Description

Technical Field

[0001] This invention relates to the field of metering box monitoring technology, specifically to an outdoor floor-standing metering box and its safety control system for environmental early warning. Background Technology

[0002] Outdoor floor-mounted metering boxes, as key metering and distribution equipment at the end of the power system, are widely used in urban transformer substations, rural power distribution networks, and industrial parks. They are exposed to complex environments such as high temperatures, heavy rain, lightning, sandstorms, and ground subsidence for extended periods, facing multiple hidden dangers such as aging of the box structure, electrical component failures, and human-caused damage. The operational safety of outdoor floor-mounted metering boxes directly determines the accuracy of power metering, the stability of power supply, and the safety of surrounding personnel and equipment.

[0003] For example, Chinese invention patent CN118670459A discloses an "Intelligent Early Warning System for the Operating Environment of an Outdoor Power Metering Box". This system is constructed by building a detection module, an internal operating environment analysis module, an external operating environment analysis module, an early warning terminal, and a cloud database. It can collect environmental parameters such as internal temperature and humidity, external rainfall, and wind speed in real time, and trigger early warnings through correlation analysis of internal and external environmental data. The system aims to reduce the frequency of manual inspections and lower maintenance costs.

[0004] However, the monitoring dimensions of the above-mentioned technical solutions only focus on the environmental level, lacking the supervision of the enclosure structure and core electrical parameters. They judge anomalies solely by comparing environmental parameters with preset thresholds, without considering the coupled influence of environmental, structural and electrical parameters. At the same time, they do not design a graded maintenance mechanism based on the level of hidden danger. The protection strategy is only at the level of early warning and reminder, which is not conducive to achieving comprehensive, accurate and intelligent safety supervision of outdoor ground-mounted metering boxes, and it is difficult to significantly improve the operational safety and stability of metering boxes in complex outdoor environments.

[0005] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide an outdoor floor-standing metering box for environmental early warning and its safety control system, so as to solve the technical defects mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a safety control system for an outdoor floor-mounted metering box for environmental early warning, comprising an environmental multi-dimensional sensing module, a box structure analysis module, an electrical parameter monitoring module, a hidden danger decision-making and classification module, a linkage and maintenance module, a protection hidden danger early warning module, and a power emergency monitoring center; The multi-dimensional environmental sensing module collects physical quantities of the internal and external environment of the enclosure and its surroundings; the enclosure structure analysis module monitors the enclosure structure; the electrical parameter monitoring module monitors the internal electrical system; the hazard decision-making and grading module classifies hazard levels based on comprehensive hazard decision values; the linkage and control module issues control commands to execute safety protection according to the hazard level; the protection hazard early warning module analyzes the hazards of the actuators and generates alarm signals; and the power emergency monitoring center receives the data and realizes centralized monitoring and emergency linkage.

[0008] Furthermore, the hazard decision-making and grading module integrates environmental, enclosure structure, and electrical data in a spatiotemporal alignment, calculates the environmental hazard coefficient, enclosure structure hazard coefficient, and electrical parameter hazard coefficient respectively, obtains the comprehensive hazard decision value through a weighted formula, and classifies hazards into four levels: low, medium, high, and extremely high.

[0009] Furthermore, the environmental hazard coefficient is calculated by weighting the normalized hazard values ​​of the temperature and humidity difference between the inside and outside of the enclosure, the atmospheric pressure difference, rainfall, wind speed, lightning induction intensity, enclosure vibration amplitude, and ground settlement, combined with various environmental weighting coefficients.

[0010] Furthermore, the structural hazard coefficient of the enclosure is calculated by weighting the normalized hazard values ​​of door panel displacement, abnormal lock status, sealing strip pressure difference, enclosure frame strain, and bolt preload difference, combined with various structural weight coefficients.

[0011] Furthermore, the electrical parameter hazard coefficient is calculated by weighting the normalized hazard values ​​of the difference between incoming and outgoing line currents, the difference between incoming and outgoing line voltages, the power factor deviation, the leakage current, and the component temperature rise, combined with the electrical anomaly classification coefficient and various electrical weight coefficients.

