Description

Technical Field

[0001] This invention relates to the field of electricity metering box technology, and in particular to an electricity metering box with an intelligent monitoring system. Background Technology

[0002] As the core metering equipment at the end of the power system, the electricity metering box is widely used in various scenarios such as residential buildings, commercial complexes, industrial plants, and public facilities. It undertakes the key responsibilities of accurate metering of electricity consumption and optimized allocation of power resources. Its metering accuracy and operational stability are directly related to the economic interests of power supply companies and users, and are also an important foundation for ensuring the efficient and safe operation of the power system.

[0003] Existing traditional electricity metering boxes lack effective environmental monitoring modules. During long-term operation, abnormal internal temperature and humidity can easily cause performance drift of metering components, leading to excessive electricity metering errors. Simultaneously, aging wiring and insulation decomposition within the metering box can generate harmful pollutants such as sulfides and dust, deteriorating air quality. These pollutants corrode metal terminals and contaminate insulating components, increasing contact resistance and reducing insulation performance. This not only further affects metering accuracy but may also trigger safety accidents such as short circuits and leakage. Furthermore, existing monitoring solutions often suffer from poor signal synchronization when multiple sensors work together, resulting in disordered monitoring data timing and affecting the accuracy of environmental condition assessments. Moreover, the complex electromagnetic environment in which the electricity metering box operates makes it susceptible to external electromagnetic interference that can intrude into the monitoring signal transmission path, causing signal distortion and reducing the reliability of the monitoring system.

[0011] The anomaly warning module is used to output an anomaly warning signal when the monitored data exceeds the dynamic calibration threshold or when the multi-parameter fusion judgment result is abnormal.

The metal shielding layer is connected to the grounding terminal of the box 1. The differential transmission circuit is set at the signal input terminal of the signal processing module to realize differential transmission of the monitoring signal.

[0055] Specifically, the dynamic calibration threshold of the data comparison module is constructed through an adaptive calibration algorithm and implemented in the following way: Dynamic calibration threshold construction: acquire air quality parameters, temperature and relative humidity data output by the signal processing module, and denote any parameter as x and parameter index as i; set the length of the historical data window as n, and establish an environmental parameter trend model based on the parameter monitoring data in the historical data window. The environmental parameter trend model fits the change law of the parameter over time through time series analysis method, providing data support for dynamic adjustment of the threshold. The acquisition time of the parameter in the historical data window is denoteed as k.

[0056] Through formula Calculate the dynamic calibration threshold; where This represents the dynamic calibration threshold of parameter x at time k. This represents the historical average value of parameter x from time n to k. , These represent the operating load rate (defined as the ratio of real-time load to rated load) at time k and the quantized value of the external environmental conditions (collected and quantified by external environmental sensors), respectively. This represents the basic safety threshold for parameter x, and its value conforms to power industry standards. These represent the weighting coefficients for historical data, operating load, and external environmental conditions, respectively. Then, multi-parameter weighted fusion calculation is used, through the formula: Obtain the comprehensive judgment value ;in, This represents the comprehensive judgment value at time k, where N represents the number of parameters. This represents the weight coefficient of the i-th parameter, which is specifically set based on the significance of the parameter's influence. This represents the detected value of the i-th parameter at time k. This represents the relative deviation of the i-th parameter, reflecting the degree of deviation between the detected value and the threshold.

[0057] Preset comprehensive parameter judgment threshold The judgment threshold corresponding to the parameter, if If the detected value of any parameter exceeds its corresponding dynamic calibration threshold, the environmental condition is determined to be abnormal; otherwise, the environmental condition is determined to be normal.

[0058] The working principle of this invention is as follows:

[0059] Preparation phase: Through the wire hole 8 on the mounting box 4, the staff connects the air quality sensor 7, temperature and humidity sensor 9 to the microcontroller 13 installed in the mounting slot 5 with wires to realize the circuit conduction of each component; then flip the sealing plate 3 hinged to the box door 2 to cover the opening of the mounting slot 5 to prevent dust and impurities from entering and affecting the operation of the components; at this time, the electromagnetic shielding coating on the inside of the protective box 6, the metal shielding layer on the signal transmission wire and the heat dissipation fins 11 are all in a standby state to ensure the stable operation of the system in the future.

[0060] Synchronous acquisition phase: The synchronization trigger unit of the intelligent monitoring system is activated, the clock synchronization module provides a unified clock reference, the trigger control circuit generates synchronization commands, and controls the air quality detection module and the temperature and humidity detection module to start working simultaneously. The air quality sensor 7 collects air quality parameters such as harmful gases, dust, and volatile organic compounds inside the enclosure 1 through the detection probe 10 that penetrates the mounting box 4; the temperature and humidity sensor 9 is stably installed through the snap-fit ​​slot of the fixing block 12 and synchronously collects temperature and relative humidity data inside the enclosure 1.

[0061] Signal processing stage: The collected air quality, temperature and humidity analog signals are transmitted through wires wrapped with metal shielding, and enter the signal processing module (integrated into microcontroller 13) through differential transmission circuit; the signal processing module filters and amplifies the signal in sequence to filter out interference caused by complex electromagnetic environment, and then converts the analog signal into digital signal to prepare for subsequent data comparison.

[0062] Data comparison stage: The data comparison module (integrated in the microcontroller 13) receives the processed digital signal, establishes an environmental parameter trend model based on the historical monitoring data of the power metering box, and dynamically adjusts the safety threshold of each parameter in combination with the current operating load, external environmental conditions and other factors. Then, according to the preset weight allocation rules, it comprehensively calculates the deviation of each parameter detection value from the corresponding dynamic threshold to determine whether the internal environmental state of the box 1 is normal.

[0063] Anomaly warning phase: If the data comparison results show that the environment is normal, the system continues to cycle through the above monitoring process; if the environment is determined to be abnormal (the comprehensive calculation result exceeds the standard or any parameter exceeds the corresponding dynamic threshold), the anomaly warning module is immediately activated, the remote signal transmission unit sends the warning information to the external monitoring terminal, and at the same time the local warning unit (LED light, buzzer) activates the on-site warning. After receiving the warning, the staff will go to the site in time to troubleshoot the fault until the environmental condition returns to normal.

[0064] Throughout the entire operation, the protective box 6 provides physical protection and electromagnetic shielding for the microcontroller 13, and the heat dissipation fins 11 quickly dissipate the heat generated by the microcontroller 13 during operation, ensuring that the intelligent monitoring system and all components operate stably and collaboratively, and realizing accurate monitoring and early warning of abnormalities in the internal environment of the power metering box.
