[0051] Embodiment One

[0052] According to the embodiments of the present application, an embodiment of a power grid limited space operation alarm method 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, the steps shown or described herein can be executed in a different order in some cases.

[0053] Figure 1 is a flowchart of an optional power grid limited space operation alarm method according to the embodiments of the present application, as shown in Figure 1 The method comprises the following steps:

[0054] In step S101, operation environment data of a limited space is obtained, a natural environment evaluation value is calculated based on natural environment data in the operation environment data, and an alarm prompt to suspend operation is sent in the case that the natural environment evaluation value is less than a natural environment evaluation threshold value.

[0055] In the embodiment of the present application, by acquiring the work environment data of the limited space, including the natural environment data and the internal power grid environment data of the limited space, the natural environment evaluation value is calculated based on the natural environment data in the work environment data, when the natural environment evaluation value is less than the natural environment evaluation threshold value, it is considered that the natural environment where the limited space is located has work risk, at this time, the alarm prompt of suspending work is sent to warn the work object that it cannot work, when the natural environment evaluation value is greater than or equal to the natural environment evaluation threshold value, it is considered that the natural environment where the limited space is located can work, and further, whether the internal power grid environment of the limited space exists work risk is judged.

[0056] It should be noted that the embodiment of the present application is designed with a structured database in advance to store the data of the embodiment of the present application. The natural environment evaluation threshold value is obtained from the database, and the natural environment evaluation threshold value is determined according to the industry safety standards, regulations and historical data and experience, by analyzing the potential risks and accident cases in the specific work environment, considering the safety margin of the equipment and the work object, combining with the literature materials, manufacturer's recommended standards and experimental data to determine, so as to ensure that the natural environment evaluation threshold value can effectively prevent accidents and health problems caused by natural environment factors, and the natural environment evaluation threshold value is updated regularly to adapt to new development and safety standards.

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

[0058] In the embodiment of the present application, the calculation of the natural environment evaluation value needs to acquire the natural environment data, the body width of the work object and the natural environment definition data corresponding to the limited space, and the natural environment evaluation value is obtained by fusing the three.

[0059] The natural environment data includes measured temperature, measured humidity, measured harmful gas content and measured passable width in the limited space, and the natural environment data can be obtained through sensors and monitoring equipment. The temperature and humidity sensor can monitor and record the temperature and humidity level in the limited space in real time, and the harmful gas sensor is used to monitor the concentration of specific harmful gases in the limited space, such as carbon monoxide, hydrogen sulfide, methane, etc. The data collected by the sensor is usually real-time, which means that the natural environment data is continuously sent to the central monitoring system or control room. The natural environment data is usually transmitted through wired (such as Ethernet) or wireless (such as Bluetooth) methods, and wired connection is preferred in cable shafts, deep foundation pits, transformer interiors and limited spaces of accident oil pools.

[0060] The natural environment definition data corresponding to the limited space is obtained from a database, and the natural environment definition data is determined with reference to relevant industry standards, safety specification standards and company internal operation procedures, which provide the basis for safety limits such as the maximum allowed temperature, humidity, harmful gas concentration, etc.

[0061] The two parameters of temperature and humidity have a direct impact on the thermal comfort and physiological function of the human body. Extreme temperature and humidity not only cause discomfort, but also may cause heat stroke or other problems, such as heatstroke in high-temperature environment, or fatigue aggravation in high-humidity environment. The limited space of the power grid often accumulates harmful gases due to poor ventilation, which directly threatens the health of the operating object, such as toxic gases such as carbon monoxide and hydrogen sulfide, which can be fatal even at low concentrations. The passable width is a key physical parameter for determining whether the limited space of the power grid is sufficient to accommodate the operating object to perform safe operation, and the body width of the operating object needs to be considered to ensure that the operating object is not stuck or difficult to pass when moving in the limited space of the power grid, which relates to the feasibility of emergency evacuation and overall operation safety. The measured temperature, humidity and harmful gas content jointly determine the comfort and safety of the natural environment, and the measured passable width and the body width of the operating object directly affect the feasibility of the operation and the escape ability in emergency situations.

