Description

RF power control method and device

Technical field

The present invention relates to the field of communications, and in particular, to a radio frequency power control method and apparatus.

Background technique

A variety of existing electronic devices have remote control functions, and the conventional infrared remote controllers are generally applied to remote controllers because of low cost and simple wiring. As various functions of electronic products continue to expand (eg, voice transmission, sensor data transmission, etc.), infrared remote controllers have been unable to meet functional requirements, and thus various RF remote controllers have been produced on the market (eg, 2.4G proprietary protocol technology). , Bluetooth remote control, WiFi remote control, etc.).

The radio frequency has been widely applied to the remote controller due to its advantages of non-directionality, fast response speed, two-way transmission, and large amount of data transmission. The application range of the RF remote control is wider, so the energy-saving mode of the RF remote control becomes more important.

The conditions affecting the transmission power of the radio frequency signal transmission include: the transmission efficiency of the transmission line, the conversion efficiency of the antenna at the transmitting end, the receiving sensitivity of the antenna at the receiving end, the structural design of the equipment, and the attenuation caused by environmental conditions. Therefore, in the case of circuit conversion efficiency, antenna conversion efficiency and receiving sensitivity and product structure design have been fixed, to increase the remote control distance, it is necessary to increase the transmission power.

The existing 2.4G proprietary radio frequency remote controller generally uses a fixed transmission power for signal transmission, which limits the remote control distance of the radio remote controller. If the remote control distance is to be increased, the transmission power of the radio frequency signal needs to be increased, but the transmission is increased. The transmit power of the RF signal will increase the power consumption of the RF remote control. If you want to reduce the power consumption of the RF remote control, you need to reduce the transmit power of the RF signal. This will result in insufficient remote control distance, remote control distance and power consumption. It is difficult to balance and the user experience is not good.

detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Step S10: sequentially transmitting a plurality of acknowledgement signals to the receiving end in a manner that the transmit power is decremented or incremented one by one.

Specifically, the remote control device is used as an example to describe the television. When the user controls the television with the remote controller, the remote controller sequentially transmits several confirmation signals to the television in a manner that the transmission power is decremented or incremented one by one, for determining the remote controller. The distance from the television set, in turn, determines the RF transmit power of the remote control. For example, when the remote controller transmits in a manner that the transmission power is decremented one by one, the radio frequency transmission power is P1, P2, P3, P4, P5, and P6, wherein P1 is preferably the maximum transmission power of the remote controller, then P1>P2. >P3>P4>P5>P6, and the difference between P1 and P2 and the difference between P2 and P3 can be equal or different, that is, the uniform decrement between P1, P2, P3, P4, P5 and P6 Or irregularly decreasing. Similarly, when the remote controller transmits in a manner that the transmission power is incremented one by one, it is preferred that the first transmission power is the minimum transmission power of the remote controller, and the increase of the radio frequency transmission power may be the same or different, and may be set according to actual needs. .

Step S20: Determine a signal transmission power according to whether a feedback signal corresponding to the acknowledgement signal fed back by the receiving end is received.

Further, referring to FIG. 2, the step of determining, by using the feedback signal corresponding to the plurality of acknowledgment signals fed back by the receiving end, the transmit power, specifically includes:

Step S21: When several acknowledgment signals are sequentially transmitted to the receiving end in a manner that the transmitting power is decremented one by one, the signal transmitting power is determined according to the transmitting power of the acknowledgment signal corresponding to the received last feedback signal.

Specifically, if the remote controller receives the TV feedback signals K1 (corresponding to P1), K2 (corresponding to P2), K3 (corresponding to P3), and K4 (corresponding to P4), then the acknowledgment signal indicating the transmission power P5 cannot be When the TV receives, that is, the farthest distance beyond the signal transmission, it determines that P4 is the appropriate signal transmission power. In the subsequent operation, P4 is used as the signal transmission power to communicate with the TV, which ensures the validity of the communication. At the same time, it effectively reduces the power consumption of the remote control.

