Embodiment

Disclosed all characteristics in this instructions, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.

Disclosed arbitrary characteristic in this instructions (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.

Below, with combining accompanying drawing that the present invention is done further detailed explanation.

As shown in Figure 1, be the theory diagram of the automatic early-warning system of quantificational electric quantity of the present invention.The hardware circuit of automatic early-warning of the present invention mainly comprises 5 functional modules (part): information acquisition module 1, initialization module 2, clock module 3, quantitative comparison module 4, output module 5.The major function of its each functional module is:

1, information acquisition module: the main information about power of being responsible for gathering in real time battery.If under the situation that charging is fully accomplished, the battery electric quantity that then will gather this moment deposits V in _FullIn, and completely be worth as the electric weight of reality; If in use, the charge value that then will gather in real time deposits V in _ActualPromptly accomplish fully charging: V _Full=Value; Use: V _Actual=Value.Wherein, above-mentioned Value is expressed as the charge value of real-time collection.

2, initialization module: this module is accomplished the setting of initial value, and calculates relevant quantitative values according to the initial value of setting, and is kept in each register.Comprising the setting to register Set and register Step, these two registers all receive the setting value of external interface input.

Setting through to the value of register Set and register Step calculates early warning power threshold V automatically _Step

3, quantitative comparison module: mainly accomplish real-time charge value V in the use _ActualWith early warning power threshold V _StepComparison.Work as V _Actual≤V _StepThe time, provide early warning signal Call, i.e. Call=Ture (or 1).

4, output module: early warning signal Call is outputed to the functional module of appointment, to trigger the early warning indicator signal.For example trigger warning music, warning light etc.

5, clock module: the sequential all the time that provides system to need, the assurance security of system is moved in an orderly manner.

Below, in conjunction with the theory diagram of Fig. 2 and system automatic early warning method of the present invention is done detailed explanation.The flow process of the method for its realization automatic early-warning is as shown in Figure 2, and a kind of automatic early warning method of quantificational electric quantity comprises:
