Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a rescue device that stops a ship when a passenger on the ship falls into or into the water.

(Prior Art and its Problems) Conventionally, rescue devices have been proposed that detect when a person on board a ship falls into the sea and automatically perform rescue measures. For example, as shown in Japanese Unexamined Patent Publication No. 60-103736, when a passenger carrying a handset, which is a transmitter, falls into the sea, the radio waves from the handset are interrupted and the receiver installed on the ship As the receiving input of the aircraft decreases, this is detected and the ship's engine is stopped, and a transceiver is used to transmit a distress signal to notify of the occurrence of an emergency situation.

However, with conventional rescue devices, if the power switch of the handset is accidentally turned off, or depending on the position or posture of the person on board carrying the handset, the reception input of the receiver may disappear or decrease. but,
In such cases, the ship's engine may be stopped unnecessarily. However, if the engine stops when a ship enters or leaves a port, especially when berthed or in rough weather,
This creates an extremely dangerous situation, as there is a risk of collision with the quay or other ships, or capsizing due to side waves.

(Technical means to solve the problem) The present invention was developed in consideration of the above-mentioned problem.If the ship's propulsion is lost due to the engine stopping, such as when entering or leaving a port or during stormy weather, it will be in a dangerous situation. The purpose of the present invention is to provide a rescue device that can prevent the engine from stopping regardless of the reception state, and the technical means thereof is to connect a handset 1, which is a portable transmitter, and a ship's A receiving section 3 installed to receive radio waves from the handset 1, and a stop output for stopping the sounding section 6 such as a speaker and the propulsion of the ship when the output of the receiving section 3 falls below a certain level. 8 and a control section 4 that outputs an activation signal to each of the radio control section 11 of the transmitter, the control section 4 has an output level that corresponds to the output level of the reception section 3. Regardless, a changeover switch 10 is provided for not outputting the stop output due to the actuation signal to the stop output section 8 among the outputs due to the actuation signal.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In Fig. 1, the handset 1, which is a transmitter, is designed to intermittently emit a carrier wave of, for example, about 130 MHz at a certain period, and the radio waves from the handset 1 are received by the receiver 3 and detected. The unit 4 is configured to output a detection signal S2 when the received signal S1 falls below a certain level. Timer section 5
is activated by the detection signal S2 from the detection unit 4, and outputs the activation signal S after a preset time.
3, S4, and S5 are output sequentially. The sound generating section 6 outputs a rescue message (for example, SOS and ship name), alarm sound, etc. stored in a memory in advance to the speaker 7 in response to the activation signal S3.
Amplify the sound from The engine stop output unit 8 operates a solenoid 9 that operates a manual lever 9a provided on the ship via a wire 9b or a rod in response to the activation signal S4, and Therefore, the engine is forcibly stopped (see Figure 3). As will be described in detail later, the engine stop output unit 8 is provided with a changeover switch 10 for not operating the solenoid 9 even when the activation signal S4 is input. 10
is attached to the panel surface of the main unit 2 at a position that is easy to operate. The radio control section 11 generates a message similar to that of the sounding section 6 described above and activates the transmitter 12 in response to the activation signal S5, and transmits a distress signal modulated by the message. The timing of these activation signals S3, S4, and S5 is, for example, S3 is 2 to 4 seconds after S2, S4 is 0 to 10 seconds after S3, and S5 is 0 to 10 seconds after S3.
It is preset to an appropriate value, such as 1 to 5 minutes after the start of the test.

FIG. 2 shows a specific example of the engine stop output section 8. In this figure, under normal conditions, the negative logic operating signal S4 is passed through the inverter 13 to the transistor TR.
1, thereby turning on transistor TR2.
is also turned on and solenoid 9 is activated. However, by switching the changeover switch 10 and grounding the base of the transistor TR1, the transistor TR1 is turned off regardless of the state of the activation signal S4.
Solenoid 9 remains inactive. As the changeover switch 10, for example, a two-position stable snap switch equipped with a locking mechanism is used, and the switch is designed to operate reliably without being changed unexpectedly, and to make it easy to operate and check the switching status. be. Changeover switch 10
As a result, the operation of the engine stop output section 8 is forcibly stopped, so the operation is more reliable and safer than, for example, a software method in which the operation signal S4 is not outputted by a program.

According to this rescue device, under normal use,
When a passenger carrying handset 1 falls into the sea, the input to receiving unit 1 is interrupted or reduced, so that received signal S1 falls below a certain level and detection signal S2 is output. This activates the timer unit 5, and after a certain period of time a distress message or alarm sound is emitted from the speaker 7. Then, after a certain period of time, the engine stops and the ship stops, and after a certain period of time, a distress signal is sent from the transmitter 12. will be sent. By keeping the changeover switch 10 on when entering or leaving a port or in rough weather, the output from the engine stop output section 8 is always off, so that even if the detection signal S2 is output due to a malfunction, the engine will not stop. Therefore, the danger of engine stoppage can be eliminated.

In the embodiment described above, the changeover switch 10 may be connected in series with the solenoid 9 to cut off the power supply to the solenoid 9. Furthermore, in the above embodiment, the engine stop output unit 8 is actuated by the actuation signal S4, and the engine is stopped by the solenoid 9. However, for example, the solenoid 9 is used to disengage a manual clutch. The rotation of the screw may be stopped while the engine continues to rotate, or the solenoid 9 may be replaced by a motor, or an appropriate relay may be used to output a signal to electrically operate the electromagnetic clutch. You can also cut it on target. Further, when the detection section 4 outputs the detection signal S2 while the ship is stopped, only the sound generation section 6 may be activated. The detection section 4, timer section 5, sound generation section 6, and wireless control section 11 can be implemented or controlled using an appropriately programmed microcomputer.

(Effects of the invention) According to the invention, a changeover switch is provided to prevent the stop output from being output regardless of the output level of the receiving section, so when entering or leaving a port, If the ship's propulsion force is lost due to the engine stopping, such as during stormy weather or when the ship's propulsion is in a dangerous situation, you can set this switch to prevent the ship from accidentally being propelled due to a malfunction. without losing power,
It's safe. Therefore, the rescue device of the present invention is
This not only protects the safety of passengers during normal navigation, but also prevents dangerous situations such as unexpected engine stoppages when entering or leaving port or during rough weather. Moreover, even if the stop output that stops the ship's propulsion is not output by changing the changeover switch, as described above, the operation signal from the sounding part such as a speaker or the wireless control part of the transmitter will not be output. Since it is designed to be output, it is possible to continuously notify the occurrence of an emergency situation using a speaker or a transmitter, and it is possible to protect the safety of passengers as much as possible.
