Description

Technical Field

[0001] This invention relates to the field of smart park technology, and in particular to a data broadcasting system based on smart park management. Background Technology

[0002] With the acceleration of urbanization and the rapid development of information technology, smart parks, as an important component of urban intelligent construction, are gradually becoming a key force driving industrial upgrading and innovative development. Smart park management aims to leverage advanced technologies such as the Internet of Things (IoT), big data, cloud computing, and artificial intelligence to comprehensively perceive, intelligently analyze, and efficiently integrate various resources within the park, including infrastructure, energy, environment, and personnel, achieving automated, intelligent, and refined management of park operations. Through a smart park management system, managers can monitor the park's operational status in real time, optimize resource allocation, improve operational efficiency, and reduce management costs. Simultaneously, it provides a more convenient, comfortable, and safe working and living environment for businesses and employees within the park, enhancing the park's overall competitiveness and attractiveness.

[0003] Within the framework of smart park management, the data broadcasting system plays a crucial role. It serves as a bridge connecting various data sources within the park with management, responsible for collecting, organizing, and summarizing massive amounts of data from various subsystems such as security monitoring, energy management, and environmental monitoring systems. This data is then presented to management in an intuitive and easy-to-understand manner, such as through voice broadcasts and screen displays, providing timely and accurate feedback. Through the data broadcasting system, managers can quickly understand the park's key operational indicators and real-time dynamics without having to search through numerous complex systems, providing strong support for decision-making. For example, when a certain area within the park experiences excessive power load, the data broadcasting system can quickly issue an alarm, reminding managers to take timely measures to avoid potential power outages and ensure the normal operation of the park.

[0004] However, existing smart park data broadcasting systems still have some obvious limitations in practical applications. The most prominent problem is that most of these systems can only perform simple data collection and broadcasting functions, lacking the ability to analyze the data in real time. They simply present the collected data to management as is, making it difficult to identify potential problems and risks. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention aims to provide a data broadcasting system based on smart park management, which has data analysis capabilities and facilitates managers in identifying potential problems and risks.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A data broadcasting system based on smart park management includes a data acquisition module, which is signal-connected to a data display module and a voice broadcasting module via a control module. The control module is also signal-connected to a risk relationship storage unit, which is a database used to store risk data ranges and their corresponding risk types and risk handling methods. When the control module receives each set of park data transmitted by the data acquisition module, it calls the database in the risk relationship storage unit. When a set of park data falls within the risk data range, the control module controls the data display module to display the risk type and risk handling method, and controls the voice broadcasting module to broadcast the risk type and risk handling method.

[0008] Preferably, the data acquisition module includes a security data acquisition unit, an energy management data acquisition unit, and an environmental monitoring data acquisition unit; the security data acquisition unit is used to collect access control system data for each area within the park; the energy management data acquisition unit is used to collect electricity consumption data, water consumption data, and gas consumption data for each building within the park; and the environmental monitoring data acquisition unit is used to collect air quality data, temperature and humidity data, and noise data within the park.

[0009] Preferably, the control module includes a data preprocessing unit. After receiving the park data transmitted by the data acquisition module, the data preprocessing unit first preprocesses the park data. The preprocessing includes data cleaning to remove noise data and outliers, and data normalization to unify data dimensions. The preprocessed data is then used for comparison and analysis with the database in the risk relationship storage unit.

[0010] Preferably, the database within the risk relationship storage unit is classified and stored according to risk level, which is divided into low risk, medium risk, and high risk. When a set of park data falls within the risk data range, the control module controls the data display module to display the risk type and risk handling method in different colors according to the different risk levels. At the same time, the control module controls the voice broadcast module to broadcast the risk type and risk handling method at different speaking speeds and volume levels. The higher the risk level, the faster the speaking speed and the louder the volume.

[0011] Preferably, low-level risks are displayed in green, medium-level risks in yellow, and high-level risks in red.

[0012] Preferably, the control module is also signal-connected to a historical data storage unit, which is used to store park data and corresponding risk handling records within a certain period of time.

[0013] Preferably, after receiving new park data and determining the risk type, the control module retrieves historical processing records of the same risk type from the historical data storage unit, sends the corresponding historical processing records to the data display module for display, and sends them to the voice broadcast module for broadcast.

