The parking space is a parking space that can be used by persons with disabilities, injured persons, pregnant women, etc. (hereinafter collectively referred to as persons with disabilities), and is a store or a store so that such persons can easily enter and exit the building. It is generally installed near the entrance and exit of buildings of various facilities.

However, in recent years, there have been many cases in which healthy people who should not originally use the parking space park their cars in the parking space. There are various reasons, such as the fact that the parking lot is not available, the parking lot is short, and it is convenient because it is close to the doorway. However, for whatever reason, healthy people are still misusing parking spaces exclusively for people with disabilities.

If a third party discovers such fraudulent use, it may lead to a dispute, and it is difficult to pay direct attention to the fraudulent user. On the other hand, it is effective to prevent unauthorized use by installing a cone or the like in a parking space dedicated to a person with a disability and removing the cone only when the vehicle on which the person with a disability is on board parks. However, in this case, since it is necessary to keep personnel resident in the parking lot in order to confirm the passengers and move the cone, there is a limit to the personnel cost and the response speed.

In view of this situation, various technologies have been developed to prevent unauthorized use of parking spaces dedicated to persons with disabilities. For example, Patent Document 1 describes a parking sign installed in a parking lot, which collapses when a signal from a remote controller that only a physically handicapped person is allowed to possess is received, and makes the parking lot available for parking. The technology is disclosed. Further, Patent Document 2 discloses a technique of raising the gate to enable parking when an infrared irradiation key possessed by a person with a disability is held over a parking device. Further, in Patent Document 3, the fixed communication device of the equipment dedicated to the disabled receives the information from the non-contact IC card containing the information proving that the person is a disabled person via the mobile communication device. In some cases, a system that makes the equipment available is disclosed. Further, Patent Document 4 discloses a system that receives authentication information from a vehicle and enables parking in a parking lot when the authentication information is registered as a vehicle for a person with a disability.

It is a unit to show that it is dedicated. A parking space exclusively for persons with disabilities is a parking space generally provided near the entrance / exit of a store or various facilities, and is a parking space that can be used by persons with disabilities. The parking space may be available to injured persons, sick persons, pregnant women, etc. in addition to persons with disabilities.

The parking guidance unit 1 is, for example, a signboard-shaped self-propelled device including a sign for a parking lot exclusively for persons with disabilities. The parking guidance unit 1 is a unit capable of preventing unauthorized use of the parking space of a healthy person.

FIG. 1A shows an example of a parking space in which the parking guidance unit 1 is installed. As shown in the figure, the parking guidance unit 1 is usually installed near the center of the parking space so as to prevent parking.

FIG. 1B shows an operation example of the parking guidance unit 1 when a vehicle enters the parking space. When a vehicle enters the parking space, the parking guidance unit 1 starts outputting at least one of light and voice. For example, the parking guidance unit 1 turns on (or blinks) a lamp and outputs a sound. As shown in the balloon in the figure, it is desirable that the voice is a voice notifying that the parking space in which the parking guidance unit 1 is installed is a parking space exclusively for persons with disabilities.

When the parking guidance unit 1 outputs at least one of light and voice, the attention of the surrounding people is directed to the parking space and the parking guidance unit 1. If the passenger of the vehicle is a person who is not qualified to park in the parking space (that is, a healthy person), and the people around him are paying attention to the parking space in this way, hesitate to park in an eye-catching manner. Probability is high. Therefore, the parking guidance unit 1 can voluntarily stop the parking of a healthy person in the parking space.

Further, when the passenger of the vehicle is a healthy person, by making the parking guidance unit 1 stand out in this way, it is possible to emphasize to the passenger that the parking space is exclusively for the person with a disability. As a result, it is possible to appeal to the conscience of the passenger, and it is possible to prevent unauthorized use of the parking space by a healthy person.

Further, as shown in FIG. 1B, when the parking guidance unit 1 detects the intrusion of a vehicle into the parking space, the parking guidance unit 1 moves the parking guidance unit 1 so that the parking space can be parked. At this time, the parking guidance unit 1 does not move immediately after detecting the intrusion of the vehicle, but moves the parking guidance unit 1 after a certain period of time or over time. As a result, the parking guidance unit 1 can be kept in the state of attention as described above. In addition, it is possible to prevent unauthorized use due to reasons such as not wanting to park in a parking lot far from the store or facility because it is in a hurry, or not being able to wait for the parking lot to become available.

