The future will be a smarter and safer society, to live in

 

Since 1975, Westermo has delivered reliable, industrial communication. As a product manager at Westermo, I see a trend towards a smarter society, in the future.

I see a trend with a higher degree of connection to equipment and people. It will contribute to positive business results for those who see the opportunities and are willing to face the changes.

I believe, with an intelligent network infrastructure, we can improve operations and increase security. The trend towards the Internet of Things (IoT) will provide us with valuable insights and solutions that will lead to improvements and efficiency in many industries. I think that many industries will see the benefits and will use the technology increasingly. In the future we will see affiliated factories, machines, tools, smart electricity grids, roads and vehicles. The driving force will be the many benefits that people and businesses can gain through a higher level of connectivity.

IoT will create a whole new game plan for various industries such as Process
Automation, Shipping, Transportation and others. There will grow up completely new business models based on how people interact and how information is shared between people and processes. The industries will in the future rely more than ever, on the technology, to improve both safety and service.

The IoT will place new demands on network infrastructure in the future. Many applications will require high-speed connections, low latency response, integrated security and flexible and scalable wireless network infrastructures.

Our products and solutions are based on a system approach that makes it possible to achieve a higher level of security while maintaining the quality, efficiency and automation as the foundation. So I am sure that Westermo meets the future demands of the IoT.

Westermo Ethernet broadband bridge for train networks

Broadband Ethernet solution enables significant cost savings in carriage refurbishment projects by reusing existing coupler cabling.

Westermo has launched an Ethernet broadband bridge designed especially for the rail vehicle market. The DDW-002-B1, part of the Wolverine series of industrial Ethernet extenders, can be used to interconnect Ethernet networks within rail cars using the existing cables in the train coupling. This provides considerable savings for refurbishment, negating the need to rebuild or replace the train coupler.

The DDW-002-B1 uses power-line communication technology according to IEEE 1901 and is able to support data communication networks by propagating high bandwidth Ethernet traffic over almost any 2-wire cable. This communication technology is well proven, highly robust and able to negate problems with degraded legacy cabling, such as oxidized connectors.The unit requires no configuration, and plug-and-play simplicity allows rapid installation and commissioning, providing a cost-effective and more robust solution compared to wireless technologies.
The unit has been designed to meet the full requirements of the rail vehicle market and has been tested and certified to meet and exceed EN 50155. It is also approved for track side deployment according to EN 50121-4.
The DDW-002-B1 also has potential for use in a variety of non-rail applications, e.g. involving communication over slip rings. Its compact and robust construction makes it well suited for deployment in areas with severe operating conditions and extreme environments.

By using the highest quality components the DDW-002-B1 delivers extended Mean Time Between Failure (MTBF) figures. Features like a GORE-TEX® membrane in the IP67 enclosure prevent water build-up, and the vibration-safe integrated connector threading, further contribute to high MTBF and long service life.
This product complements Westermo’s comprehensive range of Ethernet backbone and consist network switches already in wide use throughout the rail industry.

“We are proud to receive this recognition of our dedicated work to continuously ensure high quality with our development work. Personally I am very proud of the Software team at Westermo who have worked for years to get us to the point where we are today, where I also see the team's joint dedication to take this quality assurance work even further. I am also grateful for the support of our fellow researchers from the US and from Mälardalens Högskola in Västerås, Sweden”, says Peter Johansson who is Manager for Software Solutions and Software Test at Westermo.

The main author of the research paper, Per Erik Strandberg was on site in Ottawa to present the research work. The paper has been developed together with Thomas J. Ostrand (USA) and Elaine J. Weyuker (USA) and Daniel Sundmark and Wasif Afzal from Mälardalens University (SWE). "The knowledge acquired and the new contacts established during the very intensive conference week, has triggered our curiosity beyond the ideas we already had.", says Per Erik Strandberg, Test Lead at Westermo.

Reliability is crucial in any industrial and infrastructure process control system. It is important that the data communications for these systems will work at all times. The continuous work with software test at the Westermo Research and Development centre contributes to increased system reliability.

The Automated System Level Regression Test capabilities provide the ability to pinpoint problems long before a product is released. “This way of testing automatically provides early feedback with diversified results tailored for each individual developer without the need to manually choose what to test and when.”, says Peter Johansson.

By complementing automated testing with other test measures, for example risk based testing and exploratory based testing, Westermo work to ensure the highest quality with the combination of automation and human intelligence.

ISSRE is an academic conference with strong industry participation running since 1990 and covering reliability engineering for software. ISSRE interests are in reliability, availability, safety, security and quality of software. ISSRE is sponsored by the IEEE Computer Society.

Dynamic automated risk based test selection - test efforts where it matters most

A key factor of quality assurance at Westermo is dealing with complexity. Infinite possible combinations in terms of new and existing features, supported protocols, supported hardware platforms, network topologies and solutions is the challenge we meet.

At the same time we want to be flexible when developing new features and to get rapid feedback. We manage this with feature-driven development and continuous integration.

With our automated system level regression test capabilities, we have the ability to pinpoint problems long before product release with early feedback to developers. With this we are able to automatically provide diversified results tailored for each individual developer without the need to manually choose what to test and when.

We have our own developed test framework that completely automatically selects what tests to put into each individual test suite that the framework. This selection is based on quantified risks that changes along with what is about to be tested. The test framework also maps test cases towards an arbitrary number of physical test systems, each with its different set of DUTs. We have built the capability into the test framework to be able to test different network topologies that even comprise of subsets of our physical test network topologies. This helps us mitigate risks and manage the complexity that comes from an infinite number of possible test setup combinations.

At the CODE-STHLM Conference (Continuous Delivery and DevOps Conference Embedded Edition) I will talk about how we at Westermo continuously ensure high quality of our software development throughout the development process with our automated system level regression test capabilities.

Please come listen to my speech at the conference, to learn how this works for real and come see me afterwards to discuss it with me. I am looking forward to meet you there!
