摘要
应答器传输系统已广泛应用于我国高速铁路和城市轨道交通线路中。互联互通测试是应答器传输系统的重要测试项目,而参考环是应用在互联互通测试中的定标部件。分析了参考环的校准对测试结果的影响;研究了参考环的校准过程和相关的模型及原理;提出了一种可操作的参考环校准方法;进行了验证及校准效果对比评估。实验证明,使用本方法进行校准得到的参考环参数对测量值的修正效果明显。
Balise transmission system has been widely used in Chinese high-speed railways and urban rail transits. Interoperability test is one key testing item of the balise transmission system and reference ring is a calibration component used in the test. A study is made on the influences of the calibration of reference ring on the test’s results, the calibration process of reference ring as well as relevant model and principle. Furthermore, a workable calibration method of reference ring is put forward, the verification of the calibration method is conducted, and a comparative evaluation of the results is also made. The test shows that the effect is obvious to adjust the reference ring’s parameters using the measured values obtained by this method.
