[0002] Switchgear is an electrical equipment that assembles busbars, circuit breakers, mutual inductors, transformers, secondary current, secondary voltage and measurement and control devices in grounded compartments separated by metal partitions. It is mainly used for the normal operation of power generation, transmission, distribution and power conversion in power systems. When the outside is in rainy or cold weather, due to some reasons, the temperature change inside the switchgear meets the heat generated by the operation of the electrical components inside the switchgear and condenses into water droplets, which adhere to the wall of the switchgear or the surface of the electrical components, causing the insulation performance of the electrical components to decrease due to the accumulation of water droplets, which in turn causes short circuit, open circuit and other faults of the electrical components, seriously affecting the normal operation of the power system.

[0003] At present, in response to the above problems, a manual monitoring control method is used to control the internal environment of the switch cabinet, that is, by measuring the temperature parameters and humidity parameters in the switch cabinet on site, and judging whether they exceed the prescribed range, if so, starting the adjustment equipment to ensure that the environmental parameters return to the normal range.

[0004] However, when the switch cabinet is in a low-temperature environment, not only is the speed of manual monitoring unable to match the speed of condensation in the switch cabinet, but it is also affected by human factors, such as delayed human response or human misjudgment, which leads to the inability to timely and accurately determine the time when the temperature and humidity data in the switch cabinet are abnormal, increasing the risk of component failure in the switch cabinet. Summary of the invention

[0018] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0019] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0020] When the switch cabinet is in a low temperature environment, in order to effectively prevent the occurrence of condensation, a manual monitoring method is generally used. This method involves directly measuring the temperature and humidity parameters inside the switch cabinet on site, and evaluating whether these parameters are out of bounds according to preset standards. Once it is found that the parameters are beyond the normal range, the corresponding adjustment device is immediately activated to quickly restore the environmental parameters to a safe range. However, the inherent limitation of this monitoring method is that the speed of manual response is difficult to match the rapidity of condensation formation inside the switch cabinet, which often leads to monitoring actions lagging behind the actual occurrence of condensation and inaccurate judgments. In view of this, the inventor of this case aims to transform the existing manual patrol monitoring mode into a system automation monitoring solution. Specifically, the solution collects the environmental parameters in the switch cabinet autonomously through the system, and accurately tracks its temperature changes. Based on the temperature change information obtained, it can intelligently judge and timely adjust the temperature and humidity data in the switch cabinet. In this process, manual intervention is completely abandoned, and the whole process from data collection, environmental assessment to regulation and control is realized. Automation and intelligence. Compared with traditional manual monitoring methods, this monitoring system can automatically and accurately identify ambient temperature data and its changing trends, and implement real-time regulation of the temperature and humidity in the switch cabinet based on these dynamic information. This not only significantly improves the accuracy of monitoring, but also ensures that abnormal changes in environmental parameters in the switch cabinet can be discovered and responded to in the first place, thereby achieving effective prevention and control of condensation.

[0021] To this end, the inventor of the present application proposes a monitoring method for a switch cabinet, which can be automatically executed according to predetermined steps, that is, after receiving a humidity adjustment instruction, multiple sets of ambient temperature data and infrared images in the switch cabinet are collected, and the temperature change trend in the switch cabinet is determined. Combined with the temperature change trend in the switch cabinet, it is determined whether there is a safety risk to the components in the target switch cabinet, and after determining that there is a risk, the ambient temperature and humidity in the switch cabinet can be adjusted by starting the temperature and humidity adjustment device. A monitoring method for a switch cabinet in an embodiment of the present invention, the specific steps are as follows: Figure 1 As shown, including:

[0022] 101. Obtain humidity adjustment instructions.

[0023] When the switch cabinet is placed in a high temperature environment, the high external ambient temperature is often accompanied by relatively low air humidity, and such environmental conditions are not conducive to the occurrence of condensation. However, when the switch cabinet is in a low temperature environment, the external air humidity is high or the internal temperature of the switch cabinet is further reduced for some reason, which will cause condensation. To avoid this situation, it is necessary to set a humidity adjustment instruction, which is designed to intelligently adjust the internal humidity data of the switch cabinet according to the temperature changes in the environment where the switch cabinet is located, so as to ensure that the formation of condensation can be effectively prevented in a low temperature environment, which can significantly improve the operating stability and safety of the equipment and avoid electrical failures or short circuits caused by condensation.

