Teaching experiment device for aircraft navigation, guidance and control technology

Abstract

The invention relates to a teaching experiment device for an aircraft navigation, guidance and control technology, comprising a missile-borne controller, a real-time task management subsystem, a missile body structure, an electric rotary table, a user interface subsystem and a student experiment PC (Personal Computer), wherein all the modules are connected and communicated by adopting a serial port, a digital I / O (Input / Output), an Ethernet or radio, and the like; the missile-borne controller can be arranged in the electric rotary table or the missile body structure and is communicated with the real-time task management subsystem through the radio or the serial port; and the missile-borne controller and the real-time task management subsystem realize the configuration of experimental resources, such as an inertial measurement unit, a steering engine, the digital I / O, an equivalent device, the serial port, a network port, and the like, through the design of software and hardware. The teaching experiment device not only has the experimental functions for a module carrying out the principle demonstration of an aircraft, a sensing device module, an actuating mechanism module, a missile-borne controller module, a control system synthesis module, and the like, but also can be used as an experimental platform for a user to carry out independent design and research; and in addition, the teaching experiment device has the advantages of simple and compact structure, low cost, complete content, high function integration degree, easiness and convenience for operation, wide application scope, and the like.

Description

technical field [0001] The present invention mainly relates to the field of aerospace experimental equipment, in particular to an experimental teaching instrument for navigation, guidance and control technology, which is mainly used in the teaching, research and training of aircraft design majors and navigation / guidance control majors in colleges and universities. The principle demonstration experiment module, the sensitive device experiment module, the actuator experiment module, the missile-borne controller experiment module, the control system comprehensive experiment module and the user-independent design experiment module and other functions can be used by students at the component level, system level and test evaluation level. Experiment on three levels. Background technique [0002] In the 21st century, aerospace technology has been widely recognized by the whole society from the height of strategic technology that our country prioritizes development, and the higher e...

AI Technical Summary

Problems solved by technology

[0005] 1. Since the experimental equipment adopts the scientific research experimental environment or is built according to its structure, the cost of the equipment is generally high, and the number of sets is difficult to guarantee, and this type of equipment has high requirements for the operation of the user, and it is difficult for students to participate in the experiment, resulting in this Class experiments stay at the demonstration level;

[0006] 2. Lack of systematic design of experimental content and development of special experimental modules. Experiments cannot be systematically arranged according to the teaching experiment outline. Experiments are carried out only by scattered navigation / guidance control equipment or highly targeted professional-level test systems, which directly leads to The experimental content is incomplete, the system is not complete, the connection between each experimental content is loose, and the experimental effect is not ideal

Due to the small investment in education funds in our country, the large number of students, the uneven foundation of various colleges and universities, the guarantee of experimental conditions cannot be fully guaranteed, and the European and American training models are not suitable for my country's current national conditions. For a long period of time, most colleges and universities It is difficult to carry out experimental teaching in accordance with the European and American training models, especially for undergraduate and postgraduate experimental teaching with a large number of students;

[0007] 3. There is a lack of special experimental operation software, the operation is complicated and professional, the programming workload in the experiment is heavy, and the requirements for related technologies (such as: electronic engineering, control system, program design, etc.) are relatively high. Students use professional theoretical knowledge to conduct experimental research The additional workload is too large and the experimental efficiency is low
