Electric power system of the present invention, comprises power supply unit and current-collecting device, and power supply unit and current-collecting device are by second too network connectivity and being electrically connected to each other.Wherein, second too network there is the function of transfer of data and delivery of electrical energy.The outward appearance of electric power system of the present invention is roughly with shown in Fig. 1.But, the present invention further provides the current-collecting device that dynamic changes operator scheme.
According to conception of the present invention, the function of current-collecting device is improved.According to embodiments of the invention, current-collecting device has the function which kind of type sensing power supply unit belongs to.Further, current-collecting device also provides can be different according to the power of power supply unit, and switch with the function of different operation modes running.Such as: dynamical operator scheme can be supported, and the operator scheme of power saving simultaneously.Wherein, the consumed power of current-collecting device when high-effect pattern, higher than the consumed power when battery saving mode.
When current-collecting device senses and judges that power supply unit belongs to AT type, current-collecting device will be set to high-effect pattern.Related, current-collecting device is to meet the standard criterion running of AT type.
Suppose that current-collecting device is a wireless network base stations.Then, when wireless network base stations judges that power supply unit is AT type, wireless network base stations just uses higher wireless RF power output (or larger wireless power exports, wireless distances is comparatively far away, provide more complete function).
Otherwise when current-collecting device senses and judges that power supply unit belongs to AF type, current-collecting device will be set to battery saving mode.Related, current-collecting device changes the standard criterion running meeting AF type.
Same hypothesis current-collecting device is wireless network base stations.Then, when network base station judges that power supply unit is AF type, wireless network base stations just uses lower wireless RF power output (or lower wireless power exports, electric current consumption less).Such as, by wireless network base stations by 3 launch points originally provided, be reduced to and 1 launch point is only provided.
Refer to Fig. 3 A, it is the schematic diagram of the current-collecting device built-in function square of an embodiment of the present invention.Current-collecting device 43 is electrically connected on power supply unit (not painting formula) by grid line (not painting formula).Power supply unit provides power to current-collecting device 43 by grid line.Wherein, current-collecting device 43 can according to the power type of electric supply installation, and user is to the control of handover module in collocation, and selectivity operates on high-effect pattern or battery saving mode.The consumed power of current-collecting device when high-effect pattern, higher than the consumed power when battery saving mode.
The current-collecting device 43 of this embodiment comprises: handover module 432, control module 435.
Suppose that current-collecting device 43 is predetermined to be the high-effect pattern of running, but when the electric supply installation that reality is connected by grid line is AF type, user can adjust the setting of handover module 432 by operation behavior.
Then, handover module 432 according to this operation behavior, will produce switching signal Vsw to control module 435.Afterwards, the related function module (not painting formula) that control module 435 will control in current-collecting device 43, by the high-effect patten transformation preset to battery saving mode.
Hold, if current-collecting device is predetermined to be the high-effect pattern needing to use higher-wattage, when but power supply unit is but AF type, user is by modes such as hardware exchange operation behavior, software set operation behaviors, change the setting of handover module 432, and then current-collecting device 43 is converted to operate with battery saving mode.
Handover module 23 comprises: diverter switch and coupling element.Wherein diverter switch is in the first conducting state or the second conducting state according to operation behavior; According to the conducting state of diverter switch, selectivity is electrically connected on diverter switch to coupling element, and then selectivity produces couple current according to the status of electrically connecting with this diverter switch.Whether the conducting of coupling element, by the related voltage level affecting switching signal.
Such as, when diverter switch is in the second conducting state, coupling element produces couple current, and makes the voltage of switching signal be high level accordingly, and vice versa.Further details when operating about handover module 232, please hold rear explanation.
Refer to Fig. 3 B, it is the schematic diagram of the current-collecting device built-in function square of the another kind of embodiment of the present invention.The current-collecting device 23 of this embodiment comprises: sensing module 231, handover module 232, control module 235 and alarm module 233.
Wherein, sensing module 231 is by second too network connectivity and be electrically connected to power supply unit (not painting formula).In addition, sensing module 231 is electrically connected on handover module 232 and alarm module 233.Handover module 232 is also electrically connected on control module 235.
Current-collecting device 23 receives the network signal transmitted by power supply unit by sensing module 231.By sensing module 231, current-collecting device 23 will monitor the operating mode of power supply unit automatically.
