Description

Optical communication device for elevator

The present invention relates to an optical communication device for an elevator, and more particularly, to an optical communication device for an elevator that shortens the optical communication distance to the shortest distance.

As more and more examples of installing a monitor for displaying information inside an elevator, specifically a door, a wall, or a ceiling, optical communication is increasingly adopted to transmit data to the monitor from the outside.

1 is a cross-sectional view of an elevator lift showing this optical communication method. For optical communication, an optical communication transmitter 140 is generally installed at the bottom of the hoistway, and an optical communication receiver 150 is installed at the bottom of the elevator E facing the optical communication transmitter. In this case, in general, data is transmitted through optical communication between the transmitter 140 and the receiver 150 while the elevator E reaches the lowest point as shown in the drawing, and such data is viewed by the passenger on the monitor M. It is usually displayed to be able to.

In this case, as shown in the drawing, the optical communication distance between the transmitter and the receiver is approximately one floor high or more than the average height of a general adult male, which causes a problem of low optical communication quality. The quality of optical communication is better the shorter the communication distance. In addition, since the transmitter is installed on the bottom of the hoistway, the transmitter is exposed to a relatively dirty environment, and dust or foreign matter accumulates on the surface of the transmitter. In particular, since the elevator hoisting movement is very frequent, there is a lot of foreign matter such as dust, so it is particularly severe that the transmitter surface is covered with foreign matter. In this case, optical communication will be disturbed, and data transmission will not be performed properly.

In addition, as shown in the figure, since the controller (C) including the computer installed in the machine room located at the upper end of the elevator elevator and the optical communication transmitter 140 must be connected with a wired cable, the length of the wired cable is inevitably long. Problems arise in terms of cable maintenance and costs.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems in the related art, and an object thereof is to maintain an optimum communication quality with the shortest optical communication distance.

The present invention also aims to place the optical communication transmitter and receiver in a relatively clean environment to prevent dust and foreign matter from interfering with the communication.

The present invention also aims to reduce installation and maintenance costs by minimizing the length of the wired cable connected to the optical communication receiver.

In order to achieve the object of the present invention, the present invention is a data transmitter 10 is installed on the wall or ceiling of the hall near the front of the elevator door;

A data receiver (30) installed behind a hall button cover (20) of a building elevator and wirelessly connected to the data transmitter (10) to receive digital data from the data transmitter;

An antenna 32 embedded in the hall button cover 20 and connected to the data receiver 30;

An optical communication transmitter 40 connected to the data receiver 30 by wire and installed on a wall of an elevator hoistway P for converting the digital data into optical data and transmitting the optical data;

When the elevator E stops for the passenger's boarding / unloading, the elevator E is installed at the elevator E at a position facing the optical communication transmitter 40 and receives data from the optical communication transmitter 40 by wireless optical communication. Optical communication receiver 50;

A controller (C) connected by wire to the optical communication receiver (50), installed on the ceiling of an elevator (E), and receiving data from the optical communication receiver (50) and converting the data into image data; And

It is connected to the controller (C) by wire, and installed on the door, wall or ceiling of the elevator (E), monitor (M) for receiving the image data from the controller; provides an optical communication device for an elevator comprising a.

In the optical communication device of the present invention, the data transmitter 10 may transmit data using LTE, WiFi, or wireless LAN.

In addition, it is preferable that the optical communication transmitter 40 and the optical communication receiver 50 be spaced apart by the distance between the hall door D1 and the cage door D2 of the elevator E.

According to the elevator optical communication device of the present invention configured as described above, the optical communication distance can be shortest, and the best communication quality can be provided. In addition, since the optical transmitter and receiver are respectively installed on the elevator's aisle wall and the elevator, they are not installed inside the hoistway that is dirty and have a lot of foreign matter and dust, thereby preventing the accumulation of dust in the optical transmitter as much as possible, thereby preventing communication interference caused by foreign substances. You can prevent it. In addition, by installing a controller including a computer on the ceiling of the elevator, it is possible to minimize the length of the wire cable connecting the optical communication receiver and the controller, it is possible to reduce the installation and maintenance costs.
