Description

Technical Field

[0001] This application relates to the technical field of electricity data acquisition, and in particular to a control method, system and storage medium for a dedicated transformer data acquisition terminal. Background Technology

[0002] The dedicated transformer data acquisition terminal control method refers to the process of controlling the power supply parameters of the charging power supply and the supercapacitor to ensure that the dedicated transformer data acquisition terminal is powered during the power failure period and to ensure that the dedicated transformer data acquisition terminal is working normally when a power supply failure occurs.

[0003] In related technologies, when a power supply failure occurs in the dedicated transformer data acquisition terminal and a supercapacitor and charging power supply are needed for temporary power supply, the supercapacitor first responds to the fault instantaneously and provides emergency power to the dedicated transformer data acquisition terminal during the startup time of the charging power supply. After the charging power supply is started, it switches to the charging power supply for continuous power supply and charges the supercapacitor and charging power supply after the power supply is restored.

[0004] Regarding the aforementioned technologies, when temporarily powering the dedicated transformer data acquisition terminal using a supercapacitor and a charging power supply, the supercapacitor and backup power supply operate according to a fixed switching mode. This can lead to insufficient power in the charging power supply, preventing continued power supply to the dedicated transformer data acquisition terminal. Furthermore, when charging the long-term depleted supercapacitor after power restoration, the circuit uses a fixed power to charge the supercapacitor, resulting in a sudden surge of high current. This reduces the supercapacitor's lifespan and affects the stability of the dedicated transformer data acquisition terminal, indicating room for improvement. Summary of the Invention

[0059] A computer-readable storage medium storing a computer program that can be loaded by a processor and executed by any of the above-described special transformer data acquisition terminal control methods.

[0060] In summary, this application includes at least one of the following beneficial technical effects:

[0061] 1. By determining whether the terminal power supply is within the normal power supply range, it can be determined whether the dedicated transformer processing terminal has experienced a power supply failure. When the terminal power supply is within the normal power supply range, it indicates that the dedicated transformer data acquisition terminal has not experienced a failure. Therefore, the remaining power of the capacitor and the remaining power of the rechargeable battery are obtained, and the supercapacitor and rechargeable battery are charged according to the remaining power to ensure sufficient emergency power. When the terminal power supply is outside the normal power supply range, the historical operation log of the dedicated transformer data acquisition terminal is obtained, and the power supply parameters of the supercapacitor and rechargeable battery are controlled according to the historical operation log, thereby ensuring that the supercapacitor and rechargeable battery provide stable power to the dedicated transformer processing terminal and improving the stability of the power supply to the dedicated transformer data acquisition terminal.

[0062] 2. By obtaining the current power outage period, the system searches the historical operation log for the corresponding historical power outage duration based on the current power outage period. The power outage duration is then fuzzily estimated and divided based on the fuzzy duration data to determine the fuzzy duration probability and fuzzy power outage time. The fuzzy power outage duration is then weighted based on the fuzzy power outage probability to determine the predicted power outage duration. Thus, the power outage time is estimated based on historical data. Furthermore, based on the predicted power outage time, the system controls the supercapacitor and rechargeable battery to provide temporary power to the dedicated transformer acquisition terminal, thereby optimizing the power supply effect of the supercapacitor and rechargeable battery.

[0063] 3. By determining whether the power supply usage time of the charging power source is greater than the predicted power outage duration, it can be determined whether the power supply time of the supercapacitor needs to be extended. When the power supply usage time is greater than the predicted power outage duration, it indicates that the current charging power source has sufficient power and there is no need to extend the power supply time of the supercapacitor. Therefore, the power supply start-up time is determined as the capacitor power supply time. When the charging power source starts, the supercapacitor power supply can be stopped. When the power supply usage time is less than the predicted power outage time, it indicates that the charging power source has insufficient power and the supercapacitor power supply time needs to be extended. Therefore, the quotient of the available power of the capacitor and the capacitor power consumption rate is calculated to determine the capacitor power supply time. Thus, when the charging power source has insufficient power, the supercapacitor is controlled to supply power to the dedicated transformer acquisition terminal for the maximum allowable power supply time, thereby extending the working time of the supercapacitor and the backup power source.

