Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for detecting on which support stand a vehicle is present in a multi-story parking system.

[Prior Art] Conventionally, as a vehicle presence detection device in the above-mentioned multilevel parking system, there is a vehicle presence detection device such as that disclosed in Japanese Utility Model Publication No. 56-2762, for example. This means that a wheel support plate is arranged at at least one wheel position on the support stand so that the switch is not normally activated by spring force, and when the wheel is placed on this wheel support plate, the spring force is applied to the wheel support plate. It is a mechanical type that operates the switch by rotating against the One of these vehicle presence detectors is installed on each support stand, and each of these vehicle presence detectors is individually wired to a vehicle presence detection control panel, and the vehicle presence detection control panel receives the output signal from each vehicle presence detector. was displayed as is on the display panel.

[Issue 8 to be solved by the invention] However, since this type of vehicle presence detection device uses a mechanical vehicle presence detector, it may not work if used for a long period of time. There is a problem with instability. Furthermore, since the vehicle presence detector must be provided on the support base, there is a problem in that the support base must have a special structure that allows the vehicle presence detector to be provided. In addition, since the vehicle presence detector is installed on a support stand, when the support stand is lowered, the wiring from the vehicle presence detector to the vehicle presence detection control panel may get caught on a vehicle or the like and be disconnected. There was also the problem that it was easy to use.

The present invention has stable operation even when used for a long period of time, can use a normal support stand, and is r! It is an object of the present invention to provide a vehicle presence detection device for a multilevel parking system in which R lines are less likely to occur.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the first invention includes a system in which a plurality of units in which at least two support stands are arranged to be vertically movable are arranged in a horizontal direction. The multi-level parking system includes a plurality of vehicle presence detection means, a display means, and a plurality of vehicle presence detection means, each of which is provided at a position apart from each of the support stands and detects whether or not a vehicle is present on each of the corresponding support stands. The present invention includes a control means for causing the display means to display the vehicle presence status on each support stand based on the output signal from the vehicle detection means.

Moreover, the second invention is the above-mentioned multilevel parking device,
A plurality of vehicle presence detection means, which are provided at a distance from each support stand located at a position where vehicles can enter and exit each unit, and detect whether or not a vehicle is present on these support stands; and a display means; , control means for causing the display means to display the vehicle presence status of each of the support stands in accordance with the output signal from each vehicle presence detection means and the current up/down state of each support stand.

Further, in the:51 or second invention, addresses of different values are set for each vehicle presence detection means, and the control means is configured to sequentially output addresses of different values to each vehicle presence detection means. However, each vehicle presence detection means may be configured to supply a signal indicating the presence or absence of a vehicle to the control means when the address supplied from the control means matches an address set for itself.

Further, in the first or second aspect of the invention, the control means may be configured to display the vehicle presence state immediately before the operation on the display means when any one of the support stands is activated. Ru.

[Operations] According to the first invention, a signal indicating whether a vehicle is present on either the vehicle presence detection means or each support stand is supplied to the control means.

Based on these signals, the control means displays which of the supports the vehicle is located on.

The most distinctive feature of the first invention is that the electronic vehicle presence detection means is not provided directly on the support base.

According to the second invention, each vehicle presence detection means supplies the control means with a signal representing the presence or absence of a vehicle on each support stand that is located at a position in each unit where a vehicle can enter and leave the warehouse. However, from this signal level, it is unclear which support stand is located at a position where the vehicle can enter and exit the warehouse. Therefore, based on the current elevation status of each support stand, it is determined which support stand is located at a position where storage can be taken in and out. Depending on the presence or absence of a vehicle, a display means displays which of the support stands the vehicle is present on.

Further, addresses of different values are set for each vehicle presence detection means, and the control means is configured to sequentially output addresses of different values to each vehicle presence detection means, so that each vehicle presence detection means is supplied with addresses of different values from the control means. If the vehicle is configured to supply a signal indicating the presence or absence of a vehicle to the control means when the specified address matches the address set for itself, the wiring between each vehicle presence detection means and the control means can be simplified. .

