SAE J1939协议是重型车辆广泛采用的一种车载网络规范,它详细定义了大量的参数,通过对车上协议数据报文的分析就可以获取车辆重要电控单元的各项状态信息.针对整车厂车辆下线检测的需求,在J1939协议应用层的功能基础上,经过需求分析并使用 PowerDesigner 建模工具对 J1939的参数数据库进行建模,建立具体数据库管理系统的物理数据库,并在此基础上利用CodeSmith代码生成工具以及.Nettiers模板来生成该数据库应用系统中数据访问层的.NET代码框架,实现车辆下线检测系统中对J1939协议参数的支持,最终完成设计.

SAE J1939 protocol is a kind of vehicle network that widely used in heavy vehicles, it defines a large amount of information in detail, the status information of some important electronic control units can be gathered up through analyzing the data message from vehicle. Aiming at the testing requirements for the vehicle manufacturers at the end of production line, a database model is built by using the PowerDesigner tools based on SAE J1939 protocol. A physical database in database management system is generated and the full .NET framework code as the data access layer of the database application system is created using CodeSmith and .Nettiers templates, which can realize the data support to the J1939 protocol in the end-of-line testing system.
