Description

[Detailed Description of the Invention] The present invention provides a plurality of position information obtained from own ship and other ships,
The present invention relates to a device that displays a plurality of wakes in several colors classified by depth layer and temperature layer based on water depth and temperature information.

Conventionally, a track display device that displays own ship's position on a CRT screen in the full Mercator projection has been able to display water depth distribution and water temperature distribution by displaying the own ship's track in several colors specified for each depth layer and temperature layer. There is a way to obtain this information, but you can only obtain depth and temperature values along your own ship's track, so in order to obtain a depth and temperature distribution map over a certain range, you must repeatedly navigate in meandering directions, or
Also, due to reports from other ships accompanying the ship.

This required manual input into the track display device, which was extremely inefficient. 'Also, there is a method such as radar that captures moving targets and displays them as the wake of other ships, but this can only display the wake and cannot superimpose water depth information. Ta.

In the present invention, the position information and water depth temperature information collected by one or more other ships accompanying the own ship are received via wireless communication, and the number of wakes of these other ships is determined by temperature stratum at all depths. Depending on the color of the seeds.

The above requirements are satisfied by providing a second track display function that displays the own ship's track online and in real time on a color display.

A detailed explanation will be given below according to the drawings.

Figure 1 is a configuration diagram of the receiving side showing the principle of this utterance.
is a track processing unit that includes an arithmetic unit, memory, and interface f, and is mainly composed of a microprocessor, and is capable of processing position information from various position measuring devices (hereinafter simply referred to as navigation devices) such as satellite navigation devices and Loran navigation devices, as well as water depth gauges. Receives water depth and water temperature values from the water thermometer. Furthermore, by comparing these water depth values and water temperature values with each depth layer and temperature layer specified in advance in several colors.

The depth layer and temperature layer to which it belongs are determined, and the sent position information is converted into CRT display information of the color of the depth layer and temperature layer to which it belongs. (The color boxes or values of the depth layer and temperature layer can be specified later and displayed again.) This CRT display information is sent to the color display 2.

Displayed as your ship's track, color-coded by water depth or water temperature.

The conventional track display device has been described above, and the main parts of the present invention will be described below. 3 is a receiving section that receives all the signals sent from one or more other ships through the wireless line; 4 is a receiving section 3;
5 is a reception signal memory that sequentially stores information from the reception signal processing unit 4; 6 is an arithmetic control unit consisting of a microprocessor, RAM, ROM, etc.; 7 is a wake A color graph ink memory for temporarily storing color CRT information such as characters and symbols, and 8 is a video signal generating section.

Next, we will discuss the operation. The scale and latitude of the sea area to be displayed by the unselected track processor 1.

Initial values for drawing longitude lines, etc. are set, and based on this information, the scale value and latitude are displayed on the color display 2.

Lines of longitude are drawn. In addition, it receives all location information from the navigation device and depth gauge water temperature values from the water depth gauge.

After comparison with the depth layer temperature layer, which can be added in advance or later, the position information is converted into CRT information and sent to the color display 2, where the own ship's track is displayed. - In the fc, the position information and water depth information of other ships sent from multiple other ships through wireless lines are received continuously or at regular intervals by the receiving unit 3, and are tuned and sent to the received signal processing unit 4. will be sent. When receiving all signals from multiple other ships, receive them by scanning all the signals from each other ship according to rules agreed upon in advance between the other ships and your own ship.

The position information and water depth temperature information of other ships sent from the receiving section 3 are converted into digital values by the reception signal processing section 4, and then further converted into digital values according to rules established for each other ship (for example, a code is determined for each ship). Then, use that code to identify multiple other ships.

) is classified into position information and water depth and temperature information for each other ship, and stored in the received signal memory 5 at an appropriate timing.

At the same time, the position information and water depth and temperature information are sequentially sent to the arithmetic and control unit 6 for each ship along with a symbol identifying which ship the information is from. The arithmetic control unit 6 uses the current scale value from the track processor 1, the own ship's position information (latitude and longitude, position on the CRT screen), and other ship position information sent from the reception signal processing unit 4. , the relative distance between the own ship and the other ship is calculated, and the position information of the target other ship is converted to the CRT screen position on the full color display 2. Furthermore, the color of each depth layer temperature layer from the track processor 1 for the water depth temperature 1H report sent from the received signal processing unit 4 together with the position information.

Based on the value information, the depth layer and temperature layer determined in several colors are compared to determine the depth layer and temperature layer to which it belongs, and the display color of the target ship's track is determined.

′-! The arithmetic and control unit 6 has a part of internal RAM provided with an area for temporarily storing the latest sent position information and water depth and temperature information for each other ship.

It has a function of constantly updating the corresponding ship's position, water depth, and water temperature information using information from the received signal processing section 4.
A track is created by connecting the position of the other ship that has just been sent and the past position of the target other ship stored in the storage area with a straight line of a color determined by comparing the size with the depth layer and temperature layer. Control what is displayed. Under these controls, the information of the calculation side (material) section 6 is stored in the color graphic memory 7 corresponding to the CRT pixels. In addition, if it becomes necessary to redisplay the entire CRT screen according to a command from the track processor 1 (for example, when the scale value is increased, or when each depth layer is
(If the color and value of the IM degree layer can be specified), the information of each other ship in the past is read out sequentially from the received signal memory 5, and the track of each ship is reproduced by performing the calculation control described above. do. Color graphic memo! J7U TV For V-scan color display, it consists of three screens worth of memory corresponding to the red, blue, and green colors of the electron gun, and stores data according to the color of the wake. Furthermore, the information from the color graphic memory 7 is sequentially read out by the video signal generator 8, and the color display 2
A video signal k synchronized with the CRT is generated and inputted to the color display 2 to be displayed in color by superimposing it with signals of the own ship's track, latitude lines, longitude lines, etc.
