Thus, the commodity is provided to a customer in a short time by easily and highly reliably detecting the duplicate data with the use of the multiple collation items while generating the sequence number by order reception entry for every small-number of commodity, so as to generate the transmission data. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to an electronic information processing system that prepares a product by sending ordered product information to a cooking place via a communication path from a register system that accepts an order from a customer. In particular, authentication of transmission data related to ordered product information is reliable. The present invention relates to a method for transmitting and receiving kitchen display data and a system using the method.

  As a conventional kitchen display data transmission / reception system using a data communication path, for example, there is an electronic register disclosed in Japanese Patent Laid-Open No. 9-35147 (Patent Document 1).

  In this electronic register, the order merchandise information registered for each item registration at the register terminal is sequentially transmitted to the kitchen video controller via the data communication path and displayed on the display device. When the order delete key is operated in the cooking chamber, the screen display of the product is deleted as soon as preparation of the ordered product is completed.

  In this way, the data communication path is used to transmit the order merchandise information from the register terminal to the kitchen video controller. However, since many types of data are mixed even in the LAN, the data communication path depends on the state of the communication network. Omission and duplication are inevitable.

  As an improvement measure, there is a general-purpose technique in which an acknowledgment is returned in response to transmitted data and the same data is retransmitted when a reception error occurs. However, in this technique, since the returned confirmation response has not arrived at the transmission source, the transmission side retransmits, so there is a possibility that the reception side will receive duplicates.

  As this improvement measure, for example, there is a communication method disclosed in Japanese Patent Laid-Open No. 2002-44094 (Patent Document 2). In this communication method, data is transmitted by adding second identification information to the first identification information as duplication determination information, and each time message data having the same first identification information value is transmitted. In addition, different values are simultaneously given to the message data as the second identification information. As a result, the receiving side can determine whether or not duplicate reception is performed depending on whether or not the value of the second identification information is different for each received discrimination information.

  However, in this method, the first or second identification information is identified as identical by a single number or character error, and it is feared that important data may be lost because duplicate reception is determined. Such a situation should be avoided because the lack of ordered products is a problem for customers. On the other hand, duplicate reception of data is a burden on the store side, but it can be detected to some extent by checking a number of collation items in the transmission data common part.

JP 9-35147 A JP 2002-44094 A

  The problem to be solved is caused by the status of the communication path, when only the two items of information are collated when the order product information is sent from the register system that accepts the order to the kitchen via the communication path to prepare the product. In this case, the identification of the duplicated reception is incomplete, and there is a risk that the customer may be missing the ordered product.

  An object of the present invention is to improve the certainty of detection of duplicate received data when order data is transmitted via a communication path.

  Therefore, in the transmission of kitchen display data according to the present invention, the common part of the transmission data includes three or more of the items including the customer number, order number, sequence number, and registration time (transmission entry time) as matching items. On the receiving side, the main feature is that duplicate received data is determined by all matches of the matching items. As described above, since a large number of collation items are provided, the certainty of determination on duplicate received data is improved. In particular, by adding time information different from the sequence number as fixed information, it is possible to more reliably determine duplicate received data.

  As a system that embodies this, there are a register system that transmits order data by the above-described method and a kitchen display that accepts the transmitted data by the above-described method.

  The time of the transmission entry is preferably fixed to the time of the first transmission entry. Furthermore, the register system can generate a transmission entry for each product for data transmission. As a result, the order product information can be immediately transmitted to the kitchen display at the time of order acceptance, so that the order acceptance product can be provided to the customer in a short time.

  Since the kitchen display data transmission / reception method of the present invention and the system using the method have three or more collation items in the common part of the transmission data, in particular, time information that is not just a sequence number is used as the collation item. In addition, since more reliable duplicate received data can be determined, there is an advantage that it is possible to avoid the inconvenience of causing the customer to lose the ordered product because the duplicate received data is erroneously determined.

