[0058] Embodiments of the present application are described in detail below with reference to examples thereof shown in the attached drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and are not to be understood as limiting the present application.

[0059] An electric energy metering box is a device used to measure and record power consumption, which is crucial for monitoring and managing the power grid. With the advancement of Internet of Things technology, its application in electric energy metering boxes can achieve real-time monitoring, thereby improving the prediction and early warning capabilities of safety problems in electric energy metering boxes. Specifically, by collecting and analyzing data of electric energy metering boxes, preventive measures can be taken before potential failures occur, thereby ensuring the safe operation of the device.

[0060] In related technologies, in order to protect the safety of electric energy metering boxes, an overload protector is usually installed in the electric energy metering box. This protector will automatically cut off the power supply when the current exceeds the set threshold, to prevent damage to the device or safety accidents such as fire, to ensure that the load condition of the electric energy metering box is in a protected state, thereby reducing the risk and improving safety.

[0061] However, the overload protector determines the load condition by the size of the current, so that the preset threshold is a fixed value. This fixed threshold overload protector has certain limitations when the environmental temperature changes. Because the change of environmental temperature will affect the resistance value of the wire, thereby affecting the load current. When the temperature rises, the wire resistance increases, which may cause the actual heat generation of the line to increase within the originally set threshold range, thereby causing the line to overheat or be damaged under high temperature conditions. In this case, even if the current does not exceed the fixed threshold, the line may still have safety problems due to overheating.

[0062] Based on this, the embodiment of the present specification provides an electric energy metering box early warning management system. The electric energy metering box comprises an overload protector. The electric energy metering box early warning management system comprises a box temperature processing module, an external environment temperature acquisition module, an electric data monitoring and analysis module, and a load adjustment module. First, the box temperature processing module is used to collect the temperature in the electric energy metering box, and the collected temperature data is processed to obtain the temperature change curve in the box. The external environment temperature acquisition module is used to collect the environmental temperature where the electric energy metering box is located to obtain environmental temperature data. The electric data monitoring and analysis module is used to monitor the electric data of the electric energy metering box to obtain current data and voltage data. Then, the load adjustment module determines the ideal load data of the corresponding line of the electric energy metering box based on the temperature change curve in the box, the environmental temperature data, the current data and the voltage data, and adjusts the load threshold of the overload protector according to the ideal load data.

[0063] By collecting the temperature in the box and the external environment temperature, the corresponding line temperature data is determined. Since the effective load of the line changes with the change of temperature, the load adjustment module judges the maximum load of the line based on the temperature change curve in the box, the environmental temperature data, the current data and the voltage data, so that the preset load threshold in the overload protector can be adjusted in real time according to the current line state, thereby ensuring that the overload protector can accurately alarm the overload phenomenon of the line, and improving the accuracy and timeliness of the early warning result.

[0064] The embodiment of the present specification provides an electric energy metering box early warning management system 100, please refer to Figure 1 The electric energy metering box comprises an overload protector, and the system can comprise:

[0065] The box temperature processing module 102 is used to collect the temperature in the electric energy metering box, and process the collected temperature data to obtain the temperature change curve in the box.

[0066] Specifically, the box temperature processing module 102 is arranged in the electric energy metering box to monitor the temperature change in the box. The box temperature processing module 102 collects the temperature data in the electric energy metering box through a temperature sensor at regular intervals. These temperature data record the temperature information at different time points. Then, the box temperature processing module 102 arranges these temperature data in time sequence to form a time sequence. Based on the time sequence, the box temperature processing module 102 draws a two-dimensional temperature change curve in the box, in which the horizontal axis represents time and the vertical axis represents temperature value.

[0067] The external environment temperature acquisition module 104 is used to collect the environmental temperature where the electric energy metering box is located to obtain environmental temperature data.

[0068] The electric data monitoring and analysis module 106 is configured to monitor the electric data of the electric energy metering box to obtain current data and voltage data.

[0069] Specifically, the box external environment temperature acquisition module 104 is responsible for monitoring the ambient temperature outside the electric energy metering box. The box external environment temperature acquisition module 104 acquires the temperature data outside the electric energy metering box in real time through the ambient temperature sensor to obtain the ambient temperature data. The ambient temperature data is used to understand the temperature condition of the environment where the electric energy metering box is located, so as to analyze the possible influence of the ambient temperature on the temperature in the box and the electric energy metering system. The electric data monitoring and analysis module 106 is equipped with a current sensor and a voltage sensor, which are used to monitor the electrical parameters of the electric energy metering box in real time to obtain current data and voltage data.

[0070] The load adjustment module 108 determines the ideal load data of the corresponding line of the electric energy metering box based on the box internal temperature change curve, the ambient temperature data, the current data and the voltage data, and adjusts the load threshold of the overload protector according to the ideal load data.

