2.2 RS-232接口电路

　　MAX3221采用单电源供电，电源接人方式简单，内部由1个线性驱动，1个接收器，带±15kVESD保护的双速电荷泵电路组成。可以实现RS-232电平到TTL电平的转换。MAX3221的另一优点是自动掉电功能。当无输入信号时，可通过单片机的控制驱动器和接收器都将关闭，进人很低功耗的待机状态（1μA），达到节能目的。

2.3 RS-485接口电路

　　由于基于差分信号传输的RS-485总线本身具有抗干扰能力强等特点，系统采用RS-485的通讯方式与主控机进行远距离的通讯。要求无论是模拟信号还是RS-232信号通过单片机采集处理后，均可以用RS-485通讯方式进行远传。电路中采用了DC-DC隔离电源供电，并在单片机与RS-485通讯电路之间采用了高速光电耦合进行隔离，从而进一步提高了整个通讯模块系统的抗干扰能力。MSP430F149串口2的TTL电平到RS-485接口电平的转换采用的是芯片75176。通过RS-485总线的方式进行多机通讯时，如果某时刻某个75176的DE端电位
