Description

Technical Field

[0001] The present invention relates to the technical field of on-board equipment of a motor vehicle group, and more particularly to a card control system and an operation method for wheel diameter modification and software upgrade of on-board equipment. Background Art

[0002] At present, the ATP onboard equipment of EMUs is a key technical equipment to ensure driving safety and improve transportation efficiency. In recent years, with the continuous increase in the number of EMUs, driving safety is facing challenges. It is an important part of improving the safety level of railway operation to discover and eliminate unsafe factors that affect driving in advance through scientific and technological means. Wheel diameter modification and software upgrade are two tasks in ATP maintenance with high frequency, high difficulty, high personnel participation and low automation level. Improving the accuracy and automation level of the above two tasks has become an important task at present. The wheel diameter modification operation is often connected after the wheel rotation operation of the EMU depot. At present, the daily wheel diameter modification operation relies on manual extraction of wheel diameter modification parameters and generation of wheel diameter modification operation orders through the wheel diameter modification sheet provided by the EMU depot. According to the operation sheet, relevant operators are arranged to work on the train, and the computer screenshots of the process before and after the wheel diameter modification are saved. Finally, this information is submitted to the management personnel for review and confirmation. The software upgrade operation process is similar to the wheel diameter modification. First, the software upgrade telegram is obtained, and the board to be upgraded and the corresponding software version are determined according to the telegram, and a software upgrade plan is formulated. According to the software upgrade plan, the first operating EMU is determined, and relevant operating personnel are arranged to operate on board. After the operation is completed, a screenshot of the upgraded software version is taken and submitted to the analysis work area to confirm and review the software upgrade results.

[0003] The above-mentioned wheel diameter modification and software upgrade process has the following problems: ① The preparation of wheel diameter modification and software upgrade work orders cannot be automatically combined with the daily maintenance plan, and overly relies on manual experience and multiple confirmations, which is time-consuming and labor-intensive; ② There is a lack of effective and convenient technical means to monitor the operation process comprehensively and efficiently; ③ The approval of the task order and the confirmation after modification also lack systematic supervision, resulting in untimely confirmation of the task order and post-operation, and difficulty in tracing the operation process; ④ After the operation is completed, it is impossible to automatically confirm whether the EMU operated is correct, and it is impossible to compare whether the pictures generated during the operation are consistent with the operation plan.

[0004] To solve the above problems, this project will use intelligent information extraction OCR (Optical Character Recognition), workflow engine, image recognition, natural language processing and other technical means to design an operation card control system for wheel diameter modification and software upgrade of on-board equipment based on intelligent information extraction.

[0036] Figure 2 A schematic diagram of the wheel diameter modification notification information extraction task provided by the present invention. DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The embodiment of the present invention discloses a card control system for modifying wheel diameter and upgrading software of vehicle-mounted equipment, such as Figure 1 As shown, it includes: a parameter collection terminal, an AI algorithm server, an application server, a switch, a database server and a mobile operation terminal; the parameter collection terminal, the AI ​​algorithm server, the application server, the database server and the mobile operation terminal are respectively connected to the switch;

[0039] (1) Wheel diameter modification / software upgrade parameter collection terminal: This terminal is mainly composed of a customized high-speed scanner and a personal computer. The customized high-speed scanner is used to quickly outline and focus the size and position of the wheel diameter modification sheet in the wheel diameter modification operation, so as to generate accurate and clear pictures; for the upload of documents such as telegrams and software upgrade plans in the software upgrade operation, the system uses information extraction technology based on natural language processing to generate key upgrade information including the upgrade vehicle range, upgrade equipment board, and version information before and after the upgrade. This provides support for the next step of information extraction.

[0040] (2) AI algorithm server: mainly uses multimodal OCR technology to accurately extract and structure the information in the wheel diameter modification notification form; uses multimodal OCR technology and natural language processing technology to extract and structure the information in the software upgrade telegram, and provides the recognition results to the application server.

