Description

Non-face-to-face simple payment service providing system {SYSTEM FOR PROVIDING NON FACE-TO-FACE BASED EASY PAYMENT SERVICE}

The present invention relates to a non-face-to-face-based simple payment service providing system, and by providing various payment options for each situation, provides a platform that can perform non-face-to-face orders and payments.

With the advent of the 4th industrial revolution, various Internet of Things (IoT) devices are being upgraded and released year after year. In particular, it can be seen that the sales information system (POS) or order management system (OMS) of stores or restaurants that are commonly encountered in daily life is gradually changing from a face-to-face order system to a non-face-to-face order system in line with the flow of the times. have. According to the type and business behavior of the food and beverage business, F&B (Food and Beverage), it is necessary to find an optimization method for how effectively it can increase revenue. You can think of ways to increase your sales. The second method is to increase net profit by reducing costs, which can be the most realistic alternative by reducing labor costs, that is, by borrowing an order management system such as a QR code on behalf of employees.

At this time, a method of ordering and paying for food non-face-to-face using a QR code has been researched and developed. In No. 2016-0060441 (released on May 30, 2016), points, stamps, and coupons can be obtained by scanning, selecting, ordering, and paying for food menus by photographing a QR code attached to a restaurant store and ordering food. And a configuration that can reduce the manpower for serving, and the payment information generated at the offline franchise of the restaurant is generated in the form of a QR code along with the transfer information such as the payee account number, and then displayed along with the bill, and the QR code is sent to the customer When scanning using a smart terminal owned and installed with an instant payment application, the customer's preset account transfer process is activated, allowing the customer to transfer the amount they want to pay to the payee account number included in the QR code. A configuration for partially paying not only the total payment amount to be paid, but also an amount corresponding to a certain amount or a certain ratio among the payment amounts is disclosed, respectively.

However, among the above configurations, in the former case, one QR code is used when scanning the QR code, so there is no way in the system to know which customer at which table is paying the bill. There is a hassle to Also, in the latter case, the QR code must be received through the bill, but since the bill is output from the POS, the process of delivering it to the customer by the employee or store owner inevitably occurs. to be. Therefore, by avoiding face-to-face contact as much as possible, research and development of a platform that can provide a payment method that can be used in various situations with various payment options while being safe even in the post-COVID-19 era of the New Normal era development is required.

In one embodiment of the present invention, the user scans the QR code placed at each seat of the table to check how many people are seated at one table and at the same time calculates the menu ordered by each individual individually with Dutch Pay, 1/N Order with various options in various situations, such as 1/N pay that is equalized, King Pay, which is a total payment made by one person, Black Knight Pay, which pays for other people's orders, and Menu Pay, which pays by selecting a specific menu and payment, and when it is confirmed that the total sum of the order amounts corresponding to the table number has been paid on the merchant terminal, the merchant simply completes the calculation process, so that the merchant separately calculates or receives a card and pays indirectly It is possible to provide a method of providing a non-face-to-face-based simple payment service that can exclude a contact situation. However, the technical task to be achieved by the present embodiment is not limited to the technical task as described above, and other technical tasks may exist.

2 is a block diagram for explaining a simple payment service providing server included in the system of FIG. 1, and FIGS. 3 and 4 are an embodiment in which a non-face-to-face-based simple payment service is implemented according to an embodiment of the present invention. It is a drawing for explaining.

Referring to FIG. 2 , the simple payment service providing server 300 may include a database conversion unit 310 , a transmission unit 320 , an ordering unit 330 , a transmission unit 340 , and a reset unit 350 . .

The simple payment service providing server 300 according to an embodiment of the present invention or another server (not shown) operating in conjunction with at least one user terminal 100, at least one affiliated store terminal 400, and at least one employee When transmitting a non-face-to-face-based simple payment service application, program, app page, web page, etc. to the terminal 500, at least one user terminal 100, at least one affiliated store terminal 400, and at least one employee terminal ( 500) may install or open a non-face-to-face-based simple payment service application, program, app page, web page, and the like. In addition, using a script executed in a web browser, the service program may be driven in at least one user terminal 100 , at least one affiliate store terminal 400 , and at least one employee terminal 500 . Here, the web browser is a program that enables the use of a web (WWW: World Wide Web) service, and refers to a program that receives and displays hypertext written in HTML (Hyper Text Mark-up Language), for example, Netscape. , Explorer, Chrome, and the like. In addition, the application means an application on the terminal, for example, includes an app (App) executed in a mobile terminal (smartphone).

