摘要
针对汽车控制现场温度变化范围大,环境恶劣,干扰强的特点,设计了一种基于CAN总线技术的电涡流缓速器实时控制系统,完成对现场实时参数的采集、处理和控制。同时给出了一种基于LPC2119的CAN总线接口设计流程,较详细说明了CAN控制接口的硬件电路及软件实现方法,并介绍了系统采取的各种抗干扰措施。经试验测试表明能很好地监控系统运行状态和提供可靠、准确、实时的数据参数。
In allusion to the characteristics of large variation in temperature, adverse environment, strong interference in the control field of car, a kind of real-time control system of eddy current brake based on CAN bus was designed. It can acquire, deal with and control the real-time parameter. A design of CAN bus system based on LPC2119 was described. The hardware circuit and software design of the CAN control interface were presented in detail. The anti-interference technologies in the system were expoun- ded specially. The test showed that it can monitor the running state of the system and provide reliable, accurate and real-time envi- ronmental data parameters.