FIG. 1C shows an example of a parking space in a state where the vehicle is stopped. When the movement of the parking guidance unit 1 shown in FIG. 1B is completed, the parking space becomes ready for parking. In this state, the vehicle can be parked by entering the depth of the parking space as shown in the figure.

§2 Configuration example (appearance of parking guidance unit)
FIG. 2 is a view showing the front appearance of the parking guidance unit 1. Here, the "front" indicates a surface of each surface of the parking guidance unit 1 facing the vehicle to be parked in the parking space.

The parking guidance unit 1 further includes a position detection sensor 20, a camera 30, a speaker 40, and a lamp 50. The position detection sensor 20 is a sensor for the parking guidance unit 1 to measure the current position of its own device. The camera 30 captures at least a part of the parking space as a still image or a moving image. The shooting angle and shooting interval of the camera 30 are not particularly limited as long as the shooting angle and shooting interval can be detected by the vehicle detection unit 11 described later from the shot image of the camera 30. The speaker 40 outputs sound. The lamp 50 is a lamp that lights up or blinks.

The size, shape, number, and placement position of the speaker 40 are not particularly limited as long as the speaker 40 can output sound with an output that can be heard by the passengers of the vehicle and those around the parking space. Further, the number, color, brightness, and arrangement position of the lamp 50 are not particularly limited as long as the lamp 50 is lit so as to be visible to the passengers of the vehicle and those around the parking space. The speaker 40 and the lamp 50 may be arranged on the back surface or the side surface.

Although it is not a component of the parking guidance unit 1, it is desirable that the tire stopper B in the parking space is arranged with a width that allows the tire 70 to pass through, as shown in the figure. As a result, the parking guidance unit 1 can travel in the rear direction and turn to the rear side of the tire stopper B. This makes it possible to prevent the vehicle from coming into contact with or colliding with the parking guidance unit 1 when parking.

(Main part configuration of parking guidance unit)
FIG. 3 is a block diagram showing a main configuration of the parking guidance unit 1. In addition to the position detection sensor (sensor) 20, camera 30, speaker (output unit) 40, lamp (output unit) 50, and tire 70 described above, the parking guidance unit 1 includes a control unit (control device) 10, a motor 60, and The battery 80 is provided inside.

The motor 60 is a motor that operates the tire 70 according to the control of the motor control unit 15 described later. The battery 80 supplies power to the entire parking guidance unit 1. The type of the battery 80 is not particularly limited, but may be, for example, a solar cell, a storage battery, or the like. Alternatively, when the parking guidance unit 1 and the power supply (outlet) of the store or facility are close to each other, the parking guidance unit 1 may be connected to the power supply of the store or facility with an electric wire to secure the power supply. Further, when the battery 80 is various batteries, the parking guidance unit 1 may be provided with a charging lamp or the like indicating that the remaining battery level is equal to or less than a predetermined value.

The control unit 10 comprehensively manages the parking guidance unit 1. More specifically, the control unit 10 includes a vehicle detection unit 11, a timer 12, a voice output control unit (output control unit) 13, a lamp control unit (output control unit) 14, and a motor control unit (motion control unit). Including 15.

The vehicle detection unit 11 detects the intrusion of the vehicle into the parking space based on the image captured by the camera 30. For example, the vehicle detection unit 11 determines whether or not a moving object having a size larger than a certain level is captured in the captured image (moving image or a plurality of still images) of the camera 30. When the moving object is captured, the vehicle detection unit 11 determines that the vehicle has entered the parking space, and notifies the timer 12 that the vehicle has been detected.

Further, when the moving object is no longer captured in the image captured by the camera 30, the vehicle detection unit 11 determines that the vehicle has left the parking space and notifies the timer 12 that the vehicle has left.

In addition, the vehicle detection unit 11 detects the completion of parking of the vehicle. For example, when the vehicle detection unit 11 identifies that the vehicle has stopped at a predetermined position in the parking space (the moving object has stopped moving) based on the image captured by the camera 30, the parking of the vehicle is completed. Is determined. The vehicle detection unit 11 may notify the voice output control unit 13 and the lamp control unit 14 of the completion of parking of the vehicle.

The vehicle detection unit 11 takes a difference between the image of the parking space that is not parked and the image taken by the camera 30, and analyzes the difference to indicate that the vehicle has entered, that the vehicle has left, and that the vehicle has left. It may be specified that the vehicle has been parked.

