Fig. 2 illustrates and is the circuit framework figure according to the servo-drive system of another embodiment of the present invention.
Embodiment
Fig. 1 illustrates and is the circuit framework figure according to the servo-drive system of one embodiment of the invention.Please with reference to Fig. 1, servo-drive system 100 comprises baseboard management controller 110, latch cicuit 120, connector 131 and 132, substrate 141 and 142 and luminescence component 161～164.Wherein, baseboard management controller 110 is configured on the substrate 141 with connector 131, and connector 132, latch cicuit 120 and luminescence component 161～164 then are configured on the substrate 142.
Please continue with reference to Fig. 1, connector 131 is coupled to baseboard management controller 110.Connector 132 is coupled to latch cicuit 120.Latch cicuit 120 is coupled to first end of luminescence component 161～164, and second end of luminescence component 161～164 then is a ground connection.Connector 132 more is coupled to connector 131 via transmission line 150.In addition, in the present embodiment, substrate 141 and 142 for example is a printed circuit board (PCB).Luminescence component 161～164 is made up of a light emitting diode respectively.
In whole start, baseboard management controller 110 is in order to produce serial data DS
1And a plurality of control signals.In the present embodiment, these control signals comprise clock signal CLK
1, load signal LD
1, enable signal EN
1And reset signal RST
1On the other hand, be coupled to connector 132 because connector 131 sees through transmission line 150, so latch cicuit 120 can receive the serial data DS from baseboard management controller 110
1With these control signals.
Afterwards, latch cicuit 120 can cooperate these control signals to come serial data DS
1Carry out the data-switching of transformation from serial to parallel, and produce a plurality of shows signal S according to this
11～S
14For example, in the present embodiment, latch cicuit 120 can be according to reset signal RST
1Elder generation's replacement interior data.Afterwards, latch cicuit 120 can be according to clock signal CLK
1Come serial data DS
1Carry out the operation of displacement, and according to load signal LD
1Come operation that the serial data after the displacement is latched.By this, serial data DS
1Can be converted into a plurality of shows signal S
11～S
14, and be latched in the latch cicuit 120 with parallel form.
On the other hand, receive enable signal EN when latch cicuit 120
1The time, the shows signal S in the latch cicuit 120
11～S
14To be exported to luminescence component 161～164 respectively.By this, luminescence component 161～164 can be according to the shows signal S that is received
11～S
14And send corresponding light source.For instance, when the interior arrangement of servo-drive system takes place when unusual, baseboard management controller 110 can the corresponding shows signal S of output
11～S
14By this, the light source that luminescence component 161～164 is sent will produce color or bright dark variation, and then lets the user change according to these light sources to find out unusual interior arrangement.
In the present embodiment, because servo-drive system 100 uses latch cicuit 120 to carry out the data-switching of transformation from serial to parallel, so can transmit data with the mode of serial between connector 131 and 132.Thus, even the interior arrangement of servo-drive system 100 increases, just be configured in luminescence component on the substrate 142 when increasing, connector 131 and 132 volume can't increase along with the increase of shows signal.In other words, present embodiment can make servo-drive system utilization spatially have more elasticity, and can reduce the manufacturing cost of servo-drive system.
In addition, even the number of the luminescence component on the substrate 142 increases, baseboard management controller 110 also only need utilize a universal input and output port to export serial data DS
1Thus, baseboard management controller 110 just has the more universal input and output port of multiresidue, sends out in order to carrying out the control signal of other function, and then causes the periphery control of servo-drive system 100 more complete.
Fig. 2 illustrates and is the circuit framework figure according to the servo-drive system of another embodiment of the present invention.Please with reference to Fig. 2, servo-drive system 200 comprises baseboard management controller 210, latch cicuit 221 and 222, connector 231 and 232, substrate 241 and 242 and luminescence component 261～268.Wherein, baseboard management controller 210 is configured on the substrate 241 with connector 231, and latch cicuit 221 and 222, connector 232 and luminescence component 261～268 are configured on the substrate 242.

In whole start, baseboard management controller 210, connector 231 and 232 and the principle of work of transmission line 250, similar with baseboard management controller 110, connector 131 among Fig. 1 embodiment with 132 and transmission line 150.At this, the serial data DS that baseboard management controller 210 can be exported
2And a plurality of control signals.In the present embodiment, these control signals comprise clock signal CLK
2, load signal LD
2, enable signal EN
2And reset signal RST
2Latch cicuit 221 can cooperate these control signals to come serial data DS
2Carry out the data-switching of transformation from serial to parallel, and produce shows signal S according to this
21～S
24By this, luminescence component 261～264 will receive shows signal S
21～S
24And send corresponding light source according to this.
Yet, be that with the maximum difference of Fig. 1 embodiment latch cicuit 221 is also with serial data DS
2Postpone after one period schedule time and produce serial data NDS according to this.In addition, latch cicuit 222 is identical with the operation mechanism of latch cicuit 221.Therefore, latch cicuit 222 can receive serial data NDS, and be used to from baseboard management controller 210 control signal (for example: clock signal CLK
2, load signal LD
2, enable signal EN
2And reset signal RST
2), the data-switching of coming serial data NDS is carried out transformation from serial to parallel.By this, serial data NDS can be converted into a plurality of shows signal S
25～S
28265～268 of luminescence components can be according to shows signal S
25～S
28And produce corresponding light source.
In the present embodiment, because latch cicuit 221 exportable serial data NDS, so latch cicuit 221 and 222 cascades each other on electrical, and then cause servo-drive system 200 can utilize more luminescence component to do demonstration.Relatively, being familiar with this operator also can be according to the spirit of present embodiment, and the more latch cicuit of cascade increases the luminescence component that servo-drive system is controlled.
In sum, the present invention utilizes latch cicuit to convert serial data to parallel form.By this, when the number of luminescence component increased, baseboard management controller still only need utilize a universal input and output port to transmit serial data.In addition, the volume of connector can not increase along with the increase of luminescence component number thereupon yet.Therefore, the present invention can reduce the cost of manufacture of servo-drive system effectively, and causes baseboard management controller that the more universal input and output port of multiresidue can be arranged, and sends out in order to carry out the control signal of other function.
Though the present invention discloses as above with preferred embodiment; Right its is not in order to limit the present invention; Has common knowledge the knowledgeable in the technical field under any; Do not breaking away from the spirit and scope of the present invention, when can doing a little change and retouching, so protection scope of the present invention is when being as the criterion with what claim defined.
