Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation assisting device, and more particularly to a navigation assisting device which superimposes weather and sea condition information on an electronic nautical chart so as to ensure selection of an optimum route for a navigating ship and easy decision of maneuvering.

[0002]

2. Description of the Related Art Conventionally, when a ship navigates, as shown in FIG. 2, the position of the ship on the electronic chart displayed on the electronic chart display device 101 or the ship position data input from the navigation device 102 is displayed on the chart. With respect to the own ship position plotted by the operator 105, the navigation officer has determined the route and operation of the ship by referring to a plurality of types of weather maps on the facsimile recording paper 104 output from the weather facsimile receiver 103.

[0003]

This conventional navigation assistance method is carried out by comparing both an electronic chart or nautical chart and a plurality of types of weather charts on facsimile paper, but the scale of both charts is used. Is different,
There is a problem that it is difficult to grasp the surrounding weather and sea conditions with respect to the current position of the ship due to different drawing methods.

Further, in the case of determining the route and maneuvering of a ship, there is a problem that a great deal of labor is required to write necessary weather and sea condition data from a plurality of weather maps on the nautical chart, if necessary.

The object of the present invention is to solve the above-mentioned problems,
It is an object of the present invention to provide a navigation support device that automates the superimposed display of the surrounding weather and sea conditions with respect to the current ship position and makes it extremely easy to select a route and make a maneuvering decision.

[0006]

A navigation support device according to the present invention comprises a facsimile data input section for converting and outputting weather map facsimile data of grayscale image data output by a weather facsimile receiver into weather map graphic data, and various navigation instruments. Input the ship position data output by the compound navigation system that determines the ship position based on the acquired data and the weather map graphic data, and of the electronic nautical chart data related to the area to be displayed based on the display range and scale specified by the operator. A data processing unit that performs editing and performs position matching processing between the weather chart graphic data and the edited electronic nautical chart data; and an input setting unit that sets the contents designated by the operator and inputs the contents to the data processing unit. An electronic chart data file storing the electronic chart data, And it has a configuration in which a display unit for displaying the processing result and the serial data processor.

Further, in the navigation support device of the present invention, the display unit displays an electronic nautical chart of a corresponding display area and a plurality of types of weather map graphic data output from the facsimile data input unit, which is selected by an operator. , And at least based on the ship position data and including the ship position data so as to be superimposed and displayed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. The embodiment shown in FIG. 1 is a navigation assistance device 1 of the present invention, a weather facsimile receiver 2 for receiving weather map facsimile data, a compound navigation device 5, and a plurality of navigation devices for providing navigation data to the compound navigation device 5. Loran C receiver 9, GPS receiver 10, NNSS receiver 11,
It has a configuration including a gyro compass 12 and a Doppler log 13.

The navigation assistance device 1 also includes a facsimile data input unit 3 for converting weather map facsimile data into weather map graphic data, and various input data to process desired input data on a desired electronic chart for a desired area. A data processing unit 4 for performing data processing for superimposing graphic data and displaying the ship position in combination, and a data processing unit 4
Input setting unit 6 for setting the processing conditions of the data processing unit 4 and the data processing unit 4
It has a configuration including a display unit 8 for displaying the output of the above, and an electronic chart data file 7 for storing electronic chart data.

Next, the operation of this embodiment will be described.

In the weather facsimile receiver 2, a plurality of types of weather maps such as a ground weather map, a cloud photograph, a high-level weather map, a sea condition map, etc. designated by the olepeter are input.

The input weather map is output as weather map facsimile data and supplied to the facsimile data input unit 3.

The facsimile data input unit 3 converts the inputted weather map facsimile data of the light and shade image data into graphic data and holds it as the latest weather map graphic data for each weather map type.

The compound navigation system 5 includes a Loran C receiver 9 and G.
Calculate the optimum ship position based on the data input from each navigation instrument such as PS receiver 10, NNSS receiver 11, gyro compass 12, and Doppler log 13, and add the reception status of each navigation instrument, and obtain the latest ship position data. The data is output to the data processing unit 4 at regular intervals.

The data processing unit 4 collects the data of the corresponding area from the electronic chart data file 7 based on the ship position data input at regular intervals and the display range and scale specified by the operator in the input setting unit 6. Extract and edit as electronic chart data for display. In addition, the data processing unit 4
Inputs the corresponding weather chart graphic data from the facsimile data input section 3 to at least one desired weather chart to be displayed, which is designated by the operator in the input setting section 6, and performs position matching processing with the display electronic nautical chart data. The weather chart graphic data subjected to the position matching process with the applied electronic chart data for display is output to the display unit 8, and the electronic chart and the weather chart including the ship position data are superimposed and displayed.

[0017]

As described above, according to the present invention, the electronic nautical chart and the weather chart are automatically displayed in a superimposed manner, which makes it possible to remarkably easily grasp the surrounding weather and sea condition with respect to the current ship position. effective. In addition, there is an effect that it becomes extremely easy for an operator to formulate a route plan and make a vessel maneuvering decision in consideration of weather and sea conditions.
