[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is applied to prevent illegal parking or annoying parking in areas where parking is prohibited, such as near fire hydrants and entrances and exits of emergency vehicles, and objects such as automatic transportation lines in factories. The present invention relates to an object abandonment alarm device applied to prevent an object from being left in a no-leave area.

[0002]

[Prior Art]

 In the past, as a means of preventing parking in a no-park area, generally, no-parking signs or standing cards were installed. Moreover, as a more forcible means than this, there are also some means of forcibly prohibiting the entry of vehicles into the no-parking area by using piles, poles, ropes, and the like.

[0003]

[Problems to be solved by the device]

 However, with the conventional means using signs and / or bills, only the fact that the characters are displayed reminds that parking is prohibited.Therefore, there are cases in which illegal parking is performed by overlooking the signs and / or bills. On the other hand, such signs and standing bills alone are not a great warning against malicious drivers. Therefore, drivers often do not know that parking is prohibited and make illegal parking. On the other hand, means using piles or ropes is not preferable because it obstructs the passage of emergency vehicles in an emergency. Further, such a problem similarly occurs when the object is prohibited from being left in a predetermined area such as a traffic line of an automated guided vehicle in a factory production line. Therefore, the object of the present invention is to prevent unlawful parking or object leaving in a prohibited area for parking or forbidden area for objects more effectively than before by means that does not obstruct traffic in an emergency. And

【Example】

 First, an embodiment of a parking alarm device according to the present invention will be described. FIG. 1 is an external perspective view of the parking alarm device A, FIG. 2 is a block diagram showing its hardware configuration, and FIG. 3 is a perspective view of its usage state. The parking alarm device A includes a signal processing unit 3 and various circuits 4 and 5 to be described later in a box 2 made of steel or the like, which is attached to the upper part of a pillar 1 standing upright on the ground. Sensor 6, flash lamp 7, speaker 8 etc. are attached to the front. Of these, an ultrasonic sensor is used as the sensor 6 as an example, and the sensor 6 has a function as a transmitter that intermittently transmits ultrasonic waves of a desired wavelength at regular intervals and receives reflected ultrasonic waves. In addition to its function as a receiver, it also measures the distance from the time the ultrasonic wave is transmitted to the time it is received, or measures the distance to the detected vehicle, and the measured distance is the detected distance. The detection signal of the vehicle is transmitted to the signal processing unit 3 only when the distance is within the range set by the setting switch 9. As the sensor 6, it is possible to use an optical type sensor or an electric wave type sensor other than the ultrasonic type sensor, and in any case, the distance measurement based on the attenuation of the transmitted electric wave or the optical ray is possible. Is possible. In the case of the optical type, it is possible to measure the distance by the triangulation method using a PSD sensor. Further, the sensor 6 is provided so as to be swingable in a horizontal swinging state in the front position of the box 2, or its directivity is set to be weak so that ultrasonic waves can be transmitted at a wide angle. Therefore, it is desirable that the vehicle 18 existing within the range α of the predetermined angle in front of the parking warning device A can be detected.

The signal processing unit 3 receives the vehicle detection signal from the sensor 6, and thereby the flash lamp drive circuit 4 to which the flash lamp 7 is connected and the voice synthesis connected to the speaker 8 via the amplifier 13. The circuit 5 is operated. However, the signal processing unit 3 does not actuate the flash lamp drive circuit 4 and the like immediately upon receiving the detection signal from the sensor 6, but the detection signal from the sensor 6 is set by the reporting time setting switch 12. The flash lamp driving circuit 4 and the voice synthesizing circuit 5 are configured to operate only when the flash lamp is continuously received for a predetermined time or longer. The voice synthesizing circuit 5 is set to synthesize a desired voice message to call out the prohibition of parking. However, the signal processing unit 3 gives an alarm when the continuous detection signal reception time from the sensor 6 is received. The voice synthesizing circuit 5 is controlled so that the message contents of the voice generated from the speaker 8 are different depending on whether the time is within the time set by the content change switch 10 or exceeds the time. That is, if the detection time of the same vehicle by the sensor 6 is within the time set by the alarm content change switch 10, for example, the message "This is a parking prohibited area. Please refrain from parking." , When the time is exceeded, it is configured to say a different message, such as "Parking violation. Please leave the car early". In FIG. 1, the detection distance setting switch 9, the alarm content changing switch 10, the alarm time setting switch 12, and the volume adjusting switch 14 of the amplifier 13 are arranged on the side surface of the box 2 and have a lid with a lock. It is blocked by 15 to prevent mischief. Further, in the figure, 16 is an eaves of the sensor 6 for avoiding rain.

