Research and Development of the monitor system of shifting frequency signals

The monitor system of shifting frequency signals is an engineering control and test system.By research and development,real-time monitor to railroad shifting frequency signals is realized.The asynchronous movement mechanism of interface demonstration,data gathering and data storage is used in the system,therefore it has characteristics of little memory consumption,quick response speed and good real-time network transmission.This system structure is introduced and some key problems are solved for the system realization.