Detailed Implementation

[0071] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figures 1 to 7 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0072] This application discloses a control method, system, and storage medium for a dedicated transformer data acquisition terminal. Specifically, it discloses a processing terminal and a dedicated transformer data acquisition terminal. The processing terminal and the dedicated transformer data acquisition terminal are communicatively connected to achieve information interaction and control. The processing terminal obtains the terminal's power supply power and determines whether the terminal's power supply power is within the normal power supply range, thereby determining whether the dedicated transformer processing terminal has experienced a power supply fault. When the terminal's power supply power is within the normal power supply range, it indicates that the dedicated transformer data acquisition terminal has not experienced a fault. Therefore, the remaining power of the supercapacitor and the rechargeable battery are obtained, and the supercapacitor and rechargeable battery are charged according to the remaining power to ensure sufficient emergency power. When the terminal's power supply power is outside the normal power supply range, the historical operation log of the dedicated transformer data acquisition terminal is obtained, and the power supply parameters of the supercapacitor and rechargeable battery are controlled according to the historical operation log, thereby ensuring that the supercapacitor and rechargeable battery provide stable power to the dedicated transformer processing terminal and improving the stability of the dedicated transformer data acquisition terminal's power supply.

[0073] Reference Figure 1This application discloses a control method for a dedicated transformer data acquisition terminal, comprising the following steps:

[0074] Step S100: Obtain the terminal power supply of the preset dedicated transformer acquisition terminal.

[0075] The dedicated transformer data acquisition terminal refers to a data acquisition device deployed on a transformer within a power system. It is primarily used to collect real-time electricity consumption data such as voltage, current, power, and energy from the user side of the dedicated transformer, monitor the power grid's supply status and its own operating conditions, upload the data to the power supply master station, and respond to command signals from the master station. The dedicated transformer data acquisition terminal consists of a power conversion module, display module, communication module, input module, keypad module, output module, metering module, and storage module. The remote signaling input module and gate contact input module have voltage isolation functions, enabling AC 4kV withstand voltage. A TVS (Transient Voltage Suppressor) is added to the remote signaling input side to protect the electronic circuitry from transient high voltage, achieving overvoltage protection and increasing the reliability of the electronic circuitry. The dedicated transformer data acquisition terminal has six communication modes, including remote communication and Ethernet communication, improving the communication stability of the dedicated transformer data acquisition terminal.

[0076] Terminal power supply refers to the input power supply of the dedicated transformer data acquisition terminal, which is determined by the processing terminal based on the pulse signal from the AC sampling device or energy meter built into the dedicated transformer data acquisition terminal in real time.

[0077] Step S101: Determine whether the terminal power supply is within the preset normal power supply range.

[0078] The normal power supply range refers to the range of input power that the dedicated transformer data acquisition terminal can operate normally, which is determined by the operator based on the equipment parameters of the dedicated transformer data acquisition terminal and the grid demand.

[0079] By processing the terminal to determine whether the terminal power supply is within the normal power supply range, it can be determined whether there is a power supply abnormality in the dedicated transformer data acquisition terminal, thereby monitoring the power supply status of the dedicated transformer data acquisition terminal in real time and improving the power supply stability of the dedicated transformer data acquisition terminal.

[0080] Step S1011: If yes, then obtain the remaining power of the preset supercapacitor and the remaining power of the preset rechargeable battery.

[0081] If the processing terminal determines that the terminal power supply is within the normal power supply range, it indicates that the power supply of the dedicated transformer acquisition circuit is normal at this time. There is no need to call the supercapacitor and charging power supply to temporarily power the dedicated transformer acquisition equipment. Therefore, the remaining power of the capacitor and the power of the charging battery are obtained to provide data support for the subsequent control of the dedicated transformer acquisition terminal to charge the supercapacitor and the charging battery, thereby ensuring the power supply stability of the supercapacitor and the charging power supply.

