Analysis on the practical application of active RFID real-time positioning system

　　Active RFID technology is not known to more people like passive RFID technology. Compared with passive RFID technology, active RFID technology has a longer recognition distance. Its technical characteristics, with the increasing demand for positioning by industry enterprises, have gradually become prominent and have been generally recognized in the industry. The author tracked the representative of Beijing Tianyi Zhonghe Technology Co., Ltd., the first enterprise engaged in the development, production and application of active RFID technology, and made an in-depth understanding of positioning. Below, we will make market analysis on the positioning of active RFID in different types of environments.

　　Application 1 Positioning in a closed environment

　　In a semi-enclosed or fully enclosed environment, GPS cannot play a positioning role. The positioning of active RFID in such environments has gradually been recognized by the industry and began to try to apply it, mainly in the application of personnel positioning in coal mines. Like Tianyizhonghe, some active RFID companies were the first to target the potential demand for coal mine positioning and explore how to apply active RFID technology to personnel positioning management in underground tunnels. Now, this application has been replicated on a large scale. This breakthrough victory proves the potential application of active RFID technology in other industries and brings unlimited confidence to enterprises.

　　Today, common applications of active RFID technology in closed environments include: prison personnel positioning, subway tunnel construction positioning management, and the positioning of personnel and materials in buildings or warehouses. Among them, the positioning of prison personnel is expected to become the next industry that can be replicated and promoted like the coal industry, causing some active RFID companies to compete. As for the location management of construction personnel of subway tunnels, its application environment is quite similar to that of coal mine tunnels, and it is simpler than that of coal mine tunnels. The technical implementation can basically be copied, but its market demand is extremely limited. For the positioning of personnel and materials in buildings or warehouses, its market demands are constantly emerging. For example, it is applied to the management of warehousing materials in the army, the positioning of personnel in units with high confidentiality, and the monitoring and management of whether staff are on duty. The application of enterprises in these industries has broadened the market space of active RFID, and has gradually been recognized by more and more integrators, engineering companies and even direct customers, which has greatly improved the market cultivation of active RFID technology.

　　Therefore, in positioning in a closed environment, active RFID technology has established a solid foundational advantage, and continues to dig deeper into the industry and enterprise applications with more market promotion value, in order to further expand the market coverage.

　　Application 2 outdoor area positioning

　　Although GPS is in the open air environment, it can completely realize positioning. However, the precise positioning in a small area, or the recording of fixed points on the road, such positioning requirements with different additional conditions, our commonly used GPS cannot be easily solved. Active RFID technology can install active RFID readers in some places that need special attention according to actual positioning requirements. By collecting the transmission information of the positioning object, the coverage of the reader's signal can determine the location of the object. The location, if you want to achieve precise positioning, can be combined with the use of a locator. Of course, it is possible to formulate algorithms to perform comprehensive calculations on the information collected by the positioning object, so as to obtain more accurate and effective positioning data.

　　Active RFID positioning applications in the open-air environment commonly include personnel and vehicle positioning in various parks, trajectory tracking of duty or transportation vehicles within specified road sections, and location and path tracking of the elderly and children in the community. The demand market for positioning within these domains is increasing year by year, and to meet the needs of different application situations, there are high requirements for the company’s product integration capabilities and mobility, so it is both an opportunity and an opportunity for active RFID companies. It is a challenge.

　　Application 3 indoor and outdoor combined positioning

　　The integrated active RFID positioning in the closed and open-air environment can naturally obtain the application function of indoor and outdoor combined positioning. Below I quote an actual case made by Tianyizhong to introduce the needs of combined positioning. When a student goes to school, parents want to know whether their child has entered the school normally; when at school, in many cases, the school wants to know where the student is, whether it is in a school building, a room, or a playground A certain corner, whether or not even left the school without authorization. When school is over, parents want to know when the child left the school. From judging students entering and leaving school, to grasping a certain position of students on campus, active RFID technology can seamlessly realize indoor and outdoor switching positioning.

　　This kind of indoor and outdoor combined positioning needs to realize the process positioning of the integrity and continuity of certain objects within a certain range, which has been favored by many industries. It can be said that the positioning market for active RFID has an unlimited future.
