Description

A centralized control rPDU system Technical Field

[0001] The present invention relates to the technical field of power distribution, and in particular to a centralized control type rPDU system. Background Art

[0002] The rPDU (Remote Power Distribution Unit), also known as a network power control system, remote power management system, intelligent PDU, or intelligent power distribution system, is a power distribution system that enables remote control and planned management. It is primarily used to control power supply to data centers, equipment control centers, and weak current distribution network centers at all levels. The rPDU is an industrial-grade intelligent power distribution control unit designed specifically for IDCs, ICPs, ISPs, and enterprise and institution data centers or equipment control centers, as well as their remote locations. It integrates power distribution, isolation, grounding, monitoring, and management in the computer room, significantly improving the security of the computer room's power supply system.

[0003] The most basic function of an rPDU is similar to that of a power socket: it can power devices. It also offers powerful features such as connection, query, monitoring, filing, and intelligent management. It can be used for devices that previously received power through sockets, terminal blocks, or terminal posts.

[0004] Currently, the rPDU on the market generally consists of a display control module, a power module, and a branch module. These modules are connected via the RS485 bus or CAN bus. The principle is shown in Figure 1.

[0005] The main control module includes display and monitoring functions. It is mainly responsible for collecting and summarizing the detection data of the power module and branch modules, transmitting on-site information through the human-machine interface and remote information transmission through the network. It is responsible for receiving on-site and remote commands, and according to the commands, controls the branch modules to manage the output bits.

[0006] The power module includes power supply and main circuit monitoring functions. It is mainly responsible for supplying power to the main control module and branch circuit modules, monitoring the input end, and uploading the monitoring data to the main control module.

[0007] The branch module includes output bit control and output bit monitoring functions. It is mainly responsible for monitoring the output bit and uploading the monitoring data to the main control module. It is also responsible for receiving instructions from the main control module and managing the output bit according to the instructions.

[0008] The current rPDU design consists of one main control module, one power module, and one to four branch modules. The branch modules are located below or to the sides of the outlets. One branch module can monitor and control multiple outlets. The current rPDU structure is shown in Figure 2 below.

[0009] The existing design has the following defects:

[0010] (1) Low resource utilization of the main control module: The main control module has very powerful performance. The main control module based on RS485 bus / CAN bus connection can control 256 modules (power modules, branch modules). The existing design only controls 5 modules, and the remaining resources are completely wasted.

[0011] (2) Socket resources are wasted: The main control module and power module occupy about 7 sockets. With the increasing demand for sockets, the socket resources occupied by the main control module and power module are even more wasted;

[0012] (3) Slow communication speed and sluggish control response: Existing rPDUs generally use RS485 communication, which has an extremely slow communication speed. From the time the host computer issues a command to the time the control response is completed, the theoretical response time exceeds 2 seconds, which is not conducive to immediate response.

[0013] (4) High overall power consumption: The main control module consumes a lot of power. Each rPDU is equipped with a main control module, and the cumulative energy consumption is very high, which is not conducive to energy conservation and emission reduction;

[0014] (5) Local high temperature: A single centralized power module provides power, resulting in obvious local high temperature areas in the power module area. This creates a lot of heat dissipation pressure and may even cause the rPDU to be damaged by the local high temperature.

[0015] (6) The strong and weak currents are paralleled over a large span, which is prone to interference: The power supply and communication between the main control module, power module, and socket + branch modules are connected by electronic cables. These electronic cables and high-voltage cables are paralleled over a large span inside the rPDU. There are also large spans of parallel connection between the strong and weak current lines, and between the strong and signal lines, which are prone to mutual interference and have a high possibility of interference.

[0016] (7) Complex structure, high production difficulty, and high failure rate: The internal space of the rDPU is very narrow, and there is a serious space constraint. A large number of functional modules need to be integrated in the narrow and severely constrained space, which inevitably leads to a complex structure. The complex structure inevitably leads to great production difficulty. The high production difficulty inevitably leads to low pass rate and high failure rate.

[0017] (8) Complex production and debugging: In the existing design, three sets of protocols are running simultaneously inside the rPDU, which complicates the debugging process, further increasing the difficulty of production and reducing the yield rate;

[0018] (9) High cost: The main control module is expensive, has a complex structure, is difficult to produce, is complex to debug, and has high power consumption, resulting in a series of high costs such as material cost, production cost, debugging cost, after-sales cost, and usage cost;

[0019] (10) It is not conducive to the overall layout of the computer room: Each rPDU needs to be connected to the host computer through a network cable. A large number of network cables will cause the overall layout of the computer room to be messy, increase the difficulty of the computer room layout, and also increase the difficulty of subsequent maintenance.

