Description

Technical Field

[0001] The present invention relates to the field of energy monitoring technology of Internet of Things technology, and more specifically, to a park energy monitoring method and system based on Internet of Things. Background Art

[0002] With the development of the global economy and the acceleration of urbanization, the scale and complexity of industrial parks, as an important area of ​​concentrated economic activities, are constantly increasing, and energy consumption is also growing. In this context, it is crucial to effectively monitor and manage industrial park energy.

[0003] The traditional park energy management method mainly relies on manual inspections and simple metering equipment, which has many limitations. In terms of data collection, manual collection is inefficient and accuracy is difficult to guarantee, and real-time and continuous data acquisition cannot be achieved, resulting in a lack of timely and accurate data support for energy management decisions. Data transmission mostly adopts wired methods, which have high wiring costs and poor flexibility, and are easily disturbed during transmission, resulting in low data security. For data analysis, traditional methods are mainly based on experience and simple statistics, making it difficult to deeply explore the potential value in energy data, and unable to accurately predict and analyze energy consumption trends, equipment operating status, etc., and difficult to discover potential energy waste and equipment failure hazards. In terms of energy distribution, there is a lack of scientific path planning, resulting in increased distribution costs and low efficiency. At the same time, traditional systems have deficiencies in collecting and utilizing user feedback, and cannot optimize energy distribution strategies based on actual user experience, resulting in low user satisfaction. In addition, data security measures are weak, energy monitoring data is easy to be tampered with, and has low credibility. In addition, data sharing and interaction are difficult, which cannot meet the needs of multi-department collaboration in park energy management.

[0045] Figure 2 This is a step-by-step diagram of a campus energy monitoring method based on the Internet of Things. DETAILED DESCRIPTION

[0046] The drawings are for illustrative purposes only and should not be construed as limiting the present patent;

[0047] In order to better illustrate the present embodiment, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product;

[0048] It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0049] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0050] Example 1

[0051] The IoT-based park energy monitoring system of this embodiment is deployed in a modern industrial park covering an area of ​​about 10 square kilometers. There are many manufacturing companies, office buildings, data centers and supporting public facilities in the park. The energy consumption types are mainly electricity, natural gas and heat. The energy supply sources include a 110kV substation, two gas boiler rooms and several distributed solar photovoltaic power generation devices. The park network infrastructure is complete, achieving full coverage of wired Ethernet and wireless networks (Wi-Fi and 5G signals), ensuring the data transmission needs of IoT devices.

[0052] A campus energy monitoring system based on the Internet of Things, such as Figure 1 As shown, including:

[0053] The path planning module builds an energy distribution network model, uses the ant colony algorithm to determine the optimal distribution path, and dynamically adjusts the distribution path selection probability;

[0054] VR / AR interface module, which creates a 3D model of energy facilities, integrates real-time energy facility monitoring data with the 3D model for display, and enables user interactive energy monitoring and control;

[0055] Visual image module, monitors the operating status of energy facilities, analyzes energy efficiency, and warns of abnormal situations;

[0056] Affective computing module, which collects and analyzes user feedback and adjusts energy allocation strategies;

[0057] The blockchain module encrypts and stores energy facility monitoring data to ensure that the data cannot be tampered with.

[0058] The path planning module further comprises:

[0059] The network model building unit is used to build an energy distribution network model, including investigating the energy supply sources and consumption nodes in the park, and assigning attribute information to each edge;

[0060] The park's energy management team works closely with the energy managers of each enterprise to conduct in-depth research on the park's energy supply sources and consumption nodes. For substations, their geographical locations, transformer capacities, output voltage levels, and power supply ranges are recorded in detail. For gas boiler rooms, information such as gas supply pressure, boiler thermal power, and heating areas are accurately mastered. For each enterprise and public facility, comprehensive statistics are collected on electricity, gas, and heat consumption data at different times, peak and average energy consumption are estimated, and their location distribution within the park is clearly defined.

[0061] Combined with the park's geographic information system (GIS) data, supply sources such as substations and boiler rooms and consumption points are regarded as network nodes, and roads and underground pipelines are used as connecting edges to construct an energy distribution network model. Attributes are assigned to the edges of the power distribution path. For example, the transmission loss coefficient is determined based on the resistance value calculated based on the cable material and length, and the rated transmission capacity is set based on the cable specifications. For the gas pipeline edge, the transmission loss coefficient related to the friction coefficient is calculated considering the pipeline material and diameter, as well as attribute information such as the design flow upper limit.

