Problems solved by technology

In recent years, injuries caused by the accidental movement of the elevator car have occurred from time to time. It is very dangerous for the elevator to move accidentally when the door is opened in the leveling area.
Shearing accidents can easily occur if the elevator moves unexpectedly before passengers are ready to step into the car

Embodiment 1

[0020] figure 1 It is a flow chart of the detection method for the unexpected movement of the elevator car provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of detecting whether the elevator car is moved unexpectedly. device, which can be integrated into a computer or other equipment.

[0021] In view of the gradual increase in the accident rate caused by the accidental movement of the elevator car, the country promptly issued the No. 1 amendment to the safety standard GB7588-2003 for elevator manufacturing and installation. This standard requires that the leveling and re-leveling control of the elevator with the door open should check the accidental movement of the car, and lock the elevator to prohibit it from running. The GB7588-2003 Amendment No. 1 clearly stipulates the stopping distance for the accidental movement of the car. From the time when the car accidentally moves away from the leveling position to the stop, the tot...

Embodiment 2

[0030] figure 2 It is a structural schematic diagram of a detection device for unexpected movement of an elevator car provided in Embodiment 2 of the present invention. The device can implement any detection method for unexpected movement of an elevator car provided in the embodiment of the present invention. The device can be integrated into a computer and other equipment . The device specifically includes: a feedback signal detection module 210 , a first time statistics module 220 and an unexpected movement determination module 230 .

[0031]The feedback signal detection module 210 is used to monitor the status feedback signal of the elevator, and determine the working state of the elevator according to the status feedback signal;

[0032] The first time statistics module 220 is used to count the duration of the suspected fault state when the elevator is in the suspected fault state, wherein the suspected fault state is to confirm the elevator hall door and the car door ac...

Abstract

The embodiment of the invention discloses an elevator car accidental movement detection method and device, equipment and a storage medium. The method comprises the following steps that a condition feedback signal of an elevator is monitored, and the working state of the elevator is determined according to the condition feedback signal; and when the elevator is in a suspected fault state, the duration of the suspected fault state is recorded, wherein the suspected fault state is that a elevator landing door and a car door are determined to be in an open state according to the condition feedbacksignal, and an elevator car is not in a door region; and if the duration time of the suspected fault state exceeds a first set threshold value, it is determined that the elevator car is accidentallymoved. According to the embodiment, the working state of the elevator is determined by monitoring the condition feedback signal of the elevator, and when the duration time of the elevator in the suspected fault state exceeds the set threshold value, the elevator car is determined to be accidentally moved, the response time of an accident is shortened, the safety of the elevator is improved, and injury accidents are avoided.

Description

technical field [0001] The embodiments of the present invention relate to the field of elevator control, in particular to a method, device, equipment and storage medium for detecting unexpected movement of an elevator car. Background technique [0002] With the continuous development of the economy and society, high-rise buildings, even super high-rise buildings, have generally existed in people's work and living places, and elevators have become an indispensable lifting tool for people. How to improve the convenience of elevator use and how to ensure the safety of people using elevators is a problem that major elevator manufacturers and technicians are always concerned about. In recent years, injuries caused by the accidental movement of the elevator car have occurred from time to time. It is very dangerous for the elevator to move accidentally when the door is opened in the leveling area. Shearing accidents can easily occur if the elevator moves unexpectedly before passen...
