Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a height detecting means for detecting whether or not the height of the stored vehicle is within a set allowable range at a specific location of an external communication portion for storing the vehicle. Is provided, and based on the information of the height detection means, the three-dimensional parking lot is provided with an abnormality processing means that operates when the height of the stored vehicle is outside the set allowable range.

[0002]

2. Description of the Related Art Conventionally, in this type of multi-story parking lot, an abnormality processing means that operates when the height of a parked vehicle is out of a set allowable range is an object whose height detecting means is out of the set allowable range. When it is detected, it is always activated (see, for example, Japanese Patent Application No. 4-2672). Therefore, even if the object is a human being, if the height thereof is outside the set allowable range, the abnormality processing means is operated.

[0003]

However, in general, the vehicle height of a passenger car is lower than the average height of a standing human being, and therefore, the setting allowable range is also the same as that of a standing human being. Since it is often set to be lower than the average height, according to the above-mentioned conventional technology, the driver who has finished storing the vehicle passes through the specific place where the height detecting means is provided, and When leaving the outside,
The height detection means will detect the driver. Therefore, even if the height of the parked vehicle is within the set allowable range, the abnormality processing means will be activated. Was there. The purpose of the present invention is to
The point is to eliminate the above-mentioned conventional drawbacks.

[0004]

According to a first characteristic configuration of a multi-storey car park according to the present invention, an object detected by the height detecting means at the specific place is the vehicle or a human. The determination means for determining whether or not is provided, and the abnormality processing means is configured not to operate when the object is a human based on the information of the determination means.

The second characteristic configuration of the multi-storey parking lot according to the present invention specifies a preferred specific configuration for implementing the first characteristic configuration, and the discriminating means is stored in the external communication section. Another feature is that it is configured by front-rear width detection means for detecting whether or not the front-rear width of the vehicle is within a set allowable range.

[0006]

According to the first characteristic configuration of the present invention, the abnormality processing means does not operate based on the information of the discrimination means when the object detected by the height detection means is a human. Therefore, even if the driver who has finished entering the vehicle exits the multi-story parking lot through the specific location where the height detection means is provided, the abnormality processing means is activated. There is no.

According to the second characteristic configuration, the discriminating means is constituted by front-rear width detecting means for detecting whether or not the front-rear width of the vehicle stored in the external communication portion is within a set allowable range. Therefore, using the fact that the front-back width of a passenger car is generally wider than the average front-back width of a standing human being, is the object detected by the height detection means a vehicle? It is possible to determine whether it is a human being.

[0008]

According to the first characteristic configuration of the present invention, in the case where a driver who has finished storing a vehicle leaves the outside of the multi-story parking lot through the specific place where the height detecting means is provided. Also, since the abnormality processing means is not activated, a multi-storey parking lot that eliminates the inconvenience that the abnormality processing means is activated even if the height of the parked vehicle is within the set allowable range Can be provided.

According to the second characteristic configuration, the front-back width detecting means can determine whether the object detected by the height detecting means is a vehicle or a human being.
It is possible to provide a multi-story parking lot to which the present invention is applied, while simplifying the structure, reducing the number of parts, and without changing each conventional multi-story parking lot.

All of these sensors are configured by so-called photo coupler type photosensors, and have a light receiving portion and a light emitting portion, and the optical axis thereof is shown by a chain line. Hereinafter, these sensors will be described.

A vehicle height detection sensor 10 as a height detection means for detecting whether or not the height of the vehicle G stored in the loading / unloading port 2 is within the set allowable range W1 shown in FIG.
And a vehicle passage sensor 11 for detecting that the vehicle G has passed through the loading / unloading port 2.

The light receiving portion and the light emitting portion of the vehicle height detecting sensor 10 are provided on the inner side of the side frame of the loading / unloading port 2 with their optical axes extending in the lateral width direction at the opening of the loading / unloading port 2. Has been. The height of the optical axis of the vehicle height detection sensor 10 is
The set allowable range W determined based on the vertical width of the shelf 1
It is set to an upper limit height of 1. Therefore, when the vehicle G having a height exceeding the set allowable range W1 passes through the loading / unloading port 2, the vehicle G blocks the optical axis of the vehicle height detection sensor 10, so that the vehicle G has the set allowable range. W
It is detected that it is not within 1.

