This represents the corresponding single-event power consumption quota, in kilowatt-hours per event (kWh / r); S represents the number of high-definition broadcast sports events at the stadium per year, in events (r).

[0010] Preferably, as described above, the user interaction and visualization module provides a web- or mobile application-based user interface that supports data visualization.

[0011] Preferably, as described above, the data acquisition and monitoring module collects energy consumption data and environmental parameters in real time through smart sensors widely deployed in various areas. The data is then transmitted to the data acquisition and monitoring module for preprocessing and encryption using Internet of Things (IoT) technology.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention provides a blockchain-based smart energy management system suitable for large sports centers. Utilizing blockchain technology, data is encrypted and distributed across multiple nodes, ensuring its immutability and tamper-proof nature, guaranteeing the authenticity and integrity of energy data. Simultaneously, digital signatures and authentication mechanisms effectively prevent unauthorized access, further enhancing data security. The decentralized nature of blockchain eliminates traditional multi-level approval processes; smart contracts can automatically execute energy transactions according to preset rules, accelerating the transaction process and reducing human intervention, thus significantly improving the efficiency and flexibility of energy management. Through big data analysis of energy consumption patterns, combined with the sports center's activity schedule and environmental parameters, smart contracts can achieve rational energy allocation and scheduling. For example, on match days, priority is given to ensuring energy supply to the competition venues, while automatically adjusting energy use in other areas to ensure efficient energy utilization. Sensors collect energy consumption and environmental data in real time; after blockchain verification, managers can immediately access and analyze this data. This real-time monitoring mechanism can quickly locate problems, such as equipment malfunctions or energy waste, allowing for timely measures to optimize energy use.

[0021] The following examples further illustrate the features of the present invention and other related features in detail, so as to facilitate understanding by those skilled in the art.

[0022] In this embodiment, it should be understood that the terms "middle," "upper," "lower," "top," "right side," "left end," "above," "back," "center," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0023] like Figures 1 to 4 As shown, a blockchain-based smart energy management system suitable for large sports centers includes the following core components: a blockchain network layer, a security module, a data acquisition and monitoring module, a user interaction and visualization interface, and an energy management and analysis module.

[0024] The data acquisition and monitoring module collects energy consumption data and environmental parameters in real time through smart sensors widely deployed in various areas. This data is transmitted to the data acquisition and monitoring module via IoT technology for preprocessing and encryption. The encrypted data is then broadcast and verified through a blockchain network, and packaged into the blockchain through a consensus mechanism to ensure data security, transparency, and immutability. The energy management and analysis module uses big data analytics to model and predict energy usage patterns. Based on the sports center's activity schedule and environmental conditions, it uses smart contracts to optimize energy allocation and automate transactions. The user interface and visualization present energy information in real time, facilitating strategy adjustments by management personnel. The entire system operates stably under a security guarantee mechanism, achieving efficient energy utilization and refined energy management.

[0025] Preferably, as described above, a decentralized blockchain network will be constructed, connecting various energy nodes within the sports center (such as electrical equipment, water treatment systems, and air conditioning systems) as nodes on the blockchain. Each node can record its own energy consumption information, equipment status information, etc., in real time and broadcast this information to the blockchain network in the form of transactions. The blockchain network uses a consensus mechanism (such as PBET, PoS, or DPoS) to ensure the authenticity and immutability of information. (DPoS consensus time is less than 2 seconds, enabling real-time scheduling during events. PoS is suitable for small-scale training grounds, achieving cost control while ensuring energy conservation. PBET has strong resistance to malicious nodes and is suitable for international sports venues with extremely high security requirements.) Preferably, as described above, the data acquisition and monitoring module will deploy a smart sensor network in various functional areas of the sports center to collect real-time energy consumption data, equipment operating status data, and environmental parameters (such as temperature, humidity, and light intensity). The collected data will then be transmitted to the blockchain network layer via Internet of Things (IoT) technology to ensure the real-time nature and accuracy of the data. The data acquisition module supports multiple communication protocols (such as ZigBee, LoRa, and NB-IoT) to adapt to the communication needs of different devices.

[0026] Preferably, this invention introduces data redundancy and fault tolerance mechanisms in the data acquisition and monitoring module to ensure that energy data can still be reliably recorded and recovered in the event of network fluctuations or node failures. Specifically, the system achieves dual data protection through multi-node redundant storage and edge caching: energy data is written to backup nodes while being uploaded to the main node, and the backup nodes take over when the main node fails, preventing data loss; each regional gateway node has local caching capabilities, which can temporarily store data in the event of a network outage and automatically synchronize it to the blockchain network after the network is restored, thereby ensuring data integrity. Simultaneously, the system supports multiple communication protocols and can automatically switch to a backup link when a communication link fails, ensuring the continuity of data transmission. Through majority node verification and anomaly alarm mechanisms, this invention further enhances the fault tolerance of data and the reliability of operation, ensuring the stability and security of energy management in the sports center during major events.

