Abstract

A method for controlling power distribution unit (PDU) by an uninterruptible power supply (UPS) has steps of allowing logging in the UPS through a network, providing a web-based user interface and allowing adding an identification of at least one PDU to use sockets on the added PDU to simulate additional sockets on the UPS, performing a handshaking task with the added PDU, receiving information from the added PDU during performing of the handshaking task, displaying the received information of the added PDU on the web-based user interface and allowing either operating the UPS or controlling the added PDU. The method allows the UPS to be capable of communicating with all connected PDUs so the user can merely login the UPS to control and manage all PDUs connected to the UPS.

First claim

What is claimed is:

1. A method for controlling power distribution unit (PDU) by an uninterruptible power supply (UPS) comprising steps of:
allowing logging in the UPS through a network;
providing a web-based user interface and allowing adding an identification of at least one PDU to use sockets on the added PDU to simulate additional sockets on the UPS;
performing a handshaking task with the added PDU;
receiving information from the added PDU during performing of the handshaking task;
displaying the received information of the added PDU on the web-based user interface; and
allowing either operating the UPS or controlling the added PDU.

2. The method as claimed in claim 1 , wherein the step of allowing either operating the UPS or controlling the added PDU further comprises sub-acts of:
determining whether the UPS issues a control command;
determining whether the control command is related to the added PDU when receiving the control command;
operating according to the control command by the UPS if the control command is not related to the added PDU;
transmitting the control command to the added PDU via the network if the control command is related to the added PDU so the added PDU operates according to the control command.

3. A UPS applying the method as claimed in claim 1 comprising:
multiple sockets, and each socket provided for electrically connecting to either one electrically-powered apparatus or one PDU;
a controller electrically connected to the sockets and providing a web-based user interface, and the web-based user interface having
a virtual socket setting page provided for adding an identification of at least one PDU to use sockets on the added PDU to simulate additional sockets on the UPS; and
a display and control page provided for either operating the UPS or controlling the added PDU; and

at least one network interface electrically connected to the controller.

4. The UPS as claimed in claim 3 , wherein the virtual socket setting page comprises:
a first registered IP display field provided for displaying an IP address of the UPS;
a new equipment input field provided for adding an identification of a new PDU to use sockets on the added PDU to simulate additional sockets on the UPS; and
a name input field provided for adding a name of the newly added PDU.

5. The UPS as claimed in claim 4 , wherein the display and control page comprises:
a second registered IP display field provided for displaying an IP address of the UPS;
a host information field provided for displaying various information of the UPS and providing multiple control functions for controlling the UPS; and
at least one virtual socket field corresponding to one added PDU and provided for displaying connection statuses of the sockets on a corresponding PDU and provided for a user to control the sockets of the corresponding PDU.

6. The UPS as claimed in claim 5 , wherein the at least one virtual socket field comprises:
a control command option provided for the user to choose to issue a control command to the corresponding PDU to control the sockets on the corresponding PDU; and
a socket information menu displaying the received information of each socket of each power distribution unit and having multiple checkboxes, and the checkboxes corresponding respectively to the sockets of the corresponding PDU and provided for the user to make selection from the sockets of the corresponding PDU so the selected sockets are controlled based on the control command.

7. The UPS as claimed in claim 4 , wherein the host information field and the virtual socket field display loading status information provided for displaying a rated current and a working current of the UPS and the added PDU.

8. The UPS as claimed in claim 5 , wherein the new equipment input field is implemented by a drop-down list.

9. The UPS as claimed in claim 3 , wherein the identification is chosen from an IP address, a media access control address or series number of a PDU.

10. The UPS as claimed in claim 3 , wherein the network interface is chosen from being implemented in a wired protocol or a wireless protocol.

11. A UPS applying the method as claimed in claim 2 comprising:
multiple sockets, and each socket provided for electrically connecting to either one electrically-powered apparatus or one PDU;
a controller electrically connected to the sockets and providing a web-based user interface, and the web-based user interface having
a virtual socket setting page provided for adding an identification of at least one PDU to use sockets on the added PDU to simulate additional sockets on the UPS; and
a display and control page provided for either operating the UPS or controlling the added PDU; and

at least one network interface electrically connected to the controller.

12. The UPS as claimed in claim 11 , wherein the virtual socket setting page comprises:
a first registered IP display field provided for displaying an IP address of the UPS;
a new equipment input field provided for adding an identification of a new PDU to use sockets on the added PDU to simulate additional sockets on the UPS; and
a name input field provided for adding a name of the newly added PDU.

13. The UPS as claimed in claim 12 , wherein the display and control page comprises:
a second registered IP display field provided for displaying an IP address of the UPS;
a host information field provided for displaying various information of the UPS and providing multiple control functions for controlling the UPS; and
at least one virtual socket field corresponding to one added PDU and provided for displaying connection statuses of the sockets on a corresponding PDU and provided for a user to control the sockets of the corresponding PDU.

14. The UPS as claimed in claim 13 , wherein the at least one virtual socket field comprises:
a control command option provided for the user to choose to issue a control command to the corresponding PDU to control the sockets on the corresponding PDU; and
a socket information menu displaying the received information of each socket of each power distribution unit and having multiple checkboxes, and the checkboxes corresponding respectively to the sockets of the corresponding PDU and provided for the user to make selection from the sockets of the corresponding PDU so the selected sockets are controlled based on the control command.

15. The UPS as claimed in claim 12 , wherein the host information field and the virtual socket field display loading status information provided for displaying a rated current and a working current of the UPS and the added PDU.

16. The UPS as claimed in claim 13 , wherein the new equipment input field is implemented by a drop-down list.

17. The UPS as claimed in claim 11 , wherein the identification is chosen from an IP address, a media access control address or series number of a PDU.

18. The UPS as claimed in claim 11 , wherein the network interface is chosen from being implemented in a wired protocol or a wireless protocol.