[0012] Furthermore, the linkage and maintenance module implements a tiered maintenance strategy according to low, medium, high, and extremely high hazard levels; the protection hazard early warning module calculates the execution hazard coefficient based on the execution risk value and execution delay value of the executing agency, marks the hazard agency, and generates a protection hazard alarm signal to be pushed to the power emergency monitoring center.

[0013] Furthermore, the present invention also proposes an outdoor floor-standing metering box for environmental early warning, which adopts the aforementioned safety control system for the outdoor floor-standing metering box for environmental early warning.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by comprehensively collecting the internal and external environment, box structure and core electrical parameters and accurately calculating the comprehensive hidden dangers of outdoor floor-standing metering boxes, the false omission rate is reduced. Furthermore, a tiered maintenance strategy is implemented according to the level of hidden dangers to improve the pertinence and effectiveness of protection. This achieves comprehensive, precise and intelligent safety supervision of outdoor floor-standing metering boxes, significantly reducing equipment failure and safety accident losses, and meeting the long-term supervision needs of outdoor floor-standing metering boxes.

[0015] 2. In this invention, the protection hazard early warning module analyzes the degree of protection hazards for outdoor floor-standing meter boxes during the detection period. When a protection hazard alarm signal is generated, it reminds the management personnel to take corresponding improvement measures to ensure the efficient and stable operation of all actuators, further strengthen the safety protection line for outdoor floor-standing meter boxes, and reduce the difficulty of safety supervision for outdoor floor-standing meter boxes by management personnel. Attached Figure Description

[0016] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings; Figure 1 This is a system block diagram of Embodiment 1 of the present invention; Figure 2 This is a system block diagram of Embodiment 2 of the present invention. Detailed Implementation

[0017] Example 1: As Figure 1 As shown, the safety control system for outdoor floor-mounted metering boxes for environmental early warning proposed in this invention includes an environmental multi-dimensional sensing module, a box structure analysis module, an electrical parameter monitoring module, a hidden danger decision-making and classification module, a linkage and maintenance module, and a power emergency monitoring center. The multi-dimensional environmental sensing module collects multiple environmental physical quantities in real time from inside, outside and around the outdoor floor-standing metering box. After conditioning, converting and standardizing the collected signals, it outputs standardized environmental sensing data without redundancy or interference, providing comprehensive environmental basic data for quantifying hazard decision-making. Specifically, the multi-dimensional environmental sensing module uses temperature, humidity, and atmospheric pressure sensors inside the outdoor floor-standing metering box, and rain, wind speed, lightning strike intensity, and corrosive gas concentration sensors outside the box. Vibration and settlement sensors are also placed around the box to simultaneously collect 10 environmental physical quantities, including the temperature T1 inside the box, the humidity H1 inside the box, the temperature T2 outside the box, the humidity H2 outside the box, atmospheric pressure P, rainfall R, real-time wind speed V, lightning strike intensity L, box vibration amplitude A, and ground settlement S1. Each sensor transmits the collected analog electrical signals to the built-in signal conditioning circuit in real time, which sequentially performs low-pass filtering, signal amplification and noise suppression to eliminate electromagnetic and mechanical interference in the outdoor environment. The conditioned analog signals are then converted into digital signals by a high-precision A / D conversion module. Furthermore, through the built-in standardized processing unit, based on the "Specification for Environmental Monitoring Data of Power Metering Equipment", each digital signal is converted into standardized environmental data with unified dimensions and a value range of [0,1]. At the same time, the built-in data verification unit removes invalid, duplicate and abnormal data. Finally, the standardized environmental sensing data is transmitted in real time to the hidden danger decision-making and classification module through Bluetooth Mesh + 4G / 5G dual communication architecture.

