Repeater output automatic correction apparatus according to an embodiment of the present invention is included in the plurality of repeaters 200, as shown in Figure 1, the repeater management server 100 is a plurality of repeaters 200 To manage.

Repeater output automatic correction device according to an embodiment of the present invention using the gain information and automatic level control compensation information (ALC: Auto Level control) manually set by the operator as the information to adjust the output of the input signal Compensate for the output of the signal.

Repeater output automatic correction apparatus according to an embodiment of the present invention includes a level control module with an automatic level control function, the output of the input signal using the automatic level control compensation information is a certain range (preferably service Automatically compensates for the output so that it is within the range possible).

In one embodiment of the present invention, the automatic level control compensation information may be automatic level control attenuation information (ALC Atten), and the gain information may be user attenuation information (User Atten).

Repeater output automatic correction apparatus according to an embodiment of the present invention may include an amplifier for amplifying the input signal, the amplifier may be configured in a multi-stage amplification, such amplification unit may be provided with an attenuator have.

The attenuator of the repeater output automatic correction device according to an embodiment of the present invention is used for level adjustment, measurement, matching, etc. in a high frequency circuit, and may perform a function of attenuating a signal to a predetermined power level.

According to an embodiment of the present invention, in a circuit in which various high frequency components are combined, it may be necessary to insert an attenuator to adjust the power level. For example, in the case of a multistage amplifier, a gain between input and output may be set to a predetermined value. To do this, we need to adjust the gain by putting an attenuator somewhere.

Hereinafter, a repeater output automatic correction apparatus according to an embodiment of the present invention will be described in detail with reference to FIG. 2.

2 is a block diagram showing the configuration of a repeater output automatic correction apparatus according to an embodiment of the present invention.

The repeater output automatic correction apparatus according to an embodiment of the present invention monitors the forward (Tx: Transmitter) output information and the reverse (Rx: Receiver) output information of the repeater by using the output information monitor 210.

In this case, according to an embodiment of the present invention, the signal size unit of the two output information may be measured in dB.

The output information compensator 220 according to an embodiment of the present invention includes a level control module to drive an automatic level control function. That is, according to an embodiment of the present invention, when the output information is less than or equal to the reference value, the forward (Tx) transmitter information or the reverse (Rx: receiver) output information is used by using auto level control (ALC) compensation information. Control to automatically compensate for each or simultaneously output.

For example, the repeater output automatic correction device according to an embodiment of the present invention, if it is necessary to simultaneously consider the forward and reverse outputs, such as RF repeater, forward (Tx: Transmitter) output information and reverse (Rx: Receiver) output information Compensation can be done at the same time.

As another example, the repeater output automatic correction apparatus according to an embodiment of the present invention uses only automatic level control (ALC) information when the output information is less than a reference value when considering only forward output, such as an optical repeater. One of the forward (Tx: Transmitter) output information or the reverse (Rx: Receiver) output information may be compensated.

In addition, the output information compensation unit 220 according to an embodiment of the present invention operates to compensate for the forward output information and the reverse output information using the automatic level control compensation information, the forward output information and the reverse output The information is kept above the reference value.

Therefore, according to an embodiment of the present invention, when the forward output information and the reverse output information are equal to or less than a reference value while the output information compensator 220 is operated, the automatic level control compensation information is exhausted. In this case, the forward output information and the reverse output information may be automatically compensated.

According to an embodiment of the present invention, the case where the automatic level control compensation information is exhausted means that the forward output information and the reverse output information by the output information compensation unit 220 as much as the automatic level control compensation information. As a state in which all of them are compensated, the state in which the output is compensated to the maximum, that is, the value of the automatic level control compensation information expressed by the automatic level control attenuation information ALC Atten becomes '0 dB'. At this time, according to an embodiment of the present invention, the level control module is no longer able to maintain the output above the reference value by the automatic level control function.

The gain information switching unit 230 according to an embodiment of the present invention automatically adjusts the value of the automatic level control compensation information so as to correspond to a value of decreasing the predetermined gain information in a predetermined unit within the predetermined gain information range. To increase.

For example, according to an embodiment of the present invention, if the preset gain information is 14 dB and the predetermined unit is 6 dB, reducing the gain information by 6 dB automatically switches to the automatic level control compensation information by a reduced value. In conclusion, the automatic level control compensation information may be increased by 6 dB.

For example, the preset gain information according to an embodiment of the present invention is reduced by a predetermined unit (ex 8 dB), and the automatic level control compensation represented by the automatic level control attenuation information (ALC Atten) immediately after switching. The information value is changed from '0 dB' to a predetermined unit (ex 6 dB) so that automatic output control can be additionally performed by the predetermined unit.

That is, according to the exemplary embodiment of the present invention, the output information of the repeater 200 may be automatically compensated as the output information of the repeater 200 decreases according to the margin of the gain information.

According to an embodiment of the present invention, if the gain information does not have enough spare information so as not to be converted into the automatic level control compensation information, the output information cannot be compensated. Select and notify the repeater so that it can be checked.

That is, the inspection target local determination unit 240 according to an embodiment of the present invention may determine that the sum of the automatic level control compensation information and the gain information is less than the predetermined degradation target information so as to be determined as a degraded repeater among the repeaters. For example, in the case of 7 dB), the repeater is selected as the target to be checked, and the notification unit 250 transmits information indicating that the repeater is the check target repeater to the repeater management server 100 so that an operator can know. do.

As described above, embodiments of the present invention will be described in more detail with reference to FIGS. 3 to 4.

In the automatic repeater output compensation device according to an embodiment of the present invention, when the output of the repeater 200 is continuously reduced, such as oscillator (Amp) and output driver (Tx-drv) degradation, the repeater (through the process shown in FIG. The output of 200 may be determined to be compensated and inspected.

