Title:
MONITORING SYSTEM, MONITORING DEVICE, AND MACHINE MONITORING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/080157
Kind Code:
A1
Abstract:
This monitoring system comprises: a monitoring device that detects the value of a monitored item of a monitored machine; and a higher-level apparatus. The monitoring device can store inherent information including a threshold value for the monitored item, said threshold value serving as a trigger to start a prescribed action. The higher-level apparatus is provided separated from the monitored machine, and collects monitoring-related information from the monitoring device, said monitoring-related information including the inherent information and detection information. Additionally, the higher-level apparatus appropriately collects the monitoring-related information from the monitoring device, and saves the inherent information if the same is not yet saved. The higher-level apparatus compares installation condition information collected from the monitoring device and saved installation condition information, and if there is a difference, transmits response information to the monitoring device, said response information at least including a portion of the threshold value or values of the saved inherent information, said portion having not been included in the inherent information collected from the monitoring device. Among the threshold value or values received from the higher-level apparatus, the monitoring device stores at least the portion that is not yet stored.
