Vibration information transmission apparatus and vibration monitoring/analyzing system
First Claim
1. A vibration monitoring/analyzing system for transmitting vibration data transmitted thereto from a vibration information transmission apparatus to an analysis/diagnosis means or/and a vibration monitoring means for monitoring an abnormal vibration through said digital network and giving a warning, wherein:
- the vibration information transmission apparatus comprises at least one transmitter provided as an apparatus for outputting vibration information transmitted thereto from a vibration sensor for detecting vibration of an object to be measured to a digital network, said transmitter having in the same casing;
a transducer circuit for converting said vibration information transmitted thereto from said vibration sensor into an analog electric signal;
an A/D conversion circuit for converting said analog electric signal transmitted thereto from said transducer circuit into a digital signal; and
a network interface for outputting said digital signal transmitted thereto from said A/D conversion circuit to said digital network;
the vibration monitoring/analyzing system further comprising;
a means for generating a synchronizing trigger signal at a reference position in a rotation phase of a rotating machine to be measured, wherein each transmitter has an input portion of said synchronizing trigger signal transmitted from said means for generating said synchronizing trigger signal.

Abstract
A vibration information transmission apparatus for improving efficiency of field wiring of a vibration monitoring/analyzing system includes transmitters (11-1 to n) for converting vibration information from vibration sensors (2-1 to n) for detecting vibration of an object to be measured, into an electric signal and outputting the electric signal to a digital network (DN). The transmitters (11-1 to n) includes in the same casing, a transducer circuit (18) for converting the vibration information from the vibration sensors (2-1 to n) into an analog electric signal, an A/D conversion circuit (19) for converting the analog electric signal from the transducer circuit (18) into a digital signal, and a network interface (20) for outputting the digital signal from the A/D conversion circuit (19) to the digital network (DN).
