中文摘要：
应答器传输模块高速通过地面应答器时的接收性能测试是我国目前客运专线列控系统运用中亟需解决的问题。针对该问题，本文提出一种面向应答器传输模块测试的上行链路信号模拟器。首先分析应答器传输模块高速过点时的工作机理，深入研究车速对应答器传输模块高速过点时接收到的上行链路信号的幅度、频率和相位的影响，推导出应答器传输模块高速过点时实际接收到的上行链路信号表达式，然后提出基于自动测试系统和虚拟仪器设计方法的上行链路信号模拟器的软硬件实现方案。实际应用和测试表明，上行链路信号模拟器产生的信号和理论分析相符，可以有效地实现对应答器传输模块接收性能的测试。
英文摘要：
At present, testing the receiving capability of Balise Transmission Modules （BTM） passing ground balises at high speeds remains an urgent problem to be solved in the Train Control Systems （CTCS） of passenger dedicated lines in China. The Uplink-Signal simulator is used in the BTM test. The paper explains the operation principle of the BTM which passes the ground balise at a high speed. The influence of the train speed on the amplitude, frequency and phase of the Uplink-Signal received by BTM is analyzed. The expression of the received uplink-signal is deduced. Then, the software and hardware realization scheme based on the design method of the automatic test system and virtual instrument is proposed. Trial tests show that the signal generated by the uplink-signal simulator conforms to the theoretical analysis and the BTM receiving capability is tested successfully.
