DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present invention will be further described below in conjunction with the embodiments.

[0032] refer to Figure 1-Figure 6 The present invention provides an expandable and modular computing center power supply and communication system, which aims to improve the deficiencies in the existing computing center design such as flexibility, scalability and maintenance efficiency, optimizes the power distribution and heat dissipation mode, has the advantages of high-density deployment and flexible expansion, and adapts to the needs of modern data processing. Traditional computing centers often adopt a centralized power supply and communication layout. This design makes it difficult for the entire system to expand new hardware resources, such as adding additional servers or storage units. In addition, once maintenance or upgrading is required, the operation of the entire system may be affected, resulting in operational interruption and increased maintenance costs. This design lacks flexibility and is not conducive to quickly adapting to changes in technological development and business needs. In addition, the energy efficiency of centralized systems is often low because the power supply and cooling systems must be designed to handle the maximum expected load, which often leads to energy waste in actual operation. The overall system includes a cabinet, an overall bracket, a server inside the cabinet, a power distribution unit (PDU), a switch and other components. At the same time, the module reserves multiple interfaces, supports mainstream communication protocols such as ModbusTCP, MQTT, OPC, etc., and is convenient for access to the corresponding programmable logic controller PLC and human-machine interface (HMI).

[0033] Specifically, the equipment inside the cabinet is arranged along the length of the cabinet to form a reasonable overall layout. The power distribution unit (PDU) is arranged above the cabinet and also arranged along the length of the cabinet to ensure efficient power distribution. The PLC is placed on the top of the PDU close to the power cord to facilitate power management and monitoring. The switch is arranged in a row below the PDU and above the server cabinet to achieve efficient data transmission. The server inside the cabinet is connected to the power distribution unit (PDU) and the switch interface and is located on one side of the main structure to achieve fast data transmission and power supply. As a client, the HMI connects and transmits data with the PLC and PDU so that users can monitor and control the system.

[0034] The present invention also adopts immersion liquid cooling technology. The servers inside the cabinet are arranged in the rack and connected to the electronic control system to effectively reduce the equipment temperature and improve operating efficiency. At the same time, the overall bracket, as a partial connection carrier between the power distribution unit (PDU) and the switch, participates in the integration of data exchange and power supply lines, and optimizes the system structure. To ensure the safety of the system, the power distribution unit (PDU) is equipped with a protection device that can automatically cut off the circuit in the event of severe overload, short circuit or voltage abnormality, and has self-test and current monitoring functions to ensure the stable operation of the system. In addition, the power distribution unit (PDU) is also equipped with a liquid crystal display module that can display parameters such as current and power factor in real time, and monitor the status of the power system.

[0035] refer to Figure 1-Figure 6The present invention includes a cabinet group, which includes two cabinets 6 that are symmetrically fixedly connected. An integral bracket 1 is provided above each cabinet group, and the integral bracket 1 is located at the connection between the two cabinets 6. A plurality of rows of heat dissipation holes are evenly arranged at the top of the integral bracket 1, and an iron protective net is installed on the surface of the heat dissipation holes. A server is installed inside the cabinet 6. A switch 3 is arranged on the integral bracket 1, and the switches 3 are arranged along the connection direction of the two cabinets 6. A plurality of power distribution units 2 are arranged on the integral bracket 1, and the power distribution units 2 include a plurality of parallel PDU communication power supply modules, and each PDU communication power supply module is equipped with two power supply interfaces and two switch interfaces. There is a gap between the bottom wall of the integral bracket 1 and the cabinet 6, and the bottom of the integral bracket 1 A placement rack is provided on the wall, and the switch 3 is placed in the placement rack. A power supply bracket 9 is provided on the integral bracket 1, and a plurality of connection holes are provided on the power supply bracket 9. The power distribution unit 2 is located on the power supply bracket 9. The server is connected to the power supply distribution unit 2 and the switch 3 interfaces one by one. The power distribution unit 2 also includes a liquid crystal display main control module 4, which is used to display electrical parameters. The liquid crystal display main control module 4 is provided with a northbound interface. The power distribution unit 2 also includes a circuit breaker module. A cover plate is hinged on the top of the cabinet 6, and a disassembly and assembly component is provided between the cover plate and the cabinet 6. A plurality of equidistantly arranged wire connection holes 5 are provided on the top wall of the cabinet 6, and a sealing ring is provided on the wire connection hole 5. The wire connection hole 5 is located directly below the integral bracket 1.

