无线通信的LED电子屏设计
资料介绍
传统的LED电子屏采用线缆传输数据,存在工程布线复杂、设备维护不方便和工程造价高等问题。为解决以上问题,本文设计了基于无线通信技术的LED电子屏系统。该系统由上位机、无线通信模块、单片机控制模块和LED点阵屏等4部分组成。采用VC#语言编写上位机控制界面,实现对要显示内容的文字编辑、取模、转换、发送等操作;采用nRF24L01射频通信模块,将上位机的字模数据以无线方式发送给LED点阵屏;LED点阵屏采用STC15W4K单片机为控制核心,实现对字模数据的接收,并控制点阵屏对文字进行左移、右移、静态等不同模式显示。该系统具有一定的市场应用价值。
Traditional LED electronic strip screen uses cable to transmit data, which has the problems of complex wiring, inconvenient equipment maintenance and high engineering cost. In order to solve the problems above, an LED electronic screen system based on wireless communication technology is designed. The system consists of four parts: upper computer, wireless communication module, single chip microcomputer control module and LED dot matrix screen. VC# language is used to write the upper computer control interface to display, edit, convert and send the text needed to display;NRF24L01 communication module is adopted to transmit the font data of the upper computer to the LED dot matrix screen in a wireless manner. STC15W4K single chip microcomputer is used as the control core of the LED dot matrix screen which can realize the receiving of font data, and control the dot matrix screen to move the text left, right, static and other different modes of display. The design has certain market application value.
