The digital measurement and control system based on waterway can effectively enhance and improve the scientific level of waterway engineering management and safe transportation. It is widely used in inland waterways such as large rivers and seaways. Digital waterway monitoring is a digitalized, networked and intelligent technology system integrating remote sensing, telemetering, geographic information system, broadband network, communication, computer vision and multimedia technologies. It is also an integration of information infrastructure and information system, and a network image monitoring system using microwave/optical fiber communication technology, digital video processing technology and other advanced communication technologies, in which the sensor plays a decisive role. The array composed of Guochuang micro-magnetic basic sensors is adopted to monitor the magnetic anomaly of the waterway, monitor the traffic of ships in real time, and feed back to the maritime management department in time to facilitate unified dispatching management. Once the micro-magnetic basic sensor array detects the waterway magnetic anomaly signal, the model algorithm will be used to analyze it, and it can also determine whether there is geological anomaly (such as earthquake, etc.) in or near the waterway, and issue an early warning message to warn passing ships to modify the route, or suspend navigation to ensure the safety of passing ships.

Guochuang micro-magnetic basic sensor can be used for 24-hour remote monitoring under various adverse weather and geographical environment conditions, recording in real time the on-site conditions of the waterway, timely detecting navigation beacon status, ship navigation status, illegal sand mining, water occupation, etc., and providing good prediction, alarm, management and other services for the smoothness and safety monitoring of the waterway. Furthermore, it can be used for remote emergency command for emergencies in the waterway. At the same time, it can be effectively linked to the environmental monitoring equipment and systems to obtain the relevant pollution indicators and form unified data backup with video, providing decision-making and law enforcement basis for the sea, maritime, waterway management, water department, water transport department, flood control and drought relief as well as "three defenses" emergency command departments.
