When the POS system 1 is constructed in the third form, the first functional unit 1c, the second functional unit 1d, and the third functional unit 1e can be incorporated into the control unit of the POS terminal device as they are.

The control unit of each device can be realized by, for example, a CPU (Central Processing Unit), a working memory, a non-volatile storage device that stores a program, or the like. It can be said that this program includes a program (subprogram) for executing a process for realizing the functional unit of the device. It should be noted that the control unit of each device, for example, an integrated circuit can be included in the configuration.

Next, with reference to FIG. 2, a processing example in the POS terminal device in the POS system 1 will be described. FIG. 2 is a flow chart for explaining an example of a processing method in the POS terminal device in the POS system 1.

This processing method includes a first display step (step S1), an input step (step S2), and a second display step (step S3) executed by the POS terminal device provided with the operation input unit 1a. The above program in the POS terminal device is, for example, a program for causing a computer such as a CPU provided in the POS terminal device provided with the operation input unit 1a to execute steps S1, S2, and S3. can do.

In step S1, an operation image for operating the POS terminal device is displayed on the operation input unit 1a. In step S2, the content of the received operation is input while the operation image is displayed. In step S3, the operation input unit 1a displays the result of executing the next process with the authentication process of accessing DB1b and performing authentication based on the account information. In the above process, based on the content of the operation input in the input step, the product information about the product to be purchased is registered in DB1b and the registered product information is accounted for. As described above, the DB 1b stores information including product information and account information including information indicating a user who operates the POS terminal device.

It can be constructed only by changing the arrangement of functional parts using ~ 1e. Each of the functional units 1c to 1e can be substantially realized by a program.

As described above, in the POS system 1 according to the present embodiment, even if the physical arrangement between the devices constituting the system is changed, it can be applied only by changing the arrangement without changing the program. It has the effect of being able to freely design the composition. Further, according to the present embodiment, it is possible to reduce the implementation of software by the same effect, and it is possible to improve the efficiency of development resources. The POS system 1 can be constructed not only as a system used in a store such as a convenience store, but also as another system such as a system for eating out.

The POS function service 33 is a process that is responsible for all the functions of the POS, and can be referred to as a POS processing unit or a POS business logic. The POS function service 33 is an example of the second program 14 or the process executed by the second program 14. The POS function service 33 distributes an input / output image (screen content) which is a user I / F image to the POS screen input / output service 34, and information from the DB 32 based on the information input by the POS screen input / output service 34. Acquires and registers, and also performs other operations. In addition to the calculation of the difference between the deposit and the change, the calculation here can be performed when the information to be registered in the DB 32 is obtained by the calculation from a plurality of information.

The POS screen input / output service 34 can include a function of displaying an input / output image (user I / F image) for inputting / outputting information necessary for a POS function on the touch panel unit 20. The POS screen input / output service 34 is an example of the first program 13 or the processing executed by the first program 13. For example, the POS screen input / output service 34 can be configured such that the control unit 11 of any one of FIGS. 3 to 5 cooperates with the touch panel unit 20 to execute the first program 13. The POS screen input / output service 34 provides information necessary for the function of the POS, for example, authentication information for authenticating a user (for example, an authentication ID also called a login ID and a password corresponding to the authentication ID), and a store clerk as a product. You can enter the information of. The POS screen input / output service 34 can display, for example, an operation for performing accounting and information related thereto as information necessary for the function of the POS.

Further, the POS screen input / output service 34 can include a function of passing the user's touch input operation received by the touch panel unit 20 to the POS function service 33. As described above, the POS screen input / output service 34 can refer to a function of displaying a screen required as a POS function on a display device with a touch function and accepting input, and input / output processing is performed in cooperation with the touch panel unit 20. I do. The POS screen input / output service 34 can be referred to as an input / output processing unit (or operation processing unit).

The authentication service 35 includes a function of performing comparison with the account information stored in the DB 32 based on the authentication information (for example, the authentication ID and password) input in the POS screen input / output service 34, and performing the authentication process. Can be done. The authentication service 35 is an example of the third program 15 or the process executed by the third program 15. The authentication service 35 can be referred to as an authentication unit or an account control service. In addition, the authentication service 35 may include a function of authenticating the peripheral device service 31 (and the peripheral device 21) and the external input / output device 22.

The external input / output device 22 is a group of devices that input / output information for the user of the POS terminal device (any of the POS terminal devices 10a, 10b, and 10c) in the POS system 30. The external input / output device 22 is a device that can operate independently and can directly communicate with the POS function service 33 from the outside via a network or the like. The external input / output device 22 can be directly controlled from the POS function service 33 by the operation of the POS screen input / output service 34. As described above, the external input / output device 22 is a peripheral device that does not use the peripheral device service 31 unlike the peripheral device 21.

The external input / output device 22 may include one or more of the handy terminal 22a, the kitchen printer 22b, the kitchen display 22c, and the self-order terminal 22d. However, the self-order terminal 22d is used as a terminal for the customer to input. The handy terminal 22a is a terminal for inputting product information in the same manner as the input in the touch panel unit 20 and the POS screen input / output service 34. The kitchen printer 22b and the kitchen display 22c are used in restaurants, and can be used for printing and displaying ordered menus, respectively. The kitchen printer 22b is a printing device that prints receipts on a kitchen or the like, and the kitchen display 22c is a display device that gives cooking instructions to the kitchen.