The vehicle detection unit 11 is not a captured image of the camera 30, but a sensor output (output from the sensor) of the position detection sensor 20 or another sensor (infrared sensor, ultrasonic sensor, etc.) provided in the parking guidance unit 1 (not shown). Based on the values or data provided), the intrusion of the vehicle, the departure of the vehicle, and the completion of parking of the vehicle may be detected. Further, one or more loop coils for detecting the metal part of the vehicle are embedded in the ground of the parking space, and the vehicle detection unit 11 intrudes the vehicle, leaves the vehicle, and the vehicle based on the sensor output of the loop coil. You may detect the completion of parking. When the detection is performed using the input from these sensors or the loop coil, the parking guidance unit 1 does not have to include the camera 30.

The timer 12 manages the time from the entry of the vehicle into the parking space to the start of driving of the motor 60 by the motor control unit 15. When the timer 12 is notified by the vehicle detection unit 11 that the vehicle has invaded, the timer 12 starts time measurement, and when a predetermined time (second predetermined time) elapses, the voice output control unit 13 and the lamp control unit 14 and the motor control unit 15 are instructed to start control. When the vehicle detection unit 11 receives a notification that the vehicle has left during the time measurement, the timer 12 stops the time measurement.

As a result, the movement of the parking guidance unit 1 is started only when the vehicle stays in the parking space for a second predetermined time or longer. Therefore, it is possible to prevent the vehicle from erroneously reacting to the vehicle entering the parking space due to temporary turning back or the like to output light and voice and move the parking guidance unit 1.

Further, when the notification that the vehicle has left is received from the vehicle detection unit 11 when the time is not measured, the timer 12 causes the vehicle to be sent to the voice output control unit 13, the lamp control unit 14, and the motor control unit 15. Notify you that you have left.

The motor control unit 15 controls the drive of the motor 60. When the timer 12 instructs the motor control unit 15 to start control, the motor control unit 15 drives the motor 60. At this time, the motor control unit 15 drives the motor 60 so that the vehicle can be parked in the parking space while confirming the position of the parking guidance unit 1 based on the sensor output of the position detection sensor 20.

Further, the motor control unit 15 takes a first predetermined time after the vehicle detection unit 11 detects the intrusion of the vehicle (that is, from the start of measurement of the timer 12) so that the movement of the parking guidance unit 1 is completed. In addition, the rotation speed of the motor 60 and the like are adjusted. It is desirable that the first predetermined time is set to a time such as 10 seconds or the like in which the vehicle is temporarily stopped and the passengers are kept on standby to some extent. By providing the waiting time in this way, when the passenger of the vehicle is a healthy person, it is possible to reconsider the unauthorized use of the parking space.

In addition, by allowing a certain amount of time to park, it is possible to prevent unauthorized use due to reasons such as being in a hurry and not wanting to park in a parking lot far from the store or facility, or waiting for the parking lot to become available. can do.

Further, the motor control unit 15 drives the motor 60 when the timer 12 notifies that the vehicle has left, and moves the parking guidance unit 1 to a position where the parking space cannot be parked. For example, the motor control unit 15 moves the parking guidance unit 1 to the vicinity of the center of the parking space while confirming the position of the parking guidance unit 1 based on the sensor output of the position detection sensor 20. As a result, the parking guidance unit 1 is installed near the center of the parking space when it is not parked.

The audio output control unit 13 controls the audio output from the speaker 40. When the timer 12 instructs the start of control, the voice output control unit 13 outputs voice from the speaker 40. The output voice at this time is preferably a voice notifying that the parking space is a parking space exclusively for persons with disabilities. In addition, the output voice includes a voice notifying that the vehicle that has entered the parking space is recorded, a voice notifying that the use of the parking space of a healthy person is prohibited, and a parking space such as a usage certificate. It may contain one or more of the voices prompting you to confirm that you have the goods necessary for the use of.

The voice output control unit 13 may repeatedly output voice data of a predetermined length from the speaker 40 at regular time intervals (for example, every 5 minutes). Further, the audio output control unit 13 may reproduce and output audio data having a predetermined length only once. Further, the voice output control unit 13 may continue to output voice until the vehicle detection unit 11 notifies that the parking of the vehicle is completed.

