Description

Technical Field

[0001] The present invention relates to the field of ship navigation and control technology, and in particular to a system and method for accurately controlling long-distance navigation of ships passing through locks based on big data analysis. Background Art

[0002] The anchorage for ships waiting for the lock is far away from the lock, and the navigation of ships passing through the lock is restricted by various factors, making it difficult to accurately control the time when the ship arrives at the lock, which brings two prominent problems: First, when the lock has the conditions for ships to enter the lock, no ships can pass, which reduces the number of lock operations and affects the navigation efficiency of the lock; second, when the ship arrives at the lock, it does not have the conditions for ships to enter the lock, and the ship cannot berth safely and achieve safe communication with the ships leaving the lock, which is prone to safety problems such as collisions between ships, and there are safety hazards. For this reason, the "General Design Specifications for Locks" clearly stipulates that a berthing section must be set up in the pilot channel to ensure the safe and efficient operation of the lock. However, when construction work is carried out in the pilot channel, the berthing section cannot be used normally, or the pilot channel of the lock does not have the conditions for setting up a berthing section, the operation of the lock and the safety of ships passing through the lock will be greatly affected, and there is no corresponding solution in the existing technology. Summary of the invention

After obtaining flow forecast data from the outside, the ship's navigation speed is calculated based on the channel flow velocity analysis, and the lock filling and discharging time and gate valve opening and closing time and the lock equipment operation time are calculated based on the lock water level analysis.

[0009] The data interaction processing module is used to analyze and calculate the remaining sailing time for the ship to reach the lock and the remaining time for the lock to meet the conditions for entering the lock; when the remaining sailing time for the ship to reach the lock is inconsistent with the remaining time for the lock to meet the conditions for entering the lock, the ship's sailing speed is re-analyzed and calculated, and the sailing speed adjustment instruction is transmitted to the ship behavior monitoring device through the communication module. Through the dynamic adjustment of the sailing speed, accurate control of the ship's navigation to the lock when the lock meets the conditions for entering the lock is achieved.

[0023] Embodiment 3: The downstream supporting anchorage of a hub ship lock is 18.7km away from the ship lock, and the downstream navigation channel is 3km long. At 8:00 on a certain day, the forecast inflow for that day is 7100m 3 / s. The vessel "XX" was waiting to pass the lock at the downstream supporting anchorage, and its lock passing plan was to go up the lock at 14:00 on the same day.

[0024] Step 1: Determine the ship's departure time.

[0025] 1.1, the big data analysis and processing module 3-1 determines the filling and releasing time of the ship lock (24 minutes) and the opening and closing time of the gate valve (6 minutes) according to the predicted flow.

[0026] According to the experience of ships entering and leaving the lock, it takes about 34 minutes for a ship to enter the lock and about 21 minutes for a ship to leave the lock.

[0027] According to calculations, the operation time of the ship lock is about 85 minutes; 1.2, the big data analysis and processing module 3-1 determines the recommended navigation speed from the anchorage to the entrance of the downstream pilot channel of the ship lock as 7.18 km / h according to the predicted flow, and the recommended navigation speed in the downstream pilot channel of the ship lock is 3.6 km / h; 1.3, the data interaction processing module 3-2 calculates that the sailing time from the anchorage to the lock is 206 minutes, and the corresponding departure time is 9 hours and 26 minutes (there are still 2.42 locks left for the ship to pass through the lock).

[0028] Step 2, ship sailing: The vessel set sail at 9:26 on the same day in accordance with the sailing order, with a cruising speed of 7.18km / h.

[0029] Step 3: Monitoring data collection: While the ship is sailing and the lock is running, the ship behavior monitoring device 1 collects the ship's navigation data in real time, and the ship's entry and exit state sensing device 2 collects the lock operation data in real time and transmits the data to the data interaction processing module 3-2. Specifically: at 11:15, the lock is ready for upstream ships to enter; at 12:40, the lock is ready for upstream ships to enter (5 minutes later than the planned lock time).

[0030] Step 4, data processing and calculation: 4.1, the data interaction processing module 3-2 uses the remaining distance of 11.9 km (10:23) from the position of the ship in the main channel to the entrance of the lower approach channel of the ship lock to calculate the time for the ship to arrive at the lower lock head as 149 minutes; 4.2, the data interaction processing module 3-2 uses the current lock operation time and the ship entry time and ship exit time to calculate the remaining lock operation time of the planned lock, which is 217 minutes.

[0031] Step 5: Ship speed analysis and judgment: The data interaction processing module 3-2 uses the remaining time of the planned lock operation (217 minutes) and the time it takes for the ship to sail to the lower lock (149 minutes) to calculate the time difference of 68 minutes. The data interaction processing module 3-2 determines that the ship should reduce its sailing speed to extend the time it takes for the ship to reach the lock, and calculates that the recommended speed for the remaining section from the ship to the downstream gate area of ​​the lock is 4.28 km / h, and the recommended speed for the section from the downstream gate area of ​​the lock to the lower lock is 3.6 km / h; Step 6, ship speed adjustment: The data interaction processing module 3-2 generates an adjustment instruction according to the new recommended speed and sends it to the ship through the communication module 3-3. The ship adjusts the navigation speed to 4.28 km / h according to the latest instruction. Step 7: The ship continues to sail at the latest recommended sailing speed: At 10:24, the ship was sailing at the recommended speed of 4.28 km / h, and the ship behavior monitoring device 1 continued to collect and monitor the navigation data of the ship.

[0032] At 12:40, the ship behavior monitoring device 1 collected the remaining distance of 2.2 km from the position of the ship in the main channel to the downstream gate area of ​​the ship lock. The ship entry and exit status sensing device 2 collected the opening and closing of the miter gate downstream of the ship lock, which was suitable for upstream ships to enter the lock, but was delayed by 5 minutes compared with the planned lock time, and transmitted the data to the data interaction processing module 3-2.

[0033] Step 8, data processing and calculation: 8.1, the data interaction processing module 3-2 uses the remaining distance of 2.2 km (12:40) from the position of the ship in the main channel to the entrance of the lower approach channel of the ship lock to calculate the time for the ship to arrive at the lower lock head as 81 minutes; 8.2, the data interaction processing module 3-2 uses the current lock operation time (85 minutes) and the ship entry time (34 minutes) and ship exit time (17 minutes) to calculate the remaining lock operation time of the planned lock round, which is 81 minutes.

[0034] Step 9: Ship speed analysis and judgment: The data interaction processing module 3-2 uses the remaining time of the planned lock operation (81 minutes) and the time for the ship to sail to the lower lock head (81 minutes) to calculate the time difference 0 minutes. The data interaction processing module 3-2 determines that the ship does not adjust the sailing speed.

[0035] The vessel continued to sail at the latest recommended speed of 4.28km / h and sailed at the recommended speed of 3.6km / h in the pilot channel downstream of the lock.

[0036] Step 10, vessel enters the lock: At 14:00, the ship sailed to the downstream head of the lock at the recommended speed; the miter gate downstream of the lock was fully opened, meeting the conditions for entering the lock.
