基于CAN总线电动汽车下线检测系统的开发

Development of Offline Test System for Electric Vehicle Based on CAN Bus

随着电动汽车的批量生产,电动汽车下线检测也成为一个重要的研究课题。本文中,利用便携式电脑,基于CAN总线建立汽车下线检测的实际应用的系统方案,而后对测试系统进行软件的设计与开发。在软件开发过程中,利用LabVIEW编写程序,在NI测试台架上处理测试项目,研究优化两个软件的数据库连接,最后设计用户界面用于数据库的维护和管理。通过调试,不仅验证了测试系统在测试、数据处理等方面的实用性能,并且反馈信息以加强和改善基于CAN总线系统的稳定性和可用性。

With the mass production of Electric Vehicles, the Offline test of Electric Vehicle has become an important research subject. In this paper, a scheme of the system with a portable computer is established for the practical application to the offline test based on CAN bus, and then design and research of the testing system software are followed. In the process of system software development, we program in LabVIEW, manage the test items in NI Test Stand, make a research and optimization of Microsoft Office Access database connection for both software, and design user interface program of database maintenance and management finally. Commissioning not only verifies practical performance of the test system in the aspects of testing, data processing and others, but also feedbacks the reference information to enhance and improve the stability and re-usability of the system based on CAN bus.
