From Metroflexx to the new Regioflexx

进一步报盘

从这次成功开始, we are now extending our suite of solutions for main line trains with Regioflexx – our solution for the next generation of suburban, 城际, regional, high-speed, 和 very-high-speed trains.

As you would expect from a modern integrated brake control system, Regioflexx具有服务制动功能, 紧急刹车, 和 wheel slide protection; communication with TCMS 和 propulsion; 和 diagnostic functions. Going well beyond these features, Regioflexx offers even more thanks to its specific architecture. 它是基于 两个独立的气动通道 allowing full per-axle control, 和 a dual independent electronic architecture, one SIL 2-based that performs the usual brake functions, 和 one SIL 4 that performs different redundancy 和 monitoring functions.

Rethinking Architecture to Boost Performance

Regioflexx’s unique 和 patented architecture offers numerous impressive benefits – especially in terms of 表演. 首先, its closed-loop regulation on actual cylinder pressure along with adaptive 和 self-tuning algorithms increase accuracy over time 和 make braking distances more predictable. This allows for greater accuracy in train stopping positioning. Dwell time is also improved thanks to high response times (<800 ms for brake application 和 release).

In addition to these significant benefits, the introduction of our new-generation DistanceMaster™ wheel slide protection (WSP) based on an adaptive filter, along with our deceleration compensation algorithm, take the use of actual wheel/rail adhesion to a new level. 一起使用, adaptive WSP 和 deceleration compensation improve braking 表演 by at least 50% compared to current WSP systems in st和ard degraded adhesion conditions. Deceleration compensation maximizes the use of available adhesion along the train in degraded adhesion conditions, 或在退化模式下(转向架隔离), 下坡, 等.). This makes trains much more resilient to adverse adhesion conditions 和 dramatically reduces maintenance costs (flat wheels).

解锁系统新功能

The patented architecture developed specifically for Regioflexx also opens up the field of possibilities in terms of system functionalities. 嵌入式动态WSP监控, 例如, provides efficient protection against the consequences of rapidly changing adhesion conditions. This avoids the intervention of the time-based watchdog function 和 significantly reduces the risk of axle lock. Regioflexx’s monitoring capabilities also enable the use of the available E/D Brake 和 the 紧急刹车 using propulsion technologies currently available. This allows for the optimization of sizing 和 reduces stress on the friction brake in the 紧急刹车. +, the Regioflexx braking system provides high-integrity speed information which enables the reduction of redundancies for speed-dependent functions, 比如开门控制.

简化为精简

Every effort has been made to simplify 和 streamline the architecture behind Regioflexx to make it easier to operate, 安装和集成. The system is natively designed to be network-operated, 例如. A train/vehicle data bus connection plus a safety loop are all that is needed to control the entire brake system. This allows for reductions in 火车集成 costs 和 improves overall system 可靠性.

To comply with interoperability TSI requirements, Regioflexx also features emulations of UIC distributor, multi-stage valve 和 average load valve, 在需要的时候. This reduces the number 和 complexity of additional pneumatic components along with associated installation 和 maintenance costs.

For very-high-speed trains (more than 250 km/h) the m和atory wheel rotation monitoring (WRM) system installation is complex 和 costly in traditional systems. 与Regioflexx, 另一方面, the WRM function is natively embedded, eliminating the burden of installing double WSP systems per car. The necessary electronic 和 pressure release redundancy is fully integrated into Regioflexx. This creates significant savings in terms of installation 和 maintenance costs.

Another distinctive feature of Regioflexx is its single integrated box (space 和 weight saving) that includes both electronics 和 pneumatics as well as several pneumatic valves replaced by software emulations. It offers cabling simplification through network operation, easy functional interfacing to traction 和 TCMS, 以及嵌入式WRM功能. 结果是, Regioflexx offers car builders 和 operators better cost competitiveness compared to traditional solutions.

Easy 维护 for Best-in-Class Train Availability

In addition to the multitude of advantages offered by Regioflexx’s state-of-the-art technology, the system has been designed for ease of maintenance to ensure maximum train availability. Thanks to the use of adaptive 和 self-tuning algorithms, Regioflexx offers extended MTBO (up to 15 years) 和 more stable 表演 over its lifetime. This means that only one overhaul will be required over a train’s 30-year lifespan. 它是 also natively equipped with predictive maintenance algorithms. It provides the usual diagnostic messages, but also residual time prior to overhaul 和 inspection flags based on abnormal consumption 和 drift identification.

The weight 和 size of Regioflexx allows a single operator to replace it on a train in less than 20 minutes. The design of Regioflexx 和 its bracket (installed on the vehicle) allows it to recognize its position on the train automatically, 和 therefore use the right brake setting for each position. Thanks to this feature, just one part is needed for the entire fleet. Regioflexx也很容易修改. With specialized test benches 和 a trained 和 certified workforce, maintenance can be performed at operators’ facilities.

维护 of a Full Brake-Control System has Never Been So Simple

Regioflexx maximizes train availability 和 is fault tolerant, making it a very cost-effective solution. A single failure affecting the service brake can be managed remotely (by the driver or TCMS), while keeping an 紧急刹车 per bogie available to ensure the train will never be stopped unnecessarily during operations.

Regioflexx Prepares for the Trains of the Future!

Regioflexx is set to become to solution of choice for forward-thinking train operators looking for the latest technology to help their trains speed into the future. Several operators around the world are already reaping the benefits of the system’s innovative features. 这些包括原生的 每轴 brake control 和 wheel slide protection. 这使全轴控制 没有额外费用. A single failure per Regioflexx will not affect more than 50% of local bogie emergency braking. This greatly contributes to the highest Guaranteed Emergency Brake Rate (GEBR).

Regioflexx also provides accurate 和 predictable 表演. It offers advanced adhesion management 和 closed-loop control on brake cylinder pressure. SIL 4 emulated functions contribute significantly to highly predictable braking 表演, 即使在退化的条件下, minimizing 表演 drift between dry 和 degraded adhesion conditions.

Regioflexx: a Certified Building Block for Your Train

全球最大网赌正规平台’s Regioflexx solution has received full safety certification from TÜV SÜD, including validation of safety levels associated with each function. In addition, DB Systemtechnik assessed Regioflexx’s compliance with the TSI st和ards. Regioflexx is also compliant with cybersecurity st和ards.
