Technical Field
The invention relates to the technical field of ship ballast tank systems, in particular to an experimental device for a marine liquid level remote measurement and valve remote control system and a control method thereof.
Background
The liquid level remote measuring and valve remote control system is an important component of ship automation control, and is mainly used for detecting the liquid level of a ship and adjusting ballast water in a ballast tank to keep the balance of the ship to achieve a stable running state. The research on the liquid level remote measurement and valve remote control system in China is late, the problem of immature technology exists, and an effective ballast tank experimental device is not designed as a carrier for regulating and controlling ballast water at present. At present, there are many problems in domestic ballast water regulation and control devices, and two kinds of liquid level telemetering devices are shown in fig. 1(a) and fig. 1 (b). In fig. 1(a), the ballast water is mainly regulated by a one-way water pump and a group of valves, and the valves are impacted and have high failure rate because the states of the valves and the water pump are frequently switched during operation. The system only uses one water pump, and if the system fails, the whole system fails. The water quantity of the balance water tank is adjusted by adopting a bidirectional running axial flow water pump in the figure 1(b), the system has a simple structure and small occupied space, but the defects are that the requirement on the performance of the axial flow water pump is high, the system only relates to the mutual adjustment and allocation of internal ballast water, the heeling compensation rate is low, and the adjustment and balance time is long.
In the aspect of valve control, because a hydraulic driving mode is generally adopted in a traditional large civil ship, but an independent hydraulic pump station is required to be arranged for providing power for controlling the valve by adopting hydraulic oil, the complexity of a system is increased, and the production cost is also increased; and control signals are transmitted to valves of all oil paths through hydraulic oil, and the problems of slow signal transmission and delayed valve reaction can be caused in long-distance control.