According to conception of the present invention, whether sensing module 231 can comprise two event graded signals (two-event classification, referred to as 2EC) according to network signal, judges the type of power supply unit.
If network signal comprises two event graded signals, current-collecting device 23 will judge that power supply unit belongs to AT type accordingly.Otherwise if network signal does not comprise two event graded signals, judgement power supply unit is belonged to AF type by current-collecting device 23.
After sensing module 231 judges the type of power supply unit, point out user about the compatible situation between power supply unit, current-collecting device 23 by alarm module (233).Alarm module 233 can by modes such as cresset, the sound, Word messages, prompting.
For cresset: when belonging to the normal operation situation in Fig. 2 when power supply unit and current-collecting device 23, alarm module 233 can show green cresset; When power supply unit and current-collecting device 23 belong to the abnormal case of Fig. 2, then alarm module display red light cresset.Thus, user can know judgement according to red light cresset, and the power supply unit connected at present, is not enough to provide the electric energy needed for current-collecting device 23 normal operation.
In like manner, alarm module 233 also can pass through the mode such as Word message, the rapid sound, and prompting user current-collecting device 23 may produce the situation of abnormal operation.
Thereafter, user can pass through handover module 232, by modes such as software set operation behavior or hardware exchange operation behaviors, changes the switching signal Vsw that handover module 232 produces.After handover module 232 produces switching signal Vsw to control module 235, control module 235 controls the related function module (not painting formula) in current-collecting device 23 again, operates on corresponding operator scheme.
When control module 235 changes operator scheme, and then after making current-collecting device 23 no longer be in abnormality, alarm module 233 just stops producing information warning.
As previously mentioned, current-collecting device may be IP telephone machine, wireless network base stations, network video recorder etc.Therefore, along with the type of current-collecting device 23 is different, control module 235 also correspondingly can control relevant functional module, provides corresponding high-effect pattern, the operating function of battery saving mode.
Below, utilize Figure 4 and 5 that the purposes of handover module 232 is described.Wherein, Fig. 4 illustrates when power supply unit is AF type, and how handover module 232 produces switching signal to control module.Fig. 5 illustrates when power supply unit is AT type, and how handover module 232 produces switching signal to control module.
Certainly, the implementation of handover module 232 not graphicly to be limited with this.Moreover, about the level of the switching signal that handover module 232 produces, be the corresponding relation of AF type, AT type with power supply unit, be not also limited with definition mode herein.
Refer to Fig. 4, when its input signal is not containing two event graded signals, the schematic diagram of handover module 232 internal state.In this is graphic, handover module 232 comprises diverter switch 235a, coupling element 235b and multiple resistance R1, R2, R3, R4, R5, R6.
In this embodiment, the switching of diverter switch 235a may produce two kinds of conducting states, and the first conducting state is, first pin of diverter switch 235a is connected with the second pin, and the 4th pin and the 5th pin; The second conducting state is, second pin of diverter switch 235a is connected with the 3rd pin, and the 5th pin is connected with the 6th pin.
First pin of diverter switch 235a is electrically connected to 48V, the 3rd pin and is electrically connected on the 48V that network signal Vin provides by the second resistance R2 by the first resistance R1.Second pin of diverter switch 235a is electrically connected on input module (not painting formula), in order to input power supply signal Vpd.Wherein, the producing method of power supply signal Vpd does not need to be defined.Such as: power supply signal Vpd may be by input module, changes and draw network signal Vin.The setting position of input module does not need to be defined yet.
Such as, input module can be arranged in handover module, then, after network signal being converted to power supply signal Vpd, then the process of output switching signal Vsw all can be carried out in handover module according to power supply signal Vpd.This kind of way can be applicable to the embodiment of Fig. 3 A.
And for example, input module can be arranged in sensing module, and now, network signal, by sensing module, is first converted to power supply signal Vpd by current-collecting device.Thereafter, then by handover module 232 according to power supply signal Vpd output switching signal Vsw.This kind of way can be applicable to the embodiment of Fig. 3 B.For ease of illustrating, all suppose that handover module is the configuration scenario of Fig. 3 B below.
