Abstract:
A system for remotely monitoring at least one machine, said system comprising:a central computer system including a central database that stores trend parameter signals and an amplitude spectrum; an on-site computer system having an on-site database that stores said trend parameter signals and said amplitude spectrum, a central processor and an auxiliary processor; means for sensing process data related to said machine, said means for sensing process data generating a process data signal that is fed to said central processor and said auxiliary processor; means for sensing dynamic data related to said machine, said means for sensing dynamic data generating a dynamic data signal that is fed to said auxiliary processor, wherein said central processor processes said process data signal to generate said trend parameter signals and said auxiliary processor processes said process data and dynamic data signals to generate said amplitude spectrum; and a communication link between said central computer system and said on-site computer system, wherein said trend parameter signals and said amplitude spectrum are logged into said on-site database at a first rate and are logged into said central database at a second rate, said first rate being greater than said second rate.
