【摘要】：近年来,随着物联网、通信与传感器等技术快速发展,基于传感器设计的智能网络平台已经广泛地应用到人们的生活、生产中。传统照明系统存在浪费能源、布线繁复、可扩展性低、人工管理等问题。另外,随着用眼时间的增加,人们对照明系统提出了新的要求,即新型照明系统需要有节能、护眼、网络化、智能化等功能。因此,如何将网络技术、感知技术应用于照明系统成为人们研究的新方向。在学校的照明系统中,许多照明设备会因为人为因素、自然因素被破坏,造成系统异常。为了解决该问题,本文设计基于异常感知的教室照明控制系统,并取得了如下成果：(1)根据照明系统中的需求分析和功能分析,设计了教室照明控制系统的总体方案。在该方案中,针对系统中存在资源浪费、管理效率低等问题,提出使用传感器监控用电设备的设计方法；针对传统照明系统扩展性差的问题引出了传感网络的解决方案；针对节点故障引起网络拓扑变化的问题,引入了自动组网的组网方法。(2)针对照明系统的特性,设计了用于监控用电设备的传感节点。该传感节点具有通信与感知的功能。利用该传感节点可以感知用电设备的温度、用电量以及教室的人员情况。(3)针对教室中,照明设备会受到各种破坏形成照明系统异常的问题,提出了基于聚类的异常事件感知算法,并把该算法应用到教室照明控制系统。分析了教室照明控制系统中常见的异常,取得了异常的数据。对正常、异常的数据进行了训练,利用训练的结果来检测系统是否有异常。在实际的教室中实现了基于异常感知的教室照明控制系统,并安装于教室内进行了实验。通过系统的实际测试以及仿真实验可知,该系统可以达到预期的目标。
[Abstract]:In recent years, with the rapid development of Internet of things, communication and sensor technology, the intelligent network platform based on sensor design has been widely used in people's life and production. There are some problems in traditional lighting system, such as waste of energy, complicated wiring, low expansibility, manual management and so on. In addition, with the increase of eye use time, people put forward new requirements for lighting system, that is, the new lighting system needs to have the functions of energy saving, eye protection, networking, intelligence and so on. Therefore, how to apply network technology and perceptual technology to lighting system has become a new research direction. In the school lighting system, many lighting equipment will be destroyed because of human factors and natural factors, resulting in system anomalies. In order to solve this problem, this paper designs a classroom lighting control system based on abnormal perception, and achieves the following results: (1) according to the requirement analysis and function analysis of the lighting system, the overall scheme of the classroom lighting control system is designed. In this scheme, aiming at the problems of waste of resources and low management efficiency in the system, the design method of using sensor to monitor electrical equipment is put forward, and the solution of sensor network is introduced to solve the problem of poor expansibility of traditional lighting system. In order to solve the problem of network topology change caused by node fault, an automatic networking method is introduced. (2) according to the characteristics of lighting system, a sensor node for monitoring electrical equipment is designed. The sensor node has the function of communication and perception. The sensor node can be used to sense the temperature, electricity consumption and classroom personnel of the electrical equipment. (3) in order to solve the problem that the lighting equipment will be destroyed to form the abnormal lighting system in the classroom, an abnormal event sensing algorithm based on clustering is proposed, and the algorithm is applied to the classroom lighting control system. The common anomalies in classroom lighting control system are analyzed, and the abnormal data are obtained. The normal and abnormal data are trained, and the results of training are used to detect whether there are anomalies in the system. The classroom lighting control system based on abnormal perception is realized in the actual classroom, and the experiment is carried out in the classroom. Through the actual test and simulation experiment of the system, it can be seen that the system can achieve the expected goal.
