Detailed Description

Embodiments of the present application will be described in detail below with reference to the accompanying drawings in conjunction with the embodiments.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

It should be noted that, modern data centers (corresponding to the data centers in the above embodiments) all need to perform U-bit (or referred to as U-space) management on deployed servers and cabinets to realize the following purposes 1-5:

Application 1: space planning is achieved. Through U-bit management, the space of equipment in a machine room can be effectively planned and managed. An administrator can plan U-bit allocation of each rack in advance, so that orderly and orderly installation of equipment is ensured, and maintenance and management are facilitated.

Application 2: realizing heat dissipation and ventilation. Ensuring sufficient space between the server and other devices facilitates good heat dissipation and ventilation. Reasonable U-bit management can prevent too dense among the equipment, leads to the heat dissipation not enough, influences equipment performance and life-span.

And 3: and the maintenance and the replacement are convenient. U-bit management may help administrators quickly locate and access target devices when maintenance or replacement of the devices is required. This makes the maintenance work more efficient and reduces downtime.

Application 4: and realizing cable management. By U-bit management, cables between devices can be managed more easily. This includes power lines, network lines, etc. Clear cable management helps to reduce the risk of failure and simplifies tracking and tuning of the cable.

Use 5: and resource planning is facilitated. When installing equipment in the U-position, an administrator can plan resources better, ensure that the rack space is fully utilized, and leave a certain margin to adapt to future expansion.

Further, to achieve the above U-bit management purposes, a typical data center U-bit management architecture needs to perform the following: 1) A comprehensive U-bit numbering and identification system is established to ensure that each U bit has a unique identifier. 2) A detailed rack layout is created that identifies the U-bit allocation and equipment information on each rack. This drawing may provide useful information in terms of the physical space and power distribution of the data center. 3) Effective cable management strategies are implemented, including orderly placement of transverse and longitudinal cables, to reduce clutter and improve maintainability. The use of labels and color coding allows the cable to be easily identified. 4) Physical security of the U-bits is emphasized, ensuring that only authorized personnel can access the racks and equipment. This may involve security measures such as locking the housing, using the monitoring camera, etc. 5) Remote monitoring and automation tools are incorporated so that an administrator can remotely monitor device status, implement changes, and perform maintenance operations. This helps to reduce human intervention and increase response speed. In the related art, a typical U-bit management architecture of a data center is shown in fig. 1, and a device diagram corresponding to the typical U-bit management architecture of the data center is shown in fig. 2. As can be seen from fig. 1 and fig. 2, in order to implement U-bit management, a typical data center needs to add a U-bit management module, a U-bit gateway, a U-bit asset association tag (equivalent to the U-bit asset tag in fig. 2), an expansion module, a U-bit management specialized switch device, and other devices in its architecture. The expansion module, the U-bit asset tag, etc. need to be set for each cabinet, so that a great amount of devices need to be additionally added in a typical U-bit management architecture of the data center, and the construction cost is high.

To solve the above-mentioned problems, an embodiment of the present application provides an identifier allocation system, and fig. 3 is a schematic diagram of an identifier allocation system according to an embodiment of the present application, where the identifier allocation system includes the following:

The device information of the target device includes, but is not limited to, power supply information, power consumption information, and the like of the target device.

Optionally, the target device includes, but is not limited to, a server, a switch, a storage device, and the like. Servers, switches, storage devices, etc. may all be disposed in at least one rack unit. Optionally, each power supply supplies power to a target device to which the power supply is uniquely connected and transmits an identifier to which the target device is assigned.

Optionally, the power line communication circuit includes: a coupler connected in series with an ac power line for decoupling a power signal received from the ac power line into a low frequency power supply signal and a first high frequency communication signal, wherein the first high frequency communication signal carries the identifier, the ac power line being for transmitting the power signal; and the first microprocessor is connected in series with the coupler and is used for decoding the first high-frequency communication signal to obtain the identifier and transmitting the identifier to the target equipment.

Optionally, the first microprocessor is further configured to encode data received from the target device into a second high frequency communication signal.

Further, the coupler is further configured to transmit a second high frequency communication signal received from the first microprocessor to the ac power line. Wherein the ac power line is further configured to transmit the second high frequency communication signal.

