Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
Below, mainly the present invention is specifically described with data card method of supplying power to and system based on the pcmcia interface of notebook computer.In addition, be understandable that method of supplying power to of the present invention and system also can be used for other data cards of except that notebook computer (for example mobile phone).Specifically, system and method of the present invention is for having the burst mode operating characteristic, use the power amplification system of TDMA (TIME DIVISION MULTIPLE ACESS) standard work to power or other non-burst mode operating characteristic, use WCDMA, the electric of standards such as CDMA.
For the ease of understanding technical scheme of the present invention, at first introduce according to adaptation power supply of the present invention system 100.
As shown in Figure 1, this system 100 comprises five parts generally: pcmcia interface 102, and power converting system 104, charging management system 106, power amplifier load 110 and data card baseband system 108 are formed.
Pcmcia interface 102 is connectors of notebook computer and data card, and it to the data card power supply, also is notebook computer and data communication interface on the one hand on the other hand.
An analog channel is arranged between data card baseband system 108 and the charging management system, analog channel receives the monitoring value from 106 pairs of power amplifier operating voltage of charging management system, analog quantity is converted to digital quantity, and this value and normal value compared, if this value departs from range of normal value, then issue and turn-off instruction to charging management system 106, charging management system 106 and power amplifier load are disconnected, thereby the protective action of playing, it also assigns the adjustment parameter instruction simultaneously, make charging management system 106 readjust inner electric current and/or voltage parameter automatically, up to the requirement of satisfying the power amplifier load.
Fig. 2 is the process flow diagram according to data card self-adapting power supply method of the present invention, introduces below in conjunction with Fig. 2 and utilizes charging management system 106 to realize the data card method of supplying power to.
This method mainly may further comprise the steps: 202, and utilize the power converting system of data card that input voltage is carried out conversion, make the requirement of the power amplifier load of voltage conforms data card; 204, the threshold voltage of the charging management system of adjusting data card, the voltage that power converting system is exported satisfies the constant current condition of work of charging management system; 206, the mode of operation of judgment data card is according to the adjusting of judged result control to the threshold current of charging management system; 208, the power amplifier loaded work piece voltage of monitor data card, according to the operating voltage range of power amplifier load, charging management system determines whether self-adaptation adjustment power supply parameter.
Fig. 3 is the workflow diagram of the data card self-adapting power supply method based on charge management circuit according to an embodiment of the invention.
Wherein,, data card is inserted the socket of notebook pcmcia interface 102, power up to data card in step 302.
Secondly,, regulate the running parameter of power converting system 104, the output voltage from pcmcia interface 102 is changed, make its output voltage satisfy the operating voltage requirement of data card power amplifier load 110 in step 304 and 306.This step is mainly regulated the DC converter of power converting system 104.This step also is the basis of accumulator system energy storage under the TDMA working form.
To 312, regulate the threshold voltage of charging management system 106 in step 308, make the voltage of power converting system 104 outputs satisfy the constant-current charge condition.To regulate the constant-current charge voltage threshold repeatedly, make threshold value can meet the operating voltage range of power amplifier load above-mentioned, and the minimum operating voltage when satisfying the power amplifier loaded work piece, when guaranteeing that operating voltage is fallen, charging management system 106 still can be operated in constant current charging mode.Self just is provided with function the software of charging management system 106, in order to realize this purpose, need go to be provided with repeatedly the voltage steps value by the mode of software, and charging management system 106 just can enter the constant current mode of operation like this.
, carry out mode of operation and judge the radio frequency operation system of data card discern its network schemer automatically, and which kind of mode of operation the notification data card adopts according to the network that searches to 328 in step 314.Being divided into working form with the TDMA standard among the present invention is the class with burst mode operating characteristic of representative and the class that non-TDMA standard does not have the burst mode operating characteristic.Because in the two class mode of operations, the effect of accumulator system performance is different.