Since the external input / output device 22 is a device controlled independently of the POS terminal devices 10a, 10b, 10c, the POS terminal devices 10a, 10b, 10c are used in order to use the external input / output device 22. It is not necessary to change the configuration of. The external input / output device 22 executes an input / output program stored in its own storage unit, and cooperates with the POS terminal device 10c, the local server 25, or the POS function service 33 in the cloud server 24 to obtain information. Perform input / output.

As the peripheral device 21 used via the peripheral device service 31, the device having the functions of the devices 22a to 22d exemplified as the external input / output device 22 (however, the device used by connecting to the peripheral device service 31). ) May be provided. Of course, in this case, these devices are treated as peripheral devices 21 to the last.

As described above, in the POS system 30, the POS screen input / output service 34 (and the peripheral device service 31) is divided into the POS function service 33, the authentication service 35, and the DB 32, which are other services. Then, the POS function service 33 is accessed by the operation input input by the POS screen input / output service 34, and the POS screen input / output service 34 is made to perform display control through the authentication process by the authentication service 35. Further, the data is input through the POS function service 33 by the operation input of the product order input by the POS screen input / output service 34, the data is stored in the DB 32 through the POS function service 33 after the authentication process by the authentication service 35. .. Here, the POS function service 33 can be configured on the cloud server 24. Further, when the peripheral device service 31 is provided, the peripheral device 21 such as the receipt printer 21b can be operated via the peripheral device service 31 through the POS function service 33.

Further, the description has been made on the premise that the peripheral device service 31 and the POS screen input / output service 34 can be operated independently of other services. However, by enabling the peripheral device service 31, the DB 32, the POS function service 33, the POS screen input / output service 34, and the authentication service 35 to operate independently of each other, the versatility of the arrangement is further enhanced.

Next, an example of processing during operation in the POS system 30 will be described with reference to FIGS. 7 to 16. Here, basically, any of the third form to the first form will be described without distinction, and specific examples of arrangements and processes (procedures) peculiar to each form will be described later with reference to FIGS. 17 to 20.

First, an example of POS screen input / output processing will be described with reference to FIG. 7. FIG. 7 is a flow chart for explaining an example of POS screen processing (POS screen input / output processing) in the POS system 30. In the flow chart of FIG. 7 and the like, some branching of the determination process is omitted due to space limitations.

When the POS system 30 is activated, the POS screen input / output service 34 displays a login image (login screen) on the touch panel unit 20 (step S11), and accepts input of authentication information (authentication ID and password) from the user. The POS screen input / output service 34 transmits (issues) an authentication service request based on the input information to the POS function service 33 (step S12). In step S12, other services are also described for convenience, and steps S18 and S21 in FIG. 7 are also briefly described including processing for other services or devices.

The POS function service 33 that received the authentication service request in step S12 sends an authentication service login request (in this case, a POS login request) to the authentication service 35. Upon receiving this request, the authentication service 35 refers to the account information of the DB 32, performs the authentication process by comparing the authentication information with the account information, stores the authentication result (success / failure) in the DB 32, and is a POS function service. Return to 33. The authentication service 35 may store that fact in the DB 32 only when it is authenticated. The processing in the authentication service 35 will be described later with reference to FIG. 8 and the like. The POS function service 33 transfers the authentication result to the POS screen input / output service 34.

The POS screen input / output service 34 determines success / failure of authentication based on the authentication result (step S13), and if it is successful, displays the operation menu on the touch panel unit 20 (step S14). If the authentication fails (NO in step S13), the operation of the POS system 30 cannot be performed at this point, and the POS screen input / output service 34 returns to step S11, at which time the correct authentication ID and password are used. It is advisable to ask the user for the input of. The POS screen input / output service 34 may adopt a configuration in which information is directly exchanged with the authentication service 35. In that case, the authentication service request is directly transmitted from the POS screen input / output service 34 to the authentication service 35. And the result will be sent back directly.

The operation menu displayed in step S14 can include a transition button to a product input screen, an accounting screen for deposit input, an accounting screen for displaying other information (change amount, etc.), and the like. When the transition button of the product input screen is selected in the operation menu, the POS screen input / output service 34 displays the product input screen and accepts the input of the product information (step S17). The POS screen input / output service 34 transmits an order registration request for registering the order contents to the POS function service 33 based on the input information (step S18). After the process of step S18, if a process such as cancellation is performed, the process returns to step S14 and the operation menu is displayed. If not, the process proceeds to step S20 and the input of the deposit described later is accepted.

The POS screen input / output service 34 displays the accounting screen when the accounting screen display operation a is performed in the operation menu, specifically, when the transition button of the accounting screen for deposit input is selected (step S19). Then, the input of the deposit is accepted (step S20). The display of the accounting screen can be performed by issuing an accounting screen display request to the POS function service 33 and obtaining the response. Next, the POS screen input / output service 34 transmits an accounting request for performing accounting processing based on the information of the input amount to the POS function service 33 (step S21). After the processing of step S21, if the processing such as cancellation is performed or the processing of step S19 is performed (when the processing of step S20 is performed without going through step S18), the process returns to step S14 and the operation menu is displayed. To. If not, after the process of step S21, the process proceeds to step S23, and the change amount and the like described later are displayed. The requests in steps S18 and S21 are examples of POS function service requests described later.

In the POS screen input / output service 34, when the accounting screen display operation b is performed in the operation menu, specifically, when the transition button of the accounting screen for displaying the change amount or the like is selected (step S22), the change amount or the like. The accounting screen including the above is displayed (step S23). The display of the accounting screen can be performed by issuing an accounting screen display request to the POS function service 33 and obtaining the response. It is normal that step S23 is processed after the processing of step S21, and in this case, the change amount or the like as a result of accounting processing by the POS function service 33 is displayed in step S23. In addition to the change amount, for example, input of information on points that can be used for payment may be accepted instead of the price. After the process of step S23, the process returns to step S14 and the operation menu is displayed.

