WIPO Patent Application WO/2018/117164
Kind Code:
A1
Abstract:
Provided is a plant equipment diagnostic system with which indicators of an abnormality in plant equipment can be suitably detected, while reducing the power consumption of sensor modules and extending the service life of batteries. This plant equipment diagnostic system 1 is equipped with one or more sensor modules 3, and a state diagnosis device 5. Each of the sensor modules 3 is equipped with a state detection sensor 11, a data storage unit 15, a data reading unit 17, a data conversion unit 19, a transmission data selection unit 21, and a wireless communication unit 23. When the state diagnosis device 5 diagnoses the plant equipment as being in a normal state and a selection command has not been received, the transmission data selection unit 21 selects the output from the data conversion unit 19 as transmission data, and when a selection command from the state diagnosis device 5 is received, the output from the data reading unit 17 is selected as transmission data.
