Connected, the LED 142 displays the operating state of the portable terminal 130, and the like.

Hereinafter, the effect of the parking meter configured as described above and its use method will be described.

Fig. 12 is a flowchart showing the IC card use operation procedure of the parking meter according to the present invention, in which S denotes a step.

First, when the 12V voltage supplied from the main battery 52 in the parking meter is converted into a voltage required for driving the microprocessor 100 through the first voltage regulator 112 and input to the controller 80, the microprocessor ( In 100), the parking meter is initialized as follows.

That is, when there is no parking vehicle, the red LED 33 of the parking vehicle display unit 21 is turned on, and the microprocessor 100 is operating in a power saving mode by the power down circuit 102, and other than the RTC 92. Peripheral circuits are also operating in power saving mode (S1, S2).

At this time, when the user parks the parking vehicle in the parking space and inserts the IC card into the IC card reader / writer 1 (S3), the IC card reader / writer 1 detects the input of the IC card to detect the IC card. An interrupt is generated to the microprocessor 100 through the reader / writer connection 72.

Therefore, when the power saving mode of the microprocessor 100 is released and the stored data of the IC card is input into the parking meter through the IC card reader / writer 1, the IC card is damaged and stored in the microprocessor 100. It is determined whether the number data cannot be read (S4).

If the IC card is a damaged card (YES), the microprocessor 100 releases the power saving mode of the voice output unit 90 to inform the user of the state of the card damage through the voice output unit 90 and the LCD 13. After returning to the initialization state (S5).

On the other hand, if the IC card is not a damaged card (NO), the microprocessor 100 checks the amount of charge of the IC card to determine whether there is amount of charge data (S6).

If there is no charge data on the IC card (NO), the microprocessor 100 notifies the user that there is no charge data on the IC card through the voice output unit 90 and the LCD 13, and then returns to the initialization state. (S7)

On the other hand, if there is money data charged in the IC card (YES), the microprocessor 100 determines the left / right confirmation switches 27 and 29 according to the position of the parking vehicle through the voice output unit 90 and the LCD 13. Tells you to press one (S8).

Therefore, the user selects and presses one of the left / right confirmation switches 27 and 29 according to the guide information. The microprocessor 100 is configured to switch the left / right confirmation switches 27 and 29 through the switch connection unit 78. It is determined whether it is on (S9).

If the user removes the IC card without pressing the left / right confirmation switches 27 and 29, the parking meter returns to the initialization state.

When the user presses the left / right confirmation switches 27 and 29 according to the guide information, the parking meter starts to operate. The microprocessor 100 reads the IC card closing time (current time of the parking meter) from the RTC 92. After that, write it on the IC card (S10).

Thereafter, the microprocessor 100 reads the unique number of the IC card and stores it in the memory unit 110. (The stored card unique number is stored for a predetermined time when the IC card is reinserted and parking is not normally terminated. It is deleted from the department, and when all the amount of charge is used before re-inserting the IC card, and also when the parking is normally completed due to the re-insertion of the IC card.)

Subsequently, the microprocessor 100 checks whether the read unique number of the IC card is among the card numbers previously stored in the memory unit 110, so that the unique number of the IC card is among the numbers stored in the memory unit 110. If not, it is regarded as starting parking for the first time, and if the unique number is among the numbers stored in the memory unit 110, it is regarded as a case of ending parking by re-inserting the IC card. (S12)

If the unique number of the IC card read by the microprocessor 100 is not stored in the memory unit 110, the red LED 33 of the parking vehicle display unit 21 is turned off and the green LED 35 is turned on to park the vehicle. Indicates that area is in use (S13).

Subsequently, the microprocessor 100 checks whether the IC card is a general card or a resident card by reading the card number, and if the resident card is YES, reads data of one address from the period data stored at two addresses. After the data is stored in the memory unit 110, the value stored in the IC card is erased. (S14, S15)

On the other hand, in the case of a normal card (NO), data of one address is read out of the used amount data stored in two addresses, stored in the memory unit 110, and the value stored in the IC card is deleted (S16, S17).

The IC card has a address to store at least six data as follows.

① Address number 1 is stored.

Residential Area Use No.: Set the period of use in the residential area.

General Area Use Number: Charge the amount when using the product outside the residential area.

Handicapped person, light car number: Parking fee discount

② Addresses 2 and 3 store the period data for residential use.

③ Address data 4 and 5 are saved when using general area.

④ Number 6 is entered when parking starts.

⑤ The microprocessor 100 reads the period data or the amount data from 2 or 4 of the card data according to the usage area among the 2, 3, 4 and 5 addresses.

⑥ When the microprocessor 100 reads the card data, the parking process starts when the 2, 3 or 4, 5 address is the same data value.

⑦ If the parking lot tries to park in another parking area without re-entering the IC card in one place, the parking meter does not start the parking process because the 2, 3 (or 4, 5) have different values. Send a message to In this case, if there is a large amount of remaining period or amount at No. 2 or No. 4, recharge the remaining period or amount at No. 2 or No. 3 or No. 4 or 5 except for a certain amount of fine.