[0020] Summary of the Invention

[0021] The present invention provides a centralized control type rPDU system, aiming to solve the defects existing in the existing rPDU design.

[0022] The present invention provides a centralized control type rPDU system, including a main control platform and rPDU components. The main control platform controls at least one rPDU component, and the rPDU component includes at least one power socket module.

The main control platform includes a main control wireless communication module, and the main control wireless communication module establishes a wireless connection with the socket wireless communication module of each power socket module respectively. The main control platform is independently connected to the mains power supply.

[0023] As a further improvement of the present invention, each of the power socket modules also includes multiple socket output positions and multiple branch modules. The socket output positions are connected one-to-one with the branch modules, and the multiple branch modules are respectively connected to the socket wireless communication module and the small power module.

[0024] As a further improvement of the present invention, the branch module is responsible for monitoring the socket output position and uploading the monitoring data to the main control platform through the socket wireless communication module; and the branch module is also responsible for receiving instructions from the main control platform through the socket wireless communication module and managing the socket output position according to the instructions.

[0025] As a further improvement of the present invention, the small power supply module is responsible for supplying power to the branch module; it is also responsible for monitoring the power input end and uploading the monitoring data to the main control platform through the socket wireless communication module.

[0026] As a further improvement of the present invention, the rPDU assembly also includes a power plug, to which the small power module of each power socket module is individually connected, and the power plug is connected to the mains power supply.

[0027] As a further improvement of the present invention, the main control platform is a control device independent of the rPDU components, each of the rPDU components is an independent socket device, and the main control platform is connected to and controls at least one rPDU component via wireless communication.

[0028] As a further improvement of the present invention, each of the rPDU components is installed with at least one power socket module, and the main control platform independently establishes wireless communication with the power socket module of each rPDU component.

[0031] As a further improvement of the present invention, the main control platform further includes a power conversion module, and the main control platform is connected to the mains power supply through the power conversion module.

[0032] As a further improvement of the present invention, the socket wireless communication module of each power socket module has an independent MAC address, and the power socket module uses the MAC address of the socket wireless communication module as its own address. The control method of the main control platform over the power socket module includes:

[0033] Networking mode: The main control platform obtains the MAC addresses of all power socket modules by broadcasting, and records and saves them in the address database;

[0034] Normal working mode: The main control platform sends query instructions and control instructions with MAC address information one by one in a broadcast manner according to the MAC address information stored in the address library, and processes and analyzes the information returned by the power socket module; after the power socket module receives the broadcast information from the main control platform, it first determines whether the MAC address in the broadcast information is the MAC address itself. If it is its own MAC address, it uploads data or performs control operations according to the instruction information. If it is not its own MAC address, it does not respond.

[0042] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0043] As shown in Figures 3 to 6, a centralized control rPDU system of the present invention includes a main control platform 1 and an rPDU component 2. The main control platform 1 controls at least one rPDU component 2. The rPDU component 2 includes at least one power socket module 3. Each power socket module 3 includes an independent small power module 4 and a socket wireless communication module 5. The small power module 4 supplies power to the power socket module 3 separately. The small power module 4 is connected to the socket wireless communication module 5. The main control platform 1 includes a main control wireless communication module 12. The main control wireless communication module 12 establishes a wireless connection with the socket wireless communication module 5 of each power socket module 3 respectively. The main control platform 1 is independently connected to the mains power supply.

[0044] This device separates the original rPDU's main control module, replacing it with a unified master control platform 1 to control the rPDU. It also establishes a wireless communication connection with each power outlet module 3, allowing for direct monitoring of the status of each specific power outlet module 3. This eliminates the need for multiple data conversions, resulting in fast and responsive data. Furthermore, the control of the original rPDU's single power module is decentralized, with each power outlet module 3 equipped with a small power module 4. This allows for independent power supply control for each power outlet module 3, distributing the power modules to different areas. This disperses the heat source, reduces heat dissipation pressure, and addresses the issue of localized overheating that can damage the rPDU.

