Combined dispatching simulation and analysis method for multi-line parallel locks

Abstract

The invention discloses a combined dispatching simulation and analysis method for multi-line parallel locks. The combined dispatching simulation and analysis method comprises the following steps: (1) determining the initial condition for combined lock dispatching simulation; (2) determining the navigation route and the position of a potential collision area; (3) establishing a lock running state mathematical model; (4) establishing a fleet movement mathematical model; (5) analyzing the lock running efficiency and the traffic condition of the collision area. According to the invention, the ship lockage dispatching is taken as the operations of two objects, namely locks and ships, and is adopted to establish the lock running state mathematical model and the fleet movement mathematical model, and mutual restriction of the two models is realized through the dispatching condition, so that during analysis on the running states of the multi-line parallel locks and the traffic condition of the navigation collision area, mutual effects between locks, locks and ships, and ships can be calculated and analyzed in the combined dispatching process of the multi-line parallel locks so as to provide reliable reference for the traffic organization in the combined dispatching process of the multi-line parallel locks.

Description

technical field [0001] The invention belongs to the field of water transportation, in particular to a simulation model of ship lock traffic organization. Background technique [0002] Ship lock is a kind of navigation facility widely used in cascade channelization projects of natural rivers. It has played an important role in promoting the upgrading of inland waterways in my country and ensuring the smooth progress of the construction of high-level waterway networks. In the past, due to the constraints of channel conditions, the inland river freight volume was small, and most of the hub constructions were single-line ship locks. There were few double-line and multi-line parallel ship locks, and the layout was mostly independent. For example, the three ship locks of Gezhouba were arranged separately, and No. 1 ship lock was located on the right bank of the river. , No. 2 ship lock is located on the right bank of the Sanjiang River, and No. 3 ship lock is located on the left b...

AI Technical Summary

Problems solved by technology

However, in the previous studies, due to the simple traffic flow of the lock, more attention was paid to the block problem of the lock chamber, and little attention was paid to the multi-level scheduling of multi-line parallel locks, let alone the traffic flow conflict near the lock.

At the same time, in the previous ship lock traffic organization simulation, the method based on the event process was generally adopted. The ship dispatching process and the ship lock operation process were included in one model at the same time. The model system was complex, which also increased the work of model debugging and modification difficulty