The light receiving portion and the light emitting portion of the vehicle passage sensor 11 are also provided on the inner side of the side frame of the loading / unloading port 2. However, its optical axis is set at a relatively low position and at a height where a general vehicle exists. Therefore, the entrance / exit 2
When the optical axis is blocked by the vehicle G passing through, the passage of the vehicle G at the loading / unloading port 2 is detected.

Inside the external communication portion B, the vehicle G stored in the external communication portion B having its optical axis stretched in the lateral width direction.
Front and rear protrusion sensor 12F as front and rear width detecting means for detecting whether or not the front and rear width is within the set allowable range W2,
12R, vehicle fixed position sensors 13F and 13R, left and right protrusion sensors 14L and 14R, and door opening sensors 15L and 15 that extend their optical axes in the depth direction.
R and vehicle displacement sensors 16a and 16b are provided.

The optical axes of the front and rear protrusion sensors 12F and 12R are along the respective edge lines of both longitudinal edges of the pallet P placed on the external communication portion B, and a general vehicle exists. The height is set, and the front limit and the rear limit of the setting allowable range W2 of the front-rear width of the stored vehicle G are defined by the distance between both optical axes. Therefore, depending on the vehicle body of the vehicle G, the front and rear protrusion sensor 12F
It is detected that the optical axis of the vehicle G has protruded to the inner side of the pallet P in the depth direction, and the optical axis of the front-rear protrusion sensor 12R is blocked, so that the vehicle G can move to the pallet P. It is detected that it is protruding to the front side in the depth direction, and further, both sensors 12
By blocking the optical axes of F and 12R at the same time, it is detected that the stored vehicle G has a front-rear width exceeding the setting allowable range W2.

The optical axes of the vehicle fixed-position sensors 13F and 13R are located between the optical axes of the front and rear protrusion sensors 12F and 12R, and are distributed on both sides of the center of the pallet P in the longitudinal direction. It is set to the height where the target vehicle exists. Therefore, it is detected that the vehicle G is mounted on the pallet P by blocking its optical axis by the vehicle body of the vehicle G, and further, the optical axis of only the vehicle fixed position sensor 13F is blocked, so that the vehicle G
Is detected to be biased toward the depth side of the pallet P, and the optical axis of only the vehicle fixed position sensor 13R is blocked, whereby the vehicle G is biased toward the front side of the pallet P in the depth direction. It is detected that the vehicle G is mounted, and the optical axes of both the sensors 13F and 13R are blocked, so that it is detected that the vehicle G is mounted at a fixed position on the pallet P.

The distance between the optical axes of the vehicle fixed position sensors 13F and 13R should be smaller than the front-rear length of a general vehicle, including a vehicle having a relatively short front-rear length such as a light vehicle. However, in order to effectively detect the deviation of the vehicle mounted on the pallet P, it is preferable that the width be as wide as possible.

The optical axes of the door opening sensors 15L and 15R are set to be substantially along both longitudinal side edges of the pallet P and at the height of the door of a general vehicle.
Therefore, when the door of the vehicle G mounted on the pallet P is opened, the optical axis of the vehicle G is blocked and the door opening is detected.

The optical axes of the vehicle displacement sensors 16a and 16b are
The height is set so as to be along both longitudinal edges of the elevating part 3 and at a height at which a general vehicle exists. Therefore, the pallet P is turned 90 degrees by the turning device 5,
When the vehicle G on the pallet P is displaced forward and backward when it is mounted on the elevating unit 3, the optical axis thereof is blocked and the vehicle displacement is detected.

The optical axes of the left and right protrusion sensors 14L and 14R are set to the upper limit of the setting allowable range W1 in a state of being along both lateral side edges of the elevating part 3 in the longitudinal direction. The distance between the optical axes of both the sensors 14L and 14R defines the left limit and the right limit of the lateral width setting allowable range W3 of the vehicle G, which is determined based on the vehicle storage space of the shelf 1. FIG. 4 shows the inside of the external communication portion B immediately after the ascending / descending portion 3 starts to rise. Vehicle G is
As it is raised by the elevating part 3, it always passes through the plane sandwiched by the optical axes of the left and right protrusion sensors 14L and 14R. Therefore, at any height of the vehicle G, even if there is a protruding portion that exceeds the set allowable range W3, the optical axis of the vehicle G is always shielded as the ascending / descending unit 3 rises, and the vehicle G is set to the set allowable range W3. Not located within is detected.