[0082] A supercapacitor is a novel energy storage element that uses double-layer electrical contacts, falling between a capacitor and a battery. It is used to rapidly supply power to the circuit when a power supply anomaly occurs at the dedicated transformer data acquisition terminal, based on the capacitor's discharge characteristics. A rechargeable battery is a backup power source that provides temporary power to the circuit when a power supply anomaly occurs at the dedicated transformer processing terminal. The charging voltage of a rechargeable battery is the same as that of a supercapacitor, preventing overcharging of the supercapacitor and thus extending its lifespan.

[0083] The remaining charge of the capacitor refers to the remaining reserve charge of the supercapacitor. It is determined by the processing terminal through the supercapacitor data collection terminal via the dedicated transformer equipment, and then by the capacitor charge calculation formula.

[0084] The remaining battery capacity refers to the remaining reserve capacity of the rechargeable battery. It is determined by the processing terminal through the SOC algorithm after collecting data from the charging power supply of the data acquisition terminal of the dedicated transformer.

[0085] Step S1012: Based on the remaining power of the capacitor and the remaining power of the battery, control the dedicated transformer acquisition terminal to charge the supercapacitor and the rechargeable battery, and continue to acquire the terminal power supply for cyclic judgment.

[0086] After determining the remaining power of the capacitor and battery, the dedicated transformer data acquisition terminal controls its charging via its built-in core board. The core board controls the charging time of the supercapacitor and rechargeable battery. When the power level falls below a set value, it enables the power chip, allowing the rechargeable battery to charge. Conversely, when the power level rises above the set value, it disables the power chip, stopping the battery charging. Simultaneously, it continuously acquires the terminal's power supply power for cyclical calculations, thereby monitoring the power supply status of the dedicated transformer data acquisition terminal in real time and improving its power supply stability.

[0087] Step S1013: If not, obtain the historical operation log of the dedicated transformer acquisition terminal.

[0088] If the processing terminal determines that the terminal power supply is not within the normal power supply range, it indicates that the dedicated transformer acquisition terminal is experiencing a power supply abnormality and a power outage. Therefore, the historical operation log of the dedicated transformer acquisition terminal is obtained to provide data support for subsequent determination of the predicted power outage time, thereby improving the accuracy of power supply control for supercapacitors and charging power supplies.

[0089] Step S1014: Analyze the historical operation logs to control the supercapacitor and rechargeable battery to provide temporary power to the dedicated transformer acquisition terminal.

[0090] After determining the historical operation logs, these logs are analyzed to control the temporary power supply of the supercapacitor and rechargeable battery to the dedicated transformer data acquisition terminal, thereby improving the stability of the terminal. Specific analysis steps are detailed below. Figure 2 The steps in the process.

[0091] Reference Figure 2 The steps for analyzing historical operation logs to control the temporary power supply of supercapacitors and rechargeable batteries to the dedicated transformer data acquisition terminal include:

[0092] Step S200: Obtain the power outage period.

[0093] The power outage period refers to the power outage period of the dedicated transformer data acquisition terminal, such as from 2 pm to 4 pm. After the processing terminal obtains the current power outage time, it determines the time period in which the current power outage time is located according to the time period division rules.

[0094] Step S201: Search the historical operation log according to the power outage period to determine the historical power outage duration corresponding to the power outage period.

[0095] Among them, the historical power outage duration refers to the duration of power outages that occur during the power outage period in the historical operation log. It is determined by the processing terminal by searching for equipment power outages during the same period in the historical operation log through the power outage period.

[0096] Step S202: Determine the fuzzy duration probability and fuzzy power outage time of the historical power outage based on the preset fuzzy duration value.

[0097] Among them, the fuzzy duration value refers to the duration value after rounding up and fuzzing the specific power outage duration. For example, the fuzzy duration data is in units of 10. If the historical power outage duration is 34 minutes, then the historical power outage duration will be fuzzed to 40 minutes, thereby improving the concentration of reference data and improving judgment efficiency. It is determined by the operator based on the power supply requirements of the special transformer acquisition terminal and the relative power supply of the supercapacitor and the charging power supply.

[0098] Fuzzy power outage time refers to the power outage duration after fuzzy duration value processing, which is determined by the processing terminal by rounding up the historical power outage duration based on the fuzzy duration value.

