針對工程機械遠程監控與智能維護的需要，研究開發了一種基于CAN總線的無線數傳
終端。該終端基于工程機械本身的CAN總線控制系統，采用嵌入式技術，以數字信號控制器TMS320F2808和GPRS/GPS二合一模塊XT55為核心，融合CAN、GPRS、GPS和DSP/BIOS技術，通過CAN網絡和工程機械內部控制系統無縫集成，實時采集裝備的運行狀態參數，采用GPRS方式將數據發送至服務器。跨地域實驗表明，該終端適用于對工程機械的遠程監測，對實現設備的跟蹤和主動維護具有積極的現實意義。

Abstract ： According to the Construction Machinery Remote Monitoring and Intelligent
maintenance, this paper introduces a new kind of wireless-data-transmission terminals based on CAN bus. The terminal itself based on the construction machinery CAN bus control system, using embedded technology ,making digital signal controller TMS320F2808 and GPRS / GPS Combo modules XT55 at the core, blending CAN,GPRS,GPS and DSP/BIOS technology, seamlessly integrating itself with internal control system of engineering machinery by CAN bus, gathers real-time running parameters of the equipment and sends them to the server by GPRS means. Transregional experiments showed that the terminal was fit for the remote monitoring of construction machinery, and would have a positive and practical significance. to achieve the track of equipment and the active maintenance.
