Description
Technical Field
[0001] The utility model relates to the technical field of power distribution, and in particular to a centralized control type rPDU device. Background Art
[0002] rPDU (Remote Power Distribution Unit), also known as network power control system, remote power management system, intelligent PDU, intelligent power distribution system, is a power distribution system that can be remotely controlled and planned, and is mainly used for power supply control of data centers, equipment control centers and weak current distribution network centers at all levels. rPDU is an industrial-grade intelligent power distribution control unit specially designed for IDC, ICP, ISP, enterprise and institution data centers or equipment control centers and their remote base points. It integrates power distribution, isolation, grounding, monitoring and management in the computer room, and can significantly improve the safety of the computer room power supply system.
[0003] The most basic function of rPDU is similar to that of a power socket, that is, it can supply power to the equipment, and at the same time has powerful functions such as connection, query, monitoring, filing, and intelligent management. It can be used for electrical equipment that originally obtains current through sockets, terminal blocks, and terminal posts.
[0004] The rPDU currently on the market is generally composed of a display main control module, a power module, and a branch module. The modules are connected via RS485 bus / CAN bus. The principle is as follows Figure 1 shown.
[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 module, responsible for on-site information transmission through the human-machine interface and remote information transmission through the network; responsible for receiving on-site instructions and remote instructions, and according to the instructions, controlling the branch module to manage the output bit.
[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; it is responsible for 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 responsible for receiving the instructions from the main control module and managing the output bit according to the instructions.
[0008] In the current design, the rPDU consists of 1 main control module, 1 power module, and 1 to 4 branch modules. The branch modules are located below or on the side of the socket. One branch module can detect and control multiple sockets. The current rPDU structure is as follows: Figure 2 shown.
[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 slow control response: Existing rPDU generally uses RS485 communication, which has an extremely slow communication speed. From the time the host computer sends a command to the time the control response is completed, the theoretical response time exceeds 2s, which is not conducive to instant 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. The accumulated 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. The heat dissipation pressure is very high, and the local temperature may even be too high to damage the rPDU.
[0015] (6) 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. Strong and weak current lines, and strong and signal lines are paralleled over a large span, which are prone to mutual interference and have a high possibility of interference.
[0016] (7) Complex structure, high difficulty in production, and high failure rate: The internal space of the rDPU is very narrow, and there is a serious space limitation. A large number of functional modules need to be integrated in the narrow and severely limited space, which inevitably leads to a complex structure; a complex structure inevitably leads to great difficulty in production; and a high difficulty in production inevitably leads to a low pass rate and a high failure rate;
[0017] (8) Complex production and debugging: In the existing design, there are three sets of protocols running simultaneously inside the rPDU, and the debugging process is complicated, which further increases the difficulty of production and reduces the yield rate;
[0018] (9) High cost: The main control module is expensive, complex in structure, difficult to produce, complex in debugging, and high in power consumption, resulting in a series of high costs such as material cost, production cost, debugging cost, after-sales cost, and use cost;
[0019] (10) 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 make the overall layout of the computer room messy, increase the difficulty of the computer room layout, and also increase the difficulty of subsequent maintenance.

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0039] like Figures 3 to 6 As shown, a centralized control type rPDU device of the utility model 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.
[0040] This device separates the original rPDU main control module, and replaces the original main control module with a unified main control platform 1 to control the rPDU, and establishes a wireless communication connection with each power socket module 3, and directly monitors the specific situation of each power socket module 3 through wireless communication, and the data does not need to be converted multiple times, with fast speed and sensitive response. In addition, the control of a power module of the original rPDU is dispersed to each power socket module 3, and a small power module 4 is configured to realize independent power supply control of each power socket module 3, and the power modules are dispersed to different areas, the heat source is dispersed, and the heat dissipation pressure is reduced, solving the problem of local over-temperature damaging the rPDU.
[0041] like Figure 5 As shown, 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 with 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 that the socket output position 7 and the small power module 4 are in a powered-on state or disconnected state; 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.
[0042] 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.
[0043] 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 terminal and uploading the monitoring data to the main control platform 1 through the socket wireless communication module 5 .
[0044] The rPDU component 2 also includes a power plug 8, and each small power module 4 of each power socket module 3 is individually connected to the power plug 8, and the power plug 8 is connected to the mains power supply. Each rPDU component 2 is connected to the mains through a power plug 8, and each small power module 4 is powered separately, so that the overall power module of the existing rPDU is dispersed, and each power socket module 3 is powered separately. There is no weak current connection between the power socket modules 3 and the power socket modules 3, which solves the problem of large-span parallel operation between strong and weak currents, which is easy to cause interference.
[0045] like Figure 3 and Figure 4 As shown, the main control platform 1 is a control device independent of the rPDU component 2, each rPDU component 2 is an independent socket device, and the main control platform 1 connects and controls at least one rPDU component 2 through wireless communication. After the improvement of this device, only one main control platform 1 is needed to realize the control of multiple rPDU components 2 through wireless communication, so that the main control module on the existing rPDU component 2 is independent, and more space is released for installing the socket output position 7 to better meet the socket position requirements. A single main control platform 1 controls multiple rPDU components 2, and the average power consumption of each rPDU component 2 is reduced.
