Description

Technical Field

[0001] The present invention relates to the technical field of wireless data transmission, and in particular to a wireless carrier data transmission method. Background Art

[0002] A wireless carrier data transmission system is a technology that transmits data via wireless signals. Its core principle is to use electromagnetic waves to transmit information within the radio frequency band. The system primarily consists of a transmitter, a receiver, and a signal transmission medium (radio waves). The transmitter encodes data into electromagnetic wave signals and transmits them via an antenna. The receiver receives the signals via another antenna and decodes them to recover the original data. Wireless carrier transmission systems employ various modulation schemes, such as amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM), which determine data transmission efficiency and quality. Key system technologies also include channel coding, modulation and demodulation techniques, signaling methods, and noise suppression to ensure stable transmission and high-quality data reception in diverse environments. Wireless carrier data transmission systems are widely used in wireless communications, satellite communications, wireless networks, and other fields, providing critical infrastructure for the modern information society.

[0003] Currently, the main technical means for allocating bandwidth for radio transmission is to divide the radio spectrum into different frequency bands, each of which is allocated to a specific type of service or use. However, this allocation method may result in some frequency bands being allocated to services with lower demand or some frequency bands being idle for a long time, resulting in a waste of spectrum resources. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to solve the technical problem that the existing frequency band allocation method leads to waste of spectrum resources due to low service demand of some frequency bands or long idle time of some frequency bands, the present invention provides a wireless carrier data transmission method, which realizes real-time dynamic allocation of frequency bands by improving the spectrum allocation method, thereby avoiding waste of spectrum resources.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a wireless carrier data transmission method includes: a wireless carrier environment data acquisition unit, a wireless data acquisition unit, the data processing unit, the wireless carrier allocation unit and the output unit, the wireless carrier environment data acquisition unit is used to collect the load data of each frequency band, and uniquely number each frequency band and collect the design load capacity data of each frequency band, and send the collected data to the data processing unit, the wireless data acquisition unit is used to collect the data size and the number of data required to be transmitted this time, and send the collected data size and data number to the data processing unit, and the data processing unit forms multiple frequency band load data sets according to the number of each frequency band and the load data of the corresponding frequency band according to the collection time. And load data sets based on multiple frequency bands Calculate the load fluctuation value FZB of each frequency band separately I , and then according to the average value PJ of the corresponding frequency band load I Design load capacity data EF of the corresponding frequency band I The load status FT of each frequency band is obtained by ratio calculation I And the load fluctuation value FZB of each frequency band I And the load status FT of each frequency band I The data is sent to the wireless carrier allocation unit. The data processing unit calculates the numerical value XF required for the wireless transmission load according to the data size and the number of data received for the wireless data to be transmitted this time, and sends the calculated numerical value XF to the wireless carrier allocation unit. The wireless carrier allocation unit compares and matches the appropriate frequency band according to the received numerical value XF required for the load, and sends the frequency band number after matching to the output unit. The output unit allocates the wireless transmission data required this time to the corresponding frequency band for transmission according to the received frequency band number.

[0006] Therefore, by calculating the load fluctuation value of each channel and the load status of each frequency band, the load status and real-time fluctuation status of each frequency band can be objectively grasped, and the current status of the frequency band can be judged based on these two statuses. At the same time, the load demand value required for this wireless data transmission can be calculated, and the data size of the data transmitted this time can be objectively grasped, and the appropriate frequency band can be matched according to the data size. According to the real-time fluctuation status and real-time load status of the frequency band, a reasonably suitable frequency band can be selected for transmission of the wireless data transmitted this time, and real-time dynamic allocation of frequency bands for wireless data transmission can be realized, avoiding allocating each frequency band to a specific type of service or purpose, resulting in some frequency bands being allocated to services with lower demand or some frequency bands having more idle time, resulting in waste of spectrum resources.

[0007] Furthermore, each frequency band is uniquely numbered as follows:

[0008] A, B, ..., N;

[0009] Load data is expressed as: F;

[0010] The design load capacity data of each frequency band is expressed as:

[0011] SF A , SF B ,…,SF N ;

[0012] Wherein: A~N represent the frequency band numbers corresponding to each load data.

[0013] Furthermore, multiple frequency band load data sets are represented as:

[0014]

[0015] Where AJ to NJ represent the load data sets for the corresponding numbered frequency bands, and 1 to n represent the data sets' numbers in chronological order. Each data point in each set has the same acquisition time and the same number of data points. This ensures that data points in each set have the same acquisition time and number, eliminating the need for data alignment in subsequent calculations, reducing computational steps and increasing computational speed. Furthermore, uniquely numbering each frequency band facilitates quick identification of the corresponding frequency band.

