Abstract

PURPOSE:To surely receive a car without indications of a supervisor by providing a selecting means which indicates a parking device of such size as to correspond to the size of a car in response to a sensing signal of car size. CONSTITUTION:As soon as a car enters a gate 3, the width of the car is sensed by each photoelectric sensor and outputted to a CPU 40, and, for example, it is judged that the width of the car is within the interval between a first light emitter 8c and a third light emitter 12c. In a similar manner, the CPU 40 judges that the length of the car is within the interval between a second light emitter 10 and a fifth light emitter 15i. And the height of the car is judged by a sixth light emitter, and at the same time, the weight of the car is measured by a weighing machine 31. The CPU 40 selects one of multistory parking spaces S, M, L of different sizes from data, i.e., width, length, height, weight of the car and displays the selected space on an electric displayer 5 and at the same time reports it by means of a speaker 6b. And if the weight exceeds safety standards of the multistory parking space S, the multistory parking space M one size above the space S is indicated.

A weight scale 31 for measuring the weight of the vehicle is arranged on the lower surface of the floor F.

Next, the electrical structure of the main part of the parking lot 1 of the first embodiment will be described with reference to FIG. A central processing unit (hereinafter referred to as a CPU) 40, which is a selection unit, has a memory 41, an electronic display panel 5, a stop lamp 6a, and a speaker 6.
b, each light receiver 9, 11, 13, 16, 17, 19, 2
3, the weight scale 31 and the multilevel parking devices S, M, and L are connected. The CPU 40 is arranged in a control panel (not shown) in the manager's room 2, controls the operation of the entire device based on a program stored in the memory 41, and checks the warehousing status of the multilevel parking devices S, M, L. To do. In the memory 41, each light receiver 9, 11, 13, 16, 17, 19, 23, 2 is received.
Eight position data are programmed.

If the vehicle has any of the light receivers 9, 11, 13,
When the light projection is blocked by crossing 16, 17, 19, 23, 28, the light receivers 9, 11, 13, 16, 17,
19, 23 and 28 detect it and send a detection signal to the CPU 4
Output to 0. In addition, the weighing scale 31 outputs the weight data of the vehicle C to the CPU 40. The CPU 40 determines the width, length, height and weight of the vehicle based on the detection signal, the weight data and the like. Then, it is determined which of the three-dimensional parking apparatuses S, M, L the parking apparatus should be stored in, and the drive signal is output to the electronic display panel 5 to determine the three-dimensional parking apparatus S,
The M and L are electronically displayed. Meanwhile, the second
When the emission of light to the light receiver 11 is blocked, the CPU 40 outputs a drive signal to the lamp 6a and the speaker 6b based on the detection signal.

Next, the operation of the parking lot 1 according to this embodiment will be described. Entrance side passage E to use parking lot 1
When the vehicle C that has entered the vehicle enters the inside of the gate 3, the vehicle C proceeds at a slow speed. Then, when the front side of the vehicle C blocks the light projection from the second light projector 10, the second light receiver 1
1 detects this and a detection signal is output to the CPU 40. The CPU 40 drives the vehicle stop system 5b based on the detection signal, blinks the vehicle stop lamp 6a, and causes the speaker 6b to announce "Please stop".

On the other hand, at the same time when the vehicle C gets into the gate 3, the size of the vehicle C is detected by each photoelectric sensor, and the detection signal is output to the CPU 40. As shown in FIG.
For example, looking at the case of detecting the width of the vehicle C, the vehicle C
The first floodlight 8 closer to the center of the gate 3 by the right side surface of the
Even from the a to the light projection of the seventh light projector 24b is blocked in order, but the following light projection of the first light projector 8c is not blocked.
On the left side surface of the vehicle C, the projection of the eighth light projector 29b is blocked, but the projection of the adjacent third light projector 12c is not blocked. Therefore, the CPU 40 is
The vehicle width is determined to be within the interval between the first light projector 8c (seventh light receiver 23c) and the third light projector 12c (eighth light receiver 28c).

