Description

Technical Field

[0001] This invention relates to lock monitoring technology, and in particular to a smart monitoring system for floating mooring bollards in locks, its monitoring method, and storage medium. Background Technology

[0002] Currently, floating bollards are used in many large locks both domestically and internationally. However, most of these floating bollards are simply mechanical structures without the ability to collect and analyze physical information. They cannot monitor the position and stress of the floating bollards in real time, making it difficult to determine whether the bollards and related facilities are functioning properly. This results in a certain degree of lag in the operation and management of the locks, which in turn affects navigation safety. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide a smart monitoring system for floating bollards of a ship lock, as well as its monitoring method and storage medium, to ensure the safe operation of the ship lock.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The intelligent monitoring system for floating bollards in a lock according to the present invention includes a floating bollard, a stress-strain detector for monitoring the mooring force, an elevation detector for monitoring the height of the floating bollard, and a server. The stress-strain detector is installed on the floating bollard, the server is located in the lock chamber management center, and the elevation detector is installed on the top of the lock chamber. The detection data output terminals of the stress-strain detector and the elevation detector are respectively connected to the server's I / O interface. The server is used to receive, store, and analyze the real-time detection data sent by the elevation detector and the stress-strain detector.

[0005] Alternatively, the floating bollard consists of a column, a crossbeam fixed to the column, bolts fixed to the crossbeam, and a buoy fixed to the bottom of the column; several rollers are arranged vertically at intervals on the side of the column, and the column is connected to a vertical track fixed to the side wall of the lock chamber by means of the rollers.

[0006] The present invention implements a monitoring method for the intelligent monitoring system of the floating bollards in the lock, comprising the following steps: Step 1, downstream vessel upstream operating conditions; Step 1.1, Mooring Stage: The downstream vessel enters the lock chamber and, according to the operating procedures, fixes several cables to the bolts of the corresponding floating bollards. At this time, the stress and strain detectors on each floating bollard send stress detection signals to the server. If the stress values ​​of each floating bollard tend to be stable and consistent, it indicates that the vessel has successfully completed the mooring operation. Step 1.2, Gate Chamber Water Injection Stage: Step 1.2.1: The water level in the lock chamber begins to rise gradually. At this time, each floating bollard will rise along the vertical track as the water level rises. Simultaneously, the elevation detector sends elevation detection signals of each floating bollard to the server. The server compares the received elevation signals with the operating condition water level set by the lock chamber management center. If the elevation of each floating bollard rises synchronously and stably and is consistent with the operating condition water level set by the lock chamber management center, it indicates that each floating bollard is operating normally without any obstruction. Step 1.2.2: If the elevation of a certain floating bollard is less than the operating water level elevation set by the lock chamber management center, the server will indicate that the vertical track of the floating bollard may be blocked and send an alarm message to the lock management personnel. Step 1.2.3: If the stress value of a certain floating bollard suddenly approaches zero, the server will indicate that the bollard cable has fallen off or broken. At this time, the system will send an alarm message to the lock management personnel to warn the relevant vessels that the cable working status is abnormal. Step 1.2.4: If the stress value of each floating mooring bollard fluctuates beyond the set value of the operating condition, the server will indicate that the water flow in the lock chamber is complex and the water discharge hole of the water conveyance channel may not be discharging normally. An alarm message will be sent to the lock management personnel to remind them to check the water conveyance channel. Step 1.2.5: The server analyzes the stress-strain detection data of each floating bollard in real time. By analyzing the slope of the stress-strain curve and the characteristic data of strain amplitude, the server determines the structural health status of each floating bollard. If the strain of a floating bollard under the same stress state is significantly larger, it indicates that there is damage inside the structure of the floating bollard or that the structural material has degraded. The server sends an alarm message to the lock management personnel, prompting them to check the floating bollard in time. Step 1.2.6: After the lock chamber is filled with water, upstream vessels will exit the lock chamber in sequence. Step 2, Downstream vessel operating conditions: Step 2.1, Mooring Stage: The upstream vessel enters the lock chamber and, in accordance with the operating procedures, fixes several cables to the bolts of the corresponding floating bollards. At this time, the stress and strain detectors on each floating bollard send stress detection signals to the server. If the stress values ​​of each floating bollard tend to be stable and consistent, it indicates that the vessel has successfully completed the mooring operation. Step 2.2, Gate Chamber Discharge Stage: Step 2.2.1: The water level in the lock chamber begins to drop. At this time, each floating bollard will descend along the vertical track as the water level drops. Simultaneously, the elevation detector sends elevation detection signals of each floating bollard to the server. The server compares the received elevation signals with the operating condition water level set by the lock chamber management center. If the elevation of each floating bollard drops synchronously and stably and is consistent with the operating condition water level set by the lock chamber management center, it indicates that each floating bollard is operating normally without any obstruction. Step 2.2.2: If the stress value of a certain floating bollard suddenly approaches zero, the server will indicate that the cable of the floating bollard has fallen off or broken, and send an alarm message to the lock management personnel that the cable is in an abnormal working state. Step 2.2.3: If the stress value of each floating mooring bollard fluctuates beyond the set value of the operating condition, the server will indicate that the water flow in the lock chamber is complex and the water discharge hole of the water conveyance channel may not be discharging normally. An alarm message will be sent to the lock management personnel to remind them to check the water conveyance channel. Step 2.2.4: The server analyzes the stress and strain detection data of each floating bollard in real time. By analyzing the slope of the stress-strain curve and the characteristic data of strain amplitude, the server determines the structural health status of each floating bollard. If the strain of a floating bollard under the same stress state increases significantly, the server sends an alarm message to the lock management personnel, prompting them to check the floating bollard in time. Step 2.2.5: If the elevation of a certain floating bollard is greater than the operating water level elevation set by the lock chamber management center, the server will indicate that the vertical track of the floating bollard may be blocked and send an alarm message to the lock management personnel. Step 2.2.6: The lock chamber is discharged, and downstream vessels exit the lock chamber in sequence.

