Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
The invention provides a signal transmission system which is used for receiving or transmitting radio frequency signals in an intelligent terminal. The intelligent terminal can perform wireless control through the WiFi module 20 of the router to realize remote control of the intelligent terminal. The intelligent terminal can be an intelligent household appliance, such as an intelligent television, an intelligent sound box 30 and the like, and can also be other intelligent terminal equipment. For convenience of description, the intelligent terminal is taken as the intelligent sound box 30 for example.
Referring to fig. 1 and fig. 2, in an embodiment, the signal transmission system includes: the first main control module 10 is arranged on the intelligent terminal; the antenna 11 is arranged on the intelligent terminal and is electrically connected with the first main control module 10; and the reflecting device 12 is arranged on the intelligent terminal and close to the antenna 11, a gap is formed between the reflecting device 12 and the antenna 11, the reflecting device 12 is provided with a reflecting surface 13, and the reflecting surface 13 is used for reflecting the radio-frequency signal to the antenna 11.
The first main control module 10 is electrically connected with the antenna 11, and the antenna 11 is used for receiving radio frequency signals. The signal source received by the antenna 11 may be a WiFi module 20 of a router. The reflection device 12 is disposed on the smart terminal, and reflects the radio frequency signal radiated onto the reflection surface 13 in the surrounding environment toward the antenna 11, so as to improve the strength of the radio frequency signal received by the antenna 11.
The first main control module 10 may be an existing chip for providing the antenna 11, and the signal transmission system may further include a functional module such as a system power supply module 50 for supplying power to the first main control module 10.
The reflecting device 12 is arranged on the intelligent terminal, the reflecting surface 13 of the reflecting device 12 faces the antenna 11, and when radio-frequency signals in the surrounding environment are radiated to the reflecting surface 13, the reflecting surface 13 reflects the radio-frequency signals to the antenna 11 in a reverse direction. When the intelligent terminal operates, the antenna 11 has a certain function of receiving surrounding radio frequency signals, and under the action of the reflecting surface 13, the strength of the signals received by the antenna 11 is increased, so that the remote control performance of the first main control module 10 is improved.
The shape of the reflection device 12 may be adapted to the shape of the intelligent terminal, for example, as shown in fig. 1, the intelligent terminal has a cylindrical structure, a space for installing the antenna 11 and the reflection device 12 is formed inside the intelligent terminal, and the reflection device 12 forms an arc-shaped outline structure adapted to the intelligent terminal.
The reflecting surface 13 may be one of the surfaces of the reflecting device 12, and is integrally provided with the reflecting device 12. It is also possible to provide the reflecting means 12 on the side facing the antenna 11 with a surface that reflects radio frequency signals to form the reflecting surface 13. When installed, the reflecting surface 13 may be directly disposed toward a radio frequency signal generating device, such as a router. The reflecting surface 13 may be configured to reflect the radio frequency signal, and may also be configured to focus the radio frequency signal radiated onto the reflecting surface toward the antenna. The reflecting surface can be formed by a surface with one shape, and can also be formed by the combination of a plurality of planes and/or curved surfaces so as to improve the focusing performance of the reflecting surface.
For better focusing effect, the reflecting surface 13 is optionally a cambered surface arranged towards the antenna 11. When the radio frequency signal is radiated to the reflecting surface 13, the reflecting surface 13 reflects and focuses the radio frequency signal to the antenna direction, so that the intensity of the radio frequency signal received by the antenna 11 is greatly improved. The reflecting surface 13 may be disposed coaxially with the antenna 11, and radio frequency signals radiated to the reflecting surface 13 from different angles are reflected and focused toward the antenna 11, so as to improve the focusing performance of the reflecting surface 13.
