OTI has developed and is producing a shipboard signal processor for interfacing noise and vibration sensor signals with a digital computer and narrow‐band spectrum analyzer. The Monitoring System Signal Processor (MSSP) provides for 144 accelerometer and 6 hydrophone inputs, as well as A/D rand D/A conversions of auxiliary dc, ac, and discrete signals. The MSSP scans the input channels and conditions the incoming signals which are then fed through a bandpass filter and selector. The selected band is connected to a variable gain amplifier. The scaled analog data are low‐pass filtered, sampled, and converted to digital format. A block of 2048 digital samples are then stored and block transferred to the computer. The computer transfers the data to a separate spectrum analyzer for narrow‐band frequency conversion and13 octaveband generation. The computer provides for storage of threshold values for various ship speed ranges, and generates alarms and displays for operator action when these limits are exceeded. The system can be reconfigured to incorporate the frequency transform function into the MSSP. In conjunction with a small computer and suitable peripheral equipment this would comprise a compact NVM system for shipboard or industrial applications.
