教室无线点阵显示系统的研究

主要介绍了教室无线点阵显示系统设计的具体方案。其适用于教室等多场所、多地域设置点阵屏,并要求同时即时获得信息的场合。无线点阵显示系统由上位机管理模块、无线发射与接收模块、LED点阵显示模块组成。上位机将信息通过RS232串口模块发送给无线发射模块,数据通过nRF905模块进行调制,并通过天线将数据发出。无线接收模块接收数据后通过I2C总线存储,再从24C02中取出数据通过I2C发送到相应点阵显示模块进行显示。

Research on CIassroom WireIess Dot Matrix DispIay System

This paper introduces the classroom the concrete scheme of wireless dot matrix display system design.It is applicable to many places,such as the classroom more regional Settings lattice screen,and at the same time instant access to information required.Wireless dot matrix display system consists of PC management module,wireless transmitting and receiving modules,LED dot matrix display module.PC through RS232 serial port module the information sent to the wireless transmitting module.Data through the nRF905 modulation module,and through the antenna will be issued data.
