Abstract
The utility model discloses a test card for a computer motherboard based on an LPC (Linear Power Controller) bus. The test card comprises an integrated block, a decoding chip and an LED (Light Emitting Diode) display module, wherein the decoding chip and the LED display module are fixed in a slot of the integrated block; and a bus head terminal is embedded into an input head of the integrated block. The test card for the computer motherboard based on the LPC bus, which is provided by the utility model, is simple in structure, easy in assembly, low in cost and fewer in required parts; in addition, no great space of the motherboard is occupied; meanwhile, the test card is small in size and easy to carry and can be used as a device for testing the motherboards with various specifications.
Description
Technical field
The utility model relates to the computer performance field tests, specifically is exactly a kind of computer motherboard test card based on lpc bus.
Background technology
Traditionally; Motherboard in use utilizes test card whether the operating state of computer and the input-output system on the motherboard are in normal condition usually and detects; Wherein for the operating state of computer whether be in method that normal condition adopts be the self-control testing tool or take corresponding machine shell panel and motherboard mutually lotus root fetch detection, whether being in the mode that normal condition uses always for the input-output system on the motherboard is directly the data of input/output system burning to be carried out dependence test in the concatenation type peripheral interface ROM (read-only memory) of motherboard.In PC motherboard exploitation or later maintenance process, the slip-stick artist often need come to analyze fast and effectively and deal with problems by the Debug card, so the debug lesser calorie of the numerous and confused exploitation of each PC manufacturer oneself or plate carry functional module and satisfy the demand of self; The Debug card product that has occurred various general-purpose interfaces on the present market, like PCI, the Debug card at ISA interface; But often physical dimension more greatly, along with product is more and more microminiaturized, common PCI; The ISA draw-in groove removes from mainboard; And plate carries module and also takies on the mainboard shortcomings such as wiring area and cost waste, and costs an arm and a leg, and interchangeability is not high.
The utility model content
The utility model technical matters to be solved provides a kind of computer motherboard test card based on lpc bus.It is simple in structure, and it is little to take the mainboard area, with low cost, not only is easy to carry about with one, and can tests the motherboard of existing plurality of specifications, and versatility has adapted to the fast development of computer industry more by force.
Technical scheme
A kind of computer motherboard test card based on lpc bus; Integrated package, Akom AK2001 type decoding chip, LED that it includes 1.4～1.6mm show module; Decoding chip and LED show that module is fixed in the draw-in groove of integrated package; The input head of integrated package is inlaid with female head end; Motherboard is installed in the test support, and female head end is connected on the corresponding motherboard Du Pont terminal interface and obtains the Host Status signal, is delivered to decoding chip through the circuit on the circuit board; But signal converts display message to through demoder in decoding chip, and the LED driver module in the decoding chip drives displayable signal and shows module displays through the circuit on the integrated package at LED.
Beneficial effect
A kind of computer motherboard test card based on lpc bus that the utility model provided is simple in structure; The parts that need seldom are easy to assembling, and are with low cost; And need not take too large space of mainboard; Outward appearance is small and exquisite simultaneously, is easy to carry about with one, and can be used as the device that various different size host board testings are used.
Description of drawings
Accompanying drawing 1 is the said computer motherboard test card of a utility model structural representation.
Accompanying drawing 2 is the said computer motherboard test card of a utility model operating circuit synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to set forth.
A kind of computer motherboard test card that the utility model designed based on lpc bus; It includes integrated package 1, employing Akom AK2001 type decoding chip 2, the Dual 7-segment type LED that thickness is 1.4～1.6mm and shows module 3; Decoding chip 2 shows that with LED module 3 is fixed in the draw-in groove of integrated package 1; It is 5x2mm that the input head of integrated package 1 is inlaid with specification, is spaced apart female head end 4 of 2mm.
Motherboard is installed in the test support; Female head end 4 is connected on the corresponding motherboard Du Pont terminal interface and obtains the Host Status signal; Be delivered to decoding chip 2 through the circuit on the circuit board 1; But signal converts display message to through demoder 2a in decoding chip 2, but the LED driver module 2b in the decoding chip 2 shows that through the circuit driving LED on the integrated package 1 module 3 shows the display message that converts to through demoder 2a.
Each parts in the utility model are installed together by the said connected mode of the utility model; When needing the Test Host board status motherboard to be measured is placed in the test bench; Female head end 4 of host board testing card is inserted Du Pont's terminal interface corresponding on the motherboard; Decoding chip 2 reads the motherboard status signal; Become LED to show the information that module 3 is readable the Host Status conversion of signals through demoder 2a, LED drives module 2b driving LED and shows that module 3 shows the signal of demoder 2a conversion, has realized the purpose that various motherboard performances are tested.A kind of computer motherboard test card that the utility model provided is simple in structure, and the parts that need seldom are easy to assembling; With low cost, and need not take too large space of mainboard, outward appearance is small and exquisite simultaneously; Be easy to carry about with one, can be used as the device that various different size host board testings are used.
