摘要
太阳能供电的交通信号控制器对光照的依赖性较大,基于MSP430超低功耗微控制芯片,设计了一种低成本、低功耗的倒计时交通信号控制器,并通过RS—232串口实现和上位机的联网通讯。实验结果表明:本系统控制信号灯稳定可靠,功耗超低,可用于太阳能供电的环境。
Traffic signal controller with solar energy extremely depends on illumination of the environment. A solution which is of low-cost and low-power consumption is proposed based on MSP430 embedded in count-down traffic signal controller, and the communication network is set up using RS-232 serial port. The experimental result indicates this reliable system and ultra-low power performance may be widely applied in solar energy controllers.
