Description

Technical Field

[0001] The present invention relates to the field of real-time monitoring technology, and in particular to a method and system for real-time monitoring of the working status of operators. Background Art

[0002] As the scale and complexity of modern engineering construction continue to expand, the demand for engineering safety is also increasing. At present, traditional safety management methods mainly rely on manual supervision, such as safety officers patrolling the work area to supervise the work process of operators.

[0003] However, this method is not only costly and inefficient, but also slow to respond to sudden safety accidents or potential safety hazards, and there is a problem of delayed response. In addition, manual supervision can often only monitor obvious and one-sided risk factors, such as the identity information of the operator and the wearing status of the operator's protective equipment, while ignoring other potential risks, such as the physical condition of the operator and subtle changes in the working environment. This makes the judgment of operational risks inaccurate, and thus it is impossible to safely and accurately monitor high-risk operators to reduce the accident rate. Summary of the invention

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] In the description of the present invention, it should be understood that the terms “first” and “second” are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0049] Embodiment 1:

[0050] Reference Figure 1 , is a flowchart of the operation steps of a method for real-time monitoring of the operation status of an operator provided by an embodiment of the present invention, the method at least comprising the following steps:

[0051] Step S1: During operation, the current physical condition data and current working environment data of the operator are obtained;

[0052] In this embodiment, a number of air pressure sensors, wind speed sensors and temperature sensors are deployed in the working area to obtain the current working environment data of the workers, and the current physical state data of the workers during work is collected through physiological monitoring equipment; wherein, the working environment data includes ambient air pressure value, ambient wind speed value and ambient temperature value; the physical state data includes pulse pressure, body temperature and respiratory rate; the physiological monitoring equipment includes but is not limited to heart rate monitor, blood oxygen monitor, body temperature monitor.

[0053] Step S2: determining the environmental assessment value of the current working environment and the floating threshold value of the physical state data of the operator in the current working environment according to the current working environment data;

[0054] In this embodiment, the calculation formula of the environmental assessment value of the current working environment is:

[0055]

[0056] Wherein, A is the working environment assessment value; Q is the air pressure deviation, which is the difference between the actual ambient air pressure value of the current working environment and the preset air pressure limit value; F1 is the actual ambient wind speed value of the current working environment; F0 is the preset wind speed limit value of the current working environment; W is the temperature deviation, which is the difference between the actual ambient temperature value of the current working environment and the preset temperature limit value;

[0057] In this embodiment, the ambient air pressure is the gravity of the gas applied per unit area, usually expressed in Pascals (Pa) or millimeters of mercury (mmHg). It affects the concentration distribution of the gas and the safety in the working environment, and can be measured in real time by a pressure sensor. Q is the absolute value of the difference between the ambient air pressure and the air pressure limit value. The ambient wind speed is the speed of air flow, usually expressed in meters per second (m / s) or kilometers per hour (km / h). The wind speed affects the ventilation effect in the workplace and the dilution of chemical substances. When working in a dangerous environment at high altitudes, it affects the physical stability of the workers, thereby greatly affecting the safety of the workers. A wind speed sensor is used for real-time monitoring. The ambient temperature refers to the temperature of the surrounding air, usually expressed in degrees Celsius. The temperature affects the comfort of workers and the working efficiency of certain equipment. The ambient temperature is measured in real time using a temperature sensor (such as a thermocouple or a thermometer). W is the absolute value of the difference between the ambient temperature and the temperature limit value.

[0058] In this embodiment, determining the floating threshold of the physical status data of the operator in the current working environment includes:

[0059] Calculate a number of matching coefficients based on the current working environment data and different working environment data preset in the database; wherein each preset working environment data corresponds to a floating threshold value of the body state data;

[0060] In this embodiment, the calculation formula of the matching coefficient is:

[0061]

[0062] Where D is the matching coefficient; Q1 is the ambient air pressure value of the current operating environment data; Q p is the ambient air pressure value of the preset working environment data in the database; F1 is the ambient wind speed value of the current working environment data; F p is the ambient wind speed value of the preset working environment data in the database; W1 is the ambient temperature value of the current working environment data; W p is the ambient temperature value of the preset working environment data in the database; e is a natural constant;

[0063] According to a number of matching coefficients, the preset working environment data matched by the minimum matching coefficient is selected, and according to the preset working environment data matched by the minimum matching coefficient, the floating threshold value of the physical state data of the operator in the current working environment is determined.

