Description

Technical Field

[0001] The present invention relates to the technical field of port ship berthing protection, and particularly relates to a protection device and system for port ship berthing. Background Art

[0002] In recent years, with the development of the economic trade of various countries and the globalization of cargo transportation, it has driven the development around the world; among them, waterway transportation is an important part of cargo transportation. How to effectively ensure the transportation timeliness has increasingly become the focus of people's thinking. Among them, the wharf is a key link in waterway transportation. With the trend of ship enlargement, traditional wharves have been difficult to meet the ship berthing requirements, and each part of the structure needs to be strengthened to cope with the collision force generated by ship docking; nowadays, port wharves around the world are not only simple cargo transfer yards, but also an important and inseparable hub in cross-regional trade.

[0003] Existing port wharves usually install tires or other rubber products on the wharf to slow down the impact force when the ship docks. However, tires or other rubber products have low structural strength and insufficient anti-collision buffering performance. Long-term use is likely to cause permanent wear on the ship's side and the wharf. Moreover, with the development trend of port intelligent management, there are also obvious deficiencies in data monitoring, analysis and early warning in the existing protection measures, and it is impossible to evaluate and feedback the collision situation during the ship docking process in real time and accurately, making it difficult to meet the requirements of modern port refined management. Therefore, it is necessary to provide a protection device and system for port ship berthing to solve the above technical problems. Summary of the Invention

[0011] The sensing and acquisition module is connected to the pressure sensors and alarms of each protection device installed on the side wall of the dock through cables, and is used to receive the pressure data transmitted by the pressure sensors;

[0012] The central control unit is arranged in the control room of the port. The central control unit is internally provided with a pressure analysis unit, a verification trigger unit, a protection group analysis unit, and a storage module and a signal transceiver module connected thereto;

[0013] The pressure analysis unit is used to analyze the collision situation of the ship according to the pressure data to obtain a pressure analysis result, where the pressure analysis result includes the pressure value of the protection device, statistical indicators, pressure influence value, and pressure verification signal; the verification trigger unit is used to trigger the verification and analysis of the electrical parameters of the pressure sensor and the environmental monitoring data of the protection device after receiving the pressure verification signal to obtain a verification analysis result; among them, the verification analysis result includes the standard deviation value of any parameter in the electrical parameters and environmental monitoring data, the standard deviation mean value, the standard deviation fluctuation value, and the error influence value in the recent monitoring time zone; the protection group analysis unit is used to analyze the pressure analysis results of all protection devices on the side wall of the dock to obtain an alarm message; where the alarm message includes the pressure analysis result, the pressure influence value, the collision occurrence frequency, the protection times, the protection warning value, and the alarm signaling;

[0014] After receiving the alarm signaling, the signal transceiver module sends the alarm message to the monitoring terminal;

[0015] The storage module is used to receive and store various analysis results and information, and classify and organize them according to the date, dock number, and protection device number; among them, various analysis results include the pressure analysis result, the verification analysis result, and the alarm message.

[0016] Preferably, the collision situation of the ship is analyzed according to the pressure data, and the specific analysis is as follows:

[0017] Taking the current moment as the first moment, the time region within the preset time monitoring length before the first moment is marked as the pressure monitoring time zone; according to the pressure values collected by the pressure sensors within the pressure monitoring time zone, statistical indicators of the pressure values within the pressure monitoring time zone are calculated, including variance, maximum value, minimum value, and average value;

[0018] The pressure value at the current moment is weighted with all the indicators in its statistical indicators to obtain the pressure influence value;

[0019] A pressure warning threshold is set. If the pressure influence value is greater than its pressure warning threshold, it indicates that there may be a collision situation with the protection device, and a pressure verification signal is generated;

[0020] The pressure value, statistical indicators, pressure influence value, and pressure verification signal of the protection device are marked as the pressure analysis result.

