Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a parking lot management device suitable for managing non-profit parking lots.

(Conventional technology) Token gate systems are used in non-commercial parking lots set up at banks, supermarkets, etc., as it is necessary to limit their use to designated persons such as customers of the store for efficient operation. There are some that are employed. That is, according to this system, a customer can exit the parking lot by using a token received at a predetermined counter inside the store.

However, in such a token gate system, tokens are easily lost, and lost tokens must be frequently replaced, resulting in high costs and fraudulent use due to pseudo-loss. There is a point.
Furthermore, with this system, some customers continue to park for long periods of time even after completing their business at the store, which hinders the efficient operation of the parking lot.

In order to solve these problems with the token gate system, a parking lot management device that uses a password instead of a token is being considered.

In this system, for example, an employee informs the customer of the currently set password using a password setting device installed in the store. When the passenger is informed of the PIN number, he/she enters the PIN number given by the staff member into the departure operation panel near the car gate when exiting the vehicle. The exit operation panel compares the entered PIN number with the PIN number currently set on the setting device, and if they match, releases the car gate and allows the driver to exit the vehicle. By changing the password at arbitrarily set time intervals, unauthorized use by anyone other than the customer is prevented.

(Problems to be Solved by the Invention) However, such conventional parking lot management devices manage passwords based on time, that is, change passwords at preset time intervals.

Therefore, since the same password is valid during that time, there is a risk that someone other than the customer may remember it.

In addition, department stores, supermarkets, etc. that apply such parking lot management devices have extremely large numbers of customers, so in order to be considerate of other customers and to operate efficiently, they have to restrict parking to those who have parked for more than a specified time. collects parking fees according to the excess time, but in this case, the parking fee is collected by the staff at the car gate when leaving the car, and the customer pays the product price and parking fee separately. I had to pay at the location.

The present invention was developed in view of the above circumstances, and the first invention provides a parking lot management device that can reliably prevent unauthorized use by setting an individual PIN number for each customer. The purpose is to In addition, the second invention aims to provide a parking lot management device that has a parking fee calculation function on the PIN setting device side and can pay the parking fee together with the product price at the product price payment location. do.

(Means for solving the problem) For this reason, the first present invention, as shown in Fig. 1, has a car gate that is controlled to open and close when entering and exiting the car, and only authorized persons are allowed to use it. In the parking lot management device according to the present invention, in order to open the car gate when exiting the parking lot, the predetermined person inputs a predetermined PIN number, and the predetermined person enters the PIN number, and the PIN number is notified to the predetermined person. a password setting display device for setting a password, wherein the password setting display device includes a setting means for setting a different password for each predetermined person, and a display means for displaying each set password; When a predetermined person inputs a unique PIN number notified in advance using the PIN input means provided on the entry operation panel, it is determined whether or not the PIN number matches any of the PIN numbers displayed on the display means. A verification means for verifying, a car gate control means provided on the exit operation panel when the entered PIN numbers match, a transmitting means for transmitting a car gate open signal, and a display means when the entered PIN numbers match. The configuration includes a password erasing means for erasing the displayed password.

In addition to the configuration of the parking lot management device of the first invention, the second invention also includes installing a ticket issuing machine that issues a ticket with the time of entry written to a designated person who enters the car near the car gate. , a PIN number setting display device is installed at the product payment place, and an input means for inputting the entry time written on the ticket submitted by a designated person into the PIN number setting display device; A parking fee calculation means that calculates a parking fee according to a parking time calculated based on the time and the current time;
The structure includes an additional transmission means for transmitting calculated parking fee data to an adjacent cash register for product payment.

<Operation> According to the configuration of the first invention, an individual password is set and notified for each customer on the password setting display device, and this is displayed. Then, when the passenger enters his or her PIN number on the departure control panel when exiting the vehicle, the PIN number is sent to the PIN setting display device and the entered PIN number matches one of the displayed PIN numbers. Check to see if there is one. If the combined input password exists, the car gate will be opened. At this time, the display of that PIN number will be erased.

Further, according to the configuration of the second invention, when the entry time of the customer who purchased the product is inputted by the input means, the parking fee calculation means calculates the parking fee according to the parking time, and this data is used to calculate the parking fee according to the parking time. It is transmitted to the cash register for settlement. Therefore, customers can pay for products and parking fees on the spot, saving them the trouble of paying these at separate locations.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 2 shows the overall configuration of an embodiment of the first invention.

