This application claims priority of the Chinese Patent Application No. 202311379875.2, filed on Oct. 24, 2023, the entire contents of which are hereby incorporated by reference.
The present disclosure relates to the field of gas emergency devices, and in particular, to a method, an Internet of Things (IoT) system, and a medium for presetting emergency devices of smart gas.
The urban gas pipeline network is widely distributed, and when a fault occurs or a gas outage is carried out for maintenance, it will, to a certain extent, affect the gas consumption of gas users. Therefore, it requires a gas-based emergency gas supply device to temporarily satisfy the gas demand of gas users when the gas pipeline network is unable to adequately supply gas in time.
Aiming at the problem of emergency supply of gas in unexpected situations, the patent CN103234116B discloses a mobile system for emergency natural gas supply. The mobile system comprises a water-bath gasifier mounted on a skid-mounted vehicle, an air-temperature gasifier, and a natural gas inlet and outlet pipeline. The system is capable of providing a stable gas supply to users for a long period of time when the gas company repairs the pipeline network. But at present, it is usually only after a gas supply fault occurs that a device is urgently deployed from elsewhere to go to the area of the fault to provide emergency gas supply, and it often takes a certain period of time for temporary resumption of the gas supply from the time the shortage of gas supply begins to occur. If the fault occurs in a peak gas consumption period, it may not be able to fully meet the users' gas demand in time, which may cause more complaints from gas users.
Therefore, it is desirable to provide a method, an IoT system, and a medium for presetting emergency devices of smart gas to reasonably place an emergency gas supply device at a preset location, which helps to make timely dynamic deployment.
One of the embodiments of the present disclosure provides a method for presetting emergency devices of smart gas.

The IoT system may include a smart gas user platform, a smart gas service platform, a smart gas pipeline network safety management platform, a smart gas pipeline network sensor network platform, and a smart gas pipeline network object platform.

It is to be understood that for those skilled in the art, after understanding the principle of the system, it may be possible to arbitrarily combine individual modules or constitute a sub-system to be connected to other modules without departing from the principle.
In 210, gas supply and demand features may be determined based on node data and downstream user features of a gas pipeline network.
The gas pipeline network refers to a network structure consisting of gas pipelines of various pressure levels and branches thereof. The node data represents data related to gas features of each node in the gas pipeline network. For example, the node data may include pressure, temperature, flow rate, or the like, at different locations of the gas pipeline network. In some embodiments, the node data may be obtained through sensors of the smart gas pipeline network equipment object sub-platform.
A node in the gas pipeline network refers to a position that requires focused monitoring. For example, nodes of the gas pipeline network may include locations of the gas network that require focused monitoring, such as an entry point of the gas pipeline network, an inflection point of the gas pipeline network, a link points of the gas pipeline network, a gas outlet, etc.
In some embodiments, the downstream user features refer to feature data that reflects usage of gas by downstream users. The downstream users may include residential users, industrial users, commercial users, etc. The downstream user features may include gas usage time of users, a usage volume, gas pressure at the entry point, etc. In some embodiments, the downstream user features may be obtained through the smart gas pipeline network equipment object sub-platform.
The gas supply and demand features are feature parameters that represent a gas supply and demand situation. For example, the gas supply and demand features may include a difference between the gas supply and the gas demand.
When the gas supply and demand situation changes, the pressure of the gas pipeline network may also change. For example, when the gas supply meets the gas demand of users, the pressure of the gas pipeline network may remain relatively stable. When the gas supply exceeds the gas demand, the pressure of the corresponding gas pipeline may gradually decrease.
Therefore, the gas supply and demand features may also include a pressure change of the gas pipeline network. For example, the gas supply and demand features may include at least one of a branch pressure of the gas pipeline network on at least one continuous time point, a change rate of the branch pressure of the gas pipeline network, and a duration of reduction in gas pressure.
