1 is an exemplary view showing a schematic configuration of a reference banknote information localization system according to a first embodiment of the present invention.

As shown in FIG. 1 , the reference banknote information localization system includes a banknote sorter 100 and a server 300 .

The bill sorting machine 100 performs a function of not only counting bills but also discriminating whether the accepted bills are legitimate or suitable for circulation, similar to a normal bill sorting machine.

The bill sorting machine 100 localizes the localization criteria of local banknotes to cover all the characteristics of various types of actual bills circulating locally through localization (that is, localization of data or software related to bill discrimination). It performs the function of obtaining (or collecting) the bill information required for localization work, that is, the reference bill information for bill discrimination.

The bill sorting machine 100 can easily acquire (or collect) reference bill information (ie, bill discrimination information) in an interactive manner so that even general users other than professional workers (ie, A/S workers) can use it. (Hereinafter referred to as a Tutor interface function in this embodiment) is provided. Here, the tutor interface function is a function of guiding (or instructing) a task (or action) to be performed to obtain valid reference banknote information for general users.

The bill sorting machine 100 may access the server 300 through a wired or wireless communication method. To this end, the bill sorting machine 100 includes a wired or wireless communication module (not shown).

However, when the bill sorting machine 100 does not include a wired or wireless communication module (not shown), as shown in FIG. 2, the information processing device 200 (eg, a smart terminal, a portable computer (notebook PC, It is possible to access the server 300 in a wired or wireless communication method through a device having communication and data processing functions, such as a stick PC, a mobile terminal, a personal portable terminal, etc., and the information processing device 200 is connected. To this end, the bill sorting machine 100 may further include an I/O interface unit (not shown) (eg, a USB port, an HDMI port, a serial port, a parallel port, an infrared module, an NFC module, a Bluetooth module, etc.).

In this case, the wireless communication method may include a short-distance wireless communication method including Wi-Fi or a long-distance wireless communication method including mobile communication (eg, 3G, 4G, LTE, etc.).

Each of the bill sorting machines 100 is set with a unique ID (or unique authentication information such as MAC address or S/N number, which is distinguished from other bill sorting machines). The ID may include information for distinguishing an installation place, region, or country.

The bill sorting machine 100 acquires (or collects) reference bill information necessary for localization and transmits it to the server 300 . At this time, the bill sorting machine 100 directly transmits reference bill information to the server 300 through a built-in wired or wireless communication module (not shown), or transfers reference bill information to the server 300 through the information processing device 200. It can be transmitted to the server 300, the reference banknote information can be compressed and transmitted in consideration of transmission efficiency, or encrypted for security.

The server 300 collects reference bill information transmitted from the bill sorting machine 100 or the information processing device 200 .

At this time, the collected reference banknote information may be classified and collected by type. For example, the reference banknote information may be classified and collected by region, country, installation location, period, machine ID, banknote type, and bill type.

The server 300 extracts unique banknote characteristic information (ie, sensor data obtained from various sensors) for each banknote type in a corresponding region or country from the collected reference banknote information. The sensor data (characteristic information of banknotes) is an optical sensor (Complementary metal? oxide? semiconductor (CMOS) type image sensor, CCD (Charge-Coupled Device) type image sensor, CIS (Contact Image sensor), infrared (IR) sensor, ultraviolet (UV) sensor, etc.), sound wave sensor, magnetic sensor (MG), eddy current sensor, displacement sensor, etc. Data sensed by various sensors mounted in the banknote sorting machine 100 to extract characteristic information of banknotes to be.

At this time, in extracting the unique banknote characteristic information (ie, sensor data) for each denomination, the method for extracting the characteristic information is not limited. Network feature extraction method, 4-way component feature extraction method, histogram feature extraction method, 8-way chaincode feature extraction method, gradient feature extraction method using Sobel operator, SVM (Support Vector Machine), neural network genetic algorithm, machine learning (machine learning) ) program can be used.

The server 300 checks (verifies) whether the extracted banknote characteristic information unique to each denomination has discriminative power against the banknote characteristic information of other denominations in the corresponding region or country, and also checks (verifies) whether the banknotes by denomination of different regions or countries in the world. It also checks (verifies) whether there is discriminative power for characteristic information.

