Description

Technical Field

[0001] The present invention relates to the field of energy Internet of Things network technology, and in particular to an energy Internet of Things explosion-proof cooling integrated design method. Background Art

[0002] With the development of various new energy sources such as hydrogen energy and related technologies such as the Internet of Things, connecting related equipment in the energy field through the Internet of Things to make them work together, thereby realizing the functions required by the distributed intelligent measurement and control system of the energy Internet of Things has become an irreversible technological development trend in the future new energy and other comprehensive energy fields. Whether in new energy fields such as hydrogen production, storage, transportation, hydrogenation and hydrogenation, or in traditional energy fields such as coal, petroleum, chemicals and natural gas, many application scenarios have strict explosion-proof requirements, resulting in many new Internet of Things technologies and ordinary circuits cannot be directly applied, which seriously limits the development speed of Internet of Things technology in the energy field and its digitalization process.

[0003] Therefore, an integrated design method of explosion-proof cooling for energy Internet of Things is proposed to solve the above-mentioned problems. Summary of the invention

[0004] The present invention aims to provide an integrated design method for explosion-proof cooling of energy Internet of Things to solve or improve at least one of the above-mentioned technical problems.

[0005] In view of this, a first aspect of the present invention is to provide an integrated design method for explosion-proof cooling of energy Internet of Things.

[0006] The first aspect of the present invention provides an integrated explosion-proof cooling design method for an energy Internet of Things, wherein the energy Internet of Things includes a field-end device and an interactive device and a heat dissipation device connected to the field-end device. The design method includes the following steps: creating a topological network using the field-end device, the interactive device and the heat dissipation device as nodes; obtaining connection lines between each of the field-end devices and the interactive device and the heat dissipation device according to the working characteristics of the field-end device, and adding the connection lines to the topological network as links between nodes; demarcating explosive areas on the topological network according to the explosion-proof environment in which the energy Internet of Things is located, and setting a first explosion-proof area connected to the explosive area on each node corresponding to the field-end device; demarcating a second explosion-proof area connected to the first explosion-proof area on the topological network, aggregating the links corresponding to the connection relationship between the field-end device and the interactive device and the heat dissipation device, and setting the aggregated links in the second explosion-proof area;

[0007] Gradually decreasing pressures are marked on the second explosion-proof area, the first explosion-proof area and the explosive area to drive the refrigerant of the heat dissipation device to flow through the field-side equipment and reach the explosion-proof environment; and the energy Internet of Things is designed through the topological network.

[0008] In any of the above technical solutions, the second explosion-proof area can penetrate the edge of the explosion-prone area, and the position of the second explosion-proof area that penetrates the edge is determined according to the working characteristics.

[0009] In any of the above technical solutions, the step of demarcating the explosive area on the topological network according to the explosion-proof environment in which the energy Internet of Things is located specifically includes: obtaining the type of explosive gas contained in the explosion-proof environment, and taking the minimum concentration required for the explosion of the explosive gas of this type as a threshold; determining the edge in the current explosion-proof environment through the threshold, and enclosing the edge to form the explosive area; and projecting the explosive area onto the topological network according to the working characteristics.

[0010] In any of the above technical solutions, the interactive device and the heat dissipation device both construct the connection line with the field-end device through the second explosion-proof area; and the refrigerant inside the second explosion-proof area circumferentially wraps the connection line between the interactive device and the field-end device.

[0011] In any of the above technical solutions, the connection line of the interactive device and the connection line of the heat dissipation device have a first intersection point where they converge, and the converged connection lines have a plurality of second intersection points where they connect to the field-end device;

[0012] Wherein, the edge is located between the first intersection point and the second intersection point.

[0013] In any of the above technical solutions, the first explosion-proof area is connected to the explosive area through an opening, and the opening is used to unidirectionally transport the refrigerant inside the first explosion-proof area to the explosive area.

[0014] In any of the above technical solutions, the refrigerant is used to cool the field equipment in the first explosion-proof area; and the second explosion-proof area is used to continuously transport the refrigerant into the first explosion-proof area, and transport the pressurized refrigerant to the explosion-prone area through the opening.

[0015] In any of the above technical solutions, the interactive device, the heat dissipation device and the field-side device all adopt a non-explosion-proof design.

[0016] In any of the above technical solutions, the step of designing the energy Internet of Things through the topological network specifically includes: mapping the explosion-prone area to the explosion-proof environment of the energy Internet of Things according to the working characteristics; arranging the field-side equipment inside the mapped explosion-prone area, and defining the first explosion-proof area around the field-side equipment; arranging the interactive equipment and the heat dissipation equipment outside the explosion-prone area, and transmitting the connection line to the field-side equipment through the second explosion-proof area.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The use of non-explosion-proof circuits and equipment can significantly reduce production costs. Explosion-proof equipment usually requires the use of more expensive materials and more complex design standards, while the present invention allows the use of standard components and materials, thereby reducing initial investment and maintenance costs. Omitting specialized explosion-proof designs simplifies the engineering design and assembly process, which not only reduces the workload of design and assembly, but also shortens the implementation cycle of the project.

[0019] Through the design of the first explosion-proof area and the second explosion-proof area, the field-side equipment and connection lines are effectively isolated from the explosive environment, and the explosive gas is prevented from directly contacting the circuit, which greatly improves the safety of the system in the explosive environment. The pressure difference during the cooling process is used to provide additional explosion-proof protection for the field-side equipment. This pressure difference explosion-proof method not only prevents external flammable and explosive gases from entering the equipment, but also automatically discharges overheated gases by controlling the pressure difference to protect the equipment from overheating damage.

[0020] Additional aspects and advantages of embodiments according to the present invention will become apparent in the following description or may be learned through practice of embodiments according to the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The above and / or additional aspects and advantages of the present invention will become apparent and easily understood from the description of the embodiments in conjunction with the following drawings, in which:

[0022] Figure 1 is a flow chart of the method steps of the present invention;

[0023] Figure 2 It is a schematic diagram of the design of the energy Internet of Things on the topological network of the present invention. DETAILED DESCRIPTION

[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0026] See also Figure 1-Figure 2 , the following describes the energy Internet of Things explosion-proof cooling integrated design method of some embodiments of the present invention.

[0027] The embodiment of the first aspect of the present invention proposes an integrated design method for explosion-proof cooling of energy Internet of Things. In some embodiments of the present invention, such as Figure 1-Figure 2 As shown, the energy Internet of Things explosion-proof cooling integrated design method includes:

[0028] S101, creating a topological network with field-side devices, interactive devices and heat dissipation devices as nodes; the field-side devices include Internet of Things circuits; obtaining connection lines between each field-side device and the interactive devices and heat dissipation devices according to the working characteristics of the field-side devices, and adding the connection lines as links between nodes to the topological network.

[0029] Here, field devices usually include various sensors, actuators or other IoT devices that interact directly with the physical world to collect data or perform specific operations. For example, temperature sensors, humidity sensors, pressure sensors, etc.; these devices monitor or control specific parameters of their environment according to their design. The data is read and converted into digital signals through the circuits of the device for further processing by the system. Interactive devices are mainly responsible for processing the data collected by field devices, performing advanced data processing and decision making, such as data aggregators, gateways or central controllers; interactive devices receive data from field devices and perform necessary processing, such as analysis, storage or forwarding to higher-level data processing systems. They may also send control signals back to the field devices to adjust their operations. Heat dissipation devices are used to maintain the temperature of specific devices in the system to ensure that they operate within a safe and effective operating temperature range, such as fans, cooling systems or heat sinks; when the device generates heat during operation, the heat dissipation device removes the heat from the device through conduction, convection or radiation to prevent overheating.

[0030] As can be seen from the above, the connection line is defined as the physical or wireless communication path between the field equipment and the interactive equipment and heat dissipation equipment. These lines not only transmit data, but may also provide power. The connection line uses cables (such as twisted pair, optical fiber or power cord) or wireless signals (such as Wi-Fi, Bluetooth) to connect different devices. They ensure that the transmission of data and control signals is continuous and reliable, and sometimes provide power to support the operation of the equipment. Design an effective network topology based on the functions and geographical locations of the field equipment and their relationship with the interactive equipment and heat dissipation equipment. Consider using star, mesh, bus or tree topologies, depending on system requirements, reliability, scalability and cost. During the implementation phase, physical or wireless links are established to ensure that all nodes are properly connected according to the topology design. The network configuration should support the effective flow of data and allow rapid recovery in the event of a failure. Once the network is deployed, extensive testing is carried out to verify the efficiency of data flow, device response and fault recovery. Based on the test results, necessary adjustments and optimizations are made to ensure the optimal performance and reliability of the network.

[0031] Specifically, the steps for demarcating explosive areas on the topological network according to the explosion-proof environment of the Energy Internet of Things include:

[0032] The types of explosive gases contained in the explosion-proof environment are obtained, and the minimum concentration required for the explosion of the explosive gases of the type is used as the threshold. Specifically, the types of gases include hydrogen and natural gas, as well as flammable and explosive gases that may appear in the production operations of coal, petroleum and chemical industry.

