Abstract
Abstract of the Disclosure An alarm device for use with two engines, typically a pair of outboard motors attached to a boat is described. Each engine is provided with at least one sensor adapted to detect an abnormal condition, such as cooling water flow or oil temperature. The sensor output(s) are used as the input to a pair of warning devices, one for each engine, which typically will use a voice synthesizer to provide an audible warning. An output display is also provided, which is both able to indicate in which motor the abnormality has been detected, and also to discriminate between abnormality outputs arriving closely together from both engines. The audible warning for the second output to arrive is delayed until the warning for the first to arrive has been completed.
Description
VOICE ALARM OUTPUT DEVICE FOR OUTBOARD MOTOR
FIELD OF THE INVENTION
This invention relates to a voice alarm output device for an outboard motor and, more particularly, to a voice alarm output device which can operate effectively when used with a pair of outboard motors.
~ACKGROUND OF THE INVENTION
In a heretofore-used ala~m method for the handling of an outboard motor, the driver i5 signaled by a predeter-mined device such as a buzzer when a prepared sensor detects the occurrence of one of various kinds of ~bnormal states, such as one in which the amount of oil in an oil tank in a separate-oiling system decreases to a caution level, one in which the circu:Lation of cooling water through a cylinder jacket is stopped, or one in which an engine oil filter is clogged so that the oil is stopped from flowing.
This type of alarm does not clearly indicate the position of the occurrence of the abnormality, the cause of the abnormality, etc. For this reason, various alarm output-display methods have recently been developed in order to definitely display the position and cause of an . ~b`
, '' : ,. - .
z abnormality, measures for dealing with the abnormality, and so forth. The inventor of the present invention has also proposed a new alarm display method which can be used with an outboard motor and which uses voices to announce a detected abnormality.
The alarm display method using voices provides clear and understandable information. However, if this method i5 applied to a situation involving a pair of outboard motors, it is difficult to determine to which motor the voice announcing an abnormality relates.
It is thus an object of the present invention to provide a voice alarm output device which avoids this problem of the conventional device a~d makes it possible to clearly recognize to which motor the voice announcing an abnormality relates.
SUMMARY OF THE INVENTION
To this end, the present invention provides a voice alarm output device for a pair of outboard motors, includ-ing for each engine a plurality of sensors having a irst sensor ~or detecting a cooling water abnormality and a second sensor for detecting an oil level abnormality; a voice synthesis circuit for each engine which is supplied with an output from each of the sensors and outputs a warning of each detected abnormal state in the form of a voice signal; a left-right output display setting circuit coupled to outputs o~ the voice synthesis circuits provided in the outboard motors; and a lighting display sect~on adapted to provide a display indicating which o~ the voice synthesis circùits is producing a voice signal. If a sensor relating to a first of the outboard motors produces an output just before a sensor relating to a second o~ the outboard motors produces an output, the left-right output display setting circuit temporarily inhibits the output o~
a voice signal by the synthesis circuit relating to the second o~ khe outboard motors until the output of a voice 'g~qL2 signal by the synthesis circu;t relating to the first of the outboard motors is completed.
Thus, in its broadest embodiment this invention seeks to provide an alarm apparatus adapted for use with two engines comprising in combination: at least a first sensor adapted to detect an abnormal condition in a first engine;
at least a second sensor adapted to detect an abnormal condition in a second engine;
first means coupled to each of said sensors for lo providing an operator perceptible warning of an abnormal condition in one of said engines in response to detection thereof by one of said sensors;
second means coupled to said first means for providing, in association with each operator perceptible warning provided by said first means, an operator perceptible indication of which of said engines is experiencing the abnormal condition detected by one of said sensors; and third means responsive to detection of a first abnorrnality by one of said sensors associated with one of said engines just before detection of a second abnormality by another of said sensors associated with the other of said engines for delaying the output of the operator perceptible warning for the second abnormality until after completion of the operator perceptible warning for the first abnormality.
Preferably, the operator perceptible warning is an oral warning which, conveniently, is generated by a voice synthesizer.
Alternatively, the operator perceptible warning is a visual indication, such as a light emitting device.
Preferably, the alarm apparatus further includes a fourth means responsive to detection of an abnormality by at least one of said sensors to reduce the speed of either the engine in which the abnormality is detected, or of both engines, in response -to the detected abnormality.
- 3a -BRIEF DESCRIPTION OF THE DRAWINGS
An embodiment of the present invention will be described below with reference to Figures 1 to 3, in which:
Figure 1 is a schematic block diagram of a device which embodies the present invention;
Figure 2 is a flow chart of the operation of the device shown in fig. l; and Figure 3 is a diagrammatic view of a boat in which the device shown in Figure 1 is actually installed.
DETAILED DESCRIPTION
In the drawings, reference numerals 1 and 2 designate voice synthesis circuits, 12 and 22 oil level switches, 13 and 23 each designate a water sensor or first sensor, 14 and 24 each designate an oil float sensor or second sensor, 30 a left/right output display setting circuit, 39 a speaker, and 40 a lamp circuit.
