Description
[technical field]
The utility model relates to a kind of computer motherboard proving installation, particularly a kind of computer main-board on-off fatigability test board.
[background technology]
Along with popularizing of computing machine, many producers begin a large amount of schedulers to satisfy the demands of consumers, and in the process of scheduler, often need to do different tests.The mainboard of computing machine is the basic place of computing machine, and therefore the test to mainboard is the necessary work of the production of each computation machine, manufacturing, research manufacturer.Carry out automatic test for the product of mass and can improve work and production efficiency.DC electronic load technology of the prior art does not possess the fatigability test of realization to PC (computing machine) mainboard implementation automatic switching, only can realize the test to peripheral power module.Therefore, design a kind of fatigability proving installation that can carry out automatic switching to the PC mainboard, become the problem of primary solution.
[summary of the invention]
Technical problem to be solved in the utility model is to provide a kind of fatigability test board that can carry out automatic switching to the PC mainboard.
The utility model is by the following technical solutions:
The automatic test board of computer motherboard comprises a main control chip, a display unit, a push-button unit, a capacitive load test interface, a resistive load test interface, a PC host switch control interface, wherein the main control chip is connected with display unit, push-button unit, capacitive load test interface, resistive load test interface, PC host switch control interface respectively.
Described main control chip is the AT89S51 single-chip microcomputer.
Described display unit is 7 sections 4 charactrons.
The utility model has added the Based Intelligent Control to the PC main-board on-off, has solved the uncontrollable PC mainboard of former DC electronic load technology and has regularly started the bottleneck of closing, and has realized the PC mainboard is carried out the fatigability test of automatic switching.
[description of drawings]
In conjunction with the embodiments the utility model being done one with reference to the accompanying drawings describes in detail.
Fig. 1 is the system architecture diagram of the utility model hardware.
Fig. 2 is the utility model software execution flow journey figure.
[embodiment]
The automatic test board of computer motherboard, see also Fig. 1, comprise a main control chip, a display unit, a push-button unit, a capacitive load test interface, a resistive load test interface, a PC (computing machine) host switch control interface, wherein the main control chip is connected with display unit, push-button unit, capacitive load test interface, resistive load test interface, PC host switch control interface respectively.This automatic test board adopts the AT89S51 single-chip microcomputer as the main control chip, adopts the display mode of 7 sections 4 charactrons, and collocation high-performance N-MOS (N channel field-effect pipe) pipe is formed the switch loop.
Push-button unit is made up of 5 kinds of function keys, finishes the control to each function.Fig. 1 right part is DC electronic load testing functional areas, needs external power module to be measured, self-configuring appearance, resistive load during use.Fig. 1 left part is PC mainboard upper electrical switch machine functional areas, can select mainboard DC (direct current) 12V voltage input control mode, promptly imports or does not import with certain frequency, controls the switching on and shutting down of PC mainboard; Also can select mainboard POWER BOTTON (power key) by key control.

2---:AC (interchange) control model
The 3---:DC automatic control mode
4---: automatic switching pattern
5---: power supply control model
2. operation steps
1) DC control model
Single-chip microcomputer powers on
By " SET " selection " 1---"
Enter pattern by " ENTER "
By "+" or "-" selector switch frequency
By " ENTER " program run
2) AC control model
Single-chip microcomputer powers on
By " SET " selection " 2---"
Enter pattern by " ENTER "
By "+" or "-" selector switch frequency
By " ENTER " key
Program run
3) DC automatic control mode
Single-chip microcomputer powers on
By " SET " selection " 3---"
By " ENTER "
Program run
(automatic mode only carries out DC control, with different switching frequencies the load automatic switch is circulated.)
4) automatic switching pattern
Single-chip microcomputer powers on
By " SET " selection " 4---"
By " ENTER "
Program run
(carrying out switching on and shutting down) with cycle 40S
5) power supply control model
Single-chip microcomputer powers on
By " SET " selection " 5---"
By " ENTER "
Program run
(DC-12V IN being carried out switch control) with cycle 40S
The utility model not only possesses the transient response of test DC load, regulates output capacitance, and the function of output resistance also possesses the function to PC mainboard intelligent switch machine.Solved originally and can only increase substantially testing efficiency by manually carrying out the bottleneck of switching on and shutting down.
