Description

[Technical Field]

[0001] The present invention relates to a guidance device and a guidance system for guiding users (vehicles and people) so that they can move safely and conveniently within a parking lot or the like. [Background technology]

[0002] A device has been proposed to guide users who intend to use a parking lot so that they can move smoothly to a parking space. Patent Document 1 proposes a guidance technology that includes a display means that displays guidance to users on lighting installed in the parking lot, and an imaging means that captures an image of the user, and a guidance control means that detects the user based on image information captured by the imaging means and controls the display on the display means. The display means is provided with a projection device that projects a required light pattern onto the floor of the parking lot.

[0003] Furthermore, Patent Document 2 proposes a guidance technology in which, when parking a vehicle in a suitable parking area within a parking space, a number of lights are arranged on the floor of the parking lot and these lights are selectively turned on to guide the user to the parking position. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2023-69105 [Patent Document 2] Japanese Patent Publication No. 2023-136353 Summary of the Invention [Problem to be solved by the invention]

[0005] The guidance technology of Patent Document 1 is configured to project a desired light pattern onto the road surface, walls, etc. of a parking lot, and by appropriately changing the light pattern, it is possible to provide suitable guidance. However, a projection device that can change the projected light pattern in this way requires the inclusion of high-cost devices such as a liquid crystal display device or an image forming device. Therefore, in order to provide suitable guidance to users throughout the entire area of ​​a large parking lot, the number of projection devices will increase, resulting in a problem of high costs.

[0006] The technology in Patent Document 2 uses low-cost lamps, so it is cost-effective even when a large number of lamps are used. However, while it is possible to indicate parking spaces by turning on the lamps, it is difficult to provide appropriate guidance to users moving through the parking lot.

[0007] An object of the present invention is to provide a guidance device and a guidance system that can be constructed at low cost and that can guide a user in an appropriate manner. [Means for solving the problem]

[0008] The present invention provides a guidance device that is provided in a location where a plurality of partitioned areas are provided for users to use, and that guides users who use the partitioned areas, and that includes lighting means that are provided in at least the plurality of partitioned areas to illuminate the partitioned areas, projection means that project a required light pattern onto the floor surface of the partitioned areas, and sound generation means that emits sound to users present in the partitioned areas and their neighboring areas.The guidance device has the lighting means, projection means, and sound generation means assembled together.

[0009] The guidance device of the present invention preferably includes an outer housing formed in a cylindrical container shape, an inner housing disposed within the outer housing, an illumination unit assembled to the outer housing, and the projection means and sound generation means assembled to the inner housing. In this configuration, a projection outer lens is disposed in an opening of the inner housing, and an annular illumination outer lens is disposed around the projection outer lens, with the annular gap between the projection outer lens and the illumination outer lens serving as a sound generation opening for the sound generation means. Furthermore, the projection means is configured to project the shape of the light-transmitting portion provided in the projection outer lens as a light pattern, and the sound generation means is configured to include a speaker.

[0010] The present invention also provides a guidance system that is provided in a location having a plurality of zones for users to use, and that guides users present in the location to the zones or other areas, the system comprising: a sensor that detects users present in the location; a plurality of guidance devices disposed in at least the plurality of zones; and a control device that is connected to the sensors and the guidance devices and controls the guidance devices based on user detection information detected by the sensors. The guidance devices further comprise a lighting means that illuminates the zones, a projection means that projects a required light pattern onto the floor of the zones, and a sound generation means that emits sound toward the zones and their neighboring areas, and the control device drives and controls the lighting means, projection means, and sound generation means.

[0011] In the guidance system of the present invention, the control device selectively or collectively drives and controls, among the multiple guidance devices, those that are present along the user's travel route. Alternatively, the control device sequentially drives and controls the multiple guidance devices along the user's travel route. In this control, the control device performs at least one of projecting and displaying a light pattern in a zone available to the user using a projection device, illuminating the zone with a lighting device, and emitting a sound in the zone with a sound generation device. [Effects of the Invention]

[0012] According to the guidance device and guidance system of the present invention, the guidance device is equipped with a lighting means, a projection means, and a sound generation means, which are assembled together, so that it can be constructed at low cost, and since guidance is provided using multiple guidance devices, it is possible to provide the user with suitable guidance.

