Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings.
This embodiment is a case where the present invention is applied to a situation management device for managing whether a seat is in use or unused in restaurants such as family restaurants and taverns. is there. Incidentally, the state in use is defined as the period from the receipt of the order of the customer who arrived at the seat to the end of the accounting, and the other state being in the unused state.

  FIG. 1 is an overall configuration diagram of an order management system constructed in a restaurant according to the present embodiment. This system includes a plurality of handy terminals 1 and an order management device 3 having a wireless unit 2 capable of wireless communication with the handy terminals 1.

  The handy terminal 1 is used by a customer clerk called waiter or waitress to carry data for menu items ordered by customers. Each handy terminal 1 includes a keyboard for inputting a menu code, a table number, the number of customers, a customer service representative ID, and the like, and a display for displaying keyed data. Each handy terminal 1 has a built-in wireless circuit, and performs wireless data communication with a wireless unit 2 attached to a ceiling or the like in the passenger seat.

  The order management device 3 includes a computer device such as a personal computer or a workstation, and includes a menu database 4 and an order database 5 as databases necessary for order management at restaurants. The menu database 4 stores menu codes, item names, prices, and the like as menu item data that can be provided at the restaurant. The order database 5 stores the menu code, the order quantity, the order amount, etc. as the data of the menu item ordered by the customer together with the slip number of the order slip issued to the customer.

  The order management apparatus 3 is connected to a POS (Point Of Sales) terminal 7, a slip issuing machine 8, a kitchen terminal 9, and a passenger seat management terminal 10 via a LAN (Local Area Network) 6. The POS terminal 7 processes the accounts of customers who have finished eating and drinking. The slip issuing machine 8 prints and issues an order slip indicating the customer's order contents. The kitchen terminal 9 performs display or printing for informing the kitchen of the contents of the menu item ordered from the customer.

  The passenger seat management terminal 10 is a computer device that functions as a situation management device of the present invention, and is installed, for example, in the vicinity of a store entrance. The principal part structure of the passenger seat management terminal 10 is shown with the block diagram of FIG. The passenger seat management terminal 10 includes a CPU (Central Processing Unit) 11 as a control unit body. The CPU 11 is connected to a ROM (Read Only Memory) 13, a RAM (Random Access Memory) 14, a clock unit 15, a communication interface 16, and an HDD (Hard Disk Drive) via a bus line 12 such as an address bus and a data bus. A controller 18 of the device 17, a controller 20 of the display 19, a controller 22 of the keyboard 21, an interface 24 of the mouse 23, etc. are connected.

  The clock unit 15 measures the current date and time. The communication interface 16 is connected to the LAN 6. The display 19 displays a passenger seat status screen, which will be described later. The keyboard 21 and the mouse 23 are used as input means for the passenger seat status screen.

  The ROM 13 stores fixed data such as a basic program. The RAM 14 has various memory areas for temporarily storing variable data. The HDD device 17 stores programs and setting data necessary for the computer device to operate as the passenger seat management terminal 10.

  In the passenger seat management terminal 10 having such a configuration, a passenger seat management table 30 having a data structure shown in FIG. In FIG. 3, the table number area 31 stores table numbers set differently for each table in order to individually identify all tables (customer seats) installed in the restaurant. The floor number area 32 stores a number indicating the floor (floor) on which the table with the corresponding table number is installed.

  The status area 33 stores status data S indicating the current state (vacant seat, seated, in use or in preparation) of the corresponding table number. Here, the vacant seat (S = 0) means a state in which a customer can be seated. Sitting (S = 1) means a state in which a customer who has entered the store is guided and receives an order. In use (S = 2) means a state in which a seated customer places an order, finishes eating and drinking, and accounts for it. Preparing (S = 3) means a state from when a customer who has finished eating and drinking leaves the seat until the next customer can be seated.

  The start time stores the time when the status data S in the corresponding status area 33 is updated. The number of people memorizes the number of customers who arrived at the table with the corresponding table number. The elapsed time stores the elapsed time from the start time set in the corresponding start time area 34.

  Here, the audience management table 30 is associated with identification information (table numbers) for identifying a plurality of management targets (passenger seats), and indicates whether the management target is in an unused state or in use. In addition to storing status information S to be distinguished, it functions as a storage unit that stores an elapsed time from the use start time for a management target in use.

  Therefore, the CPU 11 controls the management operation of the passenger seat situation according to the procedure shown in the flowchart of FIG. This control procedure is realized by a control program stored in the ROM 13 or the HDD device 17.

  When the management operation is started, the CPU 11 performs an initialization process as ST (step) 1. In this initialization process, the status data S, start time, number of persons, and elapsed time data in the passenger seat management table 30 are reset to “0”. Further, the data in the floor number memory formed in the RAM 14 is initialized to a default value, for example, “1”.

