Through the measurement information of the optical fiber, information such as failure point or loss characteristic of the optical fiber is measured. The optical switch 300 is a device for selecting an optical fiber network to be monitored. The optical switch 300 and the optical path measuring device 200 is matched 1: 1. The WDM filter 400 filters the service signal of the optical fiber network and the monitoring signal of the optical fiber measuring apparatus 200. The optical path measuring apparatus 200, the optical switch 300, and the WDM filter 400 are configurations of a known optical path monitoring system, and a detailed description thereof will be omitted.

In addition, as shown in Figure 1, in the case of the backbone network that connects the network, the optical path is connected through a manhole 800 at a certain distance, in the case of the subscriber network in the ODC 500, Distribution cable, which is the feeder cable end It consists of an ODP 600 which is a drop cable enclosure for connecting the ONT 700. On the other hand, the optical fiber network is a matter that changes depending on the design method of the telecommunication company, the geographical environment, etc. and is not limited to the configuration of FIG.

Referring to FIG. 2, the integrated monitoring apparatus 100 includes a matching unit 110, a data converter 120, a data storage unit 130, a reference event unit 140, an operation event unit 150, and a control manager 160. ) May be included.

The matching unit 110 controls the optical path measuring apparatus 200 for measuring the sample information of the optical path, and is a device for receiving the sample information from the optical path measuring apparatus 200.

As shown in FIG. 2, the matching unit 110 includes a light ray mapping unit 111, a profile storage unit 112, a profile identification unit 113, a measurement control unit 114, a signal selection unit 115, and a profile setting unit 116. ) May be included.

The optical ray mapping unit 111 is a device for mapping the optical switch 300 and the optical path interlocked with the optical path measuring device 200. On the other hand, the optical path and the port of the optical switch 300 is connected in a 1: 1 relationship.

The profile storage unit 112 is a device for storing profile information including control parameters and threshold values according to the monitoring environment of the optical fiber network. In the optical fiber network, control parameters and thresholds are set according to the type of optical optical fiber network such as backbone network, PON network, measuring distance, and monitoring network profile. Therefore, the profile storage unit 112 specifies and stores a control parameter and a threshold value according to the monitoring environment in advance.

The profile identification unit 113 identifies specific profile information corresponding to the optical path. For example, when the optical path is a PON network, the profile identification unit 113 identifies specific profile information corresponding to the PON network.

The signal selector 115 is a device that selects at least one signal of a reference wave or a measurement wave used in measuring light. On the other hand, when the optical path is automatically monitored by the integrated management device 100, or triggering through failure interworking with OSS (Operation Support System) / NMS (Network Management System) / EMS (Element Management System), the measurement wave is automatically measured. Is selected.

The measurement control unit 114 is a device for controlling the optical path measuring apparatus 200 to measure the optical path according to the identified specific profile information and the selected specific signal.

On the other hand, when the specific profile information is identified, the profile setting unit 116 sets another specific profile information including another control parameter and another threshold value according to the characteristics of the optical path.

On the other hand, in order to connect the matching unit 100 and the optical fiber measuring apparatus 200 uses a variety of protocols, such as TCP / IP, XML, USB, manufacturer's own standards. As in the case of FIG. 2, when the optical path measuring apparatus 200 includes a plurality, the matching unit 100 is also configured to correspond to the number of the optical path measuring apparatus 200. Here, the plurality of optical fiber measuring apparatuses 200 may be configured with different types of measuring apparatuses, and different protocol standards may be used.

For example, when the optical fiber measuring apparatus 200A uses TCP / IP protocol, the optical fiber optical measuring apparatus 200B is XML, and the optical fiber optical measuring apparatus 200C uses USB protocol, the matching unit 100 may use various connection interfaces and protocol standards. Modularized to fit Therefore, the matching unit 100 is not limited to the connection interface and the protocol of the optical fiber measuring apparatus 200, and it is possible to transmit and receive information with the heterogeneous optical fiber optical measuring apparatus 200.

