[0055] In the above technical solution, the monitoring and optimization process of the measurement state change of the optical cable in the digital monitoring system for highway optical cables is realized through the positioning module, distribution module, fusion module, monitoring module, monitoring module and feedback module; specifically, the positioning module is set to determine the spatial position of the highway optical cable, optimize the optical cable image environment, specifically determine the layer position of the highway optical cable through GIS, and then determine and obtain the spatial positioning information of the optical cable; the distribution module is set to analyze the optical cable fault, determine the optical cable fault environment through the BIM model, and determine the distribution information of the optical cable fault environment; the fusion module is set to fuse the spatial positioning information of the optical cable determined through GIS and the distribution information of the optical cable fault environment obtained by BIM to realize the determination of the monitoring points; the monitoring module is used to ensure that the optical cable measurement analysis is carried out according to the pre-determined monitoring points, and the monitoring results are obtained by judging the optical cable measurement, so as to accurately determine the position of the optical cable fault state; finally, the feedback module is set to analyze the measurement accuracy of the fault of the monitoring points, specifically generate a warning signal according to the judged monitoring results and feed back to adjust the monitoring points.

[0056] As an implementation manner of the present invention, the spatial positioning information of the optical cable includes:

[0057] Obtaining the geographical spatial data of the highway optical cable through GIS;

[0058] Determine the distribution position images of each access site based on the access sites of historical highway optical cables;

[0059] Construct an optical cable spatial network system model based on the geospatial data of highway optical cables;

[0060] Input the distribution position images of each access site into the optical cable spatial network system model to determine the layer where the highway optical cable is located in space and record the number of layers.

[0061] In the above technical solution, the specific content of obtaining the optical cable spatial positioning information includes first obtaining the geospatial data of highway optical cables through GIS. Specifically, by using the optical cable inspection subsystem, based on GIS geographic information technology, methods such as manual inspection are adopted to timely discover the external geographic information of the optical cable, obtain the real-time status and position information of the optical cable from the geographic information, and present and manage it on the GIS map. Then, for the optical cable access sites obtained from the GIS map, the optical cable access site is an optical fiber distribution site. Therefore, the access sites of the entire current optical cable line include communication base stations, optical distribution cabinets, and data centers, etc. Next, a network system is constructed by inputting the geospatial data of highway optical cables into GIS. Specifically, the optical cable route, position, and connection points are determined based on the geospatial data, and a map of the area where the optical cable is distributed, which includes geographic information such as topography and administrative divisions, is imported into GIS. Then, according to the imported geospatial data information including the optical cable connection relationship and route, the topological structure of the optical cable spatial network is constructed, mainly based on each access point of the optical cable; the optical cable spatial network system model is mainly composed of a network topology modeling module, a spatial analysis modeling module, and a mathematical model modeling module. Finally, by inputting the distribution position images of each access site into the optical cable spatial network system model for information confirmation, the confirmed information is the layer where the highway optical cable is located in space. After recording the number of layers, it is output.

[0062] As an implementation manner of the present invention, the distribution module includes:

[0063] Preset the geometric center of the building as the center of the circle, and set the distance from the historical accident points of the highway optical cable around the building to the geometric center of the building as the radius of the radiation circular area;

[0064] Import the surrounding building images of the highway optical cable and their corresponding radiation circular areas into the BIM model to obtain the three-dimensional coordinate information of the optical cable fault environment distribution information.

[0065] In the above technical solution, the distribution module is used to confirm the optical cable and the surrounding building environment. By confirming the distribution information of the optical cable fault environment, the fault position information and the output process in the space of the optical cable are realized. Specifically, first, the geometric center of the building is confirmed, and the positional relationship between the optical cable fault and the building is confirmed. By setting the geometric center of the building as the center of the circle and setting the distance from the historical accident point of the optical cable around the building to the geometric center of the building as the radius of the radiation circular area for confirmation, and then the three-dimensional import of the BIM model is carried out for the surrounding building images and the settings of the radiation circular area, and the fault environment distribution information is obtained according to it; since the input is the building image and the radiation circle, the output environment distribution information includes the three-dimensional coordinate information of the fault position image.

[0066] As an implementation manner of the present invention, the three-dimensional coordinate information of the optical cable fault environment distribution information includes:

[0067] Determine each fault point position;

[0068] Connect each fault point position by the triangular network construction method to form a grid space polygon;

[0069] Monitor and judge the number M of target buildings falling within the grid space;

[0070] Record the minimum value of the central distance from the fault point to the target building as the fault response distance.

[0071] In the above technical solution, the process of obtaining the three-dimensional coordinate information of the optical cable fault environment distribution is mainly as follows: first, determine each fault point position information, and connect each fault point position by the triangular grid construction method to construct a spatial structure. The constructed grid space is a topological structure of a polygon; then monitor, regard the buildings falling within this space as target buildings, and record the number M of this target building; at the same time, judge the three-dimensional distance between the marked fault point position and the center point of the target building within this space as the fault response distance, and the fault response distance reflects the feedback distance of the monitoring station that can be arranged in this building from the fault point.

