Hereinafter, the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce the present invention.

Figure 3 shows a block diagram of the optical distribution box number management apparatus according to an embodiment of the present invention, Figure 4 illustrates a tag (tag) position that should be attached to the optical patch cord connector for the practice of the present invention. 5 is a front view of an optical distribution box according to an embodiment of the present invention, Figure 6 is a panel and optical facing the connector when the connector of the optical patch cord is coupled to the adapter of the optical distribution box according to an embodiment of the present invention The figure which shows the positional relationship of a patch cord connector is shown.

Referring first to FIG. 3, a number of tags are attached to a connector coupled to an end of a lead and lead line for coupling to an adapter arranged transversely and longitudinally in an optical distribution box. An optical patch cord connector is shown in FIG. 4, which is an example of a lead and lead line. As shown in FIG. 4, a tag is attached to one surface of the optical patch cord connector. The tag includes a memory C in which ID information of a tag is recorded and wirelessly stores the tag ID information as described above. LC for generating drive power from a modulator (A) for signal transmission, a controller (B) for controlling the memory (C) and a modulator (A), and a carrier wave transmitted from a serial number management device which is a transceiver And a parallel resonant circuit.

That is, each of the tags 40a to 40n attached to the optical patch cord connector receives the operating power from a carrier wave transmitted from the antennas ANT1 to ANTn, which is one component of the number management device, and is stored in the memory C. It transmits ID information as a wireless signal.

The antennas ANT1 to ANTn transmit and receive radio signals with respective tags 40a to 40n attached to the optical patch cord connector. These antennas ANT1 to ANTn are mounted inside the panel face to face a tag attached to an optical patch cord connector coupled to each adapter as shown in FIG. Referring to the positional relationship of the panel and the position of the adapter to which the optical patch cord connector is coupled, in the optical distribution box according to the embodiment of the present invention, as shown in FIG. Are arranged. Each adapter can also be named the port to which the optical patch cord connector is coupled. On the left side of the plurality of adapters arranged in the longitudinal direction, a panel in which a status indication LED corresponding to each adapter is formed is located. As shown in FIG. 6, a one-to-one antenna corresponding to each adapter is located in the panel surface, for receiving tag ID information from a tag attached to a connector coupled to the adapter. And the status display LED is provided to indicate whether the adapter and the connector is properly coupled to the outside.

That is, the embodiment of the present invention requires the optical patch cord connector to be coupled to the adapter so that the panel surface on which the antenna is located and the tagged connector surface face each other so that the antenna and the tag can normally transmit and receive a radio signal.

Referring to FIG. 3 again, the path selectors 50a to 50n connect one of the antennas to an RF modulator to be described later according to the selection signal S input from the corresponding MCU (Main Control Unit) 54a. . Such path selection units 50a to 50n may be implemented by an analog multiplexer (MUX). In the embodiment of the present invention, it is assumed that each of the path selection units 50a to 50n, the RF demodulation unit, and the MCU to be described later are provided in each panel.

Meanwhile, the RF demodulation units 52a to 52n demodulate and output the radio signal received through the antennas ANT1 to ANTn, and modulate and output the carrier signal having the power strength controlled by the MCU 54a.

The MCUs 54a to 54n located in each panel control the path selector 50a and the RF modulator 52a to transmit and receive a radio signal between the antenna ANT1 and the tag 40a. The demodulation signal outputted from the unit 52a is decoded to collect and store ID information of each tag (40a to 40n). The stored tag ID information is transmitted along with the adapter information to the remote computer through the communication unit 70. For reference, since the adapter information can be known as selection signal information for controlling the path selector 50a, each of the MCUs 54a to 54n inputs tag ID information and its tag according to the control of the path selector 50a. The attached connector can match the combined adapter information and send it to the remote computer.

Meanwhile, in order to transmit the tag ID information and the adapter information to the remote computer in the line management apparatus according to the embodiment of the present invention, a communication unit 70 for network connection should be provided. RS-232C can be used as the communication unit 70. The communication unit 70 transmits the collected tag ID information together with the adapter information to the remote computer. Since the communication cable is provided in proportion to the number of MCUs, the communication unit 70 collects each of the MCUs 54a to 54n. It is preferable to further include a link MCU (60) for collecting the collected tag ID information together with the adapter information to transmit to the remote computer through the communication unit (70). In this case, the MCUs 54a to 54n pass the tag ID information collected at the request of the link MCU 60 to the link MCU 60 together with the adapter information.

Meanwhile, the line management apparatus according to the embodiment of the present invention may further include LED display units 80a to 80n. The LED display unit is provided for displaying an abnormally coupled state of the tagged connector and the adapter. Each LED constituting the LED display unit is mounted at a panel position corresponding one-to-one with the adapter to be lit by the MCU 54a to 54n. Flashing is controlled. Control of lighting and blinking of the LED will be described in detail with reference to FIG. 7.

7 is a flowchart illustrating an RF transmission power initial setting according to an embodiment of the present invention. This initial RF transmission power setup process is necessary to minimize signal interference with tags attached to connectors coupled to adjacent adapters, and is preferably performed for one-to-one antennas corresponding to each adapter. The initial RF transmission power setting process may be performed by each of the MCUs 54a to 54n under the control of a remote computer (server), and each MCU 54a to 54n by an operator command during the initial optical distribution box line operation. May be carried out in the field.

The RF transmission power initial setting process will now be described.

First, assuming that the optical patch cord connector attached with tag 1 (40a) is connected to the adapter on the right side of the panel on which the antenna ANT1 is attached, the initial setting command for RF transmission power is received from the remote computer (server). MCU1 54a controls the oscillation voltage of RF modulator 1 52a to maximize RF transmit power. The intensity of the transmit power can be adjusted according to the control of the oscillation voltage. The MCU1 54a firstly outputs the RF transmit power at the maximum in 100 steps. In this case, it is obvious that each of the plurality of antennas ANT1 to ANTn provided in one panel can be selected according to the selection signal S.

