摘要
针对传统有线网络难以有效进行地震监测的问题,设计了基于无线传感器网络的地震监测系统。分析了该监测系统的结构,介绍了所设计的地震监测系统节点硬件组成和完成相关功能的软件系统。应用新一代AVR芯片灵活控制,及9XTend OEM强大的数据传输功能,简化了网络拓扑,能够适应复杂多变的环境,监测各种有线网络无法有效监测的地区,实现灾难预警与救助。
In view of the issue that the traditional cable networks can not undertake earthquake monitoring effectively, an earthquake monitoring system based on the wireless sensor networks is designed in this paper. The framework of monitoring system is analyzed, and the hardware structure of the nodes and software design of relevant functions are introduced. Based on flexible control functions of AVR microchip and powerful data transmission functions of 9XTend , the simplification of communication network topology is achieved. The system can be applied in the complex environments to monitor the areas where the cable networks can not work effectively and realize the catastrophe early warning and relief.
