[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] Embodiment 1

[0034] This embodiment provides an article production tracking system, which is suitable for tracking the production process of an article when an article is produced through the flow of various production links, such as Figure 1 As shown, the article production tracking system 10 includes:

[0035] RFID (Radio Frequency Identification) tag 11, set on the paper receipt holder;

[0036] The barcode scanner 12 is connected to the gateway device 14 via a local area network, and is used to scan and obtain the order identification in the paper receipt at the beginning of the production of the item, and send the order identification to the gateway device 14;

[0037] The first RFID reader / writer 13 is connected to the gateway device 14 via a local area network, and is used to read the tag identification of the RFID tag 11 at the beginning of the production of the item, and send the tag identification to the gateway device 14;

[0038] The gateway device 14 is connected to the server 15 for communication, and is used to establish a correspondence between the order identifier and the label identifier by taking the time point at which the order identifier and the label identifier are received as the first time point, and send the correspondence and the corresponding first time point to the server 15;

[0039] The server 15 is used to receive the correspondence between the order identifier and the label identifier, and use the first time point as the start time point of the production start link corresponding to the order identifier;

[0040] The second RFID reader / writer 16 is arranged in the area corresponding to the production link of the article, connected to the gateway device 14 through the local area network, and is used to read the tag identification in the RFID tag when the paper receipt flows to the current production link, and send the tag identification to the gateway device 14;

[0041] The gateway device 14 is further configured to use the time point at which the tag identifier sent by the second RFID reader is received as the second time point, and send the tag identifier, the reader identifier of the second RFID reader 16 and the corresponding second time point to the server 15;

[0042] The server 15 is also used to, when receiving the tag identifier, the reader identifier of the second RFID reader 16 and the corresponding second time point, determine the current production link corresponding to the order identifier based on the pre-established correspondence between the reader identifier and the production link and the correspondence between the order identifier and the tag identifier, and use the second time point as the starting time point of the current production link.

[0043] The paper receipt holder is used to hold the paper receipt corresponding to the order, and the paper receipt includes production information for the items in the order, providing an operation basis for each production link of the items. The gateway device may be an edge gateway. The barcode scanner, the first RFID reader / writer, the second RFID reader / writer and the gateway device may be connected to a local area network, and the barcode scanner, the first RFID reader / writer and the second RFID reader / writer may communicate with the gateway device using a local area network communication protocol. The local area network may be implemented by a router.

[0044] An RFID tag 11 is set on the paper receipt clamp, and the RFID tag 11 has an RFID identification. When the paper receipt clamp holds the paper receipt, that is, at the starting stage of item production, the order identification in the paper receipt and the RFID identification in the RFID tag 11 are first associated. Therefore, during the circulation of the paper receipt, the RFID tag on the paper receipt clamp circulates with the paper receipt between the production starting stage and each production stage. During this circulation process, as long as the RFID identification is identified, the corresponding order identification can be determined, thereby determining whether the order is currently in the production starting stage or the production stage, as well as the starting time point corresponding to the current stage.

[0045] A barcode scanner 12 and a first RFID reader / writer 13 are set in the corresponding area of ​​the starting link of the item production. The barcode scanner 12 is used to scan the barcode or QR code on the paper receipt to obtain the order identification in the paper receipt. The first RFID reader / writer 13 is used to read the label identification of the RFID tag 11. The gateway device 14 receives the order identification obtained by the barcode scanner 12 and the label identification read by the first RFID reader / writer 13. If the time interval between receiving the order identification and the label identification is within the preset interval threshold, a corresponding relationship between the order identification and the label identification is established to associate the order identification in the paper receipt with the label identification in the RFID tag 11. The server 15 receives the corresponding relationship between the order identifier and the label identifier and the first time point, and saves the corresponding relationship between the order identifier and the label identifier before the production of the item corresponding to the order identifier is completed. In this way, the order identifier in the paper receipt and the label identifier in the RFID tag 11 are associated during the production process of the item, and the first time point is used as the starting time point of the production start link corresponding to the order identifier to track the time when the order identifier starts production.

