摘要
一、前言弦式仪器经历了电子管线路、晶体管线路及集成电路的演变.八十年代以来,微型计算机得到广泛的应用,在仪器仪表领域中也出现了带电脑的智能化仪器.本文介绍的是1986年研制成功的智能钢弦仪,它是用Z—80小底板机为核心,包括PIO、CTC和6116RAM、EPROM等大规模集成电路芯片,以及激振系统、多路切换电路组成的.
In the paper, the operating principle of the intelligent vibrating wire readout it's hardware and software are briefly described. It is a secondary measuring instrument used with various vibrating-wire transducers,for example,earthpressure cells and piezometers etc. It is a multi-channel readout which is small, portable, stable and reliable. It is widely used to measure the earth pressure in earth and rockfill dams, dikes and embankments and soil foundations.
