Description

Elevator light curtain

Technical Field

The utility model belongs to the technical field of elevators, and particularly relates to an elevator light curtain.

Background

The elevator light curtain is a light ray type safety protection device for elevator door, and is suitable for passenger elevator and goods elevator to protect the safety of passengers. The elevator car consists of four parts, namely an infrared transmitter and an infrared receiver which are arranged on two sides of a car door of an elevator, a power box arranged on the top of the car and a special flexible cable. 32 (16) infrared transmitting tubes are arranged in the transmitter, and the transmitting and receiving tubes are sequentially opened under the control of the MCU to continuously scan the car door area from top to bottom to form a dense infrared protection light curtain. When any beam of light is blocked, the control system immediately outputs a door opening signal, the car door stops closing and rotates reversely to open until the elevator door can be normally closed after the passenger or the blocking object leaves the warning area, so that the safety protection purpose is achieved, and the occurrence of accidents caused by people being in the elevator can be avoided.

An antenna is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space) or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all use electromagnetic waves to transmit information and work by depending on antennas. In a radio device, a device for radiating and receiving radio waves is called an antenna. The antenna provides the required coupling between the transmitter or receiver and the medium through which the radio waves propagate. The antenna, as well as the transmitter and receiver, are also an important component of the radio device.

In the elevator light curtain in the prior art, because the section bar of packing the light curtain is mostly the metal material, so the antenna is installed in the elevator light curtain, and the signal quality of transmission is very poor.

SUMMERY OF THE UTILITY MODEL

In order to achieve the purpose, the utility model adopts the following technical scheme: an elevator light curtain comprising: the antenna comprises a section bar, a plug, a power line and antenna equipment; one end of the plug is connected with a power line and antenna equipment, the other end of the plug is connected with the section bar, and the antenna equipment and the power line are arranged side by side;

and the antenna wire core of the antenna equipment is connected with the connector arranged on the PCB in the section bar.

Further, in the elevator light curtain, the power line, the antenna device and the plug are integrally cast.

Further, in the elevator light curtain, the plug and the section bar are connected and fixed in an opposite insertion mode.

According to the utility model, the antenna equipment is arranged outside and fixed on the plug, and the antenna wire core penetrates through the PCB connected to the section bar, so that the problem that the signal of the antenna arranged in the section bar is weak is solved, and the problem that the antenna is cut by burrs caused by machining the section bar when the antenna is directly fixed with the section bar is also solved.
