“…In addition, to verify the performance of the algorithm, the study analyzed the temporal and spatial complexity. The experimental results indicated that the method was significantly superior to existing methods in recognition efficiency [8]. To avoid the poor performance of the time division multiple access anti-collision algorithm when the number of labels was large, C Jing et al conducted simulation analysis on the performance of four anti-collision algorithms based on blind source separation.…”

In wireless sensor networks, sensing tags are battery powered, which also limits the battery life. Therefore, it is particularly important to study self powered sensing tags. At present, passive wireless identification systems can achieve self powered communication through tags.However, wireless power supply sensing systems have problems such as low efficiency and short communication distance. To reduce the power consumption of sensing tags and improve the efficiency of sensing systems, a passive wireless low-power hydrogen concentration sensing system is designed. To further reduce the power consumption of sensing tags, a passive wireless magnetic field intensity sensing system is developed.In addition, to solve the low efficiency of multiple sensing labels in wireless power supply sensing systems, an efficient anticollision algorithm based on dynamic binary query trees is designed. According to the research results, in the cold start indoor environment, the energy collection rate of the sensing tag designed in the research was 0.081mJ/s, and the energy collection efficiency was 25.7%.In single/dual sensor mode, the maximum values of sensing error were 2.1% and 5.2%, respectively. The maximum recognition time of the anticollision algorithm based on dynamic multi base query tree was 2.78s, and the minimum value was 1.31s.The research results can provide methodological and technical support for the improvement of wireless power supply sensing systems, expanding the application range of wireless power supply sensing systems.

“…The multiple readers' collision problem, that is, the interference of adjacent readers in the signal crossing area leads to the reduction of the read-write range of readers, and sometimes the tags can't be read accurately. Another multiple electronic tags' collision problem is multiple tags communicate with only one reader simultaneously (Samsami & Yasrebi, 2020).…”

Coffee machines have become very popular in recent years, but their lack of functionality still requires a great deal of manual maintenance, which inevitably has many hidden dangers. Coffee machines with radio frequency identification systems (RFID) are more effective in reducing losses due to manual labor, and increasing efficiency. However, collision problems in RFID systems can seriously affect the performance of the system. In this paper, we propose a specific solution to such problems by proposing a collision-free process technology for arrayed multipoint devices. And this technique is successfully applied in a coffee machine. Through design experiments, after 10,000 repeated tests, no collision error occurred. The problem of collisions in coffee machines with RFID mechanisms has been successfully solved.

“…The initialization phase and the verification phase are the same as other security protocols [18]. The ownership change stage is a unique stage based on the supply chain security agreement, and it is also the most important link, because it involves the update of the important secret information of the label.…”

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.