Referring to Figure 1, reference charac-ter ~ denotes a right voice synthesis circuit associated with one (60 in Figure 3) of two outboard motors, while reference char~cter 2 denotes a left voice synthesis circuit associated with the other (70 in Figure 3) o~ the outboard motors.
An engine drive control section lO, an oil level switch 12 provided as a Eirst sensor, a water sensor 13 provided as a second sensor, and an oil flow sensor 14 provided as a third sensor are connected to an input stage of the right voice synthesis circuit 1. The right voice synthesis circuit 1 is thereby supplied with sensor signals necessary for Eorming a voice s~vnthesis output. A refer-ence character 16 denotes an input line for an engine rotation signal, and reference character 17 denotes an input line for a rotation limit signal.
%
The engine rotation signal on line 16 is present when the shaft of engine 60 is rotating, and the rotation limit signal on line 17 is present when the speed of engine 60 is being limited to a selected value. These two signals and the circuits which produce them are known and not in and of themselves a part of the present invention, and are therefore not discussed here in detail. Suitable circuits are disclosed, ~or example, in U.S. Patent No. 4 755 790.
Similarly, another engine drive control section 20, an oil level switch 22 provided as a first sensor, a water sensor 23 provided as a second sensor, and an oil flow sensor 24 provided as a third sensor are connected to an input stage of the other voice synthesis circuit 2. A
reference character 26 denotes an input line for an engine rotation signal, and reference character 27 denotes an input line for a rotation limit signal.
Each of the voice synthesis circuits 1 and 2 is pre~erably a conventional microprocessor circuit which includes conventional and not-illustrated components such as an input/output interface, a central processing unit or C~U, a read only memory or ROM, and so forth.
The output stages of the voice synthesis circuits 1 and 2 are coupled to a le~t/right output display setting circuit 30.
The left/right outpu~ display setting circuit 30 has-two relay circuits 31 and 32, and contact switches 31a and 32a ~or the relay circuits 31 and 32. Each o~ the relay circuits 31 and 32 is connected to priority output lines and priority input lines ~rom the input/output inter~ace provided in each o~the voice synthesis circuits 1 and 2.
There~ore, as will be described later, the relay circuits 31 and 32 can be simultaneously operated by control signals 2~
(selective drive signals corresponding to voice output signals) output from the voice synthesis circuits 1 and 2.
The contact switch 3la oparates to select a speaker output line from one of the voice synthesis circuits 1 and 2, and thereby output to a speaker 39 one of respective voice output signals supplied to the circuit 30 by the circuits 1 and 2. The other contact switch 32 a operates substantially simultaneously with the operation of the contact switch 31a so as to light up one of two pilot lamps lo RP and LP in synchronism with the voice output. A ref-erence character 40 denotes a lighting display section having the pilot lamps RP and LP.
The engine drive control section 10 corrssponding to one of the outboard motors includes, as shown in Figure 1, an ignition switch lOA, a relay lOB for a starter, a neutral switch lOC, a magnetoelectronic ignition coil lOD, a diode lOE, and an emergency switch lOF. A reference character 50 denotes a battery common to all of the system.
Similarly, the engine drive control section 20 corresponding to the other outboard motor includes, as shown in Figure 1, an ignition switch 20A, a relay 20B for a starter, a neutral switch 20C, a magnetoelectronic ignition coil 20D, diode 20E, and an emergency switch 20F.
The operation of each sec:tion of this embodiment will be described below.
The neutral switches are provided as a safety mech-anism, in order to prevent.each starter motor ~rom being actuated if the associated engine is not in neutral when the ignition switch lOA or 20A is turned from "ON" to "START". Signals which represent potentials at the opposite terminals of the neutral switches lOC and 20C are supplied to the voice synthesis circuits 1 and 2. only if an engine is in neutral is the associated neutral switch closed so that a current from the battery can flow through the relay to start the starter motor. ~t t~is time, the difference between the potentia~s at the opposite terminals of the neutral switch lOC or ~OC is approximately equal to zero, or is a small voltage drop, and the voice synthesis circuit thus detects the neutral state and does not issue any alarm.
If the ignition switch lOA or 20A is turned to the starting position when the engine is not in neutral, the potential difference between the opposite terminals of the associated neutral switch lOC or 20C becomes approximately equal to the battery voltage, because the neutral switch is in the off state. At this point, the starter motor is not actuated, of course. After detecting this potential difference, the voice synthesis circurit 1 or 2 determines that the associated engine is not in neutral, and outputs a vocal statement which reminds the operator to "set the gear to neutral".
The emergency switches lOD and 20D constitute another safety mechanism which instantaneously stops the engines when, during cruising, the driver accidentally falls overboard, and they are connected in parallel with the magnetoelectronic ignition coils (capacitor charge coils in the case of a capacitive discharge ignition) lOD and 2OD.
