Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0017] Figure 1 This is a schematic diagram of the lateral thruster control system in a preferred embodiment of the present invention; The attached figures are labeled as follows: Remote control module-1, terminal control module-2, cloud platform server-21, database-22, local control module-3, execution and drive module-4. Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0019] like Figure 1 As shown, the lateral thruster of the intelligent ship in this embodiment includes a control system, which comprises a remote control module 1, a terminal control module 2, a local control module 3, an execution and drive module 4, and an Internet of Things (IoT) module (not shown). Specifically, the remote control module 1 is configured to remotely control the lateral thruster via a wireless network; the terminal control module 2 is configured to perform data parsing, forwarding, log recording, and backup; the local control module 3 is configured to perform real-time acquisition of sensor data, logic control, environmental monitoring, and fault alarm; and the execution and drive module 4 is configured to receive instructions from the local control module 3 to achieve thrust output.

[0020] Furthermore, the terminal control module 2 is connected to both the remote control module 1 and the local control module 3, and the local control module 3 is also connected to the execution and drive module 4. The control system in this embodiment also includes an uplink and a downlink formed by the various modules. The uplink is formed sequentially by the execution and drive module 4, the local control module 3, the terminal control module 2, and the remote control module 1, and is configured for status feedback, alarms, data monitoring, and trend analysis. The downlink is formed sequentially by the remote control module 1, the terminal control module 2, the local control module 3, and the execution and drive module 4, and is configured for thrust command issuance, parameter setting, and emergency command control. In addition, the control system in this embodiment also includes edge closed-loop control, meaning that when the cloud and / or remote connection is lost, the local PLC can still independently perform protection control.

[0021] Furthermore, the terminal control module 2 acts as the central scheduling node of the entire system, primarily undertaking parsing, forwarding, caching, and big data analysis functions. The terminal control module 2 includes a cloud platform server 21 and a database 22. The cloud platform server 21 and database 22 communicate bidirectionally, as do the local control module 3 and the remote control module 1. The cloud platform server is configured to write data to and / or read data from the database 22, and the database 22 is configured to store data. In this embodiment, the remote control module 1 is a mobile terminal, such as a tablet, mobile phone, or dedicated handheld terminal.

[0022] The local control module 3 and the execution and drive module 4 communicate bidirectionally. The local control module 3 serves as the edge intelligent layer of the entire system. When the cloud connection drops or the network becomes noisy, the local PLC will automatically take over to perform automatic protection (e.g., overcurrent, overvoltage, overtemperature, water leakage, abnormal vibration, etc.). The local control module 3 includes sensor components configured to collect real-time data on current, voltage, pressure, temperature, humidity, and rotational speed. The data collected by the sensor components is uploaded to the cloud platform server 21 via the Internet of Things (IoT) module.

[0023] Specifically, the sensor assembly includes a current sensor for real-time current data acquisition, a voltage sensor for real-time voltage data acquisition, a pressure sensor for real-time pressure data acquisition, a temperature sensor for real-time temperature data acquisition, a humidity sensor for real-time humidity data acquisition, and a speed sensor for real-time propeller speed data acquisition. The sensor assembly also includes vibration damping sensors and cabinet door status sensors. The vibration damping sensors monitor for abnormal vibrations or structural impacts to the central control box during ship operation, providing a basis for equipment operational safety and fault warnings. The cabinet door status sensors monitor the open or closed status of the central control box door.

[0024] The execution and drive module 4 includes a frequency converter, a motor, and a thruster body. The frequency converter is connected to the motor, and the motor is connected to the thruster body to drive the thruster body to generate thrust.

[0025] In this embodiment, the control flow of the lateral thruster control system is as follows: The following explanation uses the example of a user setting "thrust 60%" in remote control module 1: Step 1: The remote control module 1 sends an encrypted command packet (thrust at 60%) to the cloud platform server 21, and the cloud platform server 21 performs legality verification and authorization authentication.

[0026] Step 2: The cloud platform server 21 forwards the thrust command to the PLC of the local control module 3. After receiving the command, the PLC performs logical judgment (whether the power supply is normal / no alarm / no emergency stop trigger, etc.).

[0027] Step 3: The local control module 3 sends the analog signal to the frequency converter of the execution and drive module 4 via Ethernet. The frequency converter further adjusts the output frequency to control the motor speed, and the thruster outputs the corresponding lateral thrust.

[0028] Step 4: The execution and drive module 4 transmits the actual current, speed, thrust direction, vibration and temperature data back to the PLC of the local control module 3. The PLC then uploads the data to the cloud platform server 21. The cloud platform server 21 pushes the real-time data to the remote control module 1, which displays the data in real time, thereby realizing full-link closed-loop control.

[0029] The control system of this utility model has full-link data acquisition and multi-node communication capabilities, and can be used in ship side thruster application scenarios to realize remote control, intelligent monitoring, safety protection and data-driven operation and maintenance of the side thruster.

[0030] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
