摘要
针对当前传统照明系统存在的手动操作、布线复杂等缺陷,以及无法满足环境采集、线性调光要求的不足,提出了一种基于ZigBee无线传感网络的LED照明控制系统设计方案。该系统采用CC2530芯片,利用网状(Mesh)拓扑结构的ZigBee2007/PRO无线传感网络实时采集照明现场的光照度、移动目标、温度、LED状态等参数,随着环境参数变化以及预先设置的照明模式(手控、自控),控制系统自动做出智能判断,实现了PWM线性无极调光;基于VC6.0平台开发的PC上位机对LED照明控制系统进行了实时监控、集中管理,克服了传统照明管理落后、单一控制、人员浪费的缺陷。研究结果表明,该系统可实现"传感器节点实时采集环境参数,ZigBee遥控器准确控制,PC上位机集中管理"的设计目标,且实验数据理想。
Aiming at the defects of the current traditional lighting system about manual operation, complex wiring and so on which can＇t meet the requirements of the environmental sampling, linear dimming, the design of lighting control system of LED based on ZigBee wireless sensor network technology was presented. CC2530 chip was chosen and Mesh topology structure of ZigBee2007/PRO wireless sensor network was used by the system to acquire real-time environment parameters in lighting scene, such as illumination, moving target, temperature, LED state and so on. With the change of environmental parameters and the preset lighting mode, the system can automatically make quick response and realize PWM linear non-polar dimming. The LED lighting control system was real-timely monitored and centralizedly managed by the PC host computer based on the VB6. 0 platform to overcome the defects of traditional lighting inefficient management and staff wastage. The results indicate that the system achieves the design goal of the real-time acquisition of environment parameters by sensor nodes, precise control by ZigBee remote control and centralized management by PC and the experimental data is ideal.
