Marine liquid level remote measurement and valve remote control system experimental device and control method thereof

Abstract

The invention discloses a marine liquid level remote measurement and valve remote control system experimental device and a control method thereof. The experiment device comprises a water inlet pump, aliquid level sensor, a left transverse cabin, a water pipe, an electromagnetic valve, ballast tanks, a right transverse cabin, a water outlet pump, a simulation pool and a ballast cabin, wherein thenumber of the ballast tanks is 12, the ballast tanks are divided into No.1 to No.12 ballast tanks, the ballast tanks are symmetrically distributed on the two sides on the whole, the first ballast tankand the second ballast tank are device heeling adjusting main tanks, the length of each of the first and second ballast tanks is designed to be 600 mm, the width of each of the first and second ballast tanks is designed to be 450 mm, the third ballast tank and the fourth ballast tank are device heeling adjusting main tanks, the length of each of the third and fourth ballast tanks is 600 mm, the width of each of the third and fourth ballast tanks is 300 mm, the rest eight ballast tanks are fine adjustment tanks, equal-area design is adopted, and the main tank area is larger than each fine adjustment tank. The invention provides an experimental device capable of simulating an actual ship ballast tank and a valve control method, the external allocation of ballast water is realized, and the balance adjustment time is reduced.

Description

technical field [0001] The invention relates to the technical field of ship ballast tank systems, in particular to an experimental device for a ship-used liquid level remote measurement and valve remote control system and a control method thereof. Background technique [0002] The liquid level remote measurement and valve remote control system are important components of ship automation control. They are mainly used to detect the ship's liquid level and adjust the ballast water in the ballast tank to keep the ship in a stable state. The research on liquid level remote measurement and valve remote control system in our country started late, and there are problems of immature technology. At present, no effective ballast tank experimental device has been designed as the carrier of ballast water regulation. At present, there are many problems in domestic ballast water control devices, such as figure 1 (a) and figure 1 (b) shows two liquid level telemetry devices. figure 1 In ...

AI Technical Summary

Problems solved by technology

figure 1 (b) A two-way axial flow pump is used to adjust the water volume of the balance tank. This system has a simple structure and takes up less space, but the disadvantage is that it requires high performance of the axial flow pump, and the system only involves internal ballast water Mutual adjustment, low heel compensation rate, long time for adjusting balance

[0003] In terms of valve control, since traditional large civil ships generally adopt hydraulic drive, but the use of hydraulic oil to control valves requires an independent hydraulic pump station to provide power, which not only increases the complexity of the system but also increases the production cost. ; and the control signal is transmitted to the valves of each oil circuit through the hydraulic oil, which will cause problems such as slow signal transmission and lagging valve response in long-distance control
