Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of terminal power distribution, and in particular to an intelligent terminal power distribution device with a power distribution capacity management function. Background Art
[0002] In the data center cabinets, IT equipment such as servers and switches are all powered by the terminal power distribution power supply, namely PDU. Traditional PDUs can only provide standard equipment power cord plug-in and stable power supply according to pre-designed and manufactured, without any intelligent detection of voltage and current, timely power supply and other functions. In the current IDC data center operation activities, the number and power of equipment installed in each cabinet are different, and there are situations where they can be moved out and moved in at any time, but the maximum power supply capacity of each cabinet, that is, the maximum power of the cabinet, is fixed and cannot be expanded indefinitely. Therefore, when there are a large number of devices in a cabinet and the power is large, once the power is directly supplied, the power of a single cabinet may be overloaded. If all the devices in a cabinet are switched from the power-off state to the power-on state at the same time, it may also cause instantaneous voltage / current overload, seriously affecting the safe operation of the data center.
[0003] The traditional solution is to add a manual approval process before powering on new equipment or restoring power supply as a whole. Before powering on, the equipment room administrator needs to check and approve the power distribution capacity of the cabinet and the entire equipment room. After confirmation, power is supplied, and the power supply requires closing the switches one by one or inserting the powered PDUs one by one. However, this process is cumbersome to execute. Secondly, if there is no equipment room administrator on site during equipment installation, the installer may directly supply power once the equipment is put on the shelf, or forget to power on the equipment one by one. There is still a risk of power overload caused by excessive power distribution capacity of the above cabinets.
[0004] For this purpose, an intelligent terminal power distribution device with power distribution capacity management function is proposed. Summary of the invention
[0005] The purpose of the present invention is to solve the problems raised in the above-mentioned background technology. The present invention provides an intelligent terminal power distribution device with distribution capacity management function.
[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:
[0007] An intelligent terminal power distribution device with a power distribution capacity management function comprises a shell, a main power inlet is arranged at the end of the shell, the main power inlet is connected from an upper power distribution device, the top cover of the shell is provided with an upper cover, and the top surface of the upper cover is provided with an intelligent meter, a communication module and a branch socket, and then a plurality of branch sockets are branched out, wherein the main power inlet and the branch socket are connected to the intelligent meter, the real-time collected current and voltage data of the main power inlet and the branch socket are all connected to the intelligent meter for centralized processing and display, and the generated power and electric energy values are calculated and displayed on the panel of the intelligent meter, and uploaded to the management platform through the communication module at the same time, the shell has built-in corresponding circuit boards, relays, collectors, power lines and copper busbars, and a UPD is installed in the shell.
[0008] Furthermore, the intelligent terminal power distribution includes the following steps:
[0009] S1: After the PDU is installed on the cabinet, the main circuit is energized, but the branch circuit is open by default, and the branch circuit breaker does not supply power at this time;
[0010] S2: After the IT equipment is installed in the cabinet and the power cord is plugged into the PDU, it is still not powered on. If it needs to be powered on, the corresponding power-on operation must be performed through the WEB management interface, and the power-on sequence of the ports is to be loaded in sequence to avoid instantaneous voltage / current shock caused by simultaneous power-on.
[0011] S3: PDU also has capacity management function. The rated maximum power of the PDU and the percentage of the maximum real-time load allowed to expand the rated maximum power, i.e., the capacity threshold, are input from the WEB end. When the ports of the PDU are powered on successively, the current PDU load capacity is calculated in real time.
[0012] S4: Once the set threshold is exceeded, the subsequent output ports will stop powering on to ensure safety.
[0013] S5: The WEB end can also set some ports of the PDU as special ports, which can be powered on all the time. The regular power-on logic does not affect the port, which can ensure that the port always supplies power to important communication equipment to ensure smooth communication between the administrator and the PDU WEB end.
[0014] Furthermore, the intelligent terminal power distribution device has main and branch metering devices to measure current and voltage in real time and calculate power and electric energy in real time.
[0015] Furthermore, the branch circuit has a relay to realize an on-off state control function.
[0016] Furthermore, the default state of the shunt is open.
[0017] Furthermore, an automatic circuit breaker function can be implemented according to a preset threshold value of the branch.
[0018] Furthermore, the device can set a designated branch to be in a normally powered state.
[0019] Furthermore, the device adopts both Ethernet and RS485 communication modes.
[0020] Furthermore, its communication equipment is a switch and an optical transmission equipment.
[0021] The beneficial effects of the present invention are as follows:
[0022] By utilizing technologies such as power electronics and real-time communication, a terminal power distribution unit (PDU) with capacity detection and remote socket on / off control functions is provided, which is equipped with corresponding intelligent detection and control algorithms to achieve observable and controllable power supply for each device in the cabinet, so as to solve the hidden dangers of accidents caused by power overload caused by random power supply to IT equipment in the cabinet, and improve the stability and reliability of the data center.