The POS screen input / output service 34 outputs a report when a report output operation is performed in the operation menu (step S24) (step S25). Examples of the report referred to here include a total report on sales used by stores, and the POS screen input / output service 34 can be performed by issuing a report output request to the POS function service 33. After the process of step S25, the process returns to step S14 and the operation menu is displayed. In addition, other POSs not shown and processes related to maintenance of store operation can be selected from the operation menu, and the corresponding POS operations are carried out by this selection.

When the logoff operation is performed in the operation menu (step S15), the POS screen input / output service 34 instructs the POS function service 33 to log off (not shown), hides the operation menu, and ends the process. Here, for example, it is possible to return to the login screen of step S11. In either case, if the logoff operation is performed, the operation cannot be performed unless you log in again.

Next, an example of the authentication process in the authentication service 35 will be described with reference to FIGS. 8 to 10. 8 is a flow chart for explaining an example of authentication service request reception processing in the processing of FIG. 7, FIG. 9 is a diagram showing an example of an account table used in the processing of FIG. 8, and FIG. 10 is a processing of FIG. It is a figure which shows an example of the peripheral device service account table used in.

The authentication service 35 receives the authentication service request (step S31), and performs the operations as described below in response to the received request. When the POS login request, which is the request from the POS function service 33 described in step S12, is received, the authentication service 35 executes the POS login process (step S32). This POS login request includes the authentication ID and password entered at logon in the POS screen input / output service 34, as well as information indicating the store to log in to and the tenant to which the store belongs (the tenant to which the store resides). Can be done. It should be noted that here, an example in which the tenant is also taken into consideration is given, and such an example is given below, but the processing only in the store can be adopted.

In the POS login process, the authentication service 35 authenticates the information included in the POS login request by using the account information such as the account table for which the contents are exemplified in FIG. 9 stored in the DB 32. In this authentication, it is checked whether or not the information included in the POS login request matches the store, tenant, authentication ID, and password shown in FIG.

Then, if they match (that is, if the authentication is successful), the authentication service 35 issues the token and sets the expiration date of the token based on the validity period and the current time predetermined in the DB 32. The issuance of the token and the setting of the expiration date thereof can be executed by the authentication service 35 storing it in the above account table of the DB 32 via (or directly) the POS function service 33. Here, even if it is already recorded, the token and the expiration date may be overwritten.

After the processing of step S32 and any of steps S33 to S37 described later, the authentication service 35 transmits a response to the request to be processed to the POS function service 33 (step S38). This response includes response data for each request and is passed from the POS function service 33 to the POS screen input / output service 34 or the peripheral device service 31. As a response to the POS login process, if they match, an authentication is successful, and if they do not match, an error is sent to the POS function service 33.

When the POS logoff request is received in step S31, the authentication service 35 executes the POS logoff process (step S33). The POS logoff request can be transmitted from the POS function service 33 to the authentication service 35 in response to the logoff instruction to the POS function service 33 made in step S15, for example.

In the POS logoff process, it is checked whether or not the requested store and tenant are logged in at the time of logoff in the POS screen input / output service 34. If you are logged in, delete the corresponding token and expiration date of DB32 (for example, the account table in FIG. 9) and log off. On the other hand, if the token is not recorded in the DB 32 at the time of the POS logoff request, or if the current date and time has passed the expiration date, the logoff process is interrupted. When the logoff process is interrupted, an error is transmitted to the POS function service 33 as a response in step S38. In this case, an error is passed to the POS screen input / output service 34, and the touch panel unit 20 can display the error. When the logoff state is reached, in step S38, the fact that the logoff has been made is transmitted to the POS function service 33 as a response.

When the POS login check request is received from the POS function service 33 in step S31, the authentication service 35 executes the POS login check process (step S34). The POS login check request can be transmitted to the POS function service 33 by an operation from the POS screen input / output service 34, and can include information indicating a store, a tenant, and an authentication ID. In the POS login check process, it is determined whether or not the account corresponding to the tenant, store, and authentication ID included in this request is in the logged-in state. The information indicating whether the user has logged in or has not logged in, which is the determination result, is transmitted as a response in step S38.

When the peripheral device service login request is received from the POS function service 33 in step S31, the authentication service 35 executes the peripheral device service login process (step S35). The peripheral device service login request is sent by the peripheral device service 31 to the POS function service 33 at the start of use (at the time of the first login) or the like. The request may include information indicating a store, a tenant, a number of the peripheral service 31 and a password of the peripheral service 31.

In the peripheral device service login process, the authentication service 35 authenticates the initial and periodic logins from the peripheral device service 31 and manages logoff. Here, the peripheral device 21 can be authenticated by using the account information stored in the DB 32, such as the peripheral device service account table whose contents are illustrated in FIG. 10. In this authentication process, whether or not the information indicating the tenant, store, and peripheral device service numbers and their passwords included in the peripheral device service login request matches the peripheral device service account table as shown in FIG. To check. In addition, although the example which has a plurality of peripheral device services 31 is given in FIG. 10, it may be one as shown in FIG. Further, the IP (Internet Protocol) address of the peripheral device service 31 is also stored in the peripheral device service account table of FIG. 10 for communication, and the IP address may also be used for checking.

