摘　　要：限定空间下基于IEEE802.15.4的无线通信具有广泛的应用价值.设计了一套基于无线传感器网络的信息采集系统,并在限定空间下研究了该系统的属性.首先利用该平台收集每个节点采集的数据并分析,同时进一步研究了无线信号在限定空间下的传播性能,测试了节点间接收信号强度指示(ReceivedSignal Strength Indicator,RSSI)与数据传输丢包率.试验证明:该系统性能优良,具有很好的现实应用价值.Wireless communication based IEEE 802.15.4 has a wide range of application based on the restricted space.The information acquisition system was designed based on wireless sensor network,and study properties of system in the restricted space.Data collected by each node was analyzed,and the spread performance of the wireless signal in the restricted space was studied.At the same time,the RSSI and packet loss rate of data transmission between nodes was tested.The experiment proves that the system has excellent performance and practical value.