Referring to FIG. 2 , the database conversion unit 310 receives the menu, table number, and number of seats from the affiliate store terminal 400 , and maps the QR code corresponding to the number of seats to the table number to obtain the unique identification code of each affiliate store. can be saved as a baseline. In the QR code, the preset link address and table information of the affiliated store are stored as default values, and the database conversion unit 310, when there is a user terminal 100 logged in to the QR code, the number of logged in user terminals 100 By increasing the seat number to correspond to , the seat number can be assigned as a variable value.

For example, if you register for 4 tables and 4 seats each at Restaurant A in Cheonho-dong, you can save it as [1234 (unique identification code) - Restaurant A - 4 tables - 16 seats]. In addition, since the QR code is for each seat, not for each table, 4 seats in Table 1 can be given seat numbers 1-1, 1-2, 1-3, 1-4, and each QR code can be created. All of these are mapped and stored based on the unique identification code, so even if you scan only the QR code, you can know which store it is, how many tables it is, and how many seats it is. The generated QR code may be produced and printed and delivered to the address of the affiliated store terminal 400 , or QR code digital data may be transmitted so that it can be printed and attached directly from the affiliated store terminal 400 .

At this time, if it is inconvenient or difficult to place the QR code for each seat, only one QR code is given to one table, but the QR code is such that the preset link address and table information of the affiliated store are stored as default values, and the database If there is a user terminal 100 logged in to the corresponding QR code, the painter 310 may increase the seat number to correspond to the number of logged in user terminals 100 and give the seat number as a variable value. For example, assuming that the link address of restaurant A is XXXX and A1 is assigned to table 1, [XXXX-A1] is stored in the QR code by default. Since the number of seats in each table can be variable as the number of people increases, when the first user terminal 100(1) logs in to the QR code called [XXXX-A1], the database conversion unit 310 generates [XXXX-A1-C1] As a result, C1 (Chair 1) is set as a variable value and added. If only one person is seated, the variable value will end at C1, but if three people are seated, the variable value will increase to C1, C2, and C3.

When the QR code is scanned by the at least one user terminal 100 , the transmitter 320 extracts the unique identification code of the affiliated store previously mapped to the QR code and transmits the menu to the at least one user terminal 100 . have. The QR code arranged for each seat may be a code including a unique identification code of the affiliated store terminal 400, a table number, and a seat number.

The ordering unit 330 may transmit an order form to the affiliate store terminal 400 of the affiliate store previously mapped to the QR code when the order event is output after selecting at least one menu in the at least one user terminal 100 . In an embodiment of the present invention, an unmanned serving robot may be further used to realize complete non-face-to-face. Indoor mobile robots need to be aware of indoor positioning and the surrounding environment, and there are various technologies for indoor positioning. In order to use this positioning technology, positioning sensors for StarGazer robots can be used as a ceiling landmark, and positioning can be carried out by triangulation using indoor GPS, WiFi, or beacons. Simultaneous Localization And Mapping (SLAM), which is the most essential for indoor mobile robots, is a technology that surveys a map while simultaneously positioning.

To this end, it is possible to create a map for autonomous driving through positioning and a LiDAR (Light Detection And Ranging) sensor that emits laser pulses and measures the distance to nearby obstacles with the return time. In order to overcome the uncertainty of positioning, a signal processing method such as a Kalman filter or a Montecarlo positioning using a particle filter may be used. The mapping algorithm may use a particle filtered Grid Map (PGM) corrected by a particle filter, or an Occupancy Grid Map (OGM). Djikstra's shortest distance Visibility Graph, A* algorithm, D* algorithm, RRT (Rapidly-exploring Random Trees), DWA (Dynamic Window Approach) ), may be implemented according to various algorithms such as Potential Field.