Hereinafter, the discrimination power check (verification) will be described in more detail.

The discrimination power verification is primarily filtering in a banknote sorting machine.

In the banknote straightening machine, first, the skew angle of the introduced banknote (ie, the angle at which the banknote is not correctly input but twisted) is measured from image information acquired for the introduced banknote to verify whether or not the banknote is valid, thereby determining the valid range. In case of excess, guide to reintroduce.

Second, by using a thickness sensor such as a sound wave sensor or a displacement sensor, it is verified whether the inserted bills are doubled (when the sensing data exceeds a threshold value), and if the bills are in the overlapped state, guidance is given to reintroduce them.

Thirdly, whether or not the inserted banknotes are the same denomination banknotes on the same side is checked using one of the methods below, and guidance is given to re-insert if they are not the same denomination banknotes on the same side.

For example, methods for confirming whether or not the banknotes of the same denomination on the same side are 'frequency similarity analysis (high frequency area, low frequency area)', 'similarity analysis of similarity map', 'image similarity analysis (visible light according to wavelength, IR data comparison)', and 'other characteristic similarity analysis (size, color, brightness, etc.)'.

Next, after filtering in the banknote sorting machine as described above, the discrimination power is secondarily verified in the server.

The server first re-verifies the validity of the acquired data (banknote characteristic information) transmitted from the banknote sorting machine (eg, 1,000 won note, side A/side B, etc.).

Subsequently, the type of ticket of the corresponding country is recognized using algorithms such as PCA (Principal Component Analysis), SVM (Support Vector Machine), NNP (Nearest Neighbor Point), and the like.

For example, in the PCA method, a. Set the standard for the misrecognition rate between ticket types or the recognition rate within a ticket type by properly adjusting the threshold for classification (recognition) of sovereign rights, and b. Divide the entire image area of the type of voucher whose validity has been verified into certain areas, and sequentially calculate each area to separate discriminatory elements. Update the separated discriminating factor. In addition, for example, in the NNP method, the 'B' method is resized and patterned to match pattern data for each country to recognize the type of ticket of the country, and the type of ticket of the country completed in this way is previously stored It is verified again by matching with the national DB (finally determined using the dimension and similarity measurement method of SVM).

In order to increase the precision of the method, the processing method may be a parallel processing method using a plurality of processors or a distributed processing method of a clouding method, and a non-distributed (eg, single processor) processing method In this case, in consideration of computational efficiency (to effectively reduce the number of operations), only areas containing discriminatory elements may be specified based on existing data, and discriminatory elements may be separated within a specific area.

The discrimination power check (verification) for the banknote characteristic information unique to each denomination may be repeatedly performed at least several times.

The banknote characteristic information for which the discrimination power has been checked (verified) is determined as the unique banknote characteristic information of the corresponding denomination.

The server 300 localizes a program of a banknote sorting machine in a corresponding region or country, ie, a program and data for banknote discrimination, by reflecting the determined unique characteristic information (ie, sensor data) of the corresponding denomination. The server 300 localizes the localized banknote discrimination program (ie, a program for banknote discrimination) and data in various ways. For example, when a banknote sorting machine is in a networking state, localization is performed automatically or manually by accessing the server, and when it is not in a networking state, an information processing device capable of communication and networking accesses the server to perform localization. It receives the discrimination program and data and performs localization by connecting to the I/O port included in the paper money sorting machine. In other words, it is localized by sending it to the banknote sorting machine of the region or country.

When the localization work is completed, other bill sorting machines installed in the corresponding region or country can be quickly localized accordingly, so that they can be operated in an optimized state.

