摘　　要：设计了一种由信号输入电路、单片机控制电路、输出电路、执行电路、报警及电源电路等构成的风源净化控制器。信号控制电路与机车电器回路完全隔离,提高了系统抗干扰能力,同时控制程序固化在微处理芯片中,不需要通过电位器来模拟整定,提高了系统的时间精度及可靠性。The air purifying controller is constructed by the signal input circuit, MCU control circuit, the output circuit, the implementation circuit, alarm and power supply circuits and other components. Signal control circuit with locomotive electrical circuit completely isolated, to improve the anti-jamming capability. While program flash in the micro-processing chip, do not need to sim- ulate the potentiometer tuning, improve time accuracy and reliability of the system.
