Embodiment
The present invention can be applied in the automatic switching test system, specifies concrete scheme of the present invention below in conjunction with the drawings and specific embodiments.
Referring to shown in Figure 1, in automatic switching test system, test card for computer 102 of the present invention links to each other with power control box 103 with tested machine 101.This test card can receive the switching on and shutting down control signal of sending from power control box 103, controls switching on and shutting down, warm start of tested machine etc.; And this test card can also detect the test mode of tested machine, the system configuration information of obtaining tested machine and tested machine POST self check information etc. in real time, and these information are sent to main control computer 104 by power control box 103.
Referring to shown in Figure 2, this test card comprises switching on and shutting down control module 201, POST Function detection module 206, communication control module 204, single chip control module 203, PCI chip 208, storage unit 207 and liquid crystal display LCD202.
Switching on and shutting down control module 201 be used to control tested machine system start-up and close, system reset and detect tested dynamo-electric source.
POST Function detection module 206 is to be used for obtaining the tested machine POST self check message code that testing process occurs that powers on.
Communication control module 204 realizes that by 485 serial ports this serial communication can be realized long communication line, also convenient expansion.
Single chip control module 203 is control cores of function card, is used to coordinate functions such as control information transmission and logic control.
PCI chip 208, storage unit 207 and communication control module 204 are realized the information transmission between main control computer and the tested machine together.
Because test card will receive the control signal of sending from main control computer, thereby control tested machine switching on and shutting down, so the power supply of the single chip control module 203 in the test card, communication control module 204 and switching on and shutting down control module 201 is provided by the power control box in the automatic switching test system, as long as power control box one energized, these three modules have just powered on.In addition, behind tested machine electrifying startup, POST Function detection module 206 and PCI chip 208 could be worked, so the power supply of these two modules is provided by tested machine.That is to say that tested machine one starts, these two modules are started working.
Introduce the course of work of test card for computer below in conjunction with accompanying drawing 2.
Pass through 15PIN serial ports 205 to communication control module 204 from the control signal of power control box, communication control module 204 is sent to single chip control module 203 with this control signal, single chip control module 203 is judged this signal type, makes corresponding action according to signal type then.If the control signal of open and close machine or reset command, 203 of single chip control module are delivered to switching on and shutting down control module 201 with this signal, by switching on and shutting down control module 201 control starting switch or reset switch short circuits, tested machine carries out open and close machine or homing action; If the control signal of warm start order, this signal then is sent to tested machine through PCI chip 208, and tested machine then carries out warm start.
And, switching on and shutting down control module 201 1 powers on, this module just begins to detect the state 5VSB of tested machine alternating current 220V power supply and the power-up state 5V of mainboard, and testing result delivered to single chip control module 203, under the control of single chip control module 203, testing result reaches power control box through communication control module 204 and 15PIN serial ports 205.
In addition, tested machine is in case start, POST Function detection module 206 just gets access to tested machine self check information by pci bus 209, and self check information is stored in the storage unit 207, then under the control of one-chip computer module, on the one hand the self check message code is shown on LCD202, by communication control module 204 and 15PIN serial ports 205 self check information is delivered to power control box on the other hand, and it is forwarded to main control computer by power control box.
POST detects and passes through, and tested machine enters operating system.At this moment, tested machine obtains program with log-on message, obtain the system configuration information of tested machine, system configuration information is sent in the PCI chip 208 of test card through pci bus 209 interfaces then, the form of PCI chip 208 conversion configurations information, be sent to single chip control module 203, under the control of single chip control module 203, the system configuration information of tested machine spreads out of to power control box through communication control module 204 and 15PIN serial ports 205, and by power control box it is forwarded to main control computer.
Test card for computer of the present invention adopts the power supply mode of separate type, when the alternating current 220V power supply of tested machine is in power-down state or system and is in closed condition, this card can detect the alternating current 220V of tested machine and the state of system's open and close in real time, and this state is reported to main control computer in real time.
Test card for computer of the present invention is integrated three big function---power on POST detection and fault diagnosis, switching on and shutting down control, information communication transfer functions.During application, this test card directly is inserted on the PCI groove of tested machine and gets final product, and has simplified building of test environment greatly.