As shown in FIG. 3, the parking alarm device A having the above-described configuration is installed in, for example, one corner of the parking prohibited area M around the fire hydrant 17 or in the vicinity thereof, and the vehicle has entered the parking prohibited area M. 18 is used so that it can be detected by the sensor 6. When the vehicle 18 enters the parking prohibited area M during use, the vehicle 18 is detected by the sensor 6, and the detection signal is immediately transmitted to the signal processing unit 3. It should be noted that the vehicle passing through a position further forward than the parking prohibited area M (for example, the position N) when viewed from the sensor 6 side is also detected by the sensor 6, but in such a case, the distance between the sensor 6 and the vehicle is Since the distance set by the distance setting switch 9 is exceeded, the detection signal is not transmitted from the sensor 6 to the signal processing unit 3. Therefore, the detection signal of the vehicle 18 is transmitted from the sensor 6 to the signal processing unit 3 only when the vehicle 18 enters the parking prohibited area M.

If a time of about 1 minute is set in advance by the alarm time setting switch 12, the signal processing unit 3 immediately causes the flash lamp drive circuit 4 and the voice synthesis in the initial stage when the sensor 6 detects the vehicle 18. It does not activate the circuit 5. In such a case, the alarm will not be issued if the vehicle 18 simply passes through the parking prohibited area M. Next, when the vehicle 18 stops in the parking prohibited area M, the sensor 6 continuously transmits the detection signal of the vehicle 18 to the signal processing unit 3. Therefore, the signal processing unit 3 receives the continuous detection signal at the time (for example, 1 minute) set by the alarm time setting switch 12 when the flash lamp driving circuit 4 and the voice synthesizing circuit are operated. 5 is activated to flash the flash lamp 7, and at the same time, a predetermined warning message such as "This is a parking prohibited area. Please refrain from parking." Is issued from the speaker 8. Therefore, the state of the parking violation is notified to the pedestrians around the vehicle including the driver of the stopped vehicle 18 and the illegal parking is effectively prohibited. Further, nevertheless, when the vehicle 18 is still parked and the continuous transmission time of the vehicle detection signal transmitted to the signal processing unit 3 exceeds the time set by the alarm content change switch 10 (for example, 30 minutes). , This time, the content of the message uttered from the speaker 8 has been changed to a stronger message, such as "Parking violation. Please leave the car early". Therefore, the driver is further urged to immediately leave the vehicle 18. The alarm is stopped when the vehicle 18 leaves the parking prohibited area M and the transmission of the vehicle detection signal from the sensor 6 to the signal processing unit 3 is stopped.

In the above embodiment, the alarm is issued only when the sensor 6 continuously detects the vehicle 18 in the parking prohibited area M for the time set by the alarm time setting switch 12 or longer. However, the present invention according to claim 1 is not limited to this. The sensor 6 may detect the vehicle 18 in the parking prohibited area M and issue the alarm at the same time. In such a case, the alarm will be issued only by the vehicle 18 passing through the parking prohibited area M, but this is preferable from the viewpoint of prohibiting parking. Further, in the above-mentioned embodiment, the sound generation content from the speaker 8 is changed as the parking time of the vehicle 18 is prolonged. However, instead of such means, for example, only the flash lamp 7 blinks at the beginning of parking. In addition, when the parking time exceeds a certain time, a voice alarm from the speaker 8 may be added. However, in the present invention according to claim 1 or 2, it is not always necessary to change the alarm content according to the parking time of the vehicle 18.

