[0037] As Figure 1 shown, in the first aspect, the present application provides a data management platform for the four major railway electrical interfaces, including a standard management module, a system module, and an interface detection module.

[0038] Among them, the standard management module has a database of railway four major electrical interface data.

[0039] Specifically, the four major railway electricals are the general term for communication, signal, power, and power traction supply projects. The interfaces to be realized in the present application are not the interfaces of line plug-ins, but the interfaces between components in the four major railway electricals. This interface includes standardized dimensional parameters, etc. For example, the column and the base on the railway are two components, and the docking position between the two components is the interface.

[0040] During the railway construction process, all possible interfaces are formed into interface data, and the interface data is combined to form a database for easy calling.

[0041] The system module is connected to the standard management module and is used to retrieve the data in the database to form a work task. Among them, the work task carries the railway four major electrical interface data in the database.

[0042] Specifically, the system module includes a positioning unit and a task unit.

[0043] Among them, the positioning unit is used to position the area where the work task is executed to form a coordinate range. That is to say, the unit can mark the coordinate of the work task area to be executed. In this way, each worker can know their own work area when performing the work task. It can be understood that the railway construction section map is divided into several areas by the positioning unit, and several areas refer to the areas where workers can complete the daily workload. Exemplarily, the railway construction section map is 100 meters, and there are several railway four-electrical interfaces in these 100 meters. Each worker can complete 10 meters per day, so each area is 10 meters.

[0044] The task unit is connected to the positioning unit and the standard management module, and is used to retrieve the data in the database to form a work task, and load the coordinate range into the work task to form a work task with a coordinate range. Among them, the work task includes multiple task points, and each task point represents an interface of the railway four-electrical. The task unit can retrieve the corresponding standardized railway four-electrical interface data in the database according to the work task. That is to say, the work task includes the work scope and the standardized data of the railway four-electrical interfaces within the work scope. In this way, the worker can know their own work scope through the work task, and when detecting the current railway four-electrical interface, compare the obtained current railway four-electrical interface data with the standardized railway four-electrical interface data to determine the accuracy of the railway four-electrical interface within the work scope.

[0045] The interface detection module is respectively connected to the system module and the standard management module, and is used to detect the current railway four-electrical interface according to the work task, form a detection result, and feedback it to the system module.

[0046] Specifically, the interface detection module includes an interface detection unit, an interface comparison unit, and a data transmission unit.

[0047] Among them, the interface detection unit includes an industrial camera and a laser scanner, which are respectively used to obtain the interface data of the current railway four-electrical interface and transmit it to the interface comparison unit. Among them, the interface data includes the interface contour three-dimensional point cloud data and the image data of the surface texture and color. That is to say, through the shooting of the industrial camera and the scanning of the laser scanner, the image data of the surface texture and color and the interface contour three-dimensional point cloud data are obtained correspondingly. The combination of these two different types of data reproduces the size of the current railway four-electrical interface. It should be noted that the industrial camera and the laser scanner can be integrated on intelligent electronic devices, such as mobile phones, tablets, etc.

[0048] The interface comparison unit is configured to receive the interface data, compare the interface data with the railway signal, power supply, communication, and integration interface data in the work task, form a detection result, and send it to the data transmission unit. That is to say, the current railway signal, power supply, communication, and integration interface reproduced from the interface data is compared with the standardized railway signal, power supply, communication, and integration interface to form a detection result. The comparison method can be feature comparison.

[0049] The data transmission unit is configured to send the detection result to the system module. The data transmission unit can be a conventional wireless transmission module.

[0050] It should be noted that the interface comparison unit is further configured to identify the interface data to obtain master control interface data and non-master control interface data. If the detection result formed by comparing the master control interface data with the railway signal, power supply, communication, and integration interface data in the work task is qualified, the detection result is sent to the data transmission unit; otherwise, the interface detection unit is configured to obtain the interface data of the rectified railway signal, power supply, communication, and integration interface and transmit it to the interface comparison unit; the interface comparison unit is further configured to compare the master control interface data of the rectified railway signal, power supply, communication, and integration interface with the railway signal, power supply, communication, and integration interface data in the work task to form a detection result.

[0051] Specifically, after the interface data is identified by the interface comparison unit, master control interface data and non-master control interface data are obtained. The master control interface data represents an interface that plays a basic functional role and does not affect the project quality, and the non-master control interface data represents an interface that can optimize the master control interface and achieve a better effect. That is to say, even without the non-master control interface, the basic function of the master control interface will not be affected.

