[0052] The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0054] The present invention provides a safety evaluation method. Figure 1 A schematic diagram of the implementation process of a safety evaluation method provided in an embodiment of the present application is shown as follows: Figure 1 As shown, the method mainly includes the following steps:

[0056] Step S120: determining a comprehensive safety factor based on at least one of the first safety factor and / or the second safety factor;

[0057] Step S130: Determine the safety status information of the target system based on the comprehensive safety factor.

[0058] The security assessment method involved in the embodiments of the present application can be executed by the target system, or can be executed by a terminal that establishes a communication connection with the target system. If the security assessment method is executed by the target system, the target system includes a processor connected to each sensor in the target system, or the target system includes a terminal. The terminal can be any mobile terminal or fixed terminal, such as, but not limited to, a mobile communication device, a computer, a server, or a wearable device.

[0059] Here, the water pump equipment includes but is not limited to at least one of the following: a vane pump, a positive displacement pump, a centrifugal pump, a multi-stage pump, a booster pump and a water pump.

[0060] Here, the air cooler includes but is not limited to at least one of the following: a forced draft air cooler, an induced draft air cooler, and a natural ventilation air cooler.

[0061] In one embodiment, the target system can be any system including water pump equipment and / or air cooler equipment. For example, the target system can be a blast furnace circulating cooling water system. The target system includes, but is not limited to, at least one of the following: an evaporative air cooler, a degassing tank, a water pipe, a spray circulating water pump, a pressure water pump, a drain pipe, and a make-up water pump.

[0062] Here, the first safety factor is the safety factor of the water pump equipment; it is determined based on the operating parameters of the various components of the water pump equipment and is used to indicate the health status of each water pump equipment. Components include, but are not limited to, at least one of the following: an impeller, a pump body, a pump shaft, bearings, a sealing gland, and a stuffing box. Operating parameters include, but are not limited to, at least one of the following: operating parameters of the impeller, operating parameters of the pump shaft, and operating parameters of the bearings.

[0063] Exemplarily, bearing operating parameters include bearing vibration and / or bearing temperature. Bearing vibration can be acquired using a vibration-temperature integrated sensor, and bearing temperature can be acquired using a temperature sensor. Impeller operating parameters include theoretical flow and / or leakage flow. The theoretical flow indicates the flow through the impeller, a component of the pump. The leakage flow indicates the portion of the theoretical flow out of the impeller that flows back to the impeller inlet and out of the pump.

[0064] Here, the second safety factor is the safety factor of the air cooler group; the second safety factor is determined according to the operating parameters of the air cooler; and the second safety factor is used to indicate the health status of each air cooler device.

[0065] For example, the operating parameters of the air cooler include, but are not limited to, the air cooler inlet water temperature and the air cooler outlet water temperature. The air cooler inlet / outlet water temperatures can be collected using a temperature sensor.

[0066] Here, the comprehensive safety factor is the safety factor of the target system, used to indicate the health status of the target system, including the water pump equipment and the air cooler group. The comprehensive safety factor can be divided into at least one comprehensive safety factor interval, and different comprehensive safety factor intervals correspond to different safety status information.

[0067] Here, the security status information is used to indicate the security status of the target system. Exemplarily, the security status information is information indicating the security status of at least one of N security statuses of the target system, where N is an integer greater than 0.

[0068] Exemplarily, the comprehensive safety factor includes M comprehensive safety factor intervals, for example, the comprehensive safety factor includes the 1st to Mth comprehensive safety intervals; the security status information is used to indicate N security states of the target system, for example, the security status information is used to indicate the 1st to Nth security states; wherein M and N are both integers greater than 0. The terminal stores a correspondence between the M comprehensive safety factor intervals and the N security states; if the terminal obtains the comprehensive safety factor of the target system, it can determine the security state corresponding to the comprehensive safety factor based on the comprehensive safety factor and the correspondence. For example, the terminal determines that the obtained comprehensive safety factor belongs to the second comprehensive safety factor interval, and based on the correspondence, determines that the security state corresponding to the second comprehensive safety factor is the second security state; the terminal determines that the security state information of the target system is security state information indicating the second security state.

