Electric bicycle identification blocking early warning system for elevator

Abstract

The invention discloses an electric bicycle identification blocking early warning system for an elevator. The electric bicycle identification blocking early warning system comprises a control box connected with a power supply, a photoelectric switch connected with the power supply, a plurality of pressure sensors, a magnetic field sensor and a microwave transmitter, and the photoelectric switch, the pressure sensors, the magnetic field sensor and the microwave transmitter are electrically connected with the control box. From the structure, by utilizing the characteristic that an infrared receiver is prone to being interfered by radio frequency radiation signals such as microwaves and then loses efficacy, when an electric bicycle goes in and out of the elevator, the electric bicycle identification blocking early warning system for the elevator directly interferes the infrared receiver arranged on the elevator through the microwave transmitter to make an elevator door be kept in an opened state after simultaneously receiving a pressure signal of the electric bicycle and a magnetic field signal of a driving motor of the electric bicycle.

Description

technical field [0001] The invention relates to the technical field of elevator identification and early warning, in particular to an electric bicycle identification and early warning system for elevator elevators. 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. Traction system: The main function of the traction system is to output and transmit power to make the elevator run. The traction system is mainly composed of traction machine, traction wire rope, guide wheel and anti-rope pulley. [0003] Elevators generally include a guide system, a car, a door system, a weight balance system, an in-store drag system, an electrical control system, and a safety protection system. [0004] Electric bicycles are the most popular means of ...

AI Technical Summary

Problems solved by technology

However, if the electric vehicle is charged in the building, once a short circuit occurs, it will cause a fire, and the consequences will be very serious.

Moreover, it will be more troublesome to push the electric bicycle into the elevator, especially when there are already people in the car, resulting in a longer time for the electric bicycle to be pushed into the elevator

Although the elevator is generally designed with an automatic door closing time during the design process, when the car door of the elevator is opened for a period of time, the car door of the elevator will automatically close, which causes the elevator car door to clamp the electric bicycle, As a result, the relevant parts of the elevator car door are deformed, which affects normal use, and even causes some parts to be damaged and cannot be used directly.

There is also currently no effective way to prevent e-bikes from entering elevators

Moreover, the cost of transforming the elevators of high-rise residential buildings is extremely high, and even because the structure of the elevator shaft has been fixed, it is impossible to transform the elevators.