A development environment provided for robot development may use, for example, a Robot Operating System (ROS). In this case, program packages for detecting and driving various sensors constituting the robot are provided. Collaboration between multiple robots is also possible by allowing multiple processes to be managed and interlinked for complex robot movements. Posture control can also be facilitated by providing real-time coordinate transformation data between multiple coordinate frames using the TF library. For example, using a Kobuki mobile body of the Turtlebot 2 series and using Nvidia's Jetson TX2 board as the main control computer, install the ROS Kinetic Kame version of the meta operating system on the Linux Ubuntu 16.04 version operating system. It is possible to implement a serving mobile robot that moves to the corresponding destination.

For this, a map is created by detecting the distance to surrounding obstacles with positioning and LiDAR sensors while moving the robot using the SLAM mapping program package supported by ROS. Based on this map, using the autonomous driving program package supported by ROS, set the route from the origin to the destination, and control the rotational speed of the two old-wheeled motors of the Kobuki moving body to adjust the translational speed and the rotational angular speed to the destination. will move To set the route, first touch the TFT-LCD touch screen connected to the Jetson TX2 board, which is the main control computer, and say the destination location to the microphone, for example, “Table No. 1”. It creates a voice file and sends this voice file to the Electronic and Telecommunications Research Institute (ETRI) Open AI Server, and then receives the recognized text data. By identifying the table number in the front part of the “table” in the text data, the location on the map that matches the table number is sent to the autonomous driving process as a topic message to set the destination route.

<ROS>

ROS (Robot Operating System) is installed in various operating systems for convenient robot development, management and operation, and TCI-IP is installed between the processes of different types of computers connected to the Internet, such as virtualization of hardware, low-level device control, and the Internet. It provides application packages necessary for the distributed computing environment through message communication and operation control of various hardware modules constituting the robot. In addition, utilities such as Gazebo, a 3D simulator, Rviz, a visualization tool, and RQT, a GUI tool set may be required.

ROS provides distributed processing environments such as Topic, Service, and Action Service. Two nodes composed of a Publisher and a Subscriber through a topic message are the most used. It interworks by allowing TCP-IP socket communication between processes. For example, node A, which is a remote key node process, is a publisher node that wants to control movement through the arrow keys on the keyboard, whereas node B is a subscriber node that receives this direction key control signal and causes objects in the window to move. For this, the nodes that want to interwork send their IP and port, topic message name and message type information to the master node process. When the master node passes the IP and port information of the counterpart node to which it wants to communicate to nodes requesting the same topic message, it enables socket communication between them.

Each computer composing the robot configures the IP and port information of the computer that becomes the master node in the .bashrc shell script file. Now, on the computer that becomes the master node, open a terminal and use the “roscore” ROS shell command to start the master node process. To run the two interlocking node processes, open a terminal and run it through the “rosrun” ROS shell command. In particular, the RQT utility shows the interworking between all node processes occurring in the current robot by displaying the node name and topic message name in the form of a graph.

In this way, many packages for node processes that are interlocked for robot operation in ROS environment are provided in ROS-related git-hub, so you can easily copy and compile them or install them using the apt-get installation shell command of linux. Packages for robot operation are provided as ROS applications for driving a specific manufacturer's specific model hardware module used in the robot, creating maps by SLAM, and controlling the robot such as autonomous driving. It can be implemented by selecting suitable packages according to the ROS version, the specifications of the robot to be driven, and the specifications of the hardware module.

<Map Creation & Autonomous Driving>

While moving first, the mobile robot uses distance sensors such as LiDAR or depth camera to detect nearby obstacles and creates a map through the positioning process. Then, based on this map, you need to set a route to the desired destination and allow it to drive autonomously. First, in the positioning process, the robot can be expressed as (xk, yk, θk) as the position in the two-dimensional xy at the point k and the direction angle at the position. At this time, the rotation angular velocity w ^l k and w ^r k of the left and right wheels detected through the encoder rotation speed sensor of the robot's left and right wheels, the radius r of the wheel, and the robot translation speed vk at the point k from the distance D between the wheels and the robot The rotational angular velocity wk can be obtained as shown in Equations 1 and 2 below, respectively.

