The utility model content
The utility model is in order to overcome above-mentioned defective of the prior art; A kind of desktop computer computer interface Circuit Emulation Service plate is provided; It can complete analogue computer mainboard the function of interface circuit; Detection interface to main components and parts also is provided, has been convenient to the teaching and the exercise of the maintenance of computer main board chip-scale.
For realizing above-mentioned purpose, the openly following technical scheme of the utility model:
A kind of desktop computer computer interface Circuit Emulation Service plate comprises the interface circuit emulation module, detects interface module and power module, and wherein: said interface circuit emulation module is simulated the function of desk-top dynamo-electric brain mainboard interface circuit; Said detection interface module is communicated by letter with said interface circuit emulation module and is connected; Gather the running state information of the components and parts to be detected in the said interface circuit emulation module and outwards output, receive the command signal and the drive signal of external unit and send said interface circuit emulation module to.
Preferably, also be provided with an electromotion pilot lamp, a functional switch button and a start pilot lamp on the said interface circuit emulation module.
Preferably, said detection interface module comprises two 40PIN line interfaces.
Preferably, said power module is the 9V direct supply.
Preferably, said desktop computer computer interface Circuit Emulation Service plate adopts double-deck pcb board as circuit substrate.
Compared with prior art, the utlity model has following beneficial effect:
1, can realize emulation to the computer main board interface circuit; Simultaneously can also the running state information of each main components and parts be exported to external unit; The chip-scale fault detect and the guide maintenance of circuit board be can realize rapidly and accurately, thereby the teaching and the exercise of chip-scale maintenance made things convenient for;
2, circuit structure is simple; Only have the artificial circuit similar, input interface circuit and power module with the interface circuit of computer main board; Saved other functional module on the computer main board, guaranteed greatly to save cost under the prerequisite that teaching and exercise need.
Description of drawings
Fig. 1 is the building-block of logic of the utility model;
Fig. 2 is an embodiment of the utility model.
In conjunction with the accompanying drawing following Reference numeral of mark above that:
The external line interface of 1-, the external line interface of 2-, 3-electromotion pilot lamp, the 4-pilot lamp of starting shooting, 5-functional switch button, 6-direct current input interface.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of embodiment.
A kind of desktop computer computer interface Circuit Emulation Service plate; As depicted in figs. 1 and 2; Comprise the interface circuit emulation module, detect interface module and power module; And adopt double-deck pcb board as circuit substrate, wherein: the interface circuit emulation module is simulated the function of desk-top dynamo-electric brain mainboard interface circuit, the interface circuit part on its circuit structure analogue computer mainboard; Action that can emulation computer main board interface circuit after energising comprises an electromotion pilot lamp 3, a start pilot lamp 4 and a functional switch button 5 on it; Detect interface module and comprise two external line interfaces 1 and 2 of communicating by letter and being connected with the interface circuit emulation module; Gather the running state information of the components and parts to be detected in the said interface circuit emulation module and outwards output; Can also receive simultaneously the command signal and the drive signal of external unit (for example special-purpose Intelligent Measurement card) and send the main components and parts in the said interface circuit emulation module to, so just can satisfy the requirement of chip-scale maintenance; Power module receives outside electric energy and power supply is given the interface circuit emulation module and detected interface module.
Particularly, two external line interfaces 1 among Fig. 2 and 2 are to carry out work through components and parts that each is to be detected and the check point on the chip with the corresponding ways of connecting of stitch in the interface, in this example this two be the specification of 40PIN.Direct current input interface 6 corresponding aforementioned power source modules are used to receive outside direct current, 9VDC for example, and supply power.Electromotion pilot lamp 3 lights when 6 energisings of direct current input interface, and expression is equivalent to computer main board plug-in at this moment.After the energising functional switch button 5 is pressed; The interface circuit emulation module will bring into operation; The pilot lamp 4 of starting shooting this moment lights; The operation of computer main board interface circuit behind the normal boot-strap is being simulated in expression, and the serial interface among Fig. 2, USB interface, keyboard and mouse interface and parallel port interface all produce emulation output, and South Bridge chip and/or I/O chip are then simulated actual mainboard interface circuit above-mentioned interface section is controlled and driven.Click functional switch button 5 again, then can simulate shutdown, the interface circuit emulation module is out of service, and start pilot lamp 4 extinguishes.The main components and parts of during operation each are linked to each other with external line interface 1,2 by check point on it, so can utilize special-purpose equipment such as test card to detect, control, satisfy the needs of chip-scale maintenance and relevant teaching.
More than the disclosed more excellent specific embodiment that is merely the utility model; Especially 40PIN that is mentioned in this example and 9VDC only are the needs in order to explain; Do not represent restriction to the utility model technical scheme; The utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