It will be appreciated that the coupling of signals may be achieved when the first high frequency communication signal or the second high frequency communication signal is input into an ac mains. For example, a first high frequency communication signal is input into an ac power line, coupled with a low frequency power supply signal in the ac power line, to obtain a power signal.

Optionally, the power supply in the embodiment of the present application is connected in series between the ac power line and the target device, and further the power line communication circuit is also connected in series between the ac power line and the target device. Further, the connection mode of the coupler and the first microprocessor included in the power line communication circuit in the identifier distribution system is as follows: the coupler is respectively connected with the alternating current power line and the first microprocessor in series, and the first microprocessor is respectively connected with the coupler and the target equipment in series.

Therefore, the embodiment of the application realizes the purposes of simultaneously supplying power to the target equipment and transmitting the allocated identifier of the target equipment through the coupler and the first microprocessor; the problem of cost consumption caused by the fact that extra equipment is required to be configured for identifier transmission for the data center in the related technology is avoided, and meanwhile, the physical space of the data center architecture is saved.

Optionally, the coupler includes: a coupling transformer for transmitting the received power signal to an active band pass filter bank or for transmitting the second high frequency communication signal received from the active band pass filter bank to the ac power line; the active band-pass filter bank is connected in series with the coupling transformer and is used for separating the low-frequency power supply signal and the first high-frequency communication signal from the power signal or amplifying the second high-frequency communication signal.

Further, the coupler further includes: and a first port of the first capacitor is connected in series to the alternating current power transmission line, and a second port of the first capacitor is connected in series to the input port of the coupling transformer.

Alternatively, the first high-frequency communication signal may also carry other transmission information that needs to be transmitted to the target device, which is not limited in the embodiment of the present application.

Alternatively, the coupling transformer may also enable the separation of the high frequency communication signal and the low frequency supply signal from the power signal. In particular, the coupling transformer can separate the high frequency communication signal and the low frequency power supply signal by designing an appropriate circuit structure. Typically, the core and windings of a coupling transformer will have different frequency response characteristics, the core will have a better response to high frequency signals and a relatively weaker response to low frequency signals, while the windings may have opposite characteristics. By reasonably designing parameters of the magnetic core and the windings, high-frequency signals can be transmitted to one winding more, and low-frequency signals can be transmitted to the other winding more; that is, in this case, only at least two windings need to be present on the secondary side of the coupling transformer. In addition, a filter can be added in the coupling transformer to further separate the high-frequency signal and the low-frequency signal, so that the filtered high-frequency signal and the filtered low-frequency signal are obtained at the output end, and the separation of the signals is realized.

In general, the coupling transformer can effectively separate high frequency signals and low frequency signals by designing proper circuit structures and parameters, introducing filters, and the like.

Therefore, the embodiment of the application specifically realizes the separation of the power signals and/or the amplification processing of the first high-frequency communication signals through the coupling transformer and the active band-pass filter bank in the coupler, so that the power supply source has the functions of supplying power through the low-frequency power signals and transmitting the high-frequency communication signals.

Both active bandpass filters are composed of a low-pass filter and a high-pass filter connected in series. The cut-off frequency of the high-pass filter must be smaller than the cut-off frequency of the low-pass filter.

According to the application, the high-frequency communication signals can be transmitted in a bidirectional manner between the target equipment and the alternating-current power transmission line through the input active band-pass filter and the output active band-pass filter, so that a communication signal transmission scheme is provided for the target equipment connected to the alternating-current power transmission line and a preset management platform.

It will be appreciated that the second capacitor and the third capacitor provide dc isolation for the input active bandpass filter and the output active bandpass filter, respectively, and act as voltage stabilizing filters. And the voltage stabilization and filtering effects of the active band-pass filter bank are guaranteed through the second capacitor and the third capacitor, so that the normal operation of the active band-pass filter bank is guaranteed.

From the viewpoint of occupying frequency bandwidth, it can be classified into a narrowband PLC (NB-PLC) and a wideband PLC (BB-PLC). Wherein, carrier frequency range of narrowband PLC: different countries and different regions, the U.S. is 50-450 kHz, the Europe is 3-148.5 kHz (below 95 kHz for accessing Access communication and above 95 kHz for indoor In-house communication), and the Chinese is 40-500 kHz.