From vk and wk, the movement distance Δsk and the direction rotation angle Δθk at the time k+1 after Δt time can be obtained, and from this, the position and the direction angle at the time k+1 (xk+1, yk+1, Positioning can be performed by obtaining θk+1) as in Equation (3).

However, even if the rotation speed sensor error or rotation speed detection is correctly detected, the actual distance traveled may vary due to wheel slippage or friction, and even a very small error will inevitably increase the positioning error accumulated while driving. In this sense, it is necessary to measure and correct probabilistic statistics for positioning errors in every section, and as mentioned above, it can be corrected using a statistical algorithm such as a Kalman filter. Mobile robots will be able to perform better positioning correction from distance detection to surrounding obstacles through distance sensors such as LiDAR and create more accurate maps.

Now, if the destination coordinates are determined with the robot equipped with a map, the movement path from the origin to the destination is calculated according to the route setting calculation algorithm, and the old-wheeled motor is driven to enable autonomous driving. According to the set route, the movement distance Δsk and the directional rotation angle Δθk from the k time point to the next k+1 time point are given for each △t time, and the rotation speed of the motor is obtained from this. PWM (Pulse Width Modulation) is applied to the left and right wheel motors. Even during autonomous driving, various sensors such as encoders, IMUs (Inertia Measurement Unit), and depth cameras are constantly used to check deviations from the set route while measuring, and it can be set to follow the calibrated route.

The transmitting unit 340 may transmit a result event to the affiliated store terminal 400 when payment is performed in at least one user terminal 100 . The affiliated store terminal 400 outputs an order book including at least one menu received from at least one user terminal 100 , and receives and outputs an event as a result of payment performed by at least one user terminal 100 . can At this time, the at least one user terminal 100 scans the QR code arranged for each seat, selects at least one menu, transmits an order event, and performs payment based on at least one type of option. have.

<King Fay>

The at least one type of option may include a King Pay for performing a total amount payment corresponding to the total sum of order events that are generated by being mapped to a table number. In this case, King Pay is an option for one person per table number to calculate the total amount of the order table. When one member (user) selects this option, payment must be made within 3 minutes, and the option option is inactive for other members until then. At this time, if the king pay is not executed within 3 minutes, the options may be reset. Of course, it is not limited to 3 minutes, and various times may be set according to embodiments.

<Emperor Fay>

At least one type of option is not only King Pay, which performs a full payment corresponding to the total sum of order events mapped to table numbers, but also other table numbers that are mapped to other table numbers and stored It is an option to pay all order details. If King Pay was an option to calculate the total amount of the order table by one person per table number, Emperor Pay is an option to calculate the total amount of the order table by one person, not only the current table number but also other table numbers. For example, you will need it if you have to pay for all the other tables at a group dinner or a booking bar. When Emperor Pay is selected, all table numbers with outstanding order history in the affiliated store are displayed, and the user who selected Emperor Pay can selectively select a table number or select all tables. In this case, King It may be a method in which the payment is added to the pay. In this case, the emperor pay may be an option corresponding to the sub-menu of the king pay, but it may not.

<Dutch Pay>

The at least one type of option may include a Dutch Pay for performing a payment for an amount corresponding to an order event that is generated by being mapped to a table number and a QR code. In this case, Dutch pay means that each user calculates the menu ordered by each user, and is different from equal payment such as 1/N. Since the menus selected together with each nickname are separated in the order table, when the Dutch pay option is selected, it is possible to calculate only the amount of the menu ordered by the user on the screen of each user terminal 100 .

When the option of Dutch Pay is selected in one user terminal 100, the payment amount corresponding to the menu ordered is also displayed in the respective payment windows in other user terminals 100 that have scanned the QR code from the table number. At this time, all options are active, and when one of the members pays with Dutch Pay, other pay options are inactive, and only Black Knight Pay is activated, so the member who selects the Black Knight Pay option sees and selects the list of members who have not yet paid If you do, you will be able to pay for the Black Knight because it will be added to your payment window.

<1/N Pay>

At least one kind of option includes a 1/N pay that performs a payment for the total amount corresponding to the total sum of order events mapped to the table number divided by the number of QR codes scanned from the table number can do. It is a method of paying in equal proportion to the number of participants, and in cases where it is difficult to separately calculate what each person ate, such as a party, it is usually a method to divide the total amount equally by the number of participants. Instead, you can finish all the calculations at the table in the store and leave.

