Currently , large - scale distributed systems generally use three - tier client / server computing model based on middelware . in this pattern , developers could concentrate on business logic programming , and let those numerous complexions such as network programming , or distributed transaction maintaining , etc . be implemented by the lower middleware 在這種計算模式下,系統的復雜應用需求集中體現在位于服務器端的業務邏輯功能實現上;基于中間件技術,分布式系統的開發人員能夠擺脫傳統的網絡編程以及維護分布事務完整性等的繁瑣局面,直接針對業務邏輯功能進行實現。
It effectively separate logic programming from interface design . moreover , the system combines web services to struts frame . in realization of web services , the system make use of axis which is most extensible and completely opened soap engine 在系統設計上,采用了基于mvc模式的struts框架,有效地實現了界面設計和邏輯編程的分離;并把webservices應用到struts框架中,實現服務流程自動化;在web服務實現上,采用了擴展性最強、完全開放和可插入體系結構的引擎axis 。
The dcs of i / a series is regarded as main reference object , and the control is separated from model . and the configuration of control is operatised at administration system , not to be added into model , not to build control sound code also . therefore it realizes on - line adjusting , real - time control and so on . users configurate by filling table . they only define i / o condition , fill certain operation variable , and name logic variable . the software offers a friendly user ' s interface , so personnel can compile and modify the control and logic program , change the value of logic and control variable conveniently , attach themselves to run , debug and control the system , not need to know the programs deeply . so the configuration software offer a flat that control engineers can attend to control loop , not to give their attention to the complicated program 在本課題中,采用填表的方式進行控制組態,用戶只需定義i / o條件、填寫具體的運算變量名即可。本軟件為建模人員提供了一個友好的用戶界面,使建模人員在建模時不必對模塊內部的控制、邏輯程序有很深的了解就可以方便的對其進行編寫和修改,實時改變各邏輯和控制變量在數據庫里的值,參與運行和調試,從而實現對系統的控制。因此,本組態軟件提供的這樣一個平臺,讓控制工程師能集中精力于控制回路的構成,而不必拘泥于一些具體而煩瑣的程序操作。
With the development of science , embedded system has been widely used in the field of industrial control and intelligent appliance with increasing complication of control logic and function . as compared with the simple control logic program of the earlier embedded system , modern embedded system is inclient to integrated operation system , which makes embedded system more and more important 隨著科學技術的不斷發展,嵌入式系統在工業控制和智能家電領域得到了廣泛的應用,同時控制邏輯和功能也變得越來越復雜,相對于早期嵌入式系統所采用的簡單的控制邏輯程序,現代嵌入式系統越來越傾向于使用完整的操作系統,這就使得嵌入式操作系統在嵌入式系統領域變得越來越重要。