[0041] (3) Application server: mainly responsible for implementing business processes, providing support services for front-end display, and is the scheduler of this system. Its main functions are:

[0042] 1) Responsible for scheduling the data provided by the underlying layer.

[0043] 2) Present the interface to the user according to business rules.

[0044] 3) Communicate data with the AMIS server to obtain daily maintenance plans and schedule shifts.

[0045] 4) After the operation is completed, the results of wheel diameter modification and software upgrade are uploaded to form a closed loop.

[0046] (4) Database server: mainly responsible for storing system data, including structured data and unstructured data such as pictures and videos.

[0047] (5) Mobile operation terminal: mainly responsible for data collection during on-site operation. The task is stored locally in an offline manner, and then the operation is carried out on the vehicle. The requirements in the instruction book are implemented one by one in a streamlined manner. The entire on-site operation process is divided into several processes, such as sign-in, vehicle number and terminal number verification, wheel diameter modification / software upgrade operation, and testing. The authenticity of the operation is ensured by means of on-site real-name sign-in and vehicle number and terminal number recognition, so as to avoid situations where operators go to the wrong vehicle or the wrong terminal.

[0048] Data servers, switches, and user terminals are connected through the railway office network, and the network access points of each device are equipped with firewalls.

[0049] The present invention further includes the following specific scheme:

[0050] Wheel diameter parameter multimodal OCR technology, wheel diameter modification notice information extraction task is divided into two subtasks for research:

[0051] (1) Semantic entity recognition. Each detected text is classified into, for example, wheel diameter value, vehicle group number, vehicle number, axle number, notification date, etc. The wheel diameter modification notification information extraction task is shown in Figure 2 , Figure 2 The yellow, green, red, blue and brown boxes in the figure represent the vehicle number, wheel diameter value, axle number, vehicle assembly number and notification date entities respectively.

[0052] (2) Relationship extraction: classify the relationships between detected entities and find the corresponding relationships between entities. Figure 2 The blue connecting line represents the "belonging" relationship, indicating the 1st, 2nd, 3rd, and 4th axles of the vehicle. The orange connecting line represents the "belonging" relationship between the wheel diameter value and the axle.

[0053] Wheel diameter parameter image annotation technology

[0054] The extraction of wheel diameter parameters is the source of the entire operation, and the data must be 100% correct. In order to intuitively feedback to the user the recognition of each wheel diameter parameter, the system will write the recognition results back to the collected pictures, and mark the pictures with different colors according to the recognition accuracy. Green means the recognition rate is above 99%, yellow means the recognition rate is between 95% and 99%, and red means the recognition rate is below 95%. Through the above processing, first, let the user know clearly which values ​​​​are extracted from the wheel diameter parameters, second, let the user know what the extracted values ​​are, which is convenient for the user to check and verify; third, let the user know which parameters should be paid more attention to, thereby improving the user's work efficiency and confirmation accuracy.

[0055] Wheel diameter parameter intelligent verification technology

[0056] The accuracy of multimodal OCR technology recognition is very high, but the wheel diameter modification operation is not allowed to make any mistakes. The extraction of wheel diameter parameters must be 100% accurate. For this reason, it is not enough to rely solely on multimodal OCR technology and image marking technology. On this basis, it is necessary to introduce standard requirements to verify the identified wheel diameter parameters in multiple dimensions and angles. For example, compare the wheel diameter value recognized this time with the wheel diameter value after the last modification. If it is found that the wheel diameter value this time is larger than the last wheel diameter value, the user is prompted whether the wheel has been changed. Otherwise, it is necessary to confirm whether the "Wheel Diameter Change Notice" provided is correct; in addition, the system also verifies the wheel diameter difference within the same bogie and the wheel diameter difference of the same wheelset, and confirms the extracted wheel diameter value from multiple dimensions to ensure that the wheel diameter value extracted by the system is accurate and reduce manual participation.