Carrier frequency range of wideband PLC: 4-20 MHz (HomePlug Specification v 1.0) in the united states, mainly used indoors; europe is 1.6-10 MHz (Access) and 10-30 MHz (In-House); china has no broadband PLC standard. From the viewpoint of the communication rate to be realized, it can be classified into a low-speed PLC (LS-PLC) and a high-speed PLC (HS-PLC), and the line speed is generally 2 Mb/s. In general, NB-PLC is equivalent to LS-PLC and BB-PLC is equivalent to HS-PLC. Another classification method is application-specific.

The application adopts the carrier frequency range of the domestic optimum narrow-band PLC of 40-500 kHz, and needs to be lower than 0.15MHz (150 KHz) to avoid the problems of conduction and radiation disturbance and instrument test errors, so the embodiment of the application takes 100KHz as the communication transmission rate. Because the working voltage of many singlechips is 5V, because most chips are 5V TTL level, therefore decide to be 5V working jolt.

Based on the above, the embodiment of the application combines the 220V/60Hz low-frequency power signal and the high-frequency communication signal of 5V/100KHz through the coupler and then transmits the signals. The coupling of 220V/60Hz low frequency power (equivalent to the low frequency power supply signal in the above embodiment) and the high frequency communication signal 5V/100KHz is shown in FIG. 7. On the contrary, the receiving end separates the high-frequency communication signal from the low-frequency power signal through the coupler, so that the required data transmission can be obtained. The PLC power signal is decoupled into a 220V/60Hz low frequency power signal and a high frequency communication signal 5V/100KHz as shown in FIG. 8.

Step S63: the PLC module (corresponding to the power line communication circuit in the above embodiment) and the server power supply are combined into a power supply with the power line communication function.

The power supply has a power line communication function by combining a PLC MCU (corresponding to the first microprocessor in the above embodiment) with a primary side MCU (corresponding to the second microprocessor in the above embodiment). The power supply structure with the power line communication function is shown in fig. 9. After the power supply with the power line communication function is connected with the target equipment and the alternating current power line, a corresponding architecture diagram is shown in fig. 10.

Further, the construction process of the PLC module includes:

step S631: and selecting the type of the PLC MCU.

The power line carrier MCU is a SOC (System on Chip) carrier communication function, and the main parameters are carrier center frequency, frequency band and modulation mode, and parameter requirements on the MCU part. When selecting an MCU for power line communication, certain factors need to be considered to ensure that the final selected MCU can accommodate the application requirements. The following are key factors that may be considered in the selection of alternative embodiments of the present application, including: 1) Communication standards and protocols: the standards and protocols required for power line communication systems are known. Common power line communication standards include ITU G.9903 (G3-PLC) and HomePlug, among others. 2) Frequency range: it is ensured that the power line communication module of the MCU supports 100KHz with a frequency range of recommended values on which to plan to operate. 3) Noise and interference resistance: since noise and interference may exist in the power line communication environment, the MCU having good resistance is selected. 4) Data rate: the MCU supporting a sufficient data rate is selected according to the application requirements. Different power line communication standards support different rates. 5) Integration: some MCUs may integrate power line communication modules, which helps to simplify the design and reduce system costs. 6) Power consumption: if the application has stringent requirements on power consumption (e.g., battery powered devices), a lower power MCU is selected. 7) Peripheral interface: ensuring that the MCU has sufficient peripheral interfaces to connect to sensors, actuators or other external devices. 8) Programmability: the MCU is selected to be easily programmable so as to flexibly adapt to different communication requirements and algorithms. 9) Safety: according to the requirements of the application on the safety, the MCU is ensured to support necessary safety characteristics and protocols.

Step S632: and (5) selecting and constructing the PLC Coupler.

The main function of the PLC Coupler is the connection between the power line communication function and the power line, and is responsible for receiving and transmitting signals and isolating the influence of high voltage on the PLC MCU interface. The PLC Coupler mainly includes: a high voltage capacitor (HV Cap), a coupling transformer (Coupling Transformer) 3, and an active Band pass filter (OPA Band-PASS FILTER, which is called OBPF for short). A PLC Coupler architecture diagram is shown in fig. 11.

