Abstract
Description
Technical Field
[0001] This invention relates to the field of port shore power supply safety and communication protection technology, specifically a shore power communication cable connection safety protection system. Background Technology
[0002] Shore power systems are a crucial infrastructure in ports that provide shore-based power to berthed vessels. They transmit electricity from the shore power grid to ships via high-voltage or medium-voltage cables, thereby reducing pollution and noise from ship diesel generators. With the development of smart ports, shore power systems not only need to transmit electricity but also enable data exchange between ships and shore via communication cables, such as equipment status monitoring, energy metering, remote control, and fault diagnosis.
[0003] In existing technologies, shore power communication cables are typically connected via industrial interfaces or connectors, which presents the following problems:
[0004] Insufficient connection reliability means that in complex port environments (such as humidity, salt spray, vibration, and mechanical shock), communication cable connections are prone to loosening or poor contact, leading to communication interruptions.
[0005] With weak protection capabilities, traditional communication cable connection structures have limited waterproof, dustproof, and corrosion-resistant capabilities, making them susceptible to interface corrosion due to sea breezes, salt spray, or rainwater intrusion.
[0006] Lacking intelligent monitoring capabilities, existing systems typically rely solely on manual inspections, making it impossible to detect cable connection status, temperature changes, or abnormal tension in real time.
[0007] The safety risks are high. If the communication cable is accidentally detached or damaged, it may affect the remote control and safety management of the shore power system.
[0008] Therefore, there is an urgent need for a security protection system that can provide structural protection, condition monitoring, and intelligent early warning for the connection points of shore power communication cables. Summary of the Invention

Detailed Implementation
[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0040] Please see Figure 1-5This invention provides a technical solution: a shore power communication cable connection safety protection system, including a connection protection cylinder 1, an outer protection cylinder 2, and a connector protection structure. The outer protection cylinder 2 is sleeved on the outside of the connection protection cylinder 1. A detachable connector protection structure is located on the side of the connection protection cylinder 1. A cable end post 3 is provided on one side of the connection protection cylinder 1, and a connection disc 4 is provided on the other side. A connector insertion hole is opened in the middle of the outer side of the connection disc 4. A monitoring core box 5 for monitoring the connection status is provided on the outer wall of the connection protection cylinder 1. The connector protection structure includes two semi-circular pressure plates 6. An arc-shaped groove is opened in the middle of the inner side of the pressure plate 6, and a clamping structure is provided at the arc-shaped groove.
[0041] The clamping structure includes a clamping plate 7, an adjusting rod 8 connected to the outer side of the clamping plate 7, an insertion hole in the middle of the adjusting rod 8, a convex plate 9 correspondingly located on the outer wall of the pressure plate 6, a guide rod 10 on the convex plate 9, the inner end of the guide rod 10 passing through the insertion hole of the adjusting rod 8 and connecting to the interior of the pressure plate 6, an inflatable bladder 11 on the inner wall of the clamping plate 7, an insertion tube 12 on the inner wall of the pressure plate 6, and an insertion rod 13 correspondingly located on the outer side of the connecting disc 4. Inside the connecting protective cylinder 1, a connector protection structure for fixing the communication cable is provided. The connector protection structure includes a pressure plate 6, a clamping plate 7, and an adjusting rod 8. Two pressure plates 6 are respectively located on both sides of the communication cable connector. The clamping plate 7 supports and positions the pressure plates 6. The clamping force of the pressure plates 6 is adjusted by the adjusting rod 8, enabling the pressure plates 6 to stably clamp the communication cable connector, thereby preventing the communication cable from loosening under external pulling or vibration. An inflatable bladder 11 is provided on the inner side of the pressure plate 6. The inflatable bladder 11 can form a flexible buffer layer between the pressure plate 6 and the communication cable. When the communication cable is subjected to vibration or tension, the inflatable bladder 11 can absorb part of the impact force, thereby preventing the communication connector from being subjected to hard compression and improving the reliability of the communication cable connection structure.
[0042] A wire guide tube 14 is provided on the side of the outer protective cylinder 2, and a waterproof sealing ring 15 is provided on the inner side of the outer protective cylinder 2. The outer wall of the outer protective cylinder 2 is provided with an anti-salt spray coating 16. The wire guide tube 14 is located inside the outer protective cylinder 2, through which the communication cable enters the connecting protective cylinder 1. The wire guide tube 14 guides the communication cable, preventing it from bending or abrading when entering the protective structure.
[0043] A waterproof sealing ring 15 is provided at the connection between the outer protective cylinder 2 and the end cap 3. The waterproof sealing ring 15 is used to seal the connection gap, thereby preventing moisture from entering the interior of the protective structure. At the same time, an anti-salt spray coating 16 is provided on the inner wall of the outer protective cylinder 2. This coating can effectively resist salt spray corrosion in the port environment and improve the corrosion resistance of the entire protective structure.