  The present invention is intended for the food service industry such as fast food, restaurants, etc., and when sending order data received by a register system to a kitchen display of a kitchen via a communication channel, duplicate transmission determination for the same data is performed. The goal is to improve certainty. Therefore, on the transmission side, three or more collation items among items including the customer number, the order number, the sequence number, and the registration time by the transmission entry are included in the common part of the transmission data and transmitted. On the other hand, on the receiving side, duplicate received data is determined based on all matches of the matching items.

  Hereinafter, embodiments will be described with reference to the drawings. However, since the paper and the description are mainly related to the present invention, some essential functions are omitted from the constituent elements. In addition, the functional blocks can be merged and separated, and the flowcharts can be changed before and after the procedure, as long as they do not impair the purpose and description of the present invention, and this description does not limit the present invention. Absent.

  First, the system configuration of the present invention will be described with reference to FIG.

  FIG. 1 is a block diagram illustrating an embodiment of a kitchen display data transmission / reception system according to the present invention.

  As shown in the figure, a register system 1 is connected to the data transmission side, and a kitchen display 2 is connected to the reception side via a data communication path 3. The register system 1 includes an input unit 11, a calculation control unit 12, a storage unit 13, an output unit 14, a data transmission unit 15, and a clock unit 16. The kitchen display 2 includes a data receiving unit 21, a calculation control unit 22, a storage unit 23, a product notification unit 24, and an input unit 25. In the data communication path 3, transmission data 31 is sent from the transmission side to the reception side, and a response message 32 corresponding to the transmission data 31 is returned in the opposite direction.

  The register system 1 is a POS (point-of-sale management) system including a register device that, when an order is received from a customer, generates order information in an order slip, notifies the kitchen, calculates a total amount, and issues a receipt. . Accordingly, the input unit 11 is a portable terminal that receives an order from a customer and inputs it, and a keyboard, a button, and the like such as an accounting machine that counts input product information and issues a receipt, and is connected to the calculation control unit 12. The arithmetic control unit 12 is a processor that is program-controlled by being connected to the storage unit 13, and is further connected to all the components in the register system 1 to execute the function of the register system 1. Details of the present invention will be described later. The storage unit 13 mainly stores the order merchandise information registered by the order from the input unit 11 together with various items including the order number. Under the control of the arithmetic control unit 12, the stored data is visible and audible in the output unit 14. On the other hand, it is sent to the data transmitter 15. The output unit 14 is, for example, a screen display device, a visible display device such as a printer, and an audible display device such as a buzzer or a speaker. Under the control of the arithmetic control unit 12, the data transmission unit 15 forms transmission data recorded in the storage unit 13 in a predetermined format and sends it to the data communication path 3.

  The kitchen display 2 is a device for displaying the ordered products provided in the kitchen, and the cook prepares the ingredients from the product names displayed on the screen and provides them as products. When the data receiving unit 21 receives the transmission data 31 via the data communication path 32, the data receiving unit 21 receives control from the arithmetic control unit 22 and discards the received data or records it in the storage unit 23. The arithmetic control unit 22 is a processor that is connected to the storage unit 23 and is program-controlled, and further connected to all the components in the kitchen display 2 to execute the function of the kitchen display 2. Details will be described later. The storage unit 23 mainly stores the order product information received from the data receiving unit 21, and the stored data is visually output to the product notification unit 24 by the control of the calculation control unit 22. Under the control of the calculation control unit 22, the product notification unit 24 causes the data receiving unit 21 to sound a predetermined notification sound when receiving the transmission data of the received order product, and the received order data recorded in the storage unit 23 is stored in the predetermined order. While the screen is displayed in a format, the screen display is changed, added, or deleted based on an instruction from the input unit 25. The input unit 25 is, for example, an apparatus integrated with the product notification unit 24, and enables screen switching, preparation start product designation, display unnecessary screen blanking, and the like by user operation of keys or buttons.

