摘要
介绍一种工程地震仪智能电源管理系统的设计与实现,该系统具有电压输入范围广、输出电压稳定、用户操作界面简洁以及低功耗等特点。系统的硬件设计是由DC/DC稳压电源电路、基于高速单片机C8051F320和24位高精度模数转换芯片LTC2449的电流检测电路以及LCD屏幕背光控制电路组成,软件部分主要由单片机的C语言程序和嵌入式Windows XP上的VC++用户界面程序组成。最终实现了一种能为工程地震仪提供稳定电源、实时检测电流并可以调节屏幕背光的智能电源管理系统。
The paper presents a kind of intelligent power management system used in engineering seismograph,which has features such as wide input range,stable output,self protection,simple user interface and low power consumption etc.The design of hardware in the system consists of power supply circuit based on power module,circuit based on high speed SCM C8051F320 and 24-digits high-precision ANALOG-TO-DIGITAL CONVERTER LTC2449,the LCD screen backlight power supply circuit.The design of software in the system consists of the C language program for SCM and VC user interface program based on Embed Windows XP.It eventually accomplishes a kind of intelligent power management system for engineering seismograph with stable power supplyment,real-time current detection and adjustment of screen back light.
