Abstract

PURPOSE:To allow a fallen person to be returned easily to a boat by providing an engine stopping means to stop the engine of the fish boat automatically if a fall takes place. CONSTITUTION:A worker being the operator works with a slave set 1 on his body. If the worker falls into a sea in error, a radio wave from the slave set 1 is interrupted, a detection output from a reception circuit 2 of a master set 19 is lost, a timer means 4 is triggered and started. When the worker returns before the means 4 times up and resets a reset switch 18, the state is restored to the initial state. If the worker is delayed to return to the boat due to any cause and the means 4 times up, a rescue signal from a transceiver 7 is transmitted and also an engine stop signal output means 17 is operated to stop the engine.

Description

Detailed Description of the Invention The present invention provides a vehicle equipped with a wireless communication means such as a transceiver, and when working alone in a certain range, the worker leaves the vehicle for some reason and disables the transceiver. The present invention relates to a distress signal transmitting device having an engine stop device that automatically stops the engine and operates a transceiver to issue a distress signal when operation becomes impossible.

More specifically, motorized fishing vessels equipped with fishing transceivers operate while exchanging information via transceivers, and although these vessels may operate as an organized group, they usually do not Because they are privately run businesses whose income is determined by the amount of fish they catch, they often board their own fishing boats and do their own work.

Therefore, if you accidentally fall into the sea while working, you can return to the boat immediately if you are working with the engine stopped, but if you are working with the engine running, you may swim back to the fishing boat. Even if they try, depending on the speed of the fishing boat, they may not be able to swim, and there are even cases of people being left behind and dying from exhaustion.

When such a fall accident occurs, the present invention automatically stops the fishing boat's engine to make it easier to return to the boat, and also makes it possible to send a distress signal from the transceiver to request rescue from fellow boats. The object of the present invention is to provide a distress signal transmitting device having a novel engine stop device.

Furthermore, if the present invention returns to the ship within a short preset time, the engine can be reset before stopping the engine or issuing a distress signal, and if the invention returns to the ship while the distress signal is being sent, after returning to the ship. The object of the present invention is to provide a distress signal transmitting device that includes a novel engine stop device that can quickly stop transmitting a distress signal.

A basic first embodiment of the configuration of the present invention shown in FIGS. 1 and 2 will be described.

A handset 1 that is a transmitter that has an oscillator of a specific frequency and transmits weak radio waves of a specific format (for example, AI that is an unmodulated continuous wave, A3 that is modulated at an audible frequency, etc.);
a receiving circuit 2 equipped with an appropriate antenna for receiving radio waves of a specific frequency transmitted by the handset; a control output generating means 3 generating a pulse-like control output based on the output of the receiving circuit 2; and a control output generating means 3 for generating a pulse-like control output. A timer means 4 which is triggered and activated by the control output of the timer means 3; and a message generating means 5 which generates a distress signal message pre-recorded or the like based on the time-up signal of the timer means 4.
, a sounding means 6 which is activated by the control output of the control output generating means 3 to generate an alarm sound, and a transceiver 7 on the input side.
input side connection means 11 for connecting to the microphone 9 of the breathtalk microphone 8 and the breathtalk switch 10;
and microphone circuit 1 of 1 to transceiver 7 on the output side.
2 and an output side connection means 14 connected to the breathtalk switch circuit 13, and the timer means 4 closes the breathtalk switch circuit 13 of the transceiver 7 and generates the mesage in the microphone circuit 12 of the transceiver 7. transmission/reception switching means 15 for applying the output of means 5; engine stop signal output means 17 having an engine stop output terminal 16; timer means 4; message generation means 5; sound generation means 6; A reset switch 18 that resets the signal output means 17 and returns the device to its initial state.
and a base unit 19 having a base unit 19.

Since this example is configured as described above, the first
Microphone circuit 1 of transceiver 7 as shown in the figure.
2 and the breathtalk switch circuit 13 are connected to the output side connection means 14 of the transmission/reception switching means 15 using an appropriate cord, and the breathtalk microphone 8 of the transceiver 7 is connected to the input side connection means 11 for use. When used in this way, when the transmitting/receiving switching means 15 is not operating, the microphone 9 of the Breathtalk microphone 8 and the Prestoke isochi 10 are directly connected to the transceiver 7, so the transceiver 7 can be used normally. I can do it. - The worker, who is an operator, closes the switch of handset 1 (not shown) and wears handset 1, which is a transmitter, while working, but if the worker accidentally falls into the sea, The radio waves from the device 1 are interrupted, and the detection output from the receiving circuit 2 of the base device 19 disappears.

