Embodiment
The invention provides a kind of mobile terminal that prevents and do not stop method, system and the mobile terminal of restarting, for making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is the flow chart of the method preferred embodiment preventing mobile terminal from not stopping to restart provided by the invention, comprises the following steps:
Step S100, when mobile terminal has detected that charger inserts, whether mobile terminal has detected battery in real time and has been pulled out;
Step S200, when detecting that battery is pulled out, mobile terminal control starting procedure enter time delay wait for; When detecting that battery is not pulled out, mobile terminal keeps original state;
Step S300, after battery is pulled out, mobile terminal continue detect whether have battery to insert; When again having detected that battery inserts, mobile terminal has continued starting procedure.
Below in conjunction with specific embodiment, above-mentioned steps is described in detail.
After software detection is inserted to charger, when namely mobile terminal is in charged state, mobile terminal detects battery temperature in real time and detects the magnitude of voltage of pin, and more described battery temperature detects the size of the output voltage values of power management module in the magnitude of voltage of pin and mobile terminal.
Particularly, mobile terminal detects by analog digital converting unit ADC the magnitude of voltage Vadc that battery temperature detects pin, and namely the output voltage VDD of the power management module of mobile terminal is by the magnitude of voltage after pull-up resistor R1.If the battery in mobile terminal is not pulled out, then the output voltage VDD of power management module connects the thermistor R2 in battery by pull-up resistor R1, pull-up resistor R1 and thermistor R2 carries out dividing potential drop to output voltage VDD, then delivers to analog digital converting unit ADC and detects.The battery temperature that so analog digital converting unit ADC detects detects the magnitude of voltage Vadc=VDD*R2/(R1+R2 of pin).Owing to not being pulled out at battery, in charging process, thermistor R2 is along with the change resistance also respective change of temperature, but the resistance of thermistor R2 and pull-up resistor R1 does not have the difference of the order of magnitude, and namely both resistance gaps are within 10 times.From formula above, when battery is not in the terminal pulled out: 1/11VDD<Vadc<10/11VDD.Correspondingly, if the battery in mobile terminal is pulled out, because battery does not exist, so corresponding battery connector pin resistance to earth (being equivalent to R2) is very large, its value is far longer than pull-up resistor R1, and namely Vadc is more than or equal to 10/11VDD, Vadc and vdd voltage almost equal, but due to the existence of pull-up resistor R1, both values are also not exclusively equal.When battery is pulled out, both differences are quite little.
So when detecting that the magnitude of voltage of battery temperature detection pin is more than or equal to 10/11 of the output voltage values of power management module, then judge that battery is pulled out, the starting procedure of mobile terminal enters time delay and waits for, suspends configuration peripheral hardware.Specifically, if battery is pulled out, then mobile terminal is in off-mode, powered battery line level is almost nil, but mobile terminal is in charger insert state, charger can by power management module to the electric capacity of voltage regulation charging on powered battery line, the voltage on powered battery line is made to increase along with the energy increase of electric capacity of voltage regulation, when the voltage of powered battery line reaches the minimum incoming level needed for power management module, power management module activates correlation output level, start to the system power supply of mobile terminal (mainly powering to base band and internal memory), after output voltage stabilization, then power management module resets baseband chip, thus make base band start starting procedure, running operating system, after input/output interface state between the base band that configuration is relevant and peripheral hardware, software suspends configuration peripheral hardware, for example suspend collocating LCD, camera, the peripheral hardwares such as backlight and radio-frequency communication module, thus put and stopped mobile terminal and do not stop to restart, solve the battery when mobile terminal inserts charger charging to be pulled out and to cause mobile terminal not stop the problem of restarting.
Correspondingly, when detecting that the magnitude of voltage of battery temperature detection pin is greater than 1/11 of the output voltage values of power management module and is less than 10/11 of the output voltage values of power management module, then judge that battery is not pulled out, mobile terminal keeps original state.Specifically, under mobile terminal is in charged state, mobile terminal detects that battery temperature detects the voltage Vadc:1/11VDD<Vadc<10/11VDD of pin in real time, then battery is not pulled out, so mobile terminal still keeps original state, do not change, also there will not be mobile terminal not stop the phenomenon of restarting.Called mobile terminal keep original state just to refer to software does not make any change to mobile terminal because battery is not extracted in the terminal, original state is off-mode, remains off-mode now; Original state is open state, remains open state now.
After battery is pulled out, whether mobile terminal continues to detect has battery to insert; When again having detected that battery inserts, mobile terminal has continued starting procedure.Specifically, after battery is extracted, mobile terminal continues to detect the magnitude of voltage that battery temperature detects pin, when the magnitude of voltage that battery temperature detects pin is greater than 1/11 of the output voltage values of power management module and is less than 10/11 of the output voltage values of power management module, then judge that mobile terminal continues have battery to insert, mobile terminal continues starting procedure, continues configuration peripheral hardware, mobile terminal-opening.
After mobile terminal detects that battery is pulled out, namely detect that the magnitude of voltage of battery temperature detection pin is more than or equal to 10/11 of the output voltage values of power management module, the starting procedure of mobile terminal enters time delay and waits for, suspends configuration peripheral hardware.Mobile terminal continues to detect the magnitude of voltage Vadc that battery temperature detects pin, when battery temperature detect pin magnitude of voltage Vadc meet 1/11VDD<Vadc<10/11VDD time, then show have battery to insert in mobile terminal, so mobile terminal continues starting procedure, continue configuration peripheral hardware, thus complete configuration peripheral hardware, thus the phenomenon that mobile terminal do not stop to restart can not be produced.
Further, before described step S100, also comprise: whether S101, mobile terminal detect has charger to insert; When having detected that charger inserts, enter step S100.Namely detect mobile terminal and whether have charging, if not charging, software does not start or keeps waiting for, not triggering following flow process; When there being charging, software triggers, and enters follow-up flow process.

Particularly, described voltage comparison module 20 detects the size of the output voltage values of power management module in the magnitude of voltage of pin and mobile terminal for more described battery temperature; When battery temperature detects the voltage Vadc:1/11VDD<Vadc<10/11VDD of pin, battery is not pulled out, and start control module 30 controls mobile terminal and keeps original state.When the voltage Vadc that battery temperature detects pin is more than or equal to 10/11VDD, battery is pulled out, and start control module 30 controls the starting procedure of mobile terminal, enters time delay and waits for.
Further, described voltage detection module 10, after battery is pulled out, continues to detect the magnitude of voltage that battery temperature detects pin.When voltage comparison module 20 compare battery temperature detect the voltage Vadct of pin again between 1/11VDD to 10/11VDD time, show that battery is inserted in mobile terminal, start control module 30 controls the starting procedure of mobile terminal, exits time delay and waits for, continue starting procedure.
