針對汽車儀表行業發展的新趨勢,文中提出了一種基于Labview的新型數字式車載信息終端的解決方案。其中包括基于CAN 總線的分布式傳感網絡的設計,嵌入式網關的設計,基于SD卡的黑匣子系統和Labveiw平臺下的人機交互界面的總體框架。為了減少對汽車前面板空間的占用,設計還集成了后車影像和汽車導航這兩個常用功能。同時,利用WIFI 協議和Labview的 WEB Server技術實現了遠程對汽車信息的訪問。與現有產品相比,該系統具有成本低、體積小、智能化、易升級等特征。
提出了一種以ARM微處理器為控制核心的遠程無線視頻監控終端的設計方案,其監控終端的硬件設計包括視頻采集處理、中央管理控制、無線傳輸3個模塊。并給出了監控終端的軟件開發平臺和開發模式的系統啟動代碼、嵌入式Linux系統移植以及驅動程序和應用程序。測試結果表明,該監控終端設計方案合理、有效,基本滿足監控需求。
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.