In addition, at this time, the bill sorting machine 100 can check whether networking is possible on its own, and if external device networking is not possible, banknote property information is stored in an external memory such as an SD card or USB for each bill type and face. Organize and store, or, if networking is possible on a PC (Personal Computer) or mobile device, save the banknote characteristic information by bill type or side on the PC or mobile device through a program in the PC or mobile device, and store the stored information later. Transmission to the server 300 in a networking environment, or transmission to the server through a general mobile communication network (eg, WiFi, 3G, 4G, 5G, LTE, etc.), or when an external network can be used, the bill corrector (100) After acquiring the information, it can be transmitted to the server 300 immediately. In addition, when localization is performed using a small computer device (eg, stick PC) in an environment where networking is not possible, the banknote sorter (100) based on the obtained bill information while the small computer device is connected to the bill sorter (100) ) First or partially localized quickly by matching processing with banknote discrimination programs and data previously stored in Localization processing can be performed on the server by matching with all country ticket types in the server.

As a result, the localization of the banknote sorting machine 100 is completed with the localized banknote discrimination program (ie, the program for banknote discrimination) and data.

2 is an exemplary diagram showing a schematic configuration of a reference banknote information localization system according to a second embodiment of the present invention.

As shown in FIG. 2 , the reference bill information localization system includes a bill sorter 100 , an information processing device 200 , and a server 300 . That is, compared to the embodiment shown in FIG. 1 , the embodiment shown in FIG. 2 further includes the information processing device 200 .

The information processing device 200 (eg, smart terminal, portable computer (notebook PC, stick PC, etc.), mobile terminal, personal portable terminal, etc.) uses a wired or wireless communication method through a built-in communication module (not shown). It is possible to access the server 300 by

The information processing device 200 is wired or connected through an I/O interface unit (not shown) (eg, USB port, HDMI port, serial port, parallel port, infrared module, NFC module, Bluetooth module, etc.) built into the information processing device 200. It can be connected to the I/O interface (not shown) of the bill sorting machine 100 in a wireless communication method.

The information processing device 200 may transmit reference bill information obtained from the bill sorting machine 100 to the server 300 by using a communication function. In addition, the information processing device 200 uses a data processing function to directly reflect the local characteristic information (i.e., sensor data) for each bill type instead of the function of the server 300, and directly to the banknote discrimination program ( That is, a program for banknote discrimination) and data may be localized, and a local banknote sorting machine may be localized with the localized banknote discrimination program and data.

Of course, by transmitting the localized banknote identification program and data to the server 300 through the information processing device 200, localization is performed by comparing with the unique characteristic information of the denomination stored in the server, or the banknotes of other regions or countries are examined. It can also be localized.

However, in order to perform the localization work of the banknote sorting machine 100 as described above, it is necessary to acquire as much valid reference banknote information as possible. To this end, it is desirable for a professional worker (ie, A/S worker) to go on a business trip to the local area, but as already presented as a problem in the background art, the method using a professional worker (ie, A/S worker) is very cumbersome, and many It takes manpower, time and money.

Therefore, in this embodiment, even a general user can acquire as much effective reference bill information as possible in an interactive manner. To this end, the bill sorting machine 100, as shown in FIGS. 3 to 5, A configuration (eg, tutor interface unit 120) that provides a function (hereinafter referred to as a tutor interface function in this embodiment) that allows a user to easily acquire (or collect) reference banknote information interactively may be included separately.

FIG. 3 is an exemplary view showing a schematic configuration of a banknote sorting machine according to the first embodiment in the system for localizing reference banknote information according to an embodiment of the present invention.

The control unit 110 performs a bill discriminating function in the first mode (ie, bill discriminating mode) as in a normal bill sorting machine.

In addition, in this embodiment, the controller 110 performs a function for obtaining reference banknote information (ie, information for banknote discrimination) in the second mode (ie, reference banknote information acquisition mode). In this case, the second mode may have a different name, and may be referred to as a reference banknote information localization mode.

Functions for acquiring the reference banknote information include a function of detecting characteristic information (i.e., sensor data) of banknotes for each denomination type, and guidance (or instructions) on actions (or actions) to be performed by the user to acquire valid reference banknote information. A function to verify whether reference bill information has been appropriately acquired according to the above guidance and to guide re-acquisition if it is incorrect, a function to filter the characteristic information of the detected bill for each bill type (e.g., frequency analysis, similarity map, a function of filtering valid characteristic information through image analysis), a function of storing or transmitting the detected characteristic information of banknotes for each denomination type in a designated device (eg server, internal memory, information processing device, etc.) It includes the ability to communicate with a designated device (eg server, internal memory, information processing device, etc.) to transmit characteristic information of

The tutor interface unit 120 outputs a message guiding (or instructing) a task (or action) to be performed by the user to obtain valid reference banknote information through the message output unit 160 .

