Design of WSN Data Acquisition System under Linear Space

线性空间下基于IEEE 802.15.4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温湿度及光照信息采集系统,并具体设计了单个节点。实际搭建线性网络平台,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线性空间下的传播性能,测试了节点间接收信号强度指示(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 which based on IEEE 802. 15.4 has a wide range of application under the restricted linear space. In this paper, the temperature, humidity and light information acquisition system are designed based on Wireless Sensor Network （WSN）. The linear network platform is used to gather and analysis data collect by each node. Further more, the spread of the wireless signal in restricted linear space theory is studied. At the same time, the Received Signal Strength Indication（RSSI） and packet loss rate of data transmission between nodes are tested. The experimental results prove that the system has excellent performance and practical value.