[0018] The enclosure structure analysis module collects and extracts features from the mechanical structure status parameters of the outdoor floor-standing metering box, completes intelligent analysis and anomaly marking of the enclosure structure status, and outputs standardized enclosure structure status data and anomaly information, accurately reflecting the structural integrity, sealing performance and connection reliability of the enclosure, and providing data support for the enclosure structure dimension for quantifying hazard decision-making. Specifically, the box structure analysis module uses contact displacement sensors at the door panel of the outdoor floor-standing metering box, status sensors at the lock, contact pressure sensors at the sealing strip, and strain sensors at the box frame and connecting bolts to achieve real-time acquisition of five structural parameters: door panel opening and closing displacement S2, lock closing status S3, sealing strip contact pressure P1, box frame strain value ε1, and bolt preload F1. The acquired signals from each sensor are synchronously transmitted to the built-in feature extraction unit, which performs joint feature extraction in the time and frequency domains on the acquired signals, extracting key features such as peak value, mean value, and frequency domain dominant frequency, and eliminating false features caused by random vibrations in the outdoor environment; Furthermore, through the built-in structural analysis unit, the key feature parameters extracted are compared with the preset normal threshold range in real time according to the "Outdoor Power Metering Box Structural Safety Judgment Standard". If a parameter exceeds the threshold, an anomaly is immediately marked and the duration of the anomaly is recorded. At the same time, all feature parameters are converted into standardized box structure status data with uniform dimensions and a value range of [0,1]. Finally, the anomaly information and standardized box structure status data are transmitted to the hidden danger decision-making and classification module in real time.

[0019] The electrical parameter monitoring module collects the core electrical operating parameters inside the outdoor floor-mounted metering box in real time. After completing the identification and classification of electrical parameter anomalies, it outputs standardized electrical operating data and anomaly information, accurately reflecting the electrical safety performance of the metering box and providing electrical dimension data support for quantifying hazard decision-making. Specifically, the electrical parameter monitoring module uses current transformers and voltage transformers at both the inlet and outlet ends of the metering box, and power factor sensors, leakage current sensors, and temperature rise sensors at the internal core components to achieve real-time acquisition of seven electrical parameters: inlet current I1, outlet current I2, inlet voltage U1, outlet voltage U2, power factor cosφ, leakage current I3, and internal component temperature rise T3. The collected raw electrical parameters are compared in real time with the inherent rated operating threshold range of the metering box equipment. According to the degree of exceeding the threshold, electrical anomalies are divided into three levels: mild (less than 10% of the threshold), moderate (10%-30% of the threshold), and severe (more than 30% of the threshold) and marked accordingly. At the same time, all electrical parameters are converted into standardized electrical operating data with uniform dimensions and a value range of [0,1]. Finally, the standardized electrical operating data and anomaly information are transmitted to the hidden danger decision-making and classification module in real time.