When this detection output becomes below a certain limit, the control output generation means 3 generates a control output (in the form of a pulse), triggers and starts the timer means 4, and activates the message generation means 5. A rescue message (for example, SOS...--1--...)
and the ship's name), and this message is applied to the sounding means 6 consisting of an amplifier and a speaker to make it sound.

If the operator returns to the ship before the timer means 4 times up, he will know that the device is operating by the sound emitted from the sounding means 6, and will reset it by operating the reset switch 18. For example, when the sound generation means 6 stops producing sound, it returns to its initial state and the transmission/reception switching means 15 does not operate, so no distress signal is issued, and the engine stop signal output means 17 also does not operate, so the engine does not stop.

If there is a delay in returning to the ship due to some reason, and the timer means 4 times out, the message generating means 5 is activated to reproduce the aforementioned distress message previously recorded in the message generating means 5 and simultaneously apply it to the transmission/reception switching means 15. ,
The transmission/reception switching means 15 operates to close the breath talk switch circuit 13 of the transceiver 7 and apply the output of the message generation means 5 to the microphone circuit 12 of the transceiver 7, so that the transceiver 7 enters the transmitting state. When the distress signal message applied to the microphone circuit 12 is transmitted from the transceiver half, the engine stop signal output means 17 also operates to close the engine stop output terminal 16. Therefore, a commercially available engine stop device is provided in advance, and a If the engine stop output terminal 16 is connected to the terminal, the engine will be stopped and it will be easier to swim back to the ship. Ru.

The above operation will be explained in more detail based on flowchart 1 shown in FIG.

In the figure, P1 to P1O indicate each step of the flowchart.

The receiving circuit is a superhetero gain (preferably a double superhetero gain depending on the frequency used) with an automatic gain control circuit, and the detection output or the DC output of the automatic gain control circuit is set to a certain limit value at Pl. When the following occurs, a pulse-like control output is generated.P2) The timer means 4 is triggered to start the timer means 4 (P3).

Next, at P4, it is checked whether the reset switch 18 is ON, and if it is not ON, the message generating means 5 immediately
and activates the sounding means 6 to emit an alarm sound. This alarm sound will continue for several seconds to several minutes, which is preset until the timer 1 timer 4 completes the timer operation. When it is determined that transmission has stopped, the reset switch 18 is operated to stop the operation of the sound generating means 6, and the device is inspected.

If such an operation is not performed while the timer means 4 is operating and the set time of the timer means 4 has elapsed and the time is amplified, check the reset switch 18 again (P8), switch the transmission/reception switching means 15 (P9), and turn off the transceiver. -7 is in the transmission state, the output of the message generating means 5 is applied to the microphone circuit 12 of the transceiver-7 to transmit a distress signal, and an engine stop signal is output (P], O) to start the engine as described above. Stop.

Even after the distress signal has been sent, if the operator returns to the ship, he or she can operate the reset switch 18 to reset and stop the distress signal.

As mentioned above, this distress signal message continues to be transmitted until the operator returns to the ship and operates the reset switch 18, so the consort ships can detect the content of the miscellaneous signal message and the direction finder. Search and rescue operations depend on the direction of the distress signal.

Furthermore, it is desirable that this distress signal be transmitted intermittently, for example, transmitted for several seconds and stopped for several tens of seconds, in order not to interfere with communication between consort ships.

Note that the sound generation means 6 may be a buzzer or a low-frequency blast (consisting of a chimney and a speaker).As the message generation means 5, a suitable recording device is used to pre-record the ship name, etc. If the sound is reproduced by the output of the output generating means 3 or the timer 4, the sound generating means 6 will only need to consist of an amplifier and a speaker.

The preferred embodiment shown in FIGS. 3 to 5 will be described in detail below.

Various circuits have been added to this example to make it operate more reliably and stably, and the basic operation is the same as that of the previous example, so it is different from that of the first example. The same parts are given the same reference numerals, but there are two timers, and the first engine stop timer, which amplifies the time in a relatively short period of time before sending out a distress signal, is used to stop the ship. The engine is stopped to make it easier to return to the ship, and a distress signal is sent after the time required for returning to the ship, which is set by the second timer 4, is elapsed, in an attempt to prevent the dispatch of distress signals. The steps for checking the reset switch are different from those in the first embodiment.

