[0057] like Figures 1 to 5 As shown, in one embodiment, the present invention provides a height adaptation adjustment method based on a shore-side lifting platform system. By continuously measuring the height data of the deck surface and the horizontal plane, and through an adaptive control strategy, the height of multiple shore-side lifting platforms is continuously adjusted to adapt to the ever-changing height data. This helps to solve the technical problem in the prior art of lacking an adjustment method to adapt to constantly changing height data.

[0058] The shore-side lifting platform system includes multiple shore-side lifting platforms, each with a flat plate spaced apart. The platforms overlap on top to form a deck surface.

[0060] This step provides a specific procedure for obtaining height data.

[0062] Because the height data constantly changes due to tides, the top deck surface will also adaptively adjust according to its specific conditions. This adjustment strategy is the control strategy, which issues control commands for the optimal solution. The actuator control unit mainly implements the control of the actuator to complete the prescribed actions based on the control commands issued by the adaptive control unit, including the controller and the operation box.

[0063] S103, adjust the attitude of the shore-side lifting platform according to the control strategy to adapt to the current height data.

[0064] This embodiment provides a specific implementation method for a height adaptation adjustment method based on a riverside lifting platform.

[0065] In one embodiment, the shore-side lifting platform includes a lifting frame and lifting cylinders on both sides;

[0066] The lifting frame includes a base frame and a top frame, with the top frame located above the base frame and capable of being raised and lowered by a lifting mechanism.

[0067] The top frame is driven by the lifting cylinder to raise it to different heights.

[0068] In one embodiment, the lifting mechanism is a rope pulling mechanism.

[0069] In one embodiment, before the step of collecting the height data of the deck surface above the horizontal plane, the method further includes:

[0070] Obtain the location of the dock and berth;

[0071] Based on the location of the wharf and the location of the berth platform, the position of each shore-side lifting platform is determined.

[0072] In one embodiment, the present invention also provides a height adaptation adjustment system based on a riverside lifting platform system and a height adaptation adjustment method based on a riverside lifting platform system. The height adaptation adjustment system based on a riverside lifting platform system includes:

[0073] An online monitoring unit is used to locate the current unloading channel position and collect the height data of the deck surface from the horizontal plane through a data platform, wherein the data platform includes a positioning module, a sea level data acquisition module, and a ranging module.

[0074] In one embodiment, the height adaptation adjustment system based on the shore-side lifting platform system further includes a data acquisition and processing unit;

[0075] The data acquisition and processing unit is used to collect and process real-time status data of the shore-side lifting platform. The data acquisition and processing unit includes an inclination angle acquisition module, a lifting height acquisition module, and a hydraulic status acquisition module.

[0076] In one embodiment, the height adaptation adjustment system based on the shore-side lifting platform system further includes a communication unit;

[0077] The communication unit is used to realize data interaction among multiple shore-side lifting platforms and determine the online status of a single shore-side lifting platform, i.e., each posture, which includes position, height, angle, etc.

[0078] In one embodiment, the height adaptation adjustment system based on the shore-side lifting platform system further includes a database unit;

[0079] The database unit is used to collect, classify, store, and retrieve data from the online monitoring unit and the data acquisition unit.

[0080] In one embodiment, the height adaptation adjustment system based on the shore-side lifting platform system further includes an adaptive control unit;

[0081] The adaptive control unit is used to control the actuator to complete the prescribed actions according to the control commands issued by the adaptive control unit.

[0082] In one embodiment, the height adaptation adjustment system based on the shore-side lifting platform system further includes an early warning unit;

[0083] The early warning unit is used to identify dangerous operations during the execution of the mechanism of the shore-side lifting platform and issue alarm information.

[0084] Based on the above methods and systems, the overall structure is further explained as follows:

[0085] A highly adaptive adjustment and control strategy includes a manual control strategy, a semi-automatic control strategy, and a fully automatic control strategy.

[0086] The manual control strategy involves the operator directly operating the actuator through the control box, relying entirely on the operator's experience to gradually adjust the height of each quayside lifting platform, ultimately achieving the height adjustment of the unloading channel. In case of a dangerous situation, the early warning unit will issue an alarm signal.

[0087] The semi-automatic control strategy involves the operator controlling the actuator through the control box to adjust the height of a single shore-side lifting platform. When the angle of the ramp of an adjacent shore-side lifting platform exceeds the control range, the adaptive control unit will adjust the height of the adjacent shore-side lifting platform until the control requirements are met.