[0071] Specifically, the load adjustment module 108 is signal connected with the box internal temperature processing module 102, the box external environment temperature acquisition module 104 and the electric data monitoring and analysis module 106, and receives the box internal temperature change curve, the ambient temperature data, the current data and the voltage data. The load adjustment module 108 comprehensively analyzes the collected data. Based on the box internal temperature change curve and the ambient temperature data, the load adjustment module 108 determines the thermal environment of the electric energy metering box, understands the thermal load distribution inside and outside the box, and identifies potential temperature abnormal conditions. Combined with the current and voltage data, the load adjustment module 108 evaluates the actual state of the electrical load. Therefore, the load adjustment module 108 uses the above data to consider the influence of temperature on the performance of electrical components, and calculates the ideal load data of the corresponding line of the electric energy metering box. The ideal load data considers the influence of temperature and the actual demand of electrical load to optimize the load performance and protect the stability of the system. According to the ideal load data calculated, the load threshold of the overload protector is adjusted to ensure that the overload protector can be disconnected in time when the load exceeds the safe range, so as to protect the electric energy metering box and the internal equipment thereof.

[0072] The power metering box pre-warning management system includes an in-box temperature processing module, an out-of-box environment temperature collecting module, an electric data monitoring and analyzing module, and a load adjusting module. First, the in-box temperature processing module collects the in-box temperature of the power metering box, processes the collected temperature data, and obtains an in-box temperature change curve. The out-of-box environment temperature collecting module collects the environment temperature in which the power metering box is located, and obtains environment temperature data. The electric data monitoring and analyzing module monitors the electric data of the power metering box, and obtains current data and voltage data. Then, the load adjusting module determines ideal load data of a corresponding line of the power metering box based on the in-box temperature change curve, the environment temperature data, the current data, and the voltage data, and adjusts the load threshold of the overload protector according to the ideal load data.

[0073] The in-box temperature and the out-of-box environment temperature are collected to determine corresponding line temperature data. Since the effective load amount of the line changes with the temperature, the load adjusting module judges the maximum load amount of the line based on the in-box temperature change curve, the environment temperature data, the current data, and the voltage data, so that the preset load threshold in the overload protector can be adjusted in real time according to the current line state, thereby ensuring that the overload protector can accurately alarm the overload phenomenon of the line, and improving the accuracy and timeliness of the pre-warning result.

[0074] In some embodiments, referring to Figure 2 , the in-box temperature processing module 102 can include:

[0075] The temperature collecting unit 202 is configured to collect the in-box temperature of the power metering box, and obtain temperature collecting data.

[0076] Specifically, a plurality of temperature collecting units 202 are arranged in the power metering box, and the plurality of temperature collecting units 202 are evenly distributed in the internal space of the power metering box, so as to collect the temperature data in the power metering box in real time, and obtain a plurality of temperature collecting data. It should be noted that the positions of all working devices in the power metering box are marked on an imaginary plane. The plane represents the actual distribution positions of the working devices in the power metering box. The positions of all temperature collecting units are marked on another plane in the power metering box. In order to ensure the accuracy of the temperature collecting data, the two planes are kept parallel, so that the vertical distance between each temperature collecting unit and the working devices in the power metering box is kept consistent. In this way, the temperature collecting error caused by different heights or distances can be eliminated.

[0077] The temperature processing unit 204 is configured to process and analyze the temperature collecting data, and obtain a temperature distribution diagram.

[0078] Specifically, the temperature processing unit 204 is in signal connection with the temperature collection unit 202 and receives a plurality of temperature collection data. The temperature processing unit 204 classifies and summarizes the temperature collection data according to the collection time of the temperature collection data. The temperature processing unit 204 summarizes the temperature collection data of a plurality of temperature collection units at the same collection time, and draws a temperature distribution map using the summarized temperature collection data. The temperature of each region in the map is identified by different colors, so as to intuitively represent the temperature change of different regions. It should be noted that each collection time corresponds to a temperature distribution map.

[0079] The temperature curve drawing unit 206 is configured to receive the temperature distribution map and calculate the same to obtain a temperature change curve in the box.

[0080] Specifically, the temperature curve drawing unit 206 is in signal connection with the temperature processing unit 204 and receives the temperature distribution map. The temperature curve drawing unit 206 analyzes the temperature distribution map to determine whether the temperature distribution of different regions on the temperature distribution map is consistent. In the case that a plurality of temperature collection data displayed on the temperature distribution map is the same, it indicates that the working equipment in the electric energy metering box is normally operated and generates uniform heat. At this time, the temperature curve drawing unit 206 directly takes the temperature collection data as the temperature mean value data. In the case that a plurality of temperature collection data displayed on the temperature distribution map is not the same, it indicates that there is an individual working equipment that is generating high heat. Therefore, the working equipment needs to be analyzed. At this time, the temperature curve drawing unit 206 determines the heat source inside the electric energy metering box according to the temperature distribution map, and calculates the mean value of the temperature collection data collected by the temperature collection unit around the heat source, that is, identifies the region with the highest temperature in the temperature distribution map, and calculates the mean value of a plurality of temperature collection data in a preset range including the highest temperature collection data in the temperature distribution map to obtain the corresponding temperature mean value data. Finally, the temperature curve drawing unit 206 converts the above temperature mean value data into a temperature change curve according to the time sequence, which reflects the temperature change in the electric energy metering box.

