Description

Technical Field

[0001] This document relates to the field of computer technology, and in particular to a gas Internet of Things application system, implementation method, electronic device and storage medium. Background Art

[0002] Since 2000, the Internet of Things technology has developed rapidly. Basic technical conditions such as architecture design, sensor networks, communication technology, big data, cloud computing, and IT information security have been met. In the past five years, the standardization of Internet of Things technology applications has begun to develop in various fields. The system operation and management model of the energy industry has accelerated its transformation towards comprehensive standardization, deep digitization, and high intelligence.

[0003] The field of gas pipeline network is undergoing significant changes due to the influence of Internet of Things technology. The Internet of Things connects the sensors and mobile devices of the gas pipeline network into a whole, and uses artificial intelligence to convert data into knowledge, which will completely reshape the perception and fault warning of pipelines, and provide safety and technical guarantees for the coordinated development of the entire industry chain in the gas field.

[0004] Internationally, under the background of widespread consensus on the application of the Internet of Things, various gas companies have built smart gas-related systems with safe gas use and convenient services as their main functions for the purpose of serving their own businesses. Most of them rely on core technical capabilities such as the Internet of Things to create or are actively building full-scenario, full-process intelligent platforms and solutions for gas companies to achieve their own digital strategic goals and provide technical support for improving the overall capabilities of the industry, empowering the industrial ecosystem, and achieving industrial upgrading. However, whether in international or domestic gas companies, the Internet of Things systems are independently built, data is scattered, and there is an island problem.

[0005] Within gas companies, the IoT data involved in actual business can be divided into station IoT data, line IoT data, terminal IoT data, upstream IoT data, and vehicle logistics data, etc., with a total of 5 major categories and 36 subcategories, covering many types of equipment and a large scale (the number of gas users nationwide in 2023 will be 327 million, of which the number of natural gas users will be approximately 238 million, and the number of liquefied petroleum gas users will be approximately 53 million). There are many manufacturers involved, and the data collection methods, communication protocols, data formats, management and operation and maintenance modes of each system are different. There is no unified technical architecture, data access, management and operation and maintenance system, and management is difficult.

[0006] In summary, the urban gas Internet of Things system has the following main problems: a) Irregular collection and transmission of IoT data, and the lack of necessary information; b) Frequent system and equipment failures / failures; c) The need for safe and stable operation of the urban gas Internet of Things system; d) The IoT system is built independently, with scattered data distribution and serious islands. The key and core technical problem that caused the existing problems is the extraction of common parts of various IoT applications in the gas industry, and the lack of the top-level architecture of the IoT ecosystem of the gas transmission and distribution system.

[0034] System Example

[0035] At present, due to the lack of unified standards and architectural guidance, IoT data is increasingly facing heterogeneity problems, mainly including data heterogeneity, collection service heterogeneity, and device and application heterogeneity. As data collection continues to develop in a heterogeneous manner, user needs are also increasing, and users are showing a demand for multi-device linkage and multi-data fusion. In order to meet user needs, business applications have put forward higher requirements for the resource provision and processing capabilities of the IoT platform, and expect IoT services to accurately and intelligently provide the data and device resources required by applications and simplify application processing.

[0036] According to an embodiment of the present invention, a gas Internet of Things application system is provided. Figure 1 Schematic diagram of the gas Internet of Things application system according to an embodiment of the present invention.

[0042] User domain 18 is used to provide users with an access interface and a human-computer interaction interface to the gas Internet of Things application system, and to manage and maintain it. Specifically used for:

[0043] Provide individual users, organizational users and artificial intelligence users with access interfaces to the gas Internet of Things application system and different human-computer interaction interfaces, wherein a network interface or application programming interface is provided for the artificial intelligence user to directly interact with other physical entities in the gas Internet of Things application system.

[0044] The system further comprises:

[0045] The resource exchange domain is used to realize sharing and exchange of information resources within the gas Internet of Things application system and between other external systems, so as to realize collaboration between business application systems within the enterprise and information sharing between external systems of the enterprise.