[0062] A path optimization unit, used to determine the optimal energy distribution path through the ant colony algorithm, including initializing algorithm parameters and calculating the total cost of the distribution path;

[0063] Initialize the parameters of the ant colony algorithm, set the number of ants to 50, the pheromone volatility coefficient to 0.3, the pheromone heuristic factor to 2, and the expected heuristic factor to 1. Based on the energy distribution network model provided by the network model construction unit, start the ant colony algorithm to simulate the foraging behavior of ants to select paths. In the iterative process, calculate the total cost of each distribution path, and comprehensively consider factors such as path length (the actual geographical distance between nodes is calculated by the GIS system), transmission loss (calculated based on the transmission loss coefficient of the edge and the expected transmission energy), and construction and maintenance costs (estimated with reference to the historical construction and maintenance cost data of the park). For example, for the path of distributing electricity to a large manufacturing enterprise, a path with a shorter geographical distance but a larger transmission loss due to aging of some cables may be initially selected. With iterative optimization, a better path is gradually found after comprehensively considering the loss and cost. After 100 iterations, the optimal energy distribution path is determined.

[0064] The pheromone updating unit is used to adjust the pheromone concentration according to the optimal delivery path information, simulate the pheromone volatilization process, and dynamically adjust the pheromone volatilization speed and increase amount.

[0065] After the path optimization unit determines the optimal delivery path, it increases the pheromone concentration on the path according to specific rules. For example, the increase in pheromone concentration is proportional to the degree of advantage of the total cost of the path (the lower the total cost, the greater the increase). At the same time, it simulates the pheromone volatilization process and, according to the set volatilization coefficient, multiplies the pheromone concentration on other paths by (1-volatility coefficient) for attenuation after each iteration.

[0066] Real-time monitoring of the distribution path network status, such as obtaining information such as power line load changes and gas pipeline pressure fluctuations through sensors. When a sudden increase in energy demand in a certain area is found, such as an increase in electricity demand caused by an enterprise's expansion of production, the pheromone volatilization rate on the relevant paths in the area is appropriately increased to encourage ants to explore new paths faster. When the overall energy distribution system is in a stable low-load state, the pheromone volatilization rate is appropriately reduced to facilitate ants to conduct detailed searches near the found better paths. For example, the business volume of a data center in the park suddenly increases. The pheromone update unit speeds up the volatilization rate of pheromones on the path leading to the substation in the area, guiding the ant colony to re-evaluate the path selection, and ultimately optimize the distribution path to ensure a stable and efficient energy supply for the data center.

[0067] The VR / AR interface module further includes:

[0068] A three-dimensional model building unit, which uses laser scanning technology and drone aerial photography to obtain the geometric shape and spatial location information of energy facilities and generate a three-dimensional model;

[0069] Use high-precision laser scanning equipment to conduct all-round scanning of large energy facilities such as substations and gas boiler rooms, obtain geometric shape and spatial position information accurate to the millimeter level, generate detailed point cloud data, and use drones equipped with high-definition cameras to conduct multi-angle aerial photography for distributed solar photovoltaic power generation devices that are widely distributed and complex in structure. After obtaining the image data, combine it with professional 3D reconstruction algorithms to convert it into 3D model data.

[0070] The three-dimensional model data is deeply associated and bound with the attribute information of the energy facilities. In the three-dimensional model of the substation, key information such as the model, rated capacity, production date, and last maintenance time of each transformer is marked in detail; in the gas boiler room model, parameters such as the boiler's thermal efficiency, gas consumption rate, and safety valve set pressure are accurately recorded; for photovoltaic power generation devices, data such as the photovoltaic panel's photoelectric conversion efficiency, inverter model and efficiency are noted, making it convenient for users to quickly query and understand the details of the equipment during the interaction process.

[0071] The data fusion display unit is used to deploy Internet of Things sensor nodes to collect operating data of energy facilities and map real-time energy facility monitoring data onto the three-dimensional model.

[0072] IoT sensor nodes are deployed at the energy supply sources, main energy consumption areas and key equipment nodes in the park. High-precision current and voltage sensors, as well as temperature sensors for monitoring transformer oil temperature and winding temperature are installed in each switch cabinet of the substation. Gas flow sensors, steam pressure sensors, flue gas composition sensors, etc. are installed in the gas boiler room. Smart meters are installed in the power distribution rooms of each enterprise and the distribution boxes of public facilities, heat meters are installed on the heating pipes, and temperature and humidity sensors are installed in the air-conditioning system to collect operating data of energy facilities.