[0046] A second RFID reader / writer 16 is respectively set in the corresponding area of ​​each production link of the item. When the paper receipt flows to the current production link, the item production personnel only need to place the paper receipt clamp holding the paper receipt into the sensing range of the second RFID reader / writer 16 set in the corresponding area of ​​the current production link. The second RFID reader / writer 16 can read the label identification in the RFID tag 11 on the paper receipt clamp, and send the label identification to the gateway device 14. The gateway device 14 uses the time when the label identification sent by the second RFID reader / writer 16 is received as the second time point, and sends the label identification, the reader / writer identification of the second RFID reader / writer and the second time point to the server 15. The server 15 determines the order identification corresponding to the label identification just received according to the corresponding relationship between the label identification and the order identification, and determines the current production link corresponding to the reader / writer identification just received according to the pre-established corresponding relationship between the reader / writer identification and the production link, thereby obtaining the current production link corresponding to the order identification, and uses the second time point as the starting time point of the current production link, thereby realizing the tracking of the production process of the items in the order, and can obtain the starting time point of each production link.

[0047] In one embodiment of the present application, the gateway device is further used for:

[0048] When sending the corresponding relationship and the corresponding first time point to the server, if the network communication fails, saving the corresponding relationship and the corresponding first time point, and sending the corresponding relationship and the corresponding first time point to the server after the network communication is restored; and / or

[0049] When sending the tag identification, reader identification and the corresponding second time point to the server, if the network communication fails, the tag identification, reader identification and the corresponding second time point are saved, and the tag identification, reader identification and the corresponding second time point are sent to the server after the network communication is restored.

[0050] The gateway device also has the function of saving information. If the gateway device fails to send information to the server, that is, the network communication between the gateway device and the server fails, the information will be saved. After the network communication between the gateway device and the server is restored, the information will be sent to the server, so that the server can obtain the starting time point of the production link of the items in the order, and realize the tracking of the production link of the items in the order, avoiding the problem of information failure to send due to network failure.

[0051] In one embodiment of the present application, the server is also used to: when determining that the current production link corresponding to the order identifier is the production termination link, cancel the corresponding relationship between the order identifier and the label identifier. When the server determines that the current production link corresponding to the order identifier is the production termination link, that is, the items in the order have been produced, the corresponding relationship between the order identifier and the label identifier is canceled, so that the paper receipt clamp can be used again to clamp paper receipts of other orders to achieve reuse. The second RFID reader / writer set in the corresponding area of ​​the production termination link can be set in the storage box of the paper receipt clamp, and the storage box is used to store the paper receipt clamp. After the production of the item is completed, the item production personnel can take down the paper receipt clamp holding the paper receipt and put it into the storage box, so that the second RFID reader / writer in the storage box can read the label identification of the RFID tag in the paper receipt clamp.

[0052] In one embodiment of the present application, the barcode scanner and the first RFID reader / writer are integrated into the gateway device, and are respectively displayed as a barcode scanning area and an RFID reading / writing area in the operation panel of the gateway device; the gateway device also includes a processor and a communication module, the communication module is used to communicate with the second RFID reader / writer and the server, the processor is used to establish a correspondence between the order identifier and the tag identifier, and send the correspondence and the corresponding first time point to the server through the communication module, and when receiving the tag identifier sent by the second RFID reader / writer, send the tag identifier, the reader / writer identifier of the second RFID reader / writer and the corresponding second time point to the server through the communication module. The barcode scanner and the first RFID reader / writer can be independent devices independent of the gateway device, or they can be integrated into the gateway device. When the barcode scanner and the first RFID reader / writer are integrated into the gateway device, the gateway device needs to be set in the area corresponding to the starting link of the item production, and the gateway device represents the first RFID reader / writer through the sensing area in the operation panel, that is, the RFID reading and writing area, and represents the barcode scanner through the scanning area in the operation panel. When it is necessary to establish a correspondence between the order identification and the label identification, it is only necessary to place the paper receipt holder in the RFID reading and writing area in the operation panel of the gateway device, and the first RFID reader / writer can read the label identification of the RFID label in the paper receipt holder, align the barcode or QR code of the paper receipt with the scanning area in the operation panel of the gateway device, and the barcode scanner can scan the barcode or QR code to obtain the order identification, so that the gateway device obtains the order identification and the label identification. The processor in the gateway device uses the time when the order identification and the label identification are obtained as the first time point, and establishes a correspondence between the order identification and the label identification, and sends the correspondence and the first time point to the server through the communication module. When the gateway device receives the tag identification sent by the second RFID reader through the communication module, the tag identification, the reader identification of the second RFID reader and the corresponding second time point are sent to the server through the communication module. By integrating the barcode scanner and the first RFID reader into the gateway device, the space occupied by the device can be reduced and it is convenient to use.

