MAPREX is a software application for process condition monitoring based on the Self-Organizing Map (SOM) neural network. It provides advanced monitoring tools in a highly versatile way, allowing to look for the causes of a system malfunction or the factors which have an influence in the final product quality in complex systems as a previous stage for further more specific condition monitoring prototypes. Its main features include capability to acquire and store data from field sensors, real-time displaying of the signals and their spectra, real-time feature extraction and displaying, and state trajectory visualization based on SOM, also in real time.
