中文摘要:
      以S7 200系列PLC和白色大功率LED灯为基础,针对隧道内的特点,设计了隧道内的智能照明控制系统,以实现隧道内的照明自动化控制。洞口视频车辆检测器用来检测车辆的速度和车次,亮度检测器主要用来检测白天的光照强度,PLC根据视频车辆检测器和亮度检测器采集的信号,经过计算,向隧道灯组(LED灯组)输出亮度命令,进行无极调控。PLC与上位机之间通过以太网进行通信。实验结果证明,此设计与传统高压钠灯供电系统相比可大大节省隧道内耗电量。在理论上,设计可适用于各种具有即点即亮特性的光源以及各种长度的隧道。
英文摘要:
      This design is based on S7 200 series PLC and white high power LED lamp. According to the characteristics of the tunnel, the intelligent lighting control system is designed. The video vehicle detector for detecting vehicle speed and vehicle, brightness detector is mainly used to detect the light intensity, according to the PLC video vehicle detector and brightness detector signal acquisition, after calculation, to the tunnel lamp group (LED lamp group) output brightness command for stepless regulation. The communication mode between PLC and PC is Ethernet. The experimental results show that this design can greatly save tunnel friction power. In theory, the design can be applied to all kinds of light source and the length of the tunnel.
