基于无线传感器网络的房屋健康监测系统设计

摘要

由于通过有线传输传感器数据来监测现有房屋安全的方式花费高,布线繁琐,线路后期维护成本高等原因,在此以ZigBee技术为平台,设计无线传感器网络传输传感器数据的监测系统.此系统包括协调器节点、路由器节点和无线传感器节点,其中节点硬件包括主电路模块、电源模块和传感器模块.软件设计是基于ZigBee技术的Z?Stack协议栈.对节点间的传输距离和数据传输准确性以及整个网络在实际建筑物中的可行性进行了测试.测试结果表明,设计的无线传感器网络系统通过路由器进行数据跳传可以准确地传输数据,并能够在实际中应用.%Since there exist problems of high cost,complicated wire routing and high expenses of later-stage wire mainte-nance in the mode of using wire transmission sensor data to monitor the existing building safety,a sensor data monitoring system based on wireless sensor network transmission was designed taking ZigBee technology as the platform. The system consists of co-ordinator node,router node,and wireless sensor node. The nodes′ hardware is composed of main circuit module,power module, and sensor module. The software design is based on the Z-stack protocol stack of Zigbee technology. The transmission distance and data transmission accuracy between nodes and the feasibility of the whole network in real building were tested. The results show that the designed wireless sensor network system can transmit data accurately by means of data hop transmission via the router,and can be applied in practice.