[0014] Preferably, the data display module includes a main display interface, which is used to display park data for each area within the park in real time, as well as the current risk types and risk handling methods.

[0015] Preferably, the system further includes a mobile terminal module, which is connected to the control module via a wireless communication network; when the control module detects that the park data falls within the risk data range, it sends risk notification information to the mobile terminal module, the risk notification information including the risk type, risk location, and risk handling method.

[0016] Preferably, the mobile terminal module is a smartphone or tablet.

[0017] The present invention has the following beneficial effects:

[0018] I. Data Analysis Capabilities Facilitate Managers' Identification of Potential Problems and Risks: This system possesses powerful data analysis capabilities, providing strong support for managers to identify potential problems and risks. Upon receiving each set of park data from the data acquisition module, the control module compares and analyzes the data against the database within the risk relationship storage unit. The data acquisition module covers multiple aspects, including security, energy management, and environmental monitoring. The collected data is comprehensive and diverse, including access control system data for various areas within the park, electricity, water, and gas consumption data for each building, as well as air quality, temperature, humidity, and noise data for the park. The data preprocessing unit within the control module preprocesses the collected park data, removing noise and outliers through data cleaning and normalizing the data to ensure accuracy and usability. The preprocessed data is then compared with the database in the risk relationship storage unit. When a set of park data falls within the risk data range, the system can promptly identify the risk type and provide corresponding risk handling methods. This comprehensive data acquisition, precise data preprocessing, and intelligent data comparison and analysis enable managers to quickly identify potential problems and risks during park operations and take preventative and remedial measures in advance.

[0019] II. Differentiated Display and Broadcasting Based on Risk Level: The database within the risk relationship storage unit is categorized and stored according to risk level: low risk, medium risk, and high risk. When a set of park data falls within the risk data range, the control module controls the data display module to show the risk type and risk handling method in different colors based on the risk level: low risk is displayed in green, medium risk in yellow, and high risk in red. Simultaneously, the voice broadcast module broadcasts the risk type and risk handling method at different speeds and volume levels; the higher the risk level, the faster the speech and the louder the volume. This differentiated display and broadcasting method allows managers to intuitively and quickly understand the severity of the risk, prioritize handling high risks, and improve the efficiency and targeting of risk management.

[0020] III. Historical Data Reference for Decision Support: The control module is also connected to a historical data storage unit to store park data and corresponding risk handling records for a specific period. Upon receiving new park data and determining the risk type, the control module retrieves historical handling records of the same risk type from the historical data storage unit and sends these records to the data display module for display, and simultaneously to the voice broadcast module for announcement. This provides managers with historical references, helping them understand the handling methods and effects of similar risks in the past, thereby enabling them to make more scientific and reasonable decisions and improve the success rate and efficiency of risk handling.

[0021] IV. Real-time Display of Park Data and Risk Information: The data display module includes a main display interface that can display real-time park data for each area, as well as the current types of risks and risk handling methods. Managers can use the main display interface to monitor the overall operation of the park at any time, promptly identify abnormal data and potential risks, and improve work efficiency and the timeliness of information acquisition without switching between multiple systems or interfaces.

[0022] V. Real-time Mobile Terminal Notification: The system also includes a mobile terminal module, which connects to the control module via a wireless communication network. The mobile terminal module can be a smartphone or tablet. When the control module detects that park data falls within the risk data range, it sends a risk notification to the mobile terminal module, including the risk type, risk location, and risk handling method. This allows managers to receive timely risk notifications even when they are not physically present in the park, enabling them to understand the park's situation immediately and take appropriate measures, thus improving the timeliness and flexibility of park management.

It should be understood that the following drawings only show some embodiments of the present invention and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0024] Figure 1 This is a schematic diagram of the connection relationship in the first embodiment of the present invention.

[0025] Figure 2 This is a schematic diagram of the connection relationship in the second embodiment of the present invention. Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] First embodiment

[0028] like Figure 1 As shown, a data broadcasting system based on smart park management includes a data acquisition module, which is connected to a data display module and a voice broadcasting module via a control module. The control module is also connected to a risk relationship storage unit, which is a database used to store risk data ranges and their corresponding risk types and risk handling methods. When the control module receives each set of park data transmitted by the data acquisition module, it calls the database in the risk relationship storage unit. When a set of park data falls within the risk data range, the control module controls the data display module to display the risk type and risk handling method, and controls the voice broadcasting module to broadcast the risk type and risk handling method.

