Description

Technical Field

[0001] The present invention relates to the technical field of dining kitchen equipment, and in particular to a method for automatically receiving orders for dining kitchen equipment by simulating a POS printer. Background Art

[0002] In today's restaurant industry, order processing is a critical step in ensuring service efficiency and quality. Currently, common ordering methods include customers scanning a QR code to order through ordering systems like Meituan and Keruyun, or having waiters place orders at the front desk. After the order is placed, the order system's server A generates the order information and pushes it to the in-store cash register. The in-store cash register is connected to multiple POS receipt printers via network cables or Bluetooth. The front-of-house printer prints receipts for customers, while the in-store cash register prints separate receipts for different dishes on separate back-of-house printers. Chefs then prepare the dishes based on these receipts. This traditional order processing method has, to a certain extent, maintained the normal operation of the restaurant business and met the basic needs of daily restaurant operations.

[0003] However, with the increasing demand for intelligent catering, the existing process has become increasingly complex and inefficient when introducing automated order-taking smart kitchen appliances. First, each smart device manufacturer needs to deploy its own dedicated backend server, Server B, and establish an IoT connection with smart devices via the internet using protocols like MQTT. Server B also needs to register with the ordering system's Server A to receive push messages. This not only increases the device manufacturer's operating costs and technical difficulty, but also complicates and bloats the entire system architecture. Second, given the wide variety of ordering systems available on the market—besides well-known ones like Meituan and Keruyun, there are also numerous lesser-known mini-program-based custom ordering systems. Smart device manufacturers need to develop interfaces for each of these ordering systems to connect to them and receive push orders, significantly increasing development workload and time. Furthermore, access to these ordering systems often requires payment to the ordering system provider, further increasing the cost of implementing smart kitchen appliances for catering companies. These issues have severely hindered the widespread adoption and efficient promotion of smart kitchen appliances within the catering industry, making it difficult to meet the modern catering industry's demand for intelligent and convenient operations.

[0004] To this end, we provide a method for kitchen equipment to automatically receive orders by simulating a POS printer to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for automatically receiving orders by simulating a POS printer using restaurant kitchen equipment. By camouflaging the device protocol, configuring the cash register system binding, and coordinating a series of auxiliary mechanisms and closely coordinated operations between the various steps, the present invention solves the problems of the prior art in which restaurant kitchen equipment is complex to connect to the ordering system, poor compatibility between different ordering systems, high development costs, and high operating costs.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention provides a method for automatically receiving orders by simulating a POS printer using a dining kitchen device, comprising the following steps: Step a: Device protocol disguise and connection establishment: The intelligent dining kitchen device establishes a data connection with an in-store cash register via a network cable, Wi-Fi, or Bluetooth communication link. The intelligent dining kitchen device simulates the instruction set architecture of the POS protocol based on the device driver layer, and disguises its own hardware interface as a virtual peripheral that complies with the communication specifications of the POS receipt printer. When connected via a network cable or Wi-Fi, a listening socket is established on the TCP9100 port, and when connected via Bluetooth, a virtual serial port communication is established in accordance with the SPP protocol; Step b: Cash register system binding configuration: The printer management module built into the cash register operating system is used to logically bind the type of food to be produced by the intelligent device to the disguised virtual POS printer. The binding process includes setting a mapping relationship between dish classification and printer port in the cash register system background management interface, and supports dynamic binding rule configuration by matching dish name keywords through regular expressions; Step c: Order information transmission: The ordering system generates order information containing dish name, specifications, and cooking instructions, and pushes it to the cash register via an API interface or a message queue. The cash register's order processing module includes structured data in JSON format and a text instruction set for the POS protocol. Step d: Order Information Sorting: The cash register's order parsing engine extracts fields and matches rules based on preset binding rules. It encapsulates meal information that meets the smart device's processing requirements into a POS protocol print instruction stream, which is sent to the smart kitchen appliance's protocol parsing module via Socket or serial communication. Simultaneously, the front desk cash register receipt is sent to the physical POS printer. Step e: Instruction Parsing and Information Extraction: The smart kitchen appliance's protocol processing unit parses the received POS instruction stream line by line, identifies dish name fields, specification parameters, and cooking instructions using a regular expression matching algorithm, and stores the parsed structured data in the device's cache. Step f: Processing Execution and Status Feedback: The smart kitchen appliance's control system generates processing instructions based on the parsed dish information, drives the heating, stirring, and cutting actuators to complete the automatic production process, and upon completion, sends a status feedback packet containing the device ID, order number, and completion time to the cash register via a communication link. The feedback packet follows a custom JSON format protocol.

[0007] The present invention is further configured such that the smart kitchen appliance includes a heartbeat detection protocol in the monitoring mechanism of the TCP9100 port, and actively sends a link maintenance packet when no data is received for more than 30 seconds to prevent the NAT device from disconnecting.

[0008] The present invention is further configured such that the binding configuration of the cash register supports multi-level dish classification binding, different smart device port mappings can be set for different categories of staple food and beverages, and real-time modification of binding rules is supported and takes effect immediately.

[0009] The present invention is further configured such that the POS protocol parsing process includes a check code verification mechanism, which ensures the integrity of data transmission by calculating the CRC-8 check value of the instruction stream, thereby preventing garbled characters or loss of order information during transmission.

[0010] The present invention is further configured such that the information recognition module of the intelligent kitchen appliance supports a custom dish alias database, and can map the common name of "Iced American" to a standard dish name to improve recognition accuracy.

