【Specific embodiment】

In order that the object, technical solutions and advantages of the present invention are clearer, with reference to the accompanying drawings and detailed description The present invention will be described in detail.

When the power that marine main engine is produced is constant, the speed of ship depends on the resistance suffered by its own.When ship is in stream When being navigated by water in water, as long as the speed through water of ship is equal to the speed navigated by water in hydrostatic, suffered resistance is minimum.

One ship travels a round voyage from A points to B points, and resistance can be subject to during shipping agency enters.Wherein, water resistance, wind Resistance is the main resistance being subject to during shipping agency enters.

Water resistance suffered by one ship is relevant with the relative velocity of ship and water, also relevant with catchment area；Suffered Wind resistance is relevant with the relative velocity of ship and wind, also relevant with wind area.For a ship, its catchment area and wind-engaging Area is definite value.According to resistance operational formula：

F=c*s*v²

The water resistance and wind resistance suffered by ship can be calculated；C is ship to water or the resistance coefficient to wind in formula；s It is that hull receives water or wind area, is also constant, v is ship to water or the relative velocity to wind.

Under hydrostatic model, water is hydrostatic, i.e., the absolute velocity of water is 0；Wind is calm, i.e., wind scale is 0.Then basis Formula：F=(c*s+c ' * s ') * v²Resistance suffered by ship can be calculated.

Wherein, c is resistance coefficient of the ship to water in formula, c ' be ship to wind resistance coefficient, be constant；S is that hull is received Water area, s ' is the wind area of hull, is also constant, v be ship to water or the relative velocity to wind, be also herein over the ground Absolute velocity.

At this moment resistance acting：W=f*L, L represent the distance of ship's navigation.

According to the computing formula of above-mentioned resistance, it is known that under hydrostatic model, acceleration will increase resistance, deceleration can reduce Resistance.

In the case of flowing water, there is current absolute velocity v_Water.Assuming that water velocity is in the first half distance and ship navigation direction It is identical, it is in opposite direction in later half distance and ship navigation, and water velocity size is constant.The ground speed of ship round voyage is V. Then the resistance in the first half distance does work and is：

w_o1=c*s*L/2* (v-v_Water)², c is ship to water imprint in formula, and s is catchment area.In latter midway Resistance in journey does work and is：

w_o2=c*s*L/2* (v+v_Water)², in the case where windage is not considered, drag overall acting is：

W=w_o1+w_o2,

In this case, we adjust the gait of march of ship, and specific method is acceleration Δ v when downstream, when against the current Deceleration Δ v.After do so, then the resistance acting in the first half distance is：

w’_o1=c*s*L/2* (v-v_Water+Δv)²,

Resistance in later half distance does work and is：

w’_o2=c*s*L/2* (v+v_Water-Δv)²,

Drag overall is done work：

W '=w '_o1+w’_o2

We use w ' and w to subtract each other, and are obtained after arrangement：

Δ w=c*s*L/2* (2* (Δ v)²-4*v_Water* Δ v),

This is a quadratic function, and secondary term coefficient is more than 0, so there is minimum.Δ w after deformation by obtaining

So working as Δ v=v_WaterWhen Δ w minimalizations be：

The percentage of reduction is：

On this basis, we consider further that windage is done work, it will be assumed that round voyage navigation apoplexy direction all the time not Become and size is also constant, so wind can be along navigation direction, it is also possible to against navigation direction.Windage acting can be represented For:

w₃=c ' * s ' * L* (v ± v_Wind)², c' in formula is ship to wind resistance coefficient, and s' is wind area.

So at this moment drag overall acting is：

W=w_o1+w_o2+w₃, it is therein+to represent against the wind ,-represent with the wind.

In this case, we adjust the gait of march of ship, and specific method is acceleration Δ v when downstream, when against the current Deceleration Δ v.In addition to changing water resistance and doing work, windage acting is in round voyage：

w’₃=c ' * s ' * L/2* ((v+ Δs v ± v_Wind)²+(v-Δv±v_Wind)²), drag overall acting is：

W '=w '_o1+w’_o2+w’₃, we use w ' and w to subtract each other, are obtained after arrangement：

This is one two Secondary function, and secondary term coefficient is more than 0, so there is minimum.Δ w after deformation by obtaining

So working asWhen Δ w minimalizations be：

The percentage of reduction is：

The engine speed of determining of prior art navigates by water (being that ship determines ship's speed navigation to water), is not considering the influence of wind Under, marine main engine selectes an experience rotating speed.This experience rotating speed just has a ship's speed for stabilization in hydrostatic.When ship runs into During following current, due to the drag reduction that ship is subject to, ship's speed is accelerated；When adverse current is run into, because the resistance that ship is subject to increases, ship Speed slows down.

At this moment when ship adds water velocity in the speed of the ship in metres per second that the absolute velocity of first half term is equal under the rotating speed, in the second half Absolute velocity be equal to speed of the ship in metres per second under the rotating speed when subtracting water velocity, ship is minimum in the resistance that round voyage is subject to.