[0081] In the above-mentioned electric energy metering box early warning management system, the temperature collection unit collects the temperature in the electric energy metering box to obtain temperature collection data, the temperature processing unit processes and analyzes the temperature collection data to obtain a temperature distribution map, and the temperature curve drawing unit receives the temperature distribution map and calculates the same to obtain a temperature change curve in the box, thereby providing a data basis for subsequent load adjustment.

[0082] In some embodiments, referring to Figure 3 , the electric data monitoring and analyzing module 106 can include:

[0083] The electric data monitoring unit 302 is configured to monitor the electric data of the electric energy metering box to obtain current data and voltage data.

[0084] Specifically, the electric data monitoring unit 302 is responsible for monitoring the electric data in the electric energy metering box in real time. The unit can include a plurality of measuring devices, such as ammeters and voltmeters, for measuring the current and voltage data of the electric energy metering box, respectively. These measuring devices transmit the collected current and voltage data to the electric data monitoring unit 302 to ensure real-time updating and recording of the running state of the electric energy metering box.

[0085] The load calculation unit 304 is configured to process the current data and voltage data to obtain load data.

[0086] The temperature conversion unit 306 is configured to calculate the load data and the current data to obtain output heat data of the corresponding line of the electric energy metering box and first temperature data in the case of no heat dissipation.

[0087] Specifically, the load calculation unit 304 is in signal connection with the electric data monitoring unit 302 to receive the current data and voltage data. The load calculation unit 304 divides the voltage data by the current data to obtain the load data.

[0088] The temperature conversion unit 306 is built-in with a heat calculation formula and a basic thermodynamic energy balance equation. The temperature conversion unit 306 is in signal connection with the load calculation unit 304 to receive the load data and in signal connection with the electric data monitoring unit 302 to receive the current data. The temperature conversion unit 306 determines the output heat data of the corresponding line of the electric energy metering box based on the heat calculation formula, i.e., Joule's law: , where is the output heat data, is the current data, is the load data, is the time. It should be noted that the time may be 1. Then, the temperature conversion unit 306 determines the first temperature difference value according to the basic thermodynamic energy balance equation: , where is the output heat data (Joule, J), is the mass of air (kilogram, kg), is the specific heat capacity of air (Joule / kilogram·Celsius, J / kg·℃), is the temperature difference value (Celsius, ℃). It should be noted that the mass of air can be determined according to the volume data of the electric energy metering box and the air density. Finally, the temperature conversion unit 306 performs summation operation on the current box temperature data and the first temperature difference value to determine the first temperature data in the case of no heat dissipation.

[0089] The temperature comparison unit 308 is configured to compare the first temperature data with the line safety temperature data, and determine a determination result.

[0090] Specifically, the temperature comparison unit 308 is internally provided with the line safety temperature data. The temperature comparison unit 308 is in signal connection with the temperature conversion unit 306, and receives the first temperature data. The temperature comparison unit 308 compares the first temperature data with the line safety temperature data. In a case where the first temperature data is less than or equal to the line safety temperature data, it is determined that there is no overload phenomenon in the line. In a case where the first temperature data is greater than the line safety temperature data, it is determined that the line is to be determined. The cases of no overload phenomenon and the line to be determined are collectively marked as the determination result.

[0091] It should be noted that the line generates heat due to the current passing through during operation. If the temperature of the line is too high, it may cause aging of the insulation material, overheating of the line, and even cause a fire. Therefore, the safety temperature data is set to prevent equipment damage or safety accidents caused by abnormal temperature.

[0092] The result output unit 310 is configured to output the determination result.

[0093] Specifically, the result output unit 310 is in signal connection with the temperature comparison unit 308, and receives the determination result. The result output unit 310 is in signal connection with the overload determination module 500, and outputs the received determination result to the overload determination module 500.

[0094] In the above-mentioned power metering box early warning management system, the electric data monitoring unit monitors the electric data of the power metering box to obtain current data and voltage data. The load calculation unit processes the current data and the voltage data to obtain load data. The temperature conversion unit calculates the load data and the current data to obtain output heat data of the line corresponding to the power metering box and the first temperature data under the condition that no heat dissipation occurs. The temperature comparison unit compares the first temperature data with the line safety temperature data to determine a determination result. The result output unit outputs the determination result. Through the comprehensive monitoring and data processing functions, the monitoring and safety protection can be realized, and the operation efficiency and safety of the system can be improved.

[0095] In some embodiments, referring to Figure 4 , the power metering box early warning management system 100 further comprises a temperature data analysis module 400, and the temperature data analysis module 400 comprises:

[0096] The ideal temperature calculation unit 402 is configured to perform thermodynamic calculation based on the output heat data to obtain an ideal temperature change rate.

