基于无线节点的教学场所节电控制系统设计

Design of power saving control system for classroom based on wireless node

承担教学和自习功能的高校教室大都采用开放管理模式,时常会出现外部光照良好或空无一人时,室内照明灯处于全部开启状态,造成电能的浪费。针对高校教学场所电能浪费问题,该系统运用人体图像检测算法融合多种传感器的方法,设计出一套基于无线节点的高校教学场所节电控制系统。该系统分为OpenMV实时图像监测、灯具控制和无线通信3个部分,通过传感器来检测环境光照情况和室内各区域人员分布状况,从而调节灯具开关状态。实验结果表明,该系统具备良好的稳定性,可以达到精确控制灯具实现节能的目的。

Most of the university classrooms with the functions of teaching and self-study adopt the open management mode,and the external lighting is often good or empty while the indoor lights are all turned on,resulting in waste of electric energy.Aiming at the problem of power waste in university teaching places,this system uses image human detection algorithm and integrates various sensors to design a set of power saving control system based on wireless node.The system is divided into OpenMV real-time image monitoring part,lighting control part and wireless communication part,through the sensor to detect the environmental lighting and the distribution of personnel in each area of the room,so as to adjust the lighting switch state.The experimental results show that the system has good stability and can achieve the purpose of accurately controlling the luminaire to achieve energy saving.
