During operation, the various electronic components and modules inside the terminal generate a lot of heat. When operating at low power for a period of time, the heat generated is relatively small, and the existing methods do not put much pressure on its heat dissipation. However, when operating at high power, the heat generated is large and concentrated. At this time, conventional heat dissipation methods cannot effectively and quickly dissipate heat from the acquisition terminal.

Detailed Implementation
[0028] 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.
[0029] like Figure 1-6As shown, the device includes a housing 10, with a first side plate 20 and a second side plate 30 on each side. The first side plate 20 has a connection port 203 for connecting external devices, a monitoring unit 201, and a distribution transformer monitoring unit 202. The monitoring unit 201 and the distribution transformer monitoring unit 202 are directly or through an interface circuit connected to a processor module to form an integrated monitoring system. The processor module analyzes and processes the received data and uploads it to a remote monitoring center through a communication module. The second side plate 30 has a start button 303 for activating the acquisition terminal, a first indicator light 301, and a second indicator light 302. The first indicator light 301 is electrically connected to the monitoring unit 201, and the second indicator light 302 is electrically connected to the distribution transformer monitoring unit 202. Both the first side plate 20 and the second side plate 30 are detachably and fixedly connected to the housing 10 by a fixing nut 60.Heat dissipation plates 40 are provided on two sides of the housing 10 adjacent to the side plates. The heat dissipation plates 40 are embedded in both sides of the housing 10. Two symmetrically arranged guide plates 402 are provided inward on the heat dissipation plates 402. Limiting plates 403 are provided on the guide plates 402. The heat dissipation plates 40 on both sides are installed in the housing 10 by interlocking with the limiting plates 403. The guide plates 402 and the limiting plates 403 can slide relative to each other. A notch is opened on the side of the guide plate 402 away from the heat dissipation plate 40. The limiting plate 403 extends away from the guide plate 402 at the notch. The heat sink 40 is exposed, and when the two heat sinks 40 are installed, the guide plate 402 and the limiting plate 403 are placed symmetrically around the center. The two limiting plates 403 can limit each other, thereby achieving the purpose of installing the heat sink 40. This can prevent external dust and other objects from entering the housing 10 and affecting the electronic components inside the housing 10. The guide plate 402 also has a connecting rod cavity 405 and a sealing cavity 408. The connecting rod cavity 405 is connected to the notch, and a connecting rod 404 is slidably arranged inside the connecting rod cavity 405. A sealing block 407 is slidably arranged inside the sealing cavity 408. The sealing block 407 and the connecting rod 404 are connected by a connecting shaft. 406 are fixed together. The sealed cavity 408 is divided into a sealed space by a sealing block 407. This space is filled with either paraffin wax or grease. The melting point of the paraffin wax is between 40-60℃. When the paraffin wax melts, it expands in the sealed space of the sealed cavity 408, allowing it to move through the sealing block 407. When it solidifies, it contracts, causing the sealing block 407 to retract. A main limiting block 4031 is fixed on the limiting plate 403. The main limiting block 4031 allows the two limiting plates 403 to limit each other, completing the installation. Heat sinks are provided on both ends of the guide plate 402. The heat sensing groove 4022 is located in the sealed cavity 408. Several heat-conducting ribs 4023 are evenly distributed on the inner wall of the heat sensing groove 4022. The heat sensing groove 4022 allows for stable and minimal heat transfer to the sealed cavity 408. Furthermore, the heat-conducting ribs 4023 increase the contact area with hot air, accelerating both heat dissipation and heat absorption. A secondary limiting block 4021 is also provided at the bottom of the guide plate 402 to limit the maximum distance the guide plate 402 can be pushed out.
[0030] The housing 10 of the data acquisition terminal is made of high-strength aluminum alloy, which has good corrosion resistance and heat dissipation performance. The surface of the housing 10 is sandblasted and anodized to enhance its wear resistance and aesthetics. The internal layout of the housing 10 is reasonable, with sufficient space between each module for heat dissipation and maintenance. The housing 10 also features a waterproof and dustproof sealing structure to ensure stable operation even in harsh outdoor environments. The processor module incorporates intelligent algorithms to preprocess monitoring data, detect anomalies, and provide fault warnings. The processor module is the core of the data acquisition terminal, employing a high-performance embedded processor, such as the ARM Cortex-A series, equipped with sufficient RAM and Flash storage space. The processor is responsible for receiving raw data from each monitoring unit and performing tasks such as data preprocessing, analysis, storage, and transmission. To achieve efficient data processing, the processor integrates a dedicated DSP (Digital Signal Processor) unit for signal processing and data analysis.