  The data communication path 3 may be a directly connected line, but a normal information processing network is applied as a recent communication network. Therefore, many kinds of large amounts of data are flying over the communication path. For this reason, code loss and conversion are likely to occur, and retransmission of transmission data is frequent. Therefore, in the transmission data 31, the customer number, the order number, the sequence number, and the registration time are included in the common part as collation items on the receiving side. The product part includes the name of the product for which the order has been received, together with the quantity, as product information. The response message 32 is returned to the register system 1 including the normal / abnormal report of the reception result when receiving the transmission data 31 on the kitchen display 2. When an abnormality is reported, the transmission data is retransmitted according to the situation, and the transmission data is also retransmitted when the response message does not reach the transmission side.

  The customer number of the verification item can be generated from, for example, a number including a table number when a group is formed on the order and, for example, the first acceptance time when there are a plurality of sets in one table. The order number is given when an order for a product is received. For example, if there is an additional order later, the order number is sequentially changed with the same customer number. The order number is sequentially given to the same customer number and order number, for example, when order entries are sequentially registered even while orders are being received. As a result, the registered product can be immediately notified to the kitchen by entry registration. The registration time is, for example, the date and time when the entry button is operated on the portable terminal that received the order. At this time, the product information of the new order registration is sent from the register system 1 to the kitchen display 2 via the data communication path 3. Sent. These collation items may be further increased by adding another item, but it is not necessary to collate all of them. In the case of a large number of collation items, not only duplicate data can be detected, but also non-duplicate data can be corrected abnormally.

  Next, the main operation procedure for order entry in the register system 1 will be described with reference to FIG.

  When the table number is input from the input unit 11 of the portable terminal as an order start by the store clerk, the calculation control unit 12 accepts this (step S1) and is the first order (NO in step S2). A customer number is generated from the table number and time and recorded in the storage unit 13 (step S3). When there is an input of the first order product (YES in step S4), the arithmetic control unit 12 generates the first order number / order number and records the product information of the product name and quantity of the ordered product in the storage unit 13 ( Step S5). Subsequently, when there is no entry entry for registration (NO in step S6) and the product name and quantity of the next ordered product are entered (YES in step S7), product information is added with the same order number / order number. Recording is performed (procedure S8), and the procedure returns to the entry receiving procedure of the procedure S6. In this way, successive additional orders are entered together.

  When the above step S6 is “YES” and a registration entry is input, the arithmetic control unit 12 encodes the time of the current time into the registered customer time, order number, and sequence number in the storage unit 13 into the registration time. Are recorded in the common part as items to be collated, and the product information continuously input is formed in the product part and sent from the storage unit 13 to the data transmission unit 15 to create transmission data 31. Then, the data is transmitted to the data communication path 3 (step S11).

  If there is no subsequent order (NO in step S12), the procedure is terminated as it is. However, if step S12 is “YES” and there is an order, the operation control unit 13 generates the next sequence number and the product. Product information is newly recorded (step S13), and the procedure returns to step S6.

  Further, when the above step S2 is “NO” and the customer has an additional order, the customer number is searched from the table number (step S14), the next order number and the order number are generated, and this product information is stored. The data is recorded in the unit 13 (procedure S15), and the procedure proceeds to the procedure S6.

  By such a procedure, not only can the number of collation items be increased, but also by the entry operation for each product, the product information can be immediately transmitted to the kitchen by accepting the ordered product and can be notified on the kitchen screen. Therefore, it is possible to provide the ordered product to the customer at an early stage by starting the preparation of the product and shortening the time until the completion.

  Next, data transmission of the register system 1 will be described with reference to FIGS. 1 and 2 together with FIG.

  When the entry input is accepted in “YES” in the step S6 and the transmission data 31 including the collation item in the step S11 is transmitted to the data communication path 3, the arithmetic control unit 12 sets a monitoring timer (not shown). Measurement is started (step S21). If the response message of normal reception is received before the timer time limit is reached (NO in step S22) (YES in step S23), the arithmetic control unit 12 determines whether or not the response message is normally received (step S24). ) If this step S24 is “YES” and normal reception is performed, the collation item of the response message is confirmed (step S25), the recorded data is confirmed for accounting, and the monitoring timer is initialized to prepare for the next entry input acceptance. (Procedure S26) and the procedure ends.