Further, the voice output control unit 13 may continue to output voice from the speaker 40 from the time when the vehicle detection unit 11 detects the intrusion of the vehicle until the movement of the parking guidance unit 1 is completed. The vehicle and passengers will stand by in the parking space until the movement of the parking guidance unit 1 is completed. By outputting the sound including the above contents from the speaker 40 during the standby state, when the vehicle is a healthy person's vehicle, the healthy person can be psychologically pressured against unauthorized use of the parking space. .. This makes it possible for healthy people to hesitate to park and to stop unauthorized use by themselves.

Further, if the voice output control unit 13 is outputting voice from the speaker 40 when the timer 12 notifies that the vehicle has left, the voice output control unit 13 ends the voice output.

The lamp control unit 14 controls lighting and extinguishing of the lamp 50. When the timer 12 instructs the lamp control unit 14 to start control, the lamp control unit 14 lights or blinks the lamp 50. The lamp 50 may turn on or blink the lamp 50 for a predetermined time. Further, the lamp control unit 14 may continue to turn on or blink the lamp 50 until the vehicle detection unit 11 notifies that the parking of the vehicle is completed.

Further, the lamp control unit 14 may continue to light or blink the lamp 50 from the time when the vehicle detection unit 11 detects the intrusion of the vehicle until the movement of the parking guidance unit 1 is completed. When the lamp 50 lights up or blinks while the vehicle and the passenger are on standby, the parking space, and thus the vehicle on standby in the parking space, becomes conspicuous from the surroundings. When the vehicle is a vehicle of a healthy person, the healthy person is exposed to the eyes of the surroundings while waiting, and therefore feels psychological pressure against the unauthorized use of the parking space. Therefore, by turning on or blinking the lamp 50, it is possible to make a healthy person hesitate to park and stop the unauthorized use by himself / herself.

Further, the lamp control unit 14 turns off the lamp 50 when the timer 12 notifies that the vehicle has left the lamp 50 and the lamp 50 is lit or blinking.

The parking guidance unit 1 may be provided with only one of the speaker 40 and the lamp 50. When the speaker 40 is not provided, the control unit 10 does not have to include the audio output control unit 13. Further, when the lamp 50 is not provided, the lamp control unit 14 may not be included in the control unit 10.

Further, the timer 12 may notify only the voice output control unit 13 and the lamp control unit 14 of the control start command. Then, the voice output control unit 13 and the lamp control unit 14 may instruct the motor control unit 15 to start control when the output to the speaker 40 and the lamp 50 is completed. As a result, the vehicle is first guided by light and voice, and then the parking guidance unit 1 is started to move. By making it possible to park in a two-step procedure in this way, it is possible to dare to take time to park in the parking space. As a result, it is possible to prevent unauthorized use of the parking space for the purpose of parking in a hurry.

Moreover, the time measurement by the timer 12 is not indispensable. When the control unit 10 does not include the timer 12, the vehicle detection unit 11 directly notifies the voice output control unit 13, the lamp control unit 14, and the motor control unit 15 of various detection results.

(Processing flow)
FIG. 4 is a flowchart showing an example of the processing flow in the parking guidance unit 1. The parking guidance unit 1 is installed near the center of the parking space. When a vehicle invades the parking space more than a certain amount, the vehicle detection unit 11 detects the intrusion of the vehicle based on the image captured by the camera 30 (S10, vehicle detection step) and notifies the timer 12. The timer 12 starts time measurement. After that, when the second predetermined time elapses without detecting that the vehicle has left the parking space, that is, when the vehicle stays in the parking space for the second predetermined time or more ( YES in S12), the timer 12 instructs the voice output control unit 13, the lamp control unit 14, and the motor control unit 15 to start control. If the vehicle leaves the parking space before the second predetermined time elapses (NO in S12), the subsequent processing is not executed.

Upon receiving the control start instruction from the timer 12, the voice output control unit 13 starts voice output, and the lamp control unit 14 lights or blinks the lamp 50 (S14, output control step). Upon receiving the control start instruction from the timer 12, the motor control unit 15 drives the motor 60 to move the parking guidance unit 1 so that the parking space can be parked (S16, operation control step). Note that S16 may be performed in parallel with S14. When the movement of the parking guidance unit 1 is completed, the voice output control unit 13 ends the voice output, and the lamp control unit 14 turns off the lamp 50 (S18). As described above, the output times of the speaker 40 and the lamp 50 may be before the timing of S18.