F is the power of main frame, is a definite value, and f is resistance, and m is ship gross mass,It is acceleration.

However, because the gross mass of ship is big, inertia is just big, in following current because resistance is relatively smaller, so With regard to very little, and because the quickening of ship's speed, resistance are also increased by, acceleration just diminishes the acceleration of ship, so accelerator It is just long, can be drawn from theoretical calculation, as shown in figure 1, needing infinite time when accelerating to speed increase value equal to water speed.

When water flow variation is run into, i.e., by being transformed into downstream when against the current, ship is due to the presence of inertia, although ship is subtracting Speed, because deceleration is smaller, ship is reduced to the speed under experience rotating speed from original speed, then reduces again, and reduced value is 2 V again_Water, it is necessary to long time.

Therefore, although using rotating speed navigation is determined, can theoretically save oil consumption, but actually due to ship acceleration and deceleration Process is very long, and influence change of the water to ship is very fast during Hainan Airlines in addition, so energy-saving effect is very little.To reach preferably section Energy effect, it is necessary to artificial interference, i.e., when water (flow) direction is judged, actively increase or actively reduce the rotating speed of marine main engine, The absolute velocity of ship is set to meet requirement.

If it is considered that the influence of wind, situation is just more complicated.Increasing or decreasing for ship's speed is relevant with water velocity, and with Ship selected velocity is relevant, also with to wind coefficient and to water coefficient, relevant by water and wind area.But it is one to increase or decrease value Individual definite value.

Similarly, since the gross mass of ship is big, realize accelerating certain value or deceleration certain value by the change of resistance, need Wanting long time could realize.It is also required to human intervention.

Equally, the main engine power of determining of prior art is navigated by water, and is also rule of thumb, to determine a main engine power.In the main frame Under power, ship can have a speed for stabilization in hydrostatic.When ship's navigation is in flowing water, and when determining engine speed situation The variation tendency of acceleration be the same.And in the case of wind very little, velocity variable is equal to v_WaterWhen, suffered by ship Drag overall is minimum.

In the case where wind speed is not considered, as the absolute velocity of ship's navigation is with situation when determining rotating speed, i.e., following current when ship The absolute velocity of oceangoing ship is speed of the ship in metres per second under the rotating speed plus water velocity, the ship under the absolute velocity of the reverse-flow ship rotating speed When oceangoing ship speed subtracts water velocity, the resistance suffered by ship is minimum.

The power of marine main engine is P₀, according to acceleration equationWherein f is resistance, and m is the total matter of ship Amount,It is acceleration.

With determine engine speed navigate by water when acceleration change it is similar, ship determine main engine power navigation when, acceleration with Hours underway is less and less.And can be drawn from theoretical calculation, as shown in Fig. 2 when accelerating to speed increase value equal to water speed Need infinite time.And, during being changed from boost phase to the decelerating phase, ship needs the ship's speed from after acceleration first to subtract Speed is to after the ship's speed in hydrostatic, then reduces.Time so can be longer.If it is considered that the influence of wind, and determine engine speed boat The same during row, situation equally becomes very complicated, but acceleration equationIt is not changed in, simply the table of resistance f Become increasingly complex up to formula.Drawn from situation analysis above：When ship is navigated by water in flowing water, as long as speed through water of ship etc. When the speed navigated by water in hydrostatic, suffered resistance is minimum.Also, either determine engine speed navigation and still determine main engine power Navigation, can not all make the response speed of ship reach requirement, therefore, in the present invention, proposition actively adjusts shipping sail speed Control method and device, it is possible to achieve more excellent ship energy saving navigation so that oil consumption is smaller during ship's navigation, and cost is lower, Pollution is less.As shown in figure 3, in first embodiment of the invention, the control method of the ship energy saving navigation includes：

Configure the default instantaneous fuel delivery of a marine main engine；

Usually, marine main engine uses low speed high output diesel engine, and the fuel system of Diesel engine is note Combustion chamber oiling from oil pump to Diesel engine.Filling pump is by the week time to the injection flow of combustion chamber in a period of time What accelerator open degree and engine speed under the phase were determined.For example, main frame every revolution is to drive filling pump to the pump of note in combustion chamber one Oil, and determined by accelerator open degree at least to many of the pump oil of combustion chamber note one.

In the present embodiment, control device in order to accurately control to combustion chamber injection flow (marine main engine Instantaneous fuel delivery), current instantaneous fuel delivery can be monitored by fuel contents gauge, but for the more stable instantaneous fuel delivery of control, this Implementation method also using accelerator open degree, the relation of engine speed and instantaneous fuel delivery, by the current fuel delivery to main frame (i.e. Instantaneous fuel delivery) value be defined as current throttle opening value * current hosts tachometer values, to facilitate calculating.