As shown in FIG. 5, the handset 1 oscillates with an oscillator OSS equipped with a crystal CR, drives a power amplifier PA through two stages of multiplier amplifiers MA1 and MA2,
By transmitting radio waves in the 0 MHz band, the frequency is stabilized, and the pulse generation circuit PO generates pulses with short duration and long pause time as shown in the figure, and the switching circuit SC is used to control the power amplifier P.
The power consumption is reduced by modulating A and transmitting a radio wave with a duration of 125 milliseconds and a rest time of 875 milliseconds, for example.

' Furthermore, the handset 1 is equipped with a secondary battery SB such as a nickel-cadmium battery, a charging terminal CRT, and a normally closed switch SSW. Although not shown, as is well known, a recess for accommodating the slave unit is provided in the casing of the base unit,
When the handset 1 is accommodated in this recess, the switch SSW opens and the charging terminal CHT is connected to the charging terminal CO for the handset of the main unit 19.
Connect it to T to charge it.

As shown in FIG. 3, the main device 19 is supplied with power from the power input terminal 51 via the power switch psw to the power supply circuit SC to obtain the required voltage output, and is also supplied with power to the child device charging terminal COT via the child device charging circuit CHC. are doing. This power supply episode F! 8
One circuit out of the voltage outputs of sc is connected to a power input terminal Sl, and is connected to an input of an engine rotation detection circuit ERD, which will be described later.

Furthermore, the main device 19 is provided with a test switch TSW for testing the state of the device as necessary, and a recording switch R3W for operating a recording circuit for recording a distress signal message.

Engine rotation detection circuit E that detects the presence or absence of engine rotation
As mentioned above, the RD input is connected to the power input terminal S■, so it contains a ripple voltage of about 5-0 millivolts while the engine is running, so this ripple voltage is extracted with a filter and amplified. The output and an engine stop timer EST are connected to a timer means 4 and a control circuit CC to be described later via an AND circuit AND.

Further, the engine stop signal output means (17) for stopping the engine includes an engine stop relay circuit RYC connected to the control circuit CC and its relay contact output ESO, and is connected to the engine stop output terminal (16).

In addition to the addition of these circuits, in order to effectively utilize the radio waves modulated by the pulses of the handset 1, the control output generating means 3 includes a pulse interval confirmation circuit PRC1 and a detection output confirmation circuit DRC1. Since the interference indicator lamp I L is installed, a separate control circuit C is installed to effectively process information from these many signal sources.
C is provided.

The input of the control circuit CC is connected to the detection output confirmation circuit DRC, the timer means 4, the test switch TSW, and the reset switch 18, respectively, and an AND circuit AND is connected to the output of the engine stop timer and the engine rotation detection circuit ERD. The transmitting/receiving switching means 15 is also connected. The output of the control circuit CC is connected to the detection output confirmation circuit DRC, the message generation means 5, and also to the transmission/reception switching means 15 to control the present apparatus.

As shown in the figure, the engine stop timer EST includes a rough resistance ESR for setting the engine stop time, and the timer means 4
A variable resistor STR for setting the time to start transmitting a distress signal is provided respectively. The former is lO ~ several 1 seconds 0 seconds is 1
Each time can be set in the range of ~ several minutes.

The operation of this embodiment will be explained based on the flowchart shown in FIG.

PL-P9 is a basic step in the flowchart, and steps that are substantially the same as those in the first embodiment shown in FIG. 2 are given the same reference numerals, but as described above, Although it is slightly different due to the addition of various additional circuits,
The reset switch 18 always has priority, and if the reset switch 18 is closed at any step, it returns to a younger state.

Each step surrounded by a chain line R in the drawing is for operating the recording circuit REM by the recording switch R3W. The recording circuit REV is a non-volatile semiconductor memory element such as a 2 kilobyte RAM backed by a battery.
It can record audio for seconds. In this recording circuit REM, when the recording switch R3W is closed, the control circuit C
It is connected to the microphone 9 built in the breathtalk microphone 8 of the transceiver 7 via C and the transmission/reception switching means 15, and is activated when the breathtalk switch 10 of the breathtalk microphone 8 is closed, thereby closing the recording switch R3W. Messages for 1M and 1M are recorded (for example, ``This is O○maru, I beg for rescue.''), but if the total recording time exceeds 2 seconds, recording will be stopped.
If the recording time is less than 2 seconds, null (silence) is recorded for the remaining time.

