There is a need to upgrade the maintenance measures associated with balise equipment, by improving the management method of balise telegrams dominated by manual operation, to continuously enhance management efficiency. To this end, this paper studies the management of balise telegrams. It briefly describes the main functions and roles of the balise telegram management system. Then, it analyzes the overall requirements for the balise telegram management system, proposes an overall design scheme, and elaborates on the network structure design and functional module partition of the balise telegram management system. Moreover, it describes such issues as the relevant technologies and specific data structures, module functions and operation interfaces to implement the software. Thanks to the intelligent management system of balise telegram based on real-time parameterized data, a whole-process safety management system of balise telegram has been established, with the railway bureau performing the integrated management, and the signaling personnel at all levels performing the dynamic management of the balise telegrams under the "cloud-edge" collaboration framework, to provide reliable guarantee for the safe train operation of high-speed railways.

This paper analyzes the characteristics of acquisition of functions in the technical conditions of the centralized signal monitoring system and verifies the analysis results through on-site trial in specific projects. In this way, it seeks to find installation methods to greatly improve the product quality of the centralized signal monitoring system. Decentralized installation means installation nearby monitoring objects, this installation method will shorten the monitoring and acquisition wirings and reduce the safety risks. Preinstallation at the factory will advance the field wiring to the assembly and prefabrication stage, which improves accuracy and achieves standardization. The installation method combining these two has been proved to be an effective approach.

Based on an analysis of the existing test scenarios of the onboard system, this paper proposes an implementation scheme of the vehicle interface simulation system. The scheme divides the vehicle interface simulation system into three layers, i.e. information management layer, operation logic layer, and interface execution layer. The functions of each layer feature high cohesion and low coupling, which improves the adaptability of the test system and reduces the costs of building the test environment. This paper also elaborates on the structure and implementation of the vehicle interface simulation system from three aspects, i.e. system architecture, system composition and service process. Thus, it provides a new solution for establishing a general-purpose vehicle simulation test environment.

In the network planning and design of marshaling yards, it is necessary to not only ensure network reliability, but also consider the utilization rate of link bandwidth, so as to achieve both redundancy switching and load sharing. Single gateway deployment, Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP) can no longer meet the network requirements of marshaling yards. Building on the construction and implementation situation of Computer Integrated Process System (CIPS) in Baoji East Station, this paper proposes a double-protocol interaction method based on MSTP+VRRP technology to achieve redundancy switching and load sharing, and ensure high network reliability and full utilization of network resources in marshaling yards.

As the internationalization of the software market is accelerating, the translation of dynamic data is increasingly important. In the general-purpose translation framework of dynamic data designed in this paper, the following methods are adopted. The aspect-oriented technology AOP is used to weave the translation function. The customized annotations are used to mark the methods and fields with translation requirements. The translation contents and unique key values are used to meet the uniqueness requirement of interactive data. The two-way translation function is used to ensure the decoupling between translation and services. The proposed translation framework has been implemented and applied to railway information system projects in the overseas market. It not only meets the needs of multilingual translation, but also greatly improves the development efficient thanks to its portability and high reusability.

With the continuous development of subway networks in various cities and the application of new technologies in subways, passengers have increasingly high requirements for subway services. There is an urgent need to explore how subways can quickly and effectively provide quality services for passengers. Taking Nanjing Subway as an example, this paper first analyzes the behavior of passengers by using relevant travel data, to introduce the concept of smart customer service system, and then describes the design concept of smart customer service system. Through the transformation at three layers, i.e. system layer, application layer and management layer, the station is gradually changed to the "unmanned" operation mode, so that a "one-stop" convenient smart customer service system is created. In this way, the station operation staff and operation cost are reduced.

As the urban rail transit signaling systems of some subway lines have been in service for nearly 15 years, there is an urgent need to retrofit such signaling systems. The traditional retrofitting solution has such problems as huge construction difficulties, long construction period, large amount of involved equipment. Thanks to technical development, it is possible to reduce the retrofitting costs of signaling systems. The paper provides a phased retrofitting solution, which can not only reduce the costs and increase the efficiency, but also eliminate as soon as the negative impacts of the failure rate of existing onboard equipment on subway operation.

Track circuit is an important device to reflect the train occupancy status and transmit the train control information. During the retrofitting of the normal-speed railways, there has been the problem of mismatch between track circuits due to the high running speed of the single-locomotive train, the delay in equipment response, and the delay in relay action. This paper proposes the method of slow-operating circuit using capacitors and resistors or equipment replacement to solve this mismatch problem. The proposed method has been applied during the retrofitting of the track circuits of Rongjiawan Station of Beijing-Guangzhou Railway, and has been proven to effectively solve the problem of mismatch between track circuits and such ensuing problems of the interlocking system as fail to unlock normally, forget to unlock, and report track unoccupied in the presence of train.
