LIQUID PRESSURE APPARATUS MONITORING SYSTEM

WIPO Patent Application WO/2023/002519

A1

This liquid pressure apparatus monitoring system comprises: a liquid pressure apparatus; liquid pressure sensors (110, 150) for monitoring the liquid pressure inside the liquid pressure apparatus; display devices (230, 250) for displaying the state of the liquid pressure apparatus; a reset device (240) for returning the state of the display devices (230, 250) to initial states; and a control device (180). The control device (180) includes: a first step for determining, on the basis of signals obtained from the liquid pressure sensors (110, 150), the state from among normal operation, maintenance, and use stoppage; and a second step for displaying, on the basis of the determination result in the first step, the state of the normal operation, the maintenance, or the use stoppage on the display devices. With this configuration, it is possible to provide a liquid pressure apparatus monitoring system that can appropriately understand the maintenance period of sealing members and prevent occurrence of liquid leakage.
