ID:280979 · 發(fā)表于 2018-2-24 12:22

【上位機界面】（提供源代碼）

一、尺寸：長233.7mmX寬182.7mmX高25mm
二、主要芯片：STC12C60S2支持雙串口（支持51系列DIP40封裝單片機）
三、工作電壓：直流24伏供電（另有12V供電）
四、串口1（COM1）下載程序，（RS485口使用單機機內(nèi)部串口2均可與上位機通訊）
五、輸出供電采用延時通電電路（1至10秒可調(diào)）
功能：當輸出接有被控制設(shè)備，避免單片機初次上電（或下載程序）時，輸出設(shè)備誤動作。此功能在實際應(yīng)用中起到很大作用
五、特點：
         1、具有電源指示。
         2、三十路帶光電隔離輸出控制繼電器。
            3、標準的11.0592M晶振。（便于設(shè)置串口波特率）
         4、具有上電復(fù)位和手動復(fù)位。
         5、支持51系列DIP40封裝單片機。
   5、輸出三十路繼電器的供電采用延時供電（避免被控制設(shè)備誤動作）
         6、輸出三十路具有LED指示。
            7、三十路12V繼電器控制，控制設(shè)備。
         8、可控制交流220V/10A一下設(shè)備。
         9、具有RS232和RS485通信功能(可以同時和上位機通信)。
         10、單片機無加密，可插拔更換，可隨意更改程序。