Similarly, in the case of detecting the length of the vehicle C,
It suffices to detect the position of the rear end of the vehicle C at the moment when the front end of the vehicle C blocks the light projected from the second light projector 10. That is,
It is determined that the length of the vehicle C is the length between the second light projector 10 and any of the intervals between the fourth light projectors 14a to 14j to the fifth light projectors 15a to 15j. For example, as shown in FIG. 3, the vehicle C blocks the light emitted from the second light projector 10. In this state, the rear side of the vehicle C is the fourth light projector 14h in order from the fifth light projector 15a near the center of the gate 3.
Is blocked, but the following fifth projector 15i is blocked.
Is not blocked. Therefore, the CPU 40 changes the vehicle length of the vehicle C to the second projector 10 (second light receiver 11).
And the fifth light projector 15i (fourth light receiver 16i).

When the height of the vehicle C is detected,
For example, if the vehicle C has two of the sixth projectors 18a to 18c,
Suppose that the second projector 18b is blocked. Then C
The PU 40 determines that the height of the vehicle C is within the light projector 18a. At the same time, when the vehicle C gets on the floor F, the weight of the vehicle is measured by the weight scale 31 and output to the CPU 40.

The CPU 40 uses the data of the width, length, height, and weight of the vehicle C to obtain three-dimensional parking apparatuses S of three sizes.
Judge which of M and L should be stored,
The judgment result is displayed on the electronic display panel 5 and the speaker 6
Notify by b. Here, for example, even if the width, the length, and the height are compatible with the multilevel parking apparatus S, the weight is the multilevel parking apparatus S.
If the safety standard is not less than the above, a multi-level parking device one size up is specified. For example, when the vehicle is to be stored in the multi-level parking device M, the letter M in the display of S, M, and L is made to blink, and the speaker 6b informs that "Please insert the car from the central parking opening". The driver confirms the electronic display panel 5 and hears the announcement, and then advances the vehicle C again to enter the instructed parking apparatus M.

Further, the CPU 40 determines which of the three-dimensional parking devices S, M, and M from the data of the width, length, height and weight of the vehicle C.
When it is determined that it does not fit in the L parking size, the speaker 6b is informed that "Your car cannot be parked in this parking lot".

Further, the CPU 40 originally determined that the size of the vehicle C is the multi-level parking apparatus S, but when the multi-level parking apparatus S is full, an instruction to store the vehicle in the multi-level parking apparatus M one size up is given instead. If the multi-story parking apparatus M is full, the multi-story parking apparatus L is similarly instructed to be stored. Although it was originally determined that the size of the vehicle C is the three-dimensional parking apparatus M, when the three-dimensional parking apparatus M is full, the electronic display panel 5 and the speaker 6 are arranged so that the vehicle can be stored in the three-dimensional parking apparatus L.
It is designed to instruct b. That is, when the vehicle is full, the multilevel parking devices M, L having a size larger than the compatible size
Will be selected.

With this structure, the following effects can be obtained. 1) The administrator does not need to check the size of the vehicle C one by one, the burden on the administrator is reduced, and the photoelectric sensor 8
The size of the vehicle C can be instantly determined by 19, 23, 24, 28 and 29, which speeds up the parking work. Also,
There is no mistake about grasping the size because even if it is a special size vehicle such as a so-called one-box car or a foreign car and the size cannot be recognized enough at first glance, it is not visually recognized by humans. . In addition, since it is immediately known whether or not the vehicle size is unparkable, it is not necessary to test whether or not the vehicle can be parked.

2) Each photoelectric sensor 8-19, 23, 24,
Numerals 28 and 29 are formed by arranging a light emitter and a light receiver so as to face each other. For example, in the reflection type in which the light is reflected by the mirror on the same side as the light projector and the light receiver, there is a possibility that the light is reflected by the vehicle C and malfunctions occur, but in the case of the embodiment, it does not malfunction.

3) The electronic display panel 5 or the speaker 6b can surely indicate to the driver the three-dimensional parking apparatus S, M, L to be stored. Further, since the instruction is given by both the electronic display panel 5 and the speaker 6b, the three-dimensional parking apparatus S, M, L to be stored will not be mistaken even if the electronic display panel 5 is not seen or the announcement is missed.

