In the embodiment of the present invention, the test equipment can be polytype tools such as desktop computer, notebook computer
There is the test equipment of USB interface, the external power source specifically refers to programmable power supply.If by the test equipment to the electric current of terminal
Tested, then to meet that test equipment and external power source are both needed to be connected with terminal, in addition, test equipment also needs to connect by GPIB
Connect and be connected with external power source, so, after successful connection, under the control of test equipment, it is terminal that terminal, which will be switched off internal battery,
The power supply of mainboard, should be to be that terminal mainboard is powered by external power source, in this way, test equipment, which passes through GPIB connections, reads external electrical
The output current in source, you can test obtains the size of current of terminal.
In specific application scenarios, test computer and programmable power supply passes through a test adaptor head and the USB of terminal
Type C interface is connected, and then test adaptor head is connected with the USB type-C interfaces of terminal again.Specifically, test computer
The 5V power supplys of USB interface pass through test adaptor head and the first pin (i.e. auxiliary signal pin of terminal USB type-C interfaces
SBU1 or SBU2) it is connected, the data control line D+/D- for testing the USB interface of computer passes through test adaptor head and the USB of terminal
The 4th pin (i.e. D+ with D- pins) of type-C interfaces is connected, the first output port of programmable power supply by test adaptor head with
Second pin (i.e. Tx+ with Tx- pins) on terminal USB type-C interfaces is connected, and the second output port of programmable power supply passes through
Test adaptor head is connected with the 3rd pin (i.e. VBUS pins) on terminal USB type-C interfaces.
In this way, work as the auxiliary signal pin of the 5V power supplys of the USB interface of test computer and the USB type-C interfaces of terminal
After SBU1 or SBU2 is connected, the current potential on the auxiliary quotation marks pin will be because becoming high electricity being connected to the 5V power supplys of test computer
Position, i.e. power down control signal become high level, the switching device shut-off in the first power supply circuit, so as to cut off the built-in of terminal
Battery is the power supply of terminal mainboard.Now, due to Tx+ the and Tx- pins and programmable power supply on the USB type-C interfaces of terminal
The first output port be connected, Tx+ the and Tx- pins on terminal inner, the USB type-C interfaces of terminal again with second supply
Circuit is connected, and so while the power supply of terminal built-in battery is cut off, the power switching of terminal mainboard is to be supplied by second
The first output port power supply of the programmable power supply of circuit connection.
Further, since second output port phase of the VBUS pins also with programmable power supply on the USB type-C interfaces of terminal
Even, due to the presence of the second output port, then the dependence test software for coordinating terminal inner to install, terminal will be caused to be triggered out
Machine.After terminal is successfully started shooting, test computer passes through the data control line D+/D- of its USB interface and the USB type-C of terminal
The connection of the Tx+ and Tx- pins of interface, send and order to terminal mainboard, so that terminal enters corresponding test pattern.It is same with this
When, test computer is connected by the GPIB with programmable power supply, closes the second output port of programmable power supply, in order to avoid programmable power supply
The electric current of second output port output influences the accuracy of terminal current test.Afterwards, test computer can by with program-controlled electric
The GPIB connections in source, the electric current of the first output port output of programmable power supply is read, learn the static current of lcd situation of terminal.
It can be seen that using the test system and correlation technique that are provided in the embodiment of the present invention, pass through the power supply to terminal inner
Circuit is improved, and the current potential of the auxiliary signal pin of the USB type-C interfaces of terminal is configured into power down control signal,
On the premise of machine is not torn open, do not destroy the complete machine surface structure of terminal, do not influence terminal normal work, so that it may to all kinds of of terminal
State current is tested, and the outgoing of the terminal of plant produced has been effectively ensured.
