Description

  The present invention relates to a system that allows easy confirmation of a sales situation at an article sales store, and more particularly, to a shortage prevention system at a store that can prevent a shortage at a direct sales place in a production area.

  In a conventional shortage prevention system in a store, for example, a producer who is a supplier of agricultural products or the like at a direct sales place in the production area grasps how much his / her deliverables are sold. For this reason, it was common for producers to go to the direct sales office for confirmation, so there were few opportunities for confirmation, so sales opportunities were often missed, and sales could not be promoted.

  In order to solve such a problem, for example, Japanese Patent Laid-Open No. 2001-306887 (Patent Document 1) discloses a “business model for obtaining sales information” using a mobile phone that has recently become extremely popular.

  This will be described with reference to FIG. The mobile phone 70 uses the public communication network 140 by using “i-mode (registered trademark)” of a telephone company, for example, NTT Docomo Group, and stores sales from the POS (Point Of Sales) register 110 of each store. I have information.

  However, in this system, first, since the following functions are required for the POS register, complication of the POS register is inevitable. That is, the POS register needs a function of editing a sales information Web page to be displayed on a mobile phone via a public communication network and transmitting data corresponding to a caller address in response to a request from the mobile phone. Furthermore, when there are a plurality of POS registers in the same store, a server that collects and transmits information from each POS register is assumed.

  Separately, for example, in Japanese Patent Application Laid-Open No. 2003-087419 (Patent Document 2), there is a “sales management support system” in which sales results are taken in via a public communication network and the Internet, and summed up by a portable wireless terminal device. It is disclosed.

  This will be described with reference to FIG. That is, the sales management center 130 collects information related to sales management such as sales results directly from the POS register 110 or via the Internet 140. Then, the sales management center 130 distributes the collected data to, for example, the fixed telephone device 160 owned by the producer periodically, for example. The fixed telephone device 160 aggregates the sales results received from the sales management center 130. The user calls the fixed telephone device 160 from a portable wireless terminal device 170 in the vicinity, for example, at home or on the premises, and receives and analyzes the sales results that have been tabulated.

  In Patent Document 1, as described above, since a mobile phone calls a single POS register to acquire a sales record, data editing and a distribution function for facilitating reading with the mobile phone are required. . On the other hand, when there are a plurality of sales bases, the mobile phone needs an editing function such as counting a plurality of pieces of acquired information. Therefore, an additional function is necessary for the conventional function.

  Moreover, in patent document 2, a user can receive the sales performance of each sales base collectively in a fixed telephone apparatus. However, data can be acquired on the premises such as in a factory, for example, when the user is a producer by a factory, but when the direct sales place such as agricultural products is used as a sales base for agriculture, the user's work place is a store. However, it is desired to use a mobile phone using a public communication network.

JP 2001-306887 A JP 2003-087419 A

  The problem to be solved is that the sales results obtained from a plurality of POS registers cannot be easily obtained by a mobile phone connected to the public communication network, and therefore it is not possible to prevent the occurrence of a shortage at a sales store. .

  The present invention collects sales information including sales results from each POS register for the purpose of easily obtaining a total of sales results obtained from a plurality of POS registers with a mobile phone connected to a public communication network. A server, and an information management distribution server that acquires the collected information from the information collection server and edits and holds the screen display registration information that can be referred to at least by a mobile phone or a portable communication terminal and a PC. Features.

  That is, the information management distribution server has registration information mail creation / transmission means for creating the screen display registration information in the body of or attached to the transmission mail and transmitting the transmission mail to a predetermined destination at a predetermined time. With such a configuration, the information management distribution server can send each registration information held by itself to a predetermined destination at a predetermined time, so that the user can set a location at a desired time by using a mobile phone. Any desired sales information can be received.

  This information management distribution server edits the screen display registration information into a web page so that it can be viewed from a mobile phone, PC, etc. via a communication network, and sets a predetermined address such as a URL (Uniform Resource Locator). It is desirable to give and register. With this configuration, the user terminal can specify a predetermined address such as a URL, call a desired web page, display it, and browse it.