[0046] The embodiment of the present invention proposes a six-domain model architecture and entities, and analyzes the interface relationship between them. As the top-level architecture design of the urban gas pipeline network Internet of Things application system, it will provide system designers with a system decomposition reference design, and also provide an important basis for the mutual compatibility, interoperability and resource sharing between different Internet of Things application systems. This reference technical architecture includes the target object domain, perception control domain, service provision domain, operation and maintenance management domain, user domain and resource exchange domain, such as Figure 2 In the reference technical architecture of the town gas IoT application system:

[0047] (1) Target object domain: mainly includes physical objects sensed by various sensors and, in some cases, controlled by specific actuators. In addition, labels (such as barcodes, QR codes, and radio frequency tags) can also be attached to certain physical objects (such as pressure regulating boxes, valve wells, and cameras). These physical objects are designated as physical entities. They are not only applicable to urban gas pipeline network applications based on the Internet of Things, but are also objects of interest to users in the user domain. The target object domain usually includes three types of physical entities: gas, pipelines and equipment facilities, and the surrounding environment of pipelines.

[0048] (2) Perception and control domain: includes entities such as sensors, actuators, tag identification, and IoT gateways. Sensors perceive the operating parameters and status of physical entities in the target object domain. Sensors can be selected based on the required measurement parameters or entity parameters in the target object domain. Actuators can operate and control related entities in the target object domain in an emergency to change their status or attributes. Sensors and actuators can interact with physical entities independently or collaboratively.

[0049] (3) Service provision domain: carries and provides the core functions and services of the urban gas network IoT system, meeting the needs of users in the user domain (such as humans and digital entities) for the urban gas IoT system. The service control domain provides basic services and business services. Basic services include data access, data storage, rule engine, data processing, object model configuration, monitoring point association and geographic information. Business services include plant operation monitoring, transmission and distribution network monitoring, early warning and balance analysis, surrounding environment monitoring, early warning analysis, user gas use services and abnormal alarms.

[0050] (4) Operation and maintenance control domain: Provide equipment operation and maintenance, system operation and maintenance, security and compliance management services for the urban gas network IoT system. The equipment operation and maintenance entity monitors the equipment operation status and provides management and maintenance services. The operation support entity and the security entity ensure the safe and reliable operation of the system. The regulatory supervision entity ensures that the service complies with relevant regulations.

[0051] (5) User domain: includes individual users, organizational users, and artificial intelligence users. Individual users and organizational users interact with the town gas IoT system through the machine interface (HMI). Artificial intelligence users are IoT terminal equipment facilities or perception control applications with artificial intelligence analysis capabilities, which directly interact with other entities in the town gas IoT system through network interfaces or application programming interfaces. Depending on the user's role, the system presents different content for the user to use.

[0052] (6) Resource exchange domain: In the resource exchange domain, information resources can be shared and exchanged between the urban gas Internet of Things system and other external systems. Resource acquisition includes data discovery entities, which discover and acquire information resources from other systems; resource interaction includes internal business applications and external resource interaction entities, which achieve collaboration with the enterprise's internal business application systems and information sharing with the enterprise's external systems through resource exchange.

[0053] The interface relationship between each domain is shown in Table 1.

[0055]

[0056]

[0057] The above technical solutions of the embodiments of the present invention are described in detail below in combination with examples and drawings.

[0058] (1) Leakage analysis

[0059] Locate the leakage point by analyzing the change characteristics of process parameters such as pressure and flow of the gas transmission and distribution system and the combustible gas leakage diffusion model. Identify the leakage conditions of the gas transmission and distribution system, and accurately locate the leakage point through the linkage of IoT equipment monitoring points. Guide correct repair and maintenance. Optimize the route and frequency of manual inspections.

[0060] Due to factors such as electrochemical corrosion, geological subsidence and third-party sabotage, gas transmission and distribution system leaks occur from time to time, which can cause significant casualties and property losses. Currently, gas leak detection is mainly based on vehicle and human patrols, which cannot monitor in real time, and the positioning method is single and inaccurate.