Furthermore, if the control means is configured to display the vehicle presence state immediately before the operation of any of the supports when one of the supports is in operation, the display means may be configured to display the vehicle presence state immediately before the operation of the support, which may result in an inaccurate display while the support is in operation. This prevents the display of vehicle presence status.

[Example] A first example is shown in FIGS. 1 to 4. As shown in FIG. 4, this embodiment consists of four units 1 to 4 arranged in the horizontal direction, and each unit 1 to 4 has an upper stage, a middle stage, and a lower stage support stand, respectively. Hereinafter, each support stand of each unit 1 to 4 will be designated as 1, for example, IU will be used to designate the upper part of the first unit, IF will be used to designate the middle part of the first unit, ID will be used to designate the lower part of the first unit, and so on. Each unit is indicated by a suffix U for the upper row, F for the middle row, and D for the lower row.

When placing a vehicle on each of the support stands tU to 4D, each of the upper support stands IU to 4U descends to the floor 6, places the vehicle thereon, and then rises again. The middle support stands IF to 4F traverse in one direction, place a vehicle thereon, and then traverse again in the opposite direction.

Furthermore, each of the lower support stands ID to 4D rises to the floor surface, places the vehicle thereon, and then lowers again. Such control of each of the support stands 1U to 4D is performed by the multilevel parking system control panel IO in response to control signals generated by an operator operating the operation panel 8 shown in FIG.

Vehicle presence detection means, that is, vehicle presence detectors tztu to 124D, are provided for each of the support stands IU to 4D, respectively. These vehicle presence detectors 1211J to 12
40 is not provided on each support stand 1u to 4D as shown in FIG. 3, but is provided on the wall behind them,
A signal indicating whether or not a vehicle is present on each support platform is supplied to the control means, that is, the vehicle presence detection control panel 13.

These vehicle presence detectors 1210 to 1240 are, for example, the fourth
As shown in the figure, it is a reflective photoelectric switch having a light projecting section 14 and a light receiving section 16. That is, the light projecting section 14 is the oscillating section 1
In response to the oscillation signal from 8, light is projected onto the corresponding support base, and the reflected light is received by the receiver 16.
generates a signal indicating whether or not a vehicle is present on the corresponding support base in accordance with the reflected light. After this signal is amplified by the amplifier ZO.

The signal is supplied to the output section 22, and the output section 22 closes the output contact 24 when the receiving section 16 detects a vehicle. Incidentally, when the light from the light projecting section 14 does not reach the light receiving section (6), it may be determined that a vehicle is present on the support base, and the output contact 24 may be closed as a transmission type photoelectric switch.

In addition, different addresses are assigned to the six vehicle presence detectors 121LI to 124D, and these addresses are set in the switch section 26 configured by, for example, a digital switch. The vehicle presence detection control panel 13 includes a famous vehicle detector 1.
The temporary addresses assigned to these detectors 121U to 124D are sequentially supplied to the famous flower wheel detectors 121U to 124D via an address line 28 that is installed in common to 21U to 124D. This address signal has noise removed by the optical isolation section 30 and is supplied to the coincidence detection section 32 . This coincidence detection section 32 is also supplied with an address signal from the switch section 26, and this coincidence detection section 32 generates an output signal when both address signals match. Note that the coincidence detection unit 32 connects the strobe line 3 from the vehicle presence detection control panel 13.
4. Compare both address signals when the strobe signal is supplied via the optical isolation section 30.

When both address signals match, the output signal generated by the match detection section is supplied to the base of the switching transistor 36. The collector of this switching transistor 36 is grounded, and the output terminal is connected via a diode 38 to an enable line 40 that is common to the flower wheel detectors 121tl to 1241), and the output contact 24 and the diode 42. 6 vehicle presence detector 12 via
It is connected to an output signal line 44 laid in common for 10 to 124D. A voltage of an appropriate value is applied to the enable line 40 and the output signal line 44 from the vehicle presence detection control panel 13. Therefore, when the address signal supplied from the vehicle presence detection control panel 13 and the address signal set in the switch section 26 match and the coincidence detection section 32 generates an output signal, the switching transistor 36 is turned on.

