Description

Technical Field

[0001] The present invention relates to the technical field of safety inspections, and particularly to an inspection method and system for a catering kitchen based on NFC technology. Background Art

[0002] Most of the existing inspections of catering kitchens adopt a regular and fixed-point inspection method, arranging inspection personnel to check each inspection point one by one and reporting in paper records. This easily leads to various problems such as key inspection points being missed, manual records being easily lost or tampered with, resulting in untimely reporting of inspection results, and differences in the understanding of inspection items by different inspection personnel leading to non-standard operations. In addition, the response to emergency events generated in the catering kitchen lags, and the confusion of personnel permissions easily leads to unclear responsibility division. Summary of the Invention

[0003] In view of the above technical problems raised in the background art, the present invention provides an inspection method and system for a catering kitchen based on NFC technology.

[0004] The present invention solves the above technical problems through the following technical solutions: In a first aspect, the present invention provides an inspection method for a catering kitchen based on NFC technology. The inspection method includes: Step S1: Divide the catering kitchen into several areas to be inspected, set several inspection points in each area to be inspected, deploy NFC tags at each inspection point, and bind a unique code and associated inspection items to the NFC tags; Step S2: The administrator configures the inspection plan through the background management module of the inspection system, assigns exclusive inspection items to inspection personnel of different positions, and the inspection system generates a list of inspection tasks including the inspection validity period, path, inspection frequency, and responsible person; wherein, the path is the priority order of inspection of the inspection points; Step S3: The inspection personnel log in to the mobile terminal and verify their position permissions. After arriving at the inspection point, they touch the NFC tag, and only the inspection tasks corresponding to the inspection point within the position permissions are displayed on the mobile terminal. The inspection personnel check item by item according to the list and upload the data to the inspection system; Step S4: The inspection system triggers a hierarchical exception alarm for the abnormal data in the uploaded data and generates a rectification work order until it is normal; Step S5: Based on historical inspection data, an inspection summary report is output.

[0021] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the described embodiments.

[0022] Embodiment 1 As Figure 1 shown, this embodiment provides an inspection method for the catering kitchen based on NFC technology. The inspection method includes: Step S1: Divide the catering kitchen into several areas to be inspected. Set several inspection points in each area to be inspected, deploy NFC tags at each inspection point, and bind a unique number and associated inspection items to the NFC tags. In this embodiment, the areas to be inspected include the food storage area, the cooking and processing area, and the cleaning and disinfection area; the associated inspection items for the food storage area include refrigeration temperature, shelf life record, and stacking height; the associated inspection items for the cooking and processing area include stove cleanliness, range hood status, and fire extinguisher pressure value; the associated inspection items for the cleaning and disinfection area include dishwasher water temperature, disinfection cabinet airtightness, and garbage disposal timeliness.

[0023] Step S2: The administrator configures the inspection plan through the background management module of the inspection system, assigns exclusive inspection items to inspectors of different positions, and the inspection system generates a list of inspection tasks including inspection validity period, path, execution frequency, and responsible person; where the path is the priority order of inspection points for inspection. In this embodiment, assigning exclusive inspection items to inspectors of different positions means that, for example, this embodiment includes three positions, namely the head chef, the cleaning administrator, and the safety officer. Then their respective position authorities should be that the head chef needs to inspect the status of cooking equipment, dish production specifications, etc.; the cleaning administrator needs to inspect disinfection records, garbage disposal timeliness, etc.; the safety officer needs to inspect gas valves, fire fighting equipment, circuit safety, etc. In addition, high-risk inspection items (such as gas inspection) are restricted to be operated only by the safety officer; while for basic inspection items (such as floor cleaning, etc.), cross-role multiple-person review is allowed.

[0024] Step S3: The inspector logs in to the mobile terminal and verifies the position authority. After arriving at the inspection point, touch the NFC tag. Only the inspection tasks corresponding to the inspection point within the position authority are displayed on the mobile terminal, and the inspector checks item by item according to the list and uploads the data to the inspection system. In this embodiment, the unique number bound to the NFC tag can be used to detect whether the inspector has inspected the inspection point and whether the inspection point is correct. As Figure 3 shown, the inspector holds a mobile terminal with NFC identification, logs in to the personal information to check whether the inspector himself / herself has an inspection plan for the day. If there is an inspection plan, select the inspection point (taking the stove in the cooking area as an example of the inspection point), select the inspection point of the stove, and view the specific location of the point; hold the mobile terminal and arrive at the stove point, bring the mobile terminal close to the NFC tag at the stove point, identify the code of the NFC tag, and verify whether the NFC code of the current stove point is consistent with the identified NFC code. If they are consistent, load the inspection items corresponding to the stove inspection point; if they are inconsistent, prompt that it is not the stove point that needs to be inspected currently.

