The AFGL Vibro-Acoustic Measurement System,

Abstract

The vibro-acoustic environment at V-23 on Vandenberg AFB must be monitored during STS launches to insure integrity of the ground support structures and associated equipment. Of particular concern are three mobile buildings: the Payload Changeout Room (PCR), the Shuttle Assembly Building (SAB), and the Mobile Service Tower (MST). Limited power and communications lines in both the park and forward positions, plus a desire for near real time data display, present an interesting engineering problem. One solution is the Air Force Geophysics Laboratory (AFGL) designed and fabricated Vibro-Acoustic Measurement System (VAMS). The VAMS is a distributed computer network designed for monitoring environmental motions. The heart of the system is a master control unit to be centrally manage the network as well as to continually record data. Closely coupled to the master is an array processor for the massively parallel data processing required in digital signal processing. Five slave units are coupled to the master. Each slave can handle 16 sensors; the system capacity is 80 channels. The network will function using only one voice grade telephone line between the master and each slave.