[0073] The data collected by the sensors are transmitted to the data fusion display unit in real time via Wi-Fi or 5G networks. An intelligent data mapping algorithm has been developed to accurately map the real-time data to the corresponding positions and objects in the three-dimensional model based on the correspondence between the sensor data type and the equipment and areas in the three-dimensional model. For example, in the three-dimensional model of the substation, the load condition of the transformer is intuitively displayed through color changes, with green indicating normal load, yellow indicating slight overload, and red indicating severe overload. The curves of voltage and current changes over time are also presented in the form of dynamic charts. In the gas boiler room model, parameters such as gas flow and steam pressure are displayed with real-time updated values, and the working status of the burner is displayed with animation effects.

[0074] Different update cycles are set according to the frequency of change and importance of sensor data. For data that changes quickly and has a greater impact on energy management decisions, such as power load and gas flow, it is updated every 5 seconds; for data that changes relatively slowly, such as temperature and pressure, it is updated every 30 seconds to ensure the timeliness and accuracy of the data.

[0075] The visual image module further comprises:

[0076] Camera deployment unit, used to select camera sites and plan layouts based on energy facility distribution and monitoring priorities;

[0077] Camera site selection and layout planning are carried out based on the distribution of energy facilities in the park and monitoring priorities. Multiple high-definition surveillance cameras are installed around the substation at different angles and distances to ensure full coverage of key equipment such as transformers, switch cabinets, busbars, etc., to monitor their operating status and potential safety hazards without blind spots, such as whether there are abnormal phenomena such as smoke, discharge, oil spraying, and whether personnel are operating in violation of regulations.

[0078] Inside the gas boiler room, high-definition cameras with explosion-proof functions are installed at key locations such as the boiler body, burner, gas pipelines, valves, etc. to monitor equipment operation in real time and detect gas leaks in a timely manner, such as by observing whether there are abnormal phenomena such as smoke and fog at the pipeline connections, and flame abnormalities, such as abnormal flame color and unstable combustion. Cameras are installed at the external entrances and exits of the boiler room and surrounding areas to monitor the entry and exit of personnel and the transportation of materials to prevent unauthorized personnel from entering dangerous areas.

[0079] For distributed photovoltaic power stations, panoramic cameras and high-definition cameras with automatic zoom are installed in the photovoltaic panel array area to monitor the surface condition of the photovoltaic panels, whether there are obstructions such as dust, snow, bird droppings, whether the photovoltaic panels are damaged or deformed, the operating status of the inverter, whether there are any abnormalities such as overheating and alarm lights, as well as the surrounding environment, such as whether there are trees growing that affect light.

[0080] For substations and boiler rooms, low-illumination, high-resolution cameras, such as 4K and above, with automatic zoom and focus functions and wide dynamic range, are selected to adapt to environments with dim light and the need to clearly observe equipment details, while being able to accurately capture image details in conditions of strong light and shadow contrast. For outdoor photovoltaic power stations, cameras with waterproof and dustproof functions, wide temperature range and high reliability are selected, which can work stably under severe weather conditions such as high temperature, heavy rain, wind and sand.

[0081] Establish a camera network management system to realize centralized management and remote control of all cameras. Through the network management system, administrators can remotely adjust camera parameters, such as resolution, and switch between different scenarios according to actual monitoring needs. For example, use lower resolution to save network bandwidth during normal monitoring, and switch to high resolution for detailed observation when abnormal conditions are found, frame rate, increase frame rate when events are triggered to obtain clearer dynamic images, exposure time, automatically adjust according to light changes to ensure image clarity, etc.; formulate flexible image acquisition plans, support scheduled acquisition, such as taking a group of images at regular intervals for daily inspection records, event-triggered acquisition, such as automatically starting to continuously acquire images and videos when the camera detects moving objects or specific abnormal conditions; optimize data transmission management, adopt data caching and breakpoint-resume transmission technology to ensure that image and video data are stably and efficiently transmitted to the image processing server under network fluctuations; monitor the camera status in real time. When the camera fails, such as disconnection, image blur, equipment hardware failure, etc., the system immediately issues an alarm to notify the administrator, and records the fault information and time for timely maintenance.

