Fig. 2 show the flow chart of the hardware fault detection method of the intelligent terminal of one embodiment of the invention.Such as Fig. 2 institute
Show, in one embodiment of the invention, the hardware fault detection method of intelligent terminal includes the following steps:
S101 judges in multiple predetermined hardware modules of the intelligent terminal with the presence or absence of the hardware module to break down；
In this step, the multiple pre- of intelligent terminal can be judged by judging the case where intelligent terminal consumes electric current
If whether thering is hardware module to break down in hardware module.
For example, when user feels that exception occurs in intelligent terminal hardware state in intelligent terminal use process, for example encounter
Electric quantity consumption is too fast, and stand-by time shortens, and charging rate is slack-off, make a phone call fever etc. scenes when, it can be determined that in intelligent terminal
Multiple predetermined hardware modules in have the hardware module to break down.
For another example can be determined in step s101 by following sub-step in multiple predetermined hardware modules of intelligent terminal
Whether there is hardware module to break down:
S11: the actual current value and theoretical current value under standby mode in the electric network of the intelligent terminal are obtained；
In this sub-step, such as user opens the hardware module on intelligent terminal and detects program (App), intelligent terminal
On processor 60 be waken up after, the size of current on current sampling unit 20 is read by Power Management Unit 50, is obtained
Current value on the entire electric network of intelligent terminal.Under ideal case, Power Management Unit 50 can when will be standby power supply it is single
Current value I01 in member 10 is read and is stored in the register (not shown) of intelligent terminal, register or other storages
The normal Standby current value under standby mode in the electric network of intelligent terminal, i.e. theoretical current value I0 are stored in device simultaneously.
S12: judge whether the actual current value and the difference of the theoretical current value are greater than the second preset difference value；
Processor 60 by from register come the actual current in the electric network of the intelligent terminal under the standby mode that reads
Value I01 is compared with theoretical current value I0, and whether judgement (I01-I0) is greater than the second preset difference value.
S13: when the difference of the actual current value and the theoretical current value is greater than second preset difference value, judgement institute
State the hardware module for existing in multiple predetermined hardware modules of intelligent terminal and breaking down.
In this step, it when (I01-I0) this difference is greater than the second preset difference value I02 of setting, then can be determined that
There is the hardware module to break down in multiple predetermined hardware modules of intelligent terminal.
After sub-step S12, when judging the difference of actual current value and the theoretical current value no more than described the
Two preset difference values determine that having no hardware module in the intelligent terminal breaks down, then end fault detection process.
When judging there is the hardware module to break down, step S102 is executed, cuts off multiple predetermined hardware modules in turn
Each of first kind hardware module power supply；
In this step, multiple load switch S1-S4 on supply network can be controlled by processor 60 to break in turn
It opens；Such as switching off load switch S1, S2, S3 in turn.
Later, step S103 is executed, in the standby state, obtains cut off each first kind hardware module respectively
Present current value after power supply in the electric network of the intelligent terminal；
In this step, during the hardware intelligent measurement, the normal fortune that S1-S3 has no effect on intelligent terminal is disconnected
Row.After turning off a load switch every time, processor 60 enters standby mode by intelligent terminal into suspend mode, and utilizes power supply
Administrative unit 50 reads the present current value on supply network respectively, is denoted as I1, I2, I3.In the examples described above, present current value
I1 represents switching off load switch S1 and closes present current value after radio frequency power amplification module 31 on electric network；Current flow
Value I2 represents the present current value after switching off load switch S2 i.e. charge closing circuit module 32 on electric network；Present current value I3
It represents switching off load switch S3 and closes present current value after sensor module 33 on electric network.
Later, step S104 is executed, the theoretical current value under standby mode in the electric network of the intelligent terminal is obtained, and
Judge whether each described present current value is less than corresponding first preset difference value with the difference of the theoretical current value；
In this step, multiple theoretical current value I0 available first, then by each present current value I1, I2,
I3 compared with theoretical current value I0, obtains multiple differences (I1-I0), (I2-I0) and (I3-I0) respectively.Judge that these are poor respectively
Whether value is less than the corresponding first preset difference value I03 of each difference (I1-I0), (I2-I0) or (I3-I0).The step for
In, the first preset difference value I03 can be set by developer or user.And each difference (I1-I0), (I2-I0)
(I3-I0) can respectively correspond different differences, such as the corresponding preset difference value of difference (I1-I0), and difference (I2-I0) corresponds to pre-
If difference I03 " etc. or difference (I1-I0), (I2-I0) and (I3-I0) can correspond to identical difference.
