Machine data acquisition system with data compression
First Claim
1. A data acquisition system, comprising:
- a sensor disposed on a machine and configured to produce a signal indicative of an operational parameter of the machine;
a data processor and controller configured to convert the signal into a plurality of parameter data points;
a primary data circular buffer disposed on the machine and configured to store the plurality of parameter data points; and
a variable resolution circular buffer disposed on the machine and configured to store a compressed parameter data point calculated from the plurality of parameter data points.

Abstract
A machine data acquisition system is disclosed. The data acquisition system may include a sensor disposed on a machine and configured to produce a signal indicative of an operational parameter of the machine. The system may also include a data processor and controller configured to convert the signal into a plurality of parameter data points. The system may further include a primary data circular buffer disposed on the machine and configured to store the plurality of parameter data points. Additionally, a variable resolution circular buffer may be disposed on the machine and configured to store a compressed parameter data point calculated from the plurality of parameter data points.
