Drone el detector

1. Product introduction of UAV EL detector

The UAV EL detector is also called the photovoltaic power station UAV EL tester equipment. The UAV EL detector is used for quality inspection of internal defects in the square array components EL of the photovoltaic power station. This system can quickly and efficiently complete the quality inspection of the photovoltaic power station. It can also switch between photo mode and video mode for third-party operation and maintenance quality inspection. With fully automatic focus, it can switch between multiple modes of detection functions, making it the preferred equipment for power station inspection and operation and maintenance inspection.

This device uses an (M300 RTK) drone with a single flight life of up to 55 minutes, providing a stable and reliable high-performance flight platform for third-party industry drone applications. Up to 3 hours of EL crack inspection of MW-level photovoltaic power stations allows workers to say goodbye to tedious and repetitive low-value labor, greatly improving work efficiency. With the help of drone technology, the electrosurgical work automation process can be realized, effectively reducing operation and maintenance costs. , and at the same time, it can act as an agent for personnel to perform operations in high-altitude and high-risk environments, making EL testing safer.

5. Advantages of UAV EL detector products

1. Advantages of drones

M300 PTK has long-lasting battery life, safety and reliability

This equipment uses the (M300) top drone. As a top drone manufacturer, the M300 RTK has higher flight stability and reliability. The lightweight design of the M300 can be equipped with an all-weather large-load movable knife system. It has a long battery life of up to 55 minutes and relies on the new OcuSync industry version image transmission system, which brings a control distance of up to 15 kilometers and three-channel 1080P high-definition image transmission. The drone is equipped with 2.4/5.8GHz dual-channel communication, which can automatically switch to the best channel in real time during the inspection process. It can still effectively resist interference in complex environments. It is equipped with AES-256 image transmission encryption technology to always ensure the security of data transmission. , supports LTE backup link, further improving the reliability of image transmission. The entire system has higher performance stability.

Efficient and professional all-in-one aerial photography solution

The M300 UAV adopts a modular design. The efficient knife system integrates dustproof, waterproof, and active cooling functions, and provides a maximum wind resistance of 15 meters/second. When equipped with the UAV EL detection gimbal camera, it can provide Up to 50 minutes of battery life detection and 45 minutes of hover monitoring. It only takes 40 minutes to fully charge a single battery pack, and three battery packs can achieve uninterrupted EL inspection and testing of photovoltaic power stations.

2. Advantages of EL inspection

15KM GPS inspection flight

The device provides ultra-long battery life and long-distance real-time battery life detection with a maximum range of 15 kilometers. At the same time, the high-precision GPS route planning function, combined with a fully automatic optical zoom camera, makes unmanned intelligent inspection of photovoltaic power stations possible.

3. High-power imported EL power supply string supply

The EL string power supply is the core equipment of the entire system. It not only determines the image clarity but is also an indispensable link for efficient EL inspection.

The power supply system of this equipment can perform multi-string EL power-on testing at the inverter/junction box. The power supply has a built-in programmable temperature control system to ensure that the temperature of the power supply is below the safe range of 50°C for a long time. At the same time, the digital control panel greatly reduces the risk of personnel contact and can better ensure the safe use of operators.

4. Advantages of EL camera

50Hz high frequency imaging

The El camera equipped on this device uses German high-frequency InGaAs infrared chip and has a more excellent infrared sensor, which provides hardware guarantee for the clear image quality of EL detection. High-frequency imaging technology can provide clear and thorough dynamic videos and aerial pictures of internal defects in photovoltaic modules while the drone is flying.

Full-time autofocus in low light

An accurate focus system is the core requirement of EL imaging, which determines whether the image is clear or not. The EL camera of this device relies on the independently developed infrared lock-in focus system, which allows the device to perform real-time fully automatic zooming during drone inspections. , making UAV EL aerial photography inspection free from the troubles of follow focus and fixed-point flying.

5. Software advantages

Video processing software

For drone video inspection mode, the EL camera can save a variety of optional video formats, and the software can enhance the video quality and extract single-frame images to facilitate user report organization and analysis.

Image processing software

For drone hovering photography mode, the EL camera can take multiple continuous shots and save multiple EL imaging images at the same time, which can be synthesized through software to generate clearer pictures of internal defects in components.

Cloud management system (optional)

Our online cloud system has functions such as picture storage, data storage, power station operation and maintenance data management, power station inspection report generation and export, automatic identification, power station information management, power generation evaluation and PR system efficiency value calculation.

Automatic defect identification (optional)

EL automatic identification software relies on the online cloud processing system. Users can independently learn AI recognition and generate exclusive identification modules. They can also choose existing identification modules to identify internal defects in photovoltaic modules. The identification types include fragments, fragments, cracks, and short circuits. , attenuation, etc.