In the figure, this parking lot management device includes a PIN number setting display device 2 that sets and displays a PIN number for each customer, and a PIN number setting display device 2 that sets and displays a PIN number for each customer, and a Entrance control panel 3 for directly inputting the unique PIN number given by the staff
and a vehicle body detector 4 composed of first and second loop coils L ₁ and L ₂ buried separately at the entrance/exit of the parking lot; The vehicle is equipped with a car gate 5, etc., which is composed of a cutoff bar that is controlled to open and close. Incidentally, a sub-display device 6 is connected to the password setting display device 2, which is installed at a CD corner in a bank, for example, and displays the password only during unmanned service hours. Furthermore, a known signal light 7 is installed near the exit operation panel 3 to indicate whether the parking lot P is "full" or "vacant."

The PIN setting display device 2 has a function key 11 for selecting various function modes, such as whether to automatically or manually set the PIN for each customer, and a manual PIN setting mode. When specified, a numeric keypad 12 is provided for keying in the password, and a display 13 is provided as a display means for displaying the actually set function mode and password for each customer. . Furthermore, the function key 11 and the display 13
More specifically, as shown in FIG. 3, the function key 11 is provided with mode setting keys such as call and standby in addition to automatic and manual setting of the password. The display 13 includes a function mode display section 13a and a password display section 13b that displays in advance the password that has been set for each customer and the password for the next customer. When in standby mode, the PIN number for the next customer ("576" in the figure) is displayed in advance at the bottom of the PIN display section 13b, and when a customer comes, the user can enter the displayed PIN number. After informing the PIN number, by operating, for example, a push-type call switch 14 provided in the PIN display section 13b, the PIN number will be shifted to the display section above which displays the PIN number that has already been set, and the PIN number will be registered. It's summery. Also, when in the call mode,
The PIN number for the next customer ("575" in the figure) is not displayed at the bottom of the PIN display section 13b.
When a customer arrives, the password is displayed for the first time by operating the call switch 14, and after informing the customer, by continuing to operate the call switch 14, the password is shifted to the already set PIN code display area above it. It is becoming more and more like this. The call switch 14 may be of a foot type that can be operated with a foot, in addition to a push type.

The PIN setting display device 2 is placed at a designated counter in the store so as not to be seen by customers, and customers using the parking lot P must enter their PIN number. You will be notified verbally or by memo from store staff.

The exit operation panel 3 includes a PIN key 15 as a PIN input means for customers exiting the parking lot P to input their PIN number, and a PIN key 15 to confirm that a predetermined number of digits of the PIN number have been input. It has a monitor 16 that displays marks such as dots or bars in a number corresponding to the number of digits of the number.

FIG. 4 shows the electrical configuration of the device according to the present invention, and the password setting display device 2 has a first CPU 20 using a microprocessor. The first CPU 20 is connected to a function key 11 and a numeric keypad 12.
Based on the input data from the ROM 21 and the information read from the ROM 21, a personal identification number for each customer is set and displayed on the display 13 and stored in the RAM 22. In addition, the first CPU 20 is the entry operation panel 3.
It is connected to a data transmitter/receiver 23 as a transmission means, which is composed of a transmission control LSI that transmits data to the exit operation panel 3 side and receives data from the exit operation panel 3 side. You have received a unique PIN and this PIN is currently
It checks whether it matches any of the PIN numbers stored in the RAM 22 (displayed on the display 13), and if it matches, it sends an opening signal for the car gate 5 to the exit operation panel 3 side. . At this time, enter the matched PIN on the PIN display section 13.
Delete from b. Furthermore, the first CPU 20 includes a timer circuit 2 comprising a digital switch or the like for counting the validity period of the set PIN number.
Connected to 4. Therefore, the first CPU 20 corresponds to a setting means, a verification means, and a password erasing means. Incidentally, the ROM 21 stores a control program for the first CPU 20 as well as numbers having an arbitrary number of digits (eg, 2 digits) in an arbitrary order (eg, 100) in a random order.

The entry control panel 3 is connected to the ROM 29 and RAM 30 and uses a microprocessor.
The second CPU 28 transmits the password input by the customer to the data transmitter/receiver 23 of the password setting display device 2 via the transmission line 25, and receives a car gate opening signal from the data transmitter/receiver 23. It is connected to a data transmitter/receiver 26 composed of a transmission control LSI, and opens the car gate 5 when a car gate open signal is input. Also, the
2CPU 28 is a PIN key 1 which serves as a PIN input means for the user to enter his/her PIN number.
5 is connected. Furthermore, when the second CPU 28 receives an abnormality alarm output from the PIN setting display device 2 side, which is sent when the verification mismatch circuit exceeds a predetermined limit number of times, the second CPU 28 is configured with a warning light with synthesized audio, an intercom, etc. A signal is output to activate the alarm unit 31 that has been activated, and the manager's room 32 is notified to that effect. Here, the second CPU 28 corresponds to the output of the car gate means. In addition, ROM29 has the
A control program for the 2CPU 28 is stored.

