[0046] In modern industrial production environments, especially in high-risk environments such as petroleum, chemical, and mining where flammable and explosive substances are present, safe and efficient communication devices are essential. In order to ensure the safety of personnel and equipment, explosion-proof smart terminals have gradually become key equipment in the industrial Internet of Things. Explosion-proof smart terminals not only need to withstand harsh environments, but also must maintain stable and reliable communication performance to ensure the real-time and accuracy of data. However, in complex industrial environments, 5G communication devices often face challenges from various electromagnetic interference sources, such as large motors, frequency converters, welding equipment, etc. The noise and interference signals generated by these devices will seriously affect the quality of wireless communication, resulting in reduced reliability of data transmission, and may even cause communication interruptions. To this end, the present application provides an explosion-proof smart terminal communication noise reduction method and device based on a 5G industrial gateway to solve the above problems.

[0047] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0048] See also Figure 1 , Figure 1A flow chart of a method for noise reduction in explosion-proof intelligent terminal communication based on a 5G industrial gateway provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes steps S1 to S3.

[0049] Step S1. Obtain a channel parameter information set corresponding to a multi-antenna array through a preset channel parameter acquisition module, and obtain an antenna weight matrix W corresponding to the channel parameter information set based on a preset beamforming algorithm, and adjust the transmission phase and transmission power of each transmitting antenna in the multi-antenna array based on the antenna weight matrix W; the multi-antenna array is used to transmit data information from a 5G industrial gateway to an explosion-proof intelligent terminal, the 5G industrial gateway is provided with multiple transmitting antennas, and the explosion-proof intelligent terminal is provided with multiple receiving antennas.

[0050] The channel parameter information set includes a plurality of channel parameter information, each channel parameter information corresponds to a channel, and each of the channel parameter information includes at least a first transmission phase and a channel gain.

[0051] The method of obtaining the antenna weight matrix corresponding to the channel parameter information set based on a preset beamforming algorithm includes: constructing a channel matrix M based on the channel parameter information set; wherein the elements M in M i，j Representing the first characteristic information corresponding to the channel between the i-th antenna of the 5G industrial gateway and the j-th antenna of the explosion-proof intelligent terminal; the first characteristic information includes a first transmission phase and a channel gain; obtaining the data information of the 5G industrial gateway, and encoding the data information based on a preset vector encoding rule to obtain a coding vector S; obtaining a preset noise matrix N and an objective function in a database; generating the antenna weight matrix W based on the channel matrix M, the coding vector S, the noise matrix N and the objective function; wherein the element W in W i，j Represents the second characteristic information corresponding to the channel between the i-th antenna of the 5G industrial gateway and the j-th antenna of the explosion-proof intelligent terminal; the second characteristic information includes a second transmission phase and transmission power.

[0052] It should be noted that the method for obtaining the noise matrix N includes the following steps:

[0053] When the equipment in the factory is not in operation, obtaining noise power information corresponding to the receiving antenna corresponding to each channel of the multi-antenna array within a preset time period;

[0054] For each of the channels, determining an average noise power corresponding to the channel based on the noise power information corresponding to the channel;

[0055] The noise matrix N is constructed based on the average noise power corresponding to each of the channels; wherein the elements N in N i，j Represents the average noise power corresponding to the channel between the i-th antenna of the 5G industrial gateway and the j-th antenna of the explosion-proof intelligent terminal.

[0056] It should be noted that the objective function is as shown in formula (1), and the antenna weight matrix W is a matrix that maximizes the function value of the objective function:

[0057] (1)

[0059] in, SRN max is the maximum signal-to-noise ratio, W H is the conjugate transposed matrix of the antenna weight matrix W.

[0060] It can be understood that in step S1, the data information of the 5G industrial gateway can be transmitted through the optimal transmission path through the beamforming algorithm, effectively bypassing the interference source, and reducing the signal attenuation of the data information during the transmission process, thereby improving the reliability and stability of data transmission.

[0061] Step S2: obtain the first noise information between the 5G industrial gateway and the explosion-proof intelligent terminal through a preset noise signal detection device, and allocate subcarriers to the channels corresponding to each adjusted transmitting antenna based on the first noise information.

[0062] The allocating subcarriers to the channels corresponding to the adjusted transmitting antennas based on the first noise information includes the following steps:

[0063] Performing spectrum analysis on the first noise information by using a preset Fourier transform algorithm to obtain a spectrum graph corresponding to the first noise information; wherein the abscissa of the spectrum graph represents frequency, and the ordinate represents intensity;

[0064] Determine a valid frequency band based on the spectrum diagram; wherein the intensity corresponding to the valid frequency band is less than a preset intensity;

[0065] Subcarriers are allocated to channels corresponding to each of the adjusted transmit antennas based on the effective frequency band.

