摘　　要：LED 线阵显示装置, 分为 LED 线性旋转显示主机和图文录入器两部分。主机用直流电机带动由红绿 LED 组成的线阵旋转, 同时线阵按照时序依次切换显示状态, 在固定区域利用视觉暂留效果形成 16×16 点阵, 用以显示图文;图文录入器用 HMI 触控屏作为人机交互界面, 实现图文录入和回放功能。主机与图文录入器通过无线通信方式进行信息交互,可由图文录入器控制主机切换不同工作任务, 以及改变线阵显示内容。The LED linear array display device is divided into two parts:the one is the main unit used to display content,and the other one is used to input the contents.The main unit is driven by a DC motor to rotate the linear array composed by red and green light emitting diodes.At the same time,the 16×16 dot matrix that switching the display state according to the time sequence on the main unit displays pictures and texts in the fixed area,by using the visual temporary effect.The HMI touch screen is used as human machine interface to realize the function that input and playback pictures and texts.The two parts of the device communicate with each other through wireless communication.The image and text input controller can control the main unit to switch different tasks and change the content of linear array displayed.