[0053] In one embodiment of the present application, the gateway device includes a display screen; the display screen is used to display prompt information corresponding to the starting link of item production, the prompt information is used to prompt the use of the scanner to scan the code and the use of the first RFID reader to read the tag identification, and is also used to display the establishment status of the correspondence between the order identification and the tag identification after obtaining the order identification and the tag identification; the display screen is also used to display relevant information of the order corresponding to the order identification, and the relevant information includes item information and / or user demand information; the display screen is also used to display the user tag of the user corresponding to the order identification, and the user tag includes user consumption characteristics and user preference characteristics.

[0054] When binding the paper receipt holder and the order, the display screen in the gateway device can prompt the item producer to use a barcode scanner to scan the barcode or QR code on the paper receipt, and use the first RFID reader to read the tag identifier in the RFID tag in the paper receipt holder. The display screen in the gateway device can also display the establishment status of the correspondence between the order identifier and the tag identifier after obtaining the order identifier and the tag identifier, that is, display the binding status of the paper receipt holder and the order, and the binding status includes successful binding or failed binding; the display screen in the gateway device can also display relevant information of the order corresponding to the order identifier, and the relevant information includes item information and / or user demand information. The item information can be, for example, the name of a specific dish, and the user demand information can be the user's taste information, such as not eating spicy food, etc.; the display screen in the gateway device can also display the user tag of the user corresponding to the order identifier, and the user tag can be the user's consumption characteristics and user preference characteristics. The user preference characteristics can be, for example, information such as the user's demand preferences in the current merchant.

[0055] In one embodiment of the present application, the server is further used to: determine the consumption time corresponding to the previous production link or the production start link according to the start time point of the current production link and the start time point of the previous production link or the production start link, and predict the remaining preparation time required for the item corresponding to the order identifier according to the total consumption time of the current production link and the historical order, and dispatch the distribution resources according to the remaining preparation time to distribute the item corresponding to the order identifier. After determining the start time points of two adjacent production links of an order, the server can subtract the start time point of the previous production link from the start time point of the latter production link to obtain the consumption time of the previous production link. For example, when the server obtains the first time point when the production start link and the second time point of the first production link, the server subtracts the first time point from the second time point to obtain the time consumed by the order from the start of production to the first production link, that is, the consumption time of the order in the production start link. After determining the starting time point of the current production link and the consumption time of the previous production link or the production start link, combined with the total consumption time of historical orders, the remaining preparation time required for the item corresponding to the order identifier can be predicted. For example, the total consumption time of the same item in the historical order as the order identifier is 10 minutes, and the consumption time of the order identifier in the previous production links is 5 minutes, then the remaining preparation time is 5 minutes. After determining the remaining preparation time of the item corresponding to the order identifier, the distribution resources can be dispatched according to the remaining preparation time to the merchant to collect the item corresponding to the order identifier for delivery. For example, when the remaining preparation time is 5 minutes, the distribution resources can be dispatched to arrive at the merchant in 5 minutes, thereby avoiding the distribution resources waiting for a long time at the merchant, thereby improving the distribution efficiency.

[0056] In one embodiment of the present application, the items include dishes, and the production process includes a dish preparation process and a meal packaging process. The item production tracking system in the embodiment of the present application can be applied to the field of takeout. In this case, the items to be produced are dishes, and the production process includes a dish preparation process and a meal packaging process. For different dishes, the dish preparation process can also be divided into more detailed processes, such as ingredient preparation process and cooking process.