[0088] The fully automated control strategy involves obtaining the current sea level height through an online monitoring unit, acquiring and processing the current status data of the shore-based lifting platforms through a data acquisition and processing unit, storing and classifying the data through a database unit, and transmitting it to an adaptive control unit. The adaptive control unit analyzes the data to determine the optimal control algorithm, which is then synchronously transmitted to the six shore-based lifting platforms via a communication unit. The actuator control unit responds to control commands to control the actuators. This fully automated control strategy enables unattended operation of the unloading channel and allows for simultaneous adjustment of the height of the six shore-based lifting platforms when the sea level changes, reducing the time required for height adjustment of the unloading channel.

[0089] Specifically, the online monitoring unit includes a positioning module, a sea level data acquisition module, and a ranging module. The positioning module specifically refers to a BeiDou positioning module, which can acquire the location information of the shore-based elevator platform. The sea level data acquisition module refers to a platform that publishes sea level data; combined with the location information acquired by the BeiDou positioning module, it can obtain real-time sea level data. The ranging module specifically refers to an ultrasonic ranging module, which can locally measure the height of the deck surface above the sea level. The locally acquired data and the sea level data acquired by the publishing platform are weighted and averaged to obtain the current actual sea level height.

[0090] Specifically, the data acquisition and processing unit includes a tilt angle acquisition module, a lifting height acquisition module, and a hydraulic status acquisition module. The tilt angle acquisition module includes vehicle body tilt angle sensors and ramp tilt angle sensors, which can monitor the tilt angle data of the vehicle body and ramp in real time. The lifting height acquisition module specifically refers to the cable sensor that measures the lifting cylinder, which can measure the lifting height of the pontoon platform. The hydraulic status acquisition module includes oil pressure sensors and hydraulic flow sensors, which can monitor the oil pressure and inflow / outflow of the lifting cylinder. Simultaneously, the data acquisition and processing unit performs standardization processing and data transmission based on the different types of data.

[0091] Specifically, the communication unit mainly uses CAN communication to realize data interaction among multiple shore-side lifting platforms and determine the online status of a single shore-side lifting platform.

[0092] Specifically, the database unit uses the MariaDB database, which can classify and store the collected data to meet the data retrieval function.

[0093] Specifically, the core component of the adaptive control unit is the adaptive motion strategy controller. Based on the real-time data obtained by the online monitoring unit and the data acquisition and processing unit as input, the motion strategy controller makes a control strategy for the motion of the actuator and sends execution commands through CAN communication to control the lifting platform on the shore that needs to be adjusted in height to perform lifting actions.

[0094] Specifically, the actuator control unit includes a programmable logic controller (PLC) and an operation box, which can realize manual operation and respond to control strategies initiated by the adaptive control unit.

[0095] Specifically, the early warning unit includes an alarm horn and an alarm light, which can remind operators to check dangerous points and alert people in the vicinity when danger occurs.

[0096] Based on the aforementioned highly adaptive adjustment system, a control strategy is proposed, including a manual control strategy, a semi-automatic control strategy, and a fully automatic control strategy.

[0097] The manual control strategy involves the operator adjusting the corresponding switch on the lifting cylinder of the control panel based on changes in sea level. The control panel sends an operation command to the programmable logic controller (PLC), which then issues a control command to the lifting cylinder, which executes the command. During this operation, the operator observes changes in the tilt angle sensor values ​​of both the local and adjacent shore-side lifting platforms. If the tilt angle is outside the ±7° range, the operator must manually adjust the lifting cylinders of both platforms until the control requirements are met. In case of danger, alarm horns and lights will activate.

[0098] The semi-automatic control strategy involves the operator adjusting the unloading channel elevation switch on the operation control box based on sea level changes. The positioning module obtains the current geographical location, and the operator retrieves sea level data from the publishing platform. A weighted average of the local data collected by the ranging module and the sea level data from the publishing platform is used to determine the actual sea level height, which is then sent to the adaptive motion strategy controller. Simultaneously, the data acquisition and processing units on each shore-side lifting platform send the collected current status data to the adaptive motion strategy controller and database via the CAN communication module. The data sent via the CAN communication module determines the number of shore-side lifting platforms currently in operation. Based on the collected data, the adaptive motion strategy controller generates a motion strategy for each shore-side lifting platform. This motion strategy includes control information such as the lifting cylinder's stroke, speed, and time. The programmable controller, receiving the control strategy, controls the lifting cylinders to ensure that all platform angles are within ±7°, enabling system height control for multiple shore-side lifting platforms. When a danger point is detected, alarm horns and lights activate, requiring the operator to eliminate the danger before normal operation can resume.

[0099] The fully automatic control strategy specifically refers to unattended operation. When the angle of the ramp is outside the range of ±7°, the adaptive motion strategy controller issues control commands without operator intervention. The programmable controller that receives the control strategy controls the lifting cylinder to work, so that the angle of all ramps is within the range of ±7°.

[0100] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
