Multiple sensor system
First Claim
1. A displacement sensor comprising a measurement value acquisition unit for acquiring a displacement measurement value, a measurement value processing unit for processing the displacement measurement value acquired by the measurement acquisition unit, and a process result output unit for outputting a result provided in the measurement value processing unit, whereinthe measurement value processing unit processes at least three process categories including at least waveform shaping which removes noise from the acquired displacement measurement values to form a shaped waveform, characteristic point extraction which extracts a characteristic point from the shaped waveform, and calculation which performs a predetermined calculation based on the extracted characteristic point, in sequence, andeach process category can select one or more process programs from a plurality of sectionalized process programs and a process algorithm is determined by designating an execution sequence of selected process programs.

Abstract
An extension unit provided adjacent to an amp unit comprises a measurement data accumulation memory, a measurement data acquiring part for acquiring measurement data coming through a transmission line and accumulating it in the above memory, a data analyzing part for analyzing an accumulated series of measurement data according to predetermined algorithm, a determining part for determining a data analyzed result, and an output part for outputting a control signal corresponding to a determined result to the outside. A plurality of process programs in which measurement algorithm is segmentalized are incorporated in the extension unit and a process program is selected according to a command from a personal computer and the selected process program is performed in a predetermined order.
