Problems solved by technology

There are also various cultural relic warehouse doors and treasury doors. For example, cultural relic warehouse doors and treasury doors are divided into C grade, B grade, A grade and M grade. C grade is the highest grade. The higher the grade, the better the anti-theft protection performance; however At present, the design of the lock body of the cultural relics warehouse door and the treasury door is relatively simple. The biggest drawback is that the warehouse managers cannot close the cultural relics warehouse door or the treasury door when they enter the warehouse to work. Some products just add an ordinary fence door for protection. , its protective ability is far from enough for the safety of personnel, precious cultural relics and national property in the warehouse, and it is easy to be used by criminals to cause robbery and robbery, which will cause losses to the country and personal safety.