[0025] As an alternative embodiment, in step S3, encrypted geographical location information corresponding to the inspection points is embedded in each NFC tag. When the mobile terminal touches the NFC tag, it automatically decrypts and verifies the validity of the inspection point. If the NFC tag is not touched, the inspection task of the inspection point cannot be loaded.

[0026] As an alternative embodiment, in step S3, verifying the position authority specifically further includes: confirming the position of the inspection personnel through biometric identification of the mobile terminal or scanning the work card. Further, if the inspection personnel attempt to access inspection items outside their own position authority, the inspection system will record violation logs and notify the background administrator, ensuring the division of inspection personnel authority and avoiding unclear responsibilities caused by chaotic authority division.

[0027] In this embodiment, uploading data to the inspection system specifically further includes: forcibly requiring photos to be taken and uploaded for key inspection items at key inspection points, and the photos carry a timestamp, encrypted geographical location information, the ID bound to the inspection point, and the signature of the inspection personnel. In addition, when the inspection of high-risk inspection points (such as gas valves) is completed, it is necessary to verify biometric information again to confirm the identity of the operator.

[0028] Step S4: The inspection system triggers hierarchical abnormal alarms for abnormal data in the uploaded data and generates rectification work orders until normal.

[0029] As an alternative embodiment, as Figure 2 shown, the hierarchical abnormal alarm triggered by the abnormal data in step S4 includes: Judging whether the alarm is a high-risk alarm for gas. If it is determined to be yes, the inspection system immediately executes the following steps: Step S41: Trigger the gas alarm and close the gas intelligent valve; Step S42: Synchronously turn on the exhaust system and push an evacuation notice to the mobile terminals of all inspection personnel; Step S43: Send an emergency help message including the location of the catering kitchen to the fire department.

[0030] If it is determined to be no, it is processed in the hierarchical order according to the level of the abnormal alarm; the hierarchical order includes a first-level alarm and a second-level alarm: the first-level alarm is to notify the responsible person of the alarm in the form of message push and SMS and respond within a predetermined time; the second-level alarm is that if it has not been processed for multiple times, the alarm is sent to the background of the inspection system for escalation.

[0031] Step S5: Output an inspection summary report based on historical inspection data.

[0032] In this embodiment, a patrol inspection method for the catering kitchen based on NFC technology is provided. The patrol inspection method of the present invention deploys NFC tags at the patrol inspection points, encrypts the geographical locations of the NFC tags, and adds timestamps to the data uploaded by taking pictures. The dual verification ensures that the patrol inspection personnel must arrive at the patrol inspection points to execute the patrol inspection tasks, rejecting false patrol inspections; then, through a hierarchical alarm mechanism, a full closed-loop management from potential hazard discovery to equipment control is realized, improving the response speed of emergency events generated in the catering kitchen; then, through position verification permissions, the division of the patrol inspection personnel's permissions is guaranteed, avoiding unclear responsibilities caused by chaotic permission division; finally, the patrol inspection data is uploaded by the patrol inspection mobile terminal and processed and stored by the patrol inspection system, avoiding various problems such as missed patrol inspection points, untimely reporting of inspection results, non-standard operations, and untimely rectification, improving the patrol inspection work efficiency, saving time and effort.

[0034] The patrol inspection terminal module 12 is used to set up a mobile terminal equipped with an NFC reading and writing module and a data collection module. The mobile terminal is used to read NFC tags, retrieve the list of patrol inspection tasks, and upload data.

[0035] The background management module 13 is used to set various data in the patrol inspection system and analyze the data uploaded by the mobile terminal. As an optional embodiment, the background management module 13 includes: a patrol inspection plan configuration sub-module 131, a data analysis sub-module 132, an abnormal alarm sub-module 133, and a position permission management sub-module 134; The patrol inspection plan configuration sub-module 131 is used to generate a list of patrol inspection tasks including patrol inspection deadlines, paths, patrol inspection frequencies, and responsible persons.