Therefore, the matching unit 100 may control the plurality of heterogeneous optical ray measurement apparatus 200 and receive sample information from the heterogeneous optical ray measurement apparatus 200. The sample information received by the matching unit 100 is data measured by a heterogeneous optical fiber measuring apparatus, and has different data formats.

The data converter 120 converts the sample information transmitted from the at least one optical path measuring apparatus 200 into preset standard data. As described above, as the sample information received by the matching unit 110 is formed in different data formats, the sample information is converted into preset standard data for shaping the data. For example, when preset standard data is set to SR4731 of Telcordia (Telcordia Technologies Inc.), the standard information transmitted from the heterogeneous optical fiber measuring apparatus 200 is converted into a data format that satisfies SR4731. SR4731 is a data format provided by Telcordia of OTDR.

The converted standard data is stored in the data storage unit 130. The data storage unit 130 stores a trace view of the measurement results and data history management in a database form for standard data analysis.

The reference event unit 140 is a device that generates a reference event by analyzing standard data to determine a reference wave used when measuring sample information. Referring to FIG. 2, the reference event 140 includes a reference data analysis unit 141, a mood wave determination unit 142, a reference event generation unit 143, a reference threshold analysis unit 144, and a reference threshold analysis unit 145. ), The reference event storage unit 146 may be included.

The reference data analyzer 141 is a device that analyzes standard data analysis information from the standard data when the stored standard data is set as the reference wave by the matching unit 110. Standard data analysis information includes insertion loss, specific peak point, connection point and noise point information of the termination to the optical path.

The reference wave determination unit 142 determines whether the analyzed standard data analysis information satisfies a predetermined reference condition referenced to determine the reference wave.

If the standard data analysis information satisfies the reference condition, the reference event generation unit 143 generates a reference event based on the standard data. The reference event includes event information on the optical core connection point of the optical line, the peak point occurring at the optical line resource point, and the optical termination.

When the standard data analysis information does not satisfy the reference event condition, the reference threshold analysis unit 144 analyzes an application condition of a specific threshold value corresponding to the optical fiber network set by the matching unit 110. In this case, as a management item for determining an application condition, values such as a connection loss threshold value, a reflection threshold value, an optical termination threshold value, a noise peak level threshold value, and the like may be included.

The reference threshold value determination unit 145 is a device that performs a condition for generating a reference event again when there is a value for the measurement interval that satisfies the application condition for the threshold value. On the other hand, if the application condition is not satisfied, the reference event is not generated.

As shown in FIG. 2, the operation event unit 150 includes a reference event mapping unit 151, an operation event detection unit 152, an operation data analysis unit 153, a failure condition setting unit 154, and an operation event identification unit 155. The error information collecting unit 156 may include an active threshold calculating unit 157 and a threshold applying unit 158.

The reference event mapping unit 151 is an apparatus for identifying at least one specific reference event mapped with resource information of a light path in the stored reference event list. Here, the resource information of the optical path includes resource information such as a manhole, a handhole, a power pole, an enclosure, a multi-service access node (MSAN), and an ONT. Accordingly, the reference event mapping unit 151 identifies the reference event corresponding to the resource information of a specific light ray in the reference event list by mapping the resource information of the light path in the reference event list. For example, when the A reference event including the specific Peek point information is information corresponding to the optical end of the individual user, the reference event mapping unit 151 maps the A reference event to resource information of the optical end of the individual user. To be identified.

The operation event detector 152 is a device that detects a specific reference event as an operation event of resource information with a mapped ray. The reference event is information that the heterogeneous optical fiber measuring apparatus 200 refers to to determine a reference wave used when measuring the optical path. When the heterogeneous optical fiber measuring apparatus 200 transmits a signal to the optical fiber to measure the sample information, the measured sample information may not accurately identify which section of the optical fiber corresponds to which section. Therefore, the operation event detection unit 152 designates a section where the reference event and the resource information of the optical path are mapped to the point managed by the reference wave through the reference event mapping unit 151. In this case, the point managed by the reference wave is an operation event that is used to actually operate the optical path.

