2BBVA-KEYNIUSElectronic lock

Functional design battery lock (SLIM) This functional design describes the functionalities and scenario’s for the of Battery locks. There are two different Battery locks models: Pincode and RFID. Both types have Bluetooth to enable access for admin (managing lock) and for user (use).

Apply offline or online? If it is offline, it is easy. If it is online, how to deal with authorization, cabinet number, lock number association and so on will need to consider With flex use, the user can only apply physically on the battery lock itself (so offline) see 2.1.1.1 ）, store belongings and then close the locker. After opening the locker is again free to claim/use for everyone. Flex use (one time) is set as a default scenario (also after factory reset). 2.1.1 Pincode After pressing every button (number) all LED’s will blink WHITE for 1 second （2. Blink 1 second is a little long, 200ms is recommended, 1 second the user experience is not good） Agreed, let’s do 200 ms instead of 1 second. and a Beep is heard. Example: Press number 1 (all LED’s will blink WHITE for 1 second and Beep is heard), press number 2 (all LED’s will blink WHITE for 1 second and Beep is heard), etc. 2.1.1.1 Claim a locker - User approaches available locker (Battery lock is available when the point of the knob is rotated to either 9 o’clock or 3 o’clock. A graphical icon of an open lock is shown). - User stores his/her belongings in locker - User closes the lockerdoor - User fills in 4 digit pincode (1st time), and presses confirmation button(3. Is there a password length requirement? 4 to 8 digits or a fixed number of 4 digit) For users lets keep a fixed of 4 numbers, for admin it can be 6 After confirmation button, all LED’s will blink GREEN 1 time. - User fills in 4 digit pincode (2nd time), and…
