A real time system based on Concurrent’s cross-point parallel multi-processor architecture is soon to take over data acquisition, post processing and analysis at the Environmental Simulation Centre of SNPE (Societe Nationale des Poudres et Explosifs) near Bordeaux, France.

Harnessing a Concurrent Maxion 9250, it’s to replace an existing system on vibration testing and research. It’s being engineered in-house by Concurrent and ISTAR in Paris as an integrated, turnkey system – including integration with the facility’s plant sensors, anti-alias filters and other existing retained instrumentation systems.

According to Concurrent, hardware-wise the system comprises two closely-coupled CPUs handling 64 data acquisition channels. Acquisition rates are 150kHz per channel at 16bit resolution, and it interfaces to a range of transducers, including accelerometers, thermocouples, strain gauges and pressure sensors.

There are three main software packages – all Concurrent/ISTAR signal analysis standards for handling tests involving random signals, swept sine and transients. There’s also the usual set-up and engineering configuration tools. It’s all UNIX-based, with a graphical front end harnessing OSF Motif to deliver four windows providing plant status, acquisition curve plots and so on.

Interestingly, the system has been designed to handle two separate tests, running simultaneously and independently – sharing computing across the cross-point processor resource for maximum throughput.
