A wireless sensor networks(WSNs)based on Wi-Fi technology is researched for ground dynamic pressure test of explosion 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 16 Mbyte
wireless communication rate of 1Mbps and network coverage of 300m.
