DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
FIG. 1 is a block diagram showing the configuration of a monitoring warning system according to the first embodiment of the present invention. In FIG. 1, a determination processing means 2 for measuring one or a plurality of traveling vehicles 1 (monitoring target) traveling on a road includes a speed radar 3, a sound level meter 4, an image recognition device 5 having an imaging device 5A, infrared measurement. One or more devices among the devices 6 are connected. The determination processing means 2 transmits a determination information signal G to the warning means 7 based on the determination of these devices.
[0008]
The speed radar 3 emits ultrasonic waves or electromagnetic waves in the direction A (the direction of the traveling vehicle 1) from the emitting portion of the radar 3A directed toward the traveling vehicle 1, and the reflected signal B reflected from the traveling vehicle 1 is transmitted to the radar 3A. It has a function of determining whether or not the traveling speed of the traveling vehicle 1 is not a super high speed or a super low speed but within a predetermined travel speed range by detecting and calculating the reception portion. Further, the sound level meter 4 collects sound C generated when the traveling vehicle 1 travels with a microphone 4A directed to the traveling vehicle 1, and the traveling vehicle 1 determines whether the traveling vehicle 1 has a predetermined value based on an electric signal obtained by converting the magnitude of the sound. It has a function to judge whether or not noise exceeding the level is emitted. Next, the image recognition device 5 processes the image data obtained by capturing the image D included in the signal from the imaging device 5A such as a CCD camera facing the direction of the traveling vehicle 1, and when the shape is captured in the image or the like. For example, the trajectory of the traveling vehicle 1 is determined from the change of the series, and a function is provided for determining whether or not the traveling vehicle 1 is performing dangerous actions such as meandering and collecting. Furthermore, the infrared measuring device 6 is emitted from the vehicle body including the engine of the traveling vehicle 1 and is based on the amount (temperature level) of infrared E converted into an electrical signal by the infrared sensor 6A, for example. 1 has an infrared measurement function for determining whether or not dangerous actions such as meandering or collecting are performed. Here, the infrared wavelength band detected by the infrared sensor 6A is a 3 to 5 μm band that can be easily identified as a wavelength band close to visible light, or an 8 to 12 μm band that is easy to detect even with a long distance or an infrared radiation amount with a small heating element. I will decide. The determination of the dangerous act by the infrared measuring device 6 may be performed independently, but it is better to link the determination with the speed radar 3, the sound level meter 4, and the image recognition device 5 as an auxiliary.
[0009]
The parametric speaker 8 serving as the sound warning means 7 is a device that generates an audible band sound having superdirectivity using an ultrasonic sound signal of 20 kHz or higher as a carrier. Although the parametric speaker 8 has low conversion efficiency for obtaining audible band sound, it can be used as a superdirective speaker because the audible band sound can be concentrated in a beam shape in a narrow area. When the parametric speaker 8 receives the determination information signal G transmitted from the determination processing means 2, the sound signal F becomes a warning sound (including sound) so that it can be heard only by the driver of the traveling vehicle 1 performing the dangerous act. To emit.
[0010]
Next, the operation of this system will be described. Based on the determination from any one of the speed radar 3, the sound level meter 4, the image recognition device 5, and the infrared measurement device 6, the traveling vehicle 1 performs a dangerous act such as an overspeeding action, a noise excessing action, and a meandering action. The determination processing means 2 transmits a determination information signal G to the parametric speaker 8. Here, a criterion for transmitting the determination information signal G by the determination processing means 2 is that transmission is not performed unless determination is made that all devices are regarded as dangerous acts (such as when the speed radar 3 determines excessive speed). Various criteria can be set, such as transmission if it is determined that even one device is regarded as a dangerous act.
[0011]
The parametric loudspeaker 8 that has received the determination information signal G is directed to the traveling vehicle 1 that is performing a dangerous act. For example, an audio signal that indicates “stop the dangerous act immediately and leave this road” to prompt the stop of the act. Issue F. If the signal of the determination information G from the determination processing means 2 is received again after a certain time, the parametric speaker 8 sounds a warning sound (for example, a siren, a sound disliked by a person, etc.) prompting the withdrawal of the traveling vehicle 1. The signal F is further emitted.
