[0046] Application Overview

[0047] The current scale of the communications industry is already very large, with network equipment density, network bandwidth, and business traffic all experiencing substantial growth. The related network energy consumption has also grown along with the growth of business and traffic, especially in data centers, communication base stations / computer rooms, enterprise computer rooms, and other scenarios where the density of communication network equipment is high. In the context of "dual carbon" and "green ICT infrastructure", facing such a large scale of communication network equipment, how to monitor, analyze, and apply the energy consumption of communication network equipment will be a huge challenge.

[0048] The existing communication network equipment energy consumption monitoring, energy consumption analysis, and energy saving analysis mainly include the following:

[0049] Solution 1: Independent energy consumption collection system + energy consumption analysis management platform. The energy consumption collection system includes various energy consumption collection devices (AC meters, DC meters, mutual inductors, etc.), energy consumption communication gateways (4G / 5G / NBIOT / CPE and other wired or wireless gateways), and the energy consumption analysis management platform includes energy consumption data Internet of Things collection platform, energy consumption data analysis platform, etc. This method realizes the unified and centralized collection and monitoring of energy consumption data through an independent energy consumption collection system, and conducts platform-based data analysis and research on the collected energy consumption data. On the one hand, it realizes the management of energy consumption data, and on the other hand, it attempts to realize energy-saving suggestions and energy-saving plans through energy consumption data analysis;

[0050] Solution 2: Indirect network traffic data collection platform + energy consumption analysis platform. By obtaining network traffic data from the communication network equipment network management platform, data model analysis is performed on business activities and traffic patterns, attempting to indirectly achieve energy consumption management and energy-saving control;

[0051] Solution 3: Energy consumption monitoring and energy-saving control based on air conditioning. Most communication network equipment needs to be equipped with air conditioning to achieve temperature control, and air conditioning energy consumption accounts for about 40% of the total energy consumption. Therefore, by monitoring the energy consumption and energy-saving control of air conditioning, the energy consumption and energy-saving management of the auxiliary HVAC part of communication network equipment can be achieved.

[0052] However, the above solution has the following problems:

[0053] Independent energy consumption collection system + energy consumption analysis management platform Disadvantages: A large amount of hardware collection equipment is required, which is costly; a large amount of engineering construction is required; it is impossible to monitor and analyze energy consumption at the equipment level, and currently most of them can only be done at the cabinet level. Energy consumption data and network equipment status and business traffic cannot be synchronized and analyzed in real time;

[0054] Disadvantages of the indirect network traffic data collection platform + energy consumption analysis platform: Network traffic data is managed by a dedicated security network management platform, and the collection interface and network interface of the collection platform are restricted by the network management platform. The communication network equipment traffic data cannot be synchronously analyzed with the corresponding energy consumption data;

[0055] Disadvantages of energy consumption monitoring and energy-saving control based on air conditioning: This solution is only focused on air conditioning energy consumption analysis and air conditioning energy-saving control, and fails to analyze the energy consumption of the communication network equipment itself. However, the fact is that the energy consumption generated by the communication network equipment is the root cause of the energy consumption of the air conditioning equipment. If the energy consumption of the communication network equipment itself can be reduced, the energy consumption of the air conditioning can be greatly reduced. If the business flow and energy consumption of the communication network equipment can be accurately analyzed, the air conditioning can be more accurately regulated, the energy consumption trend can be predicted, and the refined energy consumption management and energy-saving management can be realized.

[0056] In summary, the existing technology cannot perform real-time analysis on the energy consumption of communication network equipment.

[0057] In response to the above technical problems, the present application provides a CPE gateway device that integrates the functions of energy consumption monitoring and energy consumption analysis, thereby ensuring synchronous and real-time analysis of network traffic, temperature and energy consumption data, so as to at least solve the problem in the prior art that the energy consumption of communication network equipment cannot be analyzed in real time.

[0089] It is worth mentioning that the utility model provides a chip-level multifunctional CPE gateway device that integrates energy consumption analysis, realizes a low-cost communication network equipment device that does not add additional hardware energy consumption collection devices and integrates energy consumption monitoring and energy consumption analysis functions. This device can solve the needs of energy consumption monitoring, energy consumption analysis and other needs for communication network equipment, and does not need to rely on other auxiliary energy consumption collection hardware, software analysis platforms, and construction deployment. The energy consumption metering and analysis costs of this device are extremely small and can be ignored.

