摘　　要：针对视频监控中的云台高效控制问题,提出了一种基于虚拟仪器技术的分布式无线控制系统设计方案;整体分为监控中心子系统和分布于各云台的控制端子系统,彼此通过ZigBee网络实现高速通信;设计中,基于虚拟仪器开发环境LabWindows/CVI实现了监控中心子系统研发,利用USB总线进行高速数据传输,为用户提供了友好、高效的控制平台;基于嵌入式ARM7处理器LPC2114和开源实时操作系统uC/OS-II设计了云台控制端子系统;测试表明,系统具有功耗低、灵活性高以及响应速度快等优点,方案科学可靠、实用性强,具有较高的应用和推广价值。To solve the issue of efficient control pan--tilt, a wireless distributed control system is designd based on virtual instrument. It is divided into the monitoring center subsystem and the pan--tilt control system, communicating through the ZigBee network with each other. The monitoring center subsystem is designed based on virtual instrument LabWindows/CVI and USB bus. It can provide users with a friendly, efficient control platform. The pan--tilt control systems are designed based on the ARM7 microprocessor LPC2114 and μC/OS-Ⅱ. Testing has shown that the systems have low power consumption, high flexibility and advantages such as fast response. The programme is science reliable, practical, has application and popularization of high value.
