Cortex-M3的生态物联网数据采集分站设计

IOT Data Acquisition Substation for forestry ecology monitor Based on Cortex-M3

以Cortex-M3处理器LM3S811为核心,设计了面向森林生态监测的物联网数据采集终端分站系统。通过单总线数字式温湿度传感器、烟雾传感器、CO2传感器和环境光亮度传感器分别采集温度、湿度、可燃性颗粒物、CO2含量和光照等与林木生态相关的环境信息和林场防火的相关信息。由LM3S811处理器处理并添加分站ID和校验码后,采用无线模块传送给服务器。

The IOT（Internet of things）data acquisition substation for forestry ecology monitor is proposed, which employs the Cortex- M3 processor as the CPU. Digital temperature humidity sensor, smoke sensor, C（）2 sensor and digital luminance sensor are employed to acquire the environment information which is related with forestry ecology. Then the sensors data are collected by LM3S811 and ID of substation is added to data packet. Further more, LM3SSll transmits the data packet to servers using RF module.