[0029] like Figure 1As shown, the data acquisition module first starts working, collecting various types of information within the park. The collected data broadly covers multiple dimensions of park operations, providing basic data support for the entire system. Each set of collected park data is transmitted to the control module via a signal connection. While receiving data, the control module calls the database in the risk relationship storage unit connected to the signal. This database pre-stores risk data ranges, their corresponding risk types, and risk handling methods. Subsequently, the control module compares and analyzes the received park data with the risk data ranges in the database to determine whether the set of park data falls within a certain risk data range. If a set of park data falls within a risk data range, the control module will act immediately. On one hand, it controls the data display module to show the corresponding risk type and risk handling method, allowing managers to obtain risk-related information intuitively; on the other hand, it controls the voice broadcast module to broadcast the risk type and risk handling method, promptly notifying managers via voice to ensure they are aware of the risk situation regardless of whether they are near the display device. If the park data does not fall within any risk data range, the system will not trigger specific display and broadcast actions from the data display module and the voice broadcast module, but will continue to wait for the collection and subsequent processing of the next set of park data. Through this process, the entire system enables real-time collection and analysis of park data, and can promptly convey risk information to management personnel, helping them to respond to potential problems and risks in a timely manner.

[0030] like Figure 1 As shown, the data acquisition module includes a security data acquisition unit, an energy management data acquisition unit, and an environmental monitoring data acquisition unit. The security data acquisition unit is used to collect access control system data for each area within the park. The energy management data acquisition unit is used to collect electricity consumption data, water consumption data, and gas consumption data for each building within the park. The environmental monitoring data acquisition unit is used to collect air quality data, temperature and humidity data, and noise data within the park.

[0031] The data acquisition module, serving as the source of information, collaborates with the security data acquisition unit, energy management data acquisition unit, and environmental monitoring data acquisition unit to comprehensively collect various types of data within the park. The security data acquisition unit is closely connected to the access control systems of various areas within the park, obtaining detailed information on personnel entry and exit through real-time interaction. This includes personnel identification data, such as card swipe information and facial recognition results, accurately determining the identity of those entering the park; entry and exit times are accurate to the second, clearly indicating the specific time periods of personnel activity; and entry and exit areas clearly identify which gate or specific area a person enters or exits, aiding in the analysis of personnel flow patterns and the park's security status. The energy management data acquisition unit meticulously monitors the energy usage of each building within the park. For electricity consumption data, it records in detail the electricity consumption of different buildings at different times, including not only total electricity consumption but also breakdowns to the electricity consumption of each floor and functional area. By analyzing this data, it is possible to understand peak and off-peak energy usage periods and differences in electricity consumption across different areas, providing a basis for energy conservation management. In terms of water consumption data collection, the system can accurately measure the water consumption of each building, distinguish between domestic and industrial water use, and record the temporal distribution of water usage to facilitate the detection of abnormal water usage. Gas consumption data collection includes information such as gas usage volume and frequency, helping to understand the gas energy usage status within the park. The environmental monitoring data collection unit is responsible for collecting environmental parameters within the park to assess its environmental quality. It monitors air quality data in real time, acquiring the concentrations of pollutants such as PM2.5, PM10, sulfur dioxide, and nitrogen oxides through sensors to understand the degree of air pollution and the main sources of pollutants. Temperature and humidity data collection uses temperature and humidity sensors distributed throughout the park to obtain real-time temperature and humidity information at different locations, which is crucial for ensuring the comfort of personnel and the normal operation of equipment within the park. Noise data collection monitors the noise intensity in various areas of the park, identifies noise sources, and assesses the impact of noise on the park's environment and personnel.

[0032] like Figure 1 As shown, the control module includes a data preprocessing unit. After receiving the park data transmitted by the data acquisition module, the data preprocessing unit first preprocesses the park data. The preprocessing includes data cleaning to remove noise data and outliers, and data normalization to unify the data units. The preprocessed data is then used for comparison and analysis with the database in the risk relationship storage unit.