Next, the microprocessor 100 calculates the available parking time from the data read from the IC card and informs the user of the available time through the voice output unit 90 and the LCD 13. (S18, S19, S20)

Thereafter, the microprocessor 100 transmits a message to the user to remove the card through the voice output unit 90 and the LCD 13, and the user removes the card.

After parking is started, the microprocessor 100 detects the presence of a vehicle by operating the ultrasonic sensors 17 and 19 at regular intervals. When there is no vehicle, the microprocessor 100 assumes that the user leaves the vehicle without reinserting the IC card. 35 is extinguished and the red LED 33 is turned on to indicate that parking is possible. (S22, S23)

Subsequently, when the user leaves the IC card without reinserting the IC card, the IC card data stored in the memory unit 110 is stored for a predetermined time and then deleted. That is, if the parking period or the amount of data stored in the memory unit 110 is subtracted into the parking meter without the IC card reinserted and becomes '0', the stored data in the memory unit 110 is stored in the memory unit ( And the parking meter is initialized (S24, S25).

On the other hand, when there is a vehicle, it is checked whether the parking time has been exceeded, and when the parking card is not exceeded, the parking meter returns to the initializing state (S27).

Even when the parking time is exceeded, if the parking vehicle is detected in the parking space by the ultrasonic sensors 17 and 19, the green LED 35 is turned off and the red LED 33 is turned on to indicate that the parking is possible. Wirelessly transmits parking violation information to the manager's portable terminal 130 through 94. (S28, S29, S30)

Therefore, the portable terminal 130 displays the parking violation information on the LCD 13 and the sound through the speaker 134, so that the parking manager processes.

If the card unique number is among the numbers stored in the memory unit 110 in step S12, it is regarded as a case where parking is terminated by reinserting the IC card. When the IC card is reinserted, the processes from steps S4 to S11 are repeated. do.

If the read card number is in the data stored in the memory unit 110, the microprocessor 100 reads the parking start time input to the card at the start of parking, and if the green LED 35 is turned on, the green LED 35 is displayed. The lights are turned off to turn on the red LED 33 (S31, S32, S33).

Subsequently, the microprocessor 100 checks the stored data, reenters the remaining available period into the card if the resident card is YES, and deletes the card number stored in the memory unit 110 (S34, S35, and S36). )

On the other hand, if the normal card (NO), the parking fee is calculated from the parking start time data read from the card and the current time data read from the RTC 92, and then the parking fee is subtracted from the amount data stored in the memory unit 110. The card number stored in the memory unit 110 is deleted after inputting the amount address of the IC card.

At this time, the parking time is calculated as a normal rate on weekdays, and discounted rates are applied to nights, Saturday afternoons, public holidays, statutory holidays, the handicapped, and light cars.

Subsequently, the microprocessor 100 notifies the remaining available period to the resident card user through the voice output unit 90 and the LCD 13, and initializes the parking meter after notifying the remaining available amount to the general card user. S39)

Thereafter, the microprocessor 100 transmits a message to the user to remove the card through the voice output unit 90 and the LCD 13, and the user removes the card.

After leaving the parking vehicle, the microprocessor 100 detects the presence of the vehicle by operating the ultrasonic sensors 17 and 19 at regular intervals, and if the vehicle continues to be detected for a predetermined time, the parking vehicle is parked without an IC card. Recognized as a parking vehicle, and transmits the unauthorized parking vehicle information to the manager's portable terminal 130 by using the FM wireless transmitting and receiving unit 94 while there is an unauthorized parking vehicle, and transmits periodically until the manager receives and processes it. (S41, S30)

Accordingly, the portable terminal 130 receives the unique number of the parking meter and displays the unique number and "unauthorized parking" on the LCD 132 screen, and generates a voice message through the speaker 134 to display the unauthorized parking vehicle information. The parking manager will take care of it.

On the other hand, when an unauthorized parking vehicle leaves, an IC card is inserted into a parking meter, or cash is input, the sending of the unauthorized parking vehicle information is stopped.

Next, a description will be given of how to use the parking meter for cash input.

FIG. 13 is a flowchart showing the cash flow operation procedure of the parking meter according to the present invention, in which S denotes a step.

First, when the 12V voltage supplied from the main battery 52 in the parking meter is converted into a voltage required for driving the microprocessor 100 through the first voltage regulator 112 and input to the controller 80, the microprocessor ( In 100), the parking meter is initialized as follows.

That is, the red LED 33 of the parking vehicle display unit 21 is turned on when there is no parking vehicle, the microprocessor 100 is operating in a power saving mode by the power down circuit 102, and other than the RTC 92. Peripheral circuits are also operating in the low power mode (S51, S52).

In this case, when the user parks the parking vehicle in the parking space and then puts a coin or a bill into the coin recognizer (3) or the bill recognizer (7) (S53), the coin recognizer (3) or bill recognizer (7) The input of the bill is sensed to generate an interrupt in the microprocessor 100 through the coin recognizer connection 74 or the bill acceptor connection 76.