[0061] A large number of IoT sensors for temperature, pressure, flow, combustible gas concentration, wind speed, etc. are deployed at key locations such as gate stations, pipelines, valve wells, pressure regulating boxes, and user terminals in the gas transmission and distribution system. Users call the physical model management basic service of the service provider domain through the equipment operation and maintenance management module of the operation and maintenance control domain to complete equipment registration and measurement point binding, and generate physical model instances corresponding to the physical world. The data information obtained by the sensors and identification recognition of the perception control domain is uploaded to the service provider domain after processing by the IoT gateway, and the collected data is filtered, converted, cleaned, calculated, and stored in the data management entity center according to the rule engine. The service provider domain calls the business service of the transmission and distribution pipeline network monitoring and early warning and regional balance analysis service, and uses the characteristics of "leakage in the gas transmission and distribution system will inevitably destroy the balance state of process parameters such as system pressure and flow" to achieve accurate positioning of the leakage point and effective identification of the leakage amount with the help of flow balance model, simulation model, and combustible gas leakage diffusion model, and provide the analysis results to the user domain.

[0062] When a leak is found but the amount of leakage has not reached the warning value, the dispatcher of the gas supply company will inform the inspection personnel of the leak location and analysis results obtained by the IoT application of the gas transmission and distribution system, and guide the inspection personnel to go to the location of the leak for on-site confirmation, and perform the disposal operation according to the steps: on the one hand, determine the range of users that may be affected by the pressure reduction or valve closing maintenance, and notify and warn the residential users and industrial and commercial service users within the range; on the other hand, assign maintenance personnel to perform on-site maintenance. When it is confirmed that the amount of leakage has reached the warning value, the actuator of the system perception control domain closes the upstream valve of the leak point, and the system simultaneously transmits the information processed by the safety operation and maintenance management and compliance management modules of the operation and maintenance control domain to the relevant safety production management system and government safety supervision platform of the gas supply company in the resource exchange domain. The dispatcher of the gas supply company assigns emergency repair personnel to evacuate personnel and carry out on-site emergency repairs in accordance with the emergency plan and in accordance with the relevant requirements of the government and the fire department.

[0063] In addition, the equipment operation and maintenance management module in the system operation control domain tracks and monitors the operation status of IoT devices throughout the entire process, and provides information on IoT equipment facilities in abnormal states to gas supply companies and IoT service providers, completing the maintenance of faulty equipment and facilities through equipment operation and maintenance management. The system can also interact with internal business systems to optimize manual inspection routes and frequencies. Figure 3 shown.

[0064] The technical details of the embodiment of leakage analysis of the Internet of Things application in the gas transmission and distribution system are shown in Table 2.

[0065] Table 2 Technical details of the use case of leakage analysis in the IoT application of gas transmission and distribution system

[0066]

[0067] (2) Health diagnosis of voltage regulating equipment and facilities

[0068] Monitor the operating status of the pressure regulating equipment and facilities in the gas transmission and distribution system, and implement local self-diagnosis and remote control of the pressure regulating equipment and facilities based on business analysis. Implement real-time monitoring and remote control of the operating status of the pressure regulating equipment and facilities. Implement local self-diagnosis of faults / abnormalities of the pressure regulating equipment and facilities based on changes in the operating status parameters of the pressure regulating equipment and facilities. Guide the maintenance of the pressure regulating equipment and facilities based on the diagnosis results of the status of the pressure regulating equipment and facilities.

[0069] As one of the core components of the gas transmission and distribution system, pressure regulating equipment and facilities are located at the end of the gas pipeline network and are densely distributed in residential areas. Once an operational failure occurs, it will cause gas leakage, affecting the stable gas supply at the user end and inducing safety risk accidents, causing personal injury and property loss. Usually, gas supply companies use a combination of manual inspections and fixed-point operation and maintenance to control the operating status of a large number of pressure regulating equipment and facilities, which often have problems such as untimely management or excessive maintenance.

[0070] The IoT application of the gas transmission and distribution system collects real-time data such as the inlet pressure, outlet pressure, valve opening, temperature, etc. of the pressure regulating equipment and facilities through the perception control domain, and stores the data in the time series database of the gas IoT application system, which is monitored in real time by the functional services provided by the service provider domain. At the same time, the data is provided to the artificial intelligence users in the user domain, and the artificial intelligence users implement local self-diagnosis of abnormalities in the pressure regulating equipment and facilities based on changes in the operating status parameters of the pressure regulating equipment and facilities, and implement switching of the main and standby pressure regulating pipelines when the main pressure regulating pipeline fails. The results of the diagnosis and analysis of the status of the pressure regulating equipment and facilities are sent to the business service module of the service provider domain, and the transmission and distribution pipeline network monitoring, early warning and balance analysis services are used to further verify and analyze the abnormal status of the pressure regulating equipment and facilities, form a maintenance plan for the pressure regulating equipment and facilities, and guide the repair and maintenance of the equipment and facilities. The schematic diagram of the implementation example of health diagnosis of pressure regulating equipment and facilities in the IoT application of the gas transmission and distribution system is shown in the figure below. Figure 4 shown.