The sub-display device 6 is a data receiver 33 configured with a transmission control LSI for receiving the password transmitted from the data receiver 23 via the transmission line 25.
a display surface 6a that displays the received PIN number;
has. Note that the password transmission performed between the data transmitter/receiver 23 and the data receiver 33 involves response confirmation (double transmission verification + return verification) as described below.
Depends on the method. That is, first, when a password is sent from the data transmitter/receiver 23 to the data receiver 33, the data receiver 33 returns the number to the data transmitter/receiver 23. Next, the data transmitter/receiver 23 uses a register (not shown) to check and compare the initially transmitted number and the number returned from the data receiver 32, and only in the case of a match, sends the said number. The data is retransmitted to the data receiver 33. With this method, the password is transmitted from the password setting display device 2 to the sub-display 6 without any errors.

Next, the operation of this embodiment when entering and leaving the parking lot P will be explained based on the flowcharts of FIGS. 5 and 6.

First, when entering the vehicle, after confirming that the vehicle is empty using the signal light 7, the user enters the vehicle (in the direction of the dashed arrow in Figure 2) and enters the parking lot P as shown in Figure 5. Entrance begins.

When the car A approaches the car gate 5, the first loop coil _L1 operates to detect the entry of the car A, and the car gate 5 opens. Then, when the car A passes through the car gate 5, the second loop coil L ₂
As a result of this operation, passage of the rear end of the car A is detected, and the number of parked cars is added at the same time as the car gate 5 is closed.

On the other hand, at the time of departure, as shown in Figure 6, car A that started to depart temporarily stops in front of the departure control panel 3, and the customer enters his/her PIN number given at a designated counter in the store. Input using the password key 15. At this time, if the password entered by the customer does not match the password stored on the entry operation panel 3, the customer is guided to input the password again. Re-entering the PIN number is allowed up to a predetermined number of times (for example, 3 times), and if the password is re-entered a predetermined number of times, the warning light of the alarm unit 31 will turn on and you will be prompted to contact the manager's office 32 using the interphone. Ru.

If the entered password matches the stored password, the car gate 5 opens, and when the car A passes through the car gate 5, the second loop coil
When L ₂ operates and the passage of the rear end is detected,
Car gate 5 closes. At this time, the first loop coil _L1 operates to detect the car A, thereby subtracting the number of parked cars.

Next, the password setting operation of the password setting display device 2 will be explained with reference to FIG.

In step 1 (indicated by S in the figure and the same applies hereinafter), initialization is performed.

In step 2, it is determined whether the communication state between the data transceivers 23 and 26 is normal. When it is determined that the communication state is abnormal (NO), if there is a transmission error, it is processed (step 3), an alarm is issued, and recovery processing is performed (steps 4 and 5). Note that this communication status check is constantly performed while the device is operating. If the communication state is determined to be normal, the process advances to step 6.

In step 6, by operating the function key 11, you can select automatic or manual password setting.
Configure function modes such as call and standby selection.

In step 7, it is determined whether the password setting is automatic mode or manual mode. If the mode is manual, proceed to step 8, and use the numeric keypad 12 to manually input the password. If the automatic mode is selected, the process proceeds to step 9, where it is determined whether the mode is call mode or standby mode. When in standby mode, the password to be given to the next customer is displayed at the bottom of the password display section 13b (step 10).

In such a state, if the customer asks the staff for the PIN number, in automatic mode and call mode, the flow from step 12 onwards is executed, and when the staff presses the call switch 14 (step 12), the timer starts ( Along with step 13), a password is displayed at the bottom of the password display section 13b (step 14), and the staff informs the customer of this password. If the staff member presses the call switch 14 again before the predetermined period of time has elapsed, the PIN will be entered in the personal PIN registration area at the top of the PIN display area 13b that displays the previously set PIN. Shift (steps 15-17). here,
When the call switch 14 is not pressed again within a predetermined time, the password is automatically shifted to prevent the same password from being given to multiple customers.

In addition, in the case of automatic mode and standby mode, the PIN number to be given to the customer is already displayed, and after the staff tell the customer the PIN number,
Press call switch 14 (step 11). As a result, the PIN number is shifted to the personal PIN registration section (step 17), and the next PIN number is automatically displayed in advance at the bottom of the PIN display section 13b. In addition, in manual mode, except for the PIN code being manually entered by the staff member using the numeric keypad 11,
Other operations are performed as in automatic mode.

