Embodiment
For allowing auditor can more understand technology contents of the present invention, be described as follows especially exemplified by going out preferred embodiment.
Please refer to Fig. 1, Fig. 1 is the schematic diagram of portable electron device 1 of the present invention.In one embodiment of this invention, the portability device that portable electron device 1 can be an intelligent mobile phone, an individual digital helps (PDA) or other use battery modules, but be not limited with the present embodiment.
As shown in Figure 1, portable electron device 1 of the present invention comprises connecting interface 10, handover module 20 and detection module 30.Connecting interface 10 is arranged in a battery accommodating groove (not shown) of portable electron device 1, battery accommodating groove can an accommodating battery module 80, make when battery module 80 is installed in battery accommodating groove, the interface of battery module 80 and connecting interface 10 electrically connection status.No matter due to the battery module 80 being I2C interface or HDQ interface, at its interface, 4 contacts are all set, be respectively 1 power supply contact, 2 signal contacts and 1 ground contact, therefore the connecting interface 10 of portable electron device 1 of the present invention also correspondence 4 contacts are set, be electrically connected for corresponding with each contact of battery module 80, but the present invention is not as limit.
Handover module 20 is electrically connected at 2 contacts of connecting interface 10 by two circuits 21,22, these 2 contacts are connected to 2 signal contacts of corresponding battery module 80, to be received from the battery signal that battery module 80 is imported into by connecting interface 10 and two circuits 21,22, wherein battery signal comprises clock signal and data-signal.Handover module 20 has 2 groups of change-over switches 23,24, respectively set by corresponding aforementioned two circuits 21,22, different with the interface type in response to differentiated battery module 80, and switches corresponding transmission line.
Detection module 30 is electrically connected at aforementioned two circuits 21,22 respectively, to detect for each circuit 21,22.The clock signal imported into by detection aforementioned battery module 80 and data-signal, whether all with the arbitrary same line (namely clock signal and data-signal all transmit with circuit 21 or circuit 22) in two circuits 21,22 or respectively with different circuit transmission (namely clock signal and data-signal transmit with circuit 21 and circuit 22 respectively), differentiate the interface type corresponding to battery module 80.
Because the interface type according to battery module 80 is different, the battery signal imported into by two circuits 21,22 also can difference to some extent, therefore by the state detected by two circuits 21,22, can reach the effect of the interface type differentiating battery module 80.With regard to the battery module 80 of I2C interface, its clock signal and data-signal transmitted respectively by different 2 contacts, two circuits 21,22 making portable electron device 1 end corresponding can distinguish transmission clock signal and data-signal, and now detection module 30 can differentiate it is the battery module 80 installing I2C interface at present.And with regard to the battery module 80 of HDQ interface, its clock signal and data-signal merge only with the transmission of single signal contact, another signal contact is then responsible for the temperature variation detecting and transmit battery module 80 inside, circuit 21 or 22 transmission clock signal and a data-signal during portable electron device 1 end only can be connected by correspondence, another circuit then only transmits aforesaid temperature variation signal, and now detection module 30 can differentiate it is the battery module 80 installing HDQ interface at present.And detection module 30 is after differentiating the interface type determining the battery module 80 be electrically connected at present, can notify that handover module 20 switches corresponding transmission line with the interface type according to battery module 80.
Be the signal difference table that portable electron device of the present invention 1 is electrically connected with the battery module 80 of different interface type please also refer to Fig. 2, Fig. 2.In one embodiment of this invention, detection module 30 by detecting the signal level of each circuit 21,22, to assist to differentiate that clock signal and data-signal are all with the same line in two circuits 21,22 or respectively by different circuit transmission.Due to different signal levels can be produced according to phase xor signal when transmitting unlike signal, therefore the signal level detecting each circuit 21,22 by detection module 30 is in noble potential or electronegative potential, to judge the signal delivery status of each circuit 21,22, and then learn the interface type of the battery module 80 be electrically connected at present.
As shown in Figure 2, when portable electron device 1 of the present invention is electrically connected with the battery module 80 of I2C interface, because each circuit 21,22 is respectively in order to transmission clock signal SCL and data-signal SDA, now circuit 21,22 all can present the state of noble potential H; And when portable electron device 1 of the present invention is electrically connected with the battery module 80 of HDQ interface, due to the clock signal and the data-signal HDQ that only need two circuits 21 or 22 one of them (being assumed to be circuit 21) to transmit merging, this circuit 21 can present the state of noble potential H, and another circuit (being assumed to be circuit 22) is because of only in order to transmit temperature variation signal TH, its signal level can't be too high and make circuit 22 present the state of electronegative potential L.
Accordingly, suppose that handover module 20 presets the transmission circuit switching to the battery module 80 of corresponding HDQ interface, therefore when detection module 30 detects that two circuits 21,22 are all in electronegative potential or respective signal level difference (i.e. a noble potential and an electronegative potential), then judge now use the battery module 80 of HDQ interface or do not install battery module 80, handover module 20 keeps former corresponding circuits state; Once detect that at detection module 30 two circuits 21,22 are all in noble potential, then judge the battery module 80 now using I2C interface, therefore handover module 20 can switch to the transmission circuit of the battery module 80 of corresponding I2C interface according to the notice of detection module 30.Design by this, by the difference of signal level, the blocked operation of the corresponding transmission circuit of handover module 20 can be completed easily.
In one embodiment of this invention, detection module 30 also comprises timer 31, in order to prevent being connected improper between battery module 80 with connecting interface 10 or producing the phenomenon of jitter and cause erroneous judgement, calculate the whether lasting detection signal level of detection module 30 by timer 31 and reach a special time, if so, then using signal level measured at present as discrimination standard.
Portable electron device 1 of the present invention also comprises processing module 40 and display module 50.Processing module 40 is in order to receive the battery signal transmitted by handover module 20, to confirm the interface type of currently used battery module 80, and after receiving battery signal, just meeting is according to system boot program in the operational order actuating unit of user, to avoid producing the state such as system mistake or battery module 80 powerup issue.And processing module 40 is after system boot, read-write operation can be carried out for the state of battery module 80, and the status information of corresponding current battery module 80 can be shown by this display module 50, the interface type display etc. of such as electricity display, battery module 80.
Please refer to Fig. 3, Fig. 3 is the process flow diagram applying battery module method for sensing of the present invention.Should be noted, though battery module method for sensing of the present invention is described for the portable electron device 1 shown in Fig. 1 below, but the present invention is not limited to be applicable to portable electron device 1, any other portable electron device with similar framework is also applicable.As shown in Figure 3, battery module method for sensing of the present invention comprises step S301 to step S307.Each step of battery module method for sensing of the present invention will be described in detail below.