Each step surrounded by a chain line S corresponds to the control output generation means 3, and also serves as a detection output confirmation means. The output of the receiving circuit 2 is passed through three pulse interval confirmation means: a pulse interval of 0.8 seconds or less, a pulse interval of 1.2 seconds or less, and a pulse interval of 5 seconds or less, and the pulse from the handset 1 is 1 second or less. If it exceeds ±20%, the interference indicator lamp IL will blink according to the step surrounded by the chain line ■ in the figure to indicate that the device is not operating normally due to interference from a nearby consort ship using a slave unit of the same frequency. , when the pulse from the child 481 is interrupted for 5 consecutive seconds, a control output is generated, triggering and starting the engine stop timer EST,
The reproducing circuit PBM of the mesage generating means 5 is activated, and this output is applied to the sounding means 6 consisting of a low frequency amplifier and a speaker to generate sound, and the previously recorded mesosage is repeatedly output from the speaker. This will continue until the beam center switch 18 (P4) is closed.

The sounding means 6 may be replaced by so-called in-ship broadcasting equipment installed to communicate with nearby consort ships by voice.

The step surrounded by the chain line E is for detecting and stopping the engine rotation, and when the engine stop timer EST times out, the engine rotation detection circuit ERD is checked.
If the engine is running, trigger the timer means 4 to start it. P3) Make sure that the test switch is not closed, and drive the relay circuit RyC to close the engine stop relay contact E S'P. An engine stop signal is output, and the engine stop means (not shown) connected to the engine stop relay contact output is actuated to stop the engine, and the regeneration circuit PBM and sound generation means 6 are actuated to turn on the speaker as described above. Repeatedly outputs the previously recorded message. (P5, P6) As is clear from the figure, if the engine is stopped, this state will be maintained until the reset switch 18 is closed.

If the timer means 4 time-amps (P7), check that the reset switch 18 is not closed (P8)
, the transmission/reception switching means 15 is switched and the previously recorded message is transmitted from the transceiver 7.

In this embodiment, as shown in FIG. 3, an SOS generation circuit 505M is attached to the transmission/reception switching means 15 as shown in the figure, and the SOS signal and the message recorded in the recording circuit REM are alternately transmitted. I have to.

The stamps surrounded by chain lines T are steps for the test circuit operated by the test switch, and when the test switch TSW is closed, when the timer means 4 is activated, the test confirmation lamp TL is lit. This indicates that the device is operating, and when the reset switch is closed, the device returns to its initial state. Therefore, the engine does not stop because the timer means 4 is only activated and no engine stop signal is output.

Furthermore, if you want to perform a thorough test, you can stop the output of the engine stop signal, although it is a little more complicated, and stop the output of the engine stop signal.
It is easy to light the test H1li recognition lamp without closing the circuit of the breath talk switch 10 in step 5.

As mentioned above, this embodiment is equipped with a recording circuit using a semiconductor element, so that the user can record any #nuisance message for a certain period of time, making it easier to identify the sender and more quickly record the message. Since it is equipped with a test switch TSW, you can test the device before starting work and operate with peace of mind.
If there is a consort ship with the same frequency at a close distance by PRc, it is possible to know that there is interference by the lighting of the interference indicator lamp IL and take appropriate measures, making it suitable as a distress signal transmitting device.

Furthermore, since this embodiment is equipped with an engine stop relay contact output ESO, if the boat's engine is stopped or the boat's rudder is turned using this output and the boat falls off, it becomes easier to swim back to the boat.

As described above, in the case where an operator (worker) falls into the sea, when it is detected that the radio waves from the sub-equipment have been cut off, the transceiver installed on the ship
The system automatically activates the engine and sends a distress signal, and also automatically starts the engine to make it easier to return to the ship. If the operator (worker) returns to the ship within this time, he/she will know from the sound produced by the sounding means 6 that the device is operating, and will immediately return the device to its initial state by operating the reset switch 1B. The transmission of the distress signal can be stopped by the user, thus preventing the transmission of unnecessary distress signals, and the operator can operate with peace of mind by installing this device and wearing the handset 1 of this device. It is something that will give you the best results you can.

It should be noted that it is obvious that the timer, the circuit for logical judgment, the circuit for confirming the Norms interval, etc. can be replaced with the microprocessor.