In this way, can be set as that one is determined by by the result of product of current throttle opening value and current hosts tachometer value Value, and cause ship by controlling accelerator open degree (being bigger accelerator open degree, the injection flow of each pump is more, and engine speed is faster) Oceangoing ship main frame remains that the default instantaneous fuel delivery is constant, meanwhile, also can search out phase beneficial to accelerator open degree and engine speed To equalization point.

Ship is generally required by leaving the port, approach during going to sea, and road is driven towards sea route and waited along the river Journey, and the control method in present embodiment, focus mainly on control when ship at sea carries out routinely navigating by water, and described is normal The speed of a ship or plane that rule navigation refers to ship can be only as suffered by the performance and ship of marine main engine resistance (including the resistance of wind, water Resistance etc.) determined, and regardless of other artificial disturbance factors, such as traffic rules, navigation principle etc..Conventional navigation one As be also that in Hainan Airlines, ship keeps the operational configuration to navigate by water a kind of farthest navigation mode of distance.

It should be noted that：Above-mentioned instantaneous fuel delivery and the concept of conventional navigation can equally be well applied to other realities of the invention Apply mode.

When riding the sea, situation about being run into is Protean, in real navigation, due to tide and the pass of monsoon System, ship can not possibly adverse current or following current always.Present embodiment passes through instantaneous fuel delivery of the control to marine main engine, to cause ship Oceangoing ship main frame is navigated by water regardless of extraneous resistance with this instantaneous fuel delivery, is the surely instantaneous fuel delivery fortune of marine main engine OK.

In this way, in the present embodiment, in the case of the load on host computers increase of ship, current throttle aperture can be increased to New equalization point is reached with current hosts rotating speed to be run；In the case of the load on host computers of ship reduces, current throttle can be opened Degree is decreased to be run with the current hosts rotating speed new equalization point of arrival.

The control method of present embodiment, determines engine speed or determines main engine power navigation relative to traditional, can be covert According to outside to the resistance of ship, the change of active control marine main engine operational factor.

It is appreciated that when the resistance of outer bound pair ship diminishes (such as following current), correspondingly, what the propeller of ship was subject to Resistance diminishes (such as power-assisted can be subject to during following current), causes the load of main frame to diminish, under identical instantaneous fuel delivery, engine speed Accelerate, acting becomes many, speed of the ship in metres per second accelerates (raised speed equivalent to active)；When the resistance of outer bound pair ship becomes big (such as adverse current) When, correspondingly, the resistance that the propeller of ship is subject to becomes big, and the load of main frame becomes big, and under identical instantaneous fuel delivery, main frame turns Speed is slack-off, and acting tails off, and speed of the ship in metres per second is slack-off therewith (slowing down equivalent to active).According to above-mentioned theoretical foundation, this embodiment party The marine main engine of formula navigates by water and determines main engine power navigation relative to traditional engine speed of determining, and it can improve ship and resistance is changed Response speed afterwards, Δ w numerical value is quickly diminished so that ship's navigation reaches more preferable oil-saving effect.

Same ship on the premise of load-carrying is the same, by real navigation (from PORT OF CHANGSHU to PORT OF QINHUANGDAO, it is allowed to when navigating by water Between be 55 hours) the multiple test probability of accident (reduce), when being navigated by water by the control method of present embodiment, per single Few 2~3 tons of the oil consumption that the oil consumption of journey is navigated by water than constant speed, with the 4300 yuans of conversions of in the market heavy oil per ton, a ship list Journey can save 8600~12900 yuans, greatly reduce energy resource consumption, save navigation cost.

Further, in the present embodiment, the default instantaneous fuel delivery can be set by navigating by water the experience of accumulation, Can be calculated by following scheme and set and described preset instantaneous fuel delivery.

For example, can be according to navigation distance and permission hours underway most long, calculating navigation allows most jogging speed；And according to navigation The load on host computers for allowing most jogging speed and ship to be navigated by water in hydrostatic, calculates required instantaneous fuel delivery, as default wink When fuel delivery.Usually, in ship's navigation, can be one from the hours underway for being spent of origin-to-destination can allow fluctuation Interval, such as hours underway from PORT OF CHANGSHU to PORT OF QINHUANGDAO can be now most long to allow navigation in 50 hours to 55 hours Time is 55 hours.So, you can according to navigation distance and most it is long allow hours underway calculate navigation permission most at a slow speed Degree.It is as mentioned above, during Hainan Airlines, it is impossible to always adverse current or following current, therefore the master navigated by water in hydrostatic with ship Machine load is obtained and presets instantaneous fuel delivery as with reference to being calculated.The manner, can because using permission hours underway most long Find the default instantaneous fuel delivery of minimum.

