Description

technical field [0001] The invention relates to an intelligent safety management device, in particular to an intelligent key cabinet device. Background technique [0002] At present, there are generally several schemes for the management of small items such as keys at home and abroad: Scheme 1: Manual service. Adopt the management mode of special personnel to keep and issue keys. This manual service method is more traditional and backward. The disadvantage is that it wastes a lot of human and financial resources, and it is inefficient and cannot realize real-time backtracking management of keys. Option two: supermarket-style storage cabinets. Controlled by a single-chip microcomputer, using VB programming, the programming is complicated, and it is troublesome to upgrade the machine. Use barcode scanning to access items. The advantage of the supermarket style is that it is self-service, eliminating the need for manual care of keys. The disadvantage is that it is impossi...
