新型分布式智能楼宇电源无线控制系统的设计

摘要

针对园区智能楼宇群的供电电源高效控制问题，提出了一种分布式无线控制系统设计方案；整体分为监控中心节点和分布于各楼宇的控制节点，彼此通过 ZigBee网络实现高速互联；中心节点采用上位机/下位机结构，利用 USB总线实现高速数据传输，基于LabWindows/CVI虚拟仪器技术实现上位机的软件研发，为用户提供了友好、高效的控制平台；楼宇控制节点基于嵌入式微处理器MSP430和开源实时操作系统μC/OS-II设计实现，采用多路双向可控硅精确控制电源的状态切换；测试表明，系统具有可靠高效、灵活实用及响应快速等特点，具有较高的应用和推广价值。%To solve the issue of efficient control of park intelligent building group,a distributed wireless control system is designed.The control node is divided into the center node and distributed nodes,which communicate each other with the ZigBee network.The center node includes the host computer and slave computer,and the high-speed data transmission is based on USB bus.The virtual instrument develop-ment environment LabWindows/CVI is used to develope the control platform.The system provides a friendly,efficient interface to the users;the building control nodes are designed based on the embedded processor MSP430and open source real-time EOSμC/OS-II.The testing results show that the system has a high efficiency,flexible,fast response,and strong practicability,and has high value of application and promotion.
