Title:
MEASURED VALUE MONITORING SYSTEM, AND MEASURING DEVICE
Document Type and Number:
Japanese Patent JP2023167660
Kind Code:
A
Abstract:
To provide a measured value monitoring system capable of rapidly grasping a change in a situation inside a plant, while realizing improved power saving.SOLUTION: A measured value monitoring system comprises an indication value acquisition device for outputting a measured value; and a monitoring device for transmitting a down-link signal to the indication value acquisition device, while receiving an up-link signal from the indication value acquisition device. The indication value acquisition device comprises an acquisition part, an up-link transmission control part for transmitting the measured value to the monitoring device in first transmission timing (Tx) that is periodical, a down-link reception control part for shifting the down-link signal from the monitoring device to a receivable state in first reception timing (Rx) after the first transmission timing (Tx), and a state control part for controlling a state between a normal state and a low power-consumption state. The up-link transmission control part transmits the measured value in second transmission timing (tx) different from the first transmission timing (Tx), when the down-link reception control part receives the down-link signal.SELECTED DRAWING: Figure 7
