Apparatus monitoring system and apparatus monitoring method
First Claim
1. An apparatus monitoring system which monitors an apparatus installed in an electric power installation and is connected to a communication network, said apparatus monitoring system comprising:
- sensors, provided on said apparatus, for measuring said apparatus to output monitoring signals that vary according to the state of each part of the apparatus;
a data acquisition and transmitting unit including conversion means which receives the absolute time, to which said sensors supply the monitoring signals, which samples the monitoring signals and converts the sampled signals into absolute-time-tagged digital monitoring data and transmission means for transmitting the digital monitoring data to the communication network; and
a data display unit which receives the digital data from said data acquisition and transmitting unit via said communication network, converts the digital data into display data related to the state of said monitored apparatus, and displays the display data.

Abstract
A data acquisition and transmitting unit samples the signal indicating the apparatus state quantity from a sensor provided on an apparatus, converts the signal into absolute-time-tagged monitoring data S(t), stores the data S(t), and transmits the data S(t) to a network. A digital protection and control unit takes in the quantity data E about the system of the apparatus and the operating state data P about the apparatus, converts these data into absolute-time-tagged data E(t) and operating state data P(t), stores these converted data, and transmits these data E(t) and P(t) to the network. A data display unit receives the data S(t), E(t), and P(t) from the data acquisition and transmitting unit and digital protective and control unit via the network and displays the state of the apparatus on the basis of the data S(t), E(t), and P(t).
