[0005] In the prior art, devices for applying audio interference are generally installed at direct sound leakage places such as doors, windows, walls, and floors, and vibration jammers are installed at indirect sound leakage places such as pipes. The settings of these audio interference devices and vibration jammers are independent of each other, and the location of these devices is not easy to touch, so the operation status of these devices does not allow users to know

The invention relates to a sound masking system with a monitoring center. The sound masking system comprises a plurality of audio interference units and a plurality of vibration interference units. The audio interference units and the vibration interference units are respectively connected with a central control center. The central control center comprises a central processing unit, a query order sending module, a feedback signal receiving module, a feedback signal analyzing module and a display screen, and the query order sending module, the feedback signal receiving module, the feedback signal analyzing module and the display screen are respectively connected to the central processing unit. The central processing unit sends a detection order to the audio interference units and the vibration interference units through the query order sending module and receives feedback signals of the audio interference units and the vibration interference units. For the audio interference units and the vibration interference units installed at different corners and high positions, the fault of the audio interference units and the vibration interference units can be maintained conveniently and the device can be replaced through the sound masking system.
Description
【Technical field】 [0001] The invention relates to the technical field of eavesdropping prevention, in particular to a sound masking system with a monitoring center. 【Background technique】 [0002] With the continuous development of science and technology, eavesdropping techniques are becoming more and more diverse, such as telephone eavesdropping, microwave eavesdropping, laser eavesdropping, data eavesdropping, directional microphone eavesdropping, pipeline eavesdropping, etc. Aiming at various eavesdropping techniques, there are various means of preventing eavesdropping. [0003] At present, sound information protection for closed places (meeting rooms, offices, etc.) is mainly realized by building sound insulation structures, but the sound insulation method is limited by factors such as cost and engineering technology level, and it is far from preventing private Protection requirements for information leakage through sound channels. [0004] According to different mecha...
