Description
Technical field
The utility model relates to a kind of pick-up unit, relates in particular to a kind of proving installation that is used for detected electrons equipment USB port performance.
Background technology
At present, have USB (Universal Serial Bus, USB (universal serial bus)) electronic equipments such as computing machine of port are more and more, connect the USB port of electronic equipment when USB device after, electronic equipment has at first detected USB device and has been plugged on its USB port, could realize the data interaction with USB device then.
For guaranteeing USB port energy operate as normal, when electronic equipment factory inspection and daily servicing, often need the plug and play performance of testing USB port.So-called plug and play performance test just is meant that after the USB port of USB device connection electronic equipment, can electronic equipment detect and have USB device.But the specific purpose tool that does not have the testing USB port performance in the prior art, plug and play performance test usually utilize USB device such as the mouse that has USB interface, keyboard, USB flash disk to finish.During use, USB device is inserted each USB port of electronic equipment respectively, check whether autotest program can normally detect the existence of USB device.
Though this method is widely adopted, there is following deficiency:
One, operation inconvenience.Use USB keyboard or USB mouse to test, owing to have line, for operation is made troubles.Simultaneously, because above-mentioned USB device connecting line is longer, when testing a plurality of port electronic equipments such as (have a plurality of USB port usually) computing machines, line easily kinks together, causes that operation is chaotic, process is loaded down with trivial details.
Its two, efficient is low.When needs are tested a plurality of port, if one by one USB keyboard or USB mouse etc. are connected each port, need frequent plug the said equipment in the test process to change port, make the test duration longer, efficient is lower; If simultaneously a plurality of USB keyboards and USB mouse are connected to a plurality of ports, break down, get rid of or need determine it is which port when searching fault, make and search overlong time (especially when line kinks together), cause testing efficiency on the low side equally.
Its three, the cost height.Owing to there is not the specific purpose tool of testing USB port performance in the prior art, the testing tool that adopts is Universal USB equipment such as USB keyboard, USB mouse and USB flash disk, its major function is not the plug and play performance that is used for testing USB port, if above-mentioned USB device only is used for the test port performance, then its major function is not utilized, many electric and mechanical parts are by idle, greatly waste the resource of USB device, cause testing cost higher.
The utility model content
The technical matters that the utility model solves is: a kind of USB port proving installation of simple operation is provided, and it can effectively improve testing efficiency, reduce testing cost.
For this reason, the technical scheme of the utility model technical solution problem is: a kind of USB port proving installation is provided, comprises:
