| Abstract: | In order to satisfy the needs of the public meteorological services,taking full advantage of the GPRS network for its wide coverage,real-time online,high quality communication,and low maintenance costs,a LED screen meteorological information broadcast system based on the GPRS network is designed and established.The structure and functions of the system,the hardware configuration,and the display process of the remote-control card for the LED screen are described.Three management programs in the system server and the terminal user programs are introduced.The method for converting vector-font characters to lattice characters is elaborated.The application of this system in practice is also discussed. |
