Description

Technical Field [0001] The present invention relates to a wireless communication device for an elevator,

The present invention relates to a wireless communication device for an elevator, and more particularly to a wireless communication device for an elevator that does not require conventional wired communication or optical communication.

2. Description of the Related Art As an example of installing a monitor for displaying information in an elevator, specifically, a door, a wall surface, or a ceiling is increasing, wired communication or optical communication is increasingly adopted to transmit data from the outside to a monitor.

1 is a cross-sectional view of an elevator hoistway showing an optical communication system. For optical communication, an optical communication transmitter 140 is 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, data transmission is generally performed between the transmitter 140 and the receiver 150 through the optical communication in a state where the elevator E has reached the lowest point as shown in the drawing. Such data is transmitted to the monitor M To be displayed.

In this case, as shown in the drawing, there is a problem that the optical communication distance between the transmitter and the receiver is about one height of a building or an average height of a man in general, so that the quality of optical communication is lowered. The shorter the communication distance, the better the quality of optical communication. In addition, since the transmitter is installed on the bottom surface of the hoistway, the transmitter is exposed to a relatively dirty environment, and dust or foreign matter accumulates on the surface of the transmitter. Particularly, since the elevator hoistway is very frequently lifted and moved by an elevator, foreign matter such as dust is very large, so that the surface of the transmitter is covered with foreign matter. In this case, the optical communication is disturbed, and data transmission will not be performed properly.

Further, as shown in the drawing, since the controller C including the computer installed in the machine room located at the upper end of the elevator hoistway and the optical communication transmitter 140 must be connected by a wire cable, the length of the wire cable is very long, There arises a problem in terms of maintenance and cost of the cable.

On the other hand, when wired communication is used, there is a problem that the wired cable becomes longer.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to eliminate the optical communication itself, which has been a problem in the related art, and to enable wireless communication.

The present invention also aims to minimize installation and maintenance costs by minimizing the length of conventional long cable connections.

In order to accomplish the object of the present invention, the present invention provides a data transmitting system comprising: a data transmitter (10) installed on a wall surface of a hall near a hall door in a state in which a hall door (D1) of an elevator is closed; A data receiver 20 which is installed inside the safety tissue S of the elevator door or at the front edge D4 of the cage door D2 and receives digital data by wireless communication from the data transmitter 10; A controller (C) connected to the data receiver (20) by wire, installed on the ceiling of the elevator (E), receiving data from the data receiver (20) and converting the data into image data; And a monitor (M) connected to the controller (C) by wires and installed on a door, a wall surface or a ceiling of the elevator (E) and receiving and displaying image data from the controller.

In the present invention, the data transmitter 10 can transmit data using LTE, WiFi or wireless LAN.

It is also preferable that the data receiver 10 is arranged to be long along the whole or a part of the length of the leading edge of the safe tissue S or the cage door D2.

According to the present invention configured as described above, since the optical communication itself is unnecessary, the related problems can be solved and the installation cost can be greatly reduced.

In addition, according to the present invention, it is possible to minimize installation and maintenance cost by minimizing the length of a conventional long cable for connection.

In order to eliminate the conventional optical communication, the interval between the wireless data transceivers must be minimized. To this end, the data transmitter 10 is installed on the wall surface of the hall (hall) near the hall door with the hall door D1 of the elevator closed as shown in Fig. As will be described later, in this case, the wireless communication distance is minimized. As shown in Fig. 2A, an antenna-combined data receiver 20 for receiving digital data by wireless communication from the data transmitter 10 is installed inside the safety tissue S of the elevator door.

3 is a plan view showing a configuration of the wireless communication apparatus of the present invention when the elevator door is opened, and FIG. 3A is an enlarged view of a portion A in FIG.

When the elevator door is opened, the safety tissue S protrudes forward as shown in the drawing for safety of passengers. When the safety tissue S protrudes, the receiver 20 inside the safety tissue is exposed to the data transmitter 10, and even during the time when the elevator door is opened and then completely closed again, It is possible to receive sufficient data wirelessly.

4 is a rear view showing a state in which the cage door D2 is opened to show the protruding structure of the safety tissue S. [

As shown in the figure, when the cage door D2 is opened, the link L is rotated in the direction of the arrow by the gravity so that the safety tissue S protrudes forward from the position indicated by the broken line to the position indicated by the solid line. In such a protruded state, the receiver 20 disposed along the length in the safety tissue S may be exposed to the data transmitter 10 to allow wireless communication. Although the receiver 20 is formed over the entire length of one of the safety tissues S, if necessary, the receiver can be installed in the other safety shoe or both safety tissues, and the length of the receiver 20 can be appropriately adjusted . However, it is advantageous to receive the data 20 as long as possible.

5 is an exploded perspective view showing the connection relationship of the entire configuration of the present invention.

A controller (C) including a computer is connected to the data receiver (20) by wire. Such a controller is preferably installed on the ceiling of the elevator (E). The controller C receives data from the data receiver 20 and converts the data into image data.

The monitor (M) is connected to the controller (C) by wire. Although the figure shows that the monitor M is installed on the cage door D2 of the elevator E, the monitor can be installed on the wall or ceiling inside the elevator if necessary. The monitor M not only receives and displays image data from the controller but also can display various kinds of information necessary for building management.

On the other hand, the safety of passengers can be achieved by using optical sensors or other sensors without safety shoes. In this case, since there is no safety shoe, the data receiver 20 is installed at the front edge of the front edge of the cage door D2. Fig. 6 is a view corresponding to Fig. 5 showing a state in which the data receiver 20 is installed at the front edge of the cage door D2.

Alternatively, the data receiver 20 may be installed on the front edge of the cage door frame D3, which is a door frame supporting the cage door D2. 7 is a detailed view showing a state in which the data receiver 20 is installed on the front edge of the cage door frame D3. In the above two cases, data communication will be performed when the elevator door is completely opened.

In this case, all other configurations are the same as those in the above-described embodiment.

Although the construction of the present invention has been described above, it is most preferable that the present invention is embodied in a layer where the elevator is most stopped, for example, a first floor. However, if desired, the present invention may be implemented in other layers, and in some cases, the present invention may be implemented in various layers.
