摘　　要：目前矿用声光语音报警装置大多采用发光二极管焊接成字显示,显示内容死板,功能单一,制作既费时又费力而且控制电路多采用模拟电路或单片机,整个电路的调试比较麻烦,可靠性和实时性很难得到保证。针对这种情况,提出一种由SD卡存储显示内容,ARM Cortex-M3内核的STM32F103作为微控制器、LED屏显示的设计方案,使得显示内容灵活多变、丰富多彩,功能完善。充分发挥了STM32F103的高性能优势和在线调试功能,实现了大屏LED的无闪烁高亮度显示。最后再介绍电源系统的组成。Currently,most of the voice alarm sound and light welded into a word with diode display in mining products ,display rigid ,single function ,making time-consuming and laborious. And the control circuit using analog circuits or multi-chip. The entire circuit debugging more trouble ,reliability and real-time very difficult to guarantee. In view of this situation,this paper presents a display content from the SD card storage ARM Cortex-M3 STM32F103 as a micro-controller. The design of LED screen makes flexible display;rich and colorful,functional. Give full play to the STM32F103 performance advantages and online debugging. Achieve a large-screen flicker-free high-brightness LED display. Final continue introduce the compose of the power.