[0033] After the data acquisition module transmits the collected park data to the control module, the data preprocessing unit in the control module immediately initiates the preprocessing process. Due to various factors that may interfere with the data acquisition process, such as equipment malfunctions and external environmental interference, noisy data and outliers may appear in the acquired data. The data cleaning stage uses specific algorithms and rules to filter and correct this data. For example, for values ​​that significantly exceed the normal range, such as a sudden spike or drop in power consumption at a certain moment, comparison with historical data and data from adjacent time points determines whether it is an outlier and takes appropriate action, such as removing it or replacing it with a reasonable value. For missing values ​​in the data, interpolation, averaging, and other methods are used to fill in the missing values ​​based on the data characteristics and relevant patterns to ensure data integrity. Different types of data have different dimensions and numerical ranges. For example, power consumption data may be large values ​​(e.g., kilowatt-hours), while temperature and humidity data are relatively small values ​​(e.g., degrees Celsius, percentages). This difference can make subsequent data comparison and analysis difficult. Data normalization is the process of unifying data with different dimensions into the same numerical range, typically mapping data to the interval [0, 1] or [-1, 1]. Through data normalization, the influence of dimensions can be eliminated, making different types of data comparable and facilitating subsequent data analysis and modeling.

[0034] The data processed by the preprocessing unit is sent to the control module for further analysis. The control module calls the database in the risk relationship storage unit. This database is pre-built and stores various risk data ranges and their corresponding risk types and risk handling methods. These risk data ranges are determined based on the actual situation of the park, historical data, and expert experience, covering multiple aspects of risks such as security, energy, and environment. For example, for security risks, the time range of illegal intrusion and abnormal personnel identity may be set as risk data ranges; for energy risks, data ranges such as excessive electricity consumption and water waste are set; for environmental risks, data ranges such as exceeding air quality standards and abnormal temperature and humidity are set. At the same time, corresponding risk handling methods are also formulated for each risk type. For example, for illegal intrusion risks, the handling method may be to trigger the alarm system and notify security personnel; for energy waste risks, the handling method may be to adjust equipment operating parameters and remind relevant personnel. The control module compares the preprocessed park data with the risk data ranges in the database one by one. If a set of park data falls into a certain risk data range, it is determined that the park has the corresponding risk type, and the corresponding risk handling method is retrieved from the database. For example, if the power consumption data at a certain moment exceeds the high-risk range for excessive power consumption set in the database, the control module will determine that there is a risk of power waste in the park and obtain corresponding handling suggestions, such as checking for abnormal equipment operation or adjusting the power consumption plan. If the park data does not fall within any risk data range, it means that the park is currently operating normally, and the control module continues to wait for the next set of park data to arrive and repeat the above process.

[0035] like Figure 1 As shown, the database within the risk relationship storage unit is categorized and stored according to risk level: low risk, medium risk, and high risk. When a set of park data falls within a risk data range, the control module controls the data display module to display the risk type and risk handling method in different colors based on the risk level. Simultaneously, the voice broadcast module controls the voice broadcast module to announce the risk type and risk handling method at different speeds and volumes; the higher the risk level, the faster the speech and the louder the volume. After the data acquisition module collects a set of park data and transmits it to the control module, the control module calls the database within the risk relationship storage unit to compare and analyze the received park data with the risk data range stored in the database. If the set of park data falls within a certain risk data range, it means that a corresponding risk situation has occurred in the park. At this time, the control module will proceed with the subsequent differentiated processing flow based on the risk level corresponding to that risk data range. If it does not fall within any risk data range, the system continues to wait for the collection and processing of the next set of park data.

[0036] Once the risk level is determined, the control module controls the data display module to show the risk type and handling method using different colors. Specifically, low-level risks are displayed in green, medium-level risks in yellow, and high-level risks in red. This intuitive color differentiation allows managers to quickly visually identify the severity of the risk and focus on the high-level risks that require immediate attention and handling. Simultaneously, the control module also controls the voice broadcast module to announce the risk type and handling method at different speeds and intensities. The higher the risk level, the faster the speech and the louder the voice. This design leverages human sensitivity to sound; high-speed speech and loud voices more effectively attract the attention of managers, especially when they may not be focused on the display interface. The strong auditory stimulation ensures that managers are promptly aware of the existence of high-level risks so that they can take swift action.

