Description of the Related Art In a ship such as a fishing boat operating a sea, a river, a lake, or the like, which is boarded by a single person, if the operator who operates the ship is normal, the operator operates according to the intention of the operator. It is possible, but if for some reason the operator fails and falls offboard,
The ship sails unmanned while leaving the operator offboard,
The operator will be left overboard. In addition, even if the operator does not fall offboard, there is a case where an emergency occurs and the operation of the ship needs to be stopped when working at a position away from the operating device.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has been made in consideration of the above circumstances. When an operator is left outside a ship or in an emergency, the operation of the ship is stopped, and the It is an object of the present invention to provide a ship operation control device which can surely stop the ship in case of leaving or an emergency and can cope with the emergency.

[0004]

A ship operation control device according to the present invention includes a transmitting device for transmitting a unique signal carried by an operator, and a unique signal mounted on a ship carried by the operator to receive the unique signal. The fixed receiving device confirms the reception of the transmission signal, continuously operates the operation device of the ship, and detects the decrease in the reception sensitivity of the transmission signal, thereby operating the operation of the engine of the ship. Stop so that this vessel is stopped. Here, for example, from the transmitting device transmits a ship-specific identification code signal at a specified cycle, the receiving device periodically recognizes the unique identification code, the operation of the ship operating device is continued, The operation of the engine operating the ship is controlled to be stopped based on the detection of the decrease in the receiving sensitivity due to the lack of the periodic recognition of the identification code. The transmitting device is provided with an emergency operation button, and a stop command signal is transmitted in accordance with the operation of the emergency operation button.

[0005] In the ship operation control device configured as described above, the transmitting device is always carried by the operator. Therefore, if the operator falls offboard, an accident occurs. The carried transmitting device also falls into the water, submerges in the water, and the receiving level of the receiving device mounted on the ship decreases. For example, if the transmitting device transmits the ship-specific identification code at the specified cycle,
A state occurs in which the periodic identification code received by the receiving device is missing. For example, when the missing device is detected twice, the abnormality of the operator is recognized, and the operation of the engine of the ship is reduced. Stop the operation of this ship. Therefore, it is possible to cope with the emergency evacuation of the fallen operator without operating the operator who has fallen outside the ship while leaving it outside the ship.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below based on an embodiment. As shown in FIG.
For example, in many cases, one operator 20 is on a boat 10 such as a small fishing boat. In such a case, if for some reason the operator 20 falls offboard as shown in FIG. 8B, the vessel continues to operate and leaves the operator who has fallen off. . In order to cope with such a case, a fixed receiving device 11 that issues a command to the operating device of the boat 10 is provided for the operating device of the boat 10, and at the same time, the operator 20 always carries the transmitter 21.

The transmitter 21 carried by the operator 20 is provided with an emergency button for coping with an emergency. For example, as shown in FIG. When an emergency occurs when the operator 20 is located away from the cockpit, which is a control device of the boat 10, the operator 20 operates an emergency button provided on the transmitter 21 to be carried. . By the operation of the emergency button, the transmitter 21 transmits an emergency signal, and the receiver 11 receives the emergency signal and
Issue a stop command to 10 engines. And this ship 10
Will be shut down immediately to ensure safety.

FIGS. 1A and 1B show the configurations of a transmitter 21 and a fixed receiver 11, respectively.
The transmitter 21 shown in the figure includes an ID code generator 31 that generates an identification code unique to the ship 20. The identification code generated by the ID code generation unit 31 is supplied to an encoder 32, and the output from the encoder 32 is supplied to a high-frequency transmission unit 33 including a modulation unit, and transmits a signal obtained by modulating the identification code.

A timing signal from a transmission control timer 34 is supplied to the high-frequency transmitting unit 33. For example, the transmitting unit 33 is controlled so that a modulation signal of an identification code is generated at a specified cycle. . For example, a signal generated intermittently every 5 seconds is transmitted.

The transmitter 21 is provided with an emergency button 35, and a signal from the emergency button 35 is transmitted to the
Data generator that generates safety data or emergency data
Supplied to 36. In the non-emergency state where the emergency button 35 is not operated, the transmission control timer 34 generates a normal timing signal at 5-second intervals, and the high-frequency transmission unit 33
, A signal of a predetermined identification code is transmitted intermittently at intervals of 5 seconds.

The data generator 36 outputs safety data when the emergency button 35 is not operated, and the encoder 32 outputs an encode signal corresponding to a normal state. When the emergency button 35 is operated, the emergency data is
The encode signal is supplied to the emergency signal generator 32 to report an emergency, and an emergency signal is generated from the high-frequency transmitter 33.

(B) The fixed receiver 11 shown in FIG.
And an antenna 41 for receiving a signal from the antenna. The received signal is amplified by an RF amplifier 42 and demodulated by a demodulator 43. The demodulated signal is amplified by the AF amplifying unit 44, shaped by the waveform shaping unit 45, and then input to the decoder 46 for decoding.