Again for example, the instantaneous fuel delivery of the marine main engine can be gradually changed, boat under each instantaneous fuel delivery is calculated respectively Oil consumption corresponding to the predetermined distance of row；And the minimum instantaneous fuel delivery of the predetermined distance oil consumption of navigation is calculated, as default wink When fuel delivery.In this programme, the instantaneous fuel delivery of the marine main engine can be gradually changed after ship starts navigation, also may be used After ship enters conventional navigation, then the instantaneous fuel delivery of the marine main engine is gradually changed, and can be according to each instantaneous confession The speed of a ship or plane tended towards stability under oil mass is (because, it is necessary to by a time delay, could reflect to ship after ship changes instantaneous fuel delivery On the headway of oceangoing ship, and in water, headway is more difficult accurately to be rested in a value, can only tend towards stability), calculate Navigate by water the oil consumption corresponding to predetermined distance (such as 100 nautical miles).So, after multiple instantaneous fuel deliveries were attempted, you can find out boat The minimum instantaneous fuel delivery of the predetermined distance oil consumption of row.Certainly, in the manner, can often by a cycle (usually 15 minutes) Change the instantaneous fuel delivery of the marine main engine once, to allow the instantaneous fuel delivery after changing to be reflected into the navigation speed of ship On degree.Such scheme, more intelligent can search out suitable ship and preferably presets instantaneous fuel delivery.

Certainly, before the instantaneous fuel delivery for gradually changing the marine main engine, also can first using it is above-mentioned it is calculated most Small default instantaneous fuel delivery is navigated by water.

Further, the main frame of general ship has the security interval that it runs, and excessively slow engine speed can cause ship Main shut-down system；Too fast engine speed can then cause marine main engine detonation.In addition, Diesel engine engine speed characteristic (rotating speed It is in cube relation with oil consumption) show, air inlet gas flow rate is slow during main frame low speed, and fuel-oil atmozation is bad, and thermal loss is more, oil consumption It is high；Mechanical loss is big during main frame rotating speed high, and oil consumption is also big, so oil consumption all can accordingly increase when engine speed is too high or too low Greatly, there is a preferable economic speed so in the range of engine speed.

Cause marine main engine to run beyond the security interval to avoid the instantaneous fuel delivery of above-mentioned change, or keep ship master Machine is operated in the interval of economic speed, can configure the higher limit and lower limit of the marine main engine rotating speed.In this way, can be by control Accelerator open degree processed controls marine main engine operation in the interval of the higher limit and the lower limit, is the instantaneous of change Fuel delivery also has certain constant interval, and the change of instantaneous fuel delivery can not be turned to and drive marine main engine under the instantaneous fuel delivery by it Revolution exceed the higher limit or less than the lower limit, to ensure the operation safety of marine main engine and/or ensure ship master The economy of machine operation.

As shown in figure 4, in second embodiment of the invention, the control method of the ship energy saving navigation includes：

In routinely navigation, when ship is when suffered resistance changes during navigation, the fortune of the ship is changed accordingly Line parameter；

If resistance suffered by the ship diminishes, the instantaneous fuel feeding to marine main engine is increased by controlling current throttle aperture Amount；

If resistance suffered by the ship becomes big, the instantaneous fuel feeding to marine main engine is reduced by controlling current throttle aperture Amount.

Relative to first embodiment, the more operational factor of the de-regulation marine main engine of active can be more for present embodiment Plus improving the response speed after ship changes to resistance so that ship's navigation reaches the fuel-economizing effect more excellent than first embodiment Really.

Further, resistance change of the ship during navigation can in several ways be judged, such as by passing Sensor etc., can also be changed to resistance by following scheme and judged.

For example, the ground speed and speed through water of the ship can be obtained in real time；And according to the ground speed of the ship Judge whether resistance changes suffered by the ship with the speed through water.In theory, if seawater is static, and the influence without wind Under, the ground speed and speed through water of ship should be identical.However, having current in the seawater and/or existing in the case of having wind When, the ground speed and speed through water of ship then occur difference：When ship following current (including combined influence of current and wind) boat During row, its speed through water is less than ground speed；When ship is sailed against the current, its speed through water is more than ground speed.Wherein, ship Ground speed can be obtained by similar GPS device, the speed through water of ship can be by the respective sensor of the assembling on ship Obtain.It is understood that under same instantaneous fuel delivery, when the ground speed and speed through water of ship change, or It is that resistance suffered by ship changes when speed difference between the ground speed and speed through water of ship changes.

Again for example, the ground speed of the ship can be obtained in real time；If the ground speed of the ship changes, sentence The resistance suffered by the ship that breaks changes.Ginseng described above, it is to be understood that under same instantaneous fuel delivery, ship it is right Ground speed should keep constant, be that resistance changes suffered by ship if changing.What deserves to be explained is, present embodiment In technical scheme be according to external condition, the dynamic control scheme of ship active feedback.It is appreciated that in resistance suffered by ship After change, still may proceed to judge whether the resistance that the resistance that ship is subject to has changed relatively has change again, if changing, phase The operational factor of the adjustment ship answered.In this way, can according to the change of external condition, can constantly active accommodation marine main engine wink When fuel delivery, optimize ship oil consumption.

