[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an emergency avoidance signaling device used in a designated driving lesson of a motorcycle, for example, in a driving school.

[0002]

[Prior art]

 At the driving training school, a practice called "emergency avoidance" is conducted as a designated training as a driving training subject for obtaining a motorcycle license. This is because when there is a sudden situation such as an accident on a general road, or when it is necessary to pay attention to driving due to large irregularities on the road surface, motorcycles should be installed at the left or right end of the road to avoid this. This is a training for avoiding while braking in advance.In the above-mentioned designated training, conventionally, for example, a traffic light with two lights was installed at the intersection of the T-junction of the driving training course in the driving school, and When a trainee who rides on a motorcycle arrives at a predetermined position, a trainee or other staff member manually turns on or off one of the lights, or instead of installing a traffic signal, the staff member near the intersection He was instructing the trainee in the avoidance direction by waving a flag in his odor.

[0003]

[Problems to be solved by the device]

 However, in any of the above cases, at least one staff member is required.For example, at the time of rainfall, it is necessary for the staff member to stand in the shade and to be in the rain, and to operate the traffic light and the flag, requires considerable skill. However, when an unfamiliar person sent instructions, the trainees were sometimes confused.

The present invention has been made in consideration of the above-mentioned matters, and an object thereof is to provide a method of avoiding a vehicle traveling on a road in a predetermined direction without manual labor. It is to provide an emergency avoidance signaling device capable of carrying out.

[0005]

In order to achieve the above object, an emergency avoidance signaling device of the present invention includes a power supply unit, an electronic timer circuit, a turn signal device, and an ultrasonic wave for detecting a vehicle passing on the road. A switch circuit including a sensor, and when the ultrasonic sensor detects a vehicle traveling in a specific direction, the switch circuit operates, and the direction indicating device operates for a predetermined time set by the electronic timer circuit. It is configured to indicate to the avoidance direction.

The power supply unit may include a power supply rectifier circuit that converts alternating current into direct current. Further, the power supply unit may be configured by a type in which a battery is loaded. As the ultrasonic sensor, various types such as a blocking type and a reflection type which are already known per se can be used, but the reflection type is preferable for simplifying the wiring. As the direction indicating device, a voice generator or the like can be used in addition to a traffic signal.

[0007]

[Action]

 In the emergency avoidance signaling device configured as described above, for example, the traffic signal is provided in front of the vehicle traveling on the road, and the ultrasonic sensor is provided in front of the traffic signal. The traffic light is always off. When the motorcycle reaches a predetermined position in front of the traffic light, the ultrasonic sensor detects this and the switch circuit operates to turn on one lamp of the traffic light for a predetermined time. The driver of the motorcycle can avoid the motorcycle by following this lighting display.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an example in which an emergency avoidance signaling device according to an embodiment of the present invention is provided in a training course of a car driving school. In this figure, 1 is a T-shaped road consisting of courses 2, 3 and 4. At the intersection of the course, a traffic light 5 having _two lights L ₁ and L ₂ toward the course 2 is provided. A control box 6 controls the operation of the traffic light 5 (the internal structure of which will be described later) and is installed near the traffic light 5.

Reference numeral 7 is a reflection type ultrasonic sensor which is provided on the course 2 in front of the traffic light 3 and at an appropriate distance from the traffic light 5 (for example, 10 m before). The ultrasonic sensor 7 detects a motorcycle B traveling on the course 2 in the direction of the traffic light 5 (arrow direction) when it enters the sensing area of the ultrasonic sensor 7 on the course 2.

FIG. 2 is a circuit diagram showing an example of the electrical configuration of the control unit provided in the control box 6, in which 10 is an AC power supply connection plug, and 11 is the outside of the control box 6. This is a step-down transformer provided via a power switch 12 and a fuse 13 provided in the. The transformer 11 adjusts the voltage of AC100V to 12V.

Reference numeral 14 denotes a power supply rectification circuit provided on the output side of the transformer 11, a rectification circuit 16 formed by connecting a plurality of diodes 15 in a bridge, a three-terminal regulator 17 provided on the output side of the rectification circuit 16, and an electrolytic capacitor. 18, a smoothing capacitor 19 and the like. P and N are a positive power supply line and a negative power supply line, respectively. As is apparent from this description, a power supply rectifier circuit that converts alternating current into direct current is included as the power supply unit of the control unit.

Reference numeral 20 denotes an electronic timer circuit provided on the output side of the power supply rectification circuit 14 via a switch circuit 21 which will be described later. The electronic timer circuit 20 operates the traffic light 5 for a predetermined time, and includes two transistors 22 and 23. , An electrolytic capacitor 24, a variable resistor 25 (the resistance value of which changes when an operating time setting knob provided on the surface of the control box is operated), resistors 26 to 28, and the like.

In the switch circuit 21, the normally open contact 7a of the ultrasonic sensor 7 is connected between the collector of the transistor 22 and the negative power supply line N, and two relays 29 and 30 parallel to each other are described later. It is connected in series to the collector of the transistor 22 and the normally open contact point 7a via a switching contact 32c of a relay 32 provided in the flip-flop circuit 31. One relay 29 is connected to the positive power supply line P via the normally closed contact 30b of the other relay 30 and is connected to the normally open contact 7a and the transistor 22 via its normally open contact point 29a _1. Connected to the collector. Further, the other relay 30 is connected to the positive power supply line P via the normally closed contact 29b of the one relay 29, and is connected to the normally open contact 7a and the transistor 22 described above via its own normally open contact 30a ₁ . It is connected to the collector.

