拖拉机CAN总线车载智能终端技术研究

Research on the Technology of CAN Bus on Vehicle Intelligence Terminal for Tractor

为了将智能车载终端应用于大型拖拉机上,对拖拉机CAN总线车载智能终端技术进行了研究。该车载智能终端系统由农机CAN总线数据解析器及车载计算机等组成。农机CAN总线数据解析器根据ISO11783农机CAN总线协议,对拖拉机作业产生的CAN数据进行解析,并使用VB6.0软件编写了车载计算机应用程序。该程序能够对解析后的CAN数据进行处理、存储、传输和显示。车载智能终端具有拖拉机作业参数实时监测、作业轨迹显示、虚拟仪表等功能,能够辅助驾驶操作和精准管理。

In order to apply intelligent vehicle terminal to the heavy tractor, the intelligent terminal technology of CAN bus is studied. The vehicle intelligent terminal system is composed of a CAN bus data parser, a vehicle mounted computer, and the like. Agricultural machinery can bus data parser based on iso11783 agricultural can bus protocol, on tractor can data analysis, and uses VB6.0 software to compile the on-board computer application program, the program can and processing, storage, transmission and display of can parse the data. The vehicle intelligent terminal has the function of real-time monitoring, working track display, virtual instrument and so on, which can carry on the assistant driving operation and the precision management.
