Elevator security and protection system and elevator thereof

Abstract

The invention discloses an elevator security and protection system. The elevator security and protection system comprises a password input device, an access control host, an electric lock, a detection device and a speed measurement device, wherein the password input device is used for manually inputting passwords so that the access control host can control the electric lock to be started; the access control host is used for controlling the electric lock to be started and shutdown; the electric lock is used for completing opening and closing of an elevator door ultimately; the detection device is used for starting the speed measurement device when an elevator descends after the elevator is closed; and the speed measurement device is used for detecting the descending speed of the elevator and further turning on an electric telescopic rod switch when the speed is too high. According to the elevator security and protection system, due to the fact that the elevator is used after password recognition, the phenomenon that outside people can use the elevator at will is prevented while normal use of the elevator by residents is ensured; the speed measurement device is used for detecting the descending speed of the elevator, when the speed is too high, the electric telescopic rod switch can be turned on, and an electric telescopic rod can push a damping plate and a damping bottom plate out of an installation box quickly; and when an elevator body falls onto the ground, the damping bottom plate can make contact with the ground, and the effect of damping protection can be achieved due to arrangement of a spring.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator security system, and also relates to an elevator. Background technique [0002] In the current residential buildings, the elevators are basically not equipped with access control systems. When the elevator is working normally, the car hall call board is always activated. Anyone can call the elevator through the car hall call board and use it. Like this just can't carry out effective safety management to floor, makes theft incident often take place, causes economic loss to owner. [0003] When the elevator stalls and lands and touches the ground, there is no safety structure, which can easily cause casualties. [0004] For this reason, we propose an elevator security system and its elevator to solve the problems mentioned in the above-mentioned background technology. Contents of the invention [0005] The object of the present invention is to provide ...