The emergency switches lOF and 20F are each connected at one end to one of the voice synthesis circuits 1 and 2.
When the engines start to rotate, rotation signals indicat-ing that rotation is occurring are supplied via the signal lines 16 and 26 to the voice synthesis circuits 1 and 2.
The emergency switch lOF or 20F is in the "O~F" state while a cap thereof wi~h an a~tached rope is disposed on a swltch body thereof, and becomes "ON" and bypasses the ignition coil when the cap is removed ~rom the switch body.
If, when the starter motor is actuated in order to start the engine, the cap of the emergency switch lOF or 20F is not disposed on the body thereof or if the circuit portion after the diode lOE ~on the side of the cathode) is short-circuited, sparking is not effected because the ignition coil is bypassed, so that the engine cannot be started. At this time, the connection point to the voice synthesis circuit 1 or 2 becomes a "low level", and an abnormal state of the stop circuit is determined, thereby initiating the output of a vocal alarm. The cap of the emergency switch lOF or 20F is normally attached to the switch body. If there is no circuit abnormality, this portion of the voice circuit becomes a "high level", and the normal state is determined so that no voice is output.
In the case of outboard motors of a two-cycle separa-tion oiling type, oil tanks are provided to hold oil which is supplied to the engines by oil pu~ps. If the amount of oil in either oil tank is reduced to a caution level, the oil level switch 12 or 22 present in the tank is turned on.
This switch is also connected to the voice synthesis circuit 1 or 2. The level at the connection point to the voice synthesis switch l or 2 becomes a "low level" in response to the on state of the oil level switch, thereby outputting a voice which indicates that "oil has reached the caution level". To effect in such a case a more positive alarm, a method of controlling the engine speed is usually adopted, and is e~fected by a known circuit which is not illustrated. A signal used ~or this purpose is supplied as a rotation limit signal to the voice synthesis circuit l or 2 via the signal line 17 or 27. In response to this, a vocal statement such as "reduce engine speed'' is generated.
I~, during cruising, cooling water is stopped ~rom circulating through each cylinder jacket because o~ some abnormality, ~he water sensor 12 or 23 turns on. Since the sensor is connected to the voice synthesis circuit 1 or 2, the level at this connection point becomes a "low level", as was the case for the actuated oil sensor, and a cooling water abnormallty is determined, thereby generating a vocal 1i,r~,2~L~
output alarm indicating the cooling water abnormality.
Similarly, at this time, the engine speed limitation is effected by a known circuit which is not illustrated. When a rotation limit signal is supplied to the voice synthesis circuit 1 or 2 via the line 17 or 27, a vocal statement such as "reduce engine speed" is genarated.
If, in the case of outboard motors of the two-cycle separation oiling type, the flow of oil is limited within a supply passage between the oil tank and the engine by, for lo example, clogging of an oil filter, the oil ~low sensor 14 or 24 turns on. The corresponding point at which the associated voice synthesis circuit is connected to this sensor becomes a "low level", and an;oil flow abnormality is detected, thereby causing generation of a vocal output alarm. Similarly, at this time, the engine speed limita-tion is also effected in a known manner by a not-il-lustrated circuit. When a rotation limit signal is supplied to the voice synthesis circuit 1 or 2 via the line 17 or 27, a vocal statement such as "reduce engine speed"
is generated.
The operation of the thus-arranged abnormality detection systems will be described below with respect to the case in which one of the v~ice synthesis circuits 1 and 2 is supplied with some abnormality signal.
~f, for example f the oil level switch connection point of the voice synthesis circui~ 1 (for engine R) changes from a "high" level to "low" level, an abnormal state is of course detected, and a priority output signal is supplied from the voice synthesis circuit 1 to the voice synthesis circuit 2. The voice output operation oP the voice synthesis circuit 2 is there~y temporarily inhibited.
Further, at this time, a current Prom the battery 8 flows via the ignition switch lOA through the coil 31A oP the relay 31 to the voice synthesis circuit 2 so that the coll 31~ iæ excited an~ the contact 31a engages the R terminal so that the speaker output line from circuit 1 is connected to the speaker 39.
The speaker output line from the voice synthesis circuit 1 is thus connected to the speaker 39, thereby outputting a voice which indicates that "the oil level has reached the caution level". Also, a current from the battery 50 flows via the ignition switch lOA through the coil 32A of the relay 32 to the voice synthesis circuit 2.
