In recent years, the high-speed railways that had been put into operation in the early stage in China have gradually entered the overhaul and renovation cycle. With the gradual increase of renovation projects, the demands for dynamic detection and verification of signaling systems after infrastructure renovation also increase simultaneously. However, there is still a lack of dynamic detection technical solutions and standards for renovation projects in our country. This paper studies the signaling equipment upgrading in the renovation projects, and divides the renovation projects into three categories. According to the characteristics and detection requirements of different types of projects, the dynamic detection items, case selection principles, sequence compilation principles, dynamic detection methods, and judgment of dynamic detection results of signaling systems are proposed. It can provide technical support for unifying the dynamic detection methods and standards of the high-speed railway signaling system after infrastructure renovation.

In the Guangzhou-Shenzhen-Hong Kong Express Rail Link project, an advance starting signal SZ is specially installed at the forward departure exit in down direction throat area of West Kowloon Station (WKT) in order to meet the demands of only one train running in the ventilation area and a 3-minutes interval between trains. Since the throat area of this station is relatively short, the setting of the signal has impacts on the interlocking logic of the arriving and departure route as well as the shunting route of this departure exit. In this paper, an in-depth analysis of these effects is carried out, and the problems of route segmentation and switchless shunting route are solved by controlling the nature of segmented route, adding special interlocking relation checks, adjusting the timing of shunting signal at stop and section unlocking mode, etc. The use of the scheme not only meets the operational requirements, but also ensures safety and efficiency.

DMI is the man-machine interface device for drivers to operate the high-speed train control system. At present, two DMIs are installed at each end of a high-speed train. Because the two DMIs are cold standby, seamless automatic switchover is not supported in case of failure. Therefore, the failure of DMI will inevitably lead to brake and stop of the train and reduce the operation efficiency of the train. In this paper, the DMI hot standby scheme of high-speed train is given, and the key technologies of DMI hot standby are elaborated in detail, including switching strategy, hot standby principle of window operation and hot standby principle of text confirmation. The DMI hot-standby scheme has been used to develop DMI hot-standby function and realize dual DMI hot standby switchover. It has been applied and tested in engineering, which can improve the availability of the system and guarantee the efficiency of railway transportation.

The computer based interlocking technical specifications require that the interlocking equipment shall not arrange routes not listed in the interlocking table. This paper studies a conflicting signal determination algorithm that is based on the recommended route and can be implemented in the project. The algorithm determines conflicting signals by comparing the routes that needs to be judged with the recommended routes that meets the requirements. Then the decision algorithm is integrated into the interlocking table auxiliary compilation software through C++ programming language and MFC framework class. Using this software can significantly reduce the workload of designers and avoid the inconsistency between conflicting signals and actual recommended routes.

In this paper, a liaison circuit for crossover turnout between yards of a station with two yards is designed based on fail-safe principle and meeting the technical requirements for liaison circuit between yards in General Principles for Combined Circuit of Centralized Interlocking (TB/T 2307-2017). The crossover turnout between yards is double acting and centrally controlled by one of the two yards. The crossover insulation joint of the crossover turnout is taken as the operation interface between the two yards, and the overline route is divided into two sections by setting up a virtual signal at the crossover insulation joint. On the premise of ensuring the safety of train operation, the design of liaison circuit for crossover turnout is simplified, which plays a certain reference role for the same type of engineering design.

The new superstructure structure design makes the railway building structure below it different from the conventional EMU depot, which brings certain troubles to the wireless network design. Therefore, it is necessary to study the wireless coverage in this special environment, so as to facilitate future wireless network planning in similar scenarios. Combined with the Hangzhou west EMU depot project, this paper compares the influence of omnidirectional antenna and directional antenna on wireless coverage and discusses the design rules of the wireless system in such a railway environment. Finally, it is determined that the scheme of using the directional antenna for wireless network coverage in this kind of scenario is better.

The radio block center (RBC) system is the core ground subsystem of the high-speed railway train control system. The centralized traffic control (CTC) system is an important part of the high-speed railway train control system. The communication information between CTC and RBC satisfies RSSP-II protocol required, RBC sends train information to CTC, and CTC sends command information to RBC. Based on the actual application of train control system, this paper mainly introduces the communication mechanism of the interface between CTC and RBC, then analyzes the communication information between CTC and RBC in the new train control system, and gives some suggestions on how to apply RBC information to CTC.

When the signal display mode is off, both CBTC and non-CBTC trains can run on the track. For CBTC trains, drivers operate trains according to on-board signals and do not need to pay attention to trackside signals. However, for non-CBTC trains, drivers must operate trains according to the trackside signals. Based on the analysis of different operation scenarios, this paper gives the determination process of signal lighting section, so as to ensure that the trackside signal can be lighted in time when the non-CBTC train approaches the signal in front, so as to ensure the safety of train operation.

The red light strip fault of axle counter for signaling system of Hangzhou Metro Line 1 Phase 3 occurred during the early commissioning and operation period of EMU. The headplate of the axle counter is monitored by oscilloscope and the cause of the fault is determined to be external interference. This paper introduces the working principle of axle counter, analyzes the cause of the fault, and introduces the corresponding measures in detail. The test and actual operation performance prove that the fault rate of red light strip can be effectively reduced by adding the double shielding line of traction inverter and brake resistance and adding the current equalizer beside the track, which can be used as a reference scheme for similar fault treatment of other lines.

Taking the choke transformer as the research background, this paper puts forward a new idea of the magnetization test circuit of the choke transformer based on the deep understanding of the field application of choke transformer and combined with the ability of existing test instruments and equipment. Through circuit design, the test scheme of choke transformer is as close as possible to the real state of use, and the magnetization test of a single choke transformer is realized without using signal coil to aid the test, which makes the magnetization test of the choke transformer more real and effective. In order to verify its feasibility, a test environment is set up and the magnetization test circuit of the choke transformer is verified.

During the commissioning of the on-site computer interlocking equipment, the action of moving and clicking of serial mouse occasionally occurs in the control & display computer when no one is operating, and results in effective but wrong operation on the interlocking software. It is suspected to be related to the IKVM-1000 long line driver. In order to ensure the normal commissioning and use of the interlocking equipment, a series of tests on the IKVM-1000 optical fiber interface, serial port and serial mouse is carried out, and the fault phenomena and causes are analyzed, so as to solve the problem of misoperation of control & display mouse.