[0057] The following uses the takeaway field as an example to illustrate the process of using the item production tracking system of the embodiment of the present application to track the production link of dishes. First, after receiving an order, the item production personnel, i.e., the back kitchen staff of the merchant, prints the order as a paper receipt, and uses a paper receipt clamp to clamp the paper receipt, aligns the barcode or QR code of the paper receipt with the scanner, and the scanner scans and obtains the order identification in the paper receipt. The back kitchen staff of the merchant then brings the paper receipt clamp close to the first RFID reader, and the first RFID reader reads the label identification of the RFID tag in the paper receipt clamp. The gateway device establishes a corresponding relationship between the order identification and the label identification, and sends the corresponding relationship and the corresponding first time point to the server. The server receives and saves the corresponding relationship between the order identification and the label identification, realizes the binding of the order identification and the label identification, and uses the first time point as the starting time point of the production start link corresponding to the order identification. Afterwards, when the paper receipt flows to the dish preparation stage, the merchant's kitchen staff brings the paper receipt holder close to the second RFID reader / writer set in the corresponding area of ​​the dish preparation stage. The second RFID reader / writer reads the tag identifier of the RFID tag in the paper receipt holder and sends it to the gateway device. The gateway device uses the time when the tag identifier sent by the second RFID reader / writer is received as the second time point, and sends the tag identifier, the reader / writer identifier of the second RFID reader / writer and the second time point to the server. The server determines that the current production stage corresponding to the order identifier is the dish preparation stage based on the pre-established correspondence between the reader / writer tag and the production stage, and the correspondence between the order identifier and the tag identifier. The server obtains the prompt information corresponding to the dish preparation stage from the order corresponding to the order identifier, such as user taste requirement information, and sends the prompt information to the gateway device. At the same time, the second time point is used as the starting time point of the current production stage. The gateway device forwards the prompt information to the display device set in the dish preparation stage, and the display device displays the prompt information. After reading the label identification of the RFID tag in the paper receipt holder through the second RFID reader, the kitchen staff of the merchant can clamp the paper receipt holder on the container containing ingredients (such as a vegetable basket), and prepare the ingredients according to the dishes in the paper receipt, and then produce the dishes according to the prompt information displayed on the display device. For example, the prompt information may be that the customer does not like spicy food, etc. At this time, the kitchen staff can not put chili when producing the dishes.Finally, the dishes are produced and need to be packaged. At this time, the kitchen staff takes the paper receipt from the paper receipt holder and puts the paper receipt holder into a storage box. The second RFID reader / writer set in the storage box reads the tag identifier of the RFID tag in the paper receipt holder and sends the tag identifier to the gateway device. The gateway device uses the time when the tag identifier sent by the second RFID reader / writer is received as the second time point, and sends the tag identifier, the reader / writer identifier of the second RFID reader / writer and the second time point to the server. The server determines the correspondence between the reader / writer identifier and the production link, and the correspondence between the order identifier and the tag identifier according to the pre-established correspondence between the reader / writer identifier and the production link, and the correspondence between the order identifier and the tag identifier. The current production link corresponding to the order identifier is the packaging and storage link. At this time, the prompt information corresponding to the packaging and meal delivery link is obtained from the order corresponding to the order identifier, such as information related to tableware, and the prompt information is sent to the gateway device. At the same time, the second time point is used as the starting time point of the packaging and meal delivery link, that is, as the end time point of the production of the items in the order. The gateway device forwards the prompt information to the display device set in the packaging and meal delivery link, and the display device displays the prompt information. The prompt information can be information related to tableware, for example, it can be that 2 sets of tableware are needed or no tableware is needed, etc. At this time, the back kitchen staff can prepare the corresponding tableware according to the prompt information for packaging. Through the above process, the server can obtain the starting time point corresponding to each production link, so that the consumption time corresponding to each production link can be determined according to the starting time point of each production link. According to the consumption time, the delivery efficiency of the order can be optimized, and the digitization of the kitchen production link in the takeaway field is realized, which helps merchants to measure their own production efficiency more accurately and provide data basis for optimizing production processes and assessing employee capabilities. Dishes that track the production link through the circulation of paper receipts can include, for example, spicy hot pot, spicy hot pot, rice noodles, rice noodles, noodles, etc.

