Abstract
The logistics traceability system can cover the whole process of the product from the source of production to the consumption cycle. By distinguishing the key nodes of the product in the logistics sales process, the data information of the production and storage of the corresponding product is collected and entered at the corresponding node, so that the entire process is visible and controllable. On the basis of determining the overall system plan, this paper designs and develops the UHF RFID reader system and traceability system platform. In terms of the reader system, by analyzing its core functions and performance index requirements, the overall design scheme and frame structure of the reader system’s software and hardware are determined. The main control circuit is based on the STM32F103RET6 single-chip microcomputer; the RF transceiver circuit is based on the MagicRF M100. Simultaneously, we design a variety of communication circuits including LoRa and RJ45 to facilitate wireless communication with the traceability platform. In terms of software, through the research and analysis of the EPC Class-1 Generation-2 protocol standard, the multitag anticollision algorithm—Q algorithm—is adopted. This algorithm has the advantages of high recognition efficiency and a large number of successfully recognized tags per unit time. According to the design plan, the system is wirelessly networked in the B/S mode and the product information collected through RFID technology is transmitted to the management level to dynamically understand the information dynamics of logistics in real time. Using radio frequency, computer network, communication, and other technologies, the hardware and software systems of the system are integrated. The performance indicators of the hardware system are tested through experiments, and the design indicators are compared to prove the feasibility of the equipment application. After setting up the local area network and configuring the server configuration, the traceability system was accessed and the verification of the basic functions of the system was completed. The test results show that the low-cost universal RFID wireless logistics terminal has high accuracy and real-time performance in the process of logistics traceability.
Highlights
In the current new era of rapid development of information technology, for urban and rural construction, especially the strategy of rural revitalization, it must rely on information technology to achieve it
The research in this article is based on the emerging information technology, analyzes and improves the current cold chain logistics of Journal of Sensors aquatic products, and optimizes the traditional traceability system and traceability model to make it more convenient and efficient [3,4,5]
Analysis shows that the SRSFP+ protocol can resist tracking attacks and reader and tag counterfeiting attacks; the SRSFP + protocol meets the untraceability of forward, backward, and strong forward untraceability under the untraceable model; compared with other protocols, the security and performance are better than other protocols and can be applied to distributed environments, such as cloud database environments
Summary
In the current new era of rapid development of information technology, for urban and rural construction, especially the strategy of rural revitalization, it must rely on information technology to achieve it. In people’s daily life, the demand for products is showing a trend of rapid growth but it is not easy to preserve under traditional craftsmanship, which will lead to deterioration of quality, affect the quality of life of consumers, and threaten people’s health [1, 2] It is precisely based on this demand that the application of logistics cold chain technology is born. Because RFID technology has the characteristics of low cost and high technology in information collection, it has been studied by domestic and foreign enterprises and academia [6] They use RFID technology to implement product traceability management and trace the entire supply chain system of products to ensure the safety and quality of auto parts in the circulation link; modern Internet information technology can largely eliminate the possibility of product fraud in all links. After setting up the local area network and configuring the server configuration, the traceability system was accessed and the verification of the basic functions of the system was completed
