Title:

Industrial Application of Time Sensitive Networking

Regular computer networks can slow down unexpectedly. This can cause serious issues for time sensitive tasks, such as playing audio or communicating sensor information in a self driving car. Time sensitive networking protocols eliminate this problem by providing guaranteed throughput and latency over a regular Ethernet network. This project demonstrates the value of a time sensitive network in an industrial system. We suspend a rope between two motors which communicate with a controller over a time sensitive network. The controller keeps the motors in sync with each other, which produces a standing wave in the rope. We produced an embedded application that allows the motors to communicate over a time sensitive network. This includes the creation of a standards compliant TSN networking stack and algorithms that use the provided network to communicate data and control signals to synchronize the motors. Our implementation of the TSN protocols and control algorithm is open source, meaning it can serve as an example or a starting point for other similar projects. This application runs on microcontrollers. Without reliable, low latency communication between the motors, the synchronization between the components would be lost and the rope would lose its standing wave. This provides a visual demonstration of how the addition of time sensitive networks can allow industrial systems to communicate and stay in sync.