[0024] The standard value of any parameter in the electrical parameters and environmental monitoring data is set, and the standard difference is obtained by subtracting any parameter in the electrical parameters and environmental monitoring data from its corresponding standard value; the recent monitoring time zone is set, and the average value and standard deviation of the standard differences within the recent monitoring time zone are calculated to obtain the standard deviation mean and standard deviation fluctuation value;

[0025] The standard differences, standard deviation mean, and standard deviation fluctuation value of all parameters of the electrical parameters and environmental monitoring data at the current moment are weighted to obtain the error influence value;

[0026] An error threshold is set. If the error influence value is less than its preset error threshold, it indicates that there is definitely an item colliding with the protection device and a collision situation occurs; if the error influence value is greater than or equal to its preset error threshold, it indicates that the collision situation that occurs is a false touch.

[0027] Preferably, the pressure analysis results of all the protection devices on the side wall of the dock are analyzed, specifically:

[0028] Taking the occurrence of a collision as the initial moment, marking the time regions before and after the initial moment with a set time length as the collision monitoring time zone, identifying the number and duration of collisions of all protective devices in the collision monitoring time zone, and calculating the collision occurrence frequency through the number and duration of collisions of the protective devices;

[0029] Recording the number of protective devices with collision occurrences is marked as the protection times;

[0030] Performing weighted processing on the pressure influence value, collision occurrence frequency, and protection times to obtain a protection warning value; setting a warning threshold. If the protection warning value is greater than its warning threshold, an alarm signal is generated to trigger the audible and visual alarm on the corresponding alarm device to remind the crew to pay attention to the docking status of the ship; marking the pressure analysis result, pressure influence value, collision occurrence frequency, protection times, protection warning value, and alarm signal as alarm information.

[0031] Preferably, the central control unit includes a registration unit and a remote monitoring unit;

[0033] The remote monitoring unit is used to connect to the central control unit through the signal transceiver module and display the pressure data, electrical parameters, environmental monitoring data, and alarm information of each protective device in the form of an interface.

[0034] Compared with the related technologies, a protective device and system for port ship berthing provided by the present invention has the following beneficial effects:

[0035] 1. The present invention realizes the comprehensive control of the port ship berthing protection system through the central control unit, accurately judges the collision situation through the pressure analysis unit, verifies and eliminates false judgments through the trigger unit, comprehensively evaluates the risk through the protection group analysis unit, and ensures the timely transmission of information through the signal transceiver module to generate a reliable warning, overcoming the deficiencies of existing protection measures in data monitoring, analysis, and warning, and meeting the requirements of modern port refined management.

[0036] 2. The present invention uses the pressure sensor to monitor the pressure situation of the ball head telescopic rod in real time. Once the ball head telescopic rod is over-extruded, the pressure sensor can quickly sense the pressure change and generate accurate pressure data. Based on the pressure data, when the pressure exceeds the set threshold, the alarm device can promptly issue an audible and visual alarm to remind the warning personnel to pay attention to the docking status of the ship so as to take corresponding measures in time to avoid the further deterioration of the collision accident.

[0037] 3. Through the cooperation of the straight guide sleeve and the ball-headed telescopic rod, the present invention can conduct the elastic force of the first spring. When the ship berths and collides, the first spring can effectively contract and deform, absorbing part of the impact force generated by the ship's impact and buffering the impact of the ship approaching the shore. At the same time, the synergistic effect of the inclined guide sleeve and the sliding telescopic rod further enhances the protection performance. The sliding telescopic rods in the four inclined guide sleeves can flexibly change their lengths according to the actual situation of the ship's side wall, causing the second spring to be compressed accordingly. This can not only better buffer the impact energy, but also ensure that the protective pad is always closely attached to the ship's side wall, effectively stabilizing the ship's attitude, assisting the ship to achieve a smooth berthing, and reducing the risk of permanent wear on the ship's side and the dock due to collision.

