Interconnected type full-band signal shielding device, system and method

Abstract

The invention relates to an interconnected type full-band signal shielding device, a system and a method. The interconnected type full-band signal shielding device includes a broadband radio-frequency power detection module, a microcontroller module, a DDS radio-frequency signal producing module, a modulation module and a broadband radio-frequency power amplification module. The broadband radio-frequency power detection module detects radio-frequency signal information of the surroundings and transmits the information to the microcontroller module. The microcontroller module controls the DDS radio-frequency signal producing module to produce baseband signals which are the same as radio-frequency signal information of the surroundings and transmits the baseband signals to the modulation module. The modulation module is used for producing specific interference signals modulating the specific interference signals into the baseband signals and transmitting the modulated baseband signals to the broadband radio-frequency power amplification module. The broadband radio-frequency power amplification module amplifies the power of the modulated baseband signals, and final shielding radio-frequency signals are formed. The interconnected type full-band signal shielding device, system and method solve the problems that intelligent level of the existing equipment is low and shielding function is singular and can be interconnected and shield full-band signals.

Description

technical field [0001] The invention relates to the field of signal shielding, in particular to an interconnected full-band signal shielding device, system and method. Background technique [0002] The shielding device is a signal shielding device, which is used as a signal shielding device for mobile phones or similar electromagnetic signal transmitters.

AI Technical Summary

Problems solved by technology

[0003] The existing signal shielding equipment has the following defects: 1. It can only shield radio frequency signals in specific frequency bands such as mobile phone signals, but cannot shield other radio frequency signals; 2. It does not have networking functions. etc. cannot be automatically controlled, and the device is turned on for a long time, which will lead to a short life of the device and affect other normal communications; 3. The interference source is single and cannot be set; some of the existing devices have power detection functions, but the frequency band is narrow, and because there is no interconnection, Therefore, radio frequency power detection needs to be scanned in a fixed frequency band every time, and all equipment cannot be mobilized to collect and share data in sections, resulting in waste of time and increased energy costs; 4. Since there is no interconnection, the data after power detection is wasteful, and Unable to locate; 5. The transmission power of the existing equipment is fixed, the shielding range is fixed, and the intensity of the interference source cannot be adjusted according to the shielding requirements; 6. The existing equipment does not have a server, so it cannot accurately perform big data calculation processing; 7. The equipment cannot be centrally controlled and counted , alarm, processing, does not have equipment and radio frequency information centralized processing capabilities, cannot share shielded data, and is inconvenient for information maintenance and management; 8. Most of the existing equipment is built with hardware, and there is no equipment upgrade interface, which is inconvenient for software upgrades and maintenance