[0007] The present invention also provides a computer-readable storage medium, which may be in the form of a USB flash drive, a portable hard drive, a read-only memory (ROM), a random access memory (RAM), a disk, or an optical disk, etc.; the storage medium stores a computer program, and after the server's processor loads and runs the program, it can execute the various steps in the monitoring method of the intelligent monitoring system for floating bollards of locks.

[0008] This invention, based on Internet of Things (IoT) technology, integrates hardware and supporting software to collect and analyze the position and stress information of all floating bollards in a lock. Based on this information, it provides scientific and reasonable suggestions for the operation and management of the lock. Compared with existing floating bollards that are purely mechanical structures, this invention enables the timely detection and assessment of potential safety hazards, avoiding ship mooring problems caused by various factors, and providing a solid guarantee for the safe navigation of the lock.

[0019] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of the present invention, and detailed implementation methods and specific operation processes are given. However, the scope of protection of the present invention is not limited to the following embodiments.

[0020] It should be noted that, in the description of this invention, relational terms such as “first” and “second” are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0021] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] The intelligent monitoring system for floating bollards in locks described in this invention, such as Figure 5 , 6 As shown, the system includes a floating bollard 1, a stress-strain detector 2 for monitoring the mooring force, an elevation detector 3 (laser rangefinder) for monitoring the height of the floating bollard 1, and a server 4. The stress-strain detector 2 is installed on the floating bollard 1, the server 4 is located in the lock chamber management center 5, and the elevation detector 3 is installed on the top 6 of the lock chamber. The data output terminals of the stress-strain detector 2 and the elevation detector 3 are respectively connected to the I / O interface of the server 4. The server 4 is used to receive, store, and analyze the real-time detection data sent by the elevation detector 3 and the stress-strain detector 2, and recommend lock scheduling and management schemes for lock management personnel based on the analysis of the detection data.

[0023] Advantageously or exemplaryly, the floating bollard consists of a column 1.1, a crossbeam 1.2 fixed to the column 1.1, a cable bolt 1.3 fixed to the crossbeam 1.2, and a buoy 1.4 fixed to the bottom of the column 1.1; a stress-strain detector 2 is installed on the crossbeam 1.2, and several rollers (hidden in the figure) are arranged vertically at intervals on the side of the column 1.1, and the column 1.1 is connected to the vertical rail 7 fixed to the side wall of the lock chamber by the rollers.