Further, in the present embodiment, instantaneous fuel delivery can moderately be increased or decreased according to the experience of navigation accumulation, Can also be by the preferred instantaneous fuel delivery after following scheme calculates change.

Further, in the present embodiment, if resistance suffered by the ship diminishes, gradually increase to the ship master The instantaneous fuel delivery of machine, and calculate oil consumption corresponding to predetermined distance is navigated by water under each instantaneous fuel delivery in real time, to find out navigation The minimum preferred instantaneous fuel delivery of predetermined distance oil consumption, and keep the preferably instantaneous fuel delivery to continue to navigate by water, until ship institute Changed by resistance；

If resistance suffered by the ship becomes big, the instantaneous fuel delivery to the marine main engine is gradually reduced, and count in real time Calculate and oil consumption corresponding to predetermined distance is navigated by water under each instantaneous fuel delivery, the preferred wink minimum to find out the predetermined distance oil consumption of navigation When fuel delivery, and keep the preferably instantaneous fuel delivery to continue to navigate by water, until resistance suffered by ship changes.

In this programme, can be according to the speed of a ship or plane tended towards stability under each instantaneous fuel delivery (because changing instantaneous in ship , it is necessary to by a time delay, could reflect onto the headway of ship after fuel delivery, and in water, headway is more difficult Accurately rest in a value, can only tend towards stability), calculate the oil consumption corresponding to the predetermined distance (such as 100 nautical miles) of navigation.This Sample, after multiple instantaneous fuel deliveries were attempted, you can find out the minimum instantaneous fuel delivery of the predetermined distance oil consumption of navigation.Certainly, exist In the manner, the instantaneous fuel delivery that often can change the marine main engine by a cycle (usually 15 minutes) once, to allow Instantaneous fuel delivery after change can be reflected on the headway of ship.Such scheme, can more it is intelligent search out it is suitable Close ship and preferably preset instantaneous fuel delivery.

Cause marine main engine to run beyond the security interval to avoid the instantaneous fuel delivery of above-mentioned change, or keep ship master Machine is operated in the interval of economic speed, can configure the higher limit and lower limit of the marine main engine rotating speed.In this way, can be by control Accelerator open degree processed controls marine main engine operation in the interval of the higher limit and the lower limit, is the instantaneous of change Fuel delivery also has certain constant interval, and the change of instantaneous fuel delivery can not be turned to and drive marine main engine under the instantaneous fuel delivery by it Revolution exceed the higher limit or less than the lower limit, to ensure the operation safety of marine main engine and/or ensure ship master The economy of machine operation.Further, in the present embodiment, before active feedback control vessel motion parameter, can match somebody with somebody in advance Put one and preset instantaneous fuel delivery, and in routinely navigation, by controlling accelerator open degree, keep the marine main engine described default Run under instantaneous fuel delivery, until resistance suffered by the ship changes.

In the present embodiment, the default instantaneous fuel delivery can be set by navigating by water the experience of accumulation, it is also possible to pass through Following scheme is calculated and sets the default instantaneous fuel delivery.

As shown in figure 5, in third embodiment of the invention, the control method of the ship energy saving navigation is implemented with second The difference of mode is, in the present embodiment, only when the variable quantity of resistance suffered by ship is more than or equal to predetermined threshold value, The corresponding operational factor for changing ship.Because during ship's navigation, if frequently there is resistance change, causing to need Frequently to change the operational factor (such as instantaneous fuel delivery) of ship, be detrimental to energy-conservation.

Therefore, in the present embodiment, it is necessary to be pre-configured with a predetermined threshold value, so, only when resistance suffered by ship When variable quantity is more than or equal to predetermined threshold value, just correspondingly change the instantaneous fuel delivery to marine main engine, in this way, can be to the section of ship Can be advantageously.

Further, the variable quantity for calculating suffered resistance can be obtained by sensing device, also can be by the right of the ship The relativeness of ground speed and speed through water, and/or the change of the ground speed of ship reflects the situation of suffered resistance.

As shown in fig. 6, in four embodiment of the invention, the control method of the ship energy saving navigation is real with respect to the 3rd Apply for mode, can only consider the relation between the ground speed of ship and speed through water, with judge ship it is current by resistance Situation, is to judge that ship is presently at following current or adverse current.

Meanwhile, by the difference of the ground speed of ship and speed through water (water poor) size, can determine whether that needs change Become the instantaneous fuel delivery of marine main engine, specifically include：

If the ground speed of the ship is faster than speed through water, and the difference of both speed is more than or equal to preset value, then lead to Cross instantaneous fuel delivery of the control current throttle aperture increase to marine main engine；

If the speed through water of the ship is faster than ground speed, and the difference of both speed is more than or equal to preset value, then lead to Cross instantaneous fuel delivery of the control current throttle aperture reduction to marine main engine.

The navigation tendency chart specifically adopted in actual ship's navigation will be illustrated in following combination Figure 10.