A current flows from the enable line 40 through the tie auto 38 and the switching transistor 36, and the enable line 40
becomes the ground potential, and notifies the vehicle presence detection control board 13 that the vehicle presence detection control board 13 is responding to the vehicle presence detector corresponding to the generated address. At this time, if there is a vehicle on the support platform being monitored by this vehicle presence detector, the output contact 2
4 is closed, the output signal &! A current flows from a44 through the diode 42, the output contact 24, and the switching transistor 36, and the output signal line 44 becomes the ground potential, and the vehicle presence detector corresponding to the address generated by the vehicle presence detector 1g113 detects a vehicle. The presence of the vehicle is notified to the vehicle presence detection control panel 13. If this vehicle presence detector does not detect a vehicle and the output contact 24 remains open, the potential of the output line 44 will not reach the ground potential, and the vehicle presence detection control panel 1'l will be enabled. Even though line 40 is at ground potential, output line 44 is not at ground potential, so the vehicle presence detector @1fl13 or the vehicle presence detector corresponding to the generated address is not detecting the vehicle. The vehicle presence detection control panel 13 knows that there is no vehicle.

Note that the famous flower wheel detectors 121U to +24D are operated by power supplied to the power supply unit 48 from a power line 46 installed in common to these detectors.

In this way, each support stand I is attached to the vehicle presence detector 04 panel 13.
Signals indicating whether or not a vehicle is present on U to 4D are sequentially supplied from the flower car detectors 121U to 24D, and based on these signals, the display means, that is, the vehicle presence display panel 5D shows which support stand is present. Displays whether the vehicle is being cut or not. However, when the support stand is in operation, the vehicle detectors 121U to 124D are not installed on the support stands IU to 4D, so the vehicle was detected before the support stand was activated. , Vehicles may not be detected due to the operation of the support stand, or conversely, vehicles may not be detected but will now be detected, so when the support stand is operating, each vehicle presence detector If the detection results are displayed as they are, it is not possible to accurately display the vehicle presence status. Therefore, when the support base is activated, the multilevel parking system control panel 1
A holding signal is supplied from 0 to the vehicle presence detection control panel 13, and when this holding signal is supplied, the vehicle presence detection control panel 13 displays the vehicle presence state on the vehicle presence display panel 5 immediately before the support platform operates.
It is configured to display 0.

A second embodiment is shown in FIG. In the first embodiment, different addresses are assigned to the six vehicle presence detectors 1210 to 124D, and address signals are sequentially generated from the vehicle presence detection system@board 13, and the vehicle presence detector corresponding to the generated address is selected. , a signal indicating whether or not a vehicle is present is supplied to the vehicle presence detection control panel 13 via an output signal line 44 commonly installed in the four vehicle presence detectors +210 to 124D. , in the second embodiment, six vehicle presence detectors 121
A signal indicating whether or not a vehicle is present is sent to the vehicle presence detector m via output signal lines provided individually from 0 to 124D.
It is configured to be supplied to q113. Other points are configured similarly to the first embodiment, so detailed explanation will be omitted.

A third embodiment is shown in FIGS. 6 to 9. 1st and 2nd
In this embodiment, vehicle presence detectors 121U to 124D were provided for each of the support stands 10 to 4D, whereas in this embodiment, as shown in FIGS. 7 and 8, vehicles enter and leave the warehouse. Vehicle presence detectors 121 to 124 are arranged for each unit 1 to 4 to detect whether or not a vehicle is present on a support stand located at a position where the vehicle can be detected, that is, on the same horizontal plane as the floor surface 6. . The configurations of these vehicle presence detectors 121 to 124 are the same as the vehicle presence detectors 121υ to 124D of the first embodiment. Therefore, every time the vehicle presence detection control panel 13 generates an address signal, the vehicle presence detector corresponding to that address supplies a signal indicating whether or not a vehicle is present to the vehicle presence detection control panel 13.