If they match, it is determined that there is no problem in logging in from the peripheral device service 31 (authentication success). If the login authentication is successful, the authentication service 35 stores the token and the expiration date in the peripheral device service account table. You can overwrite the token and expiration date even if it is already recorded. As a response to the peripheral device service login process, if they match, an authentication is successful, and if they do not match, an error is sent to the POS function service 33.

When the peripheral device service logoff request is received from the POS function service 33 in step S31, the authentication service 35 executes the peripheral device service logoff process (step S36). The peripheral device service log-off request is transmitted by the peripheral device service 31 to the POS function service 33, and may include information indicating a store, a tenant, a number of the peripheral device service 31, and a password of the peripheral device service 31. However, the information indicating the password may not be included. The peripheral device service logoff process is basically the same as the POS logoff process except that the target is different. If the logoff process is interrupted or does not need to be interrupted, the token and expiration date in the peripheral device service account table will be displayed. It will be deleted and you will be logged off. The response in step S38 related to the peripheral device service logoff process is basically the same as the POS logoff process.

When the peripheral device service login check request is received from the POS function service 33 in step S31, the authentication service 35 executes the peripheral device service login check process for checking the login status of the peripheral device service 31 (step S37). The peripheral device service login check request is transmitted by the peripheral device service 31 to the POS function service 33, and may include information indicating the numbers of the store, the tenant, and the peripheral device service 31.

In the peripheral device service login check process, it is determined whether or not the peripheral device service account corresponding to the store, tenant, and peripheral device service 31 numbers included in this request is logged in. In step S38, the information indicating whether the user is logged in or not logged in, which is the determination result, is transmitted to the POS function service 33 as a response together with the token if the user has logged in.

Next, an example of processing in the POS function service 33 will be described with reference to FIGS. 11 to 13. FIG. 11 is a flow chart for explaining an example of receiving processing of a POS function service request such as an order registration request and an accounting request (steps S18, S21) in the processing of FIG. 7.

The POS function service 33 receives a request from the POS screen input / output service 34 (step S41), and performs the operations as described below in response to the received request. When the authentication service request from the POS screen input / output service 34 in step S12 is received, the POS function service 33 issues (sends) an authentication service login request to the authentication service 35 based on the received authentication ID and password (send). Step S42). The authentication service 35 receives the authentication service login request and executes the POS login process (step S32).

Further, when the POS function service 33 receives a request other than the authentication service request (POS login request), the POS function service 33 checks a token that can be included in the request or can be received at the same time (step S43). Then, the POS function service 33 determines whether or not there is a valid token (OK) (step S44). The validity of the received token can be determined by whether or not it matches the issued token. If NO in step S44, the POS function service 33 returns an authentication failure response to the request source (step S45), and ends the process.

If the POS function service 33 fails to log in to the transmission of the authentication service login request, the token from the authentication service 35 cannot be received, so the result is NO in step S44. Therefore, in this case, the POS function service 33 returns an authentication failure response indicating a login failure to the POS screen input / output service 34.

On the other hand, if the login is successful, the POS function service 33 receives the token issued from the authentication service 35, becomes YES in step S44, and enters the login state (step S46). Next, the POS function service 33 transmits a response to the effect that the login is successful to the POS screen input / output service 34 (step S47), and ends the process.

When the POS logoff request is received in step S41, the POS function service 33 confirms the validity of the token by the token check process (steps S43 and S44). The POS logoff request is a kind of authentication service request, and can be issued to the POS function service 33 when the logoff operation (step S15) is performed in the POS screen input / output service 34. After the validity is confirmed, the POS function service 33 executes the logoff process (step S48). This logoff process can be a process of analyzing the logoff request and extracting the authentication ID or the like that was logged in. After that, the POS function service 33 issues an authentication service logoff request based on the authentication ID and the like to the authentication service 35 (step S49). The authentication service 35 receives the authentication service logoff request and executes the POS logoff process (step S33).

In steps S42 and S49, an example of shifting to the POS logon process and the POS logoff process has been given, but the authentication service login / logoff request may be made to the peripheral device service. In that case, the process shifts to the peripheral device service login process (step S35) and the peripheral device service logoff process (step S37).

When the product list display request for displaying the product list is received from the POS screen input / output service 34 in step S41, the POS function service 33 performs the product list DB acquisition process after the token check process (steps S43 and S44). Execute (step S50). This product list DB acquisition process is a process of acquiring a product list from the product list DB included in the DB 32. After that, the POS function service 33 returns the acquired product list to the POS screen input / output service 34 as a response (step S47). The POS screen input / output service 34 that received the reply causes the touch panel unit 20 or the like to display the product list. If the token check fails, the authentication failure response is transmitted to the POS screen input / output service 34 (step S45).

When the product input registration request for registering the product input is received from the POS screen input / output service 34 in step S41, the POS function service 33 executes the product input registration process after the token check process (steps S43 and S44). (Step S51). This product input registration process is a process of accepting a product input by the POS screen input / output service 34 (actually input by the touch panel unit 20 or the like). After that, the POS function service 33 executes a product input DB registration process for registering the product input contents to be registered in the DB 32 (step S52).

After that, before the start of cooking, the POS function service 33 executes a kitchen printer request process for instructing the kitchen printer 22b of a request for printing a cooking menu (step S53). Further, at the same time as or immediately before or immediately after step S53, the POS function service 33 executes a kitchen display request process for instructing the kitchen display 22c to make a request for displaying the cooking menu (step S54). In steps S53 and S54, not only the output destinations set in advance can be supported, but also operations such as changing the output destination kitchen printer 22b or kitchen display 22c according to the cooking menu or the like can be executed. Is preferable.

