The invention discloses an aircraft control surface state real-time sensing method and system. The system comprises an embedded pressure sensor, an embedded processor, a signal transmission module and an angle comparison module. The embedded pressure sensors are made of silicon wafers and are arranged at specific positions on the front edge, the upper surface and the lower surface of the aircraft control surface to monitor pressure signals on the surface of the control surface in real time. And according to the surface dynamic pressure information, the real airflow angle and the surface flow condition of the control surface are solved and are compared with a control surface control instruction input by a flight control system, and whether the angle of the control surface reaches a specified position and whether flow separation occurs on the control surface are judged. According to the embedded pressure measurement aircraft control surface state real-time sensing system and method, a beneficial monitoring means and a feedback method are provided for control surface control and flow control in the flight process of an aircraft, and aircraft safety accidents caused by control surface jamming or failure are avoided.
