Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a parking lot management device that automatically manages the entry and exit of vehicles and the calculation and collection of parking fees under the supervision of a microcomputer or the like. The present invention relates to a parking lot management device equipped with means for preventing unauthorized use of parking tickets that sometimes occurs.

[Conventional technology]

2. Description of the Related Art Hitherto, parking lot management devices of various structures have been proposed that automatically manage the entry and exit of vehicles, calculation and collection of parking fees, etc. using microcomputers and the like. Although such an automatic management device makes it possible to make parking lots unmanned, there are the following problems associated with unmanned parking. In other words, in such parking lots with unmanned automatic reception desks, parking tickets are issued with information such as the time of entry punched or magnetically written on them. Instead of entering the parking lot, the driver goes back and illegally takes away the parking ticket, allows other cars in the parking lot that were already parked with that ticket to exit the parking lot, and then leaves the parking lot for a parking fee for a shorter parking time than the actual parking time. There were cases where parking tickets were fraudulently used.

For this purpose, a vehicle detector installed at the entrance of a parking lot is used to detect whether a vehicle has entered the parking lot after collecting a parking ticket.
Or, by checking whether the vehicle has turned back without entering the parking lot, recording the parking ticket number and time of parking (or just the number) when the vehicle enters the parking lot, and comparing and checking these records when exiting the parking lot. A management method has been proposed to prevent unauthorized use of the parking ticket described above. (For example, see Japanese Patent Application Laid-Open No. 56-96390.) [Problem to be Solved by the Invention] However, according to the above-mentioned management method, the number of all officially used parking tickets (or the number and parking time partner) ), it is necessary to create a registration area for all parking spaces in the register on the management device side. There was a problem that it became larger and more expensive.

Therefore, a technical problem of the present invention is to completely prevent unauthorized use of parking tickets using a relatively small-sized management device with a small storage capacity.

[Means to solve the problem]

The measures taken in the present invention to solve the above technical problems are as follows.

A parking ticket issuing machine that automatically issues a parking ticket with the entry time registered in response to a detection signal from a vehicle detector installed outside the entrance of the parking lot, and a parking ticket issuing machine that automatically issues a parking ticket with the entry time registered, and a parking ticket that is released when the issued parking ticket is removed from the issuing entrance. An entrance gate that allows vehicles to enter the parking lot, and an automatic toll that is installed at the exit of the parking lot and automatically calculates the parking fee based on the recorded parking time when the parking ticket is inserted. In a parking lot management device equipped with a payment machine and an exit gate that opens when the calculated parking fee is paid and allows vehicles to leave the parking lot, (1) issue a parking ticket to the above-mentioned parking ticket issuing machine; To provide a recording means for recording a secret number together with the parking time on a parking ticket.

(2) When issuing a parking ticket, the above-mentioned secret number is registered in the above-mentioned automatic fare adjustment machine together with the time of entry, and when the vehicle detector installed inside the entrance entrance detects the passage of an entering vehicle, A shipping condition registration means shall be provided to delete the record of the secret number.

(3) Similarly, the automatic fare adjustment machine compares the recorded content of the parking ticket inserted into the automatic fare adjustment machine with the registered content of the exit condition registration means, and adds a secret number to the registered content of the exit condition registration means. To provide a check means for stopping payment of a parking fee by an automatic fare adjustment machine when parking fees remain.

[Effect]

The above means works as follows.

Element (1) above means that when the vehicle detector installed outside the parking entrance detects an entering vehicle, the parking ticket issuing machine issues a parking ticket with the entry time and secret number recorded. enable.

The element (2) above is that when the parking ticket issuing machine issues the above parking ticket, it registers the above secret number and entry time together in the register of the automatic fare adjustment machine installed at the exit exit, and If you receive a parking ticket and park your vehicle in the parking lot, the secret number will be deleted from the register above, but if you receive a parking ticket and return the vehicle without parking it,
The secret number is not deleted, but is left in the register and can be used as a material for determining whether or not the vehicle has been officially parked.

Element (3) above means that if the secret number remains in the register, the payment of the parking fee will be stopped as it is assumed that the parking ticket is being used fraudulently without allowing the vehicle to enter the parking lot, and the unauthorized exit of the vehicle will be prevented. Therefore, the register only needs to store the secret number of the parking ticket that was received illegally without entering the vehicle, compared to the method of storing the parking number of every vehicle entered. To make it possible to use a small, low-cost management device with a small storage capacity.

