The edge-cloud collaboration scheme is proved efficient to reduce the latency. However, the data characteristics and communication demand of the tasks in the railway environment monitoring system are all different and changeable, and the latency contribution of each task to the system is discrepant. Hence, two valid latency minimization strategies based on the edge-cloud collaboration scheme is developed in this paper. First, the processing resources are allocated to the tasks based on the priorities, and the tasks are processed parallelly with the allocated resources to minimize the system valid latency. Furthermore, considering the differences in the data volume of the tasks, which will induce the waste of the resources for the tasks finished in advance. Thus, the tasks with similar priorities are graded into the same group, and the serial and parallel processing strategies are performed intra-group and inter-group simultaneously. Compared with the other four strategies in four railway monitoring scenarios, the proposed strategies proved latency efficiency to the high-priority tasks, and the system valid latency is reduced synchronously. The performance of the railway environment monitoring system in security and efficiency will be promoted greatly with the proposed scheme and strategies.</p></div>","PeriodicalId":100607,"journal":{"name":"High-speed Railway","volume":"1 3","pages":"Pages 185-194"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949867823000363/pdfft?md5=0ec6a48b35b6c531cb645df9e6226a6b&pid=1-s2.0-S2949867823000363-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91668671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A virtual sample generation solution based on Generative Adversarial Network (GAN) is proposed to overcome this shortcoming. Aiming at augmenting the sample classes with the imbalanced data problem, the GAN-based virtual sample generation strategy is embedded into the establishment of fault prediction models. Under the PHM framework of the on-board train control system, the virtual sample generation principle and the detailed procedures are presented. With the enhanced class-balancing mechanism and the designed sample augmentation logic, the PHM scheme of the on-board train control equipment has powerful data condition adaptability and can effectively predict the fault probability and life cycle status. Practical data from a specific type of on-board train control system is employed for the validation of the presented solution. The comparative results indicate that GAN-based sample augmentation is capable of achieving a desirable sample balancing level and enhancing the performance of correspondingly derived fault prediction models for the Condition-based Maintenance (CBM) operations.</p></div>","PeriodicalId":100607,"journal":{"name":"High-speed Railway","volume":"1 3","pages":"Pages 153-161"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949867823000338/pdfft?md5=6eeea0547e12285cda1b991909520ac0&pid=1-s2.0-S2949867823000338-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85306302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to assist dispatchers in rescheduling trains, this paper introduces an innovative Human-Computer Interaction framework. This framework enables train dispatchers to propose different timetable adjustment instructions to the original or adjusted timetable. These instructions will be processed, stored, analyzed, and digested by computer program, which finally lead to the modification and calculation of the embedded mathematical model, then a new adjusted timetable will be produced and provided to dispatchers for checking and modifying. This framework can iterate for unlimited times based on dispatchers’ intentions, until the final results satisfy them.
