基于FreeRTOS和MQTT的海洋监测网络框架

摘要

The framework of marine monitoring network based on real-time operating system is designed to monitor marine information in real-time and protect the marine environment. The design uses STM32 microcontroller application Free Real-Time Operating System(FreeRTOS), through a variety of sensors to collect data in the sea. And the FreeRTOS applies the MQTT to transmit data,to achieve real-time monitoring of the marine environment. Through the task design on FreeRTOS, the data collected by current meter and bathymeter are transmitted. Finally, the marine environment is monitored in real time.%设计基于实时操作系统的海洋监测网络框架,用于实时监测海洋信息,保护海洋环境.采用STM32单片机应用实时操作系统FreeRTOS实现,通过各种传感器在海下采集数据,并使用MQTT协议(消息队列遥测传输)进行数据传输,实时监测海洋环境.通过在FreeRTOS操作系统上进行任务设计,并对海流计、水深计采集的数据进行传输,最终实现海洋环境实时监测.