The type of message output through the message output unit 160 may be text, video, audio, or a combination thereof.

Meanwhile, in the present embodiment, the tutor interface unit 120 is described based on being built inside the banknote sorting machine 100, but a separate device (eg, a tutor program installed in a PC, the Internet web (WEB), a smart terminal) It is also possible to output a guide (or) message through an application (APP), etc.), or to control the bill sizer 100 itself to operate in the second mode (banknote information acquisition mode).

The guide (or instruction) message to be output through the tutor interface unit 120 is basically output under the control of the control unit 110 according to a preset program, but the information processing device 200 or the server 300 ), when real-time communication is possible, messages corresponding to various situations (or error situations) occurring in the process of obtaining reference banknote information are output under the control of the information processing device 200 or the server 300. may be

The banknote inserting unit 130 receives banknotes for obtaining reference banknote information. When the operation for acquiring the reference banknote information is started, the banknotes are input into the banknote inserting unit 130 one by one or stacked in a large amount are entered into the banknote sorting machine 100 one by one at high speed (eg, 100 to 2000 sheets per minute). etc.) are transferred.

The banknote detection unit 140 transmits the characteristic information of the banknotes transferred one by one to at least one sensor (eg, ultrasonic wave (US : UltraSonic) sensor, ultraviolet (UV: UltraViolet) sensor, magnetic (MG: MaGnetic) sensor, contact image sensor (CIS: Contact Image Sensor), etc.) Here, the image sensor includes a multi-wavelength light source.

The operation unit 150 receives an operation command or instruction input by a user for menu selection or mode selection (eg, banknote discrimination mode, reference banknote information acquisition mode, etc.) of the banknote straightening machine through an input means. For example, the input means includes physical keys (eg, buttons, switches, etc.) and software keys (eg, touch, motion, etc.).

The message output unit 160 outputs a message output from the tutor interface unit 120 to guide the user in the form of text or image. For example, the output message includes the type of ticket to be inserted, the input direction (eg horizontally or vertically), the input side (eg A side, B side), the input location (eg middle, left end, or right end close), repeated input The number of times (e.g. 5 times), etc. are included.

The message output unit 160 may output a message guiding (or instructing) a task (or action) to be performed by the user in the form of voice or sound in the language of the country in association with the video output.

However, in order to acquire the reference banknote information, a maximum of tens to hundreds of banknotes may be continuously inserted at least once. Even if output, there is a possibility that general users may or may not accurately insert banknotes according to the guidance (or instructions). Therefore, it is necessary to check whether a general user correctly inserts banknotes according to the guidance (or instructions).

Therefore, in this embodiment, according to the guide (or instruction) output through the tutor interface unit 120 (or tutor program), it is possible for a general user to check whether banknotes are accurately inserted at each stage of execution. As shown in FIG. 4, 100 indicates the type of banknote to be inserted, the input direction (eg horizontally or vertically), the input side (eg A side, B side), and the input position (eg center, left end). Alternatively, a bill photographing unit 170 may be further included to check the number of inputs (eg, 5 times), etc.

FIG. 4 is an exemplary diagram showing a schematic configuration of a bill sorting machine according to a second embodiment in a system for localizing reference bill information according to an embodiment of the present invention. Compared to the embodiment shown in FIG. 3, FIG. The illustrated embodiment further includes a banknote photographing unit 170 .

The banknote photographing unit 170 is a device capable of photographing the entire section of the banknote inserting unit 130 (ie, from the left end to the right end of the entrance where the bill is inserted), and a line scanner (not shown) or an image sensor ( not shown) may be included.

The bill photographing unit 170 may photograph the bill to be inserted as a color or black-and-white image.

