针对当前LED显示系统显示颜色和图形样式单一、布线复杂、不支持三色LED灯等问题,设计基于物联网技术的三色LED灯点阵显示系统.该系统主要由单列灯控制器、网关控制器和终端控制器组成.其中单列灯控制器负责对三色LED灯亮暗及多个显示颜色的控制.网关控制器向上通过WIFI模块同终端控制器通信,向下通过485串口与单列灯控制器实现通信,传输每个单列灯控制器的控制命令和状态信息.终端控制器实现控制命令的发送,提供人机交互的界面.试验结果表明:该系统可实现由汉字、英文、阿拉伯数字等组成的多种图形的智能显示,具有一定的应用价值.
In view of the current LED display system display color and graphic style of a single, complex wiring, does not support the three-color LED lights and other issues, the design of the three-color LED light dot matrix display system based on the Internet of things. The system is mainly composed of a single lamp controller, gateway control And terminal controller which consists of a single light controller is responsible for three-color LED light and dark multi-display color control gateway controller upward through the WIFI module with the terminal controller communication, down through the 485 serial port and a single lamp controller Which can realize the communication and transmit the control commands and status information of each single-column lamp controller.The terminal controller can send the control commands and provide the interface of human-computer interaction.The experimental results show that the system can be composed of Chinese characters, English, Arabic numerals and so on The intelligent display of a variety of graphics, has a certain application value.
