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 通過實際運行表明,基于modbus協議的現場總線儀表的穩定性、實時性以及精度都比傳統儀表優越;基于modbus現場總線儀表的控制系統在容錯處理、數據交換、系統管理、抗環境干擾等方面都比傳統儀表組成的系統功能強。
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 通過實際運行表明,基于can協議的現場總線儀表的穩定性、實時性以及精度都比傳統儀表優越:基于can現場總線儀表的監控系統在容錯處理、數據交換、系統管理、抗環境干擾等方面都比傳統儀表組成的系統功能強。
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 在對配件靜態數據的分析整理及實施技術的研究中,基于重構后的配件數據,建立了科學合理的分類原則和編碼體系,解決了配件數據的規范化和標準化問題,采用數據庫編程技術,設計了數據準備、轉換和檢查程序,實現了對數據準確性和重碼率的控制。
