By running of instrument , it is proved that stability and real time and precision of instrument based on modbus fieldbus are better than traditional instrument . the error - delaing and data - switching and system - managing and anti - jamming of control system based on modbus fieldbus instruments are better than the system based on traditional instruments 通過(guò)實(shí)際運(yùn)行表明,基于modbus協(xié)議的現(xiàn)場(chǎng)總線儀表的穩(wěn)定性、實(shí)時(shí)性以及精度都比傳統(tǒng)儀表優(yōu)越;基于modbus現(xiàn)場(chǎng)總線儀表的控制系統(tǒng)在容錯(cuò)處理、數(shù)據(jù)交換、系統(tǒng)管理、抗環(huán)境干擾等方面都比傳統(tǒng)儀表組成的系統(tǒng)功能強(qiáng)。
By running of instrument , it is proved that stability and real - time and precision of instrument based on can fieldbus are better than traditional instrument . the error - delaying and data - switching and system - managing and anti - jamming of control system based on can fieldbus instruments are better than the system based on traditional instruments 通過(guò)實(shí)際運(yùn)行表明,基于can協(xié)議的現(xiàn)場(chǎng)總線儀表的穩(wěn)定性、實(shí)時(shí)性以及精度都比傳統(tǒng)儀表優(yōu)越:基于can現(xiàn)場(chǎng)總線儀表的監(jiān)控系統(tǒng)在容錯(cuò)處理、數(shù)據(jù)交換、系統(tǒng)管理、抗環(huán)境干擾等方面都比傳統(tǒng)儀表組成的系統(tǒng)功能強(qiáng)。
In the session of the analysis and coordination of those static data of fittings , on the basis of the reformed data of fittings , the paper establishes both a scientific classifying principle and also a rational coding system , which resolved the problem of the fittings - data - standardization . in order to control the actuality and the rate of overlapped codes , the paper has designed data - preparation programs and data - switch programs and data - checking ones through database programming technologies 在對(duì)配件靜態(tài)數(shù)據(jù)的分析整理及實(shí)施技術(shù)的研究中,基于重構(gòu)后的配件數(shù)據(jù),建立了科學(xué)合理的分類原則和編碼體系,解決了配件數(shù)據(jù)的規(guī)范化和標(biāo)準(zhǔn)化問(wèn)題,采用數(shù)據(jù)庫(kù)編程技術(shù),設(shè)計(jì)了數(shù)據(jù)準(zhǔn)備、轉(zhuǎn)換和檢查程序,實(shí)現(xiàn)了對(duì)數(shù)據(jù)準(zhǔn)確性和重碼率的控制。