[0082] An image recognition unit, which is used to identify key equipment and components in energy facilities using object detection algorithms and extract equipment operating parameters using feature extraction algorithms;

[0083] Advanced target detection algorithms based on deep learning, such as the improved YOLOv5 algorithm, are used to process images and video data collected by the camera in real time to identify various key equipment and components in energy facilities. In substations, it can accurately identify transformers, circuit breakers, mutual inductors, lightning arresters, capacitors and other equipment, and accurately locate their positions in the image; in gas boiler rooms, it can identify boiler bodies, burners, fans, water pumps, various valves, instruments and other components; in photovoltaic power stations, it can identify photovoltaic panels, inverters, combiner boxes, tracking brackets and other equipment.

[0084] For the identified equipment and components, feature extraction algorithms are used, such as combining the advantages of scale-invariant feature transform (SIFT) and speeded up robust feature (SURF) algorithms to extract their key feature information. For example, the appearance shape and texture features of the transformer are used to determine whether it is deformed or leaking oil; the color, shape, and brightness distribution characteristics of the burner flame are used to analyze the combustion efficiency and stability; the surface color and texture uniformity characteristics of the photovoltaic panel are used to detect whether there are obstructions or damage. Combined with the equipment operation principle and related knowledge, the operating parameters of the equipment are calculated by analyzing the changes in feature information. For example, the transformer oil temperature rise rate is calculated by monitoring the changes in the surface temperature characteristics of the transformer oil tank, and the heat dissipation performance of the transformer is evaluated in combination with the load current data; the mixing ratio of gas and air is calculated based on the burner flame characteristics, and then the combustion efficiency is determined; the trend of the power generation efficiency of the photovoltaic panel is calculated by analyzing the changes in the reflected light characteristics on the surface of the photovoltaic panel, so as to promptly discover inefficient links and potential problems in the energy use process.

[0085] The deep learning early warning unit is used to build an abnormal situation early warning model suitable for park energy monitoring and deploy the trained early warning model into the energy monitoring system.

[0086] When collecting a large amount of image and video data of the normal operation of the park's energy facilities and various abnormal situations, such as transformer failure causing oil spraying and fire, gas leakage causing explosion, photovoltaic panels being blocked by foreign objects causing a significant drop in power generation efficiency, etc., we organized professionals to annotate the data in detail, clarify the type of each abnormal situation, such as fire, leakage, blockage, etc., the severity, divided into minor, moderate, severe levels and the location of occurrence, accurate to the specific components or areas of the equipment and other information, and constructed a training data set containing several images and several video data.

[0087] Based on deep learning frameworks, such as TensorFlow or PyTorch, an abnormal situation warning model for campus energy monitoring is constructed. An optimized convolutional neural network (CNN) structure is adopted, which includes multiple convolutional layers (for extracting image features), pooling layers (for reducing data dimensions) and fully connected layers (for classification and prediction). The network parameters are carefully selected according to the characteristics of the abnormal situation and data characteristics, such as the convolution kernel size (selecting the appropriate size according to the size of equipment components and the feature scale, such as 3x3 or 5x5), step size (controlling the reduction ratio of the feature map), activation function (using the ReLU function to improve the efficiency of model training), etc.

[0088] The early warning model is fully trained using the training data set, and the weights and biases of the model are continuously adjusted through the back-propagation algorithm so that the model can accurately identify different types of abnormal situations. During the training process, an adaptive learning rate adjustment strategy is adopted, such as dynamically reducing the learning rate according to the training error and regularization techniques, such as L2 regularization to prevent overfitting. At the same time, data enhancement techniques, such as random cropping, rotation, and flipping images, are used to expand the training data to improve the generalization ability and stability of the model.

