为适应我国高速列车自动控制系统发展的需要,提出采用双CPU加FPGA的系统设计方案,实现移频信号发送。在保证移频信号高相位精度的前提下,实现系统的自动多载频信号切换和实时故障检测。
In order to meet the needs of the development of high-speed train automatic control system in our country, a dual-CPU plus FPGA system design scheme is proposed to realize frequency-shift signal transmission. Under the precondition of ensuring the high phase accuracy of the frequency shift signal, the system can realize the automatic multi-carrier frequency signal switching and real-time fault detection.