[0033] The edge of the current explosion-proof environment is determined by the threshold, and the edge is enclosed to form an explosive area. Each gas has its own specific minimum concentration required for deflagration. The same minimum concentration is used as an optional threshold for demarcating the edge in order to distinguish the real hazardous area in the explosion-proof environment and provide a reference for explosion-proof treatment.

[0034] Project the explosive-prone area onto the topological network based on the working characteristics. By projecting the medical insurance area onto the topological network based on the working characteristics of the field-side equipment, the impact range of the IoT circuit on the explosive-prone area in actual work can be reflected.

[0035] For the specific description above, the system needs to be able to identify and measure the types of explosive gases in a specific environment, including hydrogen, natural gas, and other industrial gases. This is done by installing specific gas detectors that are highly sensitive and specific to specific gases. For each detected gas, the system needs to measure its concentration and compare it with the preset lower explosive limit (LEL). LEL refers to the lowest concentration that enables an air-gas mixture to burn or explode. When the concentration of any gas approaches or exceeds its LEL, the system will automatically trigger an alarm to notify the monitoring personnel to take emergency measures, such as starting the ventilation system, shutting down the power, or evacuating personnel. The system continuously records the type and concentration data of the detected gas, which can be used for post-analysis, identifying possible leak sources, optimizing production processes, or improving existing safety measures.

[0036] Real-time monitoring of the concentration of various explosive gases in a specific environment ensures that changes in the concentration of all relevant gases can be captured instantly. The edge of the hazardous area in the environment is determined based on the Lower Explosive Limit (LEL) of each gas as a threshold. When the gas concentration reaches or exceeds its LEL, the area is considered an explosive area. All designated explosive areas are marked in the monitoring system so that operators can clearly understand and identify the locations of these hazardous areas. When the gas concentration in any area reaches or exceeds the threshold, the system automatically triggers an early warning and initiates emergency measures, such as starting the ventilation system, cutting off the power supply, or starting the automatic sprinkler system.

[0037] Determine the minimum deflagration concentration (LEL) threshold of various explosive gases and monitor the gas concentration in the environment in real time to identify explosive areas. These areas are mapped in the topological network according to the working characteristics of the IoT field-side devices. In the IoT topological network, field-side devices, sensors, control systems and other network elements are included. The data of explosive areas are integrated into this network so that the system can fully understand and analyze the interaction between equipment and explosive areas. Use the topological network to conduct risk assessment to determine which IoT devices may cause dangers due to their proximity to explosive areas, such as electrical equipment that may cause sparks, or certain chemical reactions that may increase the risk of explosion. Design and implement specific safety measures based on the results of the risk assessment, such as increasing explosion protection, improving ventilation systems, or adjusting equipment layout to reduce the risk of explosion and fire.

[0038] As can be seen from the above, depending on the type of gas, appropriate sensors such as catalytic combustion sensors, infrared sensors or electrochemical sensors are used. Each sensor is based on different detection principles. For example, catalytic combustion sensors measure gas concentration by detecting the heat released when the gas burns, while electrochemical sensors detect gas by the change in current generated by the reaction of gas with electrodes. The data collected by the detector is transmitted to the central processing unit, where the software analyzes the data and compares it with the preset LEL value. If the detected gas concentration reaches or exceeds the LEL, the system will automatically activate the alarm and initiate emergency measures through the control system. The system is equipped with a communication interface that can transmit data and alarm information to the control room or mobile device in real time to ensure a quick response. At the same time, the system may also be integrated with other safety systems in the building or factory, such as automatically starting the sprinkler system or closing specific valves.

[0039] A variety of gas detection sensors are deployed in potentially hazardous areas. These sensors can perform high-precision concentration measurements for specific gases. The data collected by the sensors is transmitted to the central control system in real time. The system analyzes the data to determine whether the gas concentration at each monitoring point has reached its corresponding LEL. The control system is set with an LEL threshold for each gas. The system compares the monitored gas concentration with the preset threshold in real time. Once it is found that the gas concentration in a certain area reaches or exceeds the LEL, the area is designated as an explosive area. Explosive areas are clearly marked on the monitoring interface and visually distinguished by different colors or marks. At the same time, the system will send an alarm to relevant personnel and automatically initiate preset emergency measures. As environmental conditions change, the system continuously updates monitoring data and the delineation of explosive areas to ensure that all information is up to date and allows operators to respond and adjust according to actual conditions.

[0040] Use IoT technology, especially various gas detection sensors, to monitor the concentration of explosive gases in the working environment in real time. This data is transmitted to the central control system. The control system analyzes the collected gas concentration data, uses algorithms to determine the current explosive areas, and updates the information of these areas to the topological network. This can be displayed through a graphical interface, so that operators can clearly see which equipment is in the risk area. Use network analysis tools to evaluate the working characteristics of equipment in explosive areas and their potential risks, determine the degree of risk, and develop response strategies. Based on the analysis results, the system can automatically trigger safety warnings, such as automatically starting the ventilation system when the gas concentration reaches a dangerous level, or monitoring the potential impact of the equipment on the surrounding explosive areas when it is working, to ensure timely response.

[0041] Specifically, the working characteristics of the field equipment include the working temperature, its own explosion-proof treatment level, and the degree to which electric sparks may occur during operation. These characteristics should be taken into consideration so that the actual planning of explosive areas can be more in line with the actual situation.

[0042] As can be seen from the above, the key operating characteristics of the field equipment are collected and analyzed, including: operating temperature, the maximum and minimum temperature range of the equipment during operation. Explosion-proof level, the explosion-proof standards that the equipment meets, such as ATEX or IECEx explosion-proof certification, which define the level of explosive environment in which the equipment can safely work. The probability of electric sparks, the risk level of electric sparks during equipment operation, which usually depends on the design of the equipment and the electrical components used. Risk assessment, based on the collected equipment characteristics, risk assessment is carried out to determine the potential risks of using the equipment in a specific explosive area. Use algorithms and models to evaluate the safety of the interaction between equipment characteristics and the surrounding environment. Safety area planning, based on the results of the risk assessment, plan the best location of the field equipment in the factory or workplace. Ensure that high-risk equipment is away from areas with high concentrations of explosive gases, or adopt additional safety measures such as enhanced ventilation and explosion-proof facilities. Real-time monitoring and control, implement a real-time monitoring system to monitor the working status of the equipment and changes in the surrounding environment to ensure that all equipment operates within its safety parameters.

[0043] Use sensors and data collection systems to collect data such as operating temperature and electrical activity (such as sparks) from field-side equipment in real time. Analyze the collected data through an integrated software system, and use a preset risk assessment model to analyze the safety risks of each device. The system compares the actual operating parameters of the equipment with safety standards and explosion-proof levels. Visualize the risk assessment results in the monitoring system of the control center, such as displaying the risk level of the equipment through heat maps or color coding. Based on the analysis results, the automated control system can adjust the operating status of the equipment or initiate safety protocols, such as automatically shutting down the equipment when it detects that the temperature exceeds the safety limit or there is high-risk spark activity.

[0044] Furthermore, the working characteristic can be used as a mapping scale parameter of the projection.

[0045] From the above, it can be seen that the working characteristics of the field-side equipment are quantified into parameters that can be used for risk assessment and regional division. For example, the operating temperature can be converted into the corresponding thermal risk coefficient, the explosion-proof level can be converted into the safety level coefficient, and the probability of electric sparks can be converted into the electrical risk coefficient. Using the above mapping ratio parameters, combined with the actual operation data of the equipment, the comprehensive risk index of each device is calculated. This index will take into account the potential risks of the equipment in the current operating environment. Based on the calculated risk index, the system visualizes the risk level of each device and its surrounding areas. Through GIS (Geographic Information System) or other visualization tools, high-risk areas are clearly marked in the topological network. Based on the risk assessment results, optimize the equipment layout, adjust the operating protocol, or strengthen safety measures. For example, keep high-risk equipment away from areas with high concentrations of explosive gases, or add additional monitoring and emergency equipment.

[0046] Real-time data about the equipment's operating status (such as temperature, current, etc.) is collected through sensors installed on the field-side equipment. At the same time, the equipment's design parameters (such as explosion-proof level and historical fault data) are obtained from the safety database. The collected data and design parameters are converted into mapping ratio parameters through a predetermined formula. For example, the explosion-proof level is converted into a safety level coefficient according to a standardized formula, so that a higher explosion-proof level produces a lower coefficient, indicating higher safety. Combined with the mapping ratio parameters and environmental monitoring data (such as gas concentration), a risk assessment model is used to calculate the risk index of each device and its surrounding area. The model may be a simple model based on weighted summation, or include more complex statistical and machine learning algorithms. A graphical interface is used to display the risk level of each device and the boundaries of the explosive area. When the risk level of the equipment exceeds the safety threshold, an alarm is automatically triggered and the operator is notified or the preset safety procedure is automatically executed.

[0047] Specifically, the interactive device is a remote device or a local device far away from the explosive area, which can be used for power supply or data interaction of the field-side device, and the connection line of the interactive device is optical fiber and / or power cable.