[0037] like Figure 1 As shown, the control module is also signal-connected to a historical data storage unit, which stores park data and corresponding risk handling records for a certain period of time. After receiving new park data and determining the risk type, the control module retrieves historical handling records of the same risk type from the historical data storage unit and sends these records to the data display module for display and to the voice broadcast module for announcement. The historical data storage unit, signal-connected to the control module, primarily stores park data for a certain period of time and records the handling of various risks that occurred during those time periods. This historical data encompasses various information about the park under different operating conditions and experience in dealing with risks. Accumulating over time, it forms a rich data resource library, providing valuable reference for subsequent risk handling.

[0038] The data acquisition module collects relevant data from various areas within the park in real time and transmits it to the control module. Upon receiving new park data, the control module accesses the database within the risk relationship storage unit (which stores the range of risk data, its corresponding risk types, and risk handling methods), comparing the newly received park data with the risk data range in the database. Through this comparison, the control module can accurately determine the risk type corresponding to the current park data, i.e., determine the current risk situation faced by the park. After determining the risk type corresponding to the new park data, the control module, due to its signal connection with the historical data storage unit, sends a retrieval command to the historical data storage unit to search for historical processing records with the same risk type as the currently determined one. The historical data storage unit, according to the command, searches and matches its vast stored data, extracting the historical processing records that meet the criteria.

[0039] like Figure 1 As shown, the data display module includes a main display interface, which displays real-time data for each area within the park, as well as the current risk types and risk handling methods. After the control module obtains historical handling records for the same risk type, it integrates these records with the current risk type and handling method. Then, the control module sends the integrated information to the data display module and the voice broadcast module. The main display interface of the data display module displays real-time data for each area within the park, the current risk types, and risk handling methods, while also displaying retrieved historical handling records for the same risk type. This allows managers to intuitively see the current risk situation and how similar risks were handled in the past. The voice broadcast module broadcasts the risk type, risk handling method, and historical handling records in voice format, ensuring that managers can promptly understand risk information and historical handling experience even if they are not focused on the display interface. This provides managers with a comprehensive reference for formulating current risk handling strategies, improving the efficiency and accuracy of risk handling, and better ensuring the safe and stable operation of the park.

[0040] Second embodiment

[0041] like Figure 2 As shown, the system also includes a mobile terminal module, which is connected to the control module via a wireless communication network. When the control module detects that the park data falls within the risk data range, it sends a risk notification to the mobile terminal module. The risk notification includes the risk type, risk location, and risk handling method. The mobile terminal module is a smartphone or tablet.

[0042] The data acquisition module continuously collects various types of information within the park, covering multiple dimensions of park operations, such as security, energy, and environment. The collected park data is transmitted to the control module in real time. Upon receiving the data, the control module accesses a database pre-stored in the risk relationship storage unit. This database contains various risk data ranges, their corresponding risk types, and risk handling methods. The control module compares and analyzes the received park data against the risk data ranges in the database to determine if the park data falls within a risk range, thus detecting any potential risks within the park. When the control module detects that park data falls within a risk data range, it determines that a risk has occurred in the park. At this point, the control module generates a risk notification message containing the risk type, risk location, and risk handling method, based on preset rules and information from the database. Subsequently, the control module uses a wireless communication connection with the mobile terminal module, employing a 4G / 5G communication module or Wi-Fi, to accurately send the generated risk notification message to the mobile terminal module. The mobile terminal module is configured as a common device such as a smartphone or tablet, which is portable and easy to operate. When the mobile terminal module receives a risk notification from the control module, it clearly displays the information to management personnel through its interface. Management personnel can intuitively see the risk type, understand the specific location of the risk within the park, and the appropriate handling methods. In this way, management personnel, regardless of their location, can promptly grasp the dynamics of park risks and make rapid decisions and take corresponding measures based on the notification information, effectively improving the timeliness and efficiency of risk response and ensuring the safe and stable operation of the park.

[0043] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
