Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
See Fig. 1, a kind of storage battery, comprise battery container (not shown), and the GSM/GPS module 2 be arranged in battery container, powered for GSM/GPS module 2 by the battery feed 1 in battery container, GSM/GPS module 2 not only can be used for antitheft, also can be used for the use information gathering user, GSM/GPS module 2 and remote monitoring center communication.
In the utility model, between battery feed 1 and GSM/GPS module 2, be provided with electronic switch, see Fig. 2, by the opening and closing of electronic switch control GSM/GPS terminal 2 automatically.Electronic switch comprises two control sources, be respectively the first control input end VIN and the second control input end SW_ENABLE, wherein, the first control input end VIN connects the positive pole of battery feed 1, and the second control input end SW_ENABLE is then connected to the CPU of GSM/GPS module 2.Electronic switch also comprises an output VOUT, is connected to GSM/GPS module 2, and the output control GSM/GPS module 2 of output VOUT opens and closes.
First control input end VIN is connected respectively to the negative pole of the first voltage stabilizing didoe D1 (12V) and the positive pole of diode D2, the positive pole of the first voltage stabilizing didoe D1 is connected to the first end of the first resistance R1 for dividing potential drop, second end of the first resistance R1 is connected to the first end of the second resistance R2 for dividing potential drop, the second end ground connection of the second resistance R2, the negative pole of diode D2 is connected respectively to one end of the first electric capacity C1 and the source electrode of PMOS Q1, the other end ground connection of the first electric capacity C1, the negative pole of diode D2 is also connected respectively to the 3rd resistance R3, the first end of charge and discharge capacitance C2, and second negative pole of voltage stabilizing didoe D3, 3rd resistance R3, second end of charge and discharge capacitance C2, the positive pole of the second voltage stabilizing didoe D3, the grid of PMOS Q1 is all connected to the first end of the 4th resistance R4, the drain electrode of PMOS Q1 is then as above-mentioned output VOUT, above-mentioned diode D2 plays the effect of reverse connecting protection, prevent battery feed 1 reverse-connection damage circuit, and above-mentioned second voltage stabilizing didoe D3 is to the pressure limiting of PMOS Q1 grid, prevent the grid overvoltage of PMOS Q1.
Two control source controls PMOS Q1 conducting and cut-off respectively by a triode, and in the utility model preferred embodiment, two triodes are NPN triode.The two ends of the second resistance R2 are parallel with the second electric capacity C3, the first end of the second resistance R2 and the second electric capacity C3 is all connected to the base stage of a NPN pipe Q2, the collector electrode of the one NPN pipe Q2 is connected to second end of above-mentioned 4th resistance R4, second end of the second resistance R2 and the second electric capacity C3, the equal ground connection of emitter of a NPN pipe Q2, the resistance of the 3rd resistance R3 is greater than the resistance of the 4th resistance R4.
Second control input end SW_ENABLE is connected to the base stage of the 2nd NPN pipe Q3 by the 5th resistance R5, the 6th resistance R6 is connected with between the base stage of the one NPN pipe Q3 and emitter, the grounded emitter of the one NPN pipe Q3, and the collector electrode of a NPN pipe Q3 is connected to second end of above-mentioned 4th resistance R4, above-mentioned 5th resistance R5 is biasing resistor, prevent short circuit and produce larger base current, the 6th resistance R6 then plays jamming-proof effect.
Thus, the 3rd resistance R3 and charge and discharge capacitance C2 forms the gate discharge loop that PMOS Q1 closes, and RC time constant is large, and the delay time ended by the end of PMOS Q1 from NPN pipe Q2/ a 2nd NPN pipe Q3 is long.4th resistance R4 and the second electric capacity C3 forms the gate charges loop of PMOS Q1 conducting, RC time constant is little, the delay time being conducting to PMOS Q1 conducting from NPN pipe Q2/ a 2nd NPN pipe Q3 is short, and electronic switch can be made thus to realize opening speed very fast, closing velocity is slower.
When battery feed 1 connects commercial power charged, first control input end VIN voltage raises, until during about 13.5V, first control input end VIN is by the first voltage stabilizing didoe D1, first resistance R1/ second resistance R2 dividing potential drop, one NPN pipe Q2 conducting, charged to charge and discharge capacitance C2 by the 4th resistance R4, when the voltage of charge and discharge capacitance C2 is elevated to the conduction threshold being greater than PMOS Q1, PMOS Q1 conducting, output VOUT makes GSM/GPS module 2 obtain power supply to start working, now, second control input end SW_ENABLE is high level, make the 2nd NPN pipe Q3 conducting, the same with the principle of a NPN pipe Q2 conducting, make PMOS Q1 conducting always, reach the object of latch, now, even if the first control input end VIN voltage drop, PMOS Q1 is conducting always also.
When the first control input end VIN voltage drop is to below 13.5V, a NPN pipe Q2 ends, but due to the 2nd NPN pipe Q3 be GSM/GPS module 2 control, can latch, make PMOS Q1 continue conducting.
If the first control input end VIN voltage continues to decline, in order to prevent battery overdischarge, during as dropped to 10V (CPU of GSM/GPS module 2 monitors VOUT in real time), the CPU of GSM/GPS module 2 is to the second control input end SW_ENABLE output low level, 2nd NPN pipe Q3 ends thus, PMOS Q1 time delay cut-off (the gate discharge loop closed by PMOS Q1 realizes time delay).
Owing to having two control sources, as long as one of them is effective, PMOS Q1 is with regard to conducting, even if GSM/GPS module 2 is owing to restarting, SW_ENABLE signal is temporarily uncontrollable, and PMOS Q1 still maintains conducting state, and electronic switch just can export high level, when controlling source void in whole for two, then PMOS Q1 time delay about 5S closes.
In sum, when battery feed 1 charges, voltage rise is to a certain extent (during floating charge during about 13.8V, reach as high as 14.8V), GSM/GPS module 2 just can be opened automatically, realize (now preferably also needing by the CPU of gsm system transfer instruction to GSM/GPS module 2 without button Auto Power On, activate GSM/GPS module 2, then electronic switch conducting always after activation, if do not send instruction, then electronic switch time-delay closing, in order to avoid when equipment is not sold away, start battery consumption power supply 1 capacity, consume GSM campus network), after this, if storage battery is in charged state always, then electronic switch conducting always, when battery feed 1 leaves standstill the not used time, voltage compare low (about 13.4V), then GSM/GPS module 2 can not be triggered start, reaches the object of power saving, protects battery feed 1.