[0064] In this embodiment, the different working environment data preset in the database can be set by technical personnel based on the historical working environment data under different working conditions according to technical experience or statistical analysis methods, and the floating threshold of the physical condition data corresponding to the preset working environment data can also be set by technical personnel based on the physical condition data of the workers under different historical working environment data according to technical experience or statistical analysis methods.

[0065] Exemplarily, the ambient air pressure, ambient wind speed and ambient temperature directly affect the body state data of the human body, such as pulse pressure, respiratory rate and body temperature. Therefore, if the ambient air pressure changes, it may affect blood circulation. For example, in high altitude areas, the decrease in ambient air pressure may cause the blood oxygen content to decrease, thereby inducing an increase in heart rate, resulting in changes in pulse pressure, and the human body may need to consume more energy to maintain body temperature, which is easy to cause the body temperature to drop or become unstable. Under low ambient air pressure, the respiratory rate usually increases in order to obtain more oxygen, and there will be a phenomenon of shortness of breath. When the ambient wind speed is high, the human body may feel the influence of cold wind, causing vasoconstriction, thereby changing the heart burden and pulse pressure. When the ambient wind speed is high, the speed of evaporation and heat dissipation on the body surface is accelerated, which is easy to cause a decrease in body temperature, especially in a cold environment, affecting the stability of body temperature, and may make breathing difficult or accelerated, so that the respiratory rate increases. If the ambient temperature is high, vasodilation can cause the pulse pressure to drop. On the contrary, if the ambient temperature is low, vasoconstriction may cause the pulse pressure to rise. The higher the ambient temperature, the higher the body temperature and the faster the respiratory rate, while the lower the ambient temperature, the lower the body temperature and the lower the respiratory rate.

[0066] Step S3: Calculating the operator's physical condition assessment value according to the operator's current physical condition data and the physical condition data floating threshold;

[0067] In this embodiment, the calculation formula of the operator's physical condition assessment value is:

[0068]

[0069] Among them, B is the physical condition assessment value of the operator; sMb is the pulse pressure of the current physical condition data; sTw is the body temperature of the current physical condition data; sHx is the respiratory rate of the current physical condition data; cMb is the preset normal pulse pressure; cTw is the preset normal body temperature; cHx ​​is the preset normal respiratory rate; ΔMb is the pulse pressure floating threshold of the physical condition data floating threshold; ΔTw is the body temperature floating threshold of the physical condition data floating threshold; ΔHx is the respiratory rate floating threshold of the physical condition data floating threshold.

[0070] In this embodiment, sMb refers to the difference between systolic pressure and diastolic pressure, which reflects the function of blood circulation. The normal range is generally 40-60 mmHg, which can be measured by an automatic blood pressure monitor or a heart rate monitoring device. sTw refers to the temperature of the human body. The normal body temperature range is usually between 36.1°C and 37.2°C. The deviation of sTw may indicate infection, shock or other diseases. It can be measured using electronic thermometers, infrared thermometers and other equipment. sHx refers to the number of respirations per minute. The normal respiratory rate of an adult is generally between 12 and 20 times / minute, which can be measured by a respiratory monitoring device.

[0071] sMb, sTw and sHx are important vital signs of the human body. During the work process, by real-time monitoring of these data of the staff's body, the physical state of the staff can be understood in real time, and the health status of the staff can be reflected in time, reducing emergencies during the work process, and timely discovering physical abnormalities (such as excessive fatigue or physical discomfort). When physical abnormalities are found, the work is stopped immediately to reduce the probability of accidents caused by poor physical condition. After understanding the physical condition of the staff, the work arrangement can be flexibly adjusted according to their health status to ensure work efficiency and safety, and improve the level of work safety management of the staff;

[0072] Set cMb, cTw and cHx as the baseline, calculate the difference between the deviation of the physical condition of the personnel and the reference standard, and if B is large, issue an alarm and stop the operation; otherwise, allow the operation to continue. Setting the reference data as the health standard can provide enterprises with a clear basis for evaluating the physical condition of the staff. Through deviation detection, it can identify whether the staff is in a dangerous state at an early stage, take measures in real time, and make the staff work in the most suitable state, enhance the staff's confidence in the safety of the working environment, and help create a safe working atmosphere;

