Research On Measurement And Control System Of Dilatometer

In the industrial measurement, research of national defense and other fields, precision measurement technology has very wide application. In recent years, precision linear displacement measurement is widely used in laser interferometry, in order to achieve the measurement automation, corresponding control systems need to be resolved.The content of the topic has made a more comprehensive elaboration in the article, including system hardware design and software programming. Through the plan authentication, the control system of survey has been carried on the system design, the current technology of high accuracy linear displacement has been carried on the simple introduction , the feasibility of automatic control system for measure length is studied in this topic.This topic,s main goal is to realize the linear measure automatic control system, automatic control of dilatometer and the measurement result adjustment realization are researched, the design of motors, control panel and displacement sensing circuit is involved. 5529A,s survey control procedure and picture sensor,s control procedure are compiled.In this paper, there are very comprehensive expositions on the task of problem,. there is a simple exposition on the current high precision displacement measurement technology, and on feasibility of the automatic control system. also, a high precision measurement solution is introduced, and the automatic control system is designed, including motors control circuit to achieve bar and track movement, serial communication control circuit, the sensor control circuit. Finally system procedures such as SCM control procedures, motor drive control procedures, serial communication procedures,,5529A's communication procedures, image sensor control procedures, images processing procedures for gaining straight center, system control procedures in PC.
