Other features of the present invention and effect, will clearly be presented in the embodiment with reference to schema, wherein：
Fig. 1 is a schematic diagram, illustrates an embodiment of servo-drive system of the present invention；
Fig. 2 is a system block diagrams, in illustrating the servo-drive system, a random start device of each server unit；And
Fig. 3 is a sequential chart, illustrates the relation of one first logical signal, one second logical signal and a trigger of the random start device.
【Specific embodiment】
Refering to Fig. 1 and Fig. 2, an embodiment of servo-drive system of the present invention, a power supply unit 100 is electrically connected, the power supply unit 100 produces a stand-by electric（standby power）And an electric power, and the servo-drive system includes multiple server units 2.
Each server unit 2 receives the stand-by electric and the electric power, and has a random start device（Random turn-on device）1, and the random start device 1 includes a baseboard management controller（Baseboard Management
Controller）11st, a trigger generator 12, and a control chip group 13.
The baseboard management controller 11 be used in itself initialization loading procedure 111 start loading start data when, to back-end hardware（Such as control chip group 13）Random triggering start, then proceedes to perform itself other initialization operation in advance, and its random triggering implements technology and is：The baseboard management controller 11 stores a scheduled time, and receives the stand-by electric to maintain running, and continues via wherein two universal input output connecting pins（General Purpose
Input/Ouput pin, GPIO pin）One first logical signal, and one second logical signal are exported, first and second logical signal is to be set in one first level（Such as logic 1）And one second level（Such as logical zero）One of both.First logical signal is initially to be set in first level, second logical signal is initially to be set in second level, when through a random time, the baseboard management controller 11 sets first logical signal to second level, and when the scheduled time is added through the random time, the baseboard management controller 11 sets second logical signal to first level.In detail, the baseboard management controller 11 includes the initialization loading procedure of data when system initialization needed for loading start（Boot loader, or uboot）111st, one produce one be relevant to in-cycle work random value random number generator 112, store the random value buffer 113, according to the random value as count a random time total amount to carry out the first timer 114 of timing, and one according to the random time plus the scheduled time as the total amount for counting to carry out the second timer 115 of timing, and the first timer 114 and second timer 115 are synchronous countdowning.
The trigger generator 12 electrically connects the baseboard management controller 11 to receive first and second logical signal, and produces the trigger that a pulse width is equal to the scheduled time.Specifically, the trigger generator 12 includes an OR gate（OR gate）121st, a first resistor 122, and a second resistance 123.The OR gate 121 with one receive first logical signal first end, one receive second logical signal the second end, and one export the trigger output end.The first resistor 122 receives the second end of the electric power from the power supply unit 100 with a first end for electrically connecting the OR gate 121 and one, and first logical signal is initially set in first level.Second logical signal is initially set in second level by first end of the second resistance 123 with second end for electrically connecting the OR gate 121 and the second end of a ground connection.
The control chip group 13 electrically connects the output end of the OR gate 121 of the trigger generator 12, and when the trigger is received, performs an in-cycle work, and in the present embodiment, the control chip group 13 is with platform controller hub（Platform Controller Hub, PCH）To implement.
Coordinate refering to Fig. 3, the first above-mentioned level is logic 1, and second level is logical zero, at the power-on time t=0 second, the first logical signal of the baseboard management controller 11 is initially set in logic 1, and the second logical signal is initially set in logical zero.
Then, the random number generator 112 of the baseboard management controller 11 randomly generates the random value, such as 15, and the random value is stored to the buffer, the baseboard management controller 112 sets the first timer 114 and starts one random time of timing i.e. according to the random value, i.e. 15 seconds, and it is synchronous according to the stored scheduled time, set the second timer 115 and start the timing random time plus the scheduled time, such as 16 seconds（The wherein scheduled time is 1 second）.
Then, when 114 timing of the first timer random time（The t=15 seconds）At the end of, first logical signal can be triggered logical zero is converted into from logic 1；And work as through 115 timing of the second timer random time plus the scheduled time（The t=16 seconds）At the end of, second logical signal can be triggered logic 1 is converted into from logical zero.Now, the OR gate 121 changes according to the logic of first and second logical signal and produces a low logic pulse（low pulse）As the trigger triggering the control chip group 13.What here was supplemented is, although the present embodiment with the first level be logic 1, the second level as logical zero as a example by illustrate, but both also can implement on the contrary, and to produce the trigger be the high logical pulse positioned at logic 1, and are not limited with the person.
Especially, the random value all identical probability according to 11 generating random numbers of baseboard management controller of the random start device 1 of each server unit 2 are very low, that is, according to the corresponding random value, the corresponding random time all identical probability of timing are also very low respectively respectively for each server unit 2, therefore this case invention can reduce server unit 2 while performing the probability of described in-cycle work, thus reduce causing the chance of the overload of power supply unit 100.
In addition, as each server unit 2 is when the baseboard management controller 11 is initialized, by the baseboard management controller 11, and coordinate the trigger generator 12 to export trigger to start the control chip group 13, therefore each server unit 2 of the present invention completes initialization in the initialization loading procedure 111 of the baseboard management controller 11（At least 45 seconds）Before, can just perform in-cycle work, without etc. it is to be initiated complete, just for example pass through layout power-up sequence function, the next server unit 2 of triggering is started shooting, or passes through the remotely controlled start of remote connection function, therefore can save wait initialization time；And, according to the random time, each server unit 2 also can be started shooting 2 seconds, 3 seconds ... above minimum for 1 second, that is, can be in Each point in time（1 second to any random time）, low logic pulse is produced, in-cycle work is performed.
Also, the initialization loading procedure 111 of the baseboard management controller 11 is only absorbed in loading start data, the such as kernel of (SuSE) Linux OS in initialization time（kernel）, and the in-cycle work is entirely by the first timer 114, the random value that the second timer 115 is provided according to the random number generator 112, to be countdowned, both are arrived when the total amount one of corresponding timing time, the automatic transition of first and second logical signal exported by two universal input output connecting pins is successively triggered, and coordinate the OR gate 121 to reach the in-cycle work, so the hardware that the now action of the first timer 114 and the second timer 115 is entirely the baseboard management controller 11 is automatically controlled, and the program loading of unrelated initialization loading procedure 111.
In sum, the present invention staggers the available machine time of the server unit 2 of servo-drive system, and does not cause power supply unit 100 to transship, and each server unit 2 can perform in-cycle work in random time, therefore can reach really the purpose of the present invention.
Only as described above, only presently preferred embodiments of the present invention, when the scope of of the invention enforcements can not be limited with this, i.e., the simple equivalence changes made according to claims of the present invention and patent specification content generally with modify, all still remain within the scope of the patent.