[0069] In one embodiment, the security status information includes: first security status information indicating a first security status, second security status information indicating a second security status, and third security status information indicating a third security status. The first security status information indicates that the target system is in a healthy state of normal operation; the second security status information indicates that the target system is in a sub-healthy state, indicating that the target system can operate but requires debugging and maintenance; and the third security status information indicates that the target system is in an unhealthy state, indicating that a fault has occurred and the target system cannot operate and requires troubleshooting.

[0070] In some embodiments, the terminal collects the bearing temperature and vibration values ​​of multiple water pump devices in real time based on the target system's integrated vibration and temperature sensor, and then determines the first safety factor of the corresponding water pump device based on the bearing temperature and vibration values. The terminal collects the inlet and outlet water temperatures of multiple air coolers in real time based on the target system's temperature sensor, and then determines the second safety factor of the air cooler group based on the difference between the inlet and outlet water temperatures. The terminal determines the comprehensive safety factor of the target system based on the multiple first and second safety factors. If the comprehensive safety factor indicates that the target system is in the third safety state, the safety state information of the target system is determined to be the third safety state information, reminding the user that timely maintenance and troubleshooting are required to avoid damage to the target system equipment that causes property loss, and to prevent safety accidents that pose a life threat to the user.

[0071] In this way, the target system's comprehensive safety factor is determined based on the first safety factor of the water pump equipment and the second safety factor of the air cooler group. This comprehensive safety factor can be used to determine whether the target system's operational safety is abnormal. Promptly determining and evaluating the safety of the target system's operation helps users understand the safety status of the target system. Furthermore, comprehensive consideration of equipment such as the water pump and air cooler group in the target system improves the accuracy and effectiveness of the comprehensive safety factor.

[0072] In some embodiments, obtaining a first safety factor of at least one water pump device of the target system in step S110 includes:

[0073] Obtaining a static health coefficient of at least one of the water pump devices and a dynamic health coefficient of the water pump device; wherein the static health coefficient is determined based on a theoretical life value and a remaining life value of the water pump device; and the dynamic health coefficient is determined based on a coefficient change rate of at least one component of the water pump device;

[0074] The first safety factor is determined based on the dynamic health factor and the static health factor.

[0075] In one embodiment, obtaining the static health coefficient of the water pump equipment includes:

[0076] Determining a first value based on a difference between a theoretical life value of the water pump device and a remaining life value of the water pump device;

[0077] The static health factor of the water pump equipment is determined based on a ratio of the first value to the theoretical life value.

[0078] For example, a method for obtaining the static health coefficient of the water pump equipment is: Among them, the θ 静 is the static health coefficient; the L 理 is the theoretical life of the water pump equipment; 剩 It is the remaining life value of the water pump equipment.

[0079] Here, the dynamic health coefficient is determined based on a coefficient change rate of at least one component of the water pump equipment; and the coefficient change rate is determined based on a measured value and a reference value of an operating parameter of at least one corresponding component.

[0080] In some embodiments, as Figure 2 As shown, obtaining the dynamic health coefficient of at least one of the water pump devices includes:

[0084] Step S240: Determine the dynamic health coefficient based on the first health-related value, the second health-related value, and the product of the coefficient change rate of at least one component.

[0085] Here, the first health-related value is a first-class assessment value set by a first-class user based on the impact of at least one component on the health status of the water pump equipment. The first-class user includes operators of the target system. The first-class user determines the first health-related value based on the importance of the component to the health status of the water pump equipment and / or the frequency of obtaining real-time operating parameters of the component.

[0086] In one embodiment, the first health-related value is greater than or equal to 0 and less than or equal to 1. The first health-related values ​​of different components may be the same or different.

[0087] Here, the first health-related value may also be a historical experience value. The first type of user determines the first health-related value based on historical experience.

[0088] Here, the magnitude of the first health-related value is positively correlated with the importance of the component; and / or the magnitude of the first health-related value is positively correlated with the frequency of acquisition.

[0089] Here, the second health relevance value is a second-type assessment value set by a second-type user based on the impact of at least one component on the health status of the water pump equipment. The second-type user includes experts in the field to which the target system belongs. The experts determine the second health relevance value based on their industry knowledge in this field.

[0090] In one embodiment, the second health-related value is greater than or equal to 0 and less than or equal to 1. The second health-related values ​​of different components may be the same or different.

