For making the purpose of the present invention, technical scheme and advantage clearer, clear and definite, the present invention is described in more detail for the embodiment that develops simultaneously referring to the drawings.Should be appreciated that specific embodiment described herein is used only for explaining the present invention, be not intended to limit the present invention.
A kind of method that the invention provides starting up of terminal and identification memory card synchronous operation, as it is shown in figure 1, said method comprising the steps of:
S1, when starting up of terminal signal being detected, send simulation clock signal to memory card module, trigger memory card module and enter duty, send simultaneously and detect storage card status signal to power management module.
After starting up of terminal signal being detected, then the simulation clock signal generation module by presetting occurs simulation clock signal to memory card module, triggers memory card module and enters duty.Owing to intelligent terminal is when starting boot program, central processing unit needs first to start its work, the clock activating signal memory card module that then can not export memory card module enters the state of preparation, then need to preset a simulation clock generation unit, by described simulation clock generation unit transmission simulation clock signal SDCLK to memory card module, wake up memory card module up and enter the state of preparation.
After simulation clock signal tranmitting data register signal to memory card module, the most described power management module also receives the detection signal of the detection storage card state sent from storage card state detection unit, triggers it and detects the running status that storage card is current.
After S2, described power management module receive described detection storage card status signal, send voltage detection signal to memory card module, and judge that the loop state of currently stored card module is off state or channel status according to the voltage detection signal returned.
After described power management module receives detection storage card status signal, just voltage detection signal is sent to memory card module, by the voltage status to memory card module, judge that it is presently in obtaining state, concrete, the current state of memory card module is that insert state still extracts state, owing to being inserted into the storage card installing port of terminal when memory card module, it is after it powers at power management module, the loop state of memory card module is channel status, and when memory card module is in the state of extracting, it is not mounted in storage card installing port, then the loop state of memory card module is off state, therefore can be by the judgement to storage card loop state, get its plug state.
S3, identify currently stored card according to the loop state judged and be in insert state and still extract state, and control to stop sending detection storage card status signal to power management module.
For the foregoing reasons, in this step, it is in open circuit or path according to loop state, it is determined that go out the plug state of memory card module, and return recognition result.
Described step S2 includes:
S21, detecting the loop current signals of currently stored card module, if detecting, then judging that the loop of currently stored card module is in channel status；Otherwise, it is determined that the loop of currently stored card module is in off state.
Further comprise the steps of: after described step S3
S4, after the signal that starting up of terminal completes being detected, control stop send simulation clock signal to memory card module.
After starting up of terminal completes, the identification of storage card can be realized by central processing unit, and read its information stored, therefore complete when starting up of terminal, control simulation clock signal sending module stopping transmission simulation clock signal is to memory card module, and its working is by central processing unit control.
In order to realize the accurate detection to starting up of terminal signal, described step S1 includes step:
S11, when starting up of terminal level signal output low level being detected, it is determined that terminal is in startup open state.
Additionally, further comprise the steps of: in described step S2
After S21, power management module receive detection storage card state detection signal, power for memory card module.
Power management module is while powering for memory card module, and also transmission detection signal is to memory card module, detects its running status.
Below as a example by its specific embodiment, the method for the invention is provided more detailed description.
In order to obtain the starting-up signal of terminal accurately, in the specific implementation, level detection unit, detection intelligent terminal start level signal power on signal can be set.When starting intelligent terminal boot program, this level signal power on signal is low level state.
Simulation clock signal SDCLK that simulation clock generation unit produces is used for waking up up memory card module, enters the state of preparation.This simulation clock signal SDCLK is the clock signal that simulation central processing unit is sent to memory card module, owing to intelligent mobile terminal is when starting boot program, central processing unit needs first to start its work, then can not export the clock signal of memory card module, the state of preparation is entered for activating memory card module, then needing to arrange simulation clock generation unit, transmission simulation clock signal SDCLK, to memory card module, wakes up memory card module up and enters the state of preparation.
As in figure 2 it is shown, when level detection unit detects intelligent terminal start level signal power
When on signal is low level, level detection unit transmission level signal gives simulation clock generation unit, activates simulation clock generation unit work.Simulation clock generation unit output simulation clock signal SDCLK, to memory card module, wakes up memory card module up and enters the state of preparation.
When level detection unit detects that intelligent terminal start level signal power on signal is low level, level detection unit transmission level signal is to memory card module instruction detection unit, memory card module instruction detection unit sends the detection signal instruction of memory card module to power management module, then power management module voltage sense signal is to memory card module, there is provided memory card module supply voltage signal, then memory card module possesses the condition entering duty.Arrange herein power management module output voltage signal to memory card module, this supply voltage signal possess detection memory card module state effect.
As it is shown on figure 3, owing to intelligent terminal is when starting start, its power supply of power management module Rapid reset, restart output each road supply voltage signal.It is thus desirable to arrange detection status information sending module, the detection signal instruction of memory card module is sent to power management module by described detection status information sending module, the detection command signal that power management module sends according to memory card module instruction detection unit, voltage sense signal is to memory card module, on the one hand detect the state of memory card module, on the other hand power to memory card module.
If memory card module instruction detection unit often sends a storage card detection signal instruction to power management module, power management module correspondingly exports primary voltage detection signal and possesses the condition of detection memory card module state to memory card module, the then voltage signal that power management module exports.If at interval of storage card detection signal instruction of 1s memory card module instruction detection unit transmission to power management module, then power management module is at interval of 1s output primary voltage detection signal to memory card module, detects the state of memory card module.
Concrete, in specific implementation process, the loop current of memory card module by arranging current impulse detector unit, can be detected, it is judged that storage card is to insert or extract state.When memory card module is insert state, the voltage signal of power management module output is to memory card module, this voltage signal loop by memory card module, then current impulse detector unit detects current pulse signal, then judges there is the electric current loop by memory card module.The voltage detection signal of now power management module output completes the state-detection to memory card module, and then as the supply voltage signal of memory card module.Then power management module terminates detecting memory card module instruction detection unit transmission the response of signal instruction, then memory card module instruction detection unit stops sending detection signal instruction to power management module.
When memory card module is for extracting state, then the loop state of memory card module is off state, when then the voltage signal of power management module output is to memory card module, current impulse detector unit can not detect the current pulse signal on memory card module loop, then judge do not have the electric current loop by memory card module.The state of memory card module is detected by the voltage signal of now power management module output as detection signal.Then memory card module instruction detection unit is at interval of 1s transmission detection command signal to power management module, and power management module sends voltage detection signal to memory card module.
Finally, as shown in Figure 4, when intelligent mobile terminal has been started shooting, level detection unit transmission level signal gives simulation clock generation unit, simulation clock generation unit stopping output simulation clock signal SDCLK is to memory card module, the clock signal of central processing unit output memory card module, and central processing unit and memory card module carry out communication, the state of memory card module entrance work, then realize intelligent mobile terminal start Tong Bu with identification memory card.