It is worth mentioning that it is also possible to expand on the basis of P4, for example, using P4 as the first acknowledgment signal, and repeating the above steps again to further determine the most suitable signal transmission power, the specific operation is the same as the above embodiment. I will not repeat them here.

Step S22: When a plurality of acknowledgment signals are sequentially transmitted to the receiving end in a manner that the transmitting power is incremented one by one, the signal transmitting power is determined according to the transmitting power of the acknowledgment signal corresponding to the received first feedback signal.

When the remote controller sequentially transmits several acknowledgment signals to the television in a manner that the transmission power is incremented one by one, when the television receives the first acknowledgment signal, the first feedback signal is sent, and the remote controller receives the first feedback signal. After that, it is determined that the transmit power of the first acknowledgement signal corresponding to the first feedback signal is the most suitable signal transmit power, and in the subsequent operation, the transmit power is used as the signal transmit power to communicate with the television, that is, guarantee The effectiveness of the communication, while effectively reducing the power consumption of the remote control.

In the same way, it can be further developed on the basis of the above, and the principle of the extension is the same as that of the above embodiment, and no further description is made here.

The radio frequency power control method of the present invention can ensure the validity of the communication by transmitting the acknowledgment signal in a decreasing or increasing manner by the transmission power and determining the signal transmission power at the time of the interaction according to the received feedback signal of the corresponding acknowledgment signal. Effectively reduces the power consumption of the remote control.

Further, referring to FIG. 3, FIG. 3 is a flowchart of a second embodiment of a radio frequency power control method according to the present invention.

Based on the foregoing embodiment, in the embodiment, before the step of sequentially transmitting the plurality of acknowledgement signals to the receiving end in a manner that the transmit power is decremented or incremented one by one, the method further includes:

Step S30: Send a wake-up signal to the receiving end to wake up the receiving end.

Specifically, when the television is just turned on or in a sleep state, the television needs to wake up in sleep, and the wake-up signal is sent through the remote controller to wake up the television, and the transmit power of the wake-up signal is preferably the maximum emission of the remote controller. Power, but not limited to maximum transmit power.

Further, referring to FIG. 4, FIG. 4 is a flowchart of a third embodiment of a radio frequency power control method according to the present invention.

Based on the foregoing embodiment, in the embodiment, before the step of sending the wake-up signal to the receiving end to wake up the receiving end, the method further includes:

Step S40: determining whether to pair with the receiving end;

If no, step S50 is performed, and a pairing request is sent to the receiving end to perform pairing with the receiving end;

If yes, step S30 is performed to send a wake-up signal to the receiving end to wake up the receiving end.

Specifically, before the remote controller sends a wake-up signal to the television to wake up the television, it is necessary to determine whether the remote controller completes pairing with the television, and if there is no pairing, send the television to the television through the remote controller. Pairing requests to pair between the remote control and the TV to ensure signal interaction between the remote control and the TV. When the pairing is completed, a wake-up signal is sent to the television through the remote controller, and the transmission power of the pairing request is preferably the maximum transmission power of the remote controller, but is not limited to the maximum transmission power.

The transmit power of the signal is the signal transmit power.

When the signal transmitting module 101 sequentially transmits a plurality of acknowledgment signals to the receiving end in a manner that the transmitting power is incremented one by one, the RF power setting module 102 is specifically configured to use the acknowledgment signal corresponding to the received first feedback signal. The transmission power is the signal transmission power.

Specifically, when the remote controller sequentially transmits a plurality of acknowledgment signals to the television in a manner that the transmission power is incremented one by one, when the television receives the first acknowledgment signal, the first feedback signal is sent, and the remote controller receives the first acknowledgment signal. After the feedback signal, it is determined that the transmission power of the first acknowledgment signal corresponding to the first feedback signal is the most suitable signal transmission power, and in subsequent operations, the transmission power is used as the signal transmission power to communicate with the television. That is to ensure the effectiveness of the communication, while effectively reducing the power consumption of the remote control.
