Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for detecting the presence of a vehicle in a parking facility, and more particularly to a multi-stage parking facility having a gate in front of a passenger compartment on a boarding surface.

[0002]

2. Description of the Related Art For example, in a three-stage type parking facility in which a vehicle housing room is constituted by an upper stage and a middle stage above the ground and a lower stage below the basement by columns and beams, predetermined upper and lower stages are provided. A parking pallet having the number of parking rows is provided, and a transverse pallet having a number of rows one less than the number of parking rows in the upper or lower row is provided in the middle row, which is a boarding plane. In addition, a gate is provided in front of the cabin on the entry surface to prevent people from entering the facility during pallet operation.The gate opens when vehicles enter and exit from the entry surface. It is. When the vehicle detection device is provided in such a multi-stage parking facility, for example, as shown in FIG. 5, a diffuse reflection type is provided near the stop position of the wheel T of the parking vehicle C on all pallets 2 (or 3). The detector 50 was installed.

[0003] However, in this vehicle presence detection device, diffuse reflection type detectors for all pallets are required, so that the cost is increased and the device is complicated due to wiring and the like. In addition, although the diffuse reflection type detector is a precision optical device, it is installed below the vehicle, so it is contaminated by dust from the wheels and exhaust gas from the muffler, causing false detections, and users and wheels. However, there is a problem that it is damaged by contact.

Therefore, as shown in FIG. 6, a cross beam 5a is passed from the support post 5 at the rear of the passenger compartment to the height of the rear end of the vehicle, and a diffuse reflection type detector 50 is installed on the cross beam 5a to constitute an in-vehicle detection device. Proposed. If the diffuse reflection type detector 50 is installed at a certain high position in this way, the degree of contamination and breakage can be reduced. In general, in this type of multi-stage parking equipment, the stopped state of the pallets is always detected, and it is possible to store in the control device which pallets are being lifted and stopped on the boarding surface for entry / exit. . Therefore, if the in-vehicle information on the pallets after the completion of the entry / exit movement is newly stored in the control device, it is possible to detect the presence of all the pallets with only the diffuse reflection type detectors corresponding to the number of parking rows on the boarding surface. It is possible to reduce the required number of diffuse reflection detectors,
The cost can be reduced and the structure can be simplified.

[0005]

However, in the conventional vehicle presence detection device, since the shape of the rear end of the vehicle differs depending on the type of vehicle, the distance between the diffuse reflection type detector and the rear end of the vehicle is unstable. There is a problem that there are many erroneous detections due to the influence of the body color and the material of the reflection portion (steel plate, glass, plastic, attachment of a sticker, etc.).

The present invention has been developed in view of these problems, and provides an in-vehicle detection device for a parking facility which has a simple structure, is low in cost, and has less erroneous detection, damage to a detector, and less pollution. The purpose is to do so.

[0007]

In order to achieve the above object, according to the present invention, an apparatus for detecting the presence of a vehicle in a parking facility according to the first aspect of the present invention is a multi-stage type having a gate in front of a cabin on a boarding surface. An on-vehicle detection device for a parking facility, wherein a mirror reflection type detector is provided behind the cabin on the entrance surface, and a reflection mirror is provided on a gate.

The mirror-reflecting detector emits light by itself, receives the light reflected by the reflecting mirror, and detects the presence or absence of the light. If there is a vehicle, the light is blocked and the presence of the vehicle can be detected. In the invention, in the parking facility detecting device for a parking facility according to claim 2, in the invention according to claim 1, the mirror reflection type detector is positioned upward and the reflecting mirror is positioned downward in a side view of the vehicle cabin. And are arranged diagonally.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are overall views of a multi-stage parking facility provided with the vehicle presence detection device of the present invention. The parking device 1 has three rows of cabins 1 at two levels above the ground and one level below the ground.
Numeral 0 is formed by the struts 5, and three rows of lifting pallets 2 are provided in the upper row and the lower row in the pit P.
The boarding plane G where the vehicle C enters and exits is provided with one row less than the upper row and the lower row, that is, two rows of horizontal pallets 3. The lifting pallet 2 is stopped by the motor 4 and the chain 4a, and the stop position thereof is controlled by a detector such as a proximity switch (not shown). The traversing pallet 3 is traversed on a traversing rail (not shown) by a traversing device (not shown), and its stop position is controlled by a detector such as a proximity switch (not shown). A series of these operations and controls are performed by an operation panel 8 provided on the support 5 on the front of the vehicle compartment and a control panel 9 provided on the support 5 on the rear. The figure shows a state in which the lifting pallet 2 at the right end of the ground stage is descending on the boarding surface G.

