In the current era of large-scale development of photovoltaic power plants, module cracking is becoming a "hidden killer" that threatens the power generation and service life of the power plant. Micro scale internal cracks are difficult to detect with the naked eye, but they continue to damage the PN junction structure of the battery cell, leading to a sharp drop in power generation efficiency and an increase in the risk of hot spots. Traditional manual inspection has low efficiency, high missed detection rate, and is difficult to cover in high-risk scenarios, which can no longer meet the refined operation and maintenance needs of modern power plants. The LXH210 drone EL detector launched by LAILX in Shanghai breaks through the detection bottleneck with hardcore technology and provides efficient, accurate, and safe hidden crack detection solutions for photovoltaic power plants.

The LXH210 is equipped with a professional flight platform and a high-end EL imaging system, achieving full domain intelligent scanning from a "sky perspective". The equipment adopts DJI M350 RTK drone as the carrier, with a single endurance of up to 55 minutes and a maximum distance of 15 kilometers for image transmission. Combined with high-precision GPS route planning, it can independently complete fully automatic inspection of complex terrain power stations. Whether it is undulating mountains, floating water surfaces, high-altitude roofs, or greenhouse photovoltaics, it can flexibly shuttle and completely break free from the constraints of geographical environment on detection.
The core imaging module is equipped with a 37 million pixel imported industrial grade infrared detector, paired with a research grade high-sensitivity CMOS chip and a high transparency infrared lens, with a spatial accuracy of 0.1mm/pixel and 4K ultra high definition imaging, accurately capturing more than ten internal defects such as hidden cracks, broken grids, black hearts, black edges, and virtual soldering. Unique full-time dark light autofocus technology, no need for manual focusing, stable detection on cloudy days, low light, and night. Paired with a 1500V imported programmable power supply, multiple strings can be synchronously powered on at the junction box and string. The built-in temperature control system ensures that the operating temperature remains below 50 ℃ for a long time, ensuring safety and stability.

In terms of efficiency and safety, traditional manual inspection of a 1MW power plant requires a team of 5 people and takes several days, while LXH210 can complete full coverage scanning in just 3 hours, increasing efficiency by more than 20 times. No need for personnel to climb, wade through water, or work at heights, zero risk response to complex scenarios. Each detection image automatically records GPS latitude and longitude, with defect localization accurate to centimeter level. Combined with an AI intelligent diagnostic system, it automatically identifies, labels, and grades defects, and generates professional detection reports with just one click. LXH210 is not only a testing device, but also a core tool for intelligent operation and maintenance of photovoltaic power plants, helping power plants improve power generation revenue, extend service life, and promote the photovoltaic industry towards high efficiency, intelligence, and safety.