[0071] The technical details of the implementation example of health diagnosis of pressure regulating equipment and facilities in the Internet of Things application of the gas transmission and distribution system are shown in Table 3.

[0072] Table 3 Technical details of the implementation example of health diagnosis of pressure regulating equipment and facilities in the Internet of Things application of gas transmission and distribution system

[0073]

[0074]

[0075] (3) Gas confined space monitoring

[0076] Under certain conditions, the closed space where gas cannot diffuse and escape freely is monitored, leaks are quickly located, and relevant personnel are supported to work safely down the well. The system monitors and provides real-time alarms for combustible gas in the gas-enclosed space around the gas pipeline, reducing the safety risks caused by the accumulation of combustible gas in the gas-enclosed space. It supports relevant personnel to work in the gas-enclosed space, and provides continuous alarms when the working conditions of the gas-enclosed space are not met.

[0077] There are numerous gas-enclosed spaces around gas pipelines laid in cities, such as valve wells, sewage wells, rainwater wells, cable trenches, communication trenches, and underground pressure regulating boxes / cabinets. Factors such as third-party construction damage, corrosion, and pipeline construction quality pose a safety hazard to the safe operation of pipelines. Abnormal conditions that usually occur frequently in enclosed spaces around gas pipelines include gas leakage, displacement of manhole covers, unauthorized opening of enclosed boxes, flooding, and abnormally high temperatures. When gas leaks in a gas-enclosed space, the gas concentration increases rapidly due to limited space and spreads in a limited space. Once it encounters an open flame, a violent explosion will occur, directly endangering the lives of people on the ground and causing extremely serious damage to the city.

[0078] In the gas transmission and distribution system, a large number of multi-type IoT sensors and actuators are deployed in the gas confined space to monitor and manage the safety risks of the confined space in the surrounding environment of the pipeline. According to the operation characteristics of the gas pipeline network, the current status of data collection quality and the preset requirements of different collection frequencies, the IoT equipment and facilities in the gas confined space collect the parameters such as the concentration of combustible gas, the displacement of the manhole cover, the opening of the closed box, the liquid level, and the temperature in the confined space in real time. The surrounding environment monitoring and early warning service in the service provider domain analyzes and processes the monitoring data. When the parameters such as the concentration of combustible gas monitored in the gas confined space exceed the preset alarm threshold, the IoT application of the gas transmission and distribution system warns the gas supply enterprises and gas users in the user domain. After receiving the alarm signal, the on-duty personnel of the dispatching center can quickly locate the alarm position and push the relevant information of the alarm point to the pipeline network inspection staff for the relevant personnel to complete the safety assessment of entering the gas confined space. When the conditions for entering the gas confined space are not met, the system will provide continuous safety warnings, and the warning will be lifted after the conditions for safe entry into the gas confined space are fully met.

[0079] In addition, by calling the service entities such as equipment status management and point operation monitoring in the operation and maintenance control domain, the operation and management of IoT equipment and facilities in the gas confined space can be realized. Figure 5 shown.

[0080] The technical details of the embodiment of gas confined space monitoring using the Internet of Things in the gas transmission and distribution system are shown in Table 4.

[0081] Table 4 Technical details of the gas transmission and distribution system IoT application gas confined space monitoring example

[0082]

[0083] (4) Gas consumption monitoring and diagnostic analysis for large-volume users

[0084] Through the real-time data collection and analysis of gas consumption, pressure, temperature, alarm, etc. of large users, the gas consumption metering and abnormal behavior of users are monitored, analyzed and warned. Remote online monitoring of gas consumption is realized to ensure data integrity and accuracy. Comprehensive monitoring and analysis of gas consumption, metering instruments and user information are realized to determine whether the metering range is appropriate, and intelligently switch the range when necessary to ensure accurate gas metering. Forecast the gas consumption of users as input for dispatching and operation management, and guide the relevant operations of dispatching and operation. Data abnormality alarm, abnormal situations can be handled in time to ensure gas supply to users.