[0036] The data analysis sub-module 132 is used to analyze the inspection data uploaded by the mobile terminal. In this embodiment, the data analysis sub-module 132 includes: a dynamic path planning unit 1321 and a real-time work order positioning unit 1322; the dynamic path planning unit 1321 is used to adjust the priority order of the inspection points according to the historical anomaly frequency and the peak dining period; the real-time work order positioning unit 1322 is used to automatically generate a rectification work order for the anomaly data uploaded by the mobile terminal and assign it to the responsible person, and track the processing status until it is normal.

[0037] The anomaly alarm sub-module 133 detects the anomaly data in the inspection data and triggers an anomaly alarm. In this embodiment, the processing is carried out in the hierarchical order according to the level of the anomaly warning; the hierarchical order includes a first-level warning and a second-level warning: the first-level warning is to notify the responsible person of the warning in the form of message push and SMS, and respond within a predetermined time; the second-level warning is that if it has not been processed for multiple times, the warning is sent to the background of the inspection system for escalation.

[0038] The position permission management sub-module 134 is used to set the inspection permissions of the inspection personnel in different positions, including the inspection scope, data viewing and inspection task assignment permissions. In this embodiment, the position permission management sub-module 134 also includes: a dynamic task allocation unit 1341 and a cross-position collaborative task unit 1342; the dynamic task allocation unit 1341 is used to automatically screen and issue the corresponding inspection items according to the position of the inspection personnel logging in to the mobile terminal; the cross-position collaborative task unit 1342 is used to when multiple different positions are required for joint inspection at one inspection point, the inspection system combines the inspection tasks and synchronizes the data to each mobile terminal.

[0039] The data analysis module 14 is used to generate a visual inspection summary report based on the historical inspection data.

[0040] The safety linkage control module 15 is used to connect the safety devices in the catering kitchen and automatically trigger the safety devices according to the anomaly warning level, where the safety devices include a gas alarm, a gas intelligent valve, an exhaust system, and a fire protection device.

[0041] In this embodiment, when the abnormal alarm is a high-risk gas alarm, the safety linkage control module 15 immediately executes the following: trigger the gas alarm, send a gas intelligent valve closing instruction, and force the closing after starting a countdown (such as 10 seconds); synchronously turn on the exhaust system and push an evacuation notice to the mobile terminals of all inspection personnel; preferentially use fire-fighting equipment, and if the status of the fire-fighting equipment is abnormal (such as insufficient pressure in the fire extinguisher), trigger an audible and visual alarm and send an emergency assistance message including the location of the catering kitchen to the fire department. Specifically, taking the gas inspection point in the cooking and processing area as an example, when the inspection personnel touch the NFC tag in the gas area, the mobile terminal displays the "gas valve inspection" task; when the mobile terminal sensor detects that the concentration exceeds the standard (>10% LEL), the mobile terminal forces the inspection personnel to take a photo and upload it; the background immediately triggers the following actions: send a closing instruction to the gas valve (to be executed after 10 seconds); turn on the exhaust system to the maximum power; push the alarm to the chef's mobile phone and synchronize it to the fire control room; the chef confirms whether it is a false alarm within the countdown and can choose to cancel the closing instruction; the system records the whole process data and generates a compliance report for future reference.

[0042] In this embodiment, an inspection system for a catering kitchen based on NFC technology is provided. The inspection system for a catering kitchen based on NFC technology is implemented on the basis of the inspection method for a catering kitchen based on NFC technology in Embodiment 1. By deploying NFC tags at inspection points, encrypting the geographical locations of the NFC tags, and adding timestamps to the data uploaded during photo-taking, double verification ensures that inspection personnel must reach the inspection points before they can execute the inspection tasks, rejecting false inspections; then, through a hierarchical alarm mechanism, a full closed-loop management from hidden danger discovery to equipment control is achieved, improving the response speed of emergency events generated in the catering kitchen; then, through position verification permissions, the division of inspection personnel permissions is guaranteed, avoiding unclear responsibilities caused by chaotic permission division; finally, by uploading inspection data through the inspection mobile terminal and processing and storing the inspection data by the inspection system, various problems such as missed inspection points, untimely reporting of inspection results, non-standard operations, and untimely rectification are avoided, improving the inspection work efficiency and saving time and effort.