The operational data analyzer 153 is a device for analyzing measured data analysis information from the standard data when the standard data is set as the measurement wave by the matching unit 110.

When the standard data is a measurement wave, the failure condition setting unit 154 maps measurement data analysis information analyzing the measurement wave and a specific reference event to set different information as a failure detection condition. The comparison target includes the peak point, the optical core connection point, the ONT section, the optical line termination information, and the insertion loss information of each section mapped with the optical line resource information of the reference wave. The fault detection condition is based on optical line termination information and insertion loss information of each section for optical line short circuit, extension, and optical line aging monitoring information.

The operation event identification unit 155 identifies an operation event that satisfies a failure detection condition as a failure operation event including failure and change information. A fault management event is generated in the form of a fault ticket. The operation event in the form of a trouble ticket includes the same event history information for the current occurrence operation event, along with occurrence time, termination time, occurrence place, occurrence cause, failure level, and occurrence message information such as general failure information. The generated operation event is transmitted to the control management unit 160.

The error information collecting unit 156 collects error information including the maximum, minimum and average deviation information of the measurement result generated according to the operating environment of the heterogeneous optical fiber measuring apparatus 200 when the operation event is detected. When a long-term operation event is detected by the heterogeneous optical fiber measuring apparatus 200, the measurement result is different depending on the characteristics of the heterogeneous optical optical fiber measuring apparatus, the climate, and the operating environment requirements such as the cable management of the critical optical fiber connection point. The error information collecting unit 156 collects error information through the maximum, minimum and average deviation information of the measurement result.

The active threshold calculation unit 157 calculates an active threshold value including an upper / lower limit value to be referenced when generating an operation event and an upper / lower limit value to be referred to when canceling the operation event through error information.

The threshold application unit 158 analyzes a specific threshold set in a specific reference event that does not satisfy the failure detection condition, and applies an active threshold to the analyzed specific threshold. The operational event identification unit checks whether the specific reference event to which the active threshold is applied satisfies the fault detection condition. The threshold application unit 158 generates a failure operation event when the specific reference event to which the active threshold is applied satisfies the failure detection condition. By applying the active threshold as described above, there is an effect that can prevent the failure of the operation event is detected in consideration of the error according to the operating environment.

The control manager 160 delivers the optical fiber information such as measurement information, standard data, reference wave management point, etc. to the operator through a GUI (Graphic User Interface) and a GIS (Geographic Information System).

Hereinafter, the optical fiber integrated management method using the optical fiber integrated monitoring device of the present invention will be described with reference to FIGS. 3 to 8. The description of the foregoing is omitted or briefly described. Prior to the following description, the configuration of the optical path integrated monitoring apparatus of the present invention can be more clearly.

[One. Optical measuring device control]

The matching unit 110 controls the optical path measuring apparatus 200 for measuring the sample information of the optical path, and receives the sample information from the optical path measuring apparatus 200 (S100). 4, the optical path measuring apparatus 200 will be described in more detail.

Referring to FIG. 4, the optical path mapping unit 111 maps an optical switch 300 and an optical path interlocked with the optical path measuring apparatus 200 (S101).

The profile storage unit 112 stores profile information including control parameters and thresholds according to the monitoring environment of the optical fiber network (S102). Meanwhile, the storing of the profile may be performed before the mapping of the light path. Therefore, the order of steps S101 and S102 is not limited to FIG. 4 above.

The profile identification unit 113 identifies specific profile information corresponding to the optical path (S103). Although the profile storage unit 112 includes control parameters and thresholds according to the monitoring environment, there are cases in which the control parameters and thresholds for all monitoring environments are not included.

Therefore, when the specific profile information is not identified by the profile identification unit 113, through the profile setting unit 116 to set another specific profile information including another control parameter and another threshold value according to the characteristics of the optical path (S104). Further parameters and thresholds set by the profile setting unit 116 are stored in the profile storage unit 112.

