Abstract

A data acquisition and processing system and method includes one or more distributed and expandable data acquisition nodes for processing large amounts of data. Each data acquisition node includes a core group of primary boards electronically connected together via a vertical bus capable of providing intra-node communication between the primary boards. A secondary board horizontally connected in association with the primary board via a horizontal bus provides inter-node communication or instrumentation interfaces to sensors or other application specific instruments. A master control unit associated with a graphical user interface communicates with the data acquisition nodes via a communication protocol to permit high speed exchange of information and to display information reported from the acquisition system. A storage controller associated with a node controller controls storage of data associated with the data acquisition nodes on a database in a remote location.
