Research on the Instrument on Network(ION) and Its Key Technologies

The instrument on network is intended to bridge the "gap" between information highway and nature and solve the problem of "connection of tracks" between the test instrument and information highway, with "The Measure and Control Network" plus "Sensors" as its basic model. The paper puts forward an open architecture of ION based on network interconnection, expounds basic definitions and connotations of ION in depth, and provides a tentative analysis of such key technology issues as unified time, time determinability transmission, etc.