The coil 32A is thereby excited, the contact 32a is moved lo to the R-side, and a battery current flows via the ignition switch lOA to the contact R of the relay 32, then through a resistance and the light emitting diode RP, and then to ground. The light emitting diode isjthereby lighted up to indicate that the voice output corresponds to the right engine. In this case, the relay may be of an ordinary type. IIowever, keep relays can also be used, in which case the speaker 39 is kept connected to the circuit 1 and the light emitting diode ~ of circuit 40 is kept in the lighted state until the next input is supplied because, once this type of relay turns "ON", it is maintained in the on state even after the power has ~een cut off. It is then not necessary for the driver to see, while a vocal statement is being output, the light emittlng diode 40 provided as a pilot lamp in order to know from which circuit the voice is - supplied. He can confirm it afterward withaut haste since the diode stays lit. It is thus possible to con~irm at a glance to which engine the voice synthesis circuit con-nected to the speake~ at the present time pertains.
If an abnormality signal is input into the voice synthesis circuit 2, a priority outpu~ signal is instan-taneously supplied from the voice synthesis circuit 2 to the voice synthesis circuit l. The voice output operation of the voice synthesis circuit 1 is thereby temporarily inhibited, and a current from the battery 50 flows via the ignltiQn switch 10~ ~hrough the coil ~lB o~ the relay 31 to the voice synthesis circuit 1, so that the coil 3lB is excited and the contact 3la engages the L terminal. The speaker output line from the voice synthesis circuit 2 is thereby connected to the speaker 39, and a voice supplied from the voice synthesis circuit 2 is output through the speaker 39. Also, a current from the battery 50 flows via the ignition switch lOA through the coil 32B of the relay 32 to the voice synthesis circuit 1. The coil 32B is thereby excited, and the contact 32a is connected to the L
lo terminal.
A battery current then flows via the ignition switch lOA to the contact L of the relay 32, and then through the resistance and the light emitting diPde LP to ground. It i5 thereby possible to confirm that the voice synthesis circuit 2 of the left engine is operating. If abnormality signals are input into the voice synthesis circuits 1 and 2 with almost the same timing, the above-described operation i5 performed with priority for the circuit which has been supplied with the signal first, even with a slight prece-dence. When the first voice output has been completed, the other circuit rapidly takes over and outputs its voice output. The display device in the above description uses light emitting diodes, but any other type of display, such as one using lamps, is acceptable.
The overall operation of the voice synthesis circuits will be described below mainly with reference to the flow chart of Figure Z.
After the engines have ~een started and the amount of oil in the oil tank of the right engine has reached the caution level, a signal is supplied from the oil level switch to the voice synthesis circuit 1, and a determina-tion is made (at STl) as to whether or not the voice synthesis circuit 1 (for engine R) has been supplied with an abnormality signal. If YES, a voice which indicates that the oil level has reached the caution level is output (ST2). At the same time, the operation of temporarily stopping the voice output operation of the voice synthesis circuit 2 is performed.
A determination is then made as to whether or not the voice output effected in ST2 has been completed (ST4). If it is not completed, the same determination is performed after each answer of N0 unt-l the voice output is com-pleted. If it is completed, YES is given and the suspen-sion of the voice output operation of the voice synthesis circuit 2 is canceled (ST5).
A determination is then made (ST6) as to whether or not the amount of oil has reached the caution level with respect to the voice synthesis circu,it 2 (for engine L), or whether or not the voice synthesis circuit 2 has been supplied with a different type of abnormality signal. If N0, the process returns to the above-mentioned determina-tion (STl) of whether or not the voice synthesis circuit 1 has been supplied with an abnormality signal. In the case of YES, an alarm voice corresponding to the abnormality signal is output (ST7~. The process then returns to the first determination (STl) of whether or not the voice synthesis circuit 1 has been supplied with an abnormality signal. If it has been supplied with an abnormality signal, YES is given and the foregoing sequence is repeated again. Tn the case of N0, the process proceeds to the next determination (ST8~.
If, for example, the~flow o~ cooling water to the water jacket af the cylinder of engine L is stopped due to some cause, the voice synthesis circuit 2 (~or engine L) is supplied with a signal from the sensor. YES i5 given a~ter the determination (ST8) of whether or not the voice synthesis circuit 2 has been supplied with an abnormality signal, and a voice of warniny o~ a cooling water abnor-mality is output (ST9), At the same time, the voice output 2~;~
operation of the voice synthesis circuit 1 is temporarily inhibited.
Next, a determination is made as to whether or not the voice output e~fected in ST9 has been completed tST11), and the same determination is repeated until the output operation is completed. When YES is given at the time of completion, the suspension of the voice output operation of ¦ ths voice synthesis circuit l effected in ST9 is canceled , (ST12).
I 10 A determination is then made as to whether or not the voice synthesis circuit 1 (for engine R) has been supplied with a signal representing a cooling water abnormality or a different type of abnormality (ST13);. If NO, the process returns to the determination (ST8) of whether or not the voice synthesis circuit 2 has been supplied with an abnormality signal. If YES, an alarm voice corresponding to the content of the abnormality signal is output ~ST14~, and the process thereafter returns ~o the original deter-mination (ST8). If the voice synthesis circuit 2 is at this time being supplied with an abnormality signal, the foregoing sequence is repeated due to an answer of YES. In the case of NO, the process returns to the first determina-tion (STl) of whether or not the voice synthesis circuit l (for engine R) has been supplied with an abnormality signal.