In this way, if a carrier having the maximum output power is transmitted through any one antenna ANT1, power is removed from the carrier in tag 1 40a, and the controller modulates the tag ID stored in the memory into an RF signal and outputs the RF signal. .

The RF signal is received through the antenna mounted on the panel (step 110), and then input to the RF demodulator 1 (52a) through the path selector 1 (50a) and demodulated into digital data and input to the MCU1 (54a). MCU1 54a then checks whether an error has occurred in the demodulated digital data, that is, the received data (step 120). As the inspection method, it is possible to inspect whether or not normal tag ID information is decoded by decoding the input digital data. In addition, parity bit information may be used to inspect whether there is an error in the received data.

If no error occurs in the received data in step 120, that is, if the tag ID information is normally received, the MCU1 54a proceeds to step 130 and sets the RF transmission power one step down, and then sets the RF transmission power to be transmitted. The modulation / demodulation unit 1 (52a) is controlled (step 140). Accordingly, the radio signal of the tag ID information is transmitted again from the tag 1 40a, and the MCU1 54a can check whether there is an error in the tag ID information through steps 110 and 120 described above. If the error of the tag ID information does not occur in step 120, the MCU1 54a again lowers the RF transmission power by one step and transmits an RF signal having the lowered power strength.

If an error occurs in the tag ID information received as a result of the inspection in step 120, the MCU1 54a proceeds to step 150 to set the RF transmission power immediately before the error to the rated output value.

That is, in the initial setting mode of the RF transmission power according to the embodiment of the present invention, while checking the error occurrence of the tag ID information while sequentially descending the intensity of the RF transmission power step by step from the maximum value, that is, the value set immediately before the error occurrence, that is, tag and By setting the minimum transmit power required for the transmission and reception of radio signals to the rated output value, signal interference with tags attached to connectors coupled to adjacent adapters is minimized.

As described above, in the initial setting mode of the RF transmission power, after setting the tag attached to the connector and the minimum transmission power strength for transmitting / receiving a radio signal for each antenna, the tag is set to the strength of the transmission power set in the normal operation mode. Read ID information.

Referring to the operation of the line management device in the normal operation mode,

Each of the MCUs 54a to 54n located in each panel controls the corresponding path selectors 50a and 50n and the RF modulators 52a and 52n so that carriers are transmitted at the transmit power strength values set in the initial setting mode. do. That is, if the RF modulation and demodulation units 52a and 52n are controlled so that one antenna is selected by controlling the path selectors 50a and 50n and then the carrier having the minimum transmission power is transmitted. 50a, 50n) and carrier transmission through the antenna. By the carrier transmission, a radio signal corresponding to the tag ID information is transmitted from the tag, and the radio signal is input to the RF modulators 52a and 52n through the selected antenna and the path selectors 50a and 50n. The RF modulation and demodulation sections 52a and 52n output digital data corresponding to the tag ID information.

As the digital data is decoded into the tag ID information in each of the MCUs 54a and 54n, each of the MCUs 54a and 54n can collect the ID information of the tag attached to the connector coupled to the respective adapter. Since the ID information of such a tag indicates the inlet and the outgoing lines of the optical patch cord connector which is eventually coupled to the adapter, the remote computer (server) has each MCU 54a, 54n and the link MCU 60 and the communication unit 70. ) Through the incoming and outgoing track information (corresponding to the tag ID information) and adapter information can be received.

In addition, the remote computer (server) can visualize the incoming and outgoing line information coupled to the adapter based on each display control program together with the connector normal coupling state, and an example of the simple display form is shown in Table 1 below. Shown.

Adapter Information Incoming Line (Tag ID Information) Outgoing Line (Tag ID Information)  Combination Adapter 1 101 202 normal Adapter 2 102 205 abnormal Adapter n 110 120 normal

As shown in Table 1, in order to indicate whether the adapter and the connector are normally connected to the remote computer (server), each of the MCUs 54a and 54n transmits a radio signal having the rated output value set in the initial setting mode, and in response thereto. If an error occurs in the received signal, it can be implemented by transmitting the corresponding adapter information to a remote computer (server).

As described above, since the optical distribution box number management apparatus according to the embodiment of the present invention can read the tag ID attached to the optical patch cord connector coupled to each adapter, the read tag ID information and the adapter information can be read. By matching and transmitting to a computer (server) located at a remote location, the remote site can monitor the information of the incoming line and the outgoing line coupled to the optical distribution box together with the adapter information.

In addition, in the embodiment of the present invention, if a connector to be coupled to each adapter of the optical distribution box is abnormally coupled, the transmission of the tag ID information from the tag cannot be performed as the transmission of the carrier is performed with the minimum transmission power strength. . This is a case out of the transmission distance of the radio signal. In this case, since there is no data to be decoded by the MCU, it is determined that the received data is an error. When the received data error is determined, by turning on or blinking the LED with the MCU, the operator can check the non-coupling state of the connector in the field (or remote location).

As described above, the present invention has an advantage of visualizing the coupling relationship between the adapter and the line because the information of the inlet line and the outgoing line coupled to the adapters of the optical distribution box can be known through a tag. According to the information, there is an advantage in that the number management of the optical distribution box becomes easy.

In addition, the present invention has the convenience that can be checked in the field as well as the remote coupling state of the connector coupled to each adapter of the optical distribution box, furthermore, the present invention has the advantage that can be computerized the number management of the optical distribution box. .