[0048] As mentioned above, the interactive device is responsible for collecting data collected by field-side devices, such as sensors and actuators. This data may include monitoring data such as temperature, pressure, flow, or equipment status and alarm information. The interactive device is also responsible for processing the data, including data aggregation, analysis, and decision support, and then sending commands back to the field-side device for control operations. The interactive device provides the necessary power to the field-side devices through the power supply cable, especially those devices that require continuous power to maintain operation, such as certain types of sensors and control systems. The interactive device can remotely monitor and control the operation of the field-side equipment to achieve system optimization and fault prevention. This includes remote fault diagnosis, system upgrades, and configuration adjustments.

[0049] Using optical fiber for data transmission can provide a high-speed, high-bandwidth and anti-interference communication method. Optical fiber is particularly suitable for transmission over long distances and at high data rates, ensuring that data is conveyed quickly and safely. The use of optical fiber also avoids spark problems that may be caused by electrical signals in explosive environments, improving the safety of the system. Supply cables are designed to stably and reliably deliver power to field equipment, especially in applications with large power requirements. These cables usually have a high degree of insulation to prevent electrical failures. Interactive equipment is usually integrated in a control room or data center, which can centrally manage the operation of the entire system. Such a layout helps optimize resource utilization and simplify maintenance and upgrade operations. Through an advanced software platform, operators can receive data in real time, analyze it, and respond based on system status or predictive models. By placing interactive equipment away from explosive areas and using optical fiber and supply cables, the entire system is designed with safety isolation in mind. This design strategy reduces the risk of safety accidents and ensures the continuity and stability of operations.

[0050] In any of the above embodiments, the connection line of the interactive device and the connection line of the heat dissipation device have a first intersection at which they converge. Through the first intersection, the connection line and the refrigerant delivery pipeline of the heat dissipation device can be combined and then transported together to the explosive area; and the converged connection line has multiple second intersections for connecting to field-end devices. Since multiple energy Internet of Things will be set up in the explosive area, the field-end devices can be powered in parallel through multiple second intersections, and refrigerant for heat dissipation can be transported.

[0051] The edge is located between the first intersection and the second intersection. By processing a certain point of the convergence section between the first intersection and the second intersection to coincide with the edge, it is possible to avoid setting up complicated lines at the edge of the explosive area as much as possible. At the same time, a sensor for detecting the actual concentration of explosive gas can be set at the corresponding coincidence point, so as to adjust the position of the interactive device and the heat dissipation device relative to the explosive area to avoid interference from the external environment, such as temperature differences in different seasons or different regions.

[0052] In this embodiment, the system delivers both electricity and refrigerant to the field-side equipment through a common transmission network. This integrated approach simplifies pipeline layout and reduces installation and maintenance costs. All power and refrigerant transmission lines converge at the first intersection, which acts as a centralized control center responsible for allocating resources to different field-side equipment. This design improves the operating efficiency and response speed of the system. Multiple connecting lines extending from the first intersection have multiple second intersections in the explosive zone, which are connected to each field-side equipment. Each second intersection can supply power and transport refrigerant in parallel according to the needs of the connected equipment. The system manages power supply and refrigerant delivery simultaneously, ensuring that all equipment operates at the optimal operating temperature while meeting its power needs.

[0053] The system adopts a network design that combines centralized and distributed networks. The first node serves as the main node to control the main resource allocation, while multiple second nodes serve as distribution nodes to allocate resources to specific equipment according to actual needs. Refrigerant and electricity are transported through the same transmission pipeline or adjacent pipelines, and the design ensures the efficiency and safety of both transmissions. Refrigerant pipelines usually require special insulation and safety measures to prevent leakage or potential reactions with explosive gases. The automated control system monitors and adjusts the resource allocation of the first node and the output of each second node to ensure that the system operates according to preset parameters, such as power load and refrigerant demand. The system has a built-in fault detection and response mechanism. Once an abnormality in the transmission line or equipment is detected, the problem area can be quickly isolated, resources can be redeployed, or emergency response procedures can be initiated.

[0054] Avoiding complex wiring at the edge of explosive areas reduces the risk of wiring damage and potential ignition sources. This layout strategy increases the overall safety and reliability of the system. Install explosive gas concentration sensors at the intersection of the collection section and the edge to monitor gas concentration in real time and ensure that system operators can quickly respond to potential dangerous gas accumulation. Based on the data detected by the sensors, the system can adjust the location of interactive devices and heat dissipation devices to ensure that they are always in a safe area and away from areas with high concentrations of explosive gases. The dynamic adjustment of equipment location can also be optimized according to changes in environmental conditions in different seasons or different regions, such as temperature, humidity, etc., to maintain stable operation of the system.

[0055] Gas concentration sensors are deployed at the edge of the converging section between the first intersection and the second intersection. These sensors can collect gas concentration data in the environment in real time and transmit the data to the central monitoring system. The central monitoring system analyzes the sensor data in real time to assess the safety status of the explosive area. Once the gas concentration is detected to be close to or exceeds the predetermined safety threshold, the system will initiate an early warning and notify the operator to take necessary measures. Based on the gas concentration and external environmental data, the system automatically or manually adjusts the position of the interactive equipment and the heat dissipation equipment. This adjustment is achieved by mechanically moving the device or adjusting the equipment operating parameters. The system automatically adjusts the equipment settings based on the environmental data (such as temperature and humidity changes) collected from the weather station or built-in climate monitoring equipment to optimize the equipment's operating efficiency and safety.

[0056] S102, demarcating explosive areas on the topological network according to the explosion-proof environment in which the energy Internet of Things is located, and setting a first explosion-proof area connected to the explosive area on each node corresponding to the field-end device.

[0057] Here, explosive areas are delineated in the topological network based on the location of the field-side equipment and specific conditions of the surrounding environment (such as gas type, concentration, temperature, etc.). These areas are determined based on the minimum explosive concentration (LEL) of the gas and other relevant safety data. A first explosion-proof area is set on each field-side equipment node in the topological network, which represents the potential explosive environment directly related to the equipment. This area is defined based on the characteristics and operating status of the equipment. For example, equipment that handles flammable gases will have a larger first explosion-proof area. Specific safety measures are implemented in each first explosion-proof area, such as enhanced explosion-proof measures, explosion-proof equipment housings, additional monitoring and control systems, etc., to prevent any conditions that may lead to explosions. The environmental conditions of each first explosion-proof area, such as gas concentration and temperature, are continuously monitored, and the operating parameters are automatically adjusted or safety warnings and emergency response procedures are triggered based on the monitoring data.

[0058] As can be seen from the above, various sensors (such as gas detectors, temperature sensors) are used to collect key operating data and environmental parameters around each field-side device. By analyzing the collected data, the first explosion-proof area of ​​each device is dynamically divided and adjusted. This process involves complex data processing and model calculations to ensure accurate delineation of the area. Based on the delineated first explosion-proof area, preset safety measures are implemented, including but not limited to automatically shutting down system operations, activating fail-safe mode, or starting the emergency ventilation system. The system continuously monitors the status of each first explosion-proof area and makes necessary adjustments based on real-time data and predetermined rules to adapt to environmental changes or respond to emergencies.

[0059] In any of the above embodiments, the first explosion-proof area is enclosed by a separately set sealed box to prevent the field-side equipment inside the sealed box from contacting the explosive gas in the explosive area outside the sealed box, thereby avoiding explosions in the energy Internet of Things group. And because of the isolation effect of the sealed box, the field-side equipment does not need to undergo special circuit explosion-proof treatment, so that ordinary circuit structures can also be directly applied to the explosion-proof environment of the present invention, reducing the design difficulty at the design end and the production cost at the production end.

[0060] In this embodiment, the sealed box is designed to physically isolate the field-side equipment inside it from direct contact with explosive gases that may exist outside. This ensures that the operating environment of the internal equipment is not affected by external explosive gases. Since the sealed box provides the necessary protection, the field-side equipment can use ordinary circuit structures without expensive explosion-proof treatment. This reduces the complexity and cost of design and manufacturing. The sealed box not only prevents the infiltration of explosive gases, but also protects the internal equipment from dust, moisture and other environmental factors, thereby improving the reliability and service life of the equipment. Since the equipment is in a sealed environment, the maintenance requirements are reduced, and the frequency of cleaning and inspection is also reduced accordingly, further reducing operating costs.

[0061] Sealed boxes are usually made of explosion-proof materials with high mechanical strength and chemical stability. They have sufficient sealing performance to resist external pressure changes and chemical corrosion. The box design includes sealed doors, observation windows and necessary interfaces such as cable and pipe entrances, which are equipped with special sealing devices to prevent leakage. The sealed box is airtight before and after installation to ensure that there are no tiny leaks. This is usually done by applying a pressure difference and detecting pressure changes. Although the sealed box prevents the intrusion of external gases, the control of internal temperature and humidity is also very important. It may be equipped with internal air conditioning or dehumidification equipment to ensure that the equipment operates in the best environment. Smoke detectors, temperature sensors and humidity sensors are installed inside the sealed box and connected to the central monitoring system. Once an abnormal situation is detected, such as excessive temperature or smoke is detected, the system will automatically alarm and initiate emergency measures.

