Embodiment
Fig. 1 is the calcspar according to the current detecting system of one embodiment of the invention.Please refer to Fig. 1, current detecting system comprises power control 110 and the server 120 as tested board.For asking convenient explanation, only show in the present embodiment server 120, in other embodiments, power control 110 also can be connected with multiple servers simultaneously, to supply power to multiple servers simultaneously.
Above-mentioned is for example alternating current output port for electrical connecting unit 112, and it is coupled to server 120, uses and supplies power to server 120.And transmission unit 113 is for example the wired or wireless server 120 that is coupled to, server 120 can be linked up with power control 110.Wherein, transmission unit 113 configures accordingly with supplying electrical connecting unit 112.For example, one corresponds to a transmission unit 113 for electrical connecting unit 112.In other embodiments, power control 110 also can arrange many groups for electrical connecting unit 112 and transmission unit 113, uses and supplies power to multiple servers, and link up with multiple servers.
When power control 110 by transmission unit 113 in the time that server 120 receives a power-off signal, control module 111 can start to carry out testing current program, for example, determine a test point, server 120 sends power-off signal to power control 110 through the time of test point, and power control 110 receives power-off signal, and disconnect the power supply for electrical connecting unit 112, use and stop power supply to server 120.
In the storage element 114 of power control 110, can store in advance initial power-off time, finish power-off time, power-off time and be powered down to and re-power interval time successively decreases.Wherein, initial power-off time is greater than end power-off time, and initial power-off time is as the test point initially setting.In power control 110, be provided with initial power-off time, finish power-off time, and the power-off time that successively decreases is set, make the test point of testing current program to be decremented to end power-off time by initial power-off time; And setting is powered down to and re-powers interval time, re-powers cycle index etc.Above-mentioned be powered down to re-power interval time be representative in the time stopping power supply to server 120 through above-mentioned be powered down to re-power interval time after, again supply power to time of server 120.
Under the above-mentioned current detecting system of arranging in pairs or groups each step of testing current program is described.
Fig. 2 is the process flow diagram according to the current test method of the server of one embodiment of the invention.Referring to Fig. 1 and Fig. 2, in step S201, by power supply control device 110, server 120 is powered on.At this, the test point initially setting is initial power-off time.For example, suppose that initial power-off time is 2000 milliseconds (millisecond, ms), opening power control device 110 and test point that server 120 is powered on while starting to carry out current test method is 2000ms.
Then,, in step S205, server 120 sends power-off signal to power control 110 in the time through test point.For instance, can write disc operating system (DOS) (the DiskOperating System that one section of executable program is placed on server 120, DOS) under, in the time that having entered disc operating system (DOS), carries out server 120 this executable program, sending a power-off signal through initial power-off time (, the time of test point) to power control 110 by above-mentioned executable program.
In addition, because test point is arranged in power control 110, power control 110 for example can, after server 120 is powered on, utilize transmission unit 113 that test point is each time sent to server 120.
Then,, in step S210, power control 110, in the time receiving power-off signal, is stopped power supply to server 120.,, after control module 111 receives power-off signal, can control for electrical connecting unit 112 and stop power supply to server 120.
Afterwards, in step S215, power control 110 judges whether server 120 shuts down.Power control 110 meetings re-power in interval time in being powered down to of setting, and judge whether server 120 shuts down.This is because power control 100 can trigger power-off immediately receiving power-off signal, but server 120 is likely because former thereby not power-off immediately such as current loss.If server 120 through above-mentioned be powered down to re-power within interval time shut down, execution step S220, if server 120 through above-mentioned be powered down to re-power interval time after not yet shutdown, perform step S225.
In step S220, if re-power server 120 in interval time and shut down above-mentioned being powered down to, represent that this test point is not power-off critical point, power control 110 deducts the value of the power-off time that successively decreases and resets test point with current test point, and re-execute above-mentioned steps S201 ~ S215 with the test point resetting, until being less than, test point finishes power-off time.
For example, suppose that initial power-off time is that 2000ms(represents that server 120 is through sending power-off signal after 2000ms), to finish power-off time be that 10ms(represents that server 120 sends power-off signal after passing through 10ms) and the power-off time that successively decreases be 150ms.Accordingly, the test point of initial setting is 2000ms, opening a power control 110 powers on a server 120, this server 120 is sending power-off signal to power control 110 after 2000ms, control module 111, in the time receiving power-off signal, is controlled for electrical connecting unit 112 and is stopped power supply to server 120.If re-power in interval time being powered down to, server 120 has shut down, test point 2000ms is deducted to the 150ms(power-off time that successively decreases), resetting test point is 1850ms, and re-execute step S201 with the test point after resetting (1850ms), by that analogy.When successively decreasing 14 times, be decremented to-100ms(of test point be less than finish power-off time be 10ms) time, just stop carrying out current test method.
On the other hand, in step S225, if server 120 through being powered down to re-power interval time after not yet shut down, power control 110 supplies power to server 120 again, and re-executes above-mentioned steps S201 ~ S215 with current test point.For example, if test point is 2000ms, control module 111 receive server 120 through after 2000ms, send power-off signal time, stop power supply to server 120, if server 120 shuts down not yet, re-execute step S201 take test point as 2000ms.
In addition, control module 111 also can utilize a counts to control the number of times that same test point circulation is carried out.For example, server 120 do not shut down in (being step S225), control module 111 counts that can first add up, judges whether counts is less than or equal to re-power cycle index (being for example set as 5 times) afterwards.Re-power cycle index if counts is less than or equal to, control module 111 still re-executes above-mentioned steps S201 ~ step S215 with current test point.If being greater than, counts re-powers cycle index, just the power-off critical point of control module 111 using current test point as server 120, and finish current test method.
