中文摘要：

农业物联网系统包括感知、传输和应用3个层次。传感仪器是感知层的核心，包括利用传感、遥感等先进技术手段获取作物、土壤、环境等农业多维信息；传输层包括Zigbee、GPRS、WIFI、蓝牙等无线传输方式和网络技术结合形成无线传输网络；应用层包括多维信息融合、智能决策、自动控制等农业智能化管理。对农业物联网的3个层次分别展开了系统分析，提出了农业物联网研究方向，展望了农业物联网系统在现代农业中的发展趋势。

英文摘要：

The internet of things （IOT） in agriculture consisted three layers, including perceive, transportation and application. The perceive layer were used to acquire the information of crops, soil and environment. The transportation layer was used to establish the transportation network of IOT in agricultural by combing the techniques like GPRS, Zigbee, WIFI, Bluetooth and the intelligent networking methods. The process layer focused on the intelligent management of agriculture, including multidimensional information fusion, intelligent decision and automatic control, et al. The key problems, research emphasis and application fields of IOT in agriculture include three layers were discussed in detail and analyzed. The prospect and development trend of IOT in agricultural in modern agriculture was put forward.