4) By temporarily stopping, the size of the vehicle C can be measured more accurately, and after the size of the vehicle C is measured, the driver can safely check the electronic display panel 5 and announcements in a stopped state, and immediately after confirmation Multi-level parking device S,
It is possible to proceed to M and L. Therefore, the driver is not confused, and the predetermined multi-level parking devices S, M,
Can be stored in L.

5) Even if the small-sized three-dimensional parking devices S, M, etc. are full, the CPU 40 automatically selects the one-sized three-dimensional parking devices M, L so that the electronic display panel 5 and the speaker 6b can be selected. Since the instruction is given, there is no possibility that the vehicle cannot be parked even though the vehicle can be parked.

6) Seventh and eighth light receivers 23a-23c, 28a-28c and seventh and eighth light projectors 24a-24c, 29a-29c are provided in the grooves 20, 25. Since these photoelectric sensors are covered with the top plates 21 and 26, the accuracy of the sensors will not be deteriorated due to dust clogging. For dust and dirt, the grooves 20 and 25 are the grooves 2.
Since it is deposited below 0 and 25, it does not interfere with the detection of the photoelectric sensor.

Although the embodiment of the parking lot 1 of the present invention has been described above, the present invention can be carried out by changing to other modes as follows. In the above embodiment, each photoelectric sensor 8 to 19, 23, 24,
28 and 29 are arranged so that the light projector and the light receiver are separate bodies and face each other, but they do not necessarily have to face each other. The light emitter and the light receiver may be arranged on the same side and reflected by a reflecting mirror. Further, the light projector and the light receiver may be integrated. Also,
Although the light emitters and the light receivers are alternately arranged, they need not necessarily be alternately arranged.

Both the electronic display board 5 and the speaker 6b are not necessarily required. This is because it is possible to instruct the driver in either direction. Moreover, you may change to a notification buzzer instead of the speaker 6b.

In the above embodiment, the photoelectric sensors 8 to 19,
Although 23, 24, 28, and 29 are arranged in the gate 2, the arrangement position is not particularly limited. Also, the grooves 20, 2
Although the groove 5 is formed, the riding portion 32 having a triangular cross-section as shown in FIG. 7 may be used instead of the grooves 20 and 25. A protection plate 33 is provided on the upper surface of the riding portion 32 to prevent the tires of the vehicle C from hitting the sensors 23a to 23d.
Is installed.

In the above embodiment, the multi-story parking systems S, M, L
It was a parking lot 1 equipped with. However, the parking device does not have to be a multilevel parking device. Further, in the embodiment, there are three types of multilevel parking devices S, M, and L, but two types may be used and four types.
It doesn't matter if more than one kind.

In the above embodiment, the width, length and height of the vehicle C are detected in 50 mm increments. However, the detection may be performed at intervals less than 50 mm, or may be detected at intervals greater than 50 mm. Moreover, each photoelectric sensor 8-19, 2
It is also free to change the number of 3, 24, 28, 29. In addition, the present invention can be freely modified and implemented without departing from the spirit of the present invention.

Other technical ideas grasped by the above embodiments will be described below along with their effects. (1) As a selecting means of the configuration of the invention of claim 1, if there is no parking device of a size that responds to the selection of a parking facility according to the detected vehicle size and there is no response, an informing means (for example, the above implementation) In the example, add speaker 6b). This way, you can immediately see the size of a vehicle that cannot be parked, so you do not have to test whether you can park.

(2) As the selection means of the configuration of the invention of claim 1, stop instruction means for instructing the stop of the vehicle (for example, the stop lamp 6a, the speaker 6b in the above embodiment) is added. By doing so, the size of the vehicle can be measured more accurately, and the driver can safely confirm the display means such as the electronic display panel 5 after measuring the vehicle size.

(3) As a selection means of the configuration of the invention of claim 1, when the parking device responding to the detected vehicle size is full, a parking device having a larger empty space is selected. In this way, the situation in which parking is not possible even though parking is possible does not occur.
