Abstract
Description
Technical Field
[0001] The present application relates to the field of data processing technology, and in particular to a control method, device, equipment, medium and product for monitoring an electric energy meter. Background Art
[0002] Traditional energy meters are mainly used for energy measurement, but with the construction of smart grids and the increasing requirements for power quality, energy meters need to have more comprehensive monitoring capabilities to reflect the operation status of the power grid in real time. In the modern power grid environment, it is particularly important to quickly detect voltage fluctuations, phase sequence changes, and load imbalances, which has prompted energy meters to transform from single energy metering devices to multifunctional grid signal monitoring devices to support the stable and efficient operation of the power system.
[0003] In the prior art, a sampling rate is set to collect the input signal of the energy meter, and energy metering and grid signal monitoring are performed based on the input signal. Energy metering is performed based on the input signal to accumulate energy data, thereby improving the accuracy and stability of energy metering; at the same time, grid signal monitoring is performed based on the input signal to capture changes in the state of the grid in real time, such as voltage fluctuations and frequency deviations, and quickly execute preset response measures when abnormal conditions are detected, such as issuing an alarm or starting a protection mechanism.
[0004] However, the problem in the prior art is that it is impossible to take into account both the high-precision requirements of electric energy metering and the fast response requirements of grid signal monitoring when performing electric energy metering and grid signal monitoring. If a slower sampling rate is used to ensure the accuracy of electric energy metering, the response time of grid signal monitoring is too long and grid faults cannot be detected in time; while a faster sampling rate can reduce the response time of grid signal monitoring, it will lead to a decrease in the accuracy of electric energy metering and fail to provide accurate metering results.

[0079] In order to clearly describe the technical solutions of the embodiments of the present application, some terms and technologies involved in the embodiments of the present application are briefly introduced below:
[0080] Energy metering: refers to the process of measuring and recording the electrical energy consumed or generated in the power system. It is usually achieved through metering equipment such as energy meters, aiming to accurately calculate the user's electricity usage in order to calculate electricity bills, energy management and optimize the power system.
[0081] Grid signal monitoring: refers to the process of real-time or regular observation, recording and analysis of grid status changes in the power system. Real-time monitoring and abnormality detection of grid status changes are achieved through the use of sensors, smart meters and monitoring software.
[0082] Fault tree: Fault tree is a systematic analysis tool used to identify the causes and effects of potential failures in complex systems. By constructing a tree-like graphical structure, the fault tree breaks down system failure events into smaller, manageable sub-events, usually using logic gates to represent the relationship between events. This method helps users identify the root causes of system failures, evaluate the probability of failures, and develop corresponding preventive and repair measures to improve system reliability and safety.
[0083] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.
[0084] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0085] In order to clearly understand the technical solution of the present application, the solution of the prior art is first introduced in detail. Electricity metering ensures that electricity consumption data is provided to users for cost control by accurately measuring and recording electricity usage. Grid signal monitoring helps users identify electricity consumption patterns, detect abnormal consumption, and optimize electricity consumption strategies through real-time or regular data collection and analysis, thereby improving energy efficiency and reducing energy costs, and supporting the reliability and stability management of power systems. Electricity metering and grid signal monitoring can improve the efficiency and accuracy of energy management.
[0086] In the prior art, a sampling rate is set to collect the input signal of the electric energy meter, and electric energy metering and grid signal monitoring are performed according to the input signal. Electric energy metering is performed according to the input signal to accumulate electric energy data, thereby improving the accuracy and stability of electric energy metering; at the same time, grid signal monitoring is performed according to the input signal to capture the changes in the state of the grid in real time, such as voltage fluctuations and frequency deviations, and quickly execute preset response measures when abnormal conditions are detected, such as issuing an alarm or starting a protection mechanism. However, if a slower sampling rate is used to ensure the accuracy of electric energy metering, the response time of grid signal monitoring is too long, and grid faults cannot be detected in time; and although a faster sampling rate can reduce the response time of grid signal monitoring, it will cause the accuracy of electric energy metering to decrease, and it is impossible to provide accurate metering results. Therefore, there is a problem in the prior art that when performing electric energy metering and grid signal monitoring, it is impossible to take into account both the high-precision requirements of electric energy metering and the rapid response requirements of grid signal monitoring.
