Abstract

PURPOSE:To easily search an idle parking section by informing a driver, who will park his vehicle, of the idle parking section by radio at the time when the parking rate exceeds a preliminarily set value. CONSTITUTION:Sensors S1 to Sn to detect whether vehicles are parked or not are provided in parking sections P1 to Pn, and a voice output device 3 and an FM transmitter 11 which transmits the voice output are provided in prescribed positions of a parking lot. After the parking rate exceeds the preliminarily set value, numbers of idle parking sections are reported to drivers, who will park their vehicles in the parking lot, and parking sections whose numbers are outputted with a voice as idle parking section numbers are not handled as idle parking section till elapse of a prescribed time after the voice output though these sections are idle, and thereby, two or more vehicles are prevented from being parked in one section. Consequently, it is sufficient if the driver drives his vehicle to the parking section whose number is heard by radio.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention is applicable to a parking lot where the parking lot entrance is closed after the parking rate exceeds a preset value, excluding parking lots that are temporarily unavailable due to construction, etc. This invention relates to a method for indicating a parking position in which a driver intending to enter a parking lot is informed of vacant parking lot numbers, excluding temporarily unusable spaces, by a radio or by a radio and a display.

[Conventional technology]

Conventionally, in parking lots of supermarkets and the like, visitors either search for an empty parking lot on their own or are guided to an empty parking lot according to instructions from a parking lot manager.

[Problem to be solved by the invention]

It is difficult to find an empty parking lot during busy times or in multi-story parking lots (and the method of assigning a manager has the disadvantage of requiring a lot of manpower. This invention solves these problems. It is something.

[Means to solve the problem]

A sensor is installed in each parking lot to detect whether or not a car is parked, and a sound output device (the main component is a speaker) is installed at a predetermined position in the parking lot, a transmitter that transmits audio output, and a transmitter. A transmitting antenna that transmits weak FM radio waves is installed, and a keyboard is installed to input the area that is temporarily unavailable due to construction, etc., and the signal from the sensor and the area that is temporarily unavailable that is input using the keyboard are connected. The signal processing means installed adjacent to the audio output device or at an appropriate location away from the audio output device constantly monitors the parking status of each parking lot, and also monitors the parking rate except for temporarily unavailable spaces. - After exceeding a set value, the driver is informed of the number of an empty parking lot by radio.

[Effect]

As a result of signal processing by the signal processing means, after the parking rate exceeds a preset value excluding temporarily unusable spaces, when it is found that empty parking spaces excluding temporarily unusable spaces are found. The system not only informs the driver of a car attempting to enter the parking lot of the number of the parking lot by radio, but also displays the available parking lot number that is output aloud until a predetermined period of time elapses after the voice output, even if it is vacant. Even if there is, it will not be treated as an empty plot, and two
Prevent more than one car from being duplicated.

〔Example〕

Figure 1 schematically shows a parking lot, where PI to P are parking bays and sensors (for example, metal detectors) are placed in each parking bay to detect whether or not a car is parked. detects whether the signal is present and provides it to the signal processing means. C,,
C, represents a car, CI represents a car already parked in the parking lot, and C2 represents a car that has arrived at the entrance (1) of the parking lot. (2) is the exit of the parking lot, and (3) is an audio output device installed at an appropriate position within the parking lot. Note that the transmitter and transmitting antenna are omitted in FIG.

Figure 2 (a) shows the relationship between the audio output device (3) and its ancillary devices, where (4) is the speaker and (5) is the AMP.
(6) is a voice synthesis output device, (7) is a signal processing means connected to two or more sensors S1 to S, and (9) is a timer (IQ) that is used temporarily for work, delivery, etc. (11) is a transmitter that transmits the audio output from the audio output device, (+2)
is a transmitting antenna connected to the transmitter (11), which transmits weak FM radio waves. (13) is the car's receiving antenna, (+
4) is the radio in the car. The parking status of each parking lot is constantly monitored by the signal processing means 7) based on the signals from each sensor and the parking lot that is temporarily unavailable inputted using the keyboard (10). The parking rate, which is conveniently shown in the circular graph G excluding sections, is set to a value 1, for example, <75 as shown by diagonal lines in FIG. 2(b).
%, the two-dimensional visibility inside the parking lot will be quite poor (it is thought that the two-dimensional visibility in the parking lot will be quite poor), so the driver of the car trying to enter is instructed by radio to the vacant lot as follows.In other words, excluding the lot that is temporarily unavailable. If there is an empty section, the voice synthesis output device outputs a signal to convert the number of the section into voice, and the A needle (5)
is applied to the speaker (4) via. The output of the speaker (4) is then transmitted via a transmitter (11) and an antenna (12) and broadcast from the radio for the driver to check. Therefore, the driver only has to move the truck to the parking lot whose number is heard on the radio.

2. For example, if sections P and ~Pn are temporarily unavailable due to construction, the keyboard (10) can be used to select sections P and Pn.
~P, and take exclusion action.

By the way, the car does not reach the parking area immediately after passing through the entrance, but it takes a certain amount of time. Therefore, until the car reaches the parking lot, it remains vacant even though the parking location has been instructed. Therefore, if you specify the same parking lot in the next width, two cars will go to the same lot, which is not desirable. Therefore, a predetermined time is set using a timer (9), and the signal processing means is controlled so that the section where the audio is output is not treated as an empty section until the predetermined time has elapsed. If the block is still vacant after a predetermined period of time, it is output as a vacant block.

FIG. 3 shows another embodiment of the present invention, in which a display device displays the output of the speech synthesis output device (6) after the parking rate exceeds a preset parking rate, except for sections that are temporarily unavailable due to construction, etc. (8), and this display device (
8) is placed near the entrance (+).

In this way, it is possible to prevent listening only to the radio.

Although the second display device (8) needs to be placed at the entrance of the parking lot, it goes without saying that other signal processing means, transmitters, etc. may be placed at other appropriate locations.

By the way, in this invention, when the parking rate exceeds the preset parking rate, the driver of the car trying to enter the vacant lot is notified by radio.When the parking rate is low, the visibility inside the parking lot is often a problem. However, this is because when the parking rate increases, it becomes difficult to find an empty space on your own.

〔Effect of the invention〕

Since the present invention is configured as described above, it is possible to improve the conventional problems.

Furthermore, since sections that are temporarily unusable due to construction or the like are excluded from processing, accurate parking lot management is possible.