[0062] In any of the above embodiments, the first explosion-proof area is connected to the explosive area through an opening, and the opening is used to unidirectionally transport the refrigerant inside the first explosion-proof area to the explosive area. The opening is a one-way valve located on the sealed box, which can allow the refrigerant inside the sealed box to flow out to the explosive area.

[0063] In this embodiment, the one-way valve allows the refrigerant to flow from the inside of the sealed box to the external explosive area, but prevents the external environment (such as explosive gases and other pollutants) from entering the inside of the sealed box. By allowing the controlled outflow of the refrigerant, the one-way valve helps maintain the pressure balance in the sealed box and prevents the sealing performance from being reduced or the structure from being damaged due to excessive pressure. The outflow of the refrigerant not only delivers a cooling effect, but also helps control the temperature of the explosive area, thereby reducing the risk of explosion.

[0064] The sealed box is designed as a completely closed structure, equipped with the necessary refrigerant delivery system and one-way valve. The box material selection can resist the chemical and physical effects of explosive environments. The one-way valve is usually made of special materials, such as stainless steel or other corrosion-resistant materials, to ensure long-term stable operation. The valve is designed so that it only allows the refrigerant to flow out from the inside, but does not allow external air or gas to flow in. The valve usually contains spring-loaded or gravity-operated mechanical parts that automatically open when the internal pressure exceeds a certain threshold, allowing the refrigerant to flow out, but remain closed when the external pressure tries to push the valve open. The flow and pressure of the refrigerant are precisely managed by the control system inside the sealed box. The system automatically adjusts the opening degree of the valve according to the pressure difference between the inside and outside of the sealed box to ensure that the refrigerant flow is stable and sufficient to provide the necessary heat dissipation. Pressure and temperature sensors are installed in the sealed box to monitor the internal environment in real time. Any abnormal conditions, such as excessive pressure or abnormal temperature, will trigger a safety alarm and adjust or completely close the valve through the control system.

[0065] S103, demarcate a second explosion-proof area connected to the first explosion-proof area on the topological network, aggregate the links corresponding to the connection relationship between the field-side device and the interactive device and the heat dissipation device, and set the aggregated links in the second explosion-proof area. Through the aggregation process, the connection lines pointing to the same field-side device can be merged for a concise display in the topological network. At the same time, in the actual on-site construction, the connection lines connected to the same field-side device can be isolated from the explosive gas in the explosion-proof environment by using a second explosion-proof area, which further ensures the explosion-proof effect.

[0066] Here, the second explosion-proof area, as a logical extension of the first explosion-proof area, covers the field-side equipment and all the connection lines between it and the interactive equipment and heat dissipation equipment. This area is designed to contain all connections pointing to the same field-side equipment to ensure centralized management and explosion-proof isolation. In the topological network, multiple connection lines pointing to the same field-side equipment are aggregated. This not only simplifies the view of the network, but also reduces the complexity in the field physical layout, making the overall design simpler and easier to maintain. The aggregated links are concentrated in the second explosion-proof area, which is specially designed to block direct contact between explosive gases and equipment to improve the safety of the system.

[0067] As can be seen from the above, the design of the second explosion-proof area is based on a detailed assessment of the potential risks in the explosive environment. This area is usually set up around the field equipment, including the entrances and exits of all cables and pipes, using high-standard sealing technology to ensure that there is no gas leakage. During the design of the topological network, the links leading to the same field equipment are logically aggregated through software tools or manually. Aggregation can be based on the physical characteristics of the link (such as cable type, transmission rate, etc.) and safety requirements (such as maximum allowable distance, protection level, etc.). In the second explosion-proof area, all links and connection points are explosion-proof, such as using explosion-proof cables, pipes and joints. In addition, an automatic monitoring system may be set up to detect potential risks such as gas leaks and temperature changes, and implement corresponding safety protocols. The second explosion-proof area is designed to facilitate maintenance and inspection. The layout of the aggregated link simplifies the inspection process and reduces maintenance costs and downtime. Regular maintenance ensures that all explosion-proof measures are effective and prevents any safety accidents.

[0068] In any of the above embodiments, the second explosion-proof area can penetrate the edge of the explosive area, and the position of the second explosion-proof area that penetrates the edge is determined according to the working characteristics. By the second explosion-proof area penetrating the edge of the explosive area, the field-side equipment in the explosive area and the heat dissipation equipment and interactive equipment outside the explosive area can be connected.

[0069] In this embodiment, the second explosion-proof area serves as a safe passage, connecting the field equipment located in the high-risk explosion zone with the heat dissipation and interaction equipment located in a relatively safe area. This allows data and energy to flow safely between high-risk and low-risk areas. The second explosion-proof area uses specific explosion-proof measures (such as explosion-proof sealing and isolation technology) to ensure that explosive gases or other hazardous substances do not leak into the equipment operation area, while preventing external factors from affecting the equipment in the explosion-prone area. The effective connection of the heat dissipation equipment ensures that the field equipment can maintain a safe operating temperature range even in an explosive environment, avoiding safety problems caused by overheating.

[0070] The design of the second explosion-proof area adopts high-standard explosion-proof materials and technologies, such as the use of explosion-proof cables and pipes, and specialized sealing technology to ensure that all connections through this area will not become a potential source of ignition of explosive gases. According to the working characteristics of the field-side equipment (such as temperature, electrical characteristics, etc.) and the specific conditions of the explosive area, the system can dynamically adjust the configuration and location of the second explosion-proof area. By using sensors and control systems to monitor environmental conditions and equipment status, ensure rapid response when risks change. The heat dissipation equipment is connected to the field-side equipment through the second explosion-proof area, which is equipped with necessary heat dissipation pipes or cooling systems to effectively remove heat from the equipment and prevent the equipment from overheating. Data and energy are safely transmitted through the second explosion-proof area, using optical fiber or specially designed power lines, which not only ensures the safety of transmission, but also improves transmission efficiency.

[0071] In any of the above embodiments, both the interactive device and the heat dissipation device establish a connection line with the field-side device through the second explosion-proof area. Placing the connection line part in the second explosion-proof area can perform common explosion-proof treatment, reducing the site occupation of the energy Internet of Things.

[0072] The refrigerant in the second explosion-proof area circumferentially wraps the connection line between the interactive equipment and the field-side equipment. The circumferential wrapping of the refrigerant can form an additional isolation protection between the connection line and the explosive gas.

[0073] In this embodiment, all connection lines (including power, data and refrigerant transmission lines) are placed in the second explosion-proof area and protected by unified explosion-proof measures, such as using explosion-proof cables, explosion-proof conduits and special explosion-proof connectors. Centralizing the connection lines in the second explosion-proof area not only simplifies the layout, but also reduces the overall site occupancy, making the deployment of the system more efficient and economical. Unified explosion-proof measures ensure the safety of the connection lines in explosive environments and reduce safety risks caused by equipment failures or external factors. The centralized line layout facilitates the maintenance and overhaul of the system. Maintenance personnel can complete the inspection and repair of all connection lines in one area, improving maintenance efficiency.

[0074] All lines within the second explosion-proof zone are made of materials and designs that meet explosion-proof standards. This includes explosion-proof cables and pipes, as well as designs that can prevent spark generation or electromagnetic interference.

[0075] Environmental monitoring equipment, such as gas detectors and temperature sensors, are installed in the second explosion-proof area to monitor environmental conditions in real time and ensure that the connection lines operate in a safe environment. By connecting to the central control system, the second explosion-proof area can dynamically adjust operating parameters based on the monitored data, such as adjusting the working intensity of the cooling system or adjusting the power supply to respond to environmental changes or prevent potential safety risks. Explosion-proof safety doors and valves are set at the access points of the second explosion-proof area to ensure that in the event of an emergency, the connection between the explosive area and the outside world can be quickly cut off to prevent the spread of danger.

[0076] The refrigerant wraps around the connection line to help manage the heat generated by the current passing through the line, maintain the connection line in a safe temperature range, and prevent overheating. The presence of the refrigerant is not only used for cooling, but also acts as a physical barrier to prevent external explosive gases from directly contacting the electrical connection line, thereby reducing the risk of sparks or hot spots caused by electrical faults triggering explosions. By combining the refrigerant with the protection, the need for additional explosion protection measures, such as more complex isolation designs or additional cooling systems, is reduced, thereby simplifying the overall system design. Meeting both cooling and explosion protection requirements at the same time improves the operating efficiency and safety of the system and reduces operating and maintenance costs.

[0077] The refrigerant circulates through a specially designed piping system that wraps around the connection lines. The refrigerant system is designed as a closed loop to ensure that the refrigerant does not leak into the external environment. As the refrigerant flows through the pipes, it absorbs the heat generated by the connection lines. Through the principle of heat exchange, the refrigerant removes the heat from the connection lines and maintains the temperature of the lines within a safe range. The materials and design of the refrigerant pipes meet explosion-proof standards and can resist external impact and chemical corrosion. The pipes act as a physical barrier to prevent explosive gases from coming into direct contact with the wires. The system's built-in sensors monitor the pressure, temperature and flow rate of the refrigerant to ensure the normal operation of the refrigerant system. Any abnormality will trigger an alarm and the refrigerant flow will be adjusted or shut down through the automatic control system to prevent system failure.