[0097] Specifically, the ideal temperature calculation unit 402 is in signal connection with the electric data monitoring and analysis module 106, receives the output heat data of the corresponding line of the electric energy metering box determined by the temperature conversion unit 306 included in the electric data monitoring and analysis module 106. The ideal temperature calculation unit 402 is internally provided with the volume data of the current electric energy metering box and the basic thermodynamic energy balance equation.

[0098] The ideal temperature calculation unit 402 determines the temperature change in the box under the action of the output energy data according to the basic thermodynamic energy balance equation, i.e., the basic thermodynamic energy balance equation: , to obtain the ideal temperature change rate of the temperature in the box in the state of no heat dissipation. Wherein, is the output energy data (joule, J), is the mass of air (kilogram, kg), is the specific heat capacity of air (joule / kilogram·degree Celsius, J / kg·℃), is the ideal temperature change rate (degree Celsius, ℃). It should be noted that the mass of air can be determined according to the volume data of the electric energy metering box and the air density.

[0099] The heat dissipation efficiency calculation unit 404 is used to obtain the heat dissipation efficiency corresponding to the electric energy metering box based on the temperature change curve in the box and the ideal temperature change rate.

[0100] Specifically, the heat dissipation efficiency calculation unit 404 is in signal connection with the temperature in the box processing module 102, receives the temperature change curve in the box determined by the temperature curve drawing unit 206 included in the temperature in the box processing module 102, and is in communication connection with the ideal temperature calculation unit 402, receives the ideal temperature change rate. The heat dissipation efficiency calculation unit 404 analyzes the temperature change curve in the box to obtain the actual temperature change rate of the current temperature in the box. Then the heat dissipation efficiency calculation unit 404 calculates the difference between the ideal temperature change rate and the actual temperature change rate to obtain the heat dissipation efficiency corresponding to the electric energy metering box.

[0101] The line temperature calculation unit 406 is used to determine the target temperature data in the box according to the temperature change curve in the box, determine the temperature difference value of the electric energy metering box according to the target temperature data in the box and the environmental temperature data, and determine the heat dissipation coefficient and the first line temperature data based on the temperature difference value, the target temperature data in the box and the heat dissipation efficiency.

[0102] ​​​​​Specifically, the line temperature calculation unit 406 is connected with the in-box temperature processing module 102 to receive the in-box temperature change curve determined by the temperature curve drawing unit 206 included in the in-box temperature processing module 102, connected with the out-box environment temperature collection module 104 to receive the environment temperature data, and connected with the heat dissipation efficiency calculation unit 404 to receive the heat dissipation efficiency corresponding to the electric energy metering box.

[0103] The line temperature calculation unit 406 analyzes the in-box temperature change curve to determine the in-box temperature data of the electric energy metering box at the current time, i.e., the target in-box temperature data, and performs difference calculation on the target in-box temperature data and the environment temperature data to obtain the temperature difference of the electric energy metering box. Then, the line temperature calculation unit 406 determines the heat dissipation coefficient according to the formula: , wherein, is the heat dissipation efficiency corresponding to the electric energy metering box, is the heat conduction coefficient, i.e., the heat dissipation coefficient, is the temperature difference of the electric energy metering box. Then, the line temperature calculation unit 406 analyzes the in-box temperature change curve to obtain the actual temperature change rate of the current in-box temperature. Since the in-box temperature rising rate is usually higher than the external environment temperature falling rate under the same temperature difference, the heat conduction efficiency of the in-box air is higher than that of the air to the external environment. Based on this, after determining the temperature difference of the electric energy metering box according to the in-box temperature change curve, the line temperature calculation unit 406 continues to determine the temperature difference of the line to the in-box air according to the formula: , wherein, is the actual temperature change rate, is the heat dissipation coefficient, is the temperature difference of the line to the in-box air. Finally, the temperature difference of the line to the in-box air is greater than the temperature difference of the in-box air to the external environment, so after the line determines the temperature difference of the in-box air, the line temperature calculation unit 406 performs summation operation on the target in-box temperature data and the temperature difference of the line to the in-box air, and the line temperature value obtained is greater than the actual line temperature value, so it is understood that the maximum line temperature data of the line corresponding to the current electric energy metering box, i.e., the first line temperature data, is obtained.

[0104] In the power metering box early warning management system, the ideal temperature calculation unit performs thermodynamic calculation based on the output heat data to obtain an ideal temperature change rate, the heat dissipation efficiency calculation unit obtains the heat dissipation efficiency corresponding to the power metering box based on the temperature change curve in the box and the ideal temperature change rate, the line temperature calculation unit determines target box temperature data according to the temperature change curve in the box, determines a temperature difference of the power metering box according to the target box temperature data and ambient temperature data, and determines the heat dissipation coefficient and the first line temperature data based on the temperature difference, the target box temperature data and the heat dissipation efficiency, thereby improving the stability and performance of the system.