At TDMA is in the system with burst mode operating characteristic of representative, need to confirm the size of constant-current charge electric current, and this step determines that charging current can carry out in conjunction with the energy storage characteristic of energy-storage travelling wave tube in the accumulator system.Because the power amplifier operating voltage has a scope, so Dui Ying electric current also is a scope.Equally in order to realize this purpose, need go to regulate repeatedly the threshold value by the mode of software, when drawing big electric current in case the power amplifier load is in the burst mode duty, because when electric current increases, current-limiting resistance becomes voltage with current conversion, the pressure reduction at resistance two ends can increase, charging management system 106 will be by regulating the control voltage of power tube, increase its conducting resistance, the restriction electric current further increases, the closed control circuit of internal system will be brought into play the closed-loop control effect, and electric current is limited in the predetermined range, reach the purpose of current limliting.In order to improve the power supplying efficiency of pcmcia interface 102, need to reduce the power consumption on power tube and the current-limiting resistance, therefore the conducting resistance of the power tube of requirement selection is as much as possible little, and current-limiting resistance is as much as possible little.Because the power supply of the main circuit power supply of power tube is limited in the scope, the energy that provides of major loop may not satisfy the requirement of load like this, and that part of energy that lacks is just supplied by accumulator system above-mentioned.
Because it is multiple that the energy-storage travelling wave tube in the accumulator system has, its energy storage characteristic is also fully different, below with electric capacity as energy-storage travelling wave tube be example in conjunction with the estimation equation that Fig. 4 provides storage capacitor, just can select electric capacity according to this theoretical value.Because power amplifier loaded work piece voltage has a scope, regulation voltage can satisfy the job requirement of power amplifier in this scope, can select only electric capacity again.Because load current is relevant with voltage,, need in the operating voltage range of power amplifier load, adjust magnitude of voltage repeatedly therefore in order to find this two optimal parameters.Satisfy the energy storage requirement up to finding out appearance value size, cost is the suitable electric capacity of acceptable again.
As the 400 length T on that represent the power amplifier working time among Fig. 4,401 represent frame length.If pcmcia interface voltage is Vin, input current is I, and the conversion efficiency of supply convertor is η, and the supply convertor output voltage is Vout, output current is Iout, the power of power amplifier is W, and efficient is ξ, and the required peak point current of power amplifier is Ipeak, the capacity of storage capacitor is C, the charge stored amount is Q, and equivalent series resistance is Rc, does following estimation:
The supply convertor output current:
The peak point current that power amplifier is required:
Need the least charge of storing on the electric capacity: Q=(Ipeak-Iout) * Ton
Because in the capacitor discharge process, output voltage slowly descends, the electric charge that electric capacity stores is also reducing, and for the ease of estimation, needs the value of falling of calculating voltage, ideally drops into input voltage value estimation according to output voltage.
The capacity of storage capacitor:
Resistance in series to the electric capacity charging:
Top formula provides theoretical foundation for the selection of storage capacitor, owing to be that some comparatively ideal factors are considered in estimation, owing to causing walking line resistance, the influence that is subjected to PCB (PRINT CIRCUITBOARD) layout cabling changes in actual the use, Rc is the smaller the better, consider long-term easy inefficacy of working down at full capacity of electric capacity simultaneously, voltage has and falls in the capacitor discharge process on the other hand, consider because the difference of system works environment causes bearing power to change to some extent, take into account filtering, etc. factor, the electric capacity of actual selection should be bigger than the electric capacity that above-mentioned theory calculates, and stays enough surpluses in particular for loaded work piece under the rugged surroundings.
Shown in the step 318,326 and 328 of Fig. 3, under non-TDMA working form, in the promptly non-burst mode,, only need to regulate separately the threshold value and get final product, till satisfying the power amplifier load request if load current does not satisfy load request.In order to reach this purpose, the step value of a needs adjusting electric current is reset threshold and is got final product.Under the non-TDMA working form, accumulator system contrasts TDMA working form and non-TDMA working form not to the load makeup energy, and the duty of two-part accumulator system is different fully, the process that the former has Duoed an energy storage and released energy than the latter.
