Description

Description: TECHNICAL FIELD The present invention relates to an order data management device used in restaurants such as restaurants and fast food restaurants.

[Prior art] In recent years, in this type of restaurant, waitresses and waiters have a portable order-receiving wireless terminal (hereinafter referred to as a handy terminal) in which a wireless circuit is incorporated. By making these handy terminals and the kitchen printer installed in the kitchen wirelessly connectable via a repeater, each customer service representative receives orders from customers at the customer seats and inputs them to their own handy terminal. In some cases, an order data management device that transmits order data generated from each handy terminal to a kitchen printer via a repeater and prints out the data is employed.

By adopting this type of equipment, each customer service representative does not need to go to the kitchen to report the contents of the order received at the customer's seat, which simplifies the order receiving operation and reduces the number of order errors. is there.

Further, the person in charge of cooking in the kitchen may start cooking based on the order data printed by the kitchen printer. Then, when the cooked product is completed, it is placed on a table provided between the kitchen and the audience seats. In this way, the customer service representative carries the cooked food to the customer who has received the order and serves it.

By the way, in a large restaurant that can accommodate many customers at once, for example, Japanese food,
We have special kitchens for Western food, Chinese food, etc. Each kitchen has its own kitchen printer. In this case, the print output destination of the order data generated from each handy terminal is arranged according to the content thereof. Specifically, data specifying the kitchen printer as the print output destination for each order data is specified in advance. When the setting is made and the order data is input, the corresponding printer designation data is read out, and the control is made so that the order data is transmitted to the chitchin printer designated by this data. When a printout of the order data becomes impossible due to a malfunction of the kitchen printer or the like, a backup function that can output the order data to another preset kitchen printer is known.

[Problems to be Solved by the Invention] However, in a conventional order data management apparatus provided with a plurality of kitchen printers, a backup function of a kitchen printer has the following problem. That is, since each kitchen printer is installed in a dedicated kitchen, the cook in charge of each kitchen prints out the order data as backup data from the kitchen printer, and prints out the output contents of the corresponding kitchen. I had to contact the cook. For this reason, when the store is crowded, there is a case where the contact is delayed and the start of the cooking is delayed, or the contact is forgotten and the cooking is not performed.

On the other hand, in an apparatus having no kitchen printer backup function, order data corresponding to a kitchen printer that cannot be printed out is not output, which again inconveniences customers.

Such a problem is caused by the customer service staff always grasping the normal / abnormal state of each kitchen printer and receiving an order for a kitchen printer that cannot print out, for example, informs the customer that cooking is slightly delayed. In addition, he / she can immediately take an appropriate action by immediately visiting the corresponding kitchen and informing the person in charge of the order of the order. However, in the prior art, it is difficult for each service clerk to always accurately grasp the state of each kitchen printer. Could not take any action.

Accordingly, the present invention provides a method for enabling each customer service staff having a wireless terminal for receiving orders to accurately grasp the status of each kitchen printer at all times. It is an object of the present invention to provide an order data management device that enables each user to take an appropriate action and improve serviceability.

[Means for Solving the Problems] According to the first invention of the present application, order data input from an input unit is displayed on a display unit and stored in a registration buffer, and a station opening instruction is performed in response to an input operation of a transmission key. A plurality of order receiving wireless terminals for wirelessly transmitting all order data in the registration buffer, a plurality of kitchen printers for receiving and printing out order data from each of the order receiving wireless terminals, and each order receiving terminal. The relay machine controls data transmission and reception with each kitchen printer. The relay machine periodically monitors the normal / abnormal state of each kitchen printer, and each of the printer status monitoring units obtained by the monitoring unit. State information holding means for storing and holding the state information of the kitchen printer, and the state information of each kitchen printer stored and held by the holding means, State information transmitting means for wirelessly transmitting to the line terminal, each order receiving wireless terminal, upon receiving the state information of each kitchen printer from the repeater, displays at least identification data indicating the abnormal state of the kitchen printer And an abnormal printer display control means to be displayed on the unit.

The second invention of the present application is directed to an abnormal printer detecting means for detecting an abnormal kitchen printer upon receiving status information of each kitchen printer from the repeater in place of the first wireless terminal for receiving orders, and detecting the abnormal printer. Determining means for determining whether or not the order data output to the abnormal printer detected by the means is stored in the registration buffer; and an abnormal kitchen to which the order data is output when the determining means determines that the order data is present. An order receiving wireless terminal including an abnormal printer display control means for displaying identification data indicating a printer on a display unit is provided.

