Distributed and adaptive data acquisition system and method
First Claim
1. A method for establishing communications between a distributed data acquisition system and a plurality of sensors and a controller, wherein the data acquisition system comprises at least one micro-computer, the method comprising:
- searching for sensors assigned to a micro-computer in the data acquisition system;
requesting the assigned sensors to send identifier information to the micro-computer;
using the identifier information and for each assigned sensor, selecting a sensor communications protocol from a library in the micro-computer corresponding to the assigned sensor, and generating a work list of the selected communications protocols to be used in communicating with the sensors assigned to the micro-computer.
