基于以太网的文字声光警示系统设计

摘要

The text sound and light warning system based on Ethernet is designed .This system using UDP protocol to transmit alarm data ,has completed hardware design and software programming .In or‐der to make the system suitable for different applications ,the text and voice data is stored in the SD card and the file naming conventions are given in design‐time .The warning system can be triggered in manual or automatic ways to produce the appropriate warning information ,including the LED display showing , text warning information ,the voice system broadcasting warning voice and police lights flashing ,achie‐ving multiple reminders in visual and auditory .%在确定以UDP协议进行报警数据传输的基础上，研究其硬件设计及软件编程．为了使系统能够适用于不同的应用场合，设计时将文字及语音数据存储于SD卡中，并给出了SD卡中文件的命名规则．该警示系统在需要警示的情况下可人工操作或以自动触发方式产生．L ED显示屏显示文字警示信息，语音系统播放警示语音，警灯闪烁进行灯光警示，实现了视觉和听觉上的多重提醒等警示信息．