  For this reason, the information management distribution server has address mail creation / transmission means for creating the address included in the body of the sent mail and sending it to a predetermined destination at a predetermined time, or receiving a call request from the user terminal using the address In some cases, it is desirable to have a registration information transmitting means for identifying the requesting user and transmitting a web page corresponding to the user.

  The shortage prevention system in the store of the present invention is a web page or an outgoing mail so that a server connected to a communication network including the Internet can view sales information collected from a POS register from a mobile phone, a PC or the like. Edited at a predetermined time and transmitted to a predetermined destination. On the other hand, the information management / distribution server assigns a predetermined URL or e-mail address to the sales information edited on the web page, and the information edited on the web page can be called from a mobile phone, a PC, or the like. Therefore, since the producer who needs sales information can grasp the sales performance anytime and anywhere, there is an advantage that the shortage at the sales store can be prevented.

  A server connected to a communication network such as the Internet can collect sales results at a sales store and view it on at least a portable communication terminal such as a mobile phone, with the aim of preventing shortages at the store. It was solved by editing and holding as registration information. That is, by registering sales information, it is possible to realize that the user can obtain sales information including desired sales results at any time and anywhere without impairing the normal functions of the POS register and the mobile phone.

  The present invention will be described below with reference to the drawings. In the drawings, portions according to the present invention are shown as seeds, and some components that are indispensable as a system are omitted from the drawings for the convenience of the size of the drawings.

  A first embodiment of the present invention will be described with reference to FIG.

  FIG. 1 is an explanatory diagram showing in block form an embodiment of the sales information notification function in the shortage prevention system according to the present invention.

  The system includes a POS register 11, 12 provided in the store 10, a LAN (Local Area Network) 20, a store server 31 and an information organizing PC (Personal Computer) 32 provided in the information collection server 30, the Internet 40, and an information management distribution server 50. And a user terminal 60. The information management distribution server 50 has a registration information memory 51, and the user terminal 60 includes user PCs 61 and 62 and mobile phones 71 and 72.

  The store 10 includes a direct sales place in an agricultural area, and the same store and the same premises are assumed. Further, it is assumed that the information collection server 30 connected to the LAN 20 together with the LAN 20 belongs to the same store 10. Of course, the structure by this invention is one Embodiment, It is not limited to the structure shown in figure.

  At least one POS register 11, 12 is provided in each store 10, and is connected to the LAN 20 in the same store 10. Sales information is input to the POS registers 11 and 12 by a salesperson at each sale, and the input sales information is stored therein and immediately sent to the information collection server 30 via the LAN 20. Needless to say, the POS registers 11 and 12 may send the sales information to the information collection server 30 in a batch or in a predetermined range at regular or predetermined times.

  In sales information, the user is the producer, and the producer code (numeric value), producer name (character string), department code (numeric value), department name (character string), product code (numeric value), product name (character string) ), Sales quantity (numeric value), sales amount (numeric value), sales date (character string), total sales quantity (numeric value), sales time (character string), and the like.

  The LAN 20 is connected to the POS registers 11 and 12 and the information collection server 30 in the store 10 on the same premises and used for mutual data communication, and is connected to the Internet 40.

  The information collection server 30 is provided for each store 10, collects the sales information for each store 10, and accesses the Internet 40 via the LAN 20. In this embodiment, the information collecting server 30 includes a store server 31 and an information organizing PC 32.

  The store server 31 receives sales information immediately from the POS registers 11 and 12 via the LAN 20 when sales occur, and collects them in a predetermined format for each store 10, for example. The collected sales information is used for sales activities in the store 10, for example. The store server 31 may receive sales information from the POS registers 11 and 12 periodically or at a predetermined time in a batch or in a predetermined range.

  The information organizing PC 32 directly receives the sales information collected by the store server 31 periodically every 30 minutes, and aggregates the information from the LAN 20 via the Internet 40 for the producer, for example, every producer, every sales time. It is sent to the management distribution server 50. The information organizing PC 32 includes a display and an operation panel, and can input and output information by an operator operation for sales management.

  Further, the information organizing PC 32 can directly receive the sales information from the POS registers 11 and 12 when the store server 31 cannot receive the sales information within a predetermined time due to a failure or lack of function. Therefore, the information organizing PC 32 has a sales information collecting function similar to that of the store server 31.

