With the development of IT and sensor technology, structural health monitoring technology has begun to be applied in fields such as ships and marine engineering. The Hull Stress Monitoring System developed by our company aims to monitor the safety status of operating ships. The purpose is to achieve real-time evaluation of ship structural safety by monitoring the key structural status information of the entire ship in real time, and provide data support for maritime safety operations. The core technologies of this system, including data collection, data preprocessing, yield strength evaluation, fatigue strength evaluation, longitudinal strength evaluation, vibration monitoring, database management, data encryption, AI algorithms, etc., are independently developed. The main components such as fiber optic sensors and collectors are well-known domestic brands such as Donghua and Bai'an, which are not restricted by foreign countries and can provide comprehensive technical services and after-sales support to domestic users. At the same time, this product has the advantages of high monitoring accuracy, high reliability, strong environmental adaptability, and is suitable for long-term real-time monitoring of ship stress status.