[0087] Therefore, in view of the problem that the existing technology cannot take into account the high-precision requirements of electric energy metering and the rapid response requirements of power grid signal monitoring when performing electric energy metering and power grid signal monitoring, it is found in the study that in order to solve this problem, a hybrid method combining a high-precision electric energy metering algorithm and a rapid response monitoring mechanism can be developed: ① A dual-channel system can be developed, in which one channel focuses on high-precision electric energy metering and the other channel focuses on rapid response power grid signal monitoring. ② An adaptive sampling rate algorithm can be designed to dynamically adjust the sampling rate according to real-time needs to find a balance between accuracy and response speed. ③ Hybrid signal processing technology can be used to combine analog and digital signal processing to improve the overall performance of the system and meet different needs.
[0088] Specific:
[0089] A dual acquisition system can be designed. The collector of this system can collect two signals at the same time. One signal is specially used for high-precision electric energy metering. It is equipped with high-precision sensors and complex digital signal processing algorithms to ensure the accuracy and stability of the measurement. It is suitable for billing and long-term energy consumption analysis. The other signal is used for fast grid signal monitoring. It uses fast-response sensors and simplified real-time processing algorithms. It can quickly capture changes in grid status and realize real-time monitoring and abnormality detection of grid status changes. In order to achieve effective coordination of these two channels, the system can use an intelligent control unit to dynamically adjust the working mode of the two channels according to different application scenarios and needs.
[0090] The control method for monitoring the electric energy meter in the embodiment of the present application successfully solves the contradiction between electric energy metering and power grid signal monitoring in the prior art by introducing a dual input signal processing mechanism. The method receives and distinguishes two input signals: the first input signal is used for power grid signal monitoring, which is suitable for a shorter period of time and can quickly respond to changes in the power grid state and generate control and alarm signals to detect and handle power grid faults in a timely manner; the second input signal is used for electric energy metering, which is suitable for a longer period of time, ensures the accuracy of electric energy metering, and generates multiple electric energy parameters. In this way, while ensuring the accuracy of electric energy metering, a rapid response of power grid signal monitoring is achieved.
[0091] Based on the above creative findings, the technical solution of the present application is proposed.
[0092] The following introduces the application scenario of the control method for monitoring an electric energy meter provided by an embodiment of the present invention. Figure 1 Schematic diagram of an application scenario of the control method for monitoring an electric energy meter provided in an embodiment of the present application. Figure 1 As shown, the application scenario includes a collector 101 , a signal processing module 102 , a relay 103 , a communication module 104 , an interaction module 105 and a power supply module 106 . The collector 101 collects the first input signal and the second input signal, and sends the first input signal and the second input signal to the signal processing module 102; the signal processing module 102 performs grid signal monitoring and electric energy metering according to the first input signal and the second input signal, generates multiple first electric energy parameters, control signals and alarm signals, and sends the control signal to the relay 103, and sends the alarm signal and the multiple first electric energy parameters to the communication module 104; the relay 103 performs an opening or closing operation according to the control signal; the communication module 104 sends the alarm signal and the multiple first electric energy parameters to an external device; the interaction module 105 sends user interaction information to the signal processing module 102, the signal processing module 102 queries multiple third electric energy parameters among the multiple first electric energy parameters according to the user interaction information, the signal processing module 102 sends multiple third electric energy parameters to the interaction module 105, the interaction module 105 displays the multiple third electric energy parameters, and performs user interaction; the power supply module 106 is used to supply power to the electric energy meter monitoring control system.
[0093] The embodiments of the present invention are described below in conjunction with the accompanying drawings.
[0094] Figure 2 Schematic diagram of the control method for monitoring an electric energy meter provided in an embodiment of the present application Figure 1 .like Figure 2 As shown, in this embodiment, the execution subject of the embodiment of the present invention is a signal processing module. Then the control method for monitoring the electric energy meter provided in this embodiment includes the following steps:
[0095] S201: Receive a first input signal and a second input signal sent by a collector.
[0096] Specifically, a communication interface can be set between the signal processing module and the collector to realize signal reception. The first input signal and the second input signal represent the data collected in different time periods respectively. After receiving these signals, the signal processing module can monitor the power grid signal and measure the power usage. The first input signal is an input signal collected in a shorter preset time period, which is suitable for fast power grid signal monitoring so as to generate control signals and alarm signals in time. The second input signal is an input signal collected in a longer preset time period, which is suitable for power metering and can provide more comprehensive power parameters such as voltage value, current value and power value. The first time period can be defined as a fast processing time period to respond to changes in power grid signals in time, while the second time period can be defined as a slow processing time period to ensure the accuracy and integrity of power metering. Among them, the first input signal refers to the input signal in the preset first time period, the second input signal refers to the input signal in the preset second time period, the second time period is longer than the first time period, and the second input signal includes the first input signal.
[0097] S202: Monitor the power grid signal according to the first input signal to obtain a control signal and an alarm signal, and measure electric energy according to the second input signal to obtain a plurality of first electric energy parameters.