[0011] The present invention is further configured such that the order information pushed by the ordering system includes an order priority field, and the intelligent kitchen equipment adjusts the processing queue order according to the priority field to support a queue-jumping processing mechanism for expedited orders.

[0012] The present invention is further configured such that the Bluetooth connection between the smart kitchen appliance and the cash register uses an AES-128 encryption algorithm to encrypt the transmitted data to prevent the order information from being eavesdropped during the wireless transmission process.

[0013] The present invention is further configured such that the processing execution and status feedback include a dual-machine hot standby mechanism, and when a main device fails, the cash register automatically reroutes the order to the virtual printer port of the backup smart device.

[0014] The present invention is further configured such that the processing execution and status feedback also includes food consumption data, and the cash register automatically updates the raw material usage record in the inventory management system after receiving the feedback.

[0015] The present invention is further configured such that the smart kitchen appliance supports OTA firmware upgrades, and when the POS protocol version is updated, the protocol parsing module of the appliance can be remotely updated through the management interface of the cash register.

[0016] The present invention has the following beneficial effects: 1. This invention has established a complete and systematic order processing flow. From establishing the connection between the equipment and the cash register, to the precise allocation of orders, to the accurate analysis and production of feedback, each link is closely linked, effectively solving the problems of low efficiency and prone to errors in traditional manual order delivery. By simulating the communication specifications of POS printers, it realizes the seamless connection between smart kitchen equipment and existing cash register systems, fully leveraging the advantages of smart devices, significantly improving the degree of automation of catering operations, and laying a solid foundation for efficient restaurant management and improved service quality.

[0025] Example 3 Application of intelligent cooking machine in Chinese fast food restaurant In a 24-hour Chinese fast food restaurant, multiple intelligent cooking machines were deployed to automatically prepare various Chinese food orders. The specific implementation process is as follows: Device protocol masquerading and connection establishment: The intelligent cooking machine establishes a data connection with the in-store cash register through a network cable. At the device driver layer, the intelligent cooking machine simulates the instruction set architecture of the POS protocol and disguises its hardware interface as a virtual peripheral that conforms to the communication specifications of a POS receipt printer. In the network configuration, the intelligent cooking machine creates a listening socket on TCP port 9100. The built-in heartbeat detection protocol will actively send a link keep-alive packet to the cash register when no data has been received for more than 30 seconds to maintain connection stability.

[0026] If a Bluetooth connection needs to be temporarily adopted due to network cabling issues, the intelligent cooking machine and the cash register will establish virtual serial port communication following the SPP protocol and simultaneously use the AES-128 encryption algorithm to encrypt the transmitted data to prevent the leakage of order information.

[0027] Cash register binding configuration: The cashier configures the intelligent cooking machine in the printer management module of the cash register operating system. In the background management interface of the cash register system, the Chinese dish categories (such as stir-fried dishes, stewed dishes) are logically bound to the virtual POS printer ports disguised by the intelligent cooking machine. By setting regular expressions, such as "stir-fry.*" to match all stir-fried dishes and "stew.*" to match stewed dishes, precise binding is achieved.

[0028] The cash register supports multi-level dish category binding. For example, cold dishes can be bound to other intelligent devices, and the binding rules can be modified in real time to meet the needs of the store to adjust dish offerings according to different time periods.

[0029] Order information transmission: When a customer places an order for dishes such as "Kung Pao Chicken, medium portion, slightly spicy" and "Braised Beef with Potatoes, large portion" in the ordering system, the ordering system generates order information containing dish names, specifications, and preparation notes fields in the form of JSON-formatted structured data and POS protocol text instruction sets, and pushes it to the order processing module of the cash register through the API interface. The order information includes an order priority field, and higher priorities are set for takeaway orders and orders during peak hours.

[0030] Order information sorting: After receiving the order data, the order parsing engine of the cash register, based on the preset binding rules, uses regular expression matching to determine that "Kung Pao Chicken" and "Braised Beef with Potatoes" fall within the processing scope of the intelligent cooking machine. It encapsulates the meal information into a POS protocol print instruction stream and sends it to the protocol parsing module of the intelligent cooking machine through Socket communication, while sending the front desk cash register list to the physical POS printer.

[0031] Instruction parsing and information extraction: The protocol processing unit of the intelligent cooking machine analyzes the received POS instruction stream line by line, uses the regular expression matching algorithm to identify information such as dish names, specifications, and cooking remarks, and stores the parsed structured data in the device buffer. The checksum is verified by calculating the CRC-8 checksum value to ensure data integrity.

[0032] The information recognition module of the intelligent cooking machine customizes the dish alias database. For example, it maps the common name "Three Delicacies" of "Sauteed Potato, Green Pepper and Eggplant" to the standard name to improve the recognition accuracy.

[0033] Processing execution and status feedback: The control system of the intelligent cooking machine generates processing instructions based on the parsed dish information, and drives the actuators such as the stir-frying device and the seasoning dispensing device to complete the dish making. After completion, it sends a status feedback packet containing the device ID, order number, completion time, and ingredient consumption data (such as the amount of chicken used, the amount of potatoes used, etc.) to the cash register, using a custom JSON format protocol.

[0034] During the processing, the intelligent cooking machine adjusts the processing queue according to the order priority, and urgent orders can be processed by cutting in line. The system has a dual-machine hot standby mechanism. When the main device fails, the cash register automatically routes the order to the standby intelligent cooking machine. After receiving the feedback, the cash register updates the raw material usage records in the inventory management system, and the store manager can perform OTA firmware upgrades on the intelligent cooking machine through the cash register management interface.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific embodiments described. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, so that those skilled in the art in the relevant technical field can well understand and utilize the present invention.
