Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking lot broadcasting system, and more particularly, to store an antenna for a vehicle occupant whose antenna is extended when the vehicle is loaded into a height-limited mechanical parking device. Be involved in calling out measures.

[0002]

2. Description of the Related Art Generally, when a mechanical parking device (for example, a two-tiered parking device) is provided in a part or all of a parking space of a parking lot, in order to improve the accommodation efficiency of a vehicle with respect to the outer size of the parking device. The height of the passenger compartment is kept to the minimum required.

On the other hand, conventionally, as a detection device for detecting an automobile that cannot be put into the entry portion of the mechanical parking device, for example, as disclosed in Japanese Utility Model Laid-Open No. 164557/1985, a vehicle is a mechanical parking device. A plate-like object having a tip (lower end) located at a height position substantially matching the height limit position of the boarding portion is swingably provided in an approach path for getting in the vehicle, and an automobile for the lower end of the plate-like object is provided. It is known to mechanically detect an automobile that cannot be loaded into the loading section by swinging the plate-like object with the base end (upper end) as a fulcrum by the contact of.

Further, as another detection device, a photocell is provided at a height position which substantially coincides with the height limit position of the entry part in the approach road, and a part of the automobile (upper end part) passing in front of the phototube. There is also a system in which the vehicle is caught by the luminous flux emitted by the photoelectric tube and an automobile that cannot be put into the riding section is optically detected.

[0005]

By the way, since the antenna used when listening to the in-vehicle radio is extended to an upper position which is considerably higher than the total height of the vehicle, the antenna is used when the vehicle is loaded into the mechanical parking apparatus. It needs to be stored (contracted). In that case, it suffices if the extension of the antenna is detected by each of the detection devices, but in the mechanical detection device, since the antenna itself is weak in strength, the antenna is contacted with the plate-shaped object. Will be broken when the extension is detected. On the other hand, the optical detection device may not be able to detect because the antenna is thinner than the luminous flux of the photoelectric tube, and the antenna will be broken when the automobile is put into the entry part.

[0006] Therefore, it is conceivable that a broadcasting system, such as a speaker, for a vehicle passenger passing through the approach road will be called to store the antenna when the vehicle is loaded into the mechanical parking apparatus, but the window is closed. For passengers listening to radio music, etc. while in a state, it is necessary to call from the speaker at a fairly large volume. At this large volume, passengers in a car with windows open or getting out of the car On the contrary, it makes noise to passengers. Furthermore, in order to cover the approach road evenly by broadcasting by the speaker, a large number of speakers are required according to the length of the approach road and the scale such as the number of the approach road, and a great cost is spent on the broadcasting system.

The present invention has been made in view of the above points, and it is an object of the present invention to pay attention to the fact that most of the automobiles in the antenna extended state listen to the radio, and to drive the automobiles to the mechanical parking device. By making it possible to broadcast from the radio that calls for the antenna to be stored before it is put in, it is possible to eliminate the large number of speakers, reduce the cost of the broadcasting system, and reliably prevent damage to the antenna of the car while listening to the radio. is there.

[0008]

[Means for Solving the Problems] To achieve the above object, a solution means provided by the invention as set forth in claim 1 is a broadcasting system of a parking lot, which has an approach path for getting a vehicle into a mechanical parking device. A radio wave of a plurality of frequencies including the frequency of the radio broadcast which is provided and is capable of being received at the frequency of the radio broadcast being received by the in-vehicle radio of the car passing through the approach road, and broadcast of contents prompting the antenna to be stored. The configuration is such that a transmitting device for transmitting is provided.

[0009] The solving means taken by the invention of claim 2 is
Of the broadcasts that specify the transmitter of the invention according to claim 1 and restrict the entry of a vehicle into the mechanical parking device, and the broadcasts that guide the occupant after the vehicle is loaded into the mechanical parking device, The configuration is such that at least one of the contents is also broadcast.

It is configured to provide a means for preventing the leakage to the inside.

