Abstract : this article retrospects the development of sequence control system in thermal power plants at home and abroad ， especially introduces the three developmental stages of sequence control system in china over the past 35 years ， i. e. ： 1. starting stage ； 2. the second stage with programmable logic controller ( plc ) as core hardwares ； and 3. the third stage with sequence control systems of main and auxiliary equipment incorporated into the distributed control system ( dcs ) and with field bus control system ( fcs ) got involved. this article also appraises the features of sequence control system composed of different configurations and looks forward to the developmental tendency of this system for the next century
文摘:回顧國內、外火電廠順序控制系統的發展，特別介紹35a來我國順序控制系統經歷的起步階段、以程序控制器（ plc ）為核心硬體的中期階段和主、輔機順序控制系統融入分散控制系統（ dcs ）階段、現場總線控制系統（ fcs ）介入階段，並對由不同形式組成的順序控制系統的特點進行評價，展望下一世紀該系統的發展趨勢。 -
In data sampling circuit, high - speed, complex programmable logic device cpld technique is used. high - speed double - port ram, control sampling time sequence logic, cpu interfaces and bus circuit are implemented in cpld. sampling speed is up to 80mhz, sampling depth is ik - byte, and cpld can fulfill the requirement of the software arithmetic to sampling
在數據採集電路中採用了高速復雜可編程邏輯器件cpld技術，晶元內設計有高速雙埠ram 、控制采樣時序邏輯及cpu介面、總線等電路，采樣速率高達80mhz ，采樣深度1k位元組，很好地解決了超聲波微位移傳感器軟體演算法對采樣的要求，並可實現在線升級，大大提高了系統的整體性能。 -