[0014] Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram of an embodiment in which the present invention is applied to a guidance system in a parking lot PA. FIG. 2 is a schematic diagram of the interior of the parking lot PA. As shown in FIG. 1, the parking lot PA is divided into multiple parking spaces PS, and a vehicle to be parked can enter the parking lot PA through an entrance PI, travel along an aisle PW within the parking lot PA, and park in any of the parking spaces PS. Although not shown in FIG. 1, it is also possible to travel along the aisle PW from each parking space PS and exit the parking lot PA from an exit.

[0015] As shown in FIGS. 1 and 2, sensors 2 are provided at multiple locations in the parking lot PA, enabling the detection of users (vehicles and people) present within the parking lot PA. Only one sensor 2 is shown in FIGS. 1 and 2. Here, the sensor 2 is comprised of an imaging camera 21, which captures images of the area within the parking lot PA, including the parking spaces PS and aisles PW. Although not shown, the sensor 2 also includes an image processing unit, which performs image analysis on images captured by the imaging camera 21 to detect the status of the parking spaces PS within the parking lot PA and users present within the parking lot, and output the detection information. Multiple sensors 2 are provided on the ceiling, walls, pillars, etc. of the parking lot PA, and by integrating the detection information from each sensor 2, it is possible to output detection information for users present within all parking spaces PS and aisles PW within the parking lot PA.

[0016] Furthermore, multiple guidance devices 1 are disposed within the parking lot PA. The multiple guidance devices 1 are disposed corresponding to at least all of the parking spaces PS and also corresponding to multiple locations on the aisles PW within the parking lot PA. In this embodiment, one guidance device 1 is disposed above each of the multiple parking spaces PS, in this case on the ceiling, and multiple guidance devices 1 are disposed on the ceiling of the aisles PW that connect the entrance to the parking lot PA to each parking space PS, along the aisles PW.

[0017] Details of these guidance devices 1 will be described later, but they are equipped with a lighting means for illuminating an area including the corresponding parking space PS, a projection means for projecting a light pattern of a required shape onto a part of the parking space PS or the floor of the passage PW in the vicinity thereof, and a sound generation means for emitting sound to users in the vicinity of the parking space PS.

[0018] The above-mentioned multiple sensors 2 and multiple guidance devices 1 are connected to a control device 3 arranged in a part of the parking lot PA. This control device 3 controls the guidance device 1 based on the detection information output from each sensor 2. As shown in the schematic block configuration of Fig. 2, the control device 3 includes a recognition unit 31 that recognizes the state of the parking space PS, the user's position in the parking lot and any changes in that position based on the detection information, and a guidance control unit 32 that controls the multiple guidance devices 1 based on this recognition.

[0019] The recognition unit 31 recognizes and even predicts user behavior based on the recognized user position and its position change. For example, it recognizes whether a detected vehicle is entering or exiting, or it recognizes the relative positions of vehicles and people. The guidance control unit 32 controls the guidance operations of multiple guidance devices 1 based on the recognition by the recognition unit 31 so that users can move safely and smoothly. Here, the guidance device 1 is provided with a lighting control unit 321, a projection control unit 322, and a sound control unit 323 for controlling the three functions described above in the guidance device 1, namely, the lighting function, the projection function, and the sound generation function, respectively.

[0020] Fig. 3 is an external perspective view of the guidance device 1, and Fig. 4 is a central horizontal cross-sectional view taken along line HH in Fig. 5. Fig. 5 is a partially exploded perspective view of the overall configuration. The guidance device 1 has an outer housing 100 formed roughly in the shape of a cylindrical container, and this outer housing 100 incorporates an illumination unit 10 as illumination means and a projection / sound unit 20 as projection means and sound means. The outer housing 100 has a flange portion 101 that bulges outward along the circumference of a portion of the opening side, and the illumination unit 10 is disposed within this flange portion 101. The projection / sound unit 20 is configured within an inner housing 200 that is a cylindrical container one size smaller than the outer housing 100, and is disposed in the central region of the outer housing 100.

