手机供电过程中的智能化控制

Intelligent Control of Cell Phone Power Supplying

手机的工作过程也是电池的放电过程,在该过程中实施智能化控制,对延长手机待机时间、改善通话质量、提高使用效率、延缓电池的使用寿命具有决定性的作用。结合GSM手机电池供电的典型电路,对放电时的断续供电、脉冲供电、动态变压供电和低电量识别关机等新型供电方式中的智能化控制做了理论上的论述和剖析;解决了以往连续供电所带来的能耗大、效率低的问题,对进一步改进和优化手机电路有一定的指导作用和参考价值。

The work process of cell phone is also the process of discharge of battery, the intelligent control of the process plays a decisive role in the extension of standby time improving the quality of calling increase efficiency and extending battery life and so on. Based on the typical circuit in GSM cell phone,this paper gives theoretical naration and analysis of intermittent power supply, pulse power supply,dynamic variable-voltage power supply, low power recognition shutdown, etc. It solves the problem of large power consumption and low efficiency. It has the function of guiding and value of reference for further improving and optimizing the circuit of mobile phones.