[0024] The humidity adjustment command obtained is used to adjust the humidity data in the switch cabinet when the switch cabinet is in a low temperature environment. The monitoring personnel can turn on the adjustment command switch when they independently judge the need to prevent condensation in the switch cabinet based on the external environment; or they can monitor the current environment of the switch cabinet based on an infrared detection system or a temperature sensor. If the environment in which the switch cabinet is located is a low temperature environment, the system will automatically turn on the adjustment command switch after receiving the instruction that the current environment is a low temperature environment. The conditions that meet the low temperature environment can be winter, rainy and snowy weather, or specific environmental conditions when the temperature is lower than a certain temperature value, and no excessive restrictions are made here.

[0025] 102. Continuously collect multiple sets of ambient temperature data and infrared images in the switch cabinet within a preset period according to the humidity adjustment instruction.

[0026] After receiving the humidity adjustment instruction in step 101, the system will obtain multiple sets of data within a preset period, and the multiple sets of data include ambient temperature data and infrared images, wherein the infrared image contains the temperature of the components in the target switch cabinet to be monitored, and the multiple sets of ambient temperature data and infrared images refer to the ambient temperature data and infrared image data at multiple times within the preset period.

[0027] When acquiring multiple sets of ambient temperature data and infrared images, the temperature and humidity sensor and the infrared camera may be turned on only after receiving the humidity adjustment instruction, or the temperature and humidity sensor and the infrared camera may be turned on all the time to acquire the ambient temperature data and infrared images in real time. Regardless of the method used to acquire the data required for monitoring, the acquired ambient temperature data and infrared images are stored in a preset data table. In addition, the ambient data and infrared images in the preset data table may also be stored in association with the specific temperature of the external environment in which the switch cabinet is currently located, so as to record the correspondence between the external environment in which the switch cabinet is located and the temperature data in the switch cabinet, and optimize the monitoring system of the switch cabinet according to the recorded correspondence. It is worth noting that the above ambient temperature data is the data measured by at least one temperature sensor. If there are multiple temperature and humidity sensors in the switch cabinet, the ambient temperature data is the average value of the measured data. Such a processing method can more accurately reflect the temperature conditions in the switch cabinet, and avoid inaccurate judgment of the ambient temperature due to the number of temperature and humidity sensors.

[0028] In this step, since components with different temperatures emit infrared radiation of different intensities, usually, components with higher temperatures will appear as brighter colors in infrared images, such as red, orange or yellow, while components with lower temperatures may appear as darker colors, such as blue, purple or black. Infrared cameras can capture the infrared radiation emitted by components and convert it into a visual image. In the infrared image, the color or brightness of each pixel represents the temperature information of the corresponding position. Therefore, infrared imaging technology can be used to establish the relationship between the temperature and radiation energy of components to determine the temperature of components in the target switch cabinet to be monitored. The preset period can be a few minutes, a few hours, or a few days, and there is no excessive limitation on this. In this step, the infrared image can be one or more images. If there are multiple infrared images, the temperature of the component is the average temperature.

[0029] 103. Determine a temperature change trend in the switch cabinet according to the multiple sets of ambient temperature data and infrared images.

[0030] After multiple sets of ambient temperature data and infrared images are acquired in step 102, the multiple sets of ambient temperature data and infrared images can be analyzed according to a time series to determine the temperature change trend in the switch cabinet. The specific method for determining the temperature change trend in the switch cabinet can be to separately determine the change trend of the ambient temperature number and the temperature change trend of the components in the target switch cabinet, and then determine the temperature change trend in the switch cabinet based on the change trend of the ambient temperature number and the temperature change trend of the components in the target switch cabinet; or it can be to first determine the temperature difference at any time within the preset period, and use the change trend of the temperature difference as the temperature change trend in the switch cabinet, wherein the temperature change trend refers to the direction of temperature change in the switch cabinet over a period of time.

[0031] 104. Use the temperature change trend to predict whether there are safety risks to components in the target switch cabinet.

[0032] After determining the temperature change trend in step 103, it can be further determined whether the components in the target switch cabinet will have safety risks due to condensation in the switch cabinet. After obtaining the temperature change trend, the method for predicting whether the components have safety risks can be based on the rate of change of the temperature difference at the last moment in the preset period, judging whether the temperature change value in the switch cabinet within the first preset time predicted by the change rate is greater than or equal to the first safety threshold, if so, there is a risk, wherein the first safety threshold is a pre-set value used to judge whether the temperature change in the switch cabinet is within a safe range. The method for predicting whether the components have safety risks can also be to determine the environmental data value at a preset second time according to the environmental data change trend, determine the component temperature value at the preset second time according to the component temperature change trend, and judge whether the component has safety risks according to the environmental data value and the component temperature value.