In some embodiments, the smart gas pipeline network safety management platform 130 may determine the gas supply and demand features of a region based on a change trend in the node data and the downstream user features of the gas pipeline network in the region during a time period. For example, gas supply features may be determined based on the node data, gas demand features may be determined based on the downstream user features, and the gas supply and demand features may be determined based on a difference between the gas supply features and the gas demand features. As another example, the pressure change in the gas pipeline network may be determined based on the node data and the downstream user features corresponding to the at least one continuous time point, and the gas supply and demand features may be determined based on the pressure change.
In 220, a plurality of gas emergency regions may be determined based on the gas supply and demand features.
The gas emergency regions refer to regions where emergency gas supply is required. For example, the gas emergency regions may include residential areas, commercial neighborhoods, and/or industrial areas, etc., that require emergency gas supply at different time points.
In some embodiments, the smart gas pipeline network risk assessment and management sub-platform may determine the gas emergency regions in various ways. For example, the smart gas pipeline network risk assessment and management sub-platform may determine the gas emergency regions by determining whether the gas supply and demand features of different regions reach a preset threshold.
In some embodiments, the smart gas pipeline network risk assessment and management sub-platform may determine a plurality of gas emergency regions based on a regional division of the gas pipeline network and the gas supply and demand features. More descriptions may be found in
In 230, location data and carrying data of a plurality of emergency devices may be continuously obtained.
The emergency devices refer to devices used for emergency gas supply. For example, the emergency devices may include a gas supply tank, etc. In some embodiments, the plurality of the emergency devices may be arranged in a distributed manner. In some embodiments, the emergency devices may be transported to a specified location by a vehicle.
The location data refers to data reflecting locations of the emergency devices. For example, the location data may include locations of vehicles in which the emergency devices are located. The carrying data refers to data reflecting carriage of the emergency devices. For example, the carrying data may include gas supply capacities of the emergency devices.
In some embodiments, the smart gas pipeline network maintenance engineering object sub-platform may remotely obtain the location data and the carrying data from positioning devices and sensors placed on the emergency devices.
In 240, a dynamic deployment scheme for the plurality of emergency devices may be determined based on the plurality of gas emergency regions, the location data, and the carrying data.
The dynamic deployment scheme refers to a program for deploying the plurality of the emergency devices. For example, the dynamic deployment scheme may include a method for presetting emergency devices of gas (e.g., presetting time and presetting locations, etc.). In some embodiments, the dynamic deployment scheme may include locations of the emergency devices on at least one time point.
In some embodiments, the smart gas pipeline network safety management platform 130 may determine the dynamic deployment scheme in various ways. For example, the smart gas pipeline network safety management platform 130 may determine the dynamic deployment scheme based on the plurality of gas emergency regions, the location data, and the carrying data based on preset rules. For example, the preset rules may include determining, based on the locations of the gas emergency regions and the location data of the gas emergency devices, candidate gas emergency devices that may reach the gas emergency regions within a desired time, and deploying the candidate gas emergency devices of which carrying data satisfies a gas supply condition to the gas emergency regions.
In some embodiments, the smart gas pipeline network safety management platform 130 may determine the dynamic deployment scheme for the emergency devices based on weighted distances between different gas emergency regions and device data of the emergency devices. More descriptions may be found in
In some embodiments, the smart gas pipeline network safety management platform 130 may determine the dynamic deployment scheme based on gas placement locations and device data through a device deployment model. More descriptions may be found in
In 250, a movement instruction may be generated based on the dynamic deployment scheme, and the movement instruction may be sent to the plurality of emergency devices.
The movement instruction refers to an instruction directing the emergency devices to move. For example, the movement instruction may include movement time and movement locations of the emergency devices, etc.
In some embodiments, the movement instruction may be generated by the smart gas pipeline network safety management platform 130 based on the dynamic deployment scheme. For example, the smart gas pipeline network safety management platform 130 may determine, based on the dynamic deployment scheme, a target gas emergency device that needs to move, and a movement destination and movement time of the gas emergency device. The smart gas pipeline network safety management platform 130 may generate, at least based on the movement destination and the movement time, the movement instruction, and send the movement instruction to the target gas emergency device.
In some embodiments, the smart gas pipeline network safety management platform 130 may send the movement instructions to different smart gas pipeline network maintenance engineering object sub-platforms; and then the gas pipeline network maintenance engineering object sub-platforms may send the movement instruction to the corresponding emergency devices.