In step 18, the password setting display device 2
The system waits for the password to be entered from the entry operation panel 3 side, and when the password is input, the process proceeds to step 19.

In step 19, the input PIN is checked to see if it matches any of the currently set PINs, and if they match, the PIN is deleted from the PIN display section 13b in step 20. At the same time, in step 27, a car gate open signal is output to the entry operation panel 3 side.

In step 22, it is determined whether all registered PIN numbers have been erased, and if they have been erased, the process ends. Also, if the PIN numbers do not match in step 19,
The process proceeds to step 23, where the number of discrepancies is determined, and if the number of discrepancies is greater than a predetermined value, an alarm signal is output to the participation operation panel 3 in step 24.

Next, the car gate opening control operation of the exit operation panel 3 will be explained based on FIG.

In step 31, initialization is performed.

In step 32, it is determined whether the mode is the PIN number mode, that is, whether the car gate 5 can be opened by the PIN number input by the customer.
If you are in PIN code mode, proceed to step 33.

In step 33, when the customer enters a PIN, the PIN is sent to the PIN setting display device 2, and in step 34, the monitor 16 displays the number of marks corresponding to the number of digits in the PIN. to confirm entering the PIN.

In step 35, it is determined whether or not a matching signal has been input from the PIN setting display device 2 based on the transmitted PIN. If a matching signal has been input, the process proceeds to step 36, and the PIN setting display device 2 The car gate 5 is controlled to open based on the car gate opening signal from the car gate opening signal.

Further, if a matching signal is not input, a message indicating that the key must be input again is displayed, and the customer re-enters the password in step 37.

In step 38, it is determined whether an alarm signal has been input from the password setting display device 2 or not. When the alarm signal is input, a warning light is turned on in step 39 and an alarm is sent to the manager's room 32 to warn of abnormal operation, and in step 40, the operation of the participation operation panel 3 is temporarily stopped. Then step 41
Then, it is determined whether or not the operation of the entry operation panel 3 should be restarted after appropriate processing is carried out. If it is determined that the operation should be restarted, the process proceeds to step 42 in the same way as after the car gate opening control operation in step 36, and the operation of the device is restarted. Operation in the password mode continues until a decision to stop is made.

On the other hand, if it is determined in step 32 that the mode is not the password mode, the process proceeds to step 43, where the master number is keyed in by the staff member, and the entered master number is compared with the preset master number in step 44. If they match, the process proceeds to step 36 and the opening control of the car gate 5 is executed. If there is a mismatch, key-in the master number again.

In this way, if we set a different PIN number for each customer and allow them to leave the parking lot P only with their unique PIN number, it would be possible to manage PIN numbers based on time, as in the past. There is less worry that someone else will remember the parking lot compared to the other method, and it is possible to reliably prevent unauthorized use of the parking lot.

Next, the second idea will be explained.

This is suitable for places such as supermarkets and department stores where there are a large number of users and where parking fees are collected for parking for more than a certain amount of time in order to efficiently operate the parking lot. By connecting to the cash register at the cashier counter where the product price is paid, and paying the parking fee along with the product price at the cashier counter, you can leave the parking lot without having to pay the parking fee. It has been made possible.

FIG. 9 shows the overall configuration of an embodiment of the second invention.

In the figure, the parking lot P side is equipped with a ticket issuing machine 17 that issues blank tickets or magnetic cards on which the entry time of users entering the car is written in front of the car gate 5. The configuration is similar to the embodiment of the first invention.

On the other hand, a PIN number setting display device 4 installed in the store
0 includes a function key 41, a numeric keypad 42, and a display 43 similar to the above-mentioned PIN setting display device 2, as well as a card reader 44 for reading the entry time from a magnetic card issued by the ticket issuing machine 17.
and a printer 45 for printing parking fees and the like. This PIN number setting display device 40 is installed at the cash register counter where customers pay for products purchased, and is connected to a cash register 46 to cash out parking fee data calculated from the difference between the entry time and the current time. It is transmitted to register 46. The cash register 46 collects the amount together with the product price. Note that it is preferable to provide a plurality of dedicated counters to distinguish them from a checkout counter that only pays for regular products. In addition, ticket issuing machine 1
If 7 issues blank tickets, the magnetic card reader 44 is not necessary.

FIG. 10 shows the electrical configuration of the password setting display device 40. Note that the electrical configuration of the entry operation panel 3 is the same as that shown in FIG. 3, so a description thereof will be omitted.