  Although the information transfer request between the store server 31 and the information organizing PC 32 has been described as being from the store server 31, it may be requested periodically from the information organizing PC 32. Can be determined.

  The Internet 40 includes a public communication network for “i-mode” (registered trademark) of a mobile phone, for example, and is connected to the LAN 20, the information management distribution server 50, and the user terminal 60.

  The information management distribution server 50 receives the sales information from the information organizing PC 32, edits it into a Web page so that it can be viewed on the mobile phones 71 and 72 as well as the user PCs 61 and 62, and uses it as registered information. The web page is recorded in the registration information memory 51, and in the case of transmission as a mail, it is created as a transmission mail by a mailer.

  Here, the information management distribution server 50 will be described with reference to FIG.

  The information management distribution server 50 includes a registration information memory 51, an edit registration unit 52, an address mail creation / transmission unit 53, a registration information transmission unit 54, and a registration information mail creation / transmission unit 55.

  In the registration information memory 51, web pages are recorded as registration information. The edit registration means 52 edits the sales information received from the information collection server 30 into a web page so that it can be viewed on a mobile phone. For example, the web page is edited by a producer code included in the received sales information, and is associated with the address of the producer. Moreover, it is also possible to edit a web page that covers all information of a direct sales place in the production area, for example, by aggregation not limited to the producer code. For example, a URL (Uniform Resource Locator) is assigned to the web page created in this way as an address.

  The address mail creation / transmission means 53 creates an address by including it in the text of the transmission mail, and transmits it to a predetermined destination at a predetermined time. When receiving a call request from the user terminal 60 with an address such as a URL, the registration information transmitting means 54 identifies the requesting user and reads out and sends out a web page corresponding to the user from the registration information memory 51. The registration information mail creation / transmission means 55 creates the screen display registration information in the body of the transmission mail and transmits the transmission mail to a predetermined destination at a predetermined time. All of these functions can be provided, but they may be used alone.

  That is, since the information management distribution server 50 has a WWW (World Wide Web) server function, the user terminals 60 such as the user PCs 61 and 62 and the mobile phones 71 and 72 are registered in the information management distribution server 50 as registered information. You can refer to the stored sales information. Furthermore, since the information management distribution server 50 has a mail server function, for example, it holds a user code or a producer code and a corresponding user address or a producer address, and responds to a user request by an e-mail. be able to.

  Since such a form is adopted, the user terminal 60 possessed by the user transmits the transmission from the information management distribution server 50 to the user PCs 61 and 62 or the mobile phones 71 and 72 corresponding to the address of the producer who is the user. You can receive it as a received mail. In this case, the predetermined sales information can be received by the mail text or the attached information. In addition, when the sales information is divided into a plurality of items, the received mail includes a URL or an email address for the target sales information, and the desired information can be obtained by clicking a desired item.

  Further, since the above configuration is adopted, the user terminal 60 possessed by the user can send a URL or e-mail to the information management distribution server 50 from the user PC 61 or 62 or the mobile phone 71 or 72 corresponding to the address of the producer who is the user. Sales information edited by address can be received in a predetermined format.

  That is, a user who is a producer can easily obtain sales information such as desired sales results anytime and anywhere by using a mobile phone, for example.

  Further, in the above description, the information collection server 30 is illustrated as being configured by the store server 31 and the information organizing PC 32. However, the information collection server 30 may be configured by a single server having the respective functions.

  Details of the functions for the above-described components will be described below using a flowchart as an example for each of a plurality of operation procedures for obtaining sales information.

  An embodiment of the present invention will be described as Example 2 with reference to FIGS.

  As shown in FIG. 3, the POS register 11 receives an input of the record every time the product is sold in the store 10, for example, the direct sales place (procedure S 1). Accumulate as a file (procedure S2). On the other hand, the POS register 11 sends the received sales record as sales information to the store server 31 via the LAN 20 (step S3). As shown in the figure, the sales record input through the online service is usually sent to the store server 31 immediately. However, for example, it may be a procedure that is periodically sent every 30 minutes or a request from the store server 31 or a procedure including these procedures.

