The first motor driving module 6, the first motor 7 and the upright post 8 form a second propulsion system, and under the condition that the draught of the device is d, the second propulsion system is carried at the position from 0.1d to 0.5d, so that the force arm and the propulsion condition are met.
Temperature sensor 11 and pH value sensor 12 are fixed at the lowest position of last flotation tank 16 downside, and be electric connection between temperature sensor 11 and pH value sensor 12 and afterbody LCD screen 10, and temperature sensor 11 and pH value sensor 12 have the detection effect to the waters.
The second motor 13, the second motor driving module 14 and the floater flange 15 form a first propulsion system, the movement of the floater 9 in normal working is not influenced, the resistance of wave flowing around is reduced, the floater flange 15 is made of nylon materials, the floater flange 15 is in a hollow design, the second motor 13 is made of plastic materials, the density of the first propulsion system is controlled to be close to 1.15g/cm3, and the influence on the movement of the floater 9 is reduced.
The first motors 7 are symmetrically arranged at the outer sides of the upright posts 8 by 4, the 4 first motors 7 are positioned on the same plane, and the central shafts of the first motors 7 are horizontally arranged. Two groups of second motors 13 and second motor driving modules 14 are symmetrically arranged on the float flange 15, and the central shafts of the second motors 13 are vertically arranged.
According to the wave energy power generation platform control system with multiple degrees of freedom, when waves come into the platform to work, the floater 9 moves with two degrees of freedom of heaving and pitching under the action of the wave energy, the coil cuts magnetic induction power generation, and the monitoring sensor 2 is carried to detect the generated current and voltage in real time. The distance sensor 5 counts and forecasts the voyage of the floater 9 in the heave process, and the nine-axis module 3 can perform integral counting and forecasting on the movement of the floater 9 in the pitching process of the floater 9; the voltage and the current of the floater 9 at each position in the heave motion and the pitch motion at each moment can be obtained through data analysis, namely, the power generation amount of the whole floater 9 at each moment in the heave motion and the pitch motion can be obtained.

When the device is in laboratory still water and is unable to simulate wave conditions, the forced motion control compensation system of the present invention can be used. When the forced motion control compensation system receives the command of starting to work, the control center 1 sends a command of starting to move to the first motor driving module 6 and the second motor driving module 14 by the first propulsion system and the second propulsion system, so that the motors start to work. Under the state that the simulated floater 9 is vertically swung, the second motor 13 of the first propulsion system works at the same frequency, the whole floater 9 starts to move upwards relative to the water surface, when the carried distance sensor 5 is far away from the water bottom, the single chip microcomputer sends a signal to finish the work of the driving system, and the power generation platform can do deceleration movement and finally move downwards under the action of gravity. When the distance from the platform to the water surface becomes small, the distance sensor 5 releases a signal to the driving system to continue to start. From there, a simple harmonic cycle of motion in the vertical direction is repeated. Under the condition of simulating the pitching state of the floater 9, the second propulsion system sends a motion starting instruction to the first motor driving module 6 through the control center 1, so that the first motor 7 starts to work, the upright post 8 is pushed to enable the floater 9 to pitch, and the upright post 8 is enabled to rotate towards any direction by controlling the switches and the rotating speeds of the four first motors 7. When the specific value meeting the conditions is reached, the attitude sensor sends out a signal, the driving is stopped, and finally, the control device driven in one period is formed. In order to avoid that the forced motion control system influences the experiment under the real sea condition of the model, the system is made to be detachable.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