This process is performed until the operation of the engines is terminated.
If one of the pair of voice synthesis aircuits i5 supplied with an abnormality signal, the operation of the other voice synthesis circuit is temporarily stopped until the voice output from the former is completed. The voice from one of the voice synthe i5 circuits which has been supplied an abnormality signal firs~ i5 output first with priority. In other wor~s, if one voice qynthesis circuit xeaelves an abnormall~y ~ignal and -t~en, a moment later, ~ '9~
the other voice synthesis circuit is supplied with an abnormality signal, the latter circuit is made to wait until tha voice output from the former circuit is com-pleted. Thereafter, the voice from the latter is output.
It is thereby possible for the driver to recognize ~oth voice outputs without any confusion.
Figure 3 is a diagrammatic view of a boat having dual outboard motors to which the voice synthesis circuits are applied.
In the device having the above-described construction and function in accord with the present invention, when a sensor input relating to one of the outboard motors occurs just bef~re a sensor input for the o~her, the first sensor input is handled with priority while the second sensor input is temporarily suspended, thereby eliminating the possibility of the occurrence of a malfunction at the time of a voice output. Since the pilot lamps are lighted up in correspondence with the left and right outboard motors, the outboard motor to which a voice output display relates can be easily recognized. The present invention thus provides a voice alarm output device for outboard motors superior to any device heretofore known.
FIELD OF THE INVENTION
This invention relates to a voice alarm output device for an outboard motor and, more particularly, to a voice alarm output device which can operate effectively when used with a pair of outboard motors.

Thus, in its broadest embodiment this invention seeks to provide an alarm apparatus adapted for use with two engines comprising in combination: at least a first sensor adapted to detect an abnormal condition in a first engine;
at least a second sensor adapted to detect an abnormal condition in a second engine;
first means coupled to each of said sensors for lo providing an operator perceptible warning of an abnormal condition in one of said engines in response to detection thereof by one of said sensors;
second means coupled to said first means for providing, in association with each operator perceptible warning provided by said first means, an operator perceptible indication of which of said engines is experiencing the abnormal condition detected by one of said sensors; and third means responsive to detection of a first abnorrnality by one of said sensors associated with one of said engines just before detection of a second abnormality by another of said sensors associated with the other of said engines for delaying the output of the operator perceptible warning for the second abnormality until after completion of the operator perceptible warning for the first abnormality.
Preferably, the operator perceptible warning is an oral warning which, conveniently, is generated by a voice synthesizer.
Alternatively, the operator perceptible warning is a visual indication, such as a light emitting device.
Preferably, the alarm apparatus further includes a fourth means responsive to detection of an abnormality by at least one of said sensors to reduce the speed of either the engine in which the abnormality is detected, or of both engines, in response -to the detected abnormality.
- 3a -BRIEF DESCRIPTION OF THE DRAWINGS
An embodiment of the present invention will be described below with reference to Figures 1 to 3, in which:
Figure 1 is a schematic block diagram of a device which embodies the present invention;
Figure 2 is a flow chart of the operation of the device shown in fig. l; and Figure 3 is a diagrammatic view of a boat in which the device shown in Figure 1 is actually installed.
DETAILED DESCRIPTION
In the drawings, reference numerals 1 and 2 designate voice synthesis circuits, 12 and 22 oil level switches, 13 and 23 each designate a water sensor or first sensor, 14 and 24 each designate an oil float sensor or second sensor, 30 a left/right output display setting circuit, 39 a speaker, and 40 a lamp circuit.
Referring to Figure 1, reference charac-ter ~ denotes a right voice synthesis circuit associated with one (60 in Figure 3) of two outboard motors, while reference char~cter 2 denotes a left voice synthesis circuit associated with the other (70 in Figure 3) o~ the outboard motors.
An engine drive control section lO, an oil level switch 12 provided as a Eirst sensor, a water sensor 13 provided as a second sensor, and an oil flow sensor 14 provided as a third sensor are connected to an input stage of the right voice synthesis circuit 1. The right voice synthesis circuit 1 is thereby supplied with sensor signals necessary for Eorming a voice s~vnthesis output. A refer-ence character 16 denotes an input line for an engine rotation signal, and reference character 17 denotes an input line for a rotation limit signal.
%
The engine rotation signal on line 16 is present when the shaft of engine 60 is rotating, and the rotation limit signal on line 17 is present when the speed of engine 60 is being limited to a selected value. These two signals and the circuits which produce them are known and not in and of themselves a part of the present invention, and are therefore not discussed here in detail. Suitable circuits are disclosed, ~or example, in U.S. Patent No. 4 755 790.
Similarly, another engine drive control section 20, an oil level switch 22 provided as a first sensor, a water sensor 23 provided as a second sensor, and an oil flow sensor 24 provided as a third sensor are connected to an input stage of the other voice synthesis circuit 2. A
reference character 26 denotes an input line for an engine rotation signal, and reference character 27 denotes an input line for a rotation limit signal.