[0044] The monitoring core box 5 includes an environmental monitoring module, a connection status detection module, and an intelligent control and early warning module. The intelligent control and early warning module, electrically connected to both the environmental monitoring module and the connection status detection module, analyzes and processes the collected data and triggers an alarm when an abnormal state occurs. A remote monitoring module, communicatively connected to the intelligent control and early warning module, uploads system operation data to the shore power management platform for remote monitoring and data storage. The monitoring core box 5 is located on one side of the outer protective cylinder 2 and is used for real-time monitoring of the communication cable connection status. The monitoring core box 5 internally houses the environmental monitoring module, the connection status detection module, the data analysis module, the intelligent control and early warning module, and the remote monitoring module.
[0045] The environmental monitoring module is used to collect environmental parameters near the communication cable connector in real time, including data such as temperature, humidity and salt spray concentration; the connection status detection module is used to detect changes in the contact resistance of the communication cable connector and changes in the tensile force borne by the communication cable, thereby determining whether the connection status of the communication cable is stable.
[0046] The data analysis module integrates and processes the data collected by the environmental monitoring module and the connection status detection module, and constructs a risk assessment model for communication cable connections. The intelligent control and early warning module determines whether there are any abnormalities in the communication cable connection status based on the risk assessment results. When the detected risk index exceeds a set threshold, the system will trigger an alarm device to provide an alert.
[0047] The environmental monitoring module includes a temperature sensor, a humidity sensor, and a salt spray corrosion sensor; it is used to monitor the environmental conditions of the area where shore power communication cables are connected in real time.
[0048] The connection status detection module includes: a plug position detection switch, a contact resistance detection unit, and a cable tension sensor; used to determine whether the communication cable is correctly connected and whether there is any looseness or excessive pulling.
[0049] The intelligent control and early warning module includes: a data acquisition unit, a data analysis unit, and an alarm control unit; it triggers an alarm when the following abnormal states are detected:
[0050] The communication cable is loose, the interface temperature rises abnormally, the humidity exceeds the set threshold, and the cable tension exceeds the safe range.
[0051] The remote monitoring module includes: a wireless communication unit, a data storage unit, and a remote monitoring platform interface; it is used to transmit system operation data to the shore power management center in real time.
[0052] The intelligent control and early warning module also includes a predictive analysis unit. This unit establishes a predictive model for the connection status of shore power communication cables based on historical monitoring data. This model is used to predict cable connection risks. The predictive model is built based on machine learning algorithms, and its input parameters include: ambient temperature data, ambient humidity data, contact resistance change data, and cable tensile force change data. Through multi-parameter fusion analysis, a cable connection risk index is calculated. When the connection risk index exceeds a set threshold, the system issues an early warning, thereby achieving predictive maintenance of shore power communication cable connection faults. The predictive analysis unit in the intelligent control and early warning module uses a multi-parameter fusion algorithm to assess the risk of communication cable connections. The calculation formula is as follows:
[0053] R = a1T + a2H + a3ΔRc + a4F
[0054] Where: R is the cable connection risk index, T is the interface temperature change rate, H is the ambient humidity index, ΔRc is the contact resistance change rate, F is the cable tensile force change value, and a1, a2, a3, and a4 are weighting coefficients. When R ≥ R0, the system determines that there is a potential fault risk in the communication cable connection and issues an early warning.
[0055] It also includes adaptive weight update algorithms.
[0056] The system dynamically optimizes the weights based on historical data:
[0057] a i (t+1)=a i (t)+η×e×x i in:
[0058] a i The weighting coefficient of the i-th monitoring parameter
[0059] η is the learning rate
[0060] e represents the prediction error.
[0061] x i This corresponds to the sensor data.
[0062] Through continuous training, the prediction model gradually adapts to different port environmental conditions.
[0063] In practical applications, the communication cable first passes through the conductor tube 14 into the outer protective tube 2 and connects to the interface of the connecting disc 4 in the connecting protective tube 1; then the cable connector is clamped and fixed by two pressure plates 6, and the clamping force is adjusted by the adjusting rod 8 to form a stable clamping structure between the pressure plates 6 and the cable connector.
[0064] Once the cable installation is complete, monitoring core box 5 will begin operation:
[0065] The temperature sensor detects changes in interface temperature in real time.
[0066] A humidity sensor detects the humidity of the external environment;
[0067] Salt spray sensors detect the degree of corrosive environments;
[0068] The contact resistance detection unit detects the resistance change of the connection terminals;
[0069] A tension sensor detects the stress on the cable.
[0070] The collected data is input to the data analysis unit through the data acquisition unit, and the cable connection risk index is calculated through a multi-parameter fusion algorithm.
[0071] When the system detects one of the following:
[0072] The contact resistance is abnormally high;
[0073] Interface temperature continues to rise;
[0074] The cable tension exceeds the safe range;
[0075] The ambient humidity is too high;
[0076] The system immediately triggers an audible and visual alarm through the alarm control unit and uploads the data to the shore power management platform via the wireless communication unit. Through long-term data accumulation, the predictive analysis unit can establish a predictive model of the communication cable connection status, enabling early warning of potential faults.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