The signal selection unit 114 selects at least one signal of a reference wave or a measurement wave used in measuring light (S105). On the other hand, the reference wave or the measurement wave may be selected by the operator or automatically selected.

The measurement controller 115 controls the optical path measuring apparatus 200 to measure the optical path according to the specific profile information and the selected specific signal (S106). The measurement controller 115 controls the optical path measuring apparatus 200 according to a heterogeneous connection interface and a protocol. For example, when the protocol of the optical fiber measuring apparatus 200 is TCP / IP, the measurement control unit 115 transmits a control signal to the optical fiber measuring apparatus 200 according to the protocol of TCP / IP.

In addition, the measurement control unit 115 updates state information such as standby, measurement, and completion for the measurement state (S107). For example, when the measurement control unit 115 transmits a control signal to a specific optical fiber measuring device, it updates the specific optical fiber measuring device to the state of 'measurement', and when receiving the sample signal from the specific optical fiber measuring device, the specific optical fiber measuring device To update the status to 'Standby'. Through the state management of the optical fiber measuring apparatus, it is possible to prevent the control signal from being duplicated.

[2. Standard data conversion]

The data conversion unit 120 converts the sample information transmitted from the at least one optical path measuring apparatus 200 into preset standard data (S200). 5 will be described in detail with respect to the standard data conversion method.

Referring to FIG. 5, the data converter 120 receives sample information from the matching unit 100 (S201). The data conversion unit 120 checks whether the standard information is correctly received (S202). When the standard information is not received or an error occurs during the reception, the data converter 120 transmits a control signal to the matching unit 120 to measure the standard information again (S203).

The data conversion unit 120 receives standard information of the heterogeneous optical ray monitoring device from the matching unit 110 (S204). Meanwhile, the data converter 120 receives sample information of various data formats such as standard data, text format, and byte code from the matching unit 100.

Therefore, the data conversion unit 120 checks whether the received sample information is preset standard data (S205). Sample information confirmed as standard data is stored in the data storage unit 130 (S207). For example, when standard data is set to SR4731 of Telcordia, the data converter 120 stores sample information having the data format of SR4731 in the data storage 130.

On the other hand, if the received sample information is not the standard data, the data conversion unit 120 converts the standard information to the data format to satisfy the standard data format (S206).

The standard data stored in the data storage unit 130 is used as management information for confirming the measurement result, and is also used as the measurement history management (S207) information (S207). The measurement history information is used as management data for comparing basic data and measurement data trend for active threshold calculation.

[3. Reference Event Generation]

The reference event unit 140 generates a reference event by analyzing standard data (S300). 6 will be described in more detail with reference event generation.

Referring to FIG. 6, the reference data analyzer 141 identifies standard data stored in the data storage 130 (S301). It is checked whether the identified standard data is a reference wave or a measurement wave by the matching unit 110 (S302).

If the identified standard data is a reference wave, the reference data analysis unit 141 analyzes standard data analysis information from the standard data (S303). Standard data analysis information includes insertion loss, specific peak point, connection point and noise point information of the termination to the optical path.

On the other hand, if the identified standard data is confirmed as a measurement wave to detect the operation event (S500). The operation event detection method will be described later with reference to FIG. 8.

The reference wave determination unit 142 determines whether the analyzed standard data analysis information satisfies a predetermined reference condition referenced to determine the reference wave (S304).

If the standard data analysis information satisfies the reference condition, the reference event generation unit 143 generates a reference event based on the standard data (S308). The reference event includes event information on the optical core connection point of the optical line, the peak point occurring at the optical line resource point, and the optical termination.

The generated reference event is stored as a reference event list in the reference event storage unit (S309).

On the other hand, if the standard data analysis information does not satisfy the reference condition, the reference threshold analysis unit 144 analyzes the application condition of the specific threshold value corresponding to the optical fiber network set by the matching unit 110 (S305). In this case, as a management item for determining an application condition, values such as a connection loss threshold value, a reflection threshold value, an optical termination threshold value, a noise peak level threshold value, and the like may be included.