Usually, if the difference of the ground speed of ship and speed through water is more than or equal to 0.5 section (speed unit of navigation) When, then control accelerator open degree to be adjusted the instantaneous fuel delivery of ship.

As shown in fig. 7, in fifth embodiment of the invention, the control method of the ship energy saving navigation is real with respect to the 3rd Apply for mode, can only consider the ground speed of ship, judged with the ground speed by ship ship it is current by resistance Situation, is to judge that ship is presently at following current or adverse current.

Meanwhile, by the variable quantity of the ground speed of ship, can determine whether the instantaneous fuel feeding for needing to change marine main engine Amount, specifically includes：

If the ground speed of the ship becomes big, and when variable quantity is more than or equal to preset value, then by controlling current throttle Aperture increases the instantaneous fuel delivery to marine main engine；

If the ground speed of the ship diminishes, and when variable quantity is more than or equal to preset value, then by controlling current throttle Aperture reduces the instantaneous fuel delivery to marine main engine.

Usually, if the variable quantity of the ground speed of ship is more than or equal to 0.5 section (speed unit of navigation), control Accelerator open degree is adjusted to the instantaneous fuel delivery of ship.

As shown in figure 8, in the 6th implementation method of the invention, relative to above-mentioned implementation method, the institute of present embodiment Focusing on for the control method that ship energy saving is navigated by water is stated, the instantaneous fuel delivery for more optimizing is determined by way of optimizing, and Navigated by water by the preferred instantaneous fuel delivery for calculating, its oil-saving effect for bringing is it will be apparent that present embodiment Control method includes：

The instantaneous fuel delivery of marine main engine is gradually changed, to calculate that navigate by water under each instantaneous fuel delivery predetermined distance institute right respectively The oil consumption answered；

The minimum instantaneous fuel delivery of the predetermined distance oil consumption of navigation is calculated, and is navigated by water with the instantaneous fuel delivery.

In the present embodiment, the instantaneous fuel delivery of the marine main engine can be gradually changed after ship starts navigation, Also after ship enters conventional navigation, then the instantaneous fuel delivery of the marine main engine can be gradually changed, and can be according to each wink When fuel delivery under the speed of a ship or plane that tends towards stability (because, it is necessary to by a time delay, could reflect after ship changes instantaneous fuel delivery Onto the headway of ship, and in water, headway is more difficult accurately to be rested in a value, can only tend towards stability), Calculate the oil consumption corresponding to the predetermined distance (such as 100 nautical miles) of navigation.So, after multiple instantaneous fuel deliveries were attempted, you can look for Go out to navigate by water the minimum instantaneous fuel delivery of predetermined distance oil consumption.Certainly, in the manner, can often by a cycle (usually 15 Minute) the instantaneous fuel delivery of the change marine main engine once, ship can be reflected into the instantaneous fuel delivery allowed after change On headway.Such scheme, more intelligent can search out suitable ship and preferably presets instantaneous fuel delivery.

Cause marine main engine to run beyond the security interval to avoid the instantaneous fuel delivery of above-mentioned change, or keep ship master Machine is operated in the interval of economic speed, can configure the higher limit and lower limit of the marine main engine rotating speed.In this way, can be by control Accelerator open degree processed controls marine main engine operation in the interval of the higher limit and the lower limit, is the instantaneous of change Fuel delivery also has certain constant interval, and the change of instantaneous fuel delivery can not be turned to and drive marine main engine under the instantaneous fuel delivery by it Revolution exceed the higher limit or less than the lower limit, to ensure the operation safety of marine main engine and/or ensure ship master The economy of machine operation.Further, the second to the 5th implementation method can be joined, to judge properly needing to adjust marine main engine Instantaneous fuel delivery.Will not be repeated here.

As shown in figure 9, in an embodiment of the present invention, the control device that the ship energy saving is navigated by water is applicable to above-mentioned First embodiment is to the 6th implementation method.Control module 200 as described below can control accelerator open degree, to adjust the ship The instantaneous fuel delivery of main frame.

The application is clear succinct in order to describe, and use only a width accompanying drawing.Certainly, in corresponding implementation method and it is not used The module for arriving, can remove from this control device, for example, during correspondence first embodiment, this control device can be only included matches somebody with somebody Put module 100, control module 200, and computing module 300.And so on.

Wherein, when the control device of ship energy saving navigation corresponds to above-mentioned first embodiment, described device bag Include：

Configuration module 100, the default instantaneous fuel delivery for configuring a marine main engine；

Control module 200, in routinely navigation, by controlling current throttle aperture, making the marine main engine all the time Keep the default instantaneous fuel delivery constant.

In the present embodiment, control device in order to accurately control to combustion chamber injection flow (marine main engine Instantaneous fuel delivery), current instantaneous fuel delivery can be monitored by fuel contents gauge, but for the more stable instantaneous fuel delivery of control, profit In control, present embodiment also using accelerator open degree, the relation of engine speed and instantaneous fuel delivery, by current to main frame The value of fuel delivery (i.e. instantaneous fuel delivery) is defined as current throttle opening value * current hosts tachometer values, to facilitate calculating.