Each of the voice synthesis circuits 1 and 2 is pre~erably a conventional microprocessor circuit which includes conventional and not-illustrated components such as an input/output interface, a central processing unit or C~U, a read only memory or ROM, and so forth.
The output stages of the voice synthesis circuits 1 and 2 are coupled to a le~t/right output display setting circuit 30.
The left/right outpu~ display setting circuit 30 has-two relay circuits 31 and 32, and contact switches 31a and 32a ~or the relay circuits 31 and 32. Each o~ the relay circuits 31 and 32 is connected to priority output lines and priority input lines ~rom the input/output inter~ace provided in each o~the voice synthesis circuits 1 and 2.
There~ore, as will be described later, the relay circuits 31 and 32 can be simultaneously operated by control signals 2~
(selective drive signals corresponding to voice output signals) output from the voice synthesis circuits 1 and 2.
The contact switch 3la oparates to select a speaker output line from one of the voice synthesis circuits 1 and 2, and thereby output to a speaker 39 one of respective voice output signals supplied to the circuit 30 by the circuits 1 and 2. The other contact switch 32 a operates substantially simultaneously with the operation of the contact switch 31a so as to light up one of two pilot lamps lo RP and LP in synchronism with the voice output. A ref-erence character 40 denotes a lighting display section having the pilot lamps RP and LP.
The engine drive control section 10 corrssponding to one of the outboard motors includes, as shown in Figure 1, an ignition switch lOA, a relay lOB for a starter, a neutral switch lOC, a magnetoelectronic ignition coil lOD, a diode lOE, and an emergency switch lOF. A reference character 50 denotes a battery common to all of the system.
Similarly, the engine drive control section 20 corresponding to the other outboard motor includes, as shown in Figure 1, an ignition switch 20A, a relay 20B for a starter, a neutral switch 20C, a magnetoelectronic ignition coil 20D, diode 20E, and an emergency switch 20F.
The operation of each sec:tion of this embodiment will be described below.
The neutral switches are provided as a safety mech-anism, in order to prevent.each starter motor ~rom being actuated if the associated engine is not in neutral when the ignition switch lOA or 20A is turned from "ON" to "START". Signals which represent potentials at the opposite terminals of the neutral switches lOC and 20C are supplied to the voice synthesis circuits 1 and 2. only if an engine is in neutral is the associated neutral switch closed so that a current from the battery can flow through the relay to start the starter motor. ~t t~is time, the difference between the potentia~s at the opposite terminals of the neutral switch lOC or ~OC is approximately equal to zero, or is a small voltage drop, and the voice synthesis circuit thus detects the neutral state and does not issue any alarm.
If the ignition switch lOA or 20A is turned to the starting position when the engine is not in neutral, the potential difference between the opposite terminals of the associated neutral switch lOC or 20C becomes approximately equal to the battery voltage, because the neutral switch is in the off state. At this point, the starter motor is not actuated, of course. After detecting this potential difference, the voice synthesis circurit 1 or 2 determines that the associated engine is not in neutral, and outputs a vocal statement which reminds the operator to "set the gear to neutral".
The emergency switches lOD and 20D constitute another safety mechanism which instantaneously stops the engines when, during cruising, the driver accidentally falls overboard, and they are connected in parallel with the magnetoelectronic ignition coils (capacitor charge coils in the case of a capacitive discharge ignition) lOD and 2OD.
The emergency switches lOF and 20F are each connected at one end to one of the voice synthesis circuits 1 and 2.
When the engines start to rotate, rotation signals indicat-ing that rotation is occurring are supplied via the signal lines 16 and 26 to the voice synthesis circuits 1 and 2.
The emergency switch lOF or 20F is in the "O~F" state while a cap thereof wi~h an a~tached rope is disposed on a swltch body thereof, and becomes "ON" and bypasses the ignition coil when the cap is removed ~rom the switch body.
If, when the starter motor is actuated in order to start the engine, the cap of the emergency switch lOF or 20F is not disposed on the body thereof or if the circuit portion after the diode lOE ~on the side of the cathode) is short-circuited, sparking is not effected because the ignition coil is bypassed, so that the engine cannot be started. At this time, the connection point to the voice synthesis circuit 1 or 2 becomes a "low level", and an abnormal state of the stop circuit is determined, thereby initiating the output of a vocal alarm. The cap of the emergency switch lOF or 20F is normally attached to the switch body. If there is no circuit abnormality, this portion of the voice circuit becomes a "high level", and the normal state is determined so that no voice is output.
In the case of outboard motors of a two-cycle separa-tion oiling type, oil tanks are provided to hold oil which is supplied to the engines by oil pu~ps. If the amount of oil in either oil tank is reduced to a caution level, the oil level switch 12 or 22 present in the tank is turned on.