[0099] The fuzzy duration probability refers to the relative probability corresponding to all fuzzy power outage times in the historical operation log. After determining the fuzzy power outage time, the processing terminal integrates all the fuzzy power outage times, determines the number of times each fuzzy power outage time occurs, and then calculates the probability of the number of occurrences.

[0100] Step S203: Weight the fuzzy power outage time according to the fuzzy power outage probability to determine the predicted power outage duration.

[0101] Among them, the predicted power outage duration refers to the predicted power outage duration of the dedicated transformer data acquisition terminal. After determining all fuzzy power outage times and their corresponding fuzzy power outage probabilities, the processing terminal weights the fuzzy power outage times with the fuzzy power outage probabilities and finally determines the expected value of the power outage time, which is the predicted power outage duration. This improves the accuracy of historical reference data and thus enhances the stability of the power supply to the dedicated transformer data acquisition terminal.

[0102] Step S204: Analyze the predicted power outage duration and historical operation logs to control the supercapacitor and rechargeable battery to provide temporary power to the dedicated transformer acquisition terminal.

[0103] The process involves determining the predicted power outage duration, analyzing the predicted outage duration and historical operation logs, and controlling the supercapacitor and rechargeable battery to provide temporary power to the dedicated transformer data acquisition terminal. Specific analysis steps are detailed below. Figure 3 The steps in the process.

[0104] Reference Figure 3 The steps for analyzing predicted power outage duration and historical operation logs to control the temporary power supply of supercapacitors and rechargeable batteries to the dedicated transformer data acquisition terminal include:

[0105] Step S300: Extract data from historical operation logs to determine the power consumption rate.

[0106] Among them, the power consumption rate refers to the rate at which the power is consumed when the dedicated transformer acquisition terminal is powered by the charging power supply. It is determined by the processing terminal by extracting the charging power supply data from the historical operation log.

[0107] Step S301: Obtain the current power level.

[0108] The current power level is consistent with the remaining battery power in step S1011, and is determined by the processing terminal through the charging power data collected by the dedicated transformer acquisition terminal.

[0109] Step S302: Calculate the quotient of the current power level and the power consumption rate to determine the power usage time.

[0110] Among them, the power usage time refers to the power supply time that the charging power supply can provide power to the dedicated transformer data acquisition terminal under the current power level, which is determined by the processing terminal by calculating the quotient of the current power level and the power consumption rate.

[0111] Step S303: Analyze historical operation logs, power usage time, and predicted power outage duration to determine capacitor power supply time.

[0112] The capacitor power supply time refers to the duration during which the capacitor is powered on. This time is determined by the processing terminal through analysis of historical operation logs, power usage time, and predicted power outage duration. Specific analysis steps are detailed below. Figure 4 The steps in the process.

[0113] Step S304: Analyze the capacitor power supply time, historical operation log, current power supply level and expected power outage duration to control the supercapacitor and rechargeable battery to provide temporary power to the dedicated transformer acquisition circuit.

[0114] After determining the capacitor power supply time, the capacitor power supply time, historical operation logs, current power supply level, and estimated power outage duration are analyzed to control the supercapacitor and rechargeable battery to provide temporary power to the dedicated transformer acquisition circuit. Specific analysis steps are detailed below. Figure 5 The steps in the process.

[0115] Reference Figure 4 The steps for determining capacitor power supply time by analyzing historical operation logs, power usage time, and predicted power outage duration include:

[0116] Step S400: Determine whether the power usage time is greater than the predicted power outage duration.

[0117] Specifically, by processing the terminal to determine whether the power usage time is greater than the predicted power outage duration, it can be determined whether the charging power supply can stably supply power to the dedicated transformer data acquisition terminal within the predicted power outage time. Then, based on the power usage time, the power supply parameters of the charging power supply and supercapacitor are determined to improve the stability of the dedicated transformer data acquisition terminal.

[0118] Step S401: If it is greater than the preset power-on time, then the preset power-on time is determined as the capacitor power supply time.

[0119] If the processing terminal determines that the power usage time is longer than the predicted power outage duration, it indicates that the charging power supply is sufficient to temporarily power the dedicated transformer acquisition terminal during the predicted power outage time. Therefore, the power start-up time is determined as the capacitor power supply time.

