摘　　要：针对多数煤矿井下信息显示系统落后的情况,设计了一种基于ARM7-LPC2131的低功耗电子显示屏,即地面数据信息或井下数据信息以通信方式传输至电子显示屏。电子显示屏中的LPC2131微控制器依据人的视觉瞬时特性,以动态扫描数码管的显示方式降低显示功耗,满足了本质安全型电源远距离带载的要求。该电子显示屏通过实际应用表明,能满足在复杂环境条件下各种数据信息的就地显示需求。For the existence of the more out date coal mine information display systems, a new low power consumption electronic display screen based on the ARM7-LPC2131 has been designed, which is transmitted the ground data information or underground data information to the electronic display via communication. Based on the visual instantaneous feature of human, the LPC213I Micro-controller in the electronic display reduce the power consumption with the display way of dynamic scanning digital tube, which also meets the requirements of intrinsically safe power supply long distance loading. The application of the electronic display shows that the new design enables a variety of data information to display locally under complicated conditions.
