At the same time, other waveform signal interference will be encountered during the communication process, thus affecting the remote monitoring transmission of power. Summary of the invention

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A first aspect of the present invention provides an anti-interference communication system for power monitoring, comprising:

[0008] The communication security authentication module is configured to: encrypt the pre-processed and transmitted data, and perform security authentication on each terminal accessing the data;

[0009] The antenna intelligent control module determines the transmission direction and angle between the signal output end and the signal receiving end based on the pre-processed data, and performs corresponding regulation;

[0010] The adaptive adjustment module is configured to: receive pre-processed data, use analysis operations to detect interference data within the transmission band, obtain the required extended spectrum through screening, transmit the instructions of the extended spectrum to the synthesizer for control, and use the spectrum adjustment operation to achieve anti-interference.

[0011] Furthermore, it also has a signal output terminal for compressing the data and completing the data signal transmission operation through the antenna.

[0012] Furthermore, it also has a signal receiving end, which completes the decompression and receiving operation of the data signal through the antenna; the received data is displayed through a visual display interface.

[0013] Further, preprocessing, specifically:

[0014] Establish a classification model based on the processing data required by the monitored power system, and extract and mark the title type data in the classification model;

[0015] Introduce the collected data into the classification model, match the corresponding text content in the data with the title type data content, retain the data with the same title type data content in the collected data and the classification model, and filter out the unmatched data;

[0016] The matching classification model with the result data is compensated and the data is aggregated to form the initial data set.

[0017] Furthermore, a compensation operation is performed on the matched classification model with result data, specifically:

[0018] By performing a result data search operation on the classification model with result data, the small type node data under each title type is identified;

[0019] Mark the missing or erroneous results of small-type node data, and compensate for the corresponding small-type node data according to the database;

[0020] For missing anomalies, first determine whether the database has small-type node data content. If not, there is no result data. Otherwise, the missing result data is added from the database to the classification model.

[0021] Further, security authentication is as follows:

[0022] After the encryption operation is performed based on the data to be transmitted, the data transmission operation is completed through the signal output terminal;

[0023] When the signal receiving end performs the receiving operation, it completes the first security authentication operation by inputting the key;

If the match is not performed within the threshold time or the match is wrong, the decryption operation cannot be completed. Otherwise, the decompression receiving operation is realized.

[0025] Furthermore, in the antenna intelligent control module, the transmission direction and angle between the signal output end and the signal receiving end are determined according to the preprocessed data, and corresponding regulation is performed, including the following steps:

[0029] Furthermore, the transmission directions of the antennas at the signal output end and the signal receiving end are adjusted to keep the transmission directions relative to each other, specifically:

[0030] Processing is performed in a plane image of the positioning data of the signal output end and the signal receiving end, and a plane coordinate axis is established with the center of the end face of the signal output end in the image as the center point, an X axis is established with the antenna direction of the signal output end, and a Y axis at right angles to the X axis is established in the horizontal plane of the image, and the position of the signal receiving end is located within the first quadrant of the plane coordinate axis;

[0031] The coordinates of the center of the end face of the signal receiving end are set to P1 (x1, y1), and the angle α of the horizontal rotation of the signal output end is calculated according to the tangent function, and the signal output end rotates counterclockwise by the angle α according to the calculation result;

[0032] Set the endpoint coordinates of the signal receiving end antenna to P2 (x2, y2), and determine the rotation angle of the signal receiving end antenna according to the numerical values ​​of P1 (x1, y1) and P2 (x2, y2);

[0033] If x2≥x1, y2≥y1, the clockwise rotation angle β of the signal receiving antenna is obtained, as shown in the following formula: γ1 is the angle of the signal receiving end antenna rotated clockwise to the horizontal position of the X-axis, β = γ1 + 180° - α;

[0034] If x2≥x1, y2<y1, the clockwise rotation angle β of the signal receiving antenna is obtained, as shown in the following formula: γ2 is the angle of the signal receiving end antenna rotated counterclockwise to the horizontal position with the X-axis, β = 180° - α - γ2;

[0035] If x2<x1, y2≥y1, the clockwise or counterclockwise rotation angle β of the signal receiving antenna is obtained, as shown in the following formula: γ3 is the angle of the signal receiving end antenna rotated clockwise to the horizontal position with the X-axis, β = |α-γ3|;

[0036] If x2<x1, y2<y1, the counterclockwise rotation angle β of the signal receiving antenna is obtained, as shown in the following formula: γ4 is the angle of the signal receiving end antenna when rotated counterclockwise to the horizontal position with the X-axis, β=α+γ4.

