Abstract

The invention relates to an embedded control surface gap and skewness automatic detection method and equipment, an upper computer controls an electric cylinder to apply continuous loading force to a control surface through an RS232 serial port, an embedded controller acquires a force sensor and a gap displacement sensor in real time, and the force sensor and the gap displacement sensor are sent to the upper computer through an RS422 serial port after low-pass filtering. A force-displacement curve is drawn in real time after analysis of an upper computer, a control surface gap value is calculated, the upper computer sends a control surface deflection control instruction to an onboard maintenance assembly through an RS422 serial port and drives a control surface to deflect, and an embedded controller collects skewness displacement sensor signals in real time and sends the skewness displacement sensor signals to the upper computer through the RS422 serial port. The control surface skewness value is analyzed and calculated by the upper computer, and the motor power supply supplies power to the electric cylinder. According to the method, equipment self-detection, automatic test, automatic test data acquisition and interpretation and high control surface skewness displacement measurement precision of control surface gap displacement measurement are realized, and the reliability, maintainability and safety are good.