In the figure, the PIN number setting display device 40
is a CPU51 using a microprocessor.
has. The CPU 51 is connected to a function key 41, a numeric keypad 42, and a call switch 47, and sets a different password for each customer based on input data from the keys 41 and 42 and information read from the ROM 52. It is displayed on the display 43 and stored in the RAM 53. Further, the CPU 51 exchanges the set password with the entry operation panel 3 via the data transmitter/receiver 54 constituted by a transmission control LSI, and also transmits the information to the sub-display 6. Also, CPU
51 is a timer circuit 5 composed of a digital switch, etc. for counting the validity period of the PIN number.
5. Furthermore, the CPU 51 is connected to a card reader 44 as an input means, calculates the parking fee from the difference between the entry time read by the card reader 44 and the current time of the timer circuit 55, and calculates the parking fee from the connected cash register 46. to be transmitted. At this time, the parking fee is printed out using the printer 45 connected to the CPU 51. The functions of the password setting display device 40 of this embodiment are the same as those of the password setting display device 2 described above, except for the parking fee calculation function.

As shown in FIG. 11, the operation of the parking lot management device having such a configuration at the time of entry is as follows: When the first loop coil _L1 detects the entry of the car A, the ticket issuing machine 17 writes the entry time. A magnetic card will be issued. The passenger receives this and the car gate 5 opens. After that, as in FIG. 5, when the car A passes through the car gate 5, the passage of the rear end of the car A is detected by operating the second loop coil _L2 .
The number of parked cars is added at the same time as the car gate 5 is closed.

Furthermore, the operation when leaving the vehicle and the exit/entry control operations of the password setting display device 40 and the exit operation panel 3 are the same as those of the previously described embodiment shown in FIGS. 6 to 8.

Next, the first step is to explain the fee settlement process using the PIN setting display device 40 and the cash register 46.
This will be explained according to the flowchart shown in FIG.

First, when a customer presents a magnetic card (step 51), the clerk operates a function key (step 52). In this operation, the customer selects a mode such as discount or free parking fee, and selects whether to operate the set key provided on the numeric keypad 42, etc., depending on the customer.

Next, the attendant inserts the presented magnetic card into the card reader 44 (step 53), and if the time of entry is read from the magnetic card (step 54), SET key operation is selected in the function key operation. If so, the staff operates the set key (step 55). If no set key operation is selected, this operation is not necessary. This set key is used to confirm that the entry time has been entered correctly.

Next, the parking fee is calculated based on the difference between the entered entry time and the current time in the internal timer circuit 55, the mode selected with the function key, etc. (step 56), and the calculated parking fee is The data is transmitted to cache register 46 (step 57).

In step 58, the parking fee is added to the price of the product purchased by the customer based on the parking fee data transmitted by the cash register 46, and the process proceeds to step 59.
Then, the product price and parking fee are settled all at once, and when the settlement is completed, the clerk enters the PIN number if it is displayed in standby mode, or by operating the call switch 47 if it is in call mode. Inform the customer of the displayed PIN (step
60).

The customer can exit the parking lot using the personal identification number set for his/her own use.

If you use a blank card with the time of entry printed on it instead of a magnetic card, steps 53 and 54 in the fare settlement process shown in Figure 12 will be changed. Steps 61 to 63 are indicated by broken lines.

That is, after the function key operation is completed, in step 61, the attendant enters the entry time printed on the blank ticket using the numeric keypad 42, and in step 62, the input is confirmed according to the entry time displayed on the display 43. make sure it's correct. If the input is incorrect, the clear key provided on the numeric keypad 42 is operated in step 63 to perform the input operation again. If correct, proceed to set key operation or parking fee calculation operation.

According to this configuration, the customer can pay the parking fee together with the product price at the cash register counter, and it is no longer necessary to make the customer pay the product price and the parking fee twice at different locations as in the past.

In order to make effective use of the parking lot even when the store is on holidays, a coin selector may be installed so that on holidays the customer can open the car gate by inserting a coin and informing the customer of the password.

<Effects of the invention> As explained above, according to the first invention, since a different PIN number is set for each customer, it is easier for others to remember the PIN number than with a method in which the PIN number is changed over time. There is less worry about parking being stolen, illegal long-term parking can be more reliably prevented, and the parking lot can be operated more efficiently.

In addition, according to the second invention, the PIN setting display device is connected to the cash register, the parking fee is added to the product price, and the payment is made at a cash register counter etc. This is convenient for customers as they do not have to pay twice at different locations.