After the processing of steps S53 and S54, the POS function service 33 returns information indicating the executed processing content to the POS screen input / output service 34 as a response (step S47). If the token check fails, the authentication failure response is transmitted to the POS screen input / output service 34 (step S45).

When the accounting screen display request for displaying the accounting screen is received from the POS screen input / output service 34 in step S41, the POS function service 33 executes the accounting screen display process after the token check process (steps S43 and S44). (Step S55). This accounting screen display process can be performed with reference to the product registered in the DB 52 in step S52, and the information of one or a plurality of registered products can be included in the accounting screen. In the accounting screen display process, the accounting screen can be displayed on the touch panel unit 20 or the like by returning a response to the POS screen input / output service 34. After the process of step S55, the POS function service 33 obtains the price information and the tax rate information of the product with reference to the DB 32, and performs the sum / tax calculation / discount calculation process (step S56). This calculation process includes processing such as tax calculation and discount calculation in addition to the calculation of the total product. As a result, the accounting screen can be displayed on the touch panel unit 20 or the like by returning a response to the POS screen input / output service 34.

Next, the POS function service 33 executes the payment terminal request processing when making a payment using the payment terminal 21e (step S57). In the payment terminal request processing, a transmission request is transmitted to the peripheral device service 31 in order to transmit the payment amount and the like to the payment terminal 21e. After the process of step S57, the POS function service 33 transmits a response such as information indicating that the payment amount or the like has been transmitted to the POS screen input / output service 34 (step S47). If the token check fails, the authentication failure response is transmitted to the POS screen input / output service 34 (step S45).

When the POS screen input / output service 34 receives the accounting screen display request for displaying the accounting screen for the entered deposit in step S41, the POS function service 33 performs the token check process (steps S43 and S44). Run. After that, the POS function service 33 executes the accounting screen display process for the deposit (step S58). This accounting screen display processing includes the same processing if step S55 is before execution, and includes the amount of deposit included in the accounting screen display request in the accounting screen. In this accounting screen display process, the accounting screen including the deposit information can be displayed on the touch panel unit 20 or the like by returning a response to the POS screen input / output service 34. After the process of step S58, the POS function service 33 executes the same process if step S56 is not executed, and then performs a change calculation process of subtracting the calculation result from the deposit (step S59).

Next, the POS function service 33 registers the data at the time of accounting in the accounting information DB included in the DB 32 (step S60). The data at the time of accounting is stored in the accounting information DB as electronic journals and transaction data, so that it can be referred to later when the report is output. Next, the POS function service 33 executes the receipt printer request process (step S61). In the receipt printer request processing, a print request for printing the contents such as a receipt and a receipt on the receipt printer 21b is transmitted to the peripheral device service 31. As a result, the receipt can be printed from the receipt printer 21b. After the process of step S61, the POS function service 33 transmits a response such as information on the change calculation result in step S59 and information indicating that the print request has been transmitted to the POS screen input / output service 34 (step S47). If the token check fails, the authentication failure response is transmitted to the POS screen input / output service 34 (step S45).

When the report output request for performing the report output (step S25) is received from the POS screen input / output service 34 in step S41, the POS function service 33 executes the token check process (steps S43 and S44). After that, the POS function service 33 performs aggregation with reference to the accounting information DB so as to match the content of the report included in the report output request (aggregation of accounting information matching the period and other conditions, etc.) (step S62). ). In step S62, the POS function service 33 further registers the aggregated result in the report output DB included in the DB 32, and acquires the registered aggregated result. Next, the POS function service 33 transmits a response including the information of the aggregation result acquired in step S62 to the POS screen input / output service 34 (step S47). If the token check fails, the authentication failure response is transmitted to the POS screen input / output service 34 (step S45).

Next, regarding printing by the receipt printer 21b in step S61, an example of the table used in the process of FIG. 11 will be specifically described with reference to FIGS. 12 and 13. FIG. 12 is a diagram showing an example of a correspondence table for associating the peripheral device service used in the process of FIG. 11 with the peripheral device, and FIG. 13 is a diagram showing an example of the peripheral device service table used in the process of FIG. be.

The peripheral device service 31 to which the request to the peripheral device 21 such as the receipt printer 21b is transmitted can be specified as follows. First, the peripheral device service number is specified from the tenant, the store, and the POS number with reference to the peripheral device service-peripheral device correspondence table exemplified in FIG. Next, by using the peripheral device service table illustrated in FIG. 13 and specifying the IP address from the peripheral device service number, the specified IP address is determined as the transmission destination. The request to the peripheral device 21 is transmitted to the IP address of the destination determined in this way. By including the tables illustrated in FIGS. 12 and 13 in the DB 32, the peripheral device service 31 can be referred to via the POS function service 33.

The POS function service 33 determines which peripheral device 21 can be controlled by which peripheral device service 31 or which device of the peripheral device 21 is operated in response to the input from the POS screen input / output service 34. Can be done. For example, the POS function service 33 can execute this determination by using the correspondence table between the POS number and the peripheral device 21 of the control destination, which is set in advance in the corresponding store. By including such a correspondence table in the DB 32, the POS function service 33 can refer to it.

Next, an example of the authentication process in the peripheral device service 31 will be described with reference to FIG. FIG. 14 is a flow chart for explaining an example of the processing related to the peripheral device service (steps S35 to S37) in the process of FIG. 8, that is, an example of the peripheral device service authentication process.

