【摘要】：目前国内大部分高等院校教室的照明设备都采用由学生自主管理或者由专人管理的模式,经常出现白天长明灯,无人也开灯,一人灯全开等浪费现象。为响应国家深入推进节能减排工作的号召,将建设节约型校园的工作做实、做细、做深,研究实现高校教室的照明节能控制系统具有重要的应用价值。本文针对目前高校教室照明电能浪费严重的问题,设计并实现了一种面向高校教室的照明节能控制系统。该系统主要包含若干教室控制单元、校园网通信系统和控制中心。其中,教室控制单元由多类终端节点和单元控制器组成,终端节点通过2.4G无线射频通信将采集的数据发送到单元控制器,单元控制器在分析处理后将指令传送到终端节点使其执行开关灯具的动作。教室单元控制器与控制中心之间依托学校局域网进行通信,采用有线总线分布方式,实现总线数据信号与教室单元控制器信号的交互,稳定可靠且避免了重新布线的麻烦。控制中心通过可视化界面实现对各个教室的状态监测、实时控制与信息管理。对教室采用分区域控制的方法,克服了因学生座次分散时打开多盏灯的问题;采用多模式的控制策略,进一步满足了教室多用途的需要,使系统运行更加灵活人性化;引入了人数阈值,依据教室用途和人数多少控制灯具的开关数量;引入了光强的开启下限值与关闭上限值,有效避免了在光照不足开灯之后因光强大于下限值而造成频繁开关灯的系统紊乱问题。本系统硬件部分主要设计了由各类终端节点、教室单元控制器组成的教室控制单元。整个系统低功耗、低成本,操作简单且实用性较强,克服了人工管理的不足,做到了精细化节能,节能效果显著。
[Abstract]:At present, most of the lighting equipments in the classrooms of colleges and universities in our country adopt the mode of independent management by the students or the management by the special personnel. It often appears the waste phenomenon such as long light during the day, no one turning on the light, and all the lights of one person being turned on. In response to the call of the country to promote energy conservation and emission reduction, it is of great value to study and realize the lighting energy-saving control system of university classrooms. Aiming at the serious problem of lighting energy waste in university classroom, this paper designs and implements a kind of lighting energy saving control system for university classroom. The system includes several classroom control units, campus network communication system and control center. The classroom control unit is composed of multi-class terminal nodes and unit controllers. The terminal nodes transmit the collected data to the unit controller through 2.4G wireless radio frequency communication. The unit controller transmits the instruction to the terminal node after the analysis and processing to perform the action of the switch lamp. The communication between the classroom unit controller and the control center depends on the school local area network. The communication between the bus data signal and the classroom unit controller signal is realized by using the wired bus distribution mode, which is stable and reliable and avoids the trouble of rewiring. The control center realizes the state monitoring, real-time control and information management of each classroom through visual interface. The method of sub-area control is adopted to overcome the problem of turning on more than one lamp when the students' seats are scattered, and the multi-mode control strategy is adopted to further meet the multi-purpose needs of the classroom and to make the system run more flexibly and humanized. The threshold of number is introduced to control the number of switches according to the use of classroom and the number of people. The opening and closing upper limit values of light intensity are introduced to effectively avoid the system disturbance of frequent switching lights caused by light intensity greater than the lower limit when the light is insufficient to turn on the light. The hardware part of this system mainly designs the classroom control unit which consists of all kinds of terminal nodes and classroom unit controller. The whole system has the advantages of low power consumption, low cost, simple operation and strong practicability.