[0036] A connection assembly is used for connecting adjacent cabinet groups and connecting power distribution units 2 on different cabinets 6, including a fixing frame 11 fixedly mounted on an integral bracket 1, a movable joint 12 movably inserted on the fixing frame 11, a telescopic line 14 provided on the movable joint 12, a fixed joint 15 provided on the telescopic line 14, the connection assembly also includes a first piston tube 16 fixedly mounted on the fixing frame 11, a first piston rod 17 movably inserted on the first piston tube 16, a return spring 18 movably sleeved on the first piston rod 17, a second piston tube 22 fixedly mounted on the fixing frame 11, a second piston rod 23 movably inserted on the second piston tube 22, the second piston rod 23 and the fixed joint 15 are fixedly connected, A first connecting tube 24 is connected between the first piston tube 16 and the second piston tube 22, an auxiliary airbag 19 is fixed to the end of the first piston rod 17 away from the first piston tube 16, a detection sealing airbag 20 is fixedly installed on the fixed joint 15, a sealing ring 21 is provided on the sealing airbag 20, the sealing airbag 20 and the auxiliary airbag 19 are connected, a connecting line 13 is connected between the power distribution unit 2 and the movable joint 12, a third piston tube 25 is provided on the fixed frame 11, a third piston rod 26 is movably inserted on the third piston tube 25, a clamping piece 27 is provided on the third piston rod 26, and the clamping piece 27 is used to clamp the connecting line 13, and a second connecting tube 28 is connected between the third piston tube 25 and the first piston tube 16;

[0037] The liquid cooling circulation component includes a liquid inlet pipe 7 and a liquid outlet pipe 8 installed in the cabinet 6. The liquid inlet pipes 7 and liquid outlet pipes 8 in adjacent cabinets 6 are connected one by one. A plurality of liquid outlet holes are provided on the liquid inlet pipe 7, and a flow monitor 10 is provided at the liquid outlet hole. The cabinet 6 is a fully enclosed sealing structure, and an immersion cooling liquid is provided in the cabinet 6.

[0038] When expansion is required, one or more additional cabinet groups are connected to one side of the cabinet 6 at the end, specifically, Figure 4 As shown, through the connecting assembly, the two fixing frames 11 are fixedly connected by bolts and nuts, and after the connection is completed, the two fixing joints 15 are connected, and then the power distribution unit 2 on the same cabinet 6 is connected to the movable joint 12. The power distribution unit 2 is externally connected to a connecting line 13, and a plug is provided at the end of the connecting line 13, which is connected to the movable joint 12 by plugging (this is the prior art and will not be elaborated on).

[0039] During the connection of the two fixed joints 15, the two auxiliary airbags 19 will be squeezed, and the gas in the auxiliary airbags 19 will enter the sealing airbag 20. The sealing airbag 20 will expand, so that the connection between the two fixed joints 15 is sealed from the outside, thereby improving the safety of the connection.

[0040] On the other hand, after the two fixed joints 15 are connected, if shaking or vibration inside the device occurs, the two fixed joints 15 may shake, such as Figure 4 As shown, when shaking occurs, according to the direction of shaking, the first piston rod 17 on one side will be pulled to squeeze the first piston rod 17 on the other side, and the squeezed first piston rod 17 will compress the air in the first piston tube 16, and the air in the first piston tube 16 will be pressed into the second piston tube 22, and the second piston rod 23 will extend from the second piston tube 22, so that one of the fixed joints 15 moves toward the other fixed joint 15 to prevent the two from loosening. The space in the first piston tube 16 corresponding to the pulled first piston rod 17 becomes larger, and the air in the corresponding third piston tube 25 is extracted, so that the third piston rod 26 moves into the third piston tube 25, and the corresponding end of the connecting line 13 moves toward the movable joint 12, improving the stability of the connection between the two.