[0120] Power start-up time refers to the maximum start-up response time of the charging power supply, which is determined by the operator by combining the characteristics of the dedicated transformer acquisition terminal with the response test results of the backup power supply.

[0121] Step S402: If it is not greater than, then obtain the current capacitor charge.

[0122] If the processing terminal determines that the power usage time is not greater than the predicted power outage duration, it indicates that the charging power supply is insufficient and cannot provide temporary power to the dedicated transformer data acquisition terminal within the predicted power outage time. Therefore, the current capacitor power is obtained, and the capacitor power supply time is determined based on the current capacitor power, thereby extending the temporary power supply time of the supercapacitor and the charging power supply and improving the power supply stability of the dedicated transformer data acquisition equipment.

[0123] Step S403: Calculate the difference between the current capacitor charge and the preset minimum capacitor charge to determine the available capacitor charge.

[0124] The minimum capacitor charge refers to the minimum safe charge of the supercapacitor, which is determined by the operator by combining the component characteristics of the supercapacitor with the circuit characteristics of the dedicated transformer data acquisition terminal.

[0125] The available capacity of the capacitor refers to the maximum safe power supply that the supercapacitor can provide for temporary power to the dedicated transformer data acquisition terminal. It is determined by the processing terminal by calculating the difference between the current capacitor capacity and the minimum capacitor capacity, providing data support for determining the capacitor power supply time.

[0126] Step S404: Extract data from historical operation logs to determine the capacitor power consumption rate.

[0127] Among them, the capacitor power consumption rate refers to the power consumption rate when the supercapacitor provides temporary power to the dedicated transformer acquisition circuit, which is determined by the processing terminal by extracting the supercapacitor power supply data from the historical operation log.

[0128] Step S405: Calculate the quotient of the available charge of the capacitor and the rate of charge consumption of the capacitor to determine the capacitor power supply time.

[0129] The capacitor power supply time is the same as the capacitor power supply time in step S303, and is determined by the processing terminal by calculating the quotient of the available capacitor power and the capacitor power consumption rate.

[0130] Reference Figure 5 The steps for controlling the temporary power supply of the supercapacitor and rechargeable battery to the dedicated transformer acquisition circuit, based on analysis of capacitor power supply time, historical operation logs, current power level, and estimated power outage duration, include:

[0131] Step S500: Determine whether the capacitor power supply time is greater than the preset power response time.

[0132] The power response time is the same as the power start-up time in step S401, which is the time it takes for the charging power supply to respond to the power supply command.

[0133] By processing the terminal to determine whether the capacitor power supply time is greater than the power supply response time, it can be determined whether the charging power supply is sufficient and whether the supercapacitor provides compensatory power to the dedicated transformer acquisition circuit. Based on the power supply method of the supercapacitor, the power supply method of the charging power supply can be further determined, thereby improving the stability of the dedicated transformer acquisition terminal.

[0134] Step S501: If it is greater than the specified value, then control the supercapacitor to provide temporary power to the dedicated transformer acquisition terminal according to the capacitor power supply time.

[0135] If the processing terminal determines that the capacitor power supply time is longer than the power supply response time, it indicates that the charging power supply is insufficient and the supercapacitor needs to provide compensatory power. Therefore, the supercapacitor is first controlled to provide temporary power to the dedicated transformer acquisition terminal based on the capacitor power supply time, so as to provide data support for the subsequent control of the charging power supply to provide temporary power to the dedicated transformer acquisition circuit.

[0136] Step S502: Obtain the current capacitor voltage.

[0137] The current capacitor voltage refers to the voltage value of the supercapacitor after it supplies power to the dedicated transformer acquisition circuit according to the capacitor power supply time. It is determined by the processing terminal after the supercapacitor power supply ends by retrieving the supercapacitor acquisition data from the dedicated transformer acquisition device.

[0138] Step S503: Calculate the difference between the predicted power outage time and the capacitor power supply time to determine the remaining power outage time.

[0139] The remaining power supply time refers to the remaining power outage time after the supercapacitor supplies power to the dedicated transformer acquisition terminal. It is determined by the processing terminal by calculating the difference between the predicted power outage time and the capacitor power supply time.

