[0002] In railway construction, interface management of the four electrical systems (electrical, electrical, and electronic systems) is particularly important. Railway construction is characterized by multi-unit participation, multi-professional coordination, multi-directional advancement, and cross-operation of multiple trades. The construction process involves numerous interface issues between various specialties. Due to factors such as construction models, process connections, structural safety, quality, and investment control, some electrical infrastructure is implemented by civil engineering units. Because of the significant differences in specialties and construction characteristics, low quality in the management of electrical interface projects has become a common problem and weakness in railway construction.

[0034] The feature representation data is compared with the features of the railway electrical interface data in the task to obtain the detection result;

[0035] The detection results are sent to the system module via the data transmission unit.

[0036] In some feasible embodiments, the step of sending the detection result to the system module via the data transmission unit includes:

[0037] The interface data is identified to obtain main control interface data and non-main control interface data;

[0038] 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;

[0039] Otherwise, the interface data of the current railway electrical interfaces after rectification is obtained and compared until the detection result of the main control interface data is greater than or equal to the preset threshold.

[0040] In some feasible methods, the step of obtaining the work task issued by the system module includes:

[0055] This application provides a railway electrical, electronic, and communication interface data management platform. The meanings of the railway electrical, electronic, and communication interfaces mentioned in this application are as follows:

[0056] The four electrical interfaces of a railway refer to the physical connections, functional coordination, or spatial connections between different equipment or structural components in the communication, signaling, power, and electric traction power supply systems. These interfaces are the core components ensuring the coordinated operation of the railway's four electrical systems.

[0057] Classification and specific examples of four electrical interfaces:

[0058] 1. Communication system interface: The physical connection point between communication equipment and supporting structure and transmission medium.

[0059] Example:

[0060] Antenna mounting interface: Flange connection between the base station antenna and the tower bracket.

[0061] Optical fiber splice interface: The optical fiber connection point inside the optical fiber splice box.

[0062] Equipment cabinet interface: Bolt fixing of the communication cabinet to the vibration-damping base of the equipment room. Clamp fixing of the leaky cable to the tunnel wall.

[0063] 2. Signal system interface: The connection point between signal equipment and trackside facilities and power supply circuits.

[0074] Electrical connection clamp interface: wedge-shaped crimping between the power supply clamp and the contact wire.

[0075] like Figure 1 As shown, in the first aspect, this application provides a railway electrical interface data management platform, including a standard management module, a system module, and an interface detection module.

[0076] The standard management module contains a database of railway electrical, electronic, and electronic interface data.

[0077] Specifically, railway electrical engineering encompasses communication, signaling, power supply, and electric traction power supply. The interface to be implemented in this application is not a line connection interface, but rather an interface connecting components within the railway electrical system. This interface includes standardized dimensional parameters, etc. For example, the connection point between a railway column and its base is an interface, representing two components.

[0078] During railway construction, all possible interfaces are recorded as interface data, and this interface data is then combined into a database for future use.

[0079] The system module, connected to the standard management module, is used to retrieve data from the database and form a work task, wherein the work task carries railway electrical interface data from the database.

[0080] Specifically, the system module includes a positioning unit and a task unit.

[0081] The positioning unit is used to locate the area where the work task is performed, forming a coordinate range. In other words, the unit can mark the coordinates of the area where the work task is to be performed, so that each worker knows their work area when performing the task. This can be understood as dividing the railway construction section map into several areas using the positioning unit; these areas refer to the areas where workers can complete their daily workload. For example, the railway construction section map is 100 meters long, and within these 100 meters are several railway electrical interfaces. Each worker can complete 10 meters per day, so each area is 10 meters.

[0082] The task unit, connected to the positioning unit and the standard management module, is used to retrieve data from the database to form work tasks, and to load coordinate ranges into the work tasks to form work tasks with coordinate ranges. Each work task includes multiple task points, each representing an interface of the railway's electrical, electronic, and communication systems. The task unit can retrieve corresponding standardized railway electrical, electronic, and communication interface data from the database based on the work task. In other words, the work task includes the work area and the standardized data for the railway electrical, electronic, and communication interfaces within that area. This allows workers to know their work area through the work task, and when inspecting a current railway electrical, electronic, or communication interface, they can compare the current interface data with the standardized data to determine the accuracy of the interface within the work area.