The peripheral device service 31 is started for the first time or periodically after that (step S71), and executes the following processing after the start of operation or periodically. First, the peripheral device service 31 accesses the authentication service 35 based on its own ID and password, and executes an authentication request process for receiving authentication (step S72). Next, the peripheral device service 31 executes a token reception process of receiving and holding the responded token (step S73). In steps S72 and S73, a simplified example in which the peripheral device service 31 is directly connected to the authentication service 35 is described, but as described with reference to FIG. 6, both are connected via the POS function service 33. You may.

Further, when accessing the peripheral device service 31 from the POS function service 33, the POS function service 33 transmits a token other than the information for controlling the peripheral device 21. Then, the peripheral device service 31 may compare the received token with the token holding the token, and control the connected peripheral device 21 only when both match.

Next, an example of request reception processing in the peripheral device service 31 will be described with reference to FIG. FIG. 15 is a flow chart for explaining an example of a reception process for receiving a request (steps S57, S61) relating to the peripheral device service 31 in the process of FIG.

The peripheral device service 31 receives a request for controlling the peripheral device 21 (step S81), and executes the token check process in the same manner as in steps S43 and S44 (steps S82 and S83). In step S83, it is checked that the token received at login and the token given to the received request match, and it is determined whether or not they match. If the token check fails, an authentication failure response is returned (step S84), and the process ends.

If the token check is successful (YES in step S83), the peripheral device service 31 performs the operations described below in response to the received request. When the receipt printer request from the POS function service 33 described in step S61 is received, the peripheral device service 31 controls the receipt printer 21b according to the request (step S85). The control here includes an operation instruction for the receipt printer 21b, and is the same for the other peripheral devices 21. By operating the peripheral device 21 on a device such as a POS terminal device that directly controls the peripheral device 21, it is possible to control the peripheral device 21 via the OPOS interface. Further, by such an operation, it is possible to control the peripheral device 21 via another OS (Operating System) and a driver layer.

Further, when the drawer / change machine request from the POS function service 33 described in step S57 is received, the peripheral device service 31 controls the receipt printer 21b according to the request (step S86). When the payment terminal request is received, the peripheral device service 31 controls the payment terminal 21e according to the request (step S87).

When the kitchen printer request is received, the peripheral device service 31 controls the kitchen printer (not shown) included in the peripheral device 21 according to the request (step S88). When the kitchen display request is received, the peripheral device service 31 controls the kitchen display (not shown) included in the peripheral device 21 according to the request (step S89). In steps S88 and S89, the peripheral device service 31 can also transmit the request received from other than the POS function service 33 to the POS function service 33. As a result, the POS function service 33 can also transfer the target request to the kitchen printer 22b and the kitchen display 22c, respectively.

After any of the processes of steps S85 to S89, the peripheral device service 31 returns a response to the request to be processed (step S90), and ends the process.

Next, an example of device event reception processing in the peripheral device service 31 will be described with reference to FIG. FIG. 16 is a flow chart for explaining an example of reception processing in which the peripheral device service 31 receives an event (peripheral device event) from the peripheral device 21 in FIG.

The peripheral device service 31 receives an asynchronous peripheral device event or a synchronized peripheral device event from the peripheral device 21 (step S91). When an event from the peripheral device 21 is transmitted to the peripheral device service 31, it can be notified by using a technique such as WebSocket. For example, when a barcode is read by a scanner 21a such as a barcode scanner, the peripheral device service 31 includes a token received in advance in the request and notifies the POS function service 33 of those events. Next, the peripheral device service 31 transmits a POS function service request for executing a necessary event corresponding to the received peripheral device event to the POS function service 33 (step S92), and ends the process.

Further, although not explained in the flow chart, in the same way of thinking, the POS function service 33 has an asynchronous device event or synchronization from the external input / output device 22, for example, when an operation of changing the cooking state is performed by the kitchen display 22c. Can receive device events that have been made. In that case, the POS function service 33 will execute the necessary event according to the received device event. Taking the above operation as an example, the POS function service 33 sends a request to the POS screen input / output service 34 to display that the cooking state has been changed.

Next, the POS system constructed by the arrangement of the first form will be described with reference to FIGS. 17 and 18. First, an example of deploying to a plurality of stores in one tenant will be described. FIG. 17 is a diagram showing a configuration example in which the POS system 30 of FIG. 6 is used in the arrangement of the first form and deployed in a plurality of stores.

As shown in FIG. 17, the POS system 30 has one or a plurality of POS terminal devices 40-1, 40-2, ... In each of a plurality of stores exemplified by the stores A, B, C, .... They can be arranged and connected to the cloud server 60 for configuration. The above-mentioned store can be a restaurant, but is not limited to this. Further, the POS system 30 can include a handy terminal 22a, a kitchen printer 22b, a kitchen display 22c, and a self-order terminal 22d as external input / output devices 22 in each store.

The cloud server 60 is an example of the cloud server 24 of FIG. 3, and includes a POS function service 33, an authentication service 35, and a DB 32. Here, the restaurant is described as an example, and the POS function service 33 functions as an OES (Order Entry System). Although the DB 32 is provided so as to be accessible from the POS function service 33, it may be provided so as to be directly accessible from the authentication service 35, and the access authority may be determined according to the information contained in the DB 32. The cloud server 60 is composed of a computer, and the CPU can execute a program to perform its function. Of course, the cloud server 60 can also be constructed as a cloud system distributed among a plurality of servers.

The cloud server 60 is physically separated from the store A and is connected via a network. Each POS terminal device 40-1, 40-2, etc. is also connected to the POS function service 33 via a network. Further, the external input / output device 22 is connected to the POS function service 33 of the cloud server 60 via a network.

