Abstract

In a system that processes bus boarding and payment using a tagless payment app, a tagless boarding processing device and method using a magnetic field that allows stable determination of boarding using the strength of the magnetic force according to the opening and closing of the door As a result, when the tagless payment app is activated and the magnetic field generated by the bus is detected using a magnetic sensor, the magnetic field is detected, the magnetic field strength is compared with the preset reference magnetic strength strength for boarding discrimination, and the detected magnetic field is detected using a magnetic sensor. If the magnetic force strength exceeds the standard magnetic force strength, it is judged as the first ride. After being judged as the first ride, if a beacon signal sent from the boarding beacon in the bus is received, it is judged as the final ride. If it is judged as the final ride, payment is made.

Description

Tagless boarding handling device and method using magnetic field}

The present invention relates to a tagless boarding processing device and method using a magnetic field. In particular, in a system that processes bus boarding and payment using a tagless payment app, the strength of the magnetic force according to the opening and closing of the door is used to stably determine whether or not to ride. It relates to a tagless riding processing device and method using a magnetic field that enables judgment.

Recently, as communication infrastructure has expanded and the electronic communication industry has developed, active research is being conducted on various payment systems and methods using smartphones.

In particular, in public transportation, payment is made for each passenger boarding/disembarkation, so when payment is made in cash, not only is payment inconvenient, but the waiting time for passengers is delayed.

Accordingly, in recent years, NFC (Near Field Communication) chips have been installed in smartphones, transportation cards, and credit cards, and payment methods using NFC have been widely used.

At this time, NFC is one of the radio tag (RFID) technologies, and is a non-contact communication technology using a frequency band of 13.56 MHz. It has the advantage of excellent security and low price due to a short communication distance.

However, since the communication distance of the NFC payment method is less than 10cm, the user must directly move the NFC card or NFC terminal to a location close to the payment terminal to make a payment, which has the disadvantage of not only making payment cumbersome but also requiring waiting time.

Additionally, the NFC payment method has the problem that if disembarkation tagging is accidentally omitted, it is treated as the longest ride, causing unnecessary cost consumption for the user.

Here, bus passenger fares are made through linkage between the driver terminal (vehicle terminal) and the payment server. To this end, the driver terminal obtains and stores boarding and disembarking information, and transmits and receives payment information to the payment server. In addition to the management of boarding and disembarking passengers and payment processing, the driver terminal not only provides data communication with various devices such as stop guidance, communication with the Bus Information System (BIS), communication with the stop system installed at the stop, and data communication with the control server, but also a large amount of data. Various functions such as acquisition and storage are required. Accordingly, modern driver terminals have complex system configurations due to the addition of various functions, and complex operation due to the installation of various algorithms, which ultimately causes an increase in the cost of the driver terminals.

Therefore, the inconvenience of direct tagging is resolved by allowing payment of bus fares to be made through a non-contact communication method, and the configuration and operation of the driver terminal is simplified by having the passenger terminal perform the boarding and alighting payment processing performed on the driver terminal instead. There is a demand for non-contact ride fare payment technology that can reduce the cost of driver terminals.

Meanwhile, technologies previously proposed for paying fares for public transportation such as buses through non-contact are disclosed in <Patent Document 1> to <Patent Document 4> below.

The prior art disclosed in <Patent Document 1> allows public transportation payment approval to be made through the terminal identification information of the user using public transportation and the authentication key of the beacon installed in the corresponding transportation method, thereby providing a transportation card to a conventional public transportation terminal. We provide a public transportation payment method and system using beacons that allows you to use transportation without making personal contact.

In addition, the prior art disclosed in <Patent Document 2> installs a two-way beacon near the entrance door of the bus, installs a plurality of receiving beacons inside the bus, and then tracks the user's location through beacon communication with the user terminal. When it is determined that the user has boarded the vehicle, fare payment is automatically processed.

In addition, <Patent Document 3> provides technology to individually and quickly process payments for multiple users using beacons, such as in public transportation payment systems such as buses and subways.

In addition, <Patent Document 4> provides an automatic bus fare payment system and method that determines the location of the user terminal using a beacon sensor and automatically pays the bus fare.

This conventional technology uses a beacon to determine whether to ride, but since beacons are Bluetooth (BLE)-based communication, errors in signal strength occur depending on surrounding environmental factors, causing errors in determining whether to ride. There is.

