[Embodiment] FIGS. 1 to 4 show a first embodiment. As shown in FIG. 2, this embodiment comprises four units 1 to 4 arranged in the lateral direction, and each of the units 1 to 4 has an upper stage, a middle stage and a lower stage pedestal. Less than,
Each support unit of each unit 1 to 4 is, for example, 1U when instructing the upper one of the first unit, 1F when instructing the middle one, and 1D when instructing the lower one. The suffix "U" is attached to the reference numeral, and the suffix "F" is attached to the middle one and the suffix "D" is attached to the lower one.

When mounting a vehicle on each of the supports 1U to 4D, each of the upper supports 1U to 4U descends to the floor surface 6, mounts the vehicle, and then rises again. The middle pedestals 1F to 4F traverse in one direction, mount the vehicle, and then traverse in the opposite direction again. Further, each of the lower stage supports 1D to 4D rises to the floor surface, mounts the vehicle, and then descends again. Such control of each of the supports 1U to 4D is performed by the multi-level parking apparatus control panel 10 in accordance with a control signal generated by an operator operating the operation panel 8 shown in FIG.

In-vehicle detection means for each of the supports 1U to 4D,
That is, vehicle presence detectors 121U to 124D are provided, respectively. These in-vehicle detectors 121U to 124D are not provided on the support bases 1U to 4D as shown in FIG. 3, but are provided on the wall surface behind them, and the vehicle is present on each support base. A signal indicating whether or not it is supplied to the control means, that is, the inventory detection control board 13.

These inventory detectors 121 to 124D are reflection type photoelectric switches having a light projecting section 14 and a light receiving section 16 as shown in FIG. 4, for example. That is, the light projecting unit 14 projects light on the corresponding support base in accordance with the oscillation signal from the oscillating unit 18, the reflected light is received by the receiving unit 16, and the receiving unit 16 converts the reflected light into the reflected light. Accordingly, a signal indicating whether or not a vehicle is present on the corresponding support is generated. This signal is amplified by the amplifying unit 20 and then supplied to the output unit 22, and the output unit 22 closes the output contact 24 when the receiving unit 16 detects the vehicle. The light projecting unit 14
It is also possible to use a transmission type photoelectric switch that closes the output contact 24 by judging that a vehicle is present on the support table when the light from the light source does not reach the light receiving section 16.

Further, different addresses are assigned to the vehicle presence detectors 121 to 124D, respectively, which are set in the switch unit 26 configured by, for example, a digital switch. The in-vehicle detection control panel 13 is a signal line commonly laid for each of the in-vehicle detectors 121U to 124D, for example, an address signal assigned to each of the in-vehicle detectors 121U to 124D via the address line 28. Are sequentially supplied. This address signal has noise removed by the optical isolation unit 30,
It is supplied to the match detection unit 32. The address signal from the switch unit 26 is also supplied to the coincidence detecting unit 32, and the coincidence detecting unit 32 generates an output signal when both address signals coincide. The coincidence detection unit 32 is an in-vehicle detection control panel.
When a strobe signal is supplied from 13 through the strobe line 34 and the optical isolation section 30, both address signals are compared.

