Abstract: A safety net system is provided for an elevator system including an elevator pit and multiple points of ingress to the elevator pit. The safety net system includes multiple sensors arranged in multiple planes encompassing the multiple points of ingress to perform sensing and to generate data corresponding to sensing results and a processor coupled to the multiple sensors to analyze whether the data indicates a person entering the elevator pit and to take an action based on results of the analysis.

Abstract: A safety net system is provided for an elevator system that includes an elevator pit and a ladder adjacent to an elevator pit wall for accessing the elevator pit. The safety net system includes a sensor and a processor. The sensor is arranged in a plane between the ladder and the elevator pit wall and is configured to perform sensing to sense an object disposed along the plane and to generate data corresponding to results of the sensing. The processor is operably coupled to the sensor and is configured to analyze the data and to determine whether the data is indicative of a person standing on the ladder based on analysis results.

Abstract: An elevator system includes a hoistway; an elevator car configured to travel in the hoistway; a pit located at a bottom of the hoistway; a safety chain configured to enable or disable motion of the elevator car; and a sensor assembly configured to initiate opening the safety chain to disable motion of the elevator car upon detection of a person in the pit.

Abstract: A method of operating a safety net system of an elevator system is provided. The method includes installing a sensor in an elevator pit of the elevator system and executing a learning phase of the sensor to verify successful installation of the sensor. The executing of the learning phase includes causing the sensor to sense physical characteristics of a portion of the elevator pit when the elevator pit is known to have certain physical characteristics to generate a background reading, comparing the background reading against a reading associated with known physical characteristics of the portion of the elevator pit and verifying the successful installation of the sensor based on results of the comparing.
