Detailed description of the invention
Fig. 1 is the block diagram of the current detecting system according to one embodiment of the invention.Refer to Fig. 1, testing current system
System includes power control 110 and the server 120 as tested board.For asking convenient explanation, at the present embodiment
In only show server 120, in other embodiments, power control 110 also can simultaneously and multiple servers
Connect, to supply power to multiple servers simultaneously.
Power control 110 includes control unit 111, for electrical connecting unit 112, transmission unit 113 and storage
Unit 114.Here, control unit 111 is coupled to for electrical connecting unit 112, transmission unit 113 and storage element
114。
Above-mentioned for electrical connecting unit 112 for example, alternating current output port, it is coupled to server 120, uses power supply
To server 120.And the most wired or wireless server 120 that is coupled to of transmission unit 113 so that server 120
Can link up with power control 110.Wherein, transmission unit 113 is corresponding with for electrical connecting unit 112
Ground configuration.Such as, one supplies electrical connecting unit 112 correspondence to a transmission unit 113.In other embodiments,
Power control 110 also can arrange many groups for electrical connecting unit 112 and transmission unit 113, use supply power to multiple
Server, and link up with multiple servers.
When power control 110 receives a power-off signal by transmission unit 113 from server 120, control
Unit 111 can start to perform testing current program, such as, determines a test point, and server 120 is through test point
Time sends power-off signal to power control 110, and power control 110 receives power-off signal, and breaks
Open the power supply for electrical connecting unit 112, use and stop power supply to server 120.
The storage element 114 of power control 110 can store in advance initial power-off time, terminate power-off time,
Successively decrease power-off time and be powered down to re-power interval time.Wherein, initial power-off time is more than end power-off time,
And initial power-off time is as initial set test point.Power control 110 is provided with initial power-off time,
Terminate power-off time, and the power-off time that successively decreases is set so that the test point of testing current program can be by initially breaking
The electricity time is decremented to terminate power-off time；And arrange and be powered down to re-power interval time, re-power cycle-index
Etc..It is above-mentioned that to be powered down to re-power interval time be then to represent when stopping power supply to server 120 through above-mentioned disconnected
Electricity, to after re-powering interval time, supplies power to the time of server 120 again.
Under i.e. arrange in pairs or groups above-mentioned current detecting system so that each step of testing current program to be described.
Fig. 2 is the flow chart of the current test method of the server according to one embodiment of the invention.Referring to Fig. 1
And Fig. 2, in step s 201, make server 120 power on by power supply control device 110.Here, it is initially set
Test point be initial power-off time.For example, it is assumed that initial power-off time is 2000 milliseconds (millisecond, ms),
Then turn on the power the test point controlling device 110 and make server 120 power on when starting to perform current test method to be
2000ms。
Then, in step S205, server 120 sends power-off signal to power supply control in the time through test point
Device 110.For example, one section of executable program can be write and be placed on the disc operating system (Disk of server 120
Operating System, DOS) under, this executable program is performed when server 120 enters disc operating system,
By above-mentioned executable program through initial power-off time (that is, the time of test point) to power control 110
Go out a power-off signal.
Further, since test point is arranged in power control 110, power control 110 such as can make clothes
After business device 120 powers on, utilize transmission unit 113 that test point each time is sent to server 120.
Then, in step S210, power control 110, when receiving power-off signal, is stopped power supply to service
Device 120.That is, after control unit 111 receives power-off signal, can control to stop power supply for electrical connecting unit 112
To server 120.
Afterwards, in step S215, power control 110 judges whether server 120 shuts down.Power supply controls dress
Put 110 to be powered down to re-power in interval time set, it is judged that whether server 120 shuts down.This be because of
Power-off can be triggered for power control 100 immediately receiving power-off signal, but server 120 is likely because electricity
The reasons such as stream loss are without power-off immediately.If server 120 is re-powering interval time through above-mentioned being powered down to
Within shut down, perform step S220, if server 120 through above-mentioned be powered down to re-power interval time after
Shut down not yet, perform step S225.
In step S220, if be powered down to re-power server interval time 120 shut down above-mentioned, represent this
One test point is not power-off critical point, then power control 110 deducts, with current test point, the power-off time that successively decreases
Value and reset test point, and with the test point that resets to re-execute above-mentioned steps S201 ~ S215, directly
It is less than to test point terminating power-off time.
