本文提出了一种基于无线传感器网络的高密度地震监测系统。为了实现高精度监测，我们开发了用于传感器节点和加速度传感器板的硬实时操作系统Pavenet OS。在Pavenet操作系统下，传感器节点的系统采样加速抖动小于0.3 us。与以前的系统相比，该系统为地震工程研究人员提供了以更低的成本和更高的节点密度测量地震期间结构振动的能力。
In this paper we present a high-density earthquake monitoring system using wireless sensor networks. For high-precision monitoring, we developed Pavenet OS, which is a hard-realtime operating system for sensor nodes, and acceleration sensor board. Sensor nodes of the system sample acceleration with less than 0.3 us jitter with Pavenet OS. The system provides earthquake engineering researchers the ability to measure vibrations of structures during earthquakes at less cost and higher node density than previous systems.
