ID:280979 · 发表于 2018-2-24 12:22

【上位机界面】（提供源代码）

一、尺寸：长233.7mmX宽182.7mmX高25mm
二、主要芯片：STC12C60S2支持双串口（支持51系列DIP40封装单片机）
三、工作电压：直流24伏供电（另有12V供电）
四、串口1（COM1）下载程序，（RS485口使用单机机内部串口2均可与上位机通讯）
五、输出供电采用延时通电电路（1至10秒可调）
功能：当输出接有被控制设备，避免单片机初次上电（或下载程序）时，输出设备误动作。此功能在实际应用中起到很大作用
五、特点：
         1、具有电源指示。
         2、三十路带光电隔离输出控制继电器。
            3、标准的11.0592M晶振。（便于设置串口波特率）
         4、具有上电复位和手动复位。
         5、支持51系列DIP40封装单片机。
   5、输出三十路继电器的供电采用延时供电（避免被控制设备误动作）
         6、输出三十路具有LED指示。
            7、三十路12V继电器控制，控制设备。
         8、可控制交流220V/10A一下设备。
         9、具有RS232和RS485通信功能(可以同时和上位机通信)。
         10、单片机无加密，可插拔更换，可随意更改程序。