[0045] As shown in Figure 5, each power socket module 3 also includes multiple socket output positions 7 and multiple branch modules 6. The socket output positions 7 are connected one-to-one with the branch modules 6, and the multiple branch modules 6 are respectively connected to the socket wireless communication module 5 and the small power module 4. Each branch module 6 controls the corresponding socket output position 7 to realize the connection or disconnection between the socket output position 7 and the small power module 4. At the same time, the branch module 6 collects the data information of the corresponding socket output position 7 and transmits it to the main control platform 1 in real time through the socket wireless communication module 5.

[0046] The branch module 6 is responsible for monitoring the socket output position 7 and uploading the monitoring data to the main control platform 1 through the socket wireless communication module 5; and the branch module 6 is also responsible for receiving instructions from the main control platform 1 through the socket wireless communication module 5 and managing the socket output position 7 according to the instructions.

[0047] The small power supply module 4 is responsible for supplying power to the branch module 6 ; it is also responsible for monitoring the power input end and uploading the monitoring data to the main control platform 1 through the socket wireless communication module 5 .

[0048] The rPDU assembly 2 also includes a power plug 8, which connects to the mains power supply for each small power module 4 in each power outlet module 3. Each rPDU assembly 2 is connected to the mains power supply via a single power plug 8, while each small power module 4 is independently powered. This decouples the existing rPDU's overall power module from the mains power supply, providing each power outlet module 3 with its own power supply. There are no weak current connections between power outlet modules 3, eliminating the problem of large-scale parallel operation between strong and weak currents, which can easily cause interference.

[0049] As shown in Figures 3 and 4, the master control platform 1 is a control device independent of the rPDU components 2. Each rPDU component 2 is an independent socket device. The master control platform 1 connects to and controls at least one rPDU component 2 via wireless communication. This improved device only requires a single master control platform 1 to control multiple rPDU components 2 via wireless communication. This makes the master control module on the existing rPDU component 2 independent, freeing up more space for installing socket output positions 7 to better meet socket space requirements. A single master control platform 1 controls multiple rPDU components 2, reducing the average power consumption of each rPDU component 2.

[0050] Each rPDU assembly 2 is equipped with at least one power outlet module 3. The main control platform 1 independently establishes wireless communication with the power outlet module 3 of each rPDU assembly 2. Each power outlet module 3 on the rPDU assembly 2 is an independent module, and each power outlet module 3 can independently exchange information with the main control platform 1. This allows specific control of a power outlet module 3 by operating the main control platform 1, making the control method more flexible and targeted, and solving the problem that all power outlet modules 3 on the rPDU assembly can only be controlled by the main control module.

[0051] As shown in Figure 6, the main control platform 1 includes a central processing unit 11, which is connected to the main control wireless communication module 12. The central processing unit 11 receives data feedback from each power socket module 3 through the main control wireless communication module 12, and sends instructions to each power socket module 3 through the main control wireless communication module 12.

[0052] The central processing unit 11 is the core of the entire main control platform 1. It is responsible for processing the received data and sending instructions to the power socket modules 3 on different rPDU components 2 according to the user's control needs or set control requirements, controlling the on and off of different power socket modules 3 and the output of the small power module 4, and monitoring the conditions of the branch module 6 and the small power module 4 in real time, and providing real-time feedback on the monitoring situation. The central processing unit 11 is connected to the main control wireless communication module 12 through the connector inside the main control platform 1, and receives data sent by the rPDU component 2 in real time through the main control wireless communication module 12, and sends instructions to the rPDU component 2. The central processing unit 11 is also connected to the buttons and display screen of the main control platform 1 through the connector. The user can input instructions to each power socket module 3 through buttons, WEB operations, etc. The instructions can be query instructions, control instructions, and the situation of each power socket module 3 in the rPDU component 2 is displayed on the display screen in real time.

[0053] The centralized rPDU system also includes a host computer. The master control platform 1 is also equipped with a network conversion module and a network interface. The central processing unit 11 connects to the host computer via the network conversion module, then through a switch and the network interface. The master control platform 1 is connected to the host computer via a network cable and transmits received data to the host computer and receives command data from the host computer. The entire system only requires a single master control platform 1 to connect to the host computer, resolving the problem of existing rPDUs requiring multiple master control modules to be connected to the host computer via network cables, resulting in a complex computer room layout.