[0098] Specifically, after receiving the first input signal, the signal processing module immediately analyzes the changes in the state of the power grid in a short period of time to identify any abnormalities or situations exceeding the preset threshold, thereby generating a control signal for operating the relay and an alarm signal for indicating potential faults. At the same time, the signal processing module uses the second input signal to perform more comprehensive power metering and calculate multiple first power parameters, such as voltage values, current values, and power values. These parameters are used to analyze the changes in the state of the power grid and the use of power in detail, and help external devices perform fault judgment and power management. This implementation method ensures that the system can respond quickly in the short term while also providing long-term power usage data analysis. Among them, multiple first power parameters include voltage values, current values, and power values.
[0099] S203: Send a control signal to the relay, so that the relay performs an opening or closing operation according to the control signal.
[0100] Specifically, the signal can be sent through the electrical connection between the signal processing module and the relay. After analyzing the first input signal, the signal processing module generates a corresponding control signal, which is transmitted to the relay through a wire or wireless communication. After receiving the control signal, the relay performs the corresponding mechanical action according to the instruction of the signal, that is, opens or closes the circuit. This process is used to achieve real-time control of the circuit, ensuring that when abnormal power usage or failure is detected, the corresponding control operation can be quickly executed to protect the safety of the equipment.
[0101] S204: Send an alarm signal and a plurality of first electric energy parameters to a communication module, so that the communication module sends the alarm signal and the plurality of first electric energy parameters to an external device.
[0102] Specifically, the transmission of alarm signals and multiple first electric energy parameters can be realized through the interface between the signal processing module and the communication module. After generating the alarm signal and calculating the multiple first electric energy parameters, the signal processing module transmits these data to the communication module by wired or wireless means. The communication module is responsible for formatting the received data and sending it to the external device through a network connection. The external device can be a computer system or mobile device of the monitoring center. After receiving this information, it is used for real-time fault judgment, alarm processing, and analysis and recording of electric energy parameters. This process ensures the transparency and safety of electric energy use and facilitates remote monitoring and management. Among them, the external device is used to make fault judgments based on the alarm signal and analyze and record the electric energy parameters.
[0103] The present embodiment provides a control method for monitoring an electric energy meter, the method comprising: receiving a first input signal and a second input signal sent by a collector; monitoring a power grid signal according to the first input signal to obtain a control signal and an alarm signal, and performing electric energy measurement according to the second input signal to obtain a plurality of first electric energy parameters; sending a control signal to a relay so that the relay performs an opening or closing operation according to the control signal; sending an alarm signal and a plurality of first electric energy parameters to a communication module so that the communication module sends the alarm signal and the plurality of first electric energy parameters to an external device. A control method for monitoring an electric energy meter achieves the following technical effects: by introducing a dual input signal processing mechanism, the contradiction between electric energy measurement and power grid signal monitoring in the prior art is solved. The method receives and distinguishes the first input signal and the second input signal, which are used for power grid signal monitoring and electric energy measurement respectively. The first input signal corresponds to a shorter time period, which is used to quickly respond to changes in the power grid state, generate control signals and alarm signals, so as to detect and respond to power grid faults in a timely manner; the second input signal covers a longer time period, which is used for accurate electric energy measurement, and generates a plurality of electric energy parameters. In this way, the method achieves a rapid response of power grid signal monitoring while ensuring the accuracy of electric energy measurement.
[0104] In one possible design, S202: monitoring the power grid signal according to the first input signal to obtain a control signal and an alarm signal, and performing electric energy measurement according to the second input signal to obtain a plurality of first electric energy parameters, including:
[0105] S2021. Calculate a plurality of second electric energy parameters according to the first input signal, and perform electric energy measurement according to the second input signal to obtain a plurality of first electric energy parameters.
[0106] Specifically, by receiving the first input signal, the system is able to calculate multiple second electric energy parameters, such as voltage values and phase angles. These parameters are used to monitor the operating status of the electric energy meter in real time and are compared with a preset numerical range to detect any abnormalities. If an abnormality is detected, the system generates a corresponding alarm signal and control signal. The alarm signal is used to notify external equipment to make a fault judgment, while the control signal is used to instruct the relay to perform an opening or closing operation to protect the safety and stability of the power system. At the same time, the second input signal is used for electric energy metering over a longer period of time to obtain more comprehensive electric energy parameters, such as voltage values, current values, and power values, which are sent to external equipment for further analysis and recording. Among them, the multiple second electric energy parameters include voltage values and phase angles.
[0107] S2022. Compare the plurality of second electric energy parameters with their corresponding preset value ranges respectively to obtain abnormal monitoring results.