Then, the abnormal printer display control means may cause the display unit to display message data indicating the trouble status together with the identification data indicating the abnormal kitchen printer.

[Operation] According to the first aspect of the present invention, the normal / abnormal state of each kitchen printer is periodically monitored by the relay device, and the status information of each kitchen printer is stored and held in the relay device. In this state, when the customer service clerk inputs order data from the customer via the input unit of the order receiving wireless terminal and performs an input operation of the transmission key, a station opening instruction is performed from the order receiving wireless terminal. When a wireless line with the repeater is formed,
The input order data is wirelessly transmitted to the repeater, and further transmitted to the corresponding kitchen printer for printing out. In addition, in response to the instruction to open the station from the wireless terminal for order, the status information of each kitchen printer is wirelessly transmitted from the repeater to the wireless terminal for order, thereby displaying on the display of the wireless terminal for order. Indicates identification data indicating at least a kitchen printer in an abnormal state. Therefore,
The service clerk can grasp the normal / abnormal state of each kitchen printer from the contents displayed on the display unit.

According to the second aspect of the present invention, when the status information of each kitchen printer is wirelessly transmitted from the repeater to the order receiving wireless terminal in response to the station opening instruction from the order receiving wireless terminal, the information is transmitted. In the order-receiving wireless terminal that has received the abnormal kitchen printer, the identification data indicating the abnormal kitchen printer is displayed on the display unit only when the order data is input to be output to the abnormal kitchen printer. Is displayed. Therefore, the receptionist can immediately confirm whether or not the customer's order data is output from the optimal kitchen printer.

Then, the message data indicating the failure status of the abnormal kitchen printer is displayed together with the identification data indicating the abnormal kitchen printer, so that the customer service representative can take more detailed measures.

The printer status information management table 74 corresponds to
An abnormality flag F which is set to "1" when the kitchen printer of the KP number is in an abnormal state is provided.

Then, the CPU 10 of the station 1 executes the processing shown in the flowchart of FIG. 8 at regular intervals, and monitors the normal / abnormal state of each of the kitchen printers 31 to 3N. That is, the flowchart starts when a certain time has elapsed from the previous same processing, and after the built-in counter n is initialized to “1”,
The transmission controller 18 transmits a status inquiry message to the kitchen printer 2n of KP number n via the transmission line 4, and waits for a response from the kitchen printer 2n. Here, the response from the kitchen printer 2n is received, and if the response indicates a normal state, the status information [00] is stored in the status information area of the KP number n in the printer status information storage buffer 30 provided in the RAM 12.

FIG. 9 shows a wireless transmission procedure between the handy terminal side wireless circuit 63 and the wireless unit side wireless circuit 26 at this time. That is, the handy terminal-side wireless circuit 63 first wirelessly transmits a transmission start character (ENQ) for instructing the start of a station, and has a response from the wireless unit 5. Upon receiving the transmission start character (ENQ), the radio unit side radio circuit 26 determines whether or not the data can be received. If the data can be received, an acknowledgment (ACK) is returned. ) Is wirelessly transmitted to the handy terminals 31 to 3M instructed to open the station.

Here, when an acknowledgment (ACK) is transmitted, the handy terminal side wireless circuit 63 wirelessly transmits all order data (TEXT) in the registration buffer 72 and waits for a response from the wireless unit 5 to instruct the station closing. Transmission end character (EO
T) is wirelessly transmitted and the processing ends. If a negative acknowledgment (NAK) is transmitted, the handy terminal side radio circuit 63 cannot transmit all the order data in the registration buffer 72, and thus immediately transmits the transmission end character (EOT) by radio and ends.