[0073] This formula comprehensively evaluates the physical condition of personnel by calculating the deviations between sMb, sTw and sHx and their reference values. The deviation value of each parameter is standardized (divided by the corresponding allowable deviation value) to ensure that parameters of different dimensions can be effectively compared. The absolute value in the formula ensures that the deviation, whether positive or negative, can reflect the impact on the physical condition, avoiding misjudgment caused by directionality. By comprehensively considering the influence of multiple physiological parameters, it can comprehensively reflect and evaluate the physical condition of staff members, and can be compared between different individuals in a more systematic and consistent manner. The setting of the allowable deviation value makes the detection more flexible and can be adjusted according to the environment and individual differences, making the evaluation more personalized and accurate, adapting to the needs of diverse working environments, and fully ensuring the safety of staff members.

[0074] Step S4: Calculate the operator's operation risk assessment value during operation based on the operator's operation environment assessment value and physical condition assessment value during operation, and determine the operator's subsequent operation status based on the operator's operation risk assessment value during operation; the operation status includes: stop operation and continue operation.

[0075] In this embodiment, the calculation formula of the operation risk assessment value of the operator during the operation is:

[0076] C = c1*A+c2*B;

[0077] Among them, C is the job risk assessment value; c1 is the weight factor of the job environment assessment value; c2 is the weight factor of the physical condition assessment value.

[0078] In this embodiment, according to the operation risk assessment value of the operator during the operation, the subsequent operation status of the operator is determined, including:

[0079] When the operation risk assessment value of the operator during the operation is less than the preset risk assessment threshold, the subsequent operation status of the operator is determined to be continued operation;

[0080] When the operation risk assessment value of the operator during the operation is greater than or equal to the preset risk assessment threshold, the subsequent operation status of the operator is determined to be stopped operation.

[0081] In this embodiment, refer to Figure 2 :A flow chart of pre-operation steps of a method for real-time monitoring of the operating status of an operator provided by an embodiment of the present invention, wherein the method further comprises the following steps:

[0082] Step A1: Before the operation, obtain the current identity information data and current protective equipment wearing data of the operator;

[0083] In this embodiment, the current identity information data of the operator can be obtained through a biometric device, and the operator's protective equipment can be identified and analyzed through a three-dimensional scanner, CAD software, or computer vision technology to obtain the operator's current protective equipment wearing data.

[0084] In this embodiment, the biometric device can be a face recognition device, an iris recognition device, a fingerprint recognition device or a palm print recognition device, wherein the face recognition device uses facial feature points for recognition, captures facial images through a camera and compares them with images in a database, and is often used for security monitoring and identity authentication; the iris recognition device confirms identity by scanning the unique pattern of the iris; the fingerprint recognition device confirms identity by scanning and analyzing the uniqueness of the fingerprint; and the palm print recognition device identifies and compares the lines and size of the palm to identify the identity.

[0085] Step A2: According to the current identity information data of the operator, the identity information of the operator is compared to obtain the identity information comparison result; according to the current protective equipment wearing data of the operator, the protective equipment wearing assessment value of the operator is calculated;

[0086] In this embodiment, the calculation formula of the protective equipment wearing assessment value of the operator is:

[0087]

[0088] Wherein, F is the protective equipment wearing assessment value; sXZ is the equipment shape; cXZ is the equipment reference shape; sBF is the equipment surface reflectivity; cBF is the equipment surface reference reflectivity; sBC is the equipment surface roughness; cBC is the equipment surface reference roughness; σ(sXZ,cXZ) is the similarity function of sXZ and cXZ;

