Embodiment

[0042] This embodiment: as figure 1 As shown, a method for shielding interference information in secret-related areas, including:

[0043] Modulate the scanning signal into the interference base frequency S101 corresponding to the downlink frequency of CDMA, GSM and PHS through voltage-controlled oscillation;

[0044] The interference base frequency is amplified by power to form a frequency sweep signal, which is transmitted into the air in the form of radio waves from low frequency to high frequency and then scanned S102;

[0045] If the sweeping signal acts on the power range S103, the power range is in a no-network state S104;

[0046] If the sweeping signal disappears S105, return to the normal state S106.

[0047]Because the scanning signal is modulated by voltage-controlled oscillation to the interference base frequency corresponding to the downlink frequency of CDMA, GSM and PHS; the interference base frequency is amplified by power to form a frequency scanning signal...

Abstract

The invention belongs to the technical field of information security, and particularly relates to an interference information shielding method for a secret-involved area. The invention simultaneouslyprovides an interference information shielding system for the secret-involved area. The method includes the following steps: respectively modulating scanning signals into interference fundamental frequencies corresponding to CDMA, GSM and PHS downlink frequencies through voltage-controlled oscillation, performing power amplification on the interference fundamental frequencies to form swept-frequency signals, and sequentially and respectively transmitting and scanning the swept-frequency signals into the air from low frequency to high frequency in the form of radio waves. According to the scheme of the invention, the problem that the influence of electromagnetic radiation on the human body is caused due to high electromagnetic radiation and high power in the prior art can be solved, and thebeneficial technical effects of reducing the influence of the electromagnetic radiation on the human body, reducing the power consumption of a shielding device, preventing interference with other electrical equipment and realizing the purpose of environmental protection shielding can be achieved.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to an interference information shielding method used in secret-related areas. The invention also provides an interference information shielding system used in secret-related areas. Background technique [0002] When the mobile phone is working, it is within a certain frequency range. The mobile phone and the base station are connected by radio waves, and the transmission of data and sound is completed with a certain baud rate and modulation method. According to this communication principle, the mobile phone signal jammer is in the working process. Scan at a certain speed from the low-end frequency to the high-end of the forward channel. This scanning speed can cause garbled code interference in the received message signal of the mobile phone. The mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a...