[0062] The embodiment of the present application fuses the natural environment data, the body width of the operating object and the natural environment definition data corresponding to the limited space, calculates the natural environment evaluation value to comprehensively evaluate whether the natural environment meets the operation requirements, and when the natural environment evaluation value exceeds the natural environment evaluation threshold, an alarm is issued to suspend the operation, and when the natural environment evaluation value does not exceed the natural environment evaluation threshold, the operating object is allowed to operate.

[0063] Optionally, the step of fusing the body width, the natural environment data and the natural environment definition data to obtain the natural environment evaluation 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 evaluation value, and the first formula is:

[0064]

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

[0066] In the embodiment of the present application, the natural environment evaluation value is calculated by the first formula, and the calculation formula of the natural environment evaluation value is designed as a complex function which comprehensively considers multiple environmental factors and actual operation space requirements, and the purpose is to provide a quantitative and comprehensive evaluation index for judging the safety of the natural environment of the limited space.

[0067] Temperature, humidity and harmful gas content are basic elements for evaluating the safety of the working environment, and are directly related to the health and safety of the operation object, and the difference between these parameters and their respective safety limit values is used to evaluate the suitability of the natural environment. Considering that the physical passability in the limited space is a key requirement for safe operation, the relationship between the measured passable width and the body width of the operation object is evaluated to ensure that the operation object can safely enter the limited space. By using the exponential function, the sensitivity of the measured value of the natural environment deviating from the limit value can be weighted, so that the natural environment evaluation value is more sensitive to the change of the measured value of the natural environment, especially when these measured values of the natural environment approach or exceed their safety limit values, the change can be well identified.

[0068] Through the first formula, multiple factors of the natural environment are comprehensively considered, and a unified evaluation value is used to quickly judge whether the minimum safety requirement for operation is met, which helps the operation manager to quickly make a decision on whether to suspend the operation, effectively prevents the occurrence of safety accidents, and protects the safety of the operation object.

[0069] In step S102, in the case that the natural environment evaluation value is greater than or equal to the natural environment evaluation threshold, an electric grid environment evaluation value is calculated based on limited space internal electric grid environment data in the operation environment data, and in the case that the electric grid environment evaluation value is greater than the electric grid environment evaluation threshold, an alarm prompt for suspending the operation is sent, wherein the limited space internal electric grid environment data includes electric grid voltage, electric grid equipment temperature and sound value.

[0070] In the embodiment of the present application, when the natural environment evaluation value is greater than or equal to the natural environment evaluation threshold value, that is, the case where the work object is allowed to work in the natural environment of the limited space, the power grid environment evaluation value is calculated based on the limited space internal power grid environment data in the work environment data, and whether the limited space internal environment has work risk is judged according to the power grid environment evaluation value. When the power grid environment evaluation value is greater than the power grid environment evaluation threshold value, it is considered that the limited space internal environment has work risk, at this time, the alarm prompt of suspending work is sent, and the work object is warned that it cannot work; when the power grid environment evaluation value is less than or equal to the power grid environment evaluation threshold value, it is considered that the limited space internal environment allows work, and the identity information and carrying equipment information of the work object are further checked.

[0071] The limited space internal power grid environment data includes power grid voltage, power grid equipment temperature and sound value. The limited space internal power grid environment data can be obtained by a special monitoring device. The voltage sensor is used to measure and monitor the voltage level in the power grid. The clamp ammeter is directly clamped on the cable, or other types of voltage detection devices are installed on different points in the circuit to monitor the power grid voltage. The temperature of the power grid equipment such as transformer and cable is monitored by using thermocouple or infrared thermometer. The sound value is usually obtained by using sound sensor (such as sound level meter).

[0072] The power grid voltage is the basis and key data in the power system, and its stability directly affects the operation of the whole power grid. Abnormal power grid voltage may cause equipment damage, operation failure and even safety accidents. The monitoring of power grid equipment temperature helps to prevent equipment failure and life shortening caused by overheating. Temperature anomaly is a direct indicator of possible equipment failure and overload. Sound value monitoring is used to monitor abnormal sound during operation of power grid equipment. These sounds are often early warnings of equipment failure, electrical failure or other problems. Although power grid voltage, power grid equipment temperature and sound value independently measure different physical quantities, they actually interact in the power grid system. For example, unstable power grid voltage may cause equipment overheating, and equipment overheating may cause material expansion and thus cause abnormal sound. At the same time, abnormal sound emitted by the equipment may be due to increased equipment friction caused by abnormal power grid voltage or power grid current.

