The deployment of local computing resources within or adjacent to an elevator installation to process sensor data, run predictive algorithms, and enable real-time decisions without relying solely on cloud connectivity.

Edge computing brings computational intelligence directly to the elevator controller or a dedicated edge gateway installed in the machine room. Instead of sending all sensor data to a cloud platform for analysis, an edge device processes data locally — enabling millisecond-response fault detection, predictive maintenance alerts, and local AI inference even during network outages. Key elevator edge applications include: vibration signature analysis for bearing wear detection; door cycle performance trending; motor current signature analysis (MCSA) for winding degradation; and energy consumption optimisation per trip. Edge devices complement rather than replace cloud analytics: aggregated and filtered data is periodically uploaded for fleet-wide benchmarking and digital twin synchronisation. Industrial-grade edge hardware (IEC 61131-based PLCs or ARM-based gateways) must operate within the machine room thermal range (+5 to +40°C per EN 81-20). Cybersecurity of edge devices is governed by IEC 62443. Edge computing reduces bandwidth costs, latency, and cloud dependency, making it increasingly standard in smart elevator systems.
