[0019] See also Figure 1 As shown, the present invention is a highway optical cable digital monitoring system, comprising: The positioning module is used to determine the layer of the highway optical cable through GIS to obtain the optical cable spatial positioning information; A distribution module is used to determine the optical cable fault environment distribution information of the highway optical cable through the BIM model; A fusion module is used to fuse the optical cable spatial positioning information and the optical cable fault environment distribution information to determine the monitoring point; The monitoring module is used to measure and analyze the optical cable according to the monitoring points and determine the monitoring results; The feedback module generates early warning signals based on the monitoring results and provides feedback to adjust the monitoring points.

[0020] In the above technical scheme, the monitoring and optimization process of the optical cable measurement state change of the highway optical cable digital monitoring system 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 and optimize the optical cable image environment. Specifically, the layer position of the highway optical cable is determined through GIS, and then the optical cable spatial positioning information is determined; the distribution module is set to analyze the optical cable fault, and the optical cable fault environment is determined through the BIM model to determine the distribution information of the optical cable fault environment; the fusion module is set to fuse the optical cable spatial positioning information determined by GIS and the optical cable fault environment distribution information obtained by BIM to realize the determination of the monitoring point; the monitoring module ensures that the optical cable measurement and analysis is carried out according to the predetermined monitoring point, and the monitoring results are obtained through the optical cable measurement judgment to realize the accurate determination of the position of the optical cable fault state; finally, the fault measurement accuracy of the monitoring point is analyzed by setting the feedback module, specifically, the early warning signal is generated according to the judgment of the monitoring result and the monitoring point is adjusted by feedback.

[0021] As an implementation mode of the present invention, the optical cable spatial positioning information includes: Obtain geospatial data of highway optical cables through GIS; Determine the distribution location image of each access site based on the access sites of historical highway optical cables; Construct a fiber optic cable spatial network system model based on the geographic spatial data of highway fiber optic cables; The images of the distribution locations of each access site are input 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.

[0022] In the above technical scheme, the specific content of obtaining the spatial positioning information of the optical cable includes first obtaining the geographic spatial data of the highway optical cable through GIS, specifically, by using the optical cable inspection subsystem, based on GIS geographic information technology, and using methods such as manual inspection to timely discover the external geographic information of the optical cable, obtain the real-time status and location information of the optical cable from the geographic information, and present and manage it on the GIS map. Then, the optical cable access site obtained in the GIS map is a fiber distribution site, so the access site of the entire line of the current optical cable includes communication base stations, optical distribution power and data centers. Then, by inputting the geographic spatial data of the highway optical cable into the GIS to construct the network system, specifically determine the direction, location and connection point of the optical cable with the geographic spatial data, and import a map of the area where the optical cable is distributed into the GIS, a map containing geographical information such as topography, administrative divisions, etc., and then construct the topological structure of the optical cable space network according to the imported geographic spatial data information including the connection relationship and direction of the optical cable, mainly based on the access points of the optical cable; the optical cable space network system model is mainly composed of a network topology modeling module, a spatial analysis modeling module and a mathematical model modeling module. Finally, the information is confirmed by inputting the distribution position images of each access site into the optical cable space network system model. The confirmed information is the layer of the spatial position of the highway optical cable, and the number of layers is recorded and output.

[0023] As an embodiment of the present invention, the distribution module includes: The geometric center of the building is set in advance as the center of the circle, and the distance from the historical accident point of the highway optical cable around the building to the geometric center of the building is set as the radius of the radiating circular area; The surrounding building images of the highway optical cable and its corresponding radiating circular area are imported into the BIM model to obtain the three-dimensional coordinate information of the optical cable fault environment distribution information.

[0024] In the above technical scheme, the distribution module is used to confirm the optical cable and the surrounding building environment, and the fault location information and output process in the optical cable space are confirmed by confirming the optical cable fault environment distribution information. Specifically, the geometric center of the building is first confirmed, and the positional relationship between the optical cable fault and the building is confirmed. The geometric center of the building is set as the center of the circle, and the distance from the historical accident point of the highway optical cable around the building to the geometric center of the building is set as the radius of the radiation circular area for confirmation. Then, the surrounding building image and the setting of the radiation circular area are three-dimensionally imported into the BIM model, and the fault environment distribution information is obtained based on 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 location image.

[0025] As an implementation mode of the present invention, the three-dimensional coordinate information of the optical cable fault environment distribution information includes: Determine the location of each fault point; Each fault point is connected by a triangulated network construction method to form a grid space polygon; Monitor and determine the number M of target buildings that fall within the grid space; The minimum value of the distance from the fault point to the center of the target building is recorded as the fault response distance.

[0026] In the above technical solution, the process of obtaining the three-dimensional coordinate information of the distribution of the optical cable fault environment is mainly as follows: first, determine the information of each fault point, connect each fault point through the triangular grid construction method to realize the construction of the spatial structure, and the constructed grid space is a polygonal topological structure; then monitor, take the buildings falling in the space as target buildings, and record the number M of the target buildings; at the same time, through the three-dimensional distance between the marked fault point and the center point of the target building in the space, judge the distance as the fault response distance, and the fault response distance reflects the feedback distance between the monitoring station that can be arranged for the building and the fault point.

