Description

Technical Field

[0001] The present invention relates to the field of data processing technology or other related fields, and in particular to an operation alarm method and device, and electronic equipment for a confined space of a power grid. Background Art

[0002] Confined space operations are also known as restricted space operations or confined space operations. Confined space refers to a space that is relatively isolated from the outside world, has limited entrances and exits, and has poor natural ventilation. It is large enough to accommodate one person to enter and engage in unconventional and non-continuous operations. Confined spaces include furnaces, towers, kettles, tanks, tank trucks, pipelines, flues, sewers, tunnels, ditches, pits, wells, pools, culverts, cabins, underground warehouses, storage rooms, cellars, and barns, etc., while confined spaces in power grids include but are not limited to cable wells, deep foundation pits, the inside of transformers, and accident oil pools.

[0003] Related technologies have proposed risk assessment strategies for confined spaces in power grids. These strategies obtain basic information about the work object and use it to determine its safety level. Furthermore, the safety level of the confined space is determined by the safety factor, resulting in a risk level that is then used for risk assessment. However, existing strategies suffer from the technical challenge of difficult real-time monitoring of environmental data and the vital signs of the work object. This results in an inability to issue timely alarms in the event of environmental hazards or abnormal vital signs of the work object. This not only reduces work efficiency but can also lead to safety incidents, failing to ensure the safety of the work object.

[0004] To address the above-mentioned problems, no effective solutions have been proposed so far. Summary of the Invention

[0050] The present invention will be described in detail below with reference to various embodiments.

[0051] Example 1

[0052] According to an embodiment of the present invention, an embodiment of an operation alarm method for a confined space in a power grid is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0053] Figure 1 FIG. 1 is a flow chart of an optional method for alarming an operation in a limited space of a power grid according to an embodiment of the present invention. Figure 1 As shown, the method includes the following steps:

[0054] Step S101: Acquire the working environment data of the limited space, calculate the natural environment assessment value based on the natural environment data in the working environment data, and send an alarm prompt to suspend the work when the natural environment assessment value is less than the natural environment assessment threshold.

[0055] In an embodiment of the present invention, by obtaining the operating environment data of the confined space, including the natural environment data and the power grid environment data inside the confined space, the natural environment assessment value is calculated based on the natural environment data in the operating environment data. When the natural environment assessment value is less than the natural environment assessment threshold, it is considered that there is an operating risk in the natural environment where the confined space is located. At this time, an alarm prompt to suspend the operation will be sent to warn the operating object that it cannot operate; when the natural environment assessment value is greater than or equal to the natural environment assessment threshold, it is considered that the natural environment where the confined space is located can be operated, and the power grid environment inside the confined space is further judged whether there is an operating risk.

[0056] It should be noted that the embodiments of the present invention pre-design a structured database to store the data of the embodiments of the present invention. The natural environment assessment thresholds are obtained from the database and are determined based on industry safety standards, regulatory requirements, historical data, and experience. They are set by analyzing potential risks and accident cases in specific operating environments, considering the safety tolerances of equipment and operating objects, and combining literature, manufacturer recommendations, and experimental data to ensure that the natural environment assessment thresholds can effectively prevent accidents and health problems caused by natural environmental factors. The natural environment assessment thresholds are regularly updated to adapt to new developments and safety standards.

[0057] Optionally, the step of calculating the natural environment assessment value includes: obtaining the natural environment definition data corresponding to the confined space, wherein the natural environment definition data includes: the defined temperature, defined humidity, and defined harmful gas content of the confined space; obtaining the body width of the work object, and fusing the body width, natural environment data, and natural environment definition data to obtain the natural environment assessment value, wherein the natural environment data includes: the measured temperature, measured humidity, measured harmful gas content, and measured passable width in the confined space.

[0058] In the embodiment of the present invention, the calculation of the natural environment assessment value requires obtaining the natural environment data, the width of the work object, and the natural environment definition data corresponding to the limited space, and the natural environment assessment value is obtained by fusing the three.