[0083] The interface detection module is connected to both the system module and the standard management module. It is used to detect the current railway electrical interfaces according to the work task, generate detection results, and feed them back to the system module.

[0084] Specifically, the interface detection module includes an interface detection unit, an interface comparison unit, and a data transmission unit.

[0085] The interface detection unit includes an industrial camera and a laser scanner, which are used to acquire interface data of the current railway electrical, electronic, and electronic control interfaces and transmit it to the interface comparison unit. The interface data includes 3D point cloud data of the interface contour and image data of surface texture and color. In other words, by capturing images with the industrial camera and scanning with the laser scanner, image data of surface texture and color, as well as 3D point cloud data of the interface contour, are obtained. The combination of these two different types of data reproduces the dimensions of the current railway electrical, electronic, and electronic control interfaces. It should be noted that the industrial camera and laser scanner can be integrated into smart electronic devices, such as mobile phones and tablets.

[0086] The interface comparison unit receives the interface data, compares it with the railway electrical, electronic, and communication interface data in the task, generates a detection result, and sends it to the data transmission unit. In other words, it compares the parameters of the current railway electrical, electronic, and communication interface reproduced by the interface data with the standardized railway electrical, electronic, and communication interface to generate a detection result. The comparison can be performed through feature comparison.

[0087] The data transmission unit is used to send the detection result to the system module. The data transmission unit can be a conventional wireless transmission module.

[0088] It should be noted that the interface comparison unit is also used to identify the interface data to obtain main control interface data and non-main control interface data. If the main control interface data is compared with the railway electrical interface data in the work task and the resulting detection result is qualified, the detection result is sent to the data transmission unit; otherwise, the interface detection unit is used to obtain the interface data of the rectified railway electrical interface and transmit it to the interface comparison unit. The interface comparison unit is also used to compare the main control interface data of the rectified railway electrical interface with the railway electrical interface data in the work task to form a detection result.

[0089] Specifically, the interface comparison unit identifies the interface data, resulting in main control interface data and non-main control interface data. Main control interface data represents interfaces that perform basic functions and do not affect project quality, while non-main control interface data represents interfaces that can be optimized for the main control interface to achieve better results. In other words, even without non-main control interfaces, the basic functions of the main control interface will not be affected.

[0090] 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 four-electrical interfaces are master control interface data and which are non-master control interface data. In this way, in the interface comparison unit, after identifying the interface data, it is only necessary to compare the master control interface data with the railway four-electrical interface data called in the work task in the database to obtain the detection result. If the detection result is greater than or equal to the preset threshold, it is determined that the detection result is 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 four-electrical interface needs to be rectified. After rectification, the interface data of the rectified railway four-electrical interface is obtained again through the interface detection unit and transmitted to the interface comparison unit for comparison until the detection result is qualified.

[0091] In one embodiment, the interface detection module further includes an adjustment unit.

[0092] Among them, the adjustment unit is connected to the interface comparison unit and is used to adjust the work task, form adjustment data, and send it to the interface comparison unit.

[0093] The interface detection unit will obtain the interface data of the current railway four-electrical interface and transmit it to the interface comparison unit.

[0094] The interface comparison unit compares the interface data of the current railway four-electrical interface with the adjustment data to form an adjustment detection result and sends the adjustment detection result to the data transmission unit.

[0095] 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, they can be adjusted on-site through the adjustment unit to form adjustment data and send it to the interface comparison unit. Next, the interface data of the current railway four-electrical interface is obtained through the interface detection unit and transmitted to the interface comparison unit for comparison. When the staff adjusts 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.

