Description

[Detailed description of the invention] This invention relates to a cell call buoy.

A buoy is equipped with a wireless transmitter/receiver, a command signal format specific to the buoy is determined, and the command signal in the determined format is transmitted from another radio station to control the wireless transmitter/receiver of the buoy and identify its own station. A code is transmitted, this transmitted power tlL' is measured with a radio direction finder, and homing is performed to that pin.
g) A cell call buoy is used to Therefore, the radio waves emitted from the cell call buoy are determined to be in a radio wave format suitable for wireless direction measurement, and have not been used in the past for transmitting information other than the own station's identification code.

On the other hand, in order for fishing vessels to improve their operational efficiency,
It is desirable to have detailed information on the weather, sea conditions, etc. of the sea area related to fishing operations, but the amount of information released by meteorological observatories, fisheries experimental stations, etc. regarding the desired sea area is too small, and the amount of information regarding the desired sea area is too small. The disadvantage was that the information that could be observed was limited to the vicinity of the location of the fishing boat.

This invention was made in order to eliminate the above-mentioned drawbacks.In this invention, the cell call buoys, which are installed in the operational sea area and have a large number of stones, are used.Seventh, the format of the radio waves emitted from the call buoys is the same as that of the cell call buoys. While maintaining the format prescribed by radio wave related regulations, the system transmits information such as weather and sea conditions at the location where the cell call buoy is installed, and does not require any additional equipment to receive this information onboard the fishing boat. By simply adding the desired sensor (Hata・ni@r) to the cell call buoy, six
The purpose is to provide a system that can provide fishing boats with information about their prey.

Hereinafter, the present invention will be described in detail with reference to the drawings.

) is the same as that of a conventional cell call buoy, and its operation is well known, but the operation will be simply explained below.

Convert to CD (binary coded 1O base) digital code of approximately 2 digits. The code conversion circuit (20) converts the ADC (19) to 0
Convert BCD to Morse code for each decimal digit and latch (20 companies store this Morse code for one time.

The input point from the code conversion circuit (2) to the latch (21) is controlled by the signal on the signal line (26). In this way, when the Morse code representing the analog voltage of any one senna in tenths is set in the latch Φ), the contents of this latch (21) are read out at a predetermined speed and the wireless transmitter (7) is activated. Modulate and send. The speed of the Morse code generated by reading the contents of this latch (20) is set to be the same as the speed of the Morse code generated by the identification code generator (6), and the radio wave format emitted by the wireless transmitter (7) is also set in the same manner. If this is done, the output information of the sensor can be transmitted using the radio wave format emitted by the cell call buoy.When the output information of one sensor is finished being transmitted, the selector (18) is used to select the next sensor in sequence. The output information can be transmitted.O Onboard a fishing boat, you can obtain information such as weather and sea conditions at the location where the cell call buoy is installed by simply receiving the radio waves emitted from the cell call buoy and listening to the Morse code. □"Which cell call buoy the information comes from can be determined by the order in which the cell call buoy station identification code is heard.

The information from Senna is sent out sequentially in the same manner as described above. However, while the timing control circuit (SO) activated by the signal on the signal line (22) is in operation, even if a periodic signal is output on the signal line (56), the timing control circuit (SO) will not operate until the control circuit (50) completes its operation. delays activation of the control circuit (51). This delay control is performed by a signal on the signal line (to).