In some embodiments of the present disclosure, determining the gas emergency regions that may exist at different time points by means of the gas supply and demand features, and determining the corresponding dynamic deployment scheme for the emergency devices can make the limited count of emergency devices be preconfigured at locations where insufficient gas supply may occur, and provide emergency gas supply to the gas emergency regions in time in case of insufficient gas supply, thereby effectively avoiding the problem of the emergency devices being dispatched too late, and guaranteeing the gas supply in time.
It should be noted that the foregoing description of the process is for the purpose of exemplification and illustration only and does not limit the scope of application of the present disclosure. For those skilled in the art, various corrections and changes to the process may be made under the guidance of the present disclosure. However, these corrections and changes remain within the scope of the present disclosure.
In some embodiments, the smart gas pipeline network safety management platform 130 may determine a regional division 310 of the gas pipeline network, and determine a plurality of gas emergency regions 340 based on the regional division and gas supply and demand features 320.
More descriptions regarding the gas supply and demand features may be found in
The regional division refers to a result of dividing the gas pipeline network. The regional division of the gas pipeline network may include at least one sub-region. The sub-region may include a region where at least one gas pipeline segment within the gas pipeline network is located.
In some embodiments, the smart gas pipeline network safety management platform 130 may determine the regional division of the gas pipeline network based on a size of a preset grid. The size of the preset grid may be determined based on experience. In some embodiments, the size of the grid may be selected based on actual needs. The smaller the grid, the greater the count of sub-regions into which the gas pipeline network is divided.
In some embodiments, the smart gas pipeline network safety management platform 130 may also divide the gas pipeline network based on a map corresponding to the gas pipeline network, for example, by drawing a dividing line along a roadway to divide the gas pipeline network into a plurality of sub-regions. In some embodiments, the regional division may be performed based on one or more parameters to divide the gas pipeline network into at least two sub-regions, such as an area size, a population density, an administrative division, an office building density, a residential building density, vertical and latitudinal coordinates, or the like, or any combination thereof. In some embodiments, the smart gas pipeline network safety management platform 130 may also determine the regional division of the gas pipeline network in other ways.
The gas emergency regions 340 may be determined in various ways. In some embodiments, the smart gas pipeline network safety management platform 130 may analyze the gas supply and demand features of each sub-region separately. When the gas supply and demand features of the sub-region meet a preset condition, the sub-region may be determined as the gas emergency region 340.
The preset condition may be a determination condition for evaluating whether the sub-region is the gas emergency region 340. For example, the preset condition may include that pressure of a gas pipeline segment of the sub-region on at least one continuous time point is lower than a preset threshold, etc. The pressure of the gas pipeline segment refers to an average value of pressures of all gas pipeline segments of the sub-region.
By determining the gas emergency regions 340, it is possible to deploy the emergency devices to the sub-regions in advance according to the dynamic deployment scheme when there is insufficient gas supply in certain sub-regions, avoiding safety hazards caused by directly increasing the pressure of the gas pipeline network, and reducing loss of gas caused by other majeure factors of the gas pipeline network due to high pressure.
In some embodiments, the gas supply and demand features may include a pressure change of the gas pipeline network of at least one continuous time point. The smart gas pipeline network safety management platform 130 may determine the gas emergency regions 340 corresponding to the at least one time period based on the pressure change of the gas pipeline network of the at least one continuous time point.
The pressure change of the gas pipeline network is used to characterize a pressure change over time within the gas pipeline segment. In some embodiments, the pressure change of the gas pipeline network may be represented by a vector as (A1, A2, A3, . . . ), wherein A1, A2, and A3 represent pressures of the gas pipeline segment at different time points, respectively.
In some embodiments, the pressure change of the gas pipeline network may include a pressure change rate, an amount of pressure change, a pressure reduction duration, etc. of the at least one continuous time point.
The pressure change rate refers to a rate at which the pressure changes relative to time. The amount of pressure change refers to a difference between a maximum value and a minimum value of the pressure over a time period. The pressure reduction duration refers to time during which the pressure continues to decrease.
