智能照明系统的软件设计与实现

Software Design and Realization of Intelligent Lighting System

对于传统照明系统,通过开关控制一整块区域的灯具,且灯具不能调整亮度大小,整个区域灯具在无人时也会长明,这不仅降低灯具的使用寿命,还会造成极大的能源浪费。针对这一现状,阐述了一种基于灯联网的智能照明系统的软件设计与实现。热释电红外传感器探查灯具范围内是否有人,产生信号经过红外热释电处理芯片BISS0001处理后,转换为高低电平,接入新唐单片机引脚。系统采用一主多从的控制方式,从机利用2.4G无线收发器XN297L,将是否有人信号传入主机,主机整合所有从机信号,根据控制规则发送控制信号给每个从机,实现对灯具的亮度控制。

For traditional lighting systems,the lamps in a whole area are controlled by switches,and the brightness of the lamps cannot be adjusted.The lamps in the whole area will be bright when there is no one.This will not only reduce the service life of the lamps,but also cause great energy waste.In response to this situation,this paper describes the software design and implementation of an intelligent lighting system based on lamp networking.The pyroelectric infrared sensor detects whether there are people in the range of the lamp,and the generated signal is processed by the infrared pyroelectric processing chip BISS0001,converted to high and low levels,and connected to the Nuvoton MCU pin.The system adopts a control mode of one master and multiple slaves.The slave uses the 2.4 G wireless transceiver XN297 L to transmit the signal to the master.The master integrates all slave signals,and sends control signals to each slave according to the control rules to realize brightness control of lamps.
