Description

Technical Field

[0002] During the operation of traditional ship unloaders, manual adjustments of the trolley's travel speed and vertical height are often required based on experience to control the material flow rate. This method is not only inefficient, but also difficult to ensure the stability and accuracy of the material flow rate. In addition, manual operation also poses safety risks. Once a failure or abnormal situation occurs, it is difficult to respond and handle it in a timely manner. Summary of the invention

The system can monitor key parameters such as motor current in real time, automatically adjust the travel speed and vertical height of the trolley through an intelligent control algorithm, achieve precise control of the material flow rate, and support remote monitoring and operation to improve operating efficiency and safety.

[0004] Host computer software: As the core control center of the system, the host computer software integrates a user-friendly operation interface, allowing users to set flow target values, view the real-time status of the system (including key parameters such as motor current, vehicle position, height, etc.), and receive and process system alarm information. In addition, the software also has data analysis and report generation functions, providing strong support for subsequent optimization and management.

[0005] High-precision sensors: Distributed in key parts of the ship unloader, they are used to monitor multi-dimensional operating parameters such as motor current, temperature, pressure, vibration, etc. in real time. These sensors are designed with high precision and high reliability to ensure the accuracy and real-time nature of data collection.

[0006] Furthermore, the host computer software receives data from various high-precision sensors in real time through preset interfaces and protocols, including key parameters such as motor current, temperature, pressure, vibration, etc., and performs preliminary processing on these data, such as filtering and denoising, to improve the accuracy and reliability of the data.

[0007] Intelligent controller: It has built-in advanced PID control algorithm and other intelligent control strategies, which can receive data from sensors, calculate the optimal control parameters through complex algorithms, and send control instructions to the actuator in real time. The application of PID control algorithm enables the system to respond quickly to flow changes and achieve precise flow control.

[0008] Furthermore, the data processed by the host computer software is sent to the intelligent controller. The built-in PID control algorithm of the controller calculates the optimal control parameters based on these data. The host computer software can send control instructions to the controller according to the flow target value set by the user, requiring the adjustment of the vehicle's travel speed and vertical height.

[0009] Actuator: It includes the motor and actuator that drives the trolley to move and adjust the vertical height. These actuators accurately adjust the position and height of the trolley according to the instructions of the controller, thereby achieving effective control of the material flow rate.

[0010] Furthermore, the controller converts the calculated optimal control parameters into specific control instructions, and drives the actuator to act through the electrical or hydraulic transmission system. The actuator adjusts the position and height of the trolley according to the instructions, thereby achieving precise control of the material flow rate.

[0011] Safety protection devices: including emergency stop button, overload protector, temperature sensor, etc., used to immediately cut off the power supply when the system fails or an abnormal situation occurs to prevent the situation from escalating, and issue an alarm to notify relevant personnel.

[0012] Furthermore, the safety protection device monitors the operating status of the system in real time. Once an abnormal situation is detected, the protection device will immediately cut off the power supply and send an alarm message to the host computer software. After receiving the alarm, the host computer software will immediately display relevant information and trigger other emergency measures.

[0013] Data storage and remote monitoring module: Built-in large-capacity data storage module is used to record key information such as historical data and fault records during system operation. At the same time, it supports remote monitoring and operation functions. Users can remotely access the upper computer software interface through the Internet or a dedicated network to achieve remote flow setting, system monitoring and remote control operations.

[0014] Furthermore, the data storage module records various data during the operation of the system in real time. The remote monitoring module allows the user to remotely access the upper computer software interface through the Internet or a dedicated network to view the real-time status and historical data of the system. The user can remotely control and operate the system through the remote monitoring module, and can also download historical data for further analysis and processing.

[0020] like Figure 1-Figure 2 As shown, the present invention provides an automatic flow control system for an unmanned ship unloader, the system comprising: The host computer software is used to receive user instructions, process data, and provide a user interface. As the core control center of the system, the host computer software integrates a user-friendly operation interface, allowing users to set flow target values, view the real-time status of the system, including key parameters such as motor current, vehicle position, height, etc., and receive and process system alarm information. In addition, the software also has data analysis and report generation functions, providing strong support for subsequent optimization and management.

