摘要
随着CAN总线在汽车电子中的大规模推广及应用，需要一套支持CAN 总线网络开发、分析及测试的软件工具进行CAN网络和单个汽车电子单元的设计．由于购买商用的CAN总线开发分析工具成本高昂，其需绑定特定CAN卡，无法进行并行开发．笔者所在团队采用Eclipse作为开发平台，以Java和JNI方式实现了一种低成本的CAN网络开发及分析工具，该工具包括网络协议设计工具和总线监控工具两部分，网络协议设计工具实现信号矩阵设计并给出网络信号的多个视角，生成XML格式的信号矩阵做为与总线监控工具的接口．CAN总线监控工具实现对所选普通CAN卡的控制和接口，通过CAN卡接入到CAN总线网络中，进行总线数据的实时监控并给出数据的多个视角以进行深入分析．
With the large -scale promotion and application of CAN bus in automotive electronics,a set software tool supporting the development,analysis and test of CAN bus network is required for the design of CAN network and single automotive electronic unit.Since the CAN bus development and analysis tool adopted by the buyer is quite expensive and it should be bonded to specific CAN card, it is not applicable for parallel development.The team of the author realized a low-cost CAN network development and analysis tool with Java and JNI by taking Eclipse as the development platform.The tool mainly includes two parts,namely the networking protocol design tool and bus monitoring tool.The former realizes the design of signal matrix,provides several views for the network signal,and generates XML signal matrix as the interface of bus monitoring tool;while the latter realizes the control and interface of ordinary CAN card,which will carry out the real-time monitor of bus data and provide several views of the data for further analysis through connecting CAN card to the CAN bus network.
