摘　　要：针对空调压缩机有线数据采集系统存在的不足,结合空调压缩机的结构特征,从传感器节点的低成本低功耗角度出发,利用单片机MSP430和nRF905芯片在电池供电的低功耗应用中具有的优势,提出了一种无线数据采集系统的方案。该方案利用nRF905的跳频机制以及帧扩展的方法实现了低功耗芯片nRF905构成的完整的通信协议,实现了网络的通信功能,有效地减少了通信的误码率,提高了系统的可靠性。实验结果表明该系统设计合理,性能可靠,对空调系统的节能具有重要意义。Regarding insufficiency of wired data acquisition system of air-conditioning compressors for the past and combining with the structural characteristics of air-conditioning compressor, this paper presents a program of wireless data acquisition system, which takes advantage of superior MSP430 SCM and nRF905 chip in the low-power applications of battery-power and view of cost-effective and low-energy consumption of sensor nodes .The program constitutes a complete communication protocol of low-power nRF905 chip by the use of frequency hopping of nRF905 and frame extension method , which meets the needs of the network communication function ,effectively reduces the error rate of communication and improves the reliability of the system . Experimental results show that the design of the system is reasonable and reliable, which is great significance energy-saving of air-conditioning systems.