[0031] Furthermore, in one embodiment of the present invention, a solar panel 101 is provided on the upper end of the housing 10; the solar panel 101 can directly convert solar radiation energy into electrical energy, providing a stable and reliable energy supply for the data acquisition terminal. This means that in remote areas where the power grid supply is unstable or cannot be connected to the grid, the data acquisition terminal can still work normally, enhancing its adaptability and reliability; solar energy is a clean and renewable energy source, and using the solar panel 101 for power supply can significantly reduce dependence on and consumption of traditional energy sources, reduce carbon emissions, and help protect the environment and promote sustainable development; the solar panel 101 can adopt a modular design, facilitating installation and removal on the housing 10 of the data acquisition terminal. At the same time, since the solar panel 101 typically has high reliability and stability, its maintenance cost is also relatively low.
[0032] Furthermore, in one embodiment of the present invention, a reinforcing rib 102 is provided on the other side of the housing 10 adjacent to the side plate. A plurality of heat dissipation holes 401 are provided on the heat dissipation plate 40, and a handle is also provided on the heat dissipation plate 40. When the handle is pulled outward, the sealing block 407 cannot move due to the sealed space within the sealing cavity 408. At this time, the pulling force acts on the two main limiting blocks 4031, which are arc-shaped. When the handle is pulled forcefully, the two main limiting blocks 4031 can disengage from their interlocking state, thereby achieving the purpose of removing the heat dissipation plate 40. The reinforcing rib 102, as a supporting structure inside the housing 10, can significantly improve the overall rigidity and strength of the housing 10. When subjected to external pressure or impact, the reinforcing rib 102 can effectively disperse stress, preventing the housing 10 from deforming or cracking, thereby protecting the safety of the internal electronic components. The heat dissipation holes 401 are important channels for heat dissipation on the housing 10. When the data acquisition terminal operates for a long time, the internal electronic components will generate a large amount of heat. The heat dissipation holes 401 can effectively expel heat from the exterior of the housing 10, reducing the internal temperature and preventing overheating damage or performance degradation of components. The design combining the reinforcing ribs 102 with the heat dissipation holes 401 enhances both the structural strength and stability of the housing 10 and improves the equipment's heat dissipation performance. This design allows the dedicated transformer data acquisition terminal to handle complex and changing outdoor working environments with greater ease, providing long-term, stable, and accurate monitoring data, thus offering strong support for the construction and operation of the smart grid.
[0033] Furthermore, in one embodiment of the present invention, a bracket 70 is provided at the bottom of the housing 10, and the bracket 70 is fixedly connected to the housing 10 by fastening screws 701. The bracket 70 serves as the contact point between the housing 10 and the ground or other mounting surfaces, providing stable support and preventing the data acquisition terminal from shifting or tipping over due to vibration, shaking, or external forces during operation. This is crucial for ensuring the stable operation of the data acquisition terminal and extending its service life. The design of the bracket 70 also reduces the impact of external environmental vibrations on the data acquisition terminal to a certain extent, protecting internal electronic components from damage and improving the reliability of the equipment. The fixed connection between the bracket 70 and the housing 10 by fastening screws 701 allows the data acquisition terminal to be adjusted in position and angle according to actual needs during installation to adapt to different installation environments and requirements. When maintenance or repair of the data acquisition terminal is required, it can be easily removed from its installation position by disassembling the fastening screws 701, facilitating subsequent operations.
