Value through problem solving

By capturing changes in the condition of cooling water pumps and motors

with vibration sensors, cooling water pump parts can be replaced before

failure occurs. This prevents cooling water pump failure and damage to the

equipment to be cooled.

The number of man-hours spent on patrol inspections can be reduced.

Proposed System Configuration

Wireless vibration sensors are installed at locations where pump and motor

vibration can be measured. The measured vibration values are aggregated

into the Wide Area Monitoring System, and the AI (State Change Detection Service)

learns the vibration values under normal conditions and creates a model.

Whenever there is a change in the vibration values of pumps and motors that

deviates from the normal state, the AI model detects the change. This enables

early detection of changes in the condition of pumps and motors, leading to 

replacement of parts before they fail. By applying this system to cooling water

pumps in various locations in the plant, it is possible to monitor all cooling water

pumps at once to see which ones are showing abnormalities. 

Furthermore, the Wide Area Monitoring System is scalable to enable combined

monitoring of cooling water temperature and pressure, as well as equipment data,

allowing for flexible proposals tailored to each case.
