摘　　要：为了解决有线监测系统布线复杂、易遭雷击、安装及维护成本高等缺陷,提出了一种基于无线传感器网络的粮情监测系统,并对系统架构、FFD/RFD节点硬件设计和网络通信协议做了详细介绍。在粮库现场,通过布置大量RFD节点采集实时信息,经多节点跳传将数据经基站节点传送到PC主机,从而实现了对粮情的远程实时监测,为管理决策提供了依据。实际运行结果表明,该系统具有安装简单、运行稳定可靠、抗干扰能力强等优点,可广泛应用于安防、环境监测等领域。To avoid defects of traditional wire surveillance systems such as complex wiring,vulnerable to lightening strike and high cost of installation and maintaining,a depot surveillance system based on wireless sensor network was proposed. System architecture,hardware design of FFD/RFD nodes and network communication protocol were studied in detail. A lot of RFD nodes were arranged in grain depots to capture real-time parameters,which were sent to a server computer by multi-hop wireless stations to telemonitor depot systems. Actual running results show that the wireless surveillance system takes advantage of easy installation, stable operation and high noise rejection, and it can be widely aoolied to safe-~uide and environment monitorinz systems.