[0089] In this embodiment, sXZ refers to the geometric shape of the protective equipment. The shape of the equipment can be identified and analyzed by a 3D scanner, CAD software or computer vision technology. 3D scanning can accurately capture the shape of the equipment. The shape is represented by extracting the boundary points (contour points) of the shape. A parameterized curve (such as a polynomial or spline curve) is used to describe the boundary of the shape. The shape of the equipment can be quantified. σ(sXZ, cXZ) is the similarity function between sXZ and cXZ. The cosine similarity is used to calculate the similarity between sXZ and cXZ. Knowing sXZ can evaluate whether the protective equipment can fully cover the body part for which it is designed. For example, whether the shape of a helmet or goggles is consistent with the shape of a standard wearing device to ensure that the helmet, goggles, etc. are suitable for wearing. SBC refers to the unevenness of the equipment surface, which is obtained by measuring the surface features through a surface roughness meter, laser scanning or microscope. sBF refers to the ability of the equipment surface to reflect light, which is measured using a spectral reflectometer, which can accurately measure the reflectivity of different wavelengths. By understanding sBC and sBF, it is possible to determine whether the surface information of the currently tested wearable device is consistent with that of the standard wearable device, thereby determining whether the external wearable device worn by the operator is qualified. By comparison, it is ensured that all operators wear protective equipment that meets safety standards, effectively preventing safety accidents caused by unqualified wearing of protective equipment, and through the detection feedback mechanism, it can remind operators, emphasize the importance of protective equipment, and improve operators' awareness of and compliance with safety standards.

[0090] Step A3: Based on the identity information comparison result and the protective equipment wearing assessment value, determine whether the operator meets the operating requirements. If the operator meets the operating requirements, generate a first prompt message to allow the operator to operate. If the operator does not meet the operating requirements, generate a second prompt message not to allow the operator to operate.

[0091] In this embodiment, judging whether the operator meets the operation requirements according to the identity information comparison result and the protective equipment wearing assessment value includes:

[0092] When the identity information comparison result is an identity match, and the protective equipment wearing assessment value is less than the preset protective equipment wearing assessment threshold, it is determined that the operator meets the operating requirements, and a first prompt information is generated to allow the operator to operate;

[0093] Otherwise, it is determined that the operator does not meet the operating requirements, and a second prompt message is generated that does not allow the operator to operate.

[0094] In a preferred embodiment, the protective equipment wearing data and protective equipment wearing reference data of the operator are σ(sXZ, cXZ) is 0.9, sBC is 3μm, sBF is 89%, cBC is 2.8μm, cBF is 90%, and the protective equipment wearing assessment value is calculated to be 4.29, and the protective equipment wearing assessment threshold is 3.75. Since the protective equipment wearing assessment value is greater than the protective equipment wearing assessment threshold, the operator's protective equipment is qualified, and the qualified operator is allowed to work, and during the operation, the working environment and the operator's physical condition are monitored in real time;

[0095] In the calculation formula of the environmental assessment value of the current working environment, Q is 7hPa, F1 is 3m / s, F0 is 4m / s, W is 3℃, the reference threshold of air pressure deviation is 10hPa, and the reference threshold of temperature deviation is 5℃. When Q and W are both less than the corresponding reference thresholds, and F1 is less than F0, the calculated working environment assessment value is 2.07, and the working environment assessment threshold is 2.41. When the working environment assessment value is less than the working environment assessment threshold, the current working environment can continue to work;

[0096] In the calculation formula of the matching coefficient, Q1 is 1010hPa, Q p is 1013hPa, F1 is 4m / s, F p is 6m / s, W1 is 20℃, W p The temperature is 23℃, and the calculated matching coefficient is 16.93, that is, the minimum matching coefficient is 16.93. The matching coefficient corresponds to ΔMb of 10mmHg, ΔTw of 1℃, and ΔHx of 5 times / minute.

[0097] In the operator's physical condition data, sMb is 45 mmHg, sTw is 37.2°C, and sHx is 17 times / minute. In the operator's physical condition reference data, cMb is 50 mmHg, cTw is 37°C, and cHx is 20 times / minute. In the operator's physical condition data floating threshold, ΔMb is 10 mmHg, ΔTw is 1°C, and ΔHx is 5 times / minute. The operator's physical condition assessment value is calculated to be 1.14, and the operator's physical condition assessment threshold is 1.73. When the operator's physical condition assessment value is less than the operator's physical condition assessment threshold, the operator's physical condition can continue to work;

[0098] In the operation risk data, the operation environment assessment value is 2.07, the operator's physical condition assessment value is 1.14, c1 is 0.5, c2 is 0.5, the calculated operation risk assessment value is 1.61, and the operation risk assessment threshold is 2.07. When the operation risk assessment value is less than the operation risk assessment threshold, the current working environment is risk-free and the operator can continue to work.
