Let “trustworthy” rooted in consumers
——The retrospective application of melon in Balibagai, Altay, Xinjiang
Internet of Things Technology Research Center, Xinjiang Uygur Autonomous Region Institute of Standardization
The construction of the Internet of Things traceability system has strongly promoted the rapid development of Altay’s characteristic melon industry, and the characteristic traditional melon of Balibagai Township has gradually moved from street stall consumption to technology, marketization, and scale.
Since 2007, Xinjiang has used the GS1 system based on commodity barcodes to carry out research and practice on the traceability and traceability of agricultural product supply chains. Up to now, Xinjiang has achieved Turpan cantaloupe and grapes, Piyaman sweet pomegranate in Pishan County, thin-skinned walnuts and Yudu red dates in Hotan County, Hongliu Dayun in Yutian County, Andihe melon in Minfeng County, and Shufu County in Kashgar. Kashgar red dates, “Muyage” apricots, pomegranates, Jiashi melons in Jiashi County, Changji “Tianyu honey” melons, Altay “Bali Bagai” melons, etc., involving more than ten products in five prefectures. .
In 2013, based on the original “fruit and vegetable traceability system”, it further established and completed the “dairy product traceability system”, “aquatic product traceability system”, “livestock and poultry meat traceability system”, “food processing” and other subsystems, providing a deep traceability for Xinjiang. Development laid the foundation.
system structure
The Bali Bagai traceability system takes an enterprise integrating planting, processing, packaging, warehousing and transportation as the basic unit for management and configuration. Farmers, plots and products are the basic elements of this enterprise. Before listing, the local quality and technical supervision department will conduct product inspection on them. The products that pass the inspection will be put on the market after using the traceability code in the packaging process. The sales channels of the products include wholesale markets, supermarkets, farmers markets, etc. Products are not allowed to affix traceability marks. The traceability information forms a closed loop in the internal circulation and update of the enterprise, and is stored in the background database of the traceability system, which ensures the validity and credibility of the traceability information. The carelessness of the personnel makes the wrong information enter the traceability information database, which ensures the accuracy of the traceability information.
The traceability system consists of three subsystems: enterprise management, system management, and product traceability. The main functions are shown in Figure 1.
Figure 1 Traceability system architecture and functions
business management
In this subsystem, in addition to the inspection information entered and reviewed by the local quality supervision department, other traceability-related information is entered and reviewed by the enterprise itself. The information maintained by the system mainly includes company profile, qualification, honor information, company department, employee information, product introduction, variety, grade information, plot configuration information, basic information of farmers, field planting management information, rough processing information, Testing information, packaging information, warehousing information, transportation and sales information, etc., as well as maintenance of pesticide information, fertilizer information and auxiliary material information. In the traceability management module, the system can automatically generate traceability codes according to the manufacturer’s identification code, product code, packaging material, packaging date and packaging quantity.
System Management
This subsystem mainly completes enterprise registration, deletion, information maintenance of enterprise-level administrators, operators and reviewers, and management of roles and permissions.
In this system, users are subdivided into system administrators, enterprise administrators, enterprise auditors, enterprise operators, and regional query users.
System administrator: The system administrator can assign the registration code of the enterprise, manage all users, roles and permissions, view all related data, and decide whether to deactivate the enterprise user, and can delete all or part of the data of the enterprise user.
Enterprise administrator: The enterprise administrator manages enterprise auditors and enterprise operators, divides roles, sets permissions, sets data auditing mode, and performs data auditing operations on data to be audited.
Enterprise Auditor: In addition to the operation authority of the enterprise operator, the enterprise auditor also has the same audit data authority as the enterprise administrator.
Enterprise operator: The enterprise operator can only edit the content of the enterprise management system module.
Regional query user: The regional query user authority is assigned by the system administrator, and can query relevant statistical information such as enterprises, products and traceable quantities in the region.
