[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 2 , the present invention provides a technical solution:

[0023] See also Figure 1 In the first embodiment of the present invention, a method for intelligently controlling a radio frequency link is provided. In the method, a user obtains audio data from the Internet, and by analyzing the background data during the user's audio viewing process, the radio frequency link of the transmitting end is intelligently controlled, and the audio is distributed to different channels for transmission. Under the premise of not affecting the user experience, the audio transmission power is reduced, thereby reducing the energy consumption of the device. The method includes the following steps:

[0024] S1. Divide the audio data into data packets of the same size, and distribute the divided data packets to different channels for transmission; collect parameter data during the data packet transmission process; the parameter data includes the signal power and transmission rate of the data packets sent in different channels.

[0025] Furthermore, during the audio data transmission process, at the transmitting end, the RF link converts the digital signal corresponding to the data packet into a RF signal, and sends it to the receiving end through different channels. At the receiving end, the RF link receives the RF signals sent by different channels, converts the received RF signals into digital signals, splices them according to the data packets corresponding to the digital signals, obtains the transmitted audio data, and caches the transmitted audio data in the background of the player; wherein each channel corresponds to an independent RF link.

[0026] It should be noted that dividing the audio data into data packets of the same size helps to achieve parallel transmission of the audio data. Since different channels have different frequency characteristics, allocating the divided data packets to different channels for transmission can reduce interference between channels and improve data quality.

[0027] In this embodiment, the RF link is intelligently controlled through a RF SIP module with a frequency-adjustable antenna; the audio data is divided into data packets of the same size, allocated to different channels, and continuously transmitted, and the signal power of the data packets sent in different channels is dynamically adjusted until the audio data stops transmitting; wherein, during the audio data transmission process, the priority of the data packet transmission is divided according to the time series of the audio in the audio data, and the data packets with higher priority are transmitted first, so that the audio data is transmitted sequentially.

[0028] S2. Splicing the transmitted data packets to obtain the transmitted audio data; the user views the transmitted audio data through the player, and collecting the background data of the user's audio data viewing process; the background data includes the remaining playback time of the currently received audio data and the maximum storage memory of the audio data.

[0029] Furthermore, the maximum storage memory for audio data indicates the maximum audio data memory allowed to be cached in the background of the player; when the user views the transmitted audio data through the player, the user can fast forward, rewind, pause and continue playing the viewed audio data in the player. The player determines the current audio data loading stage according to the user's operating instructions, and determines the remaining playback time of the currently received audio data according to the audio data cached in the background of the current player and the current audio data loading stage.

[0030] It should be noted that the current audio data loading stage is determined based on the user's fast forward, fast rewind, pause and continue playback operation instructions. When the user's fast forward or fast rewind operation exceeds the audio data cached in the current player background, that is, the remaining playback time of the currently received audio data is 0, the signal power of the data packets sent in each channel is adjusted to the maximum, and the audio data is transmitted; when the user's corresponding operation instructions do not exceed the audio data cached in the current player background, the signal power of the data packets sent in different channels is analyzed according to the remaining playback time of the currently received audio data, thereby improving the adaptability of the system.

[0031] S3. Analyze the collected parameter data, establish an interference analysis model, fit the relationship curve of the influence of the signal power of the data packet sent in different channels on the data packet transmission rate, and obtain the influence weight of the signal power of the data packet sent in different channels on the data packet transmission rate.

[0032] Specifically, the method steps are:

[0033] S31, analyzing the collected parameter data to obtain a set of signal power and transmission rate of data packets sent in different channels in the parameter data. , , ;

[0034] in, Indicates A set of signal powers and transmission rates of data packets sent in different channels in the parameter data; ; Indicates the amount of parameter data collected and analyzed; Indicates The signal power and transmission rate of data packets sent in different channels in the parameter data; Indicates The first parameter in the data The signal power and transmission rate of the data packets sent in the channel; ; Indicates the number of sending channels, ; Indicates The first parameter in the data The signal power of the data packet sent in the channel; Indicates The first parameter in the data The transmission rate of data packets sent in the channel;

[0035] S32, establish an interference analysis model, and analyze the signal power of data packets sent in different channels according to the parameter data analysis results and Shannon's theorem. As independent variable , will analyze the transmission rate of data packets sent in different channels As dependent variable , fitting the relationship curve of the influence of signal power of data packets sent in different channels on data packet transmission rate:

[0036] ;

[0037] According to the least squares method, we can determine and The value of ; where Indicates The channel bandwidth in a channel and the channel bandwidth in different channels are determined; Indicates The dependent variable is the transmission rate of data packets sent in the channel; Indicates The independent variable of the signal power of the data packet sent in the channel; They respectively represent the influence weights of the signal power of data packets sent in different channels on the data packet transmission rate; Indicates The impact of other conditions in the channel on the data packet transmission rate.

[0038] It should be noted that the transmission rate of the data packet transmission refers to the data packets transmitted per unit time; during the data packet transmission process, the signal power in different channels will interfere with the data packet transmission, so the bit error rate of the transmitted data packet is monitored. When the data packet bit error rate is too high, resulting in incorrect data packet transmission, the sender retransmits the erroneously transmitted data packet. Since the transmission rate of the data packet transmission is the data packets transmitted per unit time, the erroneously transmitted data packets will cause the transmission rate of the data packet transmission to be reduced.

[0039] It should be noted that Indicates the channel bandwidth in different channels, that is, the frequency range in which signals can be transmitted in different channels; Indicates the signal power of data packets sent in different channels, that is, the total power of useful signals transmitted in different channels; It represents the influence of other conditional factors in different channels on the data packet transmission rate, that is, the background noise power of other conditional factors in different channels; according to Shannon's theorem, the maximum data transmission rate that the channel can achieve under given bandwidth and signal-to-noise ratio is analyzed. In actual situations, due to the uncertainty of interference factors, the data packet transmission rate in different channels is often lower than the maximum data transmission rate. By establishing an interference analysis model, the influence of the signal power of data packets sent in different channels on the data packet transmission rate is analyzed, and the interference factor is divided into other conditional interference factors and signal power interference factors of data packets sent in different channels. According to the least squares method, the analyzed parameter data points are substituted into the above relationship curve for fitting, so as to determine and different relationship curves The value of .

[0046] S43, according to the calculation , the signal power of data packets sent in different channels is dynamically adjusted until the audio data stops transmitting.

[0047] It should be noted that by calculating the signal power that needs to be adjusted for sending data packets in different channels and analyzing the impact of changes in the signal power of data packets sent in different channels on the data packet transmission rate, the signal power sent by each channel is dynamically adjusted without affecting the user experience, thereby reducing equipment energy consumption and improving the system's adaptability and resource utilization.

[0050] In this implementation, the administrator checks the signal power of data packets sent in different channels through the interactive platform.