[0058] The item production tracking system provided by the embodiment of the present application sets an RFID tag on a paper receipt holder, scans and obtains the order identification in the paper receipt by a scanner at the starting stage of item production, reads the tag identification in the RFID tag by a first RFID reader at the starting stage of item production, and establishes a corresponding relationship between the order identification and the tag identification by a gateway device, and sends the corresponding relationship and the corresponding first time point to a server. The server receives the corresponding relationship between the order identification and the tag identification, and uses the first time point as the starting time point of the production starting stage corresponding to the order identification. During the circulation of the paper receipt, the second RFID reader / writer set in the corresponding area of ​​the item production stage can obtain the RFID tag. The gateway device sends the tag identification, the reader identification of the second RFID reader and the second time point to the server. The server determines the current production link corresponding to the order tag according to the pre-established correspondence between the reader identification and the production link and the correspondence between the order identification and the tag identification, and uses the second time point as the starting time point of the current production link. Therefore, in the circulation of paper receipts, the tracking of the production links of items in the order can be achieved through the RFID tag set on the paper receipt clamp, the scanner and the first RFID reader set at the starting link of the item production, the second RFID reader set in the corresponding area of ​​the item production link, the gateway device and the server.

[0059] On the basis of the above technical solution, the server is further used to: after determining the current production link corresponding to the order identifier, obtain prompt information corresponding to the current production link from the order corresponding to the order identifier, and send the prompt information to the gateway device, wherein the prompt information includes user demand information;

[0060] The gateway device is also used to: send the prompt information to the display device corresponding to the current production link;

[0061] The system also includes: a display device, which is arranged in an area corresponding to the item production stage and is used to display prompt information corresponding to the current production stage.

[0062] A display device can also be set in the area corresponding to the item production link, and the prompt information corresponding to the current production link can be displayed through the display device. The prompt information can be user demand information, such as information such as precautions in the current production link, or information about items to be prepared in the current production link. Some information that needs to be emphasized (such as remarks in an order, or other error-prone information) can be highlighted. For example, in the cooking link, highlight the user's taste requirements, or, in the packaging link, highlight information related to tableware, etc. Displaying prompt information on a display device solves the problem in the prior art that paper receipts cannot provide special prompts for information in the order, which can improve the operating efficiency of item production personnel and reduce the probability of errors, thereby reducing the requirements for the experience and cognitive level of item production personnel and reducing labor costs.

By aligning the barcode or QR code on the paper receipt with the scanning area in the gateway device, the scanner 21 in the gateway device can scan the barcode or QR code on the paper receipt to obtain the order identification. By placing the paper receipt holder in the RFID reading and writing area of ​​the gateway device, the first RFID reader / writer can read the label identification of the RFID tag in the paper receipt holder. The processor will obtain the time point of the order identification and the label identification as the first time point, and establish a corresponding relationship between the order identification and the label identification, and send the corresponding relationship and the corresponding first time point to the server through the communication module 24. The server receives the corresponding relationship between the order identification and the label identification, and uses the first time point as the starting time point of the production starting link corresponding to the order identification. During the circulation of the order ticket, the second RFID reader / writer set in the area corresponding to the item production link reads the tag identifier of the RFID tag in the paper ticket holder and sends it to the gateway device. After the gateway device receives the tag identifier sent by the second RFID reader / writer through the communication module 24, it uses the receiving time as the second time point, and sends the tag identifier, the reader / writer identifier of the second reader / writer and the second time point to the server through the communication module 24. The server can then determine the current production link corresponding to the order identifier based on the pre-established correspondence between the reader / writer identifier and the production link, and the correspondence between the order identifier and the tag identifier, and use the second time point as the starting time point of the current production link.