4th pin of diverter switch 235a is open circuit, the 5th pin is ground connection.6th pin of diverter switch 235a and coupling element 235b, the 3rd resistance R3 are electrically connected on first node S1 jointly.
Coupling element 235b can be optical coupling element (optical coupler).The left side of coupling element 235b is input, right side is output.Coupling element 235b has good isolation features, the voltage received in order to isolation left side, and the operating voltage of the chip internal on right side.Therefore, the left side of coupling element 235b works in the environment (such as: 48V) of relative high level, right side then works in relatively low level environment (such as: 3.3V).
The left side of coupling element 235b is electrically connected on the 3rd resistance R3 and earthed voltage (0 volt), the right side of coupling element 235b is electrically connected on the 4th resistance R4 and earthed voltage.
3rd resistance R3 is electrically connected between 48V and first node S1, the 4th resistance R4 is electrically connected between 3.3V and Section Point S2.5th resistance R5 is electrically connected between Section Point S2 and Controlling vertex Sctrl.6th resistance R6 is electrically connected between Controlling vertex Sctrl and earthed voltage.
When power supply signal Vpd is AF type, diverter switch 235a is in the first conducting state.
As seen from Figure 4, the 6th pin of diverter switch 235 is equivalent to sky and connects state (open circuit), the 48V voltage now above the 3rd resistance R3, and by the left side by the 3rd resistance R3 and coupling element 235b, conducting is to earthed voltage.Therefore, the left side of coupling element 235b, by because be connected with earthed voltage by light-emitting diode, produces the voltage of about 1.2V in first node S1.
When light-emitting diode on the left of coupling element 235b produces forward bias voltage drop, the light that diode sends, will be radiated in the base stage junction of optotransistor on the right side of coupling element 235b, and then produces collected current Ic.Now, the optotransistor on the right side of coupling element 235b can be considered conducting.
Due to the cause of the optotransistor conducting on the right side of coupling element 235b, the 3.3V voltage above the 4th resistance R4, will through the 4th resistance R4 generation current to earth terminal.Now, the switching signal Vsw between the 5th resistance R5 and the 6th resistance R6, thus will be in low level state.
In other words, when diverter switch 235a is in the first conducting state, coupling element 235b will produce couple current.By the generation of couple current, coupling element 235b and the 4th resistance R4 be connected in series, is in low level state by making the voltage of switching signal Vsw.
Refer to Fig. 5, when its input signal comprises two event graded signals, the schematic diagram of handover module 232 internal state.
When input signal is AT type, the 3rd pin of diverter switch 235a and the conducting each other of the second pin, and, the 6th pin and the 5th pin conducting each other.
As seen from Figure 5, the 6th pin of diverter switch 235a will by the 5th pin ground connection, now the voltage of 48V will by the 3rd resistance R3, the 6th pin, the 5th pin conducting to earthed voltage.Therefore, now the voltage of first node S1 is equivalent to earthed voltage (0V).
Now, the light-emitting diode on the left of coupling element 235b can't conducting.Therefore, the optotransistor on the right side of coupling element 235b is also open circuit.
Due to the cause of the optotransistor open circuit on the right side of coupling element 235b, 3.3V through the 4th resistance R4, the 5th resistance R5, the 6th resistance R6 and generation current to earth terminal.Now, the switching signal Vsw between the 5th resistance R5 and the 6th resistance R6, thus will be in high level state.
In other words, when diverter switch 235a is in the first conducting state, between coupling element 235b and earthed voltage, couple current can't be produced.Now, the voltage of switching signal Vsw, can determine according to the dividing potential drop of the 4th resistance R4, the 5th resistance R5 that are serially connected with between 3.3V and earthed voltage, the 6th resistance R6.Related, the voltage of switching signal Vsw will be high level state.
Explanation according to Figure 4 and 5 can be learnt, diverter switch 235a can according to the type of power supply unit, and generation high level or low level are in first node S1.Further, correspondence is also changed the level of switching signal Vsw by the right side of coupling element 235b.
Wherein, coupling element 235b can be regarded as: the high level in left side or low level state, conveys to the switching signal Vsw on right side.When supposing that control module 235 is a CPU, then Controlling vertex Sctrl can be electrically connected on the universal defeated in/out pin (General Purpose I/O, referred to as GPIO) of CPU.When CPU judge this universal defeated in/out pin be input as low level time, its operating mode that automatically switches is to battery saving mode; And, when CPU judge this universal defeated in/out pin be input as high level time, its operating mode that automatically switches is high-effect pattern.
