铁路区间信号系统测试评估平台——自动闭塞移频信号的数据采集及验证

Testing and Assessment Platform for Railway Section Signal Systems --Data Acquisition and Validation for Frequency-shift Modulated Signal in Automatic Block Systems

铁路区间信号系统测试评估平台中数据采集和验证子系统研究移频信号的数据采集、A/D转换和信号显示,移频信号的处理是对被测系统发送和接收的移频信号的载频和调制低频鉴频鉴幅,进行验证,为测试评估平台对被测系统的功能、可靠性和安全性评估作必要的数据准备.

The data acquisition and validation subsystem of testing and assessment platform for railway block signaling system (TAPRBSS) is designed to implement data acquisition, A/D transformation and FSM signal displaying. To process frequency-shift signal is to detect and validate frequencies and amplitudes of carriers and modulated signals, which are sent out and received by block systems under test. In this way, necessary data are prepared for TAPRBSS to test and assess the function, reliability and safety of block systems.
