로드 셀 계측용 원격 모니터링 시스템 개발

Abstract

In the present work a weight measuring instrumentation system in which data conversion and a series of signal processing were totally equipped were designed. The 16 load cell were incoming sensors and each output of the strain gauge was amplified and filtered for proper analog signal processing. Several measuring instrumentation OP amps and general purposed OP amps were used. The 12 bits A/D converters converted analog signals to digital bits, and a PIC microprocessor controlled the 16 channels of strain gauges. RF RS232 modules were used for wireless communication between the PIC microprocessor and an ethernet host for a remote sensor monitoring system development.
