analysis of asphalt spreader's automatic leveling system simulated by computer 423瀝青混凝土攤鋪機(jī)上的應(yīng)用
at first, the author analyzed some chief factors such as light beam drift and atmospheric turbulence that affect the precision of the laser collimation in brief . then, the author studied the plan of the laser collimation generating nondiffracting beam and automatic level system with high precision . at last, the author completed the measurement of the straightness guideway by using ccd ( charge coupled device ) as the receiver and computer imaging processing 文章首先簡(jiǎn)要地分析了激光自身漂移、大氣湍流等影響激光準(zhǔn)直精度的主要因素,然后對(duì)系統(tǒng)的激光準(zhǔn)直方案進(jìn)行論證,并確定了無(wú)衍射光束的生成方案、高精度自動(dòng)安平系統(tǒng)的結(jié)構(gòu)方案,最后以ccd為接收器件,通過(guò)計(jì)算機(jī)圖像處理,完成對(duì)軌道直線性的測(cè)量。
management information system is developed with vb6.0, and used activex data objects technology c onnecting access database . this project strides over many subject such as electrocircuit, sensor, singlechip, embed system, computer communication, and software engineering, so this reading rneter system is a high automatic level system . the system successfully integrates auto-reading and manual-reading, and realizes automatic managing data, which not only convenience manager, hut alse convenience user 本系統(tǒng)中,電能表的微處理器是在microchip公司提供的pic系列單片機(jī),其匯編程序是在mplab編譯環(huán)境下開發(fā)和調(diào)試的;手抄器是land公司的ht-2800型掌上電腦,其應(yīng)用程序是在該公司提供的模擬仿真平臺(tái)上,使用htbase語(yǔ)言設(shè)計(jì)、開發(fā);上位機(jī)系統(tǒng)的開發(fā)是使用vb6.0,并采用activexdataobjects技術(shù)通過(guò)ado對(duì)象訪問(wèn)aceess數(shù)據(jù)庫(kù),從而實(shí)現(xiàn)數(shù)據(jù)管理的目的。