[0078] In any of the above embodiments, the refrigerant is used to cool the field-side equipment in the first explosion-proof area. The refrigerant is not only used to isolate the field-side equipment and the connection lines of the interactive equipment from gas explosion, but also used for cooling and heat dissipation during the operation of the field-side equipment.

[0079] The second explosion-proof area is used to continuously transport refrigerant to the first explosion-proof area, and transport the pressurized refrigerant to the explosive area through the opening. Since the refrigerant heats up after contacting the hotter field-side equipment, the refrigerant in the sealed box will further increase its pressure due to thermal expansion, and thus be discharged through the one-way valve. Moreover, since the further increased pressure can prevent the explosive gas with lower external pressure from entering the sealed box, a pressure difference protection isolation is formed, which further improves the explosion-proof level of the field-side equipment inside the sealed box.

[0080] In this embodiment, the refrigerant is directly used for heat dissipation of the field-side equipment, helping to maintain the equipment within a safe operating temperature range. This prevents performance degradation or damage due to overheating of the equipment, especially in high-temperature explosive environments. The refrigerant is also used as an explosion-proof isolation layer to prevent the connection lines of the field-side equipment and the interactive equipment from directly contacting explosive gases, thereby reducing the risk of explosions caused by electrical failures. By using refrigerant as an isolation medium, not only the cooling efficiency of the system is enhanced, but also the overall safety of the system is improved, reducing accidents caused by environmental factors.

[0081] The refrigerant circulates through a closed loop system, which usually involves a compressor, expansion valve, condenser and evaporator. The refrigerant is compressed and circulated in the system, absorbing heat at the evaporator and releasing heat at the condenser. The refrigerant around the equipment at the field absorbs the heat generated by the equipment at the evaporator due to its physical properties. In this process, the refrigerant changes from liquid to gas, taking away the heat. The gaseous refrigerant is then compressed and transferred to the condenser, where it releases heat and re-liquefies, ready to be recycled again. The pipes and components of the refrigerant system are designed to be explosion-proof to prevent accidental leakage or damage caused by external factors such as impact. These pipes are usually covered or embedded in a protective layer to add additional physical barriers to prevent explosive gases from coming into contact with electrical components. Modern refrigerant systems are equipped with sensors and control units that can monitor the temperature, pressure and flow state of the refrigerant to ensure that the system operates stably according to the designed parameters. The control unit can automatically adjust the operation of the compressor, the opening and closing of the valves, etc. to optimize the heat dissipation effect and energy efficiency.

[0082] The equipment in the second explosion-proof area is responsible for transporting the refrigerant to the first explosion-proof area (inside the sealed box) and increasing the pressure during transportation to ensure that the refrigerant has sufficient pressure to pass through the one-way valve before reaching the equipment. The refrigerant heats up after contacting the running field-side equipment, and the pressure increases due to thermal expansion. This pressure regulation is the key to the system and is used to maintain the pressure inside the sealed box higher than the external environment, thereby preventing the entry of external explosive gases. As a control element, the one-way valve only opens when the internal pressure exceeds a certain threshold, allowing the refrigerant to discharge while preventing external gas from entering. The active regulation mechanism of the refrigerant pressure is used to form an effective pressure difference protection isolation, which enhances the explosion-proof level of the field-side equipment inside the sealed box.

[0083] The refrigerant is compressed and delivered to the sealed box through a cooling system (which may include a compressor and an expansion valve, etc.). The refrigerant is pressurized during delivery to ensure that it has sufficient power and pressure when it enters the sealed box. When the refrigerant flows through the field equipment in the sealed box, it absorbs the heat generated by the equipment, causing its temperature to rise. Due to the thermal expansion of the refrigerant, the internal pressure increases. This increase in pressure causes the one-way valve to open when a specific pressure threshold is reached, allowing the hot refrigerant gas to discharge. The one-way valve is designed to open only when the internal pressure is high enough to allow the refrigerant gas to discharge, and remain closed when external pressure attempts to push the valve. This design prevents the backflow of external explosive gases. The entire system continuously monitors the pressure, temperature and flow of the refrigerant through sensors to ensure that all parameters are operating within a safe range. Any abnormality will trigger a safety alarm and adjust the system parameters or stop the operation completely through automatic or manual control.

[0084] Specifically, the connection line of the heat dissipation equipment is a sealed tube body, and the inner wall of the tube body is coated with a temperature insulation coating to prevent the refrigerant from being heated by the external environment before reaching the field-side equipment. The second explosion-proof area can be surrounded by the sealed inner wall of the tube body, and the inner cavity of the tube body can allow the refrigerant to flow. And the refrigerant can wrap and protect the connection line placed inside the tube body.

[0085] As can be seen from the above, the inner wall of the tube is coated with a thermal insulation coating, which effectively prevents the refrigerant from being heated by the external environment during transportation, ensuring that the refrigerant reaches the field equipment at the optimal temperature, thereby improving the heat dissipation efficiency. The sealed tube structure provides physical isolation for the connecting lines, preventing external explosive gases or other harmful substances from contacting the lines, thereby improving the explosion-proof performance of the system. The inner cavity of the tube is designed for the flow of refrigerant. During this process, the refrigerant wraps and cools the connecting lines in the tube, effectively dissipating the heat generated by the operation of the lines. By combining thermal insulation and sealing design, the system can operate safely and efficiently in explosive environments while reducing energy losses and operation and maintenance costs.

[0086] The thermal insulation coating applied to the inner wall of the pipe body is usually made of materials with high reflectivity and low thermal conductivity, such as ceramics or special composite materials. These materials can effectively reflect thermal radiation and reduce the conduction of heat energy through the pipe wall. The sealed pipe body is usually made of high temperature and corrosion resistant materials, such as stainless steel or special plastics, to ensure durability in high temperature and chemically active environments. The sealing performance ensures that there is no refrigerant leakage and external contaminants cannot enter. The refrigerant circulates in the pipe body with the help of refrigeration system components such as compressors and expansion valves. These components control the pressure and flow rate of the refrigerant to ensure that the refrigerant flows through the pipe body in an appropriate state to maximize the heat exchange efficiency. The refrigerant absorbs the heat generated by the connecting lines in the pipe body during the flow process and releases this heat in other parts of the system (such as the condenser). This process not only ensures the appropriate operating temperature of the connecting lines, but also improves the energy efficiency of the system.

[0087] S104, mark the second explosion-proof area, the first explosion-proof area and the explosive area with gradually decreasing pressure to drive the refrigerant of the heat dissipation equipment to flow through the field-side equipment and reach the explosion-proof environment; design the energy Internet of Things through the topological network. The gradually decreasing pressure can drive the refrigerant to flow, and the one-way flow of the refrigerant can form a dynamic isolation protection to prevent the explosive gas from entering the first explosion-proof area and the second explosion-proof area.

[0088] Here, a higher pressure is set in the second explosion-proof area, which is gradually reduced to the first explosion-proof area and the explosive area. This pressure difference is used to drive the refrigerant from the heat dissipation equipment to the field-side equipment and finally reach the explosion-proof environment. The one-way flow of the refrigerant forms a dynamic isolation layer, which effectively prevents the explosive gas from reversely entering the first explosion-proof area and the second explosion-proof area with higher pressure. The refrigerant absorbs the heat generated by the field-side equipment during the flow process, reduces the operating temperature of the equipment through the heat exchange mechanism, and improves the overall stability and safety of the system. By controlling the flow and pressure of the refrigerant, the system's protection of the explosive area is strengthened, ensuring that all equipment can operate safely even under extreme conditions.

[0089] As can be seen from the above, the system controls the pressure of the refrigerant through the compressor and the pressure regulating valve. The compressor increases the pressure of the refrigerant, and the pressure regulating valve adjusts the pressure according to the needs of different areas, forming a pressure gradient that gradually decreases from the second explosion-proof area to the explosive area. The refrigerant flows in a closed circulation system and exchanges heat through the condenser and evaporator. In the condenser, heat is released to the external environment, and in the evaporator, heat generated by the field equipment is absorbed, thereby reducing the temperature of the equipment. A one-way valve is set at the key nodes of the system to ensure that the refrigerant can only flow in one direction. This design prevents the backflow of the refrigerant and the external explosive gas, and increases the safety isolation of the system. The system is equipped with pressure, temperature and flow sensors to monitor the status and environmental conditions of the refrigerant in real time. Any abnormal data will trigger an automatic adjustment or alarm system, such as automatically adjusting the pressure or shutting down a part of the system to ensure safety.

[0090] In any of the above embodiments, when the refrigerant is gas, the heat dissipation device is an automatic pressure-stabilizing air compressor and a high-pressure gas storage tank capable of natural cooling. The air compressor is connected to the high-pressure gas storage tank, and the high-pressure gas storage tank is connected to the field-end equipment through a sealed pipe body.

[0091] Air compressor will be outside the explosive area at P O Pressure and T O Fresh air at a certain temperature is compressed into air at a higher temperature and pressure. H Pressure and T H The compressed air at the temperature is then delivered to the high-pressure gas storage tank, which converts the compressed air into P H Pressure and T O Cooling air at temperature.

