High security.
Embodiment three
Fig. 3 is the power control system composition schematic diagram that the embodiment of the present invention three is provided, and refer to Fig. 3, including processor
30th, mobile terminal 10, supply line 40 and detection unit 20, supply line 40 are that mobile terminal 10 carries out factory reset
Power supply, whether detection unit 20 is detected in the corresponding supply line 40 of each mobile terminal 10 electric current, and draws testing result, place
Reason device 30 is controlled according to testing result to the break-make of the supply line 40 of corresponding mobile terminal 10.
In the production process of mobile terminal 10, after every gate inhibition's test is completed, generally require to mobile terminal 10
Carry out the operation of factory reset, make the software program in mobile terminal 10, such as system of dispatching from the factory, prepackage file etc. information
Return to the original state dispatched from the factory.And now, mobile terminal 10 should standard configuration power supply, such as battery, lithium battery, button cell
Deng, it is not assembled together toward contact with mobile terminal 10, or power supply is not powered, then mobile terminal 10 is recovered
The power supply that factory is set is accomplished by being realized by externally fed circuit 40.According to the operating current of mobile terminal 10 and operating voltage
Size, comes to provide electric power for mobile terminal 10 from corresponding dc source.
Mobile terminal 10 can enter off-mode after factory reset completion, now, coupled outside confession
The size in electric line 40 being no electric current, i.e. electric current is zero.Based on this characteristic, by detecting the electricity in supply line 40
The size of stream, it is possible to determine mobile terminal 10 whether be in off-mode, that is, mobile terminal 10 factory reset
Whether complete.
Supply line 40 is arranged at outside mobile terminal 10, and the electric current and voltage using the standard configuration of mobile terminal 10 is mobile terminals
10 power supplies, mobile terminal 10 persistently consumes electric energy during factory reset, after factory reset is completed, mobile whole
End 10 can voluntarily shut down, and then, now can just cut off supply line 40.If cut-out supply line 40 as early as possible, can bring
Certain potential safety hazard；And if shutting off supply line 40 before mobile terminal 10 not yet completes factory reset,
The loss of data in mobile terminal 10 is will result in, the serious mobile terminal 10 that may result in directly is scrapped.
Wherein, the detection unit 20 in the present embodiment, can also include being arranged in the supply line 40 of mobile terminal 10
Microcontroller 21.The effect of microcontroller 21 is the presence or absence of in the electric current in the supply line 40 where real-time detection；Its
In, the power supply for microcontroller 21 itself can be used independently of the power supply beyond the supply line 40, such as button cell, storage
Battery etc., can also be directly using the supply line 40 as the power supply of of microcontroller 21 itself, in this case, when micro-
Electric current in controller 21 is obviously reduced, or microcontroller 21 is powered off, then just it is considered that without electricity in supply line 40
Stream, the factory reset of mobile terminal 10 is completed.
The current conditions of microcontroller 21 in real time in supply line 40, to the feedback signal of processor 30.Work as micro-control
When device 21 processed detects supply line 40 and there is electric current, then to the output signal 1 of processor 30, when microcontroller 21 detects power supply
Circuit 40 is sufficiently small in the absence of electric current, or current value, then to the output signal 0 of processor 30.Processor 30 is then according to microcontroller
The signal that device 21 is exported, is controlled come the break-make of the supply line 40 to corresponding mobile terminal 10.When microcontroller 21 is defeated
When going out signal 1, illustrate there is electric current in now supply line 40, that is, corresponding mobile terminal 10 is carrying out recovery and dispatched from the factory to set
Put and and do not complete, should now continue keep supply line 40 in have electric current, be the continued power of mobile terminal 10；Work as microcontroller
During 21 output signal 0, illustrate there is no electric current in now supply line 40, that is, the recovery of corresponding mobile terminal 10 is dispatched from the factory and set
Put process to have completed, now can then cut off the supply line 40 of the mobile terminal 10.
Further, since generally having multiple mobile terminal 1s 0 on a production line while carrying out factory reset, then, pin
Microcontroller 21 can be respectively provided with to the supply line 40 of each mobile terminal 10, the output result of each microcontroller 21 can be with
It is connected by one-to-many USB port with processor 30, or can also be by exclusive-OR operator, by multiple microcontrollers 21
Output result is exported after XOR.The characteristics of due to XOR is that identical operation result is 0, different computing knots
Fruit is 1, then, when the output result for passing through XOR is signal 1, then explanation has at least one or more mobile whole
Electric current in the supply line 40 at end 10 is zero, and these mobile terminal 1s 0 have been completed factory reset, then can be by this
The supply line 40 of a little mobile terminal 1s 0 cuts off.If transmitting the letter that microcontroller 21 is exported by one-to-many USB port
Number, then many one sides of one-to-many USB port, each port is connected with a microcontroller 21, one one side, with processor
30 are connected, and the output result of each microcontroller 21 is transferred to processor 30 by timesharing.
Above content is to combine specific embodiment further description made for the present invention, it is impossible to assert this hair
Bright specific implementation is confined to these explanations.For general technical staff of the technical field of the invention, do not taking off
On the premise of from present inventive concept, some simple deduction or replace can also be made, the protection of the present invention should be all considered as belonging to
