针对传统LED 显示屏投资大、远程控制功能差的缺点提出了基于电话网的远程控制
方案，设计了一套远程控制系统，通过该系统可随时更新显示内容。远程通信采用串口通信方式，采用的是目前管理方便，运行成本较低的通过公共电话网络进行远程控制，通过公用电话网连接控制器实现对LED 显示屏进行远程控制和显示内容的更新，从而实现计算机对每个显示屏进行远程控制并对显示内容进行更新。在系统的硬件上增加了调制解调器和一块全新设计专门用于连接调制解调器和LED 显示屏的接口板。

Abstract：The traditional LED display system has lots of defaults such as high value and low
function of long-range controlling. Aiming at this, the subject about precept of long-range
controlling system based on public telephone network was given. The system can control the
display screen distantly and can refresh the content at any time. To realize the long-range
controlling we adopt serial communication. It’s a method based on public telephone network, which cost low at present. It add a modem and a connecting board that connect the modem and LED display screen.
