However, the problem of cultural relic security is becoming increasingly serious, and traditional security means are no longer sufficient to meet the needs. At present, the anti-theft of cultural relics mainly relies on manual inspections and static monitoring, which has many drawbacks. Manual inspections have limitations in time and space, and it is easy to have blank periods and areas of supervision, and the labor cost is relatively high. Static monitoring can only record fixed images, and has insufficient perception of the real-time state of cultural relics, and cannot issue early warnings in time when cultural relics are threatened. In terms of cultural relic tracking, traditional methods are even more inadequate, and it is difficult to achieve accurate positioning and dynamic tracking of cultural relics. Once a cultural relic is stolen, it is extremely difficult to recover. At the same time, in the face of the development of the electronic information era, cultural relic security has not fully integrated intelligent security technologies, lacks the ability to efficiently process and analyze a large amount of security data, and it is difficult to form a comprehensive and intelligent cultural relic security system.
