Standard test method for yarn number using automatic tester 用自動試驗機測定紗線支數(shù)的標準試驗方法
Automatic tester for dial gauges is an intelligent instrument unified mechanism light and electronic . the grating displacement sensor that has high accuracy ( length gauge ) and camcorder is image sensor consummately automatic sampling is adopted . it is controlled and handled data by computer . so it has realized the intelligence and automation of calibrating course . the instrument has features of high precision , efficiency , flexible and convenient in operation , and so on 指示表自動檢定儀是機、光、電一體化的智能化儀器,采用了具有高精度的光柵位移傳感器(長度計)和ccd攝像機作為圖像傳感器完成自動采樣,用計算機進行控制與數(shù)據(jù)處理,從而實現(xiàn)了檢定過程的自動化和智能化,使儀器具有高精度、高效率、操作靈活、使用方便等特點。
This paper has introduced the design of the instruction mechanical system , servo control system and image collection and processing system of the automatic tester for dial gauges in detail . it is illuminated that the step motor with the card of i / o and the step motor actuator is driven by computer . the step motor drives the surveying rod of automatic tester for dial gauges through the transfer machinery and realizes micro - displacement of the surveying rod 本文詳細介紹了指示表自動檢定儀的機械系統(tǒng)、伺服控制系統(tǒng)、圖像采集與處理系統(tǒng)的設(shè)計,闡明系統(tǒng)是在計算機的控制下,由計算擬通過i o卡、步進電機驅(qū)動器,驅(qū)動步進電動機,由步進電動機通過傳動機構(gòu)推動被檢指示表的測桿移動,從而實現(xiàn)測桿的微量進給。
