Ak series intelligent pressure transmitter which is universal intelligent series transmitter , it introduced advanced production technology from america and japan adopts the world leading technique , pass through strict quality control . this kind of transmitter is searched and developed independently by our company that is pressure detect transmit unit in the industrial automation control system . it measures fluid pressure in the industry process and converts it into 420 ma dc signal output ; at the same time , it may be remote parameter setup , remote control , self - diagnosis by field hart protocol 是引进美国和日本的先进生产工艺,采用世界领先技术,经过严格的品质管理,由我公司自行研制和开发的通用智能型系列变送器,是工业自动化控制系统的压力检测变送单元,它测量工业过程流体压力,将其转化成4ma 20ma dc信号输出,同时通过现场hart协议可进行远程参数设定远程控制自诊断等功能。
In this paper , the upper - class intelligent control scheme is adopted according to the characteristics of tobacco re - dryer and the present control condition in order to solve the problem that the output tobacco moisture can ? keep stable . that is , to keep the old every pid control link , to add the upper - class computer so that sets up the upper - class intelligent control system that consists of the description management sub - system , the fuzzy compensation on line sub - system and the self - learning system . the following are control procedure : first of all , a series of output values of description can be obtained by the forward inference of basic controller on the basis of the information of input tobacco , then , these output values can be adjusted by the fuzzy compensation controller with inquiring the fuzzy control - list on line in the light of the output tobacco moisture error 本文针对烤机的工艺特点和目前控制现状,提出用上位智能控制的方法解决烤机目前存在的问题,即在保留原有各段pid控制的基础上,增加上位计算机,建立起由配方管理子系统、模糊在线修正子系统和自学习系统组成的上位计算机监控、决策的智能控制系统;控制过程为:基本配方控制器根据来料信息正向推理提供烟叶复烤机各段参数设定值的基值;模糊补偿控制器根据烟叶水分偏差在线查询模糊控制表提供相应参数设定值的修正值,实现烟叶复烤机参数的在线修正;学习环节的引入实现烟叶配方的在线优化。
First , the complete machine is controlled by the germany siemens programmable local controller ( plc ) . secondly , mitsubishi e - 540 variable frequency main shaft stepless speed regulation function is provided . thirdly , siemens chinese td - 200 text panel indicator is used for parameter set . the winding number , tension and velocity can be modifies at real time . in addition , the complete machine has high degree of automation . the work of filling in workpiece , clamping , moving workpiece to the winding position , winding , trimming and holding line head etc can be finished for one time 参数设定采用西门子中文td - 200文本面板显示器,可对匝数绕线张力、绕线速度参数进行实时修改。整机自动化程度高。从工件放入工件夹紧送工件至绕线位绕线剪线并夹住线头… …一次性完成。
Lastly , the detailed design procedure is brought forward , which consists of the design of database , the parameterized design and matching of locating box , design of roughcast and its fixing in the locating box , design and management of stuffing , communications between all subsystems , intelligent positioning of locating bolts and management of ips 接着,对信息处理子系统进行了详细设计,包括数据库的设计、寻位箱参数化设计及其配置、毛坯设计及其在寻位箱中的定位安装、填料设计与管理及其关键填料参数设定、寻位元件的智能布置、系统间通讯和系统管理。
The upper computer system software was developed with vb and composed of five modules , such as setting of parameters , real - time monitoring and collecting data , reproduction of history data and help module . each module has certain function and could visit to other modules 上位机系统软件采用可视化编程语言visualbasic6 . 0来开发,主要由参数设定模块、通信模块、数据实时采集监控模块、历史数据显示模块和帮助模块组成;每个模块独立完成一定功能,各模块之间可以相互访问。
