摘要 随着列车运行速度的不断提高,以及车-地信息量的越来越大,仅依靠轨道电路传输信息至车载设备的住院方式,已经不能满足列车安全、高速行驶的要求。郑—西客专CTCS-3(CTCS-2)列控系统,通过设在两条钢轨固定点的有源应答器和无源应答器向列控车载设备传递大量的固定信息和可变信息。这种方式与轨道电路相比,不仅信息量大,而且安全可靠。应答器作为信息传递的主要元件,对其作用、性能的分析,对于正确使用应答器,保证列车运行安全至关重要。所以,应答器在高速铁路中被普遍应用。 With the continuous improvement of train speed,and more and more train to ground information, the traditional way of transmitting the information only from the track circuit to on-board equipment can not meet the requirement of the safety and the high-speed of the train. Train control system of Zheng-West passenger dedicated line CTCS-3 (CTCS-2), through the active and passive transponder which were on fixed point of two steel tracks, delivered a lot of settled information and variable information to the train control board. Compared with the track circuit, this system was not only informative, but also safe and reliable. Transponder as the main component of the information transmission, it was important to analysis its function and performance. So that it can be corretly used to ensure the train security. Therefore, the transponder was widely used in the high-speed railway.
