Abstract

PURPOSE:To prevent >= two vehicles from being allocated on the same parking lot by notifying the number of a vacant lot to a vehicle driver, and preventing the parking lot number from being handled as the vacant lot even if it is in the vacant condition until the passage of the prescribed time. CONSTITUTION:When a parking rate exceeds a value set beforehand, and the vacant lot exists, a signal 11 to convert the lot number is outputted from a voice synthesizing device 9. Consequently, when the vehicle arrives at an entrance, and it is detected by an entering vehicle detecting means, the vacant parking lot number at such a time point is outputted from a radio. A timer 14 is set at a prescribed time, and a signal processing means 10 is controlled so as not to handle the lot as the vacant lot until the passage of the prescribed time. Thus, two vehicles can be prevented from being allocated to the same parking lot.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention provides a parking lot where drivers of cars attempting to enter the parking lot after the parking rate exceeds a preset value. This invention relates to a method for indicating a parking location in which the parking lot number is notified by radio or by displaying the radio.

[Conventional technology]

Conventionally, in parking lots such as supermarkets, vehicles entering the parking lot either search for an empty parking lot on their own or are guided to an empty parking lot according to instructions from the parking lot manager.

[Problem to be solved by the invention]

It is not easy to find an empty parking lot during busy times or in a parking lot with multiple floors, and the method of allocating managers has the disadvantage that it requires a lot of manpower.

This invention is intended to improve such problems.

[Means for solving H problem]

Sensors are installed in each parking lot to detect whether or not a car is parked, and audio output devices are installed at designated locations in the parking lot! (The main component is a speaker), a transmitter and a transmitting antenna that transmit the audio output using weak FM radio waves, and an entrance vehicle detection means is installed at the entrance of the parking lot, and the signal from the sensor is processed by a signal processing means. At the same time, after the parking rate exceeds a preset ratio value, the driver of the vehicle attempting to enter is informed of the empty status of the parking lot at the time of entry via radio or by radio and display. I made it.

[Effect]

As a result of processing the sensor signal with a signal processing means, if an empty parking lot is found after the parking rate exceeds a preset value, the number of that lot will be sent to the driver of the car about to enter. In addition to being notified by radio or by radio and display, parking lot numbers where parking is available are output audibly.Even if the lot is vacant, it will not be treated as an empty lot until a predetermined time has elapsed. Avoid having two or more cars in a block.

〔Example〕

Figure 1 shows a schematic diagram of a parking lot, where P1 to Pn are parking bays, and s1 to Sn are sensors (for example, metal detectors) installed in each parking bay to check whether a car is parked. It detects whether or not it is present and provides it to the signal processing means.

C1 and C2 are cars, (1 indicates a car already parked in the parking lot, and 02 indicates a car at the entrance (1) of the parking lot that is about to enter.
2) is an exit of the parking lot, and (3) is an audio output device provided at a predetermined position in the parking lot. aS is an entering vehicle detection means, and a light source (4) and a light receiver (5) are arranged facing each other with the entrance (1) in between. Therefore, if the car C2 blocks the light generated from the light source (4), it is determined that the entering car is at the entrance. Note that a detection signal (6) from the light receiver (5) is given to a gate circuit and a transmitter, which will be described later. Note that the transmitter and transmitting antenna are omitted in the first factor.

Figure 2 (al shows the relationship between the audio output device (3) and its ancillary devices, (7) is the speaker, (8) is A)
P.

(9) is a voice synthesis output device, and aC is the plurality of sensors S mentioned above.
Signal processing means connected to 1 to Sn, alJ is a timer.

(19 is the audio output transmitter, σe is the transmitting antenna, F
Transmits weak radio waves of M. αη is the car's receiving antenna.

(I♂ is the radio inside the car.The parking status of each parking lot is constantly monitored by the signal processing means αG based on the signals from each sensor, and the parking rate shown conveniently in the circular graph G is determined in advance. Set value 1 For example, as shown by the diagonal line in M2 diagram (1)), if it exceeds 75%, the two-dimensional visibility within the parking lot will become poor, so after exceeding the preset parking rate. If there is a vacant section, the speech synthesis output device (9) outputs a signal αυ for converting the number of the section into speech. C1Z is an audio output device (3
) and the voice synthesis output device a (9), into which an entering vehicle detection signal (6) generated from the voice synthesis output device (9) and the light receiver (5) is input. Note that the detection signal (6) is also given to the transmitter (5).

Therefore, if a car trying to enter reaches the entrance after the parking rate exceeds a preset value and is detected by the entering car detection means 0 days, the number of the vacant parking lot at that time will be transmitted from the radio. Output.

That is, when there is no car trying to enter, K's audio output device and transmitter do not operate, and if there is a car trying to enter, audio output is generated and sent to Radio U via the transmitter and transmitting antenna. .

When a driver hears about an empty parking lot on the radio, he or she can drive straight to that lot without having to search around the lot.

By the way, the car does not arrive at the parking lot immediately after passing through the entrance, but it takes some time. Therefore, until the vehicle reaches the parking lot, the parking lot remains vacant even though the parking location has been instructed to the entering vehicle. If you specify the same parking lot for the next car, it is not desirable that the two cars end up in the same lot. Therefore, a predetermined time is set using a timer α, and the signal processing means is controlled so that the block is not handled as an empty block until the predetermined time has elapsed. If the block is still vacant after a predetermined period of time, the block will be outputted again as an empty block.

FIG. 3 shows another embodiment of the present invention, in which the output of the speech synthesis output device (9) is displayed on a display device a3, and this display device a3 is located near the entrance (1). It has been placed.

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

Note that one display device must be placed at the entrance of the parking lot, but it goes without saying that other signal processing means and the like may be installed at other appropriate locations.

By the way, in this invention, if the parking rate exceeds a preset parking rate, the driver of the entering vehicle is informed of the vacant lot, which is the reason why the parking rate is 100%.
The closer you get to the parking lot, the worse the visibility inside the parking lot becomes, making it difficult to find an empty space.

〔Effect of the invention〕

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