[0033] In this step, the target switch cabinet components refer to the busbar, circuit breaker, mutual inductor, transformer, secondary current, secondary voltage and any components in the measurement and control device in the switch cabinet. Safety risk refers to the situation where the components in the target switch cabinet are short-circuited or short-circuited due to condensation, thereby affecting the normal use of the components in the switch cabinet.

[0034] 105. If present, start the temperature and humidity control equipment.

[0035] After determining in step 104 that there is a safety risk in the components in the target switch cabinet, the system uses the adjustment instruction to start the temperature and humidity adjustment device, where the temperature and humidity adjustment device can be an air conditioner, a dehumidifier, or a heater. For example, when the humidity in the switch cabinet is high and the temperature is low, the dehumidifier can be started to reduce the humidity; if the temperature is too low, the heater can be started to appropriately increase the temperature, or the air conditioner can be started to maintain suitable environmental conditions in the switch cabinet through cooling or heating and dehumidification functions. These temperature and humidity adjustment devices can work alone or in combination according to actual conditions to achieve the best adjustment effect and ensure the safe and stable operation of the components in the target switch cabinet.

[0036] After determining that there is a safety risk in the components in the target switch cabinet, the system will start the temperature and humidity control equipment to adjust the humidity data and / or temperature data in the current switch cabinet. When adjusting the temperature data and / or humidity data in the switch cabinet, the temperature data and / or humidity data in the switch cabinet will be continuously monitored to determine whether the adjustment of the humidity data in the switch cabinet can avoid the components from being in safety risks.

[0037] Based on the above Figure 1 It can be seen from the implementation method that the present application provides a monitoring method for a switch cabinet. The scheme determines that the current external environment of the switch cabinet is a low-temperature environment by obtaining a humidity adjustment instruction. At this time, the humidity data in the switch cabinet needs to be adjusted. After receiving the humidity adjustment instruction, the ambient temperature data and infrared image in the switch cabinet are automatically collected, and the temperature change trend in the switch cabinet is determined based on this data. Since the ambient temperature data and infrared image in the switch cabinet are automatically collected after the humidity adjustment instruction is triggered, compared with manual data collection, the errors caused by the manual measurement process can be avoided, and the accuracy of the ambient temperature data and infrared images is guaranteed, so that the temperature change trend in the switch cabinet determined based on the data is more accurate. Since the temperature change trend in the switch cabinet is determined based on accurate data, it is possible to timely and accurately predict whether there is a safety risk in the components in the target switch cabinet based on the temperature change trend in the switch cabinet. When there is a risk in the components in the switch cabinet, the temperature and humidity adjustment device is started to adjust the temperature and humidity in the switch cabinet to prevent the occurrence of condensation. It can be seen that by automatically collecting data, determining the temperature change trend in the switch cabinet, and judging whether there are safety risks in components, the temperature and humidity adjustment equipment is started to avoid the untimely and erroneous manual monitoring. It can automatically, timely and accurately judge the abnormal moments of temperature and humidity data in the switch cabinet in a low temperature environment, prevent condensation, and ensure the stable operation of the power system in the switch cabinet.

[0038] Furthermore, according to the above Figure 1 In the embodiment of the present invention shown in FIG. 1 , after obtaining multiple sets of ambient temperature data and infrared images, how to determine the temperature change trend in the switch cabinet and how to determine whether there is a safety risk in the components in the target switch cabinet are described in more detail. The specific steps are as follows Figure 2 As shown, including:

[0039] 201. Acquire multiple groups of ambient temperature data and infrared images in the switch cabinet according to the humidity adjustment instruction.

[0040] After the system obtains the humidity adjustment instruction, the system will continuously collect multiple sets of ambient temperature data and infrared images in the switch cabinet within a preset period according to the humidity adjustment instruction, wherein the multiple sets of ambient temperature data and infrared images are multiple ambient temperature data and infrared images at the same time. Among them, the multiple sets of ambient temperature data and infrared images can be stored in a preset data table, which includes the acquisition time, ambient temperature data and temperature data of components in the switch cabinet. This storage method has many advantages: on the one hand, the acquisition time, ambient temperature data and temperature data of components in the switch cabinet are clearly recorded, so that the system can accurately locate the data in a specific time period when analyzing the data, and ensure that the system obtains accurate data in the switch cabinet in the same time period. In this way, whether it is temperature change trend analysis or judgment of whether there is a safety risk, it can be based on the accurate time correspondence relationship to avoid erroneous judgments caused by data time mismatch. On the other hand, by storing multiple sets of ambient temperature data and infrared images in the preset data table in chronological order, it is convenient for the system to compare and filter data. In the same time period, the system can accurately determine the temperature abnormality point or the abnormal temperature of the component, and take corresponding measures in time to ensure the safe operation of the switch cabinet.

