摘　　要：针对爆炸场地面动态压力测试,研究了基于Wi-Fi技术的无线传感器网络。设计了基于事件触发的地面测试无线传感器节点,分布式节点在系统监控和数据传输时自动连入网络,可降低功耗。通过定向微带天线和增益放大器改善地面效应对天线性能的影响,实现远距离的无线通信。爆炸现场试验结果表明:此无线传感器网络实现了2 Msps信号采集、16 Mbyte单节点数据存储,1 Mbps无线通信速率和300 m的网络覆盖。A wireless sensor networks （WSNs） based on Wi-Fi technology is researched for ground dynamic pressure test of xplosion field. The wireless sensor node for ground test based on event-triggered mode is designed,the distributed nodes are automatically connected to the network while system monitoring and data transmission, which reduces power consumption. Directional micro-strip antenna and gain amplifier are employed to improve the influence of ground on the antenna performance, which results in long-distance wireless communication. The explosion scene experimental result indicates that the proposed WSNs realizes signal acquisition of 2Msps, single-node data storage of lfi Mbyte, wireless communication rate of 1Mbps and network coverage of 300 m.
