Research on milk powder production and sales management system based on Beidou positioning

: Food safety is a major issue related to people's livelihood. In recent years, food safety incidents have emerged in China, and it is urgent to solve the problems in the field of food safety. Food safety traceability is an important means to ensure food safety. At present, BeiDou positioning system has not been widely used in food traceability, and the demand for dynamic food traceability has not been solved. To this end, the paper introduces the application of Beidou positioning technology to milk powder traceability supervision, combined with QR code scanning technology, to design a system that can be dynamically supervised. The product is based on the Beidou positioning system, which mainly includes a low-power Beidou positioning device terminal and a cloud server. The BeiDou locator attached to the bottom of the lid is the main device for all services to be realized, and the current location information of the device is obtained regularly when it is working. Combined with the two-dimensional code technology, it facilitates information entry and reading, and establishes a complete traceability supervision system, including an APP client, which facilitates users to inquire various information about the products. The information of traceability has openness and transparency, data immutability and traceability, so that consumers and food regulatory authorities can know all the information of milk powder from production to sales, and it is convenient to manage and monitor the whole process from production to sales, so that users can consume with confidence.


Project Background
China's economy is developing rapidly, the per capita wage level and other aspects of a larger replacement, resulting in a very important consumer power, and in the milk powder market has shown the rapid development of mid-range products, but the rapid development has also brought unstable factors to the "melamine incident" as the representative of the infant milk powder The melamine incident has had a huge negative impact on the trust in the safety of domestic infant formula. Although Chinese dairy enterprises, the government and society have made continuous efforts, the trust in the safety of domestic infant formula has not yet been restored. According to the data released by the State Administration of Market Regulation, the passing rate of infant formula sampling in 2020 reached 99.89%, but China imported 335,000 tons of infant formula, due to frequent safety problems, people are very dependent on imported milk powder, and online shopping as a popular shopping method in cash society, because of better portability and cheaper than physical stores are very popular among consumers, and in recent years, there is a large number of domestic milk powder posing as "baby formula". In recent years, a large number of domestic milk powder posing as "foreign brands" has emerged frequently, and illegal businesses sell counterfeit goods for profit to generate safety and quality problems that are difficult to locate at the source. However, the traditional traceability technology is susceptible to human tampering and centralization, and cannot guarantee data security. The double guarantee of using Beidou positioning module with indexed traceability code for dynamic supervision ensures that each bucket of milk powder has unique information and guarantees the authenticity of traceability data.

Project Introduction
Using the ultra-low power miniaturized Beidou positioning module to measure the distance between the known satellite and the receiver, and calculate the specific location through the computer, the spatial distance rear rendezvous method is adopted, together with the QR code as the unique cited traceability code, so that users can directly browse the traceability information flow of milk powder from the origin of milk to the whole sales process through the special traceability channel of the APP client, and obtain the traceability information flow from production to The source of raw materials, production information, logistics information, etc. from production to sales 2. Traceability system industry and based on the analysis of applications within the market

Industry Analysis
The traditional traceability system has some problems.
1) The supply chain system information standards are not uniform and the data are not connected.
2) Food information is not open and transparent, leading to mutual trust issues between the two parties.
3) The core data of the traceability system can be easily tampered with.
4) The traditional traceability system is fragmented, making it difficult to identify the responsible parties for food problems.
5) The system is heavily centralized, and the authenticity of information cannot be verified.

The traceability system based on BeiDou positioning system:
(1) The production and logistics information of commodities is made public through low-powered BeiDou positioning equipment, which can dynamically supervise the products, so that both sides of the information can get the real information of commodities in real time.
(2) The dual guarantee of Beidou positioning system combined with QR code technology prevents counterfeit products and has anti-counterfeiting function. (1) The state launches corresponding intra-industry guidelines, unifies industry standards, increases public credibility of the traceability system, and builds a true and efficient traceability system.