When the banknote photographing unit 170 is driven, the control unit 110 can control the banknote insertion speed or the banknote transfer speed, and also operates the banknote transport speed at a low speed when switching to a mode for localization of banknote property information. By increasing the sensing time of various sensors, precise sensing is possible, and through this, the effective information determination rate of banknotes can be further improved. More specifically, when changing the mode, the bill processing speed of the bill sorting machine 100 is changed to a low speed (for example, if the processing speed is 1200 NPM (Note Per Minute) (20 sheets per second) in the general mode), the bill characteristic information By processing banknotes, the various sensors of the banknote detection unit 140 have 10 times higher precise sensing data ( That is, high-resolution images and sensing data, etc.) can be obtained, and since the validity determination (processing) time of reference banknote information is secured by 10 times, the reliability of effective reference banknote information can be increased.

The control unit 110 may also selectively drive the banknote photographing unit 170 only in the second mode (ie, the reference banknote information acquisition mode).

The control unit 110 may convert the banknote characteristic information detected through the banknote detecting unit 140 with reference to the image photographed through the banknote photographing unit 170 .

For example, the detected banknote characteristic information may be automatically converted into left/right conversion, forward/backward conversion, up/down conversion, or other banknote characteristic information capable of supplementing the reference banknote information detected by the banknote detecting unit 140.

However, when a bill whose characteristics cannot be corrected through simple conversion as described above (eg, a torn bill, a partially folded bill, a bill of a different denomination, etc.) is inserted, the control unit 110 operates the tutor interface unit 120 Through this, a guide (or instruction) message can be output to remove or replace the corresponding banknote (a banknote for which valid banknote characteristics cannot be detected). In addition, the control unit 110 may discharge the corresponding banknotes (banknotes whose valid banknote characteristics cannot be detected) through a discharge unit (not shown) of the banknote sorting machine 100 .

5 is an exemplary view showing a schematic configuration of a bill sorting machine according to a third embodiment in a reference bill information localization system according to an embodiment of the present invention, compared to the embodiment shown in FIG. 4, in FIG. The illustrated embodiment further includes a storage unit 180 .

The storage unit 180, in order to obtain the reference banknote information, the banknote characteristic information (i.e., sensor data) detected through the banknote sensor 140 and the banknote image captured through the banknote photographing unit 170 Correspond to each other and save. At this time, the data to be stored may be compressed or encrypted before being stored.

The storage unit 180 includes an internal memory and an external memory.

At this time, the external memory includes a dedicated memory such as an SD memory and a USB memory, or an external device that is directly interfaced by being connected to the I/O port of the bill sorting machine 100 (e.g., smart terminal, portable computer (notebook PC, stick) PC, etc.), mobile terminal, personal portable terminal, etc.) may include memory.

As described above, information stored in the storage unit 180 (that is, banknote characteristic information and banknote image) is stored in the information processing device 200 or server 300, if necessary, according to a method for checking transmission history, etc. when the banknote scanner is networked. ) is sent to

The control unit 110 stores the information (ie, banknote characteristic information and banknote image) in the storage unit 180 or transmits the serial number of the banknote sizer before transmitting it to the information processing device 200 or server 300. It can be encrypted using unique information such as , serial number, MAC address, etc., encrypted using an arbitrary encryption algorithm, or compressed in an encrypted state.

6 is a flowchart illustrating a control method of a bill sizer in the system for localizing reference bill information according to an embodiment of the present invention.

As shown in Fig. 6, the bill sorting machine 100 (actually, the control unit of the bill sorting machine) detects whether a mode for obtaining reference bill information (ie, a reference bill information acquisition mode) is selected (S101). .

When the reference bill information acquisition mode is selected as described above, the bill sorting machine 100 outputs a guide (instruction) message through the tutor interface (S102).

The tutor interface (or tutor program) outputs a guiding (or instructing) message in the form of a combination of text, image, voice, video, etc. so that even a general user can easily acquire (or collect) reference banknote information.

In this embodiment, the tutor interface (or tutor program) may be referred to as a user interface (or UI program).

According to the output of the guide (or instruction) message, the bill sorting machine 100 detects whether bills are inserted into the bill input unit 130 (S103).

Usually, the banknotes are fed continuously, but may be fed individually.

The bill sorting machine 100 acquires reference bill information (S104).