When the two address signals match, the output signal generated by the match detection unit 32 is supplied to the base of the switching transistor 36. The collector of the switching transistor 36 is grounded, and the emitter is connected via a diode 38 to a signal line commonly laid for the presence detectors 121U to 124D, for example, an enable line 40, and an output contact 24 and Each in-vehicle detector 121U to 12U via the diode 42
Signal lines commonly laid for 4D, such as output signal lines
Connected to 44. Enable line 40 and output signal line 44
A voltage of an appropriate value is applied to the vehicle detection control panel 13. Therefore, when the address signal supplied from the presence detection control panel 13 and the address signal set in the switch unit 26 match and the match detection unit 32 generates an output signal, the switching transistor 36 turns on and the enable signal is enabled. line
A current flows from 40 through the diode 38 and the switching transistor 36, the enable line 40 becomes the ground potential, and it is detected that the presence detector corresponding to the address generated by the presence detection control panel 13 responds. Notify the control panel 13.
At this time, when the vehicle is present on the support table monitored by the vehicle presence detector and the output contact 24 is closed, the output signal line 44 passes through the diode 42, the output contact 24 and the switching transistor 36. Current flows, the output signal line 44 becomes the ground potential, and the in-vehicle detection control panel 13 is informed that the in-vehicle detection controller corresponding to the address generated by the in-vehicle detection control panel 13 detects the vehicle. . If the in-vehicle detector does not detect the vehicle and the output contact 24 remains open, the potential of the output line 44 does not become the ground potential, and the in-vehicle detection control panel 13 activates the enable line 40. Although the output line 44 is not at the ground potential,
The occupancy detection control panel 13 knows that the occupancy detector corresponding to the address generated by the occupancy detection control panel 13 does not detect the vehicle.

It should be noted that each of the in-vehicle detectors 121U to 124D is operated by the electric power supplied from the signal line laid in common to them, for example, the power supply line 46 to the power supply unit 48.

In this way, the presence detection control panel 13 is sequentially supplied with signals indicating whether or not a vehicle is present on each of the supports 1U to 4D from the presence detectors 121U to 124D, and based on these signals. Then, the display means, that is, the in-vehicle display panel 50 displays which of the supports the vehicle is on. However, when the support base is operating, each of the in-vehicle detectors 121U to 12U is detected.
Since 4D is not provided on the supporting bases 1U to 4D, the vehicle was detected before the supporting base was activated.However, when the supporting base is activated, the vehicle is no longer detected, or on the contrary, the vehicle is detected. It did not, but because it starts to detect, if the detection result of each in-vehicle detector is displayed as it is when the support base is operating, it is possible to display the accurate in-vehicle state. Can not. Therefore, when the support base is activated, the holding signal is supplied from the multi-level parking device control panel 10 to the vehicle detection control panel 13, and when the holding signal is supplied,
The in-vehicle detection control panel 13 is configured to display the in-vehicle state immediately before the support base operates on the in-vehicle display panel 50.

The second embodiment is shown in FIG. In the first embodiment, different addresses are assigned to the vehicle detectors 121U to 124D, and the vehicle detection control panel 13 sequentially generates address signals, and the vehicle detectors corresponding to the generated addresses are
A signal indicating whether or not a vehicle is present is provided to each of the in-vehicle detectors 12
In contrast to the configuration in which it is supplied to the vehicle detection control panel 13 via the output signal line 44 laid in common to 1U to 124D, the second
In the embodiment, a signal indicating whether or not a vehicle is present is configured to be supplied to the in-vehicle detection control panel 13 via an output signal line provided individually in each of the in-vehicle detectors 121U to 124D. I am doing it. The other points are the same as those of the first embodiment, and detailed description thereof will be omitted.

A third embodiment is shown in FIGS. 6 to 9. In the first and second embodiments, presence detectors 121U to 124D are provided for the respective supports 1U to 4D, whereas in this embodiment, as shown in FIG. 7 and FIG. The in-vehicle detectors 121 to 124 are provided in each unit 1 for each 4 so that it can detect whether or not the vehicle exists at a position where the vehicle can enter and leave, that is, on a support table that is on the same horizontal plane as the floor 6. It is located in. The configurations of these in-vehicle detectors 121 to 124 are the same as those of the in-vehicle detectors 121U to 124D of the first embodiment. Therefore, every time the vehicle detection control panel 13 generates an address signal, the vehicle detection detector corresponding to the address supplies the vehicle detection control panel 13 with a signal indicating whether or not a vehicle is present.

