Along with the development of wireless Internet access technology, wireless network card is more and more universal.We know, are that pcmcia interface by notebook computer provides to the wireless network card power supply with pcmcia interface.According to the physical electrical standard of PCMCIA, if pcmcia port output 3.3V, the quiescent current ability of its output is 500mA, and output average current ability is 750mA, and output peak current ability is 1000mA; If pcmcia port output 5V, the quiescent current ability of its output is 330mA, and output average current ability is 500mA, and output peak current ability is 660mA.Because the standard of PCMCIA limits, the power supply capacity of the pcmcia port of notebook computer is limited thereby as can be seen.Therefore, for the wireless network card of some high-power emissions, current limit circuit is arranged all on wireless network card usually, important is for fear of system because the excessive veneer that causes of supply current damages or system crash.
On the other hand, because each notebook manufacturer is to the understanding difference of PCMCIA agreement, cause the pcmcia interface power supply capacity of the notebook computer of various different brands in practice also inequality, for example the quiescent current of the PCMCIA of the notebook computer that some power supply capacity is strong can reach 750mA, and peak value surpasses 1A.And the pcmcia interface power supply capacity of some notebook computer conformance with standard just.
At present, the current limit circuit that wireless network card comprised with pcmcia interface be fixedly install or needs manually be provided with, even if be used in like this on the strong notebook computer of power supply capacity, also can't reach best communication effect.That is to say that such wireless network card can't be adjusted transmitting power according to the actual power ability of pcmcia interface on the notebook computer, to reach best communication effect.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method for self-adapting power consumption of wireless network card, realizes the actual power ability of wireless network card according to pcmcia interface on the terminal, and self adaptation reaches best communication effect.
For solving the problems of the technologies described above, it is as follows to the invention provides scheme:
A kind of method for self-adapting power consumption of wireless network card is used to provide terminal to carry out the wireless network card of wireless telecommunications, wherein, terminal has pcmcia interface, wireless network card has current-limiting circuit and pcmcia interface, and has set electric current warning value, voltage warning value in the wireless network card, comprises the steps:
Step 1: dynamic load is set in wireless network card;
Step 2: when terminal is carried out wireless telecommunications by wireless network card, adjust the dynamic load in the wireless network card, record the actual power ability of pcmcia interface on the terminal;

Then, begin to adjust the resistance value of (beginning to reduce) this dynamic load, and record the magnitude of voltage (step 102) on the pairing load current of dynamic load resistance value adjusted and this moment terminal pcmcia interface from maximum from initial value;
Judge that the described load current value that records is whether greater than the electric current warning value of wireless network card, or judge that magnitude of voltage on the described terminal pcmcia interface that records is whether less than the warning value of wireless network card, judge just whether the terminal power supply capacity reaches capacity, that is the actual power ability (step 103) of terminal; Here, when detecting pcmcia port actual power ability, it is also passable only to detect load current, and the voltage that only detects pcmcia interface is also passable, and the two also can in conjunction with judging;
If the described load current value that records is greater than the electric current warning value of wireless network card or the magnitude of voltage on the described terminal pcmcia interface that the records warning value less than wireless network card, then, this moment, the terminal power supply capacity reached capacity, and the magnitude of voltage on record described load current value that records this moment and the terminal pcmcia interface is the actual power ability of pcmcia interface on the terminal; Otherwise, continue to reduce the resistance value (step 104) of dynamic load, then, get back to step 102, up to the load current value that records greater than the warning value of the magnitude of voltage on the electric current warning value of wireless network card or the terminal pcmcia interface that records less than wireless network card;
Then,, adjusting the cut-off current of current-limiting circuit in the wireless network card according to the actual power ability of pcmcia interface on the measured terminal, such as, can realize by the reference voltage that software is adjusted current-limiting circuit; When wireless network card is used for the strong terminal of power supply capacity, the cut-off current of then suitable increase wireless network card current-limiting circuit, during terminal a little less than wireless network card is used for power supply capacity, the then suitable cut-off current (step 105) that reduces the wireless network card current-limiting circuit.Like this, just can realize the actual power ability of wireless network card according to pcmcia interface on the terminal, self adaptation reaches best communication effect.
In addition, can also be according to the actual power ability of pcmcia interface on the measured terminal, by adjusting the power amplifier transmitting power of wireless network card, such as, size to transmitting power limits, when wireless network card is used for the strong terminal of power supply capacity, and the transmitting power of then suitable increase wireless network card, otherwise, then reduce transmitting power.Like this, can realize the actual power ability of wireless network card according to pcmcia interface on the terminal equally, self adaptation reaches best communication effect.
The method of the invention, be applicable to the wireless network card of various pcmcia interfaces, GPRS (General Packet Radio Service for example, GPRS) wireless network card, WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) wireless network card, WLAN (Wireless Local AreaNetwork, WLAN (wireless local area network)) wireless network card etc., the wireless network card of various standards.
A kind of method for self-adapting power consumption of wireless network card of the present invention, be not restricted to listed utilization in specification and the execution mode, it can be applied to various suitable the present invention's field fully, for those skilled in the art, can easily realize additional advantage and make amendment, therefore under the situation of the spirit and scope of the universal that does not deviate from claim and equivalency range and limited, the examples shown that the present invention is not limited to specific details, representational equipment and illustrates here and describe.
