Problems solved by technology

[0005] The existing elevator system needs to combine the operating status of the elevator itself to obtain whether the elevator is faulty. At present, the acceleration sensor has been applied to the elevator system, realizing various elevator fault detection and speed detection, etc., and improving the elevator running function detection. During actual operation, various parameters based on the time relationship are subject to change. For example, the acceleration value and speed value are all changing at any time. How to realize the detection and implementation of the trapped persons based on the acceleration sensor is currently not given. come up with a way of combining and coping

[0080] specific, figure 2 The method of the present invention shows a state of the elevator car is detected in the embodiment of the embodiment of the flowchart of the first embodiment, comprising the steps of:

[0081] S101, obtaining a vertical acceleration in the vertical direction on the elevator car every time horizontal acceleration value Ay and the car door moving horizontally values ​​Ax, Ay and Ax, and stores the value in a time series based on the acceleration sensor;

[0082] The multi-axis acceleration sensor is fixed to the movable door of the elevator car, in this example embodiment of the multi-axis acceleration sensor mounted on the z-axis perpendicular to the door leaf, x-axis is parallel to the direction of the movable leaf, parallel to the y-axis perpendicular to the ground of the elevator hoistway. Analyzing the running direction of the elevator is an elevator up to the numerical determination of the acceleration sensor when the elevator is moving down operatio...

Abstract

The embodiment of the present invention discloses a detection method for abnormally trapped persons in an elevator car. An acceleration sensor is arranged on the moving car door of the elevator car, and a PIR sensor is arranged inside the elevator car. The method includes : Based on the PIR sensor to record the personnel information in and out of the elevator car; based on the acceleration sensor to obtain the running state of the elevator car; when the acceleration sensor judges that the running state of the elevator car is abnormal, based on the The personnel information recorded by the PIR sensor judges whether there are personnel trapped. In the embodiment of the present invention, low-cost PIR sensors and acceleration sensors can be used to detect people being trapped, and there is no need to rewire and modify the electrical structure of the existing elevator control system, and the existing acceleration sensor is optimized. It can only realize the fault detection behavior of elevators, and it can realize the detection function of people trapped in a deeper level.

Description

Technical field [0001] Technical Field The present invention relates to an elevator, and particularly to a method and a system for detecting the elevator car of the abnormality trapped. Background technique [0002] With the development of society, elevator increasingly popular as a means of transport to people's lives, the quality of personnel passengers, passengers increasingly wide range of elevator failures, power outages foreign passengers trapped elevator passengers fainting as a result of the phenomenon there also happen when. [0003] After today's elevator entrapment by the police are often trapped in self-call or triggering an emergency alarm device to achieve inside the elevator car, which is often not timely rescue issues within the phone no signal or the car rescue device failure due to appear for a conditional where the installation of cameras is mainly through direct person to see if someone in the car, which gives relief and regulators brought great inconvenience,...