[0016] Furthermore, the method for calculating the load fluctuation value of each frequency band includes the following steps:

[0017] S1. Calculate the average value PJ of the corresponding frequency band load one by one I ;

[0018] S2. Get the average value PJ calculated in step S1 I Calculate the corresponding frequency band load fluctuation value FZB based on the average value I ;

[0019] S3, multiple corresponding frequency band load fluctuation values ​​FZB calculated in step S2 I That is the load fluctuation value of each frequency band.

[0020] Furthermore, the corresponding frequency band load average value PJ I The calculation expression is:

[0021]

[0022] Where: I represents any one of the frequency band numbers A to N. Indicates the load data set corresponding to any one of the frequency band numbers A to N. Indicates the summation calculation of the corresponding load data set. Indicates that the average value of the summed results is calculated, which is the average value PJ of the corresponding frequency band load I .

[0023] Furthermore, in step S2, the corresponding frequency band load fluctuation value FZB I The calculation expression is:

[0024]

[0025] in: It represents the sum of the squares of the difference between the data in the corresponding frequency band load data set and the average value of the corresponding frequency band load. It means to take the average value of the sum of the squares of the differences and take the square root to get the load fluctuation value FZB of the corresponding frequency band. I Therefore, by calculating the load fluctuation value FZB of each frequency band I , can objectively grasp the load fluctuation value FZB of each frequency band I , and can judge the current status of the frequency band based on this, thereby improving the basis for subsequent frequency band selection, realizing dynamic selection of frequency bands, and avoiding the low-load frequency bands being idle for a long time, resulting in a waste of resources.

[0026] Furthermore, the load status FT of each frequency band I The calculation expression is:

[0027]

[0028] Among them: EF represents the frequency band design load capacity data, EF I Indicates the design load capacity data corresponding to any one of the A to N frequency bands. Indicates the average value PJ of the corresponding frequency band load I Design load capacity data EF of the corresponding frequency band I The ratio is the load status of each frequency band. Therefore, by calculating the load status FT of each frequency band I , can objectively grasp the load status of each frequency band FT I , and can judge the current status of the frequency band based on this, thereby improving the basis for subsequent frequency band selection, realizing dynamic selection of frequency bands, and avoiding the low-load frequency bands being idle for a long time, resulting in a waste of resources.

[0029] Furthermore, the load demand value XF is calculated as:

[0030] XF = sj*cs;

[0031] Where sj represents the size of the wireless data, cs represents the number of data transmissions required, and the product of sj*cs represents the load requirement. Therefore, by calculating the load requirement XF required for this wireless data transmission, we can objectively determine the size of the wireless data being transmitted and match the appropriate frequency band based on the data size. Based on the real-time frequency fluctuations and load status, we can select a suitable frequency band for the wireless data being transmitted.

[0032] Furthermore, matching a suitable frequency band includes the following steps:

[0033] A1. The calculated load fluctuation value FZB of each frequency band A ~FZB N Sort in descending order;

[0034] A2. The calculated load status FT of each frequency band A ~FT N Sort in descending order;

[0035] A3. Select the minimum frequency band load fluctuation value FZB Nmin , and observe the load status corresponding to the frequency band with the smallest frequency band fluctuation. When its load status is large, replace the load fluctuation value of the frequency band adjacent to the minimum frequency band load fluctuation value, and observe its corresponding frequency band load status. In this way, match the appropriate frequency band and send the frequency band number to which it belongs to the output unit.

[0036] Furthermore, after receiving the matched frequency band number, the output unit selects the matched frequency band number through the wireless communication module of the wireless carrier device for the data to be wirelessly transmitted and sends the wireless data through the frequency band.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] By calculating the load fluctuation value of each channel and the load status of each frequency band, the load status and real-time fluctuation status of each frequency band can be objectively grasped, and the current status of the frequency band can be judged based on these two statuses. At the same time, the load demand value required for this wireless data transmission can be calculated, and the data size of the data transmitted this time can be objectively grasped, and the appropriate frequency band can be matched according to the data size. According to the real-time fluctuation status and real-time load status of the frequency band, a reasonably suitable frequency band can be selected for transmission of the wireless data transmitted this time, and real-time dynamic allocation of frequency bands for wireless data transmission can be realized, avoiding allocating each frequency band to a specific type of service or use, resulting in some frequency bands being allocated to services with lower demand or some frequency bands having more idle time, resulting in waste of spectrum resources.
