Embodiment example

[0027]A method of embedded rudder face gap and amplifier automatic detection method and device in actual case are illustrated by a steering rudder gap and amplifier. Before performing the gap detection of the flake rudder, first, according tofigure 1 After all electrical connections are completed, open the "Motor Power" switch and "sensor power" switch to start the host computer. The upper machine sends a "self-test" instruction to the embedded controller. After the embedded controller completes the self-test, the self-test results are reported, the upper machine pops the text window, if the text content is "self-test success", it indicates that the equipment is self-test, can Continue test, if the text content is "CH X channel abnormality" X represents the corresponding channel number, the self-test failure is required. Then, the electric cylinder telescopia is then controlled by the upper machine, and the stroke of the electric cylinder is adjusted to the -2mm ~ + 2 mm scale posit...

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.

Description

Technical field[0001]The present invention belongs to the field of avionics technology, especially for rudder gaps and amplifier detection equipment for aircraft flying control system.Background technique[0002]The rudder gap and amsensic automatic detection device is a terrestrial device for each model aircraft, which is suitable for the aircraft to replace the actuator, check the gap of the rudder surface of the flying control system when the actuator is replaced. And amplitude.[0003]Domestic and foreign airplane flying control system rudder gap measuring multi-manually load rudder driving force, with analog circuit acquisition sensor signal; the rudder side amp value is measured by the measurement, and the rudder pairing results are obtained through the test personnel. Problems include: low measurement efficiency, low measurement accuracy, and low measurement results.Inventive content[0004]The present invention proposes a method based on an embedded rudder gap and a pairing automa...
