Aircraft cabin pressure control semi-physical simulation test system and test method

The invention belongs to the technical field of aviation cockpit pressure control, and particularly relates to an aviation cockpit pressure control semi-physical simulation test system and a test method. The test system comprises a man-machine interaction computer, a simulation computer, an interface device, a program control gas source A, a program control gas source B and a visual system. The simulation computer is at least provided with an atmospheric altitude pressure model, a cabin air supply model, an exhaust valve model and a cabin model. Each model respectively constructs a corresponding simulation scene; the simulation computer sends the aircraft flight state information sent by the interaction computer and the state and fault information sent by the cabin pressure controller to the visual system for display through the interface device. A computer is adopted for simulation, the range of model parameters is very wide, the flexibility is very high, the power consumption is very low, the construction a
