JP7075554B2 - Parking lot sign with vacant room number display - Google Patents

Description

The present invention relates to a parking lot signboard that can display the number of vacant parking lots that can be used in an hourly parking lot that can calculate the parking time for each parking lot.

In a large gate-type parking lot, a display device for full or empty cars is provided for each block or each floor. Further, even in an hourly parking lot equipped with a vehicle detection device in each vehicle compartment, a parking lot signboard indicating full or empty vehicles is installed near the parking lot entrance. In a large parking lot, there are many passenger compartments, so there is no inconvenience for users with just these two types of displays.

However, in a small-to-medium-sized parking lot where the number of parking lots is, for example, 10 to 20, the number of empty parking lots cannot be determined only by displaying the empty cars. The inconvenience of having to find another parking lot for the rest of the vehicles when the car is full on the way, such as when trying to park, or the congestion of the parking lot in the area you want to park is unknown. Inconvenience occurs.

Therefore, if there are vacant rooms, it is convenient to have a parking lot sign that displays the number of vacant rooms. Some display devices for vacant rooms are disclosed in the following prior art documents.

Japanese Patent Application Laid-Open No. 07-22009

Utility model No. 3018828 Real Kaihei 03-82499 Utility model registration No. 3195326 (U3195326)

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

In Non-Patent Document 1, in a gate-type parking lot, a sensor detects vehicles entering and exiting, the number of vehicles remaining in the parking lot is obtained, and the number is subtracted from the number of vehicles accommodated in the parking lot to enter the vacant room. A device that calculates the number and numerically displays how many cars can be parked at the entrance of the parking lot is shown.

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

On the other hand, in an hourly parking lot equipped with a small and medium-sized flap device, the checkout machine parks the vehicle parked in each compartment based on the information of the sensor that detects the entry and exit of the vehicle into each compartment. We charge a parking fee according to the time. The checkout machine can also calculate the number of empty cabs by subtracting the number of currently parked vehicles from the total number of cabs.

A display device capable of displaying the number of vacant rooms even in such a small-to-medium-sized parking lot can be found in Non-Patent Document 3. That is, if there is an vacant parking lot externally attached to the lower part of the conventional parking lot signboard that can display the full vacancy, the number of vacant parking lots can be displayed.

However, it is unattractive to display the number of remaining vehicle rooms at the bottom of the full sky display on the conventional parking lot signboard with an external display device. Also, rather than displaying only the number of remaining car rooms, when a person looks at the signboard, it is possible to easily grasp the status of vacant cars in the parking lot. I also knew that it would be easier to understand if I added the letters.

Further, when trying to display the number of remaining vehicle rooms on the LED display board, for example, when there are 10 or more remaining vehicle rooms, the number of display digits becomes double digits and the display panel becomes large and expensive. It has also become clear that there is. Therefore, I thought that an integrated parking lot signboard with an improved display method and a display of the number of remaining cars would be necessary.

In the present invention, as a signboard for a small-to-medium-sized hourly parking lot, the full space display part is not only a "full" sign indicating a full car or an "empty" sign indicating an empty car, but also 10 when there is an empty car room. When the number of empty parking lots is less than 1, "empty" is displayed and "5" is displayed alternately when the number of empty parking lots is 5, for example, at a time interval and length that are easy to understand intuitively. In addition, when the number of remaining parking lots is 10 or more, the number of remaining parking lots is not displayed in order to avoid the limitation of the display size of the LED display panel and the increase in size and cost. A smart integrated parking lot sign with an empty room display has been realized by displaying an arrow pointing toward the inside of the parking lot that can be guided to the parking lot with an "empty" display and an appropriate time interval and length.

According to the present invention, when there is an empty room that is not parked in the parking lot, a smart integrated empty room that can display the status of the empty vehicle according to the amount of the remaining vehicle room, unlike the conventional full empty display. Since a parking lot sign with a number display can be installed, parking lot users can know how crowded the parking lot is in the area they want to park, and it is possible to select and park a parking lot that is easy to park, and the parking lot owner. However, there is an effect that it can be expected to improve the occupancy rate of the parking lot.

