Figure 1 shows that boats and ships energy efficiency control system 100 according to an embodiment of the invention.Boats and ships energy efficiency control system 100 comprises network of ship 106, sensor group 102, boats and ships efficiency controller 104, host module 108.Network of ship 106 provides electric energy for boats and ships.Sensor group 102 detects the environmental variance residing for boats and ships, and produces the testing signal 152 representing these environmental variances.In one embodiment, sensor group 102 comprises water velocity meter, anemoclinograph, fuel consumption meter and rotating speed torsionmeter, is respectively used to measure water velocity, wind direction and wind speed, the oil consumption of boats and ships and the rotating speed of engine of boat and ship (such as: the duel fuel engine 138 in host module 108) and moment of torsion.In one embodiment, each sensor uses wireless network and boats and ships efficiency controller 104 to exchange information.Host module 108 comprises duel fuel engine 138.Duel fuel engine 138 burns the first fuel and the second fuel, and provides power to the propeller cavitation 116 of boats and ships.What deserves to be explained is, the size of the power needed for boats and ships is relevant with environmental factor.The rotating speed of duel fuel engine 138 is determined by described first fuel and described second fuel feed and ratio between the two.In one embodiment, the first fuel and the second fuel are LNG Liquefied natural gas (LNG) and diesel oil respectively.Those skilled in the art will appreciate that the first fuel of the present invention and the second fuel can be also other fuel, do not repeat them here.Host module 108 also comprises main engine remote control device 132, oil-feeding device for engine 134 and motor air feeder 136.Main engine remote control device 132 produces control signal 152 and 154.Oil-feeding device for engine 134 and motor air feeder 136 control the consumption of motor diesel oil and LNG Liquefied natural gas (LNG) according to control signal 152 and 154, thus the ratio between condition lng (LNG) and diesel oil, thus, the rotating speed by controlling duel fuel engine 138 can regulate the power and energy consumption that are supplied to propeller cavitation 116.
Boats and ships efficiency controller 104 is connected with main engine remote control device 132 with sensor group 102.Boats and ships efficiency controller 104 receives testing signal 152, and calculate fuel feed corresponding to duel fuel engine 138 power required under current environment variable and least energy consumption value accordingly, and produce the first control signal 156 representing fuel feed and least energy consumption value.In one embodiment, the power consumption values of duel fuel engine 138 can be represented by equivalent fuel consumption value.Such as: the use amount use amount of LNG Liquefied natural gas being converted to the diesel oil producing equal energy.Thus, equivalent fuel consumption value equals the summation of the diesel oil use amount after being changed by rock gas consumption and actual diesel oil use amount.Main engine remote control device 132 regulates delivery volume and the ratio between the two of the first fuel and described second fuel according to the first control signal 156, thus make duel fuel engine produce needed for power and its rotating speed equals corresponding to least energy consumption value tachometer value.Illustrate, the energy consumption of boats and ships unit distance (below also referred to as: unit oil consumption) can be expressed as:
Wherein, Q

ts]
arepresent the resistance coefficient that boats and ships are total, g
erepresent the amount of fuel that unit per hour useful horsepower consumes, n represents engine speed.More particularly, complex environment factor (comprising water velocity, wind direction and wind-force size etc.) can produce the resistance of different direction and size to the operation of boats and ships, namely affect the resistance coefficient [C that boats and ships are total
ts]
a.Therefore, if resistance coefficient [C
ts]
aincrease, then need to increase unit main frame unit distance oil consumption, also namely increase the equivalent delivery volume of the first fuel and the second fuel, vice versa.Meanwhile, from formula (1), (resistance coefficient [C that namely boats and ships are total under a certain specific navigation environment
ts]
aduring for a certain particular value), the oil consumption of main frame unit distance is the quadratic function of rotating speed.Because the specific energy consumption of two kinds of fuel is different, so under the prerequisite ensureing the energy resource supply under specific environment, energy consumption can be made to be minimum value under this specific navigation environment.What deserves to be explained is, clear for illustrating, formula (1) is the simplified model provided according to particular boat mode of operation, those skilled in the art it will be appreciated that, due to the difference of Ship Structure and the method for operation, the specific energy consumption of boats and ships also can be represented by other formula, and is not limited to formula (1).
