The invention provides a backup battery voltage measuring method, able to learn charging voltage of a backup battery without periodically providing it if need or user requires. And the method comprises the following stages of: for measuring the backup battery, as a user requires, reading the present charging voltage of the backup battery and providing it to the user; and sensing the present charging voltage and as it is below a certain voltage, providing it to the user.
Description
Technical field
The present invention relates to voltage measurement method, particularly do not need to provide periodically the charging voltage of reserve battery, when needs provide or user when claiming, can know the voltage measurement method of the reserve battery of this situation.
Background technology
Usually, the home computer is for user's exploitation, is used for purposes such as personal transaction device or Edutainment, the address term of the computer system of a kind of low price easy to use.The home computer comprises following several types: according to the size of computing machine, be placed on the desk-top computer of the enterprising enforcement usefulness of desk; No matter when and where the tourist is, as long as place it on the knee with regard to operable kneetop computer; It is put in the literature kit, can carries it and arbitrarily walk about, so that carry the notebook personal computer that forms for the purpose manufacturing; Be positioned on the palm, be easy to carry more and use, more the palm PC of miniaturization.
On the other hand, portable personal computer refers to the CE form narrowly as operating system, the individual computing computer of the hand size of employing.And when carrying, device that can input information is by using battery, move, utilize wireless telecommunications to personal digital assistant as the user, the terminating machine that can handle remote information.
Usually, portable personal computer need provide power supply by battery for being easy to carry property is provided.According to the characteristic of battery, initial battery has certain electric capacity.When the electric capacity of battery comprises electric current and during electric power, also can be called ampere-hour during electric current, the numerical value that its electric current that refers to battery output and the time that can use electric current multiply each other; Also can be called watt-hour during electric power, the numerical value that to be the electric power that can export of battery multiply each other with time that can electrification.Because electric power decides by electric current and voltage are multiplied each other, during electric current and conversion mutually during electric power, if determined to use the equipment of battery, the two central numerical value when only needing to measure electric current and during electric power just can be known another one numerical value.Electric capacity is in a certain equipment, and the battery of use can use decision standard how long.
Different according to time of using and environment for use, electric capacity is also different.Usually, use in the process of battery,, just belong to the low state of battery electric quantity that is difficult to make consumer if the electric capacity of battery is in below 5% of regular electric capacity at electric equipment.At this moment, should use the battery of other charging or the low battery of electric weight charged.According to the kind difference of electric equipment, the charging of use is also different with battery, and the standard that battery electric quantity is low also can change.As portable personal computer, require the low very strictness of standard of battery electric quantity of accurate electric equipment.Therefore, portable personal computer has main battery and reserve battery, if the voltage of main battery is reduced to the below horizontal of regulation, need to use reserve battery, receives the power supply of its supply from reserve battery, carries out the operation of suspension status such as data backup.
When not having main battery or under the emergency situations that some abnormal conditions takes place and the present status of the replacing of user's data protection, main battery and system is exerted an influence, the state of present equipment can be protected and keep to reserve battery.
Fig. 1 is the formation synoptic diagram of the voltage measuring apparatus of existing reserve battery.
System 10 is made of operating system 11 and device driver 12, by system interface, carries out communication with measurement display part 30, by hardware interface, is connected with reserve battery 20.
At first, according to operating system 11 in advance the cycles of regulation take turns detection, device driver 12 is called the detected value of reserve battery, the detected value of reserve battery 20 is called by device driver 12 and finishes.(S1)
Then, DC-DC converter 21 will be transformed to digital value from the present charging voltage value that reserve battery 21 reads, and send system 10 (S2) to, the present magnitude of voltage of storage reserve battery 20.
At this moment, the measurement display part of application area (gauging display) 30 is presented at data 31 values (S3) of the reserve battery of storing in the system realm.
Like this, system carries out the charging voltage value of reserve battery 20 is offered the action of measuring display part 30 by detecting the present charging voltage value of reserve battery 20 periodically in turn repeatedly.
Fig. 2 is the process flow diagram of the voltage measurement method of existing reserve battery.
With reference to Fig. 2, as follows to the process description of the voltage measurement method of existing reserve battery.Determine whether be system regulation cycle (interval) (S11), if the cycle of system's regulation, the present value (S12) of reserve battery is read in the device driver indication.Then,, read the present charging voltage value of reserve battery, and store system realm (S13) into by the DC-DC converter.
Then, application area is received in the present charging voltage value of the reserve battery of storing in the said system zone, shows (S14) on the measurement display part.
But, since the cycle that employing is stipulated in advance according to system, the detection method in turn of test constantly backup battery voltage, and there is the problem of bringing very big burden to the performance of system in the power supply of using system.
Summary of the invention
The present invention is in order to address the above problem, and its first purpose is for the user provides a kind of reserve battery that do not need to measure periodically, when needs time/user files a request, can detect the voltage measurement method of reserve battery of the charging voltage of reserve battery.
Second purpose of the present invention is for the user provides a kind of when accident takes place the user, measures reserve battery, and the voltage measurement method of reserve battery of the state of present reserve battery is provided.
The 3rd purpose of the present invention is to provide a kind of present charging voltage of responding to reserve battery for the user, when the present charging voltage of reserve battery of induction is in the time of can carrying out the voltage of minimum operation, can be to the voltage measurement method of the reserve battery of user notification.
To achieve these goals, the voltage measurement method of reserve battery of the present invention comprises following several stages:
For above-mentioned reserve battery is measured, when the user files a request, read the present charging voltage of above-mentioned reserve battery, and offer user's the 1st stage;
