Description

[Brief explanation of the drawing]

FIG. 1 is a block diagram of an embodiment of this invention. Second
The figure is a partially detailed view of FIG. FIG. 3 is a diagram showing the relative relationship between the boat and the net. FIG. 4 is an explanatory diagram used when calculating the distance of the net position to the own ship. FIG. 5 is an explanatory diagram for explaining the relative relationship between a ship and a detector that detects the surrounding situation of the net. FIG. 6 is a block diagram of the detector.・

Claims (1)

[Claims for Utility Model Registration] Wave transmission and reception in which ultrasonic pulses are transmitted in a wide range of directions around the own ship and the reflected waves returning from each direction are received separately by receivers having directional directions in each direction. a time-series circuit that time-series the reflected waves in each direction received by the wave transmitting/receiving device and transmits the time-series signals; a coordinate converter for converting to a position; a first storage circuit having memory addresses of m rows and n columns and storing the selection signal of the time series circuit; and a coordinate converter for converting the time series signal sent from the time series circuit to the coordinate The first write circuit writes to the memory address of the first memory circuit designated by the converter, and the position of one ship is calculated based on the information sent from the navigation device that measures the navigational positions of the four ships. a controller that calculates a net position based on information sent from a net position measuring device that transmits a position signal and measures the position of the net, and a heading detector that detects the heading direction of the ship, and transmits a net position signal; a second memory having storage addresses in columns and n columns and storing device signals and network position signals constituted by the control unit; and a signal sent from the controller to the second memory. a second writing circuit for writing; a detector installed at an appropriate location on a net towed by a ship to detect the surroundings and transmit the detected information to the ship; and a receiver installed on the ship to receive the detected information. a receiver that amplifies the output signal of the receiver; a third storage circuit that has memory addresses in m rows and i columns and stores the output signal of the receiver; and an output signal of the receiver. a third write circuit for writing data into the third memory circuit; a display configured of m rows and (n+i) columns of pixels and displaying data stored in the first, second, and third memory circuits; a first reading circuit that reads data stored in the first storage circuit and displays the read data in a pixel area of m rows and n columns of the display device; a second readout circuit that displays the read data in the m-row n-column pixel area of the display; and a second readout circuit that reads the memory data of the third storage circuit and displays the readout data in the first pixel area of the display. and a third readout circuit that displays in a pixel area of m rows and i columns different from the display area displayed by the second readout circuit, and the first and second readout circuits synchronize with the display operation of the display device. and a switching circuit for switching the readout operation of the third readout circuit.