[0057] Software upgrade event extraction technology

[0058] The research on event extraction tasks aims to automatically extract event information of interest to users from unstructured natural language texts and represent them in a structured form. The development of this task is driven by application needs. Event extraction methods based on deep learning can be mainly divided into two categories: supervised learning and remote supervised learning. Supervised learning methods use manually annotated data sets during training. Through these annotated data, the model learns the rules and patterns of event extraction, so that it can accurately extract event information in new texts. Remote supervised learning methods automatically annotate corpora by aligning remote knowledge bases to obtain labeled corpus data. This method overcomes the dependence on manually annotated data sets, and can also use large-scale remote knowledge bases for corpus annotation, thereby increasing the scale and diversity of data. Whether it is supervised learning or remote supervised learning methods, they have played an important role in event extraction research and provided an effective means for realizing automated event information extraction.

[0059] Software upgrade task automatic scheduling technology

[0060] After completing the preliminary preparations for the software upgrade task, the key information of the software upgrade will also be extracted by event extraction technology and converted into structured data that can be processed by computers. Based on the above software upgrade structured data and the vehicle information and vehicle storage information provided by the AMIS system, flexible work scheduling can be carried out according to the needs of on-site operators. This module has the following functions:

[0061] (1) Based on the vehicle entry plan, the system automatically generates vehicle information available for software upgrade every day to help on-site operators determine the day's software upgrade schedule.

[0062] (2) If the train undergoing software upgrade is the first train, remind on-site operators to conduct static tests and add passengers.

[0063] (3) According to the scope of the software upgrade task, record the vehicles that have completed the software upgrade and the vehicles that have not completed the software upgrade, and remind the on-site operators to perform software upgrade operations on the vehicles that have entered the warehouse on the same day and have not completed the software upgrade.

[0064] Software upgrade key work node card control technology

[0065] When performing software upgrades, whether the work is done on the correct vehicle and whether the upgraded version of the software is correct and complete are key work nodes of the software upgrade task. These nodes are related to whether the software upgrade is completed correctly, and the automated card control of these nodes is the pain point of the current on-site work area. During on-site operations, these key nodes all need to take photos or screenshots of key information such as the software version. This system uses the above-mentioned OCR technology and image annotation technology to identify and extract the information contained in the photos or screenshots of key nodes, and compares the above information with the tasks extracted from the software upgrade plan document in advance to ensure that the software upgrade is carried out as planned.

[0066] Workflow Technology

[0067] The whole process of wheel diameter modification and software upgrade is divided into multiple stages, including plan preparation, plan review, plan issuance, on-site operation, operation result confirmation, operation record registration and other steps. If there is no unified process to string these processes together, it is easy to put the wrong things in the wrong place, the operation records are easy to be confused, and the approval and confirmation process is cumbersome. Based on the above problems, the workflow is used to connect the entire operation process from the source. The source data can be seen during approval, and the approval personnel can quickly approve it; when confirming the results, the operation results can be compared with the original wheel diameter change notification form and the software upgrade telegram file on the same screen, and the confirming personnel can confirm accurately and quickly. The whole process can be tracked and traced, which greatly facilitates system users and improves work efficiency.

[0068] Through these technical means, the present invention can intelligently monitor and control wheel diameter modification and software upgrade operations, reduce the impact of human factors, and improve the standardization and accuracy of operations. At the same time, it can also improve operating efficiency, prevent problems such as running the wrong vehicle, taking wrong parameters, and operating errors, thereby improving in-depot operating efficiency and reducing working hours.

[0071] When the operation plan and software upgrade plan are generated, the system uses the workflow engine to start the circulation from the plan. First, the approval of the plan is completed according to the pre-set workflow. When the on-site operation is completed, the mobile operation terminal uploads the operation process pictures to the system. The system will trigger the result review process again and push the result records, the original wheel diameter change notification form, and the software upgrade telegram file to the reviewer.

[0072] When the operation results are confirmed, the system will automatically generate operation records.