[0108] Specifically, the calculated second electric energy parameter can be analyzed by the signal processing module to compare multiple second electric energy parameters with their corresponding preset value ranges. The system compares each parameter with its corresponding preset value range to identify any deviation from the normal range. This comparison is used to detect abnormal operating conditions of the electric energy meter, thereby generating abnormal monitoring results. If an abnormality is found, the system will generate an alarm signal to indicate that maintenance or inspection is required to ensure the normal operation and safety of the power system.
[0109] S2023. Generate an alarm signal and a control signal based on the abnormal monitoring results.
[0110] Specifically, when the comparison of multiple second power parameters with their preset value ranges shows anomalies, the system automatically generates alarm signals and control signals based on these abnormal monitoring results. The alarm signal is used to notify external equipment or operators for further fault diagnosis and maintenance operations. The control signal is used to instruct the relay to perform the corresponding opening or closing operation to protect the power system in time and prevent potential damage or fault spread. This process ensures the safety and reliability of the power system.
[0111] The technical effect of the solution in this embodiment is that by calculating multiple second electric energy parameters and comparing them with the preset value range, the system can quickly identify abnormal situations and generate corresponding alarm signals and control signals. This not only improves the monitoring accuracy and response speed of the electric energy meter, but also enhances the safety and reliability of the system, ensuring that the power system can take protective measures in a timely manner when abnormalities occur.

[0113] S20211. Determine calculation formulas for multiple first electric energy parameters and calculation formulas for multiple second electric energy parameters according to the connection mode.
[0114] Specifically, the system first identifies the connection method between the collector and the external device, such as three-phase three-wire or three-phase four-wire, and then selects the calculation formula according to the connection method. These formulas are used to calculate the power parameters, where the first power parameter includes voltage value, current value and power value, and the second power parameter includes voltage value and phase angle. By selecting the appropriate calculation formula, the system can accurately process the power data under different connection methods, thereby ensuring the accuracy and reliability of grid signal monitoring and metering. This process supports the system to operate effectively in various power network configurations.
[0115] S20212. Calculate a plurality of second electric energy parameters according to the first input signal and a calculation formula for a plurality of second electric energy parameters.
[0116] Specifically, the system receives a first input signal, which represents the power data collected in a short period of time. Using a predetermined calculation formula, the system processes this data to calculate multiple second power parameters, such as voltage value and phase angle. These parameters are used to monitor the changes in the state of the power grid in real time and compare them with the preset value range to detect any abnormal conditions. This process helps to generate alarm signals and control signals in a timely manner, thereby realizing effective monitoring and management of the power meter.
[0117] S20213. Calculate and obtain multiple first electric energy parameters according to the second input signal and calculation formulas of multiple first electric energy parameters.
[0118] Specifically, the system receives a second input signal that covers power data over a longer period of time. Using a calculation formula predetermined for this connection mode, the system processes this data to calculate multiple first power parameters, such as voltage, current, and power. These parameters are used for detailed power metering and analysis, providing a comprehensive understanding of power consumption, and are sent to external devices through a communication module. External devices can use this data for fault diagnosis, trend analysis, and recording, thereby supporting power management and optimization decisions.
[0119] The technical effect of the scheme in this embodiment is that by clarifying the connection mode between the collector and the external device, the system can select and apply appropriate calculation formulas to accurately calculate the electric energy parameters. This flexibility and adaptability ensures that the grid signal monitoring function and the electric energy metering function of the electric energy meter can be performed efficiently and accurately under different power network configurations, improving the reliability and accuracy of the system, and being able to identify and respond to power anomalies in a timely manner, thereby enhancing the effectiveness and safety of electric energy management.
[0120] In a possible design, S2023, generating an alarm signal and a control signal according to the abnormal monitoring result, includes:
[0121] S20231. According to the preset fault tree, analyze the abnormal monitoring results to obtain the fault type and fault degree.
[0122] Specifically, the analysis of abnormal monitoring results can be achieved by matching and analyzing them with the pre-established fault tree model. The fault tree is a systematic analysis tool that includes possible fault events and their interrelationships. By comparing the monitored abnormal data with the nodes in the fault tree, the specific fault type, such as overload, short circuit, etc., and the severity of the fault, such as minor, severe, etc., can be identified. This process helps to quickly locate the root cause of the problem and generate corresponding alarm signals and control signals so that timely measures can be taken for fault handling and system maintenance.
