【摘要】：随着社会经济和科技的不断进步,能源不足的问题已经成为当今社会的热点问题。我们国家已经把节约资源和保护环境定为基本国策,十八届三中全会也指出了要努力建立资源节约型的社会,最终实现人与自然可持续发展的目标。随着我国对教育事业的大力发展,校园建筑能耗作为社会能源消耗的一个缩影,消耗的能源日渐增加,为了积极响应十八大的号召,控制能源消耗,为社会建设贡献一份力量,校园能耗系统的开发与建立越显重要。建筑能耗是整个社会能源消耗的一个重要组成部分,特别是中国的大型公共建筑。对于整个社会来说,建筑节能是一个增加能源效率的有效方法。为了定位和控制,像超市、政府办公楼、医院和校园建筑等大型公共建筑的能耗状态,本文以校园能耗为切入点,设计了一个基于LabVIEW的校园能耗监控数据的采集系统。本论文针对校园能耗的基本情况设计了基于Lab VIEW的校园能耗监控数据采集系统,整个系统采用上位机与下位机协同工作,通过与下位机相互连接的传感器可判断室内温湿度、光强以及有没有人经过,并使用STM32开发板来实现对传感器的驱动与配置,从而实现对用电情况的数据采集及对能源消耗的控制,上位机以Lab VIEW这种图形化编程语言为平台,实时采集能耗数据并对其进行分析处理和展示。同时设计了基于互联网的终端显示,使得更多的人,在更大的范围内共享了传感器采集到的校园能耗使用数据及现状,使整个校园能耗采集监控系统的功能更加强大与完善。采用负载电流波形采集扩展板,能够实时监测与识别多种用电设备类型、功率、运行状态及预警;可以检测老化电器和校园违规电器的使用;并可以确定回路中使用高效节能电器产品比例,它为电器的负载状态做出准确的评估。此建筑能耗监测系统由能耗计量装置、数据采集器、网络通信设备构成,系统具有数据采集、数据存储、数据处理及分析、系统管理、系统运行状态监控和故障诊断功能,并能将各类数据及信息传送到上一级信息中心。本系统已在实验室条件下完成了调试运行,系统的采集速度、精度、控制速度等参数基本符合要求,为进一步搭建校园能耗数据采集系统的标准化平台奠定了基础。
[Abstract]:With the continuous progress of social economy and science and technology, the problem of energy shortage has become a hot issue in today's society. Our country has made saving resources and protecting the environment a basic national policy. The third Plenary session of the 18 CPC Central Committee also pointed out that we should strive to establish a resource-conserving society and finally realize the goal of sustainable development of man and nature. With the vigorous development of education in China, the energy consumption of campus buildings as a microcosm of social energy consumption. The amount of energy consumed is increasing day by day. In order to respond positively to the call of 18, to control energy consumption and contribute a part to social construction, The development and establishment of campus energy consumption system is becoming more and more important. Building energy consumption is an important part of the energy consumption of the whole society, especially the large public buildings in China. Building energy conservation is an effective way to increase energy efficiency. In order to locate and control the energy consumption of large public buildings such as supermarkets, government offices, hospitals and campus buildings, this paper takes the energy consumption on campus as the starting point. This paper designs a campus energy consumption monitoring data acquisition system based on LabVIEW. According to the basic situation of campus energy consumption, this paper designs a campus energy consumption monitoring data acquisition system based on LabVIEW. The whole system uses upper computer and lower computer to work together. The sensor connected with the lower computer can be used to determine the indoor temperature and humidity, the intensity of light and whether there is anyone passing by, and use the STM32 development board to realize the drive and configuration of the sensor. In order to realize the data acquisition and the control of energy consumption, the upper computer is based on Lab VIEW, a graphical programming language. At the same time, the terminal display based on the Internet is designed, so that more people can share the campus energy consumption data collected by the sensor and the present situation in a larger range. The function of the whole campus energy consumption acquisition and monitoring system is more powerful and perfect. The load current waveform acquisition and expansion board can be used to monitor and identify various types of power equipment, power, operation status and early warning in real time. It can detect the use of aging appliances and campus illegal appliances, and determine the proportion of high efficiency and energy saving electrical products used in the circuit, which makes an accurate assessment of the load state of electrical appliances. The building energy consumption monitoring system is made up of energy consumption metering devices, The system has the functions of data acquisition, data storage, data processing and analysis, system management, system running state monitoring and fault diagnosis. All kinds of data and information can be transmitted to the next information center. The system has been debugged and run under the condition of laboratory. The parameters of the system, such as acquisition speed, precision and control speed, basically meet the requirements. It lays a foundation for further building the standardization platform of campus energy consumption data acquisition system.