[0037] Furthermore, the antenna angle is calculated and adjusted according to the set angle, specifically:

[0038] Processing the vertical plane image of the positioning data of the signal output end and the signal receiving end, establishing the vertical plane coordinate axis with the center of the end face of the signal output end or the center of the signal receiving end in the image as the center point, establishing the M axis directly below the antenna at the level of the ground at the signal output end, and establishing the Z axis at right angles to the M axis in the vertical direction of the signal output end;

[0039] Set the coordinates of the antenna endpoint at the signal output end to P3 (m1, z1), set the required transmission angle to δ, and according to the tangent function Calculate the vertical rotation angle θ of the signal output end, where θ = |δ-σ1|;

[0040] Set the coordinates of the antenna endpoint of the signal receiving end to P4 (m2, z2), according to the tangent function Calculate the vertical rotation angle θ of the signal receiving end, θ=|δ-σ2|.

[0044] While excluding the frequency of the frequency data set, the spectrum required to meet the device expansion range is set, and the data communication operation is completed according to the adjusted spectrum.

[0045] Furthermore, the spectrum required to meet the device expansion range is set, specifically:

[0046] Set frequency, compare the set frequency with the data of the frequency data set, and satisfy the condition that the set frequency does not belong to the frequency data set;

[0047] Set the amplitude and adjust the change according to the curve graph under the set frequency so that the curve after adjusting the amplitude does not intersect with any curve in the frequency curve graph;

[0048] The bandwidth is set, and after the above conditions are met, the transmission curve is distinguished from other curves, and the curve is denoised and smoothed to obtain the required spectrum.

[0049] A second aspect of the present invention provides a working method of an anti-interference communication system for power monitoring, comprising the following steps:

[0050] Obtain and pre-process the operating data of the monitored power system;

[0051] Encrypt the pre-processed and transmitted data, and perform security authentication on each terminal that accesses the data;

[0053] Receive the preprocessed data, use analysis operations to detect interference data within the transmission band, obtain the required extended spectrum through screening, transmit the instructions of the extended spectrum to the synthesizer for control, and use the spectrum adjustment operation to achieve anti-interference.

[0054] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0055] 1. The anti-interference communication system uses an adaptive adjustment module to receive pre-processed data for analysis operations, detects interference data within the transmission band, and screens to obtain the required extended spectrum. The command is transmitted to the synthesizer to control the spectrum adjustment operation, so that real-time collection of other spectrum affecting the transmission band can be realized, and then the frequency affecting the spectrum can be distinguished to realize adaptive frequency hopping operation, improve the anti-interference of signal transmission, and make the communication system more efficient and of better quality.

[0056] 2. Through the communication security authentication module, the first security authentication operation is completed by inputting the key. After the key matching is completed, the second security authentication operation is realized through face recognition by the signal receiving end processor. If the match is not performed within the threshold time or the match is wrong, the decryption operation cannot be completed. Otherwise, the decompression receiving operation is realized. This can also improve the anti-interference ability of the communication system, and effectively complete the security of the data transmission process, realize the real-name authentication, and reduce the probability of successful interception and access.

[0057] 3. Through the antenna intelligent control module, the antenna transmission direction of the signal output end and the signal receiving end is determined, and the antenna transmission direction of the signal output end and the signal receiving end is adjusted to keep the transmission direction relative. The top position of the antenna at the signal output end and the signal receiving end is determined, and the antenna angle is calculated and adjusted according to the set angle, so as to ensure the relative operation of signal transmission, and transmit based on the appropriate angle, improve the signal degree of signal transmission, and reduce the interference caused by its own factors.