The high-voltage capacitor (HV Cap) functions and selects a Y capacitor similar to that in the electromagnetic interference filter (EMI FILTER) and is connected across the two lines of the power line and the ground, respectively. The main purpose is to isolate high frequency switching noise, release the noise to the other side through the Y capacitor, avoid radiating out through the input line, and reduce noise interference. In these applications it may be necessary to withstand large stresses such as high voltages and the like, and therefore it is necessary to use capacitors that have been certified by all relevant standards. The Y capacitance is classified into Y1, Y2, Y3 and Y4 according to the insulation level. Wherein, Y1 high voltage resistance is more than 8kV, Y2 high voltage resistance is more than 5kV, Y3 high voltage resistance n/a, Y4 high voltage resistance is more than 2.5kV. The capacitance value is typically in the PF level, and GJB151 specifies that the capacitance of the Y capacitor should be no greater than 0.1uF.

It should be noted that the coupling transformer is a type 1:1, a high-frequency isolation transformer, and a circuit diagram of a PLC high-voltage capacitor and a coupling transformer is shown in the following figure 12. The isolation transformer is used for preventing accidental contact with charged bodies at the same time, and the isolation of the transformer is used for isolating respective currents of primary and secondary winding coils. The primary side winding and the secondary side winding are provided with special transformers with higher insulation strength to isolate different potentials and inhibit common mode interference. The transformation ratio of an isolation transformer is typically 1:1. the isolating transformer belongs to a safe power supply, is generally used for machine maintenance, and has the functions of protection, lightning protection and filtering. The principle of the isolation transformer is the same as that of a common transformer. All utilize the principle of electromagnetic induction. Isolation transformers are generally (but not entirely) referred to as 1:1. Since the secondary is not connected to ground. And no potential difference exists between any secondary wire and the ground, so that the use is safe. Are commonly used as maintenance power supplies. The power supply for the control transformer and the valve equipment is also an isolation transformer. Such as valve amplifiers, valve radios and oscilloscopes, and lathe control transformers are isolation transformers.

It should be noted that, the active band-pass filter in the alternative embodiment of the present application includes: a PLC Input OPA active bandpass filter (equivalent to the Input active bandpass filter in the above embodiment), a PLC Output OPA active bandpass filter (equivalent to the Output active bandpass filter in the above embodiment). The OPA is an operational amplifier (Operational Amplifier, simply referred to as OPA).

The PLC Input OPA active band-pass filter aims at separating the communication signals of 5V/100KHz of the low frequency and the high frequency of the 60Hz of the PLC and amplifying the signals. A schematic of a PLC 100KHz input active bandpass filter is shown in fig. 13. The bandpass waveforms are shown in fig. 14 and 15. The bandpass filter has a passband between f _L～f_H. It allows the frequency components of the signal above f _L and below f _H to pass unattenuated while the other components are attenuated. In practice, the low-pass filter and the high-pass filter are connected in series to form a band-pass filter, and it should be noted here that the cut-off frequency of the high-pass filter must be smaller than the cut-off frequency of the low-pass filter, i.e. f _H<f_L, otherwise the newly formed filter becomes a full-frequency filter.

Optionally, the design method of the 100KHz input active band-pass filter of the PLC comprises the following steps:

1) The center frequency fc=100 KHz has been determined and the center frequency formula The design can be set to c1=c2=c, r3=r4=r, and the formula can be simplified by redesigning；

2) To simplify the design, the signal gain a=2 is determined and set to r1=r2=r, and then the signal gain is a=1+r/r=2 according to the signal gain formula a=1+r1/R2.

3) Assuming r1=r2=r3=r4=10k, then c=1/(2pi×100k×10k) =15.9 nF, c1=c2=15.9 nF can be obtained.

Further, the PLC Output OPA Output signal amplifying stage (corresponding to the Output active band-pass filter in the above embodiment) is commonly used in analog circuits (such as sound, temperature, speed, pressure, waveform). The amplifier is a device for converting weak signals into larger signals, and can be designed to be voltage amplification, signal amplification and power amplification. In an alternative embodiment of the present application, the output signal of the PLC MCU (corresponding to the second high frequency communication signal in the above embodiment) is amplified, and the 5V/100KHz signal is output to the ac power line through the coupling transformer.