It is a figure which shows the parking lot signboard which can display the empty and the number of the remaining car rooms when there is a remaining car room of this invention. It is a figure explaining how to display in the parking lot signboard of this invention when the car is full and the number of remaining car rooms is 9 or less, and when the number of remaining car rooms is 10 or more. It is a figure showing the signal (data) sent from the checkout machine to the display controller of a signboard according to the parking situation, and the content to be displayed on the parking lot signboard according to the signal in the parking lot signboard of the present invention. Is a parking lot signboard of the present invention, which is a diagram showing the signal and the corresponding state display content when the number of remaining vehicle rooms is 10 or more. Is the parking lot signboard of the present invention, which indicates the signal and the full character when the car is full. Is a diagram showing a specific signal line and terminal board for sending a signal according to a parking situation from a payment machine to the parking lot signboard of the present invention, and a controller for an LED display board of the parking lot signboard receiving the signal.

FIG. 1 shows a display example of a full vacancy display LED board when there is an empty vacant room in the parking lot of the present invention. It shows the conventional indication that there is. Conventionally, only the sky is displayed regardless of the size of the number of remaining car rooms, but in the present invention, the empty characters and the number of remaining car rooms of 9 cars are displayed alternately.

If the parking lot user can know whether the parking lot is crowded or the parking lot has plenty of parking space, the psychological effect of parking in the parking lot with plenty of space can be expected. , The occupancy rate of parking lots that show the number of remaining cars will improve.

However, as a result of various studies on improving the visibility of the inventors, it was found that the number indicating the sky and the number of remaining passenger compartments alone does not necessarily indicate the number of remaining passenger compartments, which can be seen from FIG. As described above, in the present invention, a device is devised to insert the character "table" next to the number. This full sky and number display will use the LED display board, but due to the size of the display frame and cost restrictions, if there are 10 or more remaining car rooms, write numbers and the letters "unit". Turned out to be unreasonable.

Therefore, in the present invention, as shown in FIG. 2, the display of the LED display panel is divided into three cases according to the parking state of the parking lot. That is, when all the passenger compartments are parked, the characters "full" will continue to be displayed in red, etc. as before, but only when the number of remaining passenger compartments is 9 or less, the characters "empty" and the remaining passenger compartments will be displayed. We decided to set the number of passenger compartments to, for example, 7 and display both with a display time and display interval with good visibility. As a result of the experiment, it was found that it is best to display "empty" for 1.7 seconds and the number of units for 0.7 seconds. However, it goes without saying that such a time interval and the like can be arbitrarily changed by setting in the present invention.

Next, if there are 10 or more remaining passenger compartments, if the letters "empty" and the two-digit number of 10 or more are displayed, the letters in the display panel must be made smaller, resulting in poor visibility. Therefore, in the present invention, as described in the case where the number of remaining vehicle rooms is 10 or more in FIG. 2, the number of vehicles displayed alternately with "empty" is not displayed, but the vehicle heads toward the parking lot. I decided to display a moving arrow.

Next, I would like to explain how to display the full sky according to the parking condition as shown in FIG. FIG. 3 shows a signal (data) transmitted from the checkout machine to the signal receiving terminal of the LED display board of the parking lot signboard of the present invention capable of displaying the remaining number. The data is composed of 4-bit data, and a voltage of 5V or no voltage is sent between the four signal lines and the common electric wire. Since 5V is recognized as 1 in the signal and 0 in the no-voltage, 16 different data can be sent in the end. In the following description, the voltage to be applied is 5V, but the voltage is not limited to that, and may be the optimum voltage for the controller.

As can be seen in FIG. 3, in the present invention, a 4-bit signal is assigned as shown. That is, when the number of remaining passenger compartments is only one, "0000", that is, no voltage is sent to the four signal lines. When the number of remaining passenger compartments is two, a predetermined voltage is applied only to the fourth signal line as "0001". Hereinafter, when the number of remaining passenger compartments is 9, a signal of "1000" is sent from "0010". Then, the LED display controller alternately displays the displays such as "empty" and "7 units" prepared in advance for these signals at a predetermined display time and time interval.