[0052] The data of both the master control interface and the non-master control interface have been pre-standardized through the database. That is to say, in the database, clear standardized definitions have been made for which data in the railway signal, power supply, communication, and integration interface are master control interface data and which are non-master control interface data. In this way, after the interface data is identified in the interface comparison unit, the master control interface data field is compared with the railway signal, power supply, communication, and integration interface data in the database called in the work task to obtain a detection result. If the detection result is greater than or equal to the preset threshold, the detection result is determined to be qualified, and the detection result is sent to the data transmission unit. If the detection result is less than the preset threshold, it is determined that the master control interface data does not meet the requirements, and the current railway signal, power supply, communication, and integration interface needs to be rectified. After the rectification, the interface data of the rectified railway signal, power supply, communication, and integration interface is obtained again through the interface detection unit and transmitted to the interface comparison unit for comparison until the detection result is qualified.

[0053] In one embodiment, the interface detection module further includes an adjustment unit.

[0054] Among them, the adjustment unit is connected to the interface comparison unit, and is used to adjust the work task to form adjustment data and send it to the interface comparison unit.

[0055] The interface detection unit will obtain the interface data of the current railway signal, power supply, communication, and integration interface and transmit it to the interface comparison unit.

[0056] The interface comparison unit compares the interface data of the current railway signal, power supply, communication, and integration interface with the adjustment data to form an adjustment detection result, and sends the adjustment detection result to the data transmission unit.

[0057] It should be noted that when the staff is actually operating on-site, if errors, omissions, etc. are found in the records on the drawings, the adjustment unit can be used to make on-site adjustments, thereby forming adjustment data and sending it to the interface comparison unit. Next, the interface detection unit is used to obtain the interface data of the current railway signal, power supply, communication, and integration interface and transmit it to the interface comparison unit for comparison. When the staff makes adjustments to the work task on-site, a request is sent to the system module through the data transmission unit. After the system module calls the interface data through the database, it is sent down to the interface comparison unit. In this way, it can be ensured that the adjustment data in the interface comparison unit is standardized interface data.

[0058] It should also be noted that since most of the work on the railway section is outdoors and in remote areas, the signal is often poor. In this case, the database can be pre-loaded into the staff's handheld terminal, such as a handheld all-in-one machine, but encryption processing is required. Next, the adjustment unit only needs to send the instruction data formed by the adjustment data to the system module of the headquarters. After receiving the instruction data, the system module only needs to send the corresponding instruction to the handheld terminal. After receiving the corresponding instruction, the handheld terminal can decrypt the corresponding interface data in the database through the decryption information in the corresponding instruction. The decrypted corresponding interface data will be used by the interface comparison unit.

[0059] Finally, it should be noted that blockchain technology is pre-loaded between the system module and the handheld terminal. In this way, each adjustment data will leave a record, forming an unmodifiable timestamp and action, which is convenient for subsequent re-inspection and traceability. Blockchain technology is a conventional technology, and this application does not limit which blockchain technology to use.

[0060] As Figure 2 shown, in the second aspect, the present application provides a method for inspecting a railway signal, power supply, communication, and integration interface data management platform, which is applied to the aforementioned railway signal, power supply, communication, and integration interface data management platform. The method includes: S100, obtaining the work task issued by the system module.

[0061] Among them, the work task carries railway signal, power, communication and integration interface data, and the railway signal, power, communication and integration interface data is retrieved from a database with railway signal, power, communication and integration interface data.

[0062] Specifically, step S100 may include the following steps: S101, obtain a railway construction section map, and divide it into several regions according to the daily workload, where each of the regions has a coordinate range.

[0063] Specifically, the railway construction section map is pre-constructed, and the daily workload represents the work that a worker can complete per day. Obtain the workload completed by the worker on a historical day, and divide the railway construction section map into several regions according to the workload completed on the historical day, so as to ensure that the divided regions are work tasks that the worker can complete in a single day. After dividing several regions, determine the regional coordinates according to the regions. In this way, the worker can know the scope of his work on the day according to the regional coordinates.

[0064] It should be noted that the division of the railway construction section map may include the following steps: Obtain the average number of processing area interfaces of the worker in the historical N days, the maximum scanning distance of the handheld terminal in a single day, and the data obtained by the GIS system, such as terrain complexity factors such as slope and obstacle density data obtained by the GIS system.

[0065] Adopt weighted K-means clustering. The execution of the clustering algorithm is a conventional method, and this application does not limit it. The objective function Minimize is: ; Among them, , represents the total number of divided regions, , represents the th number of interfaces in the region, , represents the maximum scanning distance of the handheld terminal in a single day, , represents the th terrain complexity factor of the region (dimensionless, value range [0,1]), , represents the th area of the region, and , represents the weight coefficient (satisfying ). By adjusting the and ratio, the algorithm can be controlled to focus on work efficiency optimization ( item) or construction difficulty balance ( item). For example: construction in mountainous areas (complex terrain): set =0.7, =0.3; construction in plains (simple terrain): set = 0.3, = 0.7。

[0066] Through the objective function, the coordinates of the geofence are obtained, and the division of the railway construction section map is dynamically adjusted according to the geofence coordinates.