When the 1/N pay option is selected in one user terminal 100, the total of all menus ordered from the table number is also added to the other user terminal 100 that has scanned the QR code from the corresponding table number to the person who scanned the QR code Divided by the number of , the equal payment amount is displayed on each payment window. At this time, all options are active, and if one of the members pays with 1/N pay, other pay options are inactive, and only Black Knight Pay is activated, so the member who selects the Black Knight Pay option will see the list of members who have not yet paid. If you view and select, you can pay for the Black Knight because it is added to your payment window and appears.

<Menu Pay>

The at least one type of option may include a menu pay for performing payment for an amount corresponding to an order event selected by at least one user terminal 100 among order events mapped to table numbers and generated. It is an option to pay for a specific menu. For example, if one of your coworkers having lunch together says that you will pay for sweet and sour pork, you can pay for a specific menu, that is, sweet and sour pork through the menu pay option. It can be used when you want to buy a special menu such as alcohol or snacks at a dinner party. In addition, members who did not log in at first can participate by selecting the pay option before payment. Alternatively, when a link is sent to a user who does not have an application according to an embodiment of the present invention, the payment can be made by moving to another simple payment platform without installing the application, or payment can be made directly from the link based on a web page.

<Black Knight Fay>

The at least one type of option may include a black knight pay for performing payment for an amount corresponding to an order event selected by at least one user terminal 100 from among order events mapped to table numbers and generated instead. The Black Knight Pay option is a function to make payments on behalf of those who cannot make payments. Generally, there is only a single payment for the amount collected in the order table, and there is only a Dutch Pay-type prepayment that allows simultaneous payment at the cafe and ordering. In an embodiment of the present invention, when payment is not made by infants, minors who have parental rights to payment, or IT vulnerable classes who do not know about simple payment, payment can be performed using the Black Knight Pay option instead. A black knight at a drinking party refers to a person who drinks on behalf of a person who is in a difficult situation where he or she cannot drink alcohol.

The reset unit 350, when the total sum of payment amounts included in the result event transmitted from the delivery unit 340 is the same as the total amount corresponding to the total sum of the order events generated by mapping the table number to the affiliated store terminal 400 ), when a confirmation event is generated in the affiliated store terminal 400, an exit event is generated in at least one user terminal 100 to terminate and initialize the order process corresponding to the table number.

At this time, an IoT-based system can be designed to move chairs to each table when an exit event occurs. For example, a motor can be controlled using a motor driver, and the distance and direction between a chair and a table can be found using Zigbee to control the chair to move to the table position. The ultrasonic sensor recognizes obstacles so that the chair can avoid obstacles, and the infrared sensor recognizes the distance between the chair and the table so that the store owner or staff can know whether the chair is in order. One-to-one communication may be performed between the affiliated store terminal 400 and the chair using the Bluetooth module, and the affiliated store terminal 400 may output on which table the chairs are arranged or not.

The affiliated store terminal 400 may visualize and output the movement of the chair to a position to be arranged based on the signal strength through the Zigbee through a touch screen operation. When the chair encounters an obstacle during movement, it is detected by an ultrasonic sensor to avoid it, and when it arrives at the target table, the operation can be completed.

On the other hand, at least one employee terminal 500 is interworking with each other within the wireless network connected to the affiliated store terminal 400, and forms a channel with at least one user terminal 100 or affiliated store terminal 400 to form a voice or message can send and receive In addition, when the "employee" button is pressed in the user terminal 100, a function for making a call with the employee terminal 500 like a radio may be further included. For example, if a non-face-to-face order results in slow response, no response to calls, or an open-air restaurant that is too far away, the ability to have a simple conversation with an employee may be added. However, there is no call tone, it can be connected directly like a radio, and it can be operated in a way that combines a radio and a call in a form that allows two-way calls rather than a one-way conversation like a radio.

At this time, the connection is possible not only between the user terminal 100 and the employee terminal 500, but also between the employee terminal 400, and between the affiliated store terminal 400 or the manager terminal (not shown) and the employee terminal 500 is also possible. .
