How to effectively ensure the timeliness of transportation has become a focus of people's thinking. Among them, docks are the key link in water transportation. With the trend of large-scale ships, traditional docks can no longer meet the berthing needs of ships. The structures of various parts need to be strengthened to cope with the collision force generated by the docking of ships. Nowadays, port terminals in various places are not only simple cargo transfer sites, but also important and inseparable hubs in cross-regional trade.

However, tires or other rubber products have low structural strength and insufficient anti-collision and buffering performance. Long-term use can easily cause permanent wear on the ship's side and dock. Moreover, with the development trend of intelligent port management, the existing protective measures also have obvious deficiencies in data monitoring, analysis and early warning.

[0010] As a preferred method, the collision situation of the ship is analyzed according to the pressure data, and the specific analysis is as follows: Taking the current moment as the first moment, marking the time area within the preset time monitoring length before the first moment as the pressure monitoring time zone; calculating the statistical indicators of the pressure value in the pressure monitoring time zone according to the pressure value collected by the pressure sensor in the pressure monitoring time zone, including variance, maximum value, minimum value, and average value; The pressure value at the current moment is weighted with all the indicators in its statistical indicators to obtain the pressure impact value; Set a pressure warning threshold. If the pressure impact value is greater than the pressure warning threshold, it means that the protective device may have a collision and a pressure verification signal is generated.

[0011] As a preferred embodiment, the electrical parameters of the pressure sensor and the environmental monitoring data of the protective device are verified and analyzed, and the specific analysis is as follows: Real-time monitoring of the electrical parameters of the pressure sensor, including supply voltage, current stability, and voltage stability; Obtain environmental monitoring data at the location where the protective device is set, including wind speed, light intensity, and temperature; Set the standard value of any parameter in the electrical parameter and environmental monitoring data, and subtract the corresponding standard value from any parameter in the electrical parameter and environmental monitoring data to obtain the standard deviation value; set the recent monitoring time zone, calculate the average value and standard deviation of the standard deviation value in the recent monitoring time zone to obtain the standard deviation mean and standard deviation fluctuation value; The standard deviation value, standard deviation mean value, and standard deviation fluctuation value of all parameters in the electrical parameters and environmental monitoring data at the current moment are weighted to obtain the error impact value; An error threshold is set.

[0015] 2. The present invention monitors the pressure condition of the ball head telescopic rod in real time through a pressure sensor. Once the ball head telescopic rod is over-squeezed, 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 can promptly issue an audible and visual alarm to remind the warning personnel to pay attention to the docking status of the ship so that corresponding measures can be taken in time to avoid further deterioration of the collision accident.

[0016] 3. The present invention can transmit the elastic force of the first spring through the cooperation of the straight guide sleeve and the ball head telescopic rod. When the ship berths and collides, the first spring can effectively shrink and deform to absorb part of the impact force generated by the collision of the ship and cushion the impact of the ship docking; at the same time, the synergistic effect of the inclined guide sleeve and the sliding telescopic rod further enhances the protection performance.

The ball head telescopic rod 7 is composed of a straight rod, a limit plate and a ball head. The limit plate is fixedly connected to one end of the straight rod, and a ball head is fixedly connected to the other end of the straight rod. 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, the elastic force of the first spring 8 is conveniently transmitted; a pressure sensor 9 is fixedly installed on the bottom surface of the ball head telescopic rod 7, and a sensing button is arranged on the back of the pressure sensor 9.

Through the cooperation of the ball head telescopic rod 7 and the hoop sleeve 10, the movable plate 4 is convenient to rotate.

[0023] In the present invention, four inclined guide sleeves 11 are evenly arranged around the front end surface of the straight guide sleeve 6, a sliding telescopic rod 12 is arranged in the inclined guide sleeve 11, a second spring 13 is arranged between the sliding telescopic rod 12 and the inclined guide sleeve 11, a slider 14 is hinged at the front end of the sliding telescopic rod 12, the slider 14 abuts against the back of the movable plate 4, and the movable plate 4 cooperates with the slider 14 to form a guide groove, an alarm 15 is fixedly installed on one side of the front end surface of the mounting plate 1, and an alarm light and a speaker are arranged on the alarm 15.

