Standard test method for yarn number using automatic tester 用自動試驗(yàn)機(jī)測定紗線支數(shù)的標(biāo)準(zhǔn)試驗(yàn)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(jī)、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(jì))和ccd攝像機(jī)作為圖像傳感器完成自動采樣,用計(jì)算機(jī)進(jìn)行控制與數(shù)據(jù)處理,從而實(shí)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(diǎn)。
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(xì)介紹了指示表自動檢定儀的機(jī)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(jì),闡明系統(tǒng)是在計(jì)算機(jī)的控制下,由計(jì)算擬通過i o卡、步進(jìn)電機(jī)驅(qū)動器,驅(qū)動步進(jìn)電動機(jī),由步進(jìn)電動機(jī)通過傳動機(jī)構(gòu)推動被檢指示表的測桿移動,從而實(shí)現(xiàn)測桿的微量進(jìn)給。