Represent that server 120 is sending after 2000ms for example, it is assumed that initial power-off time is 2000ms(
Power-off signal), terminate power-off time be 10ms(represent server 120 after 10ms send power-off signal)
And the power-off time that successively decreases is 150ms.Accordingly, the initial test point set is then 2000ms, opens a power supply control
Device 110 processed makes a server 120 power on, and this server 120 is sending a power-off signal extremely after 2000ms
One power control 110, control unit 111, when receiving power-off signal, controls to stop for electrical connecting unit 112
Only supply power to server 120.If being powered down to re-power in interval time, server 120 shuts down, then will
Test point 2000ms deducts 150ms(and successively decreases power-off time), resetting test point is 1850ms, and with weight
Test point (1850ms) after new settings re-executes step S201, by that analogy.When successively decreasing 14 times, i.e. test
It is 10ms that point is decremented to-100ms(less than terminating power-off time) time, just stop performing current test method.
On the other hand, in step S225, if server 120 is after being powered down to re-power interval time
Shutting down not yet, power control 110 supplies power to server 120 again, and re-executes with current test point
Above-mentioned steps S201 ~ S215.Such as, if test point is 2000ms, control unit 111 is receiving server
120 power-off signals sent after 2000ms, stop power supply to server 120, if server 120
Shut down not yet, then re-execute step S201 with test point for 2000ms.
It addition, control unit 111 is also with a counts to control the number of times that the circulation of same test point performs.
Such as, when server 120 does not shuts down (i.e. step S225), control unit 111 can first add up a counts,
Judge that whether counts is less than or equal to re-powering cycle-index (being such as set as 5 times) afterwards.If counting
Number is less than or equal to re-powering cycle-index, and control unit 111 still re-executes above-mentioned steps with current test point
S201 ~ step S215.If counts is more than re-powering cycle-index, control unit 111 is just with current survey
Pilot is as the power-off critical point of server 120, and terminates current test method.
It addition, power control 110 may further provide one arranges interface.Wherein, interface is set and includes multiple
Test point rule, each test point rule have different initial power-off time, terminate power-off time and successively decrease power-off time
Between.Fig. 3 is the schematic diagram arranging interface according to one embodiment of the invention.For convenience of description, the most only
Enumerate three groups of test point rules, so, the most also can increase and decrease test point rule according to testing requirement.
Referring to Fig. 2 and Fig. 3, interface 300 is set and is divided into the page 310 and the test parameter of test point rule
The page 320.Include that three groups of test point rules and re-power cycle-index, each group of survey at the page 310
Initial power-off time in pilot rule, terminate power-off time and the parameter field of three kinds of parameters of power-off time of successively decreasing
311-1 ~ 311-3,312-1 ~ 312-3,313-1 ~ 313-3 all can be by user's sets itself.Separately, user also can be certainly
Row arranges the parameter field 314 re-powering cycle-index, i.e. each test point needs the number of times of retest, with
And sets itself is powered down to re-power the parameter field 321 of interval time.In this, it is assumed that parameter field 314 sets
Being 5, parameter field 321 is set as 80ms.Separately, three groups of test point rules are assumed as follows.
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 by 2000ms, often
The secondary 200ms of successively decreasing is until being 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 by 1000ms, and the 100ms that every time successively decreases is until being decremented to 100ms.3rd
Group test point rule is 100ms(parameter field 311-3) to 10ms(parameter field 312-3), its successively decrease power-off time
Between be 10ms(parameter field 313-3).That is, initial power-off time is by 100ms, and the 10ms that every time successively decreases is straight
To being decremented to 10ms.
Here, as a example by using 2000ms as initial test point, server 120 send after 2000ms disconnected
The signal of telecommunication is to power control 110.When power control 110 receives power-off signal, in the page 320
The parameter field 322 of counts is then automatically filled in 1.If through being powered down to re-power 80ms interval time
Afterwards, server 120 shuts down not yet, the most again supplies power to server 120, and again holds with test point 2000ms
Row testing current program.If the counts added up has added up to be 6, now, counts is more than re-powering
Cycle-index, represents that test point 2000ms had been tested 5 times, accordingly, critical with test point 2000ms for power-off
Point, and terminate testing current program.
Accordingly, the available interface 300 that arranges of user comes sets itself test point rule, i.e. initial power-off time, knot
Bundle power-off time and the power-off time that successively decreases, and also can be powered down to re-power interval time and again by sets itself
Power-up cycle number of times.
It addition, in other embodiments, power control 110 also can couple, also with a station server 120 incessantly
Can couple with multiple servers.Under it is described as another example.

Server 120 utilizes power supply to receive unit 403 and couple for electrical connecting unit 112-1, utilize transmission unit 404 and
Transmission unit 113-1 links up.
Storing executable program in storage element 402, thereby the processing unit 401 of server 120 is by holding
Line program is often being separated by an interval time (that is, the time of test point) and is sending power-off signal, and by transmission unit 404
Power-off signal is sent to power supply device 110.Here, current test method and step S201 ~ step S225 phase
With, by this current test method, re-power cycle-index (such as: 5 times) when passing through in same test point
Afterwards, server 120 does not still shut down, then with this test point for power-off critical point, and terminate testing current program.
