Swiss Air-Ambluance Rega has introduced a complete new mission control system and thereby developed a new telecommunication infrastructure system with SCS AG as its partner. The system is Voice-over-IP (VoIP) based and features a custom-designed user frontend that perfectly fits the mission controller’s needs and includes two VoIP-telephones per workplace. The system also integrates communication through the Rega-proprietary Switzerland-wide radio system which was also developed mainly by Supercomputing Systems AG.

The communication system is seamlessly integrated to a mission control system delivered by Hexagon and ideally supports the operative processes of Rega mission controllers. In addition to the introduction of these new software solutions the entire mission control IT infrastructure of Rega has moved to external data centers. The telecommunication core systems run redundantly in two geographically separated locations. This ensures a high availability.

The development of the communication system including testing, deployment and go-live took SCS one year.

Industrial applications require an increasing degree of trust and privacy protection. Proof of existence, of origination or of a consistent track record gain importance. Trusting the timestamps and the integrity of sensor data can be a crucial requirement, i.e. for using surveillance camera footage as evidence in court.

SCS has set up an infrastructure that proves a concept to add trusted timestamps to sensor data based on a public blockchain. This allows to prove that (sensor) data has been captured at a specific point in time. Such a proof includes existence at certain time as well as prior inexistence, with a time precision of minutes. While it has previously been possible to prove that data existed before a certain point in time, this concept show a way to also prove that data only existed after
a certain point in time.

The safety and availability of SBB railway infrastructures is ensured by the Infrastructure Monitoring business unit. SBB requires a “towed diagnostics vehicle” (gDFZ) to fulfill this duty and at the same time to provide an enhancement to the existing self-propelled diagnostic vehicle. The gDFZ can also measure the vehicle dynamics and overhead line. When in use, the gDFZ is drawn in a train composition consisting of a locomotive, a braking and a control car.

The central system forms the heart of the new vehicle. It not only adopts the interaction with the user, but also the analysis and the persistent storage and display of all measurement data.

The SBB has accepted the tender from SCS for the development of the central system (hardware and software). The successful concept in the public call for tender combines for the first time modular measurement equipment via open interfaces with the technology of a modern data centre and integrates them into a rail car. This flagship project meets all the essential features of an “Industry 4.0” application.

The Microservice architecture allows a modular, flexible, extensible and highly scalable solution. The result is a clear and extensible software environment, which is extremely well suited for further development over the entire life of the gDFZ and which can also be operated efficiently.

SCS also takes on the role of integrator for the overall system. System integration is the key success factor for the entire project. The chosen solution therefore supports the integration of all current diagnostic and support systems through a clear and systematic approach and through open, transparent and scalable system architecture. SCS has extensive experience both in the field of open systems, the integration of third-party systems and the development of “mission critical applications” including maintenance and support throughout the entire life cycle (Life Cycle Management – LCM), for example with the REGA communication system.

We are delighted with this award and the prospect of working with SBB and the suppliers of the other work packages, peripheral systems and vehicle modifications.

Background information on the application:

The SBB infrastructure monitoring business unit is responsible for ensuring the safety and availability of railway infrastructure in compliance with the applicable regulations. The services provided by the monitoring unit are fulfilled using a mix of human expertise (route inspectors) and machine-determined diagnostic and prognostic data (Measurement and Diagnostic Technology). In the medium term the proportion of machine performance will increase due to the expansion of the industrial monitoring of the network and the commissioning of new high-speed lines (Gotthard and Ceneri Base Tunnel GBT/CBT).

Measured test runs are state of the art in railway technology and essential for professional investment management, particularly in the track and traction current asset classes. The measurements in the field of driving technology are mandatory because of the legal and regulatory requirements (including R 22070). Reliable, consistent and meaningful measurement data also provides an important input for short-term diagnostics (monitoring), preventive maintenance and the prognosis of the substance preservation. They form the basis for the medium and long-term maintenance control of the asset classes.

The company Jöhl + Köferli AG offers tailored radio-transmission solutions. Supplemented by a control system, a central communication infrastructure for public transport emerges.

The comprehensive and reliable radio coverage of an area is always hampered by topographical and structural barriers. The single frequency radio network technology designed by Jöhl + Köferli AG solves this problem by using many spatially separated base stations, which guarantee full coverage of the concerned areas. The base stations emit information, which is synchronised on the same frequency. Thus, the frequency spectrum is used economically, allowing the use of simple terminal devices.

The voice connection between the control system and the base stations is achieved via voice-over-IP. The GPS-based synchronisation, designed to keep a precision up to microseconds, allows the simultaneous emitting of the signal at all base stations.

Supercomputing Systems AG (SCS) has developed a universal hardware platform, which is used by the control system (TMC) as well as the radio transmission site (BSC). It is based upon a multi core ARM Cortex A9 processor and the Altera FPGA technology.

Moreover, the Linux software and the FPGA firmware have been developed for the Voice-over-IP communication, the FSK modems as well as the call decoder.

The platform can be used for the integration of a variety of other signal processing tasks.

Jöhl + Köferli AG use the module in a flexible and universal way and expand it according to the different requirement of the public transportation companies. Via a web-based configuration panel, adjustments can be quickly performed.

Compared to regular radiation therapy with X-rays, the proton therapy allows an even more precise localisation of the dose and therefore a high therapeutical efficiency with fewer side effects. Thus, it is highly significant when treating tumors that are located closely to important organs, for instance in the area of the head.

In November 2013, the „Gantry 2“ has started its clinical patient treatment. The applied high speed, intensity-modulated 3D-scanning method is globally unique. We congratulate the PSI Institute on this big success!

The beam control and the continuous monitoring of the beam parameters function with a system cycle of 10 us and ensure the highly precise and safe radiation. We are very pleased, that this innovative system – to which SCS contributed core parts in a common project– is now clinically operative in order to bring forth healing to the patients.
