Table 1
Wherein the 9th pin is the SIM test side, the 9th pin ground connection when not having SIM to insert; When SIM inserts because the 9th pin links to each other with+3.3V high level through resistance R 4, therefore at this moment the 9th pin by on draw and put+3.3V.The opening or closing of output voltage State Control second switch module through the 9th pin under the above-mentioned different conditions.Particularly, the grid of the 2nd NMOS pipe Q3 in the 9th pin of SIM seat and the second switch module links to each other, when SIM inserts; The 9th pin output high level, the conducting of the 2nd NMOS pipe Q3 high level, its drain-to-source conducting ground connection; So the grid voltage of the 2nd PMOS pipe Q4 is low; Because the PMOS pipe is the low level conducting, so this moment, the 2nd PMOS pipe Q4 also was in conducting state, thereby whole second switch module is in open mode under the state that SIM inserts;
Simultaneously, embedded controller EC (Embedded Controller) is the state through command detection SIM seat the 9th pin aspect software, when detecting the 9th pin and be output as high level; EC sends incoming control signal to the first switch module, and this incoming control signal is a high level, makes NMOS pipe Q1 conducting thereby the NMOS grid in first switch module receives this high level signal; Because its drain-to-source conducting ground connection is so the grid voltage of PMOS pipe Q2 is low, because the PMOS pipe is the low level conducting; So this moment, the one PMOS pipe Q2 also was in conducting state; Thereby whole first switch module is in open mode under the state that SIM inserts, and when no SIM inserts, SIM seat the 9th pin output low level; Make the 2nd NMOS pipe Q3 turn-off, and then whole second switch module is in closed condition;
The state of opening simultaneously in first switch module and second switch module; The first switch module input end signal is sent to the output terminal of second switch module; The reference voltage that is second switch module output+3.3V identical with 3G network interface card operational voltage value is delivered to 3G network interface card deck; Transmission through 3G network interface card deck makes the 3G network interface card be in open mode, please consults table 2 in the lump, and table 2 is a 3G network interface card unlocking condition table; This moment, portable computer was in the situation 1 in the table 2, and this equipment can the running wireless network operation.

Table 2
Further, above-mentioned EC can discharge the signal that SIM inserts to application object AP when detecting the 9th pin and be output as high level, the prompting that the output of application programming interfaces control man-machine interface has SIM to insert.Further, above-mentioned EC is when detecting the 9th pin and be output as high level, and EC can postpone certain hour and send incoming control signal to first switch module again; Time delay, the unit was a second level; Be 1-2 second preferred time delay, can prevent like this that the user from inserting in the process of SIM to insert because of the shake flase drop has measured card, guarantee user's complete stability ground insertion SIM after; And then supply power, effectively protect SIM.
Certainly; When EC is detecting the 9th pin and is being output as high level; Also do not accomplish before the time-delay process, when not sending incoming control signal to the first switch module of high level (situation 2 in the table 2), first switch module is in closed condition; The 3G deck can not obtain through first switch module and second switch module deliver to+the 3.3V WV, so 3G network interface card this moment (being radio access module) is in closed condition.But this process is very of short duration, because EC can automatic time delay when detecting the 9th pin and be output as high level sends the control signal of high level.
Because the voltage output pin of 3G network interface card links to each other with the power pin of SIM seat, be under the closing state at the 3G network interface card, SIM is not in running order after inserting, so played the effect that reduces power consumption to a certain extent.In addition; Know according to above-mentioned; The condition that 3G network interface card (being radio access module) is opened is that first switch module and second switch module are in open mode simultaneously; And one of condition that first switch module and second switch module are opened is to have SIM to insert, and is to power on behind the first plug-in card in the process of whole insertion SIM, therefore when hot plug-in card, has protected SIM can not burnt effectively.
When the user need extract SIM; EC detects the user and clicks the trigger pip that man-machine interface selects to close the 3G network interface card; Thereby EC sends to extract according to detected above-mentioned trigger pip and controls signal to first switch element; This extracts control signal is low level, thereby the NMOS grid in first switch module receives this low level signal the one NMOS pipe Q1 is turn-offed, 3G network interface card (being radio access module) quit work (i.e. situation in the table 2 3).Because the required WV of SIM work is from the 3G network interface card, so when 3G network interface card (being radio access module) when quitting work, SIM is in the no power state, the user can extract SIM safely at this moment.
Certainly, above-mentioned EC can discharge the signal that SIM extracts to application object AP when detecting trigger pip, the relevant prompting that application programming interfaces control man-machine interface output SIM is extracted.
Further; The portable computer that present embodiment provides also comprises a button; This button is desired to extract SIM or is closed the shortcut that the 3G function of surfing the Net is operated as the user, and whether said EC detects this button and move, when this button is pressed; EC sends to extract and controls signal to first switch module it is closed, thus the user-friendly SIM of extracting.
Obviously, for the situation in the table 24, when in the SIM seat during no SIM, SIM seat test side output low level, the second switch module is closed, thus the 3G deck can't obtain supply voltage, and this moment, no matter which kind of control signal EC sent, and the 3G network interface card all is in closed condition.
Whether to sum up, can know: work through 3G network interface card (being radio access module) and control SIM and whether can obtain WV, guaranteed to power on behind the first plug-in card in the plug-in card process, pulling out cuts off the power supply earlier in the card process afterwards pulls out card, thereby has protected the hot plug safety of SIM.Through the interlocking between two switch modules, implement the portable computer start provided in the present invention but do not have under the situation that SIM inserts the 3G network interface card and close fully, thereby reduce power consumption, prolongs standby time; In addition, under the situation that has card to insert, detect the trigger pip that the user sends through EC, the user only needs key swift to operate or just operates through man-machine interface can convenient and swift switch 3G network interface card, greatly facilitates user's use.
Fig. 4 is the circuit diagram of second switch module in another embodiment of the present invention; This second switch module also comprises a delay unit, and through the effect of delay unit, the voltage that first switch element is delivered to will be by the time-delay certain hour to the 3G network interface card; Thereby can prevent to insert because of the shake flase drop has measured card in the process of user's plug sim card; Guarantee the completely stable insertion SIM of user, and then power supply, SIM effectively protected.Said delay unit comprises resistance R 7 and capacitor C 6, and an end of resistance R 7 links to each other with the drain electrode of the 2nd NMOS, and its other end links to each other with the grid of the 2nd PMOS pipe Q4, and capacitor C 6 is connected across between the grid and ground of the 2nd PMOS pipe Q4.The delay time parameter of this delay circuit can be set through the capacitance of regulating resistance R 7 resistances and capacitor C 6.
Further; The second switch module also comprises filter unit and voltage regulation unit in one embodiment of the invention; Said filter unit and voltage regulation unit series connection; The output terminal of the 2nd PMOS pipe Q4 links to each other with the input end of filter unit, and the output terminal of this voltage regulation unit is connected to the feeder ear of 3G net (being radio access module).Voltage through the 2nd PMOS being managed the output terminal of Q4 carries out delivering to 3G network interface card deck again after filtering and the voltage stabilizing, can guarantee the job stability of 3G network interface card.Above-mentioned in the present embodiment filter unit and voltage regulation unit are built through basic components and parts such as some resistance, electric capacity.Filter unit and voltage regulation unit are technology as well known to those skilled in the art, repeat no more at this.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
