The Application of Puzhi in Power Monitoring Scenarios

With the rapid development of modern industry and the increasing complexity of power systems, power monitoring plays a crucial role in ensuring the safe, stable, and efficient operation of power systems. Accurate power monitoring can timely identify potential issues in the power system, such as abnormal power quality and equipment failure risks, thus providing strong support for the optimization and maintenance of the power system. The Puzhi development board, with its outstanding performance and rich interface resources, provides a reliable hardware foundation for building an efficient and precise power monitoring system.

1. Data Acquisition Layer: Various high-precision power sensors, such as voltage sensors, current sensors, and power sensors, are selected to collect real-time data from the power system. These sensors convert the collected analog signals into digital signals and transmit them to the Puzhi development board through its rich peripheral interfaces, such as ADC and SPI interfaces. For example, the voltage sensor collects the grid voltage signal in real-time, which is then conditioned to fit the signal range suitable for the development board, and the digital signal is input to the board via the ADC interface.

2. Data Processing and Analysis Layer: The Puzhi development board is equipped with a high-performance processor core that can quickly process and analyze the collected power data. The board runs customized data analysis algorithms to perform real-time calculations on power data, such as calculating power quality indicators (harmonic content, voltage deviation, three-phase imbalance, etc.) and monitoring equipment operating status (power factor, active power, reactive power, etc.). Through these analyses, it can promptly identify anomalies in the power system and provide data support for subsequent decision-making.

3. Data Transmission and Storage Layer: The development board supports various communication methods, such as Ethernet, Wi-Fi, and 4G, allowing processed data to be transmitted in real-time to remote monitoring centers or cloud servers. Additionally, the board is equipped with large-capacity storage devices, such as SD cards and eMMC, for local storage of historical data for future queries and analysis. For instance, when a fault occurs in the power system, historical power data before and after the fault can be retrieved from local storage for fault analysis.

4. User Interaction Layer: A user-friendly interface can be implemented through PC software, web pages, or mobile apps. Users can view the operating status of the power system, monitoring data reports, alarm information, etc., in real-time on the interface, and can also set parameters and remotely control the monitoring system. For example, users can check power monitoring data anytime and anywhere through a mobile app, and can take timely action upon receiving alarm notifications.

1. Data Acquisition and Processing Software: A dedicated data acquisition program is developed to achieve real-time collection and preprocessing of data from various power sensors. During data processing, digital filtering algorithms are used to eliminate noise interference, improving data accuracy. At the same time, efficient algorithms are employed to calculate various power parameters, such as harmonic analysis using Fast Fourier Transform (FFT) algorithms, ensuring precise monitoring of power quality.

2. Communication Protocol Software: Software supporting various communication protocols, such as Modbus and MQTT, is developed to facilitate data transmission between the development board and remote monitoring centers or cloud servers. These protocols ensure stable data transmission and efficient interaction, meeting different user needs for data transmission.

3. Data Analysis and Alarm Software: Data analysis software is developed to deeply mine and analyze the collected power data. Reasonable alarm thresholds are set, and when monitoring data exceeds normal ranges, alarm signals are promptly issued, such as notifying relevant personnel via SMS, email, or app push notifications. Additionally, historical data is statistically analyzed to generate trend charts and reports, providing data basis for the optimization and maintenance of the power system.

4. User Interface Software: A simple and intuitive user interface software is developed to facilitate convenient interaction between users and the monitoring system. The interface design focuses on user experience, displaying power monitoring data in forms such as charts and numbers, allowing users to quickly understand the operating status of the power system. At the same time, operation guides and help documents are provided to reduce user difficulty.

1. High Precision Monitoring: With high-precision power sensors and strong data processing capabilities, the Puzhi development board can achieve high-precision monitoring of various parameters in the power system, ensuring timely detection of subtle abnormal changes.

2. Strong Real-time Performance: The rapid data acquisition and processing speed, along with efficient communication methods, ensure real-time transmission and feedback of monitoring data, enabling relevant personnel to take timely measures in response to emergencies.

3. High Flexibility: The rich interface resources and support for various communication methods allow the system to flexibly adapt to different power monitoring scenarios and user needs, facilitating system expansion and upgrades.

4. High Reliability: The development board adopts industrial-grade design, providing good stability and anti-interference capabilities, ensuring reliable operation in complex power environments. Additionally, data storage and backup mechanisms ensure data security and integrity.

1. Power Monitoring in Industrial Enterprises: Industrial enterprises have high power consumption and complex equipment. The power monitoring system built with the Puzhi development board can monitor the operating status of the internal power system in real-time, promptly identify equipment failures and energy waste issues, providing strong support for energy management and equipment maintenance, reducing electricity costs and equipment failure rates for enterprises.

2. Smart Grid Monitoring: In the construction of smart grids, power monitoring is a key link in achieving intelligent management of the grid. The Puzhi development board can be used to monitor parameters such as power quality and load changes in the grid, providing data basis for grid scheduling and optimization, improving the operational efficiency and reliability of the grid.