  When the above-described step S22 is “YES” and the timer time limit has been reached, the arithmetic control unit 12 initializes the monitoring timer and retransmits the transmission data 31 having the same contents as previously transmitted from the data transmission unit 15 (step S27). Then, the process returns to step S21. When the above step S24 is “NO” and the response message is a retransmission request, the arithmetic control unit 12 accepts the message (step S28), initializes the monitoring timer, and transmits the transmission data 31 having the same contents as the previous transmission. Is retransmitted from the data transmitter 15 (step S29), and the process returns to step S21.

  The above procedure is well known and has no features according to the present invention. However, since there are a large number of collation items in the transmission data, collating the collation items in addition to the response message format is effective for various data confirmation.

  Next, the main operation procedure of the kitchen display 2 will be described with reference to FIGS. 1 to 3 in FIG.

  First, when the data receiving unit 21 receives the transmission data 31 from the data communication path 3 (procedure S31), the arithmetic control unit 22 sets a predetermined item of the common part between the received transmission data 31 and the already recorded transmission data. Collation is performed (procedure S32). In the case of collation coincidence (YES in step S33), for example, since duplicate data is detected by retransmission, the arithmetic control unit 22 discards the received transmission data 31, and returns a normal reception response message to the transmission side (step S34). To complete the procedure.

  When the above step S33 is “NO” and the collation does not match, the arithmetic control unit 22 checks the consistency with the latest data at the registration time, for example, in the collation item of the common unit, in addition to the well-known bit error check (procedure S35). ) In the case of consistency (YES in step S36), the arithmetic control unit 22 records the received data 31 in the storage unit 23 and displays it on the screen. A response message of normal reception is returned to the side (step S37). On the other hand, the arithmetic control unit 22 edits the recorded product information on a predetermined screen for the cooking place and displays the product information for each product (step S38).

  The arithmetic control unit 22, for example, inverts the screen display (step S <b> 39) when receiving the preparation start designation of the displayed product by the cook from the input unit 25, and contributes to the designation confirmation for the cook. Next, for example, when the cook prepares the ingredients and completes the preparation, the calculation control unit 22 accepts the designation of the display merchandise by the cook from the input unit 25 (step S40), and the screen display is deleted (procedure). S41). This erased data is held in the storage unit 23 so that it can be recalled for a predetermined period.

  This procedure is also well known, but since the confirmation of duplicate data reception becomes strict by arranging a large number of collation items, such as at least three in the common part of the transmission data format, the customer is identified by erroneous duplicate data determination. It is possible to avoid a situation in which the order items are missing. On the other hand, although not included in the above description, data that is clearly different can be confirmed by retransmission due to the consistency of comparison of the whole.

  In particular, adding the entry input time as the registration time to the collation item is a numerical value different from the sequence number, which is preferable in terms of collation, and further adds value to the time-series sequence number. Although it has been described that the registration time is recorded at the time of the first order and is used as fixed data, it may be used by adding the time for each entry recorded for data collection.

  Since such a configuration is adopted, the ordered product can be provided to the customer in a short time without any omission, without significantly changing the conventionally known configuration, which is effective in improving the service to the customer.

  By using multiple verification items in the transmission data, duplicate data can be detected easily and with high reliability, eliminating missing products for orders, and receiving orders in a short time by notifying the product assortment site for each order entry. It can be applied to uses where it is necessary to be able to provide products to customers. In other words, not only for kitchen displays, but also for customer service in sales systems where products are ordered at manufacturing sites, warehouses, etc., through POS systems in face-to-face sales or OES (order entry service) in direct entry order by customers. It can be applied to.
