摘要
针对目前井下监控系统采用单一协议兼顾不到合理利用网络资源、降低能耗、提高传输速率等问题,设计了一种基于zigbee+wifi混合型协议的无线传感器网络监控系统。该系统采用zigbee协议传输非视频数据,通过分簇式链状无线网络上传到地面监控中心;采用wifi协议上传音视频信息,两者的结合最大限度的降低了单一wifi协议所带来的高成本、高功耗以及单一zigbee协议传输音视频数据实时性差的问题。实际应用效果表明,该混合型协议无线网络监控系统大大提高了系统的可靠性和安全性。
According to a single protocol applied to the present underground monitoring and control system could not consider the rational utilization of the network resources, the reduction of the energy consumption, the improvement of the transmission rate and other problems, a monitoring and control system of the wireless sensor network was designed based on the zigbee ＋ wifi mixed type protocol. Non video data of the system would be transmitted with the zigbee protocol and could be transmitted to the surface ground monitoring and control center with the cluster type chain wireless network. The video and audio information could be transmitted with the wifi protocol. The mixed zigbee and wifi could uttermost reduce a high cost and high power consumption of the single wifi and the real time difference problem of the video and audio data transmitted with the single zigbee protocol. The actual application results showed that the monitoring and control system with the stated mixed protocol wireless network could highly improve the reliability and safety of the system.
