嵌入式ARM 處理器是當今世界上最流行的嵌入式處理器,廣泛應(yīng)用于個人通信等嵌入式領(lǐng)域。基于Linux 良好的開放性和USB 總線極佳的通用性,本文通過在ARM920 T 處理器的開發(fā)板上實現(xiàn)嵌入式Linux 系統(tǒng),并重點描述了Linux USB 設(shè)備驅(qū)動程序的實現(xiàn)過程。
提出了一種以ARM微處理器為控制核心的遠程無線視頻監(jiān)控終端的設(shè)計方案,其監(jiān)控終端的硬件設(shè)計包括視頻采集處理、中央管理控制、無線傳輸3個模塊。并給出了監(jiān)控終端的軟件開發(fā)平臺和開發(fā)模式的系統(tǒng)啟動代碼、嵌入式Linux系統(tǒng)移植以及驅(qū)動程序和應(yīng)用程序。測試結(jié)果表明,該監(jiān)控終端設(shè)計方案合理、有效,基本滿足監(jiān)控需求。
Abstract:
A remote wireless video monitoring terminal design, which uses ARM microprocessor as its core control, is proposed in this paper.The hardware design of monitoring terminal system is composed of the video acquisition and processing module, the central management and control module, wireless transmission module.Meanwhile the monitoring terminal-s software development platform and development patterns are designed. Also the design of the system-s start codes, embedded Linux system-s transplantation process, driver and the corresponding applications are given. The results showed that the monitoring terminal design is reasonable, effective, basically meet monitoring requirements.