[0012]

According to the above-mentioned structure, according to the first aspect of the present invention,
When an automobile is moved into the entry path to park in the mechanical parking device while listening to the radio broadcast music from the in-vehicle radio with the antenna extended, the in-vehicle radio of the automobile interferes with radio broadcast waves. However, a broadcast of contents prompting the antenna to be stored is received from a transmitting device that transmits radio waves of a plurality of frequencies including the frequency of the radio broadcast, and the vehicle occupant who receives this broadcast on the radio,
Before the vehicle is loaded into the mechanical parking device, the extension of the antenna is noticed and the antenna is retracted (contracted) in advance. As a result, the occupant of the vehicle before entering the entry section of the mechanical parking system is called upon to store the antenna in the extended state without depending on the speaker broadcast, and the antenna of the vehicle during listening to the radio can be reliably broken. It is also possible to prevent unnecessary calls to the occupants of the vehicle with the antenna retracted.

Moreover, since the radio waves transmitted from the transmitting device are received by the on-vehicle radio of the vehicle passing through the approach road, only one transmitting device is required even if a plurality of approach roads are provided.

According to the second aspect of the present invention, in the case where the transmission device also transmits a broadcast of a content that restricts the entry of an automobile passing through the approach road before entering the entry part of the mechanical parking device. , Such as roof carrier and spoiler are protruding beyond the size of the vehicle,

The car 9 which cannot be parked is limited to the upper tier 8a by 9. On the other hand, the plane parking space 7 is sufficiently secured in the vertical height so that even a car with a high vehicle height such as a one-box type can be parked.

The indoor parking lot 1 is equipped with a transmitter 31 for transmitting radio waves of a plurality of frequencies of AM and FM radio broadcasts that can be received by the radio of each automobile C. The transmitting device 31 is a publicly known device that has already been implemented as a broadcasting system for locally broadcasting in a long distance tunnel or the like. Radio waves can be received by transmitting radio waves of multiple frequencies that can be received at the same frequency. The transmitter 31 is housed in a housing box 32 attached to the lower surface 2a of the building 2,
An ON / OFF switch (not shown) in the manager's room 28 allows the transmitter 31 to repeatedly transmit radio waves when switching ON. From this transmitting device 31, a broadcast radio wave for prompting the storage of the antenna Ca of the automobile C is transmitted, and this transmission radio wave (the circular arc shown by the broken line in FIG. 1) is the three-dimensional space of the mechanical multi-level parking device 13. Before the car C is placed in the parking space 8 (upper 8a and lower 8b), the radio of the car C can be received.
When the vehicle approaches the slope 6 from the entrance 4 of the indoor parking lot 1, it spreads all over the indoor parking lot 1 and can be received by the radio of the car C in the indoor parking lot 1.
In addition, the broadcast signal transmitted from the transmission device 31 is limited in its output so that it can be received by the radio of the car C for the first time when approaching the slope 6 from the entrance 4 of the indoor parking lot 1. By thus limiting the output of the radio wave transmitted from the transmission device 31, a means for preventing the radio wave transmitted from the transmission device 31 from leaking out of the parking space of the indoor parking lot 1 is configured. In this case, the radio waves transmitted from the AM and FM radio stations are blocked by the surrounding wall of the indoor parking lot 1 when the vehicle C enters from the entrance / exit 4 of the indoor parking lot 1 and cannot be received. The radio of the car C receives the radio waves that can be received at the radio broadcast frequencies as they are, that is, the broadcasts from the transmission device 31 that emits radio waves of a plurality of frequencies including the radio broadcast frequencies.