[0027] As an implementation mode of the present invention, the process of realizing information fusion by the fusion module includes: Extract the layer information of the spatial location of the highway optical cable and determine the optical cable element data; The fault response distance parameter of the current layer is obtained by combining the layer number of the current layer where the highway optical cable is located; Import the optical cable element data and fault response distance parameters into the BIM model for pre-training to build an optical cable fault distribution model; The historical optical cable fault data and the spatial locations of optical cable faults are imported into the pre-trained optical cable fault distribution model to output deviation parameters. The candidate relay site information is obtained according to the deviation parameters to determine the monitoring locations.

[0028] In the above technical solution, the fusion module extracts the optical cable spatial positioning information obtained by GIS and the optical cable fault environment distribution information extracted by BIM model; uses the optical cable curve analysis technology to extract the optical cable information data in the optical cable spatial positioning information; and determines the optical cable BIM three-dimensional fault data through the information of the optical cable fault environment distribution, and then uses the triangular network to construct the network space to obtain the fault reaction distance data of the optical cable; combines the optical cable information data and the fault reaction distance data to realize the construction of the optical cable fault distribution model based on the BIM model. Specifically, first extract the layer information of the spatial position of the highway optical cable, and then process it through the optical time domain reflectometer (OTDR) and perform wavelet function transformation and denoising to determine the optical cable element data; and combine the current layer number of the highway optical cable to obtain the fault reaction distance parameter of the current layer, and the fault reaction distance in the layer is two-dimensionally mapped from the three-dimensional space to the optical cable space (assuming that the height of a single optical cable is consistent), so the fault reaction distance parameter is the length data.

[0029] Furthermore, the optical cable fault distribution model is constructed by importing the optical cable element data and fault response distance parameters into the BIM model for pre-training; then the historical optical cable fault data and the optical cable fault spatial points are imported into the pre-trained optical cable fault distribution model to output the deviation parameters, and the candidate relay site information is obtained according to the deviation parameters to determine the monitoring points.

[0030] As an implementation mode of the present invention, the monitoring module performs optical cable measurement and analysis including: By formula: Calculate the first Failure coefficient of each monitoring point ; in, For the The location coefficient of each monitoring point; For the record of coordinate; For the record of coordinate; For the record of coordinate; For the record of coordinate; For the record Fault response distance; For the record Fault response distance; The distance or fiber length detected by the optical time domain reflectometer; For the The distance from each monitoring point to the computer room where the relay site is located; For the The distance from each monitoring point to the computer room where the relay site is located.

[0031] In the above technical solution, in the process of acquiring 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 presetting the location coefficient of the monitoring point. The location coefficient is obtained by pre-clustering calculation based on the historical data of the current monitoring point. The calculation formula is: ;in, is the number of triangles in the graph, It is the reading of the monitoring point.

[0032] By judging the relationship between the actual fault distance and the relay point position calculated using the optical cable fault location algorithm, the precise location of the optical cable fault point can be quickly determined by judging the size of the fault coefficient.

[0033] As an implementation mode of the present invention, the monitoring result is: The failure factor The standard fault coefficient threshold interval with the preset optical cable fault point information To compare: like < , then through The geographic identification code finds the corresponding spatial data and determines the location of the optical cable fault point; like , then through The geographic identification code finds the corresponding spatial data and determines the location of the optical cable fault point; like > , then through The geographic identification code finds the corresponding spatial data and determines the location of the optical cable fault point.

[0034] In the above technical solution, when the fault coefficient obtained in real time falls within the standard threshold interval determined in the training process of the optical cable fault distribution model according to the input historical data, it is determined that the spatial data corresponding to the position identification is directly performed according to the current monitoring point, and the fault point location of the optical cable can be confirmed. Otherwise, the monitoring point needs to be adjusted, and the geographical identification code of the distance from the adjusted monitoring point to the relay site is replaced for identification; specifically, if Belong to the interval Within, through The geographic identification code finds the corresponding spatial data and determines the location of the optical cable fault point; if < , then through The geographic identification code finds the corresponding spatial data and determines the location of the optical cable fault point; otherwise, The geographic identification code finds the corresponding spatial data and determines the location of the optical cable fault point.

[0035] As an implementation mode of the present invention, the feedback module generates an early warning signal according to the monitoring result and feeds back to adjust the monitoring point in the following manner: like , then a warning signal is generated; further: like < , then reduce the number of preset relay sites and cancel the current monitoring point; like > , then increase the number of preset relay sites and cancel the current monitoring point.

[0036] In the above technical solution, further, for the situation that does not belong to the threshold interval, an early warning signal is generated, and it is determined if < , then reduce the number of preset relay sites and cancel the current monitoring point; on the contrary, if > , then increase the number of preset relay sites and cancel the current monitoring points; realize the adjustment and optimization process of monitoring points.

In particular, for the device, equipment, and non-volatile computer storage medium embodiments, since they are basically similar to the method embodiments, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