4 to 6 show another embodiment of the parking warning device A according to the present invention (however, in the drawings, the same parts as those of the embodiment shown in FIG. 1 are designated by the same reference numerals). In FIG. 4, in place of the flash lamp 7, a rotating lamp 7 a for warning by lighting is attached to the upper surface of the box 2. However, in the present invention according to claims 1 to 3, the specific type of the alarm is not limited. For example, the alarm may be given only by the speaker. 5 and 6 show the case where an optical sensor is used as the sensor 6, and the disturbance light prevention filter 20 mounted on the opening window 19 on the front surface of the box 2 prevents the optical sensor 6 from malfunctioning. It has been prevented.

Next, an embodiment of an object leaving warning device according to the present invention will be described. FIG. 7 shows that the leaving alarm device B is installed at a position where the traveling path (rails 22 1 and 22) of the automatic guided vehicle 21 of the factory intersects with the passage 23, and the object is placed in the leaving prohibited area Ma at the intersection position. It is a perspective view at the time of using for giving an alarm so that it may not be left unattended. The basic configuration of the leaving alarm device B is the same as that of each embodiment of the parking alarm device A, and its hardware configuration is the same as that of FIG. 2, and detects the presence of the object 18a in a desired fixed area. Then, the sensor 6 that transmits the detection signal to the signal processing unit and the flash after a desired time has elapsed by setting the alarm time setting switch 12 when the detection signal is transmitted from the sensor 6 to the signal processing unit 3 The alarm drive circuit 4 and the voice synthesis circuit 5 are activated to give an alarm. However, the voice message synthesized by the voice synthesizing circuit 5 is not a matter concerning the prohibition of parking but a matter concerning the prohibition of leaving the object 18a, and there are other differences such as the mounting height of the sensor 6 being different. Therefore, according to the leaving alarm device B having such a configuration, the object existing in the object leaving prohibited area Ma is surely detected by the sensor 6, and when the object is left standing for a certain time or more, or the leaving prohibited area. When an object is placed on Ma, a predetermined alarm can be issued to call its attention. As with the parking warning device A, the left-behind warning device B according to the present invention can also be modified in design in terms of the specific configuration of each part.

[0013]

As described above, according to the parking alarm device according to the present invention as set forth in claims 1 to 4, even for a driver parked in a predetermined parking prohibited area or a passerby around it. The fact that parking is banned can be notified and the fact that parking is banned can be notified with certainty, which has the effect of helping to eliminate illegal and nuisance parking that could not be eliminated with conventional single signs and standing cards. In addition, unlike the conventional method using ropes and piles, it does not close the prohibited area, so it does not hinder the passage of emergency vehicles. A series of operations can be automated, which is extremely useful. In particular, according to the parking alarm device of the present invention as set forth in claim 2, since the alarm can be issued only when the vehicle is parked in the prohibited area for a certain time or longer, the residential area and the traffic volume can be increased. This has the advantage of eliminating unnecessary notifications in areas with a lot of traffic. Further, according to the parking alarm device of the present invention as set forth in claim 3, as the parking time of the vehicle elapses, it is possible to issue an alarm of appropriate content, so that improper parking is more effectively performed. There is an effect that can be prevented. Further, according to the parking warning device of the present invention as set forth in claim 4, since the warning can be issued by both a visual warning by a flash lamp or a rotating light and a voice message from a speaker, parking is prohibited. There is an advantage that a warning to that effect can be sent without fail. Further, according to the object leaving alarm device according to the present invention as set forth in claim 5, it is possible to issue an alarm when an object is left unreasonably in a predetermined area, thereby eliminating the unjust object release. There is no risk of obstructing the passage of objects into prohibited areas.