As described above, the above-mentioned technical problem can be solved by the above-mentioned means, and the problems of the conventional technology can be solved.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1A is a block diagram showing a schematic configuration of a parking lot management device according to the present invention, in which 10 is a parking ticket issuing machine provided at the entrance 20A of the parking lot 20, and 12 is a parking ticket issuing machine provided at the entrance 20A of the parking lot 20. This is the first entrance vehicle detector such as a loop coil installed on the entrance side of the
When a vehicle traveling forward steps on this detector 12, a detection signal f1 is input from the detector 12 to the parking ticket issuing machine 10, and this parking ticket issuing machine 10 calculates the current time ( Parking ticket PT with punched or magnetically written parking ticket PT and appropriate secret number (hereinafter referred to as secret number) is issued at issue port 10a.
Issued on. Then, this issued parking ticket PT
When the user pulls out the ticket from the issuing port 10a, the entry time and secret number are registered in the register of the arithmetic processing unit 14' built in the automatic fare adjustment machine 14 provided at the exit port 20B. A registration signal f2 is output.

In addition, if the user does not take out the parking ticket PT issued to the issuing gate 10a and returns home, the waste ticket processing machine built in the parking ticket issuing machine 10 will remove the parking ticket PT after a certain period of time. The system is designed to process discarded tickets, but the discarded ticket processing machine and the parking ticket
The means for recording the parking time and secret number for the PT, and the means for detecting the sampling of the parking ticket PT are as follows:
Since both can be handled by known technical means, they are omitted in the drawings.

Next, 16 is an actuating device for an entrance gate 16G provided on the path of the storage entrance 20A, and this actuating device 16 outputs the parking ticket from the parking ticket issuing machine 10 when the parking ticket PT is pulled out from the issuing port 10a. The entrance gate 16G is actuated by the gate opening signal f3 to open the entrance gate 16G, allowing entry of a vehicle. Further, reference numeral 18 denotes a second entrance vehicle detector consisting of a loop coil or the like installed in the entrance passageway inside the entrance gate 16G. , outputs the entry confirmation signal f5 to the memory in the automatic fare adjustment machine 14 described above, deletes the registration of the secret number described above, and further outputs the gate close signal f4 to the gate operating device 16.
is output and the entrance gate 16G is closed. In this way, the vehicle that has passed through the entrance 20A enters the designated parking area of the parking lot 20 as indicated by the arrow PAf, and the entry is completed.

22 is the first one provided at the exit 20B of the parking lot 20.
When the exit vehicle detector 22, which is composed of a loop coil or the like, detects an exit vehicle, an acceptance start signal f6 is output to the automatic fare adjustment machine 14 also installed at the exit exit 20B. When the automatic fare adjustment machine 14 sends and receives this acceptance start signal f6, it opens the parking ticket acceptance port 14a to enable the insertion of the parking ticket PT, and also performs arithmetic processing such as checking for unauthorized use of the parking ticket PT and calculating the parking fee. becomes readable and writable. When the parking ticket PT is inserted into the above-mentioned receiving port 14a in this state, the arithmetic processing unit 14' calculates the parking time and current time recorded in the parking ticket PT.
Calculate the parking fee by calculating the time difference between the departure times,
This calculated parking fee is displayed on the display section 14d based on the display signal f7. When the user (driver) inserts the amount corresponding to the displayed parking fee into the fee input slot 14C and completes the payment, a gate open signal f8 is output to the exit gate operating device 24, and the exit gate 24G is opened. , now it is possible to issue the goods. Reference numeral 26 denotes a second exit vehicle detector consisting of a loop coil or the like provided on the exit side of the exit port 20B. When this detector 26 detects an exit vehicle, a gate close signal f9 is output to the exit gate operating device 24 and the exit is completed. The gate 24G is closed again, and the exit of the vehicle is completed as indicated by arrow PBf.

The above describes the normal exit operation when the correct parking ticket PT is used. Take away the parking ticket PT,
The operation in the case of so-called unauthorized use in which the parking ticket PT is used to cause another vehicle that has already been parked to leave the parking lot will be explained.

The parking ticket PT issued by the parking ticket issuing machine 10 at the time of parking has the entry time and secret number recorded, and the parking ticket PT is recorded at the parking exit 20B as the parking ticket PT is removed. It is stored in the register (memory) of the arithmetic processing unit 14' built in the installed automatic fare adjustment machine 14, and further,
As mentioned above, this stored secret number is deleted by the warehousing confirmation signal f5 output from the second entrance vehicle detector 18, and therefore,
If the vehicle is not parked and only the parking ticket PT is taken out and the vehicle is returned, the parking confirmation signal f5 is not output, so the secret number of the parking ticket PT remains stored in the register.

In this way, the secret number is included in the warehousing condition registration data stored in the register of the arithmetic processing unit 14'.
When an attempt is made to exit a vehicle using a parking ticket PT with a remaining number, the automatic fare adjustment machine 14 checks this secret number, determines that the vehicle ticket PT is fraudulent, and does not calculate the fare. , immediately sends the parking ticket PT back to the reception entrance 14a and refuses to leave the parking lot.