[0059] Among them, natural environment data includes the measured temperature, measured humidity, measured harmful gas content and measured passable width in a confined space. Natural environment data can be obtained through sensors and monitoring equipment. Temperature and humidity sensors can monitor and record the temperature and humidity levels in a confined space in real time. Harmful gas sensors are used to monitor the concentration of specific harmful gases in a confined space, such as carbon monoxide, hydrogen sulfide, methane, etc. The data collected by the sensors is usually real-time, which means that the natural environment data will be continuously sent to the central monitoring system or control room. Natural environment data is usually transmitted via wired (such as Ethernet) or wireless (such as Bluetooth). Wired connections are preferred in confined spaces such as cable wells, deep foundation pits, inside transformers, and accident oil pools.

[0060] The natural environment definition data corresponding to the confined space is obtained from the database. The natural environment definition data is determined with reference to relevant industry standards, safety specifications and internal company operating procedures. These standards provide the basis for safety limits, such as the maximum allowable temperature, humidity, and harmful gas concentration.

[0061] Temperature and humidity have a direct impact on human thermal comfort and physiological function. Extreme temperatures and humidity not only cause discomfort but can also trigger heat shock and other problems, such as heatstroke in high-temperature environments or increased fatigue in high-humidity environments. Confined spaces within power grids often accumulate harmful gases due to poor ventilation, posing a direct threat to the health of workers. Toxic gases such as carbon monoxide and hydrogen sulfide can be fatal even at low concentrations. The accessible width is a key physical parameter for determining whether the confined space within a power grid is sufficient to accommodate workers for safe operation. The worker's body width must also be considered to ensure they do not become trapped or have difficulty navigating within the confined space. This is crucial for the feasibility of emergency evacuations and overall operational safety. The measured temperature, humidity, and harmful gas content jointly determine the comfort and safety of the natural environment, while the measured accessible width and the worker's body width directly impact the feasibility of operations and the ability to escape in an emergency.

[0062] The embodiment of the present invention integrates natural environment data, the body width of the work object and the natural environment definition data corresponding to the confined space, and calculates the natural environment assessment value to comprehensively evaluate whether the natural environment meets the work requirements. When the natural environment assessment value exceeds the natural environment assessment threshold, an alarm is issued to suspend the work. When the natural environment assessment value does not exceed the natural environment assessment threshold, the work object is allowed to work.

[0063] Optionally, the step of fusing the body width, the natural environment data, and the natural environment definition data to obtain the natural environment assessment value includes: inputting the body width, the natural environment definition data, and the natural environment data into a first formula to calculate the natural environment assessment value, where the first formula is:

[0064]

[0065] Among them, Zp is the natural environment assessment value, wS is the measured temperature, sS is the measured humidity, qS is the measured harmful gas content, Kxk is the measured passable width, wD is the defined temperature, sD is the defined humidity, qD is the defined harmful gas content, and Tk is the body width.

[0066] In an embodiment of the present invention, the natural environment assessment value is calculated by the first formula. The calculation formula of the natural environment assessment value is designed to be a complex function that comprehensively considers multiple environmental factors and actual working space requirements. The purpose is to provide a quantitative and comprehensive evaluation index for judging the safety of the natural environment in which the confined space is located.

[0067] Temperature, humidity, and hazardous gas content are fundamental elements in assessing work environment safety and are directly related to the health and safety of workers. The differences between these parameters and their respective safety thresholds are used to assess the suitability of the natural environment. Considering that physical accessibility in confined spaces is a key requirement for safe operations, the relationship between the measured accessible width and the width of the worker is assessed to ensure that the worker can safely enter the confined space. By using an exponential function, the sensitivity of the measured natural environment values ​​to deviations from the thresholds can be weighted, making the natural environment assessment more sensitive to changes in the measured natural environment values. This is particularly effective in identifying changes when these measured natural environment values ​​approach or exceed their safety thresholds.

[0068] Through the first formula, various factors of the natural environment are comprehensively considered, and a unified assessment value is used to quickly determine whether the minimum safety requirements of the operation are met. This helps operation managers quickly make decisions on whether to suspend the operation, effectively prevent the occurrence of safety accidents, and ensure the safety of the operation object.

[0069] Step S102, when the natural environment assessment value is greater than or equal to the natural environment assessment threshold, the power grid environment assessment value is calculated based on the confined space internal power grid environment data in the operating environment data. When the power grid environment assessment value is greater than the power grid environment assessment threshold, an alarm prompt is sent to suspend the operation, wherein the confined space internal power grid environment data includes: power grid voltage, power grid equipment temperature, and sound value.