[0096] It should also be noted that since railway work is mostly outdoors in remote areas with poor signal, the database can be pre-loaded into the staff's handheld terminals, such as handheld all-in-one devices, but encryption is required. Next, the adjustment unit only needs to send the instruction data generated from the adjustment data to the system module at headquarters. Upon receiving the instruction data, the system module only needs to issue the corresponding instruction to the handheld terminal. Once the handheld terminal receives the instruction, it can decrypt the corresponding interface data in the database using the decryption information within the instruction. The decrypted interface data will then be used by the interface comparison unit.

[0097] Finally, it should be noted that blockchain technology is pre-loaded between the system modules and the handheld terminal. This ensures that every data adjustment leaves a trace, creating an unalterable timestamp and action, facilitating subsequent review and traceability. Blockchain technology is a conventional technology, and this application does not limit the specific type of blockchain technology used.

[0098] like Figure 2 As shown, in a second aspect, this application provides a method for inspecting a railway electrical interface data management platform, applied to the aforementioned railway electrical interface data management platform, the method comprising:

[0099] S100: Obtain the work tasks issued by the system module.

[0100] The task carries railway electrical interface data, which is retrieved from a database containing railway electrical interface data.

[0101] Specifically, step S100 may include the following steps:

[0102] S101, Obtain the railway construction section map and divide it into several areas according to the daily workload, wherein each area has a coordinate range.

[0103] Specifically, the railway construction section map is pre-built, and the daily workload represents the work that workers can complete each day. The historical daily workload completed by workers is obtained, and based on this, the railway construction section map is divided into several regions to ensure that each region represents a task that workers can complete in a single day. After dividing the region, the coordinates of each region are determined, allowing workers to know their work area for the day.

[0104] It should be noted that the division of railway construction sections may include the following steps:

[0105] Obtain the average number of regional interfaces processed by workers over historical N days, the maximum daily scanning distance of handheld terminals, and data obtained from the GIS system, such as terrain complexity factors like slope and obstacle density data obtained from the GIS system.

[0106] Weighted K-means clustering is used. The execution of the clustering algorithm follows a conventional method, and this application does not impose any limitations on it. The objective function Minimize is:

[0107] ;

[0108] in, , indicating the total number of regions. , indicating the first Number of interfaces per region This indicates the maximum daily scanning distance of the handheld terminal. , indicating the first A regional terrain complexity factor (dimensionless, value range [0,1]). , indicating the first Area of ​​each region and , representing the weighting coefficient (satisfying) By adjusting and The ratio can control the algorithm's focus on optimizing work efficiency. (Item) or balance of construction difficulty ( Item). For example: construction in mountainous areas (complex terrain): setting =0.7, =0.3; Plain construction (simple terrain): Set =0.3, =0.7.

[0109] The geofence coordinates are obtained through the objective function, and the division of the railway construction section map is dynamically adjusted based on the geofence coordinates.

[0110] S102, based on the aforementioned regions, retrieve railway electrical interface data from 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.

[0111] The work task includes multiple task points.

[0112] Specifically, after the work task is determined, the railway electrical interface data from the database is retrieved according to the task to form the work task. In addition, coordinates are assigned to each task point, so that workers can record the coordinates while completing the task, avoiding the problem of inconsistent task point locations. It should be noted that railway construction sections may be in areas with poor signal, such as tunnels and valleys. Therefore, the database can be pre-loaded into the handheld terminal and encrypted. This allows for direct access to the database from the handheld terminal even in areas with poor signal. Decryption of the database can be achieved through facial recognition or by issuing decryption commands from the system module. Once the database is decrypted, the railway electrical interface data can be retrieved from the database.

[0113] It should be noted that offline data security mechanisms for databases can be implemented through the following methods:

[0114] Data encryption uses the national standard SM4 algorithm to encrypt offline packets, and the key is generated by the system module using quantum random numbers.

[0115] Device binding involves writing the device fingerprint (CPU serial number + base station ID) hash value into the encrypted packet header;

[0116] Decryption conditions:

[0117] Geofencing verification: GPS coordinates must be within a specified range of meters in the task area, such as within 500 meters;

[0118] Time window limitation: The decryption validity period is the specified time of the task, such as 24 hours after issuance;

[0119] Biometric verification: Requires certification through liveness detection factors.