[0020] As the core processing node of the entire system, the hazard decision-making and grading module receives standardized data and abnormal information from the three front-end modules of environment, enclosure, and electrical systems. By constructing a quantitative hazard decision-making and evaluation formula, it realizes the quantitative calculation and grading of comprehensive hazards in the metering box, and outputs the comprehensive hazard decision value and corresponding hazard level to the linkage maintenance module and the power emergency monitoring center. This breaks through the traditional technology of judging abnormalities by only using fixed thresholds, effectively reduces the rate of hazard misjudgment and missed judgment, improves the scientificity and accuracy of hazard judgment results, and provides a quantitative decision-making basis for intelligent linkage maintenance and intelligent push of early warning information. Specifically, the hazard decision-making and grading module receives standardized environmental sensing data output by the multi-dimensional environmental sensing module, standardized box structure status data and abnormal information output by the box structure analysis module, and standardized electrical operation data and abnormal information output by the electrical parameter monitoring module in real time. It then performs spatiotemporal alignment and fusion of the real-time data from the three dimensions to obtain fused multi-source effective data. Acquire the following data: internal temperature T1, internal humidity H1, external temperature T2, external humidity H2, atmospheric pressure P, rainfall R, real-time wind speed V, lightning induction intensity L, box vibration amplitude A, and ground settlement S1. Calculate the difference between the internal temperature T1 and the external temperature T2 and take the absolute value |T1-T2|. Also, calculate the difference between the internal humidity H1 and the external humidity H2 and take the absolute value |H1-H2|. The local standard atmospheric pressure value Po is retrieved, and the difference between the atmospheric pressure P and the local standard atmospheric pressure value Po is calculated, with the absolute value |P-Po| being taken. The environmental hazard coefficient E is then calculated using the environmental hazard coefficient quantification formula, as follows: ; Wherein, αn: the hazard weight coefficient of the nth environmental physical quantity, n={1,2,……,9}, corresponding to |T1-T2|, |H1-H2|, R, V, L, C, A, S1, |P-P0| respectively, and the sum of the hazard weight coefficients of all environmental physical quantities is 1. The specific value is determined in advance according to the degree of influence of each environmental physical quantity on the safe operation of the outdoor metering box; Qn: The actual detected value of the nth environmental physical quantity is collected in real time by the corresponding sensor of the environmental multi-dimensional sensing module. The raw value is obtained after signal conditioning and A / D conversion, and then obtained after standardization. Qnw: The danger threshold of the nth environmental physical quantity, which is a fixed value and takes the limit value of each physical quantity specified in the environmental safety standard for outdoor power equipment. It should be noted that Qn / Qnw is the normalized hazard value of the nth environmental physical quantity, with a value of [0,1]. When Qn≥Qnw, this sub-item is 1, which means that the physical quantity has reached a dangerous state. Obtain the door panel opening and closing displacement S2, the lock closing state value S3, the sealing strip contact pressure P1, the box frame strain value ε1, and the bolt preload F1. Subtract the lock closing state value S3 from the value 1, i.e., 1-S3. Also, retrieve the rated contact pressure P1e of the sealing strip and the rated preload F1e of the bolt (both are inherent parameters of the metering box equipment, provided by the equipment manufacturer, and are fixed values). The absolute value of the difference between the rated contact pressure P1e and the contact pressure P1 of the sealing strip is calculated as |P1e-P1|, and the absolute value of the difference between the rated preload F1e and the preload F1 of the bolt is calculated as |F1e-F1|. The structural hazard coefficient X of the enclosure is then calculated using the formula for quantifying the structural hazard