BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intelligent light distribution device, and more particularly, to an intelligent distribution device that can easily distinguish an optical communication line, visually confirm the presence or absence of an optical signal, and know the magnitude of an optical signal level.

In recent years, communication using mobile phones and the Internet has rapidly progressed toward transmitting still and moving pictures beyond the level of exchanging voice and text data. The demand for technology is growing exponentially day by day. As a result, communication demand is rapidly expanding in all areas of society, and in order to satisfy this problem, the transmission speed of communication networks and the spread of optical cable communication networks are rapidly progressing.

Accordingly, in order to provide various wired / wireless communication services over a wide area, optical cable lines extending to various areas are constituted, and connection points of optical communication lines in optical distribution devices in communication stations for connecting these optical cable lines become more and more. . Therefore, connection management of complicated optical communication lines is absolutely necessary in the optical distribution device.

However, conventionally, the optical distribution device merely serves as a connector box of the optical communication line, and each optical communication line is distinguished by attaching a label indicating a number or the like corresponding to each optical communication line having a connection point in the optical distribution device. It was managed to a degree. Therefore, in order to check whether there is an optical signal in each optical communication line, the operator has to check the existence of the optical signal by contrasting each optical communication line through a label, and thus a great difficulty when a large number of optical communication lines are concentrated. There is this.

In addition, conventionally, since the optical signal level of each optical communication line input to the optical distribution device is not known, there is a problem that the operator must perform various measurement tests when a failure occurs.

In addition, although the unmanned transmission station is gradually increasing, there is a problem that the conventional optical distribution device does not have a function that can be managed remotely.

Accordingly, it is an object of the present invention to provide an optical distribution device capable of confirming in real time the presence or absence of an optical signal on each optical communication line.

Another object of the present invention is to provide an optical distribution device which displays the optical signal level of the current optical communication line in real time.

It is still another object of the present invention to provide an optical distribution device capable of obtaining optical communication line related information through a remote connection.

Features and advantages of the present invention for achieving the above objects will be clearly understood through the following examples.

An object of the present invention is to provide a connection point for a plurality of optical communication lines, comprising: a plurality of optical conversion elements for receiving a portion of an optical signal corresponding to each optical communication line and converting the optical signal into an electrical signal; A light emitting element provided corresponding to each optical communication line and indicating whether or not an optical signal exists in each optical communication line; A driving module for controlling on / off of the light emitting device; And a control unit configured to receive an electrical signal from each optical conversion element, determine whether an optical signal is present in each optical communication line based on the electrical signal, and transmit the determination result to the driving module. Is achieved by an intelligent light distribution device that controls on / off of the light emitting element based on the determination result of the control unit.

According to such a structure, the presence or absence of the optical signal of each optical communication line can be confirmed in real time in the optical distribution apparatus.

Preferably, the apparatus further comprises a display unit for displaying an optical signal level of each communication line and an identifier corresponding thereto, wherein the controller is configured to display an optical signal level of each optical communication line based on an electrical signal received from each optical conversion element. The measured optical signal level may be displayed on the display unit together with an identifier corresponding to each optical communication line.

According to this structure, the optical signal level of the current optical communication line can be confirmed in real time in the optical distribution device.

Preferably, the control unit may selectively provide the presence or absence of the optical signal or the measured optical signal level according to a request of a terminal device remotely connected through TCP / IP.

According to this configuration, the optical communication line related information can be obtained from the optical distribution device by remote connection via a network such as the Internet.

Preferably, the light conversion element, the driving module and the light emitting element may be mounted on a single printed circuit board.

Next, a light distribution apparatus according to an embodiment of the present invention will be described with reference to the drawings.

1 is a block diagram showing a light distribution device of the present invention.

In the optical connector 110 of the optical distribution apparatus 100, a plurality of input optical communication lines (optical cables) and a plurality of output optical communication lines are connected. Optical splitters 111, 112, and 113 are connected to each of the optical communication lines # 1 to # 48 to separate and output a part of the optical signal. For example, an optical signal of 1% may be output from the entire optical signal.

The photoelectric conversion elements 131, 132, and 133, such as photodiodes, are connected to the respective optical splitters 111, 112, and 113 to receive an optical signal, convert the optical signal into an electrical signal, and transmit the converted optical signal to the controller 150.

The LED driving module 122 turns on / off the light emitting devices 141, 142, and 143 such as LEDs under the control of the controller 150. The output patterns of the light conversion elements 131, 132, and 133 and the LED driving module 122 may be mounted on the printed circuit board 120 at one time, and the LEDs 141, 142, and 143 may correspond to the respective optical communication lines. It has an identifier such as a number or a number to identify it.

The controller 150 may be implemented by, for example, a microprocessor, and has a large on / off control of the LEDs 141, 142, and 143, information display on the LCD 160, and a communication function.

LED Come on off  Control

As described above, when the optical conversion elements 131, 132, and 133 receive a part of the optical signal corresponding to each optical communication line # 1 to # 48, convert the optical signal into an electrical signal, and transmit the electrical signal to the control unit 150. The controller 150 determines whether an optical signal exists in the corresponding optical communication line based on the received electrical signal.

Subsequently, the LED driving module 122 is controlled according to the determination result to control the on / off of the LEDs 141, 142, and 143. Specifically, if the electric signal is not detected from the specific optical communication line as a result of the determination, it is determined that there is no optical signal on the optical communication line, and the LEDs 141, 142, and 143 correspondingly identified are turned off. In the opposite case, the correspondingly identified LEDs 141, 142, 143 are turned on.

LCD  Information display

Similarly, the controller 150 determines the presence or absence of an optical signal of the corresponding optical communication line and measures the optical signal level based on the electrical signals received from the optical conversion elements 131, 132, and 133.

Subsequently, the determined presence or absence of the optical signal and the measured optical signal level are displayed on the LCD 160. 2 is a screen illustrating an example of information displayed on an LCD. Referring to FIG. 2, information is divided into an optical communication line accommodation port number, line number information for identifying an optical communication line, an optical signal, and an optical signal level item. Specifically, port numbers # 1 to # 48 for accommodating an optical communication line are listed in the port number, and a generic name of the optical communication line (for example, A-company B-company # 1) is listed in the line number information item. The item indicates the presence or absence of ○ or ×, and the optical signal level indicates the optical signal level in decibels (dB).

In this embodiment, both the optical signal item and the optical signal level item are displayed, but they may be selectively displayed.

Communication function

When a request is made from a computer system 300 remotely connected through a TCP / IP network such as the Internet, the controller 150 provides an optical signal level or line length information of an output optical port of an optical communication line.

3 is a configuration diagram of an optical communication transmission path.

As shown, the operator may receive light from the optical distribution apparatuses 100, 101, and 102 of each transmitting station A, B, and C with a remote web connection through the TCP / IP 200 from the computer terminal 300. Output signal of the communication line The optical signal level of the optical port and line length information which is the connection information of the optical communication line can be obtained.

According to this configuration, since the information such as the connection status of the optical communication line and the signal level of the output optical port can be obtained by remotely connecting the optical distribution device, stable optical communication line operation is possible.

In the above description, the embodiment of the present invention has been described, but various changes and modifications can be made by those skilled in the art. Therefore, the scope of the present invention should not be limited to the above embodiment, but should be interpreted by the claims described below.
