| Summary: | 碩士 === 國立臺北科技大學 === 電腦與通訊研究所 === 101 === The wireless communication is vigorous development nowadays. Wireless communication systems are most widely used for industrial and automatic control, such as wireless remote control, wireless keyboard, wireless mouse, gamepads and 2.4GHz ISM-band communications system. Therefore, in this thesis, an 8051 microcontroller combined with 2.4GHz RF IC are used to build a remote control system.
Firstly, the features of the microcontroller (C8051F930) and the 2.4GHz RF IC(A7125) is introduced. Then, the detailed description of the firmware design process, frequency, power and data rate setting are given in detail. Finally, the implementation of the proposed system is presented.
C++ Builder is used to perform the user interface of the transceiver. At transmitter, user can send single or multiple GPS location information (longitude, latitude and altitude) to receiver. The program of receiver has noise dismiss function, when received data are not number or decimal point characters, the program doesn`t accept this information of location, or when the distance between two positions is too far, the program doesn`t accept these data, either. If these two conditions are met, these data will send to turn the rotation table and let the Automatic Tracking Antenna System (ATAS) turn to the right position.
In this thesis, a low-cost and robust system is designed. An efficient software is programmed to reduce the operation complexity. In addition, the proposed system can be used in any wireless system, such as tracking the UAV (Unmanned Aerial Vehicle) or academic rockets.