[0092] At this time, the heat dissipation air wraps the connection line of the interactive device in the second explosion-proof area surrounded by the sealed tube body, and extends to the field-side equipment, passes through the connection between the second explosion-proof area and the first explosion-proof area, and enters the first explosion-proof area. At this time, the heat dissipation air expansion pressure is reduced to P L And the temperature drops to T C , respectively cooling and dissipating heat, transmitting power and exchanging data for the field equipment. And the heat dissipating air becomes the temperature T H And the pressure P L of heat dissipation exhaust gas.

[0093] From the above, it can be seen that the air compressor inhales fresh air at normal temperature and pressure, increases its temperature and pressure through compression, and forms high-pressure and high-temperature compressed air, thereby driving the air to the next stage of the system. The high-pressure air tank is designed with sufficient surface area to cool the compressed air to close to the original temperature but maintain high pressure through natural cooling (i.e. ambient air or through a radiator) in preparation for the next step of use. The cooled high-pressure air flows in a sealed tube body that surrounds the connection lines of the interactive equipment and the field-side equipment, providing the necessary cooling and maintaining electrical safety. The heat dissipation air wraps the connection lines in the second explosion-proof area and cools the field-side equipment in the first explosion-proof area, while supporting the transmission of electricity and data. During the flow and cooling process of the heat dissipation air in the system, its pressure and temperature will be dynamically adjusted according to the design parameters to ensure the optimal performance of the system.

[0094] Air compressors increase the temperature and pressure of air by increasing the kinetic energy of air molecules. The heat energy from the compression process needs to be managed through the heat dissipation process of the air tank. The high-pressure air tank exchanges heat with the external environment through its large surface area, cooling the compressed air to close to the input temperature, but maintaining a high pressure state to maintain effective flow. The cooling air in the sealed tube body contacts the inner wall of the tube body and the connecting lines placed inside during the flow process, and removes the heat generated by the connecting lines through heat exchange. When the cooling air enters the first explosion-proof area, its pressure and temperature are automatically adjusted due to the changes in area and temperature. The expansion of the cooling air causes a pressure drop, which helps to provide effective cooling without increasing the risk of external explosive gas penetration. Finally, the cooled exhaust gas is discharged through the exhaust port designed by the system after heat dissipation and pressure regulation.

[0095] Furthermore, a one-way valve is located at the top of the sealed box so that the pressure P L The heat dissipation exhaust gas is discharged to the outside.

[0096] As can be seen from the above, the one-way valve allows the waste gas with increased pressure (PL) generated by the heat dissipation of the refrigerant inside the sealed box to be discharged to the outside, thereby maintaining the pressure balance and stable working environment inside the sealed box. By allowing only one-way flow of gas, the one-way valve prevents external explosive gas or other potentially harmful gas from entering the sealed box in reverse, increasing the overall safety of the system. The one-way valve automatically opens when a specific internal pressure threshold is reached, allowing excess pressure to be discharged in the form of gas, helping to prevent equipment damage or degradation of sealing performance due to excessive internal pressure.

[0097] The one-way valve is designed to open only when the internal pressure exceeds a set threshold. This design usually includes a mechanism that is either spring-loaded or gravity-dependent, ensuring that the valve remains closed at normal operating pressure and only opens automatically when the pressure reaches a level that requires exhaust. A pressure sensor is installed inside the sealed box to monitor pressure changes in real time. When the internal pressure exceeds the safety threshold, the control system sends a signal to the one-way valve, triggering it to open and discharge the pressure. During the heat dissipation process, the refrigerant absorbs heat and becomes gaseous, causing the internal pressure to increase. Since hot gases tend to rise, the one-way valve is usually set at the top of the sealed box, using the natural tendency of the gas to rise to promote the discharge of exhaust gases. The exhausted exhaust gas needs to be treated through environmental protection measures to ensure that it does not pollute the external environment. In addition, the system must ensure that there is no gas leakage during the exhaust process to maintain the sealing and safety of the system.

[0098] Specifically, the above process P H Greater than P L Greater than P O , T H Greater than T O Greater than T C .

[0099] In any of the above embodiments, when the refrigerant is coolant, the heat dissipation equipment is a water pump and a heat dissipation pool, the water pump is respectively connected to the heat dissipation shell of the field-end equipment and the cavity between the beehive and the heat dissipation pool, and the heat dissipation pool transports the coolant to the inside of the cavity through a sealed tube body.

[0100] Here, the coolant can also perform liquid-seal isolation on the connection lines of the interactive equipment and the field-side equipment. The water pump drives the coolant to circulate, and it is transported from the heat sink through the pipeline to the cavity in the heat dissipation shell of the field-side equipment, and the cooling purpose is achieved by absorbing heat. The heat dissipation shell of the field-side equipment is designed with a honeycomb cavity. This structure can increase the contact area between the coolant and the shell and improve the heat exchange efficiency. The heat sink serves as the heat energy release point of the system. After absorbing the heat generated by the field-side equipment, the coolant flows back to the heat sink, releasing heat in the process and being cooled down again. The pipe body of the entire cooling system is sealed to ensure that the coolant will not leak, while preventing external pollutants or explosive gases from entering the system, ensuring the safety and cleanliness of the operating environment.

[0101] As can be seen from the above, the water pump is a key component to promote the circulation of coolant. It is driven electrically or mechanically to force the coolant to flow, overcome the resistance and gravity in the pipeline, and ensure that the coolant can flow through the entire system. When the coolant flows through the heat dissipation housing of the field-side equipment, it absorbs the heat generated by the equipment through direct contact. The cavity of the honeycomb structure increases the surface area, making the heat exchange more efficient. The heat sink is usually located in the low temperature area of ​​the system, and the coolant may release heat through ambient air or additional cooling facilities (such as fans or water cooling systems). This process is similar to the radiator of a car, where the coolant flows in the heat sink and releases heat through the heat sink's fins or similar structures. All connecting parts of the system, including pipe joints, pumps, and heat sinks, must be well sealed to prevent coolant leakage and external contaminants from invading. In addition, the system may include a pressure relief valve or overflow device to prevent overpressure.

[0102] Specifically, the steps to design the energy Internet of Things through a topological network include:

[0103] Map explosive areas to explosion-proof environments of the Energy IoT based on working characteristics.

[0104] The field-side equipment is deployed inside the mapped explosion-prone area, and the first explosion-proof area is delineated around the field-side equipment.

[0105] Interaction equipment and heat dissipation equipment are arranged outside the explosion-prone area, and the connection lines are passed to the field-side equipment through the second explosion-proof area.

[0106] For the above specific description, the explosion-prone area is determined based on the working characteristics of the field-side equipment and the surrounding environmental conditions (such as temperature, gas type and concentration). This includes evaluating the risks that may be caused by the operation of the equipment and external environmental factors. Using geographic information systems (GIS) and risk assessment tools, the data of the explosion-prone area is combined with the needs of the IoT system for accurate geographical and environmental mapping. The field-side equipment is deployed inside the mapped explosion-prone area, and the first explosion-proof area is delineated around these equipment to ensure sufficient safety isolation. The field-side equipment is installed in key locations to collect data or control the operation process. The delineation of the first explosion-proof area is based on the specific working characteristics and potential risks of the equipment, and isolation technology and explosion-proof measures are used to ensure the safety of the internal environment. Interaction and heat dissipation equipment are deployed outside the explosion-prone area, and the second explosion-proof area is used as a safe channel to connect these equipment with the field-side equipment. Interaction equipment such as the central control system and data processing center are physically isolated from the high-risk area, while heat dissipation equipment such as cooling towers or cooling systems are set up externally according to thermal management requirements. The second explosion-proof area connects these devices through sealed and secure transmission lines to ensure safe data and energy transmission.

[0107] As can be seen above, the system adopts an integrated topological network design to optimize the equipment layout and connection mode to ensure the efficiency and security of data and energy flow. Through advanced modeling tools and simulation technology, a network architecture that can adapt to the requirements of complex environments is designed. The entire system has a built-in advanced monitoring and security system, which not only monitors the status of all key nodes in real time, but also takes immediate countermeasures when any abnormality is found, such as automatically shutting down the system or triggering an alarm. The design takes into account the maintainability of the system and the possibility of future upgrades, so that the expansion and maintenance of the system can be carried out without interfering with existing operations.

[0108] The invention provides an energy Internet of Things explosion-proof cooling integrated design method.

[0109] In any of the above embodiments, the sealed box is composed of one or more one-way exhaust valves, an electrically controllable pressure reducing expansion valve, and one or more airtight electrical connectors, at least one of which can directly lead to the pipe body, and is used to deploy the Internet of Things information data transmission line or power supply line (optical fiber + power line, or twisted pair cable) required for the energy Internet of Things. The actual types and quantities of other airtight electrical connectors can be specifically designed and configured according to the measurement and control signal connection requirements of the field equipment connected to the Internet of Things. For the energy Internet of Things that allows wireless connection, an airtight antenna connector can be further selected to install a wireless antenna of the corresponding frequency band on the sealed box to form a wireless link required for the Internet of Things information data transmission.

