The initial disaster prevention work when an abnormality in the ship is detected is mainly carried out by the crew designated in charge, and when the situation becomes large, it is customary for the entire crew to deal with this. Is. However, in recent years, the number of ships operating with a small number of people has increased with the progress of ship technology. In such vessels, regardless of the severity of the situation, everyone will have to deal with this immediately.

That is, all of the on-duty person, the on-duty person, and the off-duty person are driven out regardless of the size of the abnormality.
As a result, the duties of the person concerned may be neglected, and crew members who are off duty and resting will also be mobilized, which will hinder the duty after the fact. Both can pose another danger.

According to the present invention, when the degree of abnormality in the ship is slight, only the watchman handles the abnormality, and when the abnormality is moderate, the one on duty on the bridge handles it. When it is not possible, the task is to propose a security device that enables all crew members, including off-duty personnel, to deal with it.

[0014]

[Operation] The operation of the present invention will be described with reference to FIG. The portable unit is small and light, and is always carried by the watchman. On the other hand, the main unit is placed on the bridge where the person on duty is on duty. However, the third alarm circuit AL3 is provided in a place reserved by the person on duty, and the fourth alarm circuit AL4
Will be installed in a recognizable location on all ships.

The predetermined count values set by the first, second, third and fourth preset circuits PS1, PS2, PS3 and PS4 are the first, second, third and fourth counting circuits CN1, C
Times T1, T2, T3, T4 until the count values of N2, CN3, CN4 reach their respective predetermined count values are set to become longer in this order.

After a lapse of time T1, for example, 13 minutes, from the resetting of the first counting circuit, the first alarm circuit turns on the light,
An alarm is generated by sound.

When the person on duty is working normally, the reset button RB is pushed. As a result, the first counting circuit CN1
Are reset and the first alarm circuit is stopped.

When the reset button RB is pressed, a transmission signal is generated by the transmission circuit T, and electromagnetic waves are radiated from the first antenna AN1.

This electromagnetic wave is received by the second antenna AN2 of the main unit, and is amplified by the receiving circuit R. Based on the output of the receiving circuit R, in the decoding circuit DC,
It is determined whether the reset button RB has been pressed.

The second clock CL2 on the main body side is counted by the second counting circuit CN2, and when it reaches the count value set by the second preset circuit, the second alarm circuit AL2 in the bridge is reached.
Generates an alarm by light, sound, etc.

The time T set by the second preset circuit
The second counting circuit CN2 is reset by the output signal of the decoding circuit DC when the reset button RB of the portable unit was previously pressed for 2, for example, 15 minutes. As a result, the second counting circuit CN2 has the second preset circuit PS.
Since the count value set in 2 is not reached,
Alarm circuit does not work.

To summarize the operation up to this point, the watchman receives an alarm from the alarm circuit AL1 of the portable unit after a lapse of time T1 from the resetting of the first counting circuit. If you press the reset button RB of the portable unit quickly,
The second alarm circuit AL2 of the main unit does not operate.
However, the second alarm circuit in the bridge issues an alarm when the time T2 elapses after the second counter circuit CN2 is reset without pressing it promptly.

The operation of the second alarm circuit means that the person on duty falls asleep, suffers an illness, dies, or any other emergency.

When the person on duty is asleep, he is awakened by the alarm of the second alarm circuit AL2 in the bridge.

When the watchman was dozing, the vessel was not being monitored, so the vessel must check the situation of the vessel at the time when it is blank.

Therefore, at the same time when the second alarm circuit AL2 operates, the check sequence of the check sequence device CS starts up.

The check sequence device CS is provided with signal lines L from various parts inside the ship to determine the external environment, the position of the ship,
Information is gathered on stuttering, water depth, approaching dangerous materials, heading, oil leaks, high bilges, fires, etc.

The check sequence is a sequence for confirming whether all or some of them are safe.

The confirmation work is carried out by a CRT using a computer.
It can be done interactively above.

When the check sequence is completed successfully,
A reset signal is generated, the second counting circuit CN2 is reset, and the operation of the second alarm circuit AL2 also stops. It should be noted that the confirmation button AB is displayed before the check sequence ends.
The operation of the alarm circuit AL2 can be stopped by pressing.

In this way, when the person on duty is asleep, the safety can be confirmed by the check sequence by the awakened person on duty. Therefore, it is possible to end the situation without seeking assistance from other crew members.

In a situation where the watchman cannot press the reset button RB due to illness, death, fire, etc., and the check sequence cannot be operated, the captain or a person on duty assists the watchman. Must.

Therefore, when the count value of the second counting circuit CN2 reaches the count value set by the third preset circuit PS3, the third alarm circuit AL3 operates.

The time T3 required to reach this set value is
The installation value of the third preset circuit PS3 is chosen such that it takes longer than the time required to complete the check sequence. Therefore, the operation of the third alarm circuit AL3 means that a serious abnormality such as death of the watchman or a fire has occurred.

The third alarm circuit AL3 is provided in the captain's room or in a place reserved by the person on duty. When the third alarm circuit AL3 operates, the captain or the person on duty will
Gather in Funabashi and work together to deal with emergencies.

The rescuer who came to the bridge confirms the safety of the ship by using the check sequence, and when this is completed, a reset signal is sent from the check sequence device CS to the second counting circuit CN2, and the second counting is performed. The circuit CN2 is reset and the second and third alarm circuits are stopped.

It is also possible to change the contents of the check sequence after the third alarm circuit AL3 is activated and that before the check sequence.

When a fire or the like occurs, it is necessary to request the rescue of another person as soon as possible. In preparation for such a situation, the portable unit is provided with a rescue request button HB.

When the rescue request button HB is pressed, the transmission circuit T generates a signal corresponding to it, whereby the first antenna AN1 radiates an electromagnetic wave corresponding to it.

This electromagnetic wave has a second antenna AN on the main body side.
2 is received, is amplified by the receiving circuit R, and is decoded by the decoding circuit D
It is determined by C that the rescue request button has been pressed.

When the decoding circuit DC makes the above determination, the third alarm circuit AL3 is immediately activated. That is, an alarm circuit provided in a place reserved by the captain or a person on duty operates. According to this, they rush to the bridge where the watchman is waiting.

Even if the captain or the person on duty goes to the bridge,
There are times when emergency situations cannot be dealt with. In such cases, the cooperation of all crew members is necessary.

The predetermined count value set by the fourth preset circuit PS4 has a check sequence after the operation of the third alarm circuit AL3 until the count value of the second count circuit CN2 reaches that value. It is set longer than the time normally required to finish.

When the check sequence cannot be completed and the second counting circuit reaches the count value set by the fourth preset circuit PS4, the fourth alarm circuit AL4 operates.

The fourth alarm circuit is installed in a place where all crew members can recognize it. Therefore, when this alarm is activated, all crew members will work together to deal with an emergency.