[0105] In some embodiments, referring to Figure 4 , the power metering box early warning management system 100 further comprises an overload judgment module 500, and the overload judgment module 500 comprises:

[0106] A temperature trend judgment unit 502 is configured to analyze the temperature change curve in the box to determine trend category data corresponding to the temperature change curve in the box.

[0107] Specifically, the temperature trend judgment unit 502 is in signal connection with the box temperature processing module 102 and receives the temperature change curve in the box determined by the temperature curve drawing unit 206 included in the box temperature processing module 102. The temperature trend judgment unit 502 judges the change trend of the temperature change curve in the box. When the temperature change curve in the box presents an upward trend, the temperature trend judgment unit 502 marks the temperature change curve in the box as an upward category. When the temperature change curve in the box presents a downward trend or a horizontal constant trend, the temperature trend judgment unit 502 marks the temperature change curve in the box as a non-upward category. It should be noted that the upward category and the non-upward category are collectively marked as trend category data.

[0108] An overload judgment unit 504 is configured to receive the trend category data, the first line temperature data, the second line temperature data and the determination result, and in the case that the determination result is a line to be judged, determine the determination result based on the trend category data, the first line temperature data, the line safety temperature data and the second line temperature data.

[0109] Specifically, the overload judging unit 504 receives the determination result output by the result output unit 310. When the determination result is that there is no overload phenomenon in the line, the overload judging unit 504 directly determines that there is no overload phenomenon in the line. When the determination result is that the line is to be determined, different temperature change trends are taken different processing measures, which can make the determination result more accurate. The overload judging unit 504 is internally provided with line safety temperature data. The overload judging unit 504 is signal connected with the temperature trend judging unit 502 to receive the trend category data, and is signal connected with the line temperature calculating unit 406 to receive the first line temperature data. Then the overload judging unit 504 selects the line temperature according to the trend category data. When the trend category data is the non-rising category, it indicates that the current electric energy metering box corresponding line has a lower heating efficiency on the air in the box than the heat dissipation efficiency of the air in the box on the external environment, so the temperature of the electric energy metering box corresponding line is also in a gradually decreasing state, and then the maximum line temperature data of the current line, i.e. the first line temperature data, is taken as the standard for line safety determination, and the result obtained by the determination is more effective and the early warning is more accurate. The overload judging unit 504 compares the first line temperature data with the internally provided line safety temperature data. When the first line temperature data is less than or equal to the line safety temperature data, it is determined that there is no overload phenomenon in the line. When the first line temperature data is greater than the line safety temperature data, it is determined that there is an overload phenomenon in the line.

[0110] In the case that the trend category data is the rising category, it indicates that the current electric energy metering box corresponding line has a higher air heating efficiency in the box than the heat dissipation efficiency of the air in the box to the external environment, so the temperature of the electric energy metering box corresponding line is also in the rising state. The minimum line temperature data, i.e., the second line temperature data, is used for safety judgment, so as to quickly judge whether the electric energy metering box corresponding line is in a safe state under the current state. The overload judgment unit 504 is connected with the minimum line temperature calculation module 602. The overload judgment unit 504 sends a minimum line temperature request signal to the minimum line temperature calculation module 602 and receives the second line temperature data determined by the minimum line temperature calculation module 602. The overload judgment unit 504 compares the second line temperature data with the built-in line safety temperature data. In the case that the second line temperature data is greater than the line safety temperature data, it is determined that the line has an overload phenomenon, which indicates that the line is in a dangerous state at this moment, so a safety alarm is needed, thereby improving the judgment rate. In the case that the second line temperature data is less than or equal to the line safety temperature data, a second safety judgment is needed for the maximum line temperature data, i.e., the first line temperature data, and the line safety temperature data, so as to further determine whether the line is in a safe state under the future state, making the early warning result more accurate. The overload judgment unit 504 compares the first line temperature data with the built-in line safety temperature data. In the case that the first line temperature data is less than or equal to the line safety temperature data, it is determined that the line does not have an overload phenomenon. In the case that the first line temperature data is greater than the line safety temperature data, it is determined that the line has an overload phenomenon. The line without an overload phenomenon and the line with an overload phenomenon are uniformly marked as the judgment result.

[0111] In the above electric energy metering box early warning management system, the temperature trend judgment unit analyzes the temperature change curve in the box to determine the trend category data corresponding to the temperature change curve in the box. Then, the overload judgment unit receives the trend category data, the first line temperature data, the second line temperature data, and the determination result. In the case that the determination result is that the line is to be determined, the overload judgment unit determines the determination result based on the trend category data, the first line temperature data, the line safety temperature data, and the second line temperature data, thereby improving the reliability and early warning accuracy of the system.

[0112] In some embodiments, referring to Figure 4 , the electric energy metering box early warning management system 100 further includes a minimum line temperature calculation module 602 configured to perform data processing based on the target temperature data in the box and the temperature difference value to determine the second line temperature data.

