Abstract

An embedded propulsion system for small or medium-sized electrically propelled watercraft and a control method thereof are disclosed, in particular relating to a propulsion control device for small or medium-sized electrically propelled watercraft and a control method thereof. The invention provides a propulsion control device which is convenient to operate and a control method thereof. The propulsion control device is provided with two control panels, one is a bridge control panel arranged on the bridge of the watercraft and the other is an engine room control panel arranged inside the engine room of the watercraft; the control switches and the indicator lights of the two control panels are reasonably arranged so that operation can be more convenient and state indication can be clearer; a CAN bus is arranged on the communication module of a microprocessor so that signal transmission can be more stable.

Description

technical field [0001] The invention relates to a control device and a control method for a ship propulsion system, in particular to a propulsion control device and a control method for small and medium electric propulsion ships. Background technique [0002] The electric propulsion ship has been recognized and concerned by the shipping industry for its energy saving, environmental protection and excellent maneuverability. The power plant and control system of the electric propulsion ship are as follows: figure 1 shown. Wherein the power plant includes left and right propellers 1, 1A, left and right propulsion motors 2, 2A and left and right frequency converters 3, 3A symmetrically installed on the left and starboard sides of the hull. For small and medium-sized electric propulsion ships, the left and right propulsion motors 2 and 2A generally use low-cost variable frequency asynchronous motors. The control system includes a propulsion controller 4 and a control panel 5. T...
