【摘要】 随着时代的发展和科技的进步,与人们生活密切相关的照明系统也越来越智能化。常规照明控制系统是一对一通信,布线困难。使用现场总线的智能照明控制系统实现了本地照明控制系统小范围内的照明集散控制,但其开放程度低,甚至系统是封闭的。为实现对本地照明控制系统的远程监控和信息共享,设计了一种网络化智能照明控制系统。网络化智能照明控制系统是将本地照明控制网络通过智能网关连接到以太网。针对学校教学楼内教室照明控制系统智能化和网络化控制的需要,设计一个具有以太网和CAN协议转换功能的智能网关,以及具有智能控制功能的终端节点,并将以CAN组网的终端节点通过智能网关接入以太网,从而实现对终端节点的远程监控和配置,以及数据共享。所做工作包括系统总体方案的设计,硬件部分完成了智能网关和终端节点的硬件电路设计,软件部分完成了智能网关的CAN模块和以太网模块的驱动并移植了LwIP协议,根据iCAN标准协议设计了智能网关的以太网应用层协议和CAN应用层协议。最后对智能网关的软硬件进行了调试,实验结果表明智能网关实现了以太网和CAN两种协议的透明传输,相关工作为教学楼网络化智能照明控制系统的完整设计与实现奠定了基础,对其它需要远程控制的应用场合也具有参考意义。更多还原

【Abstract】 With the development of the time and technology, lighting system related to people’s daily lives is becoming increasingly intelligent. Communication of the conventional lighting control system is terminal to terminal and system’s cabling is very difficult. Intelligent lighting system using the fieldbus has achieved distributed control for local lighting control system whithin a small range, but it has a low degree of openness and the system is even closed. To realize remote monitoring and information sharing towards local lighting control system, a kind of networked intelligent lighting control system is designed.Networked intelligent lighting control system can connect local lighting control system to Ethernet through an intelligent gateway. In order to meet the needs of intelligent control and networked control for classroom’s lighting control system in teaching buildings of university, we design an intelligent gateway which has the function of converting protocol between Ethernet and CAN and design a terminal node which has intelligent control function, and terminal node networking with CAN can be connected to Ethernet through an intelligent gateway, so terminal node can be configured and remote controlled and at the same time data can be shared. The work of this paper includes the design of overall program. As for the hardware, hardware circuit design of the terminal node and intelligent gateway are completed. As for the software, CAN module’s driver and Ethernet’s driver are completed, LwIP protocol is transplanted and Ethernet’s application layer protocol of the intelligent gateway and CAN-bus’s application layer protocol are designed according to iCAN standard protocol. The hardware and software of the intelligent gateway are debugged at last, and the result shows that the intelligent gateway realized transparent transmission of CAN protocol and Ethernet protocol. Related work laid the foundation for complete design and implementation of teaching buildings’s networked intelligent lighting control system, and it also has some reference value to other remote control application.更多还原
