Title:
START TIME SYNCHRONIZATION SYSTEM OF VIBRATION MEASUREMENT
Document Type and Number:
Japanese Patent JP2022123382
Kind Code:
A
Abstract:
To provide a system capable of suppressing deviation of starting time for measuring vibration even if a PLC device is used.SOLUTION: A system includes: a signal transmitting part 2 for transmitting a measurement start signal of vibration; plural measurement parts 3 for performing measurement when receiving a measurement start signal; a control part 5 for receiving signals from the signal transmission part and sending the measurement start signal to the measurement parts by receiving the signal; and a PLC device for performing processing of information used for power line communication between the signal transmission part and at least one measurement part. The control part is configured to control measurement start time of a specific measurement part so as to be synchronized with measurement start time of another measurement part by sending a measurement start signal to the specific measurement part after a delay of predetermined time from timing when receiving signals from the signal transmission part.SELECTED DRAWING: Figure 2
