Customer Background
The VF106 E-board at a university classroom door becomes the entry that links timetables, room resources, face lists, class sign-in/out, room-booking approval, device status and reports into one loop. It is not a single attendance project but a "smart classroom operations platform": it ensures attendance authenticity, lifts room utilization, eases scheduling/stats and seeds campus-space management data.
Pain Points
Attendance authenticity. QR/card are easy to proxy; paper roll-call is heavy and untraceable.
Idle room resources. Capacity, groups, owners, timetables and bookings are scattered; idle rooms hard to allocate.
Devices unmanaged after install. Boards lack online/offline/sync records; faults need manual per-device checks.
High launch threshold. Schools fear they must open the academic API to start, making launch hard.
DejaOS Solution
Base data center. Term, periods, timetable, people, rooms, room groups, capacity, owners, device SN for unified timetable/linkage caliber.
Timetable management. Courses by term/week/day/period/room/teacher, template import and multi-week batches, forming room and teacher weekly schedules.
Face list & rights sync. After importing people/faces, sync to boards by course/room/group, recording action/status/failure/receipt.
Class sign-in/out. Students face-recognize at the board; system records sign-in/out time/status by course/room/role for attendance stats.
Room booking approval. Teachers submit by term/week/period/room; on approval a temp timetable syncs to devices, giving temporary use a credential.
Device status & alarm. MQTT keeps board online status, logs up/down/sync anomalies, supports O&M view and export.
Access extension. Existing passage and valid-time fields can link locks to control room use by timetable and approval.
Expected Business Value
Authentic attendance. Face sign-in cuts proxy/miss; data bound to course/teacher/room, fit for study style and teaching-process management.
Higher room utilization. Unified capacity/groups/owners/timetable/booking enables usage analysis and less idle space.
Manageable devices. Online/offline/sync records let O&M locate issues by room, avoiding "installed but unmanaged".
Low-threshold launch. Excel templates import timetable/people/rooms for pilot acceptance, then integrate academic/student/SSO; replicable to K-12, training, corporate centers and public training bases.