In order to avoid that the reflecting device 12 blocks the radio frequency signal from radiating to the direction of the antenna 11, further optionally, the arc length of the reflecting surface 13 is not more than half of the circumference where the reflecting surface 13 is located, and not less than a quarter of the circumference where the reflecting surface 13 is located. The arc length of the reflecting surface 13 may be one half, one third or one fourth of the circumference on which the reflecting surface 13 is located. When the arc length of the reflecting surface 13 is greater than one-half of the circumference where the reflecting surface is located, the reflecting device 12 blocks signals from radiating to the antenna 11, so that the intensity of the signals received by the antenna 11 is reduced, and radio frequency signal radiation does not exist on part of the surface of the reflecting surface 13, so that surface waste exists. When the arc length of the reflecting surface 13 is less than a quarter of the circumference where the reflecting surface is located, the radio frequency signal radiated to the reflecting surface 13 is relatively low, the radio frequency signal capable of being reflected by the reflecting surface 13 is also relatively low, and the focusing effect is greatly reduced. When the arc length of the reflecting surface 13 is less than one third of the circumference where the reflecting surface is located, the intensity of the radio frequency signal reflected by the reflecting surface 13 is better, and the signal shielding of the signal source is less, so that the intensity of the signal received by the antenna 11 can be greatly improved.
In another embodiment, different from the previous embodiments, the antenna 11 is configured to emit a radio frequency signal, and the reflecting surface 13 is configured to reflect the radio frequency signal emitted from the antenna 11 toward a predetermined direction. After the antenna 11 transmits the radio frequency signal, the radio frequency signal is radiated to the periphery of the antenna 11. Part of the radio frequency signals can be radiated to a preset direction, part of the radio frequency signals can be radiated towards the reflecting device, and the radio frequency signals radiated to the reflecting device are reflected towards the preset direction under the action of the reflecting surface 13. Due to the reflection effect of the reflecting surface 13, the radio frequency signal radiated to the reflecting surface 13 can change direction, and the radio frequency signal can be reflected to a specified preset direction more.
The preset direction is a direction in which a terminal for receiving the radio frequency signal transmitted by the antenna 11 is located. For convenience of description, the antenna 11 is taken as a router antenna, and a terminal for receiving the router signal is taken as a sound box, and the preset direction is a direction of the sound box. The reflecting surface 13 has the functions of reflection and focusing, so that the radio-frequency signal radiated to the reflecting surface 13 can be radiated towards the sound box, and the intensity of the radio-frequency signal received by the sound box is improved. When the reflecting surface 13 is an arc surface, the reflecting surface 13 can reflect radio frequency signals from a plurality of angles to the direction of the sound box, so that the focusing effect can be further improved. In this embodiment, when the reflective surface 13 is too large, part of the radio frequency signals reflected by the reflective surface 13 will not be focused toward the sound box, so that the arc length of the reflective surface 13 is not greater than one half of the circumference, so as to reduce the waste of part of the surface of the reflective surface 13; when the reflecting surface 13 is small, the reflecting effect is relatively low, and the number of radio frequency signals capable of being reflected is relatively small, so that the arc length of the reflecting surface 13 is not less than one fourth of the circumference where the reflecting surface 13 is located, and the signal intensity reflected to the sound box by the reflecting surface 13 reaches the preset requirement.
When the number of the sound boxes for receiving the router signal is multiple, the number of the reflection devices 12 may be multiple, the reflection devices 12 are spaced apart, and the reflection surface 13 of each reflection device 2 is respectively used for reflecting the radio frequency signal radiated onto the corresponding reflection surface 13 to the corresponding sound box direction, so that the radio frequency signals received by the plurality of sound boxes can be all enhanced.
In an embodiment, the predetermined direction is provided with a second main control module 40 for receiving the radio frequency signal. When the first main control module 10 transmits a radio frequency signal through the antenna 11, a part of the radio frequency signal is received by the second main control module 40, a part of the radio frequency signal is radiated to the reflection surface 13 of the reflection device 12, and the reflection surface 13 reflects the radio frequency signal toward the second main control module 40, so as to improve the signal strength in the direction of the second main control module 40, and further improve the remote operation performance of the second main control module 40. The reflecting surface 13 may be an arc surface facing a preset direction, and taking the second main control module 40 arranged in the preset direction as an example, the reflecting surface 13 focuses radio frequency signals towards the second main control module 40.
In one embodiment, the signal transmission system further comprises: the driving mechanism 15 is electrically connected with the first main control module 10 and is in driving connection with the reflecting device 12; the first main control module 10 is configured to control the driving mechanism 15 to drive the reflection device 12 to rotate relative to the antenna 11.
