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.