However, with this method, is it possible to detect whether or not there is a vehicle on the support platform in a position where it can enter and exit the warehouse? It is not possible to determine whether Therefore, in this embodiment, a status signal indicating the current state of each support stand IU to ID is supplied from the multilevel parking apparatus control panel 10. This status signal includes a state in which the support stand 1u is lowered to the floor surface 6 as shown in FIG.
As shown in Figure (C), the support stand 2u has been lowered to the floor level 6. As shown in Figure (d), the support stand 2U has risen to the floor level 6. The state in which the support stand 3U is lowered to the floor 6 as shown in (e) of the same figure, the state in which the support stand 3U is lowered to the floor 6 as shown in the same figure (')
The support stand 4U is lowered to the floor 6 as shown in (g) of the same figure, and the support stand 4D is raised to the floor 6 as shown in (h) of the same figure. There are signals representing eight states.

Based on these status signals, the vehicle presence detection control panel 13
determines the support stands existing on the same horizontal plane as each floor surface 6, and based on this and the output signals from the flower car detectors 121 to 124, determines whether a vehicle is present on any support stand -L. Whether there is a vehicle or not is displayed on the vehicle presence display panel 50. In this embodiment as well, while the support platform is in operation, the vehicle presence detection control panel 13 displays the vehicle presence state immediately before the support platform is activated based on the holding signal from the multilevel parking system control panel 10. let

In each of the above embodiments, each unit is composed of a total of three stages of support stands: an upper stage, a middle stage, and a lower stage. However, one unit may be composed of at least two stages of support stands. In this embodiment, vehicle presence detection control is performed in the same way as in the first embodiment! ! ! 113, the corresponding vehicle presence detector supplies a signal indicating the presence or absence of a vehicle to the vehicle presence detection control panel 13 via a common output line. Vehicle presence detection is controlled via an output line that is individually provided with a signal indicating the presence or absence of a vehicle from each vehicle presence detector, just like in the embodiment! ! 113. Further, in each of the above embodiments, a photoelectric switch is used as the vehicle presence detector, but an ultrasonic detector or the like may be used instead.

[Effects of the Invention] According to the invention described in claims 1 to 6, since the vehicle presence detector for detecting whether a vehicle is placed on each support platform is not provided on the support platform, the detector is not installed on the support platform. There is no need to create a special support for installation; a regular support can be used. Furthermore, since there is no need to provide the detector on the support base, there is no need to wire the sensor on the support base, and there is no possibility that the wires will be disconnected due to the entry or exit of the vehicle. Furthermore, since the detector is electronic rather than mechanical, it remains stable even after long-term use.

Further, according to the invention described in claim 2 or 5, different addresses are assigned to the vehicle presence detectors, and the vehicle presence detector corresponding to the address generated from the vehicle presence detection control panel determines whether or not a vehicle is present. Since a configuration is adopted in which a signal representing the vehicle presence is supplied to the vehicle presence detection control panel, there is no need to wire each vehicle presence detector to the vehicle presence detection control panel, making the wiring work easier. Furthermore, when increasing the number of support stands, the currently installed power lines, address lines, strobe lines, and enable lines can be extended, making the expansion work easier.

Further, according to the invention as claimed in claim 3 or 6, when the support stand is in operation, the vehicle presence status of each support stand immediately before the support stand is activated is displayed in response to the holding signal. This prevents the vehicle presence status from being displayed incorrectly due to the support stand being in operation.

Further, according to the invention as claimed in claim 4, since the vehicle presence detector is arranged only at a position where it can detect whether or not a vehicle exists at the position where a vehicle enters and leaves the warehouse in each unit, all the support stands There is no need to provide a vehicle presence detector for the vehicle, and the total number of vehicle presence detectors used can be reduced.
