针对矿井挖掘延伸容易对数据无线传输和网络生命周期造成较大影响的现状,从均衡网络能耗的角度出发,设计了一种基于SimpliciTI网络协议的井下无线监测系统。首先选择CClll0芯片作为节点核心,在SimpliciTI网络协议栈的基础上组建了无线传感器自组织网络,然后分析和改进了SimpliciTI网络跳频机制,针对各节点频率跳变的盲目性,提出了一种基于信道预测的网络接入机制。
In view of the current situation that mining extension easily affects the data wireless transmission and network life cycle greatly, this paper designs a downhole wireless monitoring system based on SimpliciTI network protocol from the perspective of energy consumption of the network. Firstly, the CClll0 chip is selected as the core of the node. Based on the SimpliciTI network protocol stack, a wireless sensor self-organizing network is established. Then the frequency hopping mechanism of SimpliciTI network is analyzed and improved. Aiming at the blindness of frequency hopping of each node, Channel prediction network access mechanism.