[0010] A gate 6 for preventing a person from entering the equipment during the operation of the pallet is provided on the front column 5 so as to be movable up and down by a motor 6a and a chain 6b. A reflecting mirror 7b is attached to the gate 6 below a central portion of each of the passenger compartment rows. On the other hand, a cross beam 5a is hung over a support column behind the passenger compartment of the entry plane G, and a mirror reflection detector 7a is provided at the center of each passenger compartment row.
The in-vehicle detection device 7 is composed of the mirror reflection type detector 7a and the reflection mirror 7b. The positional relationship between the two is, as shown in FIG. 7a
Are arranged diagonally facing each other with the reflecting mirror 7b facing downward.

Next, a case where the vehicle C is stored in the parking device 1 will be described. First, when a command to call an empty pallet is given to the operation panel 8, the vehicle is loaded on the pallet 2 at the upper stage based on the on-vehicle data on the pallet stored in the control device in the control panel 9 in advance. The pallet under the empty pallet is traversed or lowered to secure a space for the pallet 2 to descend, and the pallet 2 is placed on the loading surface G.
Down to When the lowering of the lifting pallet 2 is completed,
The gate 6 is raised to allow the vehicle C to enter the device. At this time, since the reflecting mirror 7b is raised together with the gate 6, the reflecting mirror 7b is not damaged or soiled by the vehicle C or the user.

When the placing of the vehicle C on the elevating pallet 2 is completed, and a command is issued to the control panel 8 to indicate that the storage is completed, the gate 6 is lowered. When the lowering of the gate 6 is completed, the vehicle detection device 7
Detects the presence or absence of the vehicle C on the lifting pallet 2. Here, the vehicle C is placed on the elevating pallet 2 at the same level as the entry plane G.
Is mounted, the light emitted from the mirror reflection type detector 7a is irregularly reflected by the body or glass of the vehicle C, or is absorbed in the vehicle C even if the light passes through the glass. The reflected light does not reach the detector 7a. In this way, the light is blocked by the vehicle C, so that “vehicle is present”
That is, the presence of the vehicle is detected. This in-vehicle data is stored in the control device together with the pallet number.

Next, a case in which the vehicle C stored in the parking device 1 is left will be described. First, the number of the lifting pallet 2 on which the vehicle C to be unloaded is placed is input (here, the vehicle C is assigned to the upper lifting pallet 2).
Is placed on the pallet), and when a "pallet call" is instructed, the pallet below the corresponding lifting pallet 2 is moved or lowered to secure a space for the lifting pallet 2 to descend. Is lowered to the boarding plane G. When the lowering of the lifting pallet 2 is completed, the gate 6 is raised to allow the user to enter the apparatus and to leave the vehicle C.

When the exit of the vehicle C from the elevating pallet 2 is completed and the control panel 8 is instructed to "complete the exit," the gate 6 is lowered. When the lowering of the gate 6 is completed, the vehicle presence detection device 7 detects the presence or absence of the vehicle C on the lifting pallet 2. When the vehicle C is not mounted on the pallet of the boarding surface G, the light emitted from the mirror reflection type detector 7a is reflected by the reflection mirror 7b.
And is received again by the mirror reflection type detector 7a.
"No vehicle", that is, the absence of the vehicle is detected.
This in-vehicle data is also stored in the control device in the control panel 9 together with the pallet number.

The above is a case where the in-vehicle detection device of the present invention is applied to a parking device for placing a vehicle on an unspecified empty pallet, such as a parking lot for hourly rental. The present invention is also applicable to a parking device provided with an ID tag calling device that carries a non-contact memory card (hereinafter, referred to as an ID tag) and controls pallet calling based on data stored in the ID tag.

As shown in FIG. 4, the configuration of the ID tag calling device 60 comprises an ID tag 70, an operation panel 80, and a control panel 90, and the other configurations of the parking device are the same as those shown in FIGS. Good. The ID tag 70 is a non-contact type memory card, and can transmit and receive data without contact when it is within the detection range. The operation panel 80 includes, for example, a display / audio unit 80a and a data input / output unit 80b, and the control panel 90 includes a command unit 90a, a calculation unit 90b, and a control unit 90c.

