Elevator person retention detection method and elevator device

Abstract

The invention discloses a detection method for judging long-time staying of passengers in a lift car and used for an elevator. The method comprises the steps that from elevator door opening moment, information begins to be collected through an elevator standard sensor and other positions; and through integrated processing of the collected information, whether the elevator is in the long-term retention abnormal state or not is judged, and according to the long-term retention time, a corresponding execution mechanism of the elevator is controlled to do in-time response or give an alarm remotely. According to the technical scheme, the possibly-appearing risk that the person falls in a faint and is trapped in a household lift car is reduced, through detection of the condition that the passengers stay in the lift car for a long time, when long-term retention appears, the door is opened in time for alarm giving, and generation of the risk can be effectively avoided; and meanwhile, a sensor and an infrared detection device which are commonly used by an elevator device are used for detecting whether the person is in the elevator or not, a camera is not adopted, the privacy condition of the household elevator user is protected, and cost is reduced.

Description

technical field [0001] The invention relates to the field of elevator systems, in particular to a method for detecting the retention of elevator personnel and elevator equipment. Background technique [0002] Existing elevators arranged in public places have frequent people coming in and out, and no special countermeasures will be taken if people are detected in the car for a long time; while people staying in the home elevator for a long time is abnormal, and people may have fainted or pets have been killed. sleepy etc. [0003] Home elevators are elevators used by a single family, and there are often scenes where one person uses the elevator at home alone. Due to the privacy of the scene, the risk of people fainting and being trapped in the car is much greater than that of commercial elevators. At present, for the monitoring and detection of the internal situation of the elevator car, people in the industry still mainly use the camera to realize it. This solution fails t...

Problems solved by technology

At present, for the monitoring and detection of the interior of the elevator car, people in the industry still mainly use cameras to achieve this. This solution fails to take into account the privacy needs of passengers, so it is not suitable for use in home elevators