[0048] Please refer to Figures 1-6 A protective device for port ship berthing, which is applied to the side wall of a dock, includes a mounting plate 1. The mounting plate 1 is fixed to the side wall of the dock through connecting bolts. In the middle of the front end face of the mounting plate 1, a device shell 2 is fixedly installed through connecting bolts. A buffer assembly is arranged in the device shell 2. One end of a folding cover 3 is connected to the top surface of the device shell 2, and the other end of the folding cover 3 is connected to the middle of the back surface of a movable plate 4. The movable plate 4 is installed on the buffer assembly. A protective pad 5 is fixedly installed on the front end face of the movable plate 4. Through the cooperation of the protective pad 5 and the movable plate 4, it is convenient to directly bear the impact of the ship. The buffer assembly includes a straight guide sleeve 6. The straight guide sleeve 6 is a circular tubular structure and one end is fixedly connected to the middle of the front end face of the mounting plate 1. A ball head telescopic rod 7 is arranged in the straight guide sleeve 6. The ball head telescopic rod 7 is composed of a straight rod, a limiting piece and a ball head. The limiting piece is fixedly connected to one end of the straight rod, and the other end of the straight rod is fixedly connected with a ball head. A first spring 8 is arranged between the ball head telescopic rod 7 and the straight guide sleeve 6. Through the cooperation of the straight guide sleeve 6 and the ball head telescopic rod 7, it is convenient to conduct the elastic force of the first spring 8. A pressure sensor 9 is fixedly installed on the bottom surface of the ball head telescopic rod 7. An induction button is arranged on the back surface of the pressure sensor 9. A hoop sleeve 10 is sleeved on the ball head of the ball head telescopic rod 7. One end of the hoop sleeve 10 is fixedly connected to the movable plate 4. Through the cooperation of the ball head telescopic rod 7 and the hoop sleeve 10, it is convenient for the movable plate 4 to rotate.

[0049] In the present invention, four inclined guide sleeves 11 are evenly arranged around the front end face of the straight guide sleeve 6. A sliding telescopic rod 12 is arranged inside the inclined guide sleeve 11. A second spring 13 is arranged between the sliding telescopic rod 12 and the inclined guide sleeve 11. The front end of the sliding telescopic rod 12 is hinged with a slider 14. The slider 14 abuts against the back surface of the movable plate 4. The movable plate 4 is provided with a guide chute for cooperating with the slider 14. One side of the front end face of the mounting plate 1 is fixedly installed with an alarm 15. The alarm 15 is provided with an alarm lamp and a loudspeaker. Through the cooperation of the inclined guide sleeve 11 and the sliding telescopic rod 12, it is convenient to make the movable plate 4 fit the side wall of the ship.

[0050] For the port ship berthing protection device involved in the present invention, in actual use, the working principle is as follows:

[0051] First of all, it is necessary to power on the pressure sensor 9 and the alarm 15 to ensure that they are in a normal working state. Subsequently, the entire protection device is firmly installed on the dock shore through the connecting bolts. After the installation is completed, the device begins to perform the function of protecting the ship from collision;

[0052] When the ship enters the port, the ship gradually approaches the shore while continuously moving into the port. If the ship collides with the dock shore during the berthing process, at this time, the side wall of the ship will first come into contact with the protection pad 5. As the ship continues to squeeze, the protection pad 5 drives the movable plate 4 connected thereto to move backward, thereby squeezing the ball head telescopic rod 7 and causing the first spring 8 to contract and deform, so as to absorb part of the impact force generated by the ship collision;

[0053] At the same time, due to the different shapes of the ship side walls, the sliding telescopic rods 12 in the four inclined guide sleeves 11 will flexibly change their lengths according to the specific conditions of the ship side walls, causing the second spring 13 to be compressed accordingly. Through the coordinated action of the four inclined guide sleeves 11, not only the impact energy when the ship approaches the shore is further buffered, but also the protection pad 5 can always be closely attached to the ship side wall, thereby effectively stabilizing the ship's attitude and finally helping the ship to berth smoothly;

[0054] In addition, during the whole process, the pressure sensor 9 real-time monitors the pressure situation of the ball head telescopic rod 7. Once the ball head telescopic rod 7 is over-squeezed, causing the first spring 8 to contract and change, the pressure sensor 9 will sense the pressure change and generate corresponding pressure data. Based on this pressure data, it controls the alarm 15 to send a signal, driving the alarm lamp on the alarm 15 to light up and starting the loudspeaker, so as to remind the relevant warning personnel to pay attention to the ship docking state and take corresponding measures in time.