The flip-flop circuit 31 includes two transistors 33 and 34, capacitors 35 and 36, resistors 37 to 39, and the like. A relay 32 is provided between the collector of one transistor 33 and the positive power supply line P. Is provided.

The ultrasonic sensor 7 intermittently emits ultrasonic waves in pulses, and the ultrasonic waves obtained by the starting circuit 71 are emitted from the transmitting section of the transceiver 72, which hits the motorcycle B. The receiving portion of the transceiver 72 receives the reflected light and amplifies it by the amplifier circuit 73. When the received level is equal to or higher than the level set by the level detection circuit 74, the relay circuit 75 operates to operate the normally open circuit. It is configured to close the contact 7a.

Further, light L _1, L ₂ of the traffic 5, downstream of the power switch 12 Te primary odor of the transformer 11, through the normally open contact 29a _2, 30 a ₂ of the relay 29, 30 It is connected to an AC power source.

In the emergency avoidance signaling device configured as described above, when the power switch 12 is on and the motorcycle B is not present on the course 2 between the ultrasonic sensor 7 and the traffic signal 5, the ultrasonic sensor 7 operates as follows. Since the motorcycle B is not detected and therefore the normally open contact 7a of the ultrasonic sensor 7 is in the open state, in the electronic timer circuit 20, one transistor 22 is off and the other transistor 23 is Only the base current flows, and the capacitor 24 is charged with + on the collector side of the transistor 22 and − on the base side of the transistor 23. At this time, in the switch circuit 21, the operation of the flip-flop circuit 31 causes the switching contact 32c of the relay 32 to repeat an on-off operation and an off-on operation at regular intervals.

Then, as shown in FIG. 2, when the switching contact 32c is turned on to the relay 29 side, the ultrasonic sensor 7 detects the motorcycle B traveling on the course 2 in the arrow direction. Then, the normally open contact 7a of the switch circuit 21 is closed, whereby the relay 29 is operated and the normally open contacts 29a ₁ and 29a ₂ are closed, and the operation of the relay 29 is set by the electronic timer circuit 20. It is held for a time, during its, by the AC100V to one of the light L ₁ of the traffic 5 is supplied, rye DOO L _1, for example light blue. As a result, the motorcycle B turns left at the intersection and proceeds in the direction of the course 3. At this time, the normally closed contact 29b of the relay 29 is opened so that the other relay 30 does not operate.

Then, the collector voltage is applied to the transistor 23 via the resistor 27, and the collector of the transistor 22 is grounded. On the other hand, the voltage of the capacitor 24 is applied to the base of the transistor 23 in reverse bias, Transistor 23 turns off and its collector voltage rises, which causes transistor 22 to turn on with sufficient base current through resistors 27, 28 to turn on.

As described above, when the motorcycle B turns to the left, the normally open contact 7a of the ultrasonic sensor 7 is once turned off. However, regardless of this operation, the transistor 22 is turned on and the relay 29 continues to be turned on. Since a current flows, the normally-open contacts 29a ₁ and 29a ₂ are turned on, and the light L ₁ in the traffic light 5 continues to light.

Then, the electric charge stored in the capacitor 24 is discharged through the transistor 22 that is on, the variable resistor 25, and the resistor 26, so that the base potential of the transistor 23 in the off state rises with the passage of time. Then, when this potential rises to a certain value, the transistor 23 turns on, its collector potential drops, and the base potential of the transistor 22 drops, so that the transistor 22 turns off. Since the current is cut off and the normally open contacts 29a ₁ and 29a ₂ are opened, the lighting of the light L ₁ is stopped.

As can be understood from the above description, when the transistor 22 that has been turned on is turned off again, the lighting of the light L ₁ in the traffic light 5 is stopped, but the time when the transistor 22 is turned off remains in the capacitor 24. It is closely related to the time (time constant) required for discharging the stored charge, and its setting can be arbitrarily adjusted by appropriately changing the value of the variable resistor 25. Therefore, the operating time of the traffic light 5 can be set by appropriately operating the operating time setting knob provided in the control box 6, and can be set within the range of, for example, 1 to 160 seconds.

When the switching contact 32c is turned on to the relay 30 side and the motorcycle B traveling in the arrow direction on the course 2 is detected by the ultrasonic sensor 7, the relay 30 is turned on. When the relay 30 operates and the normally open contacts 30a ₁ and 30a ₂ are closed, the relay 30 holds its operation for a time set by the electronic timer circuit 20, and the light L ₂ of the traffic light 5 is turned on. Therefore, at this time, the motorcycle B turns right at the intersection.

In the above-described embodiment, the traffic light 5 is used as the turn signal device, but a voice generator is used to automatically send a message such as "turn left" or "turn right". The driver of the motorcycle B may be informed.

Further, the traffic signal 5 and the control box 6 may be integrated. Further, the control box 6 and the ultrasonic sensor 7 may be connected by a signal line such as a cable, but both 6 and 7 may be wirelessly communicated.
