A telemaintenance system that transmits real-time elevator operational data, fault codes, and status information to a remote monitoring centre via GSM, Ethernet, or IoT network.
Full Definition
Elevator remote diagnostics (telemaintenance) systems connect the elevator controller to a remote operations centre via a communication gateway. Data transmitted typically includes: current operational state, fault log with time-stamps, door cycle counts, starts per hour, motor temperature, safety device status, and trapped-passenger alarms. Communication paths include GSM/4G modem, Ethernet/LAN, or dedicated IoT protocols (MQTT, OPC-UA). EN 81-28 governs remote alarms for passenger evacuation; EN 81-82 addresses modernisation with telemaintenance. Remote diagnostics enables predictive maintenance by identifying fault patterns before complete failure, reduces physical inspection frequency, and provides legally required trapped-passenger communication per EN 81-28 clause 5.3. Data security requires encrypted communication (TLS 1.2 or higher) and role-based access control to prevent unauthorised elevator operation.