[0090] In an optional embodiment, based on Figure 1 The CPE gateway device shown can implement energy consumption analysis using the following energy consumption analysis method:

[0091] 1. Energy consumption metering solution

[0092] Whether the communication network equipment is powered by DC or AC, it must eventually be converted to a DC power system. Commonly used communication network equipment power supply solutions are as follows:

[0093] (1) AC220V power supply + built-in AC / DC power supply

[0094] (2) AC220V power supply + external AC / DC adapter

[0095] (3) DC48 power supply / other DC + AC / DC power supply built-in

[0096] (4) DC48 power supply / other DC + external AC / DC adapter

[0097] Regardless of the type of power supply of the communication network equipment, its power supply system can be unified as the DC power supply 11 of this device: by directly measuring the energy consumption of the DC power supply or the DC power supply after ACDC conversion, the energy consumption of the entire communication network equipment can be collected and measured, and the DC power supply energy consumption is the "net energy consumption" of the communication network equipment, which does not include the conversion efficiency of the AC power supply, and can better reflect the actual energy consumption of the communication network equipment, and the energy consumption analysis is more accurate. Compared with the transformer AC energy consumption metering solution, the DC energy consumption metering solution omits the current and voltage transformers, saving space and cost; compared with the non-transformer AC energy consumption metering solution, the DC energy consumption metering solution omits the electrical isolation circuit, saving isolation costs.

[0098] The metering chip selected for the energy consumption metering scheme of the CPE gateway device realizes the DC energy consumption metering function by turning off the high-pass filtering function of the AC universal metering chip. The metering cost of this scheme is only about 20% of the cost of a dedicated DC energy consumption metering chip.

[0099] The DC power supply 11 is the measurement object of the DC energy consumption. The voltage and current signals of the DC power supply 11 are sampled and sent to the energy consumption metering circuit 12, and the energy consumption metering circuit 12 completes the measurement of the energy consumption data. The voltage signal sampling is achieved by a resistor voltage division method, and the voltage sampling signal obtained by the resistor voltage division is sent to the metering chip of the energy consumption metering circuit 12. The current signal sampling is achieved by a mΩ-level current sampling resistor, and the mΩ-level current sampling resistor is connected in series to the negative electrode of the DC power supply 11, one end of the mΩ-level current sampling resistor is connected to the negative electrode of the DC power supply 11, and the other end is connected to the negative electrode of the operation processing unit 2 and is simultaneously connected to the current signal sampling interface of the metering chip.

[0100] 2. Air inlet and outlet and network CPU temperature monitoring solution

[0101] The power supply, network CPU, network processing chip and other parts of the communication network equipment are the main heat sources of the whole machine. As the heat continues to rise, the temperature inside the equipment casing will continue to rise, so most communication network equipment casings have air inlets and outlets designed; cold air enters from the air inlet, and hot air exits from the air outlet. The temperature monitoring solution collects and monitors the air inlet temperature (cold air temperature), air outlet temperature (hot air temperature), and network CPU temperature (typical heat source) in real time, such as Figure 5 shown. Figure 5 4 is the shell of the device, 41 is the air inlet of the shell, 42 is the air outlet, 31 is the temperature sensor 1 (monitoring the air inlet temperature), 32 is the temperature sensor 2 (monitoring the temperature of the heat source such as the network CPU), and 33 is the temperature sensor 3 (monitoring the air outlet temperature).

[0102] By real-time monitoring of the air inlet temperature, air outlet temperature, network CPU and other heat source temperatures of the device, the system can model and analyze the cold air inlet temperature, hot air outlet temperature, network CPU heat source temperature, temperature difference, and temperature thermal field distribution of the device, which is part of the energy consumption analysis of the device.

[0103] 3. Energy consumption analysis plan

[0104] The energy consumption analysis refers to a unified analysis model for the device's energy consumption, energy efficiency, temperature rise, thermal balance, heat dissipation coefficient, unit flow power consumption, energy consumption flow distribution diagram, network CPU utilization, and other dimensions. By analyzing the model, the device's heat dissipation status, energy efficiency status, the relationship between business flow and energy consumption, energy efficiency level, temperature rise trend, energy consumption trend, and energy-saving suggestions can be monitored, mastered, and predicted.

[0105] The energy consumption analysis is realized by the network CPU 21 of the device performing multi-dimensional analysis on the air inlet temperature data, air outlet temperature data, network CPU temperature data, energy consumption data, synchronization time data, traffic service type, traffic size, traffic direction, and port bandwidth data:

[0106] (1) Synchronous time data acquisition: The synchronous time data is acquired by the network CPU from the RTC clock of this device.

[0107] (2) Traffic service type collection: Traffic service type is realized through packet header detection of IP packets. It should be noted that this device has DPDK network hardware acceleration and VPP vector packet processing and analysis, and the analysis of each packet data achieves line-speed, lossless network processing performance.

