轨道车车载无线通信受话音量自动控制的实现

Realization of Automatically Controlling Volume of Radio in Heavy Railcar

针对铁路轨道车司机工作环境噪声大 ,导致了司机听不清 ,甚至根本听不到车载无线电台发出的语音信号这一问题 ,根据模糊控制理论 ,设计了一种用单片机实现的模糊自适应控制语音音量系统 实验表明该系统结构简单 ,易于实现 ,安全可靠 ,进一步提高了铁路轨道车行车。

Owning to the loud noisy of working environment, the heavy railcar driver is unable to receive the sound of the radio in the heavy railcar. To improve receiving effect of the tune, the paper presents a new method of automatically controlling the volume with fuzzy control theory. Design of hardware and software about the control system is analyzed in detail. It has been testified that the structure is simple and reliable, thus farther ensuring safety and reliability traveling course for heavy railcar.