Market prospect analysis
(2) The traceability system is more oriented to daily consumer goods and will focus more on anti-counterfeiting of equipment and consumables and anti-counterfeiting of upstream channels.
(3) The app developed by the anti-counterfeiting platform itself needs to maintain sufficient interaction with customers, enhance attractiveness and form user stickiness.
(4) The government platform is affected by a variety of factors and progress is slow, while the enterprise platform is small in volume, relatively focused and has a variety of modes, and the complementary intermingling of the two types of platforms is an important way to promote the continuous and healthy development of the traceability system. The Beidou-3 global satellite navigation system marks the international leading level of China's satellite navigation and lays the material and technical foundation for the marketization, industrialization and internationalization of the Beidou system, and the Beidou industrialization and industrial Beidou empowerment promoted by the state are the focus of the implementation of the Beidou strategy during the 14th Five-Year Plan period, in which the traceability system profits. The industry certification of the Beidou system can do justice to the security of the traceability system, integrate the technology with the market, and improve the security of the traceability system.

Milk powder sales management system function overview
Five functions of the milk powder sales management system: 1). The product is based on Beidou positioning system, mainly including low-power Beidou positioning equipment, terminal and cloud server. The BeiDou locator attached to the bottom of the lid is the main device for all services to be realized, and the current location information of the device is obtained at regular intervals during its work, and if the location remains unchanged for a long time, it enters the hibernation mode. When the quality inspection department detects a substandard product or a consumer report can be immediately located, find the same batch of products and immediately recall or detain. At the same time can be traced to the specific production address and milk source address, the production enterprises to deal with the supervision.
2). Combined with the QR code technology, it is convenient to enter and read the complete information of milk powder from production to sale, and also prevent the appearance of counterfeit and shoddy products with anticounterfeiting function. After the milk powder passes through the production line, the QR code is printed on the milk powder cans, and consumers can get the corresponding milk powder production address, production time, production line, quality inspector and the corresponding Beidou chip serial number and other information in time by scanning the QR code.
3). The milk powder is shipped from the factory to open the positioning mode, and the positioning information is sent every other day and stored in the background database. If the address information remains unchanged for three consecutive days, the chip enters the sleep mode and starts to reposition after the acceleration is detected. 4). The database of the system can store two kinds of information. One is the basic information of the milk powder, and the other is the location information of the milk powder, both of which are linked by the serial number of the Beidou chip. The basic information of the milk powder has the serial number of the corresponding Beidou chip, so if you want to know the address information of the milk powder, you just need to call up the location information of the corresponding piece of Beidou chip. 5). this complete set of traceability supervision system, including APP client, users can log into the APP to scan the code to check the information of milk powder, but also a key to report, the regulatory department will immediately investigate after receiving the reported information, so that the supervision is more convenient and rapid, but also allows milk powder enterprises to gain credibility.

H. Regular inspection and evaluation of system effect: Regularly inspect and evaluate the positioning system, find problems and improve it in time to improve the system effect and management level.

Market risk
Market risk is the entrepreneurial risk resulting from the possibility of loss and uncertainty of profitability for a startup business to conduct economic activities. The main market risk of the BeiDou location-based milk powder production and sales management system is that other traceability platform service providers in the market have better services and more inside market information to launch stronger sales strategies or play price wars to capture market share.
Market risk prevention countermeasures: adhere to the market-oriented business philosophy, develop the correct marketing concept and marketing strategy. Strengthen marketing management, do a good job in marketing and product after-sales service, and enhance customer loyalty. Pay more attention to market trends in the same industry to provide basic guidance for the company to develop market decisions.

Managing risk
The milk powder production and sales management system based on Beidou positioning is mainly due to the traceability service provided by the platform agent selling milk powder products from other suppliers. Milk powder sales are an important area involving food safety and must comply with relevant regulations and policies. To ensure that the products sold meet the relevant standards to ensure the health and safety of consumers. The quality of the products selected is not up to standard may cause certain trouble to customers, thus affecting their trust in this milk powder production and sales management system and affecting the Company's normal business operations. Management risk prevention countermeasures: strengthen the screening of suppliers, ensure that the products of cooperative enterprises are legal and compliant, and carefully audit the production information of suppliers to avoid falsification.

