[0018] It should be understood that the specific embodiments described herein are merely intended to explain the present application and not to limit the present application.

[0019] In the field of wireless communication, Internet of Things, etc., reliable transmission of radio frequency signals is the key to ensuring communication quality. The existing technology usually adopts frequency hopping, direct sequence spread spectrum or frequency band switching scheme based on fixed rules, so that the signal jumps between multiple preset frequency points or frequency bands to avoid fixed frequency interference.

[0020] However, the existing frequency hopping or frequency band switching scheme relies on preset discrete frequency points, and it is difficult to respond to the changing electromagnetic environment in real time, resulting in possible communication interruption in the interference scenario.

[0021] To solve the above problems, the present application provides a radio frequency signal variable frequency band planning method, device, equipment and medium, and the present application scheme will be described in detail below.

[0022] Figure 1 A flowchart of a radio frequency signal variable frequency band planning method provided by an embodiment of the present application is shown in the figure. The radio frequency signal variable frequency band planning method is applied to a signal transmission system, and the method can be executed by a radio frequency signal variable frequency band planning device in communication connection with the signal transmission system. The radio frequency signal variable frequency band planning method can include: S11, obtaining an original radio frequency signal of a target communication environment and converting the original radio frequency signal into a data packet sequence, and encapsulating the data packet sequence to obtain a plurality of to-be-processed data packets.

[0023] In the specific implementation process, the system obtains the original information from the signal source of the target communication environment, and the original information is recorded as the original radio frequency signal in this embodiment. Then, the original information is channel encoded and converted into a digital signal sequence suitable for baseband transmission.

[0024] It should be noted that the channel coding can be converted into a binary bit stream, for example. In some embodiments, the original information can also be line encoded according to the requirements of the modulation mode, for example, using NRZ or Manchester coding.

[0025] Further, the converted digital signal sequence is grouped and encapsulated according to a predetermined communication protocol.

[0026] Specifically, first, the digital signal sequence is cut according to a fixed length; then, a synchronization header is added at the head of each data segment for frame synchronization at the receiving end, and a sequence number is added for identifying the order of the data packet, in addition, a check code is added at the end of each data segment, for example, a cyclic redundancy check (CRC) can be used to detect transmission errors at the receiving end; finally, each encapsulated data segment is taken as a data packet to be processed. It should be noted that the fixed length in this embodiment can be set to 256 bytes, and for the last segment of data segment that is less than the fixed length, a specific filler is used to complete the cutting process.

[0027] S12, determine the initial spectrum of each data packet to be processed, and configure the corresponding data packet to be processed based on the initial spectrum to obtain a standardized data packet, and the length of the standardized data packet corresponding to each data packet to be processed is consistent.

[0028] The redundant information configuration can balance the spectrum structure of each data packet to be processed, avoiding the risk of being easily interfered by excessive energy concentration in certain frequency bands.

[0029] In the specific implementation process, first, the Fourier transform is performed on each data packet to be processed to obtain the initial spectrum of each data packet to be processed.

[0030] Further, the corresponding data packet to be processed is configured with redundant information based on the initial spectrum to obtain a standardized data packet, and the length of the standardized data packet corresponding to each data packet to be processed is consistent.

[0031] In one embodiment, in step S12, the corresponding data packet to be processed is configured with redundant information based on the initial spectrum to obtain a standardized data packet, which can specifically include: S121, divide the plurality of initial spectrums into high-frequency dominant spectrums and low-frequency dominant spectrums; S122, if the initial spectrum is a high-frequency dominant spectrum, add low-frequency redundant information to the data packet to be processed; S123, if the initial spectrum is a low-frequency dominant spectrum, add high-frequency redundant information to the data packet to be processed.

[0032] In the specific implementation process, taking a target spectrum in all initial spectrums as an example, first, a frequency demarcation point is set, and the target spectrum is divided into a low-frequency band and a high-frequency band based on the frequency demarcation point. It should be noted that the frequency demarcation point can be set to one-half of the Nyquist frequency or one-fourth of the sampling frequency.

[0033] Further, the amplitude square sum of all frequency components in the low frequency band is calculated respectively as a first energy, and the first energy is used to represent the low frequency total energy, and the amplitude square sum of all frequency components in the high frequency band is calculated respectively as a second energy, and the second energy is used to represent the high frequency total energy; then, the high frequency energy proportion of the initial frequency spectrum is determined based on the first energy and the second energy, and the initial frequency spectrum is divided into a high frequency dominant graph or a low frequency dominant graph based on the high frequency energy proportion.