[0046] At least one power socket module 3 is installed on each rPDU component 2, and the main control platform 1 independently establishes wireless communication with the power socket module 3 of each rPDU component 2. Each power socket module 3 on the rPDU component 2 is an independent module, and each power socket module 3 can independently realize information interaction with the main control platform 1, so that a certain power socket module 3 can be specifically controlled by operating the main control platform 1, and the control method is more flexible and targeted, which solves the problem that all power socket modules 3 on the existing rPDU components can only be uniformly controlled by their main control modules.
[0047] like Figure 6 As shown, the main control platform 1 includes a central processing unit 11, which is connected to a main control wireless communication module 12. The central processing unit 11 receives data fed back by 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.
[0048] The central processor 11, as the core of the entire main control platform 1, is responsible for processing the received data, and sends instructions to the power socket modules 3 on different rPDU components 2 according to the user's control requirements or set control requirements, controls the on and off of different power socket modules 3, and the output of the small power module 4, and monitors the branch module 6 and the small power module 4 in real time, and feeds back the monitoring situation in real time. The central processor 11 is connected to the main control wireless communication module 12 through the connector inside the main control platform 1, and receives the 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 processor 11 also connects 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 and control instructions. At the same time, the situation of each power socket module 3 in the rPDU component 2 is presented on the display screen in real time.
[0049] The centralized control type rPDU device also includes a host computer, and the main control platform 1 is also provided with a network conversion module and a network interface. The central processor 11 is connected to the host computer through the network conversion module, and then through the switch and the network interface. The main control platform 1 is connected to the host computer through a network cable, and sends the received data to the host computer, and receives the command data sent by the host computer. The entire device only needs one main control platform 1 to connect to the host computer, which solves the problem that the existing rPDU requires multiple main control modules to be connected to the host computer through network cables, which causes the layout of the computer room to be complicated.
[0050] The main control platform 1 also includes a power conversion module 13, and the main control platform 1 is connected to the mains power supply through the power conversion module 13. The main control platform 1 is independently connected to the mains power supply and does not share power with the rPDU component 2, which can reduce the occupation of power supply resources of the rPDU component 2.
[0051] The main control platform 1 also includes an RS485 communication module and an RJ45 interface, and the central processing unit 11 connects to external devices and sensors through the RS485 communication module and the RJ45 interface to realize 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 realize signal input and output.
[0052] The working mode of this centralized control type rPDU device is:
[0053] 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.
[0054] The main control platform 1 has two working modes: networking mode and normal working mode.
[0055] After the system hardware is built, the system enters the normal working mode by default. You can force the main control platform 1 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 there is a reset and restart operation, the system automatically enters the normal working mode.
[0056] In the networking mode, the main control platform 1 inquires and obtains the MAC addresses of all power socket modules 3 by broadcasting, and records and saves them in the address database.
[0057] In normal working mode, the main control platform 1 sends query instructions and control instructions with MAC address information one by one in sequence through broadcasting according to the MAC address information stored in the address library, and processes and analyzes the returned information; after all the stored MAC addresses in the address library are queried and controlled, the next round of query and control will continue for all MAC addresses, and the query and control will continue in this way. After receiving the broadcast information, the power socket module 3 first determines whether the MAC address in the broadcast information is the MAC address of the power socket module 3 itself. If it is its own MAC address, it will upload data or perform control operations according to the instruction information. If it is not its own MAC address, it will not respond.
[0058] This centralized control type rPDU device has the following advantages through design innovation:
[0059] (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, thus doubling the resource utilization.
[0060] (2) Release valuable socket resources. The main control module and the power module occupy about 7 sockets. The main control module is separated, and the power module is replaced by a small power module 4 and combined with the socket & branch module 6 into a socket & branch & small power combination module, which can release 7 sockets to better meet the socket demand.
[0061] (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.
[0062] (4) Reduce overall power consumption. A single master control platform 1 controls multiple rPDUs, and the average power consumption of each rPDU is reduced.
[0063] (5) Effectively solve the problem of local high temperature. Distribute the power modules to different areas, disperse the heat source, reduce the heat dissipation pressure, and solve the problem of local high temperature damaging the rPDU.
[0064] (6) Solve the problem of large-span parallel connection between strong and weak electricity, which is prone to interference. The power supply module is 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 separately, and there is no weak current connection between the combination modules, which solves the problem of large-span parallel connection between strong and weak electricity, which is prone to interference.
[0065] (7) The structure is relatively simple, which reduces the difficulty of production. 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 the difficulty of production, improve production efficiency, and reduce the defect rate.
[0066] (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 the difficulty of debugging and improves production efficiency.
[0067] (9) Reduce costs. A computer room only needs one main control platform 1, the number of main control modules is reduced, and the material cost is greatly reduced. At the same time, the simplified structure, reduced production difficulty, reduced debugging difficulty, improved production efficiency, and reduced power consumption greatly reduce production costs and usage costs, greatly reducing the cost of the entire system life cycle.
[0068] (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. The overall layout of the computer room is simple, and the difficulty of subsequent maintenance is also reduced.
[0069] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