Therefore, the power saving mode of the microprocessor 100 is released so that the microprocessor 100 reads the input value data into the parking meter through the coin acceptor connector 74 or the bill acceptor connector 76.

Damaged coins are automatically returned upon coin input, and the microprocessor 100 calculates the parking time while accumulating the input amounts and displays them on the LCD 13. (S54, S55, S56, S57)

In addition, damaged banknotes are automatically returned when the banknotes are inserted, and the microprocessor 100 calculates the parking usage time while accumulating the amounts of money inputted and displays them on the LCD 13 (S58, S59, S56, S57).

At this time, when the cancel switch 31 is pressed, all of the input amount is returned to the cash return port 11. (S60, S61)

When the charge is completed, (if YES), the microprocessor 100 presses one of the left / right confirmation switches 27 and 29 according to the position of the parking vehicle through the voice output unit 90 and the LCD 13. (S62)

Therefore, the user selects and presses one of the left / right confirmation switches 27 and 29 according to the guide information. The microprocessor 100 is configured to switch the left / right confirmation switches 27 and 29 through the switch connection unit 78. It is determined whether it is on (S63).

If the user presses the cancel switch 31 without pressing the left / right confirmation switches 27 and 29, the parking meter returns to the initial state.

When the user presses the left / right confirmation switches 27 and 29 according to the guide information, the parking meter starts to operate. The microprocessor 100 parks the remaining amount and the amount of cash input if there is a remaining amount in the parking meter. The red LED 33 of the parking vehicle display unit 21 is turned off and the green LED 35 is turned on while calculating the possible time and notifying the available parking time through the voice output unit 90 and the LCD 13. Indicates that it is in use. (S64 ~ S68)

After parking is started, the microprocessor 100 operates the ultrasonic sensors 17 and 19 at regular intervals to detect the presence of a vehicle, and when there is no vehicle, the microprocessor 100 regards it as leaving the vehicle and the green LED 35 turns off and the red LED ( 33) On to indicate that parking is possible. (S69, S70)

During the use, if additional charges are added, the additional use time and the remaining time are added to inform the available time through the voice output unit 90 and the LCD 13, (S70) at the end of the use time green LED (35) ) Is turned off, the red LED 33 is turned on to initialize the parking meter. (S71, S72, S73)

After the end of the use time, the microprocessor 100 operates the ultrasonic sensors 17 and 19 at regular intervals to detect the presence of the vehicle, and if the vehicle is continuously detected for a predetermined time, the parking vehicle is parked without unauthorized cash. Recognizing and transmitting the unauthorized parking vehicle information to the manager's portable terminal 130 using the FM wireless transmitting and receiving unit 94 while the unauthorized parking vehicle is present, it is periodically transmitted until the manager receives and processes it. S75)

Accordingly, the portable terminal 130 receives the unique number of the parking meter and displays the unique number and "unauthorized parking" on the LCD 132 screen, and generates a voice message through the speaker 134 to display the unauthorized parking vehicle information. The parking manager will take care of it.

On the other hand, when an unauthorized parking vehicle leaves, an IC card is inserted into a parking meter, or cash is input, the sending of the unauthorized parking vehicle information is stopped.

Next, a description will be given of a portable terminal for receiving the information of the parking meter wirelessly or by wire.

First, when the information of the parking meter is wirelessly transmitted from the FM wireless transmitter / receiver 94, the antenna 138 of the portable terminal 130 receives the sound through the speaker 134 and displays the information on the LCD 132 screen. Parking Manager will take care of it.

① In the event of a breakdown of the parking meter, a unique number of the parking meter is received, and a unique number and "failure" are displayed on the LCD 132 screen and a voice message is generated.

② When the battery is discharged, the unique number of the parking meter is received, the unique number and 'battery exchange' are displayed on the LCD 132 screen, and a voice message is generated.

③ In the case of unauthorized parking, a unique number of the parking meter is received, the unique number and "unauthorized parking" are displayed on the LCD 132 screen, and a voice message is generated.

Then, when the connector 140 of the portable terminal 130 and the terminal connection portion 96 of the parking meter are connected, the accumulated amount and use time of the parking meter, the stored information that has been transmitted, and the parking meter state check information are downloaded.

In addition, the portable terminal 130 is connected to the management computer 150 to transfer the information received wirelessly from the parking meter and the information received by the connector 140 to the computer 150.

Accordingly, the computer 150 downloads the information of the portable terminal 130, downloads the information of the wireless repeater, and classifies the downloaded information into a database to increase management efficiency.

On the other hand, when the IC card key, which is separate from the IC card used for parking, is inserted into the IC card reader / writer 1, the IC card reader / writer 1 detects the input of the IC card key and the IC card. An interrupt is generated to the microprocessor 100 through the reader / writer connection 72.

Therefore, the microprocessor 100 drives the cash return / storage and the parking meter opening and closing solenoids 48 and 50 through the cash return / storage and door opening / closing connector 98 to open the door of the parking meter. It can increase.