  When the initialization process is completed, the CPU 11 creates display data of the passenger seat status screen 40 based on the data of the passenger seat management table 30 as ST2, and outputs the display data to the display controller 20. The display controller 20 controls the display 19 to display the passenger seat status screen 40.

  An example of the passenger seat status screen 40 is shown in FIG. The passenger seat status screen 40 includes an operation box 41 for selecting any one of the floor numbers displayed in a pull-down display, and each table arranged in the floor of the floor number stored in the floor number memory. A display area 43 of a table icon 42 indicating each of them, and a residence time zone selection button 44 set in four stages of “vacant seat”, “0 to 60 minutes”, “60 to 120 minutes” and “120 minutes or more” Is displayed. Here, the residence time zone selection button 44 functions as a residence time zone accepting unit that accepts selection input of any one of the residence time zones divided in stages.

  In the case of the screen example of FIG. 6, the CPU 11 acquires the table number (TBLxxx) to which the floor number selected by the operation box 41 is assigned from the audience management table 30. Then, a table icon 42 is created for each acquired table number, and each table icon 42 is arranged in the display area 43 in the order of the table number. Moreover, CPU11 reads the status data S memorize | stored corresponding to the table number for every acquired table number. When the status data S indicates seating (S = 1), “sitting” is displayed on the table icon 42 of the corresponding table number. When the status data S indicates that the status data is being used (S = 2), the number data stored in correspondence with the status data S is read and displayed on the table icon 42 of the table number. When the status data S indicates that preparation is in progress (S = 3), “preparing” is displayed on the desk icon 42 of the corresponding desk number. When the status data S indicates a vacant seat (S = 0), nothing is displayed on the desk icon 42 of the corresponding desk number. At this time, the background color of each desk icon 42 may be changed depending on the status data S. Further, in the case where the status data S is the table icon 42 indicating that it is in use, the background color of the table icon 42 may be varied depending on the elapsed time stored corresponding to the table number.

  When the passenger seat status screen 40 is displayed on the display 19, the CPU 11 waits for an input to the screen 40 as ST3 or to receive an external interrupt signal as ST4 (reception means). When an interrupt signal is received via the communication interface 16, the CPU 11 executes information processing according to the type of the interrupt signal.

  Here, the interruption signals include at least a seating interruption signal (ST5), an order interruption signal (ST6), an accounting interruption signal (ST7), and a cleanup completion interruption signal (ST8).

  A seating interruption signal is generated when a seating operation is performed in the handy terminal 1. That is, when the store clerk in charge of the customer guides the customer who has visited the store to one of the tables in the guest seat, the customer terminal 1 is operated to input the table number of the table and the number of customers. Then, a seating command including the table number and the number of persons data is wirelessly transmitted from the handy terminal 1 to the order management device 3. Upon receiving this seating command, the order management apparatus 3 creates an order data file in which the desk number in the command is set and registers it in the order database 5. Further, a seating interruption signal including the table number and the number of people in the command is generated and transmitted to the passenger seat management terminal 10 via the LAN 6.

  When the seating interruption signal is received (YES in ST5), the CPU 11 searches the passenger seat management table 30 as ST51 and sets the status data S corresponding to the table number included in the interruption signal to a value indicating an empty seat (S = 0). ) To a value (S = 1) indicating the seating. In ST52, data on the number of people included in the interrupt signal is set in the number of people area 35.

  The order interrupt signal is generated when an order operation is performed at the handy terminal 1. In other words, when a customer clerk receives an order for a menu item from a customer at the customer's seat, he / she operates the handy terminal 1 and inputs the code of the menu item, the order quantity, etc. together with the desk number of the table where the customer is wearing To do. Then, an order command including a desk number and order data is wirelessly transmitted from the handy terminal 1 to the order management apparatus 3. Upon receiving this order command, the order management apparatus 3 searches the order database 5, calls the order data file in which the desk number in the command is set, and registers the order data in the command in this order data file. Further, print data of the order slip is generated from the desk number and the order data in the command, and transmitted to the slip issuing machine 8 via the LAN 6 to print and issue the order slip. Furthermore, cooking instruction data is generated and transmitted to the kitchen terminal 9 via the LAN 6 to make a cooking instruction for the ordered menu item. Further, the order management device 3 generates an order interruption signal including the desk number in the command and transmits it to the passenger seat management terminal 10 via the LAN 6. Here, the order interruption signal functions as first information indicating that the management target (the passenger seat) has changed from the unused state to the in-use state.

