Hankook Tire announced it has developed an AI (Artificial Intelligence) and IoT (Internet of Things) based production monitoring system, called Hankook Condition Monitoring System (CMS+), which helps detect and predict any production line abnormalities before they become a problem.
Facility abnormality prediction systems like CMS+ typically use a vibration sensor attached to key components of the equipment. This requires experts to analyze the information collected by the sensor and determine if there are any symptoms. However, to improve accuracy in anomaly detection and reduce response time compared to the existing system, Hankook leveraged AI and IoT technology to develop CMS+, its newest facility abnormality prediction system.
The CMS+ uses a three-step AI algorithm which proceeds through “Next-generation wireless-based IoT module,” “Gateway,” and “Server.” This enables data analysis with precise prediction three to four times greater than the existing system.
During the first step that utilizes the IoT module, CMS+ collects and analyzes data every second whereas the conventional method collected sensor data only at regular intervals. It was impossible to store vast amount of sensor data transmitted in real time due to limitation in server capacity; however, the AI algorithm equipped in next-generation wireless-based IoT module and gateway made it possible to automatically sort out and selectively store the data suspected of abnormalities. This original AI algorithm was developed in cooperation with KAIST.
At the Gateway and Server level, CMS+ conducts an in-depth analysis of the data collected based on deep learning technology. It analyzes different types of data all together including sensor data, temperature, and operational information to predict abnormal conditions of the facility in advance. It is also equipped with a real time alarm system based on wireless communication technology. In case of anomalies, the system immediately alarms the manager, which allows the manager to take appropriate action much faster.
Hankook adopted the newly-developed system to factories in Korea and is in process of applying to all factories around the globe.
