Embodiment
To a preferred embodiment of the present invention will be described in detail, should be appreciated that following illustrated preferred embodiment only is used for description and interpretation the present invention, is not limited to the present invention below in conjunction with accompanying drawing.
Fig. 1 has shown the scheme block diagram that the embodiment of the invention provides, and as shown in Figure 1, comprising:
Power analog switch has the Enable Pin of controlling the analog switch break-make, and the input signal of Enable Pin is provided by hardware watchdog, and promptly the output signal of hardware watchdog is as the input signal of power analog switch Enable Pin.During the mobile phone operate as normal, the output signal of hardware watchdog is a high level, and analog switch is in closure state, and cell voltage VBAT1 normally be the power supply of base band and radio frequency power amplification modules by power analog switch, and VBAT2=VBAT1 at this moment is between 2.8V～4.2V; When mobile phone crashed, the output signal of hardware watchdog was low level reset signal, and analog switch is in cut-off state, presents very high impedance, can be considered as open-circuit condition, and at this moment, VBAT2=0 is equivalent to the action of user's outage.
Hardware watchdog can be an asic chip, also can be CPLD, is responsible for clear dog by base band and radio frequency power amplification modules under the mobile phone normal operating conditions.
Wherein, when selecting asic chip to do hardware watchdog, specific requirement according to asic chip, mobile phone baseband and radio frequency power amplification modules are regularly by general input/output port (General Purpose Input Output, GPIO) export the clear dog signal that meets the demands, otherwise, surpass the reset signal that the unclear dog of preset time is then exported certain time length, when promptly asic chip is not received dog signal clearly in a period of time to the Enable Pin output reset signal of power analog switch.For example, carry out dog clearly by external chip input cyclic pulse signal in certain every 1.6s time of the asic chip requirement that resets, otherwise ASIC output 200ms low level reset signal, therefore, mobile phone baseband and radio frequency power amplification modules need regularly be exported corresponding cyclic pulse signal from the GPIO mouth according to the requirement of this ASIC, under mobile phone deadlock situation, mobile phone baseband and radio frequency power amplification modules can't be exported the clear dog of described cyclic pulse signal, therefore, ASIC output 200ms low level reset enable signal power analog switch disconnects the mobile phone outage.
Wherein, when selecting CPLD to do hardware watchdog, specific requirement according to CPLD, the clear dog signal that mobile phone baseband and radio frequency power amplification modules are regularly met the demands by local bus interface's output, otherwise, surpass the unclear dog of preset time and then export the reset signal of certain time length, when promptly CPLD does not receive dog signal clearly in a period of time to the Enable Pin output reset signal of power analog switch.Described local bus comprises address signal line, data signal line, read line etc., base band and the radio frequency power amplification modules readable clear dog register of writing by write control signal alignment CPLD indoor design writes low level write signal and carries out dog clearly, surpass the unclear dog of preset time and then export the reset signal of certain time length, be CPLD when not receiving dog signal clearly to the Enable Pin output reset signal of power analog switch, reset signal time length can be determined by CPLD.For example clock frequency is 32.768KHZ, and the CPLD hardware watchdog of about 30us of cycle requires the every 240us of external chip to carry out dog clearly, otherwise CPLD output 200ms low level reset signal.Therefore, can be at the CPLD indoor design clear dog register of readable of writing and one 4 digit counter, guarantee per 8 clock cycle, the highest bit position that is counter behind the 240us becomes ' 1 ', if clear dog register bit position is corresponding with the highest bit position of this counter, then need the write signal control line of per 8 clock cycle of base band and radio frequency power amplification modules by local bus to write low level write signal and carry out dog clearly to this clear dog register, counter is counted again, when mobile phone crashes, CPLD does not receive described low level write signal and carries out dog clearly, the low level reset signal of CPLD output 200ms, the mobile phone outage.
