时段式教室照明节能控制器的设计

Design of Auto-Timed Energy-saving Lighting Controller for Classrooms

介绍了一种可预设定时间的照明节能控制器的研发.该控制器硬件以AT98S52单片机为控制芯片,DS12C887时钟芯片为时钟计时,软件采用MCS-51单片机汇编语言,可在每天预定的3个时间段内对教室、车间等公共场合的照明灯进行集中控制,实现在该3个时段内当房间无人时关断照明,房间有人时开启照明并适时延长照明时间的节能控制.该控制器时钟运行不受市电停电影响,时钟年误差小于10 min.

This article introduced the research and development of an auto-timed lighting controller which uses AT98S52 as the controller chip,clock chip of DS12C887 as the clock time,and MCS-51 assembly language as the software.A three-hour centralized control is available for classrooms and workshops every day in which the lighting is switched off for a vacant room,and switched on when there is people around.With an annual clock error less than ten minutes,it has achieved the expected results.
