摘要
便携式智能数字测微仪是一种新型的高精度计量仪器。电路设计上采用了大规模集成电路元件和液晶显示。该量仪还采用了80C31单片微机系统,具有超限报警、数据平均处理等功能。该量仪功耗低、体积小、方便实用。本文介绍了该量仪的工作原理、技术指标、电路设计和微机设计特点等。
The portable intelligent digit display micrometer is a new type of micrometer with high accuracy. The Largescale integrated circuit and LCD are used in the circuit design. This micrometer, which is equipped with a 80c31 multi-functions such as data averaging, alarming when beyond its limits,etc. It has much smaller size and lower power consumption, and can be operated conveniently. The principle, technical index, circuit design, and microcomputer disign of the micrometer are presented.