The reference threshold value determination unit 145 determines whether there is a value for a satisfying measurement interval by determining an application condition for a threshold value (S306). If there is a value for the satisfied measurement section, the condition for generating the reference event is executed again. On the other hand, if the application condition is not satisfied, the reference event is not generated (S307).

[4. Mapping of resource information to reference events

The operation event unit sets a reference wave management point by mapping the resource information and the reference event list with the light beam (S400). The mapping of the optical path resource information and the reference event will be described with reference to FIG. 7. Referring to FIG. 7, the reference event mapping unit 151 checks the reference events stored in the form of a list (S401).

The reference event mapping unit 151 identifies at least one specific reference event mapped with resource information of the optical path in the stored reference event list (S402). When the optical fiber resource information is mapped with the reference event, the point where the reference event exists is the point (X-axis distance and Y-axis loss value) managed by the reference wave. Therefore, the reference event mapping unit 151 sets the point where the reference event matches the resource information of the optical fiber network as the reference wave management point managed by the reference wave (S404). The operation event detection unit 152 detects the reference wave management point as an operation event.

On the other hand, the reference event when the resource information is not mapped with the reference event is deleted or maintained by the operator. If maintained, the reference event is treated as general reference information and managed together with the reference wave information (S403).

The control manager 160 receives and stores the mapped reference event, resource information, and reference wave management point from the operation event unit (S405).

Resource information mapped with the reference event is processed as reference information in the future along with the generalized reference event in accordance with the change of the reference wave (S406).

[5. Failure Operation Event Detection]

The operation event unit 150 compares the reference wave with the measurement wave re-measured by the optical path measurement device 200 and detects an operation event for failure and change of the optical path (S500). Operation event detection will be described in detail with reference to FIG. 8.

Referring to Figure 8, the operational data analysis unit 153 identifies the standard data stored in the data storage unit 130 (S501). The operational data analysis unit 153 checks whether the identified standard data is a reference wave or measurement wave by the matching unit 110 (S502). The operational data analysis unit 153 analyzes the measurement data analysis information from the standard data when the standard data is set as the measurement wave by the matching unit 110 (S503).

When the standard data is a measurement wave, the failure condition setting unit 154 maps measurement data analysis information analyzing the measurement wave and a specific reference event (S504). The failure condition setting unit 154 maps the measurement data analysis information analyzing the measurement wave and the specific reference event to set different information as the failure detection condition (S505). The comparison target includes peak point, optical core connection point, ONT section, optical line termination information and insertion loss information of each section mapped with optical line resource information of reference wave.

The operation event identification unit 155 identifies an operation event that satisfies the failure detection condition as a failure operation event including failure and change information (S509). The identified failure management event is transmitted to and stored in the control management unit 160 (S510).

The threshold application unit 158 analyzes a specific threshold value set for a specific reference event that does not satisfy the failure detection condition (S506).

The threshold application unit 158 applies the active threshold to the analyzed specific threshold (S507). Here, the active threshold is an upper / lower limit value to refer to when generating an operation event and an upper / lower reference value when an operation event is generated through error information generated according to an operation environment of the heterogeneous optical ray measurement apparatus 200 when an operation event is detected. Threshold with lower limit

The operational event identification unit checks whether the specific reference event to which the active threshold is applied satisfies the fault detection condition. If the specific reference event to which the active threshold is applied satisfies the failure detection condition, the control unit regenerates the failure management event, and if the detection condition is not satisfied, the failure operation event is not generated (S508).

The control management unit 160 provides a stored operation event as a function such as a GUI and a GIS map so that the operator can be audited / visually.

The present invention integrates the connection interface and protocols of various optical line monitoring devices for monitoring various optical networks such as backbone and subscriber network (PON), establishes the management point of the optical line through the reference wave, and measures the measurement wave. It can be applied to the integrated management system for the optical path through which the failure and change of the optical path can be detected.