In other words, after control module 235 receives switching signal Vsw, can be just high-voltage level or low voltage level according to switching signal Vsw, judge that the maximum power that power supply unit provides is 12.95W or 25.5W.Further, control module 235 can according to the supplied character of power supply unit, and the product load characteristic of adjustment current-collecting device 23 is to optimization.
Power supply unit is after by second, too network connectivity sends network signal to sensing module 231, and sensing module 231 will judge whether network signal comprises two event graded signals.In addition, sensing module 231 also correspondingly can produce power supply signal Vpd to handover module 232.Then, then by handover module 232 output switching signal Vsw to control module 235.According to the level of switching signal Vsw, control module 235 is by the operator scheme of adjustment current-collecting device 23.
When switching signal Vsw is low level, control module 235 controls current-collecting device 23 and operates in the lower pattern of power consumption, such as: AF pattern.Now, current-collecting device 23 judges that the maximum power that power supply unit is provided to current-collecting device is 12.95W.Therefore, automatic regulating power consumption is lower RF power output.
When switching signal Vsw is high level, control module 235 controls current-collecting device 23 and operates in the higher pattern (high-effect pattern) of power consumption, such as: AT pattern.Now, current-collecting device 23 judges that the maximum power that power supply unit is provided to current-collecting device 23 is 25.5W.Therefore, adjustment becomes power consumption is automatically higher RF power output.
Control module 235, according to the level of switching signal Vsw, judges the way of operator scheme that should enable, and can change according to application and define different.Such as: switching signal Vsw makes into represent AF pattern with high level, represent AT pattern with low level, or switching signal Vsw represents AF pattern and AT pattern etc. respectively with the change of specific low and high level.
Subsidiary one carries, and handover module 232 may be a physical switches as shown in Figures 4 and 5, or handover module 232 also may be existed by the mode of software set.About the implementation of handover module 232, belong to the application category of this case, it will not go into details herein.
Refer to Fig. 6, its current-collecting device judges the flow chart of the type of power supply unit according to network signal.First current-collecting device utilizes sensing module to receive network signal (step S11); Sensing module judges whether network signal comprises two event graded signals (step S13).
If so, current-collecting device judges that power supply unit is AT type (step S15) according to this.When power supply unit belongs to AT type, no matter current-collecting device is AT type or AF type, all can normal operation.Now, current-collecting device does not need the switching carrying out operator scheme.
If not, current-collecting device judges that power supply unit is AF type (step S17) according to this; Further, current-collecting device is by the operator scheme (step S19) of selectively changing current-collecting device.
Further illustrating about step S19, can with further reference to Fig. 7.
Refer to Fig. 7, it is after judging that power supply unit is AF type, the flow chart of current-collecting device selectivity adjustment operator scheme.
First, whether the operator scheme judging current-collecting device itself is AT pattern (step S191).If not, current-collecting device maintains and uses AF pattern (step S195).
If so, current-collecting device needs the switching carrying out operator scheme, is AF pattern (step S193) by AT patten transformation.Then, current-collecting device changes with AF mode operating (step S195).
Hold, adopt the current-collecting device of the present invention's conception, there is the function of the power type of sensing power supply unit.Further, when the power that power supply unit provides is lower than power needed for current-collecting device, information warning is sent.Providing by information warning, user, again by operation behavior, changes the operator scheme of current-collecting device.
Current-collecting device of the present invention has the function of the power type of monitoring power supply unit automatically, and provides the software operation interface, hardware switching switch etc. of hommization, allows user manually change the operator scheme of current-collecting device.Therefore, when current-collecting device realizes according to the present invention's conception, the installation process of second too network power supply system can significantly be simplified.
In sum, although the present invention with preferred embodiment disclose as above, so itself and be not used to limit the present invention.The technical staff in the technical field of the invention, without departing from the spirit and scope of the present invention, when being used for a variety of modifications and variations.Therefore, protection scope of the present invention is when being as the criterion depending on the appended right person of defining that applies for a patent.
