手持式终端设备中电源监测技术研究与实现

Study and Implementation of Power-Monitoring Technology for Hand-Hold Terminal

根据嵌入式系统内置电源维护方式简化、降低制造和使用成本的具体要求,详细介绍了基于串连式可充电电池组的电源监测技术。在完成监测系统原理分析及电路设计的基础上,进行了具体的电路搭制、调试和Linux环境下驱动程序编写,并结合相应的显示需求而进一步实现了Qt/Embedded应用程序编写和植入Qtopia的方法。实现了手持式嵌入式系统中的电源的精确可视化监测。

Based on the requirement of simplifying the maintenance of battery- power system inside the embedded system and reducing the relative expenses on it, introduces the power monitoring method of series- connected rechargeable battery pack in detail. The principle of monitoring system is carefully studied, and the corresponding circuits are implemented as well. Then, the relative Linux drivers are discussed, and written according to the demand of displaying the windows on LCD, which shown the working status of batteries, by using the Qt/Embedded application program and mounted it into Qtopia. Implemented the power-monitoring technology for hand- hold embedded system.