The reference banknote information is banknote characteristic information, and the user accurately inserts banknotes according to the sensing information detected through the banknote detector 140 and a guide (or instruction) message output through the tutor interface (or tutor program). Information (eg, banknote photographed image) may be included to confirm whether the

The banknote sorting machine 100 filters the acquired banknote characteristic information (S105).

That is, the banknote sizer 100 performs filtering, which is a primary discrimination power test (this has already been described above, so a detailed description thereof will be omitted) and extracts only valid banknote characteristic information.

For example, banknotes that do not correspond to the guide (or instruction) message output through the tutor interface (or tutor program) have been inserted, or banknotes for which banknote property information is not available (eg, torn banknotes, partially folded banknotes, banknotes of different denominations) When banknotes, etc.) are inserted, only effective banknote characteristic information is extracted by excluding the banknote characteristic information detected from these banknotes.

At this time, the filtering (primary discrimination power verification) of the banknote characteristic information checks the degree of skew and checks overlap as described in the example above, and any one of frequency similarity analysis, similarity map analysis, image similarity analysis method, and other characteristic similarity analysis You can use one to check whether it is the same side/type of ticket.

The banknote sorting machine 100 encrypts the filtered valid banknote characteristic information using unique information such as the serial number, manufacturing number, and MAC address of the bill sorting machine or encrypts it using an arbitrary encryption algorithm ( S106).

Then, the banknote sorting machine 100 stores the encrypted valid banknote property information in the storage unit 180 or transmits it to an external device (eg, external memory, information processing device 200 or server 300, etc.) (S107).

7 is a flowchart illustrating a method of controlling a server in a reference banknote information localization system according to an embodiment of the present invention.

As shown in FIG. 7 , the server 300 collects reference bill information transmitted from the bill sorting machine 100 (S201).

At this time, at least one banknote sorter 100 may be provided depending on the region or country in which it is installed. Accordingly, the server 300 may classify and collect the collected reference banknote information by type (eg, by region, by country, by bill type, etc.).

As already described above, the reference banknote information is banknote characteristic information, and the user receives information according to the sensing information detected through the banknote detection unit 140 and the guide (or instruction) message output through the tutor interface (or tutor program). Information (e.g., a photographic image of a bill) may be included to confirm whether bills have been inserted correctly.

The server 300 extracts unique banknote characteristic information for each banknote type of a corresponding region or country from the collected reference banknote information (S202).

At this time, in extracting the banknote characteristic information unique to each denomination, the method for extracting the banknote characteristic information is not limited. method, histogram feature extraction method, 8-way chaincode feature extraction method, gradient feature extraction method using Sobel operator, SVM (Support Vector Machine), neural network genetic algorithm, machine learning (machine learning) program, etc. can be used.

The server 300 checks (verifies) whether the extracted banknote characteristic information unique to each denomination has discriminative power against the banknote characteristic information of other denominations in the corresponding region or country, and also checks (verifies) whether the banknotes by denomination of different regions or countries in the world. It is also checked (verified) whether the feature information has discriminative power (S203). Here, since discrimination power verification in the server has been described in detail in the above embodiment, a description thereof is omitted for convenience in this embodiment.

The discriminative power check (verification) for the banknote characteristic information unique to each denomination may be repeatedly performed at least once.

The server 300 determines the banknote characteristic information for which the discrimination power has been checked (verified) as unique banknote characteristic information of the corresponding denomination (S204).

At this time, the server 300 localizes the banknote discrimination program and data of the banknote sorting machine of the corresponding region or country by reflecting the banknote characteristic information unique to the determined denomination, and converts the localized banknote discrimination program and data to the corresponding region. Localization of the corresponding bill sorting machine 100 is performed by transmitting the localization to the bill sorting machine of the country or the country (S205).

At this time, in order to localize the bill sorting machine 100, first, the information of the server 300 itself is localized, and then the localization work of the bill sorting machine 100 is performed.

Hereinafter, a more detailed description will be made using the captured screen of the driving example of the tutor interface (or tutor program).

