Description

The present invention relates to a display device that displays that the number of available vacant rooms is decreasing in a flap-type time rental parking lot.

In a large gate-type parking lot, a full or empty display device is provided for each block or floor. Also, in a time-rented parking lot provided with a flap-type exit prevention device in each vehicle compartment, a display device for displaying full or empty vehicles is installed near the parking lot entrance. In large parking lots, there are many passenger compartments, so even these two types of displays are not inconvenient for users.

However, in small and medium-sized parking lots with 10 to 20 vehicle compartments, for example, it is not possible to know the number of empty vehicle compartments by simply displaying the full vehicle vacancy. When you try to park your car, it becomes full on the way, causing the inconvenience that the remaining vehicles have to find another parking lot.

Therefore, when there is an empty room, it is convenient to have a device that displays the number of empty rooms in some form.

In Patent Document 1, in a multi-story parking lot, the number of vacant rooms on each floor is calculated based on a method using LED light shielding for detecting a parked vehicle and the detection result. Discloses a method for simultaneously displaying an empty vehicle and the number of empty vehicle rooms.

In Non-Patent Document 1, in a gate-type parking lot, a vehicle entering and a vehicle entering are detected by a sensor, the number of vehicles remaining in the field is obtained, and the number of vehicles remaining in the parking lot is subtracted from the number of vehicles accommodated in the parking lot. A device is shown that calculates the number and numerically displays how many cars are currently parked at the parking lot entrance.

Non-Patent Document 2 discloses a method of displaying, in a pie chart, how much the vacancy rate is on each floor in a multi-storey floor parking lot.

On the other hand, in time-rental parking lots equipped with small and medium-sized flap devices, the settlement machine parks vehicles parked in individual compartments based on information from sensors that detect the entry / exit of vehicles into / from individual compartments. Parking fees are charged according to the time. The checkout machine subtracts the number of currently parked vehicles from the total number of passenger compartments, and of course holds data on the number of empty passenger compartments. It is stored in the remote server of the parking system management company.

However, in such a small and medium-sized parking lot system, the number of empty cabs is stored as data, but usually only a full display is displayed, and there are hardly any indicators that actively display the number. .

In addition, it is not a parking lot, but at intersections in the city, a traffic light that blinks when the remaining time of the green light decreases and displays the time until the signal changes to inform pedestrians that the signal will change soon. It is very convenient.

In the prior art method of informing the number of remaining vehicle compartments, when there is an empty vehicle room, the empty vehicle display and the number of empty vehicles are displayed in parallel. However, this method has a drawback in that an apparatus having a high graph display cost must be used.
The present invention is intended to provide a method for easily telling a user that the remaining number of empty cabs is low at a low cost without greatly changing a general full display board.

The present invention calculates the number of vacancies with respect to the total number of rooms in a small and medium-sized parking lot, and displays the number of remaining rooms in an easy-to-understand manner. When the number of rooms becomes less than a certain limit, the blinking interval of the empty display of the conventional full display device is shortened according to the number, or a separate flashing light is installed beside the empty display.

According to the present invention, the conventional empty vacant display device is left as it is, and when the number of vacancies decreases, a circuit that blinks according to the ratio is added, and the number of vacancies remaining is reduced. Users can be actively informed and inconvenience for users can be eliminated. In addition, there is an effect that can be realized at low cost.

These are figures which show the system of the time rental parking lot which has a parked vehicle detection function for every common vehicle room. These are figures which show the system which displays the empty vehicle empty of this invention. These are figures which show another system which displays the empty vehicle empty of this invention. These are figures which show another system which displays the empty vehicle empty of this invention. These are figures which show another system which displays the empty vehicle empty of this invention. It is a figure which shows the example of the blink interval changed according to the number of the remaining empty vehicles of this invention.

FIG. 1 is a full display system of a general flap type time rental parking lot. Each vehicle compartment has a vehicle detection sensor 2 for detecting the vehicle entry. When the vehicle entry is detected, the vehicle is converted into a detection signal by the terminal device 3, and the communication line 4 notifies the settlement machine 5 of the vehicle entry into the vehicle compartment. . The CPU (calculation element) in the checkout machine 5 always calculates the number of remaining vehicle compartments by subtracting the number of compartments received from the total number of compartments.

