Mobile impact hammer test (Beckhoff CX7000, NI-9232)
Initialises the system, runs tests in a loop and starts the life bit monitoring.
Mobile sound test stand with physical hardware: a Beckhoff CX7000 controller and an NI-9232 measurement module with a microphone. After the hammer blow the microphone signal triggers the measurement; RMS and FFT are calculated and the spectral maxima in three frequency bands (2–3 kHz, 7–8 kHz, 14–15 kHz) are evaluated. A life bit mechanism monitors the connection to the controller in parallel and raises an alarm if it fails. A screencast of the configuration is available.
Workflows in detail
-
Main
Initialises the system, runs tests in a loop and starts the life bit monitoring.
Start → init → set hammer time → test loop (start trigger → call MobileAnalysis → evaluation output → store) → call CX_SendLifeBit → end.
-
CX_SendLifeBit
Connection monitoring towards the controller with an alarm.
Start → life bit loop (toggle bit → if not set: send alarm → delay) → end.
-
MobileAnalysis
Triggered microphone measurement with acoustic evaluation.
Start → signal trigger microphone → microphone measurement → analysis "Basic Evaluation" → end.
-
Basic Evaluation
Characteristic block.
Characteristic start → RMS → FFT → max 2–3 kHz → max 7–8 kHz → max 14–15 kHz → characteristic end.
