Description

Technical Field

[0001] The present application relates to the technical field of grain and oil sample collection and management, and specifically to a grain and oil sample full-process management system based on RFID. Background Art

[0002] In recent years, people have paid more and more attention to the safety of grain and oil food, and the demand for testing grain and oil samples has also increased. The difficulty of managing samples to be tested in testing laboratories at all levels has also increased. Grain and oil samples are numerous and varied. The traceability of samples requires many links from collection, transportation, storage to inspection, and each link generates a large amount of information. At present, the collection and management of grain and oil samples mainly rely on manual operations and paper records. This method has many problems, such as record errors or omissions, sample loss, and chaotic management. In addition, the traceability of traditional recording methods is poor, and it is difficult to quickly and accurately obtain environmental information of samples in the collection and other links. In recent years, with the increasing demand for information management, some systems have introduced technologies such as barcode labels to realize the automation of management processes. However, barcode technology has disadvantages such as easy shedding, short reading distance, and susceptibility to contamination, which makes it difficult to meet the actual needs in the management of grain and oil samples.

The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0029] The terms such as "upper", "lower", "left", "right", "middle", etc. cited in this application are usually used to indicate the general relative position relationship for the purpose of intuitive understanding by referring to the drawings, and are not absolute limitations on the position relationship in the actual product.

[0030] See also Figure 1 The present application provides a full-process management system for grain and oil samples based on RFID, including RFID tags, information collection systems and intelligent management platforms; the information collection system includes tag reading and writing devices and information collection terminals, the tag reading and writing devices include handheld readers and fixed readers, and the information collection terminals include GPS modules, cameras and environmental sensors; the intelligent management platform includes authority management modules, information storage modules, information query modules, information output modules, monitoring and early warning modules and log systems.

[0031] Specifically, RFID tags are used to identify grain and oil samples. Each grain and oil sample is equipped with a unique RFID tag as the sample's identity to achieve unique traceability of sample information.

[0032] Furthermore, the RFID tag stores basic information of the sample, such as sample name, number, batch, sampling volume, sample type, collection time, collection location, collector, etc. The sample name, number, batch, sampling volume, collection time, location and collector information are written into the tag through a handheld RFID reader to ensure "one object, one code".

[0033] Furthermore, this application uses ultra-high frequency (UHF) RFID tags that comply with the ISO 18000-6C standard, support waterproof and oil-proof coatings, and are suitable for humid or greasy environments of grain and oil samples. Before sampling begins, RFID tags are first attached to sample containers such as sample bags and sample bottles. The sample bottles can be integrated with built-in high-temperature resistant RFID chips for collecting liquid samples. If the sample is packaged or transferred to a new container, the original label information is associated with the new label through the reader / writer to form a parent-child label relationship to keep the traceability chain intact.

[0034] Specifically, the information collection system includes a tag reading and writing device and an information collection terminal, which are used to read and write sample information and environmental information in the RFID tag, and transmit the sample data to the data storage system through the data transmission system. The system generally uses the RFID reading and writing device to quickly identify and update the tag information to ensure the accuracy of "one object, one code".

[0035] Among them, tag reading and writing devices include handheld readers and fixed readers. Fixed readers are RFID readers or channels installed in specific locations such as storage rooms and laboratories. Information collection terminals include GPS modules, cameras, environmental sensors and other equipment, which can record the geographical location, environmental parameters and sample images of the collection site, and upload them to the cloud platform in real time through wireless networks (4G / 5G).

[0036] Furthermore, during the sampling process, the handheld terminal uses an industrial-grade PDA device that integrates RFID reading and writing, GPS positioning, environmental sensors (temperature, humidity, light) and cameras, and supports 4G / 5G real-time data transmission. Information collection can also be automatically generated through handheld mobile terminals such as PDAs and tablets, and other relevant values ​​​​(such as temperature, humidity, weight, etc.) are entered. The handheld terminal is installed with collection software, which can be synchronized with the background database in real time or intermittently to ensure that the data is updated in time and can be viewed remotely.

[0037] Furthermore, the transport vehicle is equipped with an on-board reader and writer and a temperature and humidity sensor, which is powered by the on-board power supply, uploads the location and environmental data in real time, monitors the sample location and transport environment parameters, and updates the RFID tag status.

