針對工程機械遠程監(jiān)控與智能維護的需要，研究開發(fā)了一種基于CAN總線的無線數(shù)傳
終端。該終端基于工程機械本身的CAN總線控制系統(tǒng)，采用嵌入式技術，以數(shù)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(wǎng)絡和工程機械內(nèi)部控制系統(tǒng)無縫集成，實時采集裝備的運行狀態(tài)參數(shù)，采用GPRS方式將數(shù)據(jù)發(fā)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(jiān)測，對實現(xiàn)設備的跟蹤和主動維護具有積極的現(xiàn)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.
