Abstract
The utility model discloses a kind of Multifunctional main board diagnostic card, comprise one with the diagnostic module of Presentation Function; TTL/CMOS level conversion is become to meet the level switch module of RS232 specification output level by one; And a BIOS debugging module.Not only cost is low for the utility model, volume is little, and feature richness, can meet the major part debugging of mainboard, diagnosis and detection demand.
Description
Technical field
The utility model relates to a kind of Multifunctional main board diagnostic card with digital display function.
Background technology
Mainboard is the core component of computer, it is assembled with multiple operation element, such as CPU, sound card, network interface card, internal memory etc.When certain element cannot normally work, which usually need to adopt Post Card to occur problem to diagnose module of mainboard, and existing Post Card is single display diagnostic message, without other function, purposes is more single, cannot meet the demand of user.And the chip package that existing Post Card adopts is large, is difficult to be integrated on the PCB of the full card size of mini-PCIE; Thus cost is high, be also difficult to other function integrated more simultaneously.
Summary of the invention
The purpose of this utility model is the defect existed for above-mentioned prior art, a kind of Multifunctional main board diagnostic card is provided, comprise one with the diagnostic module of Presentation Function, TTL/CMOS level conversion is the level switch module meeting RS232 specification output level by one, and a BIOS debugging module debugged for software engineer.
In the technical program, described BIOS debugging module comprises the BIOS deck be arranged on for grafting mainboard BIOS ROM on Post Card, and described BIOS debugging module is electrically connected with mainboard by BIOS H1 interface.
All device layouts on the PCB of the full card size of the mini-PCIe of standard, with mini-PCIe interface, the mainboard that directly can be inserted into band mini-PCIe connector use by the utility model
In a specific embodiment of the technical program, diagnostic module adopt model be the chip of AK2001 as coding chip, described coding chip utilizes the BIOS built in self testing program of mainboard to obtain testing result, and shows failure message.
The utility model have employed the main chip of coding chip AK2001 chip as digital Post Card, make that the cost of Post Card is lower, volume is less, and there is unnecessary space to carry out Function Extension, the utility model also add level conversion function and the BIOS debug function of different agreement on Post Card originally, makes function more rich and variedization of Post Card.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the circuit diagram of the utility model diagnostic module;
Fig. 3 is the circuit diagram of the utility model level switch module;
Fig. 4 is the circuit diagram of the utility model BIOS debugging module.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the Multifunctional main board diagnostic card that the utility model one embodiment proposes, comprise the diagnostic module 3 of band Presentation Function, BIOS debugging module 1 and level switch module 2, make Post Card be no longer single diagnostic message display card, and BIOS debugging can also be carried out and change different level.In addition, the utility model is also provided with Mini PCIe interface 4, can be connected on the mainboard of various band Mini PCIe, realize several functions.
As shown in Figure 2, diagnostic module of the present utility model adopts model to be that the chip of AK2001 is as coding chip, this chip is more much smaller than the volume of the chip that existing Post Card adopts, purchase cost is also low simultaneously, the production cost of Post Card is also significantly declined, owing to have employed the little AK2001 chip of volume, space unnecessary on Post Card is made to carry out other Function Extensions, and the overall volume of Post Card have also been obtained effective control, coding chip AK2001 chip utilizes the BIOS built in self testing program of mainboard to obtain testing result, and show failure message.
As shown in Figure 3, except basic diagnostic message Presentation Function, the utility model also add a level switch module, TTL/CMOS level conversion is the output level meeting RS232 specification by this module, this module is by COM_H1 interface incoming level, transformed by 1 IC, and then the level meeting RS232 specification is exported by COM_H2 interface.
As shown in Figure 4, BIOS debugging module of the present utility model comprises the BIOS deck be arranged on for grafting mainboard BIOS ROM on Post Card, and described BIOS debugging module is electrically connected with mainboard by BIOS H1 interface.
Above specific embodiment is only in order to illustrate design of the present utility model, and those of ordinary skill in the art can make various deformation and change under design of the present utility model, and these distortion and change include within protection domain of the present utility model.