[0085] Compared with residential gas users, large-scale users have higher requirements for the continuous supply of natural gas due to their larger gas consumption and longer usage time. Unplanned natural gas supply interruption may cause immeasurable losses. Therefore, it is necessary to strengthen the monitoring and management of gas consumption of large-scale gas users to ensure safe and efficient gas supply to large-scale users.

[0086] The IoT application of the gas transmission and distribution system collects real-time data such as the flow, pressure, and temperature of natural gas from large users through the sensing control domain, and transmits the data through the wireless communication network. For security reasons, some gas IoT systems also use dedicated network lines to complete data transmission after completing data encryption and identity authentication. Based on the collected data, artificial intelligence users can directly conduct a comprehensive analysis of gas consumption, metering instruments, and user information on site to determine whether the metering range is appropriate, and intelligently switch the range when necessary to ensure accurate gas metering.

[0087] After the data collected on-site arrives at the service provider domain, the user gas usage service and abnormal alarm function will combine user type, industry attributes, historical gas usage data, accident data, etc. to model user portraits, realize the prediction of user gas usage, and serve as the input of dispatch operation to guide dispatch operation and provide support for the formulation of emergency supply guarantee plans. In addition, the user gas usage service and abnormal alarm function uses the user gas usage abnormality diagnosis model. On the basis of continuous verification and adjustment of the model in combination with real-time data, it warns of gas usage anomalies and guides gas supply companies and users to deal with anomalies in a timely manner. The schematic diagram of the implementation example of gas transmission and distribution system Internet of Things application large-scale user gas usage monitoring and diagnostic analysis is shown in the figure. Figure 6 shown.

[0088] The technical details of the implementation example of the Internet of Things application of gas transmission and distribution system for large-scale user gas consumption monitoring and diagnostic analysis are shown in Table 5.

[0090]

[0091] (5) Smart Gas Manager

[0092] With the help of smart devices, sensors and Internet technologies, we can monitor gas leaks, gas equipment conditions, gas usage and other situations in real time, and provide smart gas steward services to gas users through alarms, remote control and other means. We can monitor the status of gas equipment and leakage conditions in the household gas environment, and provide smart household gas safety services to residents through remote equipment monitoring and user safety reminders. With the help of smart IoT devices, we can provide residents with portable gas services.

[0093] Smart gas steward is an efficient and intelligent household gas safety solution for urban residents. This service is based on smart technology and IoT terminals such as gas monitoring equipment. It can not only prevent dangerous accidents such as gas leaks, but also improve energy efficiency and create a more convenient and comfortable home environment for residents. With the help of multiple types of sensors that have been connected to the IoT application of the gas transmission and distribution system and registered and associated, the household gas usage and key parameters represented by the concentration of combustible gas in the house are monitored in real time. The system access of IoT devices in the home environment is usually achieved by low-power wide area network technology. After a series of basic services for data processing and storage, the original collected data is forwarded to the user's gas service and abnormal alarm service, and the intelligent management and control of household safety is realized with the help of the linkage of IoT devices, that is, any potential gas leaks or abnormal conditions are detected by the combustible gas concentration sensor. Once an abnormality is detected, the smart device will immediately send an alarm to notify the user, and will be linked with other smart home devices such as smoke alarms, self-closing valves, smart range hoods and smart windows. While automatically cutting off the gas supply in the leaking or abnormal area, the windows are opened in time to exhaust the gas to prevent dangerous accidents such as fire or explosion and ensure the safety of residents. In addition, with the help of smart gas meters, convenient household services such as fee checking and payment can be provided to residential users through mobile phone applications or smart terminals deployed on the application network; residential users can also independently control the gas supply through remote control functions such as setting timed power on and off, thereby improving energy utilization efficiency.

[0094] For gas supply companies, after obtaining the alarm information pushed by the gas transmission and distribution system IoT application through the human-computer interaction interface, they can quickly respond to and effectively deal with the incident, such as arranging professional maintenance personnel to provide door-to-door service and troubleshooting. Figure 7 shown.
