Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic signal leakage, and in particular to a video electromagnetic leakage signal protection system based on big data. Background Art

[0002] Electromagnetic leakage refers to the electromagnetic leakage caused by the equipment of the information system being able to radiate through the ground wire, power wire, signal wire, parasitic electromagnetic signals or harmonics when working. If these electromagnetic signals are received and extracted and processed, the original information can be restored, resulting in information leakage;

[0003] At present, the countermeasures for electromagnetic leakage are not discovered until a long time after the leakage, which causes the leakage of electromagnetic signals to threaten the security of information. After the leakage, people need to inspect every part of the equipment, which takes a lot of time. Therefore, we propose a video electromagnetic leakage signal protection system based on big data. Summary of the invention

[0004] The purpose of the present invention is to provide a video electromagnetic leakage signal protection system based on big data.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A video electromagnetic leakage signal protection system based on big data, comprising an acquisition unit, an identification unit, a database, a trajectory analysis unit, a signal detection unit, a protection unit and an intelligent device;

[0007] The acquisition unit collects electromagnetic information related to the video electromagnetic leakage signal and transmits the electromagnetic information to the recognition unit;

[0008] The database stores recorded information related to electromagnetic leakage in the video. The recognition unit obtains the recorded information from the database and performs recognition operations on the recorded information together with the electromagnetic information to obtain type data, recorded wavelength data, recorded power data, recorded position data, electromagnetic wave velocity data, electromagnetic frequency data, current data and voltage data, and transmits them together to the trajectory analysis unit;

[0009] The signal detection unit detects the signal outside the set distance range of the device, and the trajectory analysis unit performs trajectory analysis operation on the type data, recorded wavelength data, recorded power data, recorded position data, electromagnetic wave speed data, electromagnetic frequency data, name data, current data and voltage data to obtain leakage source data and leakage location data, and transmit them to the smart device;

[0010] receiving and displaying leakage source data and leakage location data through the smart device, generating a protection signal, and sending the protection signal, leakage source data and leakage location data to the protection unit;

[0011] The database also stores a leakage signal protection method corresponding to the name data. The protection signal is received through the protection unit, and the corresponding leakage prevention plan is extracted from the database according to the leakage source data and the leakage location data, and the corresponding leakage prevention plan is executed.

[0012] As a further improvement of the present invention: the specific operation process of the identification operation is:

[0013] Step 1: Acquire electromagnetic information, calibrate the fluctuation speed of the electromagnetic wave in the electromagnetic information as electromagnetic wave speed data, calibrate the frequency of the electromagnetic wave in the electromagnetic information as electromagnetic frequency data, calibrate the current size of the electromagnetic device in the electromagnetic information as current data, and calibrate the voltage size of the electromagnetic device in the electromagnetic information as voltage data;

[0015] Step 3: extract the recorded frequency data and the frequency data, and match them. When the matching results of the recorded frequency data and the frequency data are consistent, it is determined that the two are the same electromagnetic wave, and the type data corresponding to the recorded frequency data is automatically extracted. When the matching results of the recorded frequency data and the frequency data are inconsistent, it is determined that the two are not the same electromagnetic wave, and the type data is not extracted;

[0016] Step 4: Extract the recording wavelength data, recording power data and recording position data corresponding to the type data.

[0021] K4: Obtain current data and voltage data, and substitute them into the calculation formula: power = current data * voltage data, substitute the power and recorded power data into the difference calculation formula, thereby calculating the power difference, setting a preset value of the power difference, and calibrating it as the power preset value, and comparing it with the power difference to obtain a power abnormality signal and a power normal signal;

[0022] K5: Acquire a normal wavelength signal, an abnormal wavelength signal, a normal power signal, and an abnormal power signal. When an abnormal wavelength signal and an abnormal power signal appear at the same time, the electromagnetic signal is determined to be wrong and an analysis signal is generated. Otherwise, the electromagnetic signal is determined to be normal and no analysis signal is generated. The electromagnetic signal is leak analyzed based on the analysis signal to obtain leakage source data and leakage location data.

[0023] K6: Transmit leak source data and leak location data to smart devices.

[0024] As a further improvement of the present invention, the process of comparing the wavelength difference with the wavelength preset value is specifically as follows:

[0025] S1: When the wavelength difference is less than or equal to the wavelength preset value, it is determined that the wavelength change is within the preset value range, and a wavelength normal signal is generated;

[0026] S2: When the wavelength difference is greater than the wavelength preset value, it is determined that the wavelength change is outside the preset value range and a wavelength abnormality signal is generated.

[0027] As a further improvement of the present invention, the process of comparing the preset power value with the power difference value is specifically as follows:

[0028] A1: When the power difference is less than or equal to the preset power value, it is determined that the power change is within the preset value range, and a power normal signal is generated;

[0029] A2: When the power difference is greater than the preset power value, it is determined that the power change is outside the preset value range and a power abnormality signal is generated.

[0030] As a further improvement of the present invention, the leakage analysis process of the electromagnetic signal is specifically as follows:

[0031] H1: Obtain the corresponding record location data according to the type data;

[0032] H2: Obtain the recorded position data, and establish a virtual space rectangular coordinate system based on the bottom angle of the device corresponding to the recorded position data as the origin, calibrate the positions of different parts in the virtual space rectangular coordinate system, and record the calibrated points as part coordinate points;

[0033] H3: Obtain the position of the signal at different time points through the signal detection unit, and mark it as signal position data, mark the signal position data in the virtual space rectangular coordinate system, and mark the point as the signal coordinate point;

[0034] H4: Obtain the signal coordinate points of the signals detected at two different time points, connect the two signal coordinate points with a straight line, mark the straight line as the signal connection line, extend one side of the signal connection line, and when the part coordinate point is on the extended signal connection line, it is determined that the part is a signal leakage part and a danger signal is generated. When the part coordinate point is not on the extended signal connection line, it is determined that the part is not a signal leakage part and a re-detection signal is generated;

[0035] H5: Extract the danger signal and the re-detection signal, and identify them. When the re-detection signal is identified, perform the above H4 operation again. When the danger signal is identified, extract the corresponding name data and the corresponding record position data, mark the name data as the leakage source data, and mark the record position data corresponding to the leakage source data as the leakage position data.
