基于物联网的空调集中控制系统设计与实现

Design of System of Controlling Air Conditioner Based on the Internet of Things

为了将资源充分利用,成本降到最低,使用高性价比和低功耗的Cortex-M0作为控制每个分体空调的采集控制节点,它完成收发指令,控制空调运行和采集室内环境温度,湿度等一系列功能。而这些室内环境参数将通过RS485有线通讯方式和SI4432无线通讯方式传送给传输节点,最后由传输节点传送到以太网中上位机,上位机对得到的数据进行处理。此系统具有功耗低,通讯方式灵活,可靠性高的特点,满足对分体空调进行集中管理的要求。

In order to make full use of the resources and reduce the production cost to the lowest, this paper uses the Cortex-MO which has high performance-price ratio and low power consumption as a control node to take and send commands, adjust the temperature, wind direction and on and off, collect the temperature and humidity of the inner room. The information of the room will be sent to the transmitting node through the RS485 way and SI4432 wireless way. At last they will be sent to the host computer which is in the Etbemet by transmitting node, then the host computer handle the data. The feature of the system is low power consumption, flexible communication method, high reliability, and meet the requirement of the managing the split-type air conditioner.