[0123] For example, the voltage value of the collected multiple second electric energy parameters exceeds the preset detection upper limit. According to the preset fault tree, this situation is identified as an overvoltage fault. The fault tree will further analyze the severity of the overvoltage fault, such as determining whether it is a slight overvoltage or a severe overvoltage. Based on the analysis results, the system generates a corresponding overvoltage alarm signal and a control signal at the same time. The control signal will be sent to the relay, instructing the relay to perform the corresponding operation, such as disconnecting the circuit to protect the equipment and prevent damage caused by overvoltage.
[0124] S20232. Generate an alarm signal and a control signal according to the fault type and fault severity.
[0125] Specifically, based on the type of fault identified and its severity, the system will call the corresponding response strategy, which defines the actions to be taken in different fault scenarios. For example, for a minor fault, the system may only generate an alarm signal to alert maintenance personnel, while for a serious fault, the system may generate a control signal to automatically disconnect the relevant circuit to prevent further damage. The purpose of this is to ensure that the energy meter system can respond quickly when a fault occurs, ensuring the safety and stable operation of the system.
[0126] The technical effect of the scheme in this embodiment is: by using the preset fault tree to analyze the abnormal monitoring results, the fault type and fault degree are accurately identified, thereby generating corresponding alarm signals and control signals, improving the efficiency of fault detection and response, and enabling the system to quickly locate and classify faults, and then take appropriate measures to deal with them. This method not only reduces the need for manual intervention, but also reduces the downtime of the system caused by faults, and improves the reliability and safety of the electric energy meter system.

[0128] S2011. In a first time period after the target time point starts, an interrupt signal is sent to a collector to enable the collector to generate a first input signal.
[0129] Specifically, a specific trigger signal can be sent through the signal processing module, which instructs the collector to start collecting and recording power data within the time period, thereby generating a first input signal. The purpose of this process is to ensure that the collector can accurately collect power data within a preset time period in order to perform real-time grid signal monitoring and analysis. The sending of this interrupt signal can be achieved through hardware interrupts or software instructions, depending on the system design and the interface requirements of the collector. In this way, the system can obtain the necessary data in a timely manner for subsequent grid signal monitoring, control signal generation, and alarm signal generation.
[0130] S2012. Receive a first input signal sent by a collector.
[0131] Specifically, the first input signal can be received through the communication interface between the signal processing module and the collector, and the interface can be a wired connection or a wireless connection. The signal processing module reads the data packet sent by the collector through the interface to ensure that real-time power data is obtained within the first time period. The purpose of this process is to monitor the changes in the power grid state in real time, generate corresponding control signals and alarm signals, so as to respond to abnormal power conditions in a timely manner and improve the safety and reliability of the system.
[0132] S2013: In a second time period after the target time point, the collector is used to generate a second input signal, and then the second input signal sent by the collector is received.
[0133] Specifically, the signal processing module receives this data through the communication interface with the collector, which includes more comprehensive power parameters such as voltage, current and power values. The purpose of this process is to perform detailed power metering and analysis to obtain multiple first power parameters, thereby providing the system with accurate power usage information and supporting external devices to perform fault judgment and power parameter analysis and recording. This detailed data collection helps long-term power management and optimization.
[0134] The technical effect of the scheme in this embodiment is: by periodically collecting input signals and generating the first and second input signals within a specific time period, the system can ensure that the first input signal is obtained in a short time for real-time monitoring and rapid response. At the same time, the second input signal is collected over a longer period of time to support detailed grid signal monitoring and power metering. This method improves the response speed and data accuracy of the system, helps to detect power anomalies in a timely manner, and improves the efficiency and reliability of power management.

The interaction module can be a user interface including a display screen and an input device, through which the user can input query requests or other instructions. After receiving these input information, the system parses the user's request and queries the stored power parameters according to the request content.

The user inputs specific query requests through the interaction module, and the signal processing module receives and parses these requests to identify the multiple third power parameters required by the user. The system then extracts these specific parameters from the stored multiple first power parameters and sends them back to the interaction module for display. This function can provide users with customized data access, enabling users to obtain specific power information according to their needs for more accurate monitoring, analysis and decision-making.
[0145] S307: Send multiple third power parameters to the interaction module, so that the interaction module displays the multiple third power parameters.
[0146] Specifically, multiple third power parameters can be sent to the interaction module through the communication interface between the signal processing module and the interaction module. After receiving the user's query request, the signal processing module extracts the required multiple third power parameters and transmits these parameters to the interaction module through the communication protocol within the system. After receiving the data, the interaction module formats it and displays it on a user interface, such as a display screen or a touch screen. This function can provide users with an intuitive display of power parameter information, allowing users to easily view and analyze specific power data, thereby supporting real-time monitoring and decision-making.
