Embodiment
See also Fig. 1 and Fig. 2, Fig. 1 is the outside drawing of first embodiment of the invention device for logging on network 30, and Fig. 2 is the functional block diagram of Fig. 1 device for logging on network 30.Device for logging on network 30 includes a housing 31, a display panel 33 is located on the housing 31, be used for video data, a battery 32 is connected in housing 31, be used to provide device for logging on network 30 required electric power, storage unit 34 to be located in the housing 31, be used to store the data and a control module 38 of device for logging on network 30, be used to control device for logging on network 30.Display panel 33 can show user's interface (user interface) 36, operates device for logging on network 30 for the user.Storage unit 34 is a dynamic RAM module (DRAM module).In the present embodiment, the user can be by the 36 one data holding times 44 of input of user's interface, and on behalf of user's desire, this data holding time 44 preserve the time of storage unit 34 data.Thereafter, 38 of control modules can be preserved the time of its data of being stored to adjust device for logging on network 30 according to data holding times 44 control battery 32.
As shown in Figure 2, control module 38 includes a computing unit 40 and a battery cell monitoring unit 42.The computing unit 40 of present embodiment has two functions, first, computing unit 40 can be converted to the data holding time 44 a preservation electric weight ratio 46 and show to user's interface 36, this preserves 46 representatives of electric weight ratio and desires to make data to preserve the ratio that required battery electric quantity of data holding times 44 accounts for all batteries electric weight, as 15%, 20% etc.; In addition, computing unit 40 also can be converted to the data holding time 44 one and reserve electric weight adjustment order 48 with control battery 32.48 monitoring batteries 32 can be ordered according to reserving the power supply adjustment in battery cell monitoring unit 42, the electric weight of reserving when battery 32 is less than being enough to preserve 34 data duration data holding times 44 of storage unit during required electric weight, control module 38 can manifest a predetermined information in user's interface 36 by control device for logging on network 30, closes device for logging on network 30 with the prompting user.
See also Fig. 3, Fig. 3 is a dialogue block schematic diagram 52 of Fig. 2 user's interface 36.As shown in Figure 3, device for logging on network 30 can respond user's needs, manifests dialogue block schematic diagram 52, imports the data holding time 44 for the user.After the input data holding time 44, the preservation electric weight ratio 46 of 52 meeting corresponding these data holding times 44 of demonstration of dialogue block schematic diagram is confirmed for the user.In addition, dialogue square 52 also can show as relevant informations such as existing electric weight ratios 50 for user's reference.
See also Fig. 4, Fig. 4 is the electric energy control process flow diagram of Fig. 1 device for logging on network 30.The electric energy control flow process of device for logging on network 30 is as follows:
Step 100: from the 36 reading of data holding times 44 of user's interface.
Step 102: the data holding time 44 is converted to preservation electric weight ratio 46.(preserving electric weight ratio=data holding time * P)
Step 104: will preserve electric weight ratio 46 and show to the 36 confession users affirmations of user's interface.
Step 106: data holding time 44 or preservation electric weight ratio 46 are converted to reservation electric weight adjustment order 48 to battery cell monitoring unit 42.
Step 106: order 48 monitoring batteries 32 according to reserving the electric weight adjustment; When control module 38 detects electric weight that battery 32 reserves less than being enough to preserve 34 data duration data holding times 44 of storage unit during required electric weight, control module 38 can manifest a predetermined information to remind the user by control device for logging on network 30.
Generally speaking, because storage unit 34 is made of dynamic RAM (DRAM), the time of its data storage is directly proportional with required electric weight, so also have certain proportionate relationship between data holding time 44 and preservation electric weight ratio, typical computing formula is: preserve electric weight ratio=data holding time * P, wherein P is a conversion coefficient, can be along with device for logging on network circuit or battery performance and different, but can learn via experiment or enquiry circuit and battery specification.
In addition, electric energy control flow process of the present invention is not limited to upper type.The step (step 102,104) of for example calculating and show the electric weight ratio can not carried out or the pending data holding times 44 are set and carry out after finishing (step 106) again; For example control module 38 is not limited to remind the user to manifest predetermined information again, and otherwise (as sending prompt tone) reaches identical purpose.In fact, reserve electric weight so long as control battery 32 via the mode of input or video data holding time 44, all should spirit according to the invention.
See also Fig. 5 and Fig. 6, Fig. 5 is the dialogue block schematic diagram 60 of another embodiment of the present invention, and Fig. 6 is the electric energy control process flow diagram of Fig. 5 embodiment.Different with previous embodiment is, dialogue block schematic diagram 60 is to import for the user earlier to preserve electric weight ratio 62, show the corresponding data holding time 64 again, after person to be used confirmed, control circuit 38 promptly can come monitoring battery 32 with the data holding time 64 according to preserving electric weight ratio 62.
As shown in Figure 6, the electric energy control flow process of present embodiment is as follows:
Step 200: from user's interface 36 reading and saving electric weight ratios 62.
Step 202: will preserve electric weight ratio 62 and be converted to the data holding time 64.(data holding time=preservation electric weight ratio * (1/P))
Step 204: the data holding time 64 is shown to the 36 confession users affirmations of user's interface.
Step 206: will preserve electric weight ratio 62 or data holding time 64 is converted to and reserves the electric weight adjustment and order to battery cell monitoring unit 42.
Step 208: reserve electric weight adjustment order monitoring battery 32 according to this; When control module 38 detects electric weight that battery 32 reserves less than being enough to preserve 34 data duration data holding times 44 of storage unit during required electric weight, control module 38 can manifest a predetermined information to remind the user by control device for logging on network 30.
According to above-mentioned step, the user can preserve the mode of electric weight ratio 62 equally by input, reaches the purpose of adjusting the data holding time 64.
Compared to known portable device for logging on network, the user interface is more affine in order to allow, function is more powerful for device for logging on network of the present invention, attempts providing the function of demonstration and setting data holding time, lowers the risk that data are not expected loss.Required time when the user can estimate to charge to next time voluntarily, and adjust data holding time of being desired with needs according to himself by electric energy control structure of the present invention, very convenient in the use.
The above only is preferred embodiment of the present invention, and all equivalences of doing according to claim of the present invention change and improve, and all should belong to the covering scope of patent of the present invention.
