Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking lot automatic management system.

[0002]

2. Description of the Related Art Generally, in a large-scale parking lot, it is necessary to prevent the vehicle from being parked without permission and to settle the usage fee.

Conventionally, the following two methods have been mainly used to manage this type of parking lot. Management by people Management by automatic ticket issuing machine

Here, the management by a person means that the manager monitors the entry and exit of an automobile and records the number and time. In addition, management with an automatic ticket issuing machine means that an automatic ticket issuing machine and a gate are placed at the entrance of the parking lot, and the gate is opened on condition that the driver of the car has received the ticket and the ticket is submitted when leaving. It is the one.

[0005]

As described above, in the past, two types of management were mainly performed, but the following drawbacks were pointed out. Personnel management is costly due to personnel costs. The recording may be lost and the reliability is not always high. If the caretaker happens to be absent, he cannot enter or leave the parking lot. Some people dislike it because they have to contact the caretaker each time they enter or leave the parking lot. Management by an automatic ticket issuing machine is cumbersome because it requires opening the window of the car and extending the hand to receive the ticket. In Japan, automatic ticket issuing machines are often located on the right side of the driver, but with an outside car with a left-hand drive, if you are driving alone, you have to get off the car and receive the ticket, which is very complicated. Is.

The present invention has been proposed in view of the above points, and an object thereof is to provide an automatic parking lot management device that can automatically manage and that does not burden the driver as much as possible. To do.

[0007]

In order to achieve the above object, the present invention is attached to a part of an automobile and weakens the ID data assigned to itself when a predetermined induction electromagnetic field is detected from the outside. A non-contact ID tag that transmits by radio waves, an ID reader that is arranged near a doorway of a parking lot, generates an induction electromagnetic field in the surroundings, and receives weak radio waves including ID data, and the ID reader. A computer system that identifies vehicles entering and exiting the parking lot from the ID data received via the, and performs processing such as entry / exit control and settlement of usage fees is provided.

[0008]

In the automatic parking lot management system of the present invention, the ID reader arranged near the entrance of the parking lot generates an induction electromagnetic field in the surroundings. On the other hand, the non-contact ID tag attached to a part of the automobile detects the induction electromagnetic field generated by the ID reader when the automobile reaches the vicinity of the entrance of the parking lot, and weakens the ID data assigned to itself. Send over radio waves. The ID reading device receives the weak radio wave containing the ID data and passes it to the computer system. Then, the computer system identifies a vehicle entering and exiting the parking lot from the ID data received via the ID reading device, and performs processing such as entry / exit control and settlement of the usage fee.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an automatic parking lot management apparatus of the present invention.

In FIG. 1, a small non-contact ID tag 2 is attached to an automobile 1. As a method of attachment, it is desirable to fix it to the bottom surface of the automobile 1 in advance or place it on the inner end of the front window, but it is not limited to this.

The non-contact ID tag 2 has a function of transmitting ID data assigned to itself on a weak radio wave when a predetermined induction electromagnetic field is detected from the outside, and is shown in FIG. As described above, the electromagnetic induction sensor 21 that detects the induction electromagnetic field from the outside, the ID storage unit 23 that stores the ID data, and the ID data from the ID storage unit 23 when the electromagnetic induction sensor 21 detects the induction electromagnetic field. It includes a weak radio wave transmission unit 22 that reads out and transmits on a weak radio wave.

In FIG. 1, an ID reader 4 is provided near the entrance 3 of the parking lot. For example, it is desirable to embed it on the road surface or to provide it on a pole or the like standing upright from the road surface, but it is not limited to this.

The ID reading device 4 has a function of generating an induction electromagnetic field in the surroundings and receiving a weak radio wave containing ID data. As shown in FIG. A generated induction electromagnetic field generation unit 41, a weak radio wave reception unit 42 that receives a weak radio wave including ID data from the non-contact ID tag 2, and ID data extracted from the received signal are delivered to the computer system 7 described later. The induction electromagnetic field generation unit 41 includes an interface unit 43 for giving control from the computer system 7.

In FIG. 1, a gate 5 for permitting / blocking the passage of an automobile 1 is provided at a parking lot entrance / exit 3 and is opened / closed by a gate opening / closing device 6.

On the other hand, the ID reading device 4 and the gate opening / closing device 6 are connected to a computer system 7. The computer system 7 identifies the vehicle entering and leaving the parking lot based on the ID data received from the non-contact ID tag 2 on the vehicle 1 via the ID reading device 4, and performs processing such as entry / exit control and settlement of usage fees. It has a function to do.

Although the exit and entrance of the parking lot are shown as the parking lot entrance and exit 3 in FIG. 1, when the entrance and the exit are provided separately, an ID reader 4 and a gate 5 and a gate 5 and a gate 5, respectively. A gate opening / closing device 6 is provided.

Next, the operation of the above embodiment will be described.

Under the control of the computer system 7, the ID reader 4 constantly generates an induction electromagnetic field within a predetermined range by the induction electromagnetic field generator 41 during a time zone when the parking lot is available.

At this time, when the automobile 1 having the non-contact ID tag 2 approaches the parking lot entrance / exit 3, the electromagnetic induction sensor 21 of the non-contact ID tag 2 detects the induction electromagnetic field emitted from the ID reader 4. , The weak radio wave transmission unit 22 is the ID storage unit 2
The ID data stored in 3 is transmitted on a weak radio wave.

The weak radio wave receiving section 42 of the ID reader 4 is
When the weak radio wave from the non-contact ID tag 2 is received, it is demodulated, the ID data is extracted, and the computer system 7 is notified of the ID data via the interface unit 43.

In the computer system 7, it is judged whether the received ID data is valid or not, and if it is valid, the gate opening / closing device 6 is operated to open the gate 5 to permit the passage of the automobile 1. At the same time, the entry / exit information is recorded as management data in association with the ID data.
If it is necessary to manage the usage time for settlement of usage fees, the time of entry / exit is also recorded.

The computer system 7 also performs various other processes, such as calculation of the usage fee when exiting and control of its automatic collection.

[0024]

As described above, the automatic parking lot management system of the present invention has the following effects. Since the parking lot can be managed automatically, the cost can be reduced compared to the management by a person. Management is highly reliable because there is no human intervention. There is no possibility that you will not be able to enter or leave the parking lot due to the absence of a manager. In the case of monthly contract vehicles, once the contactless ID tag is issued, the parking lot can be used without any contact with people, so there is no need to deal with people. With the non-contact ID tag, there is no need to put a hand out of the vehicle, which eliminates the hassle. In particular, in the case of the left-hand drive outer car, there is a big difference compared to the conventional case where the user had to go out.