When the power amplifier load was in normal operating conditions, the operating voltage of power amplifier is instantaneous to be had and falls, and this falls relevant with working current.To shown in the step 340, under the TDMA standard, when being in burst mode work, if the electric current setting is excessive, then pcmcia interface 102 may not provide so big energy, causes the electric power system collapse as step 330.If it is too little that electric current is provided with, then the electric charge that stores in may be at a fixed time of the energy-storage travelling wave tube in the accumulator system is just fewer, the energy sum that energy that it provides and major loop above-mentioned provide just is not enough to satisfy the requirement of power amplifier load, certainly will influence the operate as normal of power amplifier load.Therefore to carefully adjust this current limliting thresholding, up to the job requirement of satisfying the power amplifier load.During normal condition, the energy that Charge Management major loop and accumulator system provide can satisfy the job requirement of the burst mode of power amplifier load.If the loaded work piece electric voltage dropping is unusual, can cause the brownout of pcmcia interface 102 output this moment, and whole data card will be crossed low and generation work is malfunctioning owing to operating voltage, or abnormal occurrence such as low pressure is locked.
In order to prevent the generation of this phenomenon; the voltage monitoring passage that charging management system carries is with the baseband system on this operational voltage value reported data card; monitor in real time; in case can be in closed condition by the mode power controlling pipe of software unusually; being connected of thorough disconnecting consumers and charging management system, thus play a protective role.For non-TDMA standard, though the power amplifier load can not drawn big electric current moment,, power amplifier loads in time of a whole frame all in running order, required electric current can be regarded steady state value as in a scope, need equally suitable working current, when working current be provided with excessive the time, same pcmcia interface 102 can not given enough power, can cause the electric power system collapse, when working current is provided with when too small, the power amplifier loaded work piece is unusual, and net will appear frequently falling in data card.
When charging management system 106 and power amplifier load 110 disconnections, this moment, exceptional value reported the baseband system 108 of data card, charging management system 106 in house softwares will be readjusted the current limliting threshold value automatically, till power amplifier load 110 normal and stable operation.Thereby finish the self-adaptation adjustment process of system.When data card was operated in the mobile environment, the fluctuation of network signal was different, and is strong sometimes, sometimes a little less than, the size of the emissive power when directly having influence on the work of data card power amplifier load 110, thereby the demand of remote effect electric current.When network signal dies down when causing power amplifier load emissive power to strengthen, original working current that is provided with will be not enough to satisfy the demand of power amplifier load 110, show that operating voltage falls increase this moment, cause load and charging management system to disconnect, charging management system 106 self-adaptations are adjusted the threshold value, it is increased, thereby satisfy the demand of load.When the network signal grow, same original working current that is provided with is greater than the demand of power amplifier load, and pcmcia interface 102 will provide output power to satisfy the requirement of load as required this moment.
What the present invention proposed realizes the method for supplying power to and the system of data card self-adapting having solved the desired current limliting problem of data card based on the pcmcia interface power supply based on charge management circuit.Carry out the method that current limliting compares with the special-purpose current limiter of existing employing and compare, it has saved the problem that the cost that brings of additional current limiter rises, and just can realize setting to electric current and voltage threshold by simple software control.Because its pcmcia interface power supply capacity of notebook of various brands has nothing in common with each other, cause the power amplifier load that the requirement of electric current and voltage parameter is had nothing in common with each other, thereby these can satisfy load at an easy rate by the software setting suitable parameters requirement makes same money data card stably to work in dissimilar notebook pcmcia interfaces.Thereby the present invention has the characteristics to the adaptation power supply of different notebooks.
On the other hand, when data card is in mobile duty, the intensity of network signal changes, therefore the power of power amplifier load can change, and by monitoring the variation of power amplifier loaded work piece voltage, dynamically adjust operating voltage and working current by software again, thereby being worked better, data card prevents the generation of net phenomenon, even fall net, also can recover networking automatically by adjusting operating voltage and electric current rapidly, when improving the data card job stability, realized the adaptation power supply under the varying environment.The present invention has fully excavated the hardware resource that data card carries, and the current-limiting apparatus that software resource need not additional dedicated can be realized the power supply based on pcmcia interface data card product, has saved the extra cost of system.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