[0070] In an embodiment of the present invention, if the natural environment assessment value is greater than or equal to the natural environment assessment threshold, meaning that the operator is permitted to operate in the natural environment of the confined space, a power grid environment assessment value is calculated based on the confined space internal power grid environment data in the operating environment data. Based on this power grid environment assessment value, it is determined whether the confined space internal environment presents an operational risk. If the power grid environment assessment value is greater than the power grid environment assessment threshold, the confined space internal environment is deemed to present an operational risk, and an alarm prompting the operator to suspend operations is issued, warning the operator that the operation cannot proceed. If the power grid environment assessment value is less than or equal to the power grid environment assessment threshold, the confined space internal environment is deemed to permit operations, and the operator's identity information and equipment information are further verified.

[0071] Environmental data for power grids within confined spaces includes grid voltage, grid equipment temperature, and sound levels. This data can be obtained using dedicated monitoring equipment. Voltage sensors are used to measure and monitor grid voltage levels. Clamp-on ammeters are clamped directly onto cables, or other types of voltage detection equipment are installed at various points in the circuit to monitor grid voltage. The temperature of grid equipment such as transformers and cables can be monitored using thermocouples or infrared thermometers. Sound levels are typically obtained using sound sensors, such as sound level meters.

[0072] Grid voltage is a fundamental and critical data point in the power system. Its stability directly impacts the operation of the entire grid. Abnormal grid voltage can cause equipment damage, operational failure, and even safety incidents. Monitoring grid equipment temperature helps prevent equipment failure and shortened lifespan due to overheating. Abnormal temperatures are a direct indicator of potential equipment failures and overloads. Acoustic level monitoring detects abnormal sounds during grid equipment operation. These sounds often serve as early warnings of equipment failures, electrical faults, or other problems. Although grid voltage, grid equipment temperature, and acoustic levels independently measure different physical quantities, they actually influence each other within the power grid system. For example, unstable grid voltage can cause equipment overheating, which in turn can cause material expansion and produce abnormal noise. Furthermore, abnormal noise emitted by equipment may be due to increased friction caused by abnormal grid voltage or current.

[0073] The grid environment assessment thresholds are obtained from the database. They are determined based on industry safety standards, regulatory requirements, historical data, and experience. They are set by analyzing potential risks and accident cases in specific operating environments, taking into account the safety tolerances of equipment and operating objects, and combining literature, manufacturer recommended standards, and experimental data to ensure that the grid environment assessment thresholds can effectively prevent accidents and health problems caused by grid environmental factors. The grid environment assessment thresholds are updated regularly to adapt to new developments and safety standards.

[0074] Optionally, the step of calculating the power grid environment assessment value includes: obtaining the confined space internal power grid environment definition data corresponding to the confined space, wherein the confined space internal power grid environment definition data includes: power grid definition voltage, power grid equipment definition temperature, and definition sound value; fusing the confined space internal power grid environment data with the confined space internal power grid environment definition data to obtain the power grid environment assessment value.

[0075] In the embodiment of the present invention, calculation of the power grid environment assessment value requires obtaining the confined space internal power grid environment definition data and the confined space internal power grid environment data corresponding to the confined space, and obtaining the power grid environment assessment value by fusing the two.

[0076] Among them, the internal power grid environment definition data of the confined space corresponding to the confined space is obtained from the database. The internal power grid environment definition data of the confined space is determined with reference to relevant industry standards, relevant safety specifications and standards, and the company's internal operating procedures. At the same time, for the defined temperature and defined sound value of the power grid equipment, it is also necessary to refer to the operating specifications and safety operating guidelines provided by the equipment manufacturer.

[0077] Optionally, the step of fusing the confined space internal power grid environment data with the confined space internal power grid environment definition data to obtain the power grid environment assessment value includes: inputting the confined space internal power grid environment data and the confined space internal power grid environment definition data into a second formula to calculate the power grid environment assessment value, where the second formula is:

[0078]

[0079] Where Dp is the grid environment assessment value, dY is the grid voltage, dW is the grid equipment temperature, dS is the sound value, dcY is the grid boundary voltage, dcW is the grid equipment boundary temperature, dcS is the boundary sound value, and e is a natural constant.

