为了应对日益增长的城市供暖节能压力，解决由供暖引起的废气排放问题，本文设计并实现了一种基于物联网的温湿度与风速信息采集系统。介绍了系统的总体结构，设计完成了以 ARM 微处理器为核心、以 EC20模块为通信媒介、外接多路温湿度传感器和风速传感器的硬件电路和嵌入式软件程序。通过真实场景测试，系统实现了通过3G 网络实时、定时发送当地温湿度和风速数据至中心服务器的功能，控制中心根据设定的环境标准控制供暖锅炉调节供暖量，完全满足供暖调节的实际需求。同时，系统经过一定改进还可以应用到气象监测、档案管理、食品药品储存、工农业和交通等其它方面。尤其在物联网领域，本系统有着非常广泛的应用前景。实验结果证明了该系统的通用性和实用性。

The pressure of the energy conservation and air pollution caused by heating is extremely in-creasing currently.In order to solve these problems,a temperature,humidity and wind speed infor-mation acquisition system based on the Internet of Things (IoT)has been designed and achieved.This paper introduces the general structure of the system,in which the hardware circuit and the embedded software program are designed with the core of ARM microprocessor,the communication medium of the EC20 module,and connecting with several multiplex temperature and humidity sensors and ane-mometers.Verified by system testing in real environment,the system could transfer the data of tem-perature,humidity and wind speed to central server through 3G network automatically.Based on the standard of environment set in advance,the server center would control the heating adjustor to regu-late the heating supply.And these functions would completely meet our demand for intelligent heating control.Meanwhile,it could be improved somehow to be applied to numerous fields,such as meteoro-logical monitoring,archives administration,food and medicine storage,intelligent transportation,in-dustry and agriculture.Also, there would be a great application prospect for this intelligent monitoring system especially in the field of IoT.In practice,the universality and practicability of the system has been proved by experiment.