The display / audio unit 80a displays message information such as the operating state and the failure state of the parking device 1 sent from the command unit 90a in a visual and audio manner, and provides a visual and audible operation guidance to the user. I do. Data input / output unit 80
b transmits and receives pallet information and operation information between the operation unit 90b and the ID tag 70, but has an antenna for transmitting and receiving data to and from the ID tag 70 in a non-contact manner. Further, the control unit 90c, based on the pallet information from the calculation unit 90b, inputs data from the in-vehicle detection device 7 and various detectors to the electric control devices such as the motors 4 and 6a and the fall prevention solenoid. It outputs a control signal and feeds back data to the command unit 90a and the arithmetic unit 90b.

For example, as described above, the upper pallet 2
When the vehicle C is stored in the ID tag 70, the corresponding pallet number is stored in the ID tag 70. Then, the user inserts the ID tag 70 into the data input / output unit 80 for retrieval.
When the distance approaches “b”, the data input / output unit 80b receives the corresponding pallet number from the ID tag 70 and transmits it to the calculation unit 90b. The control unit 90c starts the withdrawal operation of the corresponding lifting pallet 2 based on this data and the vehicle presence data “vehicle present” on the pallet stored in advance by the vehicle presence detection device 7.

That is, the pallet below the corresponding lifting pallet 2 is traversed or lowered to secure a space for lowering the lifting pallet 2, and the lifting pallet 2 is lowered to the loading surface G. When the lowering of the lifting pallet 2 is completed, the control panel is instructed to "gate up" to raise the gate 6,
The user can enter the device and exit the vehicle C. During this time, the user moves away from the front of the operation panel 80 (ID
When the distance between the tag 70 and the data input / output unit 80b increases),
A safety device is activated to stop the device.

When the exit of the vehicle C from the elevating pallet 2 is completed and a "gate descent" command is issued to the control panel 80, the gate 6 is lowered. When the lowering of the gate 6 is completed, the in-vehicle detecting device 7 detects "no vehicle" on the elevating pallet 2, and the in-vehicle data "no vehicle" is stored in the control device together with the pallet number. The corresponding pallet number is stored in the ID tag 70 continuously.

Next, in order for the user to enter the vehicle C,
When the D tag 70 is moved closer to the data input / output unit 80b, the data input / output unit 80b receives the corresponding pallet number from the ID tag and transmits it to the calculation unit 90b. The control unit 90c starts the warehousing operation based on this data and the occupancy data “no vehicle” on the pallet stored in advance by the occupancy detection device 7, but at this time, the traversing pallet 3 and other If the vehicle C is not placed on the lifting pallet 2,
The control unit 90c transmits an arbitrary pallet (here, pallet) on the boarding plane G via the command unit 90a and the display / audio unit 80a.
(Referred to as traversing pallet 3). In this case, there is no need for the user to wait for the pallet to go up and down or to traverse. After the gate 6 has been commanded and the gate 6 has been lifted, the designated pallet 3 according to this display is displayed.
Place the vehicle on top.

When the mounting of the vehicle C on the traversing pallet 3 is completed, a "gate lowering" command is issued to lower the gate 6. When the lowering of the gate 6 is completed, the in-vehicle detection device 7 detects “vehicle present” on the traversing pallet 3. This stock data “vehicles present” is stored in the control device together with the pallet number. On the other hand, the pallet number of the changed traversing pallet 3 is newly stored in the ID tag 70.

As described above, by controlling the ID tag calling device 60 and the in-vehicle detection device 7 in combination, the user only needs to bring the ID tag 70 close to the data input / output unit 80b and instruct the gate to go up and down. Storage and retrieval can be performed, and the time required for storage can be reduced.

As is apparent from the above description, according to the present invention, according to the present invention, the mirror reflection type detector is provided at the rear of the cabin on the entrance surface, By providing a reflection mirror at the gate, it is possible to detect the presence or absence of a vehicle by reflecting the light beam from the detector with the reflection mirror, the distance to the reflection mirror is constant, and the state of reflection and reception is stable. When it is blocked, it is possible to reliably detect the presence of a vehicle and to install the mirror reflection type detectors and reflection mirrors for the number of parking rows on the boarding surface. However, it is simple and costs can be reduced.

Further, according to the present invention, the vehicle presence detecting device for a parking facility according to the second aspect of the present invention forms a diagonal shape with the mirror reflection type detector upward and the reflection mirror downward in a side view of the passenger compartment. With this arrangement, it is possible to prevent the mirror reflection type detector from being contaminated by exhaust gas or dust and from being damaged by the user, and to stabilize the reflection and light reception, thereby enabling more reliable vehicle detection.