[0080] In an embodiment of the present invention, the confined space internal power grid environment data and the confined space internal power grid environment definition data are integrated according to the second formula, and the calculation formula of the power grid environment assessment value is used to measure the degree of deviation between the actual internal power grid environment data and its safety definition value, providing an intuitive strategy to evaluate the overall deviation of all key data. By using the exponential function form of a natural constant, the sensitivity of the power grid environment assessment value to deviation is enhanced. When the actual internal power grid environment data deviates from the safety range of the definition value, even a small change will cause the power grid environment assessment value to increase significantly, which can make the decision more sensitive and timely, thereby enhancing the effect of safety warning. By comparing the calculated power grid environment assessment value with the power grid environment assessment threshold stored in the database, it is possible to dynamically determine whether the current confined space internal power grid environment is suitable for operation.

[0081] The second formula takes into account three key data points: grid voltage, equipment temperature, and sound level, ensuring a comprehensive assessment of the grid environment within a confined space. This comprehensive assessment strategy helps monitor the grid's operating status from multiple aspects and prevent other potential risks from being missed due to anomalies in a single data point.

[0082] Step S103, when the grid environment assessment value is less than or equal to the grid environment assessment threshold, obtain the identity information of the operation object; when the identity information does not match the specified identity information, determine that the operation object is non-compliant and send an alarm prompt to suspend the operation.

[0083] In an embodiment of the present invention, when the power grid environment assessment value is less than or equal to the power grid environment assessment threshold, that is, when the natural environment and the internal power grid environment of the confined space are both safe, the identity information of the operation object is obtained to determine whether the identity information of the operation object is compliant. When the identity information of the operation object does not match the specified identity information, the operation object is considered to be non-compliant, an alarm prompt to suspend the operation is sent, and the operation object is not allowed to enter the confined space for operation; when the identity information of the operation object completely matches the specified identity information, the operation object is considered to be compliant, and it is allowed to enter the confined space.

[0084] The identity information of the work object includes employee number, name, etc. By comparing the identity information of the work object with the identity information of the designated work object in the limited space stored in the database, only when the identity information of the work object completely matches the designated identity information in the database will it be considered a compliant work object. This step ensures that only authorized work objects can enter the limited space to perform work.

[0085] Step S104, when the identity information matches the specified identity information, the device information carried by the operation object is obtained; when the device information does not match the specified device information, the operation object is determined to be non-compliant and an alarm prompt for suspending the operation is sent.

[0086] In this embodiment of the present invention, after identity verification is passed, the operator further checks whether the equipment information carried by the operator matches the equipment information required for the confined space in the database. This equipment information includes safety equipment and tool information. If the equipment information carried by the operator does not match the specified equipment information in the database, the operator is considered non-compliant, an alarm prompting the operator to suspend operations is issued, and the operator is not allowed to enter the confined space to work. Only when the equipment information carried completely matches the specified equipment information in the database is the operator allowed to enter the confined space to work. This step ensures that all operators carry the appropriate equipment to complete the work task, reducing safety risks.

[0087] Step S105, when the device information matches the designated device information, the vital sign monitoring evaluation value is calculated based on the vital sign data of the operation object. When the vital sign monitoring evaluation value is greater than the vital sign monitoring evaluation threshold, it is determined that the vital sign of the operation object is abnormal, and an alarm prompt for suspending the operation is sent.

[0088] In an embodiment of the present invention, when the identity information of the operating subject and the information of the equipment carried by the operating subject match the corresponding information in the database, the operating subject enters the confined space to perform the operation. After the operating subject enters the confined space, the operating subject's vital sign data is monitored in real time, and a vital sign monitoring evaluation value is calculated based on the vital sign data. The vital sign monitoring evaluation value is used to determine whether the operating subject's vital signs are normal. If the vital sign monitoring evaluation value is greater than the vital sign monitoring evaluation threshold, the operating subject's vital signs are considered abnormal, and an alarm prompt is sent to warn the operating subject to suspend the operation. If the vital sign monitoring evaluation value is less than or equal to the vital sign monitoring evaluation threshold, the operating subject's vital signs are considered normal and the operating subject can continue the operation.