[0041] In the above steps, the switch of the humidity adjustment command can be a humidity adjustment command switch automatically generated by the system when the temperature sensor installed outside the switch cabinet recognizes that the temperature environment of the switch cabinet is a low temperature environment, or it can be a humidity adjustment command switch automatically turned on by the monitoring personnel based on the current environment. The humidity adjustment command is used to adjust the humidity data inside the switch cabinet when the switch cabinet is in a low temperature environment.

[0042] 202. Determine a temperature change trend in the switch cabinet according to the multiple sets of ambient temperature data and infrared images.

[0043] After obtaining multiple sets of ambient temperature data and infrared images in step 201, there are two methods for determining the temperature change trend in the switch cabinet in this embodiment, which are as follows:

[0044] Method 1: Obtain the temperature difference between the temperature data of the components in the target switch cabinet and the ambient temperature data according to the time series method; if the maximum value of the temperature difference is less than or equal to the first safety threshold, determine the change trend of the temperature difference as the temperature change trend in the switch cabinet.

[0045] The specific implementation of the above method is: first, determine whether the temperature data and ambient temperature data of the components in the target switch cabinet within the preset period are complete and valid, wherein the data integrity is determined by whether the temperature data and ambient temperature data of the components in the target switch cabinet exist at the same time. If they exist at the same time, it is determined that the temperature data and ambient temperature data of the components in the target switch cabinet at the same time are complete. Then further determine whether the temperature data and ambient temperature data of the components in the target switch cabinet are valid. The specific method for determining whether the temperature data and ambient temperature data of the components in the target switch cabinet are valid is: determine by the temperature data corresponding to a period of time before and after the moment. If the temperature data corresponding to the moment is compared with the temperature data corresponding to a period of time before and after the moment, there is a large deviation, then the temperature data at the moment is determined to be invalid, and all data at the moment are deleted, wherein the large deviation is based on the experience of technical personnel in this field. Secondly, when it is determined that the temperature data is complete and valid, the temperature difference at the same moment is calculated, and the temperature difference is used to indicate the temperature change value in the switch cabinet. After determining multiple temperature differences within a preset period, the maximum temperature difference among the temperature differences is determined based on the multiple temperature differences, and then it is determined whether the maximum temperature difference is less than or equal to the first safety threshold. The purpose is to determine whether the temperature change in the switch cabinet is within the safe range of temperature change. If the maximum temperature difference is greater than the first safety threshold, it means that the temperature change in the switch cabinet exceeds the safe range of temperature change, which will cause safety risks to the components in the switch cabinet. At this time, the system will issue an alarm message to remind the monitoring personnel that the switch cabinet components are at safety risk and need to be handled urgently. If the maximum value of the temperature difference is less than or equal to the first safety threshold, it means that the temperature change in the switch cabinet is within the safe range of temperature change. At this time, all temperature differences are sorted in chronological order to determine the change trend of the temperature difference, and then the change trend of the temperature difference is determined as the temperature change trend in the switch cabinet within the preset period.

[0046] In the above method, the first safety threshold is a pre-set value, which is used to determine whether the temperature change in the switch cabinet is within a safe range. The setting of this threshold takes into account factors such as the working characteristics, environmental requirements and safety standards of the components in the switch cabinet. For example, for some components that are more sensitive to temperature changes, the first safety threshold may be set relatively small to ensure that potential safety risks can be discovered in time when the temperature difference is small. It is worth noting that the first safety threshold can be determined through experiments, experience summary or reference to relevant standards. In practical applications, the first safety threshold can also be adjusted and optimized according to different switch cabinet types, usage environments and component configurations. The alarm information can be sent to the monitoring personnel through a specific device. The specific alarm form can be a vibration alarm, a sound alarm, or a light alarm. The alarm form is not limited here.

[0047] The above method is now described with examples, such as the ambient temperature and component temperature data for a period of time in Table 1, and the first safety threshold is 1°C.