[0054] The control platform 1 also includes a power conversion module 13, through which the control platform 1 is connected to the mains power supply. The control platform 1 is independently connected to the mains power supply and does not share power with the rPDU component 2, thus reducing the occupation of the power supply resources of the rPDU component 2.

[0055] The main control platform 1 also includes an RS485 communication module and an RJ45 interface, through which the central processing unit 11 connects to external devices and sensors to implement RS485 serial communication. The main control platform 1 may also include dry contacts and input / output modules for the central processing unit 11 to connect and implement signal input and output.

[0056] The working mode of this centralized control rPDU system is:

[0057] The socket wireless communication module 5 of each power socket module 3 has an independent MAC address, and the power socket module 3 uses the MAC address of the socket wireless communication module 5 as its own address.

[0058] The main control platform 1 has two working modes: networking mode and normal working mode;

[0059] After the system hardware is set up, the system enters the normal working mode by default. The main control platform 1 can be forced to enter the networking mode by pressing buttons, WEB operations, etc.; if there is no operation in the networking mode for a certain period of time, or if reset and restart operations are performed, the system automatically enters the normal working mode.

[0060] In networking mode, the main control platform 1 queries and obtains the MAC addresses of all power socket modules 3 by broadcasting, and records and saves them in the address database;

[0061] In normal operation mode, the main control platform 1 broadcasts query and control instructions containing MAC address information one by one based on the MAC address information stored in the address library, and processes and analyzes the returned information. After all the MAC addresses stored in the address library have been queried and controlled, the next round of query and control continues for all MAC addresses, and this cycle continues. After the power socket module 3 receives the broadcast information, it first determines whether the MAC address in the broadcast information is the MAC address of the power socket module 3 itself. If it is, it uploads data or performs control operations according to the instruction information. If it is not its own MAC address, it does not respond.

[0062] This centralized control rPDU system has the following advantages through design innovation:

[0063] (1) Improve resource utilization. The main control module is separated and made into a separate main control platform 1, which can monitor multiple rPDUs at the same time, thereby doubling resource utilization.

[0064] (2) Free up valuable socket resources. The main control module and power module occupy approximately 7 sockets. By separating the main control module and replacing the power module with a small power module 4 and combining it with the socket & branch module 6 into a socket & branch & small power combination module, 7 sockets can be freed up to better meet socket demand.

[0065] (3) Improve communication speed and control response speed. The main control platform 1 directly monitors each socket position, branch circuit, and small power supply combination module through wireless communication. The data does not need to be converted multiple times, and the speed is fast and the response is sensitive.

[0066] (4) Reduce overall power consumption. A single master control platform 1 controls multiple rPDUs, and the average power consumption of each rPDU is reduced.

[0067] (5) Effectively solve the problem of local high temperature. Distributing power modules to different areas disperses the heat source, reduces heat dissipation pressure, and solves the problem of local high temperature damaging the rPDU.

[0068] (6) Solve the problem of large-span parallel operation between strong and weak currents, which is prone to interference. The power supply modules are dispersed and combined with the socket position & branch module 6 to form a socket position & branch & small power supply combination module. Each combination module is powered independently, and there is no weak current connection between the combination modules, which solves the problem of large-span parallel operation between strong and weak currents, which is prone to interference.

[0069] (7) The structure is relatively simple, reducing production difficulty. The main control module is separated and made into a separate main control platform 1. It is no longer limited by the narrow space structure inside the rPDU. The structural design becomes more reasonable, which can effectively reduce production difficulty, improve production efficiency, and reduce the defect rate.

[0070] (8) Reduce debugging difficulty. The new rPDU internal functional modules need to communicate with each other and are independently connected to the main control platform 1. The entire system has only one set of communication protocols, which reduces debugging difficulty and improves production efficiency.

[0071] (9) Reduce costs. A computer room only needs one main control platform 1, which reduces the number of main control modules and significantly reduces material costs. At the same time, factors such as simplified structure, reduced production difficulty, reduced debugging difficulty, improved production efficiency, and reduced power consumption significantly reduce production costs and usage costs, greatly reducing the cost of the entire system life cycle.

[0072] (10) Convenient for the overall layout of the computer room. The entire computer room only needs one network cable to communicate with the host computer, which simplifies the overall layout of the computer room and reduces the difficulty of subsequent maintenance.

[0073] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