[0021] The lighting unit 10 is disposed within a circular chamber defined by the flange portion 101 of the outer housing 100, and includes a light source 11, an inner lens 12, a reflector 13, and an outer lens 14. The light source 11 includes a plurality of LEDs (light-emitting diodes) 11b mounted on a circular light source substrate 11a. The inner lens 12 is comprised of two rod-shaped light guides 12a, each bent into a semicircular arc shape with both ends 12b facing the LEDs 11b. Light emitted from the LEDs 11b is directed into the interior through the ends 12b. The reflector 13 surrounds the light source 11 and the inner lens 12 and reflects light emitted from the circumferential surface of the inner lens 12 toward the opening in the flange portion 101. The outer lens 14 is comprised of a circular, light-transmitting member, such as a transparent resin plate, attached to the front opening of the flange portion 101 to cover it.

[0022] In this lighting unit 10, when the lighting LED 11b is powered and emits light, light emitted from the lighting LED 11b enters the lighting inner lens 12a from the end 12b of the lighting inner lens 12a and is guided circumferentially within the lighting inner lens 12a. This guided light is then emitted from the circumferential surface of the lighting inner lens 12a, with a portion directed toward the lighting outer lens 14 and another portion reflected by the lighting reflector 13 and directed toward the lighting outer lens 14. These light beams then pass through the lighting outer lens 14 and are emitted as illumination light. As shown in FIG. 2 , the emitted light illuminates a substantially circular or annular area Ls on the floor surface that includes the parking space PS. To achieve uniform illumination, the surface of the lighting outer lens 14 may be configured as a diffusing surface. Alternatively, the lighting outer lens 14 may have a lens function that converges or diverges light, thereby illuminating a desired area.

[0023] Fig. 6 is an exploded perspective view of the projection / sound unit 20, and will be described with reference to Fig. 4 as well. The inner housing 200 is formed in the shape of a cylindrical container, and when it is installed inside the outer housing 100, a cylindrical space S is defined between the outer surface of the inner housing 200 and the inner surface of the outer housing 100 by a spacer or the like (not shown in the figure). An opening 201 is provided in the bottom surface of the inner housing 200, and a speaker 21 is attached inside the inner housing 200 so as to face this opening 201. For example, a dynamic speaker is attached with its cone facing the opening.

[0024] A light source unit 22 is disposed around the speaker 21 on the inner bottom surface of the inner housing 200. The light source unit 22 includes an annular circuit board 22a. A plurality of projection LEDs 22b, whose light-emitting surfaces face the opening of the inner housing 200, are mounted on the circuit board 22a and arranged in the circumferential direction. A sound generating circuit for driving the speaker 21 may also be configured on the circuit board 22a. A projection inner lens 23 is mounted on the circuit board 22a so as to face the light-emitting surfaces of the projection LEDs 22b. A plurality of lens steps 23a are integrally formed on the projection inner lens 23, each of which is disposed opposite the light-emitting surfaces of the projection LEDs 22b. These lens steps 23a function as condenser lenses that convert the light emitted from each projection LED 22b into a nearly parallel beam, and are configured as lens steps that form a TIR (total internal reflection) lens, for example.

[0025] Furthermore, a composite projection reflector 24 is disposed in front of the projection inner lens 23 within the inner housing 200. This projection reflector 24 is composed of an outer reflector 24a shaped like an inverted cone, the inner surface of which is a reflective surface, and an inner reflector 24b shaped like an inverted cone, the outer surface of which is a reflective surface, located at the center of the outer reflector 24a. Additionally, a circular projection outer lens 25 is attached to the opening of the inner housing 200. This projection outer lens 25 has a light-transmitting portion 25a with a required pattern formed in its central region, and the remaining region is composed of an opaque portion formed by vapor deposition or coating of an opaque material. This light-transmitting portion 25a has a rectangular pattern.

[0026] In this projection / sound production unit 20, when the speaker 21 is driven, sound generated by the vibration of the cone is propagated within the annular gap S between the inner housing 200 and the outer housing 100, and is emitted outside the guidance device 1 from the gap between the lighting outer lens 14 and the projection outer lens 25. The sound from the speaker 21 is emitted from the annular gap S facing the front side of the guidance device 1, and therefore has a highly directional characteristic. Therefore, it is possible to selectively play the sound to users who are in the vicinity of the parking space PS where the guidance device 1 is installed.