coefficient of the enclosure, as follows: ; Wherein, βp: the hidden danger weight coefficient of the p-th structural parameter, p={1,2,……,5}, corresponding to S2, 1-S3, |P1e-P1|, ε1, |F1e-F1| respectively. The sum of the hidden danger weight coefficients of all structural parameters is 1, which is predetermined according to the degree of influence of each structural parameter on the structural safety of the metering box. Jp: The actual detected value of the p-th structural parameter is acquired in real time by the corresponding sensor of the box structure analysis module, and obtained after feature extraction and standardization. Jpw: The danger threshold of the p-th structural parameter, which is a fixed value and is set as the limit value of each parameter specified in the "Outdoor Power Metering Box Structural Design Standard". It should be noted that the sub-item Jp / Jpw is the normalized hazard value of the p-th structural parameter, with a value of [0,1]. When Jp≥Jpw, the sub-item is 1, which means that the structural parameter has reached a dangerous state. Furthermore, the lock closure status value S3 is collected by the status sensor of the box structure analysis module. The value is 1 when the lock is closed and 0 when it is open; 1-S3 is the quantification value of the lock's abnormal status. Obtain the input current value I1, output current value I2, input voltage value U1, output voltage value U2, power factor cosφ, leakage current value I3, and internal component temperature rise value T3. Calculate the difference between the input current value I1 and the output current value I2 and take the absolute value |I1-I2|. The difference between the incoming line voltage U1 and the outgoing line voltage U2 is calculated, and the absolute value |U1-U2| is taken. The power factor cosφ is then subtracted from the value 1, resulting in 1-cosφ. The electrical parameter hazard coefficient D is then calculated using the electrical parameter hazard coefficient quantification formula, as follows: ; Wherein, γm: the hidden danger weight coefficient of the m-th electrical parameter, m={1,2,……,5}, corresponding to |I1-I2|, |U1-U2|, 1-cosφ, I3, T3 respectively. The sum of the hidden danger weight coefficients of all electrical parameters is 1, which is predetermined according to the degree of influence of each electrical parameter on the electrical safety of the metering box. Ym: The actual detected value of the m-th electrical parameter is obtained by real-time acquisition of the corresponding sensor of the electrical parameter monitoring module or by calculation of the acquired data, and is obtained after standardization processing; Ymw: The danger threshold of the m-th electrical parameter, which is a fixed value and is set as the limit value of each parameter specified in the "Electrical Safety Standard for Power Metering Equipment". k: Electrical anomaly grading coefficient, which is marked by the electrical parameter monitoring module according to the degree to which electrical parameters exceed the threshold. No anomaly is 1.0, mild anomaly is 1.2, moderate anomaly is 1.5, and severe anomaly is 2.0, realizing the quantitative correction of the degree of electrical anomaly. It should be noted that the sub-item Ym / Ymw is the normalized hazard value of the m-th electrical parameter, with a value of [0,1]. When Ym≥Ymw, the sub-item is 1, which means that the electrical parameter has reached a dangerous state. After calculating the environmental hazard coefficient E, the enclosure structure hazard coefficient X, and the electrical parameter hazard coefficient D, a quantitative formula for the comprehensive hazard decision value of the metering box is constructed. The specific formula is as follows: ; Where w1: environmental hazard weighting coefficient; W2: enclosure structure hazard weighting coefficient; W3: electrical parameter hazard weighting coefficient; and w1+W2+W3=1; After calculating the comprehensive hazard decision value S using the formula, the hazard decision for the metering box is divided into four levels based on the comprehensive hazard decision value S: If S∈[0,0.2), the outdoor floor-standing meter box is judged as a low-risk hazard; if S∈[0.2,0.5), the outdoor floor-standing meter box is judged as a medium-risk hazard; if S∈[0.5,0.8), the outdoor floor-standing meter box is judged as a high-risk hazard; if S≥0.8, the outdoor floor-standing meter box is judged as an extremely high-risk hazard.