[0073] The power grid environment evaluation threshold value is obtained from the database. The power grid environment evaluation threshold value is determined according to industry safety standards, regulatory requirements, historical data and experience, is set by analyzing potential risks and accident cases in a specific work environment, considers the safety margin of equipment and work object, and is determined in combination with literature materials, manufacturer recommended standards and experimental data to ensure that the power grid environment evaluation threshold value can effectively prevent accidents and health problems caused by power grid environment factors. The power grid environment evaluation threshold value is updated regularly to adapt to new developments and safety standards.

[0074] Optionally, the step of calculating the power grid environment evaluation value comprises: obtaining limited space internal power grid environment defining data corresponding to the limited space, wherein the limited space internal power grid environment defining data comprises: power grid defining voltage, power grid equipment defining temperature, and defining sound value; and fusing the limited space internal power grid environment data and the limited space internal power grid environment defining data to obtain the power grid environment evaluation value.

[0075] In the embodiment of the application, the calculation of the power grid environment evaluation value needs to obtain the limited space internal power grid environment defining data corresponding to the limited space and the limited space internal power grid environment data, and the power grid environment evaluation value is obtained by fusing the two.

[0076] The limited space internal power grid environment defining data corresponding to the limited space is obtained from a database, and the limited space internal power grid environment defining data is determined with reference to relevant industry standards, relevant safety specification standards, and company internal operation procedures, and in addition, the power grid equipment defining temperature and the defining sound value also need to be determined with reference to the operation specifications and safety operation guidelines provided by the equipment manufacturer.

[0077] Optionally, the step of fusing the limited space internal power grid environment data and the limited space internal power grid environment defining data to obtain the power grid environment evaluation value comprises: inputting the limited space internal power grid environment data and the limited space internal power grid environment defining data into a second formula to obtain the power grid environment evaluation value, and the second formula is:

[0078]

[0079] In the formula, Dp is the power grid environment evaluation value, dY is the power grid voltage, dW is the power grid equipment temperature, dS is the sound value, dcY is the power grid defining voltage, dcW is the power grid equipment defining temperature, dcS is the defining sound value, and e is a natural constant.

[0080] In the embodiment of the application, the limited space internal power grid environment data and the limited space internal power grid environment defining data are fused according to the second formula, the calculation formula of the power grid environment evaluation value is used to measure the deviation degree between the actual internal power grid environment data and the safety defining value, and an intuitive strategy is provided to evaluate the overall deviation of all key data. By using the exponential function form of the natural constant, the sensitivity of the power grid environment evaluation value to the deviation is enhanced. When the actual internal power grid environment data deviates from the safety range of the defining value, even a small change will cause the power grid environment evaluation value to increase significantly, so that the decision can be more sensitive and timely, thereby enhancing the effect of safety warning. The calculated power grid environment evaluation value is compared with the power grid environment evaluation threshold value stored in the database, so that it can be dynamically judged whether the current limited space internal power grid environment is suitable for operation.

[0081] The second formula considers three key data, i.e., the grid voltage, the device temperature and the sound value, ensures comprehensive evaluation of the internal grid environment of the limited space, and the comprehensive evaluation strategy helps monitor the operation of the grid from multiple aspects to prevent missing other potential risks due to abnormality of a single data.

[0082] In step S103, when the grid environment evaluation value is less than or equal to the grid environment evaluation threshold value, the identity information of the work object is obtained, and when the identity information does not match the specified identity information, it is determined that the work object is non-compliant, and an alarm prompt to suspend work is sent.

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

[0084] The identity information of the work object includes an employee number, a name, etc., and by comparing the identity information of the work object with the identity information of the specified work object of the limited space stored in the database, only when the identity information of the work object completely matches the specified identity information in the database, it is considered as a compliant work object, and this step ensures that only authorized work objects can enter the limited space for work.