[0024] The working principle of the protective device for berthing ships in the port involved in the present invention is as follows in actual use: First, the pressure sensor 9 and the alarm 15 need to be powered on to ensure that they are in normal working condition. Then, the entire protective device is firmly installed on the dock shore by connecting bolts. After the installation is completed, the device begins to play the function of protecting ships from collision. When a ship enters the port, it gradually approaches the shore while continuing to move into the port. If the ship collides with the dock shore during the berthing process, the side wall of the ship will first contact the protective pad 5. As the ship continues to squeeze, the protective pad 5 drives the movable plate 4 connected thereto to move backward, thereby squeezing the ball head telescopic rod 7, causing the first spring 8 to shrink and deform, thereby absorbing part of the impact force generated by the collision of the ship; At the same time, due to the different shapes of the ship's sidewalls, 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's sidewalls, so that the second spring 13 is compressed accordingly. The coordinated action of the four inclined guide sleeves 11 not only further buffers the impact energy when the ship docks, but also enables the protective pad 5 to always fit closely to the ship's sidewall, thereby effectively stabilizing the ship's posture and ultimately helping the ship to dock smoothly. In addition, during the whole process, the pressure sensor 9 monitors the pressure condition of the ball head telescopic rod 7 in real time. Once the ball head telescopic rod 7 is over-squeezed, causing the first spring 8 to shrink and change, the pressure sensor 9 will sense the pressure change and generate corresponding pressure data. Based on this pressure data, the alarm 15 is controlled to send a signal, drive the alarm light on the alarm 15 to light up and start the speaker, so as to remind relevant warning personnel to pay attention to the docking status of the ship and take corresponding measures in time.

[0025] According to the above, the present invention also provides a protection system for ship mooring in a port, including a sensor collection module, a central control unit and a monitoring terminal connected to the central control unit for communication; The sensing acquisition module is connected to the pressure sensors 9 and the alarm 15 of each protective device installed on the side wall of the dock through cables, and is used to receive the pressure data transmitted by the pressure sensor 9; The central control unit is set in the control room of the port. It has built-in pressure analysis unit, verification trigger unit, protection group analysis unit and storage module and signal transceiver module connected thereto; A pressure analysis unit is used to analyze the collision situation of the ship according to the pressure data to obtain the pressure analysis result, wherein the pressure analysis result includes the pressure value of the protective device, statistical indicators, pressure impact value and pressure verification signal; a verification trigger unit is used to trigger the verification analysis of the electrical parameters of the pressure sensor and the environmental monitoring data of the protective device after receiving the pressure verification signal to obtain the verification analysis result; wherein the verification analysis result includes the standard deviation value of any parameter in the electrical parameters and the environmental monitoring data and the standard deviation mean value, standard deviation fluctuation value and error impact value in the recent monitoring time zone; a protection group analysis unit is used to analyze the pressure analysis results of all the protection devices on the side wall of the dock to obtain alarm information; wherein the alarm information includes the pressure analysis result, pressure impact value, collision frequency, protection number, protection warning value and alarm signaling; After receiving the alarm signal, the signal transceiver module sends the alarm information to the monitoring terminal; The storage module is used to receive various analysis results and information for storage, and to classify and organize them according to date, dock number, and protective device number; among them, various analysis results include pressure analysis results, verification analysis results, and alarm information.

[0026] In this application, the collision of ships is analyzed based on pressure data, and the specific analysis is as follows: The current moment is taken as the first moment, and 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 in the pressure monitoring time zone, the statistical indicators of the pressure value in the pressure monitoring time zone are calculated, including the variance YL2, the maximum value YL3, the minimum value YL4, and the average value YL5; The pressure value at the current moment is weighted with all the indicators in its statistical indexes to obtain the pressure impact value YL, which is expressed by the formula: ; Among them, y1, y2, y3, y4, and y5 represent the weighted influencing factors corresponding to the variance, maximum value, minimum value, and average value of the pressure value and statistical indicators at the current moment, respectively; Set a pressure warning threshold. If the pressure impact value is greater than the pressure warning threshold, it means that the protective device may have a collision and a pressure verification signal is generated. The pressure value, statistical index, pressure impact value and pressure verification signal of the protective device are marked as pressure analysis results.

[0027] In this application, the electrical parameters of the pressure sensor and the environmental monitoring data of the protective device are verified and analyzed. The specific analysis is as follows: Real-time monitoring of the electrical parameters of the pressure sensor, including supply voltage, current stability, and voltage stability; Obtain environmental monitoring data at the location where the protective device is set, including wind speed, light intensity, and temperature; Set the standard value of any parameter in the electrical parameter and environmental monitoring data, and subtract the corresponding standard value from any parameter in the electrical parameter and environmental monitoring data to obtain the standard deviation value HG1; set the recent monitoring time zone, calculate the average value and standard deviation of the standard deviation value in the recent monitoring time zone to obtain the standard deviation mean value HG2 and the standard deviation fluctuation value HG3; The error impact value HG is obtained by weighting the standard deviation value, standard deviation mean value, and standard deviation fluctuation value of all parameters in the electrical parameters and environmental monitoring data at the current moment. The formula is: ; Wherein, i represents the number of the parameter in the electrical parameter and environmental monitoring data, n represents the total number of parameters in the electrical parameter and environmental monitoring data, iHG1, iHG2, iHG3 represent the standard deviation value, standard deviation mean, and standard deviation fluctuation value of parameter i in the electrical parameter and environmental monitoring data, respectively, and ih1, ih2, ih3 represent the weight influence factors corresponding to the standard deviation value, standard deviation mean, and standard deviation fluctuation value of parameter i in the electrical parameter and environmental monitoring data, respectively; An error threshold is set. If the error impact value is less than the preset error threshold, it indicates that an object has collided with the protective device and a collision has occurred. If the error impact value is greater than or equal to the preset error threshold, it indicates that the collision is an accidental touch.