[0038] Furthermore, readers and writers are deployed at warehouse entrances and laboratory passages and integrated with antenna arrays to achieve batch tag scanning within a range of 1 to 3 meters. At the same time, they automatically record sample entry time, shelf location, storage environment parameters, and update RFID tag status.

[0039] Furthermore, during testing, an RFID reader is installed at the entrance of the laboratory to automatically identify samples and associate pre-processing tasks, testing tasks and experimental operators. After the experiment is completed, the samples are returned to the warehouse, the operators register the sample usage, and the system automatically calculates the remaining sample quantity and updates the RFID tag status.

[0040] Furthermore, sample and environmental information collection equipment are also deployed in the transportation, storage and detection links.

[0041] Furthermore, the transport vehicles are equipped with on-board RFID readers and GPS tracking modules to monitor the sample location and transport environment parameters in real time and update the RFID tag status.

[0042] Furthermore, fixed RFID readers are deployed at the warehouse entrance and shelves to automatically record the sample entry time, shelf location, storage environment parameters, and update the RFID tag status.

[0043] Furthermore, after the test, the samples are returned to the warehouse, the operator registers the sample usage, and the system automatically calculates the remaining sample quantity and updates the RFID tag status.

[0044] Specifically, the intelligent management platform is an information management and comprehensive control platform, which is developed based on Web or mobile App, and provides functions such as grain and oil sample information entry, grain and oil sample information query, statistical analysis, grain and oil sample in and out warehouse management, transportation and storage conditions recording, early warning and authority management.

[0045] The authority management module supports multi-level authority control and sets different user roles and authorities, such as administrator, operator, etc. Administrators can modify label information and formulate early warning rules, samplers can upload sample information, warehouse staff can only operate the in and out status, and laboratory technicians can view the sample data of their laboratories, etc., to ensure that different users can only access data and functions within their authority.

[0046] The information storage module is a unified database or server-side management system used to store in multiple dimensions sample information, personnel information, environmental information, event information, etc. collected in various links such as collection, storage, transportation and experiment, so as to achieve all-round information traceability.

[0047] Furthermore, personnel information includes collectors, custodians, experimenters, etc., environmental information includes temperature, humidity, light, etc., and event information includes collection events, warehousing events, outbound events, experimental events, etc.

[0048] Furthermore, the information storage module may use a relational database or a non-relational database, for example: a MySQL relational database (storing structured data such as sample information) and a MongoDB non-relational database (storing unstructured data such as logs and images).

[0049] Furthermore, the handheld terminal temporarily stores data in a local database when offline, and uploads it through incremental synchronization after the network is restored to avoid data loss.

[0050] The information query module can support multi-dimensional queries, and users can select data fields, sorting and filtering conditions (time, location, test results, etc.) as needed.

[0051] After receiving the data from the RFID terminal, the information output module performs analysis, comparison or statistics, and provides rich reports and charts to conduct multi-dimensional analysis of sample information, forming visual data analysis charts to provide data support for management decisions.

[0052] Furthermore, the information output module can generate various sample management reports to display the real-time status of samples, including inventory, sample status, test results, etc., such as "in stock", "in transit", "in testing", "in stock and tested", etc.

[0053] Furthermore, if the samples need to be transferred to laboratory testing or warehousing, the system can automatically assign tasks, notify personnel, and perform label identification and information verification as needed.

[0054] Furthermore, the sample management report supports export in PDF, Excel, Word and other formats, and provides visualization charts such as line charts, bar charts, pie charts, heat maps, radar charts, bubble charts, etc. For example, it can display the sample distribution by warehouse shelf location, or compare the pollutant indicators of different batches of grain and oil samples by time axis.

[0055] Furthermore, the information output module provides an API interface for other systems to call sample data. The output sample data supports batch export, supports multiple formats such as CSV, XML, JSON, and supports encrypted export to ensure data security.

[0056] Furthermore, a printer is included. After the grain and oil samples are inspected, the sample information is printed out as a circulation list through the printer.

[0057] The monitoring module is used to monitor the flow status of samples, including collection, storage, transportation and testing, to ensure the traceability of samples.

[0058] When an abnormality occurs during the sample circulation process (such as label damage, information loss, timeout, etc.), the system automatically issues an alarm and generates an error correction work order. The system monitors the storage environment and validity period of the sample in real time according to the set warning rules. Once an abnormal situation occurs, an early warning is immediately issued to remind management personnel to deal with it in time. If the sample test results exceed the standard or are abnormal during the detection process, the system will automatically trigger an early warning to remind relevant personnel to prevent non-compliant grain and oil from entering the market or affecting the reliability of subsequent testing.