[0066] Furthermore, allocating subcarriers to the channels corresponding to the adjusted respective transmitting antennas based on the effective frequency band comprises the following steps:

[0067] For each of the transmitting antennas, the preset subcarrier information corresponding to the transmitting antenna is obtained in the database, and the effective subcarrier information corresponding to the transmitting antenna is determined based on the effective frequency band and the preset subcarrier information; wherein the preset subcarrier information includes a plurality of preset subcarriers corresponding to the transmitting antenna, the effective subcarrier information includes a plurality of effective subcarriers corresponding to the transmitting antenna, and the frequency range corresponding to each of the effective subcarriers is within the effective frequency band; it can be understood that the bandwidths of the channels corresponding to the various transmitting antennas are not consistent, which results in the number of subcarriers of the channels corresponding to the various transmitting antennas being inconsistent, and by setting the preset subcarrier information for the channels corresponding to the various transmitting antennas, it is helpful to improve the stability and reliability during data transmission;

[0068] Counting the first number of effective subcarriers corresponding to each of the transmitting antennas respectively, and arranging the effective subcarrier information corresponding to each of the transmitting antennas in sequence based on the first number corresponding to each of the transmitting antennas, to obtain an effective subcarrier information sequence; wherein the first number corresponding to each effective subcarrier information in the effective subcarrier information sequence increases in sequence;

[0069] Determine deduplication processing basis information in the effective subcarrier information sequence; the deduplication processing basis information includes at least one, and each of the deduplication processing basis information includes multiple effective subcarriers with overlapping frequency intervals;

[0070] Based on each of the de-duplication processing basis information, the subcarriers in the effective subcarrier information sequence are de-duplicated to obtain the target subcarrier information corresponding to each of the transmitting antennas; specifically, including: for each of the de-duplication processing basis information, based on the sequence numbers corresponding to the effective subcarrier information where each effective subcarrier in the de-duplication processing basis information is located in the effective subcarrier information sequence, determining the first target effective subcarrier and the second target effective subcarrier; wherein the sequence number corresponding to the effective subcarrier information where the first target effective subcarrier is located is the smallest, and the second target effective subcarrier is the remaining effective subcarriers in the de-duplication processing basis information except the first target effective subcarrier; for each of the de-duplication processing basis information, deleting the second target effective subcarrier corresponding to the de-duplication processing basis information in the effective subcarrier information sequence to obtain the target subcarrier information corresponding to each of the transmitting antennas;

[0071] Based on the target subcarrier information corresponding to each of the transmitting antennas, subcarriers are respectively allocated to the channels corresponding to each of the adjusted transmitting antennas; specifically, it includes: respectively counting the second number of valid subcarriers in the target subcarrier information corresponding to each of the transmitting antennas, and determining the minimum second number as the target number; for each of the transmitting antennas, allocating the target number of subcarriers to the transmitting antenna based on the target subcarrier information corresponding to the transmitting antenna.

[0072] It can be understood that the method of step S2 first performs spectrum analysis on the noise signal to determine the effective frequency band, ensures that the subcarriers of each channel are allocated in the frequency area with less interference, and reasonably allocates the subcarriers of each transmitting antenna based on the effective frequency band and preset subcarrier information, thereby ensuring the stability and reliability of data transmission during the communication process, and then counts the number of effective subcarriers of each antenna, and based on the de-duplication processing basis information, eliminates the overlapping effective subcarriers between different antennas, further optimizes the utilization of resources, and prevents mutual interference between channels during data transmission. Finally, by allocating the target number of subcarriers to each transmitting antenna based on the target subcarrier information corresponding to the transmitting antenna, it ensures that the number of subcarriers used by each channel during data transmission is matched and balanced, reduces interference, and improves the quality and efficiency of data transmission.

[0073] Step S3, control each transmitting antenna to send the data information of the 5G industrial gateway end to the explosion-proof intelligent terminal through its corresponding subcarrier and channel, and in the process of each transmitting antenna sending the data information of the 5G industrial gateway end to the explosion-proof intelligent terminal through its corresponding subcarrier and channel, obtain the second noise information between the 5G industrial gateway end and the explosion-proof intelligent terminal in real time through a preset noise signal detection device, and obtain the similarity between the first noise information and the second noise information, and when the similarity is less than the preset similarity, start the data information retransmission mechanism.

[0074] Wherein, obtaining the similarity between the first noise information and the second noise information includes the following steps:

[0075] Inputting the first noise information and the second noise information into a preset noise information feature extraction model respectively to obtain a first feature vector and a second feature vector;

[0076] A similarity between the first feature vector and the second feature vector is determined as the similarity.

[0077] It can be understood that after the data information retransmission mechanism is started, the above steps S1 to S3 are executed again.

[0078] The method provided in this embodiment, on the one hand, obtains the channel parameter information set of the multi-antenna array through the channel parameter acquisition module, and adjusts the transmission phase and transmission power of each transmitting antenna in combination with the preset beamforming algorithm, so that the data information of the 5G industrial gateway end can be transmitted through the optimal transmission path, effectively bypassing the interference source, and reducing the signal attenuation of the data information during the transmission process, thereby improving the reliability and stability of data transmission. On the other hand, the first noise information between the 5G industrial gateway end and the explosion-proof intelligent terminal is obtained through the preset noise signal detection device, and based on the first noise information, the subcarriers are allocated to the channels corresponding to each adjusted transmitting antenna, and the subcarriers are allocated to the frequency band with lower noise interference, thereby reducing the noise interference during the communication process, which can effectively improve the reliability and stability of data transmission and help to achieve an efficient and stable industrial 5G communication environment.
