Besides the design of the hardware construction for shape meter, the software system written in visual basic 6.0 is also developed . the real-time data acquisition and conversion system worked in interrupt mode is accomplished by means of loading dynamic linkage library of pcl-812pg enhanced multi-lab card . the converted data processing will be operated then, for example, scale operation, comparison, graphic display, data storage, etc . the adjusting values for the shape control are also calculated in it 本文在參考大量帶材標(biāo)準(zhǔn)板形、軋制初始量設(shè)定、調(diào)節(jié)量計算研究的基礎(chǔ)上,確定了標(biāo)準(zhǔn)板形模型、設(shè)定模型、調(diào)節(jié)控制模型等數(shù)學(xué)模型;并給出了其相應(yīng)的算法;完成了板形儀計算機控制系統(tǒng)的硬件設(shè)計,并在此基礎(chǔ)上,應(yīng)用高級開發(fā)語言visualbasic6.0,通過加載pcl-812pg多功能數(shù)據(jù)采集卡的驅(qū)動程序后,調(diào)用動態(tài)鏈接庫(dll)中的函數(shù)的方法,完成了信號中斷方式下的實時數(shù)據(jù)采集,采集的數(shù)據(jù)經(jīng)計算機作標(biāo)度變換、對比、圖形顯示、存儲等處理,并提供了用于板形閉環(huán)控制的調(diào)節(jié)量。