  When the store server 31 receives the sales information from the POS register 11, the store server 31 always integrates and summarizes the current sales information (step S4), and records and updates it in one sales information file based on the integrated predetermined format. (Procedure S5). Further, the store server 31 accepts sales information from POS registers other than the POS register 11, such as the POS register 12, and therefore, similar to the above-described procedure, the collected sales information file is updated every time it is accepted. Provided for every 10 sales activities.

  Then, the store server 31 sends the sales information updated by counting to the information organizing PC 32 periodically (step S6), for example, every 30 minutes.

  The process so far is a general sales aggregation process using a POS register. In the above description, the sales information file is counted when the store server 31 receives the sales information from the POS register, and the sales information file is updated by this. However, the procedure and configuration may be such that the sales information received from the POS register is temporarily stored, and the sales information is aggregated when the sales information is sent to the information organizing PC 32 to create a sales information file.

  As described above, this sales information file includes, for example, a producer code (numerical value), a producer name (character string), a department code (numeric value), a department name (character string), a product code (numeric value), a product name ( Character string), sales quantity (numeric value), sales amount (numeric value), sales date (character string), total sales quantity (numeric value), sales time (character string), and the like. Here, the producer is a delivery person who has delivered the product to the direct sales place.

  When the sales information file is acquired from the store server 31 (step S7), the information organizing PC 32 extracts predetermined information from the sales information file and edits it into a text file in CSV (Comma Separated Values) format (step S8). The information is transmitted to the information management distribution server 50 (step S9).

  In the procedure S6, the store server 31 periodically sends sales information to the information organizing PC 32. However, the information organizing PC 32 may periodically send a sales information request (procedure S10). That is, the store server 31 may send sales information when receiving a sales information request sent at a predetermined time, such as periodically, from the information organizing PC 32 in the procedure S6. In any case, in this embodiment, the sales information is transmitted every 30 minutes.

  As shown in FIG. 4, when the information management distribution server 50 receives the sales information file edited into a text file from the information organizing PC 32 (step S11), the sales information for each producer is extracted from the file (procedure). S12). The information management distribution server 50 edits the extracted information into a format that can be referred to by the web (Web) reference function of the user terminal 60 by the edit registration means 52, and dynamically assigns an address to the edited information. Register with the activated WWW service (step S13). As a format that can be referred to by the web reference function, there is, for example, CHTML (Compact HTML) being standardized by the standardization organization W3C (WWW Consortium).

  Furthermore, the information management distribution server 50 further aggregates the sales information of the entire production place direct sales place, not by producer (step S14), and edits it into a format that can be referred to by the web reference function of the user terminal 60. An address, such as a URL, is dynamically assigned to the edited information and registered as registration information in the active WWW service (step S15). Information given the registered address is recorded in the registration information memory 51 as a web page.

  Since the information management distribution server 50 further includes mail server functions such as address mail creation / transmission means 53 and registration information mail creation / transmission means 55, for example, a user code or a producer code and a corresponding user address or production A person's address, and can respond to the user's request by e-mail.

  That is, when the information management distribution server 50 edits and registers the sales information by producer and the overall sales information not by producer in a format that can be viewed from a mobile phone or the like by the edit registration means 52 in step S15. Then, an e-mail is created, edited and transmitted to each producer registered in advance by the address mail creating / transmitting means 53 (step S16). Each e-mail includes a web page address for each producer and a web page address for sales information directly from the production center, and can be received by the producer's user PC 61 or 62 or mobile phone 71 or 72 by e-mail.

  In the present embodiment, the sales information is periodically acquired by the information organizing PC 32 every 30 minutes according to the procedure S6 or S10, and after the editing process, it is immediately transferred to the information management distribution server 50 for registration processing. Sent by e-mail. Accordingly, the electronic mail is periodically transmitted to the user terminal 60 approximately every 30 minutes.

  The editing process in the mail server and the mail transmission / reception process between the mail server and the user terminal are automatically performed. In this embodiment, Perl (Practical Extraction and Report Language) and PHP (Hypertext Preprocessor) are script languages. It is supposed to work with.