The driving mechanism is connected to the reflection device 12, so that the driving mechanism 15 can drive the reflection device 12 to rotate. The driving mechanism 15 may be a motor or other mechanism capable of driving the reflecting device 12 to move relatively.
When a user adjusts the position of the intelligent terminal and/or the signal source, the driving mechanism 15 may be controlled by the first main control module 10 to adjust the relative position of the reflection device 12, so that the signal strength reflected by the reflection device 12 to the antenna 11 maintains a stable state.
The reflector 12 rotates relative to the antenna 11, so that the reflector 12 can maintain a predetermined reflection performance. When the reflecting surface 13 is an arc surface, the driving device may drive the reflecting device 12 to rotate around the antenna 11, so that the radio frequency signal reflected by the reflecting surface 13 can be always focused on the antenna 11.
The intelligent terminal may be provided with a key or a control module electrically connected to the first main control module 10, and configured to control the first main control module 10, so as to control the driving mechanism 15.
In an embodiment, when the antenna 11 is used for receiving a radio frequency signal, the reflection surface 13 is used for reflecting the radio frequency signal to the antenna 11, and the signal transmission system further includes: the first signal detection device 14 is connected to the first main control module 10, and the first signal detection device 14 is configured to detect the strength of the radio frequency signal received by the antenna 11; the first main control module 10 is further configured to obtain the strength of the radio frequency signal received by the antenna 11, which is detected by the first signal detection device 14, and control the driving mechanism 15 to drive the reflection device 12 to rotate relative to the antenna 11 according to the detected strength of the radio frequency signal. The first main control module 10 receives the radio frequency signal received by the antenna 11, the first signal detection device 14 detects the intensity of the current radio frequency signal, the first main control module 10 determines whether the intensity of the current radio frequency signal meets a preset requirement according to the intensity of the current radio frequency signal, and when the intensity of the current radio frequency signal does not meet the preset requirement, the driving mechanism 15 is controlled, so that the driving mechanism 15 drives the reflection device 12 to rotate, and the angle of the reflection surface 13 is adjusted.
Taking the example that the operation of the intelligent terminal is substantially affected when the intensity of the radio frequency signal received by the antenna 11 is lower than-70 dBm, the intensity of the radio frequency signal received by the antenna 11 needs to meet the preset requirement of not lower than-70 dBm. When the position of the reflection device 12 changes, the first signal detection device 14 may detect the strength of the radio frequency signal received by the antenna 11 when the first reflection device 12 is at a different position, and when it is detected that the strength of the radio frequency signal received by the antenna 11 is not lower than-70 dBm at the current position, the first master control module 10 controls the driving mechanism 15 to stop operating, so that the reflection device 12 is maintained at the current position.
In another embodiment, when the driving mechanism 15 drives the position of the reflection device to change, and when the first signal detection device 14 detects that the strength of the radio frequency signal received by the antenna 11 is not lower than a preset requirement at a plurality of positions, the first main control module 10 controls the driving mechanism 15, so that the driving mechanism 15 drives the reflection device 12 to maintain at a position with the maximum strength of the radio frequency signal in the plurality of positions.
The first main control module 10 detects the strength of the radio frequency signal received by the antenna 11 through the first signal detection device 14 at intervals, and if the strength of the radio frequency signal received by the antenna 11 is found to be less than-70 dBm, the position of the reflection device 12 is adjusted again, and the test is performed again, so that the angle of the antenna 11 is adjusted to find the angle of the reflection surface 13 when the radio frequency signal meets the preset requirement.
In one embodiment, the reflection device 12 has a plurality of reflection bits in the circumferential direction of the antenna 11; the drive mechanism 15 may drive the reflective device 12 to switch between a plurality of reflective positions. When the intensity of the radio frequency signal received by the antenna 11, detected by the first signal detection device 14, is lower than a first preset intensity, the first main control module 10 is further configured to obtain a reflection position corresponding to the radio frequency signal of which the circumferential signal intensity of the antenna 11 is greater than the first preset intensity of the reflection device 12, and control the driving mechanism 15 to drive the reflection device 12 to rotate to the reflection position corresponding to the radio frequency signal of which the signal intensity is greater than the first preset intensity. The first predetermined intensity may be-70 dBm as described in the previous embodiment. The driving mechanism 15 drives the reflection device 12 to rotate relative to the antenna 11, and the plurality of reflection positions may be different positions arranged at intervals or continuously along the circumferential direction of the antenna 11.