[0091] In one embodiment, the first type of users determine the first health association value based on the importance of the components to the health status of the water pump equipment and further combine it with a genetic algorithm; the second type of users determine the second health association value based on the industry knowledge in this field and further combine it with a genetic algorithm.

[0092] Here, a genetic algorithm is a computational model that simulates the biological evolutionary process of natural selection and genetics, as described in Darwin's theory of evolution. It is a method for searching for optimal solutions by simulating the natural evolutionary process. Using a genetic algorithm, the optimal correlation value for each component can be calculated from the correlation values ​​of multiple components. This optimal correlation value serves as the first health correlation value for that component. Similarly, the genetic algorithm can also be used to obtain the second health correlation value for each component.

[0093] Here, the measured value is the actual value of the component's operating parameter; the reference value is the value the component's operating parameter should theoretically reach. For example, if the operating parameter is a bearing temperature, the measured value is the actual bearing temperature, and the reference value is the theoretical bearing temperature. The temperature reference values ​​for different bearing models can be the same or different.

[0094] In one embodiment, determining the coefficient change rate of the component based on the measured value and reference value of the operating parameter of at least one component in step S230 includes:

[0095] determining a second value based on a difference between a measured value of at least one of the components and a reference value;

[0096] Based on the ratio of the second value to the measured value, a coefficient change rate of the component component is determined.

[0099] determining a third value based on a product of the first health-related value, the second health-related value, and the coefficient change rate of at least one of the component components;

[0100] The dynamic health coefficient is determined based on the sum of the first to nth third numerical values; wherein n is a positive integer.

[0101] For example, one way to determine the dynamic health coefficient is: 动 =α1β1Δ 变1 +α2β2Δ 变2 +...+α n β n Δ 变n ; wherein, the α n is the first health-related value of the nth component; the β n is the second health-related value of the nth component; the Δ 变n is the coefficient change rate of the nth component; the θ 动 is the dynamic health coefficient. If the value of the dynamic health coefficient is greater than 1, set θ动 =1.

[0102] In this way, the dynamic health coefficient of the water pump equipment is determined based on the fourth values ​​of the 1st to nth components of at least one water pump equipment, and the impact of each component on the health status of the water pump equipment is fully considered; and each component takes into account the different evaluation values ​​of different categories of users, further improving the accuracy and reliability of the dynamic health coefficient.

[0103] In one embodiment, determining the first safety factor based on the dynamic health factor and the static health factor of at least one of the water pump devices includes:

[0104] determining a fourth value of the water pump device based on a sum of the dynamic health coefficient and the static health coefficient of the water pump device;

[0105] Based on the difference between the first constant and the fourth value, the first safety factor is determined. For example, the first constant is 1, and a method for determining the first safety factor is: H = 1-(θ 静 +θ 动 ); wherein, the θ 动 is the dynamic health coefficient; the θ 静 is the static health factor; H is the first safety factor. If the value of the first safety factor is less than 0, set H = 0.

[0106] In this way, the dynamic health coefficient of the water pump equipment is determined according to the coefficient change rate of different components of the water pump equipment, comprehensively considering the factors that affect the health status of the water pump equipment and ensuring the accuracy of the first safety factor.

[0112] determining a sixth value based on a difference between the fifth value and a temperature reference value;

[0113] A heat transfer coefficient of the air cooler is determined based on a ratio of the sixth value to the temperature reference value.

[0114] For example, one way to determine the heat transfer coefficient of the air cooler is: Among them, the T 进 is the first temperature, which is the temperature of the water inlet to the air cooler; 出 is the second temperature, which is the temperature of the water outlet from the air cooler; 参 is the temperature reference value; and R is the heat transfer coefficient of the air cooler.

[0161] Step S360: The terminal calculates a penalty factor δ=δ / γ;

[0170] In one embodiment, the first weight Q corresponding to different water pump devices is determined according to the influence ratio of different water pump devices on the target system; the second weight Q corresponding to the air cooler group is determined according to the influence ratio of the air cooler group on the target system. K ; Among them, the first weight Q of the 1st to nth water pump equipment and the second weight Q of the air cooler group K The sum of is 1.

[0171] Exemplarily, if the target system includes: a first water pump device, the first weight Q1=1.