[0055] According to the above, the present invention also provides a port ship berthing protection system, including a sensing and acquisition module, a central control unit, and a monitoring terminal communicatively connected to the central control unit;

[0056] The sensing and acquisition module is connected to the pressure sensors 9 and alarms 15 of each protection device installed on the side wall of the dock through cables, and is used to receive the pressure data transmitted by the pressure sensors 9;

[0057] The central control unit is set in the control room of the port. The central control unit is built-in with a pressure analysis unit, a verification trigger unit, a protection group analysis unit, and a storage module and a signal transceiver module connected thereto;

[0058] The pressure analysis unit is used to analyze the collision situation of the ship according to the pressure data, and obtain a pressure analysis result, where the pressure analysis result includes the pressure value of the protection device, statistical indicators, pressure influence value and pressure verification signal; the verification trigger unit is used to trigger the verification and analysis of the electrical parameters of the pressure sensor and the environmental monitoring data of the protection device after receiving the pressure verification signal, and obtain a verification analysis result; among them, the verification analysis result includes the standard deviation value of any parameter in the electrical parameters and environmental monitoring data, the standard deviation mean value, the standard deviation fluctuation value and the error influence value in the recent monitoring time zone; the protection group analysis unit is used to analyze the pressure analysis results of all protection devices on the side wall of the dock to obtain an alarm message; among them, the alarm message includes the pressure analysis result, the pressure influence value, the collision occurrence frequency, the protection times, the protection warning value and the alarm signaling;

[0059] After receiving the alarm signaling, the signal transceiver module sends the alarm message to the monitoring terminal;

[0060] The storage module is used to receive various analysis results and information for storage, and classify and sort them according to the date, dock number, and protection device number; among them, various analysis results include pressure analysis results, verification analysis results and alarm messages.

[0061] In this application, the collision situation of the ship is analyzed according to the pressure data, and the specific analysis is as follows:

[0062] Taking the current moment as the first moment, the time area within the preset time monitoring length before the first moment is marked as the pressure monitoring time zone; according to the pressure value YL1 collected by the pressure sensor within the pressure monitoring time zone, calculate the statistical indicators of the pressure value within the pressure monitoring time zone, including variance YL2, maximum value YL3, minimum value YL4, and average value YL5;

[0063] The pressure value at the current moment is weighted with all the indicators in its statistical indicators to obtain a pressure influence value YL. The formula is expressed as: YL = YL1×y1 + YL2×y2 + YL3×y3 + YL4×y4 + YL5×y5; where, y1, y2, y3, y4, y5 respectively represent the weight influence factors corresponding to the pressure value at the current moment and the variance, maximum value, minimum value, and average value in the statistical indicators;

[0064] Set a pressure warning threshold. If the pressure influence value is greater than its pressure warning threshold, it indicates that there may be a collision with the protection device, and a pressure verification signal is generated.

[0065] Mark the pressure value, statistical index, pressure influence value, and pressure verification signal of the protection device as the pressure analysis result.

[0066] In this application, the electrical parameters of the pressure sensor and the environmental monitoring data of the protection device are verified and analyzed. The specific analysis is as follows:

[0067] Real-time monitor the electrical parameters of the pressure sensor, including the supply voltage, current stability, and voltage stability.

[0068] Obtain the environmental monitoring data at the set position of the protection device, including wind speed, light intensity, and temperature.

[0069] Set the standard value of any parameter in the electrical parameters and environmental monitoring data. Subtract the standard value from any parameter in the electrical parameters and environmental monitoring data to obtain the standard deviation value HG1. Set the recent monitoring time zone, and calculate the average value and standard deviation of the standard deviation values within the recent monitoring time zone to obtain the standard deviation mean value HG2 and the standard deviation fluctuation value HG3.

[0070] Perform weighted processing on the standard deviation value, standard deviation mean value, and standard deviation fluctuation value of all parameters of the electrical parameters and environmental monitoring data at the current moment to obtain the error influence value HG. The formula is as follows: Among them, i represents the number of parameters in the electrical parameters and environmental monitoring data, n represents the total number of parameters in the electrical parameters and environmental monitoring data, iHG1, iHG2, and iHG3 respectively represent the standard deviation value, standard deviation mean value, and standard deviation fluctuation value of parameter i in the electrical parameters and environmental monitoring data, and ih1, ih2, and ih3 respectively represent the weight influence factors corresponding to the standard deviation value, standard deviation mean value, and standard deviation fluctuation value of parameter i in the electrical parameters and environmental monitoring data.