When the parking guidance unit 1 outputs light and sound, the attention of the surrounding people is directed to the parking space and the parking guidance unit 1. When the passenger of the vehicle is a healthy person, if the people around him pay attention to the parking space in this way, he / she is likely to hesitate to park because he / she is concerned about the eyes. Therefore, the parking guidance unit 1 can voluntarily stop the parking of a healthy person in the parking space.

Further, when the passenger of the vehicle is a healthy person, by making the parking guidance unit 1 stand out in this way, it is possible to emphasize to the passenger that the parking space is exclusively for the person with a disability. As a result, it is possible to appeal to the conscience of the passenger, and it is possible to prevent unauthorized use of the parking space by a healthy person.

Furthermore, there is no burden on persons with disabilities to perform these processes. This is because people with disabilities can use the parking space legitimately, and even if the parking space stands out from the surroundings as described above, even if voice guidance is given about the right to use the parking space, there is no psychological pressure. Therefore, according to the above processing, it is possible to prevent unauthorized use of the parking space without imposing a burden on the person with a disability.

Person H in the figure is a passenger of a vehicle parked in the parking space in the center of the figure. As shown in FIGS. 5A to 5B, when the person H approaches the vehicle by a predetermined distance or less, the parking guidance unit 2 detects the approach of the person H and outputs a sound from the speaker 40. The sound output here may be the same as the sound played when the vehicle is parked, or may include different contents. Further, the parking guidance unit 2 lights or blinks the lamp 50.

As a result, the person H who has returned to the vehicle and the vehicle stand out from the surroundings. Therefore, when the person H is a healthy person, it is clearly shown by the surroundings that he / she is misusing. By applying psychological pressure to the person H at the time of boarding in this way, if the person H is an unauthorized user, he / she can hesitate to use the parking space from the next time. Therefore, it is possible to reduce the unauthorized use of the parking space.

Then, when the vehicle leaves the parking space as shown in FIG. 5 (c), the parking guidance unit 2 detects that the vehicle has left. Then, as shown in FIG. 5D, the parking guidance unit 2 moves its own device to a position where the parking space cannot be parked. The parking guidance unit 2 will be located near the center of the parking space, for example, until the next vehicle enters the parking space.

(Main part composition)
FIG. 6 is a block diagram showing a main configuration of the parking guidance unit 2 according to the present embodiment. The parking guidance unit 2 is different from the parking guidance unit 1 in that it includes a person detection unit 16. The person detection unit 16 detects the approach of a person to a parked vehicle based on the captured image of the camera 30 or the sensor output of the position detection sensor 20. The person detection unit 16 notifies the voice output control unit 13 and the lamp control unit 14 that the approach of a person has been detected. The person detection unit 16 may detect the approach of a person based on the sensor output of another sensor (infrared sensor, ultrasonic sensor, etc.) provided in the parking guidance unit 2 (not shown).

Upon receiving the notification, the voice output control unit 13 causes the speaker 40 to output voice. Further, when the lamp control unit 14 receives the notification, the lamp 50 is turned on or blinks. The audio output and the lighting time or blinking time of the lamp 50 are not particularly limited. For example, the voice output control unit 13 and the lamp control unit 14 may continue to output until the vehicle detection unit 11 notifies that the vehicle has left the parking space.

(Processing flow)
FIG. 7 is a flowchart showing an example of the processing flow in the parking guidance unit 2. When a person approaches a parked vehicle while the vehicle is parked in the parking space, the captured image of the camera 30 or the sensor output of the position detection sensor 20 changes. The person detection unit 16 detects the approach of a person based on the captured image or the sensor output (S20). The person detection unit 16 notifies the voice output control unit 13 and the lamp control unit 14 of the approach of a person. The voice output control unit 13 starts the voice output of the speaker 40, and the lamp control unit 14 lights or blinks the lamp 50 (S22). These outputs may be continued while the parked vehicle is in the parking space (NO in S24).

When a person gets into the parked vehicle, the vehicle starts and exits the parking space (YES in S24), the vehicle detection unit 11 detects that the vehicle has left and notifies the timer 12 of this. The timer 12 does not measure the time, and notifies the voice output control unit 13, the lamp control unit 14, and the motor control unit 15 that the vehicle has left. The voice output control unit 13 ends the voice output when the notification is received, and the lamp control unit 14 turns off the lamp 50 when the notification is received (S26). Further, the motor control unit 15 operates the motor 60 to move the parking guidance unit 2 so that the parking space cannot be parked (S28). The order of S26 and S28 does not matter.

