Automotive data recorder and signal replay system
The request was for a complete solution for portable recording of dynamic mixed mode (analog and digital channels) data during test drive. The data should be replayed and analysed later in Research and Development laboratory. A full working system including operation software was needed..
Who is the customer?
Large European manufacturer for sensors, sensor related electronics and software. End applications are automotive, industrial processes, plastic processing and biomechanics. This application is used at a R&D department specified in mechanical sensors for automotive testing.
Requirements of the customer
A portable and rugged recording and replay system based on Windows 7.
Current solution and disadvantages
Currently standard automotive data loggers are used. Disadvantage of this and similar solutions is the lack of replay functionality. To allow replay the customer would need a separate system with different software and possibly the need for programming data conversion.
Secondly there are not many solutions on the market that allow to replay mixed mode data of analog and digital channels simultaneously.
Spectrum solution and advantages
The offered and purchased Spectrum solutions consist of:
The synchronization star-hub is mounted on the fast digital i/o card M2i.7010. This allows to either synchronize digital i/o + digitizer for synchronous acquisition of 8 analog channels and 16 digital channels or it is possible to synchronize digital i/o + waveform generator for synchronous replay of 4 analog channels and 16 digital channels.
The Spectrum card based solution was able to fulfill the customers requirement in the competition for a reasonable price. The Spectrum solution was the only system with playback capabilities.
