摘要
在对短距离声通信技术进行研究的基础上,以ARM为主处理器,设计了一种具有短距离声通信功能的传感器节点。该节点为这些环境中的无线传感器网络提供了一种不占用无线信道带宽、不受电磁干扰的通信方式。利用所设计的传感器节点实现了两节点间的短距离声通信,验证了短距离声通信的可行性。
On the basis of researching the short-distance acoustic communication technology, a kind of sensor node which has a function of short-range acoustic communication is designed, using that ARM as the main processor in this paper. The node pro- vides a communication mode which doesn't occupy the radio channel bandwidth and immunity from the electromagnetic interference in these environments. The short-range acoustic communication is achieved between two sensor nodes, which verifies that the short- range acoustic communication is feasible.
