摘要
本文基于FreeRTOS实时操作系统开发了一款物联网温度监测系统,包含了STM32F103单片机控制核心、温度监测模组、通信模组、降压模组。该系统利用FreeRTOS操作系统开发,利用消息队列监控串口进行平衡读写,能够保证系统的持续稳定运行;选用高精度温度探头,使得测量温度数据更为精确;利用MQTT协议,将数据上传至云端,用户可在移动端进行实时监控。
This paper develops an IoT temperature monitoring system based on FreeRTOS real-time operating system,including STM32F103 MCU control core,temperature monitoring module,communication module and step-down module.The development of FreeRTOS operating system and the balanced reading and writing of message queue monitoring serial port can ensure the continuous and stable operation of the system.High precision temperature probe is selected to make the measured temperature data more accurate.Using MQTT protocol,the data is uploaded to the cloud,and users can conduct real-time monitoring on the mobile terminal.
