Abstract

The invention provides a debug indicator light designing method for saving space of a mainboard and belongs to the field of design of server mainboards. The debug indicator light method includes that 14 LEDs are designed to substitute for two-bit eight-segment nixie tubes to save space of the mainboard, and logic states of the LEDs are used for substituting for code display of Debug indicator lights; common-cathode eight-segment nixie tubes are taken as an example, two rows of LEDs, seven of each row, are used for substituting for two-bit eight-section nixie segments for display when circuits of the mainboard are designed, accordingly, space and cost of PCB (printed circuit board) of the mainboard are saved, and space of the mainboard for adding necessary new functions is vacated.

Description

A kind of Debug pilot lamp method for designing of saving mainboard space

Technical field

The present invention relates to server master board design field, specifically a kind of Debug pilot lamp method for designing of saving mainboard space.

Background technology

Mainboard technical development can be said and reach unprecedented performance to today, and also improved greatly in ease for use, from hard wire jumper hard to understand to the flexible jumper being easily understood, can be described as a leap, although domestic consumer can not run into any problem when mainboard is installed, but when using, but often there are some problems, have plenty of that software causes, have plenty of and cause on hardware, it may not be very difficult that these problems solve, and the most difficult is exactly the position of decision problem.

If there is fault in computing machine in the past, the sound that we can only listen PC loudspeaker to send by feat of ear, by feat of different sound, come the position of decision problem, because the miscue that PC loudspeaker send is of a great variety, user remembers difficulty very, this has just formed to general user the obstacle that is difficult to go beyond, add fault prompting that PC loudspeaker send and be not sometimes very accurately, we can not locate abort situation accurately, so even the maintenance personal of specialty also wants the expensive time to check abort situation, but the very large convenience that the appearance of Debug lamp brings to user and maintenance personal, Debug lamp can allow you look for easily out of order position by different pilot lamp combinations, and very accurately, without carrying out any examining, just can keep in repair.

As the Debug pilot lamp of mainboard, for the assurance debug stage can judge which code self check code is parked in intuitively, so that by Code location problem place.But, in high density server motherboard design process, there is to strict restriction in the space of mainboard PCB; When mainboard size determines, when needs increase some functions, tend to occur that components and parts do not have the problem of space arrangement, once add again two eight segment numeral pipes (the PCB area generally taking is larger) on this mainboard, for showing self check code, just need to give up necessary function.

Summary of the invention

For overcoming the above problems, in limited space, take into account the advantage that Debug analyzes that is easy to of this class high density mainboard, can retain again the necessary function of mainboard, a kind of Debug pilot lamp method for designing of saving mainboard space is proposed herein.

The present invention proposes a kind of Debug pilot lamp method for designing of saving mainboard space.Main thought is: by designing 14 light emitting diodes, substitute two 8 segment numeral pipes, carry out the self check code of identification mainboard, to save PCB space and the cost of mainboard, for mainboard adds necessary new function vacating space.

In 28 segment numeral pipes, the anode pin that pin pin a, b, c, d, e, f, g, h are every section of LED; DG1 and DG2 are followed successively by the common cathode of figure case 1, figure case 2.

According to the principle of 1 common cathode 8 segment numeral pipe, when this part circuit design of mainboard, can be with two discharge optical diodes, 7 of every rows, the digital section substituting in 28 segment numeral pipes shows.That is:

First row: LED1, LED2, LED3, LED4, LED5, LED6, LED7

Substitution number code bit 1 section: a1, b1, c1, d1, e1, f1, g1

Second row: LED8, LED8, LED10, LED11, LED12, LED13, LED14

Substitution number code bit 2 section: a2, b2, c2, d2, e2, f2, g2.

The invention has the beneficial effects as follows:

1), the present invention proposes a kind of Debug pilot lamp method for designing of saving mainboard space, notable feature 1 is to substitute two 8 segment numeral pipes by designing 14 light emitting diodes, saves the space of mainboard;

2), the present invention proposes a kind of method for designing that server power supply module is general that realizes, notable feature 2 is the logic states with 14 light emitting diodes, the code that substitutes Debug pilot lamp shows;

3), the present invention proposes a kind of method for designing that server power supply module is general that realizes, notable feature 3 is to substitute two 8 segment numeral pipes by designing 14 light emitting diodes, on mainboard, after amount, can to a certain degree reduce costs the competitive power of improving product.

Accompanying drawing explanation

Fig. 1 is 8 segment numeral pipe schematic diagram of standard.

Fig. 2 is the schematic diagram of 1 common cathode 8 segment numeral pipe.

Embodiment

Figure 1 shows that the 8 segment numeral pipe schematic diagram (the common cathode 8 end charactrons of take are example) of standard:

Fig. 1 is 28 segment numeral pipes, the anode pin that pin pin a, b, c, d, e, f, g, h are every section of LED; DG1 and DG2 are followed successively by the common cathode of figure case 1, figure case 2.

For the situation that realizes of this method for designing is clearly described, in conjunction with Fig. 1, Fig. 2, performing step is described.Specific as follows:

1), when mainboard Debug pilot lamp line design, the alternative figure case 1 of digital pilot lamp and the LED of figure case 2 are lined up to two rows;

2), 7 signal a, b, c, d, e, f, g controlling two 8 segment numeral pilot lamp are connected in turn to the anode of first row LED:LED1, LED2, LED3, LED4, LED5, LED6, LED7;

3), the negative electrode of first row LED:LED1, LED2, LED3, LED4, LED5, LED6, LED7 is connected together, and be connected with the gating signal DG1 of figure case 1;

4), 7 signal a, b, c, d, e, f, g controlling two 8 segment numeral pilot lamp are connected in turn to the anode of second row LED:LED8, LED9, LED10, LED11, LED12, LED13, LED14;

5), the negative electrode of second row LED:LED8, LED9, LED10, LED11, LED12, LED13, LED14 is connected together, and be connected with the gating signal DG1 of figure case 2;

Can realize like this with the 0603 LED lamp encapsulating of 14 pasters and substitute double figures code pipe demonstration self check code.When code is parked in a certain state, can light, extinguish the tens digit that state show that every row is corresponding by what judge two row LED, finally determine which code self check code is parked on, so that orientation problem place.

In sum, by design, control 14 light emitting diodes and substitute two 8 segment numeral pipes and show, carry out the self check code of identification mainboard, can save PCB space and the cost of mainboard, and add necessary function vacating space for mainboard.
