摘　　要：针对目前国内气象数据采集器几乎是利用国外产品的现状,给出了一种基于ARM(Advanced ReducedInstruction Set ComputerM ach ines)嵌入式处理器的多通道气象数据采集系统的设计方法。通过软、硬件技术的结合,实现了8通道模拟信号的采集,发挥了嵌入式系统在气象数据采集系统中的运用优势。同时采用CF(Compact F lash)卡存储技术和USB2.0(Un iversal Serial Bus 2.0)技术、以太网通信方式,弥补过去气象数据采集器通信方式单一、存储方式固定、软件设计复杂等缺点。实验结果表明,该数据采集系统采样精度达到14 b it,采样率为140 kHz/s,并实现了CF卡存储和3种不同通信方式。Being short of domestically produced meteorological data collecting systems, a kind of design method of the multi-channel meteorological data collection system based on ARM （Advanced Reduced Instruction Set Computer Machines） is presented. By combining the software technology with the hardware technology, eightchannel analog signal collecting system is realized. It demonstrates the practical advantages on the application of the embedded system in the meteorological data collecting. It also remedies the shortcomings of the current meteorological data collection system, such as single communications interface, stable data storage, the complexity of software design because of our adopting CF （ Compact Flash） storage technology, USB2. 0 （ Universal Serial Bus 2. 0） technology and Ethernet technology. The experimental results show there are 14 bit collection precision and 140 kHz/s sampling rate in this system. In addition CF storage and three communications ways are attained.