This switch is also connected to the voice synthesis circuit 1 or 2. The level at the connection point to the voice synthesis switch l or 2 becomes a "low level" in response to the on state of the oil level switch, thereby outputting a voice which indicates that "oil has reached the caution level". To effect in such a case a more positive alarm, a method of controlling the engine speed is usually adopted, and is e~fected by a known circuit which is not illustrated. A signal used ~or this purpose is supplied as a rotation limit signal to the voice synthesis circuit l or 2 via the signal line 17 or 27. In response to this, a vocal statement such as "reduce engine speed'' is generated.
I~, during cruising, cooling water is stopped ~rom circulating through each cylinder jacket because o~ some abnormality, ~he water sensor 12 or 23 turns on. Since the sensor is connected to the voice synthesis circuit 1 or 2, the level at this connection point becomes a "low level", as was the case for the actuated oil sensor, and a cooling water abnormallty is determined, thereby generating a vocal 1i,r~,2~L~
output alarm indicating the cooling water abnormality.
Similarly, at this time, the engine speed limitation is effected by a known circuit which is not illustrated. When a rotation limit signal is supplied to the voice synthesis circuit 1 or 2 via the line 17 or 27, a vocal statement such as "reduce engine speed" is genarated.
If, in the case of outboard motors of the two-cycle separation oiling type, the flow of oil is limited within a supply passage between the oil tank and the engine by, for lo example, clogging of an oil filter, the oil ~low sensor 14 or 24 turns on. The corresponding point at which the associated voice synthesis circuit is connected to this sensor becomes a "low level", and an;oil flow abnormality is detected, thereby causing generation of a vocal output alarm. Similarly, at this time, the engine speed limita-tion is also effected in a known manner by a not-il-lustrated circuit. When a rotation limit signal is supplied to the voice synthesis circuit 1 or 2 via the line 17 or 27, a vocal statement such as "reduce engine speed"
is generated.
The operation of the thus-arranged abnormality detection systems will be described below with respect to the case in which one of the v~ice synthesis circuits 1 and 2 is supplied with some abnormality signal.
~f, for example f the oil level switch connection point of the voice synthesis circui~ 1 (for engine R) changes from a "high" level to "low" level, an abnormal state is of course detected, and a priority output signal is supplied from the voice synthesis circuit 1 to the voice synthesis circuit 2. The voice output operation oP the voice synthesis circuit 2 is there~y temporarily inhibited.
Further, at this time, a current Prom the battery 8 flows via the ignition switch lOA through the coil 31A oP the relay 31 to the voice synthesis circuit 2 so that the coll 31~ iæ excited an~ the contact 31a engages the R terminal so that the speaker output line from circuit 1 is connected to the speaker 39.
The speaker output line from the voice synthesis circuit 1 is thus connected to the speaker 39, thereby outputting a voice which indicates that "the oil level has reached the caution level". Also, a current from the battery 50 flows via the ignition switch lOA through the coil 32A of the relay 32 to the voice synthesis circuit 2.
The coil 32A is thereby excited, the contact 32a is moved lo to the R-side, and a battery current flows via the ignition switch lOA to the contact R of the relay 32, then through a resistance and the light emitting diode RP, and then to ground. The light emitting diode isjthereby lighted up to indicate that the voice output corresponds to the right engine. In this case, the relay may be of an ordinary type. IIowever, keep relays can also be used, in which case the speaker 39 is kept connected to the circuit 1 and the light emitting diode ~ of circuit 40 is kept in the lighted state until the next input is supplied because, once this type of relay turns "ON", it is maintained in the on state even after the power has ~een cut off. It is then not necessary for the driver to see, while a vocal statement is being output, the light emittlng diode 40 provided as a pilot lamp in order to know from which circuit the voice is - supplied. He can confirm it afterward withaut haste since the diode stays lit. It is thus possible to con~irm at a glance to which engine the voice synthesis circuit con-nected to the speake~ at the present time pertains.
If an abnormality signal is input into the voice synthesis circuit 2, a priority outpu~ signal is instan-taneously supplied from the voice synthesis circuit 2 to the voice synthesis circuit l. The voice output operation of the voice synthesis circuit 1 is thereby temporarily inhibited, and a current from the battery 50 flows via the ignltiQn switch 10~ ~hrough the coil ~lB o~ the relay 31 to the voice synthesis circuit 1, so that the coil 3lB is excited and the contact 3la engages the L terminal. The speaker output line from the voice synthesis circuit 2 is thereby connected to the speaker 39, and a voice supplied from the voice synthesis circuit 2 is output through the speaker 39. Also, a current from the battery 50 flows via the ignition switch lOA through the coil 32B of the relay 32 to the voice synthesis circuit 1. The coil 32B is thereby excited, and the contact 32a is connected to the L
lo terminal.
