摘要
基于现有UM71无绝缘轨道电路的传输通道,讨论了各种传输方案,提出了一种采用模拟调频方式的32位数字编码轨道电路,选用TMS320C32作为CPU,设计了发送和接收子系统,最后给出了室内仿真试验及其结果.
This paper presents a kind of 32_bit digital coding track circuit after analyzing modulation modes based on an existing transmission channel of UM71 track circuit. Then its prototypes of transmitter and receiver are implemented with TMS320C32 as CPU. Finally, the simulation method and its results are also given.
