AI Technical Summary
Existing technologies cannot effectively detect abnormal opening and closing of elevator doors, especially abnormalities such as foreign objects getting stuck in the door guide rail or sill, resulting in untimely fault detection.
An anomaly diagnosis device is adopted, which includes a door opening and closing sensor and anomaly diagnosis sensor. The signal processing unit analyzes the signal, extracts the diagnostic range, and diagnoses the door opening and closing anomalies. Specific sensors include magnetic sensors, illuminance sensors, photoelectric sensors, distance sensors, and cameras.
It can detect abnormal opening and closing of elevator doors at an early stage, prevent malfunctions, and improve the reliability and safety of elevator systems.