[0108] (3) Traffic size collection: The traffic size is calculated by statistically analyzing the sizes of different types of messages. It should be noted that this device is equipped with DPDK network hardware acceleration and VPP vector packet processing and analysis, and the traffic size collection and calculation of each packet of data achieves line-speed, lossless network processing performance.

[0109] (4) Traffic direction collection: Traffic direction is divided into port sending direction, port receiving direction, IP address-based sending direction, IP address-based receiving direction, etc. The traffic direction of each packet can be marked by pointing to the port number and IP address of each message. It should be noted that this device has DPDK network hardware acceleration and VPP vector packet processing and analysis, and the traffic direction collection and calculation of each packet of data achieves line-speed, lossless network processing performance.

[0110] (5) Port bandwidth collection: By performing traffic statistics analysis on the size of the data packets at each port, port bandwidth data collection can be achieved. It should be noted that this device has DPDK network hardware acceleration and VPP vector packet processing and analysis, and achieves line-speed, lossless network processing performance for the collection and calculation of port bandwidth size.

[0111] (6) Establish a multi-dimensional energy consumption model array. The energy consumption refers to the energy consumption of the entire device. First, establish a multi-dimensional real-time data energy consumption model array: P (e, ta, tc, tb, fa, f1...f i ...f N , time), where P represents the multidimensional energy consumption model array at time point, e represents the cumulative energy consumption value of the CPE gateway device at time point, ta represents the air inlet temperature of the CPE gateway device at time point, tc represents the network CPU temperature of the CPE gateway device at time point, tb represents the air outlet temperature of the CPE gateway device at time point, fa represents the real-time cumulative flow value of the CPE gateway device at time point, and f i It represents the cumulative traffic value of the ith traffic service type at time point, N is the number of traffic service types (such as small packets, long packets, sending packets, receiving packets...), and time represents the real time (the data recording period can be set as needed).

[0112] (7) Basic data analysis. Through multiple continuous time model arrays, energy consumption curves, temperature rise curves, temperature balance curves, temperature drop curves, temperature peaks, energy consumption peaks, and various types of flow curves can be established.

[0113] (8) Energy efficiency analysis: The main function of this CPE gateway device (specific forms include SDWAN, IPV6+, computing power gateway but are not limited to these) is to transmit data traffic (including various types of data) through the network. The smallest unit of the transmitted traffic is bit. The so-called energy efficiency can be analyzed by analyzing the energy consumption corresponding to the unit bit traffic. The energy consumption is N, and the energy consumption unit is w; the traffic size is F, and the traffic unit is bit; the energy efficiency is E, then energy efficiency = traffic divided by energy consumption, that is, E = F / N (bit / w, bit / watt). Since the traffic, energy consumption, and time are all in the same array, the energy consumption and traffic in any time period can be statistically analyzed through the data in the two arrays at the corresponding time points. For example: any given two arrays P1 (e1, ta1, tc1, tb1, fa1, f11...f i 1...f N 1, time1), P2(e2, ta2, tc2, tb2, fa2, f12...fi 2...f N 2, time2), then the total energy consumption in the time periods of time2 and time1 is N21=e2-e1, the total flow rate is F21=fa2-fa1, and the average energy efficiency is F21 / N21.

[0114] (9) Analysis of the relationship between flow, energy consumption, and temperature: When flow increases, the energy consumption of the network CPU, network chip, and peripheral circuit increases, and the energy consumption of the corresponding device increases; when the energy consumption of the network CPU, network chip, and peripheral circuit increases, the overall heat generation of the corresponding device increases. When the air inlet temperature, air inlet volume, and air outlet volume remain unchanged, the network CPU temperature tc and the air outlet temperature tb will increase. According to the heat exchange principle, when the air inlet temperature ta decreases, it is beneficial to reduce the network CPU temperature tc and the air outlet temperature tb.

[0115] (10) Temperature model and trend analysis: According to the relationship between flow, energy consumption and temperature, for a specific device, since its heat dissipation method, heat dissipation material, heat dissipation structure and other factors are fixed, the corresponding heat dissipation coefficient is also fixed, that is, a constant. In view of this, by analyzing the curves of the device's air inlet temperature, heat source temperature, flow rate, and air outlet temperature, the model curves of flow, air inlet temperature, heat source temperature, and air outlet temperature under different working conditions (air inlet temperature, flow rate) can be analyzed. Such as temperature rise curve and trend, temperature drop curve and trend. By analyzing the laws of temperature rise, temperature balance, and temperature drop under a large number of working conditions (inlet and outlet temperature, flow rate, network CPU utilization), a temperature trend model of the device under different working conditions can be established.