In some embodiments, the smart gas pipeline network safety management platform 130 may determine the pressure change of the gas pipeline network in various ways. For example, the smart gas pipeline network safety management platform 130 may obtain the pressure change of the gas pipeline network based on a preset time by obtaining pressures of a plurality of continuous time points within the preset time through the smart gas pipeline network sensor network platform 140.
The preset time refers to a historical time period before current time.
The continuous time points refer to a plurality of continuous time points of a certain interval duration. The continuous time points may be historical time points when the gas is used.
The interval duration may be any duration, which may be determined according to the actual demand. For example, the interval duration may be one minute, ten minutes, etc.
In some embodiments, the continuous time points may be determined based on factors such as a peak period and an off-peak period of gas usage and seasons. For example, the continuous time points during the peak period of gas usage may be more closely spaced. Similarly, the continuous time points during the winter season may be more closely spaced. The peak period refers to a time period during the day when the amount of gas used exceeds a gas peak threshold. The off-peak period refers to a time period during the day when the amount of gas used is less than a gas trough threshold. The gas peak threshold and the gas trough threshold may be determined based on historical gas usage during a same time period.
The time period is a period of time that corresponds to at least one continuous time point. For example, if the continuous time points are historical 0:30, 1:30, 2:30, etc., the corresponding time periods may be 0:00-1:00, 1:00-2:00, 2:00-3:00, etc. in the future.
In some embodiments, the smart gas pipeline network safety management platform 130 may determine, based on the pressure change of the gas pipeline network of the at least one continuous time point, the gas emergency regions 340 corresponding to the at least one time period in various ways. For example, the smart gas pipeline network safety management platform 130 may determine the sub-region as the gas emergency region 340 in the at least one time period based on that the pressure change rate, the amount of pressure change, and the pressure reduction duration of the gas pipeline segment of the sub-region are greater than thresholds corresponding to the pressure change rate, the amount of pressure change, and the pressure reduction duration of the gas pipeline segment of the sub-region, respectively. The corresponding thresholds may be system defaults, manually preset values, etc.
It should be noted that the determined gas emergency regions of different time periods may be different. For example, the gas emergency regions in the morning may be four regions A, B, C, and D, and in the afternoon, the gas emergency regions may be six regions C, D, E, F, H, and J.
In some embodiments, the smart gas pipeline network safety management platform 130 may determine an assessment value of the sub-region based on the pressure change rate, the amount of pressure change, and the pressure change duration, and determine the sub-region of which the assessment value satisfies an emergency condition as the gas emergency region 340. The emergency condition may include that the assessment value is greater than a preset threshold. The preset threshold may be a system default value, or a manually preset value.
In some embodiments, the assessment value of the sub-region may be determined based on formula (1):
E=α
1
P+α
2
V+α
3
T (1)
wherein E denotes the assessment value of the sub-region, α1, α2, and α3 denote assessment weights, P denotes the pressure change rate, V denotes the amount of pressure change, and T denotes the pressure change duration.
In some embodiments, the assessment weights may be positively correlated with user features, historical complaint data, historical gas supply fault data of the sub-region, etc. For example, the more important the users of the sub-region, the greater the assessment weight; the greater the amount of historical complaint data, the greater the number of times of faults indicated by the historical gas supply fault data, and the greater the corresponding assessment weight. The greater the assessment weight, the higher the emergency response urgency of the sub-region.
In some embodiments, the smart gas pipeline network safety management platform 130 may adjust the assessment weights α1, α2, and α3 based on the actual demand to obtain adjusted assessment weights α1′, α2′, and α3′. For example, for a sub-region A, where the focus should be on the pressure change duration, the smart gas pipeline network safety management platform 130 may increase the value of a 3 based on the actual demand. As another example, for a sub-region B, the amount of pressure change may have less impact on the urgency of emergency response, then the smart gas pipeline network safety management platform 130 may reduce the value of a 2 based on the actual demand.
