| Abstract: | The paper introduces to us a strain-gauging apparatus on the bridge,which can precisely measure the strain of viaducts. In this apparatus, a new metal strain plate is used as the sense organ and the Cygnal F020 single chip microcomputer is used as an intelligent part. The apparatus is small and portable,and has friendly operational interface and high precision to 0.01. It can not only work alone, but also operate with a notebook or a personal computer by the USB adapter to display, print and analyze the gauging result. |