[0140] Step S504: Analyze the current capacitor voltage, historical operation log, current power supply level, and remaining power outage time to control the rechargeable battery to provide temporary power to the dedicated transformer acquisition circuit.

[0141] After determining the remaining power supply time, the current capacitor voltage, historical operation logs, current power supply level, and remaining power outage time are analyzed to control the rechargeable battery to provide temporary power to the dedicated transformer's data acquisition circuit. Specific analysis steps are detailed below. Figure 6 The steps in the process.

[0142] Step S505: If it is not greater than, then control the supercapacitor to supply power to the dedicated transformer acquisition terminal during the capacitor power supply time, and then use the charging power supply to temporarily supply power to the dedicated transformer acquisition terminal.

[0143] If the processing terminal determines that the capacitor power supply time is not greater than the power supply response time, it indicates that the charging power supply is sufficient and there is no need for the supercapacitor to provide compensatory power to the dedicated transformer data acquisition terminal. The supercapacitor power supply will not be too low. Therefore, the supercapacitor is controlled to supply power to the dedicated transformer data acquisition terminal during the capacitor power supply time, and then the charging power supply is used to temporarily supply power to the dedicated transformer data acquisition terminal.

[0144] Reference Figure 6 The steps for analyzing the current capacitor voltage, historical operating logs, current power supply level, and remaining power outage time to control the rechargeable battery to provide temporary power to the dedicated transformer's data acquisition circuit include:

[0145] Step S600: Calculate the product of the preset standard power supply and the remaining power outage time to determine the power consumption.

[0146] The standard power supply refers to the standard input power of the dedicated transformer data acquisition terminal, which is determined by the operator based on the equipment structure requirements of the dedicated transformer data acquisition terminal.

[0147] Power consumption refers to the amount of electricity required for the dedicated transformer data acquisition terminal to operate normally during the remaining power outage time. It is determined by the processing terminal by calculating the product of the standard power supply and the remaining power outage time, providing data support for subsequent determination of power redundancy.

[0148] Step S601: Calculate the product of the current power supply and the preset power conversion efficiency to determine the current power supply.

[0149] Among them, the power conversion efficiency refers to the actual power supply efficiency of the charging power supply after removing losses such as heat energy. It is determined by the operator through actual measurement of the charging power supply in each stage and the integration and calculation of the data.

[0150] The current power supply refers to the effective amount of electricity that the charging power can actually be used to temporarily supply the dedicated transformer data acquisition terminal after removing losses. It is determined by the processing terminal by calculating the product of the current power supply and the preset power conversion efficiency.

[0151] Step S602: Calculate the difference between the current power supply and the power consumption of the power supply to determine the power supply redundancy.

[0152] Among them, the power redundancy refers to the remaining effective power after the charging power supply provides temporary power to the dedicated transformer acquisition terminal during the remaining power supply time. It is determined by the processing terminal by calculating the difference between the current power supply and the power consumption.

[0153] Step S603: Calculate the quotient of power redundancy and power conversion efficiency to determine battery redundancy supply.

[0154] Among them, battery redundancy supply refers to the actual remaining power after the charging power supply provides temporary power to the dedicated transformer data acquisition terminal during the remaining power supply time. It is determined by the processing terminal by calculating the ratio of power redundancy power and power conversion efficiency.

[0155] Step S604: Input the current capacitor voltage, the preset maximum capacitor voltage, and the preset nominal capacitor capacity into the preset capacitor charging model to determine the full charge capacity.

[0156] The maximum voltage of the capacitor refers to the upper limit of the voltage of the supercapacitor. The operator determines the specific voltage data according to the supercapacitor parameter manual and then directly inputs the relevant data into the system.

[0157] The nominal capacitance refers to the standard capacitance rating. The operator determines the specific capacitance data according to the supercapacitor parameter manual and then directly inputs the relevant data into the system.

[0158] A capacitor charging model is a model used to calculate the amount of charge required to raise the voltage of a supercapacitor from its current value to a target voltage value.