[0120] S200, according to the work task, the current railway electrical interfaces are tested and the test results are obtained.

[0121] Furthermore, step S200 may also include the following steps:

[0122] S201, obtain the interface data of the current railway electrical interfaces.

[0123] The interface data includes 3D point cloud data of the interface outline and image data of surface texture and color.

[0124] Specifically, the acquisition of interface data can be done using the equipment used in the aforementioned railway electrical interface data management platform, which will not be elaborated here.

[0125] It should be noted that the acquired 3D point cloud data and surface texture and color image data are synchronized in time. For example, PTP (Precise Time Protocol) is used to achieve microsecond-level synchronization between the scanner and the camera, ensuring spatial alignment between the point cloud and the image. This ensures that the resulting 3D model has corresponding surface texture and color.

[0126] S202, using the three-dimensional point cloud data, obtain the three-dimensional model of the current railway electrical interface.

[0127] For 3D point cloud data, conventional methods can be used to construct 3D models. For example, the Poisson reconstruction algorithm can be used to reconstruct the depth (Octree Depth) = 10 (corresponding to a voxel resolution of 0.001m), the sample spacing = 0.002m, the surface smoothness = 0.8, and the hole repair threshold = 0.05m² (holes with an area smaller than this value are automatically filled).

[0128] S203, using image data of surface texture and color, obtain the surface features of the current railway four-electric interface.

[0129] For image data of surface texture and color, conventional feature processing methods can be used. For example, Local Binary Pattern (LBP) can be used to analyze surface texture consistency and identify the analysis area. A uniform local binary pattern is adopted with a neighborhood radius R=3 pixels, a number of sampling points P=8, and a feature histogram bin number of 59 (corresponding to the uniform pattern type). Rotation invariance processing: calculate the minimum rotation equivalent representation for each LBP feature value.

[0130] S204. Based on the three-dimensional model and surface features of the current railway four-electric interface, obtain the feature representation data of the current railway four-electric interface.

[0131] Based on the 3D model and surface features, a weighted stitching method (geometric features of the 3D model weighted at 0.6, surface features weighted at 0.4) is used for feature fusion to obtain the feature representation data of the current railway electrical interface. Next, the feature representation data of the current railway electrical interface is normalized for comparison with standardized railway electrical interface data in subsequent steps.

[0132] S205, compare the feature representation data with the features of the railway electrical interface data in the work task to obtain the detection result.

[0133] The normalized feature representation data of the current railway four-electric interface is compared with the feature of the railway four-electric interface data in the work task to obtain the detection result. The feature comparison can use conventional feature comparison methods, and this application does not limit it.

[0134] It should be noted that due to various reasons such as comparison, there may be differences between the detection results and the actual results. For example, during the detection process, when comparing the feature representation data of the current railway electrical interface with the feature data of the railway electrical interface in the work task, three differences were found. That is to say, in the case of differences, the following steps are also included:

[0135] Construct a selection box;

[0136] Obtain the edges of the feature differences, and based on the edges of the feature differences, obtain the edge coordinates of the feature differences;

[0137] Based on the edge coordinates of the feature differences, a bounding box is constructed, where the bounding box can be a circle, rectangle, or similar shape. The bounding box can select the feature differences.

[0138] The rule boxes are presented on the three-dimensional model of the current railway electrical interface to obtain a three-dimensional model with rule boxes.

[0139] In this way, staff can observe the differences in features based on photographs generated from the 3D model or directly on the 3D model. This not only facilitates timely understanding by staff but also allows for on-site handling of minor issues with the railway's electrical, electronic, and communication interfaces, ensuring that the interfaces meet requirements. The presentation can be done via a display, such as the monitor on a scanner.

[0140] The feature difference here refers to the location of the current railway electrical interface features. Because the features of the current railway electrical interface differ from the features of the railway electrical interface data in the work task, the location of the current railway electrical interface features is marked with edges to form the edge of the feature difference.