[0172] For example, if the target system includes: a first water pump device, a second water pump device, a third water pump device and an air cooler group, the sum of the weights of the first water pump device, the second water pump device, the third water pump device and the air cooler group is 1. Since the first water pump device and the second water pump device have a higher impact on the target system, the first weight of the first water pump device can be set to: Q1 = 0.3, and the first weight of the second water pump device can be set to: Q2 = 0.3; the air cooler group has the second largest impact on the target system, so the second weight of the air cooler group can be set to Q K =0.25; and the influence of the third water pump device on the target system is relatively low, so the first weight of the third water pump device can be set to: Q3=0.15.

[0173] In one embodiment, determining the comprehensive safety factor based on the minimum value of the at least one weighted first safety factor and the weighted second safety factor includes:

[0174] The comprehensive safety factor is determined based on the minimum value of the weighted first safety factors of the 1st to nth water pump devices and the weighted second safety factors of the air cooler group; wherein n is greater than 0.

[0175] For example, one way to determine the comprehensive safety factor is: Among them, the is the weighted first safety factor of the nth water pump equipment; the R 总 ×Q K is the weighted second safety factor of the air cooler group; and S is the comprehensive safety factor.

[0176] In this way, by assigning weights to at least one water pump device and air cooler group, the comprehensive safety factor can be made more accurate and reliable. The minimum value of at least one weighted first safety factor and a weighted second safety factor is determined as the comprehensive safety factor of the target system, ensuring that the safety status information of the target system determined according to the comprehensive safety factor is true and valid, which facilitates the judgment of the health status of the target system.

[0177] In some embodiments, the method further comprises at least one of the following:

[0178] outputting the security status information;

[0179] Outputting prompt information corresponding to the security status information;

[0180] If the comprehensive safety factor is less than or equal to a first predetermined value, early warning information corresponding to the safety status information is output.

[0181] In some embodiments, the outputting of the security status information includes at least one of the following:

[0182] Outputting security status information on a display screen of the target system or terminal;

[0183] Outputting security status information based on the voice of the target system or terminal;

[0184] The security status information is sent to a third-party platform, where the security status information is displayed on the third-party platform.

[0185] Exemplarily, outputting the security status information may be outputting the security status information in text form on the terminal's display screen; or the terminal may output the security status information in the form of a voice signal; or the terminal may generate a security report and send it to the user's mailbox in the form of an email, wherein the security report contains the security status information.

[0186] In some embodiments, the outputting of prompt information corresponding to the security status information includes at least one of the following:

[0187] Outputting prompt information corresponding to the security status information on the display screen of the target system or terminal;

[0188] Outputting prompt information corresponding to the security status information based on the voice of the voice device of the target system or terminal;

[0189] Send the prompt information corresponding to the security status information to the third-party platform, and the prompt information is used for the third-party platform to display

[0190] In some embodiments, the prompt information includes but is not limited to at least one of the following: text information, voice information, picture information, and color information. The prompt information includes warning information.

[0191] In some embodiments, the comprehensive safety factor can be divided into at least one comprehensive safety factor interval, and different comprehensive safety factor intervals are bounded by different predetermined values, and different comprehensive safety factor intervals correspond to different safety status information.

[0192] For example, if the comprehensive safety factor ranges from 0 to 1, it is divided into three comprehensive safety factor intervals. The first predetermined value can be any number between 0.3 and 0.4, for example, 0.3; the second predetermined value can be any number between 0.6 and 0.8, for example, 0.7. Therefore, 0-0.3 is the first comprehensive safety factor interval, 0.3-0.7 is the second comprehensive safety factor interval, and 0.7-1 is the third comprehensive safety factor interval.

[0193] For example, if the comprehensive safety factor ranges from 0 to 100, it is divided into four comprehensive safety factor intervals. The first predetermined value may be 25, the second predetermined value may be 50, and the third predetermined value may be 75. Thus, 0-25 is the first comprehensive safety factor interval, 25-50 is the second comprehensive safety factor interval, 50-75 is the third comprehensive safety factor interval, and 75-100 is the fourth comprehensive safety factor interval.