  For example, the cellular phone 71 of the producer receives an e-mail having the web page address of the sales information file from the information management distribution server 50 from the information management distribution server 50 in this embodiment at intervals of approximately 30 minutes (step S17). Can do.

  Each e-mail includes a web page address for each producer and a web page address for the sales information directly from the production center. In step S17, the user PCs 61 and 62 or the mobile phones 71 and 72 send e-mails. Can be accessed, for example, by clicking on the described URL to access the desired information (step S18). When the mobile phone 71 accesses the URL, the information management distribution server 50 that holds the web page corresponding to the URL accepts the call request, and the registration information transmitted to the designated web page by the registration information transmitting unit 54. Is read from the registration information memory 51 and sent to the requesting mobile phone 71 (step S19).

  The producer displays the registration information on the screen of the mobile phone 71 that requested the call (step S20) and can refer to it as a web page. Therefore, the sales information of the products delivered by the respective producers at that time and necessary Thus, it is possible to know the sales information of the entire production area direct sales office. In the user terminal 60, for example, when the mobile phones 71 and 72 are of different producers, the information management distribution server 50 transmits mails including different web page addresses corresponding to the producers. .

  In the case of the present embodiment, since the mail is transmitted at intervals of 30 minutes, the producer can know the sales information at intervals of 30 minutes. As described above, this timing is not limited to a regular period of 30 minutes, and can be set according to an arbitrarily determined time or condition.

  In the above description, the user terminal is a mobile phone, but the same applies to a PC.

  Since such a form is adopted, the user terminal possessed by the user can receive, for example, periodically the address on the web of the sales information, for example, the URL by the received mail. The received mail is edited in a predetermined format from the information management distribution server to the user PC or mobile phone of the producer who is the user.

  Therefore, desired sales information can be easily acquired by a simple procedure by clicking the URL in the mail text.

  An embodiment of the present invention will be described as Example 3 with reference to FIGS.

  In the third embodiment, the information management distribution server 50 uses the registration information mail creation / transmission means 55 to create the web page text in the mail text instead of entering the URL of the web page address in the mail text in step S16 in FIG. Alternatively, it is a method of attaching the web page text to the mail and sending it to the request source on time (step S31).

  In this case, the requesting mobile phone 71 receives the predetermined registration information on the web page by e-mail with the mail text or attached information (step S32), so that the received registration information can be immediately displayed on the screen (step S33).

  In the above description, the mobile phone is used, but the same applies to the user PC.

  Since such a form is adopted, desired registration information can be immediately selected and browsed. Therefore, information can be collected more quickly than in the second embodiment.

  One embodiment of the present invention will be described as a fourth embodiment with reference to FIGS.

  The third embodiment is a method for calling, from the user terminal 60, the information for each producer and the sales information for the entire production area direct sales office collected and registered in the information management distribution server 50 of FIG.

  In step S15 in FIG. 4, the sales information for each producer and the entire sales place of the production center are edited into a format that can be referred to by the web reference function of the user terminal 60, and an address is dynamically assigned to the edited information. be registered. Since the user knows the web address of the registration information to be registered, the registered sales information can be called up by accessing the Internet from the user PC 61 using the web address corresponding to the desired information, for example, the URL. Is requested to the information management distribution server 50 (step S41).

  Receiving the request, the information management distribution server 50 reads the web information corresponding to the URL by the registered information transmission means 54 and sends it to the requesting user PC 61 (step S42). Since the user PC 61 accepts predetermined registration information in the web page, the received information can be displayed on the screen (step S43).

  In the above description, the user PC is used, but the same applies to a mobile phone.

  Since such a form is adopted, desired information can be selected and browsed when the user desires. Therefore, as compared with the second embodiment, information can be collected at an arbitrarily set appropriate time.

  According to the present invention, an information collection server that collects sales information including sales results from each POS register, and the collected information is acquired from the information collection server, edited for screen display that can be referred to by a mobile phone, and held as registration information. By using the information management distribution server, the sales information of the store can be easily and easily notified by e-mail even on a user terminal such as a mobile phone, and can be called by a request from the user side. Therefore, the present invention can be applied to the use of notifying each of a plurality of users and the entire collected information for each user with a simple configuration.
