Description

Passenger location recognition device and method in contactless payment

The present invention relates to an apparatus and method for recognizing a passenger's location during contactless payment, and in particular, in a non-contact (tagless) gate, a user terminal is measured outside and inside a gate, respectively, and received signal strength indication (RSSI) of a signal for each location measured. and a passenger location recognition device and method for non-contact payment, which can prevent payment errors by accurately recognizing a passenger location based on passenger detection information detected using a passenger location sensor installed inside a gate.

Recently, instead of a physical ticket such as paper or a magnetic card, a user who has a wireless terminal device installed with an app that can process payment, such as a smartphone, places the wireless terminal device on the device for payment (tagging) The 'mobile ticket' service, which pays for the fare, is widely used.

That is, a method of tagging a transportation card when getting on or off a vehicle such as a subway or a bus or passing through a gate is widely used. As for the transportation card tag method, the NFC (Near Field Communication) method is mainly used, and most of them use the short-range wireless communication method, and the recognition distance of the transportation card is short.

Generally, it is common for the user's transportation card to be recognized only when the user's transportation card is at a distance of about 5cm from the transportation card terminal in the vehicle. It is quite inconvenient to tag. In this case, put down the luggage for a while near the transportation card tag device and take out the transportation card and tag it, or take off the gloves for a while near the transportation card tag device and then take out the transportation card and tag it. There is a delay in passing through the gate.

In order to solve the inconvenience of such a tagging method of payment, a newly proposed method is a contactless (tagless) method of payment.

In such a contactless payment method, an application for payment is installed on a user's mobile device, etc., and the payment is performed in a contactless manner through short-range wireless communication and sensing through a sensor using the payment application.

In this contactless payment method, when passengers pass through the gate, there is no problem as long as passengers pass in one direction by keeping a certain distance in a line and keeping a certain distance. If a situation such as multiple passengers entering from one direction at the same time, or the person in front enters the gate first with the person in front recognized, a payment error occurs due to the correct recognition of the entrant or an error in location recognition. , there is also a problem with gate control.

Therefore, there is a demand for a non-contact payment technology that accurately recognizes a passenger's location even in various situations as described above and enables payment to be made in the order of entry of the passenger.

The "apparatus and method for recognizing a passenger's location during contactless payment" according to a preferred embodiment of the present invention configured as described above will be described in detail as follows.

First, a passenger who wants to use a tagless gate such as a subway enters a beacon (which may be a two-way beacon) signal reception area of a subway station using the passenger terminal 200 , which is a mobile device in which a tagless payment app is installed. Here, the tagless gate is described as a subway gate, but this is only an embodiment for convenience of description, and the present invention is applied to all gates (eg, bus boarding and disembarking gates, building access control gates, etc.) using tagless gates. can be applied.

When the passenger terminal 200 enters the beacon signal reception area of the subway station, it receives a signal transmitted from a beacon installed in the subway station, and automatically activates the installed tagless payment app when the beacon signal is received (S101 - S102) .

When the tagless payment app is activated, payment card information and identification information (eg, ID) for identifying the passenger terminal 200 are transmitted to the payment server 300 as passenger information for fare payment.

The payment server 300 reads payment card information and ID information for passenger identification through the passenger information and temporarily stores them in the database (S103 and S104).

In addition, as shown in FIG. 2A , a passenger carrying a passenger terminal 200 that activates the tagless payment app and transmits passenger information, enters and exits the gate formed by the first and second gate bodies 101 and 102 . Upon entering (10), the passenger terminal 200 is connected through the two Bluetooth modules 111 and 112 of the first Bluetooth module 110 having directivity to obtain passenger information (ID, payment card information). do. The passenger information thus obtained is transmitted to the main control board 150 in real time through user datagram protocol (UDP).

Here, the two Bluetooth modules 111 and 112 are paired to obtain two pieces of passenger information for the same passenger, and the main control board 150 extracts a reception sensitivity (RSSI1) from the received two pieces of passenger information, and Only passenger information with good reception sensitivity (large) is used for control. In this case, when the passenger carries the passenger terminal 200 in his right hand or right pocket, or in his left or left pocket, or when Bluetooth is installed on only one side, transmission and reception of Bluetooth signals may be disturbed by the human body or other interfering factors. In order to increase accuracy, Bluetooth is installed in pairs on both sides of the gate.

The main control board 150 temporarily stores payment card information and ID information included in the passenger information obtained through the first Bluetooth module 110 (S105 - S106).

Here, the main control board 150 uses the pair of passenger detection sensors 161 and 162 for recognizing the first passenger position in the first passenger position detecting unit 160. If a passenger is not detected, payment processing waits. do.