[0085] In step S104, when the identity information matches the specified identity information, the device information carried by the work object is obtained, and when the device information does not match the specified device information, it is determined that the work object is non-compliant, and an alarm prompt to suspend work is sent.

[0086] In the embodiment of the present application, after the identity verification is passed, it is further checked whether the device information carried by the work object matches the device information required by the limited space in the database, the device information includes safety equipment information, tool information, etc., when the device information carried by the work object does not match the specified device information in the database, it is considered that the work object is non-compliant, and an alarm prompt to suspend work is sent, and the work object is not allowed to enter the limited space for work; only when the carried device information completely matches the specified device information in the database, the work object is allowed to enter the limited space for work. This step ensures that all work objects carry appropriate devices required to complete the work task, and reduces the safety risk.

[0087] In step S105, in the case where the device information matches the specified device information, a vital sign monitoring evaluation value is calculated based on the vital sign data of the work object, and in the case where the vital sign monitoring evaluation value is greater than a vital sign monitoring evaluation threshold value, it is determined that the vital sign of the work object is abnormal, and an alarm prompt to suspend the work is sent.

[0088] In the embodiments of the present application, in the case where the identity information of the work object and the carried device information both match the corresponding information in the database, the work object enters the limited space to work. After the work object enters the limited space, the vital sign data of the work object is monitored in real time, a vital sign monitoring evaluation value is calculated based on the vital sign data, and whether the vital sign of the work object is normal is determined according to the vital sign monitoring evaluation value. In the case where the vital sign monitoring evaluation value is greater than a vital sign monitoring evaluation threshold value, it is considered that the vital sign of the work object is abnormal, an alarm prompt is sent, and the work object is warned to suspend the work; in the case where the vital sign monitoring evaluation value is less than or equal to the vital sign monitoring evaluation threshold value, it is considered that the vital sign of the work object is normal, and the work object can continue to work.

[0089] The vital sign monitoring evaluation threshold value is obtained from the database, and the vital sign monitoring evaluation threshold value is usually obtained based on historical data, safety standards and specific work experience. First, by collecting and analyzing the vital sign data of the work object in historical work, the threshold value of the change of these data under different working conditions and its influence on health is studied. Then, combined with industry safety standards and medical recommended values, a threshold value suitable for a specific work environment is set, which can effectively indicate the health risk of the work object, thereby providing protection for work safety.

[0090] According to the natural environment data, reasonable vital sign state allowable deviation data, including the allowable fluctuation range of body temperature, heart rate and respiratory rate, are determined, the vital sign state boundary data of the work object is obtained from the database, the measured vital sign data is fused with the vital sign state boundary data, and a vital sign monitoring evaluation value is generated. The vital sign monitoring evaluation value considers the difference between the actual measurement and the predetermined standard to determine whether the current physiological state of the work object is within the safe range. According to the vital sign monitoring evaluation value, it is determined whether the work object can continue to work. If the vital sign monitoring evaluation value exceeds the vital sign monitoring evaluation threshold value, it is recommended to stop working and take appropriate measures; if it does not exceed the vital sign monitoring evaluation threshold value, it can continue to work. Real-time monitoring of vital sign data can quickly identify work objects at risk of health, timely send alarm prompts, and take measures such as evacuation or provide medical assistance, thereby reducing the risk of serious health problems and accidents.

[0091] Optionally, the step of calculating the sign monitoring evaluation value comprises: determining sign state allowable deviation data of the work object based on the natural environment data, wherein the sign state allowable deviation data comprises a body temperature allowable deviation value, a heart rate allowable deviation value, and a respiration rate allowable deviation value; obtaining sign state boundary data corresponding to the work object, wherein the sign state boundary data comprises a body temperature boundary value, a heart rate boundary value, a respiration rate boundary value, and a water evaporation boundary value; and fusing the sign data and the sign state boundary data to obtain the sign monitoring evaluation value, wherein the sign data comprises a body temperature measured value, a heart rate measured value, a respiration rate measured value, and a water evaporation measured value.