[0027] Preferably, as described above, the energy management and analysis module uses big data analytics to model and predict energy consumption patterns based on historical and real-time data from the blockchain network. Then, it optimizes the energy allocation scheme according to the sports center's activity schedule (such as competition schedules, commercial activities, etc.) and environmental parameters to achieve rational energy scheduling.

[0028] Preferably, the energy management and analysis module of the present invention employs a combination of multiple analysis methods when modeling and predicting energy consumption patterns, including but not limited to: time series analysis methods (such as ARIMA and LSTM neural networks) for predicting load changes at different times; clustering analysis methods (such as K-means and hierarchical clustering) for identifying typical energy consumption characteristics of different functional areas; optimization scheduling algorithms (such as linear programming, nonlinear programming, and genetic algorithms) for achieving the optimal energy allocation scheme while meeting the needs of the event and environmental constraints; and anomaly detection algorithms (such as threshold detection based on statistics or isolated forest models based on machine learning) for timely detection of equipment anomalies or energy waste. Through the comprehensive application of the above analysis methods, the present invention can achieve accurate energy demand prediction and dynamic scheduling during the event, thereby improving energy utilization efficiency and reducing operating costs.

[0029] Preferably, the user interaction and visualization interface described above provides a web-based or mobile application-based user interface for use by sports center managers, venue operators, and equipment maintenance personnel. The interface displays real-time information such as energy consumption, equipment status, and energy transaction records, and supports data visualization (e.g., charts, maps). Users can set energy management strategies and alarm thresholds through the interface to achieve remote monitoring and management.

[0030] Preferably, the user interaction and visualization module of this invention sets up a hierarchical permission management mechanism, assigning different access and operation permissions according to different user roles to ensure system security and refined management. Specifically, the system divides users into three categories: administrators, maintenance personnel, and supervisors. Administrators have the highest permissions, allowing them to view all energy data, formulate energy management strategies, set smart contract rules, and adjust alarm thresholds. Maintenance personnel are primarily responsible for equipment status monitoring and fault handling, and have the permission to view and submit maintenance data, but cannot modify global energy strategies. Supervisors have only read-only permissions, allowing them to view energy consumption, transaction records, and system operation logs in real time for auditing and compliance supervision. Through this hierarchical permission mechanism, this invention can prevent unauthorized operations, improve system security and reliability, and simultaneously meet the actual needs of different roles in energy management.

[0031] Preferably, the security module employs multi-layered encryption technologies (such as AES, RSA, etc.) to encrypt data in the blockchain network, ensuring the security of data transmission and storage. Digital signature technology verifies the integrity and origin of data, preventing data tampering. Firewalls, intrusion detection systems, and other network security technologies protect the blockchain network from external attacks.

[0032] Furthermore, energy consumption calculations for sports venues need to cover multiple energy forms such as electricity, heat, and diesel. For large sports centers, the optimal energy management solution should follow these steps: A smart sensor network is deployed in various functional areas of the sports center to collect real-time data on energy consumption, equipment operating status, and environmental parameters (such as temperature, humidity, and light intensity). The data acquisition module supports multiple communication protocols (such as ZigBee, LoRa, and NB-IoT) to adapt to the communication needs of different devices.

[0033] Furthermore, the collected data undergoes preprocessing, including data cleaning and format conversion, to ensure data accuracy and consistency.

[0034] Furthermore, the preprocessed data is encrypted using encryption algorithms such as AES and RSA to ensure data security during transmission. The encrypted data is then transmitted to the blockchain network layer via Internet of Things (IoT) technology.

[0035] Furthermore, the encrypted data is broadcast and verified via the blockchain network, and packaged into the blockchain through consensus mechanisms (such as PBET, PoS, or DPoS) to ensure that the data is secure, transparent, and tamper-proof.

[0036] Furthermore, energy consumption calculations are performed on the data stored on the blockchain based on the calculation formula in the "Energy Consumption Quota for Sports Venues". For example, the electricity consumption per match (e.g., a football game / large-scale cultural performance) can be calculated using the following formula:

[0037] in, This indicates the power consumption per match for a high-definition broadcast of a football match (or a football match broadcast on a color TV, a football match without broadcasting, or a large-scale cultural performance), expressed in kilowatt-hours per match (kWh / r). The unit represents the corresponding single-game power consumption quota, in kilowatt-hours per game (kWh / r); S represents the number of high-definition broadcast football matches (or color TV broadcast football matches, non-broadcast football matches, large-scale cultural performances) per year in a football stadium, in games (r).

[0038] Furthermore, based on historical and real-time data from the blockchain network, big data analytics are used to model and predict energy consumption patterns. Combined with the sports center's activity schedules (such as match schedules and commercial activities) and environmental parameters, energy allocation schemes are optimized to achieve rational energy scheduling.

