CN101267613B - A power-saving method for GPS mobile phone - Google Patents

Abstract

The invention discloses a method for saving electric power of a GPS mobile telephone, which comprises that, a vibration detection module is added in a GPS mobile telephone composed of a mobile telephone core module, a GPS module and a battery, mechanical vibration of the mobile telephone is detected by the vibration detection module, when the vibration detection module does not detect a vibration signal, that means, the position of the mobile telephone is not changed, the mobile telephone core module can control the GPS module into an electric power-saving state; otherwise, when the vibration detection module detects a vibration signal, that means, the position of the mobile telephone is changed, the mobile telephone core module can control the GPS module out of the electric power-saving state. In this way, the GPS mobile telephone can enter the electric power-saving state even in a standby state, the standby power consumption of the GPS mobile telephone is approach to the standby power consumption of a traditional mobile telephone, thereby prolonging the standby time of the GPS mobile telephone.

Description

The method of a kind of GPS mobile phone power saving

Technical field

The present invention relates to the mobile phone technique field, particularly relate to the method for a kind of GPS mobile phone power saving.

Background technology

Along with the GPS technology the navigation and Position Tracking aspect promoting the use of; Meanwhile mobile phone is also more and more universal at present, the current technological trend that merges mutually with mobile phone of GPS, the i.e. integrated GPS module in mobile phone of having occurred; Realize GPS functions such as traditional navigation; This GPS mobile phone is as shown in Figure 1 usually, include mobile phone nucleus module 1 ', be used to realize each item function that existing mobile phone can reach; GPS module 2 ', be used to realize the GPS function; Battery 3 ', be used for to mobile phone nucleus module 1 ' with GPS module 2 ' provide power supply, with guarantee mobile phone nucleus module 1 ', GPS module 2 ' ability operate as normal.A problem of bringing therefrom is exactly: the power saving problem of mobile phone.Because mobile phone is as a kind of consumption electronic product of carrying, its volume requirement higher (at present on the market mobile phone all be advantages of small volume basically) to equipment, these characteristics have just determined mobile phone can not be equipped with the battery that capacity is bigger.With present common 850mAH lithium battery is example, and the standby current of supposing conventional mobile phone is 5mA, and then its stand-by time is 850 ÷ 5=170 hours in theory, approximately can standby about 7 days; And if the GPS mobile phone then needs the current power dissipation about the 20mA of increasing more, promptly the standby current of mobile phone will reach 25mA, and its stand-by time is 850 ÷ (5+20)=34 hours, about about 1.5 days.This shows that after the integrated GPS module of conventional mobile phone, stand-by time greatly reduces.In order to guarantee the normal use of mobile phone, or use more jumbo battery instead, or frequent charge, this all can cause in the use extremely inconvenient of mobile phone.

Summary of the invention

The objective of the invention is to overcome the deficiency of prior art; The method of a kind of GPS mobile phone power saving is provided; Make the GPS mobile phone under holding state, can let the GPS module also get into power down mode; Make the stand-by power consumption of GPS mobile phone approach the stand-by power consumption of conventional mobile phone, thereby prolonged the stand-by time of GPS mobile phone.

The technical solution adopted for the present invention to solve the technical problems is: the method for a kind of GP8 mobile phone power saving; Be in the GPS mobile phone that includes mobile phone nucleus module, GPS module, battery, to increase by a vibration detection module, it comprises workflow and the workflow under the power down mode under the operating state:

Down, it comprises the steps: in working order

A. the cpu central processing unit of the mobile phone nucleus module time counter CT zero setting that it is built-in, promptly initialization time counter;

B. the cpu central processing unit of mobile phone nucleus module regularly detects the vibration detection module according to pre-set time interval;

C. the cpu central processing unit of mobile phone nucleus module judges whether the vibration detection module detects vibration, as detects vibration, then returns step a; Otherwise, continue next step;

D. the cpu central processing unit of mobile phone nucleus module adds up time counter, i.e. CT=CT+1;

E. whether the time value CT of the cpu central processing unit judgement time counter of mobile phone nucleus module greater than the time value of predefined entering power down mode, as not surpassing set point, then returns step b; Otherwise, continue next step;

F. the cpu central processing unit of mobile phone nucleus module control GPS module gets into power down mode;

Under power down mode, it comprises the steps:

G. the cpu central processing unit of the mobile phone nucleus module time counter CT zero setting that it is built-in, promptly initialization time counter;

H. the cpu central processing unit of mobile phone nucleus module regularly detects the vibration detection module according to pre-set time interval;

I. the cpu central processing unit of mobile phone nucleus module judges whether the vibration detection module detects vibration, as does not detect vibration, then returns step g; Otherwise, continue next step;

J. the cpu central processing unit of mobile phone nucleus module adds up time counter, i.e. CT=CT+1;

K. whether the time value CT of the cpu central processing unit judgement time counter of mobile phone nucleus module as not surpass set point, then returns step h greater than the predefined time value that withdraws from power down mode; Otherwise, continue next step;

L. the cpu central processing unit of mobile phone nucleus module control GPS module withdraws from power down mode, promptly gets into operating state.

The invention has the beneficial effects as follows; Owing to adopted and in the GPS mobile phone that includes mobile phone nucleus module, GPS module, battery, increased by a vibration detection module; Mechanical oscillation through vibration detection module detection of handset; When the vibration detection module does not detect vibration signal, mean that then the position of mobile phone does not change, mobile phone nucleus module may command GPS module gets into power down mode; Otherwise, when the vibration detection module detects vibration signal, meaning that then change possibly take place in the position of mobile phone, mobile phone nucleus module may command GPS module withdraws from power down mode; Make the GPS mobile phone under holding state, can let the GPS module also get into power down mode, make the stand-by power consumption of GPS mobile phone approach the stand-by power consumption of conventional mobile phone, thereby prolonged the stand-by time of GPS mobile phone.