[0071] In one embodiment of the present application, the gateway device also includes: a display screen, used to display prompt information corresponding to the starting link of item production, the prompt information is used to prompt the use of the scanner to scan the code and the use of the first RFID reader to read the tag identification, and is also used to display the establishment status of the correspondence between the order identification and the tag identification after obtaining the order identification and the tag identification; the display screen is also used to display relevant information of the order corresponding to the order identification, and the relevant information includes item information and / or user demand information; the display screen is also used to display the user tag of the user corresponding to the order identification, and the user tag includes user consumption characteristics and user preference characteristics.

[0072] When binding the paper receipt holder and the order, the display screen in the gateway device can prompt the item producer to use a barcode scanner to scan the barcode or QR code on the paper receipt, and use the first RFID reader to read the tag identifier in the RFID tag in the paper receipt holder. The display screen in the gateway device can also display the establishment status of the correspondence between the order identifier and the tag identifier after obtaining the order identifier and the tag identifier, that is, display the binding status of the paper receipt holder and the order, and the binding status includes successful binding or failed binding; the display screen in the gateway device can also display relevant information of the order corresponding to the order identifier, and the relevant information includes item information and / or user demand information. The item information can be, for example, the name of a specific dish, and the user demand information can be the user's taste information, such as not eating spicy food, etc.; the display screen in the gateway device can also display the user tag of the user corresponding to the order identifier, and the user tag can be the user's consumption characteristics and user preference characteristics. The user preference characteristics can be, for example, information such as the user's demand preferences in the current merchant.

[0073] In one embodiment of the present application, the gateway device further includes:

[0074] A storage module, used for storing the corresponding relationship and the corresponding first time point, and / or storing the tag identifier, the reader identifier and the corresponding second time point;

[0075] The processor is further configured to:

[0076] When sending the corresponding relationship and the corresponding first time point to the server through the communication module, if the network communication fails, the corresponding relationship and the corresponding first time point are saved in the storage module, and the corresponding relationship and the corresponding first time point are sent to the server after the network communication is restored; and / or

[0077] When the tag identification, reader identification and the corresponding second time point are sent to the server through the communication module, if the network communication fails, the tag identification, reader identification and the corresponding second time point are saved in the storage module, and the tag identification, reader identification and the corresponding second time point are sent to the server after the network communication is restored.

[0078] The storage module is used to save the information that failed to be sent to the server. After the network communication failure is restored, the information can be sent to the server, and the server can obtain the time point of the production link of the items in the order, so as to track the production link of the items in the order and avoid the problem of information failure to be sent when the network fails.

[0079] The gateway device including the above modules is a computing unit deployed locally and may have an operating system, such as an Android system, a Linux operating system, etc.

[0080] The gateway device provided in this embodiment can reduce the occupied space by integrating a barcode scanner and a first RFID reader / writer, and obtains the order identification in the paper receipt through the barcode scanner, and reads the label identification of the RFID tag in the paper receipt holder through the first RFID reader / writer. The processor establishes a correspondence between the order identification and the label identification, and sends the correspondence to the server through the communication module. The server receives and saves the correspondence between the order identification and the label identification. When the processor receives the label identification sent by the second RFID reader / writer, the processor sends the label identification, the reader / writer identification of the second RFID reader / writer and the corresponding second time point to the server through the communication module. The server identifies the current production link corresponding to the order identification, and uses the second time point as the starting time point of the current production link, thereby realizing the tracking of the production links of the items in the order.

[0081] Embodiment 3

[0082] This embodiment provides an article production tracking method, which is suitable for tracking the production process of an article when it is produced through the circulation of various production links, and can be executed by the above-mentioned article production tracking system, such as Figure 3 As shown, the article production method comprises the following steps:

[0083] Step 310: The barcode scanner scans and obtains the order ID in the paper receipt at the start of item production, and sends the order ID to the gateway device.

[0084] After a merchant receives an order and prepares to produce the items in the order, the item production personnel in the merchant need to print the order as a paper receipt and align the barcode or QR code in the paper receipt with the scanner. The scanner can obtain the order ID in the paper receipt and send the obtained order ID to the gateway device. The item production personnel can hold the paper receipt with a paper receipt clamp, so that the paper receipt clamp and the paper receipt are circulated together in various production links of the item. The paper receipt can provide an operational basis for the production of the items in the order.