[0092] In the embodiment of the present application, the calculation of the sign monitoring evaluation value is first based on the natural environment data to determine the sign state allowable deviation data of the work object, and then the sign state allowable deviation data is combined to fuse the sign data and the sign state boundary data to obtain the sign monitoring evaluation value.

[0093] The sign state boundary data is obtained from a database, and the sign state boundary data sets the safety threshold of the body temperature, heart rate, respiration rate, and water evaporation of the work object. The sign state boundary data is usually obtained by monitoring the body temperature, heart rate, respiration rate, and water evaporation of the work object under the condition of simulating a limited space in a controlled environment to determine the physiological parameters for safe work. Considering that the physiological responses of each work object may be different, by setting personalized sign state boundary data, the health of each work object can be more accurately protected.

[0094] The sign data comprises a body temperature measured value, a heart rate measured value, a respiration rate measured value, and a water evaporation measured value, wherein the body temperature measured value is measured by an electronic thermometer, the heart rate measured value is obtained by a chest strap or wrist strap type heart rate monitor, the respiration rate measured value is measured by sensing the expansion and contraction of the chest cavity by a respiration rate monitoring device, and the water evaporation measured value is obtained by monitoring the water evaporation rate on the skin surface by a water evaporation sensor. By collecting the body temperature, heart rate, respiration rate, and water evaporation data of the work object in real time, the physiological state of the work object in a specific working environment can be known. If the sign monitoring evaluation value exceeds the sign monitoring evaluation threshold value, it indicates that the work object may face the risk of health abnormalities or excessive physiological stress, and work should be stopped immediately. If the sign monitoring evaluation value does not exceed the sign monitoring evaluation threshold value, it indicates that the physiological state of the work object is stable, and work can be safely continued.

[0095] Body temperature is one of the basic vital signs, reflecting the body's heat balance state. In extreme environments (such as high temperature or cold conditions), the monitoring of body temperature is particularly important, as it can indicate whether the body is properly regulating body temperature; heart rate reflects the load on the heart and the body's response to the workload, and changes in heart rate under physical labor or stress conditions can indicate the stress on the cardiovascular system and the body's stress response; respiratory rate is an important indicator of respiratory function and body metabolism level, and monitoring of 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, and monitoring water evaporation can help prevent dehydration and heat exhaustion in high temperature environments or when wearing protective clothing. At the same time, body temperature, heart rate, respiratory rate and water evaporation data are interrelated, body temperature regulation is closely related to water evaporation, when the environmental temperature rises or the body's labor intensity increases, the body dissipates heat by increasing sweat evaporation to maintain stable body temperature. When body temperature rises, heart rate usually also increases, as the body needs more blood flow to help dissipate heat. In situations of high labor intensity or environmental stress, heart rate and respiratory rate usually increase simultaneously, as the body tries to cope with increased metabolic demand by increasing oxygen intake and carbon dioxide output. In hot or dry environments, as water evaporation rate increases, respiratory rate may need to be increased to regulate body water and temperature.

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

[0097]

[0098] wherein TzP is the vital sign monitoring evaluation value, sTw is the measured value of body temperature, sXw is the measured value of heart rate, sHw is the measured value of respiratory rate, SfZ is the measured value of water evaporation, cTw is the boundary value of body temperature, cXw is the boundary value of heart rate, cHw is the boundary value of respiratory rate, cfZ is the boundary value of water evaporation, 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 the embodiment of the present application, the sign data and the sign state definition data are fused according to the third formula to obtain a sign monitoring evaluation value. The calculation formula of the sign monitoring evaluation value is to normalize the difference between the sign measured value and the sign state definition value within the allowed deviation range, so that the deviation degree of different data can be compared and accumulated on the same scale to provide a unified measurement standard. The third formula uses a logarithmic function for weighting and conversion, which can reduce the influence of abnormal values and prevent extreme data from causing excessive deviation of the evaluation result. The logarithmic conversion can make the evaluation value change more smoothly and avoid sharp changes in the evaluation value caused by extreme deviation of individual data. The design of this part is to particularly emphasize the influence of water evaporation value, and the change of water evaporation rate is crucial to body temperature regulation and body water balance, especially in hot environments or high-intensity labor. The use of an exponential function to enhance its influence is to ensure that even small changes can be properly reflected in the overall evaluation, especially when evaluating the risk related to heat stress, which can play a big role.

