【摘要】：随着经济社会的发展和城市化进程的推进,我国建筑能耗呈现刚性增长趋势。从全生命周期方面来看,建筑能耗占全社会总能耗的1/3,甚至有继续增长趋势。据统计,在建筑能耗中,建筑用电能耗约占总能耗58%,采暖能耗约占总能耗的37%,而建筑材料能耗占到不足5%。因此,建筑节能用电作为建筑节能的一个重要方面,如何利用现有的计算机技术、嵌入式技术、通信手段和数据处理技术等方法,建立并完善一个效率高、成本低的、智能化的建筑智能用电系统以减少建筑用电能耗问题已成为热点。在信息领域,物联网技术作为研究热点,物联网对“物～物”、“人～物”的信息交互、处理和应用提供了解决方法,在世界各国国家战略中具有重要地位,基于物联网的建筑智能用电不仅有益于建筑节能用电效果的提高,同时也是建筑智能化标准的提高。基于此,本文提出了一种基于物联网的建筑智能用电系统。首先,论文综述了建筑智能用电系统总体方案的设计和物联网技术。ZigBee作为一种满足传感器和设备控制的传输要求的无线网络,非常适合楼宇自动化、家庭自动化、智能能源管理等领域的无线传感环境。其次,设计了一套基于物联网的建筑智能用电系统平台。介绍了系统所需的技术架构和工作原理,包括无线环境参数监测节点、无线智能开关、无线智能插座、房间控制器、ZigBee模块等智能平台的设计；同时,详细分析了智能网关中TCP/IP协议栈LwIP的移植,并描述了智能网关的工作流程,解决了ZigBee无线网络和LAN网络对接问题。最后,依托此建筑智能用电系统框架,提出了一种基于BP的神经网络专家系统控制算法模型。此控制算法模型通过拥有神经网络的自学习和自适应能力的专家系统来实现对这些数据的分析、优化,得到精确的输出,控制相应的电气设备比如空调机、风鼓机、电灯、加湿器等电器改善环境参数,从而达到我们要求的控制策略目标。在上述算法的基础上,开发设计了一套基于C/S架构的建筑智能用电监控系统,用户可以通过此软.查看当前建筑环境参数、智能设备信息及用电情况,同时根据建筑环境参数及用电信息,自动控制智能设备,实现建筑智能用电。
[Abstract]:With the development of economy and society and the development of urbanization, the energy consumption of buildings in China is increasing rigidly. From the whole life cycle point of view, building energy consumption accounts for one third of the total energy consumption of the whole society, and even continues to increase. According to statistics, in building energy consumption, building energy consumption accounts for about 58 percent of the total energy consumption, heating energy consumption accounts for about 37 percent of the total energy consumption, and building materials energy consumption accounts for less than 5 percent. Therefore, as an important aspect of building energy conservation, how to use the existing computer technology, embedded technology, communication means and data processing technology to establish and improve a high efficiency and low cost, Intelligent building intelligent power system to reduce building energy consumption has become a hot issue. In the field of information, Internet of things (IOT) technology is a hot research topic. It provides a solution to the information exchange, processing and application of "matter" and "human", and plays an important role in the national strategy of various countries in the world. Building intelligent power consumption based on Internet of things is not only beneficial to the improvement of building energy efficiency, but also to the improvement of building intelligence standard. Based on this, a building intelligent power system based on the Internet of things is proposed in this paper. First of all, the paper summarizes the design of building intelligent power system and the Internet of things technology. ZigBee, as a wireless network that meets the requirements of sensor and device control, is very suitable for building automation and home automation. Intelligent energy management and other areas of wireless sensor environment. Secondly, a building intelligent power system platform based on Internet of things is designed. This paper introduces the technical framework and working principle of the system, including the design of intelligent platform such as wireless environment parameter monitoring node, wireless intelligent switch, wireless intelligent socket, room controller and ZigBee module. The transplantation of TCP/IP protocol stack LwIP in intelligent gateway is analyzed in detail, and the workflow of intelligent gateway is described, which solves the problem of ZigBee wireless network and LAN network docking. Finally, a neural network expert system control algorithm model based on BP is proposed. This control algorithm model realizes the analysis of these data, optimizes, obtains the accurate output through the expert system which has the neural network self-learning and adaptive ability, controls the corresponding electrical equipment such as the air conditioner, the wind drum machine, the electric light, Humidifier and other appliances improve environmental parameters to achieve our desired control strategy objectives. Based on the above algorithms, a building intelligent power monitoring system based on C / S architecture is developed. At the same time, according to the building environment parameters and power consumption information, the intelligent equipment can be automatically controlled to realize the intelligent building power consumption.