[0110] In this embodiment, the internal gas is automatically discharged when the internal pressure exceeds the set value to prevent the internal pressure from being too high and damaging the sealed box or affecting the operation of the equipment in the box. These valves are usually controlled by a spring-loaded mechanical device. When the internal pressure exceeds the safety pressure set by the valve, the spring pressure is overcome and the valve opens to release the gas. The gas pressure entering the sealed box is regulated to ensure that the internal pressure is maintained at the level required for safety and function. Through electric control, the opening of the expansion valve is automatically adjusted according to the pressure data monitored by the internal sensor, thereby controlling the gas flow and pressure. Provide a sealed electrical connection point for transmitting power and data signals while preventing the entry of gases and contaminants in the external environment. Use high-standard sealing technology (such as O-rings or special sealants) to ensure that the connection point will not leak under extreme conditions. Used in wireless communication equipment, it allows signal transmission while keeping the box completely sealed. Through a specially designed sealing structure, the antenna is partially exposed to receive and send wireless signals, while the connection base remains airtight to prevent gas penetration.

[0111] The above components are integrated into a highly customized sealed box, and each component is carefully designed to meet specific safety and operational requirements. The entire system works in coordination through an intelligent control unit to ensure that all components operate within safety thresholds, while monitoring the environment and internal status in real time through sensors. Electrical connectors and possible wireless antenna connectors provide the necessary data and power transmission paths. Whether wired or wireless connections, the system is designed with sufficient redundancy and protection measures to deal with risks that may arise in explosive environments. Automatic exhaust and pressure regulation mechanisms ensure that the system can protect itself and internal components when the pressure is abnormal, avoiding dangerous situations caused by environmental changes or equipment failures.

[0112] In any of the above embodiments, one or more one-way exhaust valves and an electrically controllable pressure reducing expansion valve are installed on the sealed box, and the pressure in the pipe body is P H After the compressed air passes through the electrically controllable pressure reducing expansion valve, it will form a pressure of P in the sealed box. L fresh air, relative to the air pressure P in the flammable and explosive environment outside the sealed box O Yes H >P L >P O Therefore, a slight pressure difference (ΔP = D L -P O ) automatically maintains a dynamic sealed environment to ensure that the flammable and explosive gases outside the sealed box cannot enter the sealed box, thereby realizing the micro-pressure difference dynamic sealing and explosion-proof function of the local environment sealed box.

[0113] In this embodiment, the compressed air (P H ) is accurately adjusted to a lower pressure (P L ) to ensure a stable pressure difference between the inside and outside of the box (ΔP=P L -P O ). The micro-pressure difference design ensures that the external flammable and explosive gas cannot reversely enter the sealed box, because any gas that attempts to enter will be naturally blocked by the pressure difference. When the internal pressure of the sealed box occasionally exceeds the safety threshold due to equipment operation or external temperature changes, the one-way exhaust valve will automatically open to release excess pressure and keep the internal pressure within a safe range.

[0114] When the compressed air passes through the electrically controlled pressure reducing expansion valve from the pipe, the valve adjusts the opening degree according to the instructions of the control system to accurately control the amount and pressure of gas entering the sealed box. This process relies on real-time monitoring of pressure sensor data. In the sealed box, the regulated compressed air (P L ) is maintained at a pressure higher than the external environment (P O) level, but lower than the original compressed gas pressure (P H ). This pressure level is chosen to prevent the entry of external gas by utilizing sufficient pressure difference without causing excessive pressure burden on internal equipment. The one-way exhaust valve is set at the highest point of the sealed box, and uses the natural rising characteristics of gas to promote exhaust. The valve is designed to open only when the internal pressure exceeds the set value, effectively releasing the excess pressure generated inside to the outside, avoiding potential damage to the sealed box and internal equipment due to excessive pressure. The entire system is managed by an integrated control system, which includes pressure sensors, temperature sensors and automatic control logic. The system continuously monitors the pressure difference between the inside and outside of the sealed box, and adjusts the behavior of the pressure reduction expansion valve to adapt to changes in the internal and external environments, while keeping the pressure difference within the safety threshold.

[0115] In any of the above embodiments, the sealed box is equipped with one or more one-way exhaust valves and an electrically controllable pressure reducing expansion valve, which is from the compressed air delivery pipe with a temperature of T O The compressed air, after passing through the electrically controllable pressure reducing expansion valve, will form a temperature of T at the bottom of the sealed box. C Since the airflow in the box can only flow from the pressure reducing expansion valve to the one-way exhaust valve, the cold air can conduct convection heat exchange with the distributed measurement and control node circuits of the Internet of Things when it flows through the distributed measurement and control node circuits of the Internet of Things in the box. While taking away the heat of the node circuit, its own temperature will be reduced by T C Heated to T H (T H >T O >T C ), and is finally discharged to the outside of the sealed box by a one-way exhaust valve (one or more), thereby realizing the cooling and heat dissipation function of the IoT distributed measurement and control node circuit in the box. Obviously, the temperature inside the box can be further controlled by controlling the size of the airflow.

[0116] In this embodiment, the high-temperature compressed air is decompressed and cooled to a more suitable temperature (Tc) through an electrically controllable pressure-reducing expansion valve, and then the cold air is guided to flow into the interior of the sealed box, especially to the hot spot area of ​​the IoT device. When the cold air flows through the IoT distributed measurement and control node circuit, it absorbs the heat generated by the circuit by convection heat transfer, improves the heat dissipation efficiency and prevents the equipment from overheating. After absorbing heat, the temperature of the cold air rises (TH) and is automatically discharged out of the sealed box through a one-way exhaust valve. This one-way exhaust mechanism also helps to maintain the pressure balance in the box and prevent the intrusion of external flammable and explosive gases. The system allows the temperature in the sealed box to be finely adjusted by controlling the airflow size to adapt to different operating conditions and environmental changes.

[0117] The electrically controllable pressure reducing expansion valve adjusts the pressure and temperature of the compressed air entering the sealed box as needed. The electronic control system precisely adjusts the temperature and flow of the cold air to meet the heat dissipation requirements. When the cold air flows through the IoT circuit, it absorbs the heat released by the circuit through direct contact and convection, which not only cools the circuit but also causes the temperature of the air itself to rise. When the cold air temperature rises to T H Finally, due to thermal expansion, the pressure inside the sealed box may rise and exceed the pressure outside the box. The one-way exhaust valve automatically opens when the internal pressure exceeds the set threshold, exhausting the hot air while preventing any negative impact from the external environment. The operation of the entire system is monitored by an integrated control system, which includes temperature sensors, pressure sensors and flow meters, monitors key parameters in real time, and adjusts the behavior of the pressure reduction expansion valve and exhaust valve according to preset programs or operator input.

[0118] In any of the above embodiments, the automatic pressure-stabilizing air compressor needs to be deployed in a fresh space environment that does not contain any flammable or explosive gas. Its main function is to continuously provide the entire system with a constant pressure of P without any flammable or explosive gas. H Fresh air nearby, when the air pressure in the pipe exceeds the preset P H When the air pressure in the pipe exceeds the upper limit, the air compressor will automatically stop. Conversely, when the air pressure in the pipe is lower than the lower limit, the air compressor will automatically start.

[0119] In this embodiment, the air compressor draws air from an environment without flammable or explosive gases, ensuring the purity of the inhaled air and avoiding potential safety risks. The device can automatically maintain the output air pressure at a preset P H Nearby, ensure that the air pressure in the system meets various operating requirements. When the air pressure in the system exceeds P H When the pressure exceeds the upper limit, the compressor will automatically shut down to avoid the risk of overpressure; when the pressure is lower than the lower limit, the compressor will automatically start to ensure that the pressure in the system is constant.

[0120] Air compressors usually contain one or more compression chambers that compress the air sucked in by mechanical pistons or rotating elements to increase its pressure. These mechanical elements are driven by electric motors. The compressor is equipped with pressure sensors to monitor the air pressure in the system in real time. These sensors are connected to the compressor's control system, which adjusts the compressor's operating status based on the pressure readings. The control system automatically adjusts the start and stop of the compressor based on the preset pressure threshold. If the system pressure reaches or exceeds the upper limit P H , the control system sends a signal to shut down to prevent overpressure; if the pressure is lower than P HWhen the pressure reaches the lower limit, the control system starts the compressor to supplement the pressure. The automatic control mechanism ensures that the system operates in the best safety and efficiency state. This not only prevents equipment damage or safety accidents caused by unstable pressure, but also optimizes energy consumption.

[0121] In any of the above embodiments, the natural cooling air storage tank can be the output end of the air compressor, and its main function is to temporarily store and naturally cool the compressed air. On the one hand, by temporarily storing a certain amount of compressed air, the frequent start and stop of the automatic pressure-stabilizing air compressor can be avoided. On the other hand, the compressed air stored in the air storage tank can be cooled to room temperature before being supplied to the compressed air delivery pipeline in the system through natural convection heat dissipation of the air in the surrounding environment.

