Description

Technical Field

[0001] This utility model relates to a communication box for a photovoltaic tracking bracket, belonging to the field of photovoltaic equipment technology. Background Technology

[0002] The photovoltaic tracking bracket system is one of the key pieces of equipment for improving the power generation efficiency of photovoltaic power plants. It uses external sensors to adjust the angle of the photovoltaic modules in real time; simultaneously, it triggers protective actions based on meteorological information. The communication box, acting as the "nerve center" of the system, plays a crucial role in enabling centralized monitoring, command issuance, and data acquisition of the entire tracking bracket array.

[0003] However, existing photovoltaic tracking bracket communication boxes have technical problems in terms of power supply and debugging, specifically including: 1. Cost and reliability issues of the power supply system: Existing communication boxes rely on independent external power supplies or complex external power supply schemes, resulting in complex system wiring, high costs, and the external power supply module is prone to failure in harsh outdoor environments, causing power loss of the communication box, tracking system shutdown, inconvenient maintenance, and serious loss of power generation. Before the photovoltaic power station is connected to the grid, there is often no 220V mains power access, and the tracking bracket must be debugged before grid connection. Therefore, most of them currently use external power supply. Since most project sites are remote, it is not possible to carry a large amount of power at one time. During debugging, the power supply often needs to be charged, resulting in low debugging efficiency.

[0004] 2. Convenience issues in on-site debugging and maintenance: Existing communication boxes use traditional industrial serial ports or dedicated debugging terminals. On-site technicians must rely on bulky professional equipment, which is extremely inconvenient and inefficient to operate in narrow spaces. Furthermore, they cannot quickly interface with widely used smart mobile terminals, making it difficult to achieve efficient and agile on-site configuration, program updates, and fault diagnosis.

[0005] To address the aforementioned issues, this application proposes a communication box for a photovoltaic tracking bracket. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the existing defects and provide a communication box for photovoltaic tracking brackets, which has the advantages of convenient debugging and reduced power supply costs, and can effectively solve the problems in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A communication box for a photovoltaic tracking bracket includes a communication box mounted on a weather pole, and further includes: The communication box motherboard is located inside the communication box, and the communication box motherboard integrates a communication module, a microprocessor, and a USB interface controller. The outside of the communication box is provided with a USB physical interface that is electrically connected to the USB interface controller, and the microprocessor integrates a USB interface protocol conversion module; The component power supply module is located inside the communication box and is electrically connected to the communication box motherboard; The photovoltaic modules are installed on the weather pole and connected to the module power supply module via photovoltaic module power supply cables. The module power supply module supplies the DC power generated by the photovoltaic modules to the main board of the communication box.

[0008] As a further improvement of this utility model, a switching power supply is also installed inside the communication box. The input terminal of the switching power supply is connected to a 220V power supply cable through a circuit breaker, and the output terminal of the switching power supply is connected to the main board of the communication box through a wire.

[0009] As a further improvement of this utility model, a battery is also provided inside the communication box, and the battery is connected to the main board of the communication box via wires.

[0010] As a further improvement of this utility model, the component power supply module is connected to the battery via wires to charge the battery.

[0011] As a further improvement of this utility model, the communication box shell is provided with an AC POWER interface and a DC POWER interface, the photovoltaic module power supply cable is connected to the DC POWER interface, and the 220V power supply cable is connected to the AC POWER interface.

[0012] As a further improvement of this utility model, the weather pole is also equipped with a GPS module and a wind speed and direction sensor, and the GPS module and the wind speed and direction sensor are respectively connected to the communication module via data cables.

[0013] As a further improvement of this utility model, a lightning rod is also fixedly installed on the top of the weather pole.

[0014] The beneficial effects of this utility model: A communication box for a photovoltaic tracking bracket has at least one of the following advantages: 1. Regarding economy and system simplification: Reduce system costs: Before the photovoltaic power station is connected to the grid, the communication box can be powered and debugged by the photovoltaic modules. After grid connection, it can be connected to the mains power, which reduces the length of the cables and the costs of cables, pipes and construction, significantly reducing the initial investment of the photovoltaic tracking system.