The user features refer to features of gas users of the sub-region. For example, the user features may include types of gas users, a count of gas users, etc. The types of gas users may include residential users, commercial users (e.g., a refueling station, a natural gas power plant, etc.), and industrial users (e.g., a factory that requires gas), etc.
In some embodiments, the types of gas uses may be determined based on a supply address corresponding to the gas pipeline segment. For example, the type of gas user corresponding to the gas pipeline segment with a supply address of a community may be determined as the residential user. It should be noted that different types of gas uses may correspond to different types of gas pipeline segments.
The historical complaint data refer to complaint data on insufficient gas supply reported by gas users during historical usage of natural gas. The historical gas supply fault data refers to data on a gas supply fault that occurs during historical gas transportation.
In some embodiments, the gas emergency regions 340 may also be related to user feedback data 330.
The user feedback data 330 refers to information related to gas usage reported by the gas users. For example, the user feedback data 330 may include complaints from the gas users about insufficient gas supply, feedback on gas usage experiences, etc.
In some embodiments, the gas users may send the user feedback data 330 to the smart gas service platform 120 through the smart gas user platform 110. Then the smart gas service platform 120 may send the user feedback data 330 to the smart gas pipeline network safety management platform 130 for aggregation, processing, and other related operations.
In some embodiments, a possibility that a certain sub-region is determined as the gas emergency region may be positively correlated with the amount of the user feedback data 330. For example, the more the user feedback data 330 of the certain sub-region, the greater the possibility that the sub-region is determined as the gas emergency region 340.
In some embodiments of the present disclosure, the user feedback is considered to ensure that the determined gas emergency region is more in line with the practical situation of gas usage, thereby improving the accuracy of the determined gas emergency region and facilitating the subsequent dynamic deployment scheme based on the actual practical situation according to the gas emergency region.
In some embodiments of the present disclosure, there may be differences in gas supply and demand in different sub-regions at different time periods (e.g., some sub-regions may have insufficient gas supply at midday, and some sub-regions may have insufficient gas supply at night). By determining the gas emergency region in line with the practical situation, the limited count of emergency devices may be configured in the reasonable locations in advance, so that the gas emergency region can be supplied with emergency gas during the corresponding time period, thereby meeting the needs of different users.
In some embodiments of the present disclosure, the plurality of gas emergency regions of the gas pipeline network can be determined through the regional division and the gas supply and demand features, so that the dynamic deployment scheme can be rapidly obtained, the emergency device can be deployed in the gas emergency regions in advance to avoid the impact of insufficient gas supply on the gas users, thereby balancing the demand for gas supply, and guaranteeing normal gas supply.
In some embodiments, the smart gas pipeline network safety management platform 130 may determine weighted distances 441 between different gas emergency regions; and determine a dynamic deployment scheme 450 for the plurality of emergency devices based on the weighted distances 441 and device data 442 of the plurality of emergency devices.
More descriptions regarding the gas emergency regions may be found in
The weighted distances 441 may be used to measure a correlation between different gas emergency regions. For example, the larger the weighted distance 441 between a gas emergency region A and a gas emergency region B, the smaller the correlation between the gas emergency region A and the gas emergency region B.
In some embodiments, the weighted distance 441 may be determined in various ways. For example, the weighted distance 441 may be obtained through prior knowledge. The smart gas pipeline network safety management platform 130 may preset the weighted distances 441 between different gas emergency regions based on the prior knowledge according to different scenarios. For example, the greater the physical distance between two gas emergency regions and the longer the time interval between the occurrence of gas emergency situations, the larger the weighted distance between the two gas emergency regions.
In some embodiments, the smart gas pipeline network safety management platform 130 may determine the weighted distances 441 of time intervals 411 and physical distances 412 of different gas emergency regions based on the gas emergency regions of different time points.
The time interval 411 refers to a time interval at which the gas emergency situations may occur in different gas emergency regions. In some embodiments, the smart gas pipeline network safety management platform 130 may determine the time interval 411 based on time at which the gas emergency situations occur in the different gas emergency regions.
The gas emergency situation refers to an emergency situation that affects or may affect the normal use of gas users due to insufficient or interrupted gas supply, and requires emergency measures.