The POS terminal device (POS # 1) 40-1 includes a peripheral device service 31, and peripheral devices 21a to 21e connected to the device main body can be controlled. Further, the POS terminal device 40-1 can include a POS screen input / output service 34 and a touch panel unit 20 (not shown) which is the target hardware thereof. The POS screen input / output service 34 and the peripheral device service 31 are connected to the POS function service 33 of the cloud server 60 via a network. The POS terminal device 40-1 is configured to include hardware dedicated to POS.

On the other hand, the POS terminal device (POS # 2) 40-2 includes a simple general-purpose PC (simple PC) 40a, a tablet 40b, and peripheral devices 21a to 21e. The simple PC 40a is a terminal physically different from the tablet 40b, includes a peripheral device service 31, is connected to the peripheral devices 21a to 21e, and controls them. The simple PC 40a is connected to the cloud server 60 via a network, and the tablet 40b is connected to the cloud server 60 via a network including at least a wireless network in the store. The tablet 40b can have a touch panel unit and includes a POS screen input / output service 34.

The POS terminal device 40-2 is a system mainly composed of a simple PC 40a and a tablet 40b, and operates in the same manner as a POS dedicated terminal using a POS screen displayed on the tablet 40b. From the point of view of the clerk, the tablet 40b can be used as a POS mobile terminal.

Further, although only the arrangement in the store A has been mainly described, in addition to being able to be used in a single store, the same configuration as in the store A is constructed in the store B and the store C to access the cloud server 60. It can be expanded by doing so. Further, the DB 32, the POS function service 33, and the authentication service 35 can be provided for each store in the cloud server 60.

An operation example in the store A in the POS system of the configuration example of FIG. 17 will be described. The same applies to stores B, C, etc. The POS terminal devices 40-1, 40-2, etc. operate the POS screen input / output service 34 and the peripheral device service 31, access the cloud server 60 to operate the POS function service 33, and DB 32 and authentication via the POS function service 33. Service 35 can also be operated.

When the POS screen of the touch panel unit 20 or the tablet 40b of the store A is operated, the POS screen input / output service 34 accesses the POS function service 33 via the network, downloads the display content (UI image), and displays the display. When the login operation is accepted by the POS screen input / output service 34, the authentication service 35 is accessed through the POS function service 33. The authentication service 35 accesses the DB 32 in which the account information is stored, and authenticates that the login ID and the password match. As a result, in the POS screen input / output service 34, functions related to POS operation and mentance can be used.

At the time of product input, the product information acquired by the POS function service 33 from the DB 32 and responded to is passed to the POS screen input / output service 34 and displayed on the screen of the touch panel unit 20 or the tablet 40b. Make a choice. At this time, the selected product can be displayed on the customer display 21d from the POS function service 33 via the peripheral device service 31. Further, through the network, the receipt for the selected product can be printed by the kitchen printer 22b, and the cooking start instruction to start cooking the product can be displayed on the kitchen display 22c.

Further, when the accounting operation is accepted by the POS screen input / output service 34, the accounting request is transmitted to the POS function service 33, and the peripheral device 21 operates via the peripheral device service 31. Examples of the peripheral device 21 that operates at the time of checkout include a receipt printer 21b, a drawer / change machine 21c, a customer display 21d, and a payment terminal 21e. Further, the contents of the accounting will be stored in the DB 32 through the POS function service 33.

The handy terminal 22a and the self-order terminal 22d are terminals that substitute for operations such as product input performed by the touch panel unit 20 or the tablet 40b, and by transmitting product input and accounting operations to the POS function service 33, product input processing is performed. And to execute accounting processing.

Next, an example of a cloud system extended to multiple tenants will be described. FIG. 18 is a diagram showing a configuration example in which the POS system 30 of FIG. 6 is used in the arrangement of the first form and deployed in a plurality of tenants each having a plurality of stores.

Connected via. Further, in FIG. 18, the stores A, B, ... Belonging to the tenant X and the stores C, D, ... Belonging to the tenant Y exemplify each store. As described above, in the configuration example of FIG. 18, in addition to configuring a plurality of stores, a configuration considering tenants is adopted, and tenant X and tenant Y can point to different management forms, but for example, they are different. It can also refer to the place of residence (another building). The cloud server 60XY can also be constructed as a cloud system distributed among a plurality of servers.

Even in this configuration example in consideration of the tenant, the POS system 30 can be realized by arranging the DB, the POS function service, and the authentication service 35 in the cloud server 60XY. In this example, the POS function services 33X and 33Y corresponding to the tenants X and Y are provided as the POS function services 33, and the DB 32X and 32Y corresponding to each of the tenants X and Y are provided as the DB 32. Further, the authentication service 35 can be directly connected to the DB 32X and 32Y. As for the authentication service 35, an example shared by tenants X and Y is given, but this may also be provided separately for each tenant. Further, the DB, the POS function service, and the authentication service are not limited to the example provided for each tenant in the cloud server 60XY, but can be provided for each store.

Further, although not shown, as in the example of FIG. 17, in each store, a handy terminal 22a, a kitchen printer 22b, a kitchen display 22c, and a self-order terminal 22d may be installed as external input / output devices 22. can.

The POS terminal device 40-1 can adopt the same configuration as the POS terminal device 40-1 of FIG. 17, but here, an example in which a DB 32 is also provided for information multiplexing is given. In the configuration in which the DB 32 is multiplexed, the DB 32 can be added to the POS terminal device 40-1 or the like and operated in this way, and a cluster configuration or a replication configuration can be realized together with the DB 32 in the edge server 50 described later. The POS terminal devices 40-2 and 40-3 have the same configuration as the POS terminal devices 40-1 and 40-2 of FIG. 17, respectively. The tablet 40b in the POS terminal device 40-3 is wirelessly connected to the edge server 50, and includes a POS screen input / output service 34 wirelessly connected to the POS function service 33 in the edge server 50.