The reason for the two-stage OPA (Operational Amplifier ) design is mainly as follows: 1) Gain adjustment: the two-stage OPA design may provide more flexible gain adjustment. The first stage OPA may provide an initial gain while the second stage OPA may further adjust the overall gain. This allows the designer to adjust the amplification of the amplifier to the specific application requirements. 2) Bandwidth control: the first stage OPA is typically used to increase bandwidth, while the second stage OPA is used for further fine tuning. This design allows the system to better accommodate signals of different frequencies and provides higher bandwidth when needed. 3) Stability: the two-stage OPA design helps to improve the stability of the system. The first stage OPA may provide sufficient gain while the second stage OPA may ensure stability through a feedback loop, reducing possible oscillations and distortion. 4) Noise performance: the two-stage design may optimize noise performance at different levels. The first stage OPA may reduce input noise in the low frequency range, while the second stage OPA may further process high frequency noise to improve overall signal-to-noise ratio. 5) Amplifier gain design total gain Atotal =a1 x A2, the design can be set to r5=r6=r7=r. Wherein a1=1, as shown in fig. 16; a2 =r5/R6, as shown in fig. 17. Therefore, at this time, the signal gain is a2=1+r/r=2, atotal =a1 x A2 =1x2=2, and r5=r6=r7=10k can be uniformly designed. Alternatively, a PLC 100KHz output active band pass filter is shown in FIG. 18.

Step S633: and the power supply primary side MCU and integration.

The PLC module and the primary side MCU of the power supply are combined into a power supply with a power line communication function. Specifically, the PLC MCU is connected to the primary side MCU of the power supply through a universal asynchronous transceiver, UART in the MCU is connected to General-purpose input/output pin combination (GPIO) of the MCU, wherein UART universal asynchronous transceiver is a type of asynchronous transceiver, which is a part of computer hardware, and transmits data through serial communication.

It should be noted that UART is commonly used in connection with other communication interfaces (e.g., EIA RS-232). The embodiments are embodied as stand-alone modular chips or as internal peripheral devices (peripheral) in a microprocessor. The standard signal amplitude conversion chip is matched with a standard signal amplitude conversion chip of RS-232C standard, such as MAX232, and is used as an interface for connecting an external device. The product of adding a synchronous serial signal conversion circuit to UART is called USART (Universal Synchronous Asynchronous RECEIVER TRANSMITTER). The architecture of the power control panel of the PLC PSU obtained by combining the PLC module with the MCU on the primary side of the power supply is shown in fig. 19, and the combined server power supply has the power line communication function.

Furthermore, the management of the U-bit ID of the target device can be realized through the power supply. Specifically, in the case where the target device is a server, after the server BMC receives the U-bit ID through the power supply (corresponding to the identifier transmitted to the target device through the power supply in the above-described embodiment), the server BMC is allowed to manage the U-bit ID.

IT should be noted that, the U-level positioning, also called U-level (level) asset management, is simply to accurately position the IT equipment in the cabinet of the data center and manage the space resources. At present, the U-position commodity-connected product mainly based on the RFID technology can solve the problems of real-time checking, positioning, online inquiry, U-position utilization rate and the like of the server asset. The U-bit asset management completely solves the defects of the RFID technology in the application scene of the U-bit asset management of the machine room while inheriting the advantages of the RFID tag, and has the characteristics of high reliability, high accuracy, accurate positioning and maintenance free. The machine room U-level positioning goes through 3 stages: first generation technology: the contact type electronic tag, the integrated circuit card is the contact type ID/IC card; second generation technology: a non-contact RFID electronic tag; third generation technology: passive active RFID. Alternative embodiments of the present application provide fourth generation techniques: the server BMC is used to write U-bit ID management to the server power supply.

Specifically, the server BMC performs the U-bit ID management in two parts: part one, PSU expands in the position of FRU EEPROM; and in the second part, the server BMC writes the U-bit ID into the server power supply.

Part one, PSU, expands at the location of the FRU EEPROM.

