随着照明技术的发展和人们生活水平的提高,照明不再是单纯的把灯点亮,还要考虑到管理智能化和操作简单化以及灵活性,特别是要满足楼宇特殊情况下照明。同时LED作为一种新的光源形式开始越来越广泛应用于应急照明及普通照明领域,LED光源具有寿命长,功耗低,安全低压供电等优点。随着超高亮度LED和大功率LED的开发成功,使LED开始应用于照明领域!该系统控制方式采用上位机控制,由上位机通过单片机来实现对楼宇房间照明设备的控制,同时可实现对楼宇房间照明设备工作状态的实时采集,并和上位机进行数据交换,单片机作为数据的采集和发送部分,系统中应急蓄电池的状态可在上位机上显示,便于检测系统中电池的性能状态。系统上位机操作界面用Visual Basic设计,界面操作简单,实用性强,上位机通过Mscomm串口控件和单片机进行数据通信。
With the development of lighting technology and the improvement of people’s living standards, lighting is no longer simply turning on the lights, but also taking into account the management intelligence and simplification of operation as well as the flexibility, in particular, to meet the lighting in special buildings. At the same time LED as a new form of light source began to be more and more widely used in emergency lighting and general lighting, LED light source has the advantages of long life, low power consumption, safe low voltage power supply. With the successful development of ultra-high brightness LED and high-power LED, the LED begins to be applied to the field of lighting! The system control mode adopts the host computer control, and the upper computer realizes the control of the building room lighting device by the single chip microcomputer, Building room lighting real-time collection of working conditions and data exchange with the host computer, the microcontroller as part of data collection and transmission, the system state of emergency batteries can be displayed on the host computer to facilitate the detection of battery performance status in the system. System PC operating interface with Visual Basic design, the interface is simple, practical, PC through the Mscomm serial port control and single-chip data communication.