[0034] An auxiliary heat dissipation assembly 50 is also provided inside the guide plate 402. The auxiliary heat dissipation assembly 50 includes a main rack 501, a secondary rack 503, and a connecting rod 504. Both racks slide within the guide plate 402. The main rack 501 and the secondary rack 503 are meshed together by a gear 502, which rotates within the guide plate 402. One end of the connecting rod 504 is fixed within the secondary rack 503, and the other end is fitted with a fan 508 via a bearing. The fan is located within the heat dissipation plate 40, and its blades are angled to ensure that when the equipment is installed outdoors, the airflow is drawn into the equipment as the fan rotates. The two fans are tilted in opposite directions. When airflow blows from the same side, one fan blows air while the other draws in air, allowing for rapid airflow and exchange between the inside and outside of the equipment, further enhancing the heat dissipation effect. Furthermore, when airflow blows from the front of the heat sink, it can directly pass through the heat sinks on both sides for rapid air exchange. One end of the main rack 501 is connected to the limiting plate 403. A guide hole 506 is provided in the guide plate 402, which also penetrates the heat sink 40. A connecting rod 504 is located within the guide hole 506. A filter plate 507 is fixed to the inner wall of the guide hole 506 at the heat sink 40 for filtration. External dust and other debris are filtered out. The connecting rod 504 passes through the filter plate 507 and is slidably connected to it. The guide plate 402 has connecting holes 505 on both end faces, located halfway up the guide hole 506. When air flows, airflow enters through the connecting holes 505, while unfiltered dust carried by the airflow continues to move due to inertia and remains within the guide hole 506, effectively preventing a large amount of dust from entering the equipment. The connecting holes 505 and the guide hole 506 are connected. When the internal temperature of the equipment is high, the two heat dissipation plates 40 open outwards. At this time, the limiting plate 403 and the guide plate 402 move relative to each other, thus driving the main rack 501. The sliding mechanism, via gear 502, drives the secondary rack 503 to slide, thereby moving the connecting rod 504 away from the limiting plate 403. At this time, the fan 508 can be extended outside the heat sink 40. If there is airflow outside, the fan 508 will rotate. The rotation of the fan 508 will accelerate the airflow inside the equipment. To prevent dust and debris from entering the equipment, the heat sink 40 will only have a small gap when it is opened. At this time, the fan 508 accelerates the airflow inside the equipment, which can further accelerate the air conversion inside the equipment, thereby improving the heat dissipation effect of the equipment while ensuring a reduction in dust ingress.
[0035] Furthermore, in one embodiment of the present invention, a remote upgrade interface supporting online firmware and algorithm upgrades is also included; the acquisition terminal has a built-in high-capacity Flash storage chip for storing historical data and firmware programs. Historical data can be uploaded to a remote monitoring center or exported to a local storage device as needed. To facilitate subsequent function expansion and maintenance, the acquisition terminal is also designed with a remote upgrade interface, supporting the receipt of firmware update packages sent by a remote server via a wireless network, thereby realizing online upgrades of the device.
[0036] The housing 10 also includes a data acquisition module, a data processing module, a communication module, a power management module, at least one new energy power generation monitoring unit 201, at least one distribution transformer monitoring unit 202, and a display unit. The new energy power generation monitoring unit 201 mainly includes monitoring sensors for photovoltaic power generation and wind power generation. For photovoltaic power generation, high-precision current and voltage sensors are used and installed at the output end of the photovoltaic panel to monitor the output current and voltage of the photovoltaic panel in real time, thereby calculating the generated electricity. At the same time, the inverter status monitoring module obtains the inverter's operating efficiency, fault information, etc. For wind power generation, additional monitoring sensors for environmental parameters such as wind speed, wind direction, and temperature may be required.
[0037] The data acquisition module is connected to the new energy power generation equipment and the distribution transformer respectively, and is used to collect the operating data of both in real time;
[0038] The data processing module processes and analyzes the collected data according to a preset algorithm and generates a monitoring report. The data processing module has a built-in algorithm for identifying the characteristics of new energy power generation and a distribution transformer health assessment model, which can automatically identify the type of new energy power generation and assess the operating status of the distribution transformer, so as to achieve accurate monitoring and early warning.
