Title: Uninterruptible power supply

Description:
FIELD OF THE INVENTION 
     The present invention relates to an uninterruptible power supply which controls sequence of power to electric apparatuses from the storage batteries based on using requirements. 
     BACKGROUND OF THE INVENTION 
     A conventional uninterruptible power supply (UPS) contains at least one storage battery electrically connected with a power source and a socket on which at least one electric apparatus is coupled, such that when power is failed, the storage battery supplies the power to the electric apparatus. Preferably, a number of the at least one storage battery determines based on that of the at least one electric apparatus. However, the conventional uninterruptible power supply has following defects: 
     1. When one of the at least one storage battery is broken, the other storage batteries cannot supply the power to the at least one electric apparatus. 
     2. The at least one storage battery can only supply the power to its corresponding electric apparatus. 
     3. Wiring configuration of each of the at least one storage battery has to be changed, as desiring to supply the power to the other electric apparatuses. 
     4. The conventional uninterruptible power supply (UPS) cannot control power supply by using wireless signals. 
     The present invention has arisen to mitigate and/or obviate the afore-described disadvantages. 
     SUMMARY OF THE INVENTION 
     The primary objective of the present invention is to provide an uninterruptible power supply which controls sequence of power to the electric apparatuses from the storage batteries based on using requirements. 
     To obtain above-mentioned objective, an uninterruptible power supply provided by the present invention contains: a plurality of power control devices, a cloud main controller, and multiple plugs. 
     The plurality of power control devices are in connection with a power source, and the plurality of power control devices include cloud power management controllers, storage batteries, code readers, and sockets, respectively. The multiple plugs have code setters, individually. The cloud main controller sets power supply sequence to the cloud power management controllers of the plurality of power control devices as power failure occurs, and the cloud power management controllers control conductivity and interruption of power supply to the storage batteries. The code readers of the plurality of power control devices read sequence codes of the code setters respectively.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     With reference to the FIGURE, an uninterruptible power supply according to a preferred embodiment of the present invention comprises: a plurality of power control devices  200 , a cloud main controller  20 , and multiple plugs  30   a ,  30   b ,  30   c . The plurality of power control devices  200  are in connection with a power source  10 , and the plurality of power control devices  200  include cloud power management controllers  20   a ,  20   b ,  20   c , storage batteries  11   a ,  11   b ,  11   c , code readers  21   a ,  21   b ,  21   c , and sockets  12   a ,  12   b ,  12   c , respectively. The multiple plugs  30   a ,  30   b ,  30   c  have code setters  31   a ,  31   b ,  31   c , individually. The cloud main controller  20  sets power supply sequence to the cloud power management controllers  20   a ,  20   b ,  20   c  of the plurality of power control devices  200  as power failure occurs, and the cloud power management controllers  20   a ,  20   b ,  20   c  control conductivity and interruption of power supply to the storage batteries  11   a ,  11   b ,  11   c . The code readers  21   a ,  21   b ,  21   c  of the plurality of power control devices  200  read sequence codes of the code setters  31   a ,  31   b ,  31   c  respectively. Furthermore, the cloud main controller  20  controls the cloud power management controllers  20   a ,  20   b ,  20   c  and the plugs  30   a ,  30   b ,  30   c  by using wireless signals or wired signals, individually. 
     Thereby, when the power source  10  is failed, the uninterruptible power supply of the present invention operates as follows: 
     1. The cloud main controller  20  controls the cloud power management controllers  20   a ,  20   b ,  20   c  to electrically conduct with the storage batteries  11   a ,  11   b ,  11   c , respectively, hence the storage batteries  11   a ,  11   b ,  11   c  supply power to electric apparatuses  1 ,  2 ,  3 , individually. 
     2. As supplying the power to electric apparatus  1  in large power capacity, the cloud main controller  20  controls the power supply to the code setter  31   a  of the plug  30   a  in priority. As the power source is failed, the cloud power management controllers  20   a ,  20   b ,  20   c  of the plurality of power control devices  200  control the power to the electric apparatus  1  from the storage batteries  11   a ,  11   b ,  11   c  in priority. 
     3. The uninterruptible power supply of the present invention controls sequence of the power to the electric apparatuses  1 ,  2 ,  3  from the storage batteries  11   a ,  11   b ,  11   c  based on using requirements. 
     4. The cloud main controller  20  is connected with network via a computer so as to control the power sequence to the cloud power management controllers  20   a ,  20   b ,  20   c  by using the wireless signals. 
     While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