[0089] Vital sign monitoring and assessment thresholds are obtained from a database and are typically derived based on historical data, safety standards, and specific operational experience. First, by collecting and analyzing historical vital sign data from workers, we study how this data changes under different working conditions and the thresholds that impact health. Then, combining industry safety standards and medical recommendations, we establish thresholds appropriate for specific work environments. These thresholds effectively indicate worker health risks, thus ensuring operational safety.

[0090] Based on natural environmental data, reasonable allowable deviation data for vital sign status is determined, including the allowable fluctuation range of body temperature, heart rate, and respiratory rate. The vital sign status definition data of the working object is obtained from the database. The measured vital sign data is integrated with the vital sign status definition data to generate a vital sign monitoring assessment value. The vital sign monitoring assessment value takes into account the difference between the actual measurement and the predetermined standard to determine whether the current physiological state of the working object is within a safe range. Based on the vital sign monitoring assessment value, it is determined whether the working object can continue to work. If the vital sign monitoring assessment value exceeds the vital sign monitoring assessment threshold, it is recommended to stop the work and take corresponding measures; if it does not exceed the vital sign monitoring assessment threshold, the work can continue. Real-time monitoring of vital sign data can quickly identify working objects at health risks, issue alarm prompts in time, and take measures such as evacuation or providing medical assistance, thereby reducing the risk of serious health problems and accidents.

[0091] Optionally, the step of calculating the vital sign monitoring evaluation value includes: determining the allowable deviation data of the vital sign status of the working object based on the natural environment data, wherein the allowable deviation data of the vital sign status include: the allowable deviation value of body temperature, the allowable deviation value of heart rate, and the allowable deviation value of respiratory rate; obtaining the vital sign status definition data corresponding to the working object, wherein the vital sign status definition data include: the body temperature definition value, the heart rate definition value, the respiratory rate definition value, and the water evaporation definition value; fusing the vital sign data with the vital sign status definition data to obtain the vital sign monitoring evaluation value, wherein the vital sign data include: the actual measured value of body temperature, the actual measured value of heart rate, the actual measured value of respiratory rate, and the actual measured value of water evaporation.

[0092] In an embodiment of the present invention, the calculation of the vital sign monitoring evaluation value first determines the allowable deviation data of the vital sign status of the working object based on the natural environment data, and then combines the allowable deviation data of the vital sign status to fuse the vital sign data and the vital sign status definition data to obtain the vital sign monitoring evaluation value.

[0093] Vital status definition data is obtained from a database and establishes safety thresholds for the worker's body temperature, heart rate, respiratory rate, and water evaporation. This data is typically obtained by monitoring the worker's body temperature, heart rate, respiratory rate, and water evaporation in a controlled environment, simulating confined space conditions, to determine physiological parameters for safe operation. Given that each worker's physiological responses may vary, personalized vital status definition data can more precisely protect the health of each worker.

[0094] Vital sign data include actual body temperature, heart rate, respiratory rate, and water evaporation. The actual body temperature is measured using an electronic thermometer, the heart rate is obtained using a chest strap or wristband heart rate monitor, the respiratory rate is measured by sensing the expansion and contraction of the chest cavity using a respiratory rate monitoring device, and the water evaporation is obtained by monitoring the water evaporation rate on the skin surface using a water evaporation sensor. By collecting the temperature, heart rate, respiratory rate, and water evaporation data of the operating subject in real time, the physiological state of the operating subject in a specific working environment can be known. If the vital sign monitoring assessment value exceeds the vital sign monitoring assessment threshold, it indicates that the operating subject may be at risk of health abnormalities or excessive physiological stress, and the work should be stopped immediately. If the vital sign monitoring assessment value does not exceed the vital sign monitoring assessment threshold, it indicates that the physiological state of the operating subject is stable and the work can continue safely.