[0113] Specifically, the minimum line temperature calculation module 602 is in signal connection with the temperature data analysis module 400, and receives the temperature difference value determined by the line temperature calculation unit 406 included in the temperature data analysis module 400 and the target box temperature data. The minimum line temperature calculation module 602 performs summation calculation on the temperature difference value and the target box temperature data to obtain the minimum line temperature data, i.e., the second line temperature data.

[0114] The minimum line temperature calculation module 602 is in signal connection with the overload judgment module 500, and receives the minimum line temperature request signal sent by the overload judgment module 500. Then, the minimum line temperature calculation module 602 transmits the second line temperature data to the overload judgment unit 504 included in the overload judgment module 500.

[0115] In the above-mentioned power metering box early warning management system, the minimum line temperature calculation module performs data processing based on the target box temperature data and the temperature difference value to determine the second line temperature data, so that the overload judgment module can more effectively perform overload detection and protection.

[0116] In some embodiments, referring to Figure 4 , the load adjustment module 108 includes:

[0117] It should be noted that the load adjustment module 108 is in signal connection with the overload judgment module 500 and the temperature data analysis module 400.

[0118] In some cases, the line load changes due to the influence of temperature change, so the load detected by the system may be lower than the preset overload protector load threshold. However, even if the detection value is lower than the threshold, the line may still be in an unsafe state. Therefore, it is necessary to re-adjust the threshold of the overload protector to ensure that effective protection can be provided when the actual load exceeds the standard.

[0119] The constant temperature calculation unit 702 is configured to obtain constant output energy based on the judgment result and the line safety temperature data.

[0120] Specifically, the constant temperature calculation unit 702 is built-in with the Stefan-Boltzmann formula for calculating the rate of energy transfer by thermal radiation of an object. In some embodiments, the line safety temperature data can be pre-built in the constant temperature calculation unit 702. In other embodiments, the line safety temperature data can be obtained by the constant temperature calculation unit 702 from other units or modules. For example, the constant temperature calculation unit 702 can receive the line safety temperature data from the overload judgment unit 504.

[0121] Since the line safety temperature data of the line is fixed, the radiant power at the temperature can be determined by taking the line safety temperature data of the line as a variable. The constant temperature calculation unit 702 receives the determination result determined by the overload determination unit 504 included in the overload determination module 500 and judges it. If the determination result is that there is an overload phenomenon, the constant temperature calculation unit 702 applies the Stefan-Boltzmann formula: , for further processing to determine the required constant output energy to ensure that the line operates within a safe temperature range and prevent potential hazards caused by overload. Among them, is the radiant power (watt, W), that is, the constant output energy, is the emissivity of the line corresponding to the electric energy metering box (dimensionless, usually between 0 and 1), is the Stefan-Boltzmann constant, about , is the surface area of the line corresponding to the electric energy metering box (square meters, m²), is the line safety temperature data (kelvin, K).

[0122] The temperature change simulation unit 704 is used for thermodynamic calculation based on the constant output energy and the heat dissipation efficiency to obtain the simulated temperature change rate in the box.

[0123] Specifically, the temperature change simulation unit 704 receives the heat dissipation efficiency of the electric energy metering box determined by the heat dissipation efficiency calculation unit 404 included in the temperature data analysis module 400 and receives the constant output energy determined by the constant temperature calculation unit 702.

[0124] The temperature change simulation unit 704 determines the temperature change rate in the box under the action of the constant output energy according to the basic energy balance equation of thermodynamics, that is, the basic energy balance equation of thermodynamics: , Among them, is the constant output energy (joule, J), is the mass of air (kilogram, kg), is the specific heat capacity of air (joule / kilogram·degree Celsius, J / kg·℃), is the temperature change rate in the box (degree Celsius, ℃). It should be noted that the mass of air can be determined according to the volume data of the electric energy metering box and the air density. Then, the temperature change simulation unit 704 sums the temperature change rate in the box and the heat dissipation efficiency to obtain the temperature change rate of the electric energy metering box when it is not in the heat dissipation state, and marks it as the simulated temperature change rate in the box.

[0125] The load adjustment calculation unit 706 is configured to determine a target current based on the simulated temperature change rate in the box and the heat dissipation coefficient, and then determine ideal load data of the corresponding line of the electric energy metering box based on the target current and voltage data, and adjust the load threshold of the overload protector according to the ideal load data.

[0126] Specifically, the load adjustment calculation unit 706 receives the heat dissipation coefficient determined by the line temperature calculation unit 406 included in the temperature data analysis module 400 and receives the simulated temperature change rate in the box determined by the temperature change simulation unit 704. The load adjustment calculation unit 706 determines the temperature difference according to the formula: , wherein is the simulated temperature change rate in the box under heat conduction, is the heat dissipation coefficient, and is the temperature difference of heat transfer. Then, the load adjustment calculation unit 706 determines the maximum output energy of the line in a safe state according to the basic energy balance equation of thermodynamics: , wherein is the maximum output energy (Joule, J), is the mass of air (kilogram, kg), is the specific heat capacity of air (Joule / kilogram·Celsius, J / kg·℃), is the temperature difference (Celsius, ℃).

