楼宇自动化的设计课题.doc

摘要 楼宇自动化控制系统是采用现代化的传感技术、计算机通信技术对建筑物内所有机电设施进行信号采集、控制，提供有效安全的物业管理，使其设备应用在最良好的状态。本次设计是基于一套CAN总线的远程控制装置，通过CAN总线完成对现场设备的控制操作，并与CAN总线上其他设备完成数据的传输。系统硬件部分主要由AT89S52单片机、SJA1000 CAN控制器等组成，系统在硬件和软件上进行模块化设计，具体实现了以单片机为控制核心，设计了4路数字量输入，4路模拟量输出模块，以及CAN接口电路模块。CAN总线的应用，提高了楼宇智能化水平并降低了设备的管理成本。CAN总线提供了标准网络协议的数据链路层，没有相应的高层通信协议。关键词：CAN总线；控制节点；CANopen协议 Abstract Building automation control system consists of modern sensor technology, computer communication technology on buildings of all electrical and mechanical facilities for signal acquisition, control and provide effective security for property management, to equipment used in the best condition. The design is based on a CAN bus, the remote control device, through the CAN bus for control operation of field devices and other devices with the CAN bus for data transmission. Hardware of the system mainly by AT89S52 singlechip, SJA1000 CAN controller and other components, system hardware and modular software design based on single chip for the realization of the control core, designed 4 digital inputs, 4 analog output module, and the CAN interface circuit module. CAN bus applications, improve the level of intelligent building and reduce management costs of the equipment. CAN bus provides a standard network protocol for data link layer, there is no corresponding high-level communication protocol. CANopen protocol is an exoteric and standardized high layer protocol based on CAN field bus. It is a high speed serial bus system with real-time capabilities, CANopen protocol allows diffcate with each other in a standardized manner and makes them inter operable. Key words: Building control system Controller Area Network CANopen protocol 目 录 引言 1 1 第二节 现存的楼宇控制系统相关技术 2 3 第一节 总述 3 第二节 设备模型 3 第三节 对象字典 4 第四节 CANopen要点 5 第三章.系统硬件设计 7 总体设计方案 7 8 第一节 选择CANopen原因 8 第二节 CANopen协议系统软件设计 9 第三节 软件设计系统流程 10 第五章.调试结果及分析 16 第六章.结束语 17 致 谢 18 参考文献 19 附录总原理图 21 引言随着技术与通讯技术的迅速发展，光纤通信（Fiber Communication）、卫星通信（Satellite Communication）、区域网络(Local Area N
