Research and Application of Engineering Vehicles Data ac-quisition display system based on SAE J1939 Protocol

Abstract

工程车辆工作环境恶劣,对工程车辆安全性能有较高要求。若能将工程车辆整车运行状态及时、准确反馈给驾驶员、并提供故障预警,将有效降低事故发生的风险。工程车辆参数显示仪表盘作为车载电子的重要部件,是驾驶员获取整车运行状态的窗口,对汽车安全起重要作用。 为了应对车载网络通信节点数量的急剧增加以及电子线束的日趋复杂,德国博世公司研发了一款串行通信总线CAN,该总线具备低成本、灵活性好、高可靠性与实时性得到各大汽车生产商的亲睐。SAEJ1939协议是美国汽车工程师协会参照CAN2.0B基础,为重卡、大型客车领域车载通信系统做统一的协议规定,是工程车辆领域应用非常广泛的通信协议。 本课题针对上述背景,通...Engineering vehicles are mostly used in a relatively tough and complex envi-ronment, so higher standards and requirements about their performance safety are put forward. If the operation information of the engineering vehicles is timely and accu-rately acquired by the operators and fault early warning is provided, the possibility of accident will be greatly reduced. The engineering vehicles’ param...学位:工学硕士院系专业:航空航天学院_机械制造及其自动化学号:1992013115288
