摘要 为解决径流小区径流采样中有线数据传输带来的传输不便的问题,基于无线局域网(ZigBee)技术,设计了一种低功耗的径流场水土侵蚀采样系统,用于自动采集雨后地表径流样品,并记录径流的采样时间等参数。装置采用TI公司的CC2530为核心控制器,负责无线数据收发及采样装置控制。该系统由无线手持机和多台径流采样装置组成,无线手持机和径流采样装置组成星型ZigBee网络传输数据,手持机作为中心节点负责整个网络的管理及对各个采样装置的控制,径流采样装置作为网络分节点,根据中心节点设定的采样规则自动对径流进行分离采样。该系统使用12 V铅酸电池作为供电电源,实现了硬件和软件的低功耗设计。通过径流场的现场实验,验证了该系统具有使用方便、稳定性好和可靠性强等优点。 In order to solve the transmission inconvenience caused by cable data transmission in runoff sampling,based on a wireless local area network( ZigBee) technology,a low-power sampling system for water and soil erosion in field runoff is designed. It is used to automatically collect the surface runoff samples and to record the sampling time and other parameters. TI company’s CC2530 microprocessor is used as the core controller which is responsible for the wireless data transceiver and sampling device control. The system is composed of a wireless handheld device and a plurality of runoff sampling devices. Wireless hand-held device and runoff sampling device are composed of star ZigBee network for data transmission,the hand-held machine as the center node is responsible for the management of the entire network and the control of each sampling device. The runoff sampling device is a network node points separating runoff automatically according to the central node sampling rules. The system uses 12 V lead acid battery as the power supply,and realizes the low power design of the hardware and software. Field experiment shows that the system has the advantages of convenience,stability and reliability.
