摘要本文铁路应答器检测系统是采用检测仪表对铁路应答器进行检测的系统。相比于传统铁路采用的轨道电路,应答器不存在断轨,异物阻碍,电路异常断线等问题,它通过地面设备和车载设备实现了地车之间的实时信息交换,以及列车当前信息与列控中心的监控与防护,使得列控中心能更高效地进行列车定位和速度防护,大大提升了列车行驶过程中的安全性与可靠性。

本文对应答器检测系统中的检测仪表进行研究与设计。通过对检测仪表的硬件设计和软件开发,设计出能够检测铁路应答器的安装是否符合规范以及能否正常工作的检测仪表。硬件采用89C51型单片机作为微处理器,A/D转换器选用ADC0804。软件对DBPL信号的测量采用测量频率法。通过软硬件的结合,实现对铁路应答器检测系统的设计。69870

Design of Railway transponder detection system

Abstract The design of the railway system is the use of a transponder detection detection instrument for detecting the transponder railway system. Compared to conventional rail track circuit using the transponder does not exist off the rail, foreign body obstruction, abnormal circuit disconnection and other issues, it is by ground equipment and on-board equipment to achieve a real-time information exchange between vehicles, as well as current information and train monitoring and protection of train control center, so that the train control center can more efficiently locate and train speed protection, greatly enhance the process of moving train safety and reliability.

In this paper, the transponder detection system instrumentation research and design. Through the instrumentation hardware design and software development, rail design capable of detecting transponder installation meets the specifications and can work properly instrumentation. Hardware using 89C51 microcontroller as a microprocessor, A / D converter used ADC0804. Software for measuring DBPL signal by measuring the frequency method. By combining hardware and software, to achieve the railway transponder detection system design.

The papers have 12 figures, 1 table and 35 references.
