Abstract

PURPOSE:To accurately manage a parking area by processing a sensor signal and a keyboard input signal, and when a parking ratio exceeds a preset value and the number of the null parking section is found out, informing it to a car intending parking by radio or display. CONSTITUTION:The parking status of each of the parking sections P1-Pn is always managed by a signal processing means based on a signal from sensors S1-Sn and an input signal from a keyboard. When the parking ratio except for the section unusable transiently exceeds 50%, the number of the section when the null section exists is supplied to a car C2 detected by entrance car detecting means 4 and 5 to the radio of the car intending parking via a voice output device 5.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention provides a system for parking lots in which the parking rate is stored at a preset value, excluding sections that are temporarily unavailable due to construction work, delivery, etc. To provide a precautionary parking position instruction method for informing a driver of a car attempting to enter a parking lot of an available parking lot number by radio or by radio and display.

[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 in a crowded parking lot or in a parking lot with multiple floors, and the method of distributing power to a manager has the drawback of requiring a lot of manpower.

This invention is intended to improve these problems.

[Means to solve the problem]

A sensor to detect whether a car is parked in each parking lot will be installed at a predetermined location in the Manen parking lot, as well as an audio output display (the main component is a speaker), a transmitter, and a transmitting antenna. , At the entrance of the parking lot, there will be a warning sign for vehicles entering.
In addition, a keyboard is provided to input the number of a section that is temporarily unavailable due to construction, etc., and the signal processing means processes the sensor signal and the number of the section that is manually input from the keyboard. After the parking rate is set in advance and the t value is determined, the driver who is about to enter is informed of the empty status of the parking lot at the time of entering by radio or by radio and display. I made it.

[Effect]

As a result of processing the numbers of unusable areas and areas entered using a keyboard with sensor signals using a signal processing means, the number of empty parking areas will be determined after the parking rate exceeds a preset value, excluding areas that are temporarily unavailable. If the lot is known, the lot number is radioed to the driver of the vehicle attempting to enter.

Or notify by radio and display.

[Example of actual collapse]

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

), indicating the car that is about to enter. 12) is the exit of the parking lot, (3) is an appropriate place in the parking lot, and 2) is the voice output device.

aS is an entrance vehicle warning means, in which a light source (4) and a light receiver 75) are arranged facing each other with the entrance tl) in between. Therefore, if the car C2 continuously emits light emitted from the light source (4), it is determined that there is an entering car 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 first transmitter and transmitting antenna are omitted in the figure. Figure 2 (8) shows the relationship between the audio output device (3) and its auxiliary equipment, and (7) Speaker, (8) is AMP, +91 is voice synthesis output device j4゜1
04 is a signal processing means connected to the plurality of sensors S1 to Sn, and 04 is a keyboard for inputting information when a section is temporarily unavailable due to construction, etc., and input to the signal processing means H using this keyboard. The number of partition t is excluded as a partition that is temporarily unavailable. 115 is a transmitter (IO
is connected to the transmitter.

αη is the transmitting antenna that transmits weak FM radio waves, αη is the car's receiving antenna, and α is the radio in the car. The parking status of each parking lot is continuously monitored by the signal processing means (11) based on the signals from each sensor and the input from the keyboard I, and is conveniently shown in the circular graph G (1). For example, the second
As shown by the steel wire in the figure (bl), if it exceeds <75%, the two-dimensional visibility within the parking lot will be quite poor. If there is, the speech synthesis output device (9) outputs a signal 0υ for converting the number of the section into speech.

l'lzke voice output device (3) and voice synthesis output device (9)
), there are nine gates installed between the voice synthesis output device (
9) and an entering vehicle detection signal (6) generated from the light receiver (5).

Note that the detection signal (6) is also given to the transmitter a5.

Therefore, if a car that intends to enter after the parking rate has reached a preset value (excluding temporarily unavailable spaces) reaches the entrance and is detected by the entering vehicle detection means O8, if the parking rate is The number of the parking lot in the parking lot is communicated via radio to the driver of the car attempting to enter.

That is, there is no audio output when there is no vehicle attempting to enter, but when there is a vehicle attempting to enter, audio output is generated and transmitted. When the driver hears an empty parking lot on the radio, all he has to do is head straight for it.
There is no need to search inside a parking lot with poor visibility when the parking rate is high. In addition, 5 For example, P9~
If Pn is temporarily unavailable, P9 to Pn are input using the keyboard α4, and the signal processing means port 1 takes the exclusion process <f as a temporarily unavailable section.

FIG. 3 shows another embodiment of the present invention, in which a predetermined parking rate is determined, and then a voice synthesis output device +]f9+
The output is displayed on a display device 4f11, and this display device q (I:n is located near the entrance (1)).

In this way, it is possible to prevent overhearing from only using the radio. Note that the display device needs to be distributed at the entrance of the parking lot, but other signal processing means etc. can be purchased at an appropriate cost. Needless to say, it can be installed.

By the way, in this invention, if the parking rate is set in advance, the driver of the entering car is informed of the vacant lot, so the parking rate is 100%.
This is because the closer you get to the parking lot, the worse the visibility inside the parking lot becomes, making it difficult to find a vacant lot.

[Effect of the Invention 1] Since the present invention is as described above, it is possible to improve the conventional lesson plan. You can also use the keyboard to manually fill out temporarily unavailable sections.

Since this is excluded, accurate parking lot management is possible.
