【摘要】：近年来随着自动化技术、电子信息技术和计算机技术的快速发展,尤其是在物联网建设的推动下,住宅的智能化越来越受到人们的关注。本课题通过对基于物联网所构建的智能家居系统的工作原理和能耗的分析,认为要体现家居智能化,首先要解决家用电器的远程控制和节能控制,而空调能耗又较高,占家庭总能耗的约三分之一,所以在保证舒适的前提下降低空调能耗具有重要意义。通过分析家用空调传统控制方式高能耗的原因,研究了基于预测平均投票数(PMV)这种人体舒适度指标的控制方法。通过研究影响PMV值的六个参数变量,得到房间温度、房间湿度和室内空气流速对PMV值影响的曲线,并根据曲线具体变化规律,给出了节能控制算法。采用模糊控制理论设计了基于PMV值变化的模糊控制器,通过控制室内温度、湿度和室内空调出风口风速来间接控制PMV值稳定在舒适度范围之内,通过节能算法在夏冬季分别采用不同的控制方法实现节能。设计出一种应用于建筑设备物联网平台的无线红外转发器,采用对码学习和查询学习这两种方式对红外遥控指令进行学习,实现了无线红外转发器对任何品牌空调的远程控制并在建筑设备物联网环境下通过相关软硬件设计实现了家用空调的控制。设计实现了无线红外转发器与物联网节点之间的无线通信接口及数据传输协议,并将基于PMV值变化的模糊节能算法通过在建筑设备物联网节点配置及应用验证了其有效性。用户可以通过电脑、手机等终端在建筑设备物联网平台上设置空调相关控制参数,设置的控制参数通过建筑设备物联网节点最终下发到家中的无线红外转发器,从而实现对空调的节能控制。
[Abstract]:In recent years, along with the automation technology, the rapid development of electronic information technology and computer technology, especially in promoting the development of the Internet of things, intelligent residential more and more attention. The analysis of this topic through the intelligent Home Furnishing system built on the Internet of things based on the working principle and energy consumption, to reflect the Home Furnishing intelligence first of all, to solve the remote control and energy-saving control of household appliances, and air conditioning energy consumption is higher, accounting for about 1/3 of total household consumption, so it has important meaning to ensure comfort under the premise of reducing the energy consumption.
Through the analysis of the reasons for household air conditioning the traditional control method of high energy consumption, the number of predicted mean vote (PMV) control method based on the human comfort index. Through the study of six parameters that affect the value of the variable PMV, room temperature, humidity and air velocity in room PMV value curve, and according to the curve of concrete change control algorithm of energy saving are presented. Using the fuzzy control theory to design a fuzzy controller based on the change of PMV value, by controlling the indoor temperature, humidity and indoor air outlet velocity to indirectly control the stable PMV value within the comfort range, to achieve energy-saving control method through energy saving algorithm in summer and winter are different.
The design of a wireless infrared transponder used for building equipment networking platform, using the code of learning and inquiry learning of these two ways of learning infrared remote control instructions, realize remote control wireless infrared transponder for any brand of air conditioning and building equipment in the network environment through the relevant hardware and software design to achieve the control of household air conditioner.
The design and implementation of wireless communication interface and data transmission protocol between wireless infrared transponder and networking nodes, and through building equipment configuration and application of network nodes to verify the validity of the fuzzy algorithm based on such PMV value change. Users can use computer, hand machine terminal in the construction equipment networking platform is provided with air conditioning the control parameters, control parameters set by construction equipment networking nodes finally issued home wireless infrared transponder, so as to achieve energy-saving control of air-conditioning.