When the remaining vehicle compartment becomes zero, the vehicle is handled as full, and a “full” display 6 is displayed on the full display board, and an “empty” display 7 is displayed if the number of remaining vehicle compartments is 1 or more, for example. In this figure, two displays are written, but the display on the same display board is actually displayed as “full” or “empty”.

Almost all the data inside the checkout machine is transmitted to the remote server 8 of the parking lot management company through the communication line 9 and stored in the database of the parking lot management system.

FIG. 2 shows a full display system of the present invention. As in FIG. 1, the checkout machine 5 having the data of the vehicles stored in the respective vehicle compartments displays the “full” display 6 as in the conventional case when the number of remaining vehicle compartments is zero. In the above case, the D-PW converter (digital-pulse converter) 10 outputs signals between different pulses depending on the number of remaining vehicle compartments. Then, the output signal is applied to the relay device 11, and the relay contact 12 is turned on and off. The relay contact 12 is connected to the power source 13 and blinks the “empty” display 7 only when the contact is on and the number of remaining vehicle compartments is 1 or more, that is, when the AND logic element 14 is AND.

FIG. 3 shows another embodiment of the present invention. The difference from FIG. 2 is that the number of remaining vehicle rooms is transmitted from the remote server 8 of the parking lot management company to the receiving device 21 of the parking lot through the communication line 20 and is converted to the number of remaining vehicle rooms by the digital pulse converter 22. It is a point converted into a corresponding pulse signal. Thereafter, in the same manner as in the case of FIG. 2, the blinking interval of the “empty” display 7 can be changed to inform the driver of the size of the remaining vehicle compartment.

FIG. 4 shows a circuit that can generate a pulse signal corresponding to the number of remaining vehicle compartments without using a settlement machine. The output contact 31 of the vehicle detection sensor in the individual compartment is connected in parallel to the resistor 32. The resistors 32 are connected in series by the number of passenger compartments. In addition, a resistor 33 is connected in series. This series resistance circuit is connected to the power supply 30. Accordingly, the voltage appearing at both ends of the resistor 33 is the vehicle detection sensor 31.
Varies depending on how many are closed. The analog pulse converter 34 generates pulse voltages having different pulse intervals depending on the voltage applied to the resistor 3. The pulse voltage is input to the relay device 35. When the output contact 36 is on and the checkout machine 5 is empty, the “empty” display 7 is lit.

In the above embodiment, the “empty” display blinks in accordance with the number of remaining vehicle compartments, but a simpler embodiment is shown in FIG. Here, the pulse signal of the digital pulse conversion device 40 receiving the number of remaining vehicle compartments from the settlement machine enters the relay device 41, and voltage is applied from the power source 43 to the blinking lamp 44 by turning on and off the output contact 42 thereof. The flashing light is made to flash according to the number of remaining vehicle compartments.
In this embodiment, the conventional full indications 6 and 7 are left as they are, and it is only necessary to newly provide a flashing light on the side thereof, which is simple.

FIG. 6 shows the relationship between the number of remaining vehicle compartments and the pulse signal. When the number of remaining vehicle compartments is large, the pulse voltage blinking interval is shortened as the time during which the pulse voltage is on is longer and shorter.

Accordingly, in any of the embodiments shown in FIGS. 2 to 5, when the number of remaining vehicle compartments is large, the “empty” display 7 blinks slowly, and when the number of remaining vehicle compartments decreases, the blinking interval is short and the lighting time is also short. Shorter.

The present invention displays the number of remaining cars in the time-rental parking lot by changing the blinking interval of the empty car display, and the equipment cost is low and it is also possible to modify the existing full indicator. . Parking users can easily determine whether there are many or few empty rooms even from a distance when running on the road. In particular, when the same parking lot is used in a group, the user has a great effect such as knowing that a plurality of vehicles can be parked in the same parking lot.