Then, when the number of remaining passenger compartments exceeds 10, the signals from "1001" to "1110" are sequentially sent to the controller of the LED display panel at regular time intervals regardless of the number of remaining passenger compartments.
The display of the LED display board for this signal is as shown in FIG. That is, for the signal of "1001", the arrow pointing to the right in the center of the display panel, for the signal of the next "1010", the arrow moves slightly to the right, and for the next "1011". Is like the arrow moving from the left end, for "1100" to "1110", the arrow goes to the right, and finally, like "1001", it returns to the center arrow. ing. Therefore, these are displayed cyclically at regular time intervals, and the person who sees this signboard is displayed with a moving arrow that guides the inside of the parking lot.

When the vehicle is full, the signal "1111" is received as shown in FIG. 5, so that the controller of the LED display panel continuously displays the prepared characters "full".

FIG. 6 shows a wiring diagram of a circuit that sends the signal (data) from the checkout machine to the controller of the full sky display board of the parking lot signboard. The checkout machine 21 has data on the parking lot room and a file 33 that records and manages parking for each parking lot, and can calculate the number of remaining parking lots that change from moment to moment. ing. The number of remaining passenger compartments is converted into 4-bit data, and the bit data corresponding to the four signal lines displayed from the terminal 34 to 28 to 31 of the checkout machine is stored in the controller 23 of the LED display board of the parking lot signboard. Sent. The signal line indicated by 32 is a common line, and a predetermined voltage is applied between the four signal lines according to the parking state. As described above, the controller of the LED display panel displays the prepared number of units according to the transmitted signal.

In FIG. 6, the signal lines 25 and 26 enclosed by circles 24 are signal lines used to display the characters "full" and "empty" on the LED display board of the parking lot signboard, and there is no space between 25 and 26. When the voltage is applied, "empty" is displayed, and when the default voltage is applied, "full" is displayed. Therefore, in the present invention, when there is a remaining passenger compartment, the time for making no voltage between 25 and 26 is set to 1.7 seconds, and for the next 0.7 seconds, 27 rounded 4-bit signal lines are used. Based on the data from, the number of remaining passenger compartments is displayed on the LED display panel. However, when the number of remaining vehicle rooms is 10 or more, as shown in FIG. 4, the signals from "1001" to "1110" are sequentially sent during the time zone when the number of remaining vehicle rooms is displayed. Therefore, after the display of "empty", a moving arrow that guides you into the parking lot is displayed.

When the parking lot is full, a predetermined voltage is applied to the signal line enclosed by the circle 24, and the characters "full" are continuously displayed.

In the first embodiment, when the number of remaining passenger compartments exceeds 10, signals from the checkout machine to "1001" to "1110" are sequentially sent to the full sky display panel controller, but the checkout machine, for example, " When the signal of "1001" is sent, the controller of the full sky display board may automatically generate a signal from "1001" to "1110", thereby displaying a moving arrow on the full sky display board. ..

The colors of the full, sky, and the number and moving arrows of the full sky display board may be displayed in different colors and seconds as appropriate for good visibility.

In the first embodiment, it is described that when the 4-bit signal is 1, the checkout machine sends a voltage of 5 V to the controller of the full-empty display panel, and when it is 0, the voltage is set to no voltage. When the signal is 1, the contact between the communication line and the common line 31 may be turned on, and when the signal is 0, it may be turned off, and the voltage required for the LED display may be applied by the controller of the LED display panel. ..

In the first embodiment, four wired signal lines are used as a means for communicating a 4-bit signal from the checkout machine to the full / empty display panel, but if similar communication is secured, the number of signal lines does not matter. The signal line may be wired or wireless.

In the present invention, the number of remaining car rooms that can be parked in the hourly parking lot is displayed on the conventional LED full sky display board as "empty" and the number of remaining car rooms is 7 cars. In addition to displaying characters with characters alternately at the set display time and time interval, if there are 10 or more remaining cars, the characters "empty" and guidance to the parking lot will be displayed. Since the moving arrows are displayed alternately, it is possible to provide new information such as how busy the parking lot is to the parking lot users, compared to the conventional full sky display. This has the effect of improving the occupancy rate for parking lot owners and improving convenience for users, such as being able to select a parking lot that is easy to park without being impatient. Such parking lots are also heavily utilized industrially.
