One kind of the City fast-track vehicle control system and method for network control system

City in one kind of fast-track vehicle control system and a control method for changing network system, after obtaining the catenary high voltage AC or DC input signal by a pantograph, with the AC fed directly to a DC electronic voltage transformer, by the electronic AC and DC voltage transformer after processing, or sent to a DC to AC analog locomotive related equipment, but also the AC or DC locomotive switch sends a signal to associated equipment; power supply voltage as a detection standard and the grid the voltage value of the unique signal. The control system includes a high pressure portion and a control header portion of the chassis, high head portion after the resistor divider from the DC high voltage 1.5kV or 25kV AC power supply voltage becomes suitable weak electrical signal may be processed; and then via the control input chassis sampled signal transmission to the analog output circuit AC or DC analog output circuit to output an analog manner; signal outputted after amplification and transmission to the train after boost related equipment.
