Abstract
A pressure measured by a load cell is converted into a digital signal by an A/D converter provided in an analog interface, and is processed by a digital filter provided in the analog interface. A sensor signal processed in the digital filter is transferred to a controller 10 for industrial machinery every transfer cycle via an optical fiber. A digital sampling cycle by the A/D converter is set to be shorter than the transfer cycle.
Claims3
A data transfer apparatus for industrial machinery for transferring a signal from a sensor attached to the industrial machinery to a controller for controlling the industrial machinery,
- wherein the industrial machinery has an analog interface including an A/D converter for converting an analog signal from the sensor into a digital signal and a digital filter for removing noise in the digital signal, and the digital signal in which noise is removed by the digital filter is transferred to the controller via serial communication.
