Document Type and Number:
WIPO Patent Application WO/2018/110155
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a facility monitoring system whereby data volume is reduced and recording of waveform data for a long period of time is possible. In order to achieve this purpose, the present invention is characterized by being provided with an analog waveform rendering unit, a waveform recording unit for recording a waveform rendered by the analog waveform rendering unit, a data compression unit for compressing data recorded by the waveform recording unit, a data transfer unit for transferring data compressed by the data compression unit, a data storage unit for storing data transferred by the data transfer unit, a data reconstruction unit for reconstructing an analog waveform from the data stored in the data storage unit, a data analysis unit for analyzing data from the data reconstruction unit and determining the state of a device, a device state monitoring unit for monitoring a device state on the basis of data from the data analysis unit, and a device state display unit for displaying the device state.