In particular, the signal strength of the beacon varies depending on the type and holding posture of the smartphone, making it difficult to reliably determine whether or not to ride.

Republic of Korea registered patent 10-1647834 (registered on 2016.08.05) (Public transportation payment method and system using beacons) Republic of Korea registered patent 10-1754747 (registered on June 30, 2017) (vehicle fare payment system and method using beacons) Republic of Korea registered patent 10-1862384 (registered on May 23, 2018) (Beacon-based rapid payment system using beacon coverage multiplexing) Republic of Korea registered patent 10-2051618 (registered on November 27, 2019) (automatic bus fare payment system and method)

Therefore, the present invention was proposed to improve the inconveniences arising from the conventional tagging-based public transportation fare payment method as described above and the problem of unstable riding presence or absence judgment caused by the beacon signal strength varying depending on the environment when paying fares by contactless method. In a system that processes bus boarding and payment using a tagless payment app, we provide a tagless boarding processing device and method using a magnetic field that can stably determine whether or not to board by using the strength of the magnetic force according to the opening and closing of the door. The purpose is to do this.

Hereinafter, a tagless riding processing device and method using a magnetic field according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

The terms or words used in the present invention described below should not be construed as limited to their usual or dictionary meanings, and the inventor may appropriately define the concept of the term in order to explain his/her invention in the best way. It must be interpreted with meaning and concept consistent with the technical idea of the present invention based on the principle that it can be done.

Therefore, the embodiments described in this specification and the configurations shown in the drawings are only preferred embodiments of the present invention and do not represent the entire technical idea of the present invention, and therefore various equivalents and It should be understood that variations may exist.

Figure 1 is an example of the installation of a magnet and an electromagnet in a tagless ride processing device using a magnetic field according to the present invention, Figure 2 is a state diagram of the position of the magnet and electromagnet according to the opening and closing of the door in the present invention, and Figures 3a and 3b are a diagram showing the position of the magnet and electromagnet according to the opening and closing of the door in the present invention. This is an explanatory diagram to explain the strength of magnetic force.

The present invention installs a magnet (11) for forming a magnetic field on the door (10) of the bus (1), and supplies power to the support (21) installed on the railing of the door (10) of the bus (1). An electromagnet 20 that forms a magnetic field is installed.

With the magnet 11 and the electromagnet 20 installed in this way, as shown in FIG. 2, when the door 10 is closed, the magnet 11 and the electromagnet 20 are in a perpendicular state, and the When the door 10 is opened, the magnet 11 and the electromagnet 20 face each other directly.

When the door 10 is closed, as shown in FIG. 3A, a magnetic field is formed in a specific direction only by the magnet 11, and the strength of the magnetic field formed, that is, the strength of the magnetic force, is also very weak.

On the other hand, when the door 10 is open, as shown in FIG. 3b, the electromagnet 20 is driven, and a magnetic field is formed simultaneously by the driving electromagnet 20 and the magnet 11, so that the strength of the magnetic field, that is, , the magnetic force becomes very strong.

Here, part of the magnet 11 prevents magnetic fields from being generated in all directions except for one direction by the first shielding member 31, and part of the electromagnet 20 is prevented by the second shielding member 32. Except for one direction, it prevents magnetic fields from being generated in all other directions.

The first shielding member 31 serves to ensure that the magnetic field formed in the magnet 11 is formed only in a specific direction and to shield magnetic fields in other directions, and the first shielding member 32 serves to block the electromagnet 20. It serves to ensure that the magnetic field formed only in a specific direction is formed and to shield magnetic fields in other directions.

These first and second shielding members 31 and 32 are formed in a “ㄷ”-shaped plate shape and are implemented in a form that surrounds the magnet 11 and the electromagnet 20, respectively, so that the magnet 11 and the electromagnet 20 The direction of magnetic field formation can be adjusted. Here, the first and second shielding members 31 and 32 are preferably made of permalloy or metal material with excellent magnetic field shielding ability to achieve high shielding performance.

Figures 4 and 5 are configuration diagrams of a “tagless ride processing device using a magnetic field” according to the present invention.

First, Figure 4 shows a device implemented in a bus 1, which is a vehicle, and includes a door opening/closing detection unit 40 that detects the opening/closing of the door 10 of the bus 1, and the door opening/closing detection unit 40. It may include an electromagnet driver 50 that drives the electromagnet 20 when opening is detected and turns off the electromagnet 20 when the door 10 is closed.

