摘要
介绍一套高速铁路轨道信号模拟系统,讨论了系统的硬件和软件设计方法。系统以TMS320C6722浮点DSP为数据处理核心,ARM协处理器为控制核心,能够模拟自主开发的、适合中国高速铁路的改进型数字编码和正交化FSK轨道信号的发送和解调过程。
The design develops a simulation system of track signals. This paper analyzes the design method of the system＇s hardware and software. TMS320C6722 Floating-point DSP is applied as data processing core,ARM is applied as control core, and the system simulates the transmission and demodulation of improved digital coding and orthogonal FSK track signals, which is developed independently and suitable for Chinese high-speed railway.