[0039] Working Principle: After startup, the data acquisition terminal first performs self-checks and initialization to confirm that all modules are properly connected and in standby mode. Then, it begins collecting status data from new energy power generation equipment and distribution transformers on a timed or on-demand basis. The processor module preprocesses and analyzes the collected data to determine if any abnormalities or faults exist. If an abnormality or fault is detected, an early warning mechanism is immediately triggered, and alarm information and detailed data are reported to the remote monitoring center via the communication module. Simultaneously, the corresponding alarm information is displayed on the display unit, prompting maintenance personnel to handle the situation promptly. Maintenance personnel can view historical data, alarm records, or modify equipment parameters as needed. Finally, upon receiving a remote upgrade command, the data acquisition terminal automatically downloads and installs the update package, completing the online firmware upgrade. This dedicated transformer data acquisition terminal, supporting monitoring of new energy and distribution transformers, highly integrates new energy power generation monitoring and distribution transformer monitoring functions. Through a carefully designed hardware architecture and software algorithms, it achieves efficient management of multiple aspects of the power system. The new energy power generation monitoring unit 201 accurately captures the working status of photovoltaic panels, wind power equipment, etc., providing data support for optimizing new energy grid connection; the distribution transformer monitoring unit 202 comprehensively monitors the health status of distribution transformers, preventing potential faults and ensuring stable grid operation; each sensor module is connected to the processor module via wired or wireless means. The processor module uses algorithms to analyze the data, calculate and identify the health status of the distribution transformers, and immediately triggers an early warning mechanism upon detecting an anomaly, reporting the alarm information and detailed data to the remote monitoring center via the communication module. Simultaneously, the terminal display unit provides users with an intuitive display of on-site information, facilitating quick problem location by maintenance personnel.
[0040] After the terminal has undergone the aforementioned series of operations, its internal electronic components and modules will generate a large amount of heat. When operating at low power, heat dissipation can be achieved directly through the heat dissipation holes 401 on the heat sink 40. However, when operating at high power, the heat dissipation holes 401 cannot dissipate heat in time, and the heat will accumulate inside the housing 10. When the accumulated heat reaches a certain temperature, it will be conducted to the inside of the sealing cavity 408 through the heat conduction ribs 4023 in the heat sensing groove 4022, thereby melting the paraffin inside the sealing cavity 408. The paraffin melts into liquid, increasing its volume, which can push the sealing block 407 to move away from the heat sink 40. Through the connecting shaft 406 and the connecting rod 404, the limiting plate 403 is driven to abut against the guide plate 402 on the other side. The thrust generated by the sealing cavities 408 on both sides can cause the guide plates 402 on both sides to move relative to each other, thereby causing the heat sink 407 on both sides to move away from the heat sink 40. The device detaches from the housing 10, opening its internal space and allowing it to directly contact the outside environment, achieving rapid cooling. As the temperature drops, the paraffin inside the sealed cavity 408 gradually solidifies from a molten state due to insufficient temperature. As the paraffin solidifies, its volume shrinks. Since the sealed cavity 408 is sealed, atmospheric pressure causes the sealing block 407 to move towards the heat sink 40. This, in turn, drives the limiting plate 403 to move synchronously via the connecting rod 404 and connecting shaft 406. However, because the two main limiting blocks 4031 limit each other, the two limiting plates 403 do not move. The two guide plates 402 move synchronously inward, causing the two heat sinks 40 to gradually move towards the side closer to the housing 10, resealing the inside of the housing 10. This completes the problem of rapid heat dissipation under high-power operation, and the terminal automatically completes the opening and closing operations throughout the process.
[0041] In summary, this data acquisition terminal, which supports monitoring of new energy sources and distribution transformers, utilizes the guide plate 402 and the limiting plate 403. On one hand, the main limiting block 4031 on the limiting plate 403 mutually limits each other, achieving the desired installation effect. On the other hand, the state of the paraffin wax senses the internal temperature of the housing 10, automatically and rapidly dissipating heat to prevent excessive heat buildup and ensure the normal operation of internal electronic components. The heat dissipation holes 401 allow heat generated by these electronic components to be promptly expelled from the housing 10 during normal operation, reducing internal temperature and preventing overheating damage or performance degradation. By highly integrating new energy power generation monitoring and distribution transformer monitoring functions, the intelligent management level of new energy power generation equipment and distribution transformers is improved, reducing operation and maintenance costs. Real-time monitoring and early warning mechanisms effectively prevent faults, improving the reliability and safety of power grid operation. Data-driven decision support provides a scientific basis for optimized power system scheduling. The modular design facilitates maintenance and upgrades, enhancing the equipment's scalability and adaptability. Integrating solar panels into the housing enables the data acquisition terminal to achieve self-sufficient energy supply. This not only reduces reliance on the traditional power grid and lowers operating costs, but also embodies the concept of green and environmentally friendly sustainable development.
