Design of the Non-intrusive Elevators Monitoring System for Terminals

In response to the special requirements for safe and efficient monitoring of elevator operations at domestic hub airport terminals, which vary by age and brand, a non-intrusive elevator operation monitoring system is proposed. By designing devices for collecting elevator operation status and controller bus data, the system achieves non-intrusive collection of signals related to car operation and faults. A method for multi-type protocol conversion and communication interface design is proposed, along with the provision of a unified interface standard, effectively addressing the barriers to collecting elevator signals from multiple manufacturers and the challenges of elevator internet integration. Practical operational testing of the system in real-world scenarios has demonstrated the validity of its monitoring data and the stability of its operation. This system is of great significance for improving the safety and reliability of IoT-based elevator monitoring in high-traffic, aging airport terminals.
