The present invention relates to the technical field of power device, and more particularly, to an IP address display device suitable for a power device, and a power distribution unit and an uninterruptible power system using the same.
At present, power devices, such as power distribution units (PDUs) and uninterruptible power systems (UPSs), have been widely used in various types of equipment rooms (e.g., data centers), so as to distribute power and provide backup power to different equipment in the equipment rooms, respectively. In addition, most of such power devices have network interfaces for remote management.
However, since multiple power distribution units and multiple uninterruptible power systems are commonly used in an equipment room, how to quickly obtain the IP addresses (Internet protocol addresses) of these power devices for remote management has become an important issue.
An object of the present invention is to provide an IP address display device suitable for a power device. When the IP address display device determines that an IP address allocated by a DHCP server (dynamic host configuration protocol server) has been obtained, the IP address display device automatically displays the obtained address.
Another object of the present invention is to provide a power distribution unit adopting the aforementioned IP address display device.
Still another object of the present invention is to provide an uninterruptible power system adopting the aforementioned IP address display device.
To achieve the above object, the present invention provides an IP address display device suitable for a power device. The IP address display device comprises a communication interface, a display interface, and a control circuit. The control circuit is electrically coupled to the communication interface and the display interface, and is used to determine whether an IP address allocated by a DHCP server has been obtained through the communication interface. When the determination result is yes, the control circuit automatically displays the obtained IP address by the display interface for a preset time.
To achieve the above object, the present invention further provides a power distribution unit. The power distribution unit comprises a communication interface, a display interface, and a control circuit. The control circuit is electrically coupled to the communication interface and the display interface, and is used to determine whether an IP address allocated by a DHCP server has been obtained through the communication interface. When the determination result is yes, the control circuit automatically displays the obtained IP address by the display interface for a preset time.
To achieve the above object, the present invention further provides an uninterruptible power system. The uninterruptible power system comprises a communication interface, a display interface, and a control circuit. The control circuit is electrically coupled to the communication interface and the display interface, and is used to determine whether an IP address allocated by a DHCP server has been obtained through the communication interface. When the determination result is yes, the control circuit automatically displays the obtained IP address by the display interface for a preset time,
In order to make the above objects, technical features and gains after actual implementation more obvious and easy to understand, in the following, the preferred embodiments will be described with reference to the corresponding drawings and will be described in more detail.

One of the conductors 102 is used to electrically couple an AC power source L, and the other conductor 102 is used to electrically couple a neutral line N. Each outlet 108 is electrically coupled to the neutral line N through one of the conductors 102, and each outlet 108 is electrically coupled to the AC power source L sequentially through one of the sensing units 106, one of the switch units 104 and the other conductor 102. The coupling manners of the outlets 108 described above are not used to limit the present invention. For example, each outlet 108 can be electrically coupled to the AC power source L through one of the conductors 102, and each outlet 108 can be electrically coupled to the neutral line N sequentially through one of the sensing units 106, one of the switch units 104 and the other conductor 102.
In addition, an input of the AC-DC conversion circuit 110 is electrically coupled to the two conductors 102. As for the control circuit 114, it is electrically coupled with an output of the AC-DC conversion circuit 110, the memory unit 120, the input interface 122, the display interface 116, the communication interface 118, each switch t 104 and each sensing unit 106. Each sensing unit 106 is used to measure current and accordingly provide a sensing result (as shown by D1 to DN, respectively, where N is a natural number). In this way, the control circuit 114 can calculate a corresponding loading according to each sensing result. The control circuit 114 is also used to output control signals C1 to CN, where N is a natural number, so as to control the on/off state of the switch units 104, respectively. In addition, the above-mentioned input interface 122 is used for a user to operate the display interface 116, and is used for the user to directly input a control command to the control circuit 114. Furthermore, the above-mentioned communication interface 118 can be a wired communication interface or a wireless communication interface, and the present invention is not limited thereto.