Legal risks
Legal risk is the risk of breaking the law due to lack of legal knowledge or other reasons in the business activities of the enterprise.
The sale of milk powder involves national food safety regulations, so system development requires strict compliance with relevant laws and regulations to ensure that the products meet the relevant standards and regulations, or else you may be held legally responsible.
Legal risk prevention countermeasures: carefully study and understand the relevant legal provisions to avoid the risk of violations.

Technical Risks
Technology risk is the uncertainty of gains and losses due to the uncertainty of the technology or collection of technologies applied or proposed by science and technology and the uncertainty in the process of combining technology with other technological activities. The uncertainty of technology includes both the uncertainty of the function and growth of the technology itself now possessed and the uncertainty of changes in related technologies (complementary and alternative), thus including both static and dynamic technology risks. Although high technology has many advantages, intense competition between technologies is inevitable, and the interaction between technology and the environment makes it easy to lose its superiority, thus also devaluing the benefits. Competitiveness and process should be reflected in the concept of technology risk, so technology risk analysis should consider technology in a complex developing environment. [1] The development of a Beidou positioning-based milk powder sales management system requires appropriate technical skills, including familiarity with Beidou positioning technology, software development and database management and other related technologies. If the team has insufficient technical skills or lacks relevant experience, technical problems may occur during the development process, resulting in the system not operating properly.
If there is a problem with the information transmission or cooperation with the Beidou positioning service provider, it will lead to the lack of technical support to the customer and cause certain impact to the customer.
The platform of milk powder production and sales management system based on Beidou positioning may have certain technical problems in the initial operation, unreasonable program design, program logic operation errors, etc.
Technical risk prevention countermeasures: Selecting reliable development teams and suppliers: Selecting experienced development teams and suppliers can reduce the risk in the development process. Adequate testing during the development process can help identify and solve problems. Also, establish a quality assurance system to monitor and manage the operation of the software to ensure the stability and reliability of the software. After the software goes online, continuous improvements and upgrades are required to ensure the perfection of software functions and optimization of user experience. At the same time, vulnerabilities are fixed and security measures are strengthened in a timely manner to prevent security risks.

Data Security Risks
A data security risk is any threat or danger that could lead to unauthorized access, disclosure, destruction or misuse of data. Examples include hacker attacks, viruses and malware. The sales management system of milk powder based on Beidou positioning needs to collect and store sensitive information such as users' personal information and transaction data. If the data security mechanism of the system is not perfect or there are loopholes, it may lead to user data leakage or hacking, thus causing incalculable losses.
Data security risk prevention measures: During the development process, the security of user data needs to be protected. Encryption technology, backup data and restricted access can be used to protect data security.

Conclusion
This paper firstly introduces some major milk powder safety incidents and introduces some relevant data for illustration to emphasize the importance of milk powder safety, based on which the proposal of establishing a formula milk powder traceability system based on Beidou system positioning is proposed, and introduces the concept of traceability system and its origin, as well as the research status and development of traceability system at home and abroad, and then specifically to the research status and development of milk powder at home and abroad. Then the research is divided into three parts: 1) Beidou positioning module: using the ultra-low power consumption and extremely miniaturized locator, the distance between the satellite with known position and the user receiver is measured by the Beidou positioning system, the data of the satellite is integrated to calculate the specific position of the receiver, and then the spatial distance rear rendezvous method is adopted based on the instantaneous position of the satellite with high speed movement as the known starting data, so as to determine the milk powder location information, such as latitude and longitude, location name, etc. 2) Traceability system: using QR code as the unique index traceability code. Consumers can login to the APP client to scan the code to get the information, and then they can see the milk powder production information, which includes the traceability information flow of each link of the whole process from milk source origin to sales. 3) APP production: set up a special traceability channel on the app, and through scanning the QR code and can directly browse the production information of milk powder from production to sales, logistics information, etc., and place the company's mini online Users can purchase other products of the company through the app, and can also check the outgoing and logistics information through the app after placing orders for products. When milk powder finally reaches consumers, it goes through many links from production to sales, and problems in each link may have an impact on the quality and safety of milk powder, so it is of great significance to establish a milk powder traceability sales management system based on Beidou positioning.