The physical distance 412 refers to a route distance between different gas emergency regions, i.e., a distance along the street or road on the surface of the earth between different gas emergency regions. For example, the physical distance 412 may include a relative distance in latitude, longitude, coordinates, etc. between different gas emergency regions. In some embodiments, the smart gas pipeline network safety management platform 130 may identify the physical distances 412 between different gas emergency regions based on the latitudes and the longitudes of the different gas emergency regions through analysis and processing of third-party software.
In some embodiments, the smart gas pipeline network safety management platform 130 may determine the weighted distance 441 between a current gas emergency region and a next gas emergency region by weighting and summing the time interval 411 and the physical distance 412 of the current gas emergency region and the next gas emergency region based on weighted weights 430. The current gas emergency region refers to a gas emergency region where the gas emergency device is located, and the next gas emergency region refers to any gas emergency region that the emergency device needs to be deployed.
The weighted weight 430 refers to a weighting coefficient corresponding to the time interval and the physical distance.
In some embodiments, the weighted weight 430 may be determined based on preset rules.
Merely by way of example, the preset rules may be that the longer emergency gas supply time 415 in the current gas emergency region, the longer the emergency device needs to stay in the current gas emergency region, the later the emergency device travels from the current gas emergency region to the next gas emergency region, and the greater the weighted weight 430 corresponding to the time interval at this time. The higher the importance of the gas use corresponding to the next gas emergency region, the higher the need to prioritize the emergency response of the gas use. At this time, the influence of the physical distance may be less considered, and the users with higher degree of importance may be supplied with gas as soon as possible regardless of distance. Accordingly, the higher the importance of the gas user, the smaller the weighted weight 430 corresponding to the physical distance.
The emergency gas supply time 415 refers to predicted information related to the time for the emergency device to perform emergency gas supply. For example, the emergency gas supply time 415 may include a start time when the emergency gas supply is required, a duration of the emergency gas supply, etc. In some embodiments, the smart gas pipeline network safety management platform 130 may determine the current emergency gas supply time 415 based on a duration of the emergency device used in the gas emergency region during a same historical period.
The degree of importance of gas users is used to characterize a degree of importance of gas users in the gas emergency regions. The degree of importance of gas users may vary from one gas emergency region to another. In some embodiments, the smart gas pipeline network safety management platform 130 may perform statistical analysis (e.g., a statistical period may be the past week/month, etc.) on historical gas supply data of the gas pipeline network, determine a correspondence between different gas emergency regions and the degree of importance of different gas users based on gas consumption of users of different regions, and determine a user level reference table based on the correspondence. In some embodiments, the smart gas pipeline network safety management platform 130 may determine the degree of importance of the gas user based on the gas emergency region by querying the user level reference table.
In some embodiments, the smart gas pipeline network safety management platform 130 may determine the weighted distance 441 between two gas emergency regions based on the physical distance 411 between the two gas emergency regions and the time interval 412 required for emergency response, the user features 413, the historical gas supply fault data 414, and the emergency gas supply time 415 through the weight determination model 420.
The emergency response refers to increasing gas supply to the gas emergency region through the deployment of the emergency device.
The weight determination model 420 may be configured to determine the weighted distance. In some embodiments, the weight determination model 420 may be a machine learning model such as a deep neural network model.
The user features 413 are configured to reflect features of gas users. For example, the user features may include a type and a degree of importance of the gas user. In some embodiments, the user features 413 may include user features of each of the two gas emergency regions for which a weighted distance is to be determined.
The historical gas supply fault data 414 refers to data related to gas supply faults during historical gas supply. In some embodiments, the historical gas supply fault data 414 may include historical fault records of each of the two gas emergency regions for which the weighted distance is to be determined.
In some embodiments, the weight determination model 420 may be trained based on a large number of first training samples with first labels. In some embodiments, the first training samples may include sample physical distances and sample time intervals of a plurality of sets of sample gas emergency regions, sample user features corresponding to each set of sample gas emergency regions, sample historical gas supply fault data, and sample emergency gas supply time. The first training samples may be obtained from historical data. Each set of sample gas emergency regions may include two sample gas emergency regions for which a weighted distance is to be determined.