[0089] The trained deep learning model is deployed to the energy monitoring system to analyze the images and video data collected by the camera in real time. When the model detects an abnormal situation, it immediately issues an early warning signal, which includes the type of abnormality, such as smoke from the transformer, gas leakage, photovoltaic panel fire, etc., the location of the occurrence, which is located through the camera location information and the coordinates in the image, and is accurate to the specific equipment or area, such as "smoke from the A-phase bushing of transformer No. 1 in the substation", and the severity, which is determined according to the model's assessment score of the abnormal situation, such as detailed information such as moderate severity. At the same time, the park management personnel are notified through various means, and a striking early warning pop-up window pops up on the large screen of the park monitoring center, displaying the abnormal image and detailed information, accompanied by language The system will send a text message notification to the manager's mobile phone, including a summary of the abnormality and the degree of urgency; activate the sound and light alarm device, and send a strong sound and light alarm at the scene of the abnormality to ensure that the manager can obtain abnormal information in time and take corresponding measures. For example, when a gas leak is detected at a valve in the gas boiler room, the system will immediately issue an early warning, and the real-time image, location information and severity rating of the leaking valve will be displayed on the large screen of the monitoring center. The manager's mobile phone will receive a text message notification that "a gas leak has occurred at the valve in the gas boiler room [specific location], severity: moderate, please deal with it immediately", and the sound and light alarm device on site will be activated at the same time, reminding nearby personnel to evacuate quickly and prompting maintenance personnel to carry professional equipment to the scene for emergency treatment.

[0090] The emotion calculation module further includes:

[0091] Feedback collection unit, used to set up feedback collection terminals and online questionnaire platforms, as well as set up customer service hotlines;

[0092] Sentiment analysis unit, used for preprocessing and sentiment classification of feedback information in the form of text, speech and images;

[0093] The strategy adjustment unit is used to establish a correlation model between user emotions and energy allocation strategies, and to formulate energy allocation adjustment plans.

[0094] A touch screen feedback device is set up in the lobby of the park's office building, where employees can input their opinions on energy use, such as whether the air-conditioning temperature is comfortable. A QR code is also posted, and employees can scan it to enter the online feedback page and submit text or photo feedback, such as photos of damaged lighting equipment. Energy use questionnaires are sent to park companies via email on a regular basis, covering aspects such as energy supply stability and equipment ease of use. A customer service hotline is set up to record user feedback, such as complaints about power outages, and the collected feedback is categorized and sorted, such as energy supply, equipment use, and other categories based on feedback type.

[0095] For text feedback, after removing stop words, a simple bag-of-words model and naive Bayes classifier are used to perform sentiment classification into positive, negative, and neutral. For voice feedback, it is first converted into text and then sentiment analysis is performed. For image feedback, such as photos of employees frowning, the emotional tendency is judged through a simple expression recognition algorithm. The results of multiple feedback analyses are combined. For example, if most employees feedback that the air conditioning in a certain area is too cold, the overall emotional tendency is determined to be negative.

[0096] A simple correlation model is established. For example, when users in a certain area give negative feedback on temperature comfort, the air-conditioning temperature setting is adjusted appropriately. According to the actual energy supply situation in the park, such as the power load margin, an adjustment plan is formulated, such as increasing the air-conditioning temperature setting in the area during low-load periods to save energy. The adjustment instructions are sent to the air-conditioning equipment through the Internet of Things control system to achieve remote control and real-time monitoring of the effects, such as observing the temperature changes after adjustment through temperature sensor data.

[0097] The blockchain module further includes:

[0098] An encryption storage unit, used to pre-process and hash the energy facility monitoring data collected by the IoT sensor, and encrypt the energy facility monitoring data using an asymmetric encryption algorithm;

[0099] The consensus verification unit is used to ensure the consistency and immutability of energy facility monitoring data through the consensus mechanism of the blockchain network.

[0100] The energy data collected by the sensor, such as electricity, gas volume, equipment operation status data, etc., is preprocessed simply, such as removing obvious error values. The preprocessed data is hashed, such as using the SHA-1 algorithm to generate a summary, and then an asymmetric encryption algorithm, such as the RSA algorithm, is used. The public key is made public and the private key is kept by authorized personnel to encrypt the data and summary. The encrypted data block is uploaded to a simple blockchain network node composed of several servers in the park. Each data block contains the hash value of the previous data block to form a chain structure.

[0101] A simple Byzantine fault-tolerant consensus mechanism is adopted. When a node receives a new data block, it broadcasts it to other nodes. Other nodes verify whether the hash value of the data block is correct and whether the data format is compliant. If the majority of nodes pass the verification, the data block is added to the blockchain. For example, after a certain power data block is uploaded, the nodes verify that its hash value is consistent with the calculation result and the data format is correct. After reaching a consensus, it is stored to ensure the consistency and non-tamperability of the data. Authorized personnel can use the private key to decrypt and view the data for auditing and other work.
