real time, the accuracy of the remote control device is improved, and the controllability of the remote control device is improved.

[0048] It needs to be explained that the inertial measurement module 14 is specifically an IMU (Inertial Measurement Unit) which includes an accelerometer and a gyroscope, so as to obtain three-axis acceleration and three-axis angular velocity in the coordinate system of the remote controller body 1 itself.

[0049] In some embodiments of the present application, the first control module 12 is further configured to determine the movement information of the cursor on the display device according to the ranging signal and the angle posture data, and send the movement information to the display device through the radio frequency communication sending module 13, so that the display device selects the corresponding operation item according to the movement information.

[0050] In the embodiments of the present application, the first control module 12 is further configured to determine the movement information of the cursor on the display device according to the ranging signal and the angle posture data, and send the movement information to the display device through the radio frequency communication sending module 13, so that the display device selects the corresponding operation item according to the movement information, thereby realizing more abundant operations on the display device, improving the controllability of the remote control device, and improving the user experience.

[0051] Exemplarily, the determination of the movement information of the cursor on the display device according to the ranging signal and the angle posture data can be that the cursor of the remote controller body 1 on the display device forms a movement track, and further the movement track information is sent to the display device, and the display device generates a highlight trace on the display screen 25 thereof, in other words, the first control module 12 generates a line on the display device according to the movement and angle rotation of the remote controller body 1, thereby realizing the operation of drawing a line.

[0052] Of course, the related operation item can also be page turning, writing, etc., which can be set according to actual needs by those skilled in the art, and the present application does not limit this.

[0053] As Figure 1As shown, in some embodiments of this application, the remote control device further includes a laser emitting module 15, which is located at one end of the remote control body 1 and electrically connected to the first control module 12. The laser emitting module 15 is used to generate a laser spot.

[0054] In this embodiment, by setting a laser emitting module 15 at one end of the remote control body 1, the user can generate a corresponding laser spot according to actual needs for use in the demonstration, thereby improving the convenience of the remote control device.

[0055] In specific applications, the laser emitting module 15 can be set at the same end of the ultra-wideband receiving module 11 or at different ends. Those skilled in the art can set it according to actual needs, and this application does not limit it in this regard.

[0056] In some embodiments of this application, the remote control device further includes a power module, which is electrically connected to the ultra-wideband receiving module 11, the first control module 12, the radio frequency communication transmitting module 13, the inertial measurement module 14, and the laser emitting module 15, and provides power to the above modules.

[0057] In this embodiment, a power module is provided to supply the electrical energy required by each module for the normal operation of the entire system. The power module may specifically include a battery, a DC conversion module, and a voltage regulator.

[0058] like Figure 1 As shown, in some embodiments of this application, the remote control device further includes a control element 16 and a function module 17. The control element 16 is disposed in the remote control body 1 and associated with the first control module 12, and is used to control the start and stop of the laser emitting module 15. The function module 17 is associated with the first control module 12 and is used to perform corresponding functions on the display device based on the user's input. The function execution includes, but is not limited to, at least one of: tuning, page turning, etc.

[0059] In this embodiment, by incorporating a control element 16 and a functional module 17 into the remote control body 1, the start and stop of the laser emission module 15 can be controlled according to the user's operation, making it convenient for the user. Simultaneously, the display device can perform corresponding functions based on the user's input, such as adjusting volume and turning pages. This improves the operability and convenience of the remote control device.

[0060] In specific applications, the control element 16 and the function module 17 can be at least one of the following: push-button, toggle button, touch button, touchpad, etc. Those skilled in the art can make the settings according to actual needs, and this application does not limit them.

[0061] It needs to be explained that the function module 17 also includes a switching button, which is used to switch the multiple control modes of the remote control device, such as: a physical cursor pointing mode, which is specifically that the laser emitting module 15 works, so that the user guides the audience's eyes through the projected laser spot; or a multifunctional analog cursor mode, which is specifically that a virtual cursor is generated on the display device, and the functions such as accurate pointing and marking are realized through the virtual cursor.

[0062] As shown in the specific application, the infrared emitting module 18 and the radio frequency communication sending module 13 jointly constitute the interaction interface of the remote control device and the display device, and the infrared emission and radio frequency emission of the remote control device are combined with the infrared receiving and radio frequency receiving parts of the display device to realize the remote control of the display device.