The decoder 46 has an ID code generator.
The identification (ID) code from 47 is input and compared with the encoded received signal to recognize that the identification code of the ship 10 has been received. The fact that the recognition code is received at a predetermined cycle indicates that the safety signal detection unit 48
Is confirmed, the safe operation is confirmed, and a control command is given to the relay control output unit 49 based on the safety confirmation, and the engine is continuously operated. If the safety is not confirmed by the safety signal detector 48, the state is confirmed by the abandon detector 50 and the relay control output
A command is given to 49 to perform stop control of the engine, and the abandonment detection unit 50 outputs an distress signal and transmits an distress signal to other ships.

When the decoder 46 cannot receive the predetermined periodic signal continuously,
Is operated and emergency data is oscillated from the transmitter 11, the decoder 46 generates an emergency signal. Then, this emergency signal outputs an emergency signal to the relay control output unit 49.

In a normal state in which a safety signal is input, an output for normally operating the engine of the ship 20 is obtained from the relay control output unit 49. When an emergency signal is input, a command for controlling the stop of the engine is output. I do. Also, an emergency signal (SOS) corresponding to the engine stop output is appropriately provided.
Is generated.

The demodulated signal from the demodulation unit 43 is further supplied to an interference wave detection unit 51. In the case of receiving a signal similar to the signal transmitted from the transmitter 21 of the ship 10 or a disturbance wave, the disturbance detection unit 51 outputs the detection signal to the relay control output unit 49 and outputs the detection signal to the alarm 52. , Generate an alarm signal.

In a state where jamming radio waves are present, safety may not be confirmed by the safety signal detecting section 48 in a normal operation state in which the ship 10 and the operator 20 have no abnormality. In other words, even if the radio wave is normally transmitted from the transmitter 21 carried by the operator 20n, the radio wave cannot be recognized by the receiver 11 decoder 46. Regardless, the engine stop control is performed.

Therefore, when an interference wave is detected by the interference wave detection section 51, the detection signal is transmitted to the relay control output section.
The control signal is supplied to the safety signal detector 49 so that the engine stop control is not performed even when the safety detection from the safety signal detector 48 is not confirmed.

In the apparatus configured as described above, care is taken to transmit a weak radio wave enough to cover a short distance so as not to interfere with a nearby consignment ship or the like. And
A signal obtained by modulating the ID code unique to the ship is intermittently transmitted from the transmitter 21 at intervals of, for example, 5 seconds. The receiving device 11 associated with the steering device monitors whether or not the signal at the interval of 5 seconds is normally received.

A transmitter for transmitting such an ID code signal
Reference numeral 21 denotes a small, lightweight, portable and waterproof type, which is carried by the operator carrying the transmitter 21.
If, for example, 20 falls off the ship, the transmitter 21 is immersed in the water and the transmission radio wave is weakened. In addition, the operator 20 who has fallen due to the navigation of only the ship is abandoned, and the transmitter 21
The distance between the receiver and the receiver 11 is increased, and the radio wave received by the receiver 11 is weakened.

When the intensity of the radio wave received by the receiver 11 decreases in this way, it becomes difficult to stably receive the radio wave from the transmitter 21 which is intermittently transmitted, and all the intermittent transmission signals are transmitted. The reception signal cannot be received, and the reception signal is lost. For example, if there is a continuous loss of the periodic signal twice, this is detected by the decoder 46, the detection signal in the safety signal detector 48 is lost, and an emergency signal is output from the decoder 46. Is input to the relay control output unit 49 to control the stop of the engine. Therefore, the ship is stopped without leaving the operator 20 who has fallen excessively, and the safety of the operator 20 is maintained.

In the case where the operator 20 is away from the control device of the ship 10 and an emergency condition occurs on the ship, the operator 20 operates the emergency button 35 of the transmitter 21 to be carried.
Operate. Emergency data is generated from the data generator 36 in accordance with the operation of the emergency button 35, and the emergency data is supplied to the encoder 32, and outputs an emergency signal for commanding engine stop. Received at 11. Then, the reception of the emergency signal is detected by the decoder 46, an emergency signal is output, and the engine is emergency stopped.

[0023]

As described above, according to the ship operation control device of the present invention, especially when the operation is controlled by one person, the operation of the ship is stopped and controlled in the emergency state of the operator. Yes, for example, when the operator falls into the sea, the ship is automatically stopped, and the occurrence of the abandoned state is reliably prevented. In addition, when the operator is away from the control device and is operating automatically, for example, in the case of an emergency such as a net entangled in a fishing boat, the operator may operate the emergency button of the transmitter. As a result, the ship is brought to an emergency stop and safety is ensured.