[0072] As an implementation manner of the present invention, the process of the fusion module realizing information fusion includes:

[0073] Extract the layer information of the spatial position where the highway optical cable is located, and determine the optical cable element data;

[0074] Combine the fault response distance parameter of the current layer according to the current layer number where the highway optical cable is located;

[0075] Import the optical cable element data and the fault response distance parameter into the BIM model and perform machine pre-training to construct an optical cable fault distribution model;

[0076] Import historical optical cable fault data and optical cable fault spatial points into the pre-trained optical cable fault distribution model to output deviation parameters, obtain candidate relay station information based on the deviation parameters, and determine monitoring points.

[0077] In the above technical solution, the fusion module extracts the optical cable spatial positioning information obtained from GIS and the optical cable fault environment distribution information extracted using the BIM model; extracts the optical cable information data in the optical cable spatial positioning information using the optical cable curve analysis technology; and determines the optical cable BIM three-dimensional fault data through the information of the optical cable fault environment distribution, and then constructs the fault response distance data of the optical cable by constructing a triangular network in the network space; combines the optical cable information data and the fault response distance data to construct an optical cable fault distribution model based on the BIM model. Specifically, first, extract the layer information of the spatial position where the highway optical cable is located, and then process it through an optical time domain reflectometer (OTDR) and perform transformation and denoising processing using a wavelet function to determine the optical cable element data; and combine the fault response distance parameter of the current layer where the highway optical cable is located to obtain the fault response distance parameter of the current layer. The fault response distance in this layer is a two-dimensional mapping of the optical cable space (assuming the height of a single optical cable is consistent) from the three-dimensional space, so the fault response distance parameter is a length data.

[0078] Furthermore, import the optical cable element data and the fault response distance parameter into the BIM model and perform machine pre-training to construct an optical cable fault distribution model; then import historical optical cable fault data and optical cable fault spatial points into the pre-trained optical cable fault distribution model to output deviation parameters, obtain candidate relay station information based on the deviation parameters, and determine monitoring points.

[0079] As an implementation manner of the present invention, the monitoring module performs optical cable measurement and analysis including:

[0080] Through the formula Calculate to obtain the fault coefficient of the th monitoring point;

[0081] wherein, is the position coefficient of the th monitoring point; is the coordinate of the record ; is the coordinate of the record ; is the coordinate of the record ; is the coordinate of the record ; is the fault response distance of the record To record the fault response distance; is the distance detected by the optical time domain reflectometer or the optical fiber length; is the distance from the th monitoring point to the computer room where the relay station is located;

[0082] In the above technical solution, during the process of obtaining the monitoring points, it is necessary to perform parameter setting, data acquisition, and curve analysis on the optical cable fault distribution model. The parameter setting includes pre-setting the position coefficient of the monitoring points. The position coefficient is obtained by pre-clustering calculation based on the historical data of the current monitoring points. The calculation formula is ; where is the number of triangles in the figure, is the reading of the monitoring point.

[0083] By judging the relationship between the true fault distance calculated by using the optical cable fault location algorithm and the position of the relay point, it is possible to quickly determine the precise location of the optical cable fault point by judging the magnitude of the fault coefficient.

[0084] As an implementation manner of the present invention, the monitoring result is:

[0085] Compare the fault coefficient with the standard fault coefficient threshold interval of the preset optical cable fault point information:

[0086] If < , then find the corresponding spatial data through the geographical identification code to determine the location of the optical cable fault point;

[0087] If , then find the corresponding spatial data through the geographical identification code to determine the location of the optical cable fault point;

[0088] If > , then find the corresponding spatial data through the geographical identification code to determine the location of the optical cable fault point.

[0089] In the above technical solution, when it is determined that the fault coefficient obtained in real time falls within the standard threshold interval determined during the training process of the optical cable fault distribution model trained based on the input historical data, it is determined that the spatial data corresponding to the position recognition directly according to the current monitoring point can confirm the fault point position of the optical cable. Otherwise, it is necessary to adjust the monitoring point and identify by swapping the geographical identification code of the distance from the adjusted monitoring point to the relay station; specifically, if belongs to the interval inside, then find the corresponding spatial data through the geographical identification code to determine the fault point position of the optical cable; if < , then find the corresponding spatial data through the geographical identification code to determine the fault point position of the optical cable; otherwise, find the corresponding spatial data through the geographical identification code to determine the fault point position of the optical cable.

[0090] As an implementation manner of the present invention, the way for the feedback module to generate a warning signal according to the monitoring result and feedback to adjust the monitoring point is:

[0091] If , then generate a warning signal; further:

[0092] If < , then reduce the preset number of relay stations and cancel the current monitoring point;

[0093] If > , then increase the preset number of relay stations and cancel the current monitoring point.

[0094] In the above technical solution, further, for the situation that does not belong to the threshold interval, a warning signal is generated, and it is determined that if < , then reduce the preset number of relay stations and cancel the current monitoring point; conversely, if > , then increase the preset number of relay stations and cancel the current monitoring point; realizing the adjustment and optimization process of the monitoring point.