On the other hand, the CPU 22 of the radio unit 5
When the data of the printer status information storage buffer 30 is received via the CPU 23, the program control is performed so that the data received this time instead of the data received by the previous monitoring processing is stored and held in the predetermined memory 6 of the RAM 23. (State information holding means) In addition, the CPU 22 of the wireless unit 5 uses the wireless circuit 26 to transmit a transmission start character (ENQ) from the handy terminals 31 to 3M.
Is received, the program is controlled so that the data in the printer status information storage buffer 30 stored and held in the RAM 23 is added to the response message (ACK or NAK) and wirelessly transmitted. (Status Information Transmitting Means) When the CPU 60 of each of the handy terminals 31 to 3M receives the data of the printer status information storage buffer 30 added to the response message to the transmission start character (ENQ), the received data is transferred to the RAM 62. After being set in the printer status information management table 74, the program is controlled to execute the processing shown in FIG. That is, in step (hereinafter abbreviated as ST) 1, all the abnormality flags F corresponding to each KP number in the printer status information management table 74 are all initialized to “0”. Also, the pointer P of the area 73
And the counter n in the area 77 are each initialized to “1”. Next, as ST2, the printer status information management table 7
4 is searched, and the status information corresponding to KP number n is normal [00]
Or abnormal [01], [02], [03] or [04] (abnormal printer detecting means). And normal [00]
, The KP number counter n is updated by “+1”, and the KP number in the printer status information management table 74 is similarly changed.
Check the state information corresponding to the number n + 1.

On the other hand, if the status information for the KP number n is abnormal [01], [02], [03], [04] in ST2, the KP number n is stored in the abnormal KP number memory 76. further,
The menu code stored in the pointer P of the registration buffer 72 is read as ST3, the KP number corresponding to the menu code is recognized from the menu table 71, and stored in the output KP number memory 75. Then, the output KP number memory 75
The KP number is compared with the KP number in the abnormal KP number memory 76 (determination means). If the two KP numbers match, the abnormality flag corresponding to the relevant KP number in the printer status information management table 74 is set to “1”. set. If the two KP numbers do not match, the above processing is not performed. After that, only the pointer P “+1” is updated, and the processing from ST3 onward is repeated until the pointer P exceeds the registered number m. If the pointer P exceeds the registration number m, the KP number counter n is updated by "+1", and the process returns to ST2 to return to the KP number n + 1 of the printer status information management table 74.
Check the status information corresponding to.

STP KP number counter n is kitchen printer 21-2N
If the number N exceeds the number N, the abnormality flag F in the printer status information management table 74 is checked. Then, if all the flags F are “0”, the process is terminated. On the other hand, if at least one of the flags F is "1", all the KP numbers set in the flag F "1" are extracted and displayed on the display 52 (abnormal printer display control means). The buzzer 66 sounds and the process ends.

In the present embodiment having such a configuration, the normal / abnormal state of each of the kitchen printers 21 to 2N is periodically monitored by the station 1, and the latest state information of each of the kitchen printers 21 to 2N is constantly updated by the wireless unit 5. It is stored and held in the RAM 24.

On the other hand, when the customer arrives at the seat, he or she goes to the seat, receives an order from the customer, and inputs the details of the order by operating the keyboard 51 of the dedicated handy terminal 31-3M. Then, the order data including the menu code and the number is stored in the registration buffer 72. Here, when the transmission key K4 is input to instruct the transmission of the order data, the wireless circuit 63 of the handy terminals 31 to 3M instructs the wireless unit 5 to open the station. In this state, if there is an acknowledgment (ACK) from the wireless unit 5, the order data is wirelessly transmitted to the wireless unit 5.

At the station 1 receiving the order data, the customer slip is issued by the printer 21 and the kitchen printers 21 to 2N of the kitchen to be cooked are selected, and the corresponding kitchen printers 21 to 2N are transmitted via the transmission circuit 4. The order data is sent to. However, when the corresponding kitchen printer 21 to 2N is in an abnormal state, the order data is transmitted to a backup kitchen printer selected according to a preset priority order, for example.

In the kitchen printers 2 to 2N that have received the order data, the order data is printed on the recording paper by the printing unit 44, so that the cook in charge of the kitchen starts cooking according to the printed contents. If the printed order data is data that has been backed up and output, the contents of the print are notified to the person in charge of cooking at the corresponding kitchen.

On the other hand, in the present embodiment, the handy terminal 31-3M
When the transmission key K4 is input and a radio station 5 is instructed to open a station, the response from the radio section 5 is returned with the status information of each of the kitchen printers 21-2N added. Here, in the handy terminals 31 to 3M, the received status information is stored in the printer status information management table 74, and a kitchen printer in an abnormal state is detected. Then, it is determined whether or not the kitchen printer designated as the output destination of the order data stored in the registration buffer 72 is in an abnormal state. If there is an abnormal kitchen printer among the kitchen printers specified as the output destination of the order data, the KP number of the kitchen printer is displayed on the display 52, and the buzzer 66 sounds and the customer service is received. Call attention to the person in charge.

