摘　　要：在已有的Zigbee无线火灾报警探测系统的基础上,设计了一种功率控制方案并运用于改进该系统,实现了基于功率优化的Zigbee无线火灾报警探测器。介绍功率控制的理论依据和方案的设计与实现,并进行系统功耗分析。实验室测试结果表明,该方案不仅能够有效降低探测器通信功率,延长探测器电池使用寿命10%以上,而且可依据无线系统通信链路质量来自适应选择最优的通信功率。Based on the existing Zigbee wireless fire alarm detection system, a power control program was designed and used to improve the system, and Zigbee wireless fire alarm detector based on power optimization was achieved. The power control theory and the program design and realization were introduced, and the system power analysis was carried out. Experimental results showed that, the program can not only reduce the detector communication power, and extend the battery life for 10 %, and also adaptively select the optimized communication power based on wireless system communication link quality.