Next, the passenger continues toward the gate entrance 10, and when the entrance is made to some extent toward the entrance 10, the passenger information is recognized again by the second Bluetooth module 120 installed inside the gate.

Here, two Bluetooth modules 121 and 122 are installed in pairs to face the second Bluetooth module 120 at the same location on both sides around the gate.

Through the two Bluetooth modules 121 and 122 of the second Bluetooth module 120 having directivity, it connects with the passenger terminal 200 to obtain passenger information. The passenger information thus obtained is transmitted to the main control board 150 in real time through user datagram protocol (UDP) (S108).

The main control board 150 acquires two pieces of passenger information for the same passenger through the two paired Bluetooth modules 121 and 122, but as is well known, the reception sensitivity (RSSI2) is By comparing the extracted reception sensitivity (RSSI2) and the reception sensitivity (RSSI1) obtained through the first Bluetooth module 110, passenger information satisfying the condition is used for payment processing. Here, the condition is satisfied when the reception sensitivity RSSI2 is greater than the reception sensitivity RSSI1 by comparing the reception sensitivity of the same passenger information (payment card information or ID information).

Next, the main control board 150 checks whether a passenger is detected through the first passenger position detecting unit 160 ( S109 ).

Here, the first passenger position detection unit 160 includes three paired passenger detection sensors 161, 162, 163, 164, 165, 166 at a predetermined interval between the first and second gate bodies 101 and 102. They are installed in order based on the direction of passenger travel.

That is, the first passenger detection sensors 161 and 162 are installed at the entrance of the gate, and the second passenger detection sensors 163 and 164 are connected to the first passenger detection sensor 161, based on the direction of the gate entrance. 162) is installed in the following location. In addition, the third passenger detection sensors 165 and 166 are installed at a position next to the second passenger detection sensors 163 and 164 with respect to the gate entry progress direction.

Next, the main control board 150 uses the reception sensitivities (RSSI1, RSSI2) extracted from the signals received from the first and second Bluetooth modules 110 and 120 to determine the passenger's entrance to the gate, and the first The payment and gate passage processing are controlled by using the passenger detection information of the passenger location detection unit 160 .

That is, as described above, the reception sensitivities (RSSI1, RSSI2) are measured from the signals received by the first and second Bluetooth modules 110 and 120 (S108), and the passenger is detected through the first passenger position detecting unit 160. detect Here, passengers can be detected by location.

Next, by comparing the measured reception sensitivity RSSI1 of the first Bluetooth module 110 with the reception sensitivity RSSI2 of the second Bluetooth module 120, the reception sensitivity of the second Bluetooth module 120 is If it is greater than the reception sensitivity of the first Bluetooth module 110 (RSSI2 > RSSI1) (S110), it is determined that the condition is satisfied, and then, for payment and gate flap control, the It is checked whether the first passenger detection sensors 161 and 162 have detected a passenger (S111).

As a result of this check, if the passenger is not detected, it is determined that the passenger has entered the gate but has not entered the payment location and waits for payment (S113).

Contrary to this, when a passenger is detected through the first passenger detection sensors 161 and 162 of the first passenger position detection unit 160, it is determined that the passenger has entered the gate and entered the payment position, and the passenger location is determined. , and performs gate control (flap opening) (S112, S116). That is, the main control board 150 transmits a card number that requires payment processing to the payment server 300 , receives card information from the payment server 300 , and checks whether payment and pass of the card information is followed by the main control Gate control is performed by transmitting information on whether payment is completed and whether the gate has passed to the board 150 .

The first passenger position detecting unit 160 detects a passenger using the first passenger detecting sensor 161 and 162 , and then the second passenger detecting sensor 163 and 164 and the third passenger detecting sensor 165 . , 166) to continuously detect passengers.

The first to third passenger detection sensors 161 to 166 are used to accurately detect the position of the passenger inside the gate.

Next, when the passenger carries the passenger terminal and continues to pass the gate after passing the flap 103, the second passenger position detecting unit 170 installed at the inner end of the gate based on the direction of travel detects the position of the passenger ( S117).

When the second passenger position detecting unit 170 detects a passenger, the main control board 150 determines that the passenger has passed the gate, and performs gate pass processing (S118).

On the other hand, the main control board 150 compares the reception sensitivity RSSI1 of the first Bluetooth module 110 and the reception sensitivity RSSI2 of the second Bluetooth module 120 measured for the same passenger information, 2 If the reception sensitivity of the Bluetooth module 120 is less than the reception sensitivity of the first Bluetooth module 110 (RSSI2 < RSSI1), it is determined that an error has occurred in the passenger entry sequence, and the flap 103 is controlled to control the gate blocks and sends an alarm message (S114 - S115).

Through such passenger location recognition and gate control, the passenger location is accurately recognized, and the passenger's payment is processed to prevent payment errors.
