During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represent same or analogous key element.Following exemplary embodiment
Described in embodiment do not represent and the consistent all embodiments of the present invention.On the contrary, they be only with it is such as appended
The example of the consistent apparatus and method of some aspects be described in detail in claims, the present invention.
Fig. 1 is a kind of block diagram of assembly detection apparatus according to an exemplary embodiment.What the present embodiment was provided
Assembly detection apparatus, can detect the function for the Devices to test for supporting different fast charge protocols, and will measure the obtained
One electrical data is visual to be supplied to user.As shown in figure 1, the assembly detection apparatus includes：Agreement selecting unit 10, control
Unit 11, sample circuit 12, display screen 13 and Devices to test 14；Wherein, described control unit 11 is selected with the agreement respectively
Unit 10 with, the sample circuit 12, the display screen 13 and the Devices to test 14 electrically connect, the Devices to test 14 with
The sample circuit 12 is electrically connected；Meanwhile, Devices to test 14 is connected with power supply 22.
The agreement selecting unit 10, for the fast charge protocol supported according to the Devices to test 14 to the control
Unit 11 processed exports selection instruction；Described control unit 11, for controlling the Devices to test 14 defeated according to the selection instruction
Go out different first voltages；The sample circuit 12, for gathering the different first voltage, and it is single to be transferred to the control
Member 11, so that described control unit 11 determines whether the function of the Devices to test 14 is different according to the changing rule of first voltage
Often；In the display screen 13, the result whether abnormal for showing the first voltage, the function of the Devices to test 14 extremely
It is few one.
Before the embodiment of the present disclosure is introduced, first the application scenarios that the embodiment of the present disclosure is applicable are introduced：
At present, with the fast development of mobile terminal, various charger being adapted to mobile terminal is occurred in that, it is different

After control unit 11 receives the selection instruction of the transmission of agreement selecting unit 10, control unit 11 knows to be measured set
Standby 14 supported fill agreement soon, then control unit 11 according to the Devices to test 14 supported to fill protocol integrated test system soon to be measured and set
It is standby to export multiple different first voltages, if the function of Devices to test 14 is normal, multiple the first of the output of Devices to test 14
The changing rule of voltage meets the voltage change rule filled soon under agreement that it is supported, if the function of Devices to test 14 is not just
Often, then the changing rule for multiple first voltages that Devices to test 14 is exported is unsatisfactory for its voltage filled soon under agreement change supported
Law.After the control Devices to test 14 of control unit 11 exports multiple first voltages, sample circuit 12 is from Devices to test 14
Multiple first voltages for exporting of voltage output end collection Devices to test 14, and control unit 11 is transferred to, so that control
Unit 11 known according to the changing rule and control unit 11 of first voltage this fill the corresponding normal voltage of agreement soon and change
Rule is contrasted, so that it is determined that whether the function of Devices to test 14 is normal.Meanwhile, MCU111 can by first voltage and
At least one in the whether normal result of function for the Devices to test 14 that MCU111 measurements are obtained is shown to by display screen 13
User.
Optionally, above-mentioned control unit 11 can be single-chip microcomputer, can also be central processor CPU, can also be
MCU111, as long as the control unit 11 can fill agreement soon according to the different protocol integrated test system Devices to tests 14 that fills soon according to different
Export corresponding multiple first voltages.Optionally, above-mentioned sample circuit 12 can be voltage x current sample circuit, this implementation
Example is not limited the physical circuit form of voltage x current sample circuit 12.Optionally, above-mentioned Devices to test 14 can be treated
The charger of survey, can also be data wire to be measured.
Optionally, it is above-mentioned it is to be measured set when being connected with control unit 11, what can be provided by assembly detection apparatus is various
The connecting interface of type is connected with control unit 11, optionally, and various types of connecting interfaces can be different types of USB
Interface, for example including：Micro USB input interfaces, Type-c USB input interfaces, USB male seats input interface and USB female seats are defeated
Outgoing interface etc..
Seen from the above description, the assembly detection apparatus that the embodiment of the present disclosure is provided, control unit can refer to according to selection
The difference of order, control Devices to test exports multiple different first voltages, and whether control unit is by detecting these first voltages
Meet that Devices to test supported fills agreement correspondence normal voltage changing rule soon, whether just to determine the function of Devices to test
Often.I.e. the assembly detection apparatus of the embodiment of the present disclosure, can detect the function for the multiple Devices to tests for supporting difference to fill agreement soon,
User only needs operating protocol selecting unit, and detection process is simple, and without filling the to be measured of agreement soon for each
Equipment sets a kind of detection device, greatly reduces the testing cost of Devices to test.
Fig. 2 is a kind of block diagram of assembly detection apparatus according to another exemplary embodiment.What the present embodiment was related to
It is a kind of possible embodiment of above-mentioned control unit 11.Shown in Figure 2, above-mentioned control unit 11 includes micro-control unit
