铁路车辆是靠压缩的流动空气作为制动动力源及控制信号源，所以高原特殊环境下铁路车辆制动性能可能发生变化。

The vehicle compressed fluxion air is used to conduct the control signal source and brake, so in special environment of plateau the vehicle system brake performance may variety.

本设计结合这两项技术，并利用单片机灵活的控制技术，开发了一种新的信号源：任意波形发生器(AWG)。

With the two technologies and the flexible control ability of MCU, a new digital signal source, Arbitrary Waveform Generator (AWG), has been developed.