[0021] Sensors are used to monitor the motor current in real time and transmit the current data to the controller. They are distributed in key parts of the ship unloader and are used to monitor the motor current, temperature, pressure, vibration and other multi-dimensional operating parameters in real time. These sensors are designed with high precision and high reliability to ensure the accuracy and real-time performance of data collection. The controller receives the current data from the sensor and automatically adjusts the travel speed and vertical height of the trolley according to the data to achieve automatic flow control; it has built-in advanced PID control algorithms and other intelligent control strategies, which can receive data from the sensor, calculate the optimal control parameters through complex algorithms, and send control instructions to the actuator in real time. The application of PID control algorithm enables the system to respond quickly to flow changes and achieve precise flow control. The actuator adjusts the trolley's travel speed and vertical height according to the controller's instructions; it includes the motor and its actuator that drives the trolley to travel and adjust the vertical height. These actuators accurately adjust the trolley's position and height according to the controller's instructions, thereby achieving effective control of the material flow rate.

[0022] The controller adopts PID control algorithm to adjust the flow rate, and adjusts the control parameters according to the error by constantly comparing the set flow target value and the actual flow value to achieve accurate control of the flow rate.

[0023] The host computer software provides a user interface that allows the user to set flow target values, view system status, receive system alarms, and perform other related operations.

[0024] The system also includes safety protection devices, including emergency stop buttons, overload protectors, temperature sensors, etc., which are used to immediately cut off power supply when a system failure or abnormal situation occurs to prevent the situation from escalating, and issue an alarm to notify relevant personnel.

[0025] The sensor is also used to monitor other operating parameters of the ship unloader, such as temperature, pressure, vibration, etc., and transmit these data to the controller so that the controller can comprehensively monitor and protect the system.

[0026] The system also includes a data storage module for storing historical operating data, fault records and other relevant information for subsequent data analysis, troubleshooting and system optimization.

[0027] The system supports remote monitoring and operation functions, allowing users to access the host computer software interface through a remote terminal to perform operations such as flow setting, system monitoring and remote control.

[0028] The system has good scalability and maintainability, and can be expanded in function and upgraded in hardware according to actual needs. It also provides user-friendly manuals and technical support services.

[0029] An automatic flow control system for an unmanned ship unloader, further comprising an automatic flow control method for an unmanned ship unloader, specifically comprising the following steps: S1: Real-time monitoring of the motor current of each mechanism through sensors; S2: The controller receives sensor data and uses the PID control algorithm to calculate the optimal control parameters; S3: The controller issues a control instruction according to the optimal control parameters; S4: The actuator adjusts the travel speed and vertical height of the trolley according to the control instructions to adjust the material flow rate.

[0030] In summary, the present invention mainly realizes precise control of material flow rate through data collection and preprocessing, control algorithm application, instruction sending and execution, feedback and adjustment, and real-time safety protection.

[0031] The ship unloader is equipped with a variety of high-precision sensors, such as main load sensors, auxiliary load sensors, speed sensors, and instantaneous flow meters, etc. These sensors collect various data related to the material flow in real time, such as load, speed, instantaneous flow, etc. Then the collected raw data is first pre-processed, including filtering, denoising, calibration and other steps to improve the accuracy and reliability of the data. The pre-processed data will be used for subsequent control decisions.

[0032] The controller uses a PID (proportional-integral-differential) control algorithm. According to the preset unloading flow command signal and the real-time feedback flow of the instantaneous flow meter, the PID algorithm calculates the control quantity (such as the speed or torque of the drive motor) to achieve precise control of the material flow. The PID algorithm can dynamically adjust the control quantity according to the real-time feedback signal to eliminate system deviations and ensure that the actual flow is consistent with the command flow; in order to further improve the control accuracy and response speed, the controller may also use more advanced control algorithms, such as fuzzy control, neural network control, etc. These algorithms can better handle system nonlinearity, time-varying and uncertainty.

[0033] The controller generates control instructions based on the calculation results of the control algorithm and sends them to the actuators, such as the drive motor and its actuators, through the electrical or hydraulic transmission system; after receiving the control instructions, the actuators adjust the parameters such as the trolley's travel speed and vertical height, thereby achieving precise control of the material flow rate. The response speed and accuracy of the actuators directly affect the control effect; sensors such as instantaneous flow meters continuously feed back real-time flow data to the controller, and the controller makes dynamic adjustments based on the feedback signals to ensure the consistency between the actual flow rate and the command flow rate; during the control process, the controller may also make real-time adjustments and optimizations based on changes in the system state and the influence of the external environment to cope with various uncertainties and challenges.

[0034] The safety protection device monitors the system's operating status and key parameters, such as motor current, temperature, pressure, etc., in real time, and immediately triggers the protection mechanism once an abnormal situation is detected; in an emergency, the safety protection device will quickly cut off the power supply or initiate other emergency measures to prevent the situation from escalating and protect the safety of equipment and personnel.