FIG. 11 shows a display example of the KP number of the abnormal kitchen printer when the order data is normally transmitted to the wireless unit 5.

Therefore, by checking the display as shown in FIG. 11, the customer service clerk can recognize that there is an item whose cooking may be delayed among the menu items ordered by the customer. As a result, it is possible to notify the customer that cooking may be delayed, so that the customer does not have distrust of cooking even if cooking is delayed. In addition, the customer service representative can go to the kitchen where the kitchen printer in abnormal status is installed or the kitchen where the kitchen printer with backup output is installed, and promptly and surely inform the cooking staff of the customer's order data. Possible, thereby minimizing cooking delays.

As described above, according to the present embodiment, the customer service clerk inputs order data from the customer to the handy terminal and sends the transmission key K4.
When the kitchen printer to which the input order data is output is in an abnormal state, the KP number of the abnormal kitchen printer is displayed on the display 52. The normal / abnormal state of 21 to 2N can always be accurately recognized, and by taking appropriate measures, the customer will not be inconvenienced and the serviceability can be improved.

The present invention is not limited to the above embodiment.
For example, in the above-described embodiment, it is determined whether the kitchen printer designated as the print output destination of the order data registered in the handy terminals 31 to 3M is an abnormal kitchen printer, and if the abnormal kitchen printer, the corresponding KP number is displayed. Output is shown, but Handy Terminal 31 ~ 3M
, The status information of each of the kitchen printers 21 to 2N returned in response to the channel opening instruction may be recognized, and all kitchen printers in an abnormal state may be displayed on the display 52. Even in this case, the customer service staff can always confirm the normal / abnormal state of each of the kitchen printers 21 to 2N based on the displayed contents. Therefore, when an order is output from the customer to the abnormal kitchen printer, an appropriate response can be easily taken in the same manner as in the embodiment.

Further, in the present invention, the failure status for the kitchen printer in the abnormal state is managed separately by the status information for each of the kitchen printers 21 to 2N. Therefore, when displaying the KP number of the abnormal kitchen printer on the handy terminals 31 to 3M based on this state information, it is possible to simultaneously display a message indicating the failure status. Less than,
An embodiment in this case will be described.

Fig. 12 is a handy terminal 31-3M corresponding to Fig. 10.
5 is a flowchart showing ST4 and subsequent steps in the CPU processing of FIG. Note that steps ST1 to ST4 are the same as those in the above embodiment, and a description thereof will be omitted. Also, FIGS. 1 to 9 are the same as those in the above-described embodiment, and a description thereof will be omitted. In ST4, when it is determined that the KP number counter n has exceeded the number N of the kitchen printers 21 to 2N, the KP number counter n is initialized to "1" again. Then, an abnormal flag F corresponding to the KP number n in the printer status information management table 74 is checked. Here, the abnormality flag F
Is reset to “0”, the counter n is set to “+”.
"1" is updated, and the abnormal flag of the KP number n + 1 is similarly checked.

On the other hand, when the abnormality flag F is set to “1”, a message indicating a failure state according to the state information corresponding to the KP number is displayed on the display unit 52. Thereafter, when the registration key K3 of the keyboard 51 is input, the KP number counter n is updated by "+1" and the abnormality flag F of the KP number n + 1 is checked. When the KP number counter n exceeds the number N of the kitchen printers 21 to 2N, this process ends.

With such a configuration, when the print output destination of the menu ordered by the customer is a kitchen printer in an abnormal state, the KP number of the printer and a message indicating the failure status are displayed on the display 52. One display example at this time is shown in FIG. If the registration key K3 is operated in this state, the display contents will not change unless there is another abnormal printer, and if so, the display contents will change to the KP number of the abnormal printer and the failure status message. I do. Therefore,
By checking the displayed contents, the customer service clerk can grasp not only the presence or absence of the abnormal kitchen printer but also the trouble state thereof, and can take more appropriate measures according to the trouble state. For example, in a system that does not have a backup function for a kitchen printer, if the failure situation of an abnormal kitchen printer is a simple one such as a paper jam, the service clerk can immediately eliminate the failure by himself.

[Effects of the Invention] As described in detail above, according to the present invention, each service clerk having a wireless terminal for receiving orders can always accurately grasp the state of each kitchen printer, and a kitchen in which printout is impossible. When order data for a printer is generated, each customer service representative can take an appropriate action and provide an order data management device that can improve serviceability.