The first main control module 10 controls the driving mechanism 15, so that the driving mechanism 15 drives the reflection device 12 to switch between a plurality of reflection positions, when the reflection device 12 is at one or more reflection positions, and the strength of the radio frequency signal received by the antenna 11 is greater than a first preset strength, the corresponding reflection position is an effective reflection position when the intelligent terminal is at the current position, and the first main control module 10 controls the driving mechanism 15 to drive the reflection device 12 to be kept at any effective reflection position.
Optionally, in this embodiment, when the first main control module 10 controls the driving mechanism 15 to drive the reflection device 12 to rotate to the reflection position corresponding to the radio frequency signal with the signal intensity greater than the first preset intensity, the first main control module 10 controls the driving mechanism 15 to drive the reflection device 12 to rotate to the reflection position corresponding to the radio frequency signal with the maximum signal intensity, so that when the reflection surface 13 reflects the radio frequency signal to the antenna 11, the intensity of the radio frequency signal received by the antenna 11 is kept in the optimal state.
By presetting a plurality of reflection positions, the reflection device 12 can be switched between the plurality of reflection positions according to a preset track, so that the movement track of the reflection device 12 is conveniently controlled, and the design complexity of the driving mechanism 15 is reduced.
Optionally, the first main control module 10 is further configured to control the driving device to drive the reflection device 12 to make a circular motion around the antenna 11 as a center of a circle, and divide the circle into a plurality of reflection positions according to a preset radian, and the first main control module 10 is further configured to obtain and store the strength of the radio frequency signal received by the antenna 11, which is detected by the first signal detection device 14 when the reflection device 12 is located at each reflection position.
In this embodiment, the reflection device 12 rotates around the axis of the antenna 11. A circumference 360 ° perpendicular to the axis of the antenna 11, centered on the axis of the antenna 11, may be uniformly divided into 12 equal parts, and the reflecting device 12 rotates 30 ° each time, and measures the rf signal strength at all angles through scanning in sequence, so as to obtain a signal strength list, which stores the rf signal strength values received by the antenna 11 at the angle of the reflecting surface 13 and corresponding angles, and the strength values may define signal strength levels according to a relative protocol, such as WI-FI 11n, and divide the rf signal strength into three levels of greater than-70 dBm, -70dBm to-97 dBm, and less than-97 dBm into three levels of i/ii/iii. In this embodiment, the reflecting surface 13 may be an arc surface, and focusing is performed by using the arc surface, when the reflecting device 12 is located at different positions, the intensity of the radio frequency signal reflected by the reflecting surface 13 can be focused toward the antenna 11, so as to improve the reflection efficiency of the radio frequency signal.
When the strength of the radio frequency signal received by the antenna 11 is lower than a first preset strength, the first main control module 10 obtains, from the stored radio frequency signal received by the antenna 11 corresponding to each reflection position, a reflection position corresponding to the radio frequency signal of which the circumferential signal strength of the antenna 11 is greater than the first preset strength, of the reflection device 12. The first main control module 10 finds out a reflection position corresponding to the condition that the radio frequency signal intensity in the i/ii/iii type list is greater than the first preset intensity according to the signal intensity list, and rotates the reflection surface 13 to the reflection position, so as to receive the radio frequency signal meeting the preset requirement. In this embodiment, the first main control module 10 may obtain, from the radio frequency signal list received by the antenna 11 corresponding to each reflection position, an angle of the reflection surface 13 corresponding to the maximum radio frequency signal received by the antenna 11, and the first main control module 10 controls the driving mechanism 15 to drive the reflection device 12 to rotate to the reflection position corresponding to the radio frequency signal with the maximum signal strength. A plurality of reflection position is followed antenna 11's circumference sets up, works as when reflect meter 12 is located a plurality of reflection positions respectively antenna 11 received radio frequency signal intensity all detects after, acquires reflect meter 12 is in antenna 11 circumference different positions department antenna 11 received signal intensity to can be directly perceived right the angle of plane of reflection 13 is confirmed, and then can confirm intelligent terminal is in under the current position reflect meter 12's specific angle realizes quick adjustment.