[0095] Body temperature is a fundamental vital sign, reflecting the body's thermal balance. Monitoring body temperature is particularly important when working in extreme environments (such as high or low temperatures) as it can indicate whether the body is properly regulating its temperature. Heart rate reflects the load on the heart and the body's response to the workload. During physical labor or stressful conditions, changes in heart rate can indicate the stress on the cardiovascular system and the body's stress response. Respiratory rate is an important indicator of respiratory system function and metabolic levels. Monitoring respiratory rate is particularly important in environments containing harmful gases or low oxygen. Water evaporation rate reflects the body's water loss and heat dissipation capacity. In high-temperature environments or when wearing protective clothing, monitoring water evaporation can help prevent dehydration and heat exhaustion. Furthermore, body temperature, heart rate, respiratory rate, and water evaporation data are interrelated. Thermoregulation is closely linked to water evaporation. When the ambient temperature rises or the intensity of physical labor increases, the body dissipates heat through increased sweat evaporation to maintain a stable body temperature. When body temperature rises, heart rate typically also increases because the body requires more blood flow to help dissipate heat. During periods of high exertion or environmental stress, heart rate and respiratory rate often increase in tandem as the body attempts to cope with increased metabolic demands by increasing oxygen intake and carbon dioxide output. In hot or dry environments, as the rate of evaporation increases, an increase in respiratory rate may be necessary to regulate body water and temperature.

[0096] Optionally, the step of fusing the vital sign data with the vital sign status definition data to obtain the vital sign monitoring evaluation value includes: inputting the vital sign status allowable deviation data, the vital sign status definition data, and the vital sign data into a third formula to calculate the vital sign monitoring evaluation value, and the third formula is:

[0097]

[0098] Among them, TzP is the vital sign monitoring assessment value, sTw is the actual measured value of body temperature, sXw is the actual measured value of heart rate, sHw is the actual measured value of respiratory rate, SfZ is the actual measured value of water evaporation, cTw is the body temperature limit value, cXw is the heart rate limit value, cHw is the respiratory rate limit value, cfZ is the water evaporation limit value, ΔTw is the allowable deviation value of body temperature, ΔXw is the allowable deviation value of heart rate, ΔHw is the allowable deviation value of respiratory rate, and e is a natural constant.

[0099] In an embodiment of the present invention, the vital sign data and the vital sign status definition data are fused according to the third formula to obtain a vital sign monitoring evaluation value. The calculation formula of the vital sign monitoring evaluation value is to standardize the difference between the actual vital sign value and the vital sign status definition value according to the allowable deviation range, so that the degree of deviation of different data can be compared and accumulated on the same scale, providing a unified metric. The third formula uses a logarithmic function for weighting and conversion, which can reduce the impact of outliers and prevent extreme data from causing excessive deviations in the evaluation results. Logarithmic transformation can make the changes in the evaluation value smoother and avoid sharp changes in the evaluation value due to extreme deviations of individual data. This section is designed to place particular emphasis on the impact of evaporation values. Changes in evaporation rate are crucial for thermoregulation and body water balance, particularly in hot environments or during high-intensity work. The use of an exponential function to enhance its influence ensures that even small changes are appropriately reflected in the overall assessment, which can play a significant role in assessing the risks associated with heat stress.

[0100] The calculation formula for the vital sign monitoring assessment value combines four key physiological indicators: body temperature, heart rate, respiratory rate and water evaporation, providing a comprehensive method for evaluating the current physiological state of the working object. By integrating these key indicators, a more comprehensive assessment can be made as to whether the working object is in a healthy and safe working state.

[0101] Optionally, the step of determining the allowable deviation data of the physical sign state of the work object based on the natural environment data includes: obtaining a mapping table of the allowable deviation data of the physical sign state and natural environment matching data, wherein the natural environment matching data includes: matching temperature, matching humidity, matching harmful gas content, and matching passable width; inputting each natural environment matching data in the mapping table and the natural environment data into a fourth formula respectively to calculate a plurality of comparison coefficients, and the fourth formula is:

[0102]

[0103] Among them, BDx is the comparison coefficient, wS is the measured temperature, sS is the measured humidity, qS is the measured harmful gas content, Kxk is the measured passable width, Tw is the matching temperature, Xw is the matching humidity, Hw is the matching harmful gas content, and Kw is the matching passable width; the allowable deviation data of the physical sign state corresponding to the comparison coefficient with the smallest value is used as the allowable deviation data of the physical sign state of the operation object.

[0104] In an embodiment of the present invention, to determine the allowable deviation data of the physical sign status of the working object, it is first necessary to obtain a mapping table of the allowable deviation data of the physical sign status and the natural environment matching data, and then input each natural environment matching data and the natural environment data in the mapping table into the fourth formula respectively, and calculate multiple comparison coefficients. The allowable deviation data of the physical sign status corresponding to the comparison coefficient with the smallest value is used as the allowable deviation data of the physical sign status of the working object.