[0041] It is worth noting that both the second piston tube 22 and the third piston tube 25 are provided with limit blocks, whose function is to allow the second piston rod 23 to slide within a certain range so that it has an initial position and cannot move into the second piston tube 22 at the initial position. That is, when shaking, only the fixed joint 15 will be more secure and will not loosen. The same is true for the third piston rod 26, and the direction of movement is controlled differently.

[0042] The inlet pipes 7 and outlet pipes 8 between adjacent cabinets 6 are connected correspondingly, and multiple outlets are provided on the inlet pipes 7, and control valves are provided on the outlets. A flow monitor 10 is provided on each outlet, because the inlet pipes 7 and outlet pipes 8 located in the head end cabinet 6 are externally connected to a circulation pump assembly and a cooling assembly (the cooling means are prior art and will not be described in detail), and the outlet holes on the inlet pipes 7 that are closer to the liquid pump discharge liquid faster. In order to ensure the balance of cooling, the liquid flow rate per unit time of each inlet pipe 7 is detected to control it within a good range, and this range can be obtained according to actual needs and experiments. In this way, the size of the outlet can be controlled by flow monitoring and control valves to ensure that the amount of liquid inflow in each cabinet 6 is similar. It is worth noting that a control valve is also provided on the outlet pipe 8 to ensure the balance of liquid outflow and liquid inflow.

[0043] The scalable modular computing center power supply communication system of the present invention includes multiple power distribution units (PDUs), switches, correspondingly connected program controllers (PLCs), human-machine interfaces (HMIs), and fully enclosed sealed cabinets. Multiple servers are placed inside the cabinets, and these servers are immersed in coolant to achieve efficient heat dissipation.

[0044] In this embodiment, each expandable modular computing center power supply communication system includes a program controller (PLC), and its corresponding human-machine interface (HMI) and a closed sealed cabinet, and twelve PDU communication power supply modules arranged in parallel. Each PDU communication power supply module is equipped with two power supply interfaces and two switch interfaces. The twelve modules are respectively connected to the twenty-four servers in the cabinet. It is worth noting that the number of the above-mentioned PDU communication power supply modules, the number of interfaces and the number of connected servers need to be determined according to actual conditions. The above is an example, and the specific connection method is also the same. Each module acts as a ModbusRTU slave (S l ave) to realize centralized management and control of data. The LCD screen of the PDU acts as a ModbusRTU master (Master). The LCD screen is not only used to display information, but also has the slave function of ModbusRTU or the server function of ModbusTCP, which can realize data forwarding. This data interaction method also supports remote operation using HMI.

[0045] To ensure the efficient operation of the system, the IP addresses of each device are configured with static IP. The communication between HMI and PLC, and between PLC and PDU is based on IP addresses. Therefore, when the IP address of the device needs to be changed, the HMI or PLC program must be updated at the same time to avoid communication failures. According to the ModbusTCP communication address table provided by the PDU manufacturer, a program is written in the PLC to collect the switch status, active power and total power of the PDU, and control the closing and disconnecting functions of the PDU relay. This program design can effectively monitor and manage the power supply of the computing center and improve the operating efficiency and safety of the system.

[0046] During the implementation process, we first designed and manufactured multiple modular units according to the actual needs of the computing center. Each module should include independent power supply, heat dissipation and network equipment to facilitate flexible configuration. Then, the fully enclosed cabinets were assembled according to the design drawings to ensure the sealing and stability of the cabinets, and to reserve enough space to accommodate the servers and cooling systems.

[0047] In terms of power connection, each PDU is connected to the power interface on the top of the cabinet through a standardized power cord to ensure reliable power distribution. The design of the PDU allows multiple modules to be connected in parallel to support the power requirements of high-density servers. The output port of the module is directly connected to the server power interface inside the cabinet to ensure that each server can obtain a stable power supply.