According to the above processing, when a person returns to the parked vehicle, the person and the vehicle can be made to stand out from the surroundings. Therefore, if the person who returned is a healthy person, it is clearly shown to the surroundings that he / she is misusing. Therefore, psychological pressure can be applied to an unauthorized user of the parking space. This makes it possible to hesitate to use the parking space from the next time. Therefore, it is possible to reduce the unauthorized use of the parking space.

The parking guidance unit 2 may detect that the door of the vehicle has been opened by the vehicle detection unit 11 instead of detecting the person by the person detection unit 16. The fact that the door was opened is because it is clear that there are people nearby. The method of detecting that the door has been opened is not particularly limited, but a moving object having a size equivalent to that of the door is detected in the image taken by the camera 30 (the image taken while parking) as in the case of approach detection of a vehicle. At that time, it may be determined that the door has been opened.

[Embodiment 3]
The control unit 10 of the parking guidance unit 1 or 2 may include an input reception unit that receives input from a predetermined input device. Then, when the input receiving unit receives the input, the motor control unit 15 moves the parking guidance unit 1 or 2 so that the vehicle can be parked in the parking space in a shorter time than the first predetermined time. May be good.

For example, the configuration and processing described below are possible. First of all, a remote controller (input device) that can be operated by a store clerk is prepared together with the parking guidance unit 1 or 2. The parking guidance unit 1 or 2 receives the input from the remote controller at the input reception unit. This remote controller can be used, for example, for an emergency vehicle such as an ambulance, a fire engine, or a police car to park in a parking space in an emergency.

In an emergency, when a clerk performs a predetermined operation (for example, pressing a button instructing to move a specific parking guidance unit 1 or 2) with the remote controller, the remote controller gives an instruction corresponding to the operation to the parking guidance unit 1 or Send to 2. Upon receiving the instruction (input), the input receiving unit of the parking guidance unit 1 or 2 instructs the motor control unit 15 to control the motor 60.

The motor control unit 15 moves the parking guidance unit 1 or 2 by operating the motor 60 to make the parking space parkable. Here, the motor control unit 15 adjusts the rotation speed of the motor 60 and the like so that the parking guidance unit 1 or 2 moves faster than at least the first predetermined time. More preferably, the motor control unit 15 controls the motor 60 so that the parking guidance unit 1 or 2 moves as fast as possible. Thereby, in an emergency, the parking guidance unit 1 or 2 can be quickly moved according to the operation input of a person. Therefore, in an emergency, the parking space can be quickly vacated for the emergency vehicle.

The control unit 10 may be able to switch to a mode in which the own device is manually operated (manual mode). For example, the parking guidance unit 1 or 2 is provided with a physical switch for turning on the manual mode, the input receiving unit detects that the physical switch is turned on, and the control unit 10 puts its own device in the manual mode. You may switch to. Further, the parking guidance unit 1 or 2 is provided with an input panel or the like for inputting a password code, and the control unit 10 receives input of a predetermined password code from the input reception unit when the input reception unit receives the input of the password code. You may switch your device to manual mode. Further, the control unit 10 may switch its own device to the manual mode when the input reception unit receives the input of the password code from the remote controller described above.

The specific usage scene of the manual mode will be described below. Store or facility personnel can put parking guidance unit 1 or 2 into manual mode by unlocking parking guidance unit 1 or 2 and turning on the physical switch (or entering the password code with the remote control). Switch. Then, the parking space can be parked by operating the parking guidance unit 1 or 2 manually or by operating the remote controller. In this way, by using the manual mode, the parking guidance unit 1 or 2 can be freely moved according to the judgment of the persons concerned. For example, in an emergency or when it is desired to move the parking guidance unit 1 or 2 to another parking space, the parking guidance unit 1 or 2 can be easily moved by using the manual mode.

It is desirable that the physical switch is normally locked so that it cannot be operated unless it is unlocked with a key possessed by a person concerned with the store or facility (hereinafter, simply referred to as a person concerned). In addition, it is desirable that the password code be managed so that only the persons concerned can know it. This is to prevent general users, who are not related parties, from switching to the manual mode.

[Embodiment 4]
The position detection sensor 20 or the camera 30 of the parking guidance unit 1 according to each of the above embodiments may be an external device of the parking guidance unit 1. Further, the parking guidance unit 1 may not be controlled by the control unit 10 built in the parking guidance unit 1, but may be centrally controlled by a personal computer (PC) or the like. 8 (a) and 8 (b) are views showing a modified example of the parking guidance unit.