However, with this, it is possible to detect whether or not a vehicle is present on the support platform that is in a position where it can be loaded and unloaded, but which support platform is actually the support platform that is detected whether or not there is a vehicle. I can't tell if it exists. Therefore, in this embodiment, from the three-dimensional parking apparatus control panel 10, each of the supporting stands 1U to 1D is
Is supplied with a status signal indicating the current status of the. This status signal shows that the support base 1U is descending to the floor surface 6 as shown in FIG. 9 (a), and the support base 1D is rising to the floor surface 6 as shown in FIG. 9 (b). State, the state in which the support base 2U is lowered to the floor surface 6 as shown in FIG. 7C, and the state in which the support base 2D is raised to the floor surface 6 as shown in FIG. The state in which the support base 3U is descending to the floor surface 6 as shown in FIG. 6E, the state in which the support base 3D is rising to the floor surface 6 as shown in FIG. 8), there are signals indicating eight states in which the support base 4U is lowered to the floor surface 6 and the support base 4D is raised to the floor surface 6 as shown in FIG.

Based on these status signals, the in-vehicle detection control panel 13
Determines a support base that exists on the same horizontal plane as each floor surface 6, and based on this and the output signals from the presence detectors 121 to 124, the presence of the vehicle on any support base. The presence display is displayed on the in-vehicle display panel 50. Even in this embodiment, when the support base is operating, the vehicle detection control panel 13 displays the vehicle presence state immediately before the support base is activated based on the holding signal from the multi-level parking device control panel 10. .

In each of the above-described embodiments, each unit is composed of the upper, middle, and lower three stages in total, but one unit may be composed of at least two stages.
Further, in the third embodiment, like the first embodiment, every time an address signal is supplied from the in-vehicle detection control panel 13, the corresponding in-vehicle detector outputs a signal indicating whether or not the vehicle is in-vehicle. Although it is configured to supply to the intelligent control panel 13 via a common output line, similarly to the second embodiment, a signal indicating the presence or absence of a vehicle is separately provided from each in-vehicle detector via an output line. The vehicle detection control panel 13 may be configured to be supplied. Further, in each of the above-mentioned embodiments, the photoelectric switch is used as the in-vehicle detector, but an ultrasonic detector or the like may be used instead.

[Effect of the Invention] According to the invention of claim 1, the address for calling each in-vehicle detecting means from the control means, and the signal indicating the presence / absence of an in-vehicle from each in-vehicle detecting means, is detected in each in-vehicle detecting means. Since it is transmitted via a common signal line, it is not necessary to wire between each in-vehicle detection means and the control means, and wiring work is facilitated. Also, even when adding a parking unit,
Since it is only necessary to extend the signal line, add the in-vehicle detection means by the number of the increased supports, and connect these extended in-vehicle detection means to the extended signal line, the extension work becomes easy.
Further, the control means does not have to be manufactured for each of the three-dimensional parking apparatuses having different numbers of supports, and a common one can be used regardless of the place installed.

According to the second or third aspect of the present invention, when the support base is in operation, it is configured to display the in-vehicle status of the support base immediately before the support base operates, so that the support base operates. It is possible to prevent the presence of the vehicle from being erroneously displayed due to the presence of the vehicle. That is, since the structure for detecting the presence status of each support base by the presence detection means provided at a position apart from each support base is adopted, it is simply based on the signal obtained from each presence detection means. When the display is performed, the vehicle presence detection means may monitor a support platform different from the support platform that has been detected so far. There is a possibility of displaying the situation, that is, an erroneous display, but since the display is fixed to the display just before the operation of the support base, it is not erroneously displayed.

According to the invention described in claim 4, since the vehicle presence detecting means is arranged only at a position where it is possible to detect whether or not the vehicle is present at the position where the vehicle in and out of each unit is loaded and unloaded, all the support bases are provided. There is no need to provide vehicle detection means,
It is possible to reduce the total number of vehicle detection means used.

According to the fifth aspect of the present invention, each in-vehicle detection means transmits the detection result of the support table in charge to the control means only when the address supplied from the control means matches its own address. The means can accurately receive the detection result of each in-vehicle detection means.

Further, according to the invention described in claim 6, as in the invention described in claim 2 or 3, it is possible to prevent the occupancy status from being erroneously displayed due to the operation of the support base.