[0024] like Figure 1 As shown, the monitoring method of the intelligent monitoring system for the floating bollards of the lock, as described in this invention, includes the following steps: Step 1, downstream vessels going upstream (lock chamber filling). Step 1.1, Mooring Stage: Downstream vessels enter the lock chamber, and according to the operating procedures, several cables are secured to the bolts of the corresponding floating bollards; for example... Figure 5 As shown in the attached diagram, in this embodiment, a vessel passing through the lock fixes three cables to bolts 1.3 of floating bollards 1#, 2#, and 3# respectively. At this time, the stress and strain detectors on floating bollards 1#, 2#, and 3# send stress detection signals to the server. If the stress values ​​of floating bollards 1#, 2#, and 3# tend to be stable and consistent, it indicates that the vessel passing through the lock has successfully completed the mooring operation. Figure 7 As shown; Step 1.2, Gate Chamber Water Injection Stage: Step 1.2.1: The water level inside the lock chamber begins to rise gradually. At this time, floating bollards #1, #2, and #3 will rise along the vertical track as the water level rises. Simultaneously, the elevation detector sends elevation detection signals for each floating bollard to the server. The server compares the received elevation signals with the operating condition water level set by the lock chamber management center. If the elevation of each floating bollard rises synchronously and stably and matches the operating condition water level set by the lock chamber management center, as shown in the attached diagram... Figure 8 As shown, this indicates that floating bollards #1, #2, and #3 are operating normally without obstruction. Step 1.2.2: If the elevation of a floating bollard is lower than the operating water level set by the lock chamber management center, the server will indicate that the vertical track of the floating bollard may be blocked, send an alarm message to the lock management personnel, and recommend a solution; Figure 2 As shown, this embodiment takes the case of a blockage in the vertical track of the No. 3 floating bollard as an example; Step 1.2.3: If the stress value of a floating bollard abruptly approaches zero, the server indicates that the bollard cable has detached or broken. At this time, the system will send an alarm message to the lock management personnel, recommend a handling solution, and simultaneously warn relevant vessels via broadcasts that the cable's working status is abnormal. Figure 3 As shown, this embodiment takes the case where the cable of the No. 3 floating bollard has come loose or broken as an example. Step 1.2.4: If the stress values ​​of each floating mooring bollard fluctuate beyond the set operating conditions, the server will indicate that the water flow in the lock chamber is complex and the drainage holes in the water conveyance channel may not be discharging normally. An alarm will be sent to the lock management personnel, reminding them to inspect the water conveyance channel. Figure 4 As shown, this embodiment takes the case where the stress detection values ​​sent by floating bollards #1, #2, and #3 fluctuate greatly and exceed the set value as an example; Step 1.2.5: The server analyzes the stress-strain detection data of each floating mooring bollard in real time. By analyzing the slope of the stress-strain curve and the characteristic data of strain amplitude, the structural health status of each floating mooring bollard is determined. If a floating mooring bollard shows a significant increase in strain under the same stress state, such as... Figure 9 As shown, this indicates that there is damage inside the structure of the floating bollard or that the structural materials have degraded; at this time, the server sends an alarm message to the lock management personnel, prompting them to check the floating bollard in time. Step 1.2.6: After the lock chamber is filled with water, the upstream vessels will exit the lock chamber in sequence. Step 2, Downstream vessel passage through the lock (lock chamber water discharge): Step 2.1, Mooring Stage: Upstream vessels entering the lock chamber will have several cables secured to the corresponding anchor bolts on each floating bollard, according to operating procedures. Figure 5 As shown in the attached diagram; in this embodiment, a vessel passing through the lock secures three cables to the bolts of floating bollards #1, #2, and #3 respectively. At this time, the stress-strain detectors on the floating bollards send stress detection signals to the server. If the stress values ​​of each floating bollard tend to be stable and consistent, it indicates that the vessel passing through the lock has successfully completed the mooring operation, as shown in the attached diagram. Figure 7 As shown; Step 2.2, Gate Chamber Discharge Stage: Step 2.2.1: The water level in the lock chamber begins to drop. At this time, floating bollards #1, #2, and #3 will descend along the vertical track as the water level drops. Simultaneously, the elevation detector sends elevation detection signals for each floating bollard to the server. The server compares the received elevation signals with the operating condition water level set by the lock chamber management center. If the elevations of each floating bollard drop synchronously and stably and match the operating condition water level set by the lock chamber management center, as shown in the attached diagram... Figure 8 The diagram shows the occurrence of unobstructed operation of floating bollards 1'#, 2'#, and 3'#. Step 2.2.2: If the stress value of a floating bollard abruptly approaches zero, the server indicates that the bollard cable has detached or broken. At this time, the system will send an alarm message to the lock management personnel, recommend a handling solution, and simultaneously warn relevant vessels via broadcasts that the cable's working status is abnormal. Figure 3 As shown, this embodiment takes the case where the cable of the No. 3 floating mooring bollard has come loose or broken as an example; Step 2.2.3: If the stress values ​​of each floating mooring bollard fluctuate beyond the set operating conditions, the server will indicate that the water flow in the lock chamber is complex and the drainage holes in the water conveyance channel may not be discharging normally. An alarm will be sent to the lock management personnel, reminding them to inspect the water conveyance channel. Figure 4As shown, this embodiment takes the case where the stress detection values ​​sent by floating bollards 1'#, 2'#, and 3'# fluctuate greatly and exceed the set value as an example; Step 2.2.4: The server analyzes the stress-strain detection data of each floating mooring bollard in real time. By analyzing the slope of the stress-strain curve and the characteristic data of strain amplitude, the structural health status of each floating mooring bollard is determined. If a floating mooring bollard shows a significant increase in strain under the same stress state, such as... Figure 9 As shown, this indicates that there is damage inside the structure of the floating bollard or that the structural materials have degraded; at this time, the server sends an alarm message to the lock management personnel, prompting them to check the floating bollard in time. Step 2.2.5: If the elevation of a floating mooring bollard is greater than the operating water level set by the lock chamber management center, the server will indicate that the vertical track of the floating mooring bollard may be blocked, send an alarm message to the lock management personnel, and recommend a handling solution; Figure 10 As shown, this embodiment takes the case of a blockage in the vertical track of the #3 floating bollard as an example; Step 2.2.6: The lock chamber is discharged, and downstream vessels exit the lock chamber in sequence.