[0027] Furthermore, when the projection LEDs 22b are powered and emit light, the light emitted from each projection LED 22b is collimated by the lens step 23a, reflected by the inner reflective surface of the outer reflector 24a toward the center, and then reflected by the outer reflective surface of the inner reflector 24b toward the opening of the inner housing 200. It is preferable that the reflective surfaces of the outer reflector 24a and the inner reflector 24b are arranged parallel to each other. In this way, the center of the beam (optical axis) of the light emitted from the projection LEDs 22b and collimated by the lens step 23a is directed in a direction perpendicular to the light-emitting surface of the projection LED 22b, i.e., in a direction perpendicular to the lens surface of the illumination outer lens 25, even after being reflected by the projection reflector 24.

[0028] Furthermore, it is preferable that the centers of curvature of the reflective surfaces of the outer reflector 24a and the inner reflector 24b coincide. In this way, the light beam collimated by the lens step 23a is reflected by the outer reflector 24a and converged in the circumferential direction, but is reflected by the inner reflector 24b and diverged in the circumferential direction, compensating (complementing) each other and preventing significant deformation of the beam shape. As a result, the light emitted from each projection LED 22b is focused in the central region of the projection outer lens 25, transmitted through the light-transmitting portion 25a, and converted into a rectangular beam of light corresponding to the shape of the light-transmitting portion 25a. As shown in FIG. 2, this allows the projection of a highly bright light pattern resulting from the combined light of the multiple projection LEDs.

[0029] In this embodiment, a guidance system is constructed by disposing a plurality of guidance devices 1 having the above configuration in the parking spaces PS of the parking lot PA shown in FIG. 1. Furthermore, in this embodiment, the guidance devices 1 are also disposed at appropriate intervals along the passage PW from the entrance PI or exit of the parking lot PA to the parking spaces PS. As described above, the guidance device 1 of the embodiment does not include a configuration such as a liquid crystal device for controlling the projection pattern or projection position, as in Patent Document 1. Therefore, even if a guidance device 1 is disposed in each of a large number of parking spaces PS, the overall cost can be kept low. Furthermore, compared to the lamp configuration that simply emits light, as in Patent Document 2, the guidance device 1 of the embodiment includes a projection means for projecting a desired light pattern Lp and a sound generation means for emitting sound.

[0030] According to the guidance system configured in this way, the following guidance control is possible for the user. (Guidance to parking space) FIG. 7 is a schematic diagram of an example parking lot to explain guidance control. When a vehicle C1 enters the parking lot PA through an entrance PI, the sensor 2 detects the vehicle C1 from the captured image and outputs detection information. The recognition unit 31 of the control device 3 shown in FIG. 2 recognizes the entering vehicle C1 based on the detection information from the sensor 2, and also detects and recognizes an empty parking space. Then, if the detected vehicle C1 is recognized as a vehicle to park, the guidance control unit 32 controls the guidance device to the empty parking space PS (PS1).

[0031] For example, all of the guidance devices 1 installed between the position where vehicle C1 is located and the vacant parking space LS1 are driven, and their projection and sound units 20 are driven to project a light pattern Lp. In Fig. 7, this is a solid light pattern Lp. As a result, a plurality of light patterns Lp are projected in a continuous state from the position where vehicle C1 is located to the vacant parking space LS1, and vehicle C1 can reach the vacant parking space LS1 by following this.

[0032] At this time, the light pattern Lp may be projected and disappeared sequentially from the guidance device 1 closest to the vehicle C1 toward the guidance device 1A of the vacant parking space LS1. That is, sequential projection of the light pattern Lp may be performed. The occupant of the vehicle C1 can easily reach the vacant parking space LS1 by visually recognizing the sequentially projected light pattern Lp and moving along the flow of the light patterns Lp. The projection of the sequential light pattern Lp may be performed by tracking the moving position of the vehicle C1 in real time. Note that the guidance device 1 stops projecting the light pattern once the vehicle C1 has passed.

[0033] (Parking space display) Next, when the recognition unit 31 of the control device 3 recognizes that the vehicle C1 has moved close to a vacant parking space, the guidance control unit 32 drives the lighting unit 10 of the guidance device 1 (1A) for the vacant parking space LS1 to illuminate the parking space LS1. At the same time, a sound may be emitted from the speaker 21 of the projection / sound unit 20 to notify the driver that the location is a vacant parking space. The occupants of the vehicle C1 recognize that the parking space is for their vehicle C1 through this lighting and projection, allowing them to park smoothly.