[0105] The mapping table contains the association between the natural environment matching data and the allowable deviation data of the physical sign status. These matching data include matching temperature, matching humidity, matching harmful gas content and matching passable width, which are all key environmental factors that affect the health of the working object. The comparison coefficient is obtained by comparing the measured natural environment data with the natural environment matching data in the mapping table. This process aims to find the standard configuration that is closest to the current natural environment conditions to ensure the accuracy and applicability of the assessment. Selecting the minimum value according to the comparison coefficient, that is, selecting the deviation data closest to the actual natural environment conditions, ensures that the allowable deviation of the assessed physical sign status best reflects the actual risks and needs in the current natural environment. The safety standards are adjusted according to the specific conditions of each working environment, making safety management more precise and personalized, and improving the effectiveness of protective measures.

[0106] Mapping tables between permissible deviations for vital signs and matching data for natural environments are obtained from a database. These mapping tables are developed through professional safety assessments, experimental research, and historical data analysis. First, a team of safety and medical experts determines the permissible deviation ranges for vital signs under various environmental conditions based on experimental observations and historical operational data from different natural environments. This data is then standardized through statistical analysis and matched to the corresponding natural environmental conditions to form mapping tables. Finally, these mapping tables are entered into a specially designed database for real-time matching and evaluation before the work subjects actually begin work, ensuring they can safely adapt to their specific working environments.

[0107] In the fourth formula, the calculation of the comparison coefficient, the square root is used to mitigate the impact of extreme deviations. The square root can make the impact of deviations more moderate and prevent extreme outliers of a single variable from having an excessive impact on the overall comparison coefficient. By dividing by the natural environment matching data, that is, the ideal or target value of each natural environment data, the differences are normalized. This ensures that the deviations of different natural environment parameters at their own magnitude contribute to the comparison coefficient, so that the results are not biased by differences in parameter units or magnitudes. By summing up all normalized square root deviations, the impact of each natural environment data on the suitability of the current working conditions can be synthesized. This synthesis is used to assess the overall consistency of the actual natural environment conditions with the preset standards.

[0108] The steps provided by the above-mentioned power grid confined space operation alarm method can be achieved by obtaining the operation environment data of the confined space, calculating the natural environment assessment value based on the natural environment data in the operation environment data, and judging whether the natural environment in which the confined space is located has operation risks according to the natural environment assessment value. After determining that the natural environment is safe, the power grid environment assessment value is calculated based on the internal power grid environment data of the confined space in the operation environment data, and judging whether the internal power grid environment of the confined space has operation risks according to the power grid environment assessment value. After determining that the internal power grid environment is safe, the identity information of the operation object is further obtained. If the identity information does not match the specified identity information, the equipment information carried by the operation object is obtained to judge whether the equipment information matches the specified equipment information, ensuring that only authorized operation objects and equipment can enter the confined space. For the operation object that has entered the confined space to perform operation tasks, the vital sign data is continuously monitored, and the vital sign monitoring assessment value is calculated based on the vital sign data of the operation object, and whether the operation object is suitable for continuing the operation is judged according to the vital sign monitoring assessment value.

[0109] The embodiment of the present invention ensures that the operating object is allowed to operate only when all safety conditions are met through precise data analysis, significantly reducing the risks and potential accidents in the work. All decisions are based on real-time data and preset safety standards, reducing the interference of human errors and subjective judgments. The real-time updated operating environment data and the characteristic data of the operating object improve the response capability to emergencies, ensuring that the operation can continue under the premise of safety, and reducing unnecessary work interruptions caused by safety issues. During the operation process, by continuously monitoring the operating environment data and the characteristic data of the operating object, once abnormal environmental data and abnormal characteristic data are detected, an alarm prompt will be immediately issued to warn the operating object to suspend the operation and take corresponding measures to prevent the occurrence of safety accidents. This solves the technical problem in the related art that the environmental data and the vital signs data of the operating object cannot be monitored in real time, resulting in untimely alarms.

[0110] The following describes it in detail with reference to another embodiment.
