Remote control aircraft program
The core control part of the remote-controlled camera plane designed in this paper adopts the representative product 80C51 in the family of single-chip microcomputers. It is one of the classic 51 series of microcontrollers. The 51 series single-chip microcomputer was launched in the 1980s. It is the most classic representative of the single-chip microcomputer family and has a profound impact on the production of the entire single-chip microcomputer.
1. Introduction to SCM technology
Single-chip microcomputer emerged in the 1970s. After years of development, it has developed from 4-bit and 8-bit to the current 16-bit. From the time it was only used in the industrial field to the present, single-chip microcomputer products have penetrated into all aspects of our lives.
As a milestone of control technology, single-chip microcomputer technology is widely used in industrial control, intelligent instrumentation, household appliances and other fields. Single-chip microcomputer is the abbreviation of single-chip microcomputer. It adopts ultra-large-scale integration technology, which integrates the central processing unit, memory, and input/output interface circuits of the microcomputer on the same chip. It constitutes a compact and complete computer hardware system, and under the control of the application software of the single-chip microcomputer, it can accurately, quickly and efficiently complete the prescribed control tasks. Therefore, a single-chip microcomputer chip has all the functions of a computer. As the core of the control system, the single-chip microcomputer chip must have flexible and powerful control functions in addition to the numerical calculation functions of the general-purpose microcomputer CPU. It has strong anti-interference performance, large working temperature range span, high reliability, strong control function, and strong numerical calculation ability; and the instruction system of the single-chip microcomputer is relatively simple and rich. The application of single-chip microcomputer has also changed the design ideas and methods of traditional control systems. Some functions that used to be realized by hardware analog circuits can now be controlled by digital circuits through single-chip microcomputer programming.
2. Design of remote control aircraft
The entire fuselage is made of lightweight materials, such as the wing parts are made of rigid foam. The whole machine is divided into four parts: nose, fuselage, wings and tail. The nose is connected with the propeller, and the propeller is adjusted according to the size and weight of the aircraft. The fuselage is the core part of the whole aircraft. The fuselage is airtight and has a built-in remote control signal receiver, flight control system and camera for taking pictures. The wings are made of light materials, and the size is adjusted according to the weight of the fuselage. The connecting part of the wings and the fuselage is a rotating shaft device, which can adjust the direction during takeoff and landing. The tail is connected to the empennage, and an emergency landing safety device can also be installed at the end part to prevent the fuselage from being damaged when the aircraft fails to fly or lands.
3. The internal design and function of the fuselage of the remote control aircraft
The core part of the fuselage is a sealed cabin, including batteries for power supply to the whole machine, take-off switch, power switch, remote control signal receiving device, flight and camera control system, camera, various sensors, flight control program import interface, and photo export in the camera interface, battery charging interface.
The battery is a rechargeable battery that can be used repeatedly. The function of the power switch is to control the circuit connection between the battery and the core part of the fuselage. The function of the take-off switch is to control the propeller and the flight control system. After the remote control terminal has set the flight route, time, and distance of the aircraft, the settings will be imported into the control system through the interface, and the take-off switch will be turned on. flight route.
The main functions of the flight and camera control system are: automatically climb to the preset altitude of the system, automatically fly according to the set route, automatically control the camera to take pictures according to the set time and interval, automatically return to the flight, automatically reach the landing altitude, Automatically turn on the landing safety device within the set landing radius, automatically retract the camera lens, automatically cut off the power, etc.
A variety of sensors mainly include relative altitude sensors, temperature, humidity, wind sensors, etc. The flight control program import interface and the camera photo export interface are the only ways for the aircraft to interact with the control terminal or the outside world.
4. Functions of remote control aircraft control terminal
The control terminal is used in conjunction with the flight control system in the aircraft. The control terminal can perform pre-flight route and required settings, and can also complete temporary control tasks. The main functions of the control terminal include: obtaining signal connection with the aircraft, planning the aircraft route, planning the flight altitude, planning the flight area, real-time monitoring of the aircraft status, emergency handling of emergencies, post-processing image processing, and measuring part of the shooting area.
The terminal has a built-in aircraft supporting control software, which can set the flight route, etc. After the setting is completed, it will be imported into the flight control system of the aircraft through the interface with the flight control program import, and the control system will fly according to the preset settings.
The flight control software includes several modules such as aircraft control, camera control, and telemetry recording. Through the communication between the control terminal and the sensors in the aircraft, the control software can monitor the aircraft voltage, flight speed, relative altitude, air humidity, wind speed, air pressure, etc. The aircraft control part of the software can pre-set the length, width, height, flight radius of the flight area of the aircraft, the height, time interval, and range of camera shooting, etc. By communicating with the built-in remote control signal receiving device of the aircraft, the control terminal can also perform real-time flight remote control.
5.The application field of remote control aircraft
The remote control aircraft has a wide range of applications and can be used in military, meteorological, agricultural and other fields. In the military field, it can be used to survey physical terrain and landforms, and to carry out reconnaissance work; in meteorology, it can be used to collect specific weather pictures and landform pictures, and to test related meteorological parameters such as wind speed, air pressure, humidity, temperature, etc.; in agriculture It can be used to survey plant growth and branch conditions, survey crop damage, and determine the affected area and affected area. The application of remote control aircraft can save a lot of manpower and material resources, and collect images from a bird's eye view in the air; collect images and various parameters in dangerous situations or when people cannot reach them.
