摘要
针对学校教学楼照明系统电能浪费严重的现象,提出了一种节能控制的新方法。该方法以单片机为核心,根据传感器测得的光照度以及人数等信息,对室内灯具实现分片定时控制,系统设有RS-485总线,并选用上位机实现各教室照明系统的网络化管理,实现了智能控制、节约能源的目标。
In order to solve the serious electric energy waste problem of school building illumination system,a new method of energy conservation is proposed.The single chip is adopted as kernel part in the system and time slicing control on illumination equipments is performed based on place brightness and the population inside room detected by sensor.RS-485 bus is used in system and host computer is used to carry out network management on illumination system in the classrooms,thus can reach the goals of efficiency improvement and energy saving.