[0127] Then, the load adjustment calculation unit 706 determines the target current of the maximum output energy of the line in a safe state based on the heat calculation formula, i.e., Joule's law: , wherein is the maximum output energy, is the target current, is the resistance, is the time. It should be noted that the resistance can be determined by dividing the voltage data by the current data of the corresponding line of the electric energy metering box, and the resistance is obtained. The time may be 1.

[0128] Finally, the load adjustment calculation unit 706 divides the voltage data of the corresponding line of the electric energy metering box by the target current to obtain the ideal load data of the corresponding line of the electric energy metering box. According to the calculated ideal load data, the load threshold of the overload protector is adjusted to ensure the safe operation of the system.

[0129] In the above power metering box early warning management system, the constant temperature calculation unit obtains constant output energy based on the judgment result and line safety temperature data, the temperature change simulation unit performs thermodynamic calculation based on the constant output energy and heat dissipation efficiency to obtain a simulated temperature change rate in the box, and the load adjustment calculation unit determines a target current based on the simulated temperature change rate in the box and heat dissipation coefficient, determines ideal load data of the corresponding line of the power metering box based on the target current and voltage data, and adjusts the load threshold of the overload protector according to the ideal load data, so as to dynamically adjust the load threshold of the overload protector, thereby optimizing the protection performance of the system under different temperature and load conditions, and effectively preventing faults or damage caused by overload.

[0130] In some embodiments, referring to Figure 5 , the power metering box early warning management system 100 further comprises:

[0131] The contrast statistical unit 802 is configured to statistically process the voltage data, the current data, the target temperature-in-box data, the ambient temperature data, the judgment result and the ideal load data to generate a load result contrast table.

[0132] Specifically, the contrast statistical unit 802 is signal-connected with the temperature-in-box processing module 102, the temperature-out-of-box ambient temperature acquisition module 104, the electric data monitoring and analyzing module 106, the load adjustment module 108 and the overload judgment module 500, and is configured to receive the target temperature-in-box data, the ambient temperature data, the voltage data, the current data, the judgment result and the ideal load data. The contrast statistical unit 802 comprehensively analyzes and statistically processes these data to generate the load result contrast table.

[0133] In some embodiments, the generation of the load result contrast table can also refer to historical data. The historical data is compared with the currently collected data to generate a preliminary load result contrast table. Whenever the system determines a new data correspondence relationship, the new added correspondence relationship is added to the load result contrast table to constantly update and optimize the load result contrast table, so as to ensure that the load result contrast table reflects the latest system state and load condition.

[0134] The contrast judgment unit 804 is configured to match the voltage data, the current data, the target temperature-in-box data and the ambient temperature data in the load result contrast table, determine the ideal load data of the corresponding line of the power metering box, and adjust the load threshold of the overload protector according to the ideal load data.

[0135] Specifically, the comparison and judgment unit 804 is connected with the box temperature processing module 102, the box environment temperature collection module 104, and the electric data monitoring and analysis module 106 in signal connection, for receiving the target box temperature data, the environment temperature data, the voltage data, and the current data. The comparison and judgment unit 804 is connected with the comparison and statistics unit 802 in signal connection. The comparison and judgment unit 804 queries whether there is corresponding data record in the load result comparison table for the target box temperature data, the environment temperature data, the voltage data, and the current data. If the matching record is found in the load result comparison table, the comparison and judgment unit 804 directly sends the adjustment instruction to the overload protector according to the ideal load data of the electric energy metering box corresponding line in the load result comparison table, so that the overload protector adjusts the load threshold according to the ideal load data.

[0136] In the above-mentioned electric energy metering box early warning management system, the comparison and statistics unit statistically processes the voltage data, the current data, the target box temperature data, the environment temperature data, the judgment result, and the ideal load data to generate the load result comparison table. In the application process, the comparison and judgment unit matches the voltage data, the current data, the target box temperature data, and the environment temperature data in the load result comparison table to determine the ideal load data of the electric energy metering box corresponding line, and adjusts the load threshold of the overload protector according to the ideal load data, thereby improving the stability and reliability of the system.

[0137] In some embodiments, the system is further configured to: in the case that no matching is found in the load result comparison table, determine the ideal load data.

[0138] Specifically, the voltage data, the current data, the target box temperature data, and the environment temperature data are matched with the load result comparison table. If no matching is found in the load result comparison table, further processing is required to ensure accurate load state judgment and ideal load data. Therefore, at this time, the overload judgment module 500 is required to analyze the current collected data to determine whether there is an overload phenomenon and to provide the corresponding judgment result. Based on the current judgment result and the collected data, the load adjustment module 108 calculates and determines an ideal load data to optimize the operating conditions and ensure the stability and efficiency of the electric energy metering box.