[0048] Table 1

[0049] Time(S) T1 T2 T3 T4 Ambient temperature (℃) 24.9 25.2 25.6 26.1 Component temperature (℃) 24.7 24.9 25.2 25.6

[0050] According to the data in Table 1, the temperature difference at T1, T2, T3, and T4 can be determined to be 0.2°C, 0.3°C, 0.4°C, and 0.5°C, respectively. At this time, since the first safety threshold is 1°C, the maximum temperature difference is 0.5°C, and 0.5°C is less than 1°C, 0.2°C, 0.3°C, 0.4°C, and 0.5°C are analyzed in sequence according to T1, T2, T3, and T4. During the analysis, auxiliary means such as line graphs, bar graphs, and trend models can be used to analyze the temperature difference, and then determine that the temperature difference is continuously increasing during the time period from T1 to T4. At this time, the temperature change trend in the switch cabinet is determined to be continuously increasing. It should be noted that in this example, only four time points are given to facilitate the explanation of the specific implementation of the above method. In actual applications, the number of groups of ambient temperature data and temperature data of components in the target switch cabinet is obtained according to actual conditions.

[0051] It can be seen that calculating the temperature difference through the time series method can effectively reflect the temperature changes of the components in the switch cabinet relative to the environment. It can not only capture the instantaneous temperature fluctuations, but also reveal the long-term trend of temperature changes over time, providing a reliable data basis for subsequent safety risk prediction. Secondly, comparing the maximum value of the temperature difference with the first safety threshold provides a clear standard for judging the temperature state in the switch cabinet. Finally, the changing trend of the temperature difference is determined as the temperature change trend in the switch cabinet, providing the system with intuitive temperature change information. Through the analysis of this trend, we can better understand the temperature dynamics in the switch cabinet and take corresponding preventive measures in advance, such as adjusting the parameters of the temperature and humidity control equipment, to ensure the normal operation of the switch cabinet.

[0052] Method 2: Analyze multiple sets of ambient temperature data and infrared images according to the time series method to obtain the temperature change trend of components and the change trend of the ambient temperature; determine the temperature change trend in the switch cabinet according to the temperature change trend of components and the change trend of the ambient temperature.

[0053] The specific implementation of the above method 2 is: first, determine the validity of environmental data and infrared images. In this step, it is necessary to check whether there are environmental temperature data and infrared images at the same time within the preset period, which ensures the synchronization and integrity of the data. After confirming that both exist at the same time, further detect abnormal values ​​on the data. Abnormal values ​​may be caused by factors such as sensor failure, data transmission error or external interference, which will interfere with the accuracy of the data. Therefore, they must be identified and processed. If no abnormal values ​​are found after detection, the data at this moment is considered to be valid and can be used for subsequent analysis. Secondly, determine the change trend of the ambient temperature based on multiple sets of valid ambient temperature data, which can be achieved by applying time series analysis technology, such as using moving average method, exponential smoothing method or autoregressive model. Since infrared images can reflect the temperature distribution on the surface of components, by extracting the temperature information in the image, the temperature values ​​of components at different times can be obtained. Therefore, the temperature change trend of components in the target switch cabinet can be determined based on multiple sets of valid infrared images. According to the change trend of the ambient temperature and the change trend of the temperature of the components, the temperature change trend in the switch cabinet can be determined.

[0054] Taking the data in Table 1 as an example, the above method 2 is described in detail:

[0055] According to the data in Table 1, the environmental data is 24.9℃, 25.2℃, 25.6℃, and 26.1℃, and the temperature difference between adjacent moments can be calculated as 0.3℃, 0.4℃, and 0.5℃. Based on the temperature difference of the environmental data, it can be determined that the change trend of the environmental data is continuously increasing; the temperature data of the components is 24.7℃, 24.9℃, 25.2℃, and 25.6℃, and the temperature difference between adjacent moments can be calculated as 0.2℃, 0.3℃, and 0.4℃. Based on the temperature difference of the components at adjacent moments, it can be determined that the temperature change trend of the components is continuously increasing. Based on the change trend of the environmental data and the temperature change trend of the components, it is determined that the change trend of the ambient temperature in the switch cabinet is continuously increasing. It is worth noting that the changing trend of environmental data, the changing trend of temperature of components and the changing trend of ambient temperature in the switch cabinet can be determined according to the trend prediction model. The trend model is trained and tested based on historical data and can be directly applied. During use, the type of changing trend to be determined can be selected. After selecting the type of changing trend (such as the changing trend of environmental data, the changing trend of temperature of components and the changing trend of ambient temperature in the switch cabinet), the changing trend type can be obtained by inputting the corresponding data.