[0039] Furthermore, smart contract technology can be used to automatically execute energy transactions according to preset rules. For example, on match days, priority can be given to ensuring the energy supply to the match venues, while energy use in other areas can be automatically adjusted to ensure efficient energy utilization.

[0040] Furthermore, sensors collect energy consumption and environmental data in real time, which, after being verified by blockchain, can be immediately accessed and analyzed by managers. This real-time monitoring mechanism can quickly pinpoint problems, such as equipment malfunctions or energy waste, so that timely measures can be taken to optimize energy use.

[0041] Furthermore, through a web-based or mobile application-based user interface, information such as energy consumption, equipment status, and energy transaction records can be displayed in real time, and data visualization (such as charts and maps) is supported. Users can set energy management strategies and alarm thresholds through the interface to achieve remote monitoring and management.

[0042] Construction of the blockchain network layer: Choose a suitable blockchain protocol (such as Ethereum, Hyperledger Fabric, etc.) to build a decentralized blockchain network. Register all energy-related equipment within the sports center (such as smart meters, water meters, air conditioning controllers, etc.) as blockchain nodes. Design a consensus algorithm (such as DPoS) to ensure efficient network operation and data security. Each node periodically collects its own energy consumption data, encrypts it, and broadcasts it to the blockchain network as a transaction. Other nodes verify the transactions and package them into blocks through the consensus mechanism.

[0043] Deployment of the data acquisition and monitoring module: A smart sensor network, including temperature, humidity, and light sensors, is deployed in different areas of the sports center. The LoRa protocol is used to transmit the data collected by the sensors to gateway nodes in the blockchain network layer. The gateway nodes perform preliminary processing on the received data (such as data cleaning and format conversion) and then send the processed data to the blockchain network. Edge computing technology is used on the gateway nodes to perform real-time analysis of some data, such as real-time monitoring of abnormal equipment status.

[0044] Implementation of the energy management and analysis module: Historical and real-time energy data are retrieved from blockchain networks and stored on big data platforms (such as Hadoop and Spark). Energy consumption patterns are analyzed and predicted using machine learning algorithms (such as linear regression and cluster analysis). Energy allocation plans are developed based on the sports center's activity schedule and environmental parameters. For example, energy supply to the competition venues is increased on match days while energy consumption in other areas is appropriately reduced. Smart contracts are designed to enable energy trading. For instance, when energy supply in one area is insufficient, surplus energy can be automatically purchased from other areas via smart contracts.

[0045] User interaction and visual interface design: Develop a web-based user interface that supports multiple browsers (such as Chrome, Firefox, etc.).

[0046] The interface is designed with a real-time data monitoring module to display energy consumption curves and equipment status icons for each area.

[0047] It provides data visualization capabilities, such as displaying the energy consumption distribution in different areas of the sports center via a map. Users can set energy management strategies through the interface, such as setting temperature and humidity thresholds; when these thresholds are exceeded, alarms are automatically triggered or equipment operating status is adjusted.

[0048] Configuration of the security module: Data in the blockchain network is encrypted using the AES encryption algorithm to ensure data security during transmission and storage. RSA digital signature technology is used to verify the data source and prevent data tampering. Firewalls and intrusion detection systems are deployed at the blockchain network boundary to prevent external attacks.

[0049] The following examples further illustrate the features of the present invention and other related features in detail, so as to facilitate understanding by those skilled in the art.

[0050] like Figure 1 As shown, the smart energy management system of the present invention includes a blockchain network layer 1, a security module 2, a data acquisition and monitoring module 3, a user interaction and visualization interface 4, and an energy management and analysis module 5.

[0051] like Figure 2As shown, the data acquisition and monitoring module 3 collects energy consumption data and environmental parameters in real time through smart sensors widely deployed in various areas. The collected data includes, but is not limited to, electricity consumption, water consumption, gas consumption, temperature, humidity, and light intensity. This data is transmitted to the data acquisition and monitoring module 3 via IoT technology for preprocessing and encryption. The encrypted data is broadcast and verified through a blockchain network, and packaged into the blockchain through a consensus mechanism to ensure data security, transparency, and immutability.

[0052] like Figure 3 As shown, the Energy Management and Analysis Module 5 utilizes big data analytics to model and predict energy usage patterns. Based on the sports center's event schedule and environmental conditions, it leverages smart contracts to optimize energy allocation and automate transactions. For example, the system can adjust energy allocation plans in advance based on the match schedule to ensure sufficient energy supply to the venues during matches, while reducing unnecessary energy consumption in other areas.

[0053] like Figure 4 As shown, the user interaction and visualization interface 4 provides a web-based or mobile application-based user interface for use by sports center managers, venue operators, and equipment maintenance personnel. The interface displays real-time information such as energy consumption, equipment status, and energy transaction records, and supports data visualization (e.g., charts, maps). Users can set energy management strategies and alarm thresholds through the interface to achieve remote monitoring and management.

[0054] The above are merely typical embodiments of the present invention. In addition, the present invention may have many other specific implementations.