FIG. 5 shows a control mechanism H for a multilevel parking lot according to this embodiment. The control mechanism H has a control unit 17 including a microcomputer as a main part, and includes a management device 1
8, the drive device 9, and the turning device 5 are connected to manage the lifting operation of the lifting unit 3 and the turning operation of the turntable 5a of the turning device 5 in accordance with a storage command or a shipping command from the management device 18. It is configured.

Further, the control unit 17 includes all the sensors 10, 11, 12F, 12R, 13F, 13R, 1 described above.
4L, 14R, 15L, 15R, 16a, 16b, an emergency stop button 19, and a guide plate 20 are connected,
An abnormality processing unit 101 that manages the lifting operation of the lifting unit 3, the turning operation of the turning device 5, and the display of the guide plate 20 is configured based on the information sent from the sensor and the signal from the emergency stop button 19. .

Based on the information from the vehicle height detection sensor 10, the abnormality processing means 101 should prohibit the raising / lowering operation of the raising / lowering section 3 when the height of the stored vehicle G is outside the set allowable range W1. , Configured to operate.

As shown in FIG. 6, the management device 18 is provided on the side of the entrance / exit 2 on the outer wall side of the multilevel parking lot.
The management device 18 is provided with a so-called touch panel type display screen 18a. The emergency stop button 19 is provided on the inner wall surface in the lateral width direction near the entrance / exit port 2 inside the external communication part B, and can perform various emergency stop operations of the multi-storey parking lot under the control of the control mechanism H. The guide plate 20 is provided inside the external communication portion B on the front side on the back side in the depth direction, and various guides are displayed by electronic bulletin boards.

When the abnormality processing means 101 is activated, a report to a person using the multi-storey parking lot, such as a driver or a manager, is shown in FIG. 7 on the display screen 18a provided in the management device 18. So-called multi-
This is performed by displaying the message 21 in the window system. In addition, once the abnormality processing means 101 is activated, unless a command for canceling the operation of the abnormality processing means 101 is given from the management device 18 by a person who uses the multi-storey parking lot, the control unit 17 is It is configured so that the following operations relating to the entry or exit of the vehicle G cannot be performed.

Further, the front and rear protrusion sensor 12R provided near the entrance / exit 2 is detected by the height detecting means, that is, the vehicle height detecting sensor 10 at the specific location, that is, the entrance / exit 2. The target object also functions as a determination unit that determines whether the target object is the vehicle G or a human.

FIG. 9 shows a state in which the vehicle G outside the set allowable range W1 is passing through the loading / unloading port 2.
In this case, the optical axis of the vehicle height detection sensor 10 is blocked by the upper portion of the vehicle G. However, since the vehicle G has a certain front-rear width, the vehicle G has the front-rear protrusion sensor 12R at the same time. The optical axis is also blocked. Therefore, when the optical axis of the vehicle height detection sensor 10 is blocked and at the same time the optical axis of the front-rear protrusion sensor 12R is also blocked, when the object detected by the vehicle height detection sensor 10 is the vehicle G. It corresponds.

FIG. 10 shows a state in which the driver who has finished loading the vehicle G is passing through the loading / unloading port 2. In this case, the optical axis of the vehicle height detection sensor 10 is blocked by the upper part of the driver. However, since the driver does not have the front-rear width as that of the vehicle G, the optical axis of the front-rear protrusion sensor 12R is blocked at the same time. I can't.
Therefore, when the optical axis of the vehicle height detection sensor 10 is blocked, but the optical axis of the front-rear protrusion sensor 12R is not blocked, when the object detected by the vehicle height detection sensor 10 is a human being. It corresponds.

