Our Solution

Predictive Maintenance Solution–

• Real time connectivity with factory floor Sensors to gather real time machine data.

• Machine data is matched against pattern library to understand faulty pattern for a given time interval.

• Any match of faulty pattern in a given time interval, an action is initiated.• Email Notification

• Work Order Initiation in Maximo

• Web Service Initiation

• Sensor data is visualized on Mash zone NextGen.

This solution is built using below Integration products and their respective components.

• Software AG – Apama (For Complex Event Processing)

• Software AG – Universal Messaging (To receive events from sensors and send to Apama)

• Software AG – Mashzone NextGen (For visualization of sensor data including fault patterns.)