[0194] In some embodiments, different prompt messages correspond to different color information. For example, if the first predetermined value is 0.4 and the second predetermined value is 0.7, then the range of 0 to 0.4 represents the first comprehensive safety factor, and the corresponding safety status information indicates that the target system is in an unhealthy state, experiencing a fault and requiring troubleshooting. The range of 0.4 to 0.7 represents the second comprehensive safety factor, indicating that the target system is in a subhealthy state, capable of operation but requiring debugging and maintenance. The range of 0.7 to 1 represents the third comprehensive safety factor, indicating that the target system is in a healthy state, operating normally. If the terminal determines that the comprehensive safety factor is 0.3, which is less than the first predetermined value and falls within the first comprehensive safety factor range, the terminal's display screen will output the warning information in red, and the terminal's buzzer will emit a voice warning signal. If the terminal determines that the comprehensive safety factor is 0.5, which is greater than the first predetermined value and less than the second predetermined value and falls within the second comprehensive safety factor range, the terminal's display screen will output the prompt information in yellow. If the terminal determines that the comprehensive safety factor is 0.9, which is greater than the second predetermined value and falls within the third comprehensive safety factor range, the terminal's display screen will output the prompt information in green.

[0195] In this way, by comparing the comprehensive safety factor with a predetermined value, the safety status information represented by the comprehensive safety factor of the target system can be determined, and prompt information corresponding to the safety status can be output. The prompt information can accurately inform the current health status of the target system, allowing users to take timely countermeasures based on the prompt information. Moreover, if the safety status information corresponding to the comprehensive safety factor indicates that the target system is operating abnormally, timely feedback and warning information can be output through various methods. This can reduce property losses caused by damaged equipment in the target system and the occurrence of safety accidents, providing protection for the healthy operation of the target system and the safety of users.

[0197] In one embodiment, Figure 5 As shown, an embodiment of the present application provides a safety evaluation method, the method comprising:

[0198] Step S510: The sensor of the target system obtains the operating parameters of the target system related equipment and sends them to the terminal;

[0199] Here, the terminal may be provided in the target system and establish a communication connection with the sensor of the target system; or the terminal may be outside the target system and establish a communication connection with the sensor of the target system.

[0207] The terminal is based on the dynamic health coefficient θ 动 and static health coefficient θ 静 , determine the first safety factor H: H = 1-(θ 静 +θ 动 ).

[0208] Step S530: The terminal calculates a second safety factor of the air cooler group based on the inlet and outlet water temperatures and flow rates of the air cooler;

[0209] The terminal is based on the inlet water temperature T of each air cooler 进and the temperature of the air cooler outlet water T 出 The difference between the temperature reference value T 参 , determine the heat transfer coefficient R of each air cooler:

[0210] If the terminal determines that the air cooler group includes three air coolers, the terminal obtains the second safety factor R of the air cooler group based on the heat transfer coefficients of the three air coolers included in the air cooler group. 总 :R 总 =R1+R2+R3.

[0211] Step S540: The terminal combines the first safety factor of the water pump equipment and the second safety factor of the air cooler group, performs a weighted comprehensive calculation, and performs a safety evaluation of the entire target system based on an autonomous algorithm;

[0212] If the terminal determines that the target system includes two water pump devices, the terminal determines a weighted first safety factor y for each water pump device based on the first safety factor H, the safety factor reference value C of the water pump device, and the first weight Q of the water pump device:

[0213] The terminal is based on the second safety factor R 总 and the second weight Q of the air cooler group K Determine the second safety factor z of the air cooler group: z = R 总 ×Q K .

[0214] The terminal determines the comprehensive safety factor S based on the minimum value of the two weighted first safety factors y and the weighted second safety factor z:

[0215] Step S550: The terminal's display screen displays the target system's security status, with different statuses displayed using different graphics.

[0216] If the terminal determines that the comprehensive safety factor indicates that the target system is in a healthy state of normal operation, the terminal's display screen displays a green "√" picture; if the terminal determines that the comprehensive safety factor indicates that the target system is in a sub-healthy state that can be operated but requires debugging and maintenance, the terminal's display screen displays a yellow "!" picture; if the terminal determines that the comprehensive safety factor indicates that the target system is in an unhealthy state that has a fault and cannot operate and needs to be troubleshooted, the terminal's display screen displays a red "×" picture.