[0056] In summary, method 2 in this embodiment improves data accuracy by first verifying the synchronization and integrity of ambient temperature data and infrared images, eliminating abnormal values, and then applying time series analysis technology to determine the changing trends of ambient temperature and component temperature; finally, judging the temperature changing trend in the switch cabinet through the above two aspects, it can avoid the situation where the temperature changing trend in the switch cabinet is inaccurately judged in a single case, and improve the accuracy of determining the temperature changing trend in the switch cabinet.

[0057] In order to ensure the accuracy of the environmental data in the above methods 1 and 2, this embodiment also sets the position of the temperature and humidity sensor for collecting environmental data, wherein the setting of the temperature and humidity sensor position can be before obtaining the humidity adjustment instruction, and the specific setting method is as follows:

[0058] First, the operating time of the components in the switch cabinet is determined according to the operating schedule of the components in the switch cabinet, and the components in the switch cabinet whose operating time is greater than the third preset time are judged, and the area where the components are located is determined as the first area. The first area is used to indicate the area where the operating time of the components in the switch cabinet is greater than the third preset time. These areas usually have high component density and high heat generation, and are the focus of temperature and humidity monitoring. The other areas in the switch cabinet except the first area are determined as the second area. The second area is used to indicate the area where the operating time in the switch cabinet is less than the third preset time. These areas have relatively few components and low heat generation. Secondly, after determining the first area and the second area, regardless of whether the number of temperature and humidity sensors is fixed, the number of temperature and humidity sensors can be allocated according to multiple parameters of the first area and the second area, where the multiple parameters can be actual power (here it can be understood as the total power consumption or heat generation of components), heat dissipation conditions, space size, component density in the area, and the sensitivity of components to temperature and humidity sensors. The specific allocation method can be to allocate the number of temperature and humidity sensors according to the actual power ratio of each area, or to allocate temperature and humidity sensors according to the proportion of component density in each area, or to allocate more temperature and humidity sensors to areas with poor heat dissipation conditions. Because areas with poor heat dissipation are more likely to have temperature and humidity problems, more intensive monitoring is required. There is no limitation on the parameters of the first area and the second area here. It can be one parameter or a combination of two parameters.

[0059] After determining the number of temperature and humidity sensors in the first area and the second area, determine the location of the temperature and humidity sensors according to the regional characteristics. Specifically, within the third preset time, the area where the components in the switch cabinet whose operating time is greater than the first preset value are located forms the first area, and the areas where the components in the first area are located are interconnected to form an integral area; the area where the components in the switch cabinet whose operating time is less than or equal to the first preset value are located forms the second area, and the areas where the components in the second area are located are interconnected to form an integral area. The first area and the second area can be divided into regions according to the number of temperature and humidity sensors, and the specific method of regional division is to evenly divide the areas of the first area and the second area according to the number of temperature and humidity sensors in the first area and the second area, obtain multiple areas, and calculate the center point positions of the multiple areas, and determine the center positions of the multiple areas as the positions of the temperature and humidity sensors in the area. If within the third preset time, the areas where the components in the switch cabinet whose operating time is greater than the first preset value are located constitute the first area, and the areas where the components in the first area are not connected to each other; the areas where the components in the switch cabinet whose operating time is less than or equal to the first preset value are located constitute the second area, and the areas where the components in the second area are not connected to each other, then the areas of the independent areas constituting the first area and the second area are sorted according to the numerical values, and the independent areas where the number of temperature and humidity sensors are set are determined according to the number of sensors in the area, and the center points of the determined independent areas are used as the positions of the temperature and humidity sensors. Within the third preset time, the areas where the components in the switch cabinet whose operating time is greater than the first preset value are located constitute the first area, and at least one area where the components are located is not connected to other parts of the first area; the areas where the components in the switch cabinet whose operating time is less than or equal to the first preset value are located constitute the second area, and at least one area where the components are located is not connected to other parts of the first area, the areas of the interconnected parts in the first area and the second area can be evenly divided according to fixed proportions, and the center points of the divided areas and at least one area where the components are located are used as the positions of the temperature and humidity sensors.

[0060] It can be seen that by clarifying the key areas and general areas for temperature and humidity monitoring, the monitoring can be more targeted. Secondly, allocating the number of temperature and humidity sensors based on multiple parameters can make the sensors more reasonably laid out. For situations with different regional characteristics, the center position is determined as the location of the temperature and humidity sensor, ensuring the scientific and rational layout of the sensors, thereby improving the accuracy of environmental data and providing strong guarantees for timely detection of temperature and humidity problems and taking corresponding measures.