Although this vehicle device is not shown in the drawing, it is assumed that a plurality of boarding beacons that transmit vehicle information are provided at a predetermined location inside the bus 1.

Figure 5 shows a device implemented in the passenger terminal 100.

The passenger terminal 100 detects the magnetic field formed by the magnet 11 and the electromagnet 20, makes the primary boarding determination based on the magnetic force strength, and uses a boarding beacon for transmitting vehicle information mounted on the bus 1. When a signal is received, it is determined to be the final ride and transmits card information for payment.

As shown in FIG. 5, this passenger terminal 100 includes a tagless payment app executing unit 101 that executes a tagless payment app for processing bus fare payment using a tagless payment method, and the magnet 11. and a magnetic sensor 102 that detects the magnetic field formed by the electromagnet 20, a riding beacon receiver 103 that receives a beacon signal transmitted from a riding beacon in the bus 1, and detection by the magnetic sensor 102. A ride determination unit 104 that determines the ride based on the magnetic strength of one magnetic field and the beacon signal received from the ride beacon receiver 103. When the ride is determined in the ride determination unit 104, the ride is switched to payment mode and the card is used. It may include a Bluetooth module 105 that transmits information.

This riding determination unit 104 primarily determines riding when the magnetic strength of the magnetic field detected by the magnetic sensor 102 is greater than the standard magnetic strength preset for determining riding, and after determining the primary riding, the riding is performed. When the beacon signal sent from the beacon is received, it can be finally determined that it is a ride.

The operation of the tagless ride processing device using a magnetic field according to the present invention configured as described above will be described in detail as follows.

First, a passenger who wants to board the bus 1 runs the tagless payment app provided on the passenger terminal 100. When a request is made to run the tagless payment app, the tagless payment app executing unit 101 executes the tagless payment app.

Next, when the door 10 of the bus 1 is opened, people get on the inside of the bus 1.

Here, when the door 10 of the bus 1 is opened, the door opening/closing detection unit 40 detects this and transmits door 10 opening information to the electromagnet driver 50.

The electromagnet driver 50 that receives the door 10 opening information drives the electromagnet 20. That is, the electromagnet 20 is turned on.

An electromagnet is a magnet that is magnetized when a current flows and acts as a magnet, and returns to its original state when the current is cut off.

When the open door 20 is closed, the electromagnet 20 is turned off.

A passenger 1 carries a passenger terminal 100 and enters the inside of the bus 1 through the open door 10.

At this time, the passenger terminal 100 detects a magnetic field through the magnetic sensor 102, and when the magnetic field is detected, it transmits it as a magnetic force intensity value to the ride determination unit 104.

The ride determination unit 104 determines whether or not there is a primary ride based on the magnetic force strength.

That is, when the magnetic force intensity value is input, the riding determination unit 104 compares the detected magnetic force intensity with a preset reference magnetic force intensity for determining riding, and if the detected magnetic force intensity is greater than the reference magnetic force intensity, the first riding judged to be

Here, as shown in FIG. 3A, the magnetic force intensity detected by the magnetic sensor 102 when the door 10 is closed is 60 μT or less, and the magnetic force detected by the magnetic sensor 102 when the door 10 is open is 60 μT or less. The magnetic force strength is over 100μT. Therefore, if you set the standard magnetic force strength to 90μT, you can accurately determine whether or not you are riding.

If the magnetic force intensity detected through the above magnetic force intensity comparison process is greater than or equal to the reference magnetic force intensity, the riding determination unit 104 primarily determines it as a riding, and then again transmits the riding beacon signal through the riding beacon receiver 103. Check whether the signal is being received.

Here, a plurality of boarding beacons that transmit vehicle information are installed inside the bus 1, and vehicle information is continuously transmitted through the beacons.

When the passenger terminal 100 enters the vehicle, the boarding beacon receiver 103 receives a beacon signal transmitted from the boarding beacon. Here, a plurality of boarding beacons are installed at different locations, and the passenger terminal 100 receives the boarding beacon signals using a Bluetooth module.

If the number of boarding beacon signals received is at least two, the boarding determination unit 104 finally determines that the passenger has boarded the bus.

When it is determined that a passenger is on board, the tagless payment app switches to payment mode and transmits card information through the Bluetooth module 105.

When the driver terminal installed on the bus receives card information for payment of the fare, it determines that the ride is normal and processes the payment in conjunction with the payment server.

