摘　　要：为研究空气污染物扩散情况,基于学习型无线遥控传感器,采用气体直接采样法设计了一种多点组网的便携式大气采样器。可实现灵活多变的大气污染监测采样,对大气污染扩散研究提供有效样本。通过学习型无线遥控传感器的学习功能,实现了多采样器同步采样和延时采样灵活控制,完成采样器组网。采用脉宽调制（PWM）方式调整采样器的采样速度,采样速度0.1-0.8 L/min可调。对该采样器进行了测试,测试结果表明：设计的大气采样器达到预定指标,可以实现大气可靠自动采样。A multi-point networking portable air sampler is designed using direct sampling methods based on wireless remote sensors. It enables flexible air pollution monitoring and sampling,and provide an effective sample for diffusion of atmospheric pollution. It can achieve flexiable control of synchronization sampling and delay sampling by multi-sampler,complete sampler networking. Using PWM mode to adjust sampling rate of sampler,sampling rate can be modulated at range of 0. 1 - 0. 8 L / min. The sampler is tested,and results show that the multi-point network sampler can achieve reliable and automatic air sampling.
