[0002] Liquid chemical terminals are used for loading and unloading of various hazardous chemicals, cleaning of pipelines and other operations. The liquid loading and unloading system of traditional terminals is a semi-intelligent system. Before carrying out liquid loading and unloading operations at the terminal, workers are required to manually open the locking mechanism at the bottom of the loading arm column, and then operate the remote control to make the three-dimensional joint of the loading arm close to the medium outlet flange of the ship. Then, they board the ship and approach the flange interface of the loading arm, remove the flange blind plate, and finally operate the loading arm to dock with the ship flange. After successful docking, the adjustable legs are manually lowered to the deck surface for liquid transfer and transportation.

[0042] The intelligent loading and unloading system includes an acquisition module, an analysis module, a control module and an early warning module. The acquisition module is electrically connected to the flow meter, camera 1 11, temperature sensor 12 and camera 2 13. The acquisition module is used to collect and record relevant data on the flow rate, the end image of the cross arm 83 and the temperature during fluid loading and unloading. The analysis module is used to perform comparative analysis based on the collected relevant data. The control module is electrically connected to the drive unit 1 34, the emergency detachment head 82, the hydraulic cylinder 84, the drive unit 2 810 and the drive unit 3 811. The control module is used to control the drive and the rapid detachment of the connecting arm 81 in an emergency. The early warning module is used for early warning and alarm prompts.

[0043] The specific working method of the intelligent loading and unloading system is:

[0044] Step 1: The control module controls the connector 8 to automatically dock with the ship medium flange.

[0045] Specifically, the acquisition module collects the images taken by the camera 11, identifies and calculates the distance and height difference to the ship medium flange, controls the drive unit 3 811 to open the cover 89 at the end of the cross arm 83, and then starts the drive unit 34 to drive the counterweight block 32 and the counterweight block 2 33 to slide on the connecting block 31, adjusts the counterweight position, so that the connecting head 8 is close to the ship medium flange and has the same height, and finally controls the hydraulic cylinder 84 and the drive unit 2 810 to start, so that the cross arm 83 is automatically docked with the ship medium outlet flange.

[0046] Step 2: The acquisition module acquires and identifies the acquisition image of the second camera 13 to determine whether there is a leak.

[0047] Specifically, after the automatic docking is completed, the valves on the ship, loading and unloading arms and the dock pipeline system are opened, and the pressure difference of the liquid medium is used for loading and unloading. After a certain period of time, when the loading and unloading is normal, the acquisition module collects and identifies the acquisition image of the camera 2 13, identifies whether there is liquid dripping at the docking point between the connector 8 and the ship's docking flange, and determines the color of the dripping liquid.

[0048] Case 1: In the shot, the liquid drips at an equal time and the droplets are transparent and colorless, indicating raindrops falling on a rainy day, with no leakage.

[0049] Case 2: In the picture, the liquid drips at the same time, but the droplets are not transparent and have color. This is a slight leakage of the liquid, which is caused by an abnormal sealing ring at the joint.

[0050] Case 3: In the shooting picture, the liquid falls continuously in a columnar shape and the droplets are opaque and colored, which is a serious leakage caused by the overall abnormality of the connector 8;

[0051] In case 2 and 3, feedback is given to the early warning module, the valves on the ship, loading and unloading arm and terminal pipeline system are automatically closed and the connection between the connector 8 and the ship's medium flange is disconnected. Feedback is given to the early warning module, and the staff adjusts, replaces the sealing ring or repairs the connector 8. The control module controls the drive unit 2 810 to start and repeat steps 1 and 2 again, only once. If the result remains unchanged at this time, feedback is given to the early warning module again, and the staff replaces the connector 8 and performs manual docking.

[0052] Step 3: The acquisition module collects the flow rate detected by the flow meter during normal loading and unloading, the images captured by camera 1 11 and camera 2 13, and the temperature data detected by the temperature sensor 12, and feeds them back to the analysis module for analysis and judgment.

[0053] Specifically, the analysis module records the actual flow rate during liquid loading and unloading as L, and the highest temperature measured in the actual temperature as T. The analysis module also sets the loading and unloading flow limit and loading and unloading temperature limits .

[0054] exist , When , is the optimal loading and unloading flow rate and loading and unloading temperature, n is the interval coefficient of the optimal loading and unloading flow rate, and m is the interval coefficient of the optimal loading and unloading temperature.

