Description

technical field [0001] The invention relates to the electromagnetic field, in particular to an intelligent electromagnetic degaussing system and method based on target recognition. Background technique [0002] The destruction of magnetic carriers is the last link in the secrecy management of state secret carriers. The main magnetic carriers include magnetic storage media such as hard disks, magnetic tapes, and floppy disks. Electromagnetic degaussing machine is a degaussing technology that uses a strong magnetic field to destroy the information in the magnetic storage medium, that is, by injecting a strong instantaneous current into the electromagnetic coil, a super strong magnetic field is generated in the center of the electromagnetic coil, so that the magnetic storage placed inside the electromagnetic coil Media degaussing, which is a technical means to completely destroy information. [0003] In order to ensure the effect of electromagnetic degaussing, the electromagne...

AI Technical Summary

Problems solved by technology

The strong current will generate high voltage at both ends of the coil, which may affect other electrical equipment when using the degausser in an office environment

In addition, for magnetic media of different materials and sizes, the magnetic field strength required to achieve complete degaussing is different, and with the development of technology, the types of magnetic media are also increasing, which brings new challenges to the use and upgrade of electromagnetic degaussing machines. difficulty

If in order to achieve the degaussing effect, simply using the maximum power of the degaussing machine will cause a great waste of electric energy and shorten the service life of the degaussing machine