3 is a first embodiment illustrating a repeater output automatic compensation process according to an embodiment of the present invention.

For example, as shown in FIG. 3, when the gain information set by the first operator is set to 14 dB and the automatic level control compensation information is set to 6 dB according to an embodiment of the present invention, the gain information is 14 dB and the automatic level. The control compensation information is maintained at 6 dB (i.e. 20 dB of attenuation) and the output is maintained at 40 dB so that the output is well maintained above the reference value (38 dB).

Subsequently, when the output information decreases by 8 dB due to deterioration of the repeater 200 according to an embodiment of the present invention, the output information compensator 220 adjusts the automatic level control compensation information to compensate for the output. For example, according to an embodiment of the present invention, the automatic level control compensation information may be 0 db (ie, 14 dB of attenuation) to compensate for the output information by 6 dB to maintain 38 dB above the reference value.

In this case, since the gain information switching unit 230 according to the exemplary embodiment of the present invention compensates all the output information as much as the automatic level control compensation information, the gain information is switched by a predetermined unit (6 dB) so that the automatic level is changed. The control compensation information is incremented and reset (310).

Then, according to an embodiment of the present invention, the gain information is reset to 8 dB, and the automatic level control compensation information is reset to 6 dB (ie, 14 dB of attenuation).

Next, when the output information decreases by 6 dB again due to the continuous deterioration of the repeater 200, the output information compensator 220 uses the reset automatic level control compensation information to output the output. The information is compensated again, and the gain information switching unit 230 may increase the automatic level control compensation information by switching the gain information again (320).

According to an embodiment of the present invention, if the gain information for compensating the output information is no longer available by repeating the above steps 310 to 320 (that is, the sum of the gain information and the automatic level control compensation information is a predetermined value). (7 dB) or when the automatic level control compensation information is '0 dB' and the output information is below the reference value) The inspection target local determination unit 240 moves the repeater 200 from which the above result is obtained to the inspection target local area. Can select

In addition, according to an embodiment of the present invention, the notification unit 250, when the repeater 200 is selected as the local to be checked, the operator to send information indicating that the repeater is the check target repeater to the repeater management server so that the operator can know do.

According to an embodiment of the present invention, even when the gain information is less than or equal to a predetermined unit which is a conversion unit, the remaining gain information may be converted into automatic level control compensation information to maintain the output of the repeater (330).

In addition, according to an embodiment of the present invention, when the automatic output compensation is no longer possible (both the gain information and the automatic level control compensation information are 0 dB), the alarm unit 250 informs the relay management server of the information indicating that the automatic output compensation is impossible. It transmits so that the operator can know (340).

In addition, the output automatic compensation device according to an embodiment of the present invention compensates the output of the repeater 200 through the process as shown in FIG. And whether or not to be inspected can be determined.

Figure 4 is a second embodiment showing a repeater output automatic compensation process according to an embodiment of the present invention.

According to an embodiment of the present invention, if the gain information set by the first operator is 14 dB, the automatic level control compensation information is 6 dB, and the output information is 40 dBm, the output information compensation unit 220 is reduced by 8 dB. ) Maintains the output information at 38 dB using automatic level control compensation information.

In this case, since the gain information switching unit 230 according to the exemplary embodiment of the present invention compensates all the output information as much as the automatic level control compensation information, the gain information switching unit switches the gain information by a predetermined unit (6 dB) to compensate for the automatic level control compensation. The information is incremented and reset (410).

Next, when the output information of the repeater 200 decreases by 6 dB according to one embodiment of the present invention, the output information compensator 220 uses the reset set automatic level control compensation information to change the output information. In operation 420, the gain information switching unit 230 switches the gain information to increase and reset the automatic level control compensation information.

At this time, the gain information is 2dB and the automatic level control compensation information is reset to 6dB to perform the automatic level control compensation function, and the output of the repeater 200 is restored to normal according to an embodiment of the present invention. When the information rises by 6 dB, the repeater automatic output compensation device adjusts the automatic level control compensation information to adjust the automatic level control compensation information to 8 dB to compensate for the output information to 42 dB, It can be kept above the reference value.

At this time, if the output is further increased by 8 dB according to an embodiment of the present invention, the automatic level control compensation information may be maintained at or above the reference value by compensating the output at 42 dB with 16 dB. In this case, all of the gain information is maintained at 2 dB (430).

In addition, the repeater automatic output compensation device according to an embodiment of the present invention determines the case where the input information is not received by the repeater 200 due to the moment of the upper local failure, in this case to determine the temporary phenomenon to the repeater management server The notification may be performed, and control of the gain information conversion of the present invention may not be performed.

That is, the determination unit 260 according to an embodiment of the present invention determines that the output information monitored by the output information monitoring unit 210 is absent or is lower than the second reference value, and is determined as a temporary phenomenon, and the output information compensation unit 220 is determined. In addition, the control unit 110 may stop the operation of the gain information switching unit 230, and may transmit the low input alarm information to the repeater management server 100.

5 is a diagram illustrating an example of transmitting repeater low input alarm information according to the present invention.

For example, suppose that the gain information set by the first operator is 14 dB, the automatic level control compensation information is 6 dB, and the output information is 40 dBm according to an embodiment of the present invention.

At this time, the repeater output automatic correction device according to an embodiment of the present invention, as shown in Figure 5, while monitoring the output state 510, the input information is not received from the upper local of the repeater 200 When the output information does not come out at all or is lower than the second reference value, it is determined as a temporary phenomenon, the output information compensator 220 and the gain information control unit 230 are controlled to stop the operation, and the low input to the repeater management server 100. Alarm information may be sent (520).