[0067] S102. According to the several regions, retrieve the railway four-electrical interface data in the database to form the work task, and load the coordinate range into the work task to obtain a work task with a coordinate range.

[0068] Among them, the work task includes multiple task points.

[0069] Specifically, after determining the work task, retrieve the railway four-electrical interface data in the database according to the work task to form the work task. In addition, coordinates are configured for each task point in the work task. In this way, when workers complete the task, they can also record the coordinates to avoid problems caused by differences in the positions of task points. It should be noted that the railway construction section may be in areas with poor signals such as tunnels and valleys. Therefore, the database can be pre-loaded into the handheld terminal and encrypted. So that in the case of poor signals, the database can be directly called on the handheld terminal. The decryption of the database can be achieved by means of face recognition or the system module issuing a decryption instruction. When the database is decrypted, the railway four-electrical interface data in the database can be called.

[0070] It should be noted that the offline data security mechanism for the database can be implemented through the following methods: Data encryption: Use the national secret SM4 algorithm to encrypt the offline package, and the key is generated by the system module through quantum random numbers; Device binding: Write the hash value of the device fingerprint (CPU serial number + base station ID) into the encrypted packet header; Decryption conditions: Geofence verification: The GPS coordinates need to be within the specified number of meters in the task area, such as within 500 meters; Time window limit: The decryption validity period is the specified time of the task, such as 24 hours after issuance; Biometric verification: It is necessary to pass the authentication of the live detection factor.

[0071] S200. According to the work task, detect the current railway four-electrical interface to obtain a detection result.

[0072] Furthermore, the S200 step may further include the following steps: S201. Obtain the interface data of the current railway four-electrical interface.

[0073] Among them, the interface data includes three-dimensional point cloud data of the interface contour and image data of the surface texture and color.

[0074] Specifically, for the acquisition of interface data, the devices used in the aforementioned railway signal, power supply, communication, and SCADA interface data management platform can be employed, which will not be elaborated here.

[0075] It should be noted that for the collected three-dimensional point cloud data and image data of surface texture and color, time synchronization is carried out. For example, microsecond-level synchronization between the scanner and the camera is achieved through PTP (Precision Time Protocol) to ensure the spatial alignment of the point cloud and the image, so that the formed three-dimensional model can have corresponding surface texture and color.

[0076] S202: Using the three-dimensional point cloud data, obtain the three-dimensional model of the current railway signal, power supply, communication, and SCADA interface.

[0077] For the construction of the three-dimensional model from the three-dimensional point cloud data, conventional methods can be used. For example, the Poisson reconstruction algorithm is adopted with a reconstruction depth (Octree Depth) = 10 (corresponding to a voxel resolution of 0.001m), a sample spacing = 0.002m, a surface smoothness = 0.8, and a hole repair threshold = 0.05m² (holes with an area smaller than this value are automatically filled).

[0078] S203: Using the image data of surface texture and color, obtain the surface features of the current railway signal, power supply, communication, and SCADA interface.

[0079] For the image data of surface texture and color, conventional feature processing methods can be used. For example, the Local Binary Pattern (LBP) is used to analyze the surface texture consistency, identify the analysis area, and the Uniform Local Binary Pattern is adopted with a neighborhood radius R = 3 pixels, a sampling point number P = 8, a feature histogram bin number = 59 (corresponding to the number of uniform pattern types), and rotation invariance processing: calculate the minimum rotation equivalent representation for each LBP feature value.

[0080] S204: According to the three-dimensional model and the surface features of the current railway signal, power supply, communication, and SCADA interface, obtain the feature representation data of the current railway signal, power supply, communication, and SCADA interface.

[0081] Based on the three-dimensional model and the surface features, the weighted stitching method is carried out (the geometric feature weight of the three-dimensional model is 0.6, and the surface feature weight is 0.4) for feature fusion, thereby obtaining the feature representation data of the current railway signal, power supply, communication, and SCADA interface. Next, normalization transformation is performed on the feature representation data of the current railway signal, power supply, communication, and SCADA interface for comparison with the features of the standardized railway signal, power supply, communication, and SCADA interface data in subsequent steps.

[0082] S205: Compare the feature representation data with the features of the railway signal, power supply, communication, and SCADA interface data in the work task to obtain the detection result.

[0083] Compare the feature representation data of the normalized current railway four-electrical interface with the features of the railway four-electrical interface data in the work task to perform feature difference comparison, so as to obtain the detection result. For the feature comparison, conventional feature comparison methods can be used, and the present application does not limit this.

