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] The wireless carrier data transmission system is a technology that transmits data through wireless signals. Its core is to use electromagnetic waves to transmit information in the radio frequency band. The system mainly includes: a transmitter, a receiver, and a signal transmission medium (radio waves). The transmitter encodes the data into an electromagnetic wave signal and sends it out through the antenna; the receiver receives the signal through another antenna and decodes it to restore the original data. The wireless carrier transmission system has a variety of modulation methods (such as amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM)), which determine the transmission efficiency and quality of the data. The key technologies of the system also include channel coding, modulation and demodulation technology, signal methods, and noise suppression to ensure stable transmission and high-quality data reception in different environments. The wireless carrier data transmission system is widely used in wireless communications, satellite communications, wireless networks and other fields, providing important infrastructure for the modern information society.

[0003] At present, 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 purpose. 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 and avoids waste of spectrum resources by improving the spectrum allocation method.

[0005] The technical solution adopted by the present invention to solve its technical problem 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 based on multiple frequency band data sets Calculate the load fluctuation value FZB of each frequency band separately I , and then based on multiple frequency band load data sets And the load fluctuation value FZB of each frequency band I Calculate the load status FT of each frequency band I And the load fluctuation value FZB of each frequency band I And the load status FT of each frequency band I The wireless carrier allocation unit calculates the 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, and sends the calculated value XF to the wireless carrier allocation unit. The wireless carrier allocation unit compares and matches the appropriate frequency band according to the received 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 for 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 the current transmission of wireless data can be calculated, and the data size of the current transmission data 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 the current transmission of the wireless data for transmission, 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] Among them: AJ~NJ represent the load data sets of the corresponding numbered frequency bands, 1~n represent the numbers in the corresponding data sets in the order of acquisition time, the acquisition time of each data point in each set is the same, and the number of data points in each set is the same. Therefore, the acquisition time of each data point in each set is the same, and the number of data points in each set is the same, which can avoid data alignment in the subsequent calculation process, reduce the calculation steps, and improve the calculation speed. At the same time, a unique number is set for each frequency band to facilitate the subsequent rapid finding 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 , the corresponding frequency band load fluctuation value FZB is calculated 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 corresponding 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 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] Further, 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 calculate the average value of the sum of the squares of the differences, and the square root of the result is 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 providing a basis for subsequent frequency band selection, realizing dynamic selection of frequency bands, and avoiding low-load frequency bands being idle all the 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 load in a corresponding frequency band I Design load capacity data EF corresponding to the 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 providing a basis for subsequent frequency band selection, realizing dynamic selection of frequency bands, and avoiding low-load frequency bands being idle all the time, resulting in a waste of resources.

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

[0030] XF = sj*cs;

[0031] Among them: sj represents the data size of wireless data, cs represents the number of data transmissions required, and the product of sj*cs represents the load demand value. Therefore, by calculating the load demand value XF required for the current wireless data transmission, the data size of the wireless transmission data can be objectively grasped, and the appropriate frequency band can be matched according to the data size. According to the real-time fluctuation state and real-time load state of the frequency band, a reasonably suitable frequency band can be selected for the wireless data to be transmitted.

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

[0033] A1. Calculate the 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 state corresponding to the frequency band with the smallest frequency band fluctuation. When its load state is large, replace the load fluctuation value of the frequency band adjacent to the minimum frequency band load fluctuation value, and observe the load state of the corresponding frequency band. 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 the output unit receives the matched frequency band number, the data to be wirelessly transmitted this time is sent out through the wireless communication module of the wireless carrier device by selecting the matched frequency band number and sending 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 the current transmission of wireless data can be calculated, and the data size of the current transmission data 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 the current transmission of wireless data for transmission, 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.