Next, the control circuit 114 determines whether a network has been connected through the communication interface 118 (as shown in step S204). In step S204, when the determination result is no, the control circuit 114 returns to step S202. On the other hand, when the determination result is yes, the control circuit 114 further determines whether an IP address allocated by a DHCP server has been obtained through the communication interface 118 (as shown in step S206).
In step S206, when the determination result is no, the control circuit 114 returns to step S202. On the other hand, when the determination result is yes, the control circuit 114 automatically displays the obtained IP address by the display interface 116 for a preset time (as shown in step S208).
From the above description, it can be seen that when the IP address display device 112 determines that an IP address allocated by a DHCP server has been obtained, the IP address display device 112 automatically displays the obtained IP address, so that a user can quickly obtain the IP address of the power distribution unit 100 for remote management.
In addition, for flexibility in operations, the control circuit 114 can receive a control command transmitted by a user through the input interface 122 or the communication interface 118, and adjust the length of the preset time accordingly, or determine whether to enable the function of automatically displaying the obtained IP address accordingly. It is worth mentioning that although in this embodiment the power distribution unit 100 adopts a plurality of switch units 104, a plurality of sensing units 106, a memory unit 120, and an input interface 122, however, whether to adopt these components in the power distribution unit 100 can be determined based on actual design requirements.

As for the control circuit 522, it is electrically coupled to the switch unit 504, the first voltage conversion circuit 506, the second voltage conversion circuit 508, the switch unit 510, the charging circuit 514, the sensing circuit 518, the display interface 524, the communication interface 526, the memory unit 528, and the input interface 530, so as to control the operation of these components. For example, the control circuit 522 can control the first voltage conversion circuit 506 to perform a DC-DC voltage conversion operation or an AC-DC voltage conversion operation, and control the second voltage conversion circuit 108 to perform a DC-AC voltage conversion operation. In addition, the control circuit 522 can control the switch unit 504 to transfer the output of the filtering unit 502 to the first voltage conversion circuit 506 or the bypass path 532, or control the switch unit 504 to transfer the output of the battery 516 to the first voltage conversion circuit 506. Further, the control circuit 522 can control the switch unit 510 to transfer the output of the second voltage conversion circuit 508 to the filtering unit 512, or control the switch unit 510 to electrically couple the bypass path 532 to the filtering unit 512.
In addition, the above-mentioned input interface 530 is used for a user to operate the display interface 524, or for the user to directly input a control command to the control circuit 522. Furthermore, the above-mentioned communication interface 526 can be a wired communication interface or a wireless communication interface, and the present invention is not limited thereto.
Referring to
Next, the control circuit 522 determines whether a network has been connected through the communication interface 526 (as shown in step S204). In step S204, when the determination result is no, the control circuit 522 returns to step S202. On the other hand, when the determination result is yes, the control circuit 522 further determines whether an IP address allocated by a DHCP server has been obtained through the communication interface 526 (as shown in step S206).
In step S206, when the determination result is no, the control circuit 522 returns to step S202. On the other hand, when the determination result is yes, the control circuit 522 automatically displays the obtained IP address by the display interface 524 for a preset time (as shown in step S208).
From the above description, it can be seen that when the IP address display device 520 determines that an IP address allocated by a DHCP server has been obtained, the IP address display device 520 automatically displays the obtained IP address, so that a user can quickly obtain the IP address of the uninterruptible power system 500 for remote management.
In addition, for flexibility in operations, the control circuit 522 can receive a control command transmitted by a user through the input interface 530 or the communication interface 526, and adjust the length of the preset time accordingly, or determine whether to enable the function of automatically displaying the obtained IP address accordingly. It is worth mentioning that although in this embodiment the uninterruptible power system 500 adopts the filtering unit 502, the filtering unit 512, the memory unit 528, and the input interface 530, however, whether to adopt these components in the uninterruptible power system 500 can be determined based on actual design requirements. Furthermore, although
In summary, when the IP address display device determines that an IP address allocated by a DHCP server has been obtained, the IP address display device automatically displays the obtained IP address, so that a user can quickly obtain the IP address of the power device (e.g., power distribution unit, uninterruptible power system) adopting the IP address display device for remote management.