A field replaceable Unit (FIELD REPLACE Unit, abbreviated as FRU). Typically some replaceable components used on a server (i.e., server). Such as a motherboard, power supply, fan, etc., can be quickly replaced directly if it is a FRU. In a typical server product, information (such as a factory or a product number) of the FRU is burned into a nonvolatile memory (such as an EEPROM or an SPI flash), and some companies refer to the information as VPD (Vital product data, important product data) and some directly refer to the FRU data. The application can obtain the information of manufacturer, product number, etc. of the element by reading FRU data. The length and offset of FRU data will vary with the content, which is composed of the six areas below, and other areas other than the Common Header may be unnecessary.

The six regions include: 1) A Common Header, which is a field that must exist to define the offset of other areas; 2) Internal Use Area the memory is reserved for the firmware to be used as a non-volatile memory; 3) Chassis Info Area the related information for recording the chasis, only one area can be provided on the system; 4) Board Info, such as date of clapping, board factories, S/N number, etc.; 5) Product Info Area: this area would be present if the FRU itself were a product; 6) MultiRecord Info Area MultiRecord information area provides a mechanism to extend the FRU information specification to cover new information types without affecting the existing area definition.

Further, as shown in fig. 20, the PSU FRU instruction table in the related art is provided with an instruction 9Fh below the instruction 9Eh, so that the BMC writes the U bit ID into the MCU on the secondary side of the server power supply. The content of the new instruction 9Fh includes:

Command ID: 9Fh；

Command Name:MFR_U_ID；

SMBus Transaction Type:Write Block；

# of Data Bytes ( Decimal) : 15；

Format :ASCII；

Power On Default Value : n/a；

Based on the newly added instruction 9Fh, the whole U-bit ID word string is 1 number of 15 codes.

For example: write 0Fh,36h,58h,58h,58h,58h,30h,31h,30h,31 h,38h,33h,36h,5Ah,42h,30h = "6XXXX0101E36ZB0".

And in the second part, the server BMC writes the U-bit ID into the server power supply.

The Server system needs to read and write various parameters from and to the Server power supply (Server PSU) at any time in order to perform power management and system optimization. The read contents can be classified into voltage parameters, current parameters, temperature parameters, power parameters, fan rotation speed, etc. The Server uses BMC to access the Server power through I2C Bus (hardware layer), uses PMBus1.2 specification through IPMI instruction set (software layer), and obtains each reading value from Server PSU. The I2C path has a serial component communication architecture as shown in FIG. 21, and the server BMC can write the U-bit ID to the server power supply using the IPMI instruction set (software layer) and write to the MCU on the PSU secondary side. Among them, IPMI (INTELLIGENT PLATFORM MANAGEMENT INTERFACE) is an industry standard adopted by peripheral devices of an Intel-architecture enterprise system.

Further, the flow of the Server BMC writing the U-bit ID to the Server PSU is shown in fig. 22, and includes the following steps S2201 to S2205:

Step S2201: the U-bit operation management platform (equivalent to the preset management platform in the above embodiment) software generates a U-bit ID number.

Step S2202: the server BMC receives the U-bit ID number and judges whether a set server of the U-bit ID number is the server of the server; if not, the U-bit operation management platform is required to confirm the PLC path (i.e., confirm the power supply), and if so, step S2203 is performed.

Step S2203: the server BMC judges whether the received U-bit ID number is repeated with the current number of the server, if so, the U-bit operation management platform provides the U-bit ID again; if not, step S2204 is executed.

Step S2204: if the writing of the U bit ID by the server PSU is successful, step S2205 is executed, otherwise, step S2203 is returned, and the BMC is informed of the re-writing through the I2C path.

In step S2205, the PSU completes the U-bit ID writing.

Furthermore, it should be further noted that the power supply with the power line communication function in the embodiment of the present application is connected to the server, and the design of the power supply can be directly connected to the live wire (L: live wire) and the neutral wire (N: neutral wire) of the power line in a lap joint manner.

And forming a communication power supply network according to the corresponding equipment overlapped by the power line capacity.

Further, the U-bit operation management platform receives and transmits messages through a PLC modem (corresponding to the power line communication modem in the above embodiment) and a communication power network, as shown in fig. 23. The PLC Modem is a Modem which performs broadband internet access through a power line and has the characteristics of plug and play, and is commonly called as a power cat.