[0015] Simplified system structure: By using the photovoltaic modules themselves as a power source, energy is "sourced locally," simplifying the system power supply architecture and reducing potential points of failure.

[0016] 2. Regarding reliability and maintainability: Improved power supply reliability: It avoids the risk of damage to independent external power modules in harsh outdoor environments. As long as the photovoltaic modules can generate electricity, the communication box can obtain working power, which greatly reduces the probability of the entire tracking bracket system stopping due to power failure and ensures power generation benefits.

[0017] Enhanced maintenance convenience: The component power supply module is integrated inside the box, with a compact structure. If a fault occurs, it can be replaced or repaired only inside the communication box, without the need to find and replace the external power supply, making the maintenance process simpler and more efficient.

[0018] 3. Regarding on-site commissioning and maintenance efficiency: Greatly improves debugging convenience: The standard USB interface eliminates the need for technicians to carry bulky special debugging tools. They can simply use a universal USB data cable to connect to a laptop or smart mobile device (phone / tablet) to perform their work. The operation is simple, and the connection is fast and reliable.

[0019] Improve the intelligence and efficiency of operation and maintenance: Supports integration with smart mobile terminals, facilitating parameter configuration, status monitoring, fault diagnosis, and program upgrades using customized apps, making on-site operation and maintenance work more agile, intuitive, and efficient, greatly shortening fault handling time, and reducing the technical threshold and labor costs of operation and maintenance.

[0027] The photovoltaic tracking bracket system is one of the key devices for improving the power generation efficiency of photovoltaic power plants. Through external sensors, it adjusts the angle of the photovoltaic modules in real time to ensure that they are always perpendicular to the angle of incidence of sunlight, thereby significantly increasing power generation. At the same time, it triggers protective actions of the bracket based on meteorological information. The communication box, as the "nerve center" of the system, plays a crucial role in realizing centralized monitoring, command issuance, and data acquisition of the entire tracking bracket array. Before the photovoltaic power plant is connected to the grid, there is often no 220V mains power supply. However, the tracking bracket must be debugged before grid connection. Therefore, most systems currently use external power supplies. Since project sites are mostly remote, it is impossible to carry a large number of power supplies at once, especially when traveling by plane or high-speed rail in foreign countries or remote areas. Large quantities or large-capacity power supplies cannot pass security checks. It is also difficult to purchase power supplies near the project site in remote areas or abroad. Therefore, in most cases, a small power supply is carried to power the communication box during debugging. During debugging, the power supply often needs to be charged, but charging can only be done at a location far from the project site with mains power. This back-and-forth process results in low debugging efficiency. In addition, the communication box is far from the monitoring room, which also presents difficulties in local data forwarding and storage.

[0028] like Figures 1-3As shown, a communication box for a photovoltaic tracking bracket is provided. The communication box 1 is installed on the weather pole 2. The communication box main board 11 is located inside the communication box 1. The communication box main board 11 integrates a communication module 111, a microprocessor 112 and a USB interface controller 113. The outside of the communication box 1 is provided with a USB physical interface 14 that is electrically connected to the USB interface controller 113, and the microprocessor 112 integrates a USB interface protocol conversion module; The component power supply module 13 is located inside the communication box 1 and is electrically connected to the communication box motherboard 11; Photovoltaic module 3 is installed on weather pole 2 and connected to module power supply module 13 via photovoltaic module power supply cable 4. The module power supply module 13 supplies the DC power generated by photovoltaic module 3 to the main board 11 of communication box.

[0029] Photovoltaic module 3 is fixedly installed on weather pole 2, facing the sun in an unobstructed direction; the power supply cables are divided into 220V power supply cable 5 and photovoltaic module power supply cable 4. The 220V power supply cable 5 is introduced from an external power source (this external power source is mainly the power supply equipment inside the photovoltaic power station after grid connection, such as energy storage equipment, etc.). The photovoltaic module power supply cable 4 is connected from photovoltaic module 3 to communication box 1, and communication box 1 is fixedly installed on weather pole 2.