[0028] In this application, the pressure analysis results of all protective devices on the dock sidewall are analyzed, specifically: The occurrence of a collision is taken as the initial moment, and the time zone within a set time length before and after the initial moment is marked as the collision monitoring time zone. The number and duration of collisions of all protective devices in the collision monitoring time zone are identified, and the collision frequency PZ of the protective devices is calculated according to the number and duration of collisions of the protective devices. The number of protective devices that have collisions is recorded as the number of protection times FH; The pressure impact value YL, collision frequency, and protection times are weighted to obtain the protection warning value YJ, which is expressed by the formula: ; Among them, r1, r2, and r3 represent the weights corresponding to the pressure impact value, collision frequency, and protection times respectively; set the 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 and start the speaker to emit an audible and visual alarm to remind the crew to pay attention to the docking status of the ship; mark the pressure analysis results, pressure impact value, collision frequency, protection times, protection warning value, and alarm signal as alarm information.

[0029] It should be noted that by setting the collision monitoring time zone, the collision conditions of all protective devices within a specific time period are recorded in detail, covering the number and duration of collisions, so as to calculate the frequency of collisions and fully reflect the collision dynamics during the ship's berthing process; recording the number of protection times can intuitively understand the scope of protective devices affected by the collision, and comprehensively evaluate the overall protection status by combining the pressure impact value; using a weighted processing method to obtain the protection warning value, scientifically allocate the weights of the pressure impact value, the frequency of collisions and the number of protection times, and more accurately measure the risk level of the ship's berthing; compared with the set warning threshold, effectively filter out false alarms, ensure the accuracy and timeliness of the alarm, enable the crew to obtain key information in a timely manner, take countermeasures to integrate various data into alarm information, facilitate centralized management and subsequent analysis, provide data support for port operation management, and help optimize the ship's berthing process and the layout of protective devices; Among them, the weights of the pressure impact value, collision frequency, and protection times are dynamically adjusted according to the actual operation of the port, such as ship flow and weather conditions in different periods, to make it more in line with actual needs.

[0030] Data analysis and in-depth mining: Further analysis of the data patterns in the alarm information, such as the correlation between different ship types, loads and collision situations, can provide more targeted suggestions for port facility improvements and ship operation specifications. In this application, the central control unit includes a registration unit and a remote monitoring unit; The registration unit is used to receive the registration information submitted by the user and execute the registration process. After the registration is successful, a unique login account is generated for the user; the login account is used to remotely log in to the monitoring terminal; 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.

[0031] It should be noted that the availability and convenience of the system are improved by setting up a registration unit and a remote monitoring unit. Port management personnel can use a smart terminal to log in to the monitoring terminal anywhere to conduct a comprehensive monitoring of the terminal site, thus realizing multi-faceted monitoring and management of the port's ship berthing protection system, adapting to the efficient and flexible operation mode of modern ports.

The specific analysis is as follows: Real-time monitoring of the electrical parameters of the pressure sensor, including supply voltage, current stability, and voltage stability; Obtain environmental monitoring data at the location where the protective device is set, including wind speed, light intensity, and temperature; Set the standard value of any parameter in the electrical parameter and environmental monitoring data, and subtract the corresponding standard value from any parameter in the electrical parameter and environmental monitoring data to obtain the standard deviation value; set the recent monitoring time zone, calculate the average value and standard deviation of the standard deviation value in the recent monitoring time zone to obtain the standard deviation mean and standard deviation fluctuation value; The standard deviation value, standard deviation mean value, and standard deviation fluctuation value of all parameters in the electrical parameters and environmental monitoring data at the current moment are weighted to obtain the error impact value; An error threshold is set. If the error impact value is less than the preset error threshold, it indicates that an object has collided with the protective device and a collision has occurred. If the error impact value is greater than or equal to the preset error threshold, it indicates that the collision is an accidental touch.

8. A protection system for berthing ships in a port according to claim 5, characterized in that: The pressure analysis results of all protective devices on the dock side walls are analyzed, specifically: The occurrence of a collision is taken as the initial moment, and the time zone within a set time length before and after the initial moment is marked as the collision monitoring time zone. The number and duration of collisions of all protective devices in the collision monitoring time zone are identified, and the collision frequency of the protective devices is calculated based on the number and duration of collisions of the protective devices. The number of protective devices that have collisions is recorded as the number of protection times; The pressure impact value, collision frequency, and protection number are weighted to obtain the protection warning value; a warning threshold is set. If the protection warning value is greater than the warning threshold, an alarm signal is generated to trigger the sound and light alarm on the corresponding alarm to remind the crew to pay attention to the docking status of the ship; the pressure analysis results, pressure impact value, collision frequency, protection number, protection warning value, and alarm signal are marked as alarm information.
