基于CAN总线的发动机机械性能测试分析

Test Analysis of Engine Mechanical Properties Based on CAN

新兴科学技术的不断创新以及高新技术的发展,对农业机械产生了巨大的积极影响,为提高农业动力机械性能开辟了新的途径。为此,介绍了CAN总线的基础知识、主要特性以及CANoe软件开发环境。为了检验设计的CAN总线系统的参数是否符合ISO11898,利用自行研制的CAN总线系统测试台架对CAN信号电平以及比特率进行测试分析。测试表明,CAN信号电平及比特率都符合发动机机械性能动力总成的要求。

The development of the new technology,especially for the computer science and electronic information technology,Which have broken great effect on agricultural mechanization. These technologies open up the new avenues to improve the performance of agricultural power machinery. The paper mainly introduces the based concept about the CAN bus and the application of CANoe software. In order to inspect the characteristic parameters of the CAN bus system compliance with ISO 11898,The analysis of the CAN signal level and bit-rate are done by the use of CAN bus system test bench,the results showed that,CAN signal level and bit rate are consistent with the requirements of engine mechani-cal properties system.