[0071] Set an error threshold. If the error influence value is less than its preset error threshold, it indicates that there is definitely an item colliding with the protection device, and a collision situation occurs. If the error influence value is greater than or equal to its preset error threshold, it indicates that the collision situation is a false touch.

[0072] In this application, the pressure analysis results of all protection devices on the dock sidewall are analyzed. Specifically:

[0073] Taking the occurrence of a collision situation as the initial moment, marking the time region before and after the initial moment with a set time length as the collision monitoring time zone, identifying the number and duration of collision situations of all protection devices within the collision monitoring time zone, and calculating the collision occurrence frequency PZ through the number and duration of collision situations of the protection device.

[0074] The quantity mark of the protection devices that record collision situations is marked as the protection times FH;

[0075] The pressure influence value YL, the collision occurrence frequency, and the protection times are weighted to obtain the protection warning value YJ. The formula is expressed as: YJ = YL×r1 + PZ×r2 + FH×r3; where r1, r2, and r3 respectively represent the weights corresponding to the pressure influence value, the collision occurrence frequency, and the protection times; set a warning threshold. If the protection warning value is greater than its warning threshold, an alarm signal is generated to trigger the alarm light on the corresponding alarm device to light up and start the speaker to emit an audible and visual alarm, reminding the crew to pay attention to the ship's docking status; mark the pressure analysis result, the pressure influence value, the collision occurrence frequency, the protection times, the protection warning value, and the alarm signal as alarm information.

[0076] It should be noted that by setting the collision monitoring time zone, the collision situations of all protection devices within a specific time period are recorded in detail, covering the number and duration of collisions, so as to calculate the collision occurrence frequency and comprehensively reflect the collision dynamics during the ship docking process; recording the protection times can directly understand the range of protection devices affected by collisions, and combined with the pressure influence value, realize the accurate assessment of the overall protection status; the protection warning value is obtained by using the weighted processing method, scientifically distributing the weights of the pressure influence value, the collision occurrence frequency, and the protection times, and more accurately measuring the risk degree of ship berthing; compared with the set warning threshold, false alarms are effectively filtered to ensure the accuracy and timeliness of the alarm, enabling the crew to obtain key information in a timely manner and take corresponding measures. Integrating various data into alarm information is convenient for centralized management and subsequent analysis, providing data support for port operation management, and helping to optimize the ship docking process and the layout of protection devices;

[0077] Among them, the weights of the pressure influence value, the collision occurrence frequency, and the protection times are dynamically adjusted according to the actual operation situation of the port, such as the ship flow and weather conditions in different time periods, to make the weight coefficients in the weighted formula more in line with the actual needs.

[0078] Data analysis and in-depth mining:

[0079] Further analyze the data rules in the alarm information, such as the correlation between different ship types, load weights and collision situations, and provide more targeted suggestions for port facility improvement and ship operation specifications

[0080] In this application, the central control unit includes a registration unit and a remote monitoring unit;

[0081] The registration unit is used to receive the registration information submitted by the user and execute the registration process. After successful registration, a unique login account is generated for the user; the login account is used for remote login to the monitoring terminal;

[0082] The remote monitoring unit is used to connect to the central control unit through the signal transceiver module, and display the pressure data, electrical parameters, environmental monitoring data, and alarm information of each protection device in the form of an interface.

[0083] It should be noted that by setting up the registration unit and the remote monitoring unit, the usability and convenience of the system are improved. Port management personnel can use a smart terminal to log in to the monitoring terminal at any place to comprehensively monitor the dock site, realizing multi-faceted monitoring and management of the port ship berthing protection system, and adapting to the efficient and flexible operation mode of modern ports.

[0084] Those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present invention, which follow the general principles of the present invention and include known common knowledge or conventional technical means in the technical field not disclosed in this disclosure.