Ship is generally required by leaving the port, approach during going to sea, and road is driven towards sea route and waited along the river Journey, and the control method in present embodiment, mainly focus on control when ship at sea carries out routinely navigating by water, described Conventional navigation refers to resistance (including the resistance of wind, water of the speed of a ship or plane of ship only as suffered by the performance and ship of marine main engine Resistance etc.) determined, and regardless of other disturbing factors, such as traffic rules, navigation principle etc..Conventional navigation is general It is that in Hainan Airlines, ship keeps the operational configuration to navigate by water a kind of farthest navigation mode of distance.When riding the sea, run into Situation is Protean, and in real navigation, due to tide and the relation of monsoon, ship can not possibly adverse current or following current always.This Implementation method by control to marine main engine instantaneous fuel delivery, to cause marine main engine regardless of extraneous resistance, with This instantaneous fuel delivery is navigated by water, and is the surely instantaneous fuel delivery operation of marine main engine.

In this way, in the present embodiment, the control module is additionally operable to：In the case of the load on host computers increase of ship, can Current throttle aperture is increased to and is run with the current hosts rotating speed new equalization point of arrival；Reduce feelings in the load on host computers of ship Under condition, current throttle aperture can be decreased to be run with the current hosts rotating speed new equalization point of arrival.

It is appreciated that when the resistance of outer bound pair ship diminishes (such as following current), correspondingly, what the propeller of ship was subject to Resistance diminishes (such as power-assisted can be subject to during following current), causes the load of main frame to diminish, under identical instantaneous fuel delivery, engine speed Accelerate, acting becomes many, speed of the ship in metres per second accelerates (raised speed equivalent to active)；When the resistance of outer bound pair ship becomes big (such as adverse current) When, correspondingly, the resistance that the propeller of ship is subject to becomes big, and the load of main frame becomes big, and under identical instantaneous fuel delivery, main frame turns Speed is slack-off, and acting tails off, and speed of the ship in metres per second is slack-off therewith (slowing down equivalent to active).

According to above-mentioned theoretical foundation, the marine main engine of present embodiment is navigated by water and fixed relative to traditional engine speed of determining Main engine power is navigated by water, and it can improve the response speed after ship changes to resistance, Δ w numerical value quickly be diminished so that ship Navigation reaches more preferable oil-saving effect.Same ship on the premise of load-carrying is the same, by real navigation under (from PORT OF CHANGSHU to the Qin Emperor's island harbour, it is allowed to which hours underway is 55 hours) the multiple test probability of accident (reduce), by the control of present embodiment When method processed is navigated by water, few 2~3 tons of the oil consumption that the oil consumption per one way is navigated by water than constant speed, with the market 4300 yuan of people of heavy oil per ton People's coin is converted, and a ship one way can save 8600~12900 yuans, greatly reduce energy resource consumption, save boat Row cost.

Further, in the present embodiment, the default instantaneous fuel delivery can be set by navigating by water the experience of accumulation, The default instantaneous fuel delivery can be calculated by computing module 300.

The computing module 300 can be used for：According to navigation distance and permission hours underway most long, navigation permission is calculated most slow Speed；And the load on host computers navigated by water in hydrostatic according to navigation permission most jogging speed and ship, calculate required instantaneous fuel feeding Amount, as default instantaneous fuel delivery.Usually, in ship's navigation, can from the hours underway for being spent of origin-to-destination The interval of fluctuation that to be can allow, such as hours underway from PORT OF CHANGSHU to PORT OF QINHUANGDAO can in 50 hours to 55 hours, Now permission hours underway most long is 55 hours.So, you can calculated with permission hours underway most long according to navigation distance Navigate by water the most jogging speed for allowing.It is as mentioned above, during Hainan Airlines, it is impossible to always adverse current or following current, therefore with ship The load on host computers navigated by water in hydrostatic is obtained and presets instantaneous fuel delivery as with reference to being calculated.The manner is because using most It is long to allow hours underway, the default instantaneous fuel delivery of minimum can be found.

The computing module 300 can also coordinate the control module 200, and the control module 200 is for gradually changing institute State the instantaneous fuel delivery of marine main engine, the computing module 300 navigates by water predetermined road under being used to calculating respectively each instantaneous fuel delivery Oil consumption corresponding to journey；And the minimum instantaneous fuel delivery of the predetermined distance oil consumption of navigation is calculated, as default instantaneous fuel delivery. In this programme, the instantaneous fuel delivery of the marine main engine can be gradually changed after ship starts navigation, can also entered in ship After entering conventional navigation, then the instantaneous fuel delivery of the marine main engine is gradually changed, and can become according under each instantaneous fuel delivery In the stable speed of a ship or plane (because, it is necessary to by a time delay, the navigation to ship could be reflected after ship changes instantaneous fuel delivery In speed, and in water, headway is more difficult accurately to be rested in a value, can only tend towards stability), calculate navigation predetermined Oil consumption corresponding to distance (such as 100 nautical miles).So, after multiple instantaneous fuel deliveries were attempted, you can find out the predetermined road of navigation The minimum instantaneous fuel delivery of journey oil consumption.Certainly, in the manner, can be often described by a cycle (usually 15 minutes) change The instantaneous fuel delivery of marine main engine once, with allow change after instantaneous fuel delivery can be reflected on the headway of ship.This The scheme of sample, more intelligent can search out suitable ship and preferably presets instantaneous fuel delivery.