[0122] In this embodiment, the air storage tank provides a buffer for the system, temporarily storing the compressed air produced by the air compressor. This can balance the demand difference between production and consumption and avoid frequent starts and stops of the compressor in response to instantaneous demand changes. The large surface area of ​​the air storage tank and the natural convection of the surrounding air allow the stored compressed air to be cooled to near ambient temperature. The temperature of the compressed air drops during the cooling process, while reducing the equipment safety risks that may be caused by high temperatures. The air storage tank extends the service life of the compressor and reduces energy consumption by reducing the frequency of starting and stopping the air compressor. Frequent starts and stops can cause mechanical wear and increase power consumption.

[0123] The air receiver acts as a buffer between the compressor and the point of use in the system. When the compressor is working, it continuously fills the air receiver with air, and when the pressure in the system reaches the preset high pressure limit, the compressor stops. When the system uses air, the pressure drops to a certain level, and the compressor starts again to keep the pressure in the system within a stable range. During the compression process, the temperature of the air will increase significantly. After the hot air is sent to the air receiver, the material and design of the tank promote the transfer of heat energy to the external environment. The air receiver is usually located in a more open or well-ventilated location to take advantage of the flow of ambient air to carry away heat. As the temperature of the stored air decreases, the density of the air increases, which means that more air can be stored in the same volume. The cooled air requires less cooling of the system when it is used, improving the performance and efficiency of air tools and equipment.

[0124] In any of the above embodiments, the sealed box, the automatic pressure-stabilizing air compressor and the natural cooling air storage tank have the main function of providing a completely enclosed compressed air delivery channel and a hidden channel for the Internet of Things line for the entire system, thereby achieving safe, clean and tidy compressed air gas line connection and Internet of Things line connection.

[0125] In this embodiment, the sealed box provides physical protection for sensitive electronic components of the Internet of Things from external environmental factors such as dust, moisture, chemical corrosion or explosive gases. It is usually made of solid metal or other non-conductive materials, and may be coated with anti-static materials inside to ensure the safety of electronic equipment. The automatic pressure-stabilizing air compressor provides compressed air with constant pressure for various operations and tools, especially in environments where a clean and stable air source is required. The air pressure is monitored by an automatic control system, and it automatically starts and stops when the pressure exceeds or falls below the set range to keep the system pressure stable. The natural cooling air tank stores a large amount of compressed air, exchanges heat with the ambient air through its surface, achieves natural cooling, reduces the air temperature, and improves storage efficiency. The air tank is designed with a large-area shell, which uses natural convection and radiation heat dissipation to cool the stored compressed air to approximately ambient temperature. The fully enclosed delivery channel safely delivers compressed air and hides the Internet of Things communication lines to avoid any external contamination or interference. Use sealed pipes and special cable management systems to ensure that all connections are airtight and waterproof.

[0126] The system is managed by an integrated control unit, which includes pressure sensors, temperature monitoring, and automated control software. These control units can adjust the operating status of the compressor in real time, monitor the pressure and temperature of the gas tank, and maintain the stability of the environment inside the sealed box. Sensors in the system continuously monitor key parameters such as pressure, temperature, and flow. Any reading that deviates from the preset operating range will trigger automatic adjustments, such as starting or stopping the compressor, adjusting the opening of the pressure reducing expansion valve, or enabling additional cooling measures. All system components are designed with safety backup and emergency response mechanisms, such as overpressure protection, explosion-proof design, and emergency shutdown function. This ensures that the safety of the system and personnel will not be threatened under extreme or unforeseen operating conditions.

[0127] In any of the above embodiments, the Internet of Things information data transmission line or power supply line is mainly used for information data transmission in the energy Internet of Things and self-powering of micro-power information equipment. Its main function and technical feature is that only one cable is needed to realize all information data transmission and self-powering of micro-power information equipment in the energy Internet of Things.

[0128] In this embodiment, the cable design includes sufficient data line pairs (which may be twisted pair or optical fiber) for high-speed and efficient data communication. This allows seamless information exchange between control centers, sensors, actuators and other devices in the Energy Internet of Things. The cable contains dedicated power conductors to supply the power required by micro-power devices such as sensors, small controllers, etc. These devices generally do not require high power, so powering through the same cable can simplify the system design. The design of combining data and power reduces the number of cables in the overall system, thereby reducing the complexity of the system and the installation cost. In addition, this design also helps to optimize space utilization and reduce maintenance difficulties.

[0129] In the same cable, data signals (which may be digital or optical signals) and power can be transmitted in parallel, but signal interference must be minimized. Shielding and isolation technology is used in cable design to effectively separate power and data lines to ensure the clarity and accuracy of data transmission. The power line in the cable is designed to be low-voltage DC power supply, suitable for micro-power devices. The system may include voltage regulators and current management modules to ensure that each device connected to the cable can receive stable and safe power. Since the cable transmits power and data at the same time, it must have an effective thermal management system to prevent overheating from affecting cable performance and safety. In addition, it is also necessary to integrate overload protection and circuit breaker protection mechanisms to prevent circuit short circuits or power overloads.

[0130] In any of the above embodiments, a cable that can be hidden in the compressed air delivery pipe includes but is not limited to an Internet of Things information data transmission line, which can be a twisted pair cable that can be used for both information data transmission and information equipment power supply, or it can be just an optical fiber, or a composite cable including an optical fiber + power supply line, wherein the power supply line can solve the power supply problem of most of the Internet of Things measurement and control node circuits in the local environment sealed box, including but not limited to. Except for individual high-power Internet of Things measurement and control node circuits that need to be powered separately through other airtight electrical connectors, other circuits (including measurement and control nodes required by the Internet of Things system, network photoelectric converters, network switches or routers, etc.) can obtain the power required for their work through this cable that can be hidden in the compressed air delivery pipe.

[0131] In this embodiment, the cable may include a high-performance twisted pair or optical fiber for transmitting data between IoT devices. Such data include, but are not limited to, sensor data, control signals, and real-time monitoring video. The power cord in the cable is used to power the IoT measurement and control node circuit. These nodes typically require low to medium power and are suitable for powering via an integrated power cord. The composite cable combines optical fiber and power cord to meet the needs of high-speed data transmission and power supply. This design reduces the number of cables in the system and simplifies installation and maintenance. Hiding the cables in the compressed air delivery pipe not only protects the cables from physical damage and environmental impacts, but also increases the aesthetics of the system and the confidentiality of the lines.

[0132] The cables are arranged in the compressed air delivery pipe to transmit data and power at the same time. This design makes full use of the existing pipeline facilities, reduces the need for additional cable pipelines, and effectively saves space and cost. Shielding and isolation technology is used to reduce the interference of power transmission on data signals. In the case of twisted pair cables, electromagnetic interference is reduced by differential signal transmission; in the case of optical fiber, since the signal is transmitted by light, it is not affected by electromagnetic interference. When deploying cables in pipelines that transport compressed air, it is necessary to ensure that the insulation and heat resistance of the cables meet the requirements. Use high-quality insulation materials and appropriate heat dissipation measures to ensure the stable operation of the cables in various environments. The power cord design meets the power requirements of most IoT devices. For devices with higher power requirements, separate power supply is provided through other airtight electrical connectors to ensure the stability and safety of the power supply of the entire system.

[0133] The embodiment of the second aspect of the present invention proposes an energy Internet of Things designed by an energy Internet of Things explosion-proof cooling integrated design method. In some embodiments of the present invention, such as Figure 2 As shown, the energy Internet of Things includes field-side equipment and interactive equipment and heat dissipation equipment connected to the field-side equipment;

[0134] Interactive equipment, heat dissipation equipment and field equipment all adopt non-explosion-proof design.

[0135] In the energy Internet of Things provided by the present invention, the field-side equipment is directly deployed at the operation site, and may include sensors, actuators, and data acquisition units, etc., for monitoring and controlling the production process. Interactive equipment: including equipment for control and data processing, such as PLC (programmable logic controller), industrial PC or other intelligent control systems, which are responsible for processing the data collected by the field-side equipment and making control decisions. Heat dissipation equipment is used to maintain all equipment, especially computing-intensive interactive equipment, working within a safe temperature range, and may include fans, cooling towers or other cooling systems.

[0136] Even if the equipment itself is non-explosion-proof, the system ensures overall safety through an integrated explosion-proof cooling strategy. For example, an explosion-proof isolation shell can be designed around the equipment, or pressure and gas monitoring technology can be used inside the system to prevent the accumulation of explosive gases and potential explosion risks. Integrated heat dissipation equipment ensures that all key equipment, especially interactive equipment that generates more heat, is maintained at the optimal operating temperature. Through effective heat dissipation design, such as by adding a radiator or using a coolant circulation system, the safety and stability of the system can be indirectly improved. Although the equipment itself is non-explosion-proof, the system ensures the safety of the operating environment by real-time monitoring of environmental factors that may cause explosions (such as temperature, pressure, and gas concentration). In addition, the system may also include an automatic emergency response mechanism, such as automatically shutting down the system when excessive concentrations of dangerous gases are detected. With physical isolation, enhanced ventilation systems, and strict environmental controls, even non-explosion-proof equipment can operate safely in potentially dangerous environments. In addition, all electrical connections and power management systems are designed with sufficient safety protection measures, such as overcurrent protection and fire prevention design.

Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
