Article: Testing of information technology systems
Passenger information systems, video, loudspeakers, etc.
Our services can be rendered in our IT laboratory and in a wide range of rolling stock. We can assist you with the questions and issues you have in the area of information technology:
- Prototype testing
- Preliminary checks to avoid rolling out faulty software and data supplies in production systems
- Verification of the modularity of components by testing for compliance with specified interfaces and protocols
- Product certifications for establishing procurement alternatives
- Reduction of testing effort in production systems by provisioning appropriate testing, reference and simulation environments
- Reproducibility of test results safeguarded and sufficient in-depth testing according to the requirements specification (tender specification)
- Functional verification documents for borderline cases that require a great deal of outlay to check in passenger service operation.
DB Systemtechnik is QMS certified to the ISO 9001 standard.
Our tests
Details:
Our wide range of IT-based test and acceptance procedures for components of rail vehicles and stations encompasses the following areas:
- Passenger information systems (FIS), e.g. data supplies, indicators, loudspeakers, call stations
- Sales systems in trains (ticket cancelling and ticket machines)
- Transit traveller information systems (RIS) for dynamic travel time estimates, delay notifications and automatic onward connection displays
- Video surveillance systems
- Bus systems and vehicle networks, e.g. data networks and train and vehicle bus protocols
- Public adress (PA) systems (e.g. standard testing of speech intelligibility)
- Automatic passenger counting systems (APCS)
- Vehicle location positioning (satellite-based and odometric)
- Radio interfaces (GSM-P/GPRS/UMTS/LTE)
Our test procedures
Details:
- Determination of recording quality and illumination level of video surveillance equipment in rail vehicles in accordance with DIN EN 50132-7 (Rotakin method)
- Measurement of speech intelligibility using STIPA and RASTI measurement methods in accordance with DIN EN 60268-16
