Description

Fireproof cabinet capable of automatically destroying high-confidential documents and automatic control system thereof

Technical Field

The invention belongs to the field of confidential document file cabinets, and particularly relates to a fireproof cabinet capable of automatically destroying high confidential documents and an automatic control system thereof.

Background

Filing cabinets, i.e. cabinets for keeping archival data or confidential documents, commonly referred to as covered boxes and cabinets with doors, are generally made of metal materials, and some of them are also made in a combined type, separated into boxes, stacked into cabinets, which have the advantages of effective dust prevention and theft deterrence. Modern filing cabinets are more versatile and are developed towards computer-controlled multifunctional filing cabinets.

Although the cabinet made of metal will not burn in fire, so that the file data or confidential documents will not be burnt, the file data or confidential documents in the cabinet will be damaged by the high temperature of the cabinet along with the rise of the temperature of the cabinet, which is not good for the storage of the file data or confidential documents. In addition, although the conventional file cabinet has a certain anti-theft function, when the file cabinet storing the high-level confidential documents (such as trade secrets, military secrets, etc.) faces a thief or even a group to be stolen, the risk of theft is still huge, and once the high-level confidential documents are stolen, the consequence is not obvious, and the file cabinet storing the high-level confidential documents needs a safer anti-theft means.
