See also Fig. 2, it is for the power management architecture sketch map of preferred embodiment of the present invention.As shown in Figure 2; Power management architecture 2 comprises: far end supply management system 21, first～the 6th power distribution unit 22a～22f; Wherein each power distribution unit 22a～22f and far end supply management system 21 all have the connecting wireless network function, and according to the operation demand and the distance of placing to each other coupled (link) network that in time constitutes netted (mesh) each other through the connecting wireless network function with Data transmission each other.
In present embodiment; Far end supply management system 21 links through connecting wireless network function and the first power distribution unit 22a, second source allocation units 22b, the 4th power distribution unit 22d and the 6th power distribution unit 22f, and whether first～the 6th Digital Data Processing Equipment 23a～23f (for example current consuming apparatus such as computer or server) that far end supply management system 21 each power distribution unit 22a～22f of management are connected moves.And the connection relationship of the net like that is constituted between first～the 6th power distribution unit 22a～22f is as follows, but not as limit:
(1)22a：21、22b、22c；
(2)22b：21、22a、22c、22f；
(3)22c：22a、22b；
(4)22d：21、22e、22f；
(5)22e：22d、22f；
(6)22f：21、22b、22d、22e；
Connection relationship by above-mentioned (1), (3) can be known; The first power distribution unit 22a links through connecting wireless network function and far end supply management system 21, second source allocation units 22b and the 3rd power distribution unit 22c; And the 3rd power distribution unit 22c links with the first power distribution unit 22a and second source allocation units 22b through the connecting wireless network function; Though 21 of the 3rd power distribution unit 22c and far end supply management systems directly do not link, 21 of the 3rd power distribution unit 22c and far end supply management systems can be passed through second source allocation units 22b Data transmission each other.
Because; Not that mode with hierarchy type links each other between far end supply management system 21, first～the 6th power distribution unit 22a～22f; But realize netted coupled network through wireless mode; Therefore; First～the 6th rack 24a～24f that places first～the 6th Digital Data Processing Equipment 23a～23f (for example computer or server) and first～the 6th power distribution unit 22a～22f need or not be grid line wiring worries when the designer builds data center because of grid line wiring restriction is placed on position adjacent each other.
In addition; Far end supply management system 21 and power distribution unit 22a～22f in the power management architecture 2 of the present invention are different from traditional operational mode; When operation; Far end supply management system 21 meeting elder generation transmission first enactment document (profile) separately is to first～the 6th power distribution unit 22a～22f; The operation that first control unit (not shown) that makes each power distribution unit 22a～22f is immediately controlled power distribution unit voluntarily according to management strategy that writes down in first enactment document separately and/or principle, wherein each power distribution unit is resent to far end supply management system 21 with each self-monitoring condition information record or after handling earlier according to management strategy that is write down in first enactment document of being obtained by far end supply management system 21 and/or principle.Therefore; Far end supply management system 21 of the present invention does not need immediately to receive all instant condition informations that first～the 6th power distribution unit 22a～22f is detected; More do not need operation according to the immediately corresponding control power distribution unit of all instant condition informations of instant each power distribution unit 22a～22f that receives, promptly do not need to receive continually and transfer control instruction to each power distribution unit 22a～22f.
For example; In when operation, first control unit (not shown) of the first power distribution unit 22a can according to the management strategy that is write down in first enactment document of obtaining by far end supply management system 21 and/or principle voluntarily immediately the supply socket of the control control first power distribution unit 22a whether supply power to the first Digital Data Processing Equipment 23a that is connected and make its operation.In present embodiment; Because the record first power distribution unit 22a power-on time is 06:00～22:00 in first enactment document; So first control unit (not shown) of the first power distribution unit 22a can be voluntarily made first Digital Data Processing Equipment 23a operation by the supply socket power supply to the first Digital Data Processing Equipment 23a that connected in 06:00～22:00, and stop power supply to the first Digital Data Processing Equipment 23a in 22:00～06:00 voluntarily and make the first Digital Data Processing Equipment 23a out of service.Yet; The conventional power source management framework but need be by management system immediately in 06:00～22:00 transfer control instruction to conventional power source allocation units; Supply socket with control conventional power source allocation units is supplied power to the Digital Data Processing Equipment that is connected; Continue; Stopping power supply to the Digital Data Processing Equipment that is connected through the supply socket of the control of transfer control instruction to conventional power source allocation units immediately conventional power source allocation units in 06:00～22:00 makes Digital Data Processing Equipment out of service, and therefore, the operational mode of power management architecture 2 of the present invention obviously is different from the conventional power source management framework.
In addition for example; When operation; The first power distribution unit 22a can immediately detect some condition informations; For example the present output electric weight of each supply socket of power distribution unit, have those supply sockets supplying power or stopping power supply etc. at present, be different from the conventional power source management framework, the first power distribution unit 22a is resent to far end supply management system 21 with the condition information record or after handling earlier according to management strategy that is write down in first enactment document and/or principle.In present embodiment; One detection time of the every interval of the first power distribution unit 22a; For example 1m (in the least) second; Can detect present output electric weight and the output current of each supply socket; And be stored in first storage element or the first memory (not shown) of the first power distribution unit 22a, and average output electric weight and average output current that output electric weight that more utilizes these different times and write down and output current calculate each supply socket, or the output electric weight and the output current that utilize these different times to write down are drawn out output electric weight historigram file and output current historigram file corresponding to time shaft.Afterwards; One turnaround time in every interval; For example 10 minutes, or far end supply management system 21 is when the first power distribution unit 22a require to transmit, the first power distribution unit 22a just can be compressed into the condition information compressed file with condition informations such as output electric weight that these different times write down and output currents; And be sent to far end supply management system 21, with effective minimizing data quantity transmitted.
In some embodiment; One turnaround time of every interval, power distribution unit 22a～22f more can look demand optionally with the condition information compressed file, on average export electric weight, average output current, output electric weight historigram file with and data message such as output current historigram file be sent to far end supply management system 21.Because; Each power distribution unit 22a～22f can just will not be sent to far end supply management system 21 than the instant condition information of small data quantity at every interval one detection time immediately; And far end supply management system 21 can be at every interval yet one detection time just according to the corresponding immediately transfer control instruction of condition information of separately power distribution unit 22a～22f to corresponding power distribution unit 22a～22f; Make and can not transmit a large amount of instant condition information and control command continually in the network; But when the data volume that condition information writes down or storage arrival is bigger; Just the condition information with these different times is sent to far end supply management system 21; Therefore, when power management architecture of the present invention 2 realized that far end supply management systems 21 correctly and are immediately managed whole power supply, the network digital data transmission efficiency was higher in the netted coupled network.
Moreover; Far end supply management system 21 of the present invention is in when operation because the data volume that numeral is transmitted in (1) netted coupled network is less, between (2) each power distribution unit be not social strata relation but connection relationship, (3) far end supply management system 21 of net like do not need immediately (one detection time of every interval) receive all instant condition informations, (4) far end supply management system 21 that each power distribution unit 22a～22f detected do not need immediately (one detection time of every interval) according to the immediately corresponding move instruction of all instant condition informations of instant each power distribution unit 22a～22f that receives to each power distribution unit 22a～22f to control the operation of each power distribution unit 22a～22f.So whole optimized process need not considered the social strata relation of each power distribution unit, the digital data transfer efficient of network and the operation characteristic of the current consuming apparatus that each power distribution unit connected, optimized process is simple and be easy to realize.In like manner, far end supply management system 21 can be selected hardware such as processor, memory (RAM) or the hard disk realization that processing speed is slow, price is cheap and power consumption is lower for use.