[0084] It should be noted that due to various reasons such as comparison, there will be differences between the detection result and the actual result. For example, during the detection process, when comparing the feature representation data of the current railway four-electrical interface with the features of the railway four-electrical interface data in the work task, it is found that there are 3 differences. That is to say, in the case of differences, the following steps are also included: Construct a selection box; Obtain the edge of the feature difference, and based on the edge of the feature difference, obtain the edge coordinates of the feature difference; According to the edge coordinates of the feature difference, construct a regular box, where the regular box can be circular or rectangular, etc. The regular box can frame the feature difference.

[0085] Present the regular box on the three-dimensional model of the current railway four-electrical interface to obtain a three-dimensional model with a regular box.

[0086] In this way, the staff can view the feature differences based on the photo formed by the three-dimensional model or directly on the three-dimensional model, which is not only convenient for the staff to understand in a timely manner, but also if the problem of the railway four-electrical interface is small, it can be processed on site so that the railway four-electrical interface meets the requirements. The presentation method can be presented through a display, for example, the display on a scanner, etc.

[0087] The feature difference here refers to the position where the feature of the current railway four-electrical interface is located. Because there are differences between the feature of the current railway four-electrical interface and the features of the railway four-electrical interface data in the work task, therefore, the position where the feature of the current railway four-electrical interface is located is edge-marked to form the edge of the feature difference.

[0088] It should be noted that the selection box is constructed as a layer on the three-dimensional model, so that it will not affect the three-dimensional model.

[0089] In addition, the marking box adopts a color grading mechanism: the red box represents the main control item that affects the structural safety (such as the offset of the grounding terminal), the yellow box represents the secondary control item that affects the function (such as the misalignment of the sealing ring), and the blue box represents the appearance problem (such as the coating scratch). This hierarchical visualization processing ensures the integrity of the original detection data and provides intuitive difference positioning at the same time.

[0090] After the annotation box is generated, the pre-set engineering knowledge base is retrieved. A solution card is dynamically generated on the right side of the annotation box. The card contains three key pieces of information: the first line is the disposal solution (such as "Need to re-drill and tap"), the second line is the impact level (such as "Level A: Affects lightning protection and grounding"), and the third line is the urgency level (such as "Handle within 24 hours"). Among them, the data in the engineering knowledge base can be sourced from historical maintenance cases. For example, for common problems such as bolt hole position deviation, the system will give priority to recommending standardized repair solutions such as reaming and bushings.

[0091] It should be noted that an index can be constructed for the engineering knowledge base, which can be a coding index. The coding has a unique ID. The coding is loaded into the characteristics of the railway four-electrical interface data in the work task.

In addition, for the second line of impact level and the third line of urgency level, a mapping relationship can be formed with the standardized repair solution.

[0092] S206, send the detection result to the system module through the data transmission unit.

[0093] When transmitting through the data transmission unit, the transmission protocol used is a conventional protocol, and this application does not limit the protocol.

[0094] Specifically, the step of S206, sending the detection result to the system module through the data transmission unit, may include the following steps: S2061, identify the interface data to obtain the main control interface data and the non-main control interface data.

[0095] Specifically, for the method of identifying interface data, a convolutional neural network model with an appropriate carrier volume is pre-added in the interface comparison unit. This convolutional neural network model is a trained model, such as the ResNet-18 model. The three-dimensional model formed by the interface data is converted into an image, such as an orthographic projection image, and then the image is used as the input and input into the convolutional neural network model for identification, so as to obtain the main control interface data and the non-main control interface data.

[0096] S2062, if the detection result of the main control interface data is greater than or equal to the preset threshold, the detection result is qualified, and the detection result is sent to the system module through the data transmission unit; Otherwise, obtain the interface data of the current railway signal, power supply, communication, and SCADA interface after rectification, and perform comparison until the master control interface data is greater than or equal to the preset threshold.

[0097] It should be noted that the definition of the master control interface: Core components related to structural safety (such as grounding terminals and load-bearing brackets) can be determined according to the relevant standards of railway signal, power supply, communication, and SCADA projects.

[0098] After determining the master control interface data, compare the detection result of the master control interface data with the preset threshold to obtain qualified and unqualified results. If unqualified, the current railway signal, power supply, communication, and SCADA interface needs to be rectified. After rectification, obtain the interface data of the current railway signal, power supply, communication, and SCADA interface after rectification and perform comparison until the detection result of the master control interface data is greater than or equal to the preset threshold. The preset threshold can be set according to the actual situation, and the application does not limit the value of the threshold. That is to say, the master control interface is the core component for whether its function can be realized. For non-master control interfaces, they will not affect the main function of the master control interface. The distinction between this master control interface and non-master control interfaces lies in ensuring the realization of the function of the master control interface without affecting the project progress. For non-master control interfaces, during the subsequent daily work arrangements, the staff need to handle them.
