摘要
LonWorks总线具有开放性、可靠性和可互操作性等优点,在工业通信、楼宇自动化等领域有着广泛的应用。设计并实现了LonWorks试验系统,作为学生深入理解LonWorks通信机制和关键技术。在硬件设计中解决了神经元芯片扩展多个I/O设备的问题;软件设计采用了模块化的设计思想,并且提出了一种页面显示与控制的程序流程。对基于该试验系统的试验项目进行了简要介绍。试验系统有良好的人机交互界面,而且操作简单。
LonWorks has some outstanding advantages of opening,reliability,interoperability,and has been widely used in industrial communication,building automation and so on.This paper designed and realized an experimental system of LonWorks.In the hardware design,the problem of the neuron chip expansing multiple I/O devices is solved.Modular design idea is used in the software design,and this paper put forward a program flow of page display and control.It also gave a brief introduction of experiments based on the system.The experimental system offers a comfortable human machine interface which is easy to operate.