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

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

[0102]

[0103] wherein 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; and the sign state allowed deviation data corresponding to the comparison coefficient with the smallest value is taken as the sign state allowed deviation data of the work object.

[0104] In the embodiment of the present application, to determine the sign state allowable deviation data of the work object, firstly, a mapping table of the sign state allowable deviation data and the natural environment matching data is obtained, and then each natural environment matching data in the mapping table and the natural environment data are input into the fourth formula respectively to calculate a plurality of comparison coefficients, and the sign state allowable deviation data corresponding to the comparison coefficient with the smallest value is taken as the sign state allowable deviation data of the work object.

[0105] The mapping table contains the correlation between the natural environment matching data and the sign state allowable deviation data, and these matching data include matching temperature, matching humidity, matching harmful gas content and matching passable width, which are all key environmental factors affecting the health of the work object. By comparing the measured natural environment data with the natural environment matching data in the mapping table, the comparison coefficient is obtained. This process aims to find the standard configuration closest to the current natural environment condition, ensuring the accuracy and applicability of the evaluation. According to the comparison coefficient, the minimum value is selected, i.e. the deviation data closest to the actual natural environment condition is selected, ensuring that the sign state allowable deviation can best reflect the actual risk and needs under the current natural environment. According to the specific conditions of each work environment, the safety standard is adjusted, making the safety management more accurate and personalized, and improving the effectiveness of the protective measures.

[0106] The mapping table of the sign state allowable deviation data and the natural environment matching data is obtained from the database, and the mapping table is established through professional safety evaluation, experimental research and historical data analysis. First of all, a team of safety experts and medical experts will determine the allowable deviation range of the sign state under various environmental conditions according to experimental observations and historical work data under different natural environments. Then, these data are standardized and matched with the corresponding natural environment conditions through statistics and analysis, forming the mapping table. Finally, these mapping tables are entered into a specially designed database for real-time matching and evaluation before the work object actually works, ensuring that the work object can safely adapt to the specific work environment.

[0107] In the calculation formula of the comparison coefficient, i.e. the fourth formula, the square root is used to reduce the influence of extreme deviation values. The square root can make the influence of deviation more moderate, preventing extreme abnormal values of a single variable from causing excessive influence on the overall comparison coefficient. By dividing by the natural environment matching data, i.e. the ideal or target value of each natural environment data, the difference is normalized, which can ensure that the deviation of different natural environment parameters in its own magnitude contributes to the comparison coefficient, so that the result will not be biased due to the difference in parameter unit or magnitude. All normalized square root deviations are accumulated, which can comprehensively consider the influence of each natural environment data on the suitability of the current working condition. This comprehensive consideration is to evaluate the overall consistency between the actual natural environment condition and the preset standard.

[0108] The steps provided by the operation alarm method of the power grid limited space can ensure that only authorized operation objects and equipment can enter the limited space by obtaining identity information of the operation object, obtaining equipment information carried by the operation object in the case that the identity information does not match specified identity information, and judging whether the equipment information matches specified equipment information, for the operation object that has entered the limited space to perform an operation task, by continuously monitoring vital sign data, calculating a vital sign monitoring evaluation value based on the vital sign data of the operation object, and judging whether the operation object is suitable to continue the operation according to the vital sign monitoring evaluation value.

[0109] The embodiment of the present application ensures that the operation object is allowed to perform the operation only when all safety conditions are met through accurate data analysis, significantly reduces risks and potential accidents in work, all decisions are based on real-time data and preset safety standards, human errors and subjective judgment interference are reduced, real-time updated operation environment data and characteristic data of the operation object improve response capability to emergencies, ensure that the operation can continue under the premise of safety, and unnecessary work interruption caused by safety problems is reduced. In the operation process, once abnormal environment data and abnormal characteristic data are monitored, an alarm prompt is immediately issued to alert the operation object to suspend the operation, and corresponding measures are taken to prevent safety accidents. Further, the technical problem that environment data and vital sign data of the operation object cannot be monitored in real time in the related art, resulting in untimely alarm, is solved.