The abnormality processing means 101 operates when the optical axis of the vehicle height detection sensor 10 is blocked and the optical axis of the front and rear protrusion sensor 12R is blocked, but the optical axis of the vehicle height detection sensor 10 is blocked. Even if the axis is blocked, it is configured not to operate unless the optical axis of the front and rear protrusion sensor 12R is blocked. Therefore, the abnormality processing means 10
1 is based on the information of the front and rear protrusion sensor 12R,
When the object detected by the vehicle height detection sensor 10 is a human, it is configured not to operate.

The warehousing operation of the vehicle G in the multilevel parking lot of this embodiment is performed as follows. The inside of the external communication part B is in the state shown in FIG. After unloading the passengers other than the driver, the vehicle G enters the external communication section B through the loading / unloading port 2. The entry of the vehicle G is detected by the vehicle passage sensor 11, and the guide plate 20 goes straight on to the pallet P.
A guide to stop is displayed at the fixed position above.

However, at this time, the vehicle height detection sensor 10
When it is detected that the height of the vehicle G is outside the setting allowable range W1 and at the same time the optical axis of the front and rear protrusion sensor 12R is blocked, the guide plate 20 and
Information indicating that an abnormality has been confirmed is displayed on the display screen 18a, and a message 21 shown in FIG. 7 is displayed. Until the storage switch command is given again by the touch switch 22 on the display screen 18a, the subsequent storing operations are performed. Stop the operation.

The vehicle G that has entered the external communication portion B goes straight on to reach the pallet P. First, since the presence / absence of the vehicle G is detected by the front and rear protrusion sensor 12R, a guide to the effect that the vehicle G should be moved a little further is displayed on the guide plate 20, and the display screen 18a is displayed as shown in FIG. The message 21 shown is displayed. After the vehicle detection by the front and rear protrusion sensor 12R disappears, if the vehicle is detected only by the vehicle fixed position sensor 13R, guidance indicating that the vehicle should move a little further and the message 21 shown in FIG.
Is displayed, and when the vehicle is detected only by the vehicle fixed position sensor 13F, guidance for further retracting and a message 21 shown in FIG. 8B are displayed. Further, when the vehicle is detected by both the vehicle fixed position sensors 13F and 13R and the presence of the vehicle is also detected by the front and rear protrusion sensor 12F, a guide to the effect that the vehicle should be moved backward a little and FIG. ) Is displayed, and if the presence or absence of the vehicle is not detected by either of the front and rear protrusion sensors 12F and 12R, the vehicle is stopped, fixed, and a guide to the effect that the vehicle should get off is displayed. Then, if a vehicle is also detected by the front and rear protrusion sensor 12F before the vehicle detection by the front and rear protrusion sensor 12R disappears, a message indicating that an abnormality is confirmed and a message 21 shown in FIG. 8D are displayed. , Once vehicle G is in / out port 2
The subsequent operations relating to the warehousing work are stopped until the user exits to the outside of the external communication section B through the.

The driver gets off from the vehicle G mounted on the pallet P and comes in front of the management device 18.
Then, after confirming the safety inside the external communication section B, the control mechanism H is instructed to start the subsequent operation relating to the warehousing work. At this time, when the door opening sensor 15L, 15R detects the door opening, a guide indicating that the abnormality is confirmed is displayed on the guide plate 20, and the message 21 shown in FIG. The subsequent operation is stopped until it is displayed and the management device 18 is again instructed to start the warehousing operation. When the door opening is not detected, the pallet P is swung 90 degrees by the swivel device 5 and moved above the elevating part 3 with its longitudinal direction oriented in the lateral width direction. At this time, the vehicle G may shift back and forth on the pallet P due to, for example, forgetting to apply the side brake. When a vehicle shift is detected by the vehicle shift sensors 16a and 16b, the warehousing operation is stopped urgently.

If no vehicle deviation is detected, the elevator 3
The pallet P is transferred onto the elevating part 3 as the height is raised, and further raised toward the predetermined shelf 1. At this time,
When the left and right protrusions are detected by the left and right protrusion sensors 14L and 14R, a guide indicating that the abnormality is confirmed is displayed on the guide plate 20, and the display screen 18a is shown in FIG.