If it is determined that the inserted parking ticket PT is a fraudulent ticket through the verification check above, an alarm or warning light will be lit, or an audio warning will be issued to indicate that the ticket has been fraudulently used. The system may be configured to notify the user and encourage the user to use the correct parking ticket issued at the time of parking.

Next, an example of the detailed configuration of the arithmetic processing unit 14' built into the automatic fare adjustment machine 14 shown in FIG. 1A is as follows.
This will be explained with reference to FIG. 1B.

The arithmetic processing section 14' configured using a microcomputer etc., as shown in the figure, includes an arithmetic control section CPU15a that monitors the overall control;
A data registration register 15b, an input/output port I/Q 15c, a ROM 15d storing the main parts of the flowcharts shown in FIGS. 2A and B and FIG. 3, which will be described later, and a bus 15e. It is configured.

This data registration register 15b includes, for example, a time code registration register 15b1, a secret number.
It is composed of a registration register 15b2, a display code registration register 15b3, and the like. Also, I/Q
As mentioned above, the input port 15c is used to input a parking ticket to the automatic fare adjustment machine 14 in order to settle the fare at the time of leaving the parking lot.
Parking ticket set signal f0 generated when inserting PT,
Registration signal f2 for entry time and secret number, entry confirmation signal f5, parking ticket acceptance start signal for payment machine f6
The display signal f7 and the exit gate open signal f8 are output to the output port.

Therefore, the registration signal f2 from the parking ticket issuing machine 10
When this is input, the storage time is registered in the register 15b1, and the secret number is registered in the register 15b2. Furthermore, when the warehousing confirmation signal f5 is input, the secret number registered in the register 15b2 is deleted. Furthermore, when the parking ticket acceptance start signal f6 is input, each register 15b1, 15
b2 and 15b3 become writeable or readable. Therefore, when you insert the parking ticket PT into the automatic fare adjustment machine 14 to pay the parking fee when leaving the parking lot,
The parking ticket set signal f0 is generated and the register 1 is
5b1 is read out, the difference between this read registration data and the exit time at the time of insertion of this parking ticket PT is calculated by the CPU 15a, and the result is temporarily registered in the register 15b3. It is displayed on the display section 14D as a display signal f7. Also, at this time, the registered contents of register 15b2 are
15a, and when the registration of the secret number is not deleted, the CPU 15a recognizes this and prohibits outputting the gate open signal f8.

The details of the operation at the time of warehousing in the embodiment of the present invention described above are shown in the flowcharts of FIGS. 2A and 2B, and the details of the operation at the time of leaving the warehouse are shown in the flowchart of FIG. The main parts of the flowchart at the time of warehousing and unloading, such as the check for the presence or absence of a secret number in the warehousing registration routine shown in Figure 2B, or the processing of steps S4 to S7 in Figure 3, are programmed and executed in the first step. Shown in Figure B
It is stored in ROM15d.

That is, the vehicle parking process is performed in the order of steps S1→S2→S3→S4→S6→S7 shown in FIG. When the registration process in step S10 shown in B is completed and the receipt is confirmed in step S6, step S11 in FIG. In this case, the secret number is left in the register 15b2 together with the parking ticket number.

On the other hand, the process of leaving the vehicle is executed in the order of steps S1 to S11 shown in FIG. Therefore, in step S7B, it becomes impossible to leave the warehouse.

In the above-mentioned embodiment, the entry time, etc. and secret number are registered in the automatic fare adjustment machine 14 using the registration signal f2 output when the parking ticket PT is issued at the time of parking, but there are many entrances. In the system, the above-mentioned warehousing time and secret
In addition to the number, the parking ticket issuing machine number may also be registered. Further, the secret number registered in the register 15b2 is normally automatically deleted after 24 hours.

Further, in the embodiment, the arithmetic and control unit 14' included in the automatic fare adjustment machine 14 is configured by a microcomputer, but it may also be configured by an ordinary hard logic circuit.

〔effect〕

As explained above, the parking lot management device according to the present invention extracts only the parking ticket issued from the parking ticket issuing machine at the entrance of the parking lot, returns the parking ticket as it is, and uses the parking ticket to park the parking lot. Even if an attempt is made to let a car parked with an illegal parking fee, it can be checked at the time of leaving the parking lot, so such unauthorized use of parking tickets can be reliably prevented. In addition, this secret number is only registered if a parking ticket is fraudulently received without the vehicle being parked in the parking lot, and if the vehicle is officially parked in the parking lot, the registration will be deleted one by one. Since it is possible to downsize the secret number register and simplify the circuit configuration, there is an advantage that the entire device can be manufactured easily and at low cost.
