IC693CBL311---IC693CBL311

IC693CBL311---IC693CBL311轉(zhuǎn)速監(jiān)控裝置是水輪發(fā)電機(jī)組重要的自動(dòng)化裝置，本文根據(jù)小型水電站的特點(diǎn)，提出了在控制機(jī)組運(yùn)行的PLC上增加部分硬件，實(shí)現(xiàn)轉(zhuǎn)速監(jiān)控功能的方法，該方法既解決了測(cè)速裝置的可靠性問題，又降低了系統(tǒng)的成本，是一種較為理想的方案。 
1系統(tǒng)硬件構(gòu)成 
系統(tǒng)硬件是利用控制機(jī)組運(yùn)行PLC的8個(gè)晶體管輸出點(diǎn)和一個(gè)高速輸入點(diǎn)，增加LED的譯碼和驅(qū)動(dòng)電路，組成轉(zhuǎn)速監(jiān)控裝置的硬件系統(tǒng)。

系統(tǒng)由轉(zhuǎn)速信號(hào)檢測(cè)單元、PLC（三菱FX2N系列）和LED速度顯示電路三部分組成(如圖1所示)。其中轉(zhuǎn)速信號(hào)檢測(cè)單元由光電碼盤組成，光電碼盤將機(jī)組轉(zhuǎn)速轉(zhuǎn)換成電脈沖信號(hào)，輸入到PLC的高速輸入端（如：X0），PLC程序按單位時(shí)間內(nèi)脈沖數(shù)計(jì)算發(fā)電機(jī)的實(shí)際轉(zhuǎn)速，并顯示在LED數(shù)碼顯示器上。
