Technical Field

[0001] The utility model belongs to the field of ship control, and specifically relates to an intelligent green ship automatic acceleration control system. Background Art

[0002] Ship acceleration is usually achieved by adjusting the output power of the ship's main engine (main engine). The following are the general ways to achieve ship acceleration:

[0003] 1. Adjust the main engine speed: The main engine of a ship is usually a diesel engine or a turbine, etc. The forward speed of the ship can be controlled by adjusting the main engine speed. Increasing the main engine speed can increase the speed of the ship and achieve acceleration.

[0004] 2. Control the propeller: The propeller of a ship is usually a propeller or a water jet propeller. The propulsion force of the ship is controlled by adjusting the blade angle of the propeller or the amount of water sprayed by the propeller, thereby achieving acceleration.

[0005] 3. Adjust the fuel supply: When the ship accelerates, the fuel supply needs to be increased to increase the output power of the main engine. By adjusting the fuel injection system or the fuel pump, the fuel supply is controlled to adjust the output power of the main engine.

[0006] 4. Utilize electric propulsion system: Some modern ships use electric propulsion system to control the speed and acceleration of the ship by adjusting the power output of electric propellers. Electric propulsion system has the advantages of fast response speed and high regulation accuracy.

[0007] 5. Auxiliary propulsion device: Some ships are also equipped with auxiliary propulsion devices, such as water jets, rudder spinners, side thrusters, etc. By controlling the work of these auxiliary propulsion devices, the acceleration and manipulation of the ship can be achieved.

[0008] There are some shortcomings in the current ship acceleration methods, mainly including the following aspects:

[0009] 1. Low energy efficiency: Traditional ship acceleration methods usually rely on fuel supply and adjustment of main engine output power. This method has certain limitations in energy utilization efficiency and relatively low energy efficiency.

[0010] 2. Slow response speed: Traditional ship acceleration methods require manual operation by the crew or rely on mechanical adjustment, which has a slow response speed and cannot meet application scenarios with high requirements for speed changes.

[0011] 3. Low control accuracy: Traditional ship acceleration methods are limited by the ship structure and power system performance, and the control accuracy is limited, making it difficult to achieve precise control of speed.

[0012] 4. Environmental pollution: Traditional ship acceleration methods mainly rely on fuel supply. The exhaust gas and wastewater generated by burning fuel will pollute the environment and are not conducive to the protection of the marine environment.

[0013] 5. High maintenance cost: Traditional ship acceleration methods involve components such as fuel supply systems, main engines and propellers, which require regular maintenance and servicing, and have high maintenance costs.

In order to make the technical solution of the utility model clearer, the utility model is explained through the following embodiments:

[0029] An intelligent green ship automatic acceleration control system, such as Figure 1As shown, the system includes a sensor module, a controller, a human-computer interaction module, a communication module, a remote control module, and a ship power module, wherein: the controller is connected to the sensor module, the human-computer interaction module, the communication module, and the ship power module respectively; the communication module is connected to the remote control module. In this embodiment, the controller selects the central processing control unit CPU, and with its efficient data processing capability and intelligent control capability, the ship control accuracy is improved, thereby realizing accurate control of the ship speed.

[0030] The realization of automatic acceleration of the ship requires that there are no obstacles or other ships on the ship's course to avoid collision when the ship is automatically accelerated. Therefore, the present embodiment is provided with a sensor module, specifically involving a variety of sensors, and the safety of the ship during automatic acceleration is ensured through the detection of a variety of sensors. Specifically, the sensor module of the present embodiment includes a speed sensor, a global satellite navigation system, a radar, a camera, an automatic identification system for ships AIS, and a depth sounder, wherein the speed sensor, the global satellite navigation system, the radar, the camera, the automatic identification system for ships AIS, and the depth sounder are respectively connected to the controller.

[0031] In this embodiment, the speed sensor is used to detect the speed of the ship in real time and upload it to the controller; the global satellite navigation system is used to locate the ship and provide the ship's position information to the controller in real time. The global satellite navigation system of this embodiment selects the Beidou satellite navigation system, which can improve the accuracy of ship positioning; radar and camera are used to detect obstacle information around the ship in the channel, such as other ships, reefs, buoys, etc., and upload the obstacle information to the controller to assist in determining whether the channel to which the ship belongs is open, wherein the radar includes a millimeter wave radar, which can improve the detection accuracy. The sensor module of this embodiment is also provided with an automatic identification system AIS, which is connected to the controller to obtain information about other ships near the ship and upload it to the controller. The automatic identification system AIS obtains information about other ships near the ship through information exchange with other ships, realizes early perception, and avoids ship collision. The sensor module of this embodiment is also provided with a depth sounder, which is connected to the controller to obtain water depth information and upload it to the controller to ensure that the ship always remains at a safe water level to prevent it from running aground.

When the controller finds an abnormal situation from the information detected by the sensor, it promptly informs the crew through the audible and visual alarm, such as detecting that the distance to the obstacle is too close, so as to facilitate timely response in an emergency.

[0033] The ship power module of this embodiment includes an electric propulsion system and an automatic rudder, which are respectively connected to a controller and used to control the acceleration and heading of the ship according to the control signal of the controller. Different from the traditional ship which achieves ship acceleration by adjusting the output power of the main engine, controlling the working state of the propeller and adjusting the fuel supply, this embodiment adopts an electric propulsion system, which controls the speed and acceleration of the ship by adjusting the power output of the electric propulsion system. It responds faster to the control signal and has higher control accuracy. At the same time, the electric control method can reduce environmental pollution and maintenance costs compared with fuel control. This embodiment adopts an automatic rudder, which can automatically control the ship's heading according to the control signal of the controller.

[0034] The remote control module of this embodiment is a shore-based control platform, which communicates with the controller through the communication module, and is used to analyze the sensor detection information received and processed by the controller, and then convey the permission of automatic acceleration and safe acceleration parameter information to the ship according to the analysis results.

[0035] In this embodiment, after receiving the detection information uploaded by the sensor, the controller will first perform simple processing, such as conversion of analog signals and digital signals, abnormal judgment of detection information, etc., and then the controller will send the processed detection information to the human-computer interaction module and the communication module respectively. The human-computer interaction module of this embodiment includes a touch screen, which is connected to the controller. The human-computer interaction module displays the detection information to the crew in the form of pictures and texts, and the crew can set the control target and adjust the control parameters through human-computer interaction and output them to the controller, thereby realizing the operation status monitoring, manual intervention and intelligent control of the ship. In addition, the communication module of this embodiment will send the processed detection information to the shore-based control platform, and analyze the detection information with the help of the powerful data processing capability of the shore-based control platform to determine whether the ship can accelerate at this time and provide the ship's safe acceleration parameter information when it can accelerate. When it can accelerate, the shore-based control platform will convey the permission of automatic acceleration and the safe acceleration parameter information to the controller through the communication module, and the controller will then send a control signal to the corresponding device of the ship's power module according to the above information. After receiving the control signal, the corresponding device of the ship's power module performs an acceleration operation, including an increase in the output power of the motor, and finally realizes the automatic acceleration of the ship.

[0036] The utility model mainly calculates the current ship status, channel status and other information detected by the sensor through the shore-based control platform to obtain the ship's safe acceleration parameters, and then the CPU issues an acceleration command to the ship's power module, thereby realizing automatic acceleration of the ship. At the same time, a human-machine interaction module is also provided for monitoring and human intervention, and a safety warning module is provided for safety warning. Under the premise of ensuring safety, the utility model realizes automatic acceleration, optimizes energy efficiency, improves freight efficiency, and reduces energy waste and transportation time costs.
