摘　　要：针对当前粮情测控系统的许多弊端,本文采用IEEE802.15.4无线个域网技术和IEEE1451.5智能传感器接口技术,构建了一种新型粮情测控系统。对该系统中的粮仓无线传感网络,给出了无线传感器节点和无线汇聚器节点的硬件设计,并提出了一种适合于粮情数据采集与传输的通信协议。实践表明,采用以上技术实现的新型粮情测控系统具有许多显著的优点。To overcome some disadvantages of the current measurement and control system for the condition of storedgrain, a new system with the same functions is constructed using two technologies-IEEE 802. 15.4 （standard for Wireless Personal Network） and IEEE1451.5 （standard for Smart Transducer Interface for Sensors and Actuators）. Concerning the wireless sensors network in the barn, the hardware designs for wireless sensor nodes and wireless sink nodes are given, and a network communication protocol suitable for data collection and transmission is also proposed. The practice shows that the new system based on those technologies has many notable advantages.