[0055] exist When the loading and unloading flow is small, if , which is caused by the low loading and unloading temperature causing the sealing ring to deform or shift in position, and is fed back to the early warning module, and repeated adjustments are made according to the processing method of situation 2. Only repeat once; if at this time , the loading and unloading temperature is normal, the docking is normal, and the pressure during loading and unloading is increased, thereby indirectly increasing the loading and unloading flow rate and ensuring the stability during loading and unloading; if at this time , for this reason, the loading and unloading temperature is high and the docking is normal, but there may be a fire hazard. The valves on the ship, loading and unloading arm and terminal pipeline system are automatically closed to avoid safety accidents, and feedback is given to the early warning module for alarm prompts.

[0056] exist When the loading and unloading flow is large and the connection is normal, if , because the loading and unloading temperature is low, the acquisition module continuously acquires the images of camera 1 11 and camera 2 13, and when situation 2 and situation 3 in step 2 occur, feedback is given to the control module to control the emergency detachment head 82 to separate, and automatically close the valves on the ship, loading and unloading arm and dock pipeline system to avoid the gradual expansion of the leakage at the docking point due to the large flow rate during loading and unloading, and even the rupture of the docking point due to the large flow rate and pressure, thereby ensuring the safety of fluid loading and unloading; if at this time , to ensure the normal loading and unloading temperature, reduce the pressure during loading and unloading, thereby indirectly reducing the loading and unloading flow, ensuring the stability and safety during loading and unloading, and at the same time feedback to the early warning module for alarm prompts; if at this time Therefore, the loading and unloading temperature is high and there may be a fire hazard. The acquisition module continuously collects the images of camera 11 and camera 2 13. When a fire point appears in the image, it is fed back to the control module to control the emergency separation head 82 to separate and automatically close the valves on the ship, loading and unloading arm and terminal pipeline system to avoid fire, thereby ensuring the safety of fluid loading and unloading, and at the same time feeding back to the early warning module for alarm prompts.

[0057] Through the above steps, the automatic docking and limiting of the connecting head 8 and the ship medium flange can be achieved to prevent leakage of liquid media and ensure the docking effect. At the same time, it can also monitor and warn during loading and unloading, standardize operations, reduce the impact of uncertainty caused by human factors, improve the safety of loading and unloading, and realize intelligent unmanned loading and unloading of liquid chemical terminals.

The analysis module also sets a loading and unloading flow limit. and loading and unloading temperature limits ; exist , When is the optimal loading and unloading flow rate and loading and unloading temperature, n is the interval coefficient of the optimal loading and unloading flow rate, and m is the interval coefficient of the optimal loading and unloading temperature; exist When the loading and unloading flow is small, , which is caused by the deformation or position displacement of the sealing ring due to low loading and unloading temperature, and is fed back to the early warning module, and repeated adjustments are made according to the processing method of situation 2 only once; at this time , the loading and unloading temperature is normal, the docking is normal, the pressure during loading and unloading is increased, thereby indirectly increasing the loading and unloading flow rate and ensuring the stability during loading and unloading; at this time , because the loading and unloading temperature is high and the docking is normal, but there may be a fire hazard, the valves on the ship, loading and unloading arm and terminal pipeline system are automatically closed to avoid safety accidents, and feedback is sent to the early warning module for alarm prompts; exist When the loading and unloading flow is large and the connection is normal, , because the loading and unloading temperature is low, the acquisition module continuously acquires the images of camera 1 (11) and camera 2 (13), and when situation 2 and situation 3 in step 2 occur, feedback is given to the control module to control the emergency separation head (82) to separate, and automatically close the valves on the ship, loading and unloading arm and dock pipeline system, so as to avoid the gradual expansion of the leakage at the docking point due to the large flow rate during loading and unloading, or even the occurrence of the docking point breaking due to the large flow rate and pressure, thereby ensuring the safety of fluid loading and unloading; at this time , the loading and unloading temperature is normal, the pressure during loading and unloading is reduced, thereby indirectly reducing the loading and unloading flow, ensuring the stability and safety during loading and unloading, and at the same time feeding back to the early warning module for alarm prompts; at this time Therefore, the loading and unloading temperature is high and there may be a fire hazard. The acquisition module continuously collects the images of camera 1 (11) and camera 2 (13). When a fire point appears in the image, it is fed back to the control module to control the emergency separation head (82) to separate and automatically close the valves on the ship, loading and unloading arm and terminal pipeline system to avoid fire, thereby ensuring the safety of fluid loading and unloading, and at the same time feeding back to the early warning module for alarm prompts.