[0139] In the above-mentioned electric energy metering box early warning management system, in the case that no matching is found in the load result comparison table, the ideal load data is determined to improve the judgment efficiency.

[0140] In some embodiments, referring to Figure 6 , the electric energy metering box early warning management system 100 further comprises an alarm module 902 configured to output a corresponding alarm signal based on the judgment result.

[0141] Specifically, the alarm module 902 is connected with the overload judgment module 500, and receives the judgment result determined by the overload judgment unit 504 included in the overload judgment module 500. The judgment result includes two kinds of existence of overload phenomenon and non-existence of overload phenomenon. When the judgment result is "existence of overload phenomenon", the alarm module 902 will immediately trigger and output the corresponding alarm signal to warn the user that the system is overloaded. When the judgment result is "non-existence of overload phenomenon", the alarm module 902 will not generate the alarm signal, thereby maintaining the normal operation state of the system.

[0142] In the above-mentioned power metering box early warning management system, the alarm module outputs the corresponding alarm signal based on the judgment result, thereby improving the safety and stability of the power metering box.

[0143] The embodiments of the present specification provide a power metering box early warning management method, which is applied to any one of the above-mentioned power metering box early warning management systems. Please refer to Figure 7 The method can include the following steps:

[0144] S710, collecting the temperature in the power metering box, and processing the collected temperature data to obtain a temperature change curve in the box.

[0145] Specifically, the in-box temperature processing module is arranged in the power metering box to monitor the temperature change in the box. The in-box temperature processing module collects the temperature data in the power metering box through the temperature sensor at regular intervals. These temperature data record the temperature information at different time points. Then, the in-box temperature processing module arranges these temperature data in time sequence to form a time sequence. Based on the time sequence, the in-box temperature processing module draws a two-dimensional temperature change curve in the box.

[0146] S720, collecting the ambient temperature of the power metering box to obtain ambient temperature data.

[0147] S730, monitoring the electric data of the power metering box to obtain current data and voltage data.

[0148] Specifically, the out-of-box ambient temperature collection module is responsible for monitoring the ambient temperature outside the power metering box. The out-of-box ambient temperature collection module collects the out-of-box temperature data of the power metering box through the ambient temperature sensor in real time to obtain the ambient temperature data. The ambient temperature data are used to understand the temperature condition of the environment where the power metering box is located, so as to analyze the possible influence of the ambient temperature on the temperature in the box and the power metering system. The electric data monitoring and analyzing module is equipped with a current sensor and a voltage sensor, which are used to monitor the electrical parameters of the power metering box in real time to obtain the current data and the voltage data.

[0149] S740, based on the temperature change curve in the box, the environmental temperature data, the current data and the voltage data, determine the ideal load data of the corresponding line of the electric energy metering box, and adjust the load threshold of the overload protector according to the ideal load data.

[0150] Specifically, the load adjustment module is connected with the box temperature processing module, the external environment temperature acquisition module and the electric data monitoring and analysis module, and receives the temperature change curve in the box, the environmental temperature data, the current data and the voltage data. The load adjustment module comprehensively analyzes the collected data. Based on the temperature change curve in the box and the environmental temperature data, the load adjustment module determines the thermal environment of the electric energy metering box. In combination with the current and voltage data, the load adjustment module evaluates the actual state of the electrical load. Therefore, the load adjustment module uses the above data to consider the influence of temperature on the performance of electrical components, and calculates the ideal load data of the corresponding line of the electric energy metering box. According to the ideal load data calculated, the load threshold of the overload protector is adjusted to ensure that the overload protector can be disconnected in time when the load exceeds the safe range, thereby protecting the electric energy metering box and the internal equipment thereof.

[0151] In the above-mentioned electric energy metering box early warning management method, the electric energy metering box includes an overload protector. The electric energy metering box early warning management system includes a box temperature processing module, an external environment temperature acquisition module, an electric data monitoring and analysis module and a load adjustment module. First, the box temperature processing module collects the temperature in the electric energy metering box, processes the collected temperature data, and obtains the temperature change curve in the box. The external environment temperature acquisition module collects the environmental temperature of the electric energy metering box, and obtains the environmental temperature data. The electric data monitoring and analysis module monitors the electric data of the electric energy metering box, and obtains the current data and the voltage data. Then, the load adjustment module determines the ideal load data of the corresponding line of the electric energy metering box based on the temperature change curve in the box, the environmental temperature data, the current data and the voltage data, and adjusts the load threshold of the overload protector according to the ideal load data.

[0152] By collecting the temperature in the box and the external environment temperature, the temperature data of the corresponding line is determined. Since the effective load of the line changes with the change of temperature, the load adjustment module judges the maximum load of the line based on the temperature change curve in the box, the environmental temperature data, the current data and the voltage data, so that the preset load threshold in the overload protector can be adjusted in real time according to the current line state, thereby ensuring that the overload protector can accurately alarm the overload of the line and improving the accuracy and timeliness of the early warning result.
