本设计是基于高速公路LED隧道灯节能照明控制系统,本文研究目的是开发一种适用于隧道中间段的无线照明控制节点,以达到车进灯亮、车过灯灭、实时采集周围环境信息等效果。所采用的研究方法是通过单片无线收发芯片实现节点与上位机的无线通信,通过金属检测器传来的信号控制LED路灯,上位机以此信号来判断有无车辆以及车流量是否过大。根据已开发出的节点做实际测试,得出此节点模型已经达到其最初的研究目的,实现了系统中信息的采集与无线传输。通过本文提出的节点,能有效的减少无效照明,提高隧道运行的安全性,节省隧道运行成本。
This design is based on the highway LED tunnel light energy-saving lighting control system, the purpose of this paper is to develop a suitable wireless tunnel lighting control nodes in the middle section, in order to achieve the car into the light, the car off, real-time acquisition of environmental information and other effects . The research method adopted is to realize the wireless communication between the node and the host computer through a single chip of wireless transceiver chip. The LED street lamp is controlled by the signal from the metal detector, and the host computer uses this signal to judge whether the vehicle and the traffic flow are excessive. According to the actual test of the developed node, this node model has been reached its original research purpose, and the information collection and wireless transmission in the system have been achieved. Through the proposed node, it can effectively reduce the ineffective lighting, improve the safety of tunnel operation and save the tunnel operation cost.
