Design And Implementation Of Smart Data Acquisition System Based On The Bluetooth

With the continuously improvement of science and innovation of technologies related, the use of bluetooth technology is growing even faster in many aspects, in daily work and life. Bluetooth technology, high-dependability, low power and cost, is a kind of communication standard for wireless and short distance, which gives the convenience for use. It aims to replace the cable between the information equipments with radio wave and establish a personal area network to communication with each other. The main research content of this thesis is to design and implementation a smart system based on the communication technology of bluetooth.This thesis aims to research, design and realize a smart system based on the communication bluetooth technology. The contents mainly include the design of system hardware platform and software development based on this hardware platform, emphatically analyze the process how to set up the system hardware platform and how to design the important modules' software and hardware. After analysis of the system requirement of function, a embedded system which uses ATmega128L as microprocessor is designed on the hardware platform, which includes bluetooth module, data acquisition and processing module, real-time clock module, power module and man-machine interaction module. The data acquisition and processing module include sensors, analog-digital converter and Flash chip, respectively used to acquire, convert and memory the field data. Real-time clock module supplies the function of pre-setting system clock time for users. On the software platform design aspect, every module's driver is designed, the embedded real-time operating system uC/OS-II is transplanted and application program based on it is compiled, file system for Flash is also designed so as to conveniently operate and manage the data files.At last, the system test result is supplied which proves that the system requirement of function and performance required is achieved. The system has a reasonable hardware circuit design, flexible interfaces. Base on uC/OS-II, the application program is developed easily, flexibly and efficiently. Most of all, the bluetooth module works normally and stability, it is easy to be further developed.