[0012]
As described above, according to the first embodiment, the determination processing means 2 to which one or a plurality of devices among the speed radar 3, the sound level meter 4, the image recognition device 5, and the temperature detection device 6 are connected. If it is determined that the traveling vehicle 1 is performing an illegal action based on a physical quantity or the like measured by the apparatus of FIG. 1, the determination information signal G is transmitted, and the superdirective parametric speaker 8 that has received the determination information signal G receives the illegal action. Since the warning sound is emitted only to the traveling vehicle 1 performing the operation, the target sound can be heard without causing trouble to the surroundings.
[0013]
Embodiment 2. FIG.
FIG. 2 is a block diagram showing the configuration of the monitoring warning system according to the second embodiment of the present invention. In FIG. 2, the same reference numerals as those in FIG. 1 perform the same operations as those described in the first embodiment, and thus description thereof is omitted. In this embodiment, the radio signal generation means 9 is a means that constitutes the warning means 7 together with the parametric speaker 8. The radio wave signal generating means 9 generates a radio wave signal H that is an electromagnetic wave that stops the dangerous action of the traveling vehicle 1, for example, is controlled so as to reduce to a slow speed. Therefore, the radio wave signal H is not radioactive but has directivity so that it is received only by the target vehicle.
[0014]
Next, the operation of the system of this embodiment will be described. Since operations similar to those of the first embodiment are performed until the warning by the sound signal F is performed by the warning sound, the description thereof is omitted. The determination processing means 2 is one of the speed radar 3, the sound level meter 4, the image recognition device 5, and the infrared measurement device 6 even after a predetermined time after transmitting the determination information signal G to the parametric speaker 8 and generating a warning sound. If it is determined that the traveling vehicle 1 is performing a dangerous act based on the determination from the device, the determination information signal G is transmitted to the radio signal generation means 9. Here, the criterion for transmitting the determination information signal G by the determination processing means 2 may be the same as that when the determination information signal G is transmitted to the parametric speaker 8 or may be a different criterion.
[0015]
The radio signal generating means 9 that has received the determination information signal G issues a radio signal H for stopping the action toward the traveling vehicle 1 that is performing the dangerous action. When the traveling vehicle 1 receives the radio wave signal H, for example, a warning is displayed on a display device mounted in the car navigation system. In addition, for example, by stopping the function of the electronic components mounted on the traveling vehicle 1, the traveling vehicle 1 is driven slowly or stopped in some cases.
[0016]
As described above, according to the second embodiment, since the radio signal H is generated based on the radio signal generation means 9, the traveling vehicle 1 that does not attempt to stop the dangerous act only with a warning sound or the like. The radio wave signal H can be used to display or act on the vehicle, which can further increase the possibility of stopping the dangerous action as compared with the conventional monitoring method.
[0017]
Embodiment 3 FIG.
In the second embodiment described above, if both the parametric speaker 8 and the radio signal generation means 9 are provided, and the traveling vehicle 1 is performing a dangerous act after a certain time has elapsed since the warning sound from the parametric speaker 8 was emitted, the second embodiment again. When it is recognized, the determination information signal G is transmitted to the radio wave signal generating means 9 to transmit the electromagnetic wave pulse H. However, the present invention is not limited to this, and only the radio signal generation means 9 may be provided, and the determination information signal G may be transmitted to the radio signal generation means 9.
[0018]
Embodiment 4 FIG.
In the above-described embodiment, the traveling vehicle is monitored, and when it is determined that a dangerous act is being performed, a warning sound (sound) is emitted using the parametric speaker 8. The present invention is not limited to this. For example, for a person who installs a parametric speaker 8 at an exit in a store and tries to leave the store without paying the price, only that person You can be warned to hear and ask for payment. Moreover, the parametric speaker 8 and the radio signal generation means 9 are installed in a garbage collection place, and can be used for repelling crows and the like that damage garbage. The method of the present invention can be realized by a speaker having directivity that does not affect the surroundings.
[0019]
【The invention's effect】
As described above, according to the present invention, when the determination information signal is transmitted from the detection unit that transmits the determination information signal when it is determined that the monitoring target is performing the warning target action, the sound warning unit having directivity is provided. Since a warning sound is emitted to the monitoring target using an audio signal of 20 kHz or higher as a carrier wave, the target sound can be heard without causing trouble to the surroundings. Further, depending on the sound to be emitted, it is also possible to stop the action to be warned.
In addition, when it is determined again after a certain time that the monitored object is performing an action subject to warning, a signal generated by electromagnetic waves is emitted by the radio wave transmission means, so that the traveling vehicle does not attempt to stop the dangerous action only with a warning sound or the like. In contrast, it is possible to display or act on the vehicle, thereby further increasing the possibility of stopping the dangerous act.
