Harbor tug dispatching and charging method

Abstract

The invention discloses a harbor tug dispatching and charging method. The harbor tug dispatching and charging method comprises the following steps: a tug end acquires tug state data through a tug state acquiring module; the tug end obtains existing tug position information through a GPS (global positioning system) module; the tug end determines working time of the tug at different positions through a processing module; the tug end transmits working time information of the tug at different positions to a dispatching end through a first communication module; a dispatching end receives working time information, transmitted from the tug end, of the tug at different positions through a second communication module; the dispatching end obtains client information by combining the working time information, transmitted from the tug end, of the tug at different positions with a client information database as well as a corresponding relationship of different positions and the client information, and calculates cost corresponding to the working time according to the cost database through a calculating module. The harbor tug dispatching and charging method is high in charging efficiency, labor-saving and high in accounting accuracy and difficultly makes mistakes.

Description

technical field [0001] The invention relates to a port tugboat dispatching and charging method. Background technique [0002] Tugboats are used to tow ships without self-propelled capabilities, wooden rafts, or to assist large ships to enter and leave ports, to leave the dock, or to rescue ships in distress at sea. The tugboat does not have a cargo hold for loading cargo. The propulsion main engine and towing equipment with high power have greater towing capacity, and are generally divided into ocean tugboats, port tugboats and inland river tugboats; port tugboats are used in harbors, with short hulls and flexible maneuvering. [0003] The existing technology often calculates the operation cost of port tugboats manually, which is not only inefficient and wastes manpower, but also has low accounting accuracy and is prone to errors. Contents of the invention [0004] In view of the above problems, the present invention develops a port tugboat dispatching and billing method....
