关键字：ABB阀门定位器 http://www.abb-positioner.com/ ABB阀门定位器在一般情况下会采用自定义PID控制技术、电源进线端接电解电容和集成芯片配置瓷片电容可以减少干扰且挑选性价比高的芯片。ABB阀门定位器中的单片机接收操作人员通过键盘所设定的信号与反馈回来的阀位实际信号并通过计算出这两个值的差值，再经过控制算法对这个差值的计算会得出一个控制信号值，最后控制信号的值通过输出驱动阀门动作，同时，ABB阀门定位器还可以完成将各类信号液晶显示，故障报警，串口通讯等功能，从而达到预想的控制效果。ABB阀门定位器能够完成这一系列的工作离不开它自身的结构，它主要包含以下三个结构：1.输入机构：输入部分检测从前向通道引入的信号并将其送到比较装置。2.反馈机构：反馈装置检测阀门位置的变化，并把反馈信号传递到前向通道。3.比较机构：比较机构比较设定信号和阀位反馈信号，如果检测到这两个信号之间有不同，就通过算法得到控制信号驱动阀门直至阀门反馈信号与设定信号一致。德科蒙过程控制(武汉)有限公司座机:027-88062221传真:027-88068180邮箱: sales@whdkm.com原文出处：http://www.abb-positioner.com/a/xwdt/134.htmlABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" sandbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C9%3A32776%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&guci=2.2.0.0.2.2.0.0&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=32.0.0&pra=5&wgl=1&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfV0.&dt=1602576775278&bpp=14&bdt=212&idt=238&shv=r20201008&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=6315684765749&frm=23&ife=1&pv=1&ga_vid=515393279.1602576776&ga_sid=1602576776&ga_hid=929799762&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=6&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=17&u_nmime=34&adx=-12245933&ady=-12245933&biw=1332&bih=649&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42530672%2C44729772%2C21065724%2C21067948&oid=3&pvsid=178807684752369&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1030%2C730%2C360&vis=2&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=0&uci=0.aaqcd9o0xnrm&fsb=1&dtd=252" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.aaqcd9o0xnrm" data-load-complete="true"> |