[0061] 203. Determine whether there is a safety risk for components in the switch cabinet according to a temperature change trend in the switch cabinet.

[0062] After determining the temperature change trend in the switch cabinet in step 202, there are two ways to determine whether there are safety risks in the components in the switch cabinet in this embodiment, as follows:

[0063] Method 1: Predict the temperature change value in the switch cabinet within the first preset time based on the change rate of the temperature difference at the last moment within the preset period; determine whether the temperature change value in the switch cabinet is greater than or equal to the first safety threshold; if so, determine that there is a safety risk in the components in the target switch cabinet.

[0064] Taking the data in Table 1 above as an example, if the time interval between T1, T2, T3, and T4 is 1 second, the first preset time is 50 seconds, and the first safety threshold is 4°C, the above method is illustrated as follows:

[0065] According to the data in Table 1, the environmental data are 24.9°C, 25.2°C, 25.6°C, and 26.1°C, and the temperature data of the components are 24.7°C, 24.9°C, 25.2°C, and 25.6°C. At this time, the difference between the environmental data and the temperature data of the components at T1, T2, T3, and T4 is 0.2°C, 0.3°C, 0.4°C, and 0.5°C. The temperature change rate at T4 can be calculated to be (0.5-0.4) / (T4-T3), which is 0.1°C / s. The temperature change value in the switch cabinet within the first preset time is 5°C. At this time, the first safety threshold is 4°C. Since 5°C is greater than 4°C, it is determined that there is a safety risk in the components in the target switch cabinet.

[0066] Method 2: Based on the temperature change trend of the components, predict the temperature value of the components at the second preset time; based on the ambient temperature change trend, predict the ambient temperature value at the second preset time; if the difference between the temperature value of the component and the ambient temperature value is not within the second safety threshold, determine that there is a safety risk in the components in the target switch cabinet, where the second safety threshold is the numerical range in which there is no safety risk in the components in the target switch cabinet.

[0067] Taking the data in Table 1 above as an example, the time intervals between T1, T2, T3, and T4 are 0.1 seconds, the second preset time is 1.5 seconds, and the second safety threshold is [0°C, 2.5°C]. The above method is described by way of example, as follows:

[0068] According to the data in Table 1, the environmental data are 24.9°C, 25.2°C, 25.6°C, and 26.1°C. It can be calculated that the temperature change rate of the environmental data at time T4 is 5°C / s. At this time, it can be predicted that the environmental data at the second preset time is 31.1°C; the temperature data of the components are 24.7°C, 24.9°C, 25.2°C, and 25.6°C. It can be calculated that the temperature change rate of the components at time T4 is 4°C / s. At this time, it can be predicted that the temperature data of the components at the second preset time is 29.6°C. It can be seen that (31.1-29.6) is within the second safety threshold, and there is no safety risk to the components in the switch cabinet at this time.

[0069] 204. If yes, determine the safety risk type of the components in the switch cabinet and determine the adjustment parameters of the temperature and humidity control equipment according to the risk type.

[0070] After determining in step 203 that there is a safety risk in the components in the switch cabinet, there are two methods for determining the type of safety risk of the components in the switch cabinet, as follows:

[0071] Method 1: Determine the time to reach the safety threshold based on the rate of change of the temperature difference and the first safety threshold, where the time to reach the safety threshold is the time required for the temperature change value in the switch cabinet to reach the first safety threshold from the last moment of the preset cycle; determine the safety risk type of the components in the target switch cabinet based on the time to reach the safety threshold; the shorter the time to reach the safety threshold, the higher the safety risk type of the components in the switch cabinet, and the safety risk types are divided into Class I, Class II, Class III...N, where Class I has the lowest risk factor and Class N has the highest risk factor. After determining the safety risk type, determine the adjustment parameters of the temperature and humidity adjustment equipment in combination with the preset control strategy table, where the adjustment parameters include the operating power, operating time, temperature adjustment range, humidity adjustment range, etc. of the temperature and humidity adjustment equipment.

[0072] In this method, the preset control strategy table not only stores the adjustment data corresponding to different safety risk types, but also stores the range of the time to reach the safety threshold corresponding to the safety risk type. The first safety threshold is the maximum value of the temperature change in the switch cabinet within the preset period. The time to reach the safety threshold refers to the time required from the last moment of the preset period until the temperature change value in the switch cabinet reaches the first safety threshold.

