摘要
波浪传感器长期工作于表面漂流浮标中,用于监测波浪的高度、周期、方向等特征。论文采用STM32F4为控制核心,设计了基于加速度原理的波浪传感系统。硬件采用高精度的惯性传感单元对姿态和加速度进行采集,使用SD卡作为数据存储模块、ESP8266作为无线通讯模块。在RT-Thread实时操作系统框架下编写了数据采集转换、波浪特征值计算、无线发送等线程,具有稳定可靠、实时性强的优点。并通过正弦模拟和定向水流试验验证了传感器的准确性。
Wave sensors working in surface drift buoys for a long time to monitor the height,period,direction,and other characteristics of waves.This article uses STM32F4 as the control core and designs a wave sensing system based on the principle of acceleration.The hardware adopts high-precision inertial sensing units to collect attitude and acceleration,using SD cards as data storage modules and ESP8266 as wireless communication modules.This paper has written threads for data collection and conversion,wave feature value calculation,wireless transmission under the RT-Thread real-time operating system framework,which has the advantages of stability,reliability,and strong real-time performance.The accuracy of the sensor is verified through sinusoidal simulation and directional water flow experiments.
