Description
Technical field
The utility model relates to the computer hardware pick-up unit, especially the keyboard and mouse pick-up unit.
Background technology
When buying keyboard or mouse, generally just exterior of commodity is carried out preliminary inspection, the quality of wanting to check thoroughly keyboard or mouse can only connect on computers, so just very inconvenient, do the businessman of second-hand sales for those, this test mode is more impracticable, waste time and energy, and efficient is low.
Summary of the invention
Technical assignment of the present utility model is a kind of keyboard and mouse pick-up unit that provides for above the deficiencies in the prior art.
The technical scheme that its technical matters that solves the utility model adopts is: the keyboard and mouse pick-up unit, comprise MCU, this MCU is connected with power circuit, display circuit, warning circuit, control circuit and interface circuit, is provided with PS/2 interface and USB interface at described interface circuit.
Described display circuit is connected with display, is used for showing current test mode.
Described warning circuit is connected with warning horn, can send different prompt tones according to the result of test.
The utility model has the advantage of simple in structure, processing ease, easy to carry, cheap, detect accurately, speed is fast, efficient is high, can alleviate operating personnel's labour intensity.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with Figure of description the utility model is done following detailed theory.
As shown in the figure, the keyboard and mouse pick-up unit comprises MCU, and this MCU is connected with power circuit, display circuit, warning circuit, control circuit and interface circuit, is provided with PS/2 interface and USB interface at described interface circuit.
Described display circuit is connected with display, is used for showing current test mode.
Described warning circuit is connected with warning horn, can send different prompt tones according to the result of test.
Its principle of work is: when detecting keyboard, type according to keyboard is connected on the corresponding PS/2 interface of pick-up unit or the USB interface first, select again the test on the control circuit, begin keyboard is detected, system at first detects the connection status of keyboard, if connect normal, Caps Lock on the keyboard and Num Lock pilot lamp can glimmer, display shows successful connection simultaneously, if still can't detect keyboard after 5 seconds, then display shows connection failure, and lists the reason of connection failure, and warning horn can send different prompt tones according to connection result; After successful connection, the button on the keyboard all can show at display, if there is button to damage, then with display on corresponding character color dimmed, withdrawing from the selection control circuit namely finishes the test to keyboard.
When detecting mouse, type according to mouse is connected on the corresponding PS/2 interface of pick-up unit or the USB interface first, select the test on the control circuit again, begin mouse is detected, system at first detects the connection status of mouse, as connect normal, display shows successful connection, if still can't detect mouse after 5 seconds, then display shows connection failure, and list the reason of connection failure, warning horn can send different prompt tones according to connection result; After successful connection, the right and left key of clicking the mouse, display shows corresponding right and left key, the roll mouse roller, display shows the arrow of scroll-up/down, selects withdrawing from the control circuit, namely finishes the test to mouse.
