Detailed description of the invention
Water tank relies in cabin the cyclic torque produced that vibrates about water to realize subtracting shaking.Under the effect of wave moment, there is rolling in ship, when wave moment frequency and boats and ships natural frequency close to time, maximum and about 90 ° of the delayed wave moment in ship rolling angle.In like manner, ship rolling drives water vibration generation in cabin to subtract and shakes moment, when ship rolling frequency and water tank natural frequency close to time, the subtracting of water tank generation shakes maximum and about 90 ° of the delayed ship rolling of moment.Above-mentioned physical phenomenon is referred to as double resonance, wave moment, ship rolling angle, subtracts and to shake between moment three equal and opposite in direction direction contrary (resonance point), and now water tank subtracts that to shake moment maximum and reverse with wave moment, and stabilizing efficiency is best.
Jointly control formula controllable passive anti-rolling tank principle of device block diagram as shown in Figure 1, rolling is there is in ship under the effect of wave moment, collect attitude of ship by gyroscope and be transported to controller, after centralized control unit process, export the gentle valve events instruction of water valve, air valve and water valve carry out switch motion then.The head of water that controller collects according to water level detector and the attitude of ship that gyroscope collects, control the action of water valve and air valve.Ship rolling cycle and water tank natural period close to time, what water tank produced subtract shakes the maximum and delayed ship rolling about 90 of moment
o, now water tank subtracts that to shake moment maximum and reverse with wave moment, realizes subtracting shaking function.
Jointly control formula controllable passive anti-rolling tank apparatus structure block diagram as shown in Figure 2, embedded controller adopts industrial control module, and each module is as follows:
Master control CHU module 1 by CAN respectively with communication TEU module 3, operator's compartment human-computer interaction interface HMI9, control box human-computer interaction interface HMI10 with communicate with input/output module FTU2;
TEU module 3 is respectively by RS232(COM4) communicate with gyroscope 11, receive water level detector 12 signal by AI, communicated by LAN and PC network interface;
1 road DO output integrated alerting signal in input/output module FTU module 2,8 road DO control air valve 5 switch by pneumatic control valve block 4,2 road DO participate in the output of blow valve 7, the state that 4 road DO control water valve 6 changes, 12 road DI gather air valve 5 by travel switch and close and to put in place signal, and 4 road DI receive blow valve 7 on off states and to put in place signal, and 2 road DI receive high water-level alarm signals, 1 road DI receives air pressure low alerting signal, and 4 road DI gather water valve 6 switches and to put in place signal.
The command signal that pneumatic control valve block 4 exports according to input/output module FTU module 2 in control system, drives air valve action, is that pneumatic system core controls valve member.When real-time participation controls, air valve cylinder two chamber exhaust immediately after the action of air valve 5 On/Off, to ensure the rapidity of action next time, also to make in air valve course of action top pressure in cylinder be significantly less than system working pressure, to realize solar term noise reduction object simultaneously.
Gyroscope 11 signal and water level detector 12 signal is gathered by TEU module 3, be sent to master control CHU module 1, control software design is utilized to obtain average period, head of water etc., and control command is sent to FTU module 2 by CAN, air valve, water valve, blow valve is driven to change its state, FTU module 2 receiving condition feedback signal, the signal received is sent to CHU module 1 and processes, and carries out on off state instruction and alarm display by HMI.In addition, HMI can realize optimum configurations, data store and stabilizing efficiency analysis.
The passive water tank of controllable type adapts to the change of ship with factors such as sea situation, loading condition and navigation marine sites by the switch of water adjusting valve, changes the characteristic vibration cycle of water tank, makes it close to ship rolling state.Adapted to the real-time change in ship rolling cycle by the switch of air valve, in adjusting cabin, water is in the phase place of each oscillation period, makes the rolling phase place about 90 always lagging behind ship
o, at utmost play and subtract the ability of shaking.
Jointly control formula antirolling tank and be equipped with water valve and air valve simultaneously, by two kinds of excellent scarce complementations of mode, in medium sea situation, ship rolling controls close to adopting water valve during natural frequency, obtains good stabilizing efficiency with minimum consumption.Under the complicated sea situation of high sea or the long period rolling of boats and ships wide-angle time (due to the speed of a ship or plane, wave to etc. impact) drive air valve participate in control, with the stabilizing efficiency obtained, avoid water valve mode effect decline even increase the defect of shaking.Namely solving pure water valve, to control stabilizing efficiency under complicated sea situation limited, and the problem that effectively control cycle scope is relatively limited, have and solve the phenomenon that pure Air Valve Control energy consumption is large, noise is large.
Changed the characteristic vibration cycle of water tank by water adjusting valve, make it close to ship rolling state; By the phase difference in the switch adjustment cabin of air valve between water concussion and ship rolling.At boats and ships resonance range based on water valve control, realize energy-conservation subtracting and shake, obtain good stabilizing efficiency; The situations such as comparatively strong or boats and ships cycle is longer in ship rolling irregularity Air Valve Control are main, at utmost play and subtract the ability of shaking.This device adopts water valve air valve Collaborative Control to achieve full speed of a ship or plane green energy conservation to subtract and shake, add safety of ship coefficient, facilitate the Digital Control of sway stabilisation system, optimize to subtract and shake facility information interface.Not only promoting the lifting of anti-rolling technology, is also the integrated innovation of an anti-rolling technology, achieves Intelligent Dynamic and subtracts and shake.
