High-speed rail sand table train control system

Provided is a high-speed rail sand table train control system. The high-speed rail sand table train control system comprises a simulated track and a simulated train. The simulated track comprises two or more track sections, control devices arranged in the track sections and ground signal machines; the control devices have the same structures, each control device comprises a frequency-shift signal transmitter and a frequency-shift signal receiver which are arranged at the two ends of each track section respectively, an input end of the frequency-shift receiver is connected with the simulated track through a transmission line, an output end of the frequency-shift receiver is connected with the frequency-shift signal transmitter of a latter track section through another transmission line, and a controlling end is connected with the ground signal machine in the same track section; the simulated train comprises an inductance coil, a small-signal amplifying circuit, a frequency-shift demodulator, a train signal machine and a train traction system. According to the high-speed rail sand table train control system, the frequency-shift transmitter is adopted to send information to a rail surface, the frequency-shift receiver is used for demodulating the information and controlling the ground signal machines, the simulated train can receive frequency-shift information from the rail surface and control the train signal machine lighting and the running speed of the train, therefore, the real simulation of a railway site is achieved.