However, in the POS terminal devices 40-1, 40-2, 40-3 of FIG. 19, the POS function service 33 is connected to any of the POS screen input / output services 34, but the POS function service 33 is an edge. It is provided in the server 50. Although wiring is not shown in FIG. 19 for convenience, it is assumed that the peripheral device service 31 in each device is connected to the POS function service 33 of the edge server 50.

The edge server 50 is an example of the local server 25 in FIG. 4, and includes a POS function service 33, an authentication service 35, and a DB 32, which are connected to each other. The edge server 50 can also be referred to as a local server device (local server), is configured by a computer, and can fulfill its function by the CPU executing a program. Of course, the edge server 50 can also be constructed as a system distributed among a plurality of servers.

In the tablet 40b, the POS screen input / output service 34 is operated by using the browser mounted on the tablet 40b, and is connected to the POS function service 33 of the edge server 50 to realize the input / output function to the POS screen. The operations of authentication, product input, and accounting in each POS terminal device are basically the same as those of FIG. 17, except that the destination of information is mainly different.

Next, the POS system constructed by the arrangement of the third form will be described with reference to FIG. FIG. 20 is a diagram showing a configuration example in which the POS system 30 of FIG. 6 is used in the arrangement of the third form.

As shown in FIG. 20, the POS system 30 can be configured by simply arranging one or a plurality of POS terminal devices 40-1, 40-2, 40-3, ... In one store. The POS terminal device 40-1 includes a peripheral device service 31, a DB 32, a POS function service 33, a POS screen input / output service 34, and an authentication service 35. The peripheral device service 31, DB 32, the POS screen input / output service 34, and the authentication service 35 are all connected to at least the POS function service 33, and the authentication service 35 can also be directly connected to the DB 32 as shown in the figure. ..

The POS terminal device 40-2 includes a peripheral device service 31, a DB 32, a POS function service 33, a POS screen input / output service 34, and an authentication service 35. The peripheral device service 31, DB 32, the POS screen input / output service 34, and the authentication service 35 are all connected to at least the POS function service 33, and the authentication service 35, which is not shown, can be directly connected to the DB 32.

Here, the DB 32 provided in the POS terminal device 40-2 may be configured to be referred to when operating in the POS terminal device 40-2, but the POS terminal device 40-1 may be duplicated with the DB 32. Can only be used for. In the former case, the operation in the POS terminal device 40-2 is the same as the operation in the POS terminal device 40-1. In the latter case, the POS function service 33 (and the authentication service 35) in the POS terminal device 40-2 accesses and operates the DB 32 in the POS terminal device 40-1.

The POS terminal device 40-3 includes a peripheral device service 31, a POS function service 33, a POS screen input / output service 34, and an authentication service 35, and the POS function service 33 and the authentication service 35 are connected to the DB 32 in the POS terminal device 40-1. It is connected. The peripheral device service 31, the POS screen input / output service 34, and the authentication service 35 are all connected to at least the POS function service 33.

The POS terminal device 40-4 includes a simple PC 40a, a tablet 40b, and peripheral devices 21a to 21e, similarly to the POS terminal device 40-2 of FIG. The simple PC 40a is provided with a peripheral device service 31, and the tablet 40b is provided with a POS screen input / output service 34 wirelessly connected to the POS function service 33 of the POS terminal device 40-1.

Further, in the store, as an external input / output device 22, a handy terminal 22a, a kitchen printer 22b, a kitchen display 22c, and a self-order terminal 22d are installed by connecting to the POS function service 33 of the POS terminal device 40-1. Can be kept. Although not shown in FIG. 20, each external input / output device 22 is connected to the POS function service 33 for the POS terminal devices 40-2, 40-3, and 40-4 as well as the POS terminal device 40-1. Has been done.

As described above, in the POS system of FIG. 20, basically, they are individually operated inside the dedicated POS terminal device, but the DB 32 is operated by at least one POS terminal device 40-1, and other POS terminal devices are operated. The DB 32 provided in the above can be used for duplication. The POS function service 33 of all POS terminal devices 40-1, 40-2, 40-3, ... Accesses the primary DB 32 in the store (here, DB 32 of POS terminal device 40-1). Operate. The operations of authentication, product input, and accounting in each of the other POS terminal devices are basically the same as those of FIG. 17, except that the destination of information is mainly different.

As described above, in the present embodiment, by dividing the functional services related to the POS system, the restrictions on the physical arrangement are minimized, and the configuration (functional services) is configured without changing the contents of the functional services. Arrangement) can be changed. The reason is that at least the functional services that people come into contact with can perform functions by physically arranging them in the store separately from other functional services, and the above other functional services do not depend on the physical arrangement. , To be able to perform the function.

Therefore, in the present embodiment, for example, not only the construction of a closed POS system (the second or third form of the POS system) in one store such as one restaurant, but also the construction of the POS by the cloud system is performed. It is also possible to do this without changing the content of the functional service. As a result, the same functional service can be used regardless of whether the system is closed in one store or a cloud system, so that the development cost can be reduced.

Further, the DB such as the DB 32 is centrally managed as described above, but by adopting a multiplexed configuration as partially exemplified, for example, it is possible to suppress the suspension of business during the opening of the store. Can be done. Further, by multiplexing the DB, it is possible to improve the security of data in each form of a single store, a form using a store and an edge server, and a form using a cloud.