[0141] It should be noted that the selection box is built as a layer on the 3D model, so it will not affect the 3D model.

[0142] In addition, the annotation boxes use a color-coded hierarchical mechanism: red boxes indicate primary control items affecting structural safety (such as grounding terminal misalignment), yellow boxes indicate secondary control items affecting function (such as misaligned sealing rings), and blue boxes indicate appearance-related issues (such as coating scratches). This layered visualization process ensures the integrity of the original test data while providing intuitive location of differences.

[0143] After the annotation box is generated, a 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 handling plan (e.g., "re-drilling and tapping required"), the second line is the impact level (e.g., "Level A: Affects lightning protection grounding"), and the third line is the urgency level (e.g., "to be handled within 24 hours"). The data in the engineering knowledge base can be derived from historical maintenance cases. For example, for common problems such as bolt hole position deviation, the system will prioritize recommending standardized repair solutions such as hole enlargement and bushing.

[0144] It should be noted that the indexing of the engineering knowledge base can be a coded index, with each code having a unique ID. This code is loaded into the features of the railway electrical interface data in the work task. This allows the features of the railway electrical interface data in the work task to be located using the current features of the railway electrical interface. Based on the coded index corresponding to the features of the railway electrical interface data in the work task, the standardized repair solution for this problem is found in the engineering knowledge base and displayed in the first line of the handling plan. Furthermore, the impact level of the second line and the urgency level of the third line can also be mapped to the standardized repair solution. That is, after determining the standardized repair solution, the corresponding impact level of the second line and the urgency level of the third line can be obtained and displayed together on the layer.

[0145] S206, the detection results are sent to the system module via the data transmission unit.

[0146] When transmitting data through the data transmission unit, the transmission protocol used is a conventional protocol, and this application does not limit the protocol.

[0147] Specifically, S206, the step of sending the detection result to the system module through the data transmission unit may include the following steps:

[0148] S2061, The interface data is identified to obtain main control interface data and non-main control interface data.

[0149] Specifically, the method for identifying interface data involves preloading a suitable convolutional neural network (CNN) model into the interface comparison unit. This CNN model is a pre-trained model, such as a ResNet-18 model. The 3D model formed from the interface data is converted into an image, such as an orthographic projection image. This image is then used as input to the CNN model for recognition, thereby obtaining the main control interface data and non-main control interface data.

[0150] 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;

[0151] Otherwise, the interface data of the current railway electrical interfaces after rectification will be obtained and compared until the main control interface data is greater than or equal to the preset threshold.

[0152] It should be noted that the definition of the main control interface is as follows: core components involving structural safety (such as grounding terminals and load-bearing supports) can be determined according to the relevant standards of railway electrical engineering.

[0153] After determining the main control interface data, the detection result of the main control interface data is compared with a preset threshold to obtain a qualified or unqualified result. If it is unqualified, the current railway electrical interface needs to be rectified. After rectification, the interface data of the rectified railway electrical interface is obtained and compared again until the detection result of the main control interface data is greater than or equal to the preset threshold. The preset threshold can be set according to the actual situation, and this application does not limit the value of the threshold. That is to say, the main control interface is the core component that determines whether its function can be realized, while non-main control interfaces do not affect the main function of the main control interface. The distinction between main control interfaces and non-main control interfaces is that the function of the main control interface is guaranteed without affecting the project progress, while non-main control interfaces need to be handled by staff in subsequent daily work arrangements.

[0154] S300, the detection results are fed back to the system module.

[0155] The test results are submitted wirelessly and transmitted to the system module for recording and use.

[0156] In one embodiment, the step of obtaining the work task issued by the system module includes:

[0157] Obtain the adjustment data for the work task;

[0158] The adjusted data is loaded into the work task to obtain the adjusted work task;

[0159] The interface data of the current railway electrical interfaces are compared with the adjustment data in the adjusted work task to form an adjustment detection result, and the adjustment detection result is sent to the data transmission unit.

[0160] Specifically, the data adjustment can be found in the description of a railway electrical interface data management platform, which will not be repeated here.
