摘要
应答器作为车-地间信息传输的重要方式之一,在列车运行控制系统中得到了广泛的应用,欧洲应答器也因其具有诸多的优点而逐渐成为中国列车控制系统CTCS所主要借鉴的技术规范。文章在介绍了应答器处理器工作原理的基础之上,重点分析了欧洲应答器报文的译码策略,并尝试利用现场可编程门阵列FPGA器件对译码策略进行了模拟实现,最后在QuartusⅡ平台上应用硬件描述语言VHDL对设计进行了仿真分析,仿真结果达到了预期目的。
As one of the most important methods to transmit information between the train and the trail, balise is widely used in the control system of automatic train operation. And EUROBALISE is becoming the most primary technical specification of CTCS because of its advantages. This article first introduced the working theory of the BALISE BTM. Then it tried to show the way of simulating the decoding strategy based on Field Programmable Gate Array (FPGA). Finally, the article made some emulation analysis on the platform of Quartus II by using hardware description language VHDL. The result of emulation showed the expected purpose.
