Summary of the invention
The purpose of this utility model is to provide a kind of and two kinds of proving installations that test action is switched of AGP SLOT and VGA ON BOARD can be made it can carry out the priority test, thereby two kinds of test jobs are finished in proper order.
Proving installation provided by the utility model includes: an AGP interface, a VGA ON BOARD interface, one output interface that outputs test result, a control circuit that sends control signal, be used for controlling the switching that commutation circuit is carried out test signal, and a commutation circuit, being controlled by control circuit, the signal that sends according to control circuit makes corresponding change action and a subscriber switch is used to send test enable signals.
AGP interface, VGA ON BOARD interface and output circuit three ends are connected with each other, and join with commutation circuit again simultaneously, and commutation circuit connects control circuit, and control circuit links to each other with subscriber switch, controlled by subscriber switch.
Principle of work of the present utility model is that control circuit reads the signal that subscriber switch sends, judge testing sequence, and then driving commutation circuit action, commutation circuit selects test interface to test, realize the switching of AGP interface and VGA ON BOARD interface, the last test result exports display to via output interface, thereby finishes the switch test function.

Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
At first see also Fig. 1, proving installation disclosed according to the present invention includes AGP interface 10, VGA ON BOARD interface 11 connects the output interface 12 of display Monitor, the commutation circuit of being made up of two relays 13, control circuit 15, and subscriber switch 16.
AGP interface 10 links to each other with commutation circuit 13 with VGA ON BOARD interface 11, control circuit 15 sends control signal commutation circuit 13 is controlled, commutation circuit 13 is moved according to the signal that control circuit 15 sends, and realizes the switching of test, at last test result is exported through output interface 12.
Commutation circuit is made up of two relays, i.e. first relay 131 among Fig. 2 and second relay 132.Control circuit is made up of power supply and control IC, and control IC is made of single-chip microcomputer and data latches, and data latches is conventional 743 serial integrated circuit, and as 743LS373, data latches connects single-chip microcomputer, is subjected to Single-chip Controlling.
Wherein also be connected with an indicator contact 14 between two of first relay 131 switching pins (the 1st pin and the 16th pin), be used for link indicator, indicator is made of a resistance in series and a light emitting diode.
Fig. 2 is the circuit diagram of the whole test process of an embodiment of the present utility model.First relay 131 contains eight pins, comprising four input pins, two output connecting pins, also has two to be to switch pin.Four input pins are divided into two groups, and one group is the 6th pin and the 11st pin, and another group is the 9th pin and the 8th pin.First group of the 6th pin links to each other with AGP interface 10 with the 11st pin, and another is organized the 9th pin and links to each other with VGA ON BOARD interface 11 with the 8th pin.Two output connecting pins 4 are connected with the 14th pin with the 13rd pin of output interface 12 with 13.The 1st pin of the 1st pin of first relay 131 and second relay 132,3 of the 6th pins have been connected in together, their ends all link to each other with the 20th pin of control circuit 15, the direct supply of the 20th pin is powered to it, and the other end links to each other with the subscriber switch button; One end of the 8th pin of second relay 132 links to each other with two pins of control circuit, and the other end links to each other with the subscriber switch button equally.
When test, earlier the AGP card of preparing to test is inserted AGP interface 10, VGA ON BOARD inserts VGA ON BOARD interface 11, and output interface connects display simultaneously.First button 161 that the user presses subscriber switch 16 sends enabling signal, the the 1st, the 6th pin of the 1st pin of turn-on relay 13, relay 14, be connected with the 20th pin of control circuit 15, the vertical-horizontal signal that this moment, relay 13 cut off VGA ON BOARD, carry out the test of AGP card, the vertical-horizontal signal of AGP card exports display to via initiating signal.Press second button 162 of subscriber switch 16 as the user, then start test to VGA ON BOARD, the 8th pin of enabling signal conducting this moment second relay 132, control signal exports the 3rd pin to, notify the 2nd pin to send switch-over control signal, the 16th pin of conducting first relay 131 and second relay 132, and indicator contact 14, (led lighting after the indicator conducting), control signal drive first relay 131 and the action of second relay 132 and finish test to VGA ON BOARD.The user learns to test by the auxiliary demonstration of indicator and finishes, carries out the next round test then.
The switch test device of AGP SLOT disclosed according to the present invention and VGA ON BOARD, the test action of AGP SLOT and VGA ON BOARD is finished in proper order, need not switching on and shutting down again, need not to plug once more the AGP card, more need not the handoff functionality device, thereby operate more convenient, saved the test duration, also reduced wearing and tearing, not only saved cost but also improved testing efficiency proving installation, especially be applied to the large batch of test of production line, advantage wherein is more obvious.