Later, step S105 is executed, when one of them described present current value and the difference of the theoretical current value are less than
Corresponding first preset difference value determines that the first kind hardware module of the corresponding present current value breaks down；
Such as: if (I1-I0) is less than corresponding first preset difference value I03, determine that failure occurs in load switch S1
On corresponding access, i.e., radio frequency power amplification module 31 breaks down；If (I2-I0) is less than corresponding first preset difference value
I03 then determines that failure occurs on the corresponding access of load switch S2, i.e., charging circuit module 32 breaks down；If (I3-
I0) it is less than corresponding first preset difference value I03, then determines that failure occurs on the corresponding access of load switch S3, i.e. sensor
Module 33 breaks down.
If difference (I1-T0) is greater than the first preset difference value I03, leak current fault is judged not and is leading to where switch S1
Then road needs to re-close load switch S1, and disconnects load switch S2, repeat the detection process.By the above method,
The fault condition of the hardware module on electric network can be judged one by one.
By the above method, the detection of intelligence can be carried out for above-mentioned third class hardware fault, intelligent terminal is allowed to carry out

Measured hardware module to break down, thened follow the steps S102 to S104, when and hardware module be not detected broken down, then
End fault detection process.
After executing step S102 to S104, when determining each present current value and theoretical current value in step s105
Difference is not less than corresponding first preset difference value, then determines in multiple predetermined hardware modules of the intelligent terminal one or more
A second class hardware module breaks down.Specific in embodiment, if determining peripheral hardware after load switch S1 to S3 is successively disconnected
The equal fault-free of module such as radio frequency power amplification module 31, charging circuit module 32 and sensor module 33, then may be used in module
To determine that the corresponding access of load switch S4 breaks down.
Later, following steps are executed:
Step S107: the power supply of each the second class hardware module is cut off in turn；
In the present embodiment, in conjunction with shown in Fig. 1 and Fig. 3, since Power Management Unit 50 includes for controlling each
State the load switch that the second class hardware module opens or closes, which for example can be contact, then can be by with the
The identical testing principle of a kind of hardware module realize to current monitor module 34, LCD MODULE 35, touch sensitive surface module 36,
The equal second class hardware module of camera module 37 carries out fault detection.
Each load switch S5, S6, S7, S8 in Power Management Unit 50, wheel can be controlled by processor 60 at this time
Stream turns off load switch S5-S8, cuts off the power supply of each the second hardware module.
Step S108: it in the standby state, obtains respectively described after cutting off each described second class hardware module power supply
Present current value in the electric network of intelligent terminal；
Turning off a load switch preprocessor 60 enters standby mode by intelligent terminal into suspend mode every time, and controls
Power Management Unit 50 reads the present current value on supply network respectively, is denoted as I5, I6, I7, I8.During this,
In cutting load switch S5 and records I5 and then be closed load switch S5, cut off load switch S6 and record I6, i.e., it is each
A switch is cut off in turn, after recording corresponding present current value, is closed the switch, then cut off another switch.
In the above-described example, present current value I5 represents switching off load switch S5 and closes after current monitor module 34
Present current value on supply network；Present current value I6 represents switching off load switch S6 and closes after LCD MODULE 35
Present current value on supply network；Present current value I7 is represented after switching off load switch S7 closes touch sensitive surface module 36 and is supplied
Present current value on electric network；Present current value I8 is represented after switching off load switch S8 closes camera module 37 and is powered
Present current value on network.
Step S109: the theoretical current value under standby mode in the electric network of the intelligent terminal is obtained, and is judged each
Whether a present current value is less than corresponding third preset difference value with the difference of the theoretical current value；
In this step, it by each present current value I5, I6, I7, I8 respectively compared with theoretical current value I0, obtains
Multiple differences (I5-I0), (I6-I0), (I7-I0) and (I8-I0).Judge whether these differences are less than third preset difference value respectively
I04.In this step, third preset difference value I04 can be set by developer or user.Each difference (I5-I0),
(I6-I0), (I7-I0) and (I8-I0) can correspond to identical third preset difference value I04, and it is pre- can also to correspond to different thirds
If difference I04.
Step S110: when one of present current value is default less than corresponding third with the difference of the theoretical current value
Difference determines that the second class hardware module of the corresponding present current value breaks down.
For example, being judged as that leak current fault generation is loading if (I5-I0) is less than corresponding third preset difference value I04
On the corresponding access of switch S5, i.e., leak current fault occurs for current monitor module 34；If it is pre- that (I6-I0) is less than corresponding third
If difference I04, then it is judged as that leak current fault occurs on the corresponding access of load switch S6, i.e., LCD MODULE 35 leaks
Electric fault；If (I7-I0) is less than corresponding third preset difference value I04, it is judged as that leak current fault occurs in load switch S7
On corresponding access, i.e., leak current fault occurs for touch sensitive surface module 36；If (I8-I0) is less than corresponding third preset difference value I04,
Then it is judged as that leak current fault occurs on the corresponding access of load switch S8, i.e., leak current fault occurs for camera module 37.
