Description

Wireless communication relay system of elevator {TELECOMMUNICATION REPEATER SYSTEM IN ELEVATOR}

The present invention relates to a wireless communication repeater, and more particularly, to a wireless communication repeater system installed in an elevator.

With the development of communication technology, popularization of various wireless communication devices such as voice, information, and video information such as FM, FAX, mobile phones, and video phones has been progressing rapidly, and thus, wireless communication services regardless of time and place. Increasingly, the efforts to build a nationwide communications network continue, and the installation of satellite communication stations or base stations is increasing.

Nevertheless, there are still communication blind spots which are incapable of service due to weak reception strength in ground or underground structures such as buildings and subways.

Conventionally, in order to solve this problem, it is possible to make a call by installing a repeater in an underground structure such as a subway.

However, in an enclosed area such as an elevator passage in a building, the reception strength of the radio wave is still weak, so that the wireless service cannot be stably received, which still remains as a blind spot of the radio wave.

Therefore, the present inventors have experimented with a commercially available repeater to solve this problem. It has been found that communication is unstable, such as disconnected communication, and high quality service cannot be realized.

Accordingly, an object of the present invention is to enable high-quality wireless service even within a communication blind spot as described above.

Is installed in the elevator passage (1).

What is important here is that at least one central transmission / reception antenna 12e should be provided at appropriate intervals according to the length of the elevator passage 1, that is, the number of floors of the building, so that the breakage of the radio relay does not occur. The reason why a plurality of central transmission / reception antennas 12e should be provided is to increase the strength of communication in one case. Therefore, when the received radio waves are amplified to an excessively high level by the central relay control unit 12c, the amplified radio waves adversely affect the base station. Because you can give.

The terminal repeater 13 is installed at an appropriate position of the upper part of each elevator 3, and the terminal transmitting and receiving antenna 13d connected to one end of the terminal repeater 13 is installed outside the elevator cover, and the terminal repeater 13 The terminal transmission / reception antenna 13e connected to the other end of is provided in the upper part of the elevator 3 together with the elevator terminal repeater 13.

It is important here that the terminal transmit / receive antenna 13d provided on the outside is directed toward the central transmit / receive antenna 12b so as not to be disturbed by radio waves coming in from outside when the lifting door 4 is opened, and shielded from external radio waves. It should be.

Referring to Figure 2 to more specifically understand the configuration and operation of the wireless communication relay system of the elevator according to the present invention configured as described above are as follows.