[0073] After starting the temperature and humidity regulating device according to the adjustment parameters in this step, it is determined whether the temperature and humidity regulating device has received a shutdown instruction; if so, the temperature and humidity regulating device is shut down; if not, the step of acquiring multiple sets of environmental temperature data and infrared images continuously collected in the switch cabinet within a preset period is performed. When the system receives a shutdown instruction, the system also determines whether the adjustment amount of the current environmental humidity and / or current temperature is greater than or equal to the preset second value and the preset third value respectively within the preset fourth time. If not, other temperature and humidity regulating devices are started, wherein other temperature and humidity regulating devices are regulating devices that are not working in the switch cabinet, the preset second value is the minimum value of the change of humidity data in the switch cabinet within the preset fourth time after the temperature and humidity regulating device is started in the switch cabinet, and the preset third value is the minimum value of the change of temperature data in the switch cabinet within the preset fourth time after the temperature and humidity regulating device is started in the switch cabinet.

[0074] In addition, in order to prevent the switch cabinet from being damaged by animals, resulting in large temperature differences inside the switch cabinet and the inability of the temperature and humidity control equipment to effectively adjust the humidity, the system can use an infrared camera to monitor the area outside the switch cabinet in real time. Specifically, the infrared camera is used to take real-time photos of the area around the switch cabinet, and the monitoring image of the current cycle is compared with the monitoring image of the previous cycle to determine whether there are animals around the switch cabinet. If it is determined that there are animals near the switch cabinet based on image recognition technology, it is further determined based on the monitoring images of the previous cycle and the current cycle whether the animals are approaching the switch cabinet. If it is determined that the animal is approaching, the system will send an alarm instruction to the alarm device, prompting the alarm device to issue an alarm message, thereby preventing the animal from continuing to approach the switch cabinet and preventing the animal from damaging the switch cabinet and causing changes in temperature and humidity inside the switch cabinet.

[0075] In order to prevent the switch cabinet door from being opened due to other factors (such as wind), causing large temperature changes in the switch cabinet, and the humidity value in the switch cabinet still cannot reach the normal range after long-term adjustment by the temperature and humidity control equipment, this system uses ultrasonic detection technology to monitor the closing status of the switch cabinet door, and closes the switch cabinet door through an automatic control device when the switch cabinet is not completely closed. The specific method is to select at least one marking point on the switch cabinet, send ultrasonic waves to the above-mentioned marking points through an ultrasonic transmitter, and compare the ultrasonic signal parameters emitted from each point with the ultrasonic signal parameters reflected from each point when the switch cabinet is in a completely closed state to determine the closed state of the switch cabinet. Adjust the automatic control device according to the closed state of the switch cabinet to close the switch cabinet door.

[0076] Based on the above Figure 2It can be seen from the implementation method that the present application provides a monitoring method for a switch cabinet. The scheme is automatically executed according to the established steps. First, the position of the temperature and humidity sensor for collecting the ambient temperature is set, and after obtaining the humidity adjustment instruction, it is determined that the current external environment of the switch cabinet is a low temperature environment. At this time, the humidity data in the switch cabinet needs to be adjusted, and the ambient temperature data and infrared images in the switch cabinet are automatically collected. Compared with manual data collection, the errors caused by the manual measurement process can be avoided, and the accuracy of the ambient temperature data and infrared images can be ensured; then, the temperature change trend in the switch cabinet is determined according to the data change between the ambient temperature data and the infrared image. Since the ambient temperature data and infrared images in the switch cabinet are automatically collected after the humidity adjustment instruction is triggered, the temperature change trend in the switch cabinet determined according to the data is more accurate. Since the temperature change trend in the switch cabinet is determined based on accurate data, it is possible to timely and accurately predict whether there is a safety risk in the components in the target switch cabinet based on the temperature change trend in the switch cabinet. When there is a risk in the components in the switch cabinet, the temperature and humidity adjustment device is started to adjust the temperature and humidity in the switch cabinet to prevent the occurrence of condensation. It can be seen that by automatically collecting data, determining the temperature change trend in the switch cabinet, and judging whether there are safety risks in components, the temperature and humidity adjustment equipment is started to avoid the untimely and inaccurate manual monitoring. It is possible to timely and accurately judge the abnormal temperature and humidity time in the switch cabinet in a low temperature environment, prevent condensation, and ensure the stable operation of the power system in the switch cabinet.
