Problems solved by technology

Most of the current elevators are controlled by PLC. Once the PLC device is damaged, it will take a lot of time for the elevator to operate again. When some criminals destroy the elevator, they often destroy the fragile PLC controller. A device that is not damaged can solve these problems, so it is very beneficial to design a protective shell for the elevator PLC device

Abstract

The invention relates to a protecting shell for an elevator PLC (programmable logic controller) device. The protecting shell comprises a shell body (10), and the opening of the shell body (10) is downwards; the opening is provided with an outer turning edge (101), and the positive face of the shell body (10) is provided with a visible acrylic plate (102), a sound alarm (106) and a data exchange port cover plate (107); the top part of the shell body (10) is embedded with a magnetic card sensing device (103), a strip-shaped flash lamp (104) and a level gauge sensor (109); the side face of the shell body (10) is provided with a strip-shaped radiating hole (105) and a signal emitting antenna (108). The protecting shell is simple in structure and convenient to use; the shell body covers on the PLC device, the cover shell or the data exchange port cover plate can be safely opened only when a person with the magnetic card contacts the magnetic card sensing device by the magnetic card, so as to prevent the PLC device of the elevator from being damaged and destroyed; and thereby, the normal operation of the elevator is guaranteed.

Description

[0001] Technical field: [0002] The invention relates to the field of elevator devices, and more specifically relates to a protective shell of an elevator PLC device. [0003] Background technique: [0004] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regardless of its driving mode. Most of the current elevators are controlled by...
