Various data from the satellite receiver 1 and the ship / land weather observation equipment 2 are temporarily stored in the corresponding data frames 31. The database 32 stores various fishery information continuously acquired from the past.
The PC 33 reads the data of the data frame 31 and the data of the database 32 and creates various GIS screens of a predetermined sea area based on the distribution of water temperature, water color, sea level, weather, current fishing ground, predicted fishing ground, and ship measured water temperature distribution as distribution contents. The distribution server 34 processes the data according to the transmission protocol and sends the data to the communication infrastructure 4.
[0008]
The communication infrastructure 4 includes a communication terminal 41. In this embodiment, satellite packet communication via N-Star is used, but use via the Internet or the like is also possible.
[0009]
The multi-source fishery information receiving and displaying device 5 is a device mounted on a fishing boat desiring the distribution of the data, and includes the following devices.
51 is a communication terminal, 52 is a GPS receiver, 53 is a data processor, and 54 is a display.
When the data processor 53 is activated, the communication terminal 51 automatically accesses the distribution server 34 and is set to a data acquisition state.
The GPS receiver 52 sends data such as its position, ship speed, course, etc. to the data processor 53.
The data processor 53 reads desired GIS screen data and GPS data, processes and processes them, and renders a screen as shown in the following figure on the display 54.
[0010]
FIG. 2 is a diagram showing an example of a case where the own ship position obtained by the GPS receiver 52 is displayed on a chart drawn on a display 54 by switching between a GPS screen for displaying the own ship position and a plurality of GIS screens. Screen 1 is a GPS screen, Screen 2 is a 4-split GIS screen that displays the distribution of water temperature, light blue, sea level, and air pressure, and Screen 3 is a 4-split GIS screen that displays ship water temperature, waves, typhoons, and fishing ground information. It is. These three screens are switched by operating buttons provided on the data processor 53.
[0011]
FIG. 3 shows an example in which four types of GIS screens are divided into four screens and one of the screens is switched to a full screen. Screen 4 is a divided display screen of four GIS screens, and screen 5 is the four kinds of GIS screens. This is a full screen display in which one screen is selected. Selection of these screens is performed by operation buttons provided on the data processor 53.
[0012]