[0059] Furthermore, notifications can be sent within the system, and multiple channels such as email and text messages are also supported.

[0060] The log system has an audit log recording function, which retains detailed operation records of samples (such as RFID reading time, location, operator, test results, etc.), thereby forming a traceability chain throughout the entire life cycle.

[0061] Furthermore, the intelligent management platform uses blockchain technology to ensure that data cannot be tampered with. Each operation record (such as tag writing, test result update) generates a block and is distributed and stored in the management node, the test agency node, and the regulatory agency node.

[0062] Furthermore, the audit log records the operation time, user, operation type, abnormal event alarm, etc. in detail.

[0063] The laboratory sample circulation and management links are analyzed, which are mainly divided into seven links: sampling, transportation, storage, collection, pre-treatment, testing, retention and disposal. Figure 2 Each link needs to generate corresponding information, including sample name, sample status, personnel, experimental content, time, location, etc. Therefore, RFID tags and database information should be able to cover key data in the entire process of tracking samples.

[0064] See also Figure 2 , the present application also provides a grain and oil sample full-process management system based on RFID, including the following processes:

[0065] Step 1: Sampling: The sampler enters the sample information, prints the label and sticks it on the sample container, and uses the PDA to scan the RFID label. The sample ID is automatically generated and bound to the GPS coordinates, the sample appearance is photographed, the environmental sensor records the temperature and humidity, and the data is uploaded to the database through an encrypted protocol.

[0066] Step 2: Transportation: The sample enters the transport vehicle and is automatically associated with the vehicle information. The on-board reader reads the status of all tags in the vehicle at regular intervals. If the environmental parameters exceed the limit, an alarm is triggered and relevant personnel are automatically notified.

[0067] Step 3: Storage: When samples enter the warehouse, the warehouse and shelf information are automatically associated. Environmental sensors read the status of all tags in the room at regular intervals. If environmental parameters exceed the limit, an alarm is triggered and relevant personnel are automatically notified.

[0068] Step 4: Testing: When the sample enters the laboratory after being taken by the experimenter, the channel reader automatically identifies the tag and associates the testing task to the management system. After the pre-processing and testing are completed, the test results are sent back to the tag through the API to update the sample status.

[0069] Compared with traditional barcodes or paper labels, RFID tags are not only rewritable, but also can quickly identify multiple samples wirelessly. The unique coding of RFID tags improves the reliability and anti-counterfeiting ability of identification, and reduces loss, confusion and statistical errors.

[0070] When the sample enters the next circulation link, the corresponding RFID identification facilities will automatically verify the sample identity, mark the entry and exit time and circulation record. The system can monitor the whereabouts and location of the collected samples in real time to prevent sample loss, mistaking or use of wrong samples.

[0071] The physical and chemical properties and composition changes of grain and oil samples are greatly affected by environmental factors such as temperature, humidity, light, and cleanliness. The standardization of operators in each link and the status of testing equipment also have a great impact on the quality and safety inspection results of grain and oil samples. The traceability of information on the entire life cycle of grain and oil samples can improve the accuracy and reliability of test results, and combine environmental factors to identify abnormal results and trace the root causes of problems, and can also provide important support for quality management, risk warning, scientific research, etc.

[0072] The RFID-based grain and oil sample full-process management system provided in this application realizes the full-process automation and digital management of grain and oil sample collection, storage, transportation and testing through the combination of RFID tags and information management platforms. It can monitor the status and environmental information of samples in real time, provide early warning functions, and generate management reports to improve the efficiency and accuracy of sample management and ensure the traceability of samples. It is suitable for the field of grain and oil quality testing.

[0073] The present application provides an RFID-based full-process management system for grain and oil samples. Grain and oil sample management realizes digital management of the entire life cycle of grain and oil samples from collection to testing through the fusion of RFID and multi-source data, greatly improving the efficiency of sample traceability and abnormal event handling.

[0074] Compared with the prior art, this application has at least the following beneficial effects:

[0075] 1. This application is based on further analysis and research on existing technical problems. It records sample information through sample labels and efficiently enters the system, improves the automation level of sample management, and realizes automatic data recording of the entire sample management process.
