本文从三方面介绍微型机在土工试验中的应用。一、微型机实现对土工试验数据的自动采集和处理数据采集系统由传感器、数据接口、微型机、附属外设组成。二、微型机实现对土工试验的过程控制该系统是在数据采集系统的基础上加入反馈,构成闭环控制,一般由数据采集装置、微型机、D/A转换器、控制电路及伺服装置等组成。三、微型机对试验数据资料的整理 This article introduces the application of microcomputer in geotechnical test from three aspects. First, the microcomputer to achieve the automatic acquisition and processing of geotechnical test data Acquisition system consists of sensors, data interfaces, microcomputers, peripherals. Second, the microcomputer to achieve the process of soil test control The system is based on the data acquisition system to add feedback to form a closed-loop control, generally by the data acquisition device, microcomputer, D / A converter, control circuit and servo devices . Third, the micro-machine test data to organize data
