Abstract

The present invention discloses a method for automatically generating a virtual navigation mark on an electronic navigation channel chart according to water level change. According to the method, an automatic water level remote control detection device with GPS positioning is installed on a river reach; the automatic water level remote control detection device transmits detected water level information to a computer in a management center; the computer in the management center receives and releases the water level data; a terminal computer automatically generates a virtual navigation mark based on the existing electronic map layer information according to the water level data, and displays new virtual navigation mark information on the electronic navigation channel chart. With the present invention, the remote and real time monitoring of the water level of the river can be easily performed by the navigational fair department and the water conservancy department, the management department can real timely view the water level of the key point of the river, the virtual navigation mark can be automatically generated according to the water level change, and the safety guarantee is provided for ship navigation.

Description

technical field [0001] The invention relates to a river channel map, in particular to a method for automatically detecting, sending and receiving a river water level and automatically generating a virtual navigation mark according to the received water level. technical background [0002] A navigation mark is a kind of transportation facility installed in rivers, lakes and oceans to ensure safe navigation of ships, avoid dangerous areas, and guide navigation. It has played a great role in the development of shipping. As a large water country with vast sea area and numerous rivers and lakes, my country's shipping industry has developed rapidly. However, the development of shipping economy is restricted by the safety of navigation, which requires the navigation mark business to continuously innovate and adapt to the development of shipping economy. According to incomplete statistics, as of the end of 2008, my country has set up more than 40,000 navigation buoys of various typ...
