Problems solved by technology
[0002] At present, the disadvantage of the water ingress alarm device in the cargo hold is that, because there is no bus system for interconnection, each water level detector and repeater is connected to the monitor through a cable, and the wiring is complicated and the wiring cost is high; the water level The monitoring uses switch value detectors, and each cargo hold needs to use two water level detectors, and the system cannot monitor the specific water level
The alarm display uses square LED indicator lights to indicate the water ingress alarm and pre-alarm information of each cabin. The more cargo holds, the more indicator lights are used, the reliability is low, and the system scalability is poor.