[0030] like Figure 1 to Figure 2 As shown, an intelligent terminal power distribution device with a power distribution capacity management function includes a shell 6, and a main power supply line 1 is provided at the end of the shell 6. The main power supply line 1 is connected from the upper power distribution device. The top cover of the shell 6 is provided with an upper cover 5, and the top surface of the upper cover 5 is provided with an intelligent meter 2, a communication module 3 and a branch socket 4, and then a plurality of branch sockets 4 are branched out, wherein the main power supply line 1 and the branch socket 4 are connected to the intelligent meter 2, and the real-time collected current and voltage data of the main power supply line 1 and the branch socket 4 are all connected to the intelligent meter 2 for centralized processing and display, and the power and electric energy values are calculated and displayed on the panel of the intelligent meter 2, and uploaded to the management platform through the communication module 3. The shell 6 has built-in corresponding circuit boards, relays, collectors, power lines and copper busbars, and the UPD is installed in the shell 6.
[0031] More specifically, the intelligent PDU has the functions of main circuit monitoring, branch circuit monitoring and branch circuit on-off control, comes with a web management interface, and has two network interfaces: Ethernet and RS485. Each PDU can be directly connected to the switch through its own Ethernet port, or multiple PDUs can be connected in series through the RS485 interface and then connected to the switch through the network interface of the first PDU, and communicate with the background management software. It uses power electronics, real-time communication and other technologies, and provides a terminal power distribution unit (PDU) with capacity detection and remote socket on-off control functions, equipped with corresponding intelligent detection and control algorithms, to achieve observable and controllable power supply for each device in the cabinet, so as to solve the hidden dangers of accidents caused by power overload caused by arbitrary power supply to IT equipment in the cabinet, and improve the stability and reliability of the data center.
[0032] Intelligent terminal power distribution includes the following steps:
[0033] S1: After the PDU is installed on the cabinet, the main circuit is energized, but the branch circuit is open by default, and the branch circuit breaker does not supply power at this time;
[0034] S2: After the IT equipment is installed in the cabinet and the power cord is plugged into the PDU, it is still not powered on. If it needs to be powered on, the corresponding power-on operation must be performed through the WEB management interface, and the power-on sequence of the ports is to be loaded in sequence to avoid instantaneous voltage / current shock caused by simultaneous power-on.
[0035] S3: PDU also has capacity management function. The rated maximum power of the PDU and the percentage of the maximum real-time load allowed to expand the rated maximum power, i.e., the capacity threshold, are input from the WEB end. When the ports of the PDU are powered on successively, the current PDU load capacity is calculated in real time.
[0036] S4: Once the set threshold is exceeded, the subsequent output ports will stop powering on to ensure safety.
[0037] S5: The WEB end can also set some ports of the PDU as special ports, which can be powered on all the time. The regular power-on logic does not affect the port, which can ensure that the port always supplies power to important communication equipment to ensure smooth communication between the administrator and the PDU WEB end.
[0038] The present invention optimizes the control logic of each branch relay of the traditional intelligent PDU with branch on-off control function, adds a control chip and related circuits, thereby realizing flexible and on-demand control of each branch.
[0039] The traditional intelligent PDU with shunt on-off control uses shunt relays that can only realize two actions, opening and closing, and cannot realize flexible on-demand opening and closing. However, this device not only adds a default setting for the opening and closing state of the shunt relay (shunt state), but also realizes remote control of multiple shunt relays for each PDU. The PDU is also equipped with a collector for each port circuit and the main circuit to collect the real-time current and voltage conditions of each port and the main circuit, and realize the real-time power and electric energy calculation of each port and the main circuit on the core control board. In addition, the core control board of the intelligent PDU also adds threshold settings for voltage / current / power, and associates the threshold with the linkage control function, which can realize automatic power off when the PDU port exceeds a certain threshold after power is turned on, so as to protect the PDU and terminal electrical equipment.
[0040] The intelligent terminal power distribution device has a main circuit and a branch circuit metering device to measure the current and voltage in real time and to calculate the power and electric energy in real time.
[0041] The branch circuit has a relay to realize the on-off state control function.
[0042] The default state of the shunt is open.
[0043] The automatic circuit breaker function can be realized according to the preset threshold value of the branch.
[0044] The device can set a specified branch circuit to a normally energized state.
[0045] The device uses both Ethernet and RS485 communication modes.
[0046] Its communication equipment includes switches and optical transmission equipment.
[0047] To sum up: In view of the shortcomings of the existing technology, the present invention utilizes power electronics, real-time communication and other technologies to provide a terminal power distribution unit (PDU) with capacity detection and remote socket on / off control functions, equipped with corresponding intelligent detection and control algorithms, to achieve observable and controllable power supply for each device in the cabinet, so as to solve the hidden dangers of accidents caused by power overload caused by arbitrary power supply to IT equipment in the cabinet, and improve the stability and reliability of the data center.