A battery current then flows via the ignition switch lOA to the contact L of the relay 32, and then through the resistance and the light emitting diPde LP to ground. It i5 thereby possible to confirm that the voice synthesis circuit 2 of the left engine is operating. If abnormality signals are input into the voice synthesis circuits 1 and 2 with almost the same timing, the above-described operation i5 performed with priority for the circuit which has been supplied with the signal first, even with a slight prece-dence. When the first voice output has been completed, the other circuit rapidly takes over and outputs its voice output. The display device in the above description uses light emitting diodes, but any other type of display, such as one using lamps, is acceptable.
The overall operation of the voice synthesis circuits will be described below mainly with reference to the flow chart of Figure Z.
After the engines have ~een started and the amount of oil in the oil tank of the right engine has reached the caution level, a signal is supplied from the oil level switch to the voice synthesis circuit 1, and a determina-tion is made (at STl) as to whether or not the voice synthesis circuit 1 (for engine R) has been supplied with an abnormality signal. If YES, a voice which indicates that the oil level has reached the caution level is output (ST2). At the same time, the operation of temporarily stopping the voice output operation of the voice synthesis circuit 2 is performed.
A determination is then made as to whether or not the voice output effected in ST2 has been completed (ST4). If it is not completed, the same determination is performed after each answer of N0 unt-l the voice output is com-pleted. If it is completed, YES is given and the suspen-sion of the voice output operation of the voice synthesis circuit 2 is canceled (ST5).
A determination is then made (ST6) as to whether or not the amount of oil has reached the caution level with respect to the voice synthesis circu,it 2 (for engine L), or whether or not the voice synthesis circuit 2 has been supplied with a different type of abnormality signal. If N0, the process returns to the above-mentioned determina-tion (STl) of whether or not the voice synthesis circuit 1 has been supplied with an abnormality signal. In the case of YES, an alarm voice corresponding to the abnormality signal is output (ST7~. The process then returns to the first determination (STl) of whether or not the voice synthesis circuit 1 has been supplied with an abnormality signal. If it has been supplied with an abnormality signal, YES is given and the foregoing sequence is repeated again. Tn the case of N0, the process proceeds to the next determination (ST8~.
If, for example, the~flow o~ cooling water to the water jacket af the cylinder of engine L is stopped due to some cause, the voice synthesis circuit 2 (~or engine L) is supplied with a signal from the sensor. YES i5 given a~ter the determination (ST8) of whether or not the voice synthesis circuit 2 has been supplied with an abnormality signal, and a voice of warniny o~ a cooling water abnor-mality is output (ST9), At the same time, the voice output 2~;~
operation of the voice synthesis circuit 1 is temporarily inhibited.
Next, a determination is made as to whether or not the voice output e~fected in ST9 has been completed tST11), and the same determination is repeated until the output operation is completed. When YES is given at the time of completion, the suspension of the voice output operation of ¦ ths voice synthesis circuit l effected in ST9 is canceled , (ST12).
I 10 A determination is then made as to whether or not the voice synthesis circuit 1 (for engine R) has been supplied with a signal representing a cooling water abnormality or a different type of abnormality (ST13);. If NO, the process returns to the determination (ST8) of whether or not the voice synthesis circuit 2 has been supplied with an abnormality signal. If YES, an alarm voice corresponding to the content of the abnormality signal is output ~ST14~, and the process thereafter returns ~o the original deter-mination (ST8). If the voice synthesis circuit 2 is at this time being supplied with an abnormality signal, the foregoing sequence is repeated due to an answer of YES. In the case of NO, the process returns to the first determina-tion (STl) of whether or not the voice synthesis circuit l (for engine R) has been supplied with an abnormality signal.
This process is performed until the operation of the engines is terminated.
If one of the pair of voice synthesis aircuits i5 supplied with an abnormality signal, the operation of the other voice synthesis circuit is temporarily stopped until the voice output from the former is completed. The voice from one of the voice synthe i5 circuits which has been supplied an abnormality signal firs~ i5 output first with priority. In other wor~s, if one voice qynthesis circuit xeaelves an abnormall~y ~ignal and -t~en, a moment later, ~ '9~
the other voice synthesis circuit is supplied with an abnormality signal, the latter circuit is made to wait until tha voice output from the former circuit is com-pleted. Thereafter, the voice from the latter is output.
It is thereby possible for the driver to recognize ~oth voice outputs without any confusion.
Figure 3 is a diagrammatic view of a boat having dual outboard motors to which the voice synthesis circuits are applied.
In the device having the above-described construction and function in accord with the present invention, when a sensor input relating to one of the outboard motors occurs just bef~re a sensor input for the o~her, the first sensor input is handled with priority while the second sensor input is temporarily suspended, thereby eliminating the possibility of the occurrence of a malfunction at the time of a voice output. Since the pilot lamps are lighted up in correspondence with the left and right outboard motors, the outboard motor to which a voice output display relates can be easily recognized. The present invention thus provides a voice alarm output device for outboard motors superior to any device heretofore known.
