Vital communication systems design for signal engineers

vital communications design for railwaysPre-Requisites

There are no formal pre-requisites for the course. Graduate level electrical engineering knowledge is assumed but concepts are explained from first principles.

About the Course

Vital communications design for railways is a three-day course.
This includes practical demonstrations, course workbook, final assessment, and a certificate upon successful completion. We run public courses or can arrange delivery in your workplace – contact us for more details.

The following topics are covered:

  • Serial data characteristics, message construction, integrity.  Buffering, latency, packet loss, packet identification.
  • Serial data interface standards: RS-232, RS-485 and their current equivalents.  How many wires do you need for each interface and what do they do? Isolation, ground references and signal return.
  • IP protocols - TCP and UDP. Addressing, packet delivery principles. Latency, Time to Live, round trip time, error detection and correction. Ports and sockets. Conversion from serial interfaces to IP.
  • Copper cable characteristics: including twisted pair, Cat 5 etc, shielding and grounding. What limits cable length. Copper link design.
  • Optical fibre characteristics: single mode, multimode, reflection, refraction, dispersion. Basic optical link design.
  • System design for resilience. Implementing serial data and IP systems. Addressing, protocol conversion. Typical data requirements.
  • Practical exercise designing, building and testing a system with optical fibre and IP connections. Fault finding and data log analysis.

Course Outcomes

On the successful completion of this course, you will have learned how to design and document vital communication systems operating on copper and optical fibre media. You will understand serial communication interfaces, IP connections, basic optical system design, implementation and testing. Your confidence in working with these systems will be based on understanding the principles and hands-on exercises.

Who Should Attend?

Signal designers, design verifiers, installers and commissioning engineers.
