Problems solved by technology

The Three Gorges Ship Lock and Gezhouba No. 1 and No. 2 Ship Locks have a planar dimension of 280m×34m, and 4 to 6 ships can pass through each lock. Single-ship driving will enter the lock continuously from the pier, which takes a long time and the overall efficiency of passing the lock is not high. And the crew's driving level is uneven and there are potential safety hazards
[0004] However, how to further improve the efficiency of ships passing through the lock is still a technical bottleneck
In addition, with the large-scale ships passing through the locks of the Yangtze River, the maneuverability of large ships in the lock chamber is poor. There is a phenomenon that ships use floating bollards in the lock chamber to hang cables to brake, resulting in damage to the floating bollards. It is necessary to improve the accurate perception of ships passing through the locks. Navigation dynamics, realizing precise stopping control of large ships

Embodiment 1

[0039] see Figure 1-4 , a lock-passing ship formation cooperative stop ship control system, the lock-passing ship formation includes a pilot ship and multiple follower ships, the pilot ship stops automatically at the set virtual stop line, and the follower ships The pilot ship in front or other virtual stop line that follows the ship at a certain distance stops, and the real-time interaction between the two ships through the mobile network realizes the automatic stop control of multiple ships in the lock room; the control system includes a stop control unit , formation information interaction unit, ship status perception unit and shore-based service unit.

[0040] Further, the stop control unit is a set of stop control system installed on the ship, and the stop control unit judges the current navigation state according to the ship speed, ship position and related ship navigation status information, and calculates the next step of the ship. The car clock command controls the ...

Embodiment 2

[0081] Such as Figure 4 , adopting the control method for the pilot ship stopping by the cooperative stopping control system of the formation of ships passing the lock, comprising the following steps:

[0082] Step 1: The pilot ship perception unit transmits the collected navigation environment information and the ship's own navigation status information to the pilot ship host computer, and transmits the ship status information to the follower ship host computer and the shore-based unit through the mobile network;

[0083] Step 2: Through the analysis of the message and the message information sent by the lower computer of the pilot ship, the sliding mode control algorithm is used to perform control calculations to obtain the propeller speed required for the next step of the ship in order to realize the precise stop of the pilot ship;

[0084] Step 3: Through the serial port transceiver of the pilot boat, transmit the propeller speed command information required for the next ...

Embodiment 3

[0088] Such as Figure 4 A control method for following a ship to stop by adopting the cooperative stop control system of the formation of ships passing through the lock, comprising the following steps:

[0089] Step 1: Transmit the environmental data collected by the sensing unit of the following ship and the navigation status data of the following ship to the host computer of the pilot ship, and transmit the navigation status information to the shore-based unit through the mobile network. At the same time, the pilot ship transmits the ship's navigation information and pilot ship control instructions to the follower ship through the mobile network;

[0090] Step 2: Through the control command of the pilot ship, the navigation information of the pilot ship, and the message information sent by the lower computer of the follower ship, the sliding mode control algorithm is used for control calculation, and the following ship is obtained in order to realize the stable following sh...

Abstract

The invention provides a lockage ship formation cooperative ship stopping control system and a lockage ship formation cooperative ship stopping control method. The lockage ship formation comprises a pilot ship and a plurality of following ships, wherein the pilot ship automatically stops at a set virtual stop line, one of the following ships stops at the virtual stop line which keeps a certain distance from the pilot ship in front of the following ship or other following ships, and the two ships interact in real time through using a mobile network, so that automatic ship stopping control of the plurality of ships in a lock chamber is realized. The lockage ship formation cooperative ship stopping control system comprises a ship stopping control unit, a formation information interaction unit, a ship state sensing unit and a shore-based service unit.

Description

technical field [0001] The invention relates to the technical field of ship motion control, in particular to a control system and method for cooperative stopping of ship formations passing through locks. Background technique [0002] The navigable buildings of the Three Gorges-Gezhouba hub are key nodes of Yangtze River shipping, and their operating status is directly related to the smooth flow of the Yangtze River shipping, directly reflects the level of public services on the Yangtze River, and directly affects the economic and social construction and development along the river. The Three Gorges Ship Lock and Gezhouba No. 1 and No. 2 Ship Locks have a planar dimension of 280m×34m, and 4 to 6 ships can pass through each lock. Single-ship driving will enter the lock continuously from the pier, which takes a long time and the overall efficiency of passing the lock is not high. And the driving level of the crew is uneven and there are potential safety hazards. [0003] Since...