[0085] Among them, the items may include dishes, and the production process may include a dish preparation process and a meal packaging and delivery process.

[0086] Step 320, the first RFID reader reads the tag identification of the RFID tag at the start of the item production process, and sends the tag identification to the gateway device, wherein the RFID tag is set on the paper receipt clamp that holds the paper receipt.

[0087] Before or after holding the paper receipt, the item production personnel places the paper receipt holder within the sensing range of the first RFID reader / writer. The first RFID reader / writer reads the tag identifier of the RFID tag set in the paper receipt holder and sends the acquired tag identifier to the gateway device.

[0088] In step 330, the gateway device takes the time point when the order identifier and the label identifier are received as the first time point, establishes a corresponding relationship between the order identifier and the label identifier, and sends the corresponding relationship and the first time point to the server.

[0089] The gateway device receives the order identifier and the tag identifier. If the time interval between receiving the order identifier and the tag identifier is within a preset interval threshold, a correspondence between the order identifier and the tag identifier is established, and the time point when the order identifier and the tag identifier are received is taken as the first time point, that is, the time point of the last received identifier (order identifier or tag identifier) ​​is taken as the first time point. For example, the order identifier is first received at 11:30:30, and the tag identifier is received at 11:30:32, then 11:30:32 is taken as the first time point.

[0090] In step 340, the server receives the correspondence between the order identifier and the label identifier, and uses the first time point as the start time point of the production start link corresponding to the order identifier.

[0091] After the server receives the correspondence between the order ID and the label ID and the first time point, it can save the correspondence between the order ID and the label ID before the production of the item corresponding to the order ID is completed, thereby associating the order ID in the paper receipt and the label ID in the RFID tag during the production process of the item, and using the first time point as the starting time point of the production start link corresponding to the order ID to track the time when the order ID starts production.

[0092] Step 350: When the paper receipt is transferred to the current production link, the second RFID reader reads the tag identifier of the RFID tag and sends the tag identifier to the gateway device.

[0093] A second RFID reader is set up in each production link of the item. When the paper receipt flows to the current production link, the item production personnel only need to place the paper receipt clamp holding the paper receipt within the sensing range of the second RFID reader set up in the corresponding area of ​​the current production link. The second RFID reader can then read the label identification in the RFID tag on the paper receipt clamp and send the label identification to the gateway device 14.

[0094] In step 360, the gateway device uses the time point at which the tag identifier sent by the second RFID reader is received as the second time point, and sends the tag identifier, the reader identifier of the second RFID reader and the second time point to the server.

[0095] When the gateway device receives the tag identifier sent by the second RFID reader, it can obtain the reader identifier of the second RFID reader, and use the time point of receiving the tag identifier as the second time point, and send the tag identifier, reader identifier and the second time point to the server.

[0096] Step 370, the server determines the current production link corresponding to the order identifier based on the pre-established correspondence between the reader identifier and the production link, and the correspondence between the order identifier and the tag identifier, and uses the second time point as the start time point of the current production link.

[0097] The server determines the order ID corresponding to the just-received tag ID based on the correspondence between the tag ID and the order ID, and determines the current production link corresponding to the just-received reader ID based on the pre-established correspondence between the reader ID and the production link, thereby obtaining the current production link corresponding to the order ID, and taking the second time point as the starting time point of the current production link, thereby realizing the tracking of the production process of the items in the order and obtaining the starting time point of each production link.

[0098] In one embodiment of the present application, it also includes:

[0099] After determining the current production link corresponding to the order identifier, the server obtains prompt information corresponding to the current production link from the order corresponding to the order identifier, and sends the prompt information to the gateway device, wherein the prompt information includes user demand information;

[0100] The gateway device sends the prompt information to the display device corresponding to the current production link;

[0101] The display device displays prompt information corresponding to the current production link.