Base band and radio frequency power amplification modules are the hardware cores of mobile phone, by cell voltage VBAT1 power supply, export described clear dog signal to hardware watchdog, and stop to export clear dog signal when crashing.This module is the clear dog of hardware watchdog on the one hand, and inside comprises alarm alarm clock control submodule and carries out alarm clock and trigger control and alarm on the other hand, finishes after mobile phone is crashed to restart automatically and alarm.Above-mentioned alarm alarm clock control submodule is on current system time basis, be that alarm clock triggers process continuously with the scheduled duration, crash as the start trigger event up to mobile phone, through after the scheduled duration, mobile phone is finished and is restarted, and after restarting, the UI interface comprises alarm prompt, remind it to carry out illegal operation, reach the purpose of alarm.Above-mentioned scheduled duration needs combined with hardware house dog output reset signal time length and system requirements and decide, comprises that hardware watchdog exports the time of reset signal and the time that mobile phone is restarted automatically.
LDO is an optional function module, and main relevant with the parts selection of hardware watchdog, if cell voltage can guarantee the hardware watchdog operate as normal, then LDO can save; If hardware watchdog is the low-pressure type device, then needing this LDO to change out suitable voltage is the hardware watchdog power supply.
The operation principle of this programme is as follows:
During the mobile phone operate as normal, base band and radio frequency power amplification modules can periodically be exported clear dog signal to hardware watchdog, when hardware watchdog is made up of asic chip, requirement according to asic chip is carried out dog clearly by GPIO mouth output cyclic pulse signal, when hardware watchdog is made up of CPLD, writing clearly according to the requirement of the CPLD low level write signal of write control signal bundle of lines by local bus, the dog register carries out dog clearly, after hardware watchdog is received clearly the dog signal, Enable Pin output high level signal to power analog switch, make the analog switch closure, power supply normally is the mobile phone power supply.
After mobile phone crashes, base band and radio frequency power amplification modules can't be exported clear dog signal to hardware watchdog, hardware watchdog is not received dog signal clearly in a period of time, export the low level reset signal of certain time length to the Enable Pin of power analog switch, analog switch is disconnected, power supply can not normally be mobile phone power supply, mobile phone outage shutdown.
For making mobile phone realize restarting in outage shutdown back, design alarm alarm clock control sub unit makes mobile phone be as the criterion with current system time in base band and the radio frequency power amplification modules, increases continuously scheduled duration, alarms alarm clock control.After mobile phone crashes, reliably cut off the power supply, power up by mobile phone, alarm alarm clock control submodule is finished mobile phone through scheduled duration and is restarted automatically, and is user's display alarm information on the UI interface.
Fig. 2 has shown the method flow diagram that the embodiment of the invention provides, and as shown in Figure 2, step is as follows:
S201: under the mobile phone normal operating conditions, base band and radio frequency power amplification modules are exported clear dog signal to hardware watchdog, are the in time clear dog of hardware watchdog.
S202: the alarm alarm clock control submodule in base band and the radio frequency power amplification modules is as the criterion with current system time, increases continuously scheduled duration, alarms alarm clock control.
S203: judge whether mobile phone crashes.
When hardware watchdog received the clear dog signal of base band and radio frequency power amplification modules, operating handset was normal, carried out step S202 this moment; Otherwise hardware watchdog is not received the clear dog signal of base band and radio frequency power amplification modules, judges that mobile phone crashes, and carries out step S204.
S204: when system in case of system halt, crashing as the start trigger event, the triggering mobile phone is finished and is restarted automatically and alarm after the scheduled duration.
Mobile phone is finished in the back of take place crashing 5 seconds restart automatically and alarmed, alarm alarm clock in base band and radio frequency power amplification modules control submodule needs to increase all the time the triggering process of 5 seconds as alarm clock on the basis of current system time so, when taking place to crash, mobile phone crashes as the start trigger event, after 5 seconds, finish mobile phone and restart automatically, can add alarm prompt at the UI interface after restarting, remind the user to carry out illegal operation, avoid the repetition misoperation to damage mobile phone.Comprise that hardware watchdog output reset signal just reliably disconnects the time of battery supply 5 seconds.
In sum, the present invention is by adopting hardware watchdog technology control power analog switch, when being crashed, mobile phone can cut off the power supply automatically, and trigger to realize that by alarm clock mobile phone restarts automatically and alarm, not only can improve user's satisfaction, can also improve product market competitiveness, save invisible cost.
Although above the present invention is had been described in detail, the invention is not restricted to this, those skilled in the art of the present technique can carry out various modifications according to principle of the present invention.Therefore, all modifications of making according to the principle of the invention all should be understood to fall into protection scope of the present invention.
