C12106 and 436 numbers are typed on the rod 測桿里寫c12106和436的文字。
Leveling pole rod or staff 水準測桿
There is a roof in this preserved place . but the locomotives are soiled by white paint and dusty 我發(fā)現在測桿上還寫著39643的數字,是日本國鐵蒸汽機車時代的號碼。
Precision checking is the precondition of the machine precision . it includes probe checking and rotor checking . probe and reposition data can be modified through checking 對測量儀進行精度校核是保證測量精度的前提,精度校核分為測頭校核與回轉軸校核,通過測頭校核可修正測頭、測桿以及復位參數。
The principle 、 configuration and characteristics of the measure and control system in the grinding circuit with hydrocyclone classifier are introduced . the function and application result of the measure and control system are discussed with practical application 本文對以前的測量方法進行分析和比較,從外業(yè)、內業(yè)兩大環(huán)節(jié)入手,利用全站儀的坐標測量功能及自行設計,研制的雙微棱鏡片測桿,提出球形構筑物半徑測算的新方法。
Refer to the impacting - echo technology , we impacted the apex of the steel bar and incepted the reflecting stress ave through the resonator that fixed on the apex of the steel bar , and the value of the consolidating wave speed was calculated based on the time of stress wave transmitted and the length of the steel bar , so , identifying the reflecting signal is the key of the consolidating wave speed method 借鑒于沖擊回波技術,固結波速的測定方法是在鋼筋測桿的出露端施加瞬態(tài)沖擊載荷,由安設在測桿頂端的傳感器接收反射應力波信號,根據應力波的走時和測桿的長度折算固結波速的大小,因此反射信號的識別是固結波速法檢測混凝土強度的技術關鍵。
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、步進電機驅動器,驅動步進電動機,由步進電動機通過傳動機構推動被檢指示表的測桿移動,從而實現測桿的微量進給。
Simultaneously with the micro - displacement started the processe of the grating sensor measuring the displacement and image collection of the system . the grating sensor ( length gauge ) measures the displacement of the dial gauge with surveying rod . it is delivered to the computer with a block k220 in real time and the dial image by ccd camcorder is shown on the computer screen with the image collection card in real time 在實現微量進給的同時,啟動系統(tǒng)的光柵位移測量過程和圖像采集過程,光柵傳感器(長度計)測得指示表測桿的位移量,由計數卡ik220實時傳送給計算機,由ccd攝像頭攝取的表盤圖像經圖像采集卡在計算機屏幕上得以實時顯示,最后通過對指示表指針位移計算處理與光柵傳感器測量的位移量進行比較,得到指示表受檢點的示值誤差。
