TRCON是一種現(xiàn)代化的可編程邏輯與過程控制器,可以提供高水土的系統(tǒng)容錯能力的控制器3下面說明袞錯是怎么二回事并列患TRICON系統(tǒng)的主要特性。.
1.1.1什么是容錯?
容錯是TRICON系統(tǒng)的最為重要的能力,它是指對瞬態(tài)的和穩(wěn)態(tài)的出錯情況的探查發(fā)現(xiàn)的能力以及采取適當?shù)南鄳?yīng)的在線措施的能力。具有容錯能力時,控制器及其控制的過程的安全性得以增強,利用率得以提高。
TRICON通過三重組合式冗余結(jié)構(gòu)(TMR)而給出其容錯能力。此系統(tǒng)由三個完全相同的系統(tǒng)支路組成電源模件除外,該模件是雙重冗余的)。每個系統(tǒng)支路獨立地執(zhí)行控制程序,并與其它兩個支路并行工作。硬件表決機制則對所有來自區(qū)域場的數(shù)字式翰入和輸出進行考核和驗定。模擬輸入則經(jīng)受中值選擇處理過程。
因為每一個支路都是和其它兩個隔離的,任一支路內(nèi)的任何一個單點失效都不會傳遞給其它兩支。如果在一支內(nèi)有硬件故障發(fā)生,該失效的一支就能被其它兩支所補償。所以修理工作,包括拆卸和更換失效的支路內(nèi)的失效模件都可以在TRICON在線情況下進行,不使過程中斷。系統(tǒng)能自行重新配置而進行充分的TMR運作。
對于各個支路、各模件和各功電路的廣泛的診斷工作能夠及時地探查到運行中的故障,并用指示器或警報作出報告。診斷還可以把有關(guān)故障的信息存儲在系統(tǒng)變量內(nèi)。在發(fā)現(xiàn)有故障時,操作者可以利用診斷信息以修改控制動作,或者指導(dǎo)其維護過程。
從用戶的觀點看,使用是簡單的,因為此三重系統(tǒng)工作起來和一個控制系統(tǒng)一樣。用戶連接感應(yīng)器和作動器于單一的接線端上,并且用一組應(yīng)用邏輯為TRICON編程。其余的事都由TRICON自行經(jīng)管。

TRCON is a modern programmable logic and process controller that can provide a high system fault tolerance controller 3 below explains how two things are side-by-side suffering from the main features of TRICON systems. .
1.1.1 What is Fault Tolerance?
Fault tolerance is the most important capability of the TRICON system, which refers to the ability to detect transient and steady-state error situations and take appropriate online actions. With fault tolerance, the safety and utilization of the controller and the processes it controls are enhanced.
TRICON gives its fault tolerance through the triple combined redundant structure (TMR). This system consists of three identical system branches, except for the power module, which is doubly redundant). Each system branch executes the control program independently and works in parallel with the other two branches. The hardware voting mechanism checks and validates all digital inputs and outputs from the field. Analog inputs undergo a median selection process.
Because each branch is isolated from the other two, any single point failure in any branch is not transmitted to the other two branches. If a hardware failure occurs on one side, that failure can be compensated for by the other two. As a result, repair work, including removal and replacement of failed modules in failed branches, can be carried out while TRICON is online without interrupting the process. The system can reconfigure itself for full TMR operation.
Extensive diagnostic work for each branch, each module and each power circuit can detect faults in operation in time and report them with indicators or alarms. Diagnostics can also store information about faults in system variables. When a fault is found, the operator can use the diagnostic information to modify the control action or to guide its maintenance process.
From the user's point of view, use is simple because this triple system works like a control system. Users connect sensors and actuators to a single terminal and program TRICON with a set of application logic. The rest is handled by TRICON itself.