FIG. 8A shows a parking guidance unit 3 provided with a camera 30 as an external device. The configuration of the parking guidance unit 3 is the same as that of the parking guidance unit 1 except that the camera 30 is eliminated and a communication unit that communicates with the camera 30 is provided instead. In this way, by providing the camera 30 as an external device and receiving the photographed image from the camera 30, the photographing angle of the camera 30 can be made constant regardless of the position of the parking guidance unit 3. Therefore, the vehicle detection unit 11 can detect the vehicle more accurately.

When the position detection sensor 20 is used as an external device, it is substantially the same as the case of FIG. 8A. By configuring the parking guidance unit to include a communication unit that eliminates the position detection sensor 20 and communicates with the position detection sensor 20, the detection accuracy of the position detection sensor 20 is improved. For example, when the position detection sensor 20 is a camera, a distance measurement sensor, or the like, the position of the position detection sensor 20 itself is fixed, so that it is not necessary to correct the output result of the sensor with the current position of the parking guidance unit.

FIG. 8B shows a parking guidance unit 4 having a communication unit that eliminates the control unit 10 and instead communicates with the PC 5, and has a function of the control unit 10 and communicates with a plurality of parking guidance units 4. It is a figure which shows the outline of the parking guidance system including PC5. The PC 5 receives the sensor output of the position detection sensor 20 of each unit and the captured image of the camera 30 from one or more parking guidance units 4, and executes various control processes similar to those of the control unit 10. Then, the PC 5 transmits various control commands (voice output, lamp lighting or blinking, motor drive, and other control commands) to the parking guidance unit 4 that has transmitted the sensor output and the captured image.

In this way, by configuring the plurality of parking guidance units 4 to be centrally managed by one PC 5, it is not necessary to incorporate the control unit 10 for each parking guidance unit 4, so that the production cost of the parking guidance unit 4 is reduced. be able to. Further, the control unit 10 is a member that is more likely to break down due to an impact, a high temperature, or the like, as compared with a relatively strong hardware member. Therefore, the failure rate of the parking guidance unit 4 can be reduced by not providing the control unit 10 in the parking guidance unit 4 which is often installed outdoors such as in a parking lot.

[Modification example]
In the above description, the parking guidance units 1 to 4 are signboard-type self-propelled devices. However, the shapes of the parking guidance units 1 to 4 and the method of operation are not limited to this. For example, the parking guidance units 1 to 4 may include a gate portion, and the bar at the gate portion may be opened / closed or moved up / down to control whether or not parking in the parking space is possible. In this case, the motor control unit 15 operates the motor 60 to open / close or raise / lower the bar at the gate portion of the parking guidance units 1 to 4.

Further, for example, the parking guidance units 1 to 4 may include a roll-up type curtain portion, and the parking possibility in the parking space may be controlled by winding up or lowering the curtain. In this case, the motor control unit 15 operates the motor 60 to wind up or lower the curtain portion of the parking guidance units 1 to 4.

Further, for example, the parking guidance units 1 to 4 may be of a flap type. In this case, the motor control unit 15 operates the motor 60 to fold the own device substantially parallel to the ground to enable parking of the parking space, or to raise the own device from the ground to prevent parking of the parking space. It can be made possible.

In addition, the parking guidance units 1 to 4 may be moved by rails instead of the tires 70, or are a part of a parking guidance unit that stores the vehicle in the basement when the vehicle is parked. May be good.

[Example of realization by software]
The control block of the control unit 10 may be realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or may be realized by software.

In the latter case, the control unit 10 includes a computer that executes instructions of a program that is software that realizes each function. The computer includes, for example, one or more processors and a computer-readable recording medium that stores the program. Then, in the computer, the object of the present invention is achieved by the processor reading the program from the recording medium and executing the program. As the processor, for example, a CPU (Central Processing Unit) can be used. As the recording medium, a "non-temporary tangible medium", for example, a ROM (Read Only Memory) or the like, a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like can be used. Further, a RAM (Random Access Memory) for expanding the program may be further provided. Further, the program may be supplied to the computer via an arbitrary transmission medium (communication network, broadcast wave, etc.) capable of transmitting the program. It should be noted that one aspect of the present invention can also be realized in the form of a data signal embedded in a carrier wave, in which the program is embodied by electronic transmission.