Product traceability
In the Xinjiang food quality and safety traceability system, we summarize the data of each production enterprise and establish a unified traceability basic database. The end user sends a traceability code query request through the product traceability subsystem, and the qualified traceability code is decoded. The traceability database extracts product-related information and feeds it back to the client, and if the verification fails, it will feed back the prompt “The traceability code is incorrect”. The methods of traceability are divided into website traceability, supermarket terminal traceability, SMS traceability, etc.
At the end of 2010, the China Article Numbering Center proposed the idea of integrating the traceability information of various regional platforms, establishing and improving the national food safety traceability platform, and required to connect the local food traceability with the national food safety traceability platform. For this reason, Xinjiang used Web services technology to develop traceability. The information query interface realizes the traceability of Xinjiang food on the national traceability platform. Its query process is shown in Figure 2.
Figure 2 Traceability information query process
When a user initiates a Xinjiang food query request on the national food safety traceability platform, the national food safety traceability platform forwards the traceability code to the Xinjiang food traceability data interface. After decoding the traceability code, the product-related information is extracted from the traceability database and converted into A standard XML file, the XML file is returned to the national data platform after processing and returned to the browser of the user terminal in the form of a web page.
coding design
The traceability system is based on the GS1 system (Global Unified Coding and Identification System), selects the GS1-128 barcode as the data carrier, and uses the corresponding application identifier to identify the agricultural products added to the traceability system. The coding structure is shown in Table 1.
Table 1 Coding Structure Diagram
Among them, AI is the application identifier, and the application identifier is 01, indicating that the subsequent data segment is the Global Trade Item Number (GTIN). An application identifier of 13 indicates that the subsequent data segment is the packaging date, and an application identifier of 21 indicates that the subsequent data segment is a serial number. The indicator N1 uses 0 to 8 to identify quantitative packaging, and 9 to identify variable packaging, which ensures the uniqueness of individual identification of products of different grades and specifications, and meets the requirements of Xinjiang to join the traceability system of agricultural products. Figure 3 is the traceability barcode identification formed by a cantaloupe planting enterprise harvested on June 20, 2012:
Figure 3 Cantaloupe traceability barcode identification
In Figure 3, the indicator 9 indicates that the packaging specification of the cantaloupe is a variable (the weight of each cantaloupe is different), and “69412345” in the GTIN is the manufacturer’s identification code (8 digits) assigned to the cantaloupe planting enterprise by the China Article Numbering Center. The 4-digit “0001” after the manufacturer’s identification code is the product code allocated by the company for the super-class Golden Dragon cantaloupe variety, and the 1-digit “1” after the commodity item code is the verification code generated by the manufacturer’s identification code and the product code.
System operation effect
Balibagai Township successfully held the launching ceremony of the first quality and safety information traceability system in the Altay region in August 2012, and local leaders led the cooperative members to Beijing, Shanghai and other places to “run the market”. The whole process of inspection and sales is effectively linked, and the guarantee of safe consumption is significantly improved. After the melons with traceable codes entered high-end consumer markets such as Beijing, Shanghai, and Guangdong, their market popularity rapidly increased, forming a new Xinjiang melon brand. The first-class melon has increased from 5 yuan/kg to 12 yuan/kg. The products of Jinhe Melon Cooperative with the Bali Bagai melon traceability code have been favored by Beijing citizens. In 2012, a total of 26,000 tons of melons were sold, and the sales revenue exceeded 150 million yuan.
The construction of the Internet of Things traceability system has strongly promoted the rapid development of Altay’s characteristic melon industry, and the characteristic traditional melon of Balibagai Township has gradually moved from street stall consumption to technology, marketization, and scale. At the end of 2012, Balibagai Township Jinhe Melon Cooperative signed an order of 100 million yuan with Beijing Shijingshan District Commercial Committee, and sold 10,000 tons of melons through six supermarkets including Beijing Walmart and Yonghui. In 2013, a total of 24,700 mu of melons were planted in the township, with a traceable area of 5,000 mu of melons, and 10,000 tons of fine melons were sold to the high-end market in Beijing. According to statistics, the sales volume of melons in the township is expected to exceed 40,000 tons in 2014, and the sales revenue is expected to reach 200 million yuan, driving the per capita income of the township to increase by more than 4,000 yuan.
