Description

Technical Field

[0001] This patent relates to the technical field of control systems, and particularly to an intelligent control system for large-horsepower electric boats. Background Art

[0002] Under the background of "dual carbon", transportation emissions reduction is the most prominent. New energy technologies with power batteries and motors as the core have achieved relatively prominent achievements in the field of road transportation. Currently, the electrification of water transportation mainly for inland and offshore ships is in the stage of technology reserve in the early stage of industrial development, and the industrialization market has broad prospects.

[0003] An outboard motor usually uses a digital handle to collect the gear position and propulsion opening, a steering wheel for steering control, and transmits the signal to the whole-ship controller through the CAN network for propulsion control. The failure of the digital handle or the steering wheel will affect the failure of the boat's power control, thus affecting the driving safety of the boat.

[0004] Based on the above deficiencies, it is necessary to make improvements. Summary of the Invention

[0005] In order to ensure the safety of personnel and property and put forward higher requirements for the safety of sea travel, the utility model provides an intelligent control system for large-horsepower electric boats, including a battery subsystem, an outboard engine subsystem, a whole-ship controller, a control subsystem, and a communication subsystem; the communication subsystem is a CAN network, and the battery subsystem, the outboard engine subsystem, and the control subsystem are all connected to the whole-ship controller through the CAN network; the control subsystem includes a mechanical controller and a touch display screen. The mechanical controller transmits the control signal to the whole-ship controller, and the whole-ship controller transmits the control signal to the battery subsystem and the outboard engine subsystem. At the same time, the whole-ship controller synchronously backs up the control signal to the touch display screen, and the touch display screen is independent of the mechanical controller.

[0006] As another alternative preferred solution: The touch display screen includes virtual control switches. When the virtual control switches are turned on, the whole-ship controller receives the control signal from the touch display screen; when the virtual control switches are turned off, the touch display screen is only used to display the navigation attitude of the boat and the working state of the outboard engine.

[0007] As another alternative preferred solution: The mechanical controller includes a steering wheel and a mechanical handle; or, the mechanical controller includes a steering wheel and a push rod.

[0008] As another alternative preferred solution: The touch display screen includes gear control, speed control, and steering control.

[0009] As another alternative preferred solution: The steering control includes left steering control, right steering control, and centering control.

[0010] As another alternative preferred solution: The gear control includes forward gears, neutral gear, and reverse gears.

[0011] As another alternative preferred solution: The speed control includes acceleration control, deceleration control, and speed holding.

[0012] The advantages of this patent compared with the prior art are as follows: A virtual control interface is added to the touch display screen to back up the functions of the digital handle and the steering wheel. After a serious failure occurs in the digital handle or the steering wheel, the boat can continue to sail safely, solving the serious system problem that the boat loses power due to the failure of the mechanical controller, effectively improving the safety of the boat system, and providing more safety guarantees for sea travel.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0018] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] The following are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly.

[0020] Embodiment, see Figure 1 As shown: An intelligent control system for a large-horsepower electric boat includes a battery subsystem 2, an outboard engine subsystem 3, a whole-ship controller 1, a control subsystem, and a communication subsystem; the communication subsystem is a CAN network 6, and the battery subsystem 2, the outboard engine subsystem 3, and the control subsystem are all connected to the whole-ship controller 1 through the CAN network 6; the control subsystem includes a mechanical controller 4 and a touch display screen 5. The mechanical controller 4 transmits control signals to the whole-ship controller 1, and the whole-ship controller 1 transmits control signals to the battery subsystem 2 and the outboard engine subsystem 3. At the same time, the whole-ship controller 1 synchronously backs up the control signals to the touch display screen 5, and the touch display screen 5 is independent of the mechanical controller 4.

[0021] The touch display screen 5 includes virtual control switches. When the virtual control switches are turned on, the whole-ship controller 1 receives the control signals of the touch display screen 5; when the virtual control switches are turned off, the touch display screen 5 is only used to display the navigation attitude of the boat and the working state of the outboard engine.

[0022] The mechanical controller 4 includes a steering wheel and a mechanical handle; alternatively, the mechanical controller includes a steering wheel and a push rod.

[0023] The touch display screen 5 includes gear control, speed control, and steering control. The steering control includes left steering control, right steering control, and centering control. The gear control includes forward gear, neutral gear, and reverse gear. The speed control includes acceleration control, deceleration control, and speed holding.

[0024] In this embodiment, a virtual handle control interface is added to the touch display screen 5, and this interface is in a hidden state when the digital handle functions normally.

[0025] Under normal circumstances, the whole-ship controller uses the gear signal and the propulsion opening signal transmitted by the digital handle for propulsion control.

[0026] When a serious fault occurs in the digital handle, resulting in the failure to transmit the gear signal and the propulsion opening signal to the whole-ship controller 1, after detecting the fault, the whole-ship controller 1 sends a virtual handle control request signal to the touch display screen 5 through the CAN network 6. After receiving the request, the interface of the touch display screen 5 switches to the virtual handle control interface, and the driver changes to use this interface for boat propulsion control.

[0027] If the digital handle fault is restored, in order to maintain the stability and coherence of boat control, the driver continues to use the virtual handle control interface of the touch display screen 5 for boat propulsion control. At the same time, a touch switch for switching to the real handle control is displayed at the upper left corner of the interface. The driver can click this switch to switch back to the real handle for boat propulsion control.

[0028] When a serious fault occurs in the digital steering wheel, resulting in the failure to transmit the steering wheel steering angle signal to the whole-ship controller 1, after detecting the fault, the whole-ship controller 1 sends a virtual steering wheel control request signal to the touch display screen 5 through the CAN network 6. After receiving the request, the interface of the touch display screen 5 switches to the virtual steering wheel control interface, and the driver changes to use this interface for boat steering control.

[0029] If the digital steering wheel fault is restored, in order to maintain the stability and coherence of boat control, the driver continues to use the virtual steering wheel control interface of the touch display screen 5 for boat steering control. At the same time, a touch switch for switching to the real steering wheel control is displayed at the upper left corner of the interface. The driver can click this switch to switch back to the real steering wheel for boat steering control.

[0030] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
