Description

Power distribution unit and power management system applicable to same

Technical Field

The invention relates to a power distribution unit and a power management system applicable to the same.

Background

With the progress of computer technology and the rapid development of internet, more and more services or functions are provided through internet, so that Data centers (Data centers) for cloud computing composed of a plurality of computers or servers are rapidly increasing, the number of computers or servers in the Data centers must be increased in order to provide more services or functions on internet, and the problems of power supply, distribution and management of the Data centers are also followed. In order to solve the problems of Power supply, Distribution, Management and the like of the data center, the data center distributes Power required by each computer or server by using a Power Distribution Unit (PDU), and manages whether each Power Distribution Unit supplies Power to the connected computer or server by using a Remote Power Management System (Remote Power Management System), so that the overall Power utilization efficiency of the data center is optimized.

Referring to fig. 1 and 2, fig. 1 is a schematic diagram of a power management architecture of a conventional data center, and fig. 2 is a block diagram of a power management system of a conventional data center. As shown in fig. 1 and 2, a conventional power management architecture 1 of a data center mainly includes a plurality of area management units, for example: the first area management unit 131 and the second area management unit 132 enable different groups of power distribution units, such as: the first group of power distribution units 141 and the second group of power distribution units 142 can be connected to the power management system 11, and as shown in fig. 1, the remote power management system 11 can manage whether the computers or

servers

151, 152, 153 connected to each of the

power distribution units

141a, 141b, and 141c of the first group of power distribution units 141 are operating or not through the connection of the first local management unit 131. The data center has a plurality of computers or

servers

151, 152, 153 stacked in the cabinets 16, and each data center has a plurality of cabinets 16, so as to form a cloud computing data center composed of the plurality of computers or

servers

151, 152, 153. As shown in fig. 1 and 2, each computer or

server

151, 152 and 153 is electrically connected to the corresponding

power distribution unit

141a, 141b and 141c, however, each

power distribution unit

141a, 141b and 141c is not limited to be connected to only one computer or

server

151, 152 and 153, for example, the power distribution unit 141a has a plurality of sockets, so that it can be connected to a plurality of computers or servers (not shown) in addition to the corresponding computer or server 151. Each socket of the

power distribution units

141a, 141b, 141c may be provided with a switch element (not shown), so that the power management, distribution and control of the plurality of computers or

servers

151, 152 and 153 can be realized by controlling the on and off of the switch elements.

As shown in fig. 2 and described above, the conventional power management system 1 includes a first local power management unit 131 and a second local power management unit 132. And the power distribution units can be divided into a first group of power distribution units 141 and a second group of power distribution units 142. The first group of power distribution units 141 includes a plurality of

power distribution units

141a, 141b, 141c, which are grouped together and directly associated with the local power management unit 131 so that all the power distribution units 141 have a dedicated and single IP address. Similarly, the second group of power distribution units 142 also includes a plurality of

power distribution units

142a, 142b, 142c, which are grouped together and associated with the second local power management unit 132, such that all of the power distribution units 142 have a dedicated and single other IP address. The first local power management unit 131 and the second local power management unit 132 can also directly communicate with the remote power management system 11 through the ip network 12. When the remote power management system 11 communicates with the first local power management unit 131 and the second local power management unit 132 and transmits the command, it uses an IP communication protocol with a single IP address for each local

power management unit

131, 132. In this way, although the first local power management unit 131 and the second local power management unit 132 are connected to integrate the power usage information of the

power distribution units

141 and 142 of different groups, the response time and the data transmission amount on the IP network can be saved.

However, in the prior art, if one of the local power management units, for example: when the first local power management unit 131 fails or is damaged, the different groups of power distribution units 141 connected to the first local power management unit cannot communicate and communicate with the remote power management system 11 through the network channel, that is, the remote power management system 11 cannot obtain the operation information of each computer or

server

151, 152, 153 through the network channel, and cannot correspondingly control the corresponding

power distribution units

141a, 141b, and 141c, so that the purpose of managing the entire power by the remote power management system 11 cannot be achieved. Meanwhile, when the remote power management system 11 cannot obtain the operation information of the computer or the

server

151, 152, 153 through the network channel, it needs to further confirm and detect whether the network cannot be connected or the computer or the

server

151, 152, 153 is failed, damaged or crashed, which also increases the trouble of power management. Therefore, not only the trouble of maintenance and management operation is caused, but also much time and cost for detection and maintenance are wasted.