  When the order interruption signal is received (YES in ST6), the CPU 11 searches the audience management table 30 in ST61, and obtains status data S corresponding to the desk number included in the interruption signal as a value indicating seating (S = 1). ) To a value (S = 2) indicating that it is in use (state update means). Further, the current time data measured by the clock unit 15 is acquired as ST62 and set in the start time area 34. Thereafter, as ST63, the counter is started so that the elapsed time n of the elapsed time area 46 is counted up every time the time of the clock unit 15 elapses 1 second.

  The accounting interrupt signal is generated when an accounting operation is performed at the POS terminal 7. That is, when a salesclerk in charge of accounting receives an order slip from a customer who has finished eating and drinking, he operates the POS terminal 7 and inputs the slip number. Then, an inquiry command including the slip number is transmitted from the POS terminal 7 to the order management apparatus 3. Upon receiving this inquiry command, the order management apparatus 3 searches the order database 5, calls the order data file in which the order number in the command is registered, and stores the order data stored in the order data file at the POS terminal 7. Send to. The POS terminal 7 executes accounting processing based on the order data received from the order management device 3.

  The order management apparatus 3 that has transmitted the order data file of the order data file to the POS terminal 7 generates an accounting interrupt signal including the desk number of the order data file and transmits it to the passenger seat management terminal 10 via the LAN 6. Here, the accounting interruption signal functions as second information indicating that the management target (the passenger seat) has changed from the used state to the unused state.

  When the accounting interruption signal is received (YES in ST7), the CPU 11 searches the audience management table 30 as ST71, and uses the status data S corresponding to the table number included in the interruption signal as a value indicating that it is in use (S = From 2), it is updated to a value (S = 3) indicating that preparation is in progress (state update means). In ST72, the start time in the start time area 34 and the elapsed time n in the elapsed time area 36 are reset to “0”. In ST73, the elapsed time n counter is stopped.

  The clearing completion interrupt signal is generated when a clearing completion operation is performed in the handy terminal 1. That is, when the customer clerk completes the cleanup of the table from which the customer leaves, he / she operates the handy terminal 1 and inputs the table number of the table. Then, a cleanup completion command including a desk number is wirelessly transmitted from the handy terminal 1 to the order management device 3. The order management apparatus 3 that has received this clearing completion command calls up the order data file in which the table number in the command is set from the order database 5 and stores it as an accounted data file. Further, a cleanup completion interrupt signal including the table number in the command is generated and transmitted to the passenger seat management terminal 10 via the LAN 6.

  When receiving the clean-up completion interrupt signal (YES in ST8), the CPU 11 searches the audience management table 30 as ST81 and sets status data S corresponding to the table number included in the interrupt signal to a value indicating that it is being prepared ( The value is updated from S = 3) to a value (S = 0) indicating a vacant seat.

  On the other hand, when there is an input to the passenger seat status screen 40 via the input means of the keyboard 21 or the mouse 23 (YES in ST3), the CPU 11 executes a screen input process specifically shown in FIG.

  That is, when any one of the floor numbers is selected by the input of the operation box 41 (YES in ST11), the CPU 11 stores the selected floor number in the floor number memory of the RAM 14 as ST12. Thereafter, the process returns to ST2, and the passenger seat status screen 40 is updated. That is, the content of the display area 43 is changed to a table icon 42 indicating each table arranged in the floor number of the floor number stored in the floor number memory.

  On the other hand, when any one staying time zone is selected by the input of the selection button 44 (YES in ST13), the CPU 11 stores the floor number stored in the floor number memory from the audience management table 30 as ST14. Is extracted (table number, status S, start time, number of people, elapsed time n).

  Here, the process is divided depending on whether the selected time zone is “vacant” or not. In the case of “vacant seat” (NO in ST15), the CPU 11 extracts data with a status S of “0” from the passenger seat data extracted as ST15. Then, display data of a vacant seat confirmation screen in which only the table icon indicating the table number of the extracted data is arranged in the display area 43 is generated and output to the display controller 20. The display controller 20 controls the display 19 to display a vacant seat confirmation screen.

  After displaying the vacant seat confirmation screen, the CPU 11 stands by for confirmation operation as ST18. When a confirmation operation input is made via the input means (YES in ST18), the CPU 11 returns to the process of ST2 and returns the screen of the display 19 to the passenger seat status screen 40.

  When the selected time zone is other than “vacant seat” (YES in ST15), the CPU 11 extracts data with a status S of “2” from the passenger seat data extracted as ST19. Furthermore, as ST20, data in the staying time zone in which the elapsed time n is selected is extracted from the extracted passenger seat data (extraction means).

  Thereafter, as ST21, the CPU 11 sorts the audience data extracted in the process of ST20 in descending order of elapsed time n (arranging means). And the display data of the residence time confirmation screen 50 formed by arranging the table icons 42 assigned with the table numbers of the audience data extracted as ST22 in the sorted order is generated and output to the display controller 20 (output means) ). The display controller 20 controls the display 19 to display a residence time confirmation screen 50.

