Abstract
Ultrasonic sensors, characterized by their non-contact nature, high precision, and strong adaptability, play a significant role in industrial automation inspection. This study aims to enhance the detection performance of ultrasonic sensors in complex industrial environments by addressing issues such as strong signal interference, low data processing efficiency, and insufficient detection accuracy that exist in traditional methods. By integrating advanced signal processing algorithms with optimized hardware design, the research improves signal quality through the introduction of adaptive filtering technology and employs machine learning models for intelligent analysis of detection data, thereby significantly increasing the accuracy and stability of the detection system. Experimental results demonstrate that the optimized ultrasonic sensor system exhibits superior performance in terms of target recognition rate, anti-interference capability, and real-time performance, with a detection accuracy improvement of approximately 20% over conventional methods in typical applications such as me tal surface defect detection and liquid interface measurement. Furthermore, this study proposes a collaborative detection scheme based on multi-sensor fusion, which enhances the robustness of the system. Overall, this research not only provides new technical approaches for the practical application of ultrasonic sensors but also lays a theoretical foundation for their intelligent upgrade in the context of Industry 4.0, holding important academic significance and engineering value.