Referring to fig. 6C, in the present embodiment, the pushing-buckling portion 236 is disposed on an extended top surface 232C of the engaging module 232, and includes a pushing piece 236a and a first groove 236 b; the second locking portion 235 is disposed on the short side surface 232d of the engaging module 232, and the short side surface 232d is opposite to the short side surface 240c of the first locking portion 234, and the second locking portion 235 includes a rod portion 235a and a second groove 235 b. In some embodiments, the short side surface 232d of the engaging module 232 has a groove 232f, and the second locking portion 235 is correspondingly disposed in the groove 232f, but not limited thereto. As shown in fig. 6C, the pushing piece 236a of the pushing-buckling portion 236 is correspondingly disposed in the first groove 236b and can slide in the first groove 236 b; the rod 235a of the second locking portion 235 is also correspondingly disposed in the second groove 235b and can slide in the second groove 235b, and the pushing piece 236a of the pushing-buckling portion 236 is linked with the rod 235a of the second locking portion 235; therefore, when the user pushes the pushing piece 236a to slide in the first groove 236B, since the pushing piece 236a is interlocked with the rod 235a of the second locking portion 235, the rod 235a is also interlocked with the rod 235a to slide relatively in the second groove 235B, and the first locking portion 234 can be correspondingly set at different initial positions P1, locking positions P2 or unlocking positions P3 (as shown in fig. 7A and 7B) by the sliding position of the rod 235a in the second groove 235B and the relative position between the first hook 234a and the second hook 234B of the first locking portion 234.

Referring to fig. 7A and 7B, first, as shown in fig. 7A, it shows the relative action relationship between the first locking portion 234 and the second locking portion 235 when the hot-swap intelligent module 24 is downwardly disposed from the position shown in fig. 6B into the accommodating space 232e of the engaging module 232, as shown in fig. 7A, when the hot-swap intelligent module 24 is downwardly disposed due to the force of the user and the first locking portion 234 on the short side 240c of the hot-swap intelligent module 24 contacts with the second locking portion 235 on the short side 232d of the engaging module 232, the rod portion 235a of the second locking portion 235 is first disposed at an initial position P1, and this position P1 is a position where the rod portion 235a contacts with the end of the inclined portion 234a1 of the first hook portion 234 a; then, when the hot-pluggable intelligent module 24 is pressed down continuously in compliance with the force applied by the user, the rod 235a of the second locking portion 235 slides upwards along the inclined surface of the inclined portion 234a1 of the first hook 234a and correspondingly engages with the locking position P2 between the vertical portion 234b1 and the second horizontal portion 234b2 of the second hook 234b, and at this time, the position of the rod 235a is limited by the vertical portion 234b1 and the second horizontal portion 234b2, so that the hot-pluggable intelligent module 24 cannot move freely, and the hot-pluggable intelligent module 24 can be firmly locked in the accommodating space 232e of the engaging module 232. When the user wants to take out the hot-plug intelligent module 24, the user only needs to push the pushing piece 236a of the pushing and buckling part 236 disposed on the extended top surface 232c of the engaging module 232 to slide relative to the first groove 236B, and due to the horizontal pushing force, the linking rod 235a can be displaced toward the inclined part 234a1 of the first hook 234a and slide downward along the inclined surface of the inclined part 234a1 as shown in fig. 7B, and when the linking rod 235a passes over the bottom of the inclined part 234a1, the rod 235a will abut against the bottom surface of the first horizontal part 234a2 of the first hook 234a, i.e., the unlocking position P3 as shown in fig. 7B, so as to generate an upward abutting pushing force, and the hot-plug intelligent module 24 can be pushed by the rod 235a to bounce upward, and thus can bounce and be separated from the engaging module 232. Therefore, the hot-swap intelligent module 24 can be stably locked in the engaging module 232 by the corresponding lock of the first lock portion 234 and the second lock portion 235 of the fastening module 233, and the second lock portion 235 and the first lock portion 234 are driven to unlock by the push-lock portion 236 of the fastening module 233, so that the hot-swap intelligent module 24 can bounce upwards and separate from the engaging module 232, thereby facilitating the installation and removal operations.

Continuing with fig. 6B and fig. 6C, in the present embodiment, the hot-swap intelligent module 24 further has a conductive portion 246, and the conductive portion 246 is disposed at the boundary between the short side 240C and the bottom 240d of the housing 240, and as shown in fig. 6C, the bottom 232B of the engaging module 232 has a hollow hole 232g, and the position of the hollow hole 232g corresponds to the conductive portion 246 of the hot-swap intelligent module 24, so that when the hot-swap intelligent module 24 is correspondingly disposed in the engaging module 232, the conductive portion 246 can correspondingly penetrate through the hollow hole 232g and electrically connect to another conductive end (not shown) of the power distribution unit 23, so that the hot-swap intelligent module 24 can electrically connect and communicate with the power distribution unit 23. Therefore, the user can freely set the hot-plug intelligent module 24 in the embedded module 232 through the fastening module 233 without turning off the power of the power distribution unit 23, and perform corresponding operations, or can directly take out the hot-plug intelligent module 24 without turning off the power of the power distribution unit 23 when the hot-plug intelligent module 24 needs to be replaced, so as to achieve the effect of easily setting/replacing the hot-plug intelligent module 24.