Therefore, in the above embodiment, the antenna C
When a car C is entered from the doorway 4 into the indoor parking lot 1 in order to park in the multi-storey parking space 8 while listening to the radio broadcast music or the like with a being extended, the radio broadcasting station from the radio of the car C emits radio waves. Radio waves of the frequency
An underground closed space surrounded by surrounding walls, such as the indoor parking lot 1, blocks the reception unreachably. At that time, a broadcast from the radio that prompts storage of the antenna Ca from the transmitting device 31 that emits radio waves at a plurality of frequencies that can be received at the respective frequencies of the AM and FM broadcasts including the frequencies of the radio broadcasts. The occupant of the car C who has received this broadcast on the radio notices the extension of the antenna Ca before the car C is placed in the multi-level parking space 8, that is, at the time of approaching the slope 6. It is stored (contracted) in advance. As a result, the occupant of the vehicle C before getting into the entry section 10 (lower stage 8b) of the multi-story parking space 8 is called for to store the antenna Ca in the extended state without depending on the speaker broadcast, and while listening to the radio. It is possible to reliably prevent breakage of the antenna Ca of the vehicle C, and it is possible to prevent an unnecessary call to an occupant of the vehicle C in the state where the antenna Ca is stored.

In addition, the radio wave transmitted from the transmission device 31 is effectively blocked by the closed space such as the underground indoor parking lot 1, and the output of the transmission radio wave is further limited to suppress the radio wave from the transmission device 31. Since it constitutes a means to prevent the vehicle from leaking out of the parking space of the indoor parking lot 1,
It is possible to reliably prevent radio interference from an unrelated car radio outside the outdoor parking lot 1 in combination with the radio wave blocking effect inside the indoor parking lot 1.

Further, since the transmitting device 31 emits radio waves throughout the indoor parking lot 1 when it approaches the slope 6 from the doorway 4 of the indoor parking lot 1, the indoor parking lot is wide and a plurality of doorways are provided. Even if it is provided, only one transmitter is required, and the facility cost of the broadcasting system can be reduced.

When sending together, the mechanical three-dimensional parking of the vehicle such as roof carriers, spoilers, and other additional objects protruding beyond the vehicle's dimensions, or the vehicle height, width, and length exceeding the restrictions of the entry section The entry into the device is avoided in advance, and the damage to not only the automobile (including the additional object) but also the main part of the mechanical multilevel parking device is effectively prevented. In addition, when it takes more time to reach the multi-level parking space from the doorway of the indoor parking lot and the indoor parking lot is provided for the parking lot for the event facility, the broadcast contents of the above embodiment or the above In addition to the broadcast contents that restrict entry, in addition to broadcasting contents that guide passengers after entering a car in a multi-level parking space such as event contents, it may be broadcast together, and the passenger after parking the car in the parking space You will be guided smoothly. In addition, the broadcast of the contents prompting the antenna to be stored by the speaker in the indoor parking lot with the volume turned down to the level that does not make noise for passengers in the car with the windows of the car open and those getting off the car, and to the multi-level parking space A nameplate or the like that prompts the storage of the antenna attached to the entrance may be used together.

Further, in the above embodiment, the car C passing through the approach road 5a of the indoor parking lot 1 is targeted, but the car C passing through the approach road of the outdoor parking lot may be targeted. Further, in the above embodiment, the radio wave from the transmitting device can be received while the radio wave of the radio broadcast cannot be received.However, the radio wave is transmitted to the occupant while interfering with the radio broadcast by transmitting the radio wave. It may be possible to call attention, and in this case, it is possible to prevent radio waves from leaking out of the approach road by giving weak radio waves high directivity.

Further, in the above embodiment, the means for preventing the radio wave from the transmitting device 31 from leaking out of the parking space of the indoor parking lot 1 by limiting the output of the transmitted radio wave is constructed. A means for preventing radio waves from the transmission device from leaking out of the parking space of the indoor parking lot 1 may be configured by surrounding the radio wave shield on the. Further, in the above embodiment, the transmission device 31 is provided in the housing box 32 attached to the lower surface 2a of the building 2 in the multi-storey parking space 8. However, the transmission device is incorporated in the control device that controls the lifting device. In this case, the dedicated storage box necessary for installing the transmitter will be abolished, and the transmitter will be easily inspected and maintained in the control device that requires regular inspection. Become.

Moreover, in the above-mentioned embodiment, the multi-story parking space 8 has two upper and lower tiers of the upper tier 8a and the lower tier 8b, but it may be a multi-tiered parking space having three or more tiers in the vertical direction.