8A to 8C are exemplary diagrams showing screen captures of the tutor interface (or tutor program) output from the reference banknote information localization system according to an embodiment of the present invention.

The tutor interface (or tutor program) is basically a function that enables easy acquisition (or collection) of reference bill information for general users who are not professional workers (ie, A/S workers), but the target must be It is not limited to general users.

Therefore, the tutor interface (or tutor program) substantially includes an expert mode and a general public mode, and in the case of the expert mode, various option keys and selection keys for obtaining reference bill information are included as shown in FIGS. 8A to 8C. The control unit 150 is displayed, and in the case of the general public mode, only simple keys for confirming the user's recognition, such as a confirm key and a cancel key, among the keys included in the control unit 150 are configured to be displayed. However, the guide (or instruction) message displayed on the message output unit 160 may be displayed differently depending on whether the tutor interface (or tutor program) is in expert mode or general public mode.

The message output unit 160 divides the display area and displays information such as a guide (or instruction) message or result in different divided areas or in a pop-up manner. In addition, when a user inputs a command to take an action according to the guided instruction, the displayed message automatically disappears, and the result guide is implemented in a way that the user clicks or touches an OK button.

For example, a guide (or instruction) message related to the banknote input method and/or acquired image (front/rear) information of the inserted banknote is displayed in the first partition area 161, and banknote characteristic information obtained by analyzing the inserted banknote is displayed in the second partition area 161. , It is displayed in the third partition area (162, 164), and if there is an event that occurs during localization, analysis results, and a task to be performed after receiving confirmation from the user, a separate pop-up message (163) is used to guide (or instruction) to display a message or information.

For reference, FIG. 8A is an exemplary diagram capturing a screen in which the server 300 and the bill sorting machine 100 are network-connected for localization of reference bill information, and FIG. 8C is an example of capturing a screen where the network connection is successfully completed and the result is displayed through the pop-up message 163, and FIG. Referring to FIG. 8C as an example diagram capturing the displayed screen, when the characteristic information of the banknote inserted by the user is acquired (collected) according to the instructions of the guide message, the second and third partitioned areas 162 and 164 are unique. One banknote characteristic information (i.e., sensor data obtained from various sensors) is displayed.

At this time, the banknote property information is numerically displayed in the second partition area 162, and the banknote property information is displayed in a graph form in the third partition area 164 so that the user can intuitively check the banknote property information. do.

On the other hand, the first partition area 161 displays a guide (instruction) message related to the banknote insertion method as an image or video before banknote insertion, but after obtaining banknote specific information, the acquired image (front/back side) of the inserted banknote ) is displayed, and in particular, information about the cause is displayed when the banknote property information has not been successfully obtained. For example, when an abnormal bill is inserted, bills are not inserted correctly, there is an error in the bill straightening machine itself, or bills are not inserted according to the instructed method, the user is notified of this, so that specific information on bills is obtained when the next bill is inserted Acquisition can be successful.

Here, as shown in FIGS. 1 and 2 , when the bill sorting machine 100 is directly or indirectly connected to the server 300 through a network, the localized bill discrimination program from the server 300 And by receiving and localizing data, localization of the corresponding banknote sorting machine 100 can be performed.

Additionally, when there is a localization event, the server 300 connected to the bill sorting machine 100 through a network sends a push message to the bill sorting machine 100 to notify that there is localization, Depending on the setup information, the banknote identification program and data can be localized automatically or with user confirmation (OK).

If the bill sorting machine 100 cannot be networked with the server 300, a separate dedicated memory (eg SD memory, USB memory, etc.) or an external device (eg smart terminal, portable computer (notebook PC, stick) PC, etc.), mobile terminal, personal portable terminal, etc.) can be localized by storing the banknote discrimination program and data in the memory.

As described above, the present embodiment enables interactive acquisition of valid reference bill information for a remotely installed bill sorting machine, so that the localization of the bill sorting machine can be performed simply and quickly with less manpower, time, and cost. .

The present invention has been described above with reference to the embodiments shown in the drawings, but this is only exemplary, and those skilled in the art can make various modifications and equivalent other embodiments. you will understand the point. Therefore, the technical protection scope of the present invention should be determined by the claims below.
