为了提高整个无线传感器网络的性能,提出了一种基于Zigbee+WiFi混合型协议的无线传感器网络监控系统,即在资源有限的簇内采用功耗、成本、传输速率较低的Zigbee协议进行非视频通信;而簇间的通信则采用带宽较宽的高速率传输协议WiFi实现音视频通信。通过选择合适的传感器,结合CC2530主控芯片,并以Linux嵌入式为开发环境,实现井上对井下作业和人员的远程监控。
In order to improve the performance of the whole wireless sensor network, based on the mixed protocol Zigbee and WiFi, a new wireless sensor network monitoring system is proposed in this paper. Within the limited resources of cluster, the low power consumption, low cost, low transmission rate of Zigbee protocol is used to support the non-video communications; and communications between the clusters, the use of the wide bandwidth high rate transmission protocol of WiFi can realize the audio and video communications. By selecting the appropriate sensors, combined WiFi CC2530 control chip.And for Linux embedded development environment, the system can achieve unhook remote monitoring of borehole operation and staff.
