Description

Technical Field

[0001] This utility model relates to the field of monitoring technology, and in particular to a remote monitoring device for photovoltaic power plants based on three-dimensional digital twin technology. Background Technology

[0002] With global photovoltaic (PV) installed capacity exceeding 1 TW, the continuous expansion of power plant scale has led to increasingly widespread equipment distribution, with single-site coverage areas often exceeding 10 square kilometers. Traditional manual inspections are proving inadequate in addressing hidden faults such as hot spot effects and PID degradation. On average, maintenance personnel need 45 minutes to locate anomalies, and issues such as component performance degradation and loose electrical connections are difficult for manual inspection and monitoring systems to identify. Frequent overheating and shutdown of control units during high-temperature seasons further exacerbate power generation losses. Therefore, the use of modern monitoring technology for comprehensive remote monitoring of PV power plants from all angles is becoming increasingly common.

[0003] The existing remote monitoring devices for photovoltaic power plants adopt a linear architecture of "sensor → PLC → two-dimensional interface". The operating data collected by the sensors is initially processed by the PLC and presented on the observation interface in the form of tables or curves. However, the two-dimensional data listing cannot intuitively show the spatial topology of the equipment. The fault location of the power plant requires manual comparison with drawings. The operating data and the physical model of the equipment are in a state of separation, which leads to a decrease in the real-time monitoring efficiency of the power plant. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] Reference Figure 1 and Figure 5 The present invention provides an embodiment of a photovoltaic power station remote monitoring device based on three-dimensional digital twin technology, which includes a functional module and a display and interaction module. The functional module and the display and interaction module are electrically connected through a communication unit. The functional module includes a data acquisition unit, a data processing unit, a data storage unit and an MCU chip unit. The MCU chip unit includes an MCU chip and a heat dissipation component.

[0039] Specifically, this device includes functional modules, an interactive display module, and a communication unit. The functional modules include a data acquisition unit, a data processing unit, a data storage unit, and an MCU chip unit. The interactive display module includes a display screen and a touchscreen terminal. All modules are assembled within the photovoltaic power station and connected via a backplane bus. The data acquisition unit connects to the power station's sensors via interfaces such as RS485 and Modbus. The acquired data is sent to the data processing unit via data transmission elements. The data processing unit uses an embedded processor and an FPGA chip for data cleaning and anomaly detection. The processed data is stored in the data storage unit (using an SSD array) and simultaneously pushed to the MCU chip. The MCU chip has 3D modeling, control, and application capabilities, and is equipped with a GPU accelerator card. It generates a 3D geometric model based on the device parameter library and uses a texture mapping unit to map the actual data. The time-state (such as temperature distribution) is mapped to model color changes; the 3D model is then pushed to the visualization module, converting it into a format that can be displayed in a browser. Users can access the web service through a PC display or mobile touchscreen terminal to achieve multi-view monitoring and interactive operation; at the same time, the application function module of the MCU chip runs on the application server, calling historical data in the data storage unit for fault diagnosis and operation and maintenance decisions, and the generated control commands are sent to the data acquisition module through the control unit to adjust the acquisition strategy; the communication unit adopts a dual network port design, with the main link being fiber optic communication (for remote data transmission) and the backup link being 4G / 5G wireless communication; and the control unit in the MCU chip uses a PLC to monitor the load status of each module in real time. When the load of the data processing module exceeds 80%, the acquisition frequency of non-critical data is automatically reduced.

[0040] Reference Figure 5 The heat dissipation component includes a temperature sensor and a cooling fan. The output of the temperature sensor is electrically connected to the data acquisition unit, and the cooling fan is electrically connected to the MCU chip.

[0041] Specifically, a temperature sensor is added outside the MCU chip and electrically connected to the data acquisition unit. The temperature threshold is set to 60 degrees Celsius. The temperature sensor senses the real-time hardware temperature and transmits it to the data acquisition unit. The data acquisition unit transmits the data to the data processing unit, which then stores and records the data before transmitting it back to the MCU chip. The MCU chip then adjusts the cooling fan speed in real time according to the temperature. When the temperature is below 40 degrees Celsius, the cooling fan is reduced or turned off to save energy. When the temperature exceeds the threshold, the fan speed is increased to accelerate heat dissipation and ensure stable operation of the control unit.

[0049] Specifically, the data collected by the data acquisition unit is first transmitted to the preprocessing element in the data processing unit. After cleaning, the effective data is filtered and converted into a specified format. Then, the data is subjected to anomaly detection through heterogeneous computing elements. The heterogeneous computing elements include multiple CPU clusters to dynamically load preprocessing plugins and coordinate the workflow of each hardware unit.
