The Design Of Data Collection Platform Based On ARM9 And The Port Of μC/OS-Ⅱ Operating System

Wireless communication plays an important role in military communication.As the frequency-hopping communication technology has the advantages of anti-jamming,low intercept, multiple access network,anti-fading and easy compatibleness, it is widely used in tactics communication.Many experts predict that the future equipment in tactics communication is frequency-hopping broadcasting station.Modern army asks for wireless station not only with ability for voice transmission but also with function of data transmission in order to supply the system of C4 I.Therefore,the frequency- hopping broadcasting station which has the function of data transmission becomes the focus.This thesis takes advantage of ARM andμC/OS-II operating system to realize the data collection and data transmission of frequency-hopping broadcasting station.Firstly, it presents systemic structure and designs software platform based on the hardware platform.Secondly, it designs and realizes bootloader and portsμC/OS-II to AT91RM9200 microprocessor.Thirdly, it finishs data collection and data transmission of frequency-hopping broadcasting station and realizes the function of the Data Link Control Layer in data terminal. In the end , this thesis romed the user code .It is proved that the system has good results of data collection and data transmission.
