[0059] Step S2, obtaining a historical noise information set of each transmission channel between the 5G industrial gateway and the central control system at the current moment, and obtaining the noise information of each transmission channel between the 5G industrial gateway and the central control system at the current moment based on a preset noise detection device; the 5G industrial gateway and the central control system transmit data through a multi-antenna array, one antenna corresponds to one transmission channel, and the communication frequency bands corresponding to each transmission channel are different.

[0060] Step S3: for each of the transmission channels, allocate subcarriers to the transmission channel based on the historical noise information set, noise information and communication frequency band corresponding to the transmission channel.

[0061] Step S4: For each of the transmission channels, the preprocessing result is transmitted from the 5G industrial gateway to the central control system based on the subcarrier corresponding to the transmission channel.

[0062] In this embodiment, as described in step S1 above, the data is preprocessed using an edge detection algorithm to obtain a preprocessing result of the data. Specifically, after the explosion-proof intelligent terminal collects the data, the data is preprocessed using an edge detection algorithm to obtain a preprocessing result. It can be understood that preprocessing the data using an edge detection algorithm helps to reduce the computing power of the central control system and improve the stability of the operation of the industrial system.

[0063] As described in step S2 above, a historical noise information set of each transmission channel between the 5G industrial gateway and the central control system at the current moment is obtained, and the noise information of each transmission channel between the 5G industrial gateway and the central control system at the current moment is obtained based on a preset noise detection device. Specifically, for each of the transmission channels, a historical noise information set of the transmission channel is obtained in a database based on the channel coding of the transmission channel, and the noise information of each transmission channel between the 5G industrial gateway and the central control system at the current moment is obtained based on a preset noise detection device for the transmission channel.

[0064] As described in the above step S3, for each of the transmission channels, subcarriers are allocated to the transmission channel based on the historical noise information set, noise information and communication frequency band corresponding to the transmission channel. Specifically, for each of the transmission channels, the effective communication frequency band of the transmission channel is determined based on the historical noise information set, noise information and communication frequency band corresponding to the transmission channel, and subcarriers are allocated to the transmission channel based on the effective communication frequency band. It can be understood that allocating subcarriers to the transmission channel based on the effective communication frequency band helps to improve the communication stability and data integrity of the data during the transmission process.

[0065] As described in step S4 above, for each of the transmission channels, the preprocessing result is transmitted from the 5G industrial gateway to the central control system based on the subcarrier corresponding to the transmission channel. Specifically, for each of the transmission channels, the preprocessing result is added to the subcarrier corresponding to the transmission channel, and the subcarrier to which the preprocessing result is added is transmitted from the 5G industrial gateway to the central control system.

[0066] The method provided in this embodiment, on the one hand, by preprocessing the data using an edge detection method to obtain the preprocessing result of the data, can reduce the computing power of the industrial central control system and help maintain the stability of the industrial system. On the other hand, by adopting a multi-antenna array to transmit information between the 5G industrial gateway and the central control system, and setting a different communication frequency band for the transmission channel of each antenna of the multi-antenna array, it helps to improve the anti-interference ability of information during transmission and ensure the stability of communication. On the other hand, by allocating subcarriers to the transmission channel based on the historical noise information set, noise information and communication frequency band corresponding to the transmission channel, it helps to further improve the communication stability and data integrity during data transmission.

[0067] In some embodiments, the allocating subcarriers to the transmission channel based on the historical noise information set, noise information and communication frequency band corresponding to the transmission channel comprises the following steps:

[0068] Determine an effective communication frequency band of the transmission channel based on a historical noise information set, noise information, and a communication frequency band corresponding to the transmission channel;

[0069] Subcarriers are allocated to the transmission channel based on the effective communication frequency band.

[0070] In this embodiment, determining the effective communication frequency band of the transmission channel based on the historical noise information set, noise information and communication frequency band corresponding to the transmission channel includes the following steps:

[0073] For each of the historical spectrum graphs, determining a historical invalid communication frequency band of the historical spectrum graph; wherein the intensity corresponding to the historical invalid communication frequency band is greater than a preset intensity;

[0074] Determine the overlapping frequency band of each of the historical invalid communication frequency bands as the first target invalid communication frequency band; wherein the first target invalid communication frequency band refers to a frequency band that overlaps with at least two historical invalid communication frequency bands, for example: the historical invalid communication frequency bands include [100HZ, 350HZ], [250HZ, 400HZ], [200HZ, 500HZ], then the first target invalid communication frequency band is (200HZ, 400HZ).

[0076] Determine a second target invalid communication frequency band corresponding to the spectrum graph; wherein the intensity corresponding to the second target invalid communication frequency band is greater than a preset intensity;

[0077] The effective communication frequency band is determined based on the communication frequency band, the first target invalid communication frequency band and the second target invalid communication frequency band. Specifically, the overlapping frequency band of the communication frequency band and the first target invalid communication frequency band is deleted from the communication frequency band to obtain an intermediate effective communication frequency band, and the overlapping frequency band of the intermediate effective communication frequency band and the second target invalid communication frequency band is deleted from the intermediate effective communication frequency band to obtain the effective communication frequency band. For example, the communication frequency band is [30HZ, 800HZ], the first target invalid communication frequency band is [200HZ, 400HZ], and the second target invalid communication frequency band is [300HZ, 600HZ], then the intermediate effective communication frequency band is (30HZ, 200HZ), (400HZ, 800HZ), and the effective communication frequency band is (30HZ, 200HZ), (600HZ, 800HZ).

[0078] The method provided in this embodiment, on the one hand, can effectively avoid the frequency band that has been interfered by noise for a long time by determining the overlapping frequency band of the historical invalid communication frequency band as the first target invalid communication frequency band, thereby improving the stability and reliability of the communication channel; on the other hand, by determining the effective communication frequency band based on the communication frequency band, the first target invalid communication frequency band and the second target invalid communication frequency band, the effect of maximizing the effective communication frequency band is achieved, and the stability and reliability of the communication channel are further improved.
