The embodiment of the present application discloses a receiving mode selection method and device based on signal diversity receiving. In the technical solution provided by the embodiment of the present application, in the initial signal receiving mode, several signals are independently received through the main antenna, and the first signal quality parameter of the received signal is determined. When the first signal quality parameter is lower than the first signal quality parameter When the threshold is reached, the current signal receiving mode is switched to the diversity receiving mode, and the master antenna and several slave antennas perform diversity reception of signals, and combine the signals received by diversity to obtain a combined signal, and within the set first time period, continuously The set number of times detects that the first signal quality parameter of the signal received by the main antenna reaches the first signal quality parameter threshold, and restores the current signal receiving mode to the initial signal receiving mode. Using the above-mentioned technical means can guarantee the signal receiving performance of the system, optimize the energy consumption management of the system, and improve the signal processing efficiency.

The invention discloses a double-plate clutch hybrid power assembly suitable for a new energy automobile. An engine, an elastic damping connecting unit, a first motor, a double-plate clutch and a second motor of the double-plate clutch hybrid power assembly are coaxially connected in sequence. An output shaft of the second motor is connected with a drive axle assembly. An energy-storing power source is electrically connected with a first motor controller, a second motor controller and a vehicle control unit. The first motor controller is electrically connected with the vehicle control unit and the first motor. The second motor controller is electrically connected with the vehicle control unit and the second motor. The double-plate clutch does not generate axial force to the motors and the engine, and the functions of the clutch, a two-gear transmission, impact overload protection, forward and reverse separation, non-power-interruption speed-differential gear shifting and the like are achieved. Switching response is rapid, reliability is high, energy consumption is low, and efficiency is high. Energy output can be randomly switched between the engine and the energy-storing power source according to working conditions, energy can be recycled, and energy management fit is more reasonable.

The invention provides a method for power generation and voyage optimization of a mobile energy network influenced by wind resources, including: selecting four characteristics of wind speed, temperature, air pressure and cloud cover as the data input for prediction; Training set and test set; normalize the sample data. Based on the data-driven mobile energy network power generation and voyage joint optimization method, the present invention takes the influence of the offshore wind speed on the speed of the all-electric ship into account, and can more effectively adjust the actual ship speed and achieve better ship energy management; The operation cost objective function is optimized, and the operation cost of energy storage is taken into account, which is more in line with the actual operation scenario; through the piecewise linearization method, the optimization model is converted into a mixed integer linear programming model, which solves the problem that mixed integer nonlinear programming is difficult to solve. problem; not limited to all-electric ship power systems, but can also be used in mobile energy networks such as land electric vehicles.
