Abstract: An indication box used with an electronic smart lock indicates if a public service room is in use. A color plate partially shown in a window moves vertically up and down with door handle motion. Unlike other indicators, the door handle and not lock actives use indication to avoid mishaps from forgetting to lock the door. The color plate is spring loaded with a V-shaped bottom. The color plate vertically moves by a cam having two L-shaped portions forming a V-shaped recess to initially secure the color plate's V-shaped bottom. Cam activation is through a dial head that moves with the door handle. When the color plate indicates use, the V-Shaped bottom rests on one of the cam's L-shaped portions. The color plate may also include braille markings. The indication box is used on a door's front portion with any electronic smart lock design and operates without electrical power.

Abstract: The present invention relates to the technical field of intelligent locks, and particularly to an intelligent lock management system, comprising an intelligent lock unit, wherein the intelligent lock unit comprises an intelligent lock, a lock control module and an identification terminal, and the intelligent lock unit is used for controlling the usage states of the intelligent lock; a server unit, wherein the server unit is communicatively connected with the intelligent lock unit, and the server unit is used for processing the receiving and sending of user information and control information. The server unit comprises an information writing module, a permission management module, an information deletion module and a data recording module. The permission management module is used for classifying and managing user permission data, and the user permission levels are at least 2. In the present invention, the permission management of the lock is divided into at least two levels.