[0048] In terms of data transmission, Ethernet connection is used between HMI, PLC and PDU. HMI acts as a client and exchanges data with PLC through Ethernet, and PLC then communicates with PDU. Specifically, HMI acts as a client and exchanges data with PLC, while PLC acts as a server; for communication between PLC and PDU, PLC also acts as a client and PDU acts as a server. It should be noted that the communication between HMI and PDU is carried out through PLC, and there is no direct data exchange between the two. Connect the power cord and data cable to each device in turn, ensure that the power cord between each server and PDU is firmly connected, and ensure the correct connection of the data cable to achieve efficient data transmission.

[0049] In this scalable and modular computing center power supply communication system, the data transmission process can be divided into multiple stages, from device data collection to data transmission, processing and feedback, each step plays an important role in ensuring the stable operation of the system. The following is a detailed expansion of this data transmission process: Each module (such as PDU, server, switch, etc.) collects its operating parameters such as current, voltage, power, temperature, humidity, load, etc. in real time through sensors or built-in monitoring systems. These data are preliminarily sorted and encoded through the serial communication interface (ModbusRTU) or Ethernet interface (ModbusTCP) and are ready to be sent to the main control system. According to the specific content of data collection, the data is transmitted to the main control device through serial communication (ModbusRTU) or IP network (ModbusTCP). Among them, when using the ModbusRTU protocol, the data is transmitted through the serial interface of the device, which is particularly suitable for data exchange between short-distance and low-bandwidth devices, ensuring stable data transmission even in the case of dense equipment. This method is suitable for scenarios with close distances or concentrated equipment, such as communication between switches and servers. For remote control and large-scale data exchange, ModbusTCP communicates through the network, supports high-bandwidth data transmission and remote monitoring. ModbusTCP takes advantage of the network to improve data transmission rate and remote operation capabilities, and adapts to the needs of large-scale computing centers.

[0050] After receiving the data from each module, the main control device (such as PLC or HMI) performs data analysis, processing and storage. PLC makes real-time judgments based on the set logic and controls the device status. If any abnormality is found (for example, power overload or server temperature is too high), it will immediately trigger an alarm or automatically adjust the control strategy. At this time, maintenance personnel can remotely diagnose the problem based on data feedback and take timely measures to avoid the spread of system failures, so as to provide early warning and fault diagnosis for related problems. Through data transmission, administrators can monitor the operating status of the computing center in real time by remotely accessing the HMI interface. Managers can: 1. Adjust configuration: Remotely adjust the server's power supply, the working status of the cooling system, or perform load balancing based on real-time data. 2. Troubleshooting: Remotely view data and logs, locate equipment problems, and perform remote diagnosis and repair operations.

[0051] The operating principle of the modular computing center power supply communication system of the present invention is based on efficient power management and intelligent data communication. The PDU in the system is responsible for distributing power to each server. The communication power supply module inside each PDU ensures efficient distribution of power by monitoring current and power factor. The PDU is equipped with a relay protection device, which can automatically cut off the circuit to ensure the safety of the system when a serious overload, short circuit or voltage abnormality occurs. Through the ModbusRTU protocol, centralized data management is achieved between each server and the PDU. Each module acts as a slave station (Sl ave) and transmits status information to the master station (Master) in real time. The LCD display can display parameters such as current and power factor in real time, and users can remotely monitor and control through the HMI.

[0052] As the core control unit of the system, PLC is responsible for coordinating the communication between various devices. PLC regularly collects the status information of PDU and controls it according to the set logic, such as adjusting the on / off status of the power supply and monitoring power consumption. This intelligent management method not only improves the operating efficiency of the system, but also reduces the operation and maintenance costs. Since the server is immersed in the coolant, the system can achieve efficient heat dissipation. The coolant continuously removes heat through the circulation system, ensuring that the equipment operates at the optimal temperature, further improving the stability and safety of the system.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
