模型遙控2.4ghz系統(tǒng)的設計與實現(xiàn)

1、 IIABSTRACT With the development of electronics technology, various controls applied to the radio equipment aircraft model began to be popular. The remote control equipment has undergone earth-shaking changes, the weight

2、 is lighter, and the speed is quicker and the power dissipation is fewer and fewer, modulation frequencies experience AM, PPM, and PCM. The reliability is more batter, and the frequency used is more and more higher. So i

3、t becomes more and more convenient. It requests our model technical designers must have an obligation to improve technical content of the model, this article mainly research the current world model skill and design a new

4、 technology, 2. 4GHz DSSS control system, hope to make up for domestic technology gap. This thesis detailed account of the wireless remote control system design, the main form of the soft hardware and then described for

5、 the each module design block diagram and functions. In this thesis, the first thing is introduce to the overall scheme of the system, then profound study the expand spectrum of communications technology, simultaneity co

6、mparative analysis frequent hopping and direct sequence both expand spectrum of merits and faults. By the end, DSSS has been chosen in this 2.4GHz remote control system. For the hardware, under the development of the pla

7、tform Protel99, I have completed drawing the circuit design and printed circuit board design, and I use MEGA8 as the master control processor and CYRF6936 as RF IC. I also improve the printed circuit board's electrom

8、agnetic compatibility, the arrangement of the radio frequency circuit and the aerial system. By the software side, under the development of the CVAVR platform, I have finished the SPI of drivers and application as well a

9、s the serial communication protocol and wireless communications protocol program written of the CYTF6936. In the end, I complete the development and manufacture of the whole product. Practice has proved this system has r

10、eliability, strong anti-interfere and high performance-price ratio. This system is available later in Europe and USA and Japanese market to get a good feedback, and made a very good market share. Key word: Remote contro
