Description

Technical Field

[0001] The invention belongs to the technical field of floating mooring posts, and particularly relates to a monitoring method for the safe working condition of a mooring post based on a fuzzy algorithm. Background Art

[0002] Existing floating mooring posts are important navigation facilities in the ship lock structure, and the safe operation and management of the ship lock are particularly important. During the water injection process of the ship lock, the floating barrels of the floating mooring posts will float upward along the guide rails. However, in actual work, there may be sundries such as garbage and floating weeds in the ship lock. When they float into the guide rails of the mooring posts, it will cause the floating barrels to be stuck and not rise or fall with the water level, resulting in the ship being tilted under stress and having a risk of capsizing. However, the existing floating mooring posts lack an efficient detection and alarm mechanism for safe working conditions, thus leading to huge potential safety hazards. Summary of the Invention

[0003] The purpose of the invention is to provide a monitoring method for the safe working condition of a mooring post based on a fuzzy algorithm, so as to solve the problem that the existing floating mooring posts lack an efficient detection and alarm mechanism for safe working conditions, thus leading to huge potential safety hazards.

[0004] The technical scheme adopted by the invention is as follows:

[0005] A monitoring method for the safe working condition of a mooring post based on a fuzzy algorithm, comprising the following steps:

[0006] (1) After several ships are respectively moored to the mooring posts on the corresponding floating barrels of the floating mooring posts through mooring ropes, water is injected into the ship lock or the ship lock discharges water outward;

[0007] (2) As the water level rises or falls, several groups of floating barrels move upward or downward correspondingly along the guide rails of the floating mooring posts, and the moving distance and moving speed in the moving direction of the floating barrels are continuously detected through sensors installed on each group of floating mooring posts per unit time;

[0008] (3) After the sensors collect and summarize the moving distance and moving speed data in the moving direction of each group of floating barrels of the floating mooring posts per unit time, operations are performed on the moving distance and moving speed in the moving direction of each floating barrel based on the fuzzy algorithm;

[0009] (4) When there is a fuzzy deviation range in which the moving distance and moving speed in the moving direction of a floating barrel exceed the moving distance and moving speed in the moving direction of other floating barrels after the operation, it is determined that the floating barrel is blocked from moving and a guide rail blockage anomaly occurs, and the sensor corresponding to the floating barrel immediately sends a signal of abnormal safety of the mooring post to the monitoring center.

[0010] Preferably, in the step (2), the sensor is a microwave ranging sensor. A square steel bracket is installed between the guide rails of the support frames on both sides of the floating mooring post, and the microwave ranging sensor is installed at the symmetric center of the square steel bracket. The transmitting end of the microwave ranging sensor vertically faces downward to one side of the floating drum of the floating mooring post. The microwave ranging sensor detects the distance from the floating drum in real time, and then acquires the moving distance and moving speed in the moving direction of the floating drum per unit time.

[0011] Preferably, in the step (2), the sensor is a pressure sensor. The pressure sensor is installed at the bottom of the floating drum. The pressure sensor collects the underwater pressure in real time, and then obtains the moving distance and moving speed in the moving direction of the floating drum per unit time through the current pressure value and the pressure change value per unit time.

[0012] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0013] 1. In the present invention, the moving distance and moving speed in the moving direction of the floating drum of each mooring group are measured and collected by the sensor, and the collected data is subjected to fuzzy algorithm operation. When the fuzzy deviation range of the moving distance and moving speed in the moving direction of the floating drum exceeds the moving distance and moving speed in the moving direction of other floating drums after the operation, it is determined that the floating drum is blocked and there is an abnormal blockage of the guide rail. The sensor corresponding to the floating drum immediately sends an abnormal signal to the monitoring center, issues a safety alarm, indicates that there is a safety risk for the ship, and indicates that there is an abnormality in the floating mooring post, thereby intelligently realizing the detection and prompt of the safety of the floating mooring post, and solving the problem that when there is an abnormal blockage of the guide rail in the existing floating mooring post, there is a lack of an efficient detection and alarm mechanism, which is likely to cause potential safety hazards.

[0024] In combination with the attached Figure 1 and the attached Figure 2, A monitoring method for the safe working condition of mooring posts based on a fuzzy algorithm, comprising the following steps:

[0025] (1) After several ships are respectively moored to the mooring posts on the corresponding floating mooring post floats through mooring ropes, water is injected into the ship lock or the ship lock discharges water outward;

[0026] (2) As the water level rises or falls, several groups of floats move upward or downward correspondingly along the guide rails of the floating mooring posts, and the moving distance and moving speed in the moving direction of the floats are continuously detected by sensors installed on each group of floating mooring posts per unit time;

[0027] (3) After the sensors collect and summarize the moving distance and moving speed data in the moving direction of each group of floating mooring post floats per unit time, the moving distance and moving speed in the moving direction of each float are calculated based on the fuzzy algorithm;

[0028] (4) When there is a fuzzy deviation range in which the moving distance and moving speed in the moving direction of a float exceed the moving distance and moving speed in the moving direction of other floats after the calculation, it is determined that the float is blocked from moving, and a guide rail blockage anomaly occurs, and the sensor corresponding to the float immediately sends a mooring post safety anomaly signal to the monitoring center.