[0102] A display device can also be set in the area corresponding to the item production link, and the prompt information corresponding to the current production link can be displayed through the display device. The prompt information can be user demand information, such as information such as precautions in the current production link, or information about items to be prepared in the current production link. Some information that needs to be emphasized (such as remarks in an order, or other error-prone information) can be highlighted. For example, in the cooking link, highlight the user's taste requirements, or, in the packaging link, highlight information related to tableware, etc. Displaying prompt information on a display device solves the problem in the prior art that paper receipts cannot provide special prompts for information in the order, which can improve the operating efficiency of item production personnel and reduce the probability of errors, thereby reducing the requirements for the experience and cognitive level of item production personnel and reducing labor costs.

[0103] In one embodiment of the present application, it also includes: when the server determines that the current production link corresponding to the order identifier is the production termination link, the corresponding relationship between the order identifier and the label identifier is released. When the server determines that the current production link corresponding to the order identifier is the production termination link, that is, the items in the order have been produced, the corresponding relationship between the order identifier and the label identifier is released, so that the paper receipt clamp can be used again to clamp paper receipts of other orders to achieve reuse. The second RFID reader / writer set in the corresponding area of ​​the production termination link can be set in the storage box of the paper receipt clamp, and the storage box is used to store the paper receipt clamp. After the production of the item is completed, the item production personnel can take down the paper receipt clamp holding the paper receipt and put it into the storage box, so that the second RFID reader / writer in the storage box can read the label identification of the RFID tag in the paper receipt clamp.

[0104] In one embodiment of the present application, it also includes: the server determines the consumption time corresponding to the previous production link or the production start link based on the start time point of the current production link and the start time point of the previous production link or the start time point of the production start link, and predicts the remaining preparation time required for the item corresponding to the order identifier based on the total consumption time of the current production link and historical orders, and schedules delivery resources according to the remaining preparation time to deliver the item corresponding to the order identifier.

[0105] After determining the start time points of two adjacent production links of an order, the server can subtract the start time point of the latter production link from the start time point of the previous production link to obtain the consumption time of the previous production link. For example, after obtaining the first time point at the production start link and the second time point of the first production link, the server can subtract the first time point from the second time point to obtain the time consumed from the start of production to the first production link, that is, the consumption time of the order in the production start link. After determining the start time point of the current production link and the consumption time of the previous production link or the production start link, combined with the total consumption time of historical orders, the remaining preparation time required for the item corresponding to the order identifier can be predicted. For example, the total consumption time of the same item in the historical order as the order identifier is 10 minutes, and the consumption time of the order identifier in the previous production links is 5 minutes, then the remaining preparation time is 5 minutes. After determining the remaining preparation time of the item corresponding to the order identifier, the delivery resources can be dispatched according to the remaining preparation time to collect the item corresponding to the order identifier from the merchant for delivery. For example, when the remaining preparation time is 5 minutes, the delivery resources can be dispatched to arrive at the merchant within 5 minutes, thereby avoiding the delivery resources from waiting for a long time at the merchant, thereby improving the delivery efficiency.

[0106] The item production tracking method provided by the embodiment of the present application sets an RFID tag on a paper receipt holder, and a scanner scans and obtains the order identifier in the paper receipt at the starting stage of item production. The first RFID reader reads the tag identifier in the RFID tag at the starting stage of item production, and a gateway device establishes a corresponding relationship between the order identifier and the tag identifier, and sends the corresponding relationship and the corresponding first time point to the server. The server receives the corresponding relationship between the order identifier and the tag identifier, and uses the first time point as the starting time point of the production starting stage corresponding to the order identifier. During the circulation of the paper receipt, the second RFID reader set in the corresponding area of ​​the item production stage can obtain the RFID tag identifier. The gateway device sends the tag identification, the reader identification of the second RFID reader and the second time point to the server. The server determines the current production link corresponding to the order identification according to the pre-established correspondence between the reader identification and the production link and the correspondence between the order identification and the tag identification, and uses the second time point as the starting time point of the current production link. Therefore, in the circulation of paper receipts, the tracking of the production links of items in the order can be achieved through the RFID tag set on the paper receipt clamp, the scanner and the first RFID reader set at the starting link of the item production, the second RFID reader set in the corresponding area of ​​the item production link, the gateway device and the server.