  An example of the residence time confirmation screen 50 is shown in FIG. In the display area 43 of the staying time confirmation screen 50, the table icon 42 to which the table number of the audience data extracted in the process of ST20 is assigned, that is, the seat in the in-use state, becomes the in-use state. Table icons 42 corresponding to the seats in the staying time zone in which the elapsed time n is selected are displayed in the order of longer staying time. Further, the elapsed time n of the seat of the table number assigned to the table icon 42 is displayed below the table icon 42 in correspondence with each table icon 42.

  Here, the output means is means for causing the display to display and output a screen (residence time confirmation screen 50) showing the identification information (table number) of the management object (passenger seat) extracted by the extraction means in the order arranged by the arrangement means. It is. Further, the output means displays and outputs the management object (passenger seat) identification information (table number) extracted by the extraction means and the elapsed time n from the current use start time of the management object.

  After displaying the residence time confirmation screen 50, the CPU 11 waits for a confirmation operation as ST23. When a confirmation operation input is made via the input means (YES in ST23), the CPU 11 returns to the process of ST2 and returns the screen of the display 19 to the passenger seat status screen 40.

  Thus, in the present embodiment, for example, in a state where the passenger seat status screen 40 shown in FIG. 6 is displayed on the display 19, the operator operates the keyboard 21 or the mouse 23 to “60 to 120 minutes”. When the operation time is input to the residence time zone selection button 44a, the screen of the display 19 is switched to the residence time confirmation screen 50 shown in FIG. As shown in FIG. 7, on the staying time confirmation screen 50, only the table icon 42 of the passenger seat whose elapsed time n since the passenger seat state is in use is 60 minutes or more and less than 120 minutes is displayed. Therefore, the operator can easily grasp the seats that have elapsed time of 60 minutes or more and less than 120 minutes after receiving the customer's order by simply looking at the residence time confirmation screen 50.

  In the present embodiment, the table icons 42 displayed on the residence time confirmation screen 50 are arranged and displayed in descending order of the residence time. Therefore, the operator can grasp on the residence time confirmation screen 50 the passenger seats whose elapsed time after receiving the customer's order is 60 minutes or more and less than 120 minutes, in order of increasing elapsed time. Therefore, the next vacant table can be easily predicted, and the convenience of store operation can be improved.

  In the present embodiment, a “vacant seat” button is provided in the stay time zone selection button 44. Then, when the “vacant seat” button is operated and input, the passenger seat data whose status S is “0” is extracted from the passenger seat management table 30. Then, an empty seat confirmation screen in which only a table icon indicating the table number of the extracted data is arranged in the display area 43 is displayed on the display 19. Therefore, the operator can easily grasp the vacant seats by simply looking at the vacant seat confirmation screen. Therefore, customers who come to the store can be smoothly guided to vacant seats, and serviceability can be improved.

  The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.

  For example, in the above-described embodiment, the table icons 42 only for the seats in use are sorted and displayed on the residence time confirmation screen 50 in the order of the residence time, but are sorted and displayed in the order of the residence time. It may be output. Further, as shown in FIG. 8, even if only the table icon 42 of the seat in use is displayed on the stay time confirmation screen 50 without sorting, the elapsed time after receiving the order is displayed. An effect that the seats in the predetermined time zone can be easily grasped can be achieved. Further, instead of displaying the elapsed time n below each desk icon 42, the elapsed time n may be displayed inside the desk icon 42 as shown in FIG.

  In the embodiment, the output means displays on the display a screen (residence time confirmation screen 50) showing the identification information (table number) of the management object (seat number) extracted by the extraction means in the order arranged by the arrangement means. Although the display means is used, the output means is not limited to this. For example, identification information (table number) of the management target (passenger seat) extracted by the extraction means is transmitted and output to the order management device 3 via the LAN 6 and further transmitted to the handy terminal 1 via the wireless unit 2. The residence time confirmation screen 50 may be confirmed on the display of the handy terminal 1. Similarly, it may be transmitted to the POS terminal 7 via the LAN 6 so that the stay time confirmation screen 50 can be confirmed on the display of the POS terminal 7.

  Moreover, although the said embodiment applied this invention to the condition management apparatus for managing whether the seat of the restaurant is in use or an unused state, this invention is limited to this. It is not something. For example, a status management device for managing whether the karaoke room of the karaoke box is in use or unused, or the parking space in the parking lot is in use or unused The present invention can be similarly applied to a situation management apparatus for managing whether there is any.

  Furthermore, in the above-described embodiment, the case where the function for carrying out the invention is recorded in advance in the apparatus has been described.