[0034] (Guidance to the exit) Although not shown in the figure, similar guidance can be performed when a vehicle parked in a parking space LS exits through an exit. That is, all guidance devices 1 arranged between the parking space LS and the exit are driven, and the projection / sound units 20 of the guidance devices 1 are driven to project the light pattern Lp. As a result, multiple light patterns Lp are projected in a continuous state from the parking space LS where the vehicle was parked to the exit, and the vehicle can reach the exit by following these patterns. At this time, sequential projection may be performed in which patterns are projected in order from a guidance device located closer to the vehicle toward a guidance device at the exit.

[0035] (Human safety guidance) FIG. 8 is a schematic diagram of another example of a parking lot to explain guidance control. Sensor 2 detects vehicles and people as users present in parking lot PA from captured images and outputs the detection information. Recognition unit 31 of control device 3 recognizes vehicles and people based on the detection information from sensor 2 and further predicts the moving positions of the vehicles and people. Here, it recognizes vehicle C2 entering and person M walking along passage PW, and recognizes the possibility of a collision between the two. If it predicts that the two may collide, guidance control unit 32 controls guidance device 1 (1B) located closest to the position where person M is present.

[0036] In this case, the light pattern LP may be projected and the illumination Ls may be turned on or off. The projection and sound unit 20 may also output a voice message from the speaker 21, such as "A vehicle is coming. Please be careful." This alerts the person M and helps to avoid a collision with the vehicle C2. In this case, when the person M is moving along the passage PW, the nearest guide device 1 may be driven in sequence, switching between them, to follow the person M's movement.

[0037] Also, as shown in FIG. 8, when a vehicle C3 is about to leave a parking space LS and a person M is present near the parking space LS, the guidance device 1 (1B) for the parking space LS is activated. At this time, the lighting unit 10 of the guidance device 1 may illuminate Ls, or the projection and sound unit 20 may project a light pattern Lp, or even sound may be emitted. In this case, for example, a message such as "A vehicle is moving. Please be careful" may be emitted to alert the person.

[0038] (Guidance of vehicle occupants) Although not shown in the drawings, the guidance system of the present invention may register in advance the vehicle and its occupant parked in a parking lot. For example, when parking, the vehicle and occupant are registered in the control device 3 using a mobile terminal carried by the occupant. When the parked occupant returns to the parking lot and attempts to leave in the vehicle, the control device 3 can guide the occupant to the vehicle by activating a guidance device located between the occupant's current position and the vehicle. At this time, the guidance device for the parking space where the occupant parked can illuminate the parking space and play a sound.

[0039] The guidance device of the present invention is not limited to the configuration of the embodiment, and may be modified as appropriate, as long as it includes an illumination means, a projection means, and a sound generation means. For example, the projection means and the sound generation means do not have to be configured as a projection / sound generation unit as in the embodiment, but may be configured as independent units. Alternatively, the illumination means may be configured as a unit integrated with the projection means or the sound generation means.

[0040] The light emitted by the lighting LED 11b as the light source of the lighting unit 10 of the guidance device or the projection LED 22b as the light source of the projection and sound unit 20 is not limited to a single color, but may be multicolored. For example, the colored light used to illuminate an empty parking space, the colored light used to project a light pattern, the colored light used to guide the user along the route to an empty parking space, and the colored light used to guide the user along the route to the exit may be different. Alternatively, when multiple vehicles are moving simultaneously in the parking lot, different colored lights may be used to guide each vehicle.

[0041] The shape of the light pattern projected by the guidance device of the present invention is not limited to the rectangular pattern described in the embodiment, but may be various shapes such as an arrow pattern, a triangular pattern, etc. Furthermore, each guidance device may be configured to selectively or collectively project multiple patterns.

[0042] In the embodiment, the present invention is applied to a parking lot, but it can also be applied to any place that is not called a parking lot, where vehicles are temporarily stopped or parked. It can also be applied to guiding users in places where many users gather, such as event venues that have multiple partitioned areas such as multiple sales corners and exhibition corners.