In this way, the present invention accurately and stably detects riding by using magnetic strength and riding beacon signals in combination.

Figure 6 is a flow chart showing the "tagless riding processing method using a magnetic field" according to the present invention, (a) activating the tagless payment app (S101), (b) magnetic field generated in the bus 1 In the step (S102) of detecting using the sensor 102, (c) when a magnetic field is detected in step (b), the detected magnetic field is compared with the reference magnetic force intensity preset for determining riding, and the detection Step (S103 - S104) of determining primary boarding when the magnetic force strength is greater than or equal to the reference magnetic strength; (d) After determining primary boarding, receiving a beacon signal transmitted from the boarding beacon in the bus 1 If so, it may include steps of determining that it is the final ride (S105 - S106), and (e) if it is determined that it is the final ride, switching to payment mode and sending card information (S107 - S108).

The operation of the tagless riding processing method using a magnetic field according to the present invention configured as described above will be described in detail as follows.

First, a passenger who wants to board the bus 1 runs the tagless payment app provided on the passenger terminal 100 (S101). When a request is made to run the tagless payment app, the tagless payment app executing unit 101 executes the tagless payment app.

Next, when the door 10 of the bus 1 is opened, people get on the inside of the bus 1.

Here, when the door 10 of the bus 1 is opened, the door opening/closing detection unit 40 detects this and transmits door 10 opening information to the electromagnet driver 50.

The electromagnet driver 50 that receives the door 10 opening information drives the electromagnet 20. That is, the electromagnet 20 is turned on.

An electromagnet is a magnet that is magnetized when a current flows and acts as a magnet, and returns to its original state when the current is cut off. When the open door 20 is closed, the electromagnet 20 is turned off.

A passenger 1 carries a passenger terminal 100 and enters the inside of the bus 1 through the open door 10.

At this time, the passenger terminal 100 detects a magnetic field through the magnetic sensor 102, and when the magnetic field is detected, it transmits it as a magnetic force intensity value to the ride determination unit 104 (S102).

The ride determination unit 104 determines whether or not there is a primary ride based on the magnetic force strength.

That is, when the magnetic force intensity value is input, the riding determination unit 104 compares the detected magnetic force intensity with a preset reference magnetic force intensity for determining riding, and if the detected magnetic force intensity is greater than the reference magnetic force intensity, the first riding It is determined that it is (S103).

Here, as shown in FIG. 3A, the magnetic force intensity detected by the magnetic sensor 102 when the door 10 is closed is 60 μT or less, and the magnetic force detected by the magnetic sensor 102 when the door 10 is open is 60 μT or less. The magnetic force strength is over 100μT. Therefore, if you set the standard magnetic force strength to 90μT, you can accurately determine whether or not you are riding.

If the magnetic force intensity detected through the above magnetic force intensity comparison process is greater than or equal to the reference magnetic force intensity, the riding determination unit 104 first determines the ride as a ride (S104) and then again through the riding beacon receiver 103. Check whether the signal from the boarding beacon is received (S105).

Here, a plurality of boarding beacons that transmit vehicle information are installed inside the bus 1, and vehicle information is continuously transmitted through the beacons.

When the passenger terminal 100 enters the vehicle, the boarding beacon receiver 103 receives a beacon signal transmitted from the boarding beacon. Here, a plurality of boarding beacons are installed at different locations, and the passenger terminal 100 receives the boarding beacon signals using a Bluetooth module.

Next, the boarding determination unit 104 finally determines that the passenger has boarded the bus if the number of received boarding beacon signals is at least two (S105). Here, the reason it is judged as boarding when at least 2 boarding beacon signals are received is because passengers board the bus but get on the bus by mistake and get off again. Taking this situation into consideration, the final number of boarding is 2 or more. When the beacon signal is received, it is determined that the final boarding has occurred.

When it is determined that a passenger is on board, the tagless payment app switches to payment mode and transmits card information through the Bluetooth module 105 (S107 - S108).

When the driver terminal installed on the bus receives card information for payment of the fare, it determines that the ride is normal and processes the payment in conjunction with the payment server.

According to the present invention described above, it is possible to reliably determine whether to board the bus by using the strength of the magnetic force according to the opening and closing of the door, and through this, payment errors can be prevented in the tagless bus payment system.

Although the invention made by the present inventor has been described in detail according to the above embodiments, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the invention, as is known in the art. It is self-evident to those who have.
