Background Art

[0002] Oil spill information and exhaust emissions from ships passing through the locks are one of the important contents of ship environmental monitoring. Some technical means and measures can be taken to monitor these two aspects.

[0005] 2. Video monitoring: surveillance cameras are installed in the lock area to monitor the water conditions around the ship in real time. Once an oil spill is found, timely measures can be taken to deal with it.

[0006] 3. Alarm system: Install oil pollution monitoring sensors to monitor the oil pollution concentration in the waters around the ship. Once the concentration exceeds the set threshold, the system will send an alarm signal to remind relevant personnel to take measures.
