46 Focus | Performance monitoring so that engineers do not need to know the details of the underlying ML framework or the process of squeezing it into a microcontroller, a process known as quantisation. Models are created using an analytics engine that automatically generates an optimised, device-ready model to maximise the accuracy within the specified resource constraints of the target hardware. Resulting models are automatically translated into embedded code – with options for binary, library or full source output – delivering real-time inferencing that executes directly on the target microcontroller. This could be for monitoring any kind of data stream, from audio from a motor to data from a strain gauge, fuel sensor or pressure sensor. However, developers can also train networks with data from their own systems, and port those models to a microcontroller handling the quantisation process. Conclusion New protocols such as Cyphal are enabling sensors to be added quickly and easily to monitor the performance of uncrewed systems, while AI and TinyML are providing new ways to analyse the data and provide alarms to an operator or to the system itself. New materials such as graphene are enabling more sophisticated sensors in different places in the system, and providing new ways to connect up those sensors to monitor their performance more effectively.
