Description

A hardware system for detecting corrosion of coated glass Technical Field

[0001] This application relates to the field of hardware circuit design, and more specifically, to a hardware system for detecting corrosion of coated glass. Background Technology

[0002] Currently, with the rapid development of building energy conservation, intelligent transportation, and high-end electronic displays, coated glass, due to its excellent optical, thermal, and electrical properties, has been widely used in building curtain walls, automotive glass, photovoltaic modules, and touch panels. Common coated glasses include low-emissivity (Low-E) glass, heat-reflective glass, conductive coated glass (such as ITO glass), and self-cleaning glass. Although the coating layers on the surfaces of these functional glasses have good weather resistance and stability, they may still undergo chemical corrosion, coating peeling, or performance degradation due to environmental factors (such as acid rain, salt spray, high temperature and humidity, and ultraviolet radiation) during long-term use, thus affecting their functionality and safety.

[0003] Currently, the detection of corrosion on coated glass mainly relies on laboratory-level offline testing methods. For example, Taber abrasion tests are conducted according to the national standard GB / T23988-2023 "Test Method for Abrasion Resistance of Coated Glass," or salt spray test chambers (such as GB / T10125-2021) are used to simulate a corrosive environment. In addition, optical properties, film thickness gauges, and adhesion testers are used to evaluate these methods. While these methods can effectively reflect the overall performance of the coating, they generally suffer from long testing cycles, expensive equipment, and the inability to achieve real-time monitoring. Furthermore, they are mostly suitable for quality control before finished products leave the factory and cannot meet the needs for in-situ, dynamic, and long-term corrosion monitoring of coated glass in service.

[0004] Especially in complex environments, such as coastal areas with high salt spray, industrial pollution zones, or extreme climates, the corrosion process of coated glass exhibits gradual and localized characteristics. Traditional sampling inspection methods are prone to missing early signs of corrosion, leading to delayed maintenance and, in severe cases, potential safety hazards or reduced energy efficiency. Although some studies have attempted to introduce sensor technology to monitor environmental parameters of the glass surface (such as humidity and pH), these methods mostly remain at the level of indirect inference, lacking the ability to directly perceive the intrinsic corrosion behavior of the coating layer. Furthermore, they have not developed a systematic hardware architecture and circuit layout scheme, making it impossible to achieve quantitative identification and spatial localization of corrosion levels.

[0005] On the other hand, existing corrosion detection devices are typically large, fixed equipment that lacks integration, miniaturization, and embeddable design features, making it difficult to adapt to coated glass with different curvatures, thicknesses, and application scenarios. Furthermore, in terms of circuit design, there is a lack of low-noise acquisition, anti-interference transmission, and low-power operation mechanisms for weak sensor signals, resulting in poor monitoring system stability, high energy consumption, and difficulty in achieving long-term unattended operation.
