气象预警信息显示终端设计

Design of Meteorological Early Warning Information Display Terminal

针对国家公共管理部门对气象预警的需求,设计了一种专业化的气象预警信息显示终端。系统融合SMS短信技术、GPRS无线通讯技术、语音合成技术、LED显示技术、嵌入式Linux系统和Qt软件设计等技术,实现了远程气象预警信息接收,信息显示与语音播报。详细描述了系统任务要求、软硬件设计方案及基于Linux的LCD接口驱动。实验和使用表明:信息内容显示清晰,通讯稳定可高,满足灾害预警要求。

Based on the national public administrations’ demand for meteorological early warning,a specialized meteorological early warning information display terminal is designed.With inte-grating SMS technology,GPRS wireless communication technology,speech synthesis technology,LED display technology,embedded Linux technology and Qt software designing technology,the system realizes receiving,displaying and broadcasting remote meteorological warning messages.The task requirement,hardware design,soft ideas and the LCD interface driver based on Linux are described in details.Experimental results show that the system displays images distinctly,communicates with the control center stably and meets the design requirement entirely.