[0021] The linkage and control module, based on the preset hierarchical linkage and control strategy, issues precise control instructions to each actuator of the outdoor ground-mounted metering box to perform safety control and protection of the outdoor ground-mounted metering box, and sends the control and protection execution information to the power emergency monitoring center. It formulates targeted hierarchical linkage and control strategies based on the quantitative hazard level, realizes gradient control from routine monitoring to emergency power outage, and issues targeted and precise instructions such as heat dissipation, interlocking, and power outage, thereby improving the pertinence and effectiveness of safety protection and helping to minimize equipment failure losses.

[0022] Furthermore, the power emergency monitoring center receives real-time data on potential hazards, control information, and alarm signals transmitted from each module, enabling centralized monitoring of the safety status of outdoor ground-mounted metering boxes and coordinated emergency response, thus ensuring timely and comprehensive supervision.

[0023] It should be noted that the linkage and maintenance module receives the S, hazard level, and hazard coefficients (E, X, D) from the hazard decision-making and grading module in real time. Based on the hazard level, it matches a preset tiered linkage and maintenance strategy. This strategy library is built according to the "Safety Protection Specification for Outdoor Power Metering Boxes" and covers targeted maintenance actions across three dimensions: environment, box structure, and electrical systems. Specific control and protection strategies can be found below: For low-risk levels (S∈[0,0.2)): only send routine collection frequency commands to the environmental multi-dimensional sensing module, without any other adjustment actions, and keep the metering box in normal operation; For medium-level hidden danger (S∈[0.2,0.5)): perform primary maintenance actions, control the start of the built-in cooling fan and dehumidifier of the metering box, adjust the temperature and humidity inside the box to a safe range, control the deployment of the protective baffle outside the box to resist slight wind, rain and sand intrusion, and at the same time send a re-inspection instruction to the box structure analysis module to perform high-frequency re-inspection of the structural parameters marked as abnormal. For high-risk levels (S∈[0.5,0.8)): On the basis of the primary maintenance action, the intermediate maintenance action is performed, the corrosive gas adsorption device in the metering box is started to reduce the concentration of corrosive gas in the box, the overcurrent and leakage protection devices are adjusted to the warning state, the non-core electrical circuits of the metering box are shut down to reduce the electrical load, and at the same time, high-frequency monitoring instructions are sent to the electrical parameter monitoring module. For extremely high hazard levels (S≥0.8): On the basis of intermediate maintenance actions, perform advanced maintenance actions, immediately trigger the emergency electrical protection device of the metering box, cut off the main electrical circuit to prevent the electrical accident from escalating, control the emergency interlocking device of the box to lock the door to prevent human error, control the lightning protection device on the top of the box to activate to resist lightning damage, and at the same time issue on-site emergency maintenance instructions to the surrounding power inspection terminals.

[0024] Example 2: Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the linkage adjustment module is communicatively connected to the protection hazard early warning module. The linkage adjustment module sends the control and protection execution information to the protection hazard early warning module. The protection hazard early warning module is used to set the detection period and analyze the degree of protection hazard for the outdoor floor-mounted metering box during the detection period. Through analysis, it determines whether to generate a protection hazard alarm signal, and when a protection hazard alarm signal is generated, it is sent to the power emergency monitoring center to remind management personnel to take corresponding improvement measures, ensure the efficient and stable operation of all actuators, and further strengthen the safety protection line of the outdoor floor-mounted metering box. The specific analysis process is as follows: All actuators involved in the safety control and protection of outdoor ground-mounted metering boxes are obtained. The execution risk value is calculated by the ratio of the number of execution failures of the corresponding actuators (i.e. the number of times they failed to execute the received control commands normally) to the total number of executions during the detection period. The average value of the action delay time of the corresponding actuators (i.e. the time interval from receiving the control command to making a response) during the detection period is marked as the execution delay value. The execution risk coefficient is calculated by weighted summation of the execution risk value and the execution delay value. Specifically, each execution risk value and execution delay value is assigned a corresponding preset weight coefficient, and each is multiplied by its respective preset weight coefficient. The sum of the two products is then marked as the execution risk coefficient. It should be noted that the larger the execution risk coefficient, the worse the overall performance of the corresponding execution agency during the detection period, and the higher the execution risk. Furthermore, the execution hazard coefficient of the corresponding actuator is compared with the corresponding preset execution hazard coefficient threshold, and the actuator whose execution hazard coefficient exceeds the corresponding preset execution hazard coefficient threshold is marked as a hazard actuator; if a hazard actuator exists, it indicates that the safety control and protection of the outdoor ground meter box has a high risk, and the corresponding actuator needs to be repaired, replaced or strengthened for supervision, and a protection hazard alarm signal is generated.

[0025] The working principle of this invention is as follows: During use, it comprehensively collects data on the internal and external environment, box structure, and core electrical parameters. After standardized processing and anomaly marking, it provides comprehensive and reliable data support for hazard assessment. By integrating multi-source data, it accurately calculates the comprehensive hazard decision value and classifies it into four levels, breaking through the limitations of fixed threshold judgment and reducing the false omission rate. The linkage maintenance module executes a gradient maintenance strategy according to the hazard level, accurately adapting from routine monitoring to emergency power outage, improving the targeting and effectiveness of protection. The hazard warning module monitors the operating status of the actuator, marks the hazard mechanism and alarms, and builds a solid secondary protection line. Overall, it realizes comprehensive, precise, and intelligent safety supervision of outdoor floor-mounted metering boxes, greatly improving the operational safety and stability of metering boxes in complex outdoor environments, minimizing equipment failure and safety accident losses, and adapting to the long-term supervision needs of outdoor floor-mounted metering boxes.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