In some embodiments, the first labels may be the weighted distances between different sample gas emergency regions. The first labels may be determined by the smart gas pipeline network safety management platform 130. For example, historical dynamic deployment records may be determined by performing statistical analysis on historical gas supply records. Historical placement locations of the emergency devices may be determined based on the historical dynamic deployment records. Historical weighted distances may be inversely induced by software simulation or other approaches based on the historical placement locations, which are then determined as the first labels.
In some embodiments, the smart gas pipeline network safety management platform 130 may train the weight determination model based on the plurality of first training samples with the labels. For example, the plurality of first training samples may be input into an initial weight determination model. A loss function may be constructed based on output results of the initial weight model and the first labels, and parameters of the initial weight model may be updated based on the loss function through gradient descent or other approaches. The training may be completed when a training end condition is satisfied, and a trained weight determination model may be obtained. The training end condition may include that the loss function converges, a count of iterations reaches a threshold, etc.
In some embodiments, the weighted weights 430 may be determined based on the trained weight determination model 420. For example, the smart gas pipeline network safety management platform 130 may determine the weighted weights based on the weighted distances output by the weight determination model 420 and processed by software simulation, etc. In some embodiments of the present disclosure, determining the weighted weights of the gas emergency regions using the weight determination model can obtain more accurate results than those determined manually, saving costs and resources, and facilitating the further determination of the dynamic deployment scheme, thereby better meeting the user gas demand, improving gas user satisfaction, and effectively reducing user complaints.
In some embodiments of the present disclosure, the weighted distances may be comprehensively determined by the physical distances and the time intervals, to ensure that the calculated weighted distances are more in line with the actual gas supply situation, improving the accuracy of the subsequently determined dynamic dispatch scheme for the emergency devices.

For example, the device data 442 of the emergency devices may include locations and gas supply capacities of the emergency devices. The locations of the emergency devices refer to geographical locations of the emergency devices. The gas supply capacities refer to the amount of gas that the emergency devices can provide.
The device data 442 of the emergency devices may be obtained in various ways.

The positioning technology may include one of the Global Positioning System (GPS), Global Navigation Satellite System (GLONASS), Wireless Fidelity (Wi-Fi) positioning technology, or the like, or any combination thereof. The smart gas pipeline network safety management platform 130 may also determine the gas supply capacities of the emergency devices through a difference between an initial gas supply volume and an actual gas supply volume of the emergency devices. The initial gas supply volume refers to a total amount of gas that the emergency devices can provide under full load. The actual gas supply volume refers to an amount of gas that the emergency devices have already provided to the gas emergency regions.
In some embodiments, the smart gas pipeline network safety management platform 130 may determine movement paths of the emergency devices based on the weighted distances 441 between different gas emergency regions. For example, the emergency devices may move to the corresponding gas emergency regions in an ascending order of the weighted distances.
In some embodiments, the smart gas pipeline network safety management platform 130 may also determine start locations, end locations, the movement paths, and operating time of the emergency devices in different gas emergency regions based on the weighted distances 441 between the different gas emergency regions and the device data 442. The operating time of the emergency devices in different gas emergency regions may be determined based on the emergency gas supply time of the emergency regions.

In some embodiments, the smart gas pipeline network safety management platform 130 may group the plurality of the gas emergency regions based on various approaches, such as manual analysis, machine modeling, etc., and determine the corresponding gas placement locations 521 based on the grouped gas emergency regions. For example, a center point of each group of gas emergency regions may be determined as the gas placement location 521.
In some embodiments, the smart gas pipeline network safety management platform 130 may determine a clustering center 510 by clustering the gas emergency regions based on the weighted distances, and determine the placement locations 521 of emergency devices based on a location of the clustering center 510.
The clustering center 510 refers to a center point of a gas emergency region cluster. The gas emergency region cluster refers to one or more gas emergency region clusters obtained after clustering the gas emergency regions with a clustering algorithm.
In some embodiments, the smart gas pipeline network safety management platform 130 may determine the clustering center by clustering the gas emergency regions based on weighted regions.
