Pain Points

Financial downtime losses caused by unpredicted failures of the stoker crane robots in a panel factory is huge.

Panel factories want to cost-effectively prevent unpredicted stoker crane robot failure without increasing their annual maintenance cost on the robots.

Challenges

Real Engagement

texol provided professional training course to our customers to build up a robust AURORA monitoring system following the engagement process described below by themselves. The gear boxes are the most fragile components in a stoker crane robot. The gear teeth often wear and then break.

First of all, users collected the design diagram of the gear boxes and calculated the theoretical spectrum features of gear teeth wear. Meanwhile, they used DynaView spectrum and feature analyzer to collect the vibration signals of gear boxes when they were in operation. In DynaView, they observed the vibration signals to define a signal cleaning strategy to the unsteady-state signals. They also investigate the theoretical spectrum features of gear teeth wear in a real spectrum.

Secondly, users deployed couple endnodes which have been configured in the spectrum features of gear teeth wear and other fail-modes to all gear boxes in dozens of stocker crane robots. They have successfully observed the long-term trends of these features in DDMS. They also have formulated a set of alert levels of the health condition which are very robust and then deployed them to the smart endnodes using DDMS.

Furthermore, big data analysis team fetches health feature data of robots using MQTT protocol to optimize the production and maintenance schedule of all stocker crane robots in one production line.

Benefits

Dozens of stoker crane robots in one panel plant are now being monitored by Aurora system. The accuracy is closed to 90%. A panel plant can save 300 to 500 thousand USD yearly by preventing unpredicted failures of the stoker crane robots.

Who texol

texol has been focusing on vibration and acoustic research more than 10 years.
