Synchronous transmitting observe and control method and system of train pneumatic performance simulation test apparatus

The invention relates to a synchronously transmitting measurement and control method and system for aerodynamic performance simulation test device of train. The method comprises: using an assistant measurement and control computer for setting load capacity of ejection force, outputting a control signal controlled by a total console through a programmable controller which indirectly or directly controls synchronous transmission of a train model through an electric device control cabinet; triggering synchronous measurement and control by the train model, starting a measurement system for collecting measurement data. The measurement system comprises a train-carried data collection system and a ground data collection system. The invention is capable of measuring and controlling the whole process comprising ejection force loading synchronous transmission and synchronous sampling of train model starting performance simulation test, realizing synchronous transmission, dynamic measurement and synchronous measurement