Cause marine main engine to run beyond the security interval to avoid the instantaneous fuel delivery of above-mentioned change, or keep ship master Machine is operated in the interval of economic speed, and the configuration module 100 is used to configure the higher limit of the marine main engine rotating speed with Limit value.In this way, by controlling accelerator open degree the marine main engine can be controlled interior in the interval of the higher limit and the lower limit Operation, is that the instantaneous fuel delivery of change also has certain constant interval, and it can not turn to the change of instantaneous fuel delivery instantaneous at this The revolution of marine main engine is driven to exceed the higher limit or less than the lower limit under fuel delivery, to ensure the operation of marine main engine Safety and/or the economy of guarantee marine main engine operation.

When the control device of ship energy saving navigation corresponds to above-mentioned second embodiment, described device includes：

Cause marine main engine to run beyond the security interval to avoid the instantaneous fuel delivery of above-mentioned change, or keep ship master Machine is operated in the interval of economic speed, and described device also includes configuration module 100, and the configuration module 100 is used to configure institute State the higher limit and lower limit of marine main engine rotating speed.In this way, the marine main engine can be controlled described by controlling accelerator open degree Operation in the interval of higher limit and the lower limit, is that the instantaneous fuel delivery of change also has certain constant interval, and it can not Instantaneous fuel delivery is become and turns to the revolution that marine main engine is driven under the instantaneous fuel delivery more than the higher limit or less than described Lower limit, to ensure the operation safety of marine main engine and/or ensure the economy that marine main engine runs.

Further, in the present embodiment, before active feedback control vessel motion parameter, the configuration module 100 Instantaneous fuel delivery is preset for one can be pre-configured with, the control module 200 is used to, in routinely navigation, be opened by controlling throttle Degree, keeps the marine main engine to be run under the default instantaneous fuel delivery, until resistance suffered by the ship changes.

When the control device of ship energy saving navigation corresponds to above-mentioned three implementation method, it is relative to correspondence second For the device of implementation method, difference is that in the present embodiment, the computing module 300 is used to judge that the ship exists Whether suffered resistance changes during the navigation, and whether the variable quantity of suffered resistance is more than or equal to predetermined threshold value.Only when When the variable quantity of resistance suffered by ship is more than or equal to predetermined threshold value, the control module 200 just join by the corresponding operation for changing ship Number.Because during ship's navigation, if frequently there is resistance change, resulting in the need for frequently changing the fortune of ship Line parameter (such as instantaneous fuel delivery), is detrimental to energy-conservation.

Therefore, in the present embodiment, it is necessary to configuration module 100 is pre-configured with a predetermined threshold value, so, ship is only worked as When the variable quantity of suffered resistance is more than or equal to predetermined threshold value, just correspondingly change the instantaneous fuel delivery to marine main engine, in this way, can To the energy-conservation of ship advantageously.

When the control device of ship energy saving navigation corresponds to above-mentioned four implementation method, it is relative to correspondence second For the device of implementation method, difference is that the monitoring modular 400 is used to monitor the ground speed and speed through water of ship, With judge ship it is current by resistance situation, be to judge that ship is presently at following current or adverse current.

Meanwhile, the computing module 300 is additionally operable to the ground speed of Ship ' and the difference (water poor) of speed through water, To judge whether the instantaneous fuel delivery for needing the control module 200 to change marine main engine, the control module is used for：

When the control device of ship energy saving navigation corresponds to above-mentioned five implementation method, it is relative to correspondence the 3rd For the device of implementation method, difference is that the monitoring modular 400 can only monitor the ground speed of ship, with by ship Ground speed come judge ship it is current by resistance situation, be to judge that ship is presently at following current or adverse current.

The computing module 300 is used for the variable quantity by the ground speed of Ship ', to judge whether that needs are described Control module 200 changes the instantaneous fuel delivery of marine main engine, and the control module 200 is used for：

When the control device of ship energy saving navigation corresponds to above-mentioned six implementation method, relative to above-mentioned embodiment party Formula, the emphasis of the control device of the ship energy saving navigation is used for, and the instantaneous fuel feeding for more optimizing is determined by way of optimizing Amount, and navigated by water by the preferred instantaneous fuel delivery for calculating, to optimize the oil consumption of ship's navigation, described device includes：