In addition, power control 110 also can further provide one interface is set.Wherein, interface is set and comprises multiple test point rules, each test point rule has different initial power-off times, finishes power-off time and the power-off time that successively decreases.Fig. 3 is the schematic diagram that interface is set according to one embodiment of the invention.For convenience of description, only enumerate in the present embodiment three groups of test point rules, so, also can increase and decrease test point rule according to testing requirement in other embodiments.
Referring to Fig. 2 and Fig. 3, interface 300 is set and is divided into the page 310 of test point rule and the page 320 of test parameter.Comprise that at the page 310 three groups of test points rule and re-powers cycle index, initial power-off time in each group test point rule, finish power-off time and parameter field 311-1 ~ 311-3,312-1 ~ 312-3, the 313-1 ~ 313-3 of the three kinds of parameters of power-off time of successively decreasing all can be set voluntarily by user.Separately, user also can arrange the parameter field 314 that re-powers cycle index voluntarily, that is, each test point needs the number of times of repeated test, and sets and be powered down to the parameter field 321 that re-powers interval time voluntarily.At this, suppose that parameter field 314 is set as 5, parameter field 321 is set as 80ms.Separately, three groups of following institutes of test point rule are supposed.
First group of test point rule is 2000ms(parameter field 311-1) to 1000ms(parameter field 312-1), its power-off time that successively decreases is 200ms(parameter field 313-1).That is, initial power-off time is started by 2000ms, and the 200ms that at every turn successively decreases is until be decremented to 1000ms.Second group of test point rule is 1000ms(parameter field 311-2) to 100ms(parameter field 312-2), its power-off time that successively decreases is 100ms(parameter field 313-2).That is, initial power-off time is started by 1000ms, and the 100ms that at every turn successively decreases is until be decremented to 100ms.The 3rd group of test point rule is 100ms(parameter field 311-3) to 10ms(parameter field 312-3), its power-off time that successively decreases is 10ms(parameter field 313-3).That is, initial power-off time is started by 100ms, and the 10ms that at every turn successively decreases is until be decremented to 10ms.
At this, take 2000ms, as initial test point as example, server 120 is sending power-off signal to power control 110 after 2000ms.In the time that power control 110 receives power-off signal, 322 of the parameter fields of the counts in the page 320 insert 1 automatically.If through after being powered down to and re-powering 80ms interval time, server 120 shuts down not yet, again supplies power to server 120, and re-executes testing current program with test point 2000ms.If the counts being added up is totally 6, now, counts is greater than and re-powers cycle index, represents that test point 2000ms had tested 5 times, accordingly, take test point 2000ms as power-off critical point, and finishes testing current program.
Accordingly, user can utilize and interface 300 is set sets voluntarily test point rule, initial power-off time, finish power-off time and the power-off time that successively decreases, and can set to be voluntarily powered down to and re-power interval time and re-power cycle index.
In addition, in other embodiments, power control 110 also can couple with a station server 120 incessantly, also can couple with multiple servers.Under lift again an example explanation.
Fig. 4 is the calcspar according to the current detecting system of another embodiment of the present invention.Please refer to Fig. 4, current detecting system comprises power control 110 and server 120 ~ 140 as tested board etc.Wherein, each station server all correspondence be coupled to one group for electrical connecting unit and transmission unit.; server 120 correspondences are coupled to for electrical connecting unit 112-1 and transmission unit 113-1; server 130 correspondences are coupled to for electrical connecting unit 112-2 and transmission unit 113-2, and server 140 correspondences are coupled to for electrical connecting unit 112-3 and transmission unit 113-3 etc.At this, identical with the function for electrical connecting unit 112 and transmission unit 113 of Fig. 1 respectively with transmission unit 113-1 ~ 113-3 for electrical connecting unit 112-1 ~ 112-3, do not repeat them here.
In the present embodiment, take the member of server 120 prescribed server 120 as example.And server 130 is also similar to server 120 to the member of server 140 or other servers that do not illustrate, do not carry therefore omit.
In storage element 402, store executable program, (the processing unit 401 of server 120 is often being separated by an interval time by executable program by this, the time of test point) send power-off signal, and by transmission unit 404, power-off signal is sent to power supply device 110.At this, current test method is identical with step S201 ~ step S225, by this current test method, for example, when after same test point process re-powers cycle index (: 5 times), server 120 is not shutdown still, take this test point as power-off critical point, and finish testing current program.
In sum, in the above-described embodiments, by transmitting power-off signal to power control by server, thereby can ignore power control completely and need to how long enter disc operating system (DOS) for server, simplify testing process, save the test duration.In addition,, in the normal situation of test, in the time that server arrives power-off critical point, power control will rest on this test point, and can not carry out the test of next test point.Again, also can in power control, set different test point spacing (power-off time successively decreases) according to different test point scope (being that initial power-off time is to the scope that finishes power-off time), increase substantially the convenience in test.In addition, by transmitting power-off signal to power control by server, in the time that server goes wrong, for example direct current cannot power on, server is opened selftest (Power On Self Test at electric power, POST) in process, pawn, or cannot enter disc operating system (DOS) etc., server just cannot transmit power-off signal to power control, make the state of test process in suspending, accordingly, tester can learn that server goes wrong like a cork, thereby save the process that extension serial port (serial port) or query note shelves etc. search problem a little, significantly save the test duration.
Although the present invention discloses as above with embodiment; so it is not in order to limit the present invention; under any, in technical field, have and conventionally know the knowledgeable; without departing from the spirit and scope of the present invention; when doing a little change and retouching, therefore protection scope of the present invention is when being as the criterion of defining depending on accompanying claim.