[0034] Specifically, the ratio between the second energy and the sum of the second energy and the first energy can be taken as the high frequency energy proportion, which is a number between 0 and 1, and can represent the frequency characteristics of the data packet to be processed. The closer the high frequency energy proportion is to 1, the more information changes in the data packet to be processed, and the high frequency component is dominant. Conversely, the closer the high frequency energy proportion is to 0, the more information changes in the data packet to be processed, and the low frequency component is dominant.

[0035] Further, the high frequency threshold and the low frequency threshold are set. For example, the high frequency threshold is set to 0.6 and the low frequency threshold is set to 0.4. The initial frequency spectrum greater than the high frequency threshold is taken as the high frequency dominant graph, and the initial frequency spectrum less than the low frequency threshold is taken as the low frequency dominant graph.

[0036] Further, if the initial frequency spectrum is a high frequency dominant graph, low frequency redundant information is added to the data packet to be processed; if the initial frequency spectrum is a low frequency dominant graph, high frequency redundant information is added to the data packet to be processed.

[0037] Specifically, for the high frequency dominant graph, a low frequency data sequence with gentle changes (for example, a low frequency sine wave sample with a period or a sequence of all 0s) is generated. Then, the low frequency data sequence is inserted into the original data packet to be processed according to a predetermined mode (for example, it can be appended at the end or at the beginning of the packet). For the low frequency dominant graph, a high frequency data sequence with sharp changes (for example, a high frequency sine wave sample or a pseudo-random code) is generated. Then, the high frequency data sequence is inserted into the original data packet to be processed according to a predetermined mode (for example, it can be appended at the end or at the beginning of the packet).

[0038] It should be noted that in the present embodiment, the system needs to statistically determine the length of all the filled data packets in real time or in advance, determine the maximum length, and perform secondary filling on the data packets to be processed with a length less than the maximum length.

[0039] For example, a fixed filling code such as all 0s or the filling method described above for the high frequency dominant graph and the low frequency dominant graph can be used to supplement the length of the data packet to be processed with a length less than the maximum length to the maximum length.

[0040] Thus, a plurality of data packets to be processed with consistent length are obtained, and the plurality of data packets to be processed with consistent length after the padding processing are taken as standardized data packets in the embodiment.

[0041] S13, assigning an optimal transmission frequency band to each standardized data packet based on the initial spectrum diagram, and generating a frequency conversion control signal; S14, modulating and transmitting each standardized data packet to the optimal transmission frequency band in response to the frequency conversion control signal.

[0042] The frequency conversion control signal can control the modem to set the carrier frequency to a specific optimal transmission frequency band.

[0043] In the specific implementation process, first, the frequency band characteristics of each frequency band in the available frequency band library are determined; then, for any standardized data packet, the optimal transmission frequency band corresponding to the standardized data packet is selected based on the high-frequency energy proportion corresponding to the standardized data packet and the frequency band characteristics in the available frequency band library.

[0044] Specifically, the frequency bands from the highest frequency to the lowest frequency in the available frequency band library are selected as the optimal transmission frequency bands of the standardized data packets in order from high to low according to the high-frequency energy proportions corresponding to the standardized data packets.

[0045] Further, the corresponding frequency conversion control signal is generated according to the optimal transmission frequency band selection result. It should be noted that the modem modulates the digital signal of the standardized data packet to a specified radio frequency carrier in a frequency modulation manner to generate a final transmission signal in response to the frequency conversion control signal.

[0046] Further, the modulated signal can be amplified by a power amplifier and finally transmitted through an antenna at the locked optimal transmission frequency band.

[0047] On the basis of the above embodiment, Figure 2 The flowchart of the radio frequency signal variable frequency band planning method provided by Embodiment Two of the present application is provided, the radio frequency signal variable frequency band planning method is applied to a signal transmission system, and the method can be executed by a radio frequency signal variable frequency band planning device in communication connection with the signal transmission system.

[0049] It can be understood that the embodiment increases step S23 and improves step S24 on the basis of the above-mentioned embodiment.

[0050] It should be noted that the signal transmission system includes a spectrum sensing module, which is used to monitor the signal strength of each sub-band in real time, and through energy monitoring technology, identify which frequency bands are in idle state, which are occupied, and which frequency bands have high signal-to-noise ratio (SNR).