[0030] The component power supply module 13 includes a DC-DC voltage conversion circuit and a reverse connection protection circuit. The component power supply module is equipped with an external input terminal (i.e., DC PWOER interface) for directly connecting the photovoltaic power supply cable 4 from the photovoltaic module on or near the tracking bracket. It converts the wide-range, unstable DC power generated by the photovoltaic module 3 into a stable, low-voltage DC power supply (such as 12V or 24V) required by the various circuits inside the communication box 1 (such as the communication box motherboard 11, communication module 111, etc.).

[0031] Preferably, the input terminals of the component power supply module 13 may also be equipped with overvoltage protection devices (such as TVS diodes) and filtering circuits to enhance reliability under severe conditions such as lightning strikes and surges.

[0032] The communication box 1 integrates a USB debugging interface, and the mainboard 11 of the communication box integrates a USB interface controller 113 and a USB physical interface 14 (such as a Type-A, Type-C or Micro-USB physical interface) exposed on the surface of the communication box 1. The USB physical interface 14 is connected to the USB interface controller 113 and the microprocessor 112 of the mainboard 11 of the communication box through a circuit. This design allows technicians to use a common USB data cable to directly connect portable smart devices (such as laptops, smartphones or tablets) to the communication box 1 to realize one or more functions such as power supply, program burning, parameter configuration and fault log reading.

[0033] The communication box 1 has a built-in USB data forwarding and storage function. It can be directly connected to a computer via the external USB physical interface 14 for data forwarding, or directly connected to a USB flash drive for data storage.

[0034] In addition, the USB interface controller can be simulated as a serial port (USB to TTL / serial port function), so that the communication box motherboard 11 can be recognized by smart devices as a virtual serial communication port, which facilitates communication using general serial port debugging tools or dedicated APP.

[0035] Preferably, the communication box 1 can be provided with an opening with a waterproof sealing cover for the USB physical interface 14, for installing the waterproof sealing cover to ensure the protection level of the interface when it is not in use.

[0036] In some alternative embodiments, a switching power supply 12 is also installed inside the communication box 1. The input terminal of the switching power supply 12 is connected to a 220V power supply cable 5 through a circuit breaker 15, and the output terminal of the switching power supply 12 is connected to the main board 11 of the communication box through a wire.

[0037] In some alternative embodiments, a battery 16 is also provided inside the communication box 1, and the battery 16 is connected to the communication box motherboard 11 via wires.

[0038] As a preferred embodiment, the component power supply module 13 connects to the battery 16 via wires to charge the battery 16. By installing the battery 16, the power can be stored during the day and used to power the communication box 1 at night, providing redundant power supply functionality.

[0039] In addition, the communication box 1 is provided with an AC POWER interface and a DC POWER interface. The photovoltaic module power supply cable 4 is connected to the DC POWER interface, and the 220V power supply cable 5 is connected to the AC POWER interface.

[0040] AC POWER and DC POWER are the 220V power supply interface and the photovoltaic module power supply interface, respectively. AC POWER is the main power input interface, used to receive high-voltage AC power from the power station's industrial power distribution system. It is a high-power, high-reliability input channel. DC POWER is the output interface for powering the photovoltaic module 3 on the weather pole 2 and the internal power distribution system. It is used for external photovoltaic panel input and is independently and isolatedly distributed to each core functional module.

[0041] The 220V power supply uses 220V power cable 5, which is introduced into the weather station through the AC POWER interface to supply power to the weather station. The photovoltaic module 3 is powered by photovoltaic module power cable 4, which is introduced into the weather station through the DC POWER interface to supply power to the weather station. After the photovoltaic power station is connected to the grid, when both 220V and photovoltaic panels are powered, the weather station will give priority to using 220V power supply; when 220V is not powered and photovoltaic module 3 is powered, the weather station will seamlessly switch to photovoltaic module 3 for power supply.

[0042] In some optional embodiments, the weather pole 2 is also equipped with a GPS module 6 and a wind speed and direction sensor 7, which are connected to the communication module 111 via data cables.

[0043] In some alternative embodiments, a lightning rod is also fixedly installed on the top of the weather pole 2.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention.

All such changes and modifications fall within the scope of the present invention as claimed.