[0159] Full charge capacity refers to the amount of charge required to fully charge a supercapacitor. This is determined by the processing terminal by inputting the current capacitor voltage, maximum capacitor voltage, and nominal capacitor capacity into the capacitor charging model. The specific calculation formula is as follows:

[0160] .

[0161] In the formula, To fully charge the battery, For the current capacitor current, This is the maximum voltage across the capacitor. This refers to the nominal capacitance of the capacitor.

[0162] Step S605: Input the current capacitor voltage, the preset safe capacitor voltage, and the nominal capacitor capacity into the capacitor charging model to determine the safe charging capacity.

[0163] Among them, the safety capacitor voltage refers to the minimum safe voltage of the capacitor. The operator determines the specific voltage data according to the supercapacitor parameter manual and then directly inputs the relevant data into the system.

[0164] Safe charging capacity refers to the amount of charging power required to maintain the supercapacitor's voltage at the minimum safe voltage. It is determined by the processing terminal by inputting the current capacitor voltage, the safe capacitor voltage, and the nominal capacitor capacity into the capacitor charging model. The specific calculation formula is as follows:

[0165] .

[0166] In the formula, For safe charging power, This is the current capacitor voltage. For safe capacitor voltage, This refers to the nominal capacitance of the capacitor.

[0167] Step S606: Analyze the full charge capacity, safe charge capacity, remaining power outage time, and power redundancy capacity to control the rechargeable battery to provide temporary power to the dedicated transformer acquisition circuit.

[0168] After determining the safe charging capacity and the full charging capacity, the full charging capacity, safe charging capacity, remaining power outage time, and power redundancy are analyzed to control the rechargeable battery's temporary power supply to the dedicated transformer's data acquisition circuit. Specific analysis steps are detailed below. Figure 7 The steps in the process.

[0169] Reference Figure 7 The steps for analyzing the full charge capacity, safe charging capacity, remaining power outage time, and power redundancy to control the temporary power supply of the rechargeable battery to the dedicated transformer acquisition circuit include:

[0170] Step S700: Determine whether the power supply redundancy is greater than the full charge capacity.

[0171] The system determines whether the power supply redundancy is greater than the full charge capacity by processing the terminal. Based on the power supply redundancy, it determines the charging power when the power supply charges the dedicated transformer data acquisition terminal. This avoids charging the depleted supercapacitor with a fixed power after the dedicated transformer data acquisition terminal is restored, thus preventing current overshoot and improving the service life of the dedicated transformer processing terminal.

[0172] Step S701: If it is greater than, calculate the power of the full charge and the power of the remaining power outage time to determine the capacitor charging power.

[0173] If the processing terminal determines that the power supply redundancy is greater than the full charge capacity, it indicates that the power supply is sufficient and the supercapacitor can be charged according to the maximum charging power of the super power supply. Therefore, the power of the full charge capacity and the power of the remaining power outage time are calculated to determine the capacitor charging power.

[0174] The capacitor charging power refers to the charging power of the supercapacitor after the charging capacitor supplies power to the dedicated transformer acquisition terminal. It is determined by the processing terminal when the power supply redundancy is greater than the full charge capacity by calculating the power of the full charge capacity and the remaining power outage time, or when the power supply redundancy is not greater than the full charge capacity by calculating the power of the safe charging power and the remaining power outage time.

[0175] Step S702: If it is not greater than, calculate the safe charging power and the power of the remaining power-off time to determine the capacitor charging power.

[0176] If the processing terminal determines that the power supply redundancy is not greater than the full charge capacity, it indicates that the power supply is insufficient and cannot charge the supercapacitor according to the maximum charging power of the super power supply. Therefore, the safe charging power and the power of the remaining power outage time are calculated to ensure that the supercapacitor is in a safe state when the dedicated transformer acquisition terminal restores power, thereby extending the service life of the supercapacitor.

[0177] Step S703: Control the charging power supply to temporarily power the dedicated transformer data acquisition terminal, and charge the supercapacitor with the capacitor charging power.

[0178] In this process, after determining the capacitor charging power, the charging power supply is controlled to temporarily power the dedicated transformer data acquisition terminal, and the supercapacitor is charged using the capacitor charging power.
