摘要

Invocon, Inc.has developed a next teneration data acquisition and communications network to be deployed in, on, and around space structures under construction. This Wireless Instrumentation System (WIS) is a highly integrated remote data acqusition system for use in a wide variety of distributed sensor applications. Typical applications indluce modal analysis, condition-based maintenance, structural monitoring and manufacturing process control. Designed for NASA Johnson Space Center, the system will monitor criticaol temperatures during the assembly of the international SPace station (ISS), and verify structural dyamics models for the ISS on-orbit. Similar units are used on Navy aircraft for flight testing data acquisition. The relaying network is automatically configured by the imbedded system software, which provides for simple installation and consitent operation in almost any enviromentat. The ability to reloacate the data acquisition electronics near the sensors decreases setpu costs and reduces "noise" unduced on analog signals by long wires. The first WIS hardware items flew as a Risk Mitigation Experiment of STS=83 in Overmber of 1996 and STS-94 in July of 1997. The next phase of WIS involves development of the IWIS or Internal wireless Instrumentation System and the SWIS or SHuttel Wireless Instrumentation System. IWIS, the internal system, will be depolyed by the astronatus inside the partially completed ISS to collect data on the impulse response of the sructure. The Shuttel-based system (SWIS) will provide units installed on the outisde of the Station modules prior to launch. As the ISS modules are removed from the Cargo Bay and transferred to the assebmly point on the Station, the SWIS data gathering units will transfer sensor data from the ISS module to the Crew Compartment of the Shuttel where the data will be down-lined to Mission Control for use by the flight controllers.
