Embodiment 1

[0053] see figure 1 , this embodiment provides a remote rescue system for people trapped in an elevator under specific circumstances, and the system is used for remotely rescuing people trapped in an elevator. The elevator can be an existing elevator. In this embodiment, the elevator includes a car, a brake release device and a solenoid valve. The car is the main part of the elevator, which plays a load-bearing role. Generally speaking, the car is provided with an emergency alarm phone or an emergency alarm button, and when a person is trapped in the car, it can send a rescue signal through the phone or button. The brake release device is used to loosen or lock the brake of the car, and it can adopt the existing elevator brake release device, which cooperates with the brake to brake the car when the car needs to stop at the corresponding landing. The solenoid valve is used to drive the brake release device to loosen or brake, and can realize the control function of the brake...

Embodiment 2

[0078] This embodiment provides a remote rescue system for people trapped in an elevator under specific circumstances, and the system adds a specific help-seeking sign on the basis of Embodiment 1. There is at least one specific help sign, and it is installed in the car. Specifically, the specific help sign can be directly pasted on the inner wall of the car, or integrally formed with the car, or installed on the inner wall of the car through connecting parts such as bolts. The specific help-seeking sign provides at least one kind of picture of a person's help-seeking action, and the picture of the person's help-seeking action is used to prompt the trapped person to perform a corresponding help-seeking action. The control device is also used to first obtain the outline of each person according to the real-time image, and then judge whether the similarity between the outline of each person and the contours of various help-seeking actions in a preset help-seeking information dat...

Embodiment 3

[0081] This embodiment provides a remote rescue system for people trapped in an elevator under certain circumstances, and the system adds a speed measurement module on the basis of Embodiment 1 or Embodiment 2. The speed measuring module is installed on the car and is used to measure the moving speed of the car. The control device is also used to judge whether the moving speed exceeds a preset speed. When the moving speed exceeds the preset speed, the control device drives the brake releasing device to increase the brake tightening force through the solenoid valve. In this way, the control device can judge whether the speed measured by the speed measurement module exceeds the preset speed. If it is, it means that the car is rising or falling too fast. Safe and smooth ascent or descent to the leveling area.

Abstract

The invention discloses a remote rescue system and method for people trapped in an elevator under a specific condition and the elevator. The system comprises a camera, a leveling sensor and a controldevice; the camera is installed in a lift car of the elevator and used for shooting real-time images located in the lift car; the leveling sensor is installed in a leveling area of the elevator and generates a leveling signal when the lift car arrives at the leveling area; the control device is used for processing the real-time image, comparing the real-time image with a dangerous state contour, calculating contour similarity, judging whether the contour similarity reaches a preset similarity or not, and if so, sending a rescue signal to a remote control platform; the control device further drives a brake releasing device to release, so that the lift car ascends or descends to the leveling area to drive the brake releasing device to brake tightly, and rescue information is sent to an elevator management center. According to the remote rescue system and the method for people trapped in the elevator under the specific condition and the elevator, rescue can be more timely and accurate, the safety of people taking the elevator is guaranteed, the rescue efficiency can also be greatly improved, secondary damage is avoided, and precious rescue time is won.

Description

technical field [0001] The present invention relates to a remote rescue system in the technical field of elevators, in particular to a remote rescue system for elevator trapped persons under specific circumstances, and also to a remote rescue method for elevator trapped persons under specific circumstances of the system, and also to a remote rescue system including elevator trapped persons under specific circumstances. An elevator with a remote rescue system for trapped persons. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. As a common transportation equipment, the elevator is used very frequently, so the possibility of its failure is relatively high. Under normal circumstances, when an elevator breaks down, that is, after rec...